CHANGES.0

Daniel (20 February 2001)
- Added the docs/examples/win32sockets.c file for our windows friends.

- Linus Nielsen Feltzing provided brand new TELNET functionality and
  improvements:

  * Negotiation is now passive. Curl does not negotiate until the peer does.
  * Possibility to set negotiation options on the command line, currently only
    XDISPLOC, TTYPE and NEW_ENVIRON (called NEW_ENV).
  * Now sends the USER environment variable if the -u switch is used.
  * Use -t to set telnet options (Linus even updated the man page, awesome!)

- Haven't done this big changes to curl for a while. Moved around a lot of
  struct fields and stuff to make multiple connections get connection specific
  data in separate structs so that they can co-exist in a nice way. See the
  mailing lists for discussions around how this is gonna be implemented. Docs
  and more will follow.

  Studied the HTTP RFC to find out better how persistent connections should
  work. Seems cool enough.

Daniel (19 February 2001)
- Bob Schader brought me two files that help set up a MS VC++ libcurl project
  easier. He also provided me with an up-to-date libcurl.def file.

- I moved a bunch of prototypes from the public <curl/curl.h> file to the
  library private urldata.h. This is because of the upcoming changes. The
  low level interface is no longer being planned to become reality.

Daniel (15 February 2001)
- CURLOPT_POST is not required anymore. Just setting the POST string with
  CURLOPT_POSTFIELDS will switch on the HTTP POST. Most other things in
  libcurl already works this way, i.e they require only the parameter to
  switch on a feature so I think this works well with the rest. Setting a NULL
  string switches off the POST again.

- Excellent suggestions from Rich Gray, Rick Jones, Johan Nilsson and Bjorn
  Reese helped me define a way how to incorporate persistent connections into
  libcurl in a very smooth way. If done right, no change may have to be made
  to older programs and they will just start using persistent connections when
  applicable!

Daniel (13 February 2001)
- Changed the word 'timeouted' to 'timed out' in two different error messages.
  Suggested by Larry Fahnoe.

Version 7.6.1

Daniel (9 February 2001)
- Frank Reid and Cain Hopwood provided information and research around a HTTPS
  PUT/upload problem we seem to have. No solution found yet.

Daniel (8 February 2001)
- An interesting discussion is how to specify an empty password without having
  curl ask for it interactively? The current implmentation takes an empty
  password as a request for a password prompt. However, I still want to
  support a blank user field. Thus, today if you enter "-u :" (without user
  and password) curl will prompt for the password. Tricky. How would you
  specify you want the prompt otherwise?

- Made the netrc parse result possible to use for other protocols than FTP and
  HTTP (such as the upcoming TELNET fixes).

- The previously mentioned "MSVC++ problems" turned out to be a non-issue.

- Added a HTTP file upload code example in the docs/examples/ section on
  request.

- Adjusted the FTP response fix slightly.

Version 7.6.1-pre3

Daniel (7 February 2001)
- S. Moonesamy found a flaw in the response reading function for FTP that
  could make libcurl not get out of the loop properly when it should, if
  libcurl got -1 returned when reading the socket.

- I found a similar mistake in http.c when using a proxy and reading the
  results from the proxy connection.

Daniel (6 February 2001)
- S. Moonesamy pointed out that the VC makefile in src/ needed the libpath set
  for the debug build to work.

- Daniel Gehriger stepped in to assist with the VC++ stuff Robert Weaver
  brought up yesterday.

Daniel (5 February 2001)
- Jun-ichiro itojun Hagino brought a big patch that brings IPv6-awareness to
  a bunch of different areas within libcurl.

- Robert Weaver told me about the problems the MS VC++ 6.0 compiler has with
  the 'static' keyword on a number of libcurl functions. I might need to add a
  patch that redefines static when libcurl is compiled with that compiler.
  How do I know when VC++ compiles, anyone?

Daniel (4 February 2001)
- curl_getinfo() was extended with two new options:
  CURLINFO_CONTENT_LENGTH_DOWNLOAD and CURLINFO_CONTENT_LENGTH_UPLOAD. They
  return the full assumed content length of the transfer in the given
  direction. The CURLINFO_CONTENT_LENGTH_DOWNLOAD will be the Content-Length:
  size of a HTTP download. Added descriptions to the man page as well. This
  was done after discussions with Bob Schader.

Daniel (3 February 2001)
- Ingo Ralf Blum provided another fix that makes curl build under the more
  recent cygwin installations. It seems they've changed the preset defines to
  not include WIN32 anymore.

Version 7.6.1-pre2

Daniel (31 January 2001)
- Curl_read() and curl_read() now return a ssize_t for the size, as it had to
  be able to return -1. The telnet support crashed due to this and there was a
  possibility to weird behavior all over. Linus Nielsen Feltzing helped me
  find this.

- Added a configure.in check for a working getaddrinfo() if IPv6 is requested.
  I also made the configure script feature --enable-debug which sets a couple
  of compiler options when used. It assumes gcc.

Daniel (30 January 2001)
- I finally took a stab at the long-term FIXME item I've had on myself, and
  now libcurl will properly work when doing a HTTP range-request that follows
  a Location:. Previously that would make libcurl fail saying that the server
  doesn't seem to support range requests.

Daniel (29 January 2001)
- I added a test case for the HTTP PUT resume thing (test case 33).

Version 7.6.1-pre1

Daniel (29 January 2001)
- Yet another Content-Range change. Ok now? Bob Schader checks from his end 
  and it works for him.

Daniel (27 January 2001)
- So the HTTP PUT resume fix wasn't good. There should appearantly be a
  Content-Range header when resuming a PUT.

- I noticed I broke the download-check that verifies that a resumed HTTP
  download is actually resumed. It got broke because my new 'httpreq' field
  in the main curl struct. I should get slapped. I added a test case for
  this now, so I won't be able to ruin this again without noticing.

- Added a test case for content-length verifying when downloading HTTP.

- Made the progress meter title say if the transfer is being transfered. It
  makes the output slightly better for resumes.

- When dealing with Location: and HTTP return codes, libcurl will not attempt
  to follow the spirit of RFC2616 better. It means that when POSTing to a
  URL that is being following to a second place, the standard will judge on
  what to do. All HTTP codes except 303 and 305 will cause curl to make a
  second POST operation. 303 will make a GET and 305 is not yet supported.

  I also wrote two test cases for this POST/GET/Location stuff.

Version 7.6

Daniel (26 January 2001)
- Lots of mails back and forth with Bob Schader finally made me add a small
  piece of code in the HTTP engine so that HTTP upload resume works. You can
  now do an operation like 'curl -T file -C <offset> <URL>' and curl will PUT
  the ending part of the file starting at given offet to the specified URL.

Version 7.6-pre4

Daniel (25 January 2001)
- I took hold of Rick Jones' question why we don't use recv() and send() for
  reading/writing to the sockets and I've now modified the sread() and
  swrite() macros to use them instead. If nothing else, they could be tested
  in the next beta-round coming right up.

- Jeff Morrow found a problem with libcurl's usage of SSL_read() and supplied
  his research results in how to fix this. It turns out we have to invoke the
  function several times in some cases. The same goes for the SSL_write().

  I made some rather drastic changes all over libcurl to make all writes and
  reads get done on one single place so that this repeated-attempts thing
  would only have to be implemented at one point.

- Rick Jones spotted that the 'total time' counter really didn't measure the
  total time very accurate on subsecond levels.

- Johan Nilsson pointed out the need to more clearly specify that the timeout
  value you set for a download is for the *entire* download. There's currently
  no option available that sets a timeout for the connection phase only.

Daniel (24 January 2001)
- Ingo Ralf Blum submitted a series of patches required to get curl to compile
  properly with cygwin.

- Robert Weaver posted a fix for the win32 section of the curl_getenv() code
  that corrected a potential memory leak.

- Added comments in a few files in a sudden attempt to make the sources more
  easy to read and understand!

Daniel (23 January 2001)
- Added simple IPv6 detection in the configure script and made the version
  string add 'ipv6' to the enable section in that case. ENABLE_IPV6 will be
  set if curl is compiled with IPv6 support enabled.

- Added a parser for IPv6-style specified IP-addresses in a URL. Thus, when
  IPv6 gets enabled soon, we can use URLs like '[0::1]:80'...

- Made the URL globbing in the client possible to fail silently if there's an
  error in the globbing. It makes it almost intuitive, so when you don't
  follow the syntax rules, globbing is simply switched off and the raw string
  is used instead.

  I still think we'll get problems with IPv6-style IP-addresses when we *want*
  globbing on parts of the URL as the initial part of the URL will for sure
  seriously confuse the globber.

Daniel (22 January 2001)
- Björn Stenberg supplied a progress meter patch that makes it look better even
  during slow starts. Previously it made some silly assumptions...

- Added two FTP tests for -Q and -Q - stuff since it was being discussed on
  the mailing list. Had to correct the ftpserver.pl too as it bugged slightly.

Daniel (19 January 2001)
- Made the Location: parsers deal with any-length URLs. Thus I removed the last
  code that restricts the length of URLs that curl supports.

- Added a --globoff test case (#28) and it quickly identified a memory problem
  in src/main.c that I took care of.

Version 7.6-pre3

Daniel (17 January 2001)
- Made the two former files lib/download.c and lib/highlevel.c become the new
  lib/transfer.c which makes more sense. I also did the rename from Transfer()
  to Curl_Transfer() in the other source files that use the transfer function
  in the spirit of using Curl_ prefix for library-scoped global symbols.

Daniel (11 January 2001)
- Added -g/--globoff that switches OFF the URL globbing and thus enables {}[]
  letters to be part of the URL. Do note that RFC2396 section 2.4.3 explicitly
  mention these letters to be escaped. This was posted as a feature request by
  Jorge Gutierrez and as a bug by Terry.

- Short options to curl that requires parameters can now be specified without
  having the option and its parameter space separated. -ofile works as good as
  -o file. -m20 is equal to -m 20. Do note that this goes for single-letter
  options only, verbose --long-style options still must be separated with
  space from their parameters.

Daniel (8 January 2001)
- Francis Dagenais reported that the SCO compiler still fails when compiling
  curl due to that getpass_r() prototype. I've now put it around #ifndef
  HAVE_GETPASS_R in an attempt to please the SCO systems.

- Made some minor corrections to get the client to cleanup properly and I made
  the separator work again when getting multiple globbed URLs to stdout.

- Worked with Loic Dachary to get the make dist and make distcheck work
  correctly. The 'maketgz' script is now using the automake generated 'make
  dist' when creating release archives. Loic successfully made 'make rpms'
  automatically build RPMs!

Loic Dachary (6 January 2001)
- Automated generation of rpm packages, no need to be root.

- make distcheck generates a proper distribution (EXTRA_DIST
  in all Makefile.am modified to match FILES).

Daniel (5 January 2001)
- Huge client-side hack: now multiple URLs are supported. Any number of URLs
  can be specified on the command line, and they'll all be downloaded. There
  must be a corresponding -o or -O for each URL or the data will be written to
  stdout. This needs more testing, time to release a 7.6-pre package.

- The krb4 support was broken in the release. Fixed now.

- Huge internal symbol rename operation. All non-static but still lib-internal
  symbols should now be prefixed with 'Curl_' to prevent collisions with other
  libs. All public symbols should be prefixed with 'curl_' and the rest should
  be static and thus invisible to the outside world. I updated the INTERNALS
  document to say this as well.

Version 7.5.2

Daniel (4 January 2001)
- As Kevin P Roth suggested, I've added text to the man page for every command
  line option and what happens when you specify that option more than
  once. That hasn't been exactly crystal clear before.

- Made the configure script possible to run from outside the source-tree. For
  odd reasons I can't build curl properly outside though. It has to do with
  curl's dependencies on libcurl...

- Cut off all older (dated 1999 and earlier) CHANGES entries from this file.
  The older piece is named CHANGES.0 and is added to the CVS repository in
  case anyone would need it.

- I added another file 'CVS-INFO' to the CVS. It contains information about
  files in the CVS that aren't included in release archives and how to build
  curl when you get the sources off CVS.

- Updated CONTRIBUTE and FAQ due to the new license.

Daniel (3 January 2001)
- Renamed README.libcurl to LIBCURL

- Changed headers in all sources files to the new dual license concept of
  curl: use the MIT/X derivate license *or* MPL. The LEGAL file was updated
  accordingly and the MPL 1.1 and MIT/X derivate licenses are now part of the
  release archive.
Daniel (30 December 2000)
- Made all FTP commands get sent with the trailing CRLF in one single write()
  as splitting them up seems to confuse at least some firewalls (FW-1 being
  one major).

Daniel (19 December 2000)
- Added file desrciptor and FILE handle leak detection to the memdebug system
  and thus I found and removed a file descriptor leakage in the ftp parts
  that happened when you did PORTed downloads.

- Added an include <stdio.h> in <curl/curl.h> since it uses FILE *.

Daniel (12 December 2000)
- Multiple URL downloads with -O was still bugging. Not anymore I think or
  hope, or at least I've tried... :-O

- Francois Petitjean fixed another -O problem

Version 7.5.1

Daniel (11 December 2000)
- Cleaned up a few of the makefiles to use unix-style newlines only. As Kevin
  P Roth found out, at least one CVS client behaved wrongly when it found
  different newline conventions within the same file.

- Albert Chin-A-Young corrected the LDFLAGS use in the configure script for
  the SSL stuff.

Daniel (6 December 2000)
- Massimo Squillace correctly described how libcurl could use session ids when
  doing SSL connections.

- James Griffiths found out that curl would crash if the file you specify with
  -o is shorter than the URL! This took some hours to fully hunt down, but it
  is fixed now.

Daniel (5 December 2000)
- Jaepil Kim sent us makefiles that build curl using the free windows borland
  compiler. The root makefile now accepts 'make borland' to build curl with
  that compiler.

- Stefan Radman pointed out that the test makefiles didn't use the PERL
  variable that the configure scripts figure out. Actually, you still need
  perl in the path for the test suite to run ok.

- Rich Gray found numerous portability problems:
  * The SCO compiler got an error on the getpass_r() prototype in getpass.h
    since the curl one differed from the SCO one
  * The HPUX compiler got an error because of how curl did the sigaction
    stuff and used a define HPUX doesn't have (or need).
  * A few more problems remain to be researched.

- Paul Harrington experienced a core dump using https. Not much details yet.

Daniel (4 December 2000)
- Jörn Hartroth fixed a problem with multiple URLs and -o/-O.

Version 7.5

Daniel (1 December 2000)
- Craig Davison gave us his updates on the VC++ makefiles, so now curl should
  build fine with the Microsoft compiler on windows too.

- Fixed the libcurl versioning so that we don't ruin old programs when
  releasing new shared library interfaces.

Daniel (30 November 2000)
- Renamed docs/README.curl to docs/MANUAL to better reflect what the document
  actually contains.

Daniel (29 November 2000)
- I removed a bunch of '#if 0' sections from the code. They only make things
  harder to follow. After all, we do have all older versions in the CVS.

Version 7.5-pre5

Daniel (28 November 2000)
- I filled in more error codes in the man page error code list that had been
  lagging.

- James Griffiths mailed me a fine patch that introduces the CURLOPT_MAXREDIRS
  libcurl option. When used, it'll prevent location following more than the
  set number of times. It is useful to break out of endless redirect-loops.

Daniel (27 November 2000)
- Added two test cases for file://.

Daniel (22 November 2000)
- Added the libcurl CURLOPT_FILETIME setopt, when set it tries to get the
  modified time of the remote document. This is a special option since it
  involves an extra set of commands on FTP servers. (Using the MDTM command
  which is not in the RFC959)

  curl_easy_getinfo() got a corresponding CURLINFO_FILETIME to get the time
  after a transfer. It'll return a zero if CURLOPT_FILETIME wasn't used or if
  the time wasn't possible to get.

  --head/-I used on a FTP server will now present a 'Last-Modified:' header
  if curl could get the time of the specified file.

- Added the option '--cacert [file]' to curl, which allows a specified PEM
  file to be used to verify the peer's certificate when doing HTTPS
  connections. This has been requested, rather recently by Hulka Bohuslav but
  others have asked for it before as well.

Daniel (21 November 2000)
- Numerous fixes the test suite has brought into the daylight:

   * curl_unescape() could return a too long string
   * on ftp transfer failures, there could be memory leaks
   * ftp CWD could use bad directory names
   * memdebug now uses the mprintf() routines for better portability
   * free(NULL) removed when doing resumed transfers

- Added a bunch of test cases for FTP.

- General cleanups to make less warnings with gcc -Wall -pedantic.

- I made the tests/ftpserver.pl work with the most commonly used ftp
  operations. PORT, PASV, RETR, STOR, LIST, SIZE, USER, PASS all work now. Now
  all I have to do is integrate the ftp server doings in the runtests.pl
  script so that ftp tests can be run the same way http tests already run.

Daniel (20 November 2000)
- Made libcurl capable of dealing with any-length URLs. The former limit of
  4096 bytes was a bit annoying when people wanted to use curl to really make
  life tough on a web server. Now, the command line limit is the most annoying
  but that can be circumvented by using a config file.

  NOTE: there is still a 4096-byte limit on URLs extracted from Location:
  headers.

- Corrected the spelling of 'resolve' in two error messages.

- Alexander Kourakos posted a bug report and a patch that corrected it! It
  turned out that lynx and wget support lowercase environment variable names
  where curl only looked for the uppercase versions. Now curl will use the
  lowercase versions if they exist, but if they don't, it'll use the uppercase
  versions.

Daniel (17 November 2000)
- curl_formfree() was added. How come no one missed that one before? I ran the
  test suite with the malloc debug enabled and got lots of "nice" warnings on
  memory leaks. The most serious one was this. There were also leaks in the
  cookie handling, and a few errors when curl failed to connect and similar
  things. More tests cases were added to cover up and to verify that these
  problems have been removed.

- Mucho updated config file parser (I'm dead tired of all the bug reports and
  weird behaviour I get on the former one). It works slightly differently now,
  although I doubt many people will notice the differences. The main
  difference being that if you use options that require parameters, they must
  both be specified on the same line. With this new parser, you can also
  specify long options without '--' and you may separate options and
  parameters with : or =. It makes a config file line could look like:

        user-agent = "foobar and something"

  Parameters within quotes may contain spaces. Without quotes, they're
  expected to be a single non-space word.

  Had to patch the command line argument parser a little to make this work.

- Added --url as an option to allow the URL to be specified this way. It makes
  way nicer config files. The previous way of specifying URLs in the config
  file doesn't work anymore.

Daniel (15 November 2000)
- Using certain characters in usernames or passwords for HTTP authentication
  failed. This was due to the mprintf() that had a silly check for letters,
  and if they weren't isprint() they weren't outputed "as-is". This caused
  passwords and usernames using '§' (for example) to fail.

Version 7.4.2

Daniel (15 November 2000)
- 'tests/runtests.pl' now sorts the test cases properly when 'all' is used.

Daniel (14 November 2000)
- I fell over the draft-ietf-ftpext-mlst-12.txt Internet Draft titled
  "Extensions to FTP" that contains a defined way how the ftp command SIZE
  could be assumed to work.

- Laurent Papier posted a bug report about using "-C -" and FTP uploading a
  file that isn't prsent on the server. The server might then return a 550 and
  curl will fail. Should it instead as Laurent Papier suggests, start
  uploading from the beginning as a normal upload?

Daniel (13 November 2000)
- Fixed a crash with the followlocation counter.

- While writing test cases for the test suite, I discovered an old limitation
  that prevented -o and -T to be used at the same time. I removed this
  immediately as this has no relevance in the current libcurl.
  
- Chris Faherty fixed a free-twice problem in lib/file.c

- I fixed the perl http server problem in the test suite.

Version 7.4.2 pre4

Daniel (10 November 2000)
- I've (finally) started working on the curl test suite. It is in the new
  tests/ directory. It requires sh and perl. There's a TCP server in perl and
  most of the other stuff running a pretty simple shell script.

  I've only made four test cases so far, but it proves the system can work.

- Laurent Papier noticed that curl didn't set TYPE when doing --head checks
  for sizes on FTP servers. Some servers seem to return different sizes
  depending on whether ASCII or BINARY is used!

- Laurent Papier detected that if you appended a FTP upload and everything was
  already uploaded, curl would hang.

- Angus Mackay's getpass_r() in lib/getpass.c is now compliant with the
  getpass_r() function it seems some systems actually have.
  
- Venkataramana Mokkapati detected a bug in the cookie parser and corrected
  it.  If the cookie was set for the full host name (domain=full.host.com),
  the cookie was never sent back because of a faulty length comparison between
  the set domain length and the current host name.

Daniel (9 November 2000)
- Added a configure check for gethostbyname in -lsocket (OS/2 seems to need
  it). Added a check for RSAglue/rsaref for the cases where libcrypto is found
  but libssl isn't. I haven't verified this fix yet though, as I have no
  system that requires those libs to build.
  
Version 7.4.2 pre3

Daniel (7 November 2000)
- Removed perror() outputs from getpass.c. Angus Mackay also agreed to a
  slightly modified license of the getpass.c file as the prototype was changed.

Daniel (6 November 2000)
- Added possibility to set a password callback to use instead of the built-in.
  They're controled with curl_easy_setopt() of course, the tags are
  CURLOPT_PASSWDFUNCTION and CURLOPT_PASSWDDATA.

- Used T. Bharath's thinking and fixed the timers that showed terribly wrong
  times when location: headers were followed.

- Emmanuel Tychon discovered that curl didn't really like user names only in
  the URL. I corrected this and I also fixed the since long living problem
  with URL encoded user names and passwords in the URLs. They should work now.
  
Daniel (2 November 2000)
- When I added --interface, the new error code that was added with it was
  inserted in the wrong place and thus all error codes from 35 and upwards got
  increased one step. This is now corrected, we're back at the previous
  numbers. All new exit codes should be added at the end.

Daniel (1 November 2000)
- Added a check for signal() in the configure script so that if sigaction()
  isn't present, we can use signal() instead.

- I'm having a license discussion going on privately. The issue is yet again
  GPL-licensed programs that have problems with MPL. I am leaning towards
  making a kind of dual-license that will solve this once and for all...

Daniel (31 October 2000)
- Added the packages/ directory. I intend to let this contain some docs and
  templates on how to generate custom-format packages for various platforms.
  I've now removed the RPM related curl.spec files from the archive root.

Daniel (30 October 2000)
- T. Bharath brought a set of patches that bring new functionality to
  curl_easy_getinfo() and curl_easy_setopt(). Now you can request peer
  certificate verification with the *setopt() CURLOPT_SSL_VERIFYPEER option
  and then use the CURLOPT_CAINFO to set the certificate to verify the remote
  peer against. After an such an operation with a verification request, the
  *_getinfo() option CURLINFO_SSL_VERIFYRESULT will return information about
  whether the verification succeeded or not.  

Daniel (27 October 2000)
- Georg Horn brought us a splendid patch that solves the long-standing
  annoying problem with timeouts that made curl exit with silly exit codes
  (which as been commented out lately). This solution is sigaction() based and
  of course then only works for unixes (and only those unixes that actually
  have the sigaction() function).

Daniel (26 October 2000)
- Björn Stenberg supplied a patch that fixed the flaw mentioned by Kevin Roth
  that made the password get echoed when prompted for interactively. The
  getpass() function (now known as my_getpass()) was also fixed to not use any
  static buffers. This also means we cannot use the "standard" getpass()
  function even for those systems that have it, since it isn't thread-safe.
  
- Kevin Roth found out that if you'd write a config file with '-v url', the
  url would not be used as "default URL" as documented, although if you wrote
  it 'url -v' it worked! This has been corrected now.

- Kevin Roth's idea of using multiple -d options on the same command line was
  just brilliant, and I couldn't really think of any reason why we shouldn't
  support it! The append function always append '&' and then the new -d
  chunk. This enables constructs like the following:

        curl -d name=daniel -d age=unknown foobarsite.com

Daniel (24 October 2000)
- I fixed the lib/memdebug.c source so that it compiles on Linux and other
  systems. It will be useful one day when someone else but me wants to run the
  memory debugging system.

Daniel (23 October 2000)
- I modified the maketgz and configure scripts, so that the configure script
  will fetch the version number from the include/curl/curl.h header files, and
  then the maketgz doesn't have to rebuild the configure script when I build
  release-archives.

- Björn Stenberg and Linus Nielsen correctly pointed out that curl was silly
  enough to not allow @-letters in passwords when they were specified with the
  -u or -U flags (CURLOPT_USERPWD and CURLOPT_PROXYUSERPWD). This also
  suggests that curl probably should url-decode the password piece of an URL
  so that you could pass an encoded @-letter there...
  
Daniel (20 October 2000)
- Yet another http server barfed on curl's request that include the port
  number in the Host: header always. I now only include the port number if it
  isn't the default (80 for HTTP, 443 for HTTPS). www.perl.com turned out to
  run one of those nasty servers.

- The PHP4 module for curl had problems with referer that seems to have been
  corrected just yesterday. (Sterling Hughes of the PHP team confirmed this)

Daniel (17 October 2000)
- Vladimir Oblomov reported that the -Y and -y options didn't work. They
  didn't work for me either. This once again proves we should have that test
  suite...
  
- I finally changed the error message libcurl returns if you try a https://
  URL when the library wasn't build with SSL enabled. It will now return this
  error:
        "libcurl was built with SSL disabled, https: not supported!"

  I really hope it will make it a bit clearer to users where the actual
  problem lies.

Version 7.4.1

Daniel (16 October 2000)
- I forgot to remove some of the malloc debug defines from the makefiles in
  the release archive (of course).

Version 7.4

Daniel (16 October 2000)
- The buffer overflow mentioned below was posted to bugtraq on Friday 13th.

Daniel (12 October 2000)
- Colin Robert Phipps elegantly corrected a buffer overflow. It could be used
  by an evil ftp server to crash curl. I took the opportunity of replacing a
  few other sprintf()s into snprintf()s as well.

Daniel (11 October 2000)
- Found some more memory leaks. This new simple memory debugger has turned out
  really useful!

Version 7.4 pre6

Daniel (9 October 2000)
- Florian Koenig pointed out that the bool typedef in the curl/curl.h include
  file was breaking PHP 4.0.3 compiling. The bool typedef is not used in the
  public interface and was wrongly inserted in that header file.

- Jörg Hartroth corrected a minor memory leak in the src/urlglob.c stuff. It
  didn't harm anyone since the memory is free()ed on exit anyway.

- Corrected the src/main.c. We use the _MPRINTF_REPLACE #define to use our
  libcurl-printf() functions. This gives us snprintf() et al on all
  platforms. I converted the allocated useragent string to one that uses a
  local buffer.

- I've set an #if 0 section around the Content-Transfer-Encoding header
  generated in lib/formdata.c. This will hopefully make curl do more
  PHP-friendly multi-part posts.

Version 7.4 pre5

Daniel (9 October 2000)
- Nico Baggus found out that curl's ability to force a ASCII download when
  using FTP was no longer working! I corrected this. This problem was probably
  introduced when I redesigned libcurl for version 7.

- Georg Horn provided a source example that proved a memory leak in libcurl.
  I added simple memory debugging facilities and now we can make libcurl log
  all memory fiddling functions. An additional perl script is used to analyze
  the output logfile and to match malloc()s with free()s etc. The memory leak
  Georg found turned out to be the main cookie struct that cookie_cleanup()
  didn't free! The perl script is named memanalyze.pl and it is available in
  the CVS respository, not in the release archive.

Daniel (8 October 2000)
- Georg Horn found a GetHost() problem. It turned out it never assigned the
  pointer in the third argument properly! This could make a crash, or at best
  a memory leak!

Version 7.4 pre4

Daniel (6 October 2000)
- Is the -F post following the RFC 1867 spec? We had this dicussion on the
  mailing list since it appears curl can't post -F form posts to a PHP
  receiver... I've been in touch with the PHP developers about this.

- Domenico Andreoli found out that the long option '--proxy' wasn't working
  anymore! The option parser got confused when I added the --proxytunnel for
  7.3. This was indeed a very old flaw that hasn't turned up until now...

- Jörn Hartroth provided patches, updated makefiles and two new files for DLL
  stuff on win32. He also pointed out that lib source files were compiled with
  -I../src which isn't only wrong but plain stupid!

- Troels Walsted Hansen fixed a problem with HTTP resume. Curl previously used
  a local variable badly, that could lead to crashes.

Version 7.4 pre3

Daniel (4 October 2000)
- More docs written. The curl_easy_getinfo.3 man page is now pretty accurate,
  as is the -w section in curl.1. I added two options to enable the user to
  get information about the received headers' size and the size of the HTTP
  request. T. Bharath requested them.
  
Daniel (3 October 2000)
- Corrected a sever free() before use in the new add_buffer_send()! ;-)

Version 7.4 pre2

Daniel (3 October 2000)
- Jason S. Priebe sent me patches that changed the way curl issues HTTP
  requests. The entire request is now issued in one single shot. It didn't do
  this previously, and it has turned out that since the common browsers do it
  this way, some sites have turned out to work with browsers but not with
  curl! Although this is not a client-side problem, we want to be able to
  fully emulate browsers, and thus we have now adjusted the networking layer
  to slightly more appear as a browser. I adjusted Jason's patch, the faults
  are probably mine.

Daniel (2 October 2000)
- Anyone who ever uploaded data with curl on a slow link has noticed that the
  progess meter is updated very infrequently. That is due to the large buffer
  size curl is using. It reads 50Kb and sends it, updates the progress meter
  and loops. 50Kb is very much on a slow link, although it is pretty neat to
  use on a fast one.

  I've now made an adjustment that makes curl use a 2Kb buffer for uploads to
  start with. If curl's average upload speed is faster than buffer size bytes
  per second, curl will increase the used buffer size up to max 50Kb. It
  should make the progress meter work better.
  
Version 7.4 pre1

Daniel (29 September 2000)
- Ripped out the -w stuff from the library and put in the curl tool. It gets
  all the relevant info from the library using the new curl_easy_getinfo()
  function.

- brad at openbsd.org mailed me a patch that corrected my kerberos mistake and
  removed a compiler warning from hostip.c that OpenBSD people get.

Daniel (28 September 2000)
- Of course (I should probably get punished somehow) I didn't properly correct
  the #include lines for the base64 stuff in the kerberos sources in the just
  released 7.3 package. They still include the *_krb.h files! Now, the error
  is sooo very easy to spot and fix so I won't bother with a quick bug fix
  release. I'll post a patch whenever one is needed instead. It'll be
  available in the CVS in a few minutes anyway.

Version 7.3

Daniel (28 September 2000)
- Removed the base64_krb.[ch] files. They've now replaced the former
  base64.[ch] files.

Daniel (26 September 2000)
- Updated some docs.

- I changed the OpenSSL fix to work with older versions as well. The posted
  patch was only working with 0.9.6 and no older ones.
  
Version 7.3-pre8

Daniel (25 September 2000)
- Erdmut Pfeifer informed us that curl didn't build with OpenSSL 0.9.6 and
  showed us what needed to get patched in order to make it build properly
  again.

- Dirk Kruschewski found a bug in the cookie parser. I made an alternative
  approach to the solution Dirk himself suggested. The bug made a cookie
  header that didn't end with a trailing semicolon to not get parsed.

- I've marked -c and -t deprecated now. If you use any of them, curl will tell
  you to use "-C -" or "-T -" instead. I don't think occupying two letters for
  nearly identical functions is good use. Also, -T - kind of follows the curl
  tradition of using - for stdin where a file name is expected.

Daniel (23 September 2000)
- Martin Hedenfalk provided the patch that finally made the krb4 ftp upload
  work!

Daniel (21 September 2000)
- The kerberos code is not quite thread-safe yet. There are a few more globals
  that need to be take care of. Let's get the upload working first!

Daniel (20 September 2000)
- Richard Prescott solved another name lookup buffer size problem. I took this
  opportunity to rewrite the GetHost() function. With these large buffer
  sizes, I think keeping them as local arrays quickly turn ugly. I now use
  malloc() to get the buffer memory. Thanks to this, I now can realloc() to a
  large buffer in case of demand (errno == ERANGE) in case a solution like
  that would become necessary. I still want to avoid that kind of nastiness.

- Tried to compile and run curl on Linux for alpha and FreeBSD for alpha. Went
  as smooth as it could.

- Added a docs/examples directory with two tiny example sources that show how
  to use libcurl. I hope users will supply me with more useful examples
  further on.

- Applied a patch by Jörn Hartroth to no longer use the word 'inteface' in the
  config struct in the src/main.c file since certain compilers have that word
  "reservered".  I figure that is some kind of C++ decease.

- Updated the curl.1 man page with --interface and --krb4.

- Modified the base64Encode() function to work like the kerberos one, so that
  I could remove the use of that. There is no need for *two* base64 encoding
  functions! ;-)

Version 7.3pre5

Daniel (19 September 2000)
- The kerberos4-layer source code that is much "influenced" by the original
  krb4 source code, through yafc into curl, was using quite a lot of global
  variables. libcurl can't work properly with globals like that why I had to
  clean up almost every function in the new security.c to make them use
  connection specific variables instead of the globals. I just hope I didn't
  destroy anything now... :-) configure updated, version string now reflects
  krb4 built-in. It almost works now. Only uploads are still being naughty.

Version 7.3pre3

Daniel (18 September 2000)
- Martin Hedenfalk supplied a major patch that introduces krb4-ftp support to
  curl. Martin is the primary author of the ftp client named yafc and he did
  not hesitate to help us implement this when I asked him. Many and sincere
  thanks to a splendid effort. It didn't even take many hours!

- Stephen Kick supplied a big patch that introduces the --interface flag to
  the curl tool and CURLOPT_INTERFACE for libcurl. It allows you to specify an
  outgoing interface to use for your request. This may not work on all
  platforms. This needs testing.

- Richard Prescott noticed that curl on Tru64 unix could core dumped if the
  name didn't resolve properly. This was due to the GetHost() function not
  returning an error even though it failed on some platforms!

Daniel (15 September 2000)
- Updated all sorts of documents in regards to the new proxytunnel support.

Version 7.3pre2

Daniel (15 September 2000)
- Kai-Uwe Rommel pointed out a problem in the httpproxytunnel stuff for ftp.
  Adjusted it. Added better info message when setting up the tunnel and the
  pasv message when doing the second connect.
  
Version 7.3pre1

Daniel (15 September 2000)
- libcurl now allows "httpproxytunnel" to an arbitrary host and port name. The
  second connection on ftp needed that.

- TheArtOfHTTPScripting was corrected all over. I both type and spell really
  bad at times!
  
Daniel (14 September 2000)
- -p/--proxytunnel was added to 'curl'. It uses the new
  CURLOPT_HTTPPROXYTUNNEL libcurl option that allows "any" protocol to tunnel
  through the specified http proxy. At the moment, this should work with ftp.

Daniel (13 September 2000)
- Jochen Schaeuble found that file:// didn't work as expected. Corrected this
  and mailed the patch to the mailing list.

Daniel (7 September 2000)
- I changed the #define T() in curl.h since it turned out it wasn't really
  a good symbol to use (when you compiled PHP with curl as a module, that
  define collided with some IMAP define or something). This was posted to the
  PHP bug tracker.

- I added extern "C" stuff in two header files to better allow libcurl usage
  in C++ sorces. Discussions on the libcurl list with Danny Horswell lead to
  this.

Version 7.2.1

Daniel (31 August 2000)
- Albert Chin-A-Young fixed the configure script *again* and now it seems to
  detect Linux name resolving properly! (heard that before?)

- Troels Walsted Hansen pointed out that downloading a file containing the
  letter '+' from an ftp server didn't work. It did work from HTTP though and
  the reason was my lame URL decoder.

- I happened to notice that -I didn't at all work on ftp anymore. I corrected
  that.

Version 7.2

Daniel (30 August 2000)
- Understanding AIX is a hard task. I believe I'll never figure out why they
  solve things so differently from the other unixes. Now, I'm left with the
  AIX 4.3 run-time warnings about duplicate symbols that according to this
  article (http://www.geocrawler.com/archives/3/405/1999/9/0/2593428/) is a
  libtool flaw. I tried the mentioned patch, although that stops the linking
  completely.

  So, if I select to ignore the ld warnings there are compiler warnings that
  fill the screen pretty bad when curl compiles. It turns out that if I want
  to '#include <arpa/inet.h>', I can get tid of the warnings by include the
  following three include files before that one:

        #include <net/if_dl.h>
        #include <sys/mbuf.h>
        #include <netinet/if_ether.h>

  Now, is it really sane to add those include files before arpa/inet.h in all
  the source files that include it?

  Thanks to Albert Chin-A-Young at thewrittenword.com who gave me the AIX
  login to try everything on.

Daniel (24 August 2000)
- Jan Schmidt supplied us a new VC6 makefile for Windows as the previous one
  was not up to date but lacked several object files.

- More work on the naming.

- Albert Chin-A-Young provided a configure-check for large file support, as
  some systems seem to need that for them to work. Had to change the position
  for the config.h include file in every .c file in the libcurl dir...

- As suggested on the mailing list (by Troy Engel), I did use a --data-binary
  option instead of the messy way I've left described below. It seems to
  work. The libcurl fix remained the same as yesterday.

Daniel (23 August 2000)
- Back on the -d stripping newlines thing. The 'plain post' thing was added
  when I had no thought of that one could actually post binary data with
  it. Now, I have to add this functionality in a graceful manner and I think
  I've managed to come up with a way: '-d @file;binary' will thus post the
  file binary, exactly as its contents are. It is implemented with a new
  *setopt() option (CURLOPT_POSTFIELDSIZE) to set the postfield size, since
  libcurl can't strlen() the data in these cases.

- Albert Chin-A-Young made some very serious efforts and all the name
  resolving problems seem to have been sorted out now on all the platforms
  that previously showed them. I'll make another release now anyday because of
  this.

- The FAQ was much enhanced when it comes to the licensing issues thanks to
  Bjorn Reese.

Daniel (21 August 2000)
- Rick Welykochy pointed out a problem when you use -d to post and you want to
  keep the newlines, as curl strips them off as a bonus before posting...
  This needs to be addressed.

Version 7.1.1

Daniel (21 August 2000)
- Got more people involved in the gethostbyname_r() mess. Caolan McNamara sent
  me configure-code that turned out to be very similar to my existing tests
  which only make me more sure I'm on the right path. I changed the order of
  the tests slightly, as it seems that some compilers don't yell error if a
  function is used with too many parameters. Thus, the first tested function
  will seem ok... Let's hope more compilers think of too-few parameters as bad
  manners, as we're now trying the functions in that order; fewer first. I
  should also add that Lars Hecking mailed me and volunteered to run tests on
  a few odd systems. Coalan is keeping his work over at
  http://www.csn.ul.ie/~caolan/publink/gethostbyname_r/. Might be handy in the
  future as well.

Daniel (18 August 2000)
- I noticed I hadn't increased the name lookup buffer in lib/ftp.c. I don't
  think this is the reason for the continued trouble though.
