Vicent Martí 09ee60c6 2013-06-24T11:21:09 Merge pull request #1670 from arrbee/open-cloexec Add O_CLOEXEC to open calls
Russell Belfer 32c12ea6 2013-06-24T09:19:24 Work around reparse point stat issues In theory, p_stat should never return an S_ISLNK result, but due to the current implementation on Windows with mount points it is possible that it will. For now, work around that by allowing a link in the path to a directory being created. If it is really a problem, then the issue will be caught on the next iteration of the loop, but typically this will be the right thing to do.

yorah 2da72fb2 2013-06-14T12:10:13 fileops: fix invalid read
Russell Belfer f7e56150 2013-06-05T15:41:42 Make mkdir early exit cases clearer There are two places where git_futils_mkdir should exit early or at least do less. The first is when using GIT_MKDIR_SKIP_LAST and having that flag leave no directory left to create; it was being handled previously, but the behavior was subtle. Now I put in a clear explicit check that exits early in that case. The second is when there is no directory to create, but there is a valid path that should be verified. I shifted the logic a bit so we'll be better about not entering the loop than that happens.
Russell Belfer 999d4405 2013-06-05T12:02:28 Simplify git_futils_mkdir This routine was (is) pretty complicated, but given the recent changes, it seemed like it could be simplified a bit.

Russell Belfer b832ecf7 2013-06-05T09:46:51 Ensure git_futils_mkdir won't mkdir root This makes sure that git_futils_mkdir always skips over the root directory at a minimum, even on platforms where the root is not simply '/'. Also, this removes the GIT_WIN32 ifdef in favor of making EACCES as a potentially recoverable error on all platforms.
Jameson Miller daf98cb2 2013-06-04T14:49:39 Allow creation of directories under the volume root in Win32 We ran into an issue where cloning a repository to a folder directly underneath the root of a volume (e.g. 'd:\libgit2') would fail with an access denied error. This was traced down to a call to make a directory that is the root (e.g. 'd:') could return an error indicated access denied instead of an error indicating the path already exists. This change now handles the access denied error on Win32 and checks for the existence of the folder.
Russell Belfer 4742148d 2013-05-20T13:41:39 Add more diff rename detection tests This adds a bunch more rename detection tests including checks vs the working directory, the new exact match options, some more whitespace variants, etc. This also adds a git_futils_writebuffer helper function and uses it in checkout. This is mainly added because I wanted an easy way to write out a git_buf to disk inside my test code.

Russell Belfer 32460251 2013-03-18T15:54:35 Fixes and cleanups Get rid of some dead code, tighten things up a bit, and fix a bug with core::env test.
Russell Belfer 41954a49 2013-03-18T14:19:35 Switch search paths to classic delimited strings This switches the APIs for setting and getting the global/system search paths from using git_strarray to using a simple string with GIT_PATH_LIST_SEPARATOR delimited paths, just as the environment PATH variable would contain. This makes it simpler to get and set the value. I also added code to expand "$PATH" when setting a new value to embed the old value of the path. This means that I no longer require separate actions to PREPEND to the value.
Arkadiy Shapkin 10c06114 2013-03-17T04:46:46 Several warnings detected by static code analyzer fixed Implicit type conversion argument of function to size_t type Suspicious sequence of types castings: size_t -> int -> size_t Consider reviewing the expression of the 'A = B == C' kind. The expression is calculated as following: 'A = (B == C)' Unsigned type is never < 0
Russell Belfer 5540d947 2013-03-15T16:39:00 Implement global/system file search paths The goal of this work is to expose the search logic for "global", "system", and "xdg" files through the git_libgit2_opts() interface. Behind the scenes, I changed the logic for finding files to have a notion of a git_strarray that represents a search path and to store a separate search path for each of the three tiers of config file. For each tier, I implemented a function to initialize it to default values (generally based on environment variables), and then general interfaces to get it, set it, reset it, and prepend new directories to it. Next, I exposed these interfaces through the git_libgit2_opts interface, reusing the GIT_CONFIG_LEVEL_SYSTEM, etc., constants for the user to control which search path they were modifying. There are alternative designs for the opts interface / argument ordering, so I'm putting this phase out for discussion. Additionally, I ended up doing a little bit of clean up regarding attr.h and attr_file.h, adding a new attrcache.h so the other two files wouldn't have to be included in so many places.
Vicent Martí b72f5d40 2013-03-05T15:35:28 Merge pull request #1369 from arrbee/repo-init-template-hooks More tests (and fixes) for initializing repo from template
Jameson Miller 926acbcf 2013-03-01T11:07:53 Clone should not delete directories it did not create
Russell Belfer 18f08264 2013-02-27T13:44:15 Make mode handling during init more like git When creating files, instead of actually using GIT_FILEMODE_BLOB and the other various constants that happen to correspond to mode values, apparently I should be just using 0666 and 0777, and relying on the umask to clear bits and make the value sane. This fixes the rules for copying a template directory and fixes the checks to match that new behavior. (Further changes to the checkout logic to follow separately.)
Russell Belfer 3c42e4ef 2013-02-26T11:43:14 Fix initialization of repo directories When PR #1359 removed the hooks from the test resources/template directory, it made me realize that the tests for git_repository_init_ext using templates must be pretty shabby because we could not have been testing if the hooks were getting created correctly. So, this started with me recreating a couple of hooks, including a sample and symlink, and adding tests that they got created correctly in the various circumstances, including with the SHARED modes, etc. Unfortunately this uncovered some issues with how directories and symlinks were copied and chmod'ed. Also, there was a FIXME in the code related to the chmod behavior as well. Going back over the directory creation logic for setting up a repository, I found it was a little difficult to read and could result in creating and/or chmod'ing directories that the user almost certainly didn't intend. So that let to this work which makes repo initialization much more careful (and hopefully easier to follow). It required a couple of extensions / changes to core fileops utilities, but I also think those are for the better, at least for git_futils_cp_r in terms of being careful about what actions it takes.

Russell Belfer de590550 2013-01-08T17:11:11 Resolve crash with diff against empty file It is not legal inside our `p_mmap` function to mmap a zero length file. This adds a test that exercises that case inside diff and fixes the code path where we would try to do that. The fix turns out not to be a lot of code since our default file content is already initialized to "" which works in this case. Fixes #1210
Edward Thomson 359fc2d2 2013-01-08T17:07:25 update copyrights
Russell Belfer 7e5c8a5b 2012-12-10T15:31:43 More checkout improvements This flips checkout back to be driven off the changes between the baseline and the target trees. This reinstates the complex code for tracking the contents of the working directory, but overall, I think the resulting logic is easier to follow.
Russell Belfer cccacac5 2012-11-14T22:41:51 Add POSIX compat lstat() variant for win32 The existing p_lstat implementation on win32 is not quite POSIX compliant when setting errno to ENOTDIR. This adds an option to make is be compliant so that code (such as checkout) that cares to have separate behavior for ENOTDIR can use it portably. This also contains a couple of other minor cleanups in the posix_w32.c implementations to avoid unnecessary work.
Russell Belfer ad9a921b 2012-11-08T17:05:07 Rework checkout with new strategy options This is a major reworking of checkout strategy options. The checkout code is now sensitive to the contents of the HEAD tree and the new options allow you to update the working tree so that it will match the index content only when it previously matched the contents of the HEAD. This allows you to, for example, to distinguish between removing files that are in the HEAD but not in the index, vs just removing all untracked files. Because of various corner cases that arise, etc., this required some additional capabilities in rmdir and other utility functions. This includes the beginnings of an implementation of code to read a partial tree into the index based on a pathspec, but that is not enabled because of the possibility of creating conflicting index entries.
Russell Belfer 331e7de9 2012-10-24T17:32:50 Extensions to rmdir and mkdir utilities * Rework GIT_DIRREMOVAL values to GIT_RMDIR flags, allowing combinations of flags * Add GIT_RMDIR_EMPTY_PARENTS flag to remove parent dirs that are left empty after removal * Add GIT_MKDIR_VERIFY_DIR to give an error if item is a file, not a dir (previously an EEXISTS error was ignored, even for files) and enable this flag for git_futils_mkpath2file call * Improve accuracy of error messages from git_futils_mkdir

Russell Belfer c8b511f3 2012-10-31T11:26:12 Better naming for file timestamp/size checker
Russell Belfer 744cc03e 2012-10-30T12:10:36 Add git_config_refresh() API to reload config This adds a new API that allows users to reload the config if the file has changed on disk. A new config callback function to refresh the config was added. The modified time and file size are used to test if the file needs to be reloaded (and are now stored in the disk backend object). In writing tests, just using mtime was a problem / race, so I wanted to check file size as well. To support that, I extended `git_futils_readbuffer_updated` to optionally check file size in addition to mtime, and I added a new function `git_filebuf_stats` to fetch the mtime and size for an open filebuf (so that the config could be easily refreshed after a write). Lastly, I moved some similar file checking code for attributes into filebuf. It is still only being used for attrs, but it seems potentially reusable, so I thought I'd move it over.
Russell Belfer 0d422ec9 2012-10-19T15:40:43 Fix env variable tests with new Win32 path rules The new Win32 global path search was not working with the environment variable tests. But when I fixed the test, the new codes use of getenv() was causing more failures (presumably because of caching on Windows ???). This fixes the global file lookup to always go directly to the Win32 API in a predictable way.

Russell Belfer 0d64bef9 2012-10-05T15:56:57 Add complex checkout test and then fix checkout This started as a complex new test for checkout going through the "typechanges" test repository, but that revealed numerous issues with checkout, including: * complete failure with submodules * failure to create blobs with exec bits * problems when replacing a tree with a blob because the tree "example/" sorts after the blob "example" so the delete was being processed after the single file blob was created This fixes most of those problems and includes a number of other minor changes that made it easier to do that, including improving the TYPECHANGE support in diff/status, etc.

Vicent Marti c859184b 2012-09-11T23:05:24 Properly handle p_reads
Russell Belfer 1f35e89d 2012-09-11T12:03:33 Fix diff binary file detection In the process of adding tests for the max file size threshold (which treats files over a certain size as binary) there seem to be a number of problems in the new code with detecting binaries. This should fix those up, as well as add a test for the file size threshold stuff. Also, this un-deprecates `GIT_DIFF_LINE_ADD_EOFNL`, since I finally found a legitimate situation where it would be returned.
Russell Belfer 60b9d3fc 2012-09-05T15:00:40 Implement filters for status/diff blobs This adds support to diff and status for running filters (a la crlf) on blobs in the workdir before computing SHAs and before generating text diffs. This ended up being a bit more code change than I had thought since I had to reorganize some of the diff logic to minimize peak memory use when filtering blobs in a diff. This also adds a cap on the maximum size of data that will be loaded to diff. I set it at 512Mb which should match core git. Right now it is a #define in src/diff.h but it could be moved into the public API if desired.

Russell Belfer ca1b6e54 2012-07-31T17:02:54 Add template dir and set gid to repo init This extends git_repository_init_ext further with support for initializing the repository from an external template directory and with support for the "create shared" type flags that make a set GID repository directory. This also adds tests for much of the new functionality to the existing `repo/init.c` test suite. Also, this adds a bunch of new utility functions including a very general purpose `git_futils_mkdir` (with the ability to make paths and to chmod the paths post-creation) and a file tree copying function `git_futils_cp_r`. Also, this includes some new path functions that were useful to keep the code simple.
Russell Belfer 662880ca 2012-07-26T16:07:01 Add git_repository_init_ext for power initters The extended version of repository init adds support for many of the things that you can do with `git init` and sets up structures that will make it easier to extend further in the future.

Russell Belfer 7c7ff7d1 2012-03-19T16:10:11 Migrate index, oid, and utils to new errors This includes a few cleanups that came up while converting these files. This commit introduces a could new git error classes, including the catchall class: GITERR_INVALID which I'm using as the class for invalid and out of range values which are detected at too low a level of library to use a higher level classification. For example, an overflow error in parsing an integer or a bad letter in parsing an OID string would generate an error in this class.
Russell Belfer 0d0fa7c3 2012-03-16T15:56:01 Convert attr, ignore, mwindow, status to new errors Also cleaned up some previously converted code that still had little things to polish.
Russell Belfer deafee7b 2012-03-14T17:36:15 Continue error conversion This converts blob.c, fileops.c, and all of the win32 files. Also, various minor cleanups throughout the code. Plus, in testing the win32 build, I cleaned up a bunch (although not all) of the warnings with the 64-bit build.
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.

Russell Belfer 74fa4bfa 2012-02-28T16:14:47 Update diff to use iterators This is a major reorganization of the diff code. This changes the diff functions to use the iterators for traversing the content. This allowed a lot of code to be simplified. Also, this moved the functions relating to outputting a diff into a new file (diff_output.c). This includes a number of other changes - adding utility functions, extending iterators, etc. plus more tests for the diff code. This also takes the example diff.c program much further in terms of emulating git-diff command line options.
Vicent Martí 13224ea4 2012-02-27T04:28:31 buffer: Unify `git_fbuffer` and `git_buf` This makes so much sense that I can't believe it hasn't been done before. Kill the old `git_fbuffer` and read files straight into `git_buf` objects. Also: In order to fully support 4GB files in 32-bit systems, the `git_buf` implementation has been changed from using `ssize_t` for storage and storing negative values on allocation failure, to using `size_t` and changing the buffer pointer to a magical pointer on allocation failure. Hopefully this won't break anything.
Russell Belfer b6c93aef 2012-02-21T14:46:24 Uniform iterators for trees, index, and workdir This create a new git_iterator type of object that provides a uniform interface for iterating over the index, an arbitrary tree, or the working directory of a repository. As part of this, git ignore support was extended to support push and pop of directory-based ignore files as the working directory is being traversed (so the array of ignores does not have to be recreated at each directory during traveral). There are a number of other small utility functions in buffer, path, vector, and fileops that are included in this patch that made the iterator implementation cleaner.

Russell Belfer 1744fafe 2012-01-17T15:49:47 Move path related functions from fileops to path This takes all of the functions that look up simple data about paths (such as `git_futils_isdir`) and moves them over to path.h (becoming `git_path_isdir`). This leaves fileops.h just with functions that actually manipulate the filesystem or look at the file contents in some way. As part of this, the dir.h header which is really just for win32 support was moved into win32 (with some minor changes).

Russell Belfer 6a67a812 2012-01-11T16:01:48 Allow ignores (and attribs) for nonexistent files This fixes issue 532 that attributes (and gitignores) could not be checked for files that don't exist. It should be possible to query such things regardless of the existence of the file.
Russell Belfer df743c7d 2012-01-09T15:37:19 Initial implementation of gitignore support Adds support for .gitignore files to git_status_foreach() and git_status_file(). This includes refactoring the gitattributes code to share logic where possible. The GIT_STATUS_IGNORED flag will now be passed in for files that are ignored (provided they are not already in the index or the head of repo).
