2017-05-03lib: fix compiler warningsMarcel Raad
Fix the following warnings when building the tests by using the correct types: cast from 'const char *' to 'void *' drops const qualifier [-Wcast-qual] implicit conversion changes signedness [-Wsign-conversion]
2017-04-26lib: remove unused codeMarcel Raad
This fixes the following clang warnings: macro is not used [-Wunused-macros] will never be executed [-Wunreachable-code] Closes https://github.com/curl/curl/pull/1448
2017-03-13Improve code readbilitySylvestre Ledru
... by removing the else branch after a return, break or continue. Closes #1310
2016-12-21lib: fix MSVC compiler warningsMarcel Raad
Visual C++ complained: warning C4267: '=': conversion from 'size_t' to 'long', possible loss of data warning C4701: potentially uninitialized local variable 'path' used
2016-12-19printf: fix floating point buffer overflow issuesDaniel Stenberg
... and add a bunch of floating point printf tests
2016-12-13checksrc: stricter no-space-before-paren enforcementDaniel Stenberg
In order to make the code style more uniform everywhere
2016-11-08printf: fix ".*f" handlingDaniel Stenberg
It would always use precision 1 instead of reading it from the argument list as intended. Reported-by: Ray Satiro Bug: #1113
2016-10-31aprintf: detect wrap-around when growing allocationDaniel Stenberg
On 32bit systems we could otherwise wrap around after 2GB and allocate 0 bytes and crash. CVE-2016-8618 Bug: https://curl.haxx.se/docs/adv_20161102D.html Reported-by: Cure53
2016-10-08mprintf: return error on too many argumentsDaniel Stenberg
128 arguments should be enough for everyone
2016-05-17dprintf_formatf: fix (false?) Coverity warningDaniel Stenberg
CID 1024412: Memory - illegal accesses (OVERRUN). Claimed to happen when we run over 'workend' but the condition says <= workend and for all I can see it should be safe. Compensating for the warning by adding a byte margin in the buffer. Also, removed the extra brace level indentation in the code and made it so that 'workend' is only assigned once within the function.
2016-05-13mprintf: Fix processing of width and prec argsJay Satiro
Prior to this change a width arg could be erroneously output, and also width and precision args could not be used together without crashing. "%0*d%s", 2, 9, "foo" Before: "092" After: "09foo" "%*.*s", 5, 2, "foo" Before: crash After: " fo" Test 557 is updated to verify this and more
2016-04-01curl/mprintf.h: remove support for _MPRINTF_REPLACEDaniel Stenberg
The define is not in our name space and is therefore not protected by our API promises. It was only really used by libcurl internals but was mostly erased from there already in 8aabbf5 (March 2015). This is supposedly the final death blow to that define from everywhere. As a side-effect, making sure _MPRINTF_REPLACE is gone and not used, I made the lib tests in tests/libtest/ use curl_printf.h for its redefine magic and then subsequently the use of sprintf() got banned in the tests as well (as it is in libcurl internals) and I then replaced them all with snprintf(). In the unlikely event that any users is actually using this define and gets sad by this change, it is very easily copied to the user's own code.

2014-05-04mprintf: allow %.s with data not being zero terminatedDaniel Stenberg
If the precision is indeed shorter than the string, don't strlen() to find the end because that's not how the precision operator works. I also added a unit test for curl_msnprintf to make sure this works and that the fix doesn't a few other basic use cases. I found a POSIX compliance problem that I marked TODO in the unit test, and I figure we need to add more tests in the future. Reported-by: Török Edwin
2013-12-30mprintf: Added support for I, I32 and I64 size specifiersSteve Holme
Added support to the built-in printf() replacement functions, for these non-ANSI extensions when compiling under Visual Studio, Borland, Watcom and MinGW. This fixes problems when generating libcurl source code that contains curl_off_t variables.
2013-06-25printf: make sure %x are treated unsignedDaniel Stenberg
When using %x, the number must be treated as unsigned as otherwise it would get sign-extended on for example 64bit machines and do wrong output. This problem showed when doing printf("%08x", 0xffeeddcc) on a 64bit host.
2013-03-07checksrc: ban unsafe functionsDaniel Stenberg
The list of unsafe functions currently consists of sprintf, vsprintf, strcat, strncat and gets. Subsequently, some existing code needed updating to avoid warnings on this.
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.

2011-09-02MemoryTracking: fix logging of free() calls done where Curl_safefree is calledYang Tse
Just internal stuff... Curl_safefree is now a macro defined in memdebug.h instead of a function prototyped in url.h and implemented in url.c, so inclusion of url.h is no longer required in order to simply use Curl_safefree. Provide definition of macro WHILE_FALSE in setup_once.h in order to allow other macros such as DEBUGF and DEBUGASSERT, and code using it, to compile without 'conditional expression is constant' warnings. The WHILE_FALSE stuff fixes 150+ MSVC compiler warnings.
