2013-08-20curl_easy_perform_ev: debug/test functionDaniel Stenberg
This function is meant to work *exactly* as curl_easy_perform() but will use the event-based libcurl API internally instead of curl_multi_perform(). To avoid relying on an actual event-based library and to not use non-portable functions (like epoll or similar), there's a rather inefficient emulation layer implemented on top of Curl_poll() instead. There's currently some convenience logging done in curl_easy_perform_ev which helps when tracking down problems. They may be suitable to remove or change once things seem to be fine enough. curl has a new --test-event option when built with debug enabled that then uses curl_easy_perform_ev() instead of curl_easy_perform(). If built without debug, using --test-event will only output a warning message. NOTE: curl_easy_perform_ev() is not part if the public API on purpose. It is only present in debug builds of libcurl and MUST NOT be considered stable even then. Use it for libcurl-testing purposes only. runtests.pl now features an -e command line option that makes it use --test-event for all curl command line tests. The man page is updated.
2013-08-12cleanup: removed one function, made one staticDaniel Stenberg
Moved Curl_easy_addmulti() from easy.c to multi.c, renamed it to easy_addmulti and made it static. Removed Curl_easy_initHandleData() and uses of it since it was emptied in commit cdda92ab67b47d74a.
2013-08-12SessionHandle: the protocol specific pointer is now a void *Daniel Stenberg
All protocol handler structs are now opaque (void *) in the SessionHandle struct and moved in the request-specific sub-struct 'SingleRequest'. The intension is to keep the protocol specific knowledge in their own dedicated source files [protocol].c etc. There's some "leakage" where this policy is violated, to be addressed at a later point in time.
2013-08-12urldata: clean up the use of the protocol specific structsDaniel Stenberg
1 - always allocate the struct in protocol->setup_connection. Some protocol handlers had to get this function added. 2 - always free at the end of a request. This is also an attempt to keep less memory in the handle after it is completed.

2013-07-29curl_easy_pause: on unpause, trigger mulit-socket handlingDaniel Stenberg
When the multi-socket API is used, we need the handle to be checked again when it gets unpaused. Bug: http://curl.haxx.se/mail/lib-2013-07/0239.html Reported-by: Justin Karneges

2013-07-19curl_easy_perform: gradually increase the delay timeDaniel Stenberg
Instead of going 50,100,150 etc millisecond delay time when nothing has been found to do or wait for, we now start lower and double each loop as in 4,8,16,32 etc. This lowers the minimum wait without sacrifizing the longer wait too much with unnecessary CPU cycles burnt.

2013-07-19WIN32 MemoryTracking: require UNICODE for wide strdup code supportYang Tse
2013-07-18Reinstate "WIN32 MemoryTracking: track wcsdup() _wcsdup() and _tcsdup() usage".Yang Tse
This reverts commit 7ed25cc, reinstating commit 8ec2cb5. As of 18-jul-2013 we still do have code in libcurl that makes use of these memory functions. Commit 8ec2cb5 comment still applies and is yet valid. These memory functions are solely used in Windows builds, so all related code is protected with '#ifdef WIN32' preprocessor conditional compilation directives. Specifically, wcsdup() _wcsdup() are used when building a Windows target with UNICODE and USE_WINDOWS_SSPI preprocessor symbols defined. This is the case when building a Windows UNICODE target with Windows native SSL/TLS support enabled. Realizing that wcsdup() _wcsdup() are used is a bit tricky given that usage of these is hidden behind _tcsdup() which is MS way of dealing with code that must tolerate UNICODE and non-UNICODE compilation. Additionally, MS header files and those compatible from other compilers use this preprocessor conditional compilation directive in order to select at compilation time whether 'wide' or 'ansi' MS API functions are used. Without this code, Windows build targets with Windows native SSL/TLS support enabled and MemoryTracking support enabled misbehave in tracking memory usage, regardless of being a UNICODE enabled build or not.

2013-06-25formpost: better random boundariesDaniel Stenberg
When doing multi-part formposts, libcurl used a pseudo-random value that was seeded with time(). This turns out to be bad for users who formpost data that is provided with users who then can guess how the boundary string will look like and then they can forge a different formpost part and trick the receiver. My advice to such implementors is (still even after this change) to not rely on the boundary strings being cryptographically strong. Fix your code and logic to not depend on them that much! I moved the Curl_rand() function into the sslgen.c source file now to be able to take advantage of the SSL library's random function if it provides one. If not, try to use the RANDOM_FILE for seeding and as a last resort keep the old logic, just modified to also add microseconds which makes it harder to properly guess the exact seed. The formboundary() function in formdata.c is now using 64 bit entropy for the boundary and therefore the string of dashes was reduced by 4 letters and there are 16 hex digits following it. The total length is thus still the same. Bug: http://curl.haxx.se/bug/view.cgi?id=1251 Reported-by: "Floris"
2013-06-24SIGPIPE: don't use 'data' in sigpipe restoreDaniel Stenberg
Follow-up fix from 7d80ed64e43515. The SessionHandle may not be around to use when we restore the sigpipe sighandler so we store the no_signal boolean in the local struct to know if/how to restore.
2013-06-22SIGPIPE: ignored while inside the libraryDaniel Stenberg
... and restore the ordinary handling again when it returns. This is done for curl_easy_perform() and curl_easy_cleanup() only for now - and only when built to use OpenSSL as backend as this is the known culprit for the spurious SIGPIPEs people have received.

2013-06-13curl_easy_perform: avoid busy-loopingDaniel Stenberg
When curl_multi_wait() finds no file descriptor to wait for, it returns instantly and this must be handled gracefully within curl_easy_perform() or cause a busy-loop. Starting now, repeated fast returns without any file descriptors is detected and a gradually increasing sleep will be used (up to a max of 1000 milliseconds) before continuing the loop. Bug: http://curl.haxx.se/bug/view.cgi?id=1238 Reported-by: Miguel Angel
2013-05-12Revert "WIN32 MemoryTracking: track wcsdup() _wcsdup() and _tcsdup() usage"Daniel Stenberg
This reverts commit 8ec2cb5544b86306b702484ea785b6b9596562ab. We don't have any code anywhere in libcurl (or the curl tool) that use wcsdup so there's no such memory use to track. It seems to cause mild problems with the Borland compiler though that we may avoid by reverting this change again. Bug: http://curl.haxx.se/mail/lib-2013-05/0070.html
2013-04-26curl_easy_init: use less mallocsDaniel Stenberg
By introducing an internal alternative to curl_multi_init() that accepts parameters to set the hash sizes, easy handles will now use tiny socket and connection hash tables since it will only ever add a single easy handle to that multi handle. This decreased the number mallocs in test 40 (which is a rather simple and typical easy interface use case) from 1142 to 138. The maximum amount of memory allocated used went down from 118969 to 78805.

2013-03-25WIN32 MemoryTracking: track wcsdup() _wcsdup() and _tcsdup() usageYang Tse
As of 25-mar-2013 wcsdup() _wcsdup() and _tcsdup() are only used in WIN32 specific code, so tracking of these has not been extended for other build targets. Without this fix, memory tracking system on WIN32 builds, when using these functions, would provide misleading results. In order to properly extend this support for all targets curl.h would have to define curl_wcsdup_callback prototype and consequently wchar_t should be visible before that in curl.h. IOW curl_wchar_t defined in curlbuild.h and this pulling whatever system header is required to get wchar_t definition. Additionally a new curl_global_init_mem() function that also receives user defined wcsdup() callback would be required.

2013-01-09build: fix circular header inclusion with other packagesYang Tse
This commit renames lib/setup.h to lib/curl_setup.h and renames lib/setup_once.h to lib/curl_setup_once.h. Removes the need and usage of a header inclusion guard foreign to libcurl. [1] Removes the need and presence of an alarming notice we carried in old setup_once.h [2] ---------------------------------------- 1 - lib/setup_once.h used __SETUP_ONCE_H macro as header inclusion guard up to commit ec691ca3 which changed this to HEADER_CURL_SETUP_ONCE_H, this single inclusion guard is enough to ensure that inclusion of lib/setup_once.h done from lib/setup.h is only done once. Additionally lib/setup.h has always used __SETUP_ONCE_H macro to protect inclusion of setup_once.h even after commit ec691ca3, this was to avoid a circular header inclusion triggered when building a c-ares enabled version with c-ares sources available which also has a setup_once.h header. Commit ec691ca3 exposes the real nature of __SETUP_ONCE_H usage in lib/setup.h, it is a header inclusion guard foreign to libcurl belonging to c-ares's setup_once.h The renaming this commit does, fixes the circular header inclusion, and as such removes the need and usage of a header inclusion guard foreign to libcurl. Macro __SETUP_ONCE_H no longer used in libcurl. 2 - Due to the circular interdependency of old lib/setup_once.h and the c-ares setup_once.h header, old file lib/setup_once.h has carried back from 2006 up to now days an alarming and prominent notice about the need of keeping libcurl's and c-ares's setup_once.h in sync. Given that this commit fixes the circular interdependency, the need and presence of mentioned notice is removed. All mentioned interdependencies come back from now old days when the c-ares project lived inside a curl subdirectory. This commit removes last traces of such fact.

2012-12-07Introducing a new persistent connection caching system using "bundles".Linus Nielsen Feltzing
A bundle is a list of all persistent connections to the same host. The connection cache consists of a hash of bundles, with the hostname as the key. The benefits may not be obvious, but they are two: 1) Faster search for connections to reuse, since the hash lookup only finds connections to the host in question. 2) It lays out the groundworks for an upcoming patch, which will introduce multiple HTTP pipelines. This patch also removes the awkward list of "closure handles", which were needed to send QUIT commands to the FTP server when closing a connection. Now we allocate a separate closure handle and use that one to close all connections. This has been tested in a live system for a few weeks, and of course passes the test suite.
