Edward Thomson c6ebdb29 2020-11-22T09:43:06 win32: use GIT_ASSERT
Edward Thomson 8be12026 2019-06-23T17:09:22 mmap: use a 64-bit signed type `off64_t` for mmap Prefer `off64_t` to `git_off_t` for internal visibility.
Edward Thomson 7e1cc296 2019-11-25T13:17:42 mmap: remove unnecessary assertion 64 bit types are always 64 bit.
Edward Thomson f673e232 2018-12-27T13:47:34 git_error: use new names in internal APIs and usage Move to the `git_error` name in the internal API for error-related functions.
Patrick Steinhardt 0c7f49dd 2017-06-30T13:39:01 Make sure to always include "common.h" first Next to including several files, our "common.h" header also declares various macros which are then used throughout the project. As such, we have to make sure to always include this file first in all implementation files. Otherwise, we might encounter problems or even silent behavioural differences due to macros or defines not being defined as they should be. So in fact, our header and implementation files should make sure to always include "common.h" first. This commit does so by establishing a common include pattern. Header files inside of "src" will now always include "common.h" as its first other file, separated by a newline from all the other includes to make it stand out as special. There are two cases for the implementation files. If they do have a matching header file, they will always include this one first, leading to "common.h" being transitively included as first file. If they do not have a matching header file, they instead include "common.h" as first file themselves. This fixes the outlined problems and will become our standard practice for header and source files inside of the "src/" from now on.
Edward Thomson 909d5494 2016-12-29T12:25:15 giterr_set: consistent error messages Error messages should be sentence fragments, and therefore: 1. Should not begin with a capital letter, 2. Should not conclude with punctuation, and 3. Should not end a sentence and begin a new one
Carlos Martín Nieto 87c18197 2016-03-16T19:05:11 Split the page size from the mmap alignment While often similar, these are not the same on Windows. We want to use the page size on Windows for the pools, but for mmap we need to use the allocation granularity as the alignment. On the other platforms these values remain the same.
Albert Meltzer 62e562f9 2014-05-18T07:54:41 Fix compiler warning (git_off_t cast to size_t). Use size_t for page size, instead of long. Check result of sysconf. Use size_t for page offset so no cast to size_t (second arg to p_mmap). Use mod instead div/mult pair, so no cast to size_t is necessary.
Carlos Martín Nieto f7310540 2014-05-13T02:41:48 indexer: use mmap for writing Some OSs cannot keep their ideas about file content straight when mixing standard IO with file mapping. As we use mmap for reading from the packfile, let's make writing to the pack file use mmap.
Russell Belfer 7697e541 2013-12-11T15:02:20 Test cancel from indexer progress callback This adds tests that try canceling an indexer operation from within the progress callback. After writing the tests, I wanted to run this under valgrind and had a number of errors in that situation because mmap wasn't working. I added a CMake option to force emulation of mmap and consolidated the Amiga-specific code into that new place (so we don't actually need separate Amiga code now, just have to turn on -DNO_MMAP). Additionally, I made the indexer code propagate error codes more reliably than it used to.

Russell Belfer e3c47510 2012-03-13T14:23:24 Resolve comments from pull request This converts the map validation function into a macro, tweaks the GITERR_OS system error automatic appending, and adds a tentative new error access API and some quick unit tests for both the old and new error APIs.
Russell Belfer e1de726c 2012-03-12T22:55:40 Migrate ODB files to new error handling This migrates odb.c, odb_loose.c, odb_pack.c and pack.c to the new style of error handling. Also got the unix and win32 versions of map.c. There are some minor changes to other files but no others were completely converted. This also contains an update to filebuf so that a zeroed out filebuf will not think that the fd (== 0) is actually open (and inadvertently call close() on fd 0 if cleaned up). Lastly, this was built and tested on win32 and contains a bunch of fixes for the win32 build which was pretty broken.

Vicent Marti 87d9869f 2011-09-19T03:34:49 Tabify everything There were quite a few places were spaces were being used instead of tabs. Try to catch them all. This should hopefully not break anything. Except for `git blame`. Oh well.
Vicent Marti bb742ede 2011-09-19T01:54:32 Cleanup legal data 1. The license header is technically not valid if it doesn't have a copyright signature. 2. The COPYING file has been updated with the different licenses used in the project. 3. The full GPLv2 header in each file annoys me.
Vicent Marti f79026b4 2011-07-04T11:43:34 fileops: Cleanup Cleaned up the structure of the whole OS-abstraction layer. fileops.c now contains a set of utility methods for file management used by the library. These are abstractions on top of the original POSIX calls. There's a new file called `posix.c` that contains emulations/reimplementations of all the POSIX calls the library uses. These are prefixed with `p_`. There's a specific posix file for each platform (win32 and unix). All the path-related methods have been moved from `utils.c` to `path.c` and have their own prefix.

Alex Budovski f0bde7fa 2011-01-11T16:07:45 Revised platform types to use 'best supported' size. This will allow graceful migration to 64 bit file sizes and timestamps should git's binary interface be extended to allow this.

Ramsay Jones 79ca2edc 2009-03-20T19:51:48 win32: Add routines to abstract memory-mapped file functions In particular, the git__mmap() and git__munmap() routines provide the interface to platform specific memory-mapped file facilities. We provide implementations for unix and win32, which can be found in their own sub-directories. Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk> Signed-off-by: Shawn O.
