* sha1_file: don't convert off_t to size_t too early to avoid potential die()sp/stream-clean-filterSteffen Prohaska2014-09-221-4/+9
| | | | | | | | | | | | xsize_t() checks if an off_t argument can be safely converted to a size_t return value. If the check is executed too early, it could fail for large files on 32-bit architectures even if the size_t code path is not taken. Other paths might be able to handle the large file. Specifically, index_stream_convert_blob() is able to handle a large file if a filter is configured that returns a small result.

* convert: stream from fd to required clean filter to reduce used address spaceSteffen Prohaska2014-08-284-12/+99
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The data is streamed to the filter process anyway. Better avoid mapping the file if possible. This is especially useful if a clean filter reduces the size, for example if it computes a sha1 for binary data, like git media. The file size that the previous implementation could handle was limited by the available address space; large files for example could not be handled with (32-bit) msysgit. The new implementation can filter files of any size as long as the filter output is small enough. The new code path is only taken if the filter is required. The filter consumes data directly from the fd. If it fails, the original data is not immediately available. The condition can easily be handled as a fatal error, which is expected for a required filter anyway. If the filter was not required, the condition would need to be handled in a different way, like seeking to 0 and reading the data. But this would require more restructuring of the code and is probably not worth it. The obvious approach of falling back to reading all data would not help achieving the main purpose of this patch, which is to handle large files with limited address space. If reading all data is an option, we can simply take the old code path right away and mmap the entire file. The environment variable GIT_MMAP_LIMIT, which has been introduced in a previous commit is used to test that the expected code path is taken. A related test that exercises required filters is modified to verify that the data actually has been modified on its way from the file system to the object store.

* copy_fd(): do not close the input file descriptorSteffen Prohaska2014-08-282-21/+8
| | | | | | | | | | | | | | The caller, not this function, opened the file descriptor; it is selfish for the callee to close it when it is done reading from it. The caller may want an option to rewind and re-read the contents after it returns. Simplify the loop to copy the input in full to the output; its body essentially is what a call to write_in_full() helper does.

* mmap_limit: introduce GIT_MMAP_LIMIT to allow testing expected mmap sizeSteffen Prohaska2014-08-281-1/+17
| | | | | | | | | | | | | | | In order to test expectations about mmap in a way similar to testing expectations about malloc with GIT_ALLOC_LIMIT introduced by d41489a6 (Add more large blob test cases, 2012-03-07), introduce a new environment variable GIT_MMAP_LIMIT to limit the largest allowed mmap length. xmmap() is modified to check the size of the requested region and fail it if it is beyond the limit. Together with GIT_ALLOC_LIMIT tests can now confirm expectations about memory consumption. Signed-off-by: Steffen Prohaska <prohaska@zib.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* memory_limit: use git_env_ulong() to parse GIT_ALLOC_LIMITSteffen Prohaska2014-08-282-8/+9
| | | | | | | | | | | | | | | GIT_ALLOC_LIMIT limits xmalloc()'s size, which is of type size_t. Better use git_env_ulong() to parse the environment variable, so that the postfixes 'k', 'm', and 'g' can be used; and use size_t to store the limit for consistency. The change to size_t has no direct practical impact, because the environment variable is only meant to be used for our own tests, and we use it to test small sizes. The cast of size in the call to die() is changed to uintmax_t to match the format string PRIuMAX. Signed-off-by: Steffen Prohaska <prohaska@zib.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

So hard, indeed, that git blame -L/hello/,/green/ is translated into something like git blame -LC:/msysgit/hello/,C:/msysgit/green/ As seen in msys_p2w in src\msys\msys\rt\src\winsup\cygwin\path.cc, line 3204ff: case '-': // // here we check for POSIX paths as attributes to a POSIX switch. // ... seemingly absolute POSIX paths in single-letter options get expanded by msys.dll unless they contain '=' or ';'. So a quick and very dirty fix is to use '-L/;*evil/'. (Using an equal sign works only when it is before a comma, so in the above example, /=*green/ would still be converted to a DOS-style path.) The -L mangling can be done by the script, just before the parameter is passed to the executable. This version does not modify the body of the tests and is active on MinGW only.

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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | | | | | Win32: unify environment function namesKarsten Blees2014-07-211-7/+7

Change to POSIX naming scheme ('env' suffix, no '_'). Env_setenv has more in common with putenv than setenv. Change to do_putenv.

| * | | | | | Win32: unify environment case-sensitivityKarsten Blees2014-07-211-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The environment on Windows is case-insensitive. Some environment functions (such as unsetenv and make_augmented_environ) have always used case- sensitive comparisons instead, while others (getenv, putenv, sorting in spawn*) were case-insensitive. Prevent potential inconsistencies by using case-insensitive comparison in lookup_env (used by putenv, unsetenv and make_augmented_environ).

| * | | | | | Win32: fix environment memory leaksKarsten Blees2014-07-213-6/+7

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)").

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.
