- 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.

committed
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.

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.
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
- 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.
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.

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.

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.
- 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

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
- 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

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.

- 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.

- 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.
