00c66dfd	2019-01-10T22:43:59	errors: update static analysis tools for giterr Update GITERR and giterr usages in the static code analysis tools to use the new names.
859ed5dd	2016-02-23T09:54:26	common: introduce GITERR_CHECK_ALLOC_BUF We commonly have to check if a git_buf has been allocated correctly or if we ran out of memory. Introduce a new macro similar to `GITERR_CHECK_ALLOC` which checks if we ran OOM and if so returns an error. Provide a `#nodef` for Coverity to mark the error case as an abort path.
f2a554b4	2016-02-22T14:43:28	coverity: hint git_vector_foreach does not deref NULL contents Coverity does not comprehend the connection between a vector's size and the contents pointer, that is that the vector's pointer is non-NULL when its size is positive. As the vector code should be reasonably well tested and users are expected to not manually modify a vector's contents it seems save to assume that the macros will never dereference a NULL pointer. Fix Coverity warnings by overriding the foreach macros with macros that explicitly aborting when (v)->contents is NULL.
40f6f225	2016-02-15T10:58:52	coverity: hint that string length is at least 2 When checking if a string is prefixed by a drive letter (e.g. "C:") we verify this by inspecting the first and second character of the string. Coverity thinks this is a defect as we do not check the string's length first, but in fact we only check the second character if the first character is part of the alphabet, that is it cannot be '\0'. Fix this by overriding the macro and explicitly checking the string's length.

8dddea42	2016-02-10T10:59:14	coverity: provide nodef for GITERR_CHECK_ALLOC Coverity currently lists a lot of errors with regard to GITERR_CHECK_ALLOC causing resource leaks. We know this macro is only invoked when we want to abort because we are out of memory. Coverity allows for overriding the default model where we know that certain functions guarantee a desired behavior. The user_nodefs.h is used to override the behavior of macros. Re-define GITERR_CHECK_ALLOC inside of it to specify its abort nature.
