+
+Daniel (16 January 2002)
+- Mofied the main transfer loop and related stuff to deal with non-blocking
+  sockets in the upload section. While doing this, I've now separated the
+  connection oriented buffers to have one for downloads and one for uploads
+  (as two can happen simultaneously). I also shrunk the buffers to 20K
+  each. As we have a scratch buffer twice the size of the upload buffer, we
+  arrived at 80K for buffers compared with the previous 150K.
+
+- Added the --cc option to curl-config command as it enables so very cool
+  one-liners. Have a go a this one, building the simple.c example:
+
+        $ `curl-config --cc --cflags --libs` -o example simple.c
+
+Daniel (14 January 2002)
+- I made all socket reads (recv) handle EWOULDBLOCK. I hope nicely. Now we
+  only need to address all writes (send) too and then I'm ready for another
+  pre-release...
+
+- Stoned Elipot patched the in_addr_t configure test to make it work better on
+  more platforms.
+
+Daniel (9 January 2002)
+- Cris Bailiff found out that filling up curl's SSL session cache caused a
+  crash!
+
+- Posted the curl questionnaire on the web site. If you haven't posted your
+  opinions there yet, go there and do it now while it is still there:
+
+        http://curl.haxx.se/q/
+
+- Georg Horn quickly found out that the SSL reading no longer worked as
+  supposed since the switch to non-blocking sockets. I've made a quick patch
+  (for reading only) but we should improve it even further.
+
+Version 7.9.3-pre1
+
+Daniel (7 January 2002)
+- I made the 'bool' typedef use an "unsigned char". It makes it the same on
+  all platforms, no matter what the platform thinks the default format for
+  char is. This was noticed since we made a silly comparison involving such a
+  bool variable, and only one compiler/platform combination (on Debian Linux)
+  complained about it (that happened to have its char unsigned by default).
+
+- Bug report #495290 identified a cookie parsing problem that was corrected.
+  When a Set-Cookie: line is received without a trailing semicolon, libcurl
+  didn't read the last "name=value" pair of the line, leading to confusions...
+
+- Sterling committed his updated DNS cache code.
+
+- I worked with Georg Horn and comments from G<>tz Babin-Ebell and switched
+  curl's socket operations completely over to non-blocking for the entire
+  operation (previously we used non-blocking only for the connection phase).
+  We had to do this to make the SSL connection phase timeout properly without
+  the use of signals. A little extra code to deal with this was added.
+
+- T. Bharath pointed out a slightly obscure cookie engine flaw.
+
+- Pete Su pointed out that libcurl didn't treat HTTP code 204 as it should.
+  204-replies never provides a response-body. This resulted in bad persistant
+  behavior when 204 was received.
+
+Daniel (5 January 2002)
+- SM updated the VC++ library Makefiles for the new source files.
+
+Daniel (4 January 2002)
+- I discovered that we wrongly used inet_ntoa() (instead of inet_ntoa_r() in
+  two places in the source code). One happened with VERBOSE set on connects,
+  and the other when VERBOSE was on and krb4 over nat was used... I honestly
+  don't think anyone has suffered from these mistakes.
+
+- I replaced a lot of silly occurances of printf() to instead use the more
+  appropriate Curl_infof() or Curl_failf(). The krb4 and telnet code were
+  affected.
+
+- Philip Gladstone found a few more problems with 64-bit archs (the 64-bit
+  sparc on solaris 8).
+
+- After discussions on the libcurl list with Raoul Cridlig, I just made FTP
+  response lines get passed to the header callback if such a one is
+  registered. It'll make it possible for any application to get all the
+  responses an FTP server sends to libcurl.
+
+Daniel (3 January 2002)
+- Sterling Hughes brought a few buckets of code. Now, libcurl will
+  automatically cache DNS lookups and re-use the previous results first if any
+  such is available. It greatly improves speed when doing many repeated
+  operations to the same host.
+
+- As the test case uses --include and then --head, I had to modify src/main.c
+  to deal with this situation slightly better than previously. When done, we
+  have 100% good tests again in the main branch.
+
+Daniel (2 January 2002)
+- Made test case 25 run again in the multi-dev branch. But it seems that the
+  changes done on dec-20 made test case 104 cease to work (in both branches).
+
+- Philip Gladstone pointed out a few portability problems in the source code
+  that didn't compile on 64-bit sparcs using Sun's native compiler...
+
+Daniel (20 December 2001)
+- Bj<42>rn Stenberg caught an unpleasent (but hard-to-find) bug that could cause
+  libcurl to hang on transfers over proxy, when the proxy was specified with
+  an environment variable!
+
+- Added code to make ftp operations treat the NO_BODY and HEADERS options
+  better:
+
+   NO_BODY set TRUE and HEADERS set TRUE:
+    Return a set of headers with file info
+
+   NO_BODY set FALSE
+    Transfer data as usual, HEADERS is ignored
+
+   NO_BODY set TRUE and HEADERS set FALSE
+    Don't transfer any data, don't return any headers. Just perform the set
+    of FTP commands.
+
+Daniel (17 December 2001)
+- G<>tz Babin-Ebell dove into the dark dungeons of the OpenSSL ENGINE stuff and
+  made libcurl support it! This allows libcurl to do SSL connections with the
+  private key stored in external hardware.
+
+  To make this good, he had to add a bunch of new library options that'll be
+  useful to others as well:
+
+   CURLOPT_SSLCERTTYPE  set SSL cert type (PEM/DER)
+   CURLOPT_SSLKEY       set SSL private key (file)
+   CURLOPT_SSLKEYTYPE:  set SSL key type (PEM/DER/ENG)
+   CURLOPT_SSLKEYPASSWD: set the passphrase for your private key
+                          (CURLOPT_SSLCERTPASSWD is an alias)
+   CURLOPT_SSLENGINE:   set the name of the crypto engine
+                        (returns CURLE_SSL_ENGINE_NOTFOUND on error)
+   CURLOPT_SSLENGINE_DEFAULT: set the default engine
+
+  There are two new failure codes:
+
+   CURLE_SSL_ENGINE_NOTFOUND
+   CURLE_SSL_ENGINE_SETFAILED
+
+Daniel (14 December 2001)
+- We have "branched" the source-tree at a few places. Checkout the CVS sources
+  with the 'multi-dev' label to get the latest multi interface development
+  tree. The idea is to only branch affected files and to restrict the branch
+  to the v8 multi interface development only.
+
+  *NOTE* that if we get bug reports and patches etc, we might need to apply
+  them in both branches!
+
+  The multi-dev branch is what we are gonna use as main branch in the future
+  if it turns out successful. Thus, we must maintain both now in case we need
+  them. The current main branch will be used if we want to release a 7.9.3 or
+  perhaps a 7.10 release before version 8. Which is very likely.
+
+- Marcus Webster provided code for the new CURLFORM_CONTENTHEADER option for
+  curl_formadd(), that lets an application add a set of headers for that
+  particular part in a multipart/form-post. He also provided a section to the
+  man page that describes the new option.
+
+Daniel (11 December 2001)
+- Ben Greear made me aware of the fact that the Curl_failf() usage internally
+  was a bit sloppy with adding newlines or not to the error messages. Let's
+  once and for all say that they do not belong there!
+
+- When uploading files with -T to give a local file name, and you end the URL
+  with a slash to have the local file name used remote too, we now no longer
+  use the local directory as well. Only the file part of the -T file name
+  will be appended to the right of the slash in the URL.
+
+Daniel (7 December 2001)
+- Michal Bonino pointed out that Digital Unix doesn't have gmtime_r so the
+  link failed. Added a configure check and corrected source code.
+
+Version 7.9.2
+
+Daniel (5 December 2001)
+- Jon Travis found out that if you used libcurl and CURLOPT_UPLOAD and then
+  on the same handle used CURLOPT_HTTPGET it would still attempt to upload.
+  His suggested fix was perfect.
+
+Daniel (4 December 2001)
+- Incorporated more macos fixes and added four specific files in a new
+  subdirectory below src.
+
+Daniel (3 December 2001)
+- Eric Lavigne reported two problems:
+
+  First one in the curl_strnequal() function. I think this problem is rather
+  macos 9 specific, as most platform provides a function to use instead of the
+  one provided by libcurl.
+
+  A second, more important, was in the way we take care of FTP responses. The
+  code would read a large chunk of data and search for the end-of-response
+  line within that chunk. When found, it would just skip the rest of the
+  data. However, when the network connections are special, or perhaps the
+  server is, we could actually get more than one response in that chunk of
+  data so that when the next invoke to this function was done, the response
+  had already been read and thrown away. Now, we cache the data not used in
+  one call, as it could be useful in the subsequent call. Test case 126 was
+  added and the test ftp server modified, to exercise this particular case.
+
+Version 7.9.2-pre8
+
+Daniel (2 December 2001)
+- Bug report #487825 correctly identified a problem when using a proxy and
+  following a redirection from HTTP to HTTPS. libcurl then re-used the same
+  proxy connection but without doing a proper HTTPS request.
+
+- Fixed win32 compiling quirks.
+
+Version 7.9.2-pre7
+
+Daniel (30 November 2001)
+- Documented --disable-epsv and CURLOPT_FTP_USE_EPSV.
+
+Daniel (29 November 2001)
+- Added --disable-epsv as an option. When used, curl won't attempt to use the
+  EPSV command when doing passive FTP downloads. Wrote a test case for it.
+
+- Eric provided a few more fixes for building on Macs. He also pointed out
+  a flaw in the signal handler restoration code.
+
+Daniel (28 November 2001)
+- Fiddled with some Tru64 problems reported by Dimitris Sarris. They appeared
+  only when using VERBOSE ftp transfers. Do we use a too small buffer for
+  gethostbyaddr_r(), was the lack of using in_addr_t wrong or is it that the
+  hostent struct must be blanked before use? With Dimitris help and these
+  patches, the problems seem to be history.
+
+- CURLOPT_FTP_USE_EPSV was added and can be set to FALSE to prevent libcurl
+  from using the EPSV command before trying the normal PASV. Heikki Korpela
+  pointed out that some firewalls and similar don't like the EPSV so we must
+  be able to shut if off to work everywhere.
+
+- I added a configure check for 'in_addr_t' and made the ftp code use that to
+  receive the inet_addr() return code in. Works on Solaris and Linux at
+  least. The Linux man page for inet_addr() doesn't even mention in_addr_t...
+
+- Adjusted (almost) all FTP tests to the new command sequence.
+
+- FTP command sequence changes:
+
+  EPSV is now always attempted before PASV. It is the final touch to make IPv6
+  passive FTP downloads to work, but EPSV is not restricted to IPv6 but works
+  fine with IPv4 too on the servers that support it.
+
+  SIZE is now always issued before RETR. It makes curl know the actual
+  download size before the download takes place, as it makes it less important
+  to find the size sent in RETR responses. Many sites don't include the size
+  in there.
+
+  Both these changes made it necessary to change the test suite's ftp server
+  code, and all FTP test cases need to be checked and adjusted!
+
+Daniel (27 November 2001)
+- Hans Steegers pointed out that the telnet code read from stdout, not stdin
+  as it is supposed to do!
+
+Version 7.9.2-pre6
+
+Daniel (27 November 2001)
+- Eric Lavigne's minor changes to build on MacOS before OS X were applied.
+
+- greep at mindspring.com provided a main index.html page for our release
+  archive docs directory. It just links to all the existing HTML files, but
+  I think it may come useful to people.
+
+- There's now some initial code to support the EPSV FTP command. That should
+  be used to do passive transfers IPv6-style. The code is still #if 0'ed in
+  lib/ftp.c as I have no IPv6 ftp server to test this with.
+
+Daniel (26 November 2001)
+- Robert Schlabbach had problems to understand how to do resumed transfers,
+  and I clarified the man page -C section somewhat.
+
+Version 7.9.2-pre5
+
+Daniel (22 November 2001)
+- Andr<64>s Garc<72>a helped me out to track down the roots of bug report #479537,
+  which was concerning curl returning the wrong error code when failing to
+  connect. This didn't happen on all systems, and more specificly I've so far
+  only seen this happen on IPv4-only Linux hosts.
+
+- I applied the fixes for the two bugs Eric Lavigne found when doing his MacOS
+  port. A missing comma in arpa_telnet.h and a pretty wild write in the FTP
+  response reader function. The latter write is however likely to occur in our
+  own buffer unless very big FTP server replies (>25K) are read. I've never
+  seen such a reply ever, so I think this is a relatively minor risk.
+
+Daniel (21 November 2001)
+- Moonesamy provided code to prevent junk from being output when libcurl
+  returns an error code but no error description and that corrects how make is
+  run in the Makefile.dist file (that appears as root Makefile in release
+  archives).
+
+- Eric Lavigne mailed me bugfixes and patches for building libcurl on MacOS
+  (non-X).
+
+- Kevin Roth modified the cygwin files once again, now to build against the
+  shared OpenSSL DLLs.
+
+Version 7.9.2-pre4
+
+Daniel (20 November 2001)
+- Georg Horn brought a patch that introduced CURLINFO_STARTTRANSFER_TIME,
+  complete with man page updates!
+
+Daniel (19 November 2001)
+- Miklos Nemeth provided details enough to update the Borland makefile
+  properly.
+
+- Lars M Gustafsson found a case with a bad free(). In fact, it was so bad I'm
+  amazed we never saw this before!
+
+- Kevin Roth patched the cygwin Makfile.
+
+Daniel (16 November 2001)
+- Klevtsov Vadim fixed a bug in how time-conditionals were sent when doing
+  HTTP.
+
+Version 7.9.2-pre3
+
+Daniel (14 November 2001)
+- Samuel Listopad patched away the problem with SSL we got when someone call
+  curl_global_init() => curl_global_cleanup() => curl_global_init(). The
+  second init would not "take" and SSL would be unusable with curl from that
+  point. This doesn't change the fact that calling the functions that way is
+  wrong. curl_global_init() should be called exactly once and not more.
+
+Daniel (13 November 2001)
+- Fixed some minor variable type mixups in ftp.c that caused compiler warnings
+  on HP-UX 11.00.
+
+- The FTP fix I did yesterday used an uninitialized variable that caused
+  spurious errors when doing FTP.
+
+Version 7.9.2-pre2
+
+Daniel (12 November 2001)
+- Ricardo Cadime fell over a multiple-requests problem when first a FTP
+  directory fetch failed and then a second request is made after that. The
+  second request happened to get the FTP server response back from the
+  previous request, when it did its initial CWD command.
+
+- Bjorn Reese pointed out that we could improve the time diff function to
+  prevent truncation a bit.
+
+- Kai-Uwe Rommel made me aware that -p (http proxy tunnel) silly enough didn't
+  work for plain HTTP requests! So I made that work.
+
+Version 7.9.2-pre1
+
+Daniel (12 November 2001)
+- Rewrote the Curl_ConnectHTTPProxyTunnel(). It should now not only work a lot
+  faster, it should also support such ("broken") proxies that John Lask
+  previously have reported problems with. His proxy sends a trailing zero byte
+  after the end of the (proxy-) headers. I've tested this myself and it seems
+  to work on a proxy the previous version also worked with...! This rewrite is
+  due to the problems John Lask previously experienced.
+
+- Andr<64>s Garc<72>a found out why the "current speed" meter sometimes showed 2048K
+  for very quick transfers. It turned out the "time diff"-function returned a
+  zero millisecond diff. We now always say it is at least one millisecond! In
+  reality, these timers very rarely have that good resolution so even though
+  the time diff was longer than 1 millisecond, it was reported as no diff.
+
+- I also modified the getinfo() again when returning times, as Paul Harrington
+  reports that 7.9.1 only returns times with 1 second accuracy, which indeed
+  is wrong.
+
+Daniel (8 November 2001)
+- Marcus Webster found out that curl_formadd() could read one byte outside a
+  buffer boundary, which then of course could lead to a crash. Marcus also
+  gracefully provided a patch for this this.
+
+- Glen Scott ran configure on his Cobalt Qube and it didn't figure out the
+  correct way of calling gethostbyname_r() and thus failed to resolve hosts.
+  This is two errors: it shouldn't continue the configure script if it finds
+  gethostbyname_r() but can't figure out how to use it, and it should really
+  figure out how to use it as it was running Linux and we know how that
+  works...
+ 
+Daniel (7 November 2001)
+- docs/VERSIONS is a new file in the archive that explains the version number
+  system we use in the curl project.
+
+- Did some more fixes that now makes libcurl only ignore signals as long as
+  it needs to, and then restore (if any) previous signal handler again.
+
+Daniel (6 November 2001)
+- Enrik Berkhan posted bug report #478780, in which he very correctly pointed
+  out two bad timeout matters in libcurl: we didn't restore the sigaction
+  struct (the alarm handler for SIGALRM) nor did we restore the previous
+  alarm() timeout that could've been set by a "parent" process or similar.
+
+- Kevin Roth made the cygwin binary get stripped before install.
+
+Daniel (5 November 2001)
+- Detlef Schmier reported that curl didn't compile using Solaris 8 with the
+  native cc compiler. It was due to a bad function prototype. Fixed now.
+  Unfortunately, I can't enable the -Wstrict-prototypes in my debug builds
+  though, as gcc then complains like crazy on OpenSSL include files... :-(
+
+- John Lask provided SSL over HTTP proxy fixes. They'll need some tweaking
+  to work on all platforms.
+
+- John Lask added the -1/--TLSv1 options that forces SSL into using TLS
+  version 1 when speaking HTTPS.
+
+- John Lask brought a brand new VC++ makefile for the lib directory, that
+  works a lot better than the previous!
+
+- Ramana Mokkapati brought some clever insights on the LDAP failures (bug
+  report #475407), and his suggested changes are now applied.

-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.

- - 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

-
-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 J<>rn'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
-
- J<>rn 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)
- - J<>rn 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.
-
- J<>rn 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.
-
- J<>rn 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.
-
 Version 5.3a (win32 only)

CHANGES.1999

@@ -0,0 +1,835 @@
+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 J<>rn'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
+
+ J<>rn 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)
+ - J<>rn 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.
+
+ J<>rn 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.
+
+ J<>rn 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.

+Version Numbers and Releases
+
+ Curl is not only curl. Curl is also libcurl. They're actually individually
+ versioned, but they mostly follow each other rather closely.
+
+ The version numbering is always built up using the same system:
+
+        X.Y[.Z][-preN]
+
+ Where
+   X is main version number
+   Y is release number
+   Z is patch number
+   N is pre-release number
+
+ One of these numbers will get bumped in each new release. The numbers to the
+ right of a bumped number will be reset to zero. If Z is zero, it is not
+ included in the version number. The pre release number is only included in
+ pre releases (they're never used in public, official, releases).
+
+ The main version number will get bumped when *really* big, world colliding
+ changes are made. The release number is bumped when big changes are
+ performed. The patch number is bumped when the changes are mere bugfixes and
+ only minor feature changes. The pre-release is a counter, to identify which
+ pre-release a certain release is.
+
+ When reaching the end of a pre-release period, the version without the
+ pre-release part will be released as a public release.
+
+ It means that after release 1.2.3, we can release 2.0 if something really big
+ has been made, 1.3 if not that big changes were made or 1.2.4 if mostly bugs
+ were fixed. Before 1.2.4 is released, we might release a 1.2.4-pre1 release
+ for the brave people to try before the actual release.
+
+ Bumping, as in increasing the number with 1, is unconditionally only
+ affecting one of the numbers (except the ones to the right of it, that may be
+ set to zero). 1 becomes 2, 3 becomes 4, 9 becomes 10, 88 becomes 89 and 99
+ becomes 100. So, after 1.2.9 comes 1.2.10. After 3.99.3, 3.100 might come.
+
+ All original curl source release archives are named according to the libcurl
+ version (not according to the curl client version that, as said before, might
+ differ).
+
+ As a service to any application that might want to support new libcurl
+ features while still being able to build with older versions, all releases
+ have the libcurl version stored in the curl/curl.h file using a static
+ numbering scheme that can be used for comparison. The version number is
+ defined as:
+        
+        #define LIBCURL_VERSION_NUM 0xXXYYZZ
+
+ Where XX, YY and ZZ are the main version, release and patch numbers in
+ hexadecimal. All three numbers are always represented using two digits.  1.2
+ would appear as "0x010200" while version 9.11.7 appears as "0x090b07".
+
+ This 6-digit hexadecimal number does not show pre-release number, and it is
+ always a greater number in a more recent release. It makes comparisons with
+ greater than and less than work.

-curl_formparse() is used to append sections when building a multipart/formdata
-HTTP POST (sometimes refered to as rfc1867-style posts). Append one section at
-a time until you've added all the sections you want included and then you pass
-the \fIfirstitem\fP pointer as parameter to \fBCURLOPT_HTTPPOST\fP.
-\fIlastitem\fP is set after each call and on repeated invokes it should be
-left as set to allow repeated invokes to find the end of the list in a faster
-way.  \fIstring\fP must be a zero terminated string abiding to the syntax
-described in a section below
-
-The pointers \fI*firstitem\fP and \fI*lastitem\fP should both be pointing to
-NULL in the first call to this function. All list-data will be allocated by
-the function itself. You must call \fIcurl_formfree\fP after the form post has
-been done to free the resources again.
-
-This function will copy all input data and keep its own version of it
-allocated until you call \fIcurl_formfree\fP. When you've passed the pointer
-to \fIcurl_easy_setopt\fP, you must not free the list until after you've

-Whenever you specify a file to read from, you can optionally specify the
-content-type as well. The content-type is passed to the server together with

+PROGRAMMING WITH LIBCURL
+
+About this Document
+
+ This document will attempt to describe the general principle and some basic
+ approach to consider when programming with libcurl. The text will focus
+ mainly on the C/C++ interface but might apply fairly well on other interfaces
+ as well as they usually follow the C one pretty closely.
+
+ This document will refer to 'the user' as the person writing the source code
+ that uses libcurl. That would probably be you or someone in your position.
+ What will be generally refered to as 'the program' will be the collected
+ source code that you write that is using libcurl for transfers. The program
+ is outside libcurl and libcurl is outside of the program.
+
+
+Building
+
+  Compiling the Program
+
+  Linking the Program with libcurl
+
+  SSL or Not
+
+
+Global Preparation
+
+ The program must initialize some of the libcurl functionality globally. That
+ means it should be done exactly once, no matter how many times you intend to
+ use the library. Once for your program's entire life time. This is done using
+
+    curl_global_init()
+
+ and it takes one parameter which is a bit pattern that tells libcurl what to
+ intialize. Using CURL_GLOBAL_ALL will make it initialize all known internal
+ sub modules, and might be a good default option. The current two bits that
+ are specified are:
+
+  CURL_GLOBAL_WIN32 which only does anything on Windows machines. When used on
+  a Windows machine, it'll make libcurl intialize the win32 socket
+  stuff. Without having that initialized properly, your program cannot use
+  sockets properly. You should only do this once for each application, so if
+  your program already does this or of another library in use does it, you
+  should not tell libcurl to do this as well.
+
+  CURL_GLOBAL_SSL which only does anything on libcurls compiled and built
+  SSL-enabled. On these systems, this will make libcurl init OpenSSL properly
+  for this application. This is only needed to do once for each application so
+  if your program or another library already does this, this bit should not be
+  needed.
+
+ libcurl has a default protection mechanism that detects if curl_global_init()
+ hasn't been called by the time curl_easy_perform() is called and if that is
+ the case, libcurl runs the function itself with a guessed bit pattern. Please
+ note that depending solely on this is not considered nice nor very good.
+
+ When the program no longer uses libcurl, it should call
+ curl_global_cleanup(), which is the opposite of the init call. It will then
+ do the reversed operations to cleanup the resources the curl_global_init()
+ call initialized.
+
+ Repeated calls to curl_global_init() and curl_global_cleanup() should be
+ avoided. They should be called once each.
+
+Handle the easy libcurl
+
+ libcurl version 7 is oriented around the so called easy interface. All
+ operations in the easy interface are prefixed with 'curl_easy'.
+
+ Future libcurls will also offer the multi interface. More about that
+ interface, what it is targeted for and how to use it is still only debated on
+ the libcurl mailing list and developer web pages. Join up to discuss and
+ figure out!
+
+ To use the easy interface, you must first create yourself an easy handle. You
+ need one handle for each easy session you want to perform. Basicly, you
+ should use one handle for every thread you plan to use for transferring. You
+ must never share the same handle in multiple threads.
+
+ Get an easy handle with
+
+    easyhandle = curl_easy_init();
+
+ It returns an easy handle. Using that you proceed to the next step: setting
+ up your preferred actions. A handle is just a logic entity for the upcoming
+ transfer or series of transfers. One of the most basic properties to set in
+ the handle is the URL. You set your preferred URL to transfer with
+ CURLOPT_URL in a manner similar to:
+
+    curl_easy_setopt(easyhandle, CURLOPT_URL, "http://curl.haxx.se/");
+
+ Let's assume for a while that you want to receive data as the URL indentifies
+ a remote resource you want to get here. Since you write a sort of application
+ that needs this transfer, I assume that you would like to get the data passed
+ to you directly instead of simply getting it passed to stdout. So, you write
+ your own function that matches this prototype:
+
+    size_t write_data(void *buffer, size_t size, size_t nmemb, void *userp);
+
+ You tell libcurl to pass all data to this function by issuing a function
+ similar to this:
+
+    curl_easy_setopt(easyhandle, CURLOPT_WRITEFUNCTION, write_data);
+
+ You can control what data your function get in the forth argument by setting
+ another property:
+
+    curl_easy_setopt(easyhandle, CURLOPT_FILE, &internal_struct);
+
+ Using that property, you can easily pass local data between your application
+ and the function that gets invoked by libcurl. libcurl itself won't touch the
+ data you pass with CURLOPT_FILE.
+
+ There are of course many more options you can set, and we'll get back to a
+ few of them later. Let's instead continue to the actual transfer:
+
+    success = curl_easy_perform(easyhandle);
+
+ The curl_easy_perform() will connect to the remote site, do the necessary
+ commands and receive the transfer. Whenever it receives data, it calls the
+ callback function we previously set. The function may get one byte at a time,
+ or it may get many kilobytes at once. libcurl delivers as much as possible as
+ often as possible. Your callback function should return the number of bytes
+ it "took care of". If that is not the exact same amount of bytes that was
+ passed to it, libcurl will abort the operation and return with an error code.
+
+ When the transfer is complete, the function returns a return code that
+ informs you if it succeeded in its mission or not. If a return code isn't
+ enough for you, you can use the CURLOPT_ERRORBUFFER to point libcurl to a
+ buffer of yours where it'll store a human readable error message as well.
+
+ If you then want to transfer another file, the handle is ready to be used
+ again. Mind you, it is even preferred that you re-use an existing handle if
+ you intend to make another transfer. libcurl will then attempt to re-use the
+ previous
+
+When It Doesn't Work
+
+ There will always be times when the transfer fails for some reason. You might
+ have set the wrong libcurl option or misunderstood what the libcurl option
+ actually does, or the remote server might return non-standard replies that
+ confuse the library which then confuses your program.
+
+ There's one golden rule when these things occur: set the CURLOPT_VERBOSE
+ option to TRUE. It'll cause the library to spew out the entire protocol
+ details it sends, some internal info and some received protcol data as well
+ (especially when using FTP). If you're using HTTP, adding the headers in the
+ received output to study is also a clever way to get a better understanding
+ wht the server behaves the way it does. Include headers in the normal body
+ output with CURLOPT_HEADER set TRUE.
+
+Upload Data to a Remote Site
+
+ libcurl tries to keep a protocol independent approach to most transfers, thus
+ uploading to a remote FTP site is very similar to uploading data to a HTTP
+ server with a PUT request.
+
+ Of course, first you either create an easy handle or you re-use one existing
+ one. Then you set the URL to operate on just like before. This is the remote
+ URL, that we now will upload.
+
+ Since we write an application, we most likely want libcurl to get the upload
+ data by asking us for it. To make it do that, we set the read callback and
+ the custom pointer libcurl will pass to our read callback. The read callback
+ should have a prototype similar to:
+
+   size_t function(char *buffer, size_t size, size_t nitems, void *userp);
+
+ Where buffer is the pointer to a buffer we fill in with data to upload and
+ size*nitems is the size of the buffer. The 'userp' pointer is the custom
+ pointer we set to point to a struct of ours to pass private data between the
+ application and the callback.
+
+    curl_easy_setopt(easyhandle, CURLOPT_READFUNCTION, read_function);
+
+    curl_easy_setopt(easyhandle, CURLOPT_INFILE, &filedata);
+
+ Tell libcurl that we want to upload:
+
+    curl_easy_setopt(easyhandle, CURLOPT_UPLOAD, TRUE);
+
+ A few protocols won't behave properly when uploads are done without any prior
+ knowledge of the expected file size. HTTP PUT is one example [1]. So, set the
+ upload file size using the CURLOPT_INFILESIZE like this:
+
+    curl_easy_setopt(easyhandle, CURLOPT_INFILESIZE, file_size);
+
+ So, then you call curl_easy_perform() this time, it'll perform all necessary
+ operations and when it has invoked the upload it'll call your supplied
+ callback to get the data to upload. The program should return as much data as
+ possible in every invoke, as that is likely to make the upload perform as
+ fast as possible. The callback should return the number of bytes it wrote in
+ the buffer. Returning 0 will signal the end of the upload.
+
+
+-----
+Footnotes:
+
+[1] = HTTP PUT without knowing the size prior to transfer is indeed possible,
+      but libcurl does not support the chunked transfers on uploading that is
+      necessary for this feature to work. We'd gratefully appreciate patches
+      that bring this functionality...

-## Makefile for building libcurl.lib with MSVC6
-## Use: nmake -f makefile.vc6 [release | release-ssl | debug]
-##      (default is release)

-## Originally written by: Troy Engel <tengel@sonic.net>
-## Updated by: Craig Davison <cd@securityfocus.com>
-## Updated by: SM <sm@technologist.com>
+# Makefile for building libcurl with MSVC6
+#
+# Usage: see usage message below
+#        Should be invoked from \lib directory
+#        Edit the paths and desired library name
+#        SSL path is only required if you intend compiling
+#        with SSL.
+#
+# This make file leaves the result either a .lib or .dll file
+# in the \lib directory. It should be called from the \lib
+# directory.
+#
+# An option would have been to allow the source directory to
+# be specified, but I saw no requirement.
+#
+# Another option would have been to leave the .lib and .dll
+# files in the "cfg" directory, but then the make file
+# in \src would need to be changed.

+
+  -------------------------------------------
+  GOALS
+
+  o Enable a "pull" interface. The application that uses libcurl decides where
+    and when to ask libcurl to get/send data.
+
+  o Enable multiple simultaneous transfers in the same thread without making it
+    complicated for the application.
+
+  o Enable the application to select() on its own file descriptors and curl's
+    file descriptors simultaneous easily.
+  
+  Example source using this interface: http://curl.haxx.se/dev/multi-app.c
