how it occurs (http://curl.haxx.se/mail/lib-2009-04/0289.html). The
conclusion was that if an error is detected and Curl_done() is called for
the connection, ftp_done() could at times return another error code that
then would take precedence and that new code confused existing logic that
works for the first error code (CURLE_SEND_ERROR) only.

OBJECTPOINT options. Now we've introduced a new function - my_setopt_str -
within the app for setting plain string options to avoid the risk of this
mistake happening.

Storsjo pointed out how setting CURLOPT_NOBODY to 0 could be downright
confusing as it set the method to either GET or HEAD. The example he showed
looked like:
curl_easy_setopt(curl, CURLOPT_PUT, 1);
curl_easy_setopt(curl, CURLOPT_NOBODY, 0);
The new way doesn't alter the method until the request is about to start. If
CURLOPT_NOBODY is then 1 the HTTP request will be HEAD. If CURLOPT_NOBODY is
0 and the request happens to have been set to HEAD, it will then instead be
set to GET. I believe this will be less surprising to users, and hopefully
not hit any existing users badly.

out to be leaking cacerts. Kamil Dudka helped me complete the fix. The issue
is found in Redhat's bug tracker:
https://bugzilla.redhat.com/show_bug.cgi?id=453612
There are still memory leaks present, but they seem to have other reasons.

non-configured libcurl. In this case curl_off_t data type was gated
to the off_t data type which depends on the _FILE_OFFSET_BITS. This
configuration is exactly the unwanted configuration for our curl_off_t
data type which must not depend on such setting. This breaks ABI for
libcurl libraries built with Sun compilers which were built without
having run the configure script with _FILE_OFFSET_BITS different than
64 and using the ILP32 data model.

curl_easy_duphandle did not necessarily duplicate the CURLOPT_COOKIEFILE
option. It only enabled the cookie engine in the destination handle if
data->cookies is not NULL (where data is the source handle). In case of a
newly initialized handle which just had the cookie support enabled by a
curl_easy_setopt(handle, CURL_COOKIEFILE, "")-call, handle->cookies was
still NULL because the setopt-call only appends the value to
data->change.cookielist, hence duplicating this handle would not have the
cookie engine switched on.
We also concluded that the slist-functionality would be suitable for being
put in its own module rather than simply hanging out in lib/sendf.c so I
created lib/slist.[ch] for them.

scripts to make it detect a bad checkout earlier. People with older
checkouts who don't do cvs update with the -d option won't get the new dirs
and then will get funny outputs that can be a bit hard to understand and
fix.

in the gnutls code where we were checking for negative values for errors,
when the man pages state that GNUTLS_E_SUCCESS is returned on success and
other values indicate error conditions.

curl didn't use sprintf() in a way that is documented to work in POSIX but
since we use our own printf() code (from libcurl) that shouldn't be a
problem. Nonetheless I modified the code to not rely on such particular
features and to not cause further raised eyebrowse with no good reason.

(http://curl.haxx.se/docs/adv_20090303.html also known as CVE-2009-0037) in
which previous libcurl versions (by design) can be tricked to access an
arbitrary local/different file instead of a remote one when
CURLOPT_FOLLOWLOCATION is enabled. This flaw is now fixed in this release
together this the addition of two new setopt options for controlling this
new behavior:
o CURLOPT_REDIR_PROTOCOLS controls what protocols libcurl is allowed to
follow to when CURLOPT_FOLLOWLOCATION is enabled. By default, this option
excludes the FILE and SCP protocols and thus you nee to explicitly allow
them in your app if you really want that behavior.
o CURLOPT_PROTOCOLS controls what protocol(s) libcurl is allowed to fetch
using the primary URL option. This is useful if you want to allow a user or
other outsiders control what URL to pass to libcurl and yet not allow all
protocols libcurl may have been built to support.

CURLOPT_LOCALPORT were used together (the local port bind failed), and
Markus Koetter provided the fix!

curl_global_init() function to properly maintain the performing functions
thread-safe. We've previously (28 April 2007) moved the init to a later time
just to avoid it to fail very early when libgcrypt dislikes the situation,
but that move was bad and the fix should rather be in libgcrypt or
elsewhere.

It happened because the code used the struct for server-based auth all the
time for both proxy and server auth which of course was wrong.

CURLINFO_CONTENT_LENGTH_DOWNLOAD and CURLINFO_CONTENT_LENGTH_UPLOAD return
-1 if the sizes aren't know. Previously these returned 0, make it impossible
to detect the difference between actually zero and unknown.

FTP with the multi interface: when a transfer fails, like when aborted by a
write callback, the control connection was wrongly closed and thus not
re-used properly.
This change is also an attempt to cleanup the code somewhat in this area, as
now the FTP code attempts to keep (better) track on pending responses
necessary to get read in ftp_done().

libcurl did a superfluous 1000ms wait when doing SFTP downloads!
We read data with libssh2 while doing the "DO" operation for SFTP and then
when we were about to start getting data for the actual file part, the
"TRANSFER" part, we waited for socket action (in 1000ms) before doing a
libssh2-read. But in this case libssh2 had already read and buffered the
data so we ended up always just waiting 1000ms before we get working on the
data!

plain FTP connections, and it will then allow MKD to fail once and retry the
CWD afterwards. This is especially useful if you're doing many simultanoes
connections against the same server and they all have this option enabled,
as then CWD may first fail but then another connection does MKD before this
connection and thus MKD fails but trying CWD works! The numbers can
(should?) now be set with the convenience enums now called
CURLFTP_CREATE_DIR and CURLFTP_CREATE_DIR_RETRY.
Tests has proven that if you're making an application that uploads a set of
files to an ftp server, you will get a noticable gain in speed if you're
using multiple connections and this option will be then be very useful.

the condition in the previous request was unmet. This is typically a time
condition set with CURLOPT_TIMECONDITION and was previously not possible to
reliably figure out. From bug report #2565128

version 1.1 instead of 1.0 like before. This change also introduces the new
proxy type for libcurl called 'CURLPROXY_HTTP_1_0' that then allows apps to
switch (back) to CONNECT 1.0 requests. The curl tool also got a --proxy1.0
option that works exactly like --proxy but sets CURLPROXY_HTTP_1_0.
I updated all test cases cases that use CONNECT and I tried to do some using
--proxy1.0 and some updated to do CONNECT 1.1 to get both versions run.

enabled, we can now take advantage of its brand new AF_UNSPEC support in
ares_gethostbyname(). This makes test case 241 finally run fine for me wtih

/etc/hosts file!

(http://curl.haxx.se/bug/view.cgi?id=2550061) mentioning that I failed to
properly make sure that the VC9 makefiles got included in the latest
release. I've now fixed the release script and verified it so next release
will hopefully include them properly!

CURLOPT_SOCKS5_GSSAPI_SERVICE and CURLOPT_SOCKS5_GSSAPI_NEC to allow libcurl
to do GSS-style authentication with SOCKS5 proxies. The curl tool got the
options called --socks5-gssapi-service and --socks5-gssapi-nec to enable
these.

disable "rfc4507bis session ticket support". rfc4507bis was later turned
into the proper RFC5077 it seems: http://tools.ietf.org/html/rfc5077
The enabled extension concerns the session management. I wonder how often
libcurl stops a connection and then resumes a TLS session. also, sending the
session data is some overhead. .I suggest that you just use your proposed
patch (which explicitly disables TICKET).
If someone writes an application with libcurl and openssl who wants to
enable the feature, one can do this in the SSL callback.
Sharad Gupta brought this to my attention. Peter Sylvester helped me decide
on the proper action.
