overrun" (http://curl.haxx.se/bug/view.cgi?id=2026240) identifying two
problems, and providing the fix for them:
- CURL_READFUNC_PAUSE did in fact not pause the _sending_ of data that it is
designed for but paused _receiving_ of data!
- libcurl didn't internally set the read counter to zero when this return
code was detected, which would potentially lead to junk getting sent to
the server.
non-zero with the fixed value of 1. We should strive at making options
support '1' for enabling them mentioned explicitly, as that then will allow
us for to extend them in the future without breaking older programs.
finds out its return type and the types of its arguments. Added definitions
for non-configure systems config files, and introduced macro sreadfrom which
will be used on udp sockets as a recvfrom() wrapper.

this will solve the "Permission denied" problem that Nagarajan Sreenivasan
reported when setting some modes, but regardless, it saves a protocol
round trip in the chmod case.
is set in fdset.events" (http://curl.haxx.se/bug/view.cgi?id=2015126) which
exactly pinpointed the problem only triggered on Windows Vista, provided
reference to docs and also a fix. There is much work behind Peter Lamberg's
excellent bug report. Thank You!
fix for it. It occured when you did a FTP transfer using
CURLFTPMETHOD_SINGLECWD and then did another one on the same easy handle but
switched to CURLFTPMETHOD_NOCWD. Due to the "dir depth" variable not being
cleared properly. Scott's test case is now known as test 539 and it
verifies the fix.
CURLINFO_APPCONNECT_TIME. This is set with the "application layer"
handshake/connection is completed (typically SSL, TLS or SSH). By using this
you can figure out the application layer's own connect time. You can extract
the time stamp using curl's -w option and the new variable named
'time_appconnect'. This feature was sponsored by Lenny Rachitsky at NeuStar.
some systems" (http://curl.haxx.se/bug/view.cgi?id=1999181). The problem was
that the configure script did not use the _POSIX_MONOTONIC_CLOCK feature test
macro when checking monotonic clock availability. This is now fixed and the
monotonic clock will not be used unless the feature test macro is defined
with a value greater than zero indicating always supported.
(http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=487567) pointing out that
libcurl used Content-Range: instead of Range when doing a range request with
--head (CURLOPT_NOBODY). This is now fixed and test case 1032 was added to
verify.
enough at detecting compilation errors or at least it has been properly
configured to do so. Configuration heavily depends on this capability, so
if this compiler sanity check fails the configuration process will now fail.
handshake with a SSLv2 server, and it turned out to be because it didn't
recognize the cipher named "rc4-md5". In our list that cipher was named
plainly "rc4". I've now added rc4-md5 to work as an alias as Phil reported
that it made things work for him again.
crashed libcurl. This is now addressed by making sure we use "plain send"
internally when doing the socks handshake instead of the Curl_write()
function which is designed to use the "target" protocol. That's then SCP or
SFTP in this case. I also took the opportunity and cleaned up some ssh-
related #ifdefs in the code for readability.
libcurl to not tell the app properly when a socket was closed (when the name
resolve done by c-ares is done) and then immediately re-created and put to
use again (for the actual connection). Since the closure will make the
"watch status" get lost in several event-based systems libcurl will need to
tell the app about this close/re-create case.
multi interface with pipelining enabled as it would wrongly check for,
detect and close "dead connections" even though that connection was already
in use!
libraries are supported. Starting now, each underlying SSL library support
code does a set of defines for the 16 functions the generic layer (sslgen.c)
uses (all these new function defines use the prefix "curlssl_"). This
greatly simplified the generic layer in readability by involving much less
#ifdefs and other preprocessor stuff and should make it easier for people to
make libcurl work with new SSL libraries.
Hopefully I can later on document these 16 functions somewhat as well.
I also made most of the internal SSL-dependent functions (using Curl_ssl_
prefix) #defined to nothing when no SSL support is requested - previously
they would unnecessarily call mostly empty functions.
All boolean options (such as -O, -I, -v etc), both short and long versions,
now always switch on/enable the option named. Using the same option multiple
times thus make no difference. To switch off one of those options, you need
to use the long version of the option and type --no-OPTION. Like to disable
verbose mode you use --no-verbose!
- Added --remote-name-all to curl, which if used changes the default for all
given URLs to be dealt with as if -O is used. So if you want to disable that
for a specific URL after --remote-name-all has been used, you muse use -o -
or --no-remote-name.
curl_easy_getinfo. It returns a pointer to a string with the most recently
used IP address. Modified test case 500 to also verify this feature. The
implementing of this feature was sponsored by Lenny Rachitsky at NeuStar.
- Updated main.c to return CURLE_OK if PARAM_HELP_REQUESTED was returned
from getparameter instead of CURLE_FAILED_INIT. No point in returning
an error if --help or --version were requested.
the curl_multi_socket() API with HTTP pipelining enabled and could lead to
the pipeline basically stalling for a very long period of time until it took
off again.
provided excellent repeat recipes. I fixed the cases I managed to reproduce
but Jeff still got some (SCP) problems even after these fixes:
http://curl.haxx.se/mail/lib-2008-05/0342.html
how the HTTP redirect following code didn't properly follow to a new URL if
the new url was but a query string such as "Location: ?moo=foo". Test case
1031 was added to verify this fix.
interface problems:
o with pipelining disabled, the state should never be set to WAITDO but
rather go straight to DO
o we had multiple states for which the internal function returned no socket
at all to wait for, with the effect that libcurl calls the socket callback
(when curl_multi_socket() is used) with REMOVE prematurely (as it would be
added again within very shortly)
o when in DO and DOING states, the HTTP and HTTPS protocol handler functions
didn't return that the socket should be waited for writing, but instead it
was treated as if no socket was needing monitoring so again REMOVE was
called prematurely.
and receive data over a connection previously setup with curl_easy_perform()
and its CURLOPT_CONNECT_ONLY option. The sendrecv.c example was added to
show how they can be used.
when using CURL_AUTH_ANY" (http://curl.haxx.se/bug/view.cgi?id=1945240).
The problem was that when libcurl rewound a stream meant for upload when it
would prepare for a second request, it could accidentally continue the
sending of the rewound data on the first request instead of on the second.
Ben also provided test case 1030 that verifies this fix.
since libcurl used getprotobyname() and that isn't thread-safe. We now
switched to use IPPROTO_TCP unconditionally, but perhaps the proper fix is
to detect the thread-safe version of the function and use that.

redirections and thus cannot use CURLOPT_FOLLOWLOCATION easily, we now
introduce the new CURLINFO_REDIRECT_URL option that lets applications
extract the URL libcurl would've redirected to if it had been told to. This
then enables the application to continue to that URL as it thinks is
suitable, without having to re-implement the magic of creating the new URL
from the Location: header etc. Test 1029 verifies it.
Define HAVE_GSSMIT if <gssapi/{gssapi.h,gssapi_generic.h,gssapi_krb5.h}> are
available, otherwise define HAVE_GSSHEIMDAL if <gssapi.h> is available.
Only define GSS_C_NT_HOSTBASED_SERVICE to gss_nt_service_name if
GSS_C_NT_HOSTBASED_SERVICE isn't declared by the gssapi headers. This should
avoid breakage in case we wrongly recognize Heimdal as MIT again.
message when libcurl doesn't get a 220 back immediately on connect, I now
changed it to be more specific on what the problem is. Also worth noticing:
while the bug report contains an example where the response is:
421 There are too many connected users, please try again later
we cannot assume that the error message will always be this readable nor
that it fits within a particular boundary etc.
GET simply because previously when you set CURLOPT_NOBODY to TRUE first and
then FALSE you'd end up in a broken state where a HTTP request would do a
HEAD by still act a lot like for a GET and hang waiting for the content etc.
application to provide data for a multipart with the read callback. Note
that the size needs to be provided with CURLFORM_CONTENTSLENGTH when the
stream option is used. This feature is verified by the new test case
554. This feature was sponsored by Xponaut.
support when curl didn't even have regular LDAP support. It looks like
this could happen when the --enable-ldaps configure switch is given but
configure couldn't find the LDAP headers or libraries.
default instead of a ca bundle. The configure script will also look for a
ca path if no ca bundle is found and no option given.
- Fixed detection of previously installed curl-ca-bundle.crt
CURLOPT_FTP_CREATE_MISSING_DIRS to create a directory, and then re-used the
handle and uploaded another file to another directory that needed to be
created, the second upload would fail. Another case of a state variable that
wasn't properly reset between requests.
- I rewrote the 100-continue code to use a single state variable instead of
the previous two ones. I think it made the logic somewhat clearer.

does nothing with them, just to make sure libcurl users always use three
arguments to this function. Due to its use of ... for the third argument, it
is otherwise hard to detect abuse.
easy handle if curl_easy_reset() was used between them. I fixed it and Brian
verified that it cured his problem.
- Brian Ulm reported that if you first tried to download a non-existing SFTP
file and then fetched an existing one and re-used the handle, libcurl would
still report the second one as non-existing as well! I fixed it abd Brian
verified that it cured his problem.
select/poll calls will only be retried upon EINTR failures as
it previously was in lib/select.c revision 1.29
In this way Curl_socket_ready() and Curl_poll() will again fail
on any select/poll errors different than EINTR.
better control at the exact state of the connection's SSL status so that we
know exactly when it has completed the SSL negotiation or not so that there
won't be accidental re-uses of connections that are wrongly believed to be
in SSL-completed-negotiate state.

following. The patch that introduced this feature was done for 7.11.0, but
this code and functionality has been broken since about 7.15.4 (March 2006)
with the introduction of non-blocking OpenSSL "connects".
It was a hack to begin with and since it doesn't work and hasn't worked
correctly for a long time and nobody has even noticed, I consider it a very
suitable subject for plain removal. And so it was done.
get a fresh one downloaded and created with 'make ca-bundle' or you can get
one from here => http://curl.haxx.se/docs/caextract.html if you want a fresh
new one extracted from Mozilla's recent list of ca certs.
The configure option --with-ca-bundle now lets you specify what file to use
as default ca bundle for your build. If not specified, the configure script
will check a few known standard places for a global ca cert to use.
connection by force when it was called before the entire request is
completed, simply because we can't know if the connection really can be
re-used safely at that point.
verification is requested. Previously it would even return failure if gnutls
failed to get the server cert even though no verification was asked for.
- Fix my Curl_timeleft() leftover mistake in the gnutls code
out and provides test program that demonstrates that libcurl might not set
error description message for error CURLE_COULDNT_RESOLVE_HOST for Windows
threaded name resolver builds. Fixed now.
(http://curl.haxx.se/bug/view.cgi?id=1889856): When using the gnutls ssl
layer, cleaning-up and reinitializing curl ends up with https requests
failing with "ASN1 parser: Element was not found" errors. Obviously a
regression added in 7.16.3.
all curl's tests generated configuration and key files are fine, a real
connection is established to the test harness sftp server authenticating
and running a simple sftp remote pwd command.
The verification is done using OpenSSH's or SunSSH's sftp client tool with
a configuration file with the same options as the test harness socks server
with the exception that dynamic forwarding is not used for sftp.
