2019-04-22memdebug: fix variable nameGisle Vanem
Follow-up to 76b6348 which renamed logfile as curl_dbg_logfile. Ref: https://github.com/curl/curl/commit/76b6348#r33259088
2019-03-12memdebug: log pointer before freeing its dataDaniel Stenberg
Coverity warned for two potentional "Use after free" cases. Both are false positives because the memory wasn't used, it was only the actual pointer value that was logged. The fix still changes the order of execution to avoid the warnings. Coverity CID 1443033 and 1443034 Closes #3671
2019-03-08memdebug: make debug-specific functions use curl_dbg_ prefixDaniel Stenberg
To not "collide" or use up the regular curl_ name space. Also makes them easier to detect in helper scripts. Closes #3656
2019-02-14memdebug: bring back curl_mark_scloseDaniel Stenberg
Used by debug builds with NSS. Reverted from 05b100aee247bb
2019-02-10cleanup: make local functions staticDaniel Stenberg
urlapi: turn three local-only functions into statics conncache: make conncache_find_first_connection static multi: make detach_connnection static connect: make getaddressinfo static curl_ntlm_core: make hmac_md5 static http2: make two functions static http: make http_setup_conn static connect: make tcpnodelay static tests: make UNITTEST a thing to mark functions with, so they can be static for normal builds and non-static for unit test builds ... and mark Curl_shuffle_addr accordingly. url: make up_free static setopt: make vsetopt static curl_endian: make write32_le static rtsp: make rtsp_connisdead static warnless: remove unused functions memdebug: remove one unused function, made another static
2018-11-23snprintf: renamed and we now only use msnprintf()Daniel Stenberg
The function does not return the same value as snprintf() normally does, so readers may be mislead into thinking the code works differently than it actually does. A different function name makes this easier to detect. Reported-by: Tomas Hoger Assisted-by: Daniel Gustafsson Fixes #3296 Closes #3297

2016-05-30memdebug: fix MSVC crash with -DMEMDEBUG_LOG_SYNCGisle Vanem
Fixes #828
2016-04-29lib: include curl_printf.h as one of the last headersDaniel Stenberg
curl_printf.h defines printf to curl_mprintf, etc. This can cause problems with external headers which may use __attribute__((format(printf, ...))) markers etc. To avoid that they cause problems with system includes, we include curl_printf.h after any system headers. That makes the three last headers to always be, and we keep them in this order: curl_printf.h curl_memory.h memdebug.h None of them include system headers, they all do funny #defines. Reported-by: David Benjamin Fixes #743
2016-03-14memdebug: skip logging the limit countdown, fflush when reachedDaniel Stenberg
2016-02-03URLs: change all http:// URLs to https://Daniel Stenberg
2015-06-01curl_setup: Add macros for FOPEN_READTEXT, FOPEN_WRITETEXTJay Satiro
- Change fopen calls to use FOPEN_READTEXT instead of "r" or "rt" - Change fopen calls to use FOPEN_WRITETEXT instead of "w" or "wt" This change is to explicitly specify when we need to read/write text. Unfortunately 't' is not part of POSIX fopen so we can't specify it directly. Instead we now have FOPEN_READTEXT, FOPEN_WRITETEXT. Prior to this change we had an issue on Windows if an application that uses libcurl overrides the default file mode to binary. The default file mode in Windows is normally text mode (translation mode) and that's what libcurl expects.

2015-03-17checksrc: detect and remove space before trailing semicolonsDaniel Stenberg
2015-03-03mprintf.h: remove #ifdef CURLDEBUGDaniel Stenberg
... and as a consequence, introduce curl_printf.h with that re-define magic instead and make all libcurl code use that instead.
2013-12-25curl_dofree: allow free(NULL)Daniel Stenberg
Previously this memdebug free() replacement didn't properly work with a NULL argument which has made us write code that avoids calling free(NULL) - which causes some extra nuisance and unnecessary code. Starting now, we should allow free(NULL) even when built with the memdebug system enabled. free(NULL) is permitted by POSIX

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.
2013-05-12Revert "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
2013-03-25WIN32 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.

2011-08-17MemoryTracking: adjust curl_domalloc() and curl_dofree() memory fillingYang Tse
Until 2011-08-17 libcurl's Memory Tracking feature also performed automatic malloc and free filling operations using 0xA5 and 0x13 values. Our own preinitialization of dynamically allocated memory might be useful when not using third party memory debuggers, but on the other hand this would fool memory debuggers into thinking that all dynamically allocated memory is properly initialized. As a default setting, libcurl's Memory Tracking feature no longer performs preinitialization of dynamically allocated memory on its own. If you know what you are doing, and really want to retain old behavior, you can achieve this compiling with preprocessor symbols CURL_MT_MALLOC_FILL and CURL_MT_FREE_FILL defined with appropriate values.
