./log2changes.pl
Daniel (24 August 2005)
- Toby Peterson added CURLOPT_IGNORE_CONTENT_LENGTH to the library, accessible
from the command line tool with --ignore-content-length. This will make it
easier to download files from Apache 1.x (and similar) servers that are
still having problems serving files larger than 2 or 4 GB. When this option
is enabled, curl will simply have to wait for the server to close the
connection to signal end of transfer. I wrote test case 269 that runs a
simple test that this works.
- (Trying hard to exclude emotions now.) valgrind version 3 suddenly renamed
the --logfile command line option to --log-file, and thus the test script
valgrind autodetection now has yet another version check to do and then it
alters the valgrind command line accordingly.
- Fixed CA cert verification using GnuTLS with the default bundle, which
previously failed due to GnuTLS not allowing x509 v1 CA certs by default.
Daniel (19 August 2005)
- Norbert Novotny had problems with FTPS and he helped me work out a patch
that made curl run fine in his end. The key was to make sure we do the
SSL/TLS negotiation immediately after the TCP connect is done and not after
a few other commands have been sent like we did previously. I don't consider
this change necessary to obey the standards, I think this server is pickier
than what the specs allow it to be, but I can't see how this modified
libcurl code can add any problems to those who are interpreting the
standards more liberally.
Daniel (17 August 2005)
- Jeff Pohlmeyer found out that if you ask libcurl to load a cookiefile (with
CURLOPT_COOKIEFILE), add a cookie (with CURLOPT_COOKIELIST), tell it to
write the result to a given cookie jar and then never actually call
curl_easy_perform() - the given file(s) to read was never read but the
output file was written and thus it caused a "funny" result.
- While doing some tests for the bug above, I noticed that Firefox generates
large numbers (for the expire time) in the cookies.txt file and libcurl
didn't treat them properly. Now it does.
Daniel (15 August 2005)
- Added more verbose "warning" messages to the curl client for cases where it
fails to open/read files etc to help users diagnose why it doesn't do what
you'd expect it to. Converted lots of old messages to use the new generic
function I wrote for this purpose.
Daniel (13 August 2005)
- James Bursa identified a libcurl HTTP bug and a good way to repeat it. If a
site responds with bad HTTP response that doesn't contain any header at all,
only a response body, and the write callback returns 0 to abort the
transfer, it didn't have any real effect but the write callback would be
called once more anyway.
Daniel (12 August 2005)
- Based on Richard Clayton's reports, I found out that using curl -d @filename
when 'filename' was not possible to access made curl use a GET request
instead.
- The time condition illegal syntax warning is now inhibited if -s is used.
Daniel (10 August 2005)
- Mario Schroeder found out that one of the debug callbacks calls that regards
SSL data with the CURLINFO_TEXT type claimed that the data was one byte
larger than it actually is, thus falsely telling the application that the
terminating zero was part of the data.
Daniel (9 August 2005)
- Christopher R. Palmer fixed the offsets used for date parsings when the time
zone name of a daylight savings time was used. For example, PDT vs PDS. This
flaw was introduced with the new date parser (11 sep 2004 - 7.12.2).
Fortunately, no web server or cookie string etc should be using such time
zone names thus limiting the effect of this bug.
Daniel (8 August 2005)
- Jon Grubbs filed bug report #1249962 which identified a problem with NTLM on
a HTTP proxy if an FTP URL was given. libcurl now properly switches to pure
HTTP internally when an HTTP proxy is used, even for FTP URLs. The problem
would also occur with other multi-pass auth methods.
Daniel (7 August 2005)
- When curl is built with GnuTLS, curl-config didn't include "SSL" when
--features was used.
Daniel (28 July 2005)
- If any of the options CURLOPT_HTTPGET, CURLOPT_POST and CURLOPT_HTTPPOST is
set to 1, CURLOPT_NOBODY will now automatically be set to 0.
Daniel (27 July 2005)
- Dan Fandrich changes over the last week: fixed numerous minor configure
option parsing flaws: --without-gnutls, --without-spnego --without-gssapi
and --without-krb4. Spellfixed several error messages.
- Peteris Krumins added CURLOPT_COOKIELIST and CURLINFO_COOKIELIST, which is a
simple interface to extracting and setting cookies in libcurl's internal
"cookie jar". See the new cookie_interface.c example code.
Daniel (13 July 2005)
- Diego Casorran provided patches to make curl build fine on Amiga again.
Daniel (12 July 2005)
- Adrian Schuur added trailer support in the chunked encoding stream. The
trailer is then sent to the normal header callback/stream. I wrote up test
case 266 to verify the basic functionality. Do note that test case 34
contains a flawed chunked encoding stream that still works the same.
Daniel (5 July 2005)
- Gisle Vanem came up with a nice little work-around for bug #1230118. It
seems the Windows (MSVC) libc time functions may return data one hour off if
TZ is not set and automatic DST adjustment is enabled. This made
curl_getdate() return wrong value, and it also concerned internal cookie
expirations etc.
Daniel (4 July 2005)
- Andrew Bushnell provided enough info for me to tell that we badly needed to
fix the CONNECT authentication code with multi-pass auth methods (such as
NTLM) as it didn't previously properly ignore response-bodies - in fact it
stopped reading after all response headers had been received. This could
lead to libcurl sending the next request and reading the body from the first
request as response to the second request. (I also renamed the function,
which wasn't strictly necessary but...)
The best fix would to once and for all make the CONNECT code use the
ordinary request sending/receiving code, treating it as any ordinary request
instead of the special-purpose function we have now. It should make it
better for multi-interface too. And possibly lead to less code...
Added test case 265 for this. It doesn't work as a _really_ good test case
since the test proxy is too stupid, but the test case helps when running the
debugger to verify.
Daniel (30 June 2005)
- Dan Fandrich improved the configure script's ability to figure out what kind
of strerror_r() API that is used when cross-compiling. If __GLIB__ is
defined, it assumes the glibc API. If not, it issues a notice as before that
the user needs to manually edit lib/config.h for this.
Daniel (23 June 2005)
- David Shaw's fix that unifies proxy string treatment so that a proxy given
with CURLOPT_PROXY can use a http:// prefix and user + password. The user
and password fields are now also URL decoded properly. Test case 264 added
to verify.
Daniel (22 June 2005)
- David Shaw updated libcurl.m4
Daniel (14 June 2005)
- Gisle Vanem fixed a potential thread handle leak. Bug report #1216500.
Comment in http://curl.haxx.se/mail/lib-2005-06/0059.html
Daniel (13 June 2005)
- Made buildconf run libtoolize in the ares dir too (inspired by Tupone's
reverted patch).
Daniel (9 June 2005)
- Incorporated Tupone's findtool fix in buildconf (slightly edited)
- Incorporated Tupone's head -n fix in buildconf.
Daniel (8 June 2005)
- Reverted Tupone's patch again, it broke numerous autobuilds. Let's apply it
in pieces, one by one and see what we need to adjust to work all over.
Daniel (6 June 2005)
- Tupone Alfredo fixed three problems in buildconf:
1) findtool does look per tool in PATH and think ./perl is the perl
executable, while is just a local directory (I have . in the PATH)
2) I got several warning for head -1 deprecated in favour of head -n 1
3) ares directory is missing some file (missing is missing :-) ) because
automake and friends is not run.
Daniel (3 June 2005)
- Added docs/libcurl/getinfo-times, based on feedback from 'Edi':
http://curl.haxx.se/feedback/display.cgi?id=11178325798299&support=yes
- Andres Garcia provided yet another text mode patch for several test cases so
that they do text comparisions better on Windows (newline-wise).
Daniel (1 June 2005)
- The configure check for c-ares now adds the cares lib before the other libs,
to make it build fine with mingw. Inspired by Tupone Alfredo's bug report
(and patch) #1212940
Daniel (31 May 2005)
- Todd Kulesza reported a flaw in the proxy option, since a numerical IPv6
address was not possible to use. It is now, but requires it written
RFC2732-style, within brackets - which incidently is how you enter numerical
IPv6 addresses in URLs. Test case 263 added to verify.
Daniel (30 May 2005)
- Eric Cooper reported about a problem with HTTP servers that responds with
binary zeroes within the headers. They confused libcurl to do wrong so the
downloaded headers become incomplete. The fix is now verified with test case
262.
Daniel (25 May 2005)
- Fixed problems with the test suite, and in particular the FTP test cases
since it previously was failing every now and then in a nonsense manner.
- --trace-time now outputs the full microsecond, all 6 digits.
Daniel (24 May 2005)
- Andres Garcia provided a text mode patch for several test cases so that they
do text comparisions better on Windows (newline-wise).
- Any 2xx response (and not just 200) is now considered a fine response to
TYPE, as some servers obviously sends a 226 there. Added test case 261 to
verify. Based on a question/report by Georg Wicherski.
Daniel (20 May 2005)
- Improved runtests.pl to allow stdout tests to be mode=text as well, just
as file comparisons already supports. Added this info to the FILEFORMAT
docs.
Daniel (18 May 2005)
- John McGowan identified a problem in bug report #1204435 with malformed URLs
like "http://somehost?data" as it added a slash too much in the request
("GET /?data/"...). Added test case 260 to verify.
- The configure check for strerror_r() failed to detect the proper API at
times, like on HP-UX 10.20. Then lib/strerror.c badly assumed the glibc
version if the posix define wasn't set (since it _had_ found a strerror_r).
Daniel (16 May 2005)
- The gmtime_r() function in HP-UX 10.20 is broken. About 13 test cases fail
due to this. There's now a configure check that attempts to detect the bad
function and not use it on such systems.
Version 7.14.0 (16 May 2005)
Daniel (13 May 2005)
- Grigory Entin reported that curl's configure detects a fine poll() for Mac
OS X 10.4 (while 10.3 or later detected a "bad" one), but the executable
doesn't work as good as if built without poll(). I've adjusted the configure
to always skip the fine-poll() test on Mac OS X (darwin).
Daniel (12 May 2005)
- When doing a second request (after a disconnect) using the same easy handle,
over a proxy that uses NTLM authentication, libcurl failed to use NTLM again
properly (the auth method was accidentally reset to the same as had been set
for host auth, which defaults to Basic). Bug report #1200661 identified the
the problem and the fix.
- If -z/--time-cond is used with an invalid date syntax, this is no longer
silently discarded. Instead a proper warning message is diplayed that
informs about it. But it still continues without the condition.
Version 7.14.0-pre2 (11 May 2005)
Daniel (11 May 2005)
- Starting now, libcurl sends a little different set of headers in its default
HTTP requests:
A) Normal non-proxy HTTP:
- no more "Pragma: no-cache" (this only makes sense to proxies)
B) Non-CONNECT HTTP request over proxy:
- "Pragma: no-cache" is used (like before)
- "Proxy-Connection: Keep-alive" (for older style 1.0-proxies)
C) CONNECT HTTP request over proxy:
- "Host: [name]:[port]"
- "Proxy-Connection: Keep-alive"
The A) case is mostly to reduce the default header size and remove a
pointless header.
The B) is to address (rare) problems with HTTP 1.0 proxies
The C) headers are both to address (rare) problems with some proxies. The
code in libcurl that deals with CONNECT requests need a rewrite, but it
feels like a too big a job for me to do now. Details are added in the code
comments for now.
Updated a large amount of test cases to reflect the news.
Daniel (10 May 2005)
- Half-baked attempt to bail out if select() returns _only_ errorfds when the
transfer is in progress. An attempt to fix Allan's problem. See
http://curl.haxx.se/mail/lib-2005-05/0073.html and the rest of that thread
for details.
I'm still not sure this is the right fix, but...
Version 7.14.0-pre1 (9 May 2005)
Daniel (2 May 2005)
- Sort of "fixed" KNOWN_BUGS #4: curl now builds IPv6 enabled on AIX 4.3. At
least it should no longer cause a compiler error. However, it does not have
AI_NUMERICHOST so we cannot getaddrinfo() any numerical addresses with it
(we use that for FTP PORT/EPRT)! So, I modified the configure check that
checks if the getaddrinfo() is working, to use AI_NUMERICHOST since then
it'll fail on AIX 4.3 and it will automatically build with IPv6 support
disabled.
- Added --trace-time that when used adds a time stamp to each trace line that
--trace, --trace-ascii and --verbose output. I also made the '>' display
separate each line on the linefeed so that HTTP requests etc look nicer in
the -v output.
- Made curl recognize the environment variables Lynx (and others?) support for
pointing out the CA cert path/file: SSL_CERT_DIR and SSL_CERT_FILE. If
CURL_CA_BUNDLE is not set, they are checked afterwards.
Like before: on windows if none of these are set, it checks for the ca cert
file like this:
1. application's directory
2. current working directory
3. Windows System directory (e.g. C:\windows\system32)
4. Windows Directory (e.g. C:\windows)
5. all directories along %PATH%
Daniel (1 May 2005)
- The runtests.pl script now starts test servers by doing fork() and exec()
instead of the previous approach. This is less complicated and should
hopefully lead to less "leaked" servers (servers that aren't stopped
properly when the tests are stopped).
- Alexander Zhuravlev found a case when you did "curl -I [URL]" and it
complained on the chunked encoding, even though a HEAD should never return a
body and thus it cannot be a chunked-encoding problem!
Daniel (30 April 2005)
- Alexander Zhuravlev found out that (lib)curl SIGSEGVed when using
--interface on an address that can't be bound.
Daniel (28 April 2005)
- Working on fixing up test cases to mark sections as 'mode=text' for things
that curl writes as text files, since then they can get different line
endings depending on OS. Andrés García helps me work this out.
Did lots of other minor tweaks on the test scripts to work better and more
reliably find test servers and also kill test servers.
- Dan Fandrich pointed out how the runtests.pl script killed the HTTP server
instead of the HTTPS server when closing it down.
Daniel (27 April 2005)
- Paul Moore made curl check for the .curlrc file (_curlrc on windows) on two
more places. First, CURL_HOME is a new environment variable that is used
instead of HOME if it is set, to point out where the default config file
lives. If there's no config file in the dir pointed out by one of the
environment variables, the Windows version will instead check the same
directory the executable curl is located in.
Daniel (26 April 2005)
- Cory Nelson's work on nuking compiler warnings when building on x64 with
VS2005.
Daniel (25 April 2005)
- Fred New reported a bug where we used Basic auth and user name and password
in .netrc, and when following a Location: the subsequent requests didn't
properly use the auth as found in the netrc file. Added test case 257 to
verify my fix.
- Based on feedback from Cory Nelson, I added some preprocessor magic in
*/setup.h and */config-win32.h to build fine with VS2005 on x64.
Daniel (23 April 2005)
- Alex Suykov made the curl tool now assume that uploads using HTTP:// or
HTTPS:// are the only ones that show output and thus motivates a switched
off progress meter if the output is sent to the terminal. This makes FTP
uploads without '>', -o or -O show the progress meter.
Daniel (22 April 2005)
- Dave Dribin's MSVC makefile fix: set CURL_STATICLIB when it builds static
library variants.
- Andres Garcia fixed configure to set the proper define when building static
libcurl on windows.
- --retry-delay didn't work.
Daniel (18 April 2005)
- Olivier reported that even though he used CURLOPT_PORT, libcurl clearly
still used the default port. He was right. I fixed the problem and added the
test cases 521, 522 and 523 to verify the fix.
- Toshiyuki Maezawa reported that when doing a POST with a read callback,
libcurl didn't properly send an Expect: 100-continue header. It does now.
- I committed by mig change in the test suite's FTP server that moves out all
socket/TCP code to a separate C program named sockfilt. And added 4 new
test cases for FTP over IPv6.
Daniel (8 April 2005)
- Cory Nelson reported a problem with a HTTP server that responded with a 304
response containing an "illegal" Content-Length: header, which was not
properly ignored by libcurl. Now it is. Test case 249 verifies.
Daniel (7 April 2005)
- Added ability to build and run with GnuTLS as an alternative to OpenSSL for
the secure layer. configure --with-gnutls enables with. Note that the
previous OpenSSL check still has preference and if it first detects OpenSSL,
it will not check for GnuTLS. You may need to explictly diable OpenSSL with
--without-ssl.
This work has been sponsored by The Written Word.
Daniel (5 April 2005)
- Christophe Legry fixed the post-upload check for FTP to not complain if the
upload was skipped due to a time-condition as set with
CURLOPT_TIMECONDITION. I added test case 247 and 248 to verify.
Version 7.13.2 (5 April 2005)
Daniel (4 April 2005)
- Marcelo Juchem fixed the MSVC makefile for libcurl
- Gisle Vanem fixed a crash in libcurl, that could happen if the easy handle
was killed before the threading resolver (windows only) still hadn't
completed.
- Hardeep Singh reported a problem doing HTTP POST with Digest. (It was
actually also affecting NTLM and Negotiate.) It turned out that if the
server responded with 100 Continue before the initial 401 response, libcurl
didn't take care of the response properly. Test case 245 and 246 added to
verify this.
Daniel (30 March 2005)
- Andres Garcia modified the configure script to check for libgdi32 before
libcrypto, to make the SSL check work fine on msys/mingw.
Daniel (29 March 2005)
- Tom Moers identified a flaw when you sent a POST with Digest authentication,
as in the first request when curl sends a POST with Content-Length: 0, it
still forcibly closed the connection before doing the next step in the auth
negotiation.
- Jesper Jensen found out that FTP-SSL didn't work since my FTP
rewrite. Fixing that was easy, but it also revealed a much worse problem:
the FTP server response reader function didn't properly deal with reading
responses in multiple tiny chunks properly! I modified the FTP server to
allow it to produce such split-up responses to make sure curl deals with
them as it should.
- Based on Augustus Saunders' comments and findings, the HTTP output auth
function was fixed to use the proper proxy authentication when multiple ones
are accepted. test 239 and test 243 were added to repeat the problems and
verify the fixes.
--proxy-anyauth was added to the curl tool
Daniel (16 March 2005)
- Tru64 and some IRIX boxes seem to not like test 237 as it is. Their
inet_addr() functions seems to use &255 on all numericals in a ipv4 dotted
address which makes a different failure... Now I've modified the ipv4
resolve code to use inet_pton() instead in an attempt to make these systems
better detect this as a bad IP address rather than creating a toally bogus
address that is then passed on and used.
Daniel (15 March 2005)
- Dan Fandrich made the code properly use the uClibc's version of
inet_ntoa_r() when built with it.
- Added test 237 and 238: test EPSV and PASV response handling when they get
well- formated data back but using illegal values. In 237 PASV gets an IP
address that is way bad. In 238 EPSV gets a port that is way out of range.
Daniel (14 March 2005)
- Added a few missing features to the curl-config --features list
- Modified testcurl.pl to now offer
1 - command line options for all info it previously only read from
file: --name, --email, --desc and --configure
2 - --nocvsup makes it not attempt to do cvs update
3 - --crosscompile informs it and makes it not attempt things it can't do
- Fixed numerous win32 compiler warnings.
- Removed the lib/security.h file since it shadowed the mingw/win32 header
with the same name which is needed for SSPI builds. The contents of the
former security.h is now i krb4.h
- configure --enable-sspi now enables SSPI in the build. It only works for
windows builds (including cross-compiles for windows).
Daniel (12 March 2005)
- David Houlder added --form-string that adds that string to a multipart
formpost part, without special characters having special meanings etc like
--form features.
Daniel (11 March 2005)
- curl_version_info() returns the feature bit CURL_VERSION_SSPI if it was
built with SSPI support.
- Christopher R. Palmer made it possible to build libcurl with the
USE_WINDOWS_SSPI on Windows, and then libcurl will be built to use the
native way to do NTLM. SSPI also allows libcurl to pass on the current user
and its password in the request.
Daniel (9 March 2005)
- Dan F improved the SSL lib setup in configure.
- Nodak Sodak reported a crash when using a SOCKS4 proxy.
- Jean-Marc Ranger pointed out an embarassing debug printf() leftover in the
multi interface code.
- Adjusted the man page for the curl_getdate() return value for dates after
year 2038. For 32 bit time_t it returns 0x7fffffff but for 64bit time_t it
returns either the correct value or even -1 on some systems that still seem
to not deal with this properly. Tor Arntsen found a 64bit AIX system for us
that did the latter. Gwenole Beauchesne's Mandrake patch put the lights on
this problem in the first place.
Daniel (8 March 2005)
- Dominick Meglio reported that using CURLOPT_FILETIME when transferring a FTP
file got a Last-Modified: header written to the data stream, corrupting the
actual data. This was because some conditions from the previous FTP code was
not properly brought into the new FTP code. I fixed and I added test case
520 to verify. (This bug was introduced in 7.13.1)
- Dan Fandrich fixed the configure --with-zlib option to always consider the
given path before any standard paths.
Daniel (6 March 2005)
- Randy McMurchy was the first to report that valgrind.pm was missing from the
release archive and thus 'make test' fails.
Daniel (5 March 2005)
- Dan Fandrich added HAVE_FTRUNCATE to several config-*.h files.
- Added test case 235 that makes a resumed upload of a file that isn't present
on the remote side. This then converts the operation to an ordinary STOR
upload. This was requested/pointed out by Ignacio Vazquez-Abrams.
It also proved (and I fixed) a bug in the newly rewritten ftp code (and
present in the 7.13.1 release) when trying to resume an upload and the
servers returns an error to the SIZE command. libcurl then loops and sends
SIZE commands infinitely.
- Dan Fandrich fixed a SSL problem introduced on February 9th that made
libcurl attempt to load the whole random file to seed the PRNG. This is
really bad since this turns out to be using /dev/urandom at times...
Version 7.13.1 (4 March 2005)
Daniel (4 March 2005)
- Dave Dribin made it possible to set CURLOPT_COOKIEFILE to "" to activate
the cookie "engine" without having to provide an empty or non-existing file.
- Rene Rebe fixed a -# crash when more data than expected was retrieved.
Daniel (22 February 2005)
- NTLM and ftp-krb4 buffer overflow fixed, as reported here:
http://www.securityfocus.com/archive/1/391042 and the CAN report here:
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0490
If these security guys were serious, we'd been notified in advance and we
could've saved a few of you a little surprise, but now we weren't.
Daniel (19 February 2005)
- Ralph Mitchell reported a flaw when you used a proxy with auth, and you
requested data from a host and then followed a redirect to another
host. libcurl then didn't use the proxy-auth properly in the second request,
due to the host-only check for original host name wrongly being extended to
the proxy auth as well. Added test case 233 to verify the flaw and that the
fix removed the problem.
Daniel (18 February 2005)
- Mike Dobbs reported a mingw build failure due to the lack of
BUILDING_LIBCURL being defined when libcurl is built. Now this is defined by
configure when mingw is used.
Daniel (17 February 2005)
- David in bug report #1124588 found and fixed a socket leak when libcurl
didn't close the socket properly when returning error due to failing
localbind
Daniel (16 February 2005)
- Christopher R. Palmer reported a problem with HTTP-POSTing using "anyauth"
that picks NTLM. Thanks to David Byron letting me test NTLM against his
servers, I could quickly repeat and fix the problem. It turned out to be:
When libcurl POSTs without knowing/using an authentication and it gets back
a list of types from which it picks NTLM, it needs to either continue
sending its data if it keeps the connection alive, or not send the data but
close the connection. Then do the first step in the NTLM auth. libcurl
didn't send the data nor close the connection but simply read the
response-body and then sent the first negotiation step. Which then failed
miserably of course. The fixed version forces a connection if there is more
than 2000 bytes left to send.
Daniel (14 February 2005)
- The configure script didn't check for ENGINE_load_builtin_engines() so it
was never used.
Daniel (11 February 2005)
- Removed all uses of strftime() since it uses the localised version of the
week day names and month names and servers don't like that.
Daniel (10 February 2005)
- Now the test script disables valgrind-testing when the test suite runs if
libcurl is built shared. Otherwise valgrind only tests the shell that runs
the wrapper-script named 'curl' that is a front-end to curl in this case.
This should also fix the huge amount of reports of false positives when
valgrind has identified leaks in (ba)sh and not in curl and people report
that as curl bugs. Bug report #1116672 is one example.
Also, the valgrind report parser has been adapted to check that at least one
of the sources in a stack strace is one of (lib)curl's source files or
otherwise it will not consider the problem to concern (lib)curl.
- Marty Kuhrt streamlined the VMS build.
Daniel (9 February 2005)
- David Byron fixed his SSL problems, initially mentioned here:
http://curl.haxx.se/mail/lib-2005-01/0240.html. It turned out we didn't use
SSL_pending() as we should.
- Converted lots of FTP code to a statemachine, so that the multi interface
doesn't block while communicating commands-responses with an FTP server.
I've added a comment like BLOCKING in the code on all spots I could find
where we still have blocking operations. When we change curl_easy_perform()
to use the multi interface, we'll also be able to simplify the code since
there will only be one "internal interface".
While doing this, I've now made CURLE_FTP_ACCESS_DENIED separate from the
new CURLE_LOGIN_DENIED. The first one is now access denied to a function,
like changing directory or retrieving a file, while the second means that we
were denied login.
The CVS tag 'before_ftp_statemachine' was set just before this went in, in
case of future need.
- Gisle made the DICT code send CRLF and not just LF as the spec says so.
Daniel (8 February 2005)
- Gisle fixed problems when libcurl runs out of memory, and worked on making
sure the proper error code is returned for those occations.
Daniel (7 February 2005)
- Maruko pointed out a problem with inflate decompressing exactly 64K
contents.
Daniel (5 February 2005)
- Eric Vergnaud found a use of an uninitialised variable in the ftp when doing
PORT on ipv6-enabled hosts.
- David Byron pointed out we could use BUFSIZE to read data (in
lib/transfer.c) instead of using BUFSIZE -1.
Version 7.13.0 (1 February 2005)
Daniel (31 January 2005)
- Added Lars Nilsson's htmltitle.cc example
Daniel (30 January 2005)
- Fixed a memory leak when using the multi interface and the DO operation
failed (as in test case 205).
- Fixed a valgrind warning for file:// operations.
- Fixed a valgrind report in the url globbing code for the curl command line
tool.
- Bugfixed the parser that scans the valgrind report outputs (in runtests.pl).
I noticed that it previously didn't detect and report the "Conditional jump
or move depends on uninitialised value(s)" error. When I fixed this, I
caught a few curl bugs with it. And then I had to spend time to make the
test suite IGNORE these errors when OpenSSL is used since it produce massive
amounts of valgrind warnings (but only of the "Conditional..." kind it
seems). So, if a test that requires SSL is run, it ignores the
"Conditional..." errors, and you'll get a "valgrind PARTIAL" output instead
of "valgrind OK".
Daniel (29 January 2005)
- Using the multi interface, and doing a requsted a re-used connection that
gets closed just after the request has been sent failed and did not re-issue
a request on a fresh reconnect like the easy interface did. Now it does!
- Define CURL_MULTIEASY when building libcurl (lib/easy.c to be exact), to use
my new curl_easy_perform() that uses the multi interface to run the
request. It is a great testbed for the multi interface and I believe we
shall do it this way for real in the future when we have a successor to
curl_multi_fdset(). I've used this approach to detect and fix several of the
recent multi-interfaces issues.
- Adjusted the KNOWN_BUGS #17 fix a bit more since the FTP code also did some
bad assumptions.
- multi interface: when a request is denied due to "Maximum redirects
followed" libcurl leaked the last Location: URL.
- Connect failures with the multi interface was often returned as "connect()
timed out" even though the reason was different.
Daniel (28 January 2005)
- KNOWN_BUGS #17 fixed. A DNS cache entry may not remain locked between two
curl_easy_perform() invokes. It was previously unlocked at disconnect, which
could mean that it remained locked between multiple transfers. The DNS cache
may not live as long as the connection cache does, as they are separate.
To deal with the lack of DNS (host address) data availability in re-used
connections, libcurl now keeps a copy of the IP adress as a string, to be
able to show it even on subsequent requests on the same connection.
The problem could be made to appear with this stunt:
1. create a multi handle
2. add an easy handle
3. fetch a URL that is persistent (leaves the connection alive)
4. remove the easy handle from the multi
5. kill the multi handle
6. create a multi handle
7. add the same easy handle to the new multi handle
8. fetch a URL from the same server as before (re-using the connection)
- Stephen More pointed out that CURLOPT_FTPPORT and the -P option didn't work
when built ipv6-enabled. I've now made a fix for it. Writing test cases for
custom port hosts turned too tricky so unfortunately there's none.
Daniel (25 January 2005)
- Ian Ford asked about support for the FTP command ACCT, and I discovered it
is present in RFC959... so now (lib)curl supports it as well. --ftp-account
and CURLOPT_FTP_ACCOUNT set the account string. (The server may ask for an
account string after PASS have been sent away. The client responds
with "ACCT [account string]".) Added test case 228 and 229 to verify the
functionality. Updated the test FTP server to support ACCT somewhat.
- David Shaw contributed a fairly complete and detailed autoconf test you can
use to detect libcurl and setup variables for the protocols the installed
libcurl supports: docs/libcurl/libcurl.m4
Daniel (21 January 2005)
- Major FTP third party transfer overhaul.
These four options are now obsolete: CURLOPT_SOURCE_HOST,
CURLOPT_SOURCE_PATH, CURLOPT_SOURCE_PORT (this option didn't work before)
and CURLOPT_PASV_HOST.
These two options are added: CURLOPT_SOURCE_URL and CURLOPT_SOURCE_QUOTE.
The target-side didn't use the proper path with RETR, and thus this only
worked correctly in the login path (i.e without doing any CWD). The source-
side still uses a wrong path, but the fix for this will need to wait. Verify
the flaw by using a source URL with included %XX-codes.
Made CURLOPT_FTPPORT control weather the target operation should use PORT
(or not). The other side thus uses passive (PASV) mode.
Updated the ftp3rdparty.c example source to use the updated options.
Added support for a second FTP server in the test suite. Named... ftp2.
Added test cases 230, 231 and 232 as a few first basic tests of very simple
3rd party transfers.
Changed the debug output to include 'target' and 'source' when a 3rd party
is being made, to make it clearer what commands/responses came on what
connection.
Added three new command line options: --3p-url, --3p-user and --3p-quote.
Documented the command line options and the curl_easy_setopt options related
to third party transfers.
(Temporarily) disabled the ability to re-use an existing connection for the
source connection. This is because it needs to force a new in case the
source and target is the same host, and the host name check is trickier now
when the source is identified with a full URL instead of a plain host name
like before.
TODO (short-term) for 3rd party transfers: quote support. The options are
there, we need to add test cases to verify their functionality.
TODO (long-term) for 3rd party transfers: IPv6 support (EPRT and EPSV etc)
and SSL/TSL support.
Daniel (20 January 2005)
- Philippe Hameau found out that -Q "+[command]" didn't work, although some
code was written for it. I fixed and added test case 227 to verify it.
The curl.1 man page didn't mention the '+' so I added it.
Daniel (19 January 2005)
- Stephan Bergmann made libcurl return CURLE_URL_MALFORMAT if an FTP URL
contains %0a or %0d in the user, password or CWD parts. (A future fix would
include doing it for %00 as well - see KNOWN_BUGS for details.) Test case
225 and 226 were added to verify this
- Stephan Bergmann pointed out two flaws in libcurl built with HTTP disabled:
1) the proxy environment variables are still read and used to set HTTP proxy
2) you couldn't disable http proxy with CURLOPT_PROXY (since the option was
disabled). This is important since apps may want to disable HTTP proxy
without actually knowing if libcurl was built to disable HTTP or not.
Based on Stephan's patch, both these issues should now be fixed.
Daniel (18 January 2005)
- Cody Jones' enhanced version of Samuel Díaz García's MSVC makefile patch was
applied.
Daniel (16 January 2005)
- Alex aka WindEagle pointed out that when doing "curl -v dictionary.com", curl
assumed this used the DICT protocol. While guessing protocols will remain
fuzzy, I've now made sure that the host names must start with "[protocol]."
for them to be a valid guessable name. I also removed "https" as a prefix
that indicates HTTPS, since we hardly ever see any host names using that.
Daniel (13 January 2005)
- Inspired by Martijn Koster's patch and example source at
http://www.greenhills.co.uk/mak/gentoo/curl-eintr-bug.c, I now made the
select() and poll() calls properly loop if they return -1 and errno is
EINTR. glibc docs for this is found here:
http://www.gnu.org/software/libc/manual/html_node/Interrupted-Primitives.html
This last link says BSD doesn't have this "effect". Will there be a problem
if we do this unconditionally?
Daniel (11 January 2005)
- Dan Torop cleaned up a few no longer used variables from David Phillips'
select() overhaul fix.
- Cyrill Osterwalder posted a detailed analysis about a bug that occurs when
using a custom Host: header and curl fails to send a request on a re-used
persistent connection and thus creates a new connection and resends it. It
then sent two Host: headers. Cyrill's analysis was posted here:
http://curl.haxx.se/mail/archive-2005-01/0022.html
- Bruce Mitchener identified (bug report #1099640) the never-ending SOCKS5
problem with the version byte and the check for bad versions. Bruce has lots
of clues on this, and based on his suggestion I've now removed the check of
that byte since it seems to be able to contain 1 or 5.
Daniel (10 January 2005)
- Pavel Orehov reported memory problems with the multi interface in bug report
#1098843. In short, a shared DNS cache was setup for a multi handle and when
the shared cache was deleted before the individual easy handles, the latter
cleanups caused read/writes to already freed memory.
- Hzhijun reported a memory leak in the SSL certificate code, that leaked the
remote certificate name when it didn't match the used host name.
Gisle (8 January 2005)
- Added Makefile.Watcom files (src/lib). Updated Makefile.dist.
Daniel (7 January 2005)
- Improved the test script's valgrind log parser to actually work! Also added
the ability to disable the log scanner for specific test cases. Test case
509 results in numerous problems and leaks in OpenSSL and has to get it
disabled.
Daniel (6 January 2005)
- Fixed a single-byte read out of bounds in test case 39 in the curl tool code
(i.e not in the library).
- Bug report #1097019 identified a problem when doing -d "data" with -G and
sending it to two URLs with {}. Added test 199 to verify the fix.
Daniel (4 January 2005)
- Marty Kuhrt adjusted a VMS build script slightly
- Kai Sommerfeld and Gisle Vanem fixed libcurl to build with IPv6 support on
Win2000.
Daniel (2 January 2005)
- Alex Neblett updated the MSVC makefiles slightly.

Daniel (28 December 1999):
- Tim Verhoeven correctly identified that curl
doesn't support URL formatted file names when getting ftp. Now, there's a
problem with getting very weird file names off FTP servers. RFC 959 defines
that the file name syntax to use should be the same as in the native OS of
the server. Since we don't know the peer server system we currently just
translate the URL syntax into plain letters. It is still better and with
the solaris 2.6-supplied ftp server it works with spaces in the file names.
Daniel (27 December 1999):
- When curl parsed cookies straight off a remote site, it corrupted the input
data, which, if the downloaded headers were stored made very odd characters
in the saved data. Correctly identified and reported by Paul Harrington.
Daniel (13 December 1999):
- General cleanups in the library interface. There had been some bad kludges
added during times of stress and I did my best to clean them off. It was
both regarding the lib API as well as include file confusions.
Daniel (3 December 1999):
- A small --stderr bug was reported by Eetu Ojanen...
- who also brought the suggestion of extending the -X flag to ftp list as
well. So, now it is and the long option is now --request instead. It is
only for ftp list for now (and the former http stuff too of course).
Lars J. Aas (24 November 1999):
- Patched curl to compile and build under BeOS. Doesn't work yet though!
- Corrected the Makefile.am files to allow putting object files in
different directories than the sources.
Version 6.3.1
Daniel (23 November 1999):
- I've had this major disk crash. My good old trust-worthy source disk died
along with the machine that hosted it. Thank goodness most of all the
things I've done are either backed up elsewhere or stored in this CVS
server!
- Michael S. Steuer pointed out a bug in the -F handling
that made curl hang if you posted an empty variable such as '-F name='. It
was one of those old bugs that never have worked properly...
- Jason Baietto pointed out a general flaw in the HTTP
download. Curl didn't complain if it was prematurely aborted before the
entire download was completed. It does now.
Daniel (19 November 1999):
- Chris Maltby very accurately criticized the lack of
return code checks on the fwrite() calls. I did a thorough check for all
occurrences and corrected this.
Daniel (17 November 1999):
- Paul Harrington pointed out that the -m/--max-time option
doesn't work for the slow system calls like gethostbyname()... I don't have
any good fix yet, just a slightly less bad one that makes curl exit hard
when the timeout is reached.
- Bjorn Reese helped me point out a possible problem that might be the reason
why Thomas Hurst experience problems in his Amiga version.
Daniel (12 November 1999):
- I found a crash in the new cookie file parser. It crashed when you gave
a plain http header file as input...
Version 6.3
Daniel (10 November 1999):
- I kind of found out that the HTTP time-conditional GETs (-z) aren't always
respected by the web server and the document is therefore sent in whole
again, even though it doesn't match the requested condition. After reading
section 13.3.4 of RFC 2616, I think I'm doing the right thing now when I do
my own check as well. If curl thinks the condition isn't met, the transfer
is aborted prematurely (after all the headers have been received).
- After comments from Robert Linden I also rewrote some parts of the man page
to better describe how the -F works.
- Michael Anti put up a new curl download mirror in
China: http://www.pshowing.com/curl/
- I added the list of download mirrors to the README file
- I did add more explanations to the man page
Daniel (8 November 1999):
- I made the -b/--cookie option capable of reading netscape formatted cookie
files as well as normal http-header files. It should be able to
transparently figure out what kind of file it got as input.
Daniel (29 October 1999):
- Another one of Sebastiaan van Erk's ideas (that has been requested before
but I seem to have forgotten who it was), is to add support for ranges in
FTP downloads. As usual, one request is just a request, when they're two
it is a demand. I've added simple support for X-Y style fetches. X has to
be the lower number, though you may omit one of the numbers. Use the -r/
--range switch (previously HTTP-only).
- Sebastiaan van Erk suggested that curl should be
able to show the file size of a specified file. I think this is a splendid
idea and the -I flag is now working for FTP. It displays the file size in
this manner:
Content-Length: XXXX
As it resembles normal headers, and leaves us the opportunity to add more
info in that display if we can come up with more in the future! It also
makes sense since if you access ftp through a HTTP proxy, you'd get the
file size the same way.
I changed the order of the QUOTE command executions. They're now executed
just after the login and before any other command. I made this to enable
quote commands to run before the -I stuff is done too.
- I found out that -D/--dump-header and -V/--version weren't documented in
the man page.
- Many HTTP/1.1 servers do not support ranges. Don't ask me why. I did add
some text about this in the man page for the range option. The thread in
the mailing list that started this was initiated by Michael Anti.
- I get reports about nroff crashes on solaris 2.6+ when displaying the curl
man page. Switch to gnroff instead, it is reported to work(!). Adam Barclay
reported and brought the suggestion.
- In a dialogue with Johannes G. Kristinsson we came
up with the idea to let -H/--header specified headers replace the
internally generated headers, if you happened to select to add a header
that curl normally uses by itself. The advantage with this is not entirely
obvious, but in Johannes' case it means that he can use another Host: than
the one curl would set.
Daniel (27 October 1999):
- Jongki Suwandi brought a nice patch for (yet another) crash when following
a location:. This time you had to follow a https:// server's redirect to
get the core.
Version 6.2
Daniel (21 October 1999):
- I think I managed to remove the suspicious (nil) that has been seen just
before the "Host:" in HTTP requests when -v was used.
- I found out that if you followed a location: when using a proxy, without
having specified http:// in the URL, the protocol part was added once again
when moving to the next URL! (The protocol part has to be added to the
URL when going through a proxy since it has no protocol-guessing system
such as curl has.)
- Benjamin Ritcey reported a core dump under solaris 2.6
with OpenSSL 0.9.4. It turned out this was due to a bad free() in main.c
that occurred after the download was done and completed.
- Benjamin found ftp downloads to show the first line of the download meter
to get written twice, and I removed that problem. It was introduced with
the multiple URL support.
- Dan Zitter correctly pointed out that curl 6.1 and earlier versions didn't
honor RFC 2616 chapter 4 section 2, "Message Headers": "...Field names are
case-insensitive..." HTTP header parsing assumed a certain casing. Dan
also provided me with a patch that corrected this, which I took the liberty
of editing slightly.
- Dan Zitter also provided a nice patch for config.guess to better recognize
the Mac OS X
- Dan also corrected a minor problem in the lib/Makefile that caused linking
to fail on OS X.
Daniel (19 October 1999):
- Len Marinaccio came up with some problems with curl. Since Windows has a
crippled shell, it can't redirect stderr and that causes trouble. I added
--stderr today which allows the user to redirect the stderr stream to a
file or stdout.
Daniel (18 October 1999):
- The configure script now understands the '--without-ssl' flag, which now
totally disable SSL/https support. Previously it wasn't possible to force
the configure script to leave SSL alone. The previous functionality has
been retained. Troy Engel helped test this new one.
Version 6.1
Daniel (17 October 1999):
- I ifdef'ed or commented all the zlib stuff in the sources and configure
script. It turned out we needed to mock more with zlib than I initially
thought, to make it capable of downloading compressed HTTP documents and
uncompress them on the fly. I didn't mean the zlib parts of curl to become
more than minor so this means I halt the zlib expedition for now and wait
until someone either writes the code or zlib gets updated and better
adjusted for this kind of usage. I won't get into details here, but a
short a summary is suitable:
- zlib can't automatically detect whether to use zlib or gzip
decompression methods.
- zlib is very neat for reading gzipped files from a file descriptor,
although not as nice for reading buffer-based data such as we would
want it.
- there are still some problems with the win32 version when reading from
a file descriptor if that is a socket
Daniel (14 October 1999):
- Moved the (external) include files for libcurl into a subdirectory named
curl and adjusted all #include lines to use <curl/XXXX> to maintain a
better name space and control of the headers. This has been requested.
Daniel (12 October 1999):
- I modified the 'maketgz' script to perform a 'make' too before a release
archive is put together in an attempt to make the time stamps better and
hopefully avoid the double configure-running that use to occur.
Daniel (11 October 1999):
- Applied Jörn's patches that fixes zlib for mingw32 compiles as well as
some other missing zlib #ifdef and more text on the multiple URL docs in
the man page.
Version 6.1beta
Daniel (6 October 1999):
- Douglas E. Wegscheid sent me a patch that made the exact same thing as I
just made: the -d switch is now capable of reading post data from a named
file or stdin. Use it similarly to the -F. To read the post data from a
given file:
curl -d @path/to/filename www.postsite.com
or let curl read it out from stdin:
curl -d @- www.postit.com
Jörn Hartroth (3 October 1999):
- Brought some more patches for multiple URL functionality. The MIME
separation ideas are almost scrapped now, and a custom separator is being
used instead. This is still compile-time "flagged".
Daniel
- Updated curl.1 with multiple URL info.
Daniel (30 September 1999):
- Felix von Leitner brought openssl-check fixes for configure.in to work
out-of-the-box when the openssl files are installed in the system default
dirs.
Daniel (28 September 1999)
- Added libz functionality. This should enable decompressing gzip, compress
or deflate encoding HTTP documents. It also makes curl send an accept that
it accepts that kind of encoding. Compressed contents usually shortens
download time. I *need* someone to tell me a site that uses compressed HTTP
documents so that I can test this out properly.
- As a result of the adding of zlib awareness, I changed the version string
a little. I plan to add openldap version reporting in there too.
Daniel (17 September 1999)
- Made the -F option allow stdin when specifying files. By using '-' instead
of file name, the data will be read from stdin.
Version 6.0
Daniel (13 September 1999)
- Added -X/--http-request <request> to enable any HTTP command to be sent.
Do not that your server has to support the exact string you enter. This
should possibly a string like DELETE or TRACE.
- Applied Douglas' mingw32-fixes for the makefiles.
Daniel (10 September 1999)
- Douglas E. Wegscheid pointed out a problem. Curl didn't check the FTP
servers return code properly after the --quote commands were issued. It
took anything non 200 as an error, when all 2XX codes should be accepted as
OK.
- Sending cookies to the same site in multiple lines like curl used to do
turned out to be bad and breaking the cookie specs. Curl now sends all
cookies on a single Cookie: line. Curl is not yet RFC 2109 compliant, but I
doubt that many servers do use that syntax (yet).
Daniel (8 September 1999)
- Jörn helped me make sure it still compiles nicely with mingw32 under win32.
Daniel (7 September 1999)
- FTP upload through proxy is now turned into a HTTP PUT. Requested by
Stefan Kanthak.
- Added the ldap files to the .m32 makefile.
Daniel (3 September 1999)
- Made cookie matching work while using HTTP proxy.
Bjorn Reese (31 August 1999)
- Passed his ldap:// patch. Note that this requires the openldap shared
library to be installed and that LD_LIBRARY_PATH points to the
directory where the lib will be found when curl is run with a
ldap:// URL.
Jörn Hartroth (31 August 1999)
- Made the Mingw32 makefiles into single files.
- Made file:// work for Win32. The same code is now used for unix as well for
performance reasons.
Douglas E. Wegscheid (30 August 1999)
- Patched the Mingw32 makefiles for SSL builds.
Matthew Clarke (30 August 1999)
- Made a cool patch for configure.in to allow --with-ssl to specify the
root dir of the openssl installation, as in
./configure --with-ssl=/usr/ssl_here
- Corrected the 'reconf' script to work better with some shells.
Jörn Hartroth (26 August 1999)
- Fixed the Mingw32 makefiles in lib/ and corrected the file.c for win32
compiles.
Version 5.11
Daniel (25 August 1999)
- John Weismiller pointed out a bug in the header-line
realloc() system in download.c.
- I added lib/file.[ch] to offer a first, simple, file:// support. It
probably won't do much good on win32 system at this point, but I see it
as a start.
- Made the release archives get a Makefile in the root dir, which can be
used to start the compiling/building process easier. I haven't really
changed any INSTALL text yet, I wanted to get some feed-back on this
first.
Daniel (17 August 1999)
- Another Location: bug. Curl didn't do proper relative locations if the
original URL had cgi-parameters that contained a slash. Nusu's page
again.
- Corrected the NO_PROXY usage. It is a list of substrings that if one of
them matches the tail of the host name it should connect to, curl should
not use a proxy to connect there. Pointed out to me by Douglas
E. Wegscheid. I also changed the README text a little regarding this.
Daniel (16 August 1999)
- Fixed a memory bug with http-servers that sent Location: to a Location:
page. Nusu's page showed this too.
- Made cookies work a lot better. Setting the same cookie name several times
used to add more cookies instead of replacing the former one which it
should've. Nusu <nus at intergorj.ro> brought me an URL that made this
painfully visible...
Troy (15 August 1999)
- Brought new .spec files as well as a patch for configure.in that lets the
configure script find the openssl files better, even when the include
files are in /usr/include/openssl
Version 5.10
Daniel (13 August 1999)
- SSL_CTX_set_default_passwd_cb() has been modified in the 0.9.4 version of
OpenSSL. Now why couldn't they simply add a *new* function instead of
modifying the parameters of an already existing function? This way, we get
a compiler warning if compiling with 0.9.4 but not with earlier. So, I had
to come up with a #if construction that deals with this...
- Made curl output the SSL version number get displayed properly with 0.9.4.
Troy (12 August 1999)
- Added MingW32 (GCC-2.95) support under Win32. The INSTALL file was also
a bit rearranged.
Daniel (12 August 1999)
- I had to copy a good <arpa/telnet.h> include file into the curl source
tree to enable the silly win32 systems to compile. The distribution rights
allows us to do that as long as the file remains unmodified.
- I corrected a few minor things that made the compiler complain when
-Wall -pedantic was used.
- I'm moving the official curl web page to http://curl.haxx.nu. I think it
will make it easier to remember as it is a lot shorter and less cryptic.
The old one still works and shows the same info.
Daniel (11 August 1999)
- Albert Chin-A-Young mailed me another correction for NROFF in the
configure.in that is supposed to be better for IRIX users.
Daniel (10 August 1999)
- Albert Chin-A-Young helped me with some stupid Makefile things, as well as
some fiddling with the getdate.c stuff that he had problems with under
HP-UX v10. getdate.y will now be compiled into getdate.c if the appropriate
yacc or bison is found by the configure script. Since this is slightly new,
we need to test the output getdate.c with win32 systems to make sure it
still compiles there.
Daniel (5 August 1999)
- I've just setup a new mailing list with the intention to keep discussions
around libcurl development in it. I mainly expect it to be for thoughts and
brainstorming around a "next generation" library, rather than nitpicking
about the current implementation or details in the current libcurl.
To join our happy bunch of future-looking geeks, enter 'subscribe
<address>' in the body of a mail and send it to
libcurl-request@listserv.fts.frontec.se. Curl bug reports, the usual curl
talk and everything else should still be kept in this mailing list. I've
started to archive this mailing list and have put the libcurl web page at
www.fts.frontec.se/~dast/libcurl/.
- Stefan Kanthak contacted me regarding a few problems in the configure
script which he discovered when trying to make curl compile and build under
Siemens SINIX-Z V5.42B2004!
- Marcus Klein very accurately informed me that src/version.h was not present
in the CVS repository. Oh, how silly...
- Linus Nielsen rewrote the telnet:// part and now curl offers limited telnet
support. If you run curl like 'curl telnet://host' you'll get all output on
the screen and curl will read input from stdin. You'll be able to login and
run commands etc, but since the output is buffered, expect to get a little
weird output.
This is still in its infancy and it might get changed. We need your
feed-back and input in how this is best done.
WIN32 NOTE: I bet we'll get problems when trying to compile the current
lib/telnet.c on win32, but I think we can sort them out in time.
- David Sanderson reported that FORCE_ALLOCA_H or HAVE_ALLOCA_H must be
defined for getdate.c to compile properly on HP-UX 11.0. I updated the
configure script to check for alloca.h which should make it.
Daniel (4 August 1999)
- I finally got to understand Marcus Klein's ftp download resume problem,
which turns out to be due to different outputs from different ftp
servers. It makes ftp download resuming a little trickier, but I've made
some modifications I really believe will work for most ftp servers and I do
hope you report if you have problems with this!
- Added text about file transfer resuming to README.curl.
Daniel (2 August 1999)
- Applied a progress-bar patch from Lars J. Aas. It offers
a new styled progress bar enabled with -#/--progress-bar.
T. Yamada <tai at imasy.or.jp> (30 July 1999)
- It breaks with segfault when 1) curl is using .netrc to obtain
username/password (option '-n'), and 2) is automatically redirected to
another location (option '-L').
There is a small bug in lib/url.c (block starting from line 641), which
tries to take out username/password from user- supplied command-line
argument ('-u' option). This block is never executed on first attempt since
CONF_USERPWD bit isn't set at first, but curl later turns it on when it
checks for CONF_NETRC bit. So when curl tries to redo everything due to
redirection, it segfaults trying to access *data->userpwd.
Version 5.9.1
Daniel (30 July 1999)
- Steve Walch pointed out that there is a memory leak in the formdata
functions. I added a FormFree() function that is now used and supposed to
correct this flaw.
- Mark Wotton reported:
'curl -L https://www.cwa.com.au/' core dumps. I managed to cure this by
correcting the cleanup procedure. The bug seems to be gone with my OpenSSL
0.9.2b, although still occurs when I run the ~100 years old SSLeay 0.8.0. I
don't know whether it is curl or SSLeay that is to blame for that.
- Marcus Klein:
Reported an FTP upload resume bug that I really can't repeat nor understand.
I leave it here so that it won't be forgotten.
Daniel (29 July 1999)
- Costya Shulyupin suggested support for longer URLs when following Location:
and I could only agree and fix it!
- Leigh Purdie found a problem in the upload/POST department. It turned out
that http.c accidentaly cleared the pointer instead of the byte counter
when supposed to.
- Costya Shulyupin pointed out a problem with port numbers and Location:. If
you had a server at a non-standard port that redirected to an URL using a
standard port number, curl still used that first port number.
- Ralph Beckmann pointed out a problem when using both CONF_FOLLOWLOCATION
and CONF_FAILONERROR simultaneously. Since the CONF_FAILONERROR exits on
the 302-code that the follow location header outputs it will never show any
html on location: pages. I have now made it look for >=400 codes if
CONF_FOLLOWLOCATION is set.
- 'struct slist' is now renamed to 'struct curl_slist' (as suggested by Ralph
Beckmann).
- Joshua Swink and Rick Welykochy were the first to point out to me that the
latest OpenSSL package now have moved the standard include path. It is now
in /usr/local/ssl/include/openssl and I have now modified the --enable-ssl
option for the configure script to use that as the primary path, and I
leave the former path too to work with older packages of OpenSSL too.
Daniel (9 June 1999)
- I finally understood the IRIX problem and now it seem to compile on it!
I am gonna remove those #define strcasecmp() things once and for all now.
Daniel (4 June 1999)
- I adjusted the FTP reply 227 parser to make the PASV command work better
with more ftp servers. Appearantly the Roxen Challanger server replied
something curl 5.9 could deal with! :-( Reported by Ashley Reid-Montanaro
and Mark Butler brought a solution for it.
Daniel (26 May 1999)
- Rearranged. README is new, the old one is now README.curl and I added a
README.libcurl with text I got from Ralph Beckmann.
- I also updated the INSTALL text.
Daniel (25 May 1999)
- David Jonathan Lowsky correctly pointed out that curl didn't properly deal
with form posting where the variable shouldn't have any content, as in curl
-F "form=" www.site.com. It was now fixed.
Version 5.9
Daniel (22 May 1999)
- I've got a bug report from Aaron Scarisbrick in which he states he has some
problems with -L under FreeBSD 3.0. I have previously got another bug
report from Stefan Grether which points at an error with similar sympthoms
when using win32. I made the allocation of the new url string a bit faster
and different, don't know if it actually improves anything though...
Daniel (20 May 1999)
- Made the cookie parser deal with CRLF newlines too.
Daniel (19 May 1999)
- Download() didn't properly deal with failing return codes from the sread()
function. Adam Coyne found the problem in the win32 version, and Troy Engel
helped me out isolating it.
Daniel (16 May 1999)
- Richard Adams pointed out a bug I introduced in 5.8. --dump-header doesn't
work anymore! :-/ I fixed it now.
- After a suggestion by Joshua Swink I added -S / --show-error to force curl
to display the error message in case of an error, even if -s/--silent was
used.
Daniel (10 May 1999)
- I moved the stuff concerning HTTP, DICT and TELNET it their own source
files now. It is a beginning on my clean-up of the sources to make them
layer all those protocols better to enable more to be added easier in the
future!
- Leon Breedt sent me some files I've not put into the main curl
archive. They're for creating the Debian package thingie. He also sent me a
debian package that I've made available for download at the web page
Daniel (9 May 1999)
- Made it compile on cygwin too.
Troy Engel (7 May 1999)
- Brought a series of patches to allow curl to compile smoothly on MSVC++ 6
again!
Daniel (6 May 1999)
- I changed the #ifdef HAVE_STRFTIME placement for the -z code so that it
will be easier to discover systems that don't have that function and thus
can't use -z successfully. Made the strftime() get used if WIN32 is defined
too.
Version 5.8
Daniel (5 May 1999)
- I've had it with this autoconf/automake mess. It seems to work allright
for most people who don't have automake installed, but for those who have
there are problems all over.
I've got like five different bug reports on this only the last
week... Claudio Neves and Federico Bianchi and root <duggerj001 at
hawaii.rr.com> are some of them reporting this.
Currently, I have no really good fix since I want to use automake myself to
generate the Makefile.in files. I've found out that the @SHELL@-problems
can often be fixed by manually invoking 'automake' in the archive root
before you run ./configure... I've hacked my maketgz script now to fiddle
a bit with this and my tests seem to work better than before at least!
Daniel (4 May 1999)
- mkhelp.pl has been doing badly lately. I corrected a case problem in
the regexes.
- I've now remade the -o option to not touch the file unless it needs to.
I had to do this to make -z option really fine, since now you can make a
curl fetch and use a local copy's time when downloading to that file, as
in:
curl -z dump -o dump remote.site.com/file.html
This will only get the file if the remote one is newer than the local.
I'm aware that this alters previous behaviour a little. Some scripts out
there may depend on that the file is always touched...
- Corrected a bug in the SSLv2/v3 selection.
- Felix von Leitner requested that curl should be able to send
"If-Modified-Since" headers, which indeed is a fair idea. I implemented it
right away! Try -z <expression> where expression is a full GNU date
expression or a file name to get the date from!
Stephan Lagerholm (30 Apr 1999)
- Pointed out a problem with the src/Makefile for FreeBSD. The RM variable
isn't set and causes the make to fail.
Daniel (26 April 1999)
- Am I silly or what? Irving Wolfe pointed out to me that the curl version
number was not set properly. Hasn't been since 5.6. This was due to a bug
in my maketgz script!
David Eriksson (25 Apr 1999)
- Found a bug in cookies.c that made it crash at times.
Version 5.7.1
Doug Kaufman (23 Apr 1999)
- Brought two sunos 4 fixes. One of them being the hostip.c fix mentioned
below and the other one a correction in include/stdcheaders.h
- Added a paragraph about compiling with the US-version of openssl to the
INSTALL file.
Daniel
- New mailing list address. Info updated on the web page as well as in the
README file
Greg Onufer (20 Apr 1999)
- hostip.c didn't compile properly on SunOS 5.5.1.
It needs an #include <sys/types.h>
Version 5.7
Daniel (Apr 20 1999)
- Decided to upload a non-beta version right now!
- Made curl support any-length HTTP headers. The destination buffer is now
simply enlarged every time it turns out to be too small!
- Added the FAQ file to the archive. Still a bit smallish, but it is a
start.
Eric Thelin (15 Apr 1999)
- Made -D accept '-' instead of filename to write to stdout.
Version 5.6.3beta
Daniel (Apr 12 1999)
- Changed two #ifdef WIN32 to better #ifdef <errorcode> when connect()ing
in url.c and ftp.c. Makes cygwin32 deal with them better too. We should
try to get some decent win32-replacement there. Anyone?
- The old -3/--crlf option is now ONLY --crlf!
- I changed the "SSL fix" to a more lame one, but that doesn't remove as
much functionality. Now I've enabled the lib to select what SSL version it
should try first. Appearantly some older SSL-servers don't like when you
talk v3 with them so you need to be able to force curl to talk v2 from the
start. The fix dated April 6 and posted on the mailing list forced curl to
use v2 at all times using a modern OpenSSL version, but we don't really
want such a crippled solution.
- Marc Boucher sent me a patch that corrected a math error for the
"Curr.Speed" progress meter.
- Eric Thelin sent me a patch that enables '-K -' to read a config file from
stdin.
- I found out we didn't close the file properly before so I added it!
Daniel (Apr 9 1999)
- Yu Xin pointed out a problem with ftp download resume. It didn't work at
all! ;-O
Daniel (Apr 6 1999)
- Corrected the version string part generated for the SSL version.
- I found a way to make some other SSL page work with openssl 0.9.1+ that
previously didn't (ssleay 0.8.0 works with it though!). Trying to get
some real info from the OpenSSL guys to see how I should do to behave the
best way. SSLeay 0.8.0 shouldn't be that much in use anyway these days!
Version 5.6.2beta
Daniel (Apr 4 1999)
- Finally have curl more cookie "aware". Now read carefully. This is how
it works.
To make curl read cookies from an already existing file, in plain header-
format (like from the headers of a previous fetch) invoke curl with the
-b flag like:
curl -b file http://site/foo.html
Curl will then use all cookies it finds matching. The old style that sets
a single cookie with -b is still supported and is used if the string
following -b includes a '=' letter, as in "-b name=daniel".
To make curl read the cookies sent in combination with a location: (which
sites often do) point curl to read a non-existing file at first (i.e
to start with no existing cookies), like:
curl -b nowhere http://site/setcookieandrelocate.html
- Added a paragraph in the TODO file about the SSL problems recently
reported. Evidently, some kind of SSL-problem curl may need to address.
- Better "Location:" following.
Douglas E. Wegscheid (Tue, 30 Mar 1999)
- A subsecond display patch.
Daniel (Mar 14 1999)
- I've separated the version number of libcurl and curl now. To make
things a little easier, I decided to start the curl numbering from
5.6 and the former version number known as "curl" is now the one
set for libcurl.
- Removed the 'enable-no-pass' from configure, I doubt anyone wanted
that.
- Made lots of tiny adjustments to compile smoothly with cygwin under
win32. It's a killer for porting this to win32, bye bye VC++! ;-)
Compiles and builds out-of-the-box now. See the new wordings in
INSTALL for details.
- Beginning experiments with downloading multiple document from a http
server while remaining connected.
Version 5.6beta
Daniel (Mar 13 1999)
- Since I've changed so much, I thought I'd just go ahead and implement the
suggestion from Douglas E. Wegscheid. -D or --dump-header is now storing
HTTP headers separately in the specified file.
- Added new text to INSTALL on what to do to build this on win32 now.
- Aaargh. I had to take a step back and prefix the shared #include files
in the sources with "../include/" to please VC++...
Daniel (Mar 12 1999)
- Split the url.c source into many tiny sources for better readability
and smaller size.
Daniel (Mar 11 1999)
- Started to change stuff for a move to make libcurl and a more separate
curl application that uses the libcurl. Made the libcurl sources into
the new lib directory while the curl application will remain in src as
before. New makefiles, adjusted configure script and so.
libcurl.a built quickly and easily. I better make a better interface to
the lib functions though.
The new root dir include/ is supposed to contain the public information
about the new libcurl. It is a little ugly so far :-)
Daniel (Mar 1 1999)
- Todd Kaufmann sent me a good link to Netscape's cookie spec as well as the
info that RFC 2109 specifies how to use them. The link is now in the
README and the RFC in the RESOURCES.
Daniel (Feb 23 1999)
- Finally made configure accept --with-ssl to look for SSL libs and includes
in the "standard" place /usr/local/ssl...
Daniel (Feb 22 1999)
- Verified that curl linked fine with OpenSSL 0.9.1c which seems to be
the most recent.
Henri Gomez (Fri Feb 5 1999)
- Sent in an updated curl-ssl.spec. I still miss the script that builds an
RPM automatically...
Version 5.5.1
Mark Butler (27 Jan 1999)
- Corrected problems in Download().
Danitel Stenberg (25 Jan 1999)
- Jeremie Petit pointed out a few flaws in the source that prevented it from
compile warning free with the native compiler under Digital Unix v4.0d.
Version 5.5
Daniel Stenberg (15 Jan 1999)
- Added Bjorns small text to the README about the DICT protocol.
Daniel Stenberg (11 Jan 1999)
- <jswink at softcom.net> reported about the win32-versioin: "Doesn't use
ALL_PROXY environment variable". Turned out to be because of the static-
buffer nature of the win32 environment variable calls!
Bjorn Reese (10 Jan 1999)
- I have attached a simple addition for the DICT protocol (RFC 2229).
It performs dictionary lookups. The output still needs to be better
formatted.
To test it try (the exact format, and more examples are described in
the RFC)
dict://dict.org/m:hello
dict://dict.org/m:hello::soundex
Vicente Garcia (10 Jan 1999)
- Corrected the progress meter for files larger than 20MB.
Daniel Stenberg (7 Jan 1999)
- Corrected the -t and -T help texts. They claimed to be FTP only.
Version 5.4
Daniel Stenberg
(7 Jan 1999)
- Irving Wolfe reported that curl -s didn't always supress the progress
reporting. It was the form post that autoamtically always switched it on
again. This is now corrected!
(4 Jan 1999)
- Andreas Kostyrka suggested I'd add PUT and he helped me out to test it. If
you use -t or -T now on a http or https server, PUT will be used for file
upload.
I removed the former use of -T with HTTP. I doubt anyone ever really used
that.
(4 Jan 1999)
- Erik Jacobsen found a width bug in the mprintf() function. I corrected it
now.
(4 Jan 1999)
- As John V. Chow pointed out to me, curl accepted very limited URL sizes. It
should now accept path parts that are up to at least 4096 bytes.
- Somehow I screwed up when applying the AIX fix from Gilbert Ramirez, so
I redid that now.

Changelog for the c-ares project
Version 1.3.0 (August 29, 2004)
* August 21
- Alfredo Tupone provided a fix for the Windows code in get_iphlpapi_dns_info()
when getting the DNS server etc.
* June 19
- Added some checks for the addrinfo structure.
* June 2
- William Ahern:
Make UDP sockets non-blocking. I've confirmed that at least on Linux 2.4 a
read event can come back from poll() on a valid SOCK_DGRAM socket but
recv(2) will still block. This patch doesn't ignore EAGAIN in
read_udp_packets(), though maybe it should. (This patch was edited by Daniel
Stenberg and a new configure test was added (imported from curl's configure)
to properly detect what non-blocking socket approach to use.)
I'm not quite sure how this was happening, but I've been seeing PTR queries
which seem to return empty responses. At least, they were empty when calling
ares_expand_name() on the record. Here's a patch which guarantees to
NUL-terminate the expanded name. The old behavior failed to NUL-terminate if
len was 0, and this was causing strlen() to run past the end of the buffer
after calling ares_expand_name() and getting ARES_SUCCESS as the return
value. If q is not greater than *s then it's equal and *s is always
allocated with at least one byte.
* May 16
- Added ares_getnameinfo which mimics the getnameinfo API (another feature
that could use testing).
* May 14
- Added an inet_ntop function from BIND for systems that do not have it.
* April 9
- Made sortlist support IPv6 (this can probably use some testing).
- Made sortlist support CIDR matching for IPv4.
* April 8
- Added preliminary IPv6 support to ares_gethostbyname. Currently, sortlist
does not work with IPv6. Also provided an implementation of bitncmp from
BIND for systems that do not supply this function. This will be used to add
IPv6 support to sortlist.
- Made ares_gethostbyaddr support IPv6 by specifying AF_INET6 as the family.
The function can lookup IPv6 addresses both from files (/etc/hosts) and
DNS lookups.
* April 7
- Tupone Alfredo fixed includes of arpa/nameser_compat.h to build fine on Mac
OS X.
* April 5
- Dominick Meglio: Provided implementations of inet_net_pton and inet_pton
from BIND for systems that do not include these functions.
* March 11, 2005
- Dominick Meglio added ares_parse_aaaa_reply.c and did various
adjustments. The first little steps towards IPv6 support!
* November 7
- Fixed the VC project and makefile to use ares_cancel and ares_version
* October 24
- The released ares_version.h from 1.2.1 says 1.2.0 due to a maketgz flaw.
This is now fixed.
Version 1.2.1 (October 20, 2004)
* September 29
- Henrik Stoerner fix: got a report that Tru64 Unix (the unix from Digital
when they made Alpha's) uses /etc/svc.conf for the purpose fixed below for
other OSes. He made c-ares check for and understand it if present.
- Now c-ares will use local host name lookup _before_ DNS resolving by default
if nothing else is told.
* September 26
- Henrik Stoerner: found out that c-ares does not look at the /etc/host.conf
file to determine the sequence in which to search /etc/hosts and DNS. So on
systems where this order is defined by /etc/host.conf instead of a "lookup"
entry in /etc/resolv.conf, c-ares will always default to looking in DNS
first, and /etc/hosts second.
c-ares now looks at
1) resolv.conf (for the "lookup" line);
2) nsswitch.fon (for the "hosts:" line);
3) host.conf (for the "order" line).
First match wins.
- Dominick Meglio patched: C-ares on Windows assumed that the HOSTS file is
located in a static location. It assumed
C:\Windows\System32\Drivers\Etc. This is a poor assumption to make. In fact,
the location of the HOSTS file can be changed via a registry setting.
There is a key called DatabasePath which specifies the path to the HOSTS
file:
http://www.microsoft.com/technet/itsolutions/network/deploy/depovg/tcpip2k.mspx
The patch will make c-ares correctly consult the registry for the location
of this file.
* August 29
- Gisle Vanem fixed the MSVC build files.
* August 20
- Gisle Vanem made c-ares build and work with his Watt-32 TCP/IP stack.
* August 13
- Harshal Pradhan made a minor syntax change in ares_init.c to make it build
fine with MSVC 7.1
* July 24
- Made the lib get built static only if --enable-debug is used.
- Gisle Vanem fixed:
Basically in loops like handle_errors(), 'query->next' was assigned a local
variable and then query was referenced after the memory was freed by
next_server(). I've changed that so next_server() and end_query() returns
the next query. So callers should use this ret-value.
The next problem was that 'server->tcp_buffer_pos' had a random value at
entry to 1st recv() (luckily causing Winsock to return ENOBUFS).
I've also added a ares_writev() for Windows to streamline the code a bit
more.
* July 20
- Fixed a few variable return types for some system calls. Made configure
check for ssize_t to make it possible to use that when receiving the send()
error code. This is necessary to prevent compiler warnings on some systems.
- Made configure create config.h, and all source files now include setup.h that
might include the proper config.h (or a handicrafted alternative).
- Switched to 'ares_socket_t' type for sockets in ares, since Windows don't
use 'int' for that.
- automake-ified and libool-ified c-ares. Now it builds libcares as a shared
lib on most platforms if wanted. (This bloated the size of the release
archive with another 200K!)
- Makefile.am now uses Makefile.inc for the c sources, h headers and man
pages, to make it easier for other makefiles to use the exact same set of
files.
- Adjusted 'maketgz' to use the new automake magic when building distribution
archives.
- Anyone desires HTML and/or PDF versions of the man pages in the release
archives?
* July 3
- Günter Knauf made c-ares build and run on Novell Netware.
* July 1
- Gisle Vanem provided Makefile.dj to build with djgpp, added a few more djgpp
fixes and made ares not use 'errno' to provide further info on Windows.
* June 30
- Gisle Vanem made it build with djgpp and run fine with the Watt-32 stack.
* June 10
- Gisle Vanem's init patch for Windows:
The init_by_resolv_conf() function fetches the DNS-server(s)
from a series of registry branches.
This can be wrong in the case where DHCP has assigned nameservers, but the
user has overridden these servers with other prefered settings. Then it's
wrong to use the DHCPNAMESERVER setting in registry.
In the case of no global DHCP-assigned or fixed servers, but DNS server(s)
per adapter, one has to query the adapter branches. But how can c-ares know
which adapter is valid for use? AFAICS it can't. There could be one adapter
that is down (e.g. a VPN adapter).
So it's better to leave this to the IP Helper API (iphlapi) available in
Win-98/2000 and later. My patch falls-back to the old way if not available.
* June 8
- James Bursa fixed an init issue for RISC OS.
* May 11
- Nico Stappenbelt reported that when processing domain and search lines in
the resolv.conf file, the first entry encountered is processed and used as
the search list. According to the manual pages for both Linux, Solaris and
Tru64, the last entry of either a domain or a search field is used.
This is now adjusted in the code
Version 1.2.0 (April 13, 2004)
* April 2, 2004
- Updated various man pages to look nicer when converted to HTML on the web
site.
* April 1, 2004
- Dirk Manske provided a new function that is now named ares_cancel(). It is
used to cancel/cleanup a resolve/request made using ares functions on the
given ares channel. It does not destroy/kill the ares channel itself.
- Dominick Meglio cleaned up the formatting in several man pages.
* March 30, 2004
- Dominick Meglio's new ares_expand_string. A helper function when decoding
incoming DNS packages.
- Daniel Stenberg modified the Makefile.in to use a for loop for the man page
installation to improve overview and make it easier to add man pages.
Version 1.1.0 (March 11, 2004)
* March 9, 2004
- Gisle Vanem improved build on Windows.
* February 25, 2004
- Dan Fandrich found a flaw in the Feb 22 fix.
- Added better configure --enable-debug logic (taken from the curl configure
script). Added acinclude.m4 to the tarball.
* February 23, 2004
- Removed ares_free_errmem(), the function, the file and the man page. It was
not used and it did nothing.
- Fixed a lot of code that wasn't "64bit clean" and thus caused a lot of
compiler warnings on picky compilers.
* February 22, 2004
- Dominick Meglio made ares init support multiple name servers in the
NameServer key on Windows.
* February 16, 2004
- Modified ares_private.h to include libcurl's memory debug header if
CURLDEBUG is set. This makes all the ares-functions supervised properly by
the curl test suite. This also forced me to add inclusion of the
ares_private.h header in a few more files that are using some kind of
memory-related resources.
- Made the makefile only build ahost and adig if 'make demos' is used.
* February 10, 2004
- Dirk Manske made ares_version.h installed with 'make install'
* February 4, 2004
- ares_free_errmem() is subject for removal, it is simply present for future
purposes, and since we removed the extra parameter in strerror() it won't
be used by c-ares!
- configure --enable-debug now enables picky compiler options if gcc is used
- fixed several compiler warnings --enable-debug showed and Joerg Mueller-Tolk
reported
Version 1.0.0 (February 3, 2004)
* February 3, 2004
- now we produce the libcares.a library instead of the previous libares.a
since we are no longer compatible
* February 2, 2004
- ares_strerror() has one argument less. This is the first official
modification of the existing provided ares API.
* January 29, 2004
- Dirk Manske fixed how the socket is set non-blocking.
* January 4, 2004
- Dominick Meglio made the private gettimeofday() become ares_gettimeofday()
instead in order to not pollute the name space and risk colliding with
other libraries' versions of this function.
* October 24, 2003. Daniel Stenberg
Added ares_version().
Version 1.0-pre1 (8 October 2003)
- James Bursa made it run on RISC OS
- Dominick Meglio made it run fine on NT4
- Duncan Wilcox made it work fine on Mac OS X
- Daniel Stenberg adjusted the windows port
- liren at vivisimo.com made the initial windows port
* Imported the sources from ares 1.1.1

# 2.Update the version information only immediately before a public release of
# your software. More frequent updates are unnecessary, and only guarantee

#
# 3.If the library source code has changed at all since the last update, then
# increment revision (c:r+1:a)
#
# 4.If any interfaces have been added, removed, or changed since the last
# update, increment current, and set revision to 0. (c+1:r=0:a)

# 5.If any interfaces have been added since the last public release, then

Major changes since:
* see the CHANGES file
Major changes in release 1.1.1:
* ares should now compile as C++ code (no longer uses reserved word
"class").
* Added SRV support to adig test program.
* Fixed a few error handling bugs in query processing.
Major changes in release 1.1.0:
* Added ares_free_string() function so that memory can be freed in the
same layer as it is allocated, a desirable feature in some
environments.
* A few of the ares_dns.h macros are fixed to use the proper bitwise
operator.
* Fixed a couple of fenceposts fixed in ares_expand_name()'s
bounds-checking.
* In process_timeouts(), extract query->next before calling
next_server() and possibly freeing the query structure.
* Casted arguments to ctype macros casted to unsigned char, since not
all char values are valid inputs to those macros according to ANSI.

This is c-ares, a forked version of the original ares. The original ares
README follows below, the c-ares specific details are in README.cares
====================================================================
This is ares, an asynchronous resolver library. It is intended for
applications which need to perform DNS queries without blocking, or
need to perform multiple DNS queries in parallel. The primary
examples of such applications are servers which communicate with
multiple clients and programs with graphical user interfaces.
This library implementation is not especially portable to crufty old
systems like SunOS 4. It assumes a compiler which can handle ANSI C
syntax, a system malloc which properly handles realloc(NULL, foo) and
free(NULL), and a reasonably up-to-date <arpa/nameser.h>.
I have attempted to preserve the externally visible behavior of the
BIND resolver in nearly all respects. The API of the library is, of
course, very different from the synchronous BIND API; instead of
invoking a function like res_send() and getting a return value back
indicating the number of bytes in the response, you invoke a function
like ares_send() and give it a callback function to invoke when the
response arrives. You then have to select() on the file descriptors
indicated by ares_fds(), with a timeout given by ares_timeout(). You
call ares_process() when select() returns.
Some features are missing from the current version of ares, relative
to the BIND resolver:
* There is no IPV6 support.
* There is no hostname verification.
* There is no logging of unexpected events.
* There is no debugging-oriented logging.
* There is no YP support.
libares requires an ANSI compiler to compile and use. To build the
library, just run "./configure" and "make". To install it, run "make
install". Run "./configure --help" to see a list of options you can
provide to configure to change how the library builds. libares has no
data files, so you can move the include file and library around freely
without leaving behind any dependencies on old paths. Building the
library will also build the "adig" program, a little toy for trying
out the library. It doesn't get installed.
libares is distributed at athena-dist.mit.edu:pub/ATHENA/ares. Please
send bug reports and comments to ghudson@mit.edu.

c-ares
======
This package is based on ares 1.1.1 (written by Greg Hudson). I decided to
fork and release a separate project since the ares author didn't want the
improvements that were vital for our use of it.
This package is dubbed 'c-ares' since I (Daniel Stenberg) wanted this for use
within the curl project (hence the letter C) and it makes a nice pun. Also,
c-ares is not API compatible with ares: a new name makes that more obvious to
the public.
The full source code is available in the 'c-ares' release archives, and in the
'ares' subdir of the curl CVS source repostitory.
If you find bugs, correct flaws, have questions or have comments in general in
regard to c-ares (or by all means the original ares too), get in touch with us
on the c-ares mailing list: http://cool.haxx.se/mailman/listinfo/c-ares
c-ares is of course distributed under the same MIT-style license as the
original ares.
You'll find all c-ares details and news here:

.TH ARES_EXPAND_NAME 3 "23 July 1998"
.SH NAME
ares_expand_name \- Expand a DNS-encoded domain name
.SH SYNOPSIS
.nf
.B #include <ares.h>
.PP
.B int ares_expand_name(const unsigned char *\fIencoded\fP,
.B const unsigned char *\fIabuf\fP, int \fIalen\fP, char **\fIs\fP,
.B int *\fIenclen\fP)
.fi
.SH DESCRIPTION
The
.B ares_expand_name
function converts a DNS-encoded domain name to a dot-separated C
string. The argument
.I encoded
gives the beginning of the encoded domain name, and the arguments
.I abuf
and
.I alen
give the containing message buffer (necessary for the processing of
indirection pointers within the encoded domain name). The result is
placed in a NUL-terminated allocated buffer, a pointer to which is
stored in the variable pointed to by
.IR s .
The length of the encoded name is stored in the variable pointed to by
.I enclen
so that the caller can advance past the encoded domain name to read
further data in the message.
.SH RETURN VALUES
.B ares_expand_name
can return any of the following values:
.TP 15
.B ARES_SUCCESS
Expansion of the encoded name succeeded.
.TP 15
.B ARES_EBADNAME
The encoded domain name was malformed and could not be expanded.
.TP 15
.B ARES_ENOMEM
Memory was exhausted.

* pointer gives an offset from the beginning of the containing
* message with more labels to decode. Indirection can happen an

.PP
.B int ares_fds(ares_channel \fIchannel\fP, fd_set *\fIread_fds\fP,
.B fd_set *\fIwrite_fds\fP)
.fi
.SH DESCRIPTION
The
.B ares_fds
function retrieves the set of file descriptors which the calling
application should select on for reading and writing for the
processing of name service queries pending on the name service channel
identified by
.IR channel .
File descriptors will be set in the file descriptor sets pointed to by
.I read_fds
and
.I write_fds
as appropriate. File descriptors already set in
.I read_fds
and
.I write_fds
will remain set; initialization of the file descriptor sets
(using
.BR FD_ZERO )
is the responsibility of the caller.
.SH RETURN VALUES
.B ares_fds
returns one greater than the number of the highest socket set in either
.I read_fds
or
.IR write_fds .
If no queries are active,
.B ares_fds
will return 0.

.TH ARES_FREE_HOSTENT 3 "23 July 1998"
.SH NAME
ares_free_hostent \- Free host structure allocated by ares functions
.SH SYNOPSIS
.nf
.B #include <ares.h>
.PP
.B void ares_free_hostent(struct hostent *\fIhost\fP)
.fi
.SH DESCRIPTION
The
.I ares_free_hostent
function frees a
.B struct hostent
allocated by one of the functions \fIares_parse_a_reply(3)\fP,
\fIares_parse_aaaa_reply(3)\fP, or \fIares_parse_ptr_reply(3)\fP.
.SH NOTES
It is not necessary (and is not correct) to free the host structure passed to
the callback functions for \fIares_gethostbyname(3)\fP or
\fIares_gethostbyaddr(3)\fP. The ares library will automatically free such
host structures when the callback returns.

.TH ARES_GETHOSTBYADDR 3 "24 July 1998"
.SH NAME
ares_gethostbyaddr \- Initiate a host query by address
.SH SYNOPSIS
.nf
.B #include <ares.h>
.PP
.B typedef void (*ares_host_callback)(void *\fIarg\fP, int \fIstatus\fP,
.B struct hostent *\fIhostent\fP)
.PP
.B void ares_gethostbyaddr(ares_channel \fIchannel\fP, const void *\fIaddr\fP,
.B int \fIaddrlen\fP, int \fIfamily\fP, ares_host_callback \fIcallback\fP,
.B void *\fIarg\fP)
.fi
.SH DESCRIPTION
The
.B ares_gethostbyaddr
function initiates a host query by address on the name service channel
identified by
.IR channel .
The parameters
.I addr
and
.I addrlen
give the address as a series of bytes, and
.I family
gives the type of address. When the query is complete or has failed, the ares
library will invoke \fIcallback\fP. Completion or failure of the query may
happen immediately, or may happen during a later call to
\fIares_process(3)\fP, \fIares_destroy(3)\fP or \fIares_cancel(3)\fP.
.PP
The callback argument
.I arg
is copied from the
.B ares_gethostbyaddr
argument
.IR arg .
The callback argument
.I status
indicates whether the query succeeded and, if not, how it failed. It
may have any of the following values:
.TP 19
.B ARES_SUCCESS
The host lookup completed successfully.
.TP 19
.B ARES_ENOTIMP
The ares library does not know how to look up addresses of type
.IR family .
.TP 19
.B ARES_ENOTFOUND
The address
.I addr
was not found.
.TP 19
.B ARES_ENOMEM
Memory was exhausted.
.TP 19
.B ARES_EDESTRUCTION
The name service channel
.I channel
is being destroyed; the query will not be completed.
.PP
On successful completion of the query, the callback argument
.I hostent
points to a
.B struct hostent
containing the name of the host returned by the query. The callback
need not and should not attempt to free the memory pointed to by
.IR hostent ;
the ares library will free it when the callback returns. If the query
did not complete successfully,
.I hostent
will be
.BR NULL .

.TH ARES_GETHOSTBYNAME 3 "25 July 1998"
.SH NAME
ares_gethostbyname \- Initiate a host query by name
.SH SYNOPSIS
.nf
.B #include <ares.h>
.PP
.B typedef void (*ares_host_callback)(void *\fIarg\fP, int \fIstatus\fP,
.B struct hostent *\fIhostent\fP)
.PP
.B void ares_gethostbyname(ares_channel \fIchannel\fP, const char *\fIname\fP,
.B int \fIfamily\fP, ares_host_callback \fIcallback\fP, void *\fIarg\fP)
.fi
.SH DESCRIPTION
The
.B ares_gethostbyname
function initiates a host query by name on the name service channel
identified by
.IR channel .
The parameter
.I name
gives the hostname as a NUL-terminated C string, and
.I family
gives the desired type of address for the resulting host entry. When the
query is complete or has failed, the ares library will invoke \fIcallback\fP.
Completion or failure of the query may happen immediately, or may happen
during a later call to \fIares_process(3)\fP, \fIares_destroy(3)\fP or
\fIares_cancel(3)\fP.
.PP
The callback argument
.I arg
is copied from the
.B ares_gethostbyname
argument
.IR arg .
The callback argument
.I status
indicates whether the query succeeded and, if not, how it failed. It
may have any of the following values:
.TP 19
.B ARES_SUCCESS
The host lookup completed successfully.
.TP 19
.B ARES_ENOTIMP
The ares library does not know how to find addresses of type
.IR family .
.TP 19
.B ARES_EBADNAME
The hostname
.B name
is composed entirely of numbers and periods, but is not a valid
representation of an Internet address.
.TP 19
.B ARES_ENOTFOUND
The address
.I addr
was not found.
.TP 19
.B ARES_ENOMEM
Memory was exhausted.
.TP 19
.B ARES_EDESTRUCTION
The name service channel
.I channel
is being destroyed; the query will not be completed.
.PP
On successful completion of the query, the callback argument
.I hostent
points to a
.B struct hostent
containing the name of the host returned by the query. The callback
need not and should not attempt to free the memory pointed to by
.IR hostent ;
the ares library will free it when the callback returns. If the query
did not complete successfully,
.I hostent
will be
.BR NULL .

.TH ARES_GETNAMEINFO 3 "16 May 2005"
.SH NAME
ares_getnameinfo \- Address-to-nodename translation in protocol-independent manner
.SH SYNOPSIS
.nf
.B #include <ares.h>
.PP
.B typedef void (*ares_nameinfo_callback)(void *\fIarg\fP, int \fIstatus\fP,
.B char *\fInode\fP, char *\fIservice\fP)
.PP
.B void ares_getnameinfo(ares_channel \fIchannel\fP, const struct sockaddr *\fIsa\fP,
.B socklen_t \fIsalen\fP, int \fIflags\fP, ares_nameinfo_callback \fIcallback\fP,
.B void *\fIarg\fP)
.fi
.SH DESCRIPTION
The
.B ares_getnameinfo
function is defined for protocol-independent address translation. The function
is a combination of \fIares_gethostbyaddr(3)\fP and \fIgetservbyport(3)\fP. The function will
translate the address either by executing a host query on the name service channel
identified by
.IR channel
or it will attempt to resolve it locally if possible.
The parameters
.I sa
and
.I len
give the address as a sockaddr structure, and
.I flags
gives the options that the function will use. Valid flags are listed below:
.TP 19
.B ARES_NI_NOFQDN
Only the nodename portion of the FQDN is returned for local hosts.
.TP 19
.B ARES_NI_NUMERICHOST
The numeric form of the hostname is returned rather than the name.
.TP 19
.B ARES_NI_NAMEREQD
An error is returned if the hostname cannot be found in the DNS.
.TP 19
.B ARES_NI_NUMERICSERV
The numeric form of the service is returned rather than the name.
.TP 19
.B ARES_NI_TCP
The service name is to be looked up for the TCP protocol.
.TP 19
.B ARES_NI_UDP
The service name is to be looked up for the UDP protocol.
.TP 19
.B ARES_NI_SCTP
The service name is to be looked up for the SCTP protocol.
.TP 19
.B ARES_NI_DCCP
The service name is to be looked up for the DCCP protocol.
.TP 19
.B ARES_NI_NUMERICSCOPE
The numeric form of the scope ID is returned rather than the name.
.TP 19
.B ARES_NI_LOOKUPHOST
A hostname lookup is being requested.
.TP 19
.B ARES_NI_LOOKUPSERVICE
A service name lookup is being requested.
.PP
When the query
is complete or has
failed, the ares library will invoke \fIcallback\fP. Completion or failure of
the query may happen immediately, or may happen during a later call to
\fIares_process(3)\fP, \fIares_destroy(3)\fP or \fIares_cancel(3)\fP.
.PP
The callback argument
.I arg
is copied from the
.B ares_getnameinfo
argument
.IR arg .
The callback argument
.I status
indicates whether the query succeeded and, if not, how it failed. It
may have any of the following values:
.TP 19
.B ARES_SUCCESS
The host lookup completed successfully.
.TP 19
.B ARES_ENOTIMP
The ares library does not know how to look up addresses of type
.IR family .
.TP 19
.B ARES_ENOTFOUND
The address
.I addr
was not found.
.TP 19
.B ARES_ENOMEM
Memory was exhausted.
.TP 19
.B ARES_EDESTRUCTION
The name service channel
.I channel
is being destroyed; the query will not be completed.
.TP 19
.B ARES_EBADFLAGS
The
.I flags
parameter contains an illegal value.
.PP
On successful completion of the query, the callback argument
.I node
contains a string representing the hostname (assuming
.B ARES_NI_LOOKUPHOST
was specified). Additionally,
.I service
contains a string representing the service name (assuming
.B ARES_NI_LOOKUPSERVICE
was specified).
If the query did not complete successfully, or one of the values
was not requested,
.I node
or
.I service
will be
.BR NULL .

.TH ARES_INIT 3 "7 December 2004"
.SH NAME
ares_init, ares_init_options \- Initialize a resolver channel
.SH SYNOPSIS
.nf
.B #include <ares.h>
.PP
.B int ares_init(ares_channel *\fIchannel\fP)
.B int ares_init_options(ares_channel *\fIchannel\fP,
.B struct ares_options *\fIoptions\fP, int \fIoptmask\fP)
.PP
.B cc file.c -lcares
.fi
.SH DESCRIPTION
The \fBares_init\fP function initializes a communications channel for name
service lookups. If it returns successfully, \fBares_init\fP will set the
variable pointed to by \fIchannel\fP to a handle used to identify the name
service channel. The caller should invoke
.BR ares_destroy (3)
on the handle when the channel is no longer needed.
.PP
The \fBares_init_options\fP function also initializes a name service channel,
with additional options useful for applications requiring more control over
name service configuration. The \fIoptmask\fP parameter specifies which fields
in the structure pointed to by \fIoptions\fP are set, as follows:
.TP 18
.B ARES_OPT_FLAGS
.B int \fIflags\fP;
.br
Flags controlling the behavior of the resolver. See below for a
description of possible flag values.
.TP 18
.B ARES_OPT_TIMEOUT
.B int \fItimeout\fP;
.br
The number of seconds each name server is given to respond to a query
on the first try. (After the first try, the timeout algorithm becomes
more complicated, but scales linearly with the value of
\fItimeout\fP.) The default is five seconds.
.TP 18
.B ARES_OPT_TRIES
.B int \fItries\fP;
.br
The number of tries the resolver will try contacting each name server
before giving up. The default is four tries.
.TP 18
.B ARES_OPT_NDOTS
.B int \fIndots\fP;
.br
The number of dots which must be present in a domain name for it to be
queried for "as is" prior to querying for it with the default domain
extensions appended. The default value is 1 unless set otherwise by
resolv.conf or the RES_OPTIONS environment variable.
.TP 18
.B ARES_OPT_PORT
.B unsigned short \fIport\fP;
.br
The port to use for queries (both TCP and UDP), in network byte order.
The default value is 53 (in network byte order), the standard name
service port.
.TP 18
.B ARES_OPT_SERVERS
.B struct in_addr *\fIservers\fP;
.br
.B int \fInservers\fP;
.br
The list of servers to contact, instead of the servers specified in
resolv.conf or the local named.
.TP 18
.B ARES_OPT_DOMAINS
.B char **\fIdomains\fP;
.br
.B int \fIndomains\fP;
.br
The domains to search, instead of the domains specified in resolv.conf
or the domain derived from the kernel hostname variable.
.TP 18
.B ARES_OPT_LOOKUPS
.B char *\fIlookups\fP;
.br
The lookups to perform for host queries.
.I lookups
should be set to a string of the characters "b" or "f", where "b"
indicates a DNS lookup and "f" indicates a lookup in the hosts file.
.PP
The
.I flags
field should be the bitwise or of some subset of the following values:
.TP 23
.B ARES_FLAG_USEVC
Always use TCP queries (the "virtual circuit") instead of UDP
queries. Normally, TCP is only used if a UDP query yields a truncated
result.
.TP 23
.B ARES_FLAG_PRIMARY
Only query the first server in the list of servers to query.
.TP 23
.B ARES_FLAG_IGNTC
If a truncated response to a UDP query is received, do not fall back
to TCP; simply continue on with the truncated response.
.TP 23
.B ARES_FLAG_NORECURSE
Do not set the "recursion desired" bit on outgoing queries, so that the name
server being contacted will not try to fetch the answer from other servers if
it doesn't know the answer locally. Be aware that ares will not do the
recursion for you. Recursion must be handled by the application calling ares
if \fIARES_FLAG_NORECURSE\fP is set.
.TP 23
.B ARES_FLAG_STAYOPEN
Do not close communciations sockets when the number of active queries
drops to zero.
.TP 23
.B ARES_FLAG_NOSEARCH
Do not use the default search domains; only query hostnames as-is or
as aliases.
.TP 23
.B ARES_FLAG_NOALIASES
Do not honor the HOSTALIASES environment variable, which normally
specifies a file of hostname translations.
.TP 23
.B ARES_FLAG_NOCHECKRESP
Do not discard responses with the SERVFAIL, NOTIMP, or REFUSED
response code or responses whose questions don't match the questions
in the request. Primarily useful for writing clients which might be
used to test or debug name servers.
.SH RETURN VALUES
.I ares_init
or
.I ares_init_options
can return any of the following values:
.TP 14
.B ARES_SUCCESS
Initialization succeeded.
.TP 14
.B ARES_EFILE
A configuration file could not be read.
.TP 14
.B ARES_ENOMEM
The process's available memory was exhausted.

.TH ARES_MKQUERY 3 "4 January 2000"
.SH NAME
ares_mkquery \- Compose a single-question DNS query buffer
.SH SYNOPSIS
.nf
.B #include <ares.h>
.PP
.B int ares_mkquery(const char *\fIname\fP, int \fIdnsclass\fP, int \fItype\fP,
.B unsigned short \fIid\fP, int \fIrd\fP, char **\fIbuf\fP,
.B int *\fIbuflen\fP)
.fi
.SH DESCRIPTION
The
.B ares_mkquery
function composes a DNS query with a single question.
The parameter
.I name
gives the query name as a NUL-terminated C string of period-separated
labels optionally ending with a period; periods and backslashes within
a label must be escaped with a backlash. The parameters
.I dnsclass
and
.I type
give the class and type of the query using the values defined in
.BR <arpa/nameser.h> .
The parameter
.I id
gives a 16-bit identifier for the query. The parameter
.I rd
should be nonzero if recursion is desired, zero if not. The query
will be placed in an allocated buffer, a pointer to which will be
stored in the variable pointed to by
.IR buf ,
and the length of which will be stored in the variable pointed to by
.IR buflen .
It is the caller's responsibility to free this buffer using
\fIares_free_string(3)\fP when it is no longer needed.
.SH RETURN VALUES
.B ares_mkquery
can return any of the following values:
.TP 15
.B ARES_SUCCESS
Construction of the DNS query succeeded.
.TP 15
.B ARES_EBADNAME
The query name
.I name
could not be encoded as a domain name, either because it contained a
zero-length label or because it contained a label of more than 63
characters.
.TP 15
.B ARES_ENOMEM
Memory was exhausted.

.TH ARES_PARSE_PTR_REPLY 3 "25 July 1998"
.SH NAME
ares_parse_ptr_reply \- Parse a reply to a DNS query of type PTR into a hostent
.SH SYNOPSIS
.nf
.B #include <ares.h>
.PP
.B int ares_parse_ptr_reply(const unsigned char *\fIabuf\fP, int \fIalen\fP,
.B const void *\fIaddr\fP, int \fIaddrlen\fP, int \fIfamily\fP,
.B struct hostent **\fIhost\fP);
.fi
.SH DESCRIPTION
The
.B ares_parse_ptr_reply
function parses the response to a query of type PTR into a
.BR "struct hostent" .
The parameters
.I abuf
and
.I alen
give the contents of the response. The parameters
.IR addr ,
.IR addrlen ,
and
.I family
specify which address was queried for; they are not used to verify the
response, merely used to fill in the address of the
.BR "struct hostent" .
The resulting
.B struct hostent
is stored in allocated memory and a pointer to it stored into the
variable pointed to by
.IR host .
It is the caller's responsibility to free the resulting host structure
using
.BR ares_free_hostent (3)
when it is no longer needed.
.SH RETURN VALUES
.B ares_parse_ptr_reply
can return any of the following values:
.TP 15
.B ARES_SUCCESS
The response was successfully parsed.
.TP 15
.B ARES_EBADRESP
The response was malformatted.
.TP 15
.B ARES_ENODATA
The response did not contain an answer to the query.
.TP 15
.B ARES_ENOMEM
Memory was exhausted.
.SH SEE ALSO
.BR ares_gethostbyaddr (3),
.BR ares_free_hostent (3)

.TH ARES_PROCESS 3 "25 July 1998"
.SH NAME
ares_process \- Process events for name resolution
.SH SYNOPSIS
.nf
.B #include <ares.h>
.PP
.B void ares_process(ares_channel \fIchannel\fP, fd_set *\fIread_fds\fP,
.B fd_set *\fIwrite_fds\fP)
.fi
.SH DESCRIPTION
The
.B ares_process
function handles input/output events and timeouts associated with
queries pending on the name service channel identified by
.IR channel .
The file descriptor sets pointed to by
.I read_fds
and
.I write_fds
should have file descriptors set in them according to whether the file
descriptors specified by \fIares_fds(3)\fP are ready for reading and writing.
(The easiest way to determine this information is to invoke
.B select
with a timeout no greater than the timeout given by \fIares_timeout(3)\fP ).
.PP
The
.B ares_process
function will invoke callbacks for pending queries if they complete
successfully or fail.
.SS EXAMPLE
The following code fragment waits for all pending queries on a channel
to complete:
.PP
.RS
.nf
int nfds, count;
fd_set readers, writers;
struct timeval tv, *tvp;
while (1)
{
FD_ZERO(&readers);
FD_ZERO(&writers);
nfds = ares_fds(channel, &readers, &writers);
if (nfds == 0)
break;
tvp = ares_timeout(channel, NULL, &tv);
count = select(nfds, &readers, &writers, NULL, tvp);
ares_process(channel, &readers, &writers);
}

.TH ARES_QUERY 3 "24 July 1998"
.SH NAME
ares_query \- Initiate a single-question DNS query
.SH SYNOPSIS
.nf
.B #include <ares.h>
.PP
.B typedef void (*ares_callback)(void *\fIarg\fP, int \fIstatus\fP,
.B unsigned char *\fIabuf\fP, int \fIalen\fP)
.PP
.B void ares_query(ares_channel \fIchannel\fP, const char *\fIname\fP,
.B int \fIdnsclass\fP, int \fItype\fP, ares_callback \fIcallback\fP,
.B void *\fIarg\fP)
.fi
.SH DESCRIPTION
The
.B ares_query
function initiates a single-question DNS query on the name service
channel identified by
.IR channel .
The parameter
.I name
gives the query name as a NUL-terminated C string of period-separated
labels optionally ending with a period; periods and backslashes within
a label must be escaped with a backslash. The parameters
.I dnsclass
and
.I type
give the class and type of the query using the values defined in
.BR <arpa/nameser.h> .
When the query is complete or has failed, the ares library will invoke
.IR callback .
Completion or failure of the query may happen immediately, or may
happen during a later call to
.BR ares_process (3)
or
.BR ares_destroy (3).
.PP
The callback argument
.I arg
is copied from the
.B ares_query
argument
.IR arg .
The callback argument
.I status
indicates whether the query succeeded and, if not, how it failed. It
may have any of the following values:
.TP 19
.B ARES_SUCCESS
The query completed successfully.
.TP 19
.B ARES_ENODATA
The query completed but contains no answers.
.TP 19
.B ARES_EFORMERR
The query completed but the server claims that the query was
malformatted.
.TP 19
.B ARES_ESERVFAIL
The query completed but the server claims to have experienced a
failure. (This code can only occur if the
.B ARES_FLAG_NOCHECKRESP
flag was specified at channel initialization time; otherwise, such
responses are ignored at the
.BR ares_send (3)
level.)
.TP 19
.B ARES_ENOTFOUND
The query completed but the queried-for domain name was not found.
.TP 19
.B ARES_ENOTIMP
The query completed but the server does not implement the operation
requested by the query. (This code can only occur if the
.B ARES_FLAG_NOCHECKRESP
flag was specified at channel initialization time; otherwise, such
responses are ignored at the
.BR ares_send (3)
level.)
.TP 19
.B ARES_EREFUSED
The query completed but the server refused the query. (This code can
only occur if the
.B ARES_FLAG_NOCHECKRESP
flag was specified at channel initialization time; otherwise, such
responses are ignored at the
.BR ares_send (3)
level.)
.TP 19
.B ARES_EBADNAME
The query name
.I name
could not be encoded as a domain name, either because it contained a
zero-length label or because it contained a label of more than 63
characters.
.TP 19
.B ARES_ETIMEOUT
No name servers responded within the timeout period.
.TP 19
.B ARES_ECONNREFUSED
No name servers could be contacted.
.TP 19
.B ARES_ENOMEM
Memory was exhausted.
.TP 19
.B ARES_EDESTRUCTION
The name service channel
.I channel
is being destroyed; the query will not be completed.
.PP
If the query completed (even if there was something wrong with it, as
indicated by some of the above error codes), the callback argument
.I abuf
points to a result buffer of length
.IR alen .
If the query did not complete,
.I abuf
will be NULL and
.I alen
will be 0.

.TH ARES_SEARCH 3 "24 July 1998"
.SH NAME
ares_search \- Initiate a DNS query with domain search
.SH SYNOPSIS
.nf
.B #include <ares.h>
.PP
.B typedef void (*ares_callback)(void *\fIarg\fP, int \fIstatus\fP,
.B unsigned char *\fIabuf\fP, int \fIalen\fP)
.PP
.B void ares_search(ares_channel \fIchannel\fP, const char *\fIname\fP,
.B int \fIdnsclass\fP, int \fItype\fP, ares_callback \fIcallback\fP,
.B void *\fIarg\fP)
.fi
.SH DESCRIPTION
The
.B ares_search
function initiates a series of single-question DNS queries on the name
service channel identified by
.IR channel ,
using the channel's search domains as well as a host alias file given
by the HOSTALIAS environment variable. The parameter
.I name
gives the alias name or the base of the query name as a NUL-terminated
C string of period-separated labels; if it ends with a period, the
channel's search domains will not be used. Periods and backslashes
within a label must be escaped with a backslash. The parameters
.I dnsclass
and
.I type
give the class and type of the query using the values defined in
.BR <arpa/nameser.h> .
When the query sequence is complete or has failed, the ares library
will invoke
.IR callback .
Completion or failure of the query sequence may happen immediately, or
may happen during a later call to
.BR ares_process (3)
or
.BR ares_destroy (3).
.PP
The callback argument
.I arg
is copied from the
.B ares_search
argument
.IR arg .
The callback argument
.I status
indicates whether the query sequence ended with a successful query
and, if not, how the query sequence failed. It may have any of the
following values:
.TP 19
.B ARES_SUCCESS
A query completed successfully.
.TP 19
.B ARES_ENODATA
No query completed successfully; when the query was tried without a
search domain appended, a response was returned with no answers.
.TP 19
.B ARES_EFORMERR
A query completed but the server claimed that the query was
malformatted.
.TP 19
.B ARES_ESERVFAIL
No query completed successfully; when the query was tried without a
search domain appended, the server claimed to have experienced a
failure. (This code can only occur if the
.B ARES_FLAG_NOCHECKRESP
flag was specified at channel initialization time; otherwise, such
responses are ignored at the
.BR ares_send (3)
level.)
.TP 19
.B ARES_ENOTFOUND
No query completed successfully; when the query was tried without a
search domain appended, the server reported that the queried-for
domain name was not found.
.TP 19
.B ARES_ENOTIMP
A query completed but the server does not implement the operation
requested by the query. (This code can only occur if the
.B ARES_FLAG_NOCHECKRESP
flag was specified at channel initialization time; otherwise, such
responses are ignored at the
.BR ares_send (3)
level.)
.TP 19
.B ARES_EREFUSED
A query completed but the server refused the query. (This code can
only occur returned if the
.B ARES_FLAG_NOCHECKRESP
flag was specified at channel initialization time; otherwise, such
responses are ignored at the
.BR ares_send (3)
level.)
.TP 19
.B ARES_TIMEOUT
No name servers responded to a query within the timeout period.
.TP 19
.B ARES_ECONNREFUSED
No name servers could be contacted.
.TP 19
.B ARES_ENOMEM
Memory was exhausted.
.TP 19
.B ARES_EDESTRUCTION
The name service channel
.I channel
is being destroyed; the query will not be completed.
.PP
If a query completed successfully, the callback argument
.I abuf
points to a result buffer of length
.IR alen .
If the query did not complete successfully,
.I abuf
will usually be NULL and
.I alen
will usually be 0, but in some cases an unsuccessful query result may
be placed in
.IR abuf .

.TH ARES_SEND 3 "25 July 1998"
.SH NAME
ares_send \- Initiate a DNS query
.SH SYNOPSIS
.nf
.B #include <ares.h>
.PP
.B typedef void (*ares_callback)(void *\fIarg\fP, int \fIstatus\fP,
.B unsigned char *\fIabuf\fP, int \fIalen\fP)
.PP
.B void ares_send(ares_channel \fIchannel\fP, const unsigned char *\fIqbuf\fP,
.B int \fIqlen\fP, ares_callback \fIcallback\fP, void *\fIarg\fP)
.fi
.SH DESCRIPTION
The
.B ares_send
function initiates a DNS query on the name service channel identified
by
.IR channel .
The parameters
.I qbuf
and
.I qlen
give the DNS query, which should already have been formatted according
to the DNS protocol. When the query is complete or has failed, the
ares library will invoke
.IR callback .
Completion or failure of the query may happen immediately, or may
happen during a later call to
.BR ares_process (3)
or
.BR ares_destroy (3).
.PP
The callback argument
.I arg
is copied from the
.B ares_send
argument
.IR arg .
The callback argument
.I status
indicates whether the query succeeded and, if not, how it failed. It
may have any of the following values:
.TP 19
.B ARES_SUCCESS
The query completed.
.TP 19
.B ARES_EBADQUERY
The query buffer was poorly formed (was not long enough for a DNS
header or was too long for TCP transmission).
.TP 19
.B ARES_ETIMEOUT
No name servers responded within the timeout period.
.TP 19
.B ARES_ECONNREFUSED
No name servers could be contacted.
.TP 19
.B ARES_ENOMEM
Memory was exhausted.
.TP 19
.B ARES_EDESTRUCTION
The name service channel
.I channel
is being destroyed; the query will not be completed.
.PP
If the query completed, the callback argument
.I abuf
points to a result buffer of length
.IR alen .
If the query did not complete,
.I abuf
will be NULL and
.I alen
will be 0.
.PP
Unless the flag
.B ARES_FLAG_NOCHECKRESP
was set at channel initialization time,
.B ares_send
will normally ignore responses whose questions do not match the
questions in
.IR qbuf ,
as well as responses with reply codes of
.BR SERVFAIL ,
.BR NOTIMP ,
and
.BR REFUSED .
Unlike other query functions in the ares library, however,
.B ares_send
does not inspect the header of the reply packet to determine the error
status, so a callback status of
.B ARES_SUCCESS
does not reflect as much about the response as for other query
functions.
