_ _ ____ _ ___| | | | _ \| | / __| | | | |_) | | | (__| |_| | _ <| |___ \___|\___/|_| \_\_____| Changelog Yang Tse (18 Dec 2007) - MSVC 9.0 (VS2008) does not support Windows build targets prior to WinXP, and makes wrong asumptions of build target when it isn't specified. So, if no build target has been defined we will target WinXP when building curl/libcurl with MSVC 9.0 (VS2008). - (http://curl.haxx.se/mail/archive-2007-12/0039.html) reported and fixed a file truncation problem on Windows build targets triggered when retrying a download with curl. Daniel S (17 Dec 2007) - Mateusz Loskot pointed out that MSVC 9.0 (VS2008) has the pollfd struct and defines in winsock2.h somehow differently than previous versions and that curl 7.17.1 would fail to compile out of the box. Daniel S (13 Dec 2007) - David Wright filed bug report #1849764 (http://curl.haxx.se/bug/view.cgi?id=1849764) with an included fix. He identified a problem for re-used connections that previously had sent Expect: 100-continue and in some situations the subsequent POST (that didn't use Expect:) still had the internal flag set for its use. David's fix (that makes the setting of the flag in every single request unconditionally) is fine and is now used! Daniel S (12 Dec 2007) - Gilles Blanc made the curl tool enable SO_KEEPALIVE for the connections and added the --no-keep-alive option that can disable that on demand. Daniel S (9 Dec 2007) - Andrew Moise filed bug report #1847501 (http://curl.haxx.se/bug/view.cgi?id=1847501) and pointed out a memcpy() that should be memmove() in the convert_lineends() function. Daniel S (8 Dec 2007) - Renamed all internal static functions that had Curl_ prefixes to no longer have them. The Curl_ prefix is exclusively used for library internal global symbols. Static functions can be named anything, except for using Curl_ or curl_ prefixes. This is for consistency and for easier maintainance and overview. - Cleaned up and reformatted the TODO document to look like the FAQ and CONTRIBUTE, which makes nicer web pages - Added test cases 549 and 550 that test CURLOPT_PROXY_TRANSFER_MODE. - Added keywords on a bunch of test cases - Fixed an OOM problem in the curl code that would lead to fclose on a bad handle and crash Daniel S (5 Dec 2007) - Spacen Jasset reported a problem with doing POST (with data read with a callback) over a proxy when NTLM is used as auth with the proxy. The bug also concerned Digest and was limited to using callback only. Spacen worked with us to provide a useful patch. I added the test case 547 and 548 to verify two variations of POST over proxy with NTLM. Daniel S (3 Dec 2007) - Ray Pekowski filed bug report #1842029 (http://curl.haxx.se/bug/view.cgi?id=1842029) in which he identified a problem with SSL session caching that prevent it from working, and provided the associated fix! - Now libcurl (built with OpenSSL) doesn't return error anymore if the remote SSL-based server doesn't present a certificate when the request is told to ignore certificate verification anyway. - Michal Marek introduced CURLOPT_PROXY_TRANSFER_MODE which is used to control the appending of the "type=" thing on FTP URLs when they are passed to a HTTP proxy. Some proxies just don't like that appending (which is done unconditionally in 7.17.1), and some proxies treat binary/ascii transfers better with the appending done! Daniel S (29 Nov 2007) - A bug report on the curl-library list showed a HTTP Digest session going on with a 700+ letter nonce. Previously libcurl only support 127 letter ones and now I bumped it to 1023. - Fixed the resumed FTP upload loop to not require that the read callback returns a full buffer on each invoke. Daniel S (25 Nov 2007) - Added test case 1015 that tests --data-urlencode in multiple ways - Fixed --data-urlencode for when no @ or = are used - Extended the user-agent buffer curl uses, since we can hit the 128 byte border with plenty development libraries used. Like my current set: "curl 7.17.2-CVS (i686-pc-linux-gnu) libcurl/7.17.2-CVS OpenSSL/0.9.8g zlib/1.2.3.3 c-ares/1.5.2-CVS libidn/1.1 libssh2/0.19.0-CVS" Daniel S (24 Nov 2007) - Internal rearrangements, so that the previous struct HandleData is no more. It is now known as SingleRequest and the Curl_transfer_keeper struct within that was remove entirely. This has the upside that there are less duplicate struct members that made it hard to see and remember what struct that was used to store what data. The transfer_keeper thing was once stored on a per-connection basis and then it made sense to have the duplicate info but since it was moved to the SessionHandle (in 7.16.0) it just added weirdness. The SingleRequest struct is used by data that only is valid for this single request. Yang Tse (22 Nov 2007) - Provide a socklen_t definition in curl.h for Win32 API build targets which don't have one. Daniel S (22 Nov 2007) - Alessandro Vesely helped me improve the --data-urlencode's syntax, parser and documentation. Daniel S (21 Nov 2007) - While inspecting the Negotiate code, I noticed how the proxy auth was using the same state struct as the host auth, so both could never be used at the same time! I fixed it (without being able to check) to use two separate structs to allow authentication using Negotiate on host and proxy simultaneously. Daniel S (20 Nov 2007) - Emil Romanus pointed out a bug that made an easy handle get the cookie engine activated when set to use a share (even if the share doesn't share cookies). I fixed it. - Fixed a very long-lasting mprintf() bug that occurred when we did "%.*s%s", since the second %s would then wrongly used the numerical precision argument instead and crash. - Introduced --data-urlencode to the curl tool for easier url encoding of the data sent in a post. Daniel S (18 Nov 2007) - Rob Crittenden fixed SSL connections with NSS done with the multi-interface Daniel S (17 Nov 2007) - Michal Marek made the test suite remember what test servers that fail to start so that subsequent tries are simply skipped. - Andres Garcia made the examples build fine on Windows (mingw + msys) when the lib was built staticly. Daniel S (16 Nov 2007) - Ates Goral identified a problem in http.c:add_buffer_send() when a debug callback was used, as it could wrongly pass on a bad size for the outgoing HTTP header. The bad size would be a very large value as it was a wrapped size_t content. This happened when the whole HTTP request failed to get sent in one single send. http://curl.haxx.se/mail/lib-2007-11/0165.html Daniel S (15 Nov 2007) - Fixed yet another remaining problem with doing SFTP directory listings on a re-used persistent connection. Mentioned by Immanuel Gregoire on the mailing list. - Michal Marek fixed the test suite to better deal with the case when the HTTP ipv6 server can't run. Yang Tse (14 Nov 2007) - Fix a variable potential wrapping in add_buffer() when using absolutely huge send buffer sizes. Daniel S (13 Nov 2007) - Fixed a remaining problem with doing SFTP directory listings on a re-used persistent connection. Mentioned by Immanuel Gregoire on the mailing list. Daniel S (12 Nov 2007) - Bug report #1830637 (http://curl.haxx.se/bug/view.cgi?id=1830637), which was forwarded from the Gentoo bug tracker by Daniel Black and was originally submitted by Robin Johnson, pointed out that libcurl would do bad memory references when it failed and bailed out before the handler thing was setup. My fix is not done like the provided patch does it, but instead I make sure that there's never any chance for a NULL pointer in that struct member. Yang Tse (10 Nov 2007) - Vikram Saxena (http://curl.haxx.se/mail/lib-2007-11/0096.html) pointed out that the pollfd struct was being multi defined when using VS2008. This is now fixed in /curl/lib/select.h Daniel S (8 Nov 2007) - Bug report #1823487 (http://curl.haxx.se/bug/view.cgi?id=1823487) pointed out that SFTP requests didn't use persistent connections. Neither did SCP ones. I gave the SSH code a good beating and now both SCP and SFTP should use persistent connections fine. I also did a bunch of indent changes as well as a bug fix for the "keyboard interactive" auth. Dan F (6 Nov 2007) - Improved telnet support by drastically reducing the number of write callbacks needed to pass a buffer to the user. Instead one per byte it is now as little as one per segment. Yang Tse (6 Nov 2007) - Bug report #1824894 (http://curl.haxx.se/bug/view.cgi?id=1824894) pointed out a problem in curl.h when building C++ apps with MSVC. To fix it, the inclusion of header files in curl.h is moved outside of the C++ extern "C" linkage block. Daniel S (1 Nov 2007) - Toby Peterson patched a memory problem in the command line tool that happened when a user had a home dir as an empty string. curl would then do free() on a wrong area. Dan F (1 Nov 2007) - Fixed curl-config --features to not display libz when it wasn't used due to a missing header file. Dan F (31 October 2007) - Fixed the output of curl-config --protocols which showed SCP and SFTP always, except when --without-libssh2 was given - Added test cases 1013 and 1014 to check that curl-config --protocols and curl-config --features matches the output of curl --version Dan F (30 October 2007) - Fixed an OOM problem with file: URLs - Moved Curl_file_connect into the protocol handler struct Dan F (29 October 2007) - Added test case 546 to check that subsequent FTP transfers work after a failed one using the multi interface Daniel S (29 October 2007) - Based on one of those bug reports that are intercepted by a distro's bug tracker (https://bugzilla.redhat.com/show_bug.cgi?id=316191), I now made curl-config --features and --protocols show the correct output when built with NSS. Version 7.17.1 (29 October 2007) Dan F (25 October 2007) - Added the --static-libs option to curl-config Daniel S (25 October 2007) - Made libcurl built with NSS possible to ignore the peer verification. Previously it would fail if the ca bundle wasn't present, even if the code ignored the verification results. Patrick M (25 October 2007) - Fixed test server to allow null bytes in binary posts. _ Added tests 35, 544 & 545 to check binary data posts, both static (in place) and dynamic (copied). Daniel S (25 October 2007) - Michal Marek fixed the test script to be able to use valgrind even when the lib is built shared with libtool. - Fixed a few memory leaks when the same easy handle is re-used to request URLs with different protocols. FTP and TFTP related leaks. Caught thanks to Dan F's new test cases. Dan F (24 October 2007) - Fixed the test FTP and TFTP servers to support the >10000 test number notation - Added test cases 2000 through 2003 which test multiple protocols using the same easy handle - Fixed the filecheck: make target to work outside the source tree Daniel S (24 October 2007) - Vladimir Lazarenko pointed out that we should do some 'mt' magic when building with VC8 to get the "manifest" embedded to make fine stand-alone binaries. The maketgz and the src/Makefile.vc6 files were adjusted accordingly. Daniel S (23 October 2007) - Bug report #1812190 (http://curl.haxx.se/bug/view.cgi?id=1812190) points out that libcurl tried to re-use connections a bit too much when using non-SSL protocols tunneled over a HTTP proxy. Daniel S (22 October 2007) - Michal Marek forwarded the bug report https://bugzilla.novell.com/show_bug.cgi?id=332917 about a HTTP redirect to FTP that caused memory havoc. His work together with my efforts created two fixes: #1 - FTP::file was moved to struct ftp_conn, because is has to be dealt with at connection cleanup, at which time the struct HandleData could be used by another connection. Also, the unused char *urlpath member is removed from struct FTP. #2 - provide a Curl_reset_reqproto() function that frees data->reqdata.proto.* on connection setup if needed (that is if the SessionHandle was used by a different connection). A long-term goal is of course to somehow get rid of how the reqdata struct is used, as it is too error-prone. - Bug report #1815530 (http://curl.haxx.se/bug/view.cgi?id=1815530) points out that specifying a proxy with a trailing slash didn't work (unless it also contained a port number). Patrick M (15 October 2007) - Fixed the dynamic CURLOPT_POSTFIELDS problem: this option is now static again and option CURLOPT_COPYPOSTFIELDS has been added to support dynamic mode. Patrick M (12 October 2007) - Added per-protocol callback static tables, replacing callback ptr storage in the connectdata structure by a single handler table ptr. Dan F (11 October 2007) - Fixed the -l option of runtests.pl - Added support for skipping tests based on key words. Daniel S (9 October 2007) - Michal Marek removed the no longer existing return codes from the curl.1 man page. Daniel S (7 October 2007) - Known bug #47, which confused libcurl if doing NTLM auth over a proxy with a response that was larger than 16KB is now improved slightly so that now the restriction at 16KB is for the headers only and it should be a rare situation where the response-headers exceed 16KB. Thus, I consider #47 fixed and the header limitation is now known as known bug #48. Daniel S (5 October 2007) - Michael Wallner made the CULROPT_COOKIELIST option support a new magic string: "FLUSH". Using that will cause libcurl to flush its cookies to the CURLOPT_COOKIEJAR file. - The new file docs/libcurl/ABI describes how we view ABI breakages, soname bumps and what the version number's significance to all that is. Daniel S (4 October 2007) - I enabled test 1009 and made the --local-port use a wide range to reduce the risk of failures. - Kim Rinnewitz reported that --local-port didn't work with TFTP transfers. This happened because the tftp code always uncondionally did a bind() without caring if one already had been done and then it failed. I wrote a test case (1009) to verify this, but it is a bit error-prone since it will have to pick a fixed local port number and since the tests are run on so many different hosts in different situations I'll add it in disabled state. Yang Tse (3 October 2007) - Fixed issue related with the use of ares_timeout() result. Daniel S (3 October 2007) - Alexey Pesternikov introduced CURLOPT_OPENSOCKETFUNCTION and CURLOPT_OPENSOCKETDATA to set a callback that allows an application to replace the socket() call used by libcurl. It basically allows the app to change address, protocol or whatever of the socket. - I renamed the CURLE_SSL_PEER_CERTIFICATE error code to CURLE_PEER_FAILED_VERIFICATION (standard CURL_NO_OLDIES style), and made this return code get used by the previous SSH MD5 fingerprint check in case it fails. - Based on a patch brought by Johnny Luong, libcurl now offers CURLOPT_SSH_HOST_PUBLIC_KEY_MD5 and the curl tool --hostpubmd5. They both make the SCP or SFTP connection verify the remote host's md5 checksum of the public key before doing a connect, to reduce the risk of a man-in-the-middle attack. Daniel S (2 October 2007) - libcurl now handles chunked-encoded CONNECT responses Daniel S (1 October 2007) - Alex Fishman reported a curl_easy_escape() problem that was made the function do wrong on all input bytes that are >= 0x80 (decimal 128) due to a signed / unsigned mistake in the code. I fixed it and added test case 543 to verify. Daniel S (29 September 2007) - Immanuel Gregoire fixed a problem with persistent transfers over SFTP. Daniel S (28 September 2007) - Adapted the c-ares code to the API change c-ares 1.5.0 brings in the notifier callback(s). Dan F (26 September 2007) - Enabled a few more gcc warnings with --enable-debug. Renamed a few variables to avoid shadowing global declarations. Daniel S (26 September 2007) - Philip Langdale provided the new CURLOPT_POST301 option for curl_easy_setopt() that alters how libcurl functions when following redirects. It makes libcurl obey the RFC2616 when a 301 response is received after a non-GET request is made. Default libcurl behaviour is to change method to GET in the subsequent request (like it does for response code 302 - because that's what many/most browsers do), but with this CURLOPT_POST301 option enabled it will do what the spec says and do the next request using the same method again. I.e keep POST after 301. The curl tool got this option as --post301 Test case 1011 and 1012 were added to verify. - Max Katsev reported that when doing a libcurl FTP request with CURLOPT_NOBODY enabled but not CURLOPT_HEADER, libcurl wouldn't do TYPE before it does SIZE which makes it less useful. I walked over the code and made it do this properly, and added test case 542 to verify it. Daniel S (24 September 2007) - Immanuel Gregoire fixed KNOWN_BUGS #44: --ftp-method nocwd did not handle URLs ending with a slash properly (it should list the contents of that directory). Test case 351 brought back and also test 1010 was added. Daniel S (21 September 2007) - Mark Davies fixed Negotiate authentication over proxy, and also introduced the --proxy-negotiate command line option to allow a user to explicitly select it. Daniel S (19 September 2007) - Rob Crittenden provided an NSS update with the following highlights: o It looks for the NSS database first in the environment variable SSL_DIR, then in /etc/pki/nssdb, then it initializes with no database if neither of those exist. o If the NSS PKCS#11 libnspsem.so driver is available then PEM files may be loaded, including the ca-bundle. If it is not available then only certificates already in the NSS database are used. o Tries to detect whether a file or nickname is being passed in so the right thing is done o Added a bit of code to make the output more like the OpenSSL module, including displaying the certificate information when connecting in verbose mode o Improved handling of certificate errors (expired, untrusted, etc) The libnsspem.so PKCS#11 module is currently only available in Fedora 8/rawhide. Work will be done soon to upstream it. The NSS module will work with or without it, all that changes is the source of the certificates and keys. Daniel S (18 September 2007) - Immanuel Gregoire pointed out that public key SSH auth failed if no public/private key was specified and there was no HOME environment variable, and then it didn't continue to try the other auth methods. Now it will instead try to get the files id_dsa.pub and id_dsa from the current directory if none of the two conditions were met. Dan F (17 September 2007) - Added hooks to the test suite to make it possible to test a curl running on a remote host. - Changed some FTP tests to validate the format of the PORT and EPRT commands sent by curl, if not the addresses themselves. Daniel S (15 September 2007) - Michal Marek made libcurl automatically append ";type=" when using HTTP proxies for FTP urls. - Günter Knauf fixed LDAP builds in the Windows makefiles and fixed LDAPv3 support on Windows. Dan F (13 September 2007) - Added LDAPS, SCP and SFTP to curl-config --protocols. Removed and fixed some AC_SUBST configure entries. Version 7.17.0 (13 September 2007) Daniel S (12 September 2007) - Bug report #1792649 (http://curl.haxx.se/bug/view.cgi?id=1792649) pointed out a problem with doing an empty upload over FTP on a re-used connection. I added test case 541 to reproduce it and to verify the fix. - I noticed while writing test 541 that the FTP code wrongly did a CWD on the second transfer as it didn't store and remember the "" path from the previous transfer so it would instead CWD to the entry path as stored. This worked, but did a superfluous command. Thus, test case 541 now also verifies this fix. Dan F (5 September 2007) - Added test case 1007 to test permission problem when uploading with TFTP (to validate bug #1790403). - TFTP now reports the "not defined" TFTP error code 0 as an error, not success. Daniel S (5 September 2007) - Continued the work on a fix for #1779054 (http://curl.haxx.se/bug/view.cgi?id=1779054). My previous fix from August 24 was not complete (either) but could accidentally "forget" parts of a server response which led to faulty server response time-out errors. Dan F (5 September 2007) - Minix doesn't support getsockopt on UDP sockets or send/recv on TCP sockets. Dan F (31 August 2007) - Made some of the error strings returned by the *strerror functions more generic, and more consistent with each other. - Renamed the curl_ftpssl enum to curl_usessl and its enumerated constants, creating macros for backward compatibility: CURLFTPSSL_NONE => CURLUSESSL_NONE CURLFTPSSL_TRY => CURLUSESSL_TRY CURLFTPSSL_CONTROL => CURLUSESSL_CONTROL CURLFTPSSL_ALL => CURLUSESSL_ALL CURLFTPSSL_LAST => CURLUSESSL_LAST Dan F (30 August 2007) - Renamed several libcurl error codes and options to make them more general and allow reuse by multiple protocols. Several unused error codes were removed. In all cases, macros were added to preserve source (and binary) compatibility with the old names. These macros are subject to removal at a future date, but probably not before 2009. An application can be tested to see if it is using any obsolete code by compiling it with the CURL_NO_OLDIES macro defined. The following unused error codes were removed: CURLE_BAD_CALLING_ORDER CURLE_BAD_PASSWORD_ENTERED CURLE_FTP_CANT_RECONNECT CURLE_FTP_COULDNT_GET_SIZE CURLE_FTP_COULDNT_SET_ASCII CURLE_FTP_USER_PASSWORD_INCORRECT CURLE_FTP_WEIRD_USER_REPLY CURLE_FTP_WRITE_ERROR CURLE_LIBRARY_NOT_FOUND CURLE_MALFORMAT_USER CURLE_OBSOLETE CURLE_SHARE_IN_USE CURLE_URL_MALFORMAT_USER The following error codes were renamed: CURLE_FTP_ACCESS_DENIED => CURLE_REMOTE_ACCESS_DENIED CURLE_FTP_COULDNT_SET_BINARY => CURLE_FTP_COULDNT_SET_TYPE CURLE_FTP_SSL_FAILED => CURLE_USE_SSL_FAILED CURLE_FTP_QUOTE_ERROR => CURLE_QUOTE_ERROR CURLE_TFTP_DISKFULL => CURLE_REMOTE_DISK_FULL CURLE_TFTP_EXISTS => CURLE_REMOTE_FILE_EXISTS CURLE_HTTP_RANGE_ERROR => CURLE_RANGE_ERROR The following options were renamed: CURLOPT_SSLKEYPASSWD => CURLOPT_KEYPASSWD CURLOPT_FTPAPPEND => CURLOPT_APPEND CURLOPT_FTPLISTONLY => CURLOPT_DIRLISTONLY CURLOPT_FTP_SSL => CURLOPT_USE_SSL A few more changes will take place with the next SONAME bump of the library. These are documented in docs/TODO - Documented some newer error codes in libcurl-error(3) - Added more accurate error code returns from SFTP operations. Added test case 615 to test an SFTP upload failure. Dan F (28 August 2007) - Some minor internal type and const changes based on a splint scan. Daniel S (24 August 2007) - Bug report #1779054 (http://curl.haxx.se/bug/view.cgi?id=1779054) pointed out that libcurl didn't deal with large responses from server commands, when the single response was consisting of multiple lines but of a total size of 16KB or more. Dan Fandrich improved the ftp test script and provided test case 1006 to repeat the problem, and I fixed the code to make sure this new test case runs fine. Patrick M (23 August 2007) - OS/400 port: new files lib/config-os400.h lib/setup-os400.h packages/OS400/*. See packages/OS400/README.OS400. Daniel S (23 August 2007) - Bug report #1779751 (http://curl.haxx.se/bug/view.cgi?id=1779751) pointed out that doing first a file:// upload and then an FTP upload crashed libcurl or at best caused furious valgrind complaints. Fixed now! Daniel S (22 August 2007) - Bug report #1779054 (http://curl.haxx.se/bug/view.cgi?id=1779054) pointed out that libcurl didn't deal with very long (>16K) FTP server response lines properly. Starting now, libcurl will chop them off (thus the client app will not get the full line) but survive and deal with them fine otherwise. Test case 1003 was added to verify this. Daniel S (20 August 2007) - Based on a patch by Christian Vogt, the FTP code now sets the upcoming download transfer size much earlier to be possible to get read with CURLINFO_CONTENT_LENGTH_DOWNLOAD as soon as possible. This is very much in a similar spirit to the HTTP size change from August 11 2007. Daniel S (18 August 2007) - Robson Braga Araujo filed bug report #1776232 (http://curl.haxx.se/bug/view.cgi?id=1776232) about libcurl calling Curl_client_write(), passing on a const string that the caller may not modify and yet it does (on some platforms). - Robson Braga Araujo filed bug report #1776235 (http://curl.haxx.se/bug/view.cgi?id=1776235) about ftp requests with NOBODY on a directory would do a "SIZE (null)" request. This is now fixed and test case 1000 was added to verify. Daniel S (17 August 2007) - Song Ma provided a patch that cures a problem libcurl has when doing resume HTTP PUT using Digest authentication. Test case 5320 and 5322 were also added to verify the functionality. Daniel S (14 August 2007) - Andrew Wansink provided an NTLM bugfix: in the case the server sets the flag NTLMFLAG_NEGOTIATE_UNICODE, we need to filter it off because libcurl doesn't UNICODE encode the strings it packs into the NTLM authenticate packet. Daniel S (11 August 2007) - Allen Pulsifer provided a patch that makes libcurl set the expected download size earlier when doing HTTP downloads, so that applications and the progress meter etc know get the info earlier in the flow than before. - Patrick Monnerat modified the LDAP code and approach in curl. Starting now, the configure script checks for openldap and friends and we link with those libs just like we link all other third party libraries, and we no longer dlopen() those libraries. Our private header file lib/ldap.h was renamed to lib/curl_ldap.h due to this. I set a tag in CVS (curl-7_17_0-preldapfix) just before this commit, just in case. Dan F (8 August 2007) - Song Ma noted a zlib memory leak in the illegal compressed header countermeasures code path. Daniel S (4 August 2007) - Patrick Monnerat fixed curl_easy_escape() and curlx_strtoll() to work on non-ASCII systems. Daniel S (3 August 2007) - I cut out support for libssh2 versions older than 0.16 to make our code a lot simpler, and to avoid getting trouble with the LIBSSH2_APINO define that 1) didn't work properly since it was >32 bits and 2) is removed in libssh2 0.16... Daniel S (2 August 2007) - Scott Cantor filed bug report #1766320 (http://curl.haxx.se/bug/view.cgi?id=1766320) pointing out that the libcurl code accessed two curl_easy_setopt() options (CURLOPT_DNS_CACHE_TIMEOUT and CURLOPT_DNS_USE_GLOBAL_CACHE) as ints even though they're documented to be passed in as longs, and that makes a difference on 64 bit architectures. - Dmitriy Sergeyev reported a regression: resumed file:// transfers broke after 7.16.2. This is much due to the different treatment file:// gets internally, but now I added test 231 to make it less likely to happen again without us noticing! Daniel S (1 August 2007) - Patrick Monnerat and I modified libcurl so that now it *copies* all strings passed to it with curl_easy_setopt()! Previously it has always just refered to the data, forcing the user to keep the data around until libcurl is done with it. That is now history and libcurl will instead clone the given strings and keep private copies. This is also part of Patrick Monnerat's OS/400 port. Due to this being a somewhat interesting change API wise, I've decided to bump the version of the upcoming release to 7.17.0. Older applications will of course not notice this change nor do they have to care, but new applications can be written to take advantage of this. - Greg Morse reported a problem with POSTing using ANYAUTH to a server requiring NTLM, and he provided test code and a test server and we worked out a bug fix. We failed to count sent body data at times, which then caused internal confusions when libcurl tried to send the rest of the data in order to maintain the same connection alive. Daniel S (31 July 2007) - Peter O'Gorman pointed out (and fixed) that the non-blocking check in configure made libcurl use blocking sockets on AIX 4 and 5, while that wasn't the intention. Daniel S (29 July 2007) - Jayesh A Shah filed bug report #1759542 (http://curl.haxx.se/bug/view.cgi?id=1759542) identifying a rather serious problem with FTPS: libcurl closed the data connection socket and then later in the flow it would call the SSL layer to do SSL shutdown which then would use a socket that had already been closed - so if the application had opened a new one in the mean time, libcurl could send gibberish that way! I worked with Greg Zavertnik to properly diagnose and fix this. The fix affects code for all SSL libraries we support, but it has only been truly verified to work fine for the OpenSSL version. The others have only been code reviewed. Daniel S (23 July 2007) - Implemented the parts of Patrick Monnerat's OS/400 patch that introduces support for the OS/400 Secure Sockets Layer library. Dan F (23 July 2007) - Implemented only the parts of Patrick Monnerat's OS/400 patch that renamed some few internal identifiers to avoid conflicts, which could be useful on other platforms. Daniel S (22 July 2007) - HTTP Digest bug fix by Chris Flerackers: Scenario - Perfoming a POST request with body - With authentication (only Digest) - Re-using a connection libcurl would send a HTTP POST with an Authorization header but without body. Our server would return 400 Bad Request in that case (because authentication passed, but the body was empty). Cause 1) http_digest.c -> Curl_output_digest - Updates allocptr.userpwd/allocptr.proxyuserpwd *only* if d->nonce is filled in (and no errors) - authp->done = TRUE if d->nonce is filled in 2) http.c -> Curl_http - *Always* uses allocptr.userpwd/allocptr.proxyuserpwd if not NULL 3) http.c -> Curl_http, Curl_http_output_auth So what happens is that Curl_output_digest cannot yet update the Authorization header (allocptr.userpwd) which results in authhost->done=0 -> authhost->multi=1 -> conn->bits.authneg = TRUE. The body is not added. *However*, allocptr.userpwd is still used when building the request - Added test case 354 that makes a simple FTP retrieval without password, which verifies the bug fix in #1757328. Daniel S (21 July 2007) - To allow more flexibility in FTP test cases, I've removed the enforced states from the test server code as they served no real purpose. The test server is here to serve for the test cases, not to attempt to function as a real server! While at it, I modified test case 141 to better test and verify curl -I on a single FTP file. Daniel S (20 July 2007) - James Housley fixed the SFTP PWD command to work. - Ralf S. Engelschall filed bug report #1757328 (http://curl.haxx.se/bug/view.cgi?id=1757328) and submitted a patch. It turns out we broke login to FTP servers that don't require (nor understand) PASS after the USER command. The breakage was done as part of the krb5 commit so a krb-using person needs to verify that the current version now works or if we need to fix it (in a different way of course). Dan F (17 July 2007) - Fixed test cases 613 and 614 by improving the log postprocessor to handle a new directory listing format that newer libssh2's can provide. This is probably NOT sufficient to handle all directory listing formats that server's can provide, and should be revisited. Daniel S (17 July 2007) - Daniel Johnson fixed a bug in how libssh2_session_last_error() was used, in two places. - Jofell Gallardo posted a libcurl log using FTP that exposed a bug which made a control connection that was deemed "dead" to yet be re-used in a following request. Daniel S (13 July 2007) - Colin Hogben filed bug report #1750274 (http://curl.haxx.se/bug/view.cgi?id=1750274) and submitted a patch for the case where libcurl did a connect attempt to a non-listening port and didn't provide a human readable error string back. - Daniel Cater fixes: 1 - made 'make vc8' work on windows. 2 - made libcurl itself built with CURL_NO_OLDIES defined (which doesn't define the symbols for backwards source compatibility) 3 - updated libcurl-errors.3 4 - added CURL_DISABLE_TFTP to docs/INSTALL Daniel S (12 July 2007) - Made the krb5 code build with Heimdal's GSSAPI lib. Dan F (12 July 2007) - Compile most of the example apps in docs/examples when doing a 'make check'. Fixed some compile warnings and errors in those examples. - Removed the example program ftp3rdparty.c since libcurl doesn't support 3rd party FTP transfers any longer. Daniel S (12 July 2007) - Shmulik Regev found an (albeit rare) case where the proxy CONNECT operation could in fact get stuck in an endless loop. - Made CURLOPT_SSL_VERIFYHOST set to 1 acts as described in the documentation: fail to connect if there is no Common Name field found in the remote cert. We should deprecate the support for this set to 1 anyway soon, since the feature is pointless and most likely never really used by anyone. Daniel S (11 July 2007) - Shmulik Regev fixed a bug with transfer-encoding skipping during the 407 error pages for proxy authentication. - Giancarlo Formicuccia reported and fixed a problem with a closed connection to a proxy during CONNECT auth negotiation. Dan F (10 July 2007) - Fixed a curl memory leak reported by Song Ma with a modified version of the patch he suggested. Added his test case as test289 to verify. - Force the time zone to GMT in the cookie tests in case the user is using one of the so-called 'right' time zones that take into account leap seconds, which causes the tests to fail (as reported by Daniel Black in bug report #1745964). Version 7.16.4 (10 July 2007) Daniel S (10 July 2007) - Kees Cook notified us about a security flaw (http://curl.haxx.se/docs/adv_20070710.html) in which libcurl failed to properly reject some outdated or not yet valid server certificates when built with GnuTLS. Kees also provided the patch. James H (5 July 2007) - Gavrie Philipson provided a patch that will use a more specific error message for an scp:// upload failure. If libssh2 has his matching patch, then the error message return by the server will be used instead of a more generic error. Daniel S (1 July 2007) - Thomas J. Moore provided a patch that introduces Kerberos5 support in libcurl. This also makes the options change name to --krb (from --krb4) and CURLOPT_KRBLEVEL (from CURLOPT_KRB4LEVEL) but the old names are still - Song Ma helped me verify and extend a fix for doing FTP over a SOCKS4/5 proxy. Daniel S (27 June 2007) - James Housley: Add two new options for the SFTP/SCP/FILE protocols: CURLOPT_NEW_FILE_PERMS and CURLOPT_NEW_DIRECTORY_PERMS. These control the premissions for files and directories created on the remote server. CURLOPT_NEW_FILE_PERMS defaults to 0644 and CURLOPT_NEW_DIRECTORY_PERMS defaults to 0755 - I corrected the 10-at-a-time.c example and applied a patch for it by James Bursa. Daniel S (26 June 2007) - Robert Iakobashvili re-arranged the internal hash code to work with a custom hash function for different hashes, and also expanded the default size for the socket hash table used in multi handles to greatly enhance speed when very many connections are added and the socket API is used. - James Housley made the CURLOPT_FTPLISTONLY mode work for SFTP directory listings as well Daniel S (25 June 2007) - Adjusted how libcurl treats HTTP 1.1 responses without content-lenth or chunked encoding (that also lacks "Connection: close"). It now simply assumes that the connection WILL be closed to signal the end, as that is how RFC2616 section 4.4 point #5 says we should behave. Version 7.16.3 (25 June 2007) Daniel S (23 June 2007) - As reported by "Tro" in http://curl.haxx.se/mail/lib-2007-06/0161.html and http://curl.haxx.se/mail/lib-2007-06/0238.html, libcurl didn't properly do no-body requests on FTP files on re-used connections properly, or at least it didn't provide the info back in the header callback properly in the subsequent requests. Daniel S (21 June 2007) - Gerrit Bruchhäuser pointed out a warning that the Intel(R) Thread Checker tool reports and it was indeed a legitimate one and it is one fixed. It was a use of a share without doing the proper locking first. Daniel S (20 June 2007) - Adam Piggott filed bug report #1740263 (http://curl.haxx.se/bug/view.cgi?id=1740263). Adam discovered that when getting a large amount of URLs with curl, they were fetched slower and slower... which turned out to be because the --libcurl data collecting which wrongly always was enabled, but no longer is... Daniel S (18 June 2007) - Robson Braga Araujo filed bug report #1739100 (http://curl.haxx.se/bug/view.cgi?id=1739100) that mentioned that libcurl could not actually list the contents of the root directory of a given FTP server if the login directory isn't root. I fixed the problem and added three test cases (one is disabled for now since I identified KNOWN_BUGS #44, we cannot use --ftp-method nocwd and list ftp directories). Daniel S (14 June 2007) - Shmulik Regev: I've encountered (and hopefully fixed) a problem involving proxy CONNECT requests and easy handles state management. The problem isn't simple to reproduce since it depends on socket state. It only manifests itself when working with non-blocking sockets. Here is the scenario: 1. in multi_runsingle the easy handle is in the CURLM_STATE_WAITCONNECT and calls Curl_protocol_connect 2. in Curl_proxyCONNECT, line 1247, if the socket isn't ready the function returns and conn->bits.tunnel_connecting is TRUE 3. when the call to Curl_protocol_connect returns the protocol_connect flag is false and the easy state is changed to CURLM_STATE_PROTOCONNECT which isn't correct if a proxy is used. Rather CURLM_STATE_WAITPROXYCONNECT should be used. I discovered this while performing an HTTPS request through a proxy (squid) on my local network. The problem caused openssl to fail as it read the proxy response to the CONNECT call ('HTTP/1.0 Established') rather than the SSL handshake (the exact openssl error was 'wrong ssl version' but this isn't very important) - Dave Vasilevsky filed bug report #1736875 (http://curl.haxx.se/bug/view.cgi?id=1736875) almost simultanouesly as Dan Fandrich mentioned a related build problem on the libcurl mailing list: http://curl.haxx.se/mail/lib-2007-06/0131.html. Both problems had the same reason: the definitions of the POLL* defines and the pollfd struct in the libcurl code was depending on HAVE_POLL instead of HAVE_SYS_POLL_H. Daniel S (13 June 2007) - Tom Regner provided a patch and worked together with James Housley, so now CURLOPT_FTP_CREATE_MISSING_DIRS works for SFTP connections as well as FTP ones. - Rich Rauenzahn filed bug report #1733119 (http://curl.haxx.se/bug/view.cgi?id=1733119) and we collaborated on the fix. The problem is that for 64bit HPUX builds, several socket-related functions would still assume int (32 bit) arguments and not socklen_t (64 bit) ones. Daniel S (12 June 2007) - James Housley brought his revamped SSH code that is state-machine driven to really take advantage of the now totally non-blocking libssh2 (in CVS). Dan F (8 June 2007) - Incorporated Daniel Black's test706 and test707 SOCKS test cases. - Fixed a few problems when starting the SOCKS server. - Reverted some recent changes to runtests.pl that weren't compatible with perl 5.0. - Fixed the test harness so that it actually kills the ssh being used as the SOCKS server. Daniel S (6 June 2007) - -s/--silent can now be used to toggle off the silence again if used a second time. Daniel S (5 June 2007) - Added Daniel Black's work that adds the first few SOCKS test cases. I also fixed two minor SOCKS problems to make the test cases run fine. Daniel S (31 May 2007) - Feng Tu made (lib)curl support "upload" resuming work for file:// URLs. Daniel S (30 May 2007) - I modified the 10-at-a-time.c example to transfer 500 downloads in parallel with a c-ares enabled build only to find that it crashed miserably, and this was due to some select()isms left in the code. This was due to API restrictions in c-ares 1.3.x, but with the upcoming c-ares 1.4.0 this is no longer the case so now libcurl runs much better with c-ares and the multi interface with > 1024 file descriptors in use. Extra note: starting now we require c-ares 1.4.0 for asynchronous name resolves. - Added CURLMOPT_MAXCONNECTS which is a curl_multi_setopt() option for setting the maximum size of the connection cache maximum size of the multi handle. Daniel S (27 May 2007) - When working with a problem Stefan Becker had, I found an off-by-one buffer overwrite in Curl_select(). While fixing it, I also improved its performance somewhat by changing calloc to malloc and breaking out of a loop earlier (when possible). Daniel S (25 May 2007) - Rob Crittenden fixed bug #1705802 (http://curl.haxx.se/bug/view.cgi?id=1705802), which was filed by Daniel Black identifying several FTP-SSL test cases fail when we build libcurl with NSS for TLS/SSL. Listed as #42 in KNOWN_BUGS. Daniel S (24 May 2007) - Song Ma filed bug report #1724016 (http://curl.haxx.se/bug/view.cgi?id=1724016) noticing that downloading glob-ranges for TFTP was broken in CVS. Fixed now. - 'mytx' in bug report #1723194 (http://curl.haxx.se/bug/view.cgi?id=1723194) pointed out that the warnf() function in the curl tool didn't properly deal with the cases when excessively long words were used in the string to chop up. Daniel S (22 May 2007) - Andre Guibert de Bruet fixed a memory leak in the function that verifies the peer's name in the SSL certificate when built for OpenSSL. The leak happens for libcurls with CURL_DOES_CONVERSIONS enabled that fail to convert the CN name from UTF8. He also fixed a leak when PKCS #12 parsing failed. Daniel S (18 May 2007) - Feng Tu reported that curl -w did wrong on TFTP transfers in bug report #1715394 (http://curl.haxx.se/bug/view.cgi?id=1715394), and the transfer-related info "variables" were indeed overwritten with zeroes wrongly and have now been adjusted. The upload size still isn't accurate. Daniel S (17 May 2007) - Feng Tu pointed out a division by zero error in the TFTP connect timeout code for timeouts less than five seconds, and also provided a fix for it. Bug report #1715392 (http://curl.haxx.se/bug/view.cgi?id=1715392) Dan F (16 May 2007) - Added support for compiling under Minix 3.1.3 using ACK. Dan F (14 May 2007) - Added SFTP directory listing test case 613. - Added support for quote commands before a transfer using SFTP and test case 614. - Changed the post-quote commands to occur after the transferred file is closed. - Allow SFTP quote commands chmod, chown, chgrp to set a value of 0. Dan F (9 May 2007) - Kristian Gunstone fixed a problem where overwriting an uploaded file with sftp didn't truncate it first, which would corrupt the file if the new file was shorter than the old. Dan F (8 May 2007) - Added FTPS test cases 406 and 407 Daniel S (8 May 2007) - CURLE_FTP_COULDNT_STOR_FILE is now known as CURLE_UPLOAD_FAILED. This is because I just made SCP uploads return this value if the file size of the upload file isn't given with CURLOPT_INFILESIZE*. Docs updated to reflect this news, and a define for the old name was added to the public header file. Daniel S (7 May 2007) - James Bursa fixed a bug in the multi handle code that made the connection cache grow a bit too much, beyond the normal 4 * easy_handles. Daniel S (2 May 2007) - Anders Gustafsson remarked that requiring CURLOPT_HTTP_VERSION set to 1.0 when CURLOPT_HTTP200ALIASES is used to avoid the problem mentioned below is not very nice if the client wants to be able to use _either_ a HTTP 1.1 server or one within the aliases list... so starting now, libcurl will simply consider 200-alias matches the to be HTTP 1.0 compliant. - Tobias Rundström reported a problem they experienced with xmms2 and recent libcurls, which turned out to be the 25-nov-2006 change which treats HTTP responses without Content-Length or chunked encoding as without bodies. We now added the conditional that the above mentioned response is only without body if the response is HTTP 1.1. - Jeff Pohlmeyer improved the hiperfifo.c example to use the CURLMOPT_TIMERFUNCTION callback option. - Set the timeout for easy handles to expire really soon after addition or when CURLM_CALL_MULTI_PERFORM is returned from curl_multi_socket*/perform, to make applications using only curl_multi_socket() to properly function when adding easy handles "on the fly". Bug report and test app provided by Michael Wallner. Dan F (30 April 2007) - Improved the test harness to allow running test servers on other than the default port numbers, allowing more than one test suite to run simultaneously on the same host. Daniel S (28 April 2007) - Peter O'Gorman fixed libcurl to not init GnuTLS as early as we did before, since it then inits libgcrypt and libgcrypt is being evil and EXITS the application if it fails to get a fine random seed. That's really not a nice thing to do by a library. - Frank Hempel fixed a curl_easy_duphandle() crash on a handle that had been removed from a multi handle, and then fixed another flaw that prevented curl_easy_duphandle() to work even after the first fix - the handle was still marked as using the multi interface. Daniel S (26 April 2007) - Peter O'Gorman found a problem with SCP downloads when the downloaded file was 16385 bytes (16K+1) and it turned out we didn't properly always "suck out" all data from libssh2. The effect being that libcurl would hang on the socket waiting for data when libssh2 had in fact already read it all... Dan F (25 April 2007) - Added support in runtests.pl for "!n" test numbers to disable individual tests. Changed -t to only keep log files around when -k is specified, to have the same behaviour as without -t. Daniel S (25 April 2007) - Sonia Subramanian brought our attention to a problem that happens if you set the CURLOPT_RESUME_FROM or CURLOPT_RANGE options and an existing connection in the connection cache is closed to make room for the new one when you call curl_easy_perform(). It would then wrongly free range-related data in the connection close funtion. Yang Tse (25 April 2007) - Steve Little fixed compilation on VMS 64-bit mode Daniel S (24 April 2007) - Robert Iakobashvili made the 'master_buffer' get allocated first once it is can/will be used as it then makes the common cases save 16KB of data for each easy handle that isn't used for pipelining. Dan F (23 April 2007) - Added support to the test harness. - Added tests 610-612 to test more SFTP post-quote commands. Daniel S (22 April 2007) - Song Ma's warning if -r/--range is given with a "bad" range, also noted in the man page now. - Daniel Black filed bug #1705177 (http://curl.haxx.se/bug/view.cgi?id=1705177) where --without-ssl --with-gnutl outputs a warning about SSL not being enabled even though GnuTLS was found and used. Daniel S (21 April 2007) - Daniel Black filed bug #1704675 (http://curl.haxx.se/bug/view.cgi?id=1704675) identifying a double-free problem in the SSL-dealing layer, telling GnuTLS to free NULL credentials on closedown after a failure and a bad #ifdef for NSS when closing down SSL. Yang Tse (20 April 2007) - Save one call to curlx_tvnow(), which calls gettimeofday(), in each of Curl_socket_ready(), Curl_poll() and Curl_select() when these are called with a zero timeout or a timeout value indicating a blocking call should be performed. Daniel S (18 April 2007) - James Housley made SFTP uploads use libssh2's non-blocking API - Prevent the internal progress meter from updating more frequently than once per second. Dan F (17 April 2007) - Added test cases 296, 297 and 298 to test --ftp-method handling Daniel S (16 April 2007) - Robert Iakobashvil added curl_multi_socket_action() to libcurl, which is a function that deprecates the curl_multi_socket() function. Using the new function the application tell libcurl what action that was found in the socket that it passes in. This gives a significant performance boost as it allows libcurl to avoid a call to poll()/select() for every call to curl_multi_socket*(). I added a define in the public curl/multi.h header file that will make your existing application automatically use curl_multi_socket_action() instead of curl_multi_socket() when you recompile. But of course you'll get better performance if you adjust your code manually and actually pass in the correct action bitmask to this function. Daniel S (14 April 2007) - Jay Austin added "DH PARAMETERS" to the stunnel.pem certificate for the test suite to make stunnel run better in some (most?) environments. Dan F (13 April 2007) - Added test cases 294 and 295 to test --ftp-account handling - Improved handling of out of memory in ftp. Yang Tse (13 April 2007) - Fix test case 534 which started to fail 2007-04-13 due to the existance of a new host on the net with the same silly domain the test was using for a host which was supposed not to exist. Daniel S (12 April 2007) - Song Ma found a memory leak in the if2ip code if you pass in an interface name longer than the name field of the ifreq struct (typically 6 bytes), as then it wouldn't close the used dummy socket. Bug #1698974 (http://curl.haxx.se/bug/view.cgi?id=1698974) Version 7.16.2 (11 April 2007) Yang Tse (10 April 2007) - Ravi Pratap provided some fixes for HTTP pipelining - configure script will ignore --enable-sspi option for non-native Windows. Daniel S (9 April 2007) - Nick Zitzmann did ssh.c cleanups Daniel S (3 April 2007) - Rob Jones fixed better #ifdef'ing for a bunch of #include lines. Daniel S (2 April 2007) - Nick Zitzmann made the CURLOPT_POSTQUOTE option work for SFTP as well. The accepted commands are as follows: chgrp (gid) (path) Changes the group ID of the file or directory at (path) to (gid). (gid) must be a number. chmod (perms) (path) Changes the permissions of the file or directory at (path) to (perms). (perms) must be a number in the format used by the chmod Unix command. chown (uid) (path) Changes the user ID of the file or directory at (path) to (uid). (uid) must be a number. ln (source) (dest) Creates a symbolic link at (dest) that points to the file located at (source). mkdir (path) Creates a new directory at (path). rename (source) (dest) Moves the file or directory at (source) to (dest). rm (path) Deletes the file located at (path). rmdir (path) Deletes the directory located at (path). This command will raise an error if the directory is not empty. symlink (source) (dest) Same as ln. Daniel S (1 April 2007) - Robert Iakobashvili made curl_multi_remove_handle() a lot faster when many easy handles are added to a multi handle, by avoiding the looping over all the handles to find which one to remove. - Matt Kraai provided a patch that makes curl build on QNX 6 fine again. Daniel S (31 March 2007) - Fixed several minor issues detected by the coverity.com scanner. - "Pixel" fixed a problem that appeared when you used -f with user+password embedded in the URL. Dan F (29 March 2007) - Don't tear down the ftp connection if the maximum filesize was exceeded and added tests 290 and 291 to check. - Added ftps upload and SSL required tests 401 and 402. - Send an EOF message before closing an SCP channel, as recommended by RFC4254. Enable libssh2 tracing when ssh debugging is turned on. Yang Tse (27 March 2007) - Internal function Curl_select() renamed to Curl_socket_ready() New Internal wrapper function Curl_select() around select (2), it uses poll() when a fine poll() is available, so now libcurl can be built without select() support at all if a fine poll() is available. Daniel S (25 March 2007) - Daniel Johnson fixed multi code to traverse the easy handle list properly. A left-over bug from the February 21 fix. Dan F (23 March 2007) - Added --pubkey option to curl and made --key also work for SCP/SFTP, plus made --pass work on an SSH private key as well. - Changed the test harness to attempt to gracefully shut down servers before resorting to the kill -9 hammer. - Added test harness infrastructure to support scp/sftp tests, using OpenSSH as the server. - Fixed a memory leak when specifying a proxy with a file: URL. Yang Tse (20 March 2007) - Fixed: When a signal was caught awaiting for an event using Curl_select() or Curl_poll() with a non-zero timeout both functions would restart the specified timeout. This could even lead to the extreme case that if a signal arrived with a frecuency lower to the specified timeout neither function would ever exit. Added experimental symbol definition check CURL_ACKNOWLEDGE_EINTR in Curl_select() and Curl_poll(). When compiled with CURL_ACKNOWLEDGE_EINTR defined both functions will return as soon as a signal is caught. Use it at your own risk, all calls to these functions in the library should be revisited and checked before fully supporting this feature. Yang Tse (19 March 2007) - Bryan Henderson fixed the progress function so that it can get called more frequently allowing same calling frecuency for the client progress callback. Dan F (15 March 2007) - Various memory leaks plugged and NULL pointer fixes made in the ssh code. Daniel (15 March 2007) - Nick made the curl tool accept globbing ranges that only is one number, i.e you can now use [1-1] without curl complaining. Daniel (10 March 2007) - Eygene Ryabinkin: The problem is the following: when we're calling Curl_done and it decides to keep the connection opened ('left intact'), then the caller is not notified that the connection was done via the NULLifying of the pointer, so some easy handle is keeping the pointer to this connection. Later ConnectionExists can select such connection for reuse even if we're not pipelining: pipeLen is zero, so the (pipeLen > 0 && !canPipeline) is false and we can reuse this connection for another easy handle. But thus the connection will be shared between two easy handles if the handle that wants to take the ownership is not the same as was not notified of the connection was done in Curl_done. And when some of these easy handles will get their connection really freed the another one will still keep the pointer. My fix was rather trivial: I just added the NULLification to the 'else' branch in the Curl_done. My tests with Git and ElectricFence showed no problems both for HTTP pulling and cloning. Repository size is about 250 Mb, so it was a considerable amount of Curl's work. Dan F (9 March 2007) - Updated the test harness to add a new "crypto" feature check and updated the appropriate test case to use it. For now, this is treated the same as the "SSL" feature because curl doesn't list it separately. Daniel (9 March 2007) - Robert Iakobashvili fixed CURLOPT_INTERFACE for IPv6. - Robert A. Monat improved the maketgz and VC6/8 generating to set the correct machine type too. - Justin Fletcher fixed a file descriptor leak in the curl tool when trying to upload a file it couldn't open. Bug #1676581 (http://curl.haxx.se/bug/view.cgi?id=1676581) Dan F (9 March 2007) - Updated the test harness to check for protocol support before running each test, fixing KNOWN_BUGS #11. Dan F (7 March 2007) - Reintroduced (after a 3 year hiatus) an FTPS test case (400) into the test harness. It is very limited as it supports only ftps:// URLs with --ftp-ssl-control specified, which implicitly encrypts the control channel but not the data channels. That allows stunnel to be used with an unmodified ftp server in exactly the same way that the test https server is set up. Dan F (7 March 2007) - Honour --ftp-ssl-control on ftps:// URLs to allow encrypted control and unencrypted data connections. Dan F (6 March 2007) - Fixed a couple of improper pointer uses detected by valgrind in test cases 181 & 216. Daniel (2 March 2007) - Robert A. Monat and Shmulik Regev helped out to fix the new */Makefile.vc8 makefiles that are included in the source release archives, generated from the Makefile.vc6 files by the maketgz script. I also modified the root Makefile to have a VC variable that defaults to vc6 but can be overridden to allow it to be used for vc8 as well. Like this: nmake VC=vc8 vc Daniel (27 February 2007) - Hang Kin Lau found and fixed: When I use libcurl to connect to an https server through a proxy and have the remote https server port set using the CURLOPT_PORT option, protocol gets reset to http from https after the first request. User defined URL was modified internally by libcurl and subsequent reuse of the easy handle may lead to connection using a different protocol (if not originally http). I found that libcurl hardcoded the protocol to "http" when it tries to regenerate the URL if CURLOPT_PORT is set. I tried to fix the problem as follows and it's working fine so far Daniel (25 February 2007) - Adam D. Moss made the HTTP CONNECT procedure less blocking when used from the multi interface. Note that it still does a part of the connection in a blocking manner. Daniel (23 February 2007) - Added warning outputs if the command line uses more than one of the options -v, --trace and --trace-ascii, since it could really confuse the user. Clarified this fact in the man page. Daniel (21 February 2007) - Ravi Pratap provided work on libcurl making pipelining more robust and fixing some bugs: o Don't mix GET and POST requests in a pipeline o Fix the order in which requests are dispatched from the pipeline o Fixed several curl bugs with pipelining when the server is returning chunked encoding: * Added states to chunked parsing for final CRLF * Rewind buffer after parsing chunk with data remaining * Moved chunked header initializing to a spot just before receiving headers Daniel (20 February 2007) - Linus Nielsen Feltzing changed the CURLOPT_FTP_SSL_CCC option to handle active and passive CCC shutdown and added the --ftp-ssl-ccc-mode command line option. Daniel (19 February 2007) - Ian Turner fixed the libcurl.m4 macro's support for --with-libcurl. - Shmulik Regev found a memory leak in re-used HTTPS connections, at least when the multi interface was used. - Robson Braga Araujo made passive FTP transfers work with SOCKS (both 4 and 5). Daniel (18 February 2007) - Jeff Pohlmeyer identified two problems: first a rather obscure problem with the multi interface and connection re-use that could make a curl_multi_remove_handle() ruin a pointer in another handle. The second problem was less of an actual problem but more of minor quirk: the re-using of connections wasn't properly checking if the connection was marked for closure. Daniel (16 February 2007) - Duncan Mac-Vicar Prett and Michal Marek reported problems with resetting CURLOPT_RANGE back to no range on an easy handle when using FTP. Dan F (14 February 2007) - Fixed curl-config --libs so it doesn't list unnecessary libraries (and therefore introduce unnecessary dependencies) when it's not needed. Also, don't bother adding a library path of /usr/lib Daniel (13 February 2007) - The default password for anonymous FTP connections is now changed to be "ftp@example.com". - Robert A. Monat made libcurl build fine with VC2005 - it doesn't have gmtime_r() like the older VC versions. He also made use of some machine- specific defines to differentiate the "OS" define. Daniel (12 February 2007) - Rob Crittenden added support for NSS (Network Security Service) for the SSL/TLS layer. http://www.mozilla.org/projects/security/pki/nss/ This is the fourth supported library for TLS/SSL that libcurl supports! - Shmulik Regev fixed so that the final CRLF of HTTP response headers are sent to the debug callback. - Shmulik Regev added CURLOPT_HTTP_CONTENT_DECODING and CURLOPT_HTTP_TRANSFER_DECODING that if set to zero will disable libcurl's internal decoding of content or transfer encoded content. This may be preferable in cases where you use libcurl for proxy purposes or similar. The command line tool got a --raw option to disable both at once. - release tarballs made with maketgz will from now on have a LIBCURL_TIMESTAMP define set to hold the exact date and time of when the tarball was built, as a human readable string using the UTC time zone. - Jeff Pohlmeyer fixed a flaw in curl_multi_add_handle() when adding a handle that has an easy handle present in the "closure" list pending closure. Daniel (6 February 2007) - Regular file downloads wiht SFTP and SCP are now done using the non-blocking API of libssh2, if the libssh2 headers seem to support them. This will make SCP and SFTP much more responsive and better libcurl citizens when used with the multi interface etc. Daniel (5 February 2007) - Michael Wallner added support for CURLOPT_TIMEOUT_MS and CURLOPT_CONNECTTIMEOUT_MS that, as their names suggest, do the timeouts with millisecond resolution. The only restriction to that is the alarm() (sometimes) used to abort name resolves as that uses full seconds. I fixed the FTP response timeout part of the patch. Internally we now count and keep the timeouts in milliseconds but it also means we multiply set timeouts with 1000. The effect of this is that no timeout can be set to more than 2^31 milliseconds (on 32 bit systems), which equals 24.86 days. We probably couldn't before either since the code did *1000 on the timeout values on several places already. Daniel (3 February 2007) - Yang Tse fixed the cookie expiry date in several test cases that started to fail since they used "1 feb 2007"... - Manfred Schwarb reported that socks5 support was broken and help us pinpoint the problem. The code now tries harder to use httproxy and proxy where apppropriate, as not all proxies are HTTP... Version 7.16.1 (29 January 2007) Daniel (29 January 2007) - Michael Wallner reported that when doing a CONNECT with a custom User-Agent header, you got _two_ User-Agent headers in the CONNECT request...! Added test case 287 to verify the fix. Daniel (28 January 2007) - curl_easy_reset() now resets the CA bundle path correctly. - David McCreedy fixed the Curl command line tool for HTTP on non-ASCII platforms. Daniel (25 January 2007) - Added the --libcurl [file] option to curl. Append this option to any ordinary curl command line, and you will get a libcurl-using source code written to the file that does the equivalent operation of what your command line operation does! Dan F (24 January 2007) - Fixed a dangling pointer problem that prevented the http_proxy environment variable from being properly used in many cases (and caused test case 63 to fail). Daniel (23 January 2007) - David McCreedy did NTLM changes mainly for non-ASCII platforms: #1 There's a compilation error in http_ntlm.c if USE_NTLM2SESSION is NOT defined. I noticed this while testing various configurations. Line 867 of the current http_ntlm.c is a closing bracket for an if/else pair that only gets compiled in if USE_NTLM2SESSION is defined. But this closing bracket wasn't in an #ifdef so the code fails to compile unless USE_NTLM2SESSION was defined. Lines 198 and 140 of my patch wraps that closing bracket in an #ifdef USE_NTLM2SESSION. #2 I noticed several picky compiler warnings when DEBUG_ME is defined. I've fixed them with casting. By the way, DEBUG_ME was a huge help in understanding this code. #3 Hopefully the last non-ASCII conversion patch for libcurl in a while. I changed the "NTLMSSP" literal to hex since this signature must always be in ASCII. Conversion code was strategically added where necessary. And the Curl_base64_encode calls were changed so the binary "blobs" http_ntlm.c creates are NOT translated on non-ASCII platforms. Dan F (22 January 2007) - Converted (most of) the test data files into genuine XML. A handful still are not, due mainly to the lack of support for XML character entities (e.g. & => & ). This will make it easier to validate test files using tools like xmllint, as well as to edit and view them using XML tools. Daniel (16 January 2007) - Armel Asselin improved libcurl to behave a lot better when an easy handle doing an FTP transfer is removed from a multi handle before completion. The fix also fixed the "alive counter" to be correct on "premature removal" for all protocols. Dan F (16 January 2007) - Fixed a small memory leak in tftp uploads discovered by curl's memory leak detector. Also changed tftp downloads to URL-unescape the downloaded file name. Daniel (14 January 2007) - David McCreedy provided libcurl changes for doing HTTP communication on non-ASCII platforms. It does add some complexity, most notably with more #ifdefs, but I want to see this supported added and I can't see how we can add it without the extra stuff added. - Setting CURLOPT_COOKIELIST to "ALL" when no cookies at all was present, libcurl would crash when trying to read a NULL pointer. Daniel (12 January 2007) - Toby Peterson found a nasty bug that prevented (lib)curl from properly downloading (most) things that were larger than 4GB on 32 bit systems. Matt Witherspoon helped as narrow down the problem. Daniel (5 January 2007) - Linus Nielsen Feltzing introduced the --ftp-ssl-ccc command line option to curl that uses the new CURLOPT_FTP_SSL_CCC option in libcurl. If enabled, it will make libcurl shutdown SSL/TLS after the authentication is done on a FTP-SSL operation. Daniel (4 January 2007) - David McCreedy made changes to allow base64 encoding/decoding to work on non-ASCII platforms. Daniel (3 January 2007) - Matt Witherspoon fixed the flaw which made libcurl 7.16.0 always store downloaded data in two buffers, just to be able to deal with a special HTTP pipelining case. That is now only activated for pipelined transfers. In Matt's case, it showed as a considerable performance difference, Daniel (2 January 2007) - Victor Snezhko helped us fix bug report #1603712 (http://curl.haxx.se/bug/view.cgi?id=1603712) (known bug #36) --limit-rate (CURLOPT_MAX_SEND_SPEED_LARGE and CURLOPT_MAX_RECV_SPEED_LARGE) are broken on Windows (since 7.16.0, but that's when they were introduced as previous to that the limiting logic was made in the application only and not in the library). It was actually also broken on select()-based systems (as apposed to poll()) but we haven't had any such reports. We now use select(), Sleep() or delay() properly to sleep a while without waiting for anything input or output when the rate limiting is activated with the easy interface. - Modified libcurl.pc.in to use Libs.private for the libs libcurl itself needs to get built static. It has been mentioned before and was again brought to our attention by Nathanael Nerode who filed debian bug report #405226 (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=405226).
