CHANGES

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.

Daniel (17 August 2000)
- Fred Noz corrected my stupid mistakes in the gethostbyname_r() fluff. It
  should affect some AIX, Digital Unix and HPUX 10 systems.

Daniel (15 August 2000)
- Mathieu Legare compiled and build 7.1 without errors on both AIX 4.2 as well
  as AIX 4.3. Now why did problems occur before?

- Fred Noz reported a -w/--write-out bug that caused it to malfunction when
  used combined with multiple URL retrievales. All but the first display got
  screwed up!

Daniel (11 August 2000)
- Jason Priebe and an anonymous friend found some host names the Linux version
  of curl could not resolve. It turned out the buffer used to retrieve that
  information was too small. Fixed. One could argue about the usefulness of
  not having the slightest trace of a man page for gethostbyname_r() on my
  Linux Redhat installation...

Daniel (10 August 2000)
- Balaji S Rao was first in line to note the missing possibility to replace
  the Content-Type: and Content-Length: headers when doing -d posts. I added
  the possibility just now. It seems some people wants to do standard posts
  using custom Content-Types.

Daniel (8 August 2000)
- Mike Dowell correctly discovered that curl did not approve of URLs with no
  user name but password. As in 'http://:foo@haxx.se'. I corrected this.

Version 7.1

Daniel (7 August 2000)
- My AIX 4 fix does not work. I need help from a AIX 4 hacker.

- I added my new document in the docs directory. It is aimed to become a sort
  of tutorial on how to do HTTP scripting with curl.

Daniel (4 August 2000)
- Working with Rich Gray on compiling curl for lots of different platforms.
  My fix for AIX 3.2 was not good enough and was slightly changed, I had to
  move an include file before another, as is now described in the source.

  AIX 4.2 (4.X?) has different gethostbyname_r() and gethostbyaddr_r()
  functions that the configure script didn't check for and thus the compile
  broke with an error. I have now changed the gethostbyname_r() check in the
  configure file to support all three versions of both these functions. My
  implementation that uses the AIX-style is though not yet verified and I may
  get problems to fix it if it turns out to bug since I don't have access to
  any system using that.

  For problems like that, I made the configure script allow --disable-thread
  to completely switch off the check for threadsafe versions of a few
  functions and thus go with the "good old versions" that tend to work
  although will break thread-safeness for libcurl. Most people won't use
  libcurl for other things than curl though, and curl doesn't need a
  thread-safe lib.

- Working on my big tutorial about HTTP scripting with curl.

Daniel (1 August 2000)
- Rich Gray spotted a problem in src/setup.h caused by a #define strequal()
  that was just a left-over from passed times. The strequal() is now a true
  function supplied by libcurl for a portable case insensitive string
  comparison. I added the prototypes in include/curl.h and removed the
  now obsolete #define.

- Igor Khristophorov made a fix to allow resumed download from Sun's
  JavaWebServer/1.1.1. It seems that their server sends bad Content-Range
  headers.

- The makefiles forced a static library build, which is bad since we now use
  libtool and thus have excellent shared library support! Albert Chin-A-Young
  found out.

Version 7.0.11beta

Daniel (1 August 2000)
- Albert Chin-A-Young pointed out that 'make install' did not properly create
  the header include directory, why it failed to install the header files as
  it should. Automake isn't really equipped to deal with subdirectories
  without Makefiles in any nice way. I had to run ahead and add Makefiles in
  both include and include/curl before I managed to create a top-level
  makefile that succeeds in install everything properly!

- Ok, no more "features" added now. Let's just verify that there's no major
  flaws added now.

Daniel (31 July 2000)
- Both Jeff Schasny and Ketil Froyn asked me how to tell curl not to send one
  of those internally generated headers. They didn't settle with the blank
  ones you could tell curl to use. I rewrote the header-replace stuff a
  little. Now, if you replace an internal header with your own and that new
  one is a blank header you will only remove the internal one and not get any
  blank. I couldn't figure out any case when you want that blank header.

Daniel (29 July 2000)
- It struck me that the lib used localtime() which is not thread-safe, so now
  I use localtime_r() in the systems that has it.

- I went through this entire document and removed all email addresses and left
  names only. I've really made an effort to always note who brought be bug
  reports or fixes, but more and more people ask me to remove the email
  addresses since they become victims for spams this way. Gordon Beaton got me
  working on this.

Daniel (27 July 2000)
- Jörn Hartroth found out that when you specified a HTTP proxy in an
  environment variable and used -L, curl failed in the second fetch. I
  corrected this problem and posted a patch to the list. No need for an extra
  beta release just for this.

Version 7.0.10beta

Daniel (27 July 2000)
- So, libtool replaced two of my files with symbolic links and I forgot to add
  the two new libtool files to the release archive (and they were added as
  symlinks as well!) This of course lead to that the configure script failed
  on 7.0.9...

Version 7.0.9beta

Daniel (25 July 2000)
- Kristian Köhntopp <kris at koehntopp.de> brought a fix that makes libcurl
  libtoolified, just as we've wanted for a while now. He also made the
  recently added man pages get installed properly on 'make install' and some
  other nice cleanups.

- In a discussion with Eetu Ojanen it struck me that if we use curl to get a
  page using a password, and that page then sends a Location: to another
  server that curl follows, curl will send the user name and password to that
  server as well.

  Now, I'll never be able to make curl do Location: following all that perfect
  and you're all sooner or later required to write a script to do several
  fetches when you're doing advanced stuff, but now I've modified curl to at
  least *only* send the user name and password to the original server. Which
  means that if get a page from server A with a password, that forwards curl
  to server B, curl won't use the password there. If server B then forwards
  curl back to server A again, the password will be used again.

  This is not a perfect implementation, as in a browser case it would only use
  the password if the left-prefix of the first path is the same. I just think
  that this fix prevents a somewhat lurky "security hole".

  As a side-note in this subject: HTTP passwords are sent in cleartext and
  will never be considered to be safe or secure. Use HTTPS for that.

- As discussed on the mailing list, I converted the FTP response reading
  function into using select() which then allows timeouts (even under win32!)
  if the command-reply session gets too slow or dies completely. I made a
  default timeout on 3600 seconds unless anything else is specified, since I
  don't think anyone wants to wait more than that for a single character to
  get received...

- Torsten Foertsch <torsten.foertsch at gmx.net> brought a set of fixes for
  the rfc1867 form posts. He introduced 'name=<file' which brings a means to
  suuply very large text chunks read from the given file name. It differs from
  'name=@file' in the way that this latter thing is marked in the uploaded
  contents as a file upload, while the first is just text (as in a input or
  textarea field). Torsten also corrected a bug that would happen if you used
  %s or similar in a -F file name.

- As discovered by Nico Baggus <Nico.Baggus at mail.ing.nl>, when transferring
  files to/from FTP using type ASCII curl should not expect the transfer to be
  the exact size reported by the server as the file size. Since ASCII may very
  well mean that the content is translated while transfered, the final size
  may very well differ. Therefor, curl now ignores the file size when doing
  ASCII transfers in FTP.

Daniel (24 July 2000)
- Added CURLOPT_PROXYPORT to the curl_easy_setopt() call to allow the proxy
  port number to be set separately from the proxy host name.

- Andrew <andrew at ugh.net.au> pointed out a netrc manual bug.

- The FTP transfer code now accepts a 250-code as well as the previously
  accepted 226, after a successful file transfer. Mohan <mnair at
  evergreen-funds.com> pointed this out.

- The check for *both* nsl and socket was never added in the v7 configure.in
  when I moved the main branch. I re-added that check to configure.in. This was
  discovered by Rich Gray.

- Howard, Blaise <Blaise.Howard at factiva.com> pointed out a missing free() in
  curl_disconnect() which of course meant libcurl ate memory.

- Brian E. Gallew noted that the HTTP 'Host:' header curl sent did not
  properly include the port number if non-default ports were used. This should
  now have been fixed.

- HTTP connect errors now return errors earlier. This was most notably causing
  problems when the HTTPS certificate had problems and later caused a crash.
  Many thanks to Gregory Nicholls <gnicholls at level8.com> for discovering
  and suggesting a fix...

Daniel (21 June 2000)
- After a "bug report" I received where the user was using both -F and -I in a
  HTTP request (it severly confused the library I should add), I added some
  checks to src/main.c that prevents setting more than one HTTP request
  command, no matter what the user wants! ;-)

Version 7.0.8beta

Daniel (20 June 2000)
- I did a major replace in many files to use the new curl domain haxx.se
  instead of the previous one.

- As Eetu Ojanen suggested, I finally took the step and now libcurl no longer
  makes a POST after it has followed a location. When the initial POST has
  been done, it'll turned into a GET for the further requests. This is only
  interesting when using -L/--location *and* doing a POST at the same time.

  While messing with this, I added another weird feature I call 'auto
  referer'. If you append ';auto' to the right of a given referer string (or
  only use that string as referer), libcurl will automatically set the
  previoud URL as refered when it follows a Location: and gets a succeeding
  document.

- My hero Rich Gray found the very obscure FTP bug that happened to him only
  when passing through a particular firewall and using the PORT command. It
  turned out that PORT was the only command in the lib/ftp.c source that
  didn't send a proper \r\n sequence but instead used the faulty \n which as
  it seemed is supported by most major ftp servers... :-O

Version 7.0.7beta

Daniel (16 June 2000)
- I had avoided this long enough now, so I moved the alternative progress bar
  stuff from the lib and added it to the client code. This is now using the
  recently added progress callback and it seems to work pretty much like
  before. Since it is only one progress bar and you and download and upload at
  the same time, this bar shows the combined progress of both directions. This
  code was just ported from the old place to this, Lars is still our saviour!
  ;-) This also made the documentation more accurate since I never removed
  this function from any docs! Although I now removed the CURLOPT_PROGRESSMODE
  from the library since the lib has only one internal progress meter and it
  will never get another. It is although likely that the internal one also
  will be moved to the client code in the future (when I have other means of
  getting the writeout data and move that too to the client).

- I took the opportunity to verify that standard progress meter works and I
  found out it didn't get inited properly. Grrr. I corrected that as well.

Daniel (15 June 2000)
- I thought I'd better verify that the -F option still works in v7 and of
  course it didn't... :-/ Anyway, I had the problems I could discover
  corrected. About one month of beta testing and not a single person has used
  this feature with v7?

- Björn correctly pointed out that the --progress-bar still doesn't work in
  v7. Hm.

Daniel (14 June 2000)
- Tim Tassonis discovered that curl 7 didn't handle normal http POST as it
  should. I corrected this.

Version 7.0.6beta

Daniel (14 June 2000)
- Björn Stenberg pointed out several problems (related to win32 compiling):
  lib/strequal.c had a bad #ifdef for one of the string comparisons (win32)
  src/main.c had several minor problems
  lib/makefile.m32 had getpass.[co] twice
  src/config-win32.h lacked the HAVE_FCNTL_H define
  both config-win32.h files now only set the HAVE_UNISTD_H define if the
  define MINGW32 is set, and I modified src/makefile.m32 and lib/makefile.m32
  to set it.

Version 7.0.5beta

Daniel (14 June 2000)
- Applied Luong Dinh Dung's comments about a few win32 compile problems.

- Applied Björn Stenberg's suggested fix that turns the win32 stdout to
  binary. It won't do it if the -B / --use-ascii option is used. That option
  is now an extended version of the previous -B /--ftp--ascii. The flag was
  already in use be the ldap as well so the new name fits pretty good. The
  libcyrl CURLOPT_TRANSFERTEXT was also introduced as an alias to the now
  obsolete CURLOPT_FTPASCII. Can't verify this fix myself as I have no win32
  compiler around.

Daniel (13 June 2000)
- Luong Dinh Dung <dung at sch.bme.hu> found a problem in curl_easy_cleanup()
  since it free()ed the main curl struct *twice*. This is now corrected.

Daniel (9 June 2000)
- Updated the RESOURCES file, added a README.win32 file.

Daniel (8 June 2000)
- So I finally added the progress callback to the *setopt() options and it
  should work now. I don't have the energy to write any test program for it
  right now.
- Made the callback function typedefs public in curl/curl.h for comfort. Just
  in case anyone wanna fiddle with such pointers.
- Updated the curl_easy_setopt() man page accordingly.

Version 7.0.4beta

Daniel (2 June 2000)
- I noticed that when doing Location: following, we lost custom headers in all
  but the first request.
- Removed the 'HttpPost' struct and moved the header stuff to the more generic
  curl_slist.
- Added some better slist-cleanups in src/main.c

Version 7.0.3beta

Daniel (31 May 2000)
- So I discovered that I released the 7.0.2beta without it being able to
  compile under Linux. gethostbyname_r() and gethostbyaddr_r() turned out to
  feature a different amount of arguments on different systems so I had to add
  a configure check for this and adjust the code slightly.

Version 7.0.2beta

Daniel (29 May 2000)
- Corrected the bits.* assignments when using CURLOPT options that only
  toggles one of those bits.

- Applied the huge patches from David LeBlanc <dleblanc at qnx.com> that add
  usage of the gethostbyname_r() and similar functions in case they're around,
  since that make libcurl much better threadsafe in many systems (such as
  solaris). I added the checks for these functions to the configure script.

  I can't explain why, but the inet_ntoa_r() function did not appear in my
  Solaris include files, I had to add my own include file for this for now.

Daniel (22 May 2000)
- Jörn Hartroth brought me fixes to make the win32 version compile properly as
