CHANGES.0

  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
  well as a rename of the 'interface' field in the urldata struct, as it seems
  to be reserved in some gcc versions!

- Rich Gray struck back with yet some portability reports. Data General DG/UX
  needed a little fix in lib/ldap.c since it doesn't have RTLD_GLOBAL defined.
  More fixes are expected as a result of Richies very helpful work.

Version 7.0.1beta

Daniel (21 May 2000)
- Updated lots of #defines, enums and variable type names in the library. No
  more weird URG or URLTAG prefixes. All types and names should be curl-
  prefixed to avoid name space clashes. The FLAGS-parameter to the former
  curl_urlget() has been converted into a bunch of flags to use in separate
  setopt calls. I'm still focusing on the easy-interface, as the curl tool is
  now using that.

- Bjorn Reese has provided me with an asynchronous name resolver that I plan
  to use in upcoming versions of curl to be able to gracefully timeout name
  lookups.

Version 7.0beta

Daniel (18 May 2000)
- Introduced LIBCURL_VERSION_NUM to the curl.h include file to better allow
  source codes to be dependent on the lib version. This define is now set to
  a dexadecimal number, with 8 bits each for major number, minor number and
  patch number. In other words, version 1.2.3 would make it 0x010203. It also
  makes a larger number a newer version.

Daniel (17 May 2000)
- Martin Kammerhofer correctly pointed out several flaws in the FTP range
  option. I corrected them.
- Removed the win32 winsock init crap from the lib to the src/main.c file
  in the application instead. They can't be in the lib, especially not for
  multithreaded purposes.

Daniel (16 May 2000)
- Rewrote the src/main.c source to use the new easy-interface to libcurl 7.
  There is still more work to do, but the first step is now taken.
  <curl/easy.h> is the include file to use.

Daniel (14 May 2000)
- FTP URLs are now treated slightly different, more according to RFC 1738.
- FTP sessions are now performed differently, with CWD commands to change
  directory instead of RETR/STOR/LIST with the full path. Discussions with
  Rich Gray made me notice these problems.
- Janne Johansson discovered and corrected a buffer overflow in the
  src/usrglob.c file.
- I had to add a lib/strequal.c file for doing case insensitive string
  compares on all platforms.

Daniel (8 May 2000):
- Been working lots on the new lib.
- Together with Rich Gray, I've tried to adjust the configure script to work
  better on the NCR MP-RAS Unix.

Daniel (2 May 2000):
- Albert Chin-A-Young pointed out that I had a few too many instructions in
  configure.in that didn't do any good.

Daniel (24 April 2000):
- Added a new paragraph to the FAQ about what to do when configure can't
  find OpenSSL even though it is installed. Supplied by Bob Allison

Daniel (12 April 2000):
- Started messing around big-time to convert the old library interface to a
  better one...

Daniel (8 April 2000):
- Made the progress bar look better for file sizes between 9999 kilobytes
  and 100 megabytes. They're now displayed XX.XM.
- I also noticed that ftp fetches through HTTP proxies didn't add the user
  agent string. It does now.
- Habibie <habibie at MailandNews.com> supplied a pretty good way to build RPMs
  on a Linux machine. It still a) requires me to be root to do it, b) leaves
  the rpm packages laying at some odd place on my disk c) doesn't work to
  build the ssl version of curl since I didn't install openssl from an rpm
  package so now the rpm crap thinks I don't have openssl and refuses to build
  a package that depends on ssl... Did I mention I don't get along with RPM?
- Once again I received a bug report about autoconf not setting -L prior to -l
  on the command line when checking for libs. In this case it made the native
  cc compiler on Solaris 7 to fail the OpenSSL check. This has previously been
  reported to cause problems on HP-UX and is a known flaw in autoconf 2.13. It
  is a pity there's no newer release around...

Daniel (4 April 2000):
- Marco G. Salvagno supplied me with two fixes that
  appearantly makes the OS/2 port work better with multiple URLs.

Daniel (2 April 2000):
- Another Location: fix. This time, when curl connected to a port and then
  followed a location with an absolute URL to another port, it misbehaved.

Daniel (27 March 2000):
- H. Daphne Luong pointed out that curl was wrongly
  messing up the proxy string when fetching a document through a http proxy,
  which screwed up multiple fetches such as in location: followings.

Daniel (23 March 2000):
- Marco G. Salvagno corrected my badly applied patch he
  actually already told me about!

- H. Daphne Luong brought me a fix that now makes curl
  ignore select() errors in the download if errno is EINTR, which turns out to
  happen every now and then when using libcurl multi-threaded...

Daniel (22 March 2000):
- Wham Bang supplied a couple of win32 fixes. HAVE_UNAME
  was accidentally #defined in config-win32.h, which it shouldn't have been.
  The HAVE_UNISTD_H is not defined when compiling with the Makefile.vc6
  makefile for MS VC++.

Daniel (21 March 2000):
- I removed the AC_PROG_INSTALL macro from configure.in, since it appears that
  one of the AM_* macros searches for a BSD compatible install already. Janne
  Johansson made me aware of this.

Version 6.5.2

Daniel (21 March 2000):
- Paul Harrington quickly pointed out to me that 6.5.1
  crashes hard. I upload 6.5.2 now as quickly as possible! The problem was
  the -D adjustments in src/main.c.

Version 6.5.1

Daniel (20 March 2000):
- An anonymous post on sourceforge correctly pointed out a possible buffer
  overflow in the curl_unescape() function for URL conversions. The main
  problem with this bug is that the ftp download uses that function and this
  single- byte overflow could lead to very odd bugs (as one reported by Janne
  Johansson).

Daniel (19 March 2000):
- Marco G. Salvagno supplied me with a series of patches
  that now allows curl to get compiled on OS/2. It even includes a section in
  the INSTALL file. Very nice job!

Daniel (17 March 2000):
- Wham Bang supplied a patch for the lib/Makefile.vc6
  file. We still need some fixes for the config-win32.h since it appears that
  VC++ and mingw32 have different opinions about (at least) unistd.h's
  existence.

Daniel (15 March 2000):
- I modified the -D/--dump-header workings so that it doesn't write anything
  to the file until it needs to. This way, you can actually use -b and -D
  on the same file if you want repeated invokes to store and read the cookies
  in that one single file.

- Poked around in lots of texts. Added the BUGS file for bug reporting stuff.
  Added the classic HTTP POST question to the FAQ, removed some #ifdef WIN32
  stuff from the sources (they're covered by the config-win32.h now).

- Pascal Gaudette fixed a missing ldap.c problem in the
  Makefile.vc6 file. He also addressed a problem in src/config-win32.h.

Daniel (14 March 2000):
- Paul Harrington pointed out that the 'http_code' variable in the -w output
  was never written. I fixed it now.

- Janne Johansson reported the complaints that OpenBSD does
  when getdate.c #includes malloc.h. It claims stdlib.h should be included
  instead. I added #ifdef HAVE_MALLOC_H code in getdate.y and two checks in
  the configure.in for malloc.h and stdlib.h.

Version 6.5

Daniel (13 March 2000):
- <curl at spam.wolvesbane.net> pointed out that the way curl sent cookies in a
  single line wasn't enjoyed by IIS4.0 servers. In my view, that is not what
  the standards say, but I added a white space between the name/value pairs to
  perhaps make them work better.

- Added the perl check back in the configure.in again since the mkhelp.pl
  script needs it!

- Made some beautifications in the curl man page.

Daniel (3 March 2000):
- Jörn helped me update the config-win32.h files with HAVE_SETVBUF and
  HAVE_STRDUP.

Daniel (3 March 2000):
- Uploaded the 6.5pre2 package.

Daniel (2 March 2000):
- Removed the perl-programs from the distribution, they never made many people
  happy and I'll still keep them available on the web.

- Added the -w and -N stuff to the man page. Documented the new progress meter
  display in README.curl.

- Jörn Hartroth, Chris <cbayliss at csc.come> and Ulf
  Möller from the openssl development team helped bringing me the details for
  fixing an OpenSSL usage flaw. It became apparent when they released openssl
  0.9.5 since that barfed on curl's bad behavior (not seeding a random number
  thing).

- Yet another option: -N/--no-buffer disables buffering in the output stream.
  Probably most useful for very slow transfers when you really want to get
  every byte curl receives within some preferred time. Andrew <tmr at gci.net>
  suggested this.

- Damien Adant mailed me his fixes for making curl compile on Ultrix.

Daniel (24 February 2000):
- Applied Jörn Hartroth's fixes for config-win32.h and lib/Makefile.w32.

  I should also make a note here, if nothing else to myself, that when using
  the %-syntax for variables in DOS command prompts, you must use two %-
  letters for each one since that is an escape letter there! Maybe I should
  use another letter instead!

- Added more variables to -w:

  'http_code'
  'time_namelookup'
  'time_connect'
  'time_pretransfer'
  'url_effective'

- Made -w@filename read the syntax from a file and -w@- reads the syntax from
  stdin in the good old "standard" curl way.

Daniel (22 February 2000):
- Released a 6.5pre1 version to get some test and user feedback.

Daniel (21 February 2000):

- I added the -w/--write-out flag and some variables to go with it. -w is a
  single string, whatever you enter there will be written out when curl has
  completed a successful request. There are some variable substitutions and
  they are specified as '%{variable}' (without the quotes). Variables that
  exist as of this moment are:

        total_time     - total transfer time in seconds (with 2 decimals)
        size_download  - total downloaded amount of bytes
        size_upload    - total uploaded amount of bytes
        speed_download - the average speed of the entire download
        speed_upload   - the average speed of the entire upload

  I will of course add more variables, but I need input on these and others.

- It struck me that the -# progress bar will be hard to just apply on the new
  progress bar concept. I need some feedback on this before that'll get re-
  introduced! :-/

Daniel (16 February 2000):
- Jörn Hartroth brought me some fixes for the progress meter and I continued
  working on it. It seems to work for http download, http post, ftp download
  and ftp upload. It should be a pretty good test it works generally good.

- Still need to add the -# progress bar into the new style progress interface.

- Gonna have a go at my new output option parameter next.

Daniel (15 February 2000):
- The progress meter stuff is slowly taking place. There's more left before it
  is working ok and everything is tested, but we're reaching there. Slowly!

Daniel (11 February 2000):
- Paul Marquis fixed the config file parsing of curl to
  deal with any-length lines, removing the previous limit of 4K.

- Eetu Ojanen's suggestion of supporting the @-style for -b
  is implemented. Now -b@<filename> works as well as the old style. -b@- also
  similarly reads the cookies from stdin.

- Reminder: -D should not write to the file until it needs to, in the same way
  -o does. That would enable curl to use -b and -D on the same file...

- Ellis Pritchard made getdate.y work for MacOS X.

- Paul Harrington helped me out finding the crash in the
  cookie parser. He also pointed out curl's habit of sending empty cookies to
  the server.

Daniel (8 February 2000):
 - Ron Zapp corrected a problem in src/urlglob.c that
   prevented curl from getting compiled on sunos 4. The problem had to do
   with the difference in sprintf() return code types.

 - Transfer() should now be able to download and upload simultaneously. Let's
   do some progress meter fixes later this week.

Daniel (31 January 2000):
 - Paul Harrington found another core dump in the cookie
   parser. Curl doesn't properly recognize the 'version' keyword and I think
   that is what caused this. I need to refresh some specs on cookies and see
   what else curl lacks to improve this a bit more once and for all.

   RFC 2109 clearly specifies how cookies should be dealt with when they are
   compliant with that spec. I don't think many servers are though...

 - Mark W. Eichin found that while curl is uploading a form
   to a web site, it doesn't read incoming data why it'll hang after a while
   since the socket "pipe" becomes full.

   It took me two hours to rewrite Download() and Upload() into the new
   single function Transfer(). It even seems to work! More testing is required
   of course... I should get the header-sending together in a kind of queue
   and let them get "uploaded" in Transfer() as well.

 - Zhibiao Wu pointed out a curl bug in the location: area,
   although I did not get a reproducible way to do this why I have to wait
   with fixing anything.

 - Bob Schader suggested I should implement resume
   support for the HTTP PUT operation, and as I think it is a valid suggestion
   I'll work on it.

Daniel (25 January 2000):
 - M Travis Obenhaus pointed out a manual mixup with -y and -Y that was
   corrected.

 - Jens Schleusener pointed out a problem to compile
   curl on AIX 4.1.4 and gave me a solution. This problem was already fixed
   by Jörn's recent #include modifications!

Daniel (19 January 2000):
 - Oskar Liljeblad pointed out and corrected a problem
   in the Location: following system that made curl following a location: to a
   different protocol to fail.

   At January 31st I re-considered this fix and the surrounding source code. I
   could not really see that the patch did any difference, why I removed it
   again for further research and debugging. (It disabled location: following
   on server not running on default ports.)

 - Jörn Hartroth brought a fix that once again
   made it possible to select progress bar.

 - Jörn also fixed a few include problems.

Version 6.4

Daniel (17 January 2000):
 - Based on suggestions from Björn Stenberg, I made the
   progress deal better with larger files and added a "Time" field which shows
   the time spent on the download so far.
 - I'm now using the CVS repository on sourceforge.net, which also allows web
   browsing. See http://curl.haxx.nu.

Daniel (10 January 2000):
 - Renumbered some enums in curl/curl.h since tag number 35 was used twice!
 - Added "postquote" support to the ftp section that enables post-ftp-transfer
   quote commands.
 - Now made the -Q/--quote parameter recognize '-' as a prefix, which means
   that command will be issued AFTER a successful ftp transfer. This can of
   course be used to delete or rename a file after it has been uploaded or
   downloaded. Use your imagination! ;-)
 - Since I do the main development on solaris 2.6 now, I had to download and
   install GNU groff to generate the hugehelp.c file. The solaris nroff cores
   on the man page! So, in order to make the solaris configure script find a
   better result I made gnroff get checked prior to the regular nroff.
