- David Shaw finally removed all traces of Gopher and we are now officially
not supporting it. It hasn't been functioning for years anyway, so this is
just finally stating what already was true. And a cleanup at the same time.
- Bryan Henderson turned the 'initialized' variable for curl_global_init()
into a counter, and thus you can now do multiple curl_global_init() and you
are then supposed to do the same amount of calls to curl_global_cleanup().
Bryan has also updated the docs accordingly.
Daniel (13 January 2006)
- Andrew Benham fixed a race condition in the test suite that could cause the
test script to kill all processes in the current process group!
Daniel (12 January 2006)
- Michael Jahn:
Fixed FTP_SKIP_PASV_IP and FTP_USE_EPSV to "do right" when used on FTP thru
HTTP proxy.
Fixed PROXYTUNNEL to work fine when you do ftp through a proxy. It would
previously overwrite internal memory and cause unpredicted behaviour!
Daniel (11 January 2006)
- I decided to document the "secret option" here now, as I've received *NO*
feedback at all on my mailing list requests from November 2005:
18 years ago
I'm looking for feedback and comments. I added some experimental code the
other day, that allows a libcurl user to select what method libcurl should
use to reach a file on a FTP(S) server.
This functionality is available in CVS code and in recent daily snapshots.
Let me explain...
The current name for the option is CURLOPT_FTP_FILEMETHOD (--ftp-method for
the command line tool) and you set it to a long (there are currenly no
defines for the argument values, just plain numericals). You can set three
different "methods" that do this:
1 multicwd - like today, curl will do a single CWD operation for each path
part in the given URL. For deep hierarchies this means very many
commands. This is how RFC1738 says it should be done. This is the
2 nocwd - no CWD at all is done, curl will do SIZE, RETR, STOR etc and give
a full path to the server.
3 singlecwd - make one CWD with the full target directory and then operate
on the file "normally".
(With the command line tool you do --ftp-method [METHOD], where [METHOD] is
one of "multicwd", "nocwd" or "singlecwd".)
What feedback I'm interested in:
1 - Do they work at all? Do you find servers where one of these don't work?
2 - What would proper names for the option and its arguments be, if we
consider this feature good enough to get included and documented in
upcoming releases?
3 - Should we make libcurl able to "walk through" these options in case of
(path related) failures, or should it fail and let the user redo any
possible retries?
(This option is not documented in any man page just yet since I'm not sure
these names will be used or if the functionality will end up exactly like
this. And for the same reasons we have no test cases for these yet.)
Daniel (10 January 2006)
- When using a bad path over FTP, as in when libcurl couldn't CWD into all
given subdirs, libcurl would still "remember" the full path as if it is the
current directory libcurl is in so that the next curl_easy_perform() would
get really confused if it tried the same path again - as it would not issue
any CWD commands at all, assuming it is already in the "proper" dir.
Starting now, a failed CWD command sets a flag that prevents the path to be
"remembered" after returning.
Daniel (7 January 2006)
- Michael Jahn fixed so that the second CONNECT when doing FTP over a HTTP
proxy actually used a new connection and not sent the second request on the
first socket!

Daniel (6 January 2006)
- Alexander Lazic made the buildconf run the buildconf in the ares dir if that
is present instead of trying to mimic that script in curl's buildconf
Daniel (3 January 2006)
- Andres Garcia made the TFTP test server build with mingw.
Daniel (16 December 2005)
- Jean Jacques Drouin pointed out that you could only have a user name or
password of 127 bytes or less embedded in a URL, where actually the code
uses a 255 byte buffer for it! Modified now to use the full buffer size.
Daniel (12 December 2005)
- Dov Murik corrected the HTTP_ONLY define to disable the TFTP support properly
Version 7.15.1 (7 December 2005)
Daniel (6 December 2005)
- Full text here: Pointed out by
Stefan Esser.
libcurl's URL parser function can overflow a malloced buffer in two ways, if
given a too long URL.
These overflows happen if you
1 - pass in a URL with no protocol (like "http://") prefix, using no slash
and the string is 256 bytes or longer. This leads to a single zero byte
overflow of the malloced buffer.
2 - pass in a URL with only a question mark as separator (no slash) between
the host and the query part of the URL. This leads to a single zero byte
overflow of the malloced buffer.
Both overflows can be made with the same input string, leading to two single
zero byte overwrites.
The affected flaw cannot be triggered by a redirect, but the long URL must
be passed in "directly" to libcurl. It makes this a "local" problem. Of
course, lots of programs may still pass in user-provided URLs to libcurl
without doing much syntax checking of their own, allowing a user to exploit
this vulnerability.
There is no known exploit at the time of this writing.
Daniel (2 December 2005)
- Jamie Newton pointed out that libcurl's file:// code would close() a zero
file descriptor if given a non-existing file.
Daniel (24 November 2005)
- Doug Kaufman provided a set of patches to make curl build fine on DJGPP
again using configure.
- Yang Tse provided a whole series of patches to clear up compiler warnings on
Daniel (17 November 2005)
- I extended a patch from David Shaw to make libcurl _always_ provide an error
string in the given error buffer to address the flaw mention on 21 sep 2005.
Daniel (16 November 2005)
- Applied Albert Chin's patch that makes the libcurl.pc pkgconfig file get
installed on 'make install' time.
Daniel (14 November 2005)
- Quagmire reported that he needed to raise a NTLM buffer for SSPI to work
properly for a case, and so we did. We raised it even for non-SSPI builds
but it should not do any harm.
- Jan Kunder's debian bug report identified a weird
error message for when you try to upload a file and the requested directory
doesn't exist on the target server.
- Yang Tse fixed compiler warnings in lib/ssluse.c with OpenSSL 0.9.8 and in
lib/memdebug.h that showed up in his msvc builds.
Daniel (13 November 2005)
- Debian bug report 338681 by Jan Kunder: make curl better detect and report
bad limit-rate units: Now curl will return
error if a bad unit is used.
- Thanks to this nice summary of poll() implementations: and further tests by Eugene
Kotlyarov, we now know that cygwin's poll returns only POLLHUP on remote
connectin closure so we check for that case (too) and re-enable poll for
cygwin builds.
Daniel (12 November 2005)
- Eugene Kotlyarov found out that cygwin's poll() function isn't doing things
right: so we now disable
poll() and use select() on cygwin too (we already do the same choice on Mac
- Dima Barsky patched problem #1348930: the GnuTLS code completely ignored
client certificates! (
Daniel (10 November 2005)
- David Lang fixed IPv6 support for TFTP!
- Introducing range stepping to the curl globbing support. Now you can specify
step counter by adding :[num] within the brackets when specifying a range:
If no step counter is set, it defaults to 1 as before:
Daniel (8 November 2005)
- Removed the use of AI_CANONNAME in the IPv6-enabled resolver functions since
we really have no use for reverse lookups of the address.
I truly hope these are the last reverse lookups we had lingering in the
- Dmitry Bartsevich discovered some issues in compatibilty of SSPI-enabled
version of libcurl with different Windows versions. Current version of
libcurl imports SSPI functions from secur32.dll. However, under Windows NT
4.0 these functions are located in security.dll, under Windows 9x - in
secur32.dll and Windows 2000 and XP contains both these DLLs (security.dll
just forwards calls to secur32.dll).
Dmitry's patch loads proper library dynamically depending on Windows
version. Function InitSecurityInterface() is used to obtain pointers to all
of SSPI function in one structure.
Daniel (31 October 2005)
- Vilmos Nebehaj improved libcurl's LDAP abilities:
The LDAP code in libcurl can't handle LDAP servers of LDAPv3 nor binary
attributes in LDAP objects. So, I made a quick patch to address these
The solution is simple: if we connect to an LDAP server, first try LDAPv3
(which is the preferred protocol as of now) and then fall back to LDAPv2.
In case of binary attributes, we first convert them to base64, just like the
openldap client does. It uses ldap_get_values_len() instead of
ldap_get_values() to be able to retrieve binary attributes correctly. I
defined the necessary LDAP macros in lib/ldap.c to be able to compile
libcurl without the presence of libldap
Daniel (27 October 2005)
- Nis Jorgensen filed bug report #1338648
( which really is more of a
feature request, but anyway. It pointed out that --max-redirs did not allow
it to be set to 0, which then would return an error code on the first
Location: found. Based on Nis' patch, now libcurl supports CURLOPT_MAXREDIRS
set to 0, or -1 for infinity. Added test case 274 to verify.
- tommink[at] reported in bug report #1337723
( that curl could not upload
binary data from stdin on Windows if the data contained control-Z (hex 1a)
since that is treated as end-of-file when read in text mode. Gisle Vanem
pointed out the fix, and I made both -T and --data-binary take advantage of
- Jaz Fresh pointed out that if you used "-r [number]" as was wrongly described
in the man page, curl would send an invalid HTTP Range: header. The correct
way would be to use "-r [number]-" or even "-r -[number]". Starting now,
curl will warn if this is discovered, and automatically append a dash to the
range before passing it to libcurl.
Daniel (25 October 2005)
- Amol Pattekar reported a bug with great detail and a fine example in bug
#1326306 ( When using the multi
interface and connecting to a host with multiple IP addresses, and one of
the addresses fails to connect (the server must exist and respond, just not
accept connections) libcurl leaks a socket descriptor. Thanks to the fine
report, I could find and fix this.
Daniel (22 October 2005)
- Dima Barsky reported a problem with GnuTLS-enabled libcurl in bug report
#1334338 ( When reading an SSL
stream from a server and the server requests a "rehandshake", the current
code simply returns this as an error. I have no good way to test this, but
I've added a crude attempt of dealing with this situation slightly better -
it makes a blocking handshake if this happens. Done like this because fixing
this the "proper" way (that would handshake asynchronously) will require
quite some work and I really need a good way to test this to do such a
Daniel (21 October 2005)
- "Ofer" reported a problem when libcurl re-used a connection and failed to do
it, it could then accidentally actually crash. Presumably, this concerns FTP
- Temprimus improved the MSVC makefile so that the static debug SSL libs are
linked to the executable and not to the libcurld.lib
- Bradford Bruce made the windows resolver code properly return
errors (as documented).
Daniel (20 October 2005)
- Dave Dribin made libcurl understand and handle cases when the server
(wrongly) sends *two* WWW-Authenticate headers for Digest. While this should
never happen in a sane world, libcurl previously got into an infinite loop
when this occurred. Dave added test 273 to verify this.
- Temprimus improved the MSVC makefile: "makes a build option available so if
you set rtlibcfg=static for the make, then it would build with /MT. The
default behaviour is /MD (the original)."
Daniel (14 October 2005)
- Reverted the LIBCURL_VERSION_NUM change from October 6. As Dave Dribin
reported, the define is used by the configure script and is assumed to use
the 0xYYXXZZ format. This made "curl-config --vernum" fail in the 7.15.0
release version.

Version 7.15.0 (13 October 2005)
Daniel (12 October 2005)
- Michael Sutton of iDEFENSE reported and I fixed a securitfy flaw in the NTLM
code that would overflow a buffer if given a too long user name or domain
name. This would happen if you enable NTLM authentication and either
A - pass in a user name and domain name to libcurl that together are longer
than 192 bytes
B - allow (lib)curl to follow HTTP "redirects" (Location: and the
appropriate HTTP 30x response code) and the new URL contains a URL with
a user name and domain name that together are longer than 192 bytes
See for further details and updates
Daniel (5 October 2005)
- Darryl House reported a problem with using -z to download files from FTP.
It turned out that if the given time stamp was exact the same as the remote
time stamp, the file would still wrongly be downloaded. Added test case 272
to verify.
Daniel (4 October 2005)
- Domenico Andreoli fixed a man page malformat and removed odd (0xa0) bytes
from the configure script.
- Michael Wallner reported that the date parser had wrong offset stored for
the MEST and CEST time zones.
Daniel (27 September 2005)
- David Yan filed bug #1299181 (
that identified a silly problem with Content-Range: headers with the 'bytes'
keyword written in a different case than all lowercase! It would cause a
- TJ Saunders of the proftpd project identified and pointed out problems with
the modified FTPS negotiation change of August 19 2005. Thus, we revert the
change back to pre-7.14.1 status.
Daniel (21 September 2005)
- Fixed "cut off" sentence in the libcurl-tutorial man page:
- Clarified in the curl_easy_setopt man page what the default
- Clarified in the curl_easy_setopt man page that CURLOPT_ERRORBUFFER
sometimes doesn't fill in the buffer even though it is supposed to:
- When CURLE_URL_MALFORMAT is returned due to a missing URL, it now has an
error string set.
Daniel (19 September 2005)
- Dmitry Bartsevich made the SSPI support work on Windows 9x as well.

Daniel (15 September 2005)
- Added a TFTP server to the test suite and made the test suite capable of
using it.
Daniel (7 September 2005)
- Ben Madsen's detailed reports that funnily enough only occurred with certain
glibc versions turned out to be curl using an already closed file handle
during certain conditions (like when saving FTP server "headers").
- Scott Davis helped me track down a problem in the test HTTP server that made
test case 56 wrongly fail at times. It turned out it was due to the server
finding the end of a chunked-encoded POST too early.
Daniel (6 September 2005)
- Now curl warns if an unknown variable is used in the -w/--writeout argument.
Daniel (4 September 2005)
- I applied Nicolas Fran<61>ois' man page patch he posted to the Debian bug
tracker. It corrected two lines that started with apostrophes, which isn't
legal nroff format.
- Added --ftp-skip-pasv-ip to the command line tool, that sets the new
CURLOPT_FTP_SKIP_PASV_IP option. It makes libcurl re-use the control
connection's IP address when setting up the data connection instead of
extractting the IP address from the PASV response. It has turned out this
feature is frequently needed by people to circumvent silly servers and silly
firewalls, especially when FTPS is used and the PASV command-response is
sent encrtyped.

Daniel (1 September 2005)
- John Kelly added TFTP support to libcurl. A bunch of new error codes was
added. TODO: add them to docs. add TFTP server to test suite. add TFTP to
list of protocols whereever those are mentioned.
Version 7.14.1 (1 September 2005)
Daniel (29 August 2005)
- Kevin Lussier pointed out a problem with curllib.dsp and how to fix it.
- Igor Polyakov fixed a rather nasty problem with the threaded name resolver
for Windows, that could lead to an Access Violation when the multi interface
was used due to an issue with how the resolver thread was and was not
- Simon Josefsson brought a patch that allows curl to get built to use GNU GSS
instead of MIT/Heimdal for GSS capabilities.
Daniel (24 August 2005)
- Toby Peterson added CURLOPT_IGNORE_CONTENT_LENGTH to the library, accessible
from the command line tool with --ignore-content-length. This will make it
easier to download files from Apache 1.x (and similar) servers that are
still having problems serving files larger than 2 or 4 GB. When this option
is enabled, curl will simply have to wait for the server to close the
connection to signal end of transfer. I wrote test case 269 that runs a
simple test to verify that this works.
- (Trying hard to exclude emotions now.) valgrind version 3 suddenly renamed
the --logfile command line option to --log-file, and thus the test script
valgrind autodetection now has yet another version check to do and then it
alters the valgrind command line accordingly.
- Fixed CA cert verification using GnuTLS with the default bundle, which
previously failed due to GnuTLS not allowing x509 v1 CA certs by default.
Ralph Mitchell reported.
Daniel (19 August 2005)
- Norbert Novotny had problems with FTPS and he helped me work out a patch
that made curl run fine in his end. The key was to make sure we do the
SSL/TLS negotiation immediately after the TCP connect is done and not after
a few other commands have been sent like we did previously. I don't consider
this change necessary to obey the standards, I think this server is pickier
than what the specs allow it to be, but I can't see how this modified
libcurl code can add any problems to those who are interpreting the
standards more liberally.
Daniel (17 August 2005)
- Jeff Pohlmeyer found out that if you ask libcurl to load a cookiefile (with
CURLOPT_COOKIEFILE), add a cookie (with CURLOPT_COOKIELIST), tell it to
write the result to a given cookie jar and then never actually call
curl_easy_perform() - the given file(s) to read was never read but the
output file was written and thus it caused a "funny" result.
- While doing some tests for the bug above, I noticed that Firefox generates
large numbers (for the expire time) in the cookies.txt file and libcurl
didn't treat them properly. Now it does.

Daniel (15 August 2005)
- Added more verbose "warning" messages to the curl client for cases where it
fails to open/read files etc to help users diagnose why it doesn't do what
you'd expect it to. Converted lots of old messages to use the new generic
function I wrote for this purpose.
Daniel (13 August 2005)
- James Bursa identified a libcurl HTTP bug and a good way to repeat it. If a
site responds with bad HTTP response that doesn't contain any header at all,
only a response body, and the write callback returns 0 to abort the
transfer, it didn't have any real effect but the write callback would be
called once more anyway.
Daniel (12 August 2005)
- Based on Richard Clayton's reports, I found out that using curl -d @filename
when 'filename' was not possible to access made curl use a GET request
- The time condition illegal syntax warning is now inhibited if -s is used.
Daniel (10 August 2005)
- Mario Schroeder found out that one of the debug callbacks calls that regards
SSL data with the CURLINFO_TEXT type claimed that the data was one byte
larger than it actually is, thus falsely telling the application that the
terminating zero was part of the data.
Daniel (9 August 2005)
- Christopher R. Palmer fixed the offsets used for date parsings when the time
zone name of a daylight savings time was used. For example, PDT vs PDS. This
flaw was introduced with the new date parser (11 sep 2004 - 7.12.2).
Fortunately, no web server or cookie string etc should be using such time
zone names thus limiting the effect of this bug.
Daniel (8 August 2005)
- Jon Grubbs filed bug report #1249962
( which identified a problem
with NTLM on a HTTP proxy if an FTP URL was given. libcurl now properly
switches to pure HTTP internally when an HTTP proxy is used, even for FTP
URLs. The problem would also occur with other multi-pass auth methods.
Daniel (7 August 2005)
- When curl is built with GnuTLS, curl-config didn't include "SSL" when
--features was used.
Daniel (28 July 2005)
set to 1, CURLOPT_NOBODY will now automatically be set to 0.
Daniel (27 July 2005)
- Dan Fandrich changes over the last week: fixed numerous minor configure
option parsing flaws: --without-gnutls, --without-spnego --without-gssapi
and --without-krb4. Spellfixed several error messages.
- Peteris Krumins added CURLOPT_COOKIELIST and CURLINFO_COOKIELIST, which is a
simple interface to extracting and setting cookies in libcurl's internal
"cookie jar". See the new cookie_interface.c example code.
Daniel (13 July 2005)
- Diego Casorran provided patches to make curl build fine on Amiga again.
Daniel (12 July 2005)
- Adrian Schuur added trailer support in the chunked encoding stream. The
trailer is then sent to the normal header callback/stream. I wrote up test
case 266 to verify the basic functionality. Do note that test case 34
contains a flawed chunked encoding stream that still works the same.
Daniel (5 July 2005)
- Gisle Vanem came up with a nice little work-around for bug #1230118
( It seems the Windows (MSVC)
libc time functions may return data one hour off if TZ is not set and
automatic DST adjustment is enabled. This made curl_getdate() return wrong
value, and it also concerned internal cookie expirations etc.
Daniel (4 July 2005)
- Andrew Bushnell provided enough info for me to tell that we badly needed to
fix the CONNECT authentication code with multi-pass auth methods (such as
NTLM) as it didn't previously properly ignore response-bodies - in fact it
stopped reading after all response headers had been received. This could
lead to libcurl sending the next request and reading the body from the first
request as response to the second request. (I also renamed the function,
which wasn't strictly necessary but...)
The best fix would to once and for all make the CONNECT code use the
ordinary request sending/receiving code, treating it as any ordinary request
instead of the special-purpose function we have now. It should make it
better for multi-interface too. And possibly lead to less code...
Added test case 265 for this. It doesn't work as a _really_ good test case
since the test proxy is too stupid, but the test case helps when running the
debugger to verify.
Daniel (30 June 2005)
- Dan Fandrich improved the configure script's ability to figure out what kind
of strerror_r() API that is used when cross-compiling. If __GLIB__ is
defined, it assumes the glibc API. If not, it issues a notice as before that
the user needs to manually edit lib/config.h for this.

Daniel (23 June 2005)
- David Shaw's fix that unifies proxy string treatment so that a proxy given
with CURLOPT_PROXY can use a http:// prefix and user + password. The user
and password fields are now also URL decoded properly. Test case 264 added
to verify.
Daniel (22 June 2005)
- David Shaw updated libcurl.m4

Daniel (13 June 2005)
- Made buildconf run libtoolize in the ares dir too (inspired by Tupone's
reverted patch).
Daniel (9 June 2005)
- Incorporated Tupone's findtool fix in buildconf (slightly edited)
- Incorporated Tupone's head -n fix in buildconf.
Daniel (8 June 2005)
- Reverted Tupone's patch again, it broke numerous autobuilds. Let's apply it
in pieces, one by one and see what we need to adjust to work all over.
Daniel (6 June 2005)
- Tupone Alfredo fixed three problems in buildconf:
1) findtool does look per tool in PATH and think ./perl is the perl
executable, while is just a local directory (I have . in the PATH)
2) I got several warning for head -1 deprecated in favour of head -n 1
3) ares directory is missing some file (missing is missing :-) ) because
automake and friends is not run.
Daniel (3 June 2005)
- Added docs/libcurl/getinfo-times, based on feedback from 'Edi':
- Andres Garcia provided yet another text mode patch for several test cases so
that they do text comparisions better on Windows (newline-wise).
Daniel (1 June 2005)
- The configure check for c-ares now adds the cares lib before the other libs,
to make it build fine with mingw. Inspired by Tupone Alfredo's bug report
and patch:
Daniel (31 May 2005)
- Todd Kulesza reported a flaw in the proxy option, since a numerical IPv6
address was not possible to use. It is now, but requires it written
RFC2732-style, within brackets - which incidently is how you enter numerical
IPv6 addresses in URLs. Test case 263 added to verify.
Daniel (30 May 2005)
- Eric Cooper reported about a problem with HTTP servers that responds with
binary zeroes within the headers. They confused libcurl to do wrong so the
downloaded headers become incomplete. The fix is now verified with test case

Daniel (25 May 2005)
- Fixed problems with the test suite, and in particular the FTP test cases
since it previously was failing every now and then in a nonsense manner.
- --trace-time now outputs the full microsecond, all 6 digits.

Daniel (24 May 2005)
- Andres Garcia provided a text mode patch for several test cases so that they
do text comparisions better on Windows (newline-wise).
- Any 2xx response (and not just 200) is now considered a fine response to
TYPE, as some servers obviously sends a 226 there. Added test case 261 to
verify. Based on a question/report by Georg Wicherski.
Daniel (20 May 2005)
- Improved to allow stdout tests to be mode=text as well, just
as file comparisons already supports. Added this info to the FILEFORMAT
Daniel (18 May 2005)
- John McGowan identified a problem in bug report #1204435
( with malformed URLs like
"http://somehost?data" as it added a slash too much in the request ("GET
/?data/"...). Added test case 260 to verify.

- The configure check for strerror_r() failed to detect the proper API at
18 years ago
times, like on HP-UX 10.20. Then lib/strerror.c badly assumed the glibc
version if the posix define wasn't set (since it _had_ found a strerror_r).
Daniel (16 May 2005)
- The gmtime_r() function in HP-UX 10.20 is broken. About 13 test cases fail
due to this. There's now a configure check that attempts to detect the bad
function and not use it on such systems.

Version 7.14.0 (16 May 2005)
Daniel (13 May 2005)
- Grigory Entin reported that curl's configure detects a fine poll() for Mac
OS X 10.4 (while 10.3 or later detected a "bad" one), but the executable
doesn't work as good as if built without poll(). I've adjusted the configure
to always skip the fine-poll() test on Mac OS X (darwin).
Daniel (12 May 2005)
- When doing a second request (after a disconnect) using the same easy handle,
over a proxy that uses NTLM authentication, libcurl failed to use NTLM again
properly (the auth method was accidentally reset to the same as had been set
for host auth, which defaults to Basic). Bug report #1200661
( identified the the problem and
the fix.
- If -z/--time-cond is used with an invalid date syntax, this is no longer
silently discarded. Instead a proper warning message is diplayed that
informs about it. But it still continues without the condition.
Version 7.14.0-pre2 (11 May 2005)
Daniel (11 May 2005)
- Starting now, libcurl sends a little different set of headers in its default
HTTP requests:
A) Normal non-proxy HTTP:
- no more "Pragma: no-cache" (this only makes sense to proxies)
B) Non-CONNECT HTTP request over proxy:
- "Pragma: no-cache" is used (like before)
- "Proxy-Connection: Keep-alive" (for older style 1.0-proxies)
C) CONNECT HTTP request over proxy:
- "Host: [name]:[port]"
- "Proxy-Connection: Keep-alive"
The A) case is mostly to reduce the default header size and remove a
pointless header.
The B) is to address (rare) problems with HTTP 1.0 proxies
The C) headers are both to address (rare) problems with some proxies. The
code in libcurl that deals with CONNECT requests need a rewrite, but it
feels like a too big a job for me to do now. Details are added in the code
comments for now.
Updated a large amount of test cases to reflect the news.

- Half-baked attempt to bail out if select() returns _only_ errorfds when the
transfer is in progress. An attempt to fix Allan's problem. See and the rest of that thread
for details.
I'm still not sure this is the right fix, but...
Version 7.14.0-pre1 (9 May 2005)
Daniel (2 May 2005)
- Sort of "fixed" KNOWN_BUGS #4: curl now builds IPv6 enabled on AIX 4.3. At
least it should no longer cause a compiler error. However, it does not have
AI_NUMERICHOST so we cannot getaddrinfo() any numerical addresses with it
(we use that for FTP PORT/EPRT)! So, I modified the configure check that
checks if the getaddrinfo() is working, to use AI_NUMERICHOST since then
it'll fail on AIX 4.3 and it will automatically build with IPv6 support
- Added --trace-time that when used adds a time stamp to each trace line that
--trace, --trace-ascii and --verbose output. I also made the '>' display
separate each line on the linefeed so that HTTP requests etc look nicer in
the -v output.
- Made curl recognize the environment variables Lynx (and others?) support for
pointing out the CA cert path/file: SSL_CERT_DIR and SSL_CERT_FILE. If
CURL_CA_BUNDLE is not set, they are checked afterwards.
Like before: on windows if none of these are set, it checks for the ca cert
file like this:
1. application's directory
2. current working directory
3. Windows System directory (e.g. C:\windows\system32)
4. Windows Directory (e.g. C:\windows)
5. all directories along %PATH%

- The script now starts test servers by doing fork() and exec()
instead of the previous approach. This is less complicated and should
hopefully lead to less "leaked" servers (servers that aren't stopped
properly when the tests are stopped).
- Alexander Zhuravlev found a case when you did "curl -I [URL]" and it
complained on the chunked encoding, even though a HEAD should never return a
body and thus it cannot be a chunked-encoding problem!
Daniel (30 April 2005)
- Alexander Zhuravlev found out that (lib)curl SIGSEGVed when using
--interface on an address that can't be bound.

- Working on fixing up test cases to mark sections as 'mode=text' for things
that curl writes as text files, since then they can get different line
endings depending on OS. Andr<64>s Garc<72>a helps me work this out.
Did lots of other minor tweaks on the test scripts to work better and more
reliably find test servers and also kill test servers.
- Dan Fandrich pointed out how the script killed the HTTP server
instead of the HTTPS server when closing it down.
Daniel (27 April 2005)
- Paul Moore made curl check for the .curlrc file (_curlrc on windows) on two
more places. First, CURL_HOME is a new environment variable that is used
instead of HOME if it is set, to point out where the default config file
lives. If there's no config file in the dir pointed out by one of the
environment variables, the Windows version will instead check the same
directory the executable curl is located in.

Daniel (25 April 2005)
- Fred New reported a bug where we used Basic auth and user name and password
in .netrc, and when following a Location: the subsequent requests didn't
properly use the auth as found in the netrc file. Added test case 257 to
verify my fix.
- Based on feedback from Cory Nelson, I added some preprocessor magic in
*/setup.h and */config-win32.h to build fine with VS2005 on x64.

- Alex Suykov made the curl tool now assume that uploads using HTTP:// or
HTTPS:// are the only ones that show output and thus motivates a switched
off progress meter if the output is sent to the terminal. This makes FTP
uploads without '>', -o or -O show the progress meter.
Daniel (22 April 2005)
- Dave Dribin's MSVC makefile fix: set CURL_STATICLIB when it builds static
library variants.
- Andres Garcia fixed configure to set the proper define when building static
libcurl on windows.
- --retry-delay didn't work.
Daniel (18 April 2005)
- Olivier reported that even though he used CURLOPT_PORT, libcurl clearly
still used the default port. He was right. I fixed the problem and added the
test cases 521, 522 and 523 to verify the fix.
- Toshiyuki Maezawa reported that when doing a POST with a read callback,
libcurl didn't properly send an Expect: 100-continue header. It does now.
- I committed by mig change in the test suite's FTP server that moves out all
socket/TCP code to a separate C program named sockfilt. And added 4 new
test cases for FTP over IPv6.
Daniel (8 April 2005)
- Cory Nelson reported a problem with a HTTP server that responded with a 304
response containing an "illegal" Content-Length: header, which was not
properly ignored by libcurl. Now it is. Test case 249 verifies.

- Added ability to build and run with GnuTLS as an alternative to OpenSSL for
the secure layer. configure --with-gnutls enables with. Note that the
previous OpenSSL check still has preference and if it first detects OpenSSL,
it will not check for GnuTLS. You may need to explictly diable OpenSSL with
This work has been sponsored by The Written Word.
Daniel (5 April 2005)
- Christophe Legry fixed the post-upload check for FTP to not complain if the
upload was skipped due to a time-condition as set with
CURLOPT_TIMECONDITION. I added test case 247 and 248 to verify.
Version 7.13.2 (5 April 2005)
Daniel (4 April 2005)
- Marcelo Juchem fixed the MSVC makefile for libcurl
- Gisle Vanem fixed a crash in libcurl, that could happen if the easy handle
was killed before the threading resolver (windows only) still hadn't
- Hardeep Singh reported a problem doing HTTP POST with Digest. (It was
actually also affecting NTLM and Negotiate.) It turned out that if the
server responded with 100 Continue before the initial 401 response, libcurl
didn't take care of the response properly. Test case 245 and 246 added to
verify this.
Daniel (30 March 2005)
- Andres Garcia modified the configure script to check for libgdi32 before
libcrypto, to make the SSL check work fine on msys/mingw.
Daniel (29 March 2005)
- Tom Moers identified a flaw when you sent a POST with Digest authentication,
as in the first request when curl sends a POST with Content-Length: 0, it
still forcibly closed the connection before doing the next step in the auth
- Jesper Jensen found out that FTP-SSL didn't work since my FTP
rewrite. Fixing that was easy, but it also revealed a much worse problem:
the FTP server response reader function didn't properly deal with reading
responses in multiple tiny chunks properly! I modified the FTP server to
allow it to produce such split-up responses to make sure curl deals with
them as it should.
- Based on Augustus Saunders' comments and findings, the HTTP output auth
function was fixed to use the proper proxy authentication when multiple ones
are accepted. test 239 and test 243 were added to repeat the problems and
verify the fixes.
--proxy-anyauth was added to the curl tool
Daniel (16 March 2005)
- Tru64 and some IRIX boxes seem to not like test 237 as it is. Their
inet_addr() functions seems to use &255 on all numericals in a ipv4 dotted
address which makes a different failure... Now I've modified the ipv4
resolve code to use inet_pton() instead in an attempt to make these systems
better detect this as a bad IP address rather than creating a toally bogus
address that is then passed on and used.

- Dan Fandrich made the code properly use the uClibc's version of
inet_ntoa_r() when built with it.
- Added test 237 and 238: test EPSV and PASV response handling when they get
well- formated data back but using illegal values. In 237 PASV gets an IP
address that is way bad. In 238 EPSV gets a port that is way out of range.
Daniel (14 March 2005)
- Added a few missing features to the curl-config --features list
- Modified to now offer
1 - command line options for all info it previously only read from
file: --name, --email, --desc and --configure
2 - --nocvsup makes it not attempt to do cvs update
3 - --crosscompile informs it and makes it not attempt things it can't do
- Fixed numerous win32 compiler warnings.
- Removed the lib/security.h file since it shadowed the mingw/win32 header
with the same name which is needed for SSPI builds. The contents of the
former security.h is now i krb4.h
- configure --enable-sspi now enables SSPI in the build. It only works for
windows builds (including cross-compiles for windows).
