Various compilation fixes and squelching of warnings. * js/misc-fixes: Correct fscanf formatting string for I64u values Silence GCC's "cast of pointer to integer of a different size" warning Squelch warning about an integer overflow
2015-10-26Silence GCC's "cast of pointer to integer of a different size" warningLibravatar Johannes Schindelin1-2/+4
When calculating hashes from pointers, it actually makes sense to cut off the most significant bits. In that case, said warning does not make a whole lot of sense. So let's just work around it by casting the pointer first to intptr_t and then casting up/down to the final integral type.

2015-10-23compat/mingw.c: remove printf format warningLibravatar Johannes Sixt1-1/+1
5096d490 (convert trivial sprintf / strcpy calls to xsnprintf) converted two sprintf calls. Now GCC warns that "format '%u' expects argument of type 'unsigned int', but argument 4 has type 'long unsigned int'". Instead of changing the format string, use a variable of type unsigned in place of the typedef-ed type DWORD, which hides that it is actually an unsigned long. There is no correctness issue with the old code because unsigned long and unsigned are always of the same size on Windows, even in 64-bit builds.

2015-10-05prefer memcpy to strcpyLibravatar Jeff King1-2/+3
When we already know the length of a string (e.g., because we just malloc'd to fit it), it's nicer to use memcpy than strcpy, as it makes it more obvious that we are not going to overflow the buffer (because the size we pass matches the size in the allocation). This also eliminates calls to strcpy, which make auditing the code base harder. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2015-10-05probe_utf8_pathname_composition: use internal strbufLibravatar Jeff King2-9/+11
When we are initializing a .git directory, we may call probe_utf8_pathname_composition to detect utf8 mangling. We pass in a path buffer for it to use, and it blindly strcpy()s into it, not knowing whether the buffer is large enough to hold the result or not. In practice this isn't a big deal, because the buffer we pass in already contains "$GIT_DIR/config", and we append only a few extra bytes to it. But we can easily do the right thing just by calling git_path_buf ourselves. Technically this results in a different pathname (before we appended our utf8 characters to the "config" path, and now they get their own files in $GIT_DIR), but that should not matter for our purposes.

2015-09-25compat/hstrerror: convert sprintf to snprintfLibravatar Jeff King1-1/+1
This is a trivially correct use of sprintf, as our error number should not be excessively long. But it's still nice to drop an sprintf call.

2015-09-25convert trivial sprintf / strcpy calls to xsnprintfLibravatar Jeff King2-4/+6
We sometimes sprintf into fixed-size buffers when we know that the buffer is large enough to fit the input (either because it's a constant, or because it's numeric input that is bounded in size). Likewise with strcpy of constant strings. However, these sites make it hard to audit sprintf and strcpy calls for buffer overflows, as a reader has to cross-reference the size of the array with the input. Let's use xsnprintf instead, which communicates to a reader that we don't expect this to overflow (and catches the mistake in case we do).

2015-09-25compat/inet_ntop: fix off-by-one in inet_ntop4Libravatar Jeff King1-3/+3
Our compat inet_ntop4 function writes to a temporary buffer with snprintf, and then uses strcpy to put the result into the final "dst" buffer. We check the return value of snprintf against the size of "dst", but fail to account for the NUL terminator. As a result, we may overflow "dst" with a single NUL. In practice, this doesn't happen because the output of inet_ntop is limited, and we provide buffers that are way oversized. We can fix the off-by-one check easily, but while we are here let's also use strlcpy for increased safety, just in case there are other bugs lurking. As a side note, this compat code seems to be BSD-derived. Searching for "vixie inet_ntop" turns up NetBSD's latest version of the same code, which has an identical fix (and switches to strlcpy, too!).

2015-09-14poll: honor the timeout on Win32Libravatar Edward Thomson1-2/+14
Ensure that when passing a pipe, the gnulib poll replacement will not return 0 before the timeout has passed. Not obeying the timeout (and merely returning 0) causes pathological behavior when preparing a packfile for a repository and taking a long time to do so. If poll were to return 0 immediately, this would cause keep-alives to get sent as quickly as possible until the packfile was created. Such deviance from the standard would cause megabytes (or more) of keep-alive packets to be sent. GetTickCount is used as it is efficient, stable and monotonically increasing. (Neither GetSystemTime nor QueryPerformanceCounter have all three of these properties.)

This adds simple wrapper functions around calls to stat(), fstat(), and lstat() that translate the operating system's native file type bits to those used by most operating systems. It also rewrites the S_IF* macros to the common values, so all file type processing is performed using the translated modes. This makes projects portable across operating systems that use different file type definitions. Only the file type bits may be affected by these compatibility functions; the file permission bits are assumed to be 07777 and are passed through unchanged.

Our emulation in mingw_open() does not get this right: it checks only for O_CREAT. Fix it to check for a write request.

2014-07-21Win32: keep the environment sortedLibravatar Karsten Blees1-39/+65
The Windows environment is sorted, keep it that way for O(log n) environment access. Change compareenv to compare only the keys, so that it can be used to find an entry irrespective of the value. Change lookupenv to binary seach for an entry. Return one's complement of the insert position if not found (libc's bsearch returns NULL). Replace MSVCRT's getenv with a minimal do_getenv based on the binary search function. Change do_putenv to insert new entries at the correct position. Simplify the function by swapping if conditions and using memmove instead of for loops. Move qsort from make_environment_block to mingw_startup. We still need to sort on startup to make sure that the environment is sorted according to our compareenv function (while Win32 / CreateProcess requires the environment block to be sorted case-insensitively, CreateProcess currently doesn't enforce this, and some applications such as bash just don't care). Note that environment functions are _not_ thread-safe and are not required to be so by POSIX, the application is responsible for synchronizing access to the environment. MSVCRT's getenv and our new getenv implementation are better than that in that they are thread-safe with respect to other getenv calls as long as the environment is not modified. Git's indiscriminate use of getenv in background threads currently requires this property.

2014-07-21Win32: use low-level memory allocation during initializationLibravatar Karsten Blees1-15/+28
As of d41489a6 "Add more large blob test cases", git's high-level memory allocation functions (xmalloc, xmemdupz etc.) access the environment to simulate limited memory in tests (see 'getenv("GIT_ALLOC_LIMIT")' in memory_limit_check()). These functions should not be used before the environment is fully initialized (particularly not to initialize the environment itself). The current solution ('environ = NULL; ALLOC_GROW(environ...)') only works because MSVCRT's getenv() reinitializes environ when it is NULL (i.e. it leaves us with two sets of unusabe (non-UTF-8) and unfreeable (CRT- allocated) environments). Add our own set of malloc-or-die functions to be used in startup code. Also check the result of __wgetmainargs, which may fail if there's not enough memory for wide-char arguments and environment. This patch is in preparation of the sorted environment feature, which completely replaces MSVCRT's getenv() implementation.

2014-07-21Win32: don't copy the environment twice when spawning child processesLibravatar Karsten Blees2-56/+28
When spawning child processes via start_command(), the environment and all environment entries are copied twice. First by make_augmented_environ / copy_environ to merge with child_process.env. Then a second time by make_environment_block to create a sorted environment block string as required by CreateProcess. Move the merge logic to make_environment_block so that we only need to copy the environment once. This changes semantics of the env parameter: it now expects a delta (such as child_process.env) rather than a full environment. This is not a problem as the parameter is only used by start_command() (all other callers previously passed char **environ, and now pass NULL). The merge logic no longer xstrdup()s the environment strings, so do_putenv must not free them. Add a parameter to distinguish this from normal putenv. Remove the now unused make_augmented_environ / free_environ API.

2014-07-21Win32: fix environment memory leaksLibravatar Karsten Blees2-4/+7
All functions that modify the environment have memory leaks. Disable gitunsetenv in the Makefile and use env_setenv (via mingw_putenv) instead (this frees removed environment entries). Move xstrdup from env_setenv to make_augmented_environ, so that mingw_putenv no longer copies the environment entries (according to POSIX [1], "the string [...] shall become part of the environment"). This also fixes the memory leak in gitsetenv, which expects a POSIX compliant putenv. [1] http://pubs.opengroup.org/onlinepubs/009695399/functions/putenv.html Note: This patch depends on taking control of char **environ and having our own mingw_putenv (both introduced in "Win32: Unicode environment (incoming)").

2014-07-21Win32: Unicode environment (incoming)Libravatar Karsten Blees2-0/+17
Convert environment from UTF-16 to UTF-8 on startup. No changes to getenv() are necessary, as the MSVCRT version is implemented on top of char **environ. However, putenv / _wputenv from MSVCRT no longer work, for two reasons: 1. they try to keep environ, _wenviron and the Win32 process environment in sync, using the default system encoding instead of UTF-8 to convert between charsets 2. msysgit and MSVCRT use different allocators, memory allocated in git cannot be freed by the CRT and vice versa Implement mingw_putenv using the env_setenv helper function from the environment merge code. Note that in case of memory allocation failure, putenv now dies with error message (due to xrealloc) instead of failing with ENOMEM. As git assumes setenv / putenv to always succeed, this prevents it from continuing with incorrect settings.

2014-07-15Win32: Unicode file name support (except dirent)Libravatar Karsten Blees2-56/+160
Replaces Windows "ANSI" APIs dealing with file- or path names with their Unicode equivalent, adding UTF-8/UTF-16LE conversion as necessary. The dirent API (opendir/readdir/closedir) is updated in a separate commit. Adds trivial wrappers for access, chmod and chdir. Adds wrapper for mktemp (needed for both mkstemp and mkdtemp). The simplest way to convert a repository with legacy-encoded (e.g. Cp1252) file names to UTF-8 ist to checkout with an old msysgit version and "git add --all & git commit" with the new version. Includes a fix for bug reported by John Chen: On Windows XP (not Win7), directories cannot be deleted while a find handle is open, causing "Deletion of directory '...' failed. Should I try again?" prompts. Prior to this commit, these failures were silently ignored due to strbuf_free in is_dir_empty resetting GetLastError to ERROR_SUCCESS. Close the find handle in is_dir_empty so that git doesn't block deletion of the directory even after all other applications have released it.

"git status", even though it is a read-only operation, tries to update the index with refreshed lstat(2) info to optimize future accesses to the working tree opportunistically, but this could race with a "read-write" operation that modify the index while it is running. Detect such a race and avoid overwriting the index. * ym/fix-opportunistic-index-update-race: read-cache.c: verify index file before we opportunistically update it wrapper.c: add xpread() similar to xread()
