2018-08-13mingw: enable atomic O_APPENDLibravatar Johannes Sixt1-2/+39
The Windows CRT implements O_APPEND "manually": on write() calls, the file pointer is set to EOF before the data is written. Clearly, this is not atomic. And in fact, this is the root cause of failures observed in t5552-skipping-fetch-negotiator.sh and t5503-tagfollow.sh, where different processes write to the same trace file simultanously; it also occurred in t5400-send-pack.sh, but there it was worked around in 71406ed4d6 ("t5400: avoid concurrent writes into a trace file", 2017-05-18). Fortunately, Windows does support atomic O_APPEND semantics using the file access mode FILE_APPEND_DATA. Provide an implementation that does. This implementation is minimal in such a way that it only implements the open modes that are actually used in the Git code base. Emulation for other modes can be added as necessary later. To become aware of the necessity early, the unusal error ENOSYS is reported if an unsupported mode is encountered.

2018-03-19mingw: abort on invalid strftime formatsLibravatar Johannes Schindelin2-0/+14
On Windows, strftime() does not silently ignore invalid formats, but warns about them and then returns 0 and sets errno to EINVAL. Unfortunately, Git does not expect such a behavior, as it disagrees with strftime()'s semantics on Linux. As a consequence, Git misinterprets the return value 0 as "I need more space" and grows the buffer. As the larger buffer does not fix the format, the buffer grows and grows and grows until we are out of memory and abort. Ideally, we would switch off the parameter validation just for strftime(), but we cannot even override the invalid parameter handler via _set_thread_local_invalid_parameter_handler() using MINGW because that function is not declared. Even _set_invalid_parameter_handler(), which *is* declared, does not help, as it simply does... nothing. So let's just bite the bullet and override strftime() for MINGW and abort on an invalid format string. While this does not provide the best user experience, it is the best we can do. See https://msdn.microsoft.com/en-us/library/fe06s4ak.aspx for more details.

2017-11-02mingw: optionally redirect stderr/stdout via the same handleLibravatar Johannes Schindelin1-0/+15
The "2>&1" notation in Powershell and in Unix shells implies that stderr is redirected to the same handle into which stdout is already written. Let's use this special value to allow the same trick with GIT_REDIRECT_STDERR and GIT_REDIRECT_STDOUT: if the former's value is `2>&1`, then stderr will simply be written to the same handle as stdout.

2017-11-02mingw: add experimental feature to redirect standard handlesLibravatar Johannes Schindelin1-0/+43
Particularly when calling Git from applications, such as Visual Studio's Team Explorer, it is important that stdin/stdout/stderr are closed properly. However, when spawning processes on Windows, those handles must be marked as inheritable if we want to use them, but that flag is a global flag and may very well be used by other spawned processes which then do not know to close those handles. Let's introduce a set of environment variables (GIT_REDIRECT_STDIN and friends) that specify paths to files, or even better, named pipes (which are similar to Unix sockets) and that are used by the spawned Git process. This helps work around above-mentioned issue: those named pipes will be opened in a non-inheritable way upon startup, and no handles are passed around (and therefore no inherited handles need to be closed by any spawned child). This feature shipped with Git for Windows (marked as experimental) since v2.11.0(2), so it has seen some serious testing in the meantime.

2017-10-10cleanup: fix possible overflow errors in binary searchLibravatar Derrick Stolee2-3/+3
A common mistake when writing binary search is to allow possible integer overflow by using the simple average: mid = (min + max) / 2; Instead, use the overflow-safe version: mid = min + (max - min) / 2; This translation is safe since the operation occurs inside a loop conditioned on "min < max". The included changes were found using the following git grep: git grep '/ *2;' '*.c' Making this cleanup will prevent future review friction when a new binary search is contructed based on existing code.

Dynamic loading of DLL functions is duplicated in several places in Git for Windows' source code.

The return value of the INIT_PROC_ADDR() call has to be checked; If it is NULL, the function was not found in the specified DLL. Example: DECLARE_PROC_ADDR(kernel32.dll, BOOL, CreateHardLinkW, LPCWSTR, LPCWSTR, LPSECURITY_ATTRIBUTES); if (!INIT_PROC_ADDR(CreateHardLinkW)) return error("Could not find CreateHardLinkW() function"; if (!CreateHardLinkW(source, target, NULL)) return error("could not create hardlink from %S to %S", source, target); return 0; Signed-off-by: Karsten Blees <blees@dcon.de> Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Reviewed-by: Jonathan Nieder <jrnieder@gmail.com> Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

If git is built with the FREAD_READS_DIRECTORIES build variable set, this would cause sparse to issue a 'not declared, should it be static?' warning on Linux. This is a result of the method employed by 'compat/fopen.c' to suppress the (possible) redefinition of the (system) fopen macro, which also removes the extern declaration of the git_fopen function. In order to suppress the warning, introduce a new macro to suppress the definition (or possibly the re-definition) of the fopen symbol as a macro override. This new macro (SUPPRESS_FOPEN_REDEFINITION) is only defined in 'compat/fopen.c', just prior to the inclusion of the 'git-compat-util.h' header file.

2017-05-23mingw: simplify PATH handlingLibravatar René Scharfe1-68/+23

Change lookup_prog() to take the directory name as a length-limited string instead of as a NUL-terminated one and parse PATH directly in path_lookup().

2017-05-08winansi: avoid use of uninitialized valueLibravatar Johannes Schindelin1-0/+7
To initialize the foreground color attributes of "plain text", our ANSI emulation tries to infer them from the currently attached console while running the is_console() function. This function first tries to detect any console attached to stdout, then it is called with stderr. If neither stdout nor stderr has any console attached, it does not actually matter what we use for "plain text" attributes, as we never need to output any text to any console in that case. However, after working on stdout and stderr, is_console() is called with stdin, and it still tries to initialize the "plain text" attributes if they had not been initialized earlier. In this case, we cannot detect any attributes, and we used an uninitialized value for them. Naturally, Coverity complained about this use case because it could not reason about the code deeply enough to figure out that we do not even use those attributes in that case. Let's just initialize the value to 0 in that case, both to avoid future Coverity reports, and to help catch future regressions in case anybody changes the order of the is_console() calls (which would make the text black on black).
