the define CURL_MAX_HTTP_HEADER which is even exposed in the public header

header callback with the entire header, but that also risk getting it into
trouble if a server by mistake or willingly sends a header that is more or
less without an end. The limit is set to 100K.

Apparently at least one CA allowed a subjectAltName or CN that contain a
zero byte, and thus clients that assumed they would never have zero bytes
were exploited to OK a certificate that didn't actually match the site. Like
if the name in the cert was "example.com\0theatualsite.com", libcurl would
happily verify that cert for example.com.
libcurl now better use the length of the extracted name, not assuming it is

CURLOPT_PREQUOTE) now accept a preceeding asterisk before the command to
send when using FTP, as a sign that libcurl shall simply ignore the response

chain of commands, nor will they cause the connection to get disconnected.

out that the cookie parser would leak memory when it parses cookies that are

There's still a flaw in the FTP code for this.
(http://curl.haxx.se/bug/view.cgi?id=2786255) with a patch, identifying how
libcurl did not deal with SSL session ids properly if the server rejected a
re-use of one. Starting now, it will forget the rejected one and remember
the new. This change was for OpenSSL only, it is likely that other SSL lib
code needs similar fixes.
I've now made TFTP "connections" not being kept for re-use within libcurl.
TFTP is UDP-based so the benefit was really low (if even existing) to begin
with so instead of tracking down to fix this problem we instead removed the
re-use. I also enabled test case 1099 that I wrote a few days ago to verify
that this change fixes the reported problem.
Chen pointed out how curl couldn't upload with resume when reading from a
pipe.
This ended up with the introduction of a new return code for the
CURLOPT_SEEKFUNCTION callback that basically says that the seek failed but
that libcurl may try to resolve the situation anyway. In our case this means
libcurl will attempt to instead read that much data from the stream instead
of seeking and that way curl can now upload with resume when data is read
from a stream!
Previous workaround proved useful, but triggered the following warning:
warning #556: a value of type "volatile Curl_addrinfo *" cannot be assigned to an entity of type "Curl_addrinfo *"

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.
proxy. libcurl would then wrongly close the connection after each
request. In his case it had the weird side-effect that it killed NTLM auth
for the proxy causing an inifinite loop!
I added test case 1098 to verify this fix. The test case does however not
properly verify that the transfers are done persistently - as I couldn't
think of a clever way to achieve it right now - but you need to read the
stderr output after a test run to see that it truly did the right thing.
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.
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.

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.

elsewhere.
CURLINFO_CONTENT_LENGTH_DOWNLOAD and CURLINFO_CONTENT_LENGTH_UPLOAD return

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.

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

libcurl stops a connection and then resumes a TLS session. also, sending the

When using the multi interface over HTTP and the server returns a Location
header, the running easy handle will get stuck in the CURLM_STATE_PERFORM
state, leaving the external event loop stuck waiting for data from the
ingoing socket (when using the curl_multi_socket_action stuff). While this
bug was pretty hard to find, it seems to require only a one-line fix. The
break statement on line 1374 in multi.c caused the function to skip the call
to multistate().
How to reproduce this bug? Well, that's another question. evhiperfifo.c in
the examples directory chokes on this bug only _sometimes_, probably
depending on how fast the URLs are added. One way of testing the bug out is
writing to hiper.fifo from more than one source at the same time.
curl_easy_reset() by creating Curl_init_userdefined(). This had the side effect
of fixing curl_easy_reset() so it now also resets CURLOPT_FTP_FILEMETHOD and

I have to jump through a few hoops now with the NSS library initialization
since another part of an application may have already initialized NSS by the
time Curl gets invoked. This patch is more careful to only shutdown the NSS
library if Curl did the initialization.
It also adds in a bit of code to set the default ciphers if the app that
call NSS_Init* did not call NSS_SetDomesticPolicy() or set specific
ciphers. One might argue that this lets other application developers get
lazy and/or they aren't using the NSS API correctly, and you'd be right.
But still, this will avoid terribly difficult-to-trace crashes and is
generally helpful.

operation didn't complete properly if the EAGAIN equivalent was returned but
libcurl would simply continue with a half-completed close operation

blocking function - doing it entirely non-blocking should be considered for
a better fix.

In other words: the change I did on September 30th 2008 and that has been

that libcurl knows what socket conditions to wait for before trying the
function call again. Previously (and still when using libssh2 0.18 or
earlier), libcurl will busy-loop in this situation when the easy interface
is used!
when uploading files to a single FTP server using multiple easy handle
handles with the multi interface. Occasionally a handle would stall in
mysterious ways.
The problem turned out to be a side-effect of the ConnectionExists()
function's eagerness to re-use a handle for HTTP pipelining so it would
select it even if already being in use, due to an inadequate check for its
chances of being used for pipelnining.
codes for all calls to malloc and strdup that were missing. I also changed
a few malloc(13) to use arrays on the stack and a few malloc(PATH_MAX) to
instead use aprintf() to lower memory use.
I also fixed a memory leak in Curl_nss_connect() when CURLOPT_ISSUERCERT is
in use.
(http://curl.haxx.se/bug/view.cgi?id=2255627) which pointed out that a
program using libcurl's multi interface to download a HTTPS page with a
libcurl built powered by OpenSSL, would easily get silly and instead hand
over SSL details as data instead of the actual HTTP headers and body. This
happened because libcurl would consider the connection handshake done too
early. This problem was introduced at September 22nd 2008 with my fix of the
bug #2107377
The correct fix is now instead done within the GnuTLS-handling code, as both
the OpenSSL and the NSS code already deal with this situation in similar
fashion. I added test case 560 in an attempt to verify this fix, but
unfortunately it didn't trigger it even before this fix!
problem with my CURLINFO_PRIMARY_IP fix from October 7th that caused a NULL
pointer read. I also took the opportunity to clean up this logic (storing of
the connection's IP address) somewhat as we had it stored in two different
places and ways previously and they are now unified.
