duphandle+curl_mutli" (http://curl.haxx.se/bug/view.cgi?id=2416182) showed
that curl_easy_duphandle() wrongly also copied the pointer to the connection
cache, which was plain wrong and caused a segfault if the handle would be
used in a different multi handle than the handle it was duplicated from.
there are servers "out there" that relies on the client doing this broken
Digest authentication. Apache even comes with an option to work with such
broken clients.
The difference is only for URLs that contain a query-part (a '?'-letter and
text to the right of it).
libcurl now supports this quirk, and you enable it by setting the
CURLAUTH_DIGEST_IE bit in the bitmask you pass to the CURLOPT_HTTPAUTH or
CURLOPT_PROXYAUTH options. They are thus individually controlled to server
and proxy.
particular state for the control connection like it did before for implicit
FTPS (libcurl assumed such control connections to be encrypted while some
FTPS servers such as FileZilla assumes such connections to be clear
mode). Use the CURLOPT_USE_SSL option to set your desired level.
researching it, it turned out he got a 550 response back from a SIZE command
and then I fell over the text in RFC3659 that says:
The presence of the 550 error response to a SIZE command MUST NOT be taken
by the client as an indication that the file cannot be transferred in the
current MODE and TYPE.
In other words: the change I did on September 30th 2008 and that has been
included in the last two releases were a regression and a bad idea. We MUST
NOT take a 550 response from SIZE as a hint that the file doesn't exist.
(http://curl.haxx.se/bug/view.cgi?id=2221237) that identified an infinite
loop during GSS authentication given some specific conditions. With his
patience and great feedback I managed to narrow down the problem and
eventually fix it although I can't test any of this myself!
(http://curl.haxx.se/bug/view.cgi?id=2351645) that identified a problem with
the multi interface that occured if you removed an easy handle while in
progress and the handle was used in a HTTP pipeline.
function when built to support SCP and SFTP that helps the library to know
in which direction a particular libssh2 operation would return EAGAIN so
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.
(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 MSVC 6 makefile that caused a build failure. It was noted that
the curl_addrinfo.obj reference was missing. I took the opportunity to sort
the list in which this was missing.
make CURLOPT_PROXYUSERPWD sort of deprecated. The primary motive for adding
these new options is that they have no problems with the colon separator
that the CURLOPT_PROXYUSERPWD option does.
(http://curl.haxx.se/bug/view.cgi?id=2154627) which pointed out that libcurl
uses strcasecmp() in multiple places where it causes failures when the
Turkish locale is used. This is because 'i' and 'I' isn't the same letter so
strcasecmp() on those letters are different in Turkish than in English (or
just about all other languages). I thus introduced a totally new internal
function in libcurl (called Curl_ascii_equal) for doing case insentive
comparisons for english-(ascii?) style strings that thus will make "file"
and "FILE" match even if the Turkish locale is selected.
systems supporting getifaddrs(). Also fixed a problem where an IPv6
address could be chosen instead of an IPv4 one for --interface when it
involved a name lookup.
fixed a CURLINFO_REDIRECT_URL memory leak and an additional wrong-doing:
Any subsequent transfer with a redirect leaks memory, eventually crashing
the process potentially.
Any subsequent transfer WITHOUT a redirect causes the most recent redirect
that DID occur on some previous transfer to still be reported.
eventually identified a flaw in how the multi_socket interface in some cases
missed to call the timeout callback when easy interfaces are removed and
added within the same millisecond.
curl_easy_setopt: CURLOPT_USERNAME and CURLOPT_PASSWORD that sort of
deprecates the good old CURLOPT_USERPWD since they allow applications to set
the user name and password independently and perhaps more importantly allow
both to contain colon(s) which CURLOPT_USERPWD doesn't fully support.
the app re-used the handle to do a connection to host B and then again
re-used the handle to host A, it would not update the info with host A's IP
address (due to the connection being re-used) but it would instead report
the info from host B.
gets a 550 response back for the cases where a download (or NOBODY) is
wanted. It still allows a 550 as response if the SIZE is used as part of an
upload process (like if resuming an upload is requested and the file isn't
there before the upload). I also modified the FTP test server and a few test
cases accordingly to match this modified behavior.
date parser function. This makes our function less dependent on system-
provided functions and instead we do all the magic ourselves. We also no
longer depend on the TZ environment variable.
Markus Moeller reported: http://curl.haxx.se/mail/archive-2008-09/0016.html
- recv() errors other than those equal to EAGAIN now cause proper
CURLE_RECV_ERROR to get returned. This made test case 160 fail so I've now
disabled it until we can figure out another way to exercise that logic.
proxy" (http://curl.haxx.se/bug/view.cgi?id=2107377) that showed how a multi
interface using program didn't work when built with GnuTLS and a CONNECT
request was done over a proxy (basically test 502 over a proxy to a HTTPS
site). It turned out the ssl connect function would get called twice which
caused the second call to fail.
