Binary package hint: curl
curl 7.19.7 has been released
Version 7.19.7 (4 November 2009)
Daniel Stenberg (2 Nov 2009)
- As reported independent by both Stan van de Burgt and Didier Brisebourg,
CURLINFO_SIZE_DOWNLOAD (the -w variable size_download) didn't work when
getting data from ldap!
Daniel Stenberg (31 Oct 2009)
- Gabriel Kuri reported a problem with CURLINFO_CONTENT_LENGTH_DOWNLOAD if the
download was 0 bytes, as libcurl would then return the size as unknown (-1)
and not 0. I wrote a fix and test case 566 to verify it.
Daniel Stenberg (30 Oct 2009)
- Liza Alenchery mentioned a problem with re-used SCP connection when a bad
auth is used, as it caused a crash. I failed to repeat the issue, but still
made a change that now forces the TCP connection used for a freed SCP
session to get closed and not be re-used.
- "Tom" posted a bug report that mentioned how libcurl did wrong when doing a
POST using a read callback, with Digest authentication and
"Transfer-Encoding: chunked" enforced. I would then cause the first request
to be wrongly sent and then basically hang until the server closed the
connection. I fixed the problem and added test case 565 to verify it.
Daniel Stenberg (25 Oct 2009)
- Dima Barsky made the curl cookie parser accept cookies even with blank or
unparsable expiry dates and then treat them as session cookies - previously
libcurl would reject cookies with a date format it couldn't parse. Research
shows that the major browser treat such cookies as session cookies. I
modified test 8 and 31 to verify this.
Daniel Stenberg (21 Oct 2009)
- Attempt to use pkg-config for finding out libssh2 installation details
during configure.
- A patch in bug report #2883177 (http://curl.haxx.se/bug/view.cgi?id=2883177)
by Johan van Selst introduced the --crlfile option to curl, which makes curl
tell libcurl about a file with CRL (certificate revocation list) data to
read.
Daniel Stenberg (18 Oct 2009)
- Ray Dassen provided a patch in Debian's bug tracker (bug number #551461)
that now makes curl_getdate(3) actually handles RFC 822 formatted dates that
use the "single letter military timezones".
http://www.rfc-ref.org/RFC-TEXTS/822/chapter5.html has the details.
- Fixed memory leak in the SCP/SFTP code as it never freed the knownhosts
data!
- John Dennis filed bug report #2873666
(http://curl.haxx.se/bug/view.cgi?id=2873666) which identified a problem
which made libcurl loop infinitely when given incorrect credentials when
using HTTP GSS negotiate authentication. He also provided a small and simple
patch for it.
- Kevin Baughman found a double close() problem with libcurl-NSS, as when
libcurl called NSS to close the SSL "session" it also closed the actual
socket.
Yang Tse (17 Oct 2009)
- Bug report #2866724 indicated
(http://curl.haxx.se/bug/view.cgi?id=2866724) that curl on Windows failed
when writing files whose file names originally contained characters which
are not valid for file names on Windows. Dan Fandrich provided an initial
patch and another revised one to fix this issue.
Daniel Stenberg (1 Oct 2009)
- Tom Mueller correctly reported in bug report #2870221
(http://curl.haxx.se/bug/view.cgi?id=2870221) that libcurl returned an
incorrect return code from the internal trynextip() function which caused
him grief. This is a regression that was introduced in 7.19.1 and I find it
strange it hasn't hit us harder, but I won't persue into figuring out
exactly why.
- Constantine Sapuntzakis: The current implementation will always set
SO_SNDBUF to CURL_WRITE_SIZE even if the SO_SNDBUF starts out larger. The
patch doesn't do a setsockopt if SO_SNDBUF is already greater than
CURL_WRITE_SIZE. This should help folks who have set up their computer with
large send buffers.
Daniel Stenberg (27 Sep 2009)
- I introduced a maximum limit for received HTTP headers. It is controlled by
the define CURL_MAX_HTTP_HEADER which is even exposed in the public header
file to allow for users to fairly easy rebuild libcurl with a modified
limit. The rationale for a fixed limit is that libcurl is realloc()ing a
buffer to be able to put a full header into it, so that it can call the
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.
Daniel Stenberg (26 Sep 2009)
- John P. McCaskey posted a bug report that showed how libcurl did wrong when
saving received cookies with no given path, if the path in the request had a
query part. That is means a question mark (?) and characters on the right
side of that. I wrote test case 1105 and fixed this problem.
Kamil Dudka (26 Sep 2009)
- Implemented a protocol independent way to specify blocking direction, used by
transfer.c for blocking. It is currently used only by SCP and SFTP protocols.
This enhancement resolves an issue with 100% CPU usage during SFTP upload,
reported by Vourhey.
Daniel Stenberg (25 Sep 2009)
- Chris Mumford filed bug report #2861587
(http://curl.haxx.se/bug/view.cgi?id=2861587) identifying that libcurl used
the OpenSSL function X509_load_crl_file() wrongly and failed if it would
load a CRL file with more than one certificate within. This is now fixed.
Daniel Stenberg (16 Sep 2009)
- Sven Anders reported that we introduced a cert verfication flaw for OpenSSL-
powered libcurl in 7.19.6. If there was a X509v3 Subject Alternative Name
field in the certficate it had to match and so even if non-DNS and non-IP
entry was present it caused the verification to fail.
Daniel Fandrich (15 Sep 2009)
- Moved the libssh2 checks after the SSL library checks. This helps when
statically linking since libssh2 needs the SSL library link flags to be
set up already to satisfy its dependencies. This wouldn't be necessary if
the libssh2 configure check was changed to use pkg-config since the
--static flag would add the dependencies automatically.
Yang Tse (14 Sep 2009)
- Revert Joshua Kwan's patch committed 11 Sep 2009.
Some systems poll function sets POLLHUP in revents without setting
POLLIN, and sets POLLERR without setting POLLIN and POLLOUT. In some
libcurl code execution paths this could trigger busy wait loops with
high CPU usage until a timeout condition aborted the loop.
The reverted patch addressed the above issue for a very specific case,
when awaiting c-ares to resolve. A libcurl-wide fix for Curl_poll now
superceeds this one.
Guenter Knauf (11 Sep 2009)
- Joshua Kwan provided a patch to pass POLLERR / POLLHUP back to c-ares.
This fixes a loop problem with high CPU usage.
Daniel Stenberg (10 Sep 2009)
- Claes Jakobsson fixed a problem with cookie expiry dates at exctly the epoch
start second "Thu Jan 1 00:00:00 GMT 1970" as the date parser then returns 0
which internally then is treated as a session cookie. That particular date
is now made to get the value of 1.
Daniel Stenberg (2 Sep 2009)
- Daniel Johnson found a flaw in the code converting sftp-errors to libcurl
errors.
Daniel Stenberg (1 Sep 2009)
- Peter Sylvester made a debug feature for Curl_resolv() that now will force
libcurl to resolve 'localhost' whatever name you use in the URL *if* you set
the --interface option to (exactly) "LocalHost". This will enable us to
write tests for custom hosts names but still use a local host server.
- configure now tries to use pkg-config for a number of sub-dependencies even
when cross-compiling. The key to success is then you properly setup
PKG_CONFIG_PATH before invoking configure.
I also improved how NSS is detected by trying nss-config if pkg-config isn't
present, and as a last resort just use the lib name and force the user to
setup the LIBS/LDFLAGS/CFLAGS etc properly. The previous last resort would
add a range of various libs that would almost never be quite correct.
Daniel Stenberg (31 Aug 2009)
- When using the multi interface with FTP and you asked for NOBODY, you did no
QUOTE commands and the request used the same path as the connection had
already changed to, it would decide that no commands would be necessary for
the "DO" action and that was not handled properly but libcurl would instead
hang.
Kamil Dudka (28 Aug 2009)
- Improved error message for not matching certificate subject name in
libcurl-NSS. Originally reported at:
https://bugzilla.redhat.com/show_bug.cgi?id=516056#c9
Patrick Monnerat (24 Aug 2009)
- Introduced a SYST-based test to properly set-up name format when dealing
with the OS/400 FTP server.
- Fixed an ftp_readresp() bug preventing detection of failing control socket
and causing FTP client to loop forever.
Daniel Stenberg (24 Aug 2009)
- Marc de Bruin pointed out that configure --with-gnutls=PATH didn't work
properly and provided a fix. http://curl.haxx.se/bug/view.cgi?id=2843008
- Eric Wong introduced support for the new option -T. (dot) that makes curl
read stdin in a non-blocking fashion. This also brings back -T- (minus) to
the previous blocking behavior since it could break stuff for people at
times.
Michal Marek (21 Aug 2009)
- With CURLOPT_PROXY_TRANSFER_MODE, avoid sending invalid URLs like
ftp://example.com;type=i if the user specified ftp://example.com without the
slash.
Daniel Stenberg (21 Aug 2009)
- Andre Guibert de Bruet pointed out a missing return code check for a
strdup() that could lead to segfault if it returned NULL. I extended his
suggest patch to now have Curl_retry_request() return a regular return code
and better check that.
- Lots of good work by Krister Johansen, mostly related to pipelining:
Fix SIGSEGV on free'd easy_conn when pipe unexpectedly breaks
Fix data corruption issue with re-connected transfers
Fix use after free if we're completed but easy_conn not NULL
Kamil Dudka (13 Aug 2009)
- Changed NSS code to not ignore the value of ssl.verifyhost and produce more
verbose error messages. Originally reported at:
https://bugzilla.redhat.com/show_bug.cgi?id=516056
Daniel Stenberg (12 Aug 2009)
- Karl Moerder fixed the Makefile.vc* makefiles to include the new file
nonblock.c so that they work fine again
- I expanded test 517 with a bunch of more dates that originate from the
Chrome browser test suite. It turns out most of them get parsed the same
way.
