(http://curl.haxx.se/bug/view.cgi?id=1879375) which describes how libcurl
got lost in this scenario: proxy tunnel (or HTTPS over proxy), ask to do any
proxy authentication and the proxy replies with an auth (like NTLM) and then
closes the connection after that initial informational response.
libcurl would not properly re-initialize the connection to the proxy and
continue the auth negotiation like supposed. It does now however, as it will
now detect if one or more authentication methods were available and asked
for, and will thus retry the connection and continue from there.
- I made the progress callback get called properly during proxy CONNECT.

previously had a number of flaws, perhaps most notably when an application
fired up N transfers at once as then they wouldn't pipeline at all that
nicely as anyone would think... Test case 530 was also updated to take the
improved functionality into account.

problem that occurred when doing a large HTTP POST request with the
response-body read from a callback.
--keepalive-time to curl to set the keepalive probe interval. I also took
the opportunity to rename the recently added no-keep-alive option to
no-keepalive to keep a consistent naming and to avoid getting two dashes in
these option names. Eric also provided an update to the man page for the new
option.

libcurl to seek in a given input stream. This is particularly important when
doing upload resumes when there's already a huge part of the file present
remotely. Before, and still if this callback isn't used, libcurl will read
and through away the entire file up to the point to where the resuming
begins (which of course can be a slow opereration depending on file size,
I/O bandwidth and more). This new function will also be preferred to get
used instead of the CURLOPT_IOCTLFUNCTION for seeking back in a stream when
doing multi-stage HTTP auth with POST/PUT.
(http://curl.haxx.se/bug/view.cgi?id=1868255) with a patch. It identifies
and fixes a problem with parsing WWW-Authenticate: headers with additional
spaces in the line that the parser wasn't written to deal with.
(http://curl.haxx.se/bug/view.cgi?id=1863171) where he pointed out that
libcurl's date parser didn't accept a +1300 time zone which actually is used
fairly often (like New Zealand's Dailight Savings Time), so I modified the
parser to now accept up to and including -1400 to +1400.
code to instead introduce support for a new proxy type called
CURLPROXY_SOCKS5_HOSTNAME that is used to send the host name to the proxy
instead of IP address and there's thus no longer any need for a new
curl_easy_setopt() option.
The default SOCKS5 proxy is again back to sending the IP address to the
proxy. The new curl command line option for enabling sending host name to a
SOCKS5 proxy is now --socks5-hostname.

CURLOPT_SOCKS5_RESOLVE_LOCAL) is used we resolve the host name locally and
pass on the IP address only to the proxy.
made it an unsigned int. The type was only used in the curl_sockaddr struct
definition (only used by the curl_opensocket_callback). On all platforms I
could find information about, socklen_t is 32 unsigned bits large so I don't
think this will break the API or ABI. The main reason for this change is of
course for all the platforms that don't have a socklen_t definition in their
headers to build fine again. Providing our own configure magic and custom
definition of socklen_t on those systems proved to work but was a lot of
cruft, code and extra magic needed - when this very small change of type seems
harmless and still solves the missing socklen_t problem.
is an inofficial PROXY4 variant that sends the hostname to the proxy instead
of the resolved address (which is already supported by SOCKS5). --socks4a is
the curl command line option for it and CURLOPT_PROXYTYPE can now be set to
CURLPROXY_SOCKS4A as well.

(small) memory leak in the SSL session ID caching code. It happened when a
previous entry in the cache was re-used.
(http://curl.haxx.se/bug/view.cgi?id=1849764) with an included fix. He
identified a problem for re-used connections that previously had sent
Expect: 100-continue and in some situations the subsequent POST (that didn't
use Expect:) still had the internal flag set for its use. David's fix (that
makes the setting of the flag in every single request unconditionally) is
fine and is now used!
callback) over a proxy when NTLM is used as auth with the proxy. The bug
also concerned Digest and was limited to using callback only. Spacen worked
with us to provide a useful patch. I added the test case 547 and 548 to
verify two variations of POST over proxy with NTLM.
the appending of the "type=" thing on FTP URLs when they are passed to a
HTTP proxy. Some proxies just don't like that appending (which is done
unconditionally in 7.17.1), and some proxies treat binary/ascii transfers
better with the appending done!
the same state struct as the host auth, so both could never be used at the
same time! I fixed it (without being able to check) to use two separate
structs to allow authentication using Negotiate on host and proxy
simultanouesly.
callback was used, as it could wrongly pass on a bad size for the outgoing
HTTP header. The bad size would be a very large value as it was a wrapped
size_t content. This happened when the whole HTTP request failed to get sent
in one single send. http://curl.haxx.se/mail/lib-2007-11/0165.html
forwarded from the Gentoo bug tracker by Daniel Black and was originally
submitted by Robin Johnson, pointed out that libcurl would do bad memory
references when it failed and bailed out before the handler thing was
setup. My fix is not done like the provided patch does it, but instead I
make sure that there's never any chance for a NULL pointer in that struct
member.
out that SFTP requests didn't use persistent connections. Neither did SCP
ones. I gave the SSH code a good beating and now both SCP and SFTP should
use persistent connections fine. I also did a bunch for indent changes as
well as a bug fix for the "keyboard interactive" auth.
out a problem in curl.h when building C++ apps with MSVC. To fix it, the
inclusion of header files in curl.h is moved outside of the C++ extern "C"

accordingly.
https://bugzilla.novell.com/show_bug.cgi?id=332917 about a HTTP redirect to
FTP that caused memory havoc. His work together with my efforts created two
fixes:
#1 - FTP::file was moved to struct ftp_conn, because is has to be dealt with
at connection cleanup, at which time the struct HandleData could be
used by another connection.
Also, the unused char *urlpath member is removed from struct FTP.
#2 - provide a Curl_reset_reqproto() function that frees
data->reqdata.proto.* on connection setup if needed (that is if the
SessionHandle was used by a different connection).
This happened because the tftp code always uncondionally did a bind()
without caring if one already had been done and then it failed. I wrote a
test case (1009) to verify this, but it is a bit error-prone since it will
have to pick a fixed local port number and since the tests are run on so
many different hosts in different situations I add it in disabled state.
CURLOPT_OPENSOCKETDATA to set a callback that allows an application to replace
the socket() call used by libcurl. It basically allows the app to change
address, protocol or whatever of the socket. (I also did some whitespace
indent/cleanups in lib/url.c which kind of hides some of these changes, sorry
for mixing those in.)
CURLOPT_SSH_HOST_PUBLIC_KEY_MD5 and the curl tool --hostpubmd5. They both make
the SCP or SFTP connection verify the remote host's md5 checksum of the public
key before doing a connect, to reduce the risk of a man-in-the-middle attack.
function do wrong on all input bytes that are >= 0x80 (decimal 128) due to a
signed / unsigned mistake in the code. I fixed it and added test case 543 to
verify.
curl_easy_setopt() that alters how libcurl functions when following
redirects. It makes libcurl obey the RFC2616 when a 301 response is received
after a non-GET request is made. Default libcurl behaviour is to change
method to GET in the subsequent request (like it does for response code 302
- because that's what many/most browsers do), but with this CURLOPT_POST301
option enabled it will do what the spec says and do the next request using
the same method again. I.e keep POST after 301.
The curl tool got this option as --post301
Test case 1011 and 1012 were added to verify.
CURLOPT_NOBODY enabled but not CURLOPT_HEADER, libcurl wouldn't do TYPE
before it does SIZE which makes it less useful. I walked over the code and
made it do this properly, and added test case 542 to verify it.
o It looks for the NSS database first in the environment variable SSL_DIR,
then in /etc/pki/nssdb, then it initializes with no database if neither of
those exist.
o If the NSS PKCS#11 libnspsem.so driver is available then PEM files may be
loaded, including the ca-bundle. If it is not available then only
certificates already in the NSS database are used.
o Tries to detect whether a file or nickname is being passed in so the right
thing is done
o Added a bit of code to make the output more like the OpenSSL module,
including displaying the certificate information when connecting in
verbose mode
o Improved handling of certificate errors (expired, untrusted, etc)
The libnsspem.so PKCS#11 module is currently only available in Fedora
8/rawhide. Work will be done soon to upstream it. The NSS module will work
with or without it, all that changes is the source of the certificates and
keys.
key was specified and there was no HOME environment variable, and then it
didn't continue to try the other auth methods. Now it will instead try to
get the files id_dsa.pub and id_dsa from the current directory if none of
the two conditions were met.
- Bug report #1792649 (http://curl.haxx.se/bug/view.cgi?id=1792649) pointed
out a problem with doing an empty upload over FTP on a re-used connection.
I added test case 541 to reproduce it and to verify the fix.
- I noticed while writing test 541 that the FTP code wrongly did a CWD on the
second transfer as it didn't store and remember the "" path from the
previous transfer so it would instead CWD to the entry path as stored. This
worked, but did a superfluous command. Thus, test case 541 now also verifies
this fix.
and allow reuse by multiple protocols. Several unused error codes were
removed. In all cases, macros were added to preserve source (and binary)
compatibility with the old names. These macros are subject to removal at
a future date, but probably not before 2009. An application can be
tested to see if it is using any obsolete code by compiling it with the
CURL_NO_OLDIES macro defined.
Documented some newer error codes in libcurl-error(3)
out that libcurl didn't deal with large responses from server commands, when
the single response was consisting of multiple lines but of a total size of
16KB or more. Dan Fandrich improved the ftp test script and provided test
case 1006 to repeat the problem, and I fixed the code to make sure this new
test case runs fine.
out that doing first a file:// upload and then an FTP upload crashed libcurl
or at best caused furious valgrind complaints. Fixed now by making sure we
free and clear the file-specific struct properly when done with it.
out that libcurl didn't deal with very long (>16K) FTP server response lines
properly. Starting now, libcurl will chop them off (thus the client app will
not get the full line) but survive and deal with them fine otherwise. Test
case 1003 was added to verify this.
(http://curl.haxx.se/bug/view.cgi?id=1776232) about libcurl calling
Curl_client_write(), passing on a const string that the caller may not
modify and yet it does (on some platforms).
(http://curl.haxx.se/bug/view.cgi?id=1776235) about ftp requests with NOBODY
on a directory would do a "SIZE (null)" request. This is now fixed and test
case 1000 was added to verify.
the configure script checks for openldap and friends and we link with those
libs just like we link all other third party libraries, and we no longer
dlopen() those libraries. Our private header file lib/ldap.h was renamed to
lib/curl_ldap.h due to this. I set a tag in CVS (curl-7_17_0-preldapfix)
just before this commit, just in case.
(http://curl.haxx.se/bug/view.cgi?id=1766320) pointing out that the libcurl
code accessed two curl_easy_setopt() options (CURLOPT_DNS_CACHE_TIMEOUT and
CURLOPT_DNS_USE_GLOBAL_CACHE) as ints even though they're documented to be
passed in as longs, and that makes a difference on 64 bit architectures.

to the data, forcing the user to keep the data around until libcurl is done
with it. That is now history and libcurl will instead clone the given
strings and keep private copies.
NTLM, and he provided test code and a test server and we worked out a bug
fix. We failed to count sent body data at times, which then caused internal
confusions when libcurl tried to send the rest of the data in order to
maintain the same connection alive.
(and then I did some minor reformatting of code in lib/http.c)
(http://curl.haxx.se/bug/view.cgi?id=1757328) and submitted a patch. It turns
out we broke login to FTP servers that don't require (nor understand) PASS

case where libcurl did a connect attempt to a non-listening port and didn't

We should deprecate the support for this set to 1 anyway soon, since the
feature is pointless and most likely never really used by anyone.
The tiny patch below fixes a bug (that I introduced :) which happens
when negotiating authentication with a proxy (probably with web
servers as well) that uses chunked transfer encoding for the 407 error
pages. In this case the ''ignorebody'' flag was ignored (no pun
intended).

RFC2616 section 4.4 point #5 says we should behave.
http://curl.haxx.se/mail/lib-2007-06/0238.html, libcurl didn't properly do
no-body requests on FTP files on re-used connections properly, or at least
it didn't provide the info back in the header callback properly in the
subsequent requests.
(http://curl.haxx.se/bug/view.cgi?id=1740263). Adam discovered that when
getting a large amount of URLs with curl, they were fetched slower and
slower... which turned out to be because the --libcurl data collecting which
wrongly always was enabled, but no longer is...
(http://curl.haxx.se/bug/view.cgi?id=1739100) that mentioned that libcurl
could not actually list the contents of the root directory of a given FTP
server if the login directory isn't root. I fixed the problem and added three
test cases (one is disabled for now since I identified KNOWN_BUGS #44, we
cannot use --ftp-method nocwd and list ftp directories).
(http://curl.haxx.se/bug/view.cgi?id=1733119) and we collaborated on the fix.
The problem is that for 64bit HPUX builds, several socket-related functions
would still assume int (32 bit) arguments and not socklen_t (64 bit) ones.

fixed two minor SOCKS problems to make the test cases run fine.
to find that it crashed miserably, and this was due to some select()isms left
in the code. This was due to API restrictions in c-ares 1.3.x, but with the
upcoming c-ares 1.4.0 this is no longer the case so now libcurl runs much
better with c-ares and the multi interface with > 1024 file descriptors in

- Shmulik Regev added CURLOPT_HTTP_CONTENT_DECODING and
CURLOPT_HTTP_TRANSFER_DECODING that if set to zero will disable libcurl's
internal decoding of content or transfer encoded content. This may be
preferable in cases where you use libcurl for proxy purposes or similar. The

timeouts with millisecond resolution instead. The only restriction to that
is the alarm() (sometimes) used to abort name resolves as that uses full

Internally we now count and keep the timeouts in milliseconds but it also
means we multiply set timeouts with 1000. The effect of this is that no
timeout can be set to more than 2^31 milliseconds (on 32 bit systems), which
equals 24.86 days. We probably couldn't before either since the code did
