                                   Changelog
 
+Daniel (16 March 2006)
+- Tor Arntsen provided a RPM spec file for AIX Toolbox, that now is included
+  in the release archive.
+
+Daniel (14 March 2006)
+- David McCreedy fixed:
+
+  a bad SSL error message when OpenSSL certificates are verified fine.
+
+  a missing return code assignment in the FTP code
+
+Daniel (7 March 2006)
+- Markus Koetter filed debian bug report #355715 which identified a problem
+  with the multi interface and multi-part formposts. The fix from February
+  22nd could make the Curl_done() function get called twice on the same
+  connection and it was not designed for that and thus tried to call free() on
+  an already freed memory area!
+
+- Peter Heuchert made sure the CURLFTPSSL_CONTROL setting for CURLOPT_FTP_SSL
+  is used properly.
+
+Daniel (6 March 2006)
+- Lots of users on Windows have reported getting the "SSL: couldn't set
+  callback" error message so I've now made the setting of that callback not be
+  as critical as before. The function is only used for additional loggging/
+  trace anyway so a failure just means slightly less data. It should still be
+  able to proceed and connect fine to the server.
+
+Daniel (4 March 2006)
+- Thomas Klausner provided a patch written by Todd Vierling in bug report
+  #1442471 that fixes a build problem on Interix.
+
+Daniel (2 March 2006)
+- FTP upload without a file name part in the URL now causes
+  curl_easy_perform() to return CURLE_URL_MALFORMAT. Previously it allowed the
+  upload but named the file "(nil)" (without the quotes). Test case 524
+  verifies.
+
+- Added a check for getprotobyname in configure so that it'll be used, thanks
+  to Gisle Vanem's change the other day.
+
+Daniel (28 February 2006)
+- Dan Fandrich prevented curl from getting stuck in an endless loop in case we
+  are out of file handles very early in curl's code where it makes sure that
+  0, 1 and 2 aren't gonna be used by the lib for transfers.
+
+Daniel (27 February 2006)
+- Marty Kuhrt pointed out that there were two VMS-specific files missing in
+  the release archive.
+
+Version 7.15.2 (27 February 2006)
+
+Daniel (22 February 2006)
+- Lots of work and analysis by "xbx___" in bug #1431750
+  (http://curl.haxx.se/bug/view.cgi?id=1431750) helped me identify and fix two
+  different but related bugs:
+
+  1) Removing an easy handle from a multi handle before the transfer is done
+     could leave a connection in the connection cache for that handle that is
+     in a state that isn't suitable for re-use. A subsequent re-use could then
+     read from a NULL pointer and segfault.
+
+  2) When an easy handle was removed from the multi handle, there could be an
+     outstanding c-ares DNS name resolve request. When the response arrived,
+     it caused havoc since the connection struct it "belonged" to could've
+     been freed already.
+
+  Now Curl_done() is called when an easy handle is removed from a multi handle
+  pre-maturely (that is, before the transfer was complteted). Curl_done() also
+  makes sure to cancel all (if any) outstanding c-ares requests.
+
+Daniel (21 February 2006)
+- Peter Su added support for SOCKS4 proxies. Enable this by setting the proxy
+  type to the already provided type CURLPROXY_SOCKS4.
+
+  I added a --socks4 option that works like the current --socks5 option but
+  instead use the socks4 protocol.
+
+Daniel (20 February 2006)
+- Shmulik Regev fixed an issue with multi-pass authentication and compressed
+  content when libcurl didn't honor the internal ignorebody flag.
+
+Daniel (18 February 2006)
+- Ulf H<>rnhammar fixed a format string (printf style) problem in the Negotiate
+  code. It should however not be the cause of any troubles. He also fixed a
+  few similar problems in the HTTP test server code.
+
+Daniel (17 February 2006)
+- Shmulik Regev provided a fix for the DNS cache when using short life times,
+  as previously it could be holding on to old cached entries longer than
+  requested.
+
+Daniel (11 February 2006)
+- Karl Moerder added the CURLOPT_CONNECT_ONLY and CURLINFO_LASTSOCKET options
+  that an app can use to let libcurl only connect to a remote host and then
+  extract the socket from libcurl. libcurl will then not attempt to do any
+  transfer at all after the connect is done.
+
+- Kent Boortz improved the configure check for GnuTLS to properly set LIBS
+  instead of LDFLAGS.
+
+Daniel (8 February 2006)
+- Philippe Vaucher provided a brilliant piece of test code that show a problem
+  with re-used FTP connections. If the second request on the same connection
+  was set not to fetch a "body", libcurl could get confused and consider it an
+  attempt to use a dead connection and would go acting mighty strange.
+
+Daniel (2 February 2006)
+- Make --limit-rate [num] mean bytes. It used to be that but it broke in my
+  change done in November 2005.
+
+Daniel (30 January 2006)
+- Added CURLOPT_LOCALPORT and CURLOPT_LOCALPORTRANGE to libcurl. Set with the
+  curl tool with --local-port. Plain and simply set the range of ports to bind
+  the local end of connections to. Implemented on to popular demand.
+
+- Based on an error report by Philippe Vaucher, we no longer count a retried
+  connection setup as a follow-redirect. It turns out 1) this fails when a FTP
+  connection is re-setup and 2) it does make the max-redirs counter behave
+  wrong.
+
+Daniel (24 January 2006)
+- Michal Marek provided a patch for FTP that makes libcurl continue to try
+  PASV even after EPSV returned a positive response code, if libcurl failed to
+  connect to the port number the EPSV response said. Obviously some people are
+  going through protocol-sensitive firewalls (or similar) that don't
+  understand EPSV and then they don't allow the second connection unless PASV
+  was used. This also called for a minor fix of test case 238.
+
+Daniel (20 January 2006)
+- Duane Cathey was one of our friends who reported that curl -P [IP]
+  (CURLOPT_FTPPORT) didn't work for ipv6-enabed curls if the IP wasn't a
+  "native" IP while it works fine for ipv6-disabled builds!
+
+  In the process of fixing this, I removed the support for LPRT since I can't
+  think of many reasons to keep doing it and asking on the mailing list didn't
+  reveal anyone else that could either. The code that sends EPRT and PORT is
+  now also a lot simpler than before (IMHO).
+
+Daniel (19 January 2006)
+- Jon Turner pointed out that doing -P [hostname] (CURLOPT_FTPPORT) with curl
+  (built ipv4-only) didn't work.
+
+Daniel (18 January 2006)
+- As reported in bug #1408742 (http://curl.haxx.se/bug/view.cgi?id=1408742),
+  the configure script complained about a missing "missing" script if you ran
+  configure within a path whose name included one or more spaces. This is due
+  to a flaw in automake (1.9.6 and earlier). I've now worked around it by
+  including an "overloaded" version of the AM_MISSING_HAS_RUN script that'll
+  be used instead of the one automake ships with. This kludge needs to be
+  removed once we get an automake version with this problem corrected.
+  Possibly we'll then need to convert this into a kludge depending on what
+  automake version that is used and that is gonna be painful and I don't even
+  want to think about that now...!
+
+Daniel (17 January 2006)
+- David Shaw: Here is the latest libcurl.m4 autoconf tests. It is updated with
+  the latest features and protocols that libcurl supports and has a minor fix
+  to better deal with the obscure case where someone has more than one libcurl
+  installed at the same time.
+
+Daniel (16 January 2006)
+- David Shaw finally removed all traces of Gopher and we are now officially
+  not supporting it. It hasn't been functioning for years anyway, so this is
+  just finally stating what already was true. And a cleanup at the same time.
+
+- Bryan Henderson turned the 'initialized' variable for curl_global_init()
+  into a counter, and thus you can now do multiple curl_global_init() and you
+  are then supposed to do the same amount of calls to curl_global_cleanup().
+  Bryan has also updated the docs accordingly.
+
+Daniel (13 January 2006)
+- Andrew Benham fixed a race condition in the test suite that could cause the
+  test script to kill all processes in the current process group!
+
+Daniel (12 January 2006)
+- Michael Jahn:
+
+  Fixed FTP_SKIP_PASV_IP and FTP_USE_EPSV to "do right" when used on FTP thru
+  HTTP proxy.
+
+  Fixed PROXYTUNNEL to work fine when you do ftp through a proxy.  It would
+  previously overwrite internal memory and cause unpredicted behaviour!
+
+Daniel (11 January 2006)
+- I decided to document the "secret option" here now, as I've received *NO*
+  feedback at all on my mailing list requests from November 2005:
+
+  I'm looking for feedback and comments. I added some experimental code the
+  other day, that allows a libcurl user to select what method libcurl should
+  use to reach a file on a FTP(S) server.
+
+  This functionality is available in CVS code and in recent daily snapshots.
+
+  Let me explain...
+
+  The current name for the option is CURLOPT_FTP_FILEMETHOD (--ftp-method for
+  the command line tool) and you set it to a long (there are currenly no
+  defines for the argument values, just plain numericals). You can set three
+  different "methods" that do this:
+
+  1 multicwd - like today, curl will do a single CWD operation for each path
+           part in the given URL. For deep hierarchies this means very many
+           commands. This is how RFC1738 says it should be done. This is the
+           default.
+
+  2 nocwd - no CWD at all is done, curl will do SIZE, RETR, STOR etc and give
+           a full path to the server.
+
+  3 singlecwd - make one CWD with the full target directory and then operate
+            on the file "normally".
+
+  (With the command line tool you do --ftp-method [METHOD], where [METHOD] is
+  one of "multicwd", "nocwd" or "singlecwd".)
+
+  What feedback I'm interested in:
+
+  1 - Do they work at all? Do you find servers where one of these don't work?
+
+  2 - What would proper names for the option and its arguments be, if we
+      consider this feature good enough to get included and documented in
+      upcoming releases?
+
+  3 - Should we make libcurl able to "walk through" these options in case of
+      (path related) failures, or should it fail and let the user redo any
+      possible retries?
+
+  (This option is not documented in any man page just yet since I'm not sure
+  these names will be used or if the functionality will end up exactly like
+  this.  And for the same reasons we have no test cases for these yet.)
+
+Daniel (10 January 2006)
+- When using a bad path over FTP, as in when libcurl couldn't CWD into all
+  given subdirs, libcurl would still "remember" the full path as if it is the
+  current directory libcurl is in so that the next curl_easy_perform() would
+  get really confused if it tried the same path again - as it would not issue
+  any CWD commands at all, assuming it is already in the "proper" dir.
+
+  Starting now, a failed CWD command sets a flag that prevents the path to be
+  "remembered" after returning.
+
+Daniel (7 January 2006)
+- Michael Jahn fixed so that the second CONNECT when doing FTP over a HTTP
+  proxy actually used a new connection and not sent the second request on the
+  first socket!
+
+Daniel (6 January 2006)
+- Alexander Lazic made the buildconf run the buildconf in the ares dir if that
+  is present instead of trying to mimic that script in curl's buildconf
+  script.
+
+Daniel (3 January 2006)
+- Andres Garcia made the TFTP test server build with mingw.
+
+Daniel (16 December 2005)
+- Jean Jacques Drouin pointed out that you could only have a user name or
+  password of 127 bytes or less embedded in a URL, where actually the code
+  uses a 255 byte buffer for it! Modified now to use the full buffer size.
+
+Daniel (12 December 2005)
+- Dov Murik corrected the HTTP_ONLY define to disable the TFTP support properly
+
+Version 7.15.1 (7 December 2005)
+
+Daniel (6 December 2005)
+- Full text here: http://curl.haxx.se/docs/adv_20051207.html Pointed out by
+  Stefan Esser.
+
+  VULNERABILITY
+
+  libcurl's URL parser function can overflow a malloced buffer in two ways, if
+  given a too long URL.
+
+  These overflows happen if you
+ 
+  1 - pass in a URL with no protocol (like "http://") prefix, using no slash
+      and the string is 256 bytes or longer. This leads to a single zero byte
+      overflow of the malloced buffer.
+
+  2 - pass in a URL with only a question mark as separator (no slash) between
+      the host and the query part of the URL. This leads to a single zero byte
+      overflow of the malloced buffer.
+
+  Both overflows can be made with the same input string, leading to two single
+  zero byte overwrites.
+
+  The affected flaw cannot be triggered by a redirect, but the long URL must
+  be passed in "directly" to libcurl. It makes this a "local" problem. Of
+  course, lots of programs may still pass in user-provided URLs to libcurl
+  without doing much syntax checking of their own, allowing a user to exploit
+  this vulnerability.
+
+  There is no known exploit at the time of this writing.
+
+
+Daniel (2 December 2005)
+- Jamie Newton pointed out that libcurl's file:// code would close() a zero
+  file descriptor if given a non-existing file.
+
+Daniel (24 November 2005)
+- Doug Kaufman provided a set of patches to make curl build fine on DJGPP
+  again using configure.
+
+- Yang Tse provided a whole series of patches to clear up compiler warnings on
+  MSVC 6.
+
+Daniel (17 November 2005)
+- I extended a patch from David Shaw to make libcurl _always_ provide an error
+  string in the given error buffer to address the flaw mention on 21 sep 2005.
+
+Daniel (16 November 2005)
+- Applied Albert Chin's patch that makes the libcurl.pc pkgconfig file get
+  installed on 'make install' time.
+
+Daniel (14 November 2005)
+- Quagmire reported that he needed to raise a NTLM buffer for SSPI to work
+  properly for a case, and so we did. We raised it even for non-SSPI builds
+  but it should not do any harm. http://curl.haxx.se/bug/view.cgi?id=1356715
+
+- Jan Kunder's debian bug report
+  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=338680 identified a weird
+  error message for when you try to upload a file and the requested directory
+  doesn't exist on the target server.
+
+- Yang Tse fixed compiler warnings in lib/ssluse.c with OpenSSL 0.9.8 and in
+  lib/memdebug.h that showed up in his msvc builds.
+
+Daniel (13 November 2005)
+- Debian bug report 338681 by Jan Kunder: make curl better detect and report
+  bad limit-rate units:
+  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=338681 Now curl will return
+  error if a bad unit is used.
+
+- Thanks to this nice summary of poll() implementations:
+  http://www.greenend.org.uk/rjk/2001/06/poll.html and further tests by Eugene
+  Kotlyarov, we now know that cygwin's poll returns only POLLHUP on remote
+  connectin closure so we check for that case (too) and re-enable poll for
+  cygwin builds.
+
+Daniel (12 November 2005)
+- Eugene Kotlyarov found out that cygwin's poll() function isn't doing things
+  right: http://curl.haxx.se/mail/archive-2005-11/0045.html so we now disable
+  poll() and use select() on cygwin too (we already do the same choice on Mac
+  OS X)
+
+- Dima Barsky patched problem #1348930: the GnuTLS code completely ignored
+  client certificates! (http://curl.haxx.se/bug/view.cgi?id=1348930).
+
+Daniel (10 November 2005)
+- David Lang fixed IPv6 support for TFTP!
+
+- Introducing range stepping to the curl globbing support. Now you can specify
+  step counter by adding :[num] within the brackets when specifying a range:
+
+   [1-100:10]
+   [a-z:2]
+
+  If no step counter is set, it defaults to 1 as before:
+
+   [1-100]
+   [d-h]
+
+Daniel (8 November 2005)
+- Removed the use of AI_CANONNAME in the IPv6-enabled resolver functions since
+  we really have no use for reverse lookups of the address.
+
+  I truly hope these are the last reverse lookups we had lingering in the
+  code!
+
+- Dmitry Bartsevich discovered some issues in compatibilty of SSPI-enabled
+  version of libcurl with different Windows versions. Current version of
+  libcurl imports SSPI functions from secur32.dll. However, under Windows NT
+  4.0 these functions are located in security.dll, under Windows 9x - in
+  secur32.dll and Windows 2000 and XP contains both these DLLs (security.dll
+  just forwards calls to secur32.dll).
+
+  Dmitry's patch loads proper library dynamically depending on Windows
+  version. Function InitSecurityInterface() is used to obtain pointers to all
+  of SSPI function in one structure.
+
+Daniel (31 October 2005)
+- Vilmos Nebehaj improved libcurl's LDAP abilities:
+
+  The LDAP code in libcurl can't handle LDAP servers of LDAPv3 nor binary
+  attributes in LDAP objects. So, I made a quick patch to address these
+  problems.
+
+  The solution is simple: if we connect to an LDAP server, first try LDAPv3
+  (which is the preferred protocol as of now) and then fall back to LDAPv2.
+  In case of binary attributes, we first convert them to base64, just like the
+  openldap client does. It uses ldap_get_values_len() instead of
+  ldap_get_values() to be able to retrieve binary attributes correctly. I
+  defined the necessary LDAP macros in lib/ldap.c to be able to compile
+  libcurl without the presence of libldap
+
+Daniel (27 October 2005)
+- Nis Jorgensen filed bug report #1338648
+  (http://curl.haxx.se/bug/view.cgi?id=1338648) which really is more of a
+  feature request, but anyway. It pointed out that --max-redirs did not allow
+  it to be set to 0, which then would return an error code on the first
+  Location: found. Based on Nis' patch, now libcurl supports CURLOPT_MAXREDIRS
+  set to 0, or -1 for infinity. Added test case 274 to verify.
+
+- tommink[at]post.pl reported in bug report #1337723
+  (http://curl.haxx.se/bug/view.cgi?id=1337723) that curl could not upload
+  binary data from stdin on Windows if the data contained control-Z (hex 1a)
+  since that is treated as end-of-file when read in text mode. Gisle Vanem
+  pointed out the fix, and I made both -T and --data-binary take advantage of
+  it.
+
+- Jaz Fresh pointed out that if you used "-r [number]" as was wrongly described
+  in the man page, curl would send an invalid HTTP Range: header. The correct
+  way would be to use "-r [number]-" or even "-r -[number]". Starting now,
+  curl will warn if this is discovered, and automatically append a dash to the
+  range before passing it to libcurl.
+
+Daniel (25 October 2005)
+- Amol Pattekar reported a bug with great detail and a fine example in bug
+  #1326306 (http://curl.haxx.se/bug/view.cgi?id=1326306). When using the multi
+  interface and connecting to a host with multiple IP addresses, and one of
+  the addresses fails to connect (the server must exist and respond, just not
+  accept connections) libcurl leaks a socket descriptor. Thanks to the fine
+  report, I could find and fix this.
+
+Daniel (22 October 2005)
+- Dima Barsky reported a problem with GnuTLS-enabled libcurl in bug report
+  #1334338 (http://curl.haxx.se/bug/view.cgi?id=1334338). When reading an SSL
+  stream from a server and the server requests a "rehandshake", the current
+  code simply returns this as an error. I have no good way to test this, but
+  I've added a crude attempt of dealing with this situation slightly better -
+  it makes a blocking handshake if this happens. Done like this because fixing
+  this the "proper" way (that would handshake asynchronously) will require
+  quite some work and I really need a good way to test this to do such a
+  change.
+
+Daniel (21 October 2005)
+- "Ofer" reported a problem when libcurl re-used a connection and failed to do
+  it, it could then accidentally actually crash. Presumably, this concerns FTP
+  connections.  http://curl.haxx.se/bug/view.cgi?id=1330310
+
+- Temprimus improved the MSVC makefile so that the static debug SSL libs are
+  linked to the executable and not to the libcurld.lib
+  http://curl.haxx.se/bug/view.cgi?id=1326676
+
+- Bradford Bruce made the windows resolver code properly return
+  CURLE_COULDNT_RESOLVE_PROXY and CURLE_COULDNT_RESOLVE_HOST on resolving
+  errors (as documented).
+
+Daniel (20 October 2005)
+- Dave Dribin made libcurl understand and handle cases when the server
+  (wrongly) sends *two* WWW-Authenticate headers for Digest. While this should
+  never happen in a sane world, libcurl previously got into an infinite loop
+  when this occurred. Dave added test 273 to verify this.
+
+- Temprimus improved the MSVC makefile: "makes a build option available so if
+  you set rtlibcfg=static for the make, then it would build with /MT. The
+  default behaviour is /MD (the original)."
+  http://curl.haxx.se/bug/view.cgi?id=1326665
+
+Daniel (14 October 2005)
+- Reverted the LIBCURL_VERSION_NUM change from October 6. As Dave Dribin
+  reported, the define is used by the configure script and is assumed to use
+  the 0xYYXXZZ format. This made "curl-config --vernum" fail in the 7.15.0
+  release version.
+
+Version 7.15.0 (13 October 2005)
+
+Daniel (12 October 2005)
+- Michael Sutton of iDEFENSE reported and I fixed a securitfy flaw in the NTLM
+  code that would overflow a buffer if given a too long user name or domain
+  name. This would happen if you enable NTLM authentication and either
+
+  A - pass in a user name and domain name to libcurl that together are longer
+      than 192 bytes
+
+  B - allow (lib)curl to follow HTTP "redirects" (Location: and the
+      appropriate HTTP 30x response code) and the new URL contains a URL with
+      a user name and domain name that together are longer than 192 bytes
+
+  See http://curl.haxx.se/docs/security.html for further details and updates
+
+Daniel (5 October 2005)
+- Darryl House reported a problem with using -z to download files from FTP.
+  It turned out that if the given time stamp was exact the same as the remote
+  time stamp, the file would still wrongly be downloaded. Added test case 272
+  to verify.
+
+Daniel (4 October 2005)
+- Domenico Andreoli fixed a man page malformat and removed odd (0xa0) bytes
+  from the configure script.
+
+- Michael Wallner reported that the date parser had wrong offset stored for
+  the MEST and CEST time zones.
+
+Daniel (27 September 2005)
+- David Yan filed bug #1299181 (http://curl.haxx.se/bug/view.cgi?id=1299181)
+  that identified a silly problem with Content-Range: headers with the 'bytes'
+  keyword written in a different case than all lowercase! It would cause a
+  segfault!
+
+- TJ Saunders of the proftpd project identified and pointed out problems with
+  the modified FTPS negotiation change of August 19 2005. Thus, we revert the
+  change back to pre-7.14.1 status.
+
+Daniel (21 September 2005)
+- Fixed "cut off" sentence in the libcurl-tutorial man page:
+  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=329305
+
+- Clarified in the curl_easy_setopt man page what the default
+  CURLOPT_WRITEFUNCTION and CURLOPT_WRITEDATA mean:
+  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=329311
+
+- Clarified in the curl_easy_setopt man page that CURLOPT_ERRORBUFFER
+  sometimes doesn't fill in the buffer even though it is supposed to:
+  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=329313
+
+- When CURLE_URL_MALFORMAT is returned due to a missing URL, it now has an
+  error string set.
+
+Daniel (19 September 2005)
+- Dmitry Bartsevich made the SSPI support work on Windows 9x as well.
+
+Daniel (15 September 2005)
+- Added a TFTP server to the test suite and made the test suite capable of
+  using it.
+
+Daniel (7 September 2005)
+- Ben Madsen's detailed reports that funnily enough only occurred with certain
+  glibc versions turned out to be curl using an already closed file handle
+  during certain conditions (like when saving FTP server "headers").
+
+- Scott Davis helped me track down a problem in the test HTTP server that made
+  test case 56 wrongly fail at times. It turned out it was due to the server
+  finding the end of a chunked-encoded POST too early.
+
+Daniel (6 September 2005)
+- Now curl warns if an unknown variable is used in the -w/--writeout argument.
+
+Daniel (4 September 2005)
+- I applied Nicolas Fran<61>ois' man page patch he posted to the Debian bug
+  tracker. It corrected two lines that started with apostrophes, which isn't
+  legal nroff format. http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=326511
+
+- Added --ftp-skip-pasv-ip to the command line tool, that sets the new
+  CURLOPT_FTP_SKIP_PASV_IP option. It makes libcurl re-use the control
+  connection's IP address when setting up the data connection instead of
+  extractting the IP address from the PASV response. It has turned out this
+  feature is frequently needed by people to circumvent silly servers and silly
+  firewalls, especially when FTPS is used and the PASV command-response is
+  sent encrtyped.

+Daniel (1 September 2005)
+- John Kelly added TFTP support to libcurl. A bunch of new error codes was
+  added. TODO: add them to docs. add TFTP server to test suite. add TFTP to
+  list of protocols whereever those are mentioned.
+
+Version 7.14.1 (1 September 2005)
+
+Daniel (29 August 2005)
+- Kevin Lussier pointed out a problem with curllib.dsp and how to fix it.
+
+- Igor Polyakov fixed a rather nasty problem with the threaded name resolver
+  for Windows, that could lead to an Access Violation when the multi interface
+  was used due to an issue with how the resolver thread was and was not
+  terminated.
+
+- Simon Josefsson brought a patch that allows curl to get built to use GNU GSS
+  instead of MIT/Heimdal for GSS capabilities.
+
+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 to verify 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.
+  Ralph Mitchell reported.
+
+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
+  (http://curl.haxx.se/bug/view.cgi?id=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
+  (http://curl.haxx.se/bug/view.cgi?id=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
+  (http://curl.haxx.se/bug/view.cgi?id=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: http://curl.haxx.se/bug/view.cgi?id=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. http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=310948
+
+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
+  (http://curl.haxx.se/bug/view.cgi?id=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.

-
-55 - Add a function to the multi interface that gets file descriptors, as an
-     alternative to the curl_multi_fdset(). This is necessary to allow apps to
-     properly avoid the FD_SETSIZE problem.
-
-56 - Make curl_easy_perform() a wrapper-function that simply creates a multi
-     handle, adds the easy handle to it, runs curl_multi_perform() until the
-     transfer is done, then detach the easy handle, destroy the multi handle
-     and return the easy handle's return code. This will thus make everything
-     internally use and assume the multi interface. The select()-loop should
-     use the new function from (55).
-
-To get fixed in 7.16.0
-======================
-
-57 - Add an interface to libcurl for getting and setting cookies from an easy
-     handle. One idea: http://curl.haxx.se/mail/lib-2004-12/0195.html the
-     older idea: http://curl.haxx.se/dev/COOKIES. We need to settle on some
-     middle ground I guess.

   Changelog for the c-ares project
 
+* January 9, 2006
+
+- Alexander Lazic improved the getservbyport_r() configure check.
+
+* January 6, 2006
+
+- Alexander Lazic pointed out that the buildconf should use the ACLOCAL_FLAGS
+  variable for easier controlling what it does and how it runs.
+
+* January 5, 2006
+
+- James Bursa fixed c-ares to find the hosts file on RISC OS, and made it
+  build with newer gcc versions that no longer defines "riscos".
+
+* December 22
+
+- Daniel Stenberg added ares_getsock() that extracts the set of sockets to
+  wait for action on. Similar to ares_fds() but not restricted to using
+  select() for the waiting.
+
+* November 25
+
+- Yang Tse fixed some send() / recv() compiler warnings
+
+* September 18
+
+- Added constants that will be used by ares_getaddrinfo
+
+- Made ares_getnameinfo use the reentrant getservbyport (getservbyport_r) if it is
+  available to ensure it works properly in a threaded environment.
+
+* September 10
+
+- configure fix for detecting a member in the sockaddr_in6 struct which failed
+  on ipv6-enabled HP-UX 11.00
+
+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.

+.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 .

+.SH NAME
+ares_getsock \- get file descriptors to wait on
+.SH SYNOPSIS
+.nf
+.B #include <ares.h>
+.PP
+.B int ares_getsock(ares_channel \fIchannel\fP, int *\fIsocks\fP, 
+.B int \fInumsocks\fP);
+.fi
+.SH DESCRIPTION
+The
+.B ares_getsock
+function retrieves the set of file descriptors which the calling
+application should wait on for reading and/or 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 integer array pointed to by
+\fIsocks\fP.
+\fInumsocks\fP is the size of the given array in number of ints.
+
+This function can only return information about up to 16 sockets. If more are
+in use (however unlikely that is), they are simply not reported back.
+.SH RETURN VALUES
+\fBares_getsock\fP returns a bitmask for what actions to wait for on the
+different sockets. The ares.h header file provides these convenience macros to
+extract the information appropriately:
+
+.nf
+#define ARES_GETSOCK_MAXNUM 16 /* ares_getsock() can return info about
+                                  this many sockets */
+#define ARES_GETSOCK_READABLE(bits,num) (bits & (1<< (num)))
+#define ARES_GETSOCK_WRITABLE(bits,num) (bits & (1 << ((num) + \
+                                         ARES_GETSOCK_MAXNUM)))
+.fi
+.SH NOTES
+This function was added in c-ares 1.3.1
+.SH SEE ALSO
+.BR ares_timeout (3),
+.BR ares_fds (3),
+.BR ares_process (3)

+
+Condition
+
+ This document is written to describe the situation as it is right
+ now. libcurl 7.15.0 is currently the latest version available. Things may (or
+ perhaps will) of course change in the future.
+
+ This document reflects my view and understanding of these things. Please tell
+ me where and how you think I'm wrong, and I'll try to correct my mistakes.
+
+Background 
+
+ The Free Software Foundation has deemed the Original BSD license[1] to be
+ "incompatible"[2] with GPL[3]. I'd rather say it is the other way around, but
+ the point is the same: if you distribute a binary version of a GPL program,
+ it MUST NOT be linked with any Original BSD-licensed parts or
+ libraries. Doing so will violate the GPL license. For a long time, very many
+ GPL licensed programs have avoided this license mess by adding an
+ exception[8] to their license. And many others have just closed their eyes
+ for this problem.
+
+ libcurl is MIT-style[4] licensed - how on earth did this dilemma fall onto
+ our plates?
+
+ libcurl is only a little library. libcurl can be built to use OpenSSL for its
+ SSL/TLS capabilities. OpenSSL is basically Original BSD licensed[5].
+
+ If libcurl built to use OpenSSL is used by a GPL-licensed application and you
+ decide to distribute a binary version of it (Linux distros - for example -
+ tend to), you have a clash. GPL vs Original BSD.
+
+ This dilemma is not libcurl-specific nor is it specific to any particular
+ Linux distro. (This article mentions and refers to Debian several times, but
+ only because Debian seems to be the only Linux distro to have faced this
+ issue yet since no other distro is shipping libcurl built with two SSL
+ libraries.)
+
+Part of the Operating System
+
+ This would not be a problem if the used lib would be considered part of the
+ underlying operating system, as then the GPL license has an exception
+ clause[6] that allows applications to use such libs without having to be
+ allowed to distribute it or its sources. Possibly some distros will claim
+ that OpenSSL is part of their operating system.
+
+ Debian does however not take this stance and has officially(?) claimed that
+ OpenSSL is not a required part of the Debian operating system
+
+Debian-legal
+
+ In August 2004 I figured I should start pulling people's attention to this to
+ see if anyone has any bright ideas or if they would dismiss my worries based
+ on some elegant writing I had missed somewhere:
+
+ My post to debian-legal on August 12 2004:
+
+        http://lists.debian.org/debian-legal/2004/08/msg00279.html
+
+ Several people agreed then that this is a known and rather big problem, but
+ the following discussion didn't result in much.
+
+GnuTLS
+
+ With the release of libcurl 7.14.0 (May 2005), it can now get built to use
+ GnuTLS instead of OpenSSL. GnuTLS is a LGPL[7] licensed library that offers a
+ matching set of features as OpenSSL does. Now, you can build and distribute
+ an SSL capable libcurl without including any Original BSD licensed code.
+
+ I believe Debian is the first distro to provide libcurl/GnutTLS packages.
+
+GnuTLS vs OpenSSL
+
+ While these two libraries offer similar features, they are not equal. Both
+ libraries have features the other one lacks. libcurl does not (yet) offer a
+ standardized stable ABI if you decide to switch from using libcurl-openssl to
+ libcurl-gnutls or vice versa. The GnuTLS support is very recent in libcurl
+ and it has not been tested nor used very extensively, while the OpenSSL
+ equivalent code has been used and thus matured for more than seven (7) years.
+
+ In August 2005, the debian-devel mailing list discovered the license issue as
+ a GPL licensed application wanted SSL capabilities from libcurl and thus was
+ forced to use the GnuTLS powered libcurl. For a reason that is unknown to me,
+ the application authors didn't want to or was unable to add an exception to
+ their GPL license. Alas, the license problem hit the fan again.
+
+ GnuTLS
+   - LGPL licensened
+   - supports SRP
+   - lacks SSLv2 support
+   - lacks MD2 support (used by at least some CA certs)
+
+ OpenSSL
+   - Original BSD licensened
+   - lacks SRP
+   - supports SSLv2
+   - older and more widely used
+
+The Better License, Original BSD or LGPL?
+
+ It isn't obvious or without debate to any objective interested party that
+ either of these licenses are the "better" or even the "preferred" one in a
+ generic situation.
+
+ Instead, I think we should accept the fact that the SSL/TLS libraries and
+ their different licenses will fit different applications and their authors
+ differently depending on the applications' licenses and their general usage
+ pattern (considering how LGPL libraries for example can be burdensome for
+ embedded systems usage).
+
+ In Debian land, there seems to be a common opinion that LGPL is "maximally
+ compatible" with apps while Original BSD is not. Like this:
+
+        http://lists.debian.org/debian-devel/2005/09/msg01417.html
+
+More SSL Libraries
+
+ In libcurl, there's no stopping us here. There are at least a few more Open
+ Source/Free SSL/TLS libraries and we would very much like to support them as
+ well, to offer application authors an even wider scope of choice.
+
+Application Angle of this Problem
+
+ libcurl is built to use one SSL/TLS library. It uses a single fixed name (by
+ default), and applications are built/linked to use that single lib. Replacing
+ one libcurl instance with another one that uses the other SSL/TLS library
+ might break one or more applications (due to ABI differences and/or different
+ feature set). You want your application to use the libcurl it was built for.
+
+Project cURL Angle of this Problem
+
+ We distribute libcurl and everyone may build libcurl with either library. At
+ their choice. This problem is not directly a problem of ours. It merely
+ affects users - GPL application authors only - of our lib as it comes
+ included and delivered on some distros.
+
+ libcurl has different ABI when built with different SSL/TLS libraries due to
+ two reasons:
+
+ 1. No one has worked on fixing this. The mutex/lock callbacks should be set
+    with a generic libcurl function that should use the proper underlying
+    functions.
+
+ 2. The CURLOPT_SSL_CTX_FUNCTION option is not possible to "emulate" on GnuTLS
+    but simply requires OpenSSL.
+
+Distro Angle of this Problem
+
+ A distro can provide separate libcurls built with different SSL/TLS libraries
+ to work around this, but at least Debian seems to be very hostile against
+ such an approach, probably since it makes things like devel packages for the
+ different libs collide since they would provide the same include files and
+ man pages etc.
+
+Fixing the Only Problem
+
+ The only problem is thus for distributions that want to offer libcurl
+ versions built with more than one SSL/TLS library.
+
+ Debian is now (since mid September 2005) providing two different devel
+ packages, one for libcurl built with OpenSSL and one built with GnuTLS. They
+ use different .so names and can this both be installed in a single system
+ simultaneously. This has previously been said as a transitional system not
+ desired to keep in the long run.
+
+ Since multiple libcurl binaries using different names are ruled out, we need
+ to come up with a way to have one single libcurl that someone uses different
+ underlying libraries. The best(?) approach currently suggested involves this:
+
+ A new intermediate library (named lib2 so far in the discussions) with the
+ single purpose of providing libcurl with SSL/TLS capabilities. It would have
+ a unified API and ABI no matter what underlying library it would use.
+
+ There would be one lib2 binary provided for each supported SSL/TLS library.
+ For example: lib2-openssl, lib2-gnutls, lib2-yassl, lib2-matrixssl and
+ lib2-nossl. Yes, take note of the last one that provides the lib2 ABI but
+ that lacks the actual powers.
+
+ When libcurl is built and linked, it will be linked against a lib2 with the
+ set ABI.
+
+ When you link an app against libcurl, it would also need to provide one of
+ the (many) lib2 libs to decide what approach that fits the app. An app that
+ doesn't want SSL at all would still need to link with the lib2-nossl lib.
+
+ GPL apps can pick the lib2-gnutls, others may pick the lib2-openssl.
+
+ This concept works equally well both for shared and static libraries.
+
+ A positive side effect of this approach could be a more generic "de facto"
+ standard API for SSL/TLS libraries.
+
+When Will This Happen
+
+ Note again that this is not a problem in curl, it doesn't solve any actual
+ technical problems in our project. Don't hold your breath for this to happen
+ very soon (if at all) unless you step forward and contribute.
+
+ The suggestion that is outlined above is still only a suggestion. Feel free
+ to bring a better idea!
+
+ Also, to keep in mind: I don't want this new concept to have too much of an
+ impact on the existing code. Preferably it should be possible to build the
+ code like today (without the use of lib2), should you decide to ignore the
+ problems outlined in this document.
+
+ Update: Work on this has been initiated by Richard Atterer:

+
+  Libcurl Install and Use Issues
+  Awaiting an Answer for Win 32 Install 
+  res = curl_easy_perform(curl); Error
+  Makefile Issues
+  
+
+Having previously done a thorough review of what was available that met my
+requirements under GPL, I settled for Libcurl as the software of choice for
+many reasons not the least of which was the support.
+
+Background
+----------
+
+This quest started when I innocently tried to incorporate the libcurl library
+into my simple source code. I figured that a few easy steps would accomplish
+this without major headaches. I had no idea that I would be facing an almost
+insurmountable challenge.
+
+The main problem lies in two areas. First the bulk of support for libcurl
+exists for a Unix/linux command line environments. This is of little help when
+it comes to Windows O/S.
+
+Secondly the help that does exist for the Windows O/S focused around mingw
+thru a command line argument environment.
+
+You may ask "Why is this a problem?"
+
+I'm using a Windows O/S with DevCpp. For those of you who are unfamiliar with
+DevCpp, it is a window shell GUI that replaces the command line environment
+for gcc. A definite improvement that I am unwilling to give up. However using
+DevCpp presented its own set of issues. Inadvertently I also made some
+careless errors such as compiling the 7.14 version of Makefile with an older
+version of source code. Thanks to Dan Fandrich for picking this up.
+
+I did eventually with the help of Daniel, Phillipe and others manage to
+implement successfully (the only mingw available version)
+curl-7.13.0-win32-ssl-devel-mingw32 into the DevCpp environment. Only the
+dynamic libcurl.dll libcurldll.a libraries worked. The static library which I
+was interested in did not. Furthermore when I tried to implement one of the
+examples included with the curl package (get info.c) it caused the executable
+to crash. Tracing the bug I found it in the code and function res =
+curl_easy_perform(curl);.
+
+At this point I had to make a choice as to whether invest my limited
+time-energy resource to fixing the bug or to compile the new version
+available. After searching the archives I found a very similar or the same bug
+reported from version 7.12x on. Daniel did inform me that he thought that this
+bug had been fixed with the latest version. So I proceeded to compile the
+latest SSL version where I faced other challenges.
+
+In order to make this process unremarkable for others using the same
+environment I decided to document the process so that others will find it
+routine. It would be a shame if newbies could not implement this excellent
+package for their use.
+
+I would like to thank the many others in this forum and in the DevCpp forum
+for their help. Without your help I may either have given up or it would have
+taken me many times longer to achieve success.
+
+The Cookbook Approach
+---------------------
+
+This discussion will be confined to a SSL static library compilation and
+installation. Limited mention and comments will be inserted where appropriate
+to help with non-SSL, dynamic libraries and executables.
+
+
+   Using Makefile from DevCpp to compile Libcurl libraries
+
+Preamble
+--------
+
+Using the latest version release - curl-7.14.0.tar.gz. Curl source code is
+platform independent. This simply means that the source code can be compiled
+for any Operating System (Linux/Unix Windows etc. and variations of thereof).
+
+The first thing to note is that inside curl-7.14.0 you will find two folders
+lib and src. Both contain Makefile.m32 (required for win mingw library or exe
+compilation) files which are different. The main difference between these two
+folders and the makefiles is that the src folder contents are used to compile
+an executable file(curl.exe) while the lib folder contents are used to compile
+a static (libcurl.a) and dynamic (libcurl.dll & libcurldll.a) file that can be
+used to compile libcurl with your own source code so that one can use and
+access all libcurl functions.
+
+Before we start please make sure that DevCpp is installed properly. In
+particular make sure you have no spaces in the name of any of the directories
+and subdirectories where DevCpp is installed. Failure to comply with the
+install instructions may produce erratic behaviour in DevCpp. For further info
+check the following sites
+
+http://aditsu.freeunixhost.com/dev-cpp-faq.html
+http://sourceforge.net/forum/message.php?msg_id=3252213
+
+As I have mentioned before I will confine this to the SSL Library compilations
+but the process is very similar for compilation of the executable - curl.exe;
+just substitute the src folder makefile in its stead.
+
+First use a text processor Notepad, or your own favourite text processor. To
+engage your favourite text processor, select Makefile.m32 click once with your
+mouse on file icon; icon turns blue, press the shift key and right-click on
+mouse, menu appears select "Open with", select your favourite text processor.
+
+Next read the contents of Makefile.m32. It includes instructions on its use.
+
+Method I - DOS Command Line
+---------------------------
+ 
+Note - The only reason I have included this method is that Method II which is
+the preferred method for compiling does not allow for the setting of option
+switches (e.g. SSL = 1 or SSL =0). At least that's what they tell me at the
+Dev-Cpp forum.
+
+1 - Make a copy of (D:\Dev-Cpp\bin) bin folder and name it "bin Original"
+place it in the Dev-Cpp installed directory (D:\Dev-Cpp\ for this example)
+
+2 - Copy the entire contents of the LIB folder of curl-7.14.0.tar.gz or zip
+version into the bin folder above (D:\Dev-Cpp\bin). The reason being is that
+the make.exe file resides in this folder. Make.exe will use - Makefile.m32,
+Makefile.inc, and the source code included in the lib folder to compile the
+source code. There is a PATH issue with make.exe that remains unresolved at
+least for me. Unless the entire source code to be compiled is placed entirely
+within the directory of make.exe an error message will be generated - "file
+xxxx.yyy not available".
+
+3- Go to Dev-Cpp\bin and double click on make .exe. You will see a DOS window
+quickly pop up and close very quickly. Not to worry! Please do not skip this
+step.
+
+4- Click on the start button\Programs\MS-DOS Prompt.Once the DOS Window is up
+Type the disk drive letter (e.g. E: ) engage the enter button. The path should
+automatically take you to the directory of the make.exe file.
+
+5- To compile the source code simply type at the DOS prompt make -f
+Makefile.m32 as per instructions contained in the Makefile.m32 file (use any
+text processor to read instructions). I don't believe that this makefile
+allows for the option of non SSL. Ignore any warnings.
+
+6- Collect and make copies of libcurl.a, libcurl.dll, libcurldll.a and any *.o
+compilations you might need in another directory outside of the bin directory
+as you will need this files shortly to set up libcurl for use with
+Dev-cpp. For most apps *.o is not required. Later on we will show what to do
+with these files.
+
+7- You are finished but before closing we need to do cleanup - erase the bin
+folder and rename the "bin Original" folder created in step 1 to bin.
+
+Note to compile a curl executable the process is probably similar but instead
+of using the LIB folder contents use the SRC folder contents and Makefiles in
+curl-7.14.0.tar.gz. File directories relative placements must be respected for
+compiling to take place successfully. This may not be possible with the PATH
+problem that make.exe experiences. If anyone has solved this PATH issue and
+please make sure it actually works on Win 9x/2000/XP before letting me
+know. Then please let me or Daniel in on the solution so that it can be
+included with these instructions. Thanks.
+
+or
+
+Method II - Dev-Cpp GUI
+-----------------------
+
+1- Copy the entire contents of the LIB folder of curl-7.14.0.tar.gz or zip
+version into any folder outside of (Dev-Cpp\bin).
+
+2- Drop the File/New/click on Project.
+
+3- New Project Dialogue box appears. Double click on the Static Library.
+
+4- Create Project Dialogue box appears. Select the LIB folder location to
+place and locate your Project File Name. Placing the Project File Name
+elsewhere may cause problems (PATH issue problem again).
+
+5- Drop down the Project/Project Options. Project Options Dialogue box
+appears.
+
+6- Select the Makefile tab in the Project Options Dialogue Box. Check Box -
+Use Custom Makefile. Click on the Folder icon at the extreme right of the
+Check Box. Select Makefile.m32 in the folder wherever you have placed the
+contents of the LIB Folder. Press OK and close the Dialogue Box.
+
+7- Drop the Menu Project/Click on Add to Project. Open File Dialogue Box
+appears.  The Dialogue Box should open in the folder wherever you have placed
+the contents of the LIB Folder. If not go there.
+
+8- Select Crtl-A to select all files in the LIB folder. Click on open to add
+files and close box. Wait till all files are added. This may take 30 seconds
+or longer.
+
+9- Drop the Menu Execute/Click on Compile. 
+
+10- That's it.
+
+
+   The following steps must be completed if Curl is to work properly
+   =================================================================
+
+LIB folder inclusions (*.a placement)
+-------------------------------------
+
+1- Refer to Method I - DOS Command Line point # 6 Take libcurl.a, libcurldll.a
+and install it in the directory C( or whichever drive Dev is installed)
+:\Dev-Cpp\lib.
+
+
+Include Folder
+--------------
+
+1- Create a new folder by the name of curl (do not change the name curl to
+some other name as it will cause major issues) in the directory
+C:\Dev-Cpp\include.
+
+2- Copy the entire contents of the curl folder of curl-7.14.0.tar.gz or zip
+ version into the newly created curl directory - C:\Dev-Cpp\include\curl.
+
+Links To Include And Lib Folder
+-------------------------------
+
+1- Drop the Menu - Tools\Compiler Options\Directories\Libraries. Make sure
+that C( or whichever drive Dev is installed):\DEV-CPP\lib is included.
+
+2- Next select the Menu - Tools\Compiler Options\Directories\C Includes. Make
+sure that C:\DEV-CPP\include and C:\Dev-Cpp\include\curl are included.
+
+3- Next select the Menu - Tools\Compiler Options\Directories\C++
+Includes. Make sure that C:\DEV-CPP\include and C:\Dev-Cpp\include\curl are
+included.
+
+Linker Links
+------------
+
+1- Drop the Menu - Tools\Compiler Options\Directories\Compiler.
+
+2- Make sure that the box "Add these commands to the linker command line" is
+checked.
+
+3- Include in the white space immediately below the box referred in 2 -lcurl
+-lws2_32 -lwinmm.
+
+SSL Files
+---------
+
+1- Get the latest openSSL (as of time of this writing)
+openssl-0.9.7e-win32-bin.zip for the minimalist package of the openssl-0.9.7e
+binaries ported to MS Windows 95/98/NT/XP using the MingW32/GCC-3.1
+development environment. The file may be downloaded at
+http://curl.haxx.se/download/.
+
+2- Open the above zip file. You will find two files - SDL.dll,
+SDL_mixer.dll. Install them in the directory C:\WINDOWS\SYSTEM32 for Win 9x
+users and c:\winnt\system32 for NT-family users.
+
+Multithreading Files
+--------------------
+
+To be completed
+
+#define
+-------
+
+1- Make sure that your program includes the following - #define CURL_STATICLIB
+must be declared FIRST before any other define functions may be
+added. Otherwise you may experience link errors.
+
+2- Don't forget to include   #include "curl/curl.h".
+
+e.g.
+    #define CURL_STATICLIB 
+#include <windows.h>
+    #include "curl/curl.h"
+#include <fstream>
+#include <iostream>
+#include <vector>
+etc...
+
+
+Static or Dynamic Library
+-------------------------
+
+The above steps apply for the use by a static library. Should you choose to
+use a dynamic library you will be required to perform these additional steps.
+
+1- Refer to Method I - DOS Command Line point # 6. Install libcurl.dll in the
+directory C:\WINDOWS\SYSTEM32 for Win 9x users and c:\winnt\system32 for
+NT-family users.
+
+2- Refer to Linker Links point 3 - Replace -lcurl with -lcurldll.
+
+Voila you're done.
+
+The non-SSL static Library build may not be possible to use at least as of the
+time of this writing - v7.14. Check reference emails - Phillipe and I found it
+impossible to fully compile as certain files were missing for linking. No big
+loss as SSL is a major plus.
+
+Hope this Helps

 You can specify any amount of URLs on the command line. They will be fetched
 in a sequential manner in the specified order.
 
+Since curl 7.15.1 you can also specify step counter for the ranges, so that
+you can get every Nth number or letter:
+
+ http://www.numericals.com/file[1-100:10].txt
+ http://www.letters.com/file[a-z:2].txt
+
+If you specify URL without protocol:// prefix, curl will attempt to guess what
+protocol you might want. It will then default to HTTP but try other protocols
+based on often-used host name prefixes. For example, for host names starting
+with "ftp." curl will assume you want to speak FTP.
+
 Curl will attempt to re-use connections for multiple file transfers, so that
 getting many files from the same server will not do multiple connects /
 handshakes. This improves speed. Of course this is only done on files
 specified on a single command line and cannot be used between separate curl
 invokes.
+.SH "PROGRESS METER"
+curl normally displays a progress meter during operations, indicating amount
+of transfered data, transfer speeds and estimated time left etc.
+
+However, since curl displays data to the terminal by default, if you invoke
+curl to do an operation and it is about to write data to the terminal, it
+\fIdisables\fP the progress meter as otherwise it would mess up the output
+mixing progress meter and response data.
+
+If you want a progress meter for HTTP POST or PUT requests, you need to
+redirect the response output to a file, using shell redirect (>), -o [file] or
+similar.
+
+It is not the same case for FTP upload as that operation is not spitting out
+any response data to the terminal.
+
+If you prefer a progress "bar" instead of the regular meter, \fI-#\fP is your
+friend.

+ * This example code only builds as-is on Windows.
+ *
+ * Synchronising your computer clock via Internet time server usually relies
+ * on DAYTIME, TIME, or NTP protocols. These protocols provide good accurate
+ * time synchronisation but it does not work very well through a
+ * firewall/proxy. Some adjustment has to be made to the firewall/proxy for
+ * these protocols to work properly.
+ *
+ * There is an indirect method. Since most webserver provide server time in
+ * their HTTP header, therefore you could synchronise your computer clock
+ * using HTTP protocol which has no problem with firewall/proxy.
+ *
+ * For this software to work, you should take note of these items.
+ * 1. Your firewall/proxy must allow your computer to surf internet.
+ * 2. Webserver system time must in sync with the NTP time server,
+ *    or at least provide an accurate time keeping.
+ * 3. Webserver HTTP header does not provide the milliseconds units,
+ *    so there is no way to get very accurate time.
+ * 4. This software could only provide an accuracy of +- a few seconds,
+ *    as Round-Trip delay time is not taken into consideration.
+ *    Compensation of network, firewall/proxy delay cannot be simply divide
+ *    the Round-Trip delay time by half.
+ * 5. Win32 SetSystemTime() API will set your computer clock according to
+ *    GMT/UTC time. Therefore your computer timezone must be properly set.
+ * 6. Webserver data should not be cached by the proxy server. Some
+ *    webserver provide Cache-Control to prevent caching.
+ *
+ * References:
+ * http://tf.nist.gov/timefreq/service/its.htm
+ * http://tf.nist.gov/timefreq/service/firewall.htm
+ *
+ * Usage:
+ * This software will synchronise your computer clock only when you issue
+ * it with --synctime. By default, it only display the webserver's clock.

+.SH NAME
+curl_multi_setopt \- set options for a curl multi handle
+.SH SYNOPSIS
+#include <curl/curl.h>
+
+CURLMcode curl_multi_setopt(CURLM * multi_handle, CURLMoption option, param);
+.SH DESCRIPTION
+curl_multi_setopt() is used to tell a libcurl multi handle how to behave. By
+using the appropriate options to \fIcurl_multi_setopt\fP, you can change
+libcurl's behaviour when using that multi handle.  All options are set with
+the \fIoption\fP followed by the parameter \fIparam\fP. That parameter can be
+a \fBlong\fP, a \fBfunction pointer\fP, an \fBobject pointer\fP or a
+\fBcurl_off_t\fP type, depending on what the specific option expects. Read
+this manual carefully as bad input values may cause libcurl to behave badly!
+You can only set one option in each function call.
+
+.SH OPTIONS
+.IP CURLMOPT_SOCKETFUNCTION
+Pass a pointer to a function matching the curl_socket_callback prototype. The
+\fIcurl_multi_socket(3)\fP functions inform the application about updates in
+the socket (file descriptor) status by doing none, one or multiple calls to
+the curl_socket_callback given in the \fBparam\fP argument. They update the
+status with changes since the previous time a \fIcurl_multi_socket(3)\fP
+function was called. If the given callback pointer is NULL, no callback will
+be called. Set the callback's fourth argument with \fICURLMOPT_SOCKETDATA\fP.
+See \fIcurl_multi_socket(3)\fP for more callback details.
+.IP CURLMOPT_SOCKETDATA
+Pass a pointer to whatever you want passed to the curl_socket_callback's forth
+argument, the userp pointer. This is not used by libcurl but only passed-thru
+as-is. Set the callback pointer with \fICURLMOPT_SOCKETFUNCTION\fP.
+.SH RETURNS
+The standard CURLMcode for multi interface error codes. Note that it returns a
+CURLM_UNKNOWN_OPTION if you try setting an option that this version of libcurl
+doesn't know of.

+curl_multi_socket \- reads/writes available data

+
+CURLMcode curl_multi_socket(CURLM * multi_handle, curl_socket_t sockfd);
+
+CURLMcode curl_multi_socket_all(CURLM *multi_handle);
+.SH DESCRIPTION
+Alternative versions of \fIcurl_multi_perform()\fP that allows the application
+to pass in one of the file descriptors/sockets that have been detected to have
+\&"action" on them and let libcurl perform. This allows libcurl to not have to
+scan through all possible file descriptors to check for action. When the
+application has detected action on a socket handled by libcurl, it should call
+\fIcurl_multi_perform()\fP with the \fBsockfd\fP argument set to the socket
+with the action.
+
+These functions inform the application about updates in the socket (file
+descriptor) status by doing none, one or multiple calls to the
+curl_socket_callback given with the CURLMOPT_SOCKETFUNCTION option to
+\fIcurl_multi_setopt(3)\fP. They update the status with changes since the
+previous time this function was called.
+
+If you want to force libcurl to (re-)check all its internal sockets and
+transfers instead of just a single one, you call
+\fBcurl_multi_socket_all(3)\fP instead.
+
+An application should call \fBcurl_multi_timeout(3)\fP to figure out how long
+it should wait for socket actions \- at most \- before doing the timeout
+action: call the \fBcurl_multi_socket(3)\fP function with the \fBsockfd\fP
+argument set to CURL_SOCKET_TIMEOUT.
+
+The socket \fBcallback\fP function uses a prototype like this
+.nf
+
+     int curl_socket_callback(CURL *easy,      /* easy handle */
+                              curl_socket_t s, /* socket */
+                              int action,      /* see values below */
+                              void *userp);    /* "private" pointer */
+
+.fi
+The callback MUST return 0.
+
+The \fIaction\fP (third) argument to the callback has one of five values:
+.RS
+.IP "CURL_POLL_NONE (0)"
+register, not interested in readiness (yet)
+.IP "CURL_POLL_IN (1)"
+register, interested in read readiness
+.IP "CURL_POLL_OUT (2)"
+register, interested in write readiness
+.IP "CURL_POLL_INOUT (3)"
+register, interested in both read and write readiness
+.IP "CURL_POLL_REMOVE (4)"
+deregister
+.RE
+.SH "RETURN VALUE"
+CURLMcode type, general libcurl multi interface error code.
+
+If you receive \fICURLM_CALL_MULTI_PERFORM\fP, this basically means that you
+should call \fIcurl_multi_perform\fP again, before you wait for more actions
+on libcurl's sockets. You don't have to do it immediately, but the return code
+means that libcurl may have more data available to return or that there may be
+more data to send off before it is "satisfied".
+
+NOTE that this only returns errors etc regarding the whole multi stack. There
+might still have occurred problems on individual transfers even when this
+function returns OK.
+.SH "TYPICAL USAGE"
+1. Create a multi handle
+
+2. Set the socket callback with CURLMOPT_SOCKETFUNCTION
+
+3. Add easy handles
+
+4. Call curl_multi_socket_all() first once
+
+5. Setup a "collection" of sockets to supervise when your socket
+callback is called.
+
+6. Use curl_multi_timeout() to figure out how long to wait for action
+
+7. Wait for action on any of libcurl's sockets
+
+8, When action happens, call curl_multi_socket() for the socket(s) that got
+action.
+
+9. Go back to step 6.

+.SH SYNOPSIS

+
+CURLMcode curl_multi_timeout(CURLM *multi_handle, long *timeout);
+.SH DESCRIPTION
+
+An application using the libcurl multi interface should call
+\fBcurl_multi_timeout(3)\fP to figure out how long it should wait for socket
+actions \- at most \- before proceeding.
+
+Proceeding means either doing the socket-style timeout action: call the
+\fBcurl_multi_socket(3)\fP function with the \fBsockfd\fP argument set to
+CURL_SOCKET_TIMEOUT and the \fBeasy\fP argument set to CURL_EASY_TIMEOUT, or
+simply calling \fBcurl_multi_perform(3)\fP if you're using the simpler and
+older multi interface approach.
+
+The timeout value returned in the long \fBtimeout\fP points to, is in number
+of milliseconds at this very moment. If 0, it means you should proceed

+at all set.
