Vicent Marti 858dba58 2011-07-06T18:08:13 refs: Cleanup reference renaming `git_futils_rmdir_r`: rename, clean up. `git_reference_rename`: cleanup. Do not use 3x4096 buffers on the stack or things will get ugly very fast. We can reuse the same buffer.

Vicent Marti eec3fe39 2011-07-05T01:11:33 fileutils: Finish dropping the old `prettify_path`
Vicent Marti 19ac1ed7 2011-07-04T21:33:26 fileops: Fix stat() on directories for W32 The `stat` methods were having issues when called with a trailing slash in Windows platforms. We now use GetFileAttributes() where possible, which doesn't have this restriction.
Vicent Marti 5ad739e8 2011-07-04T20:05:11 fileops: Drop `git_fileops_prettify_path` The old `git_fileops_prettify_path` has been replaced with `git_path_prettify`. This is a much simpler method that uses the OS's `realpath` call to obtain the full path for directories and resolve symlinks. The `realpath` syscall is the original POSIX call in Unix system and an emulated version under Windows using the Windows API.
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.

Vicent Martí 275c6a0b 2011-06-07T07:03:14 Merge pull request #242 from schu/fix-unused-2 fileops.c: fix unused warning v2
Jakob Pfender fdd1e04c 2011-06-07T14:10:06 fileops: Allow differentiation between deep and shallow exists() When calling gitfo_exists() on a symbolic link, sometimes we need to simply check whether the link exists and sometimes we need to check whether the file pointed to by the symlink exists. Introduce a new function gitfo_shallow_exists that only checks if the link exists and revert gitfo_exists to the original functionality of checking whether the file pointed to by the link exists.
Jakob Pfender 1869b31e 2011-05-25T16:11:57 index/fileops: Correctly process symbolic links gitfo_exists() used to error out if the given file was a symbolic link, due to access() returning an error code. This is not expected behaviour, as gitfo_exists() should only check whether the file itself exists, not its link target if it is a symbolic link. Fix this by calling gitfo_lstat() instead, which is just a wrapper for lstat(). Also fix the same error in index_init_entry().

Romain Geissler a993e4fe 2011-06-05T00:20:35 Fileops: Fixed gitfo_mkdir_recurs so that it proprely works with a path without trailing slash. It used to discard the last directory if the path didn't have a trailing slash.
Romain Geissler f2e6b877 2011-06-03T23:44:38 Repository: Added some util functions that we'll need to discover repository path. retrieve_device returns the file device for a given path (so that we can detect device change while walking through parent directories). abspath returns a canonicalized path, symbolic link free. retrieive_ceiling_directories_offset returns the biggest path offset that path match in the ceiling directory list (so that we can stop at ceiling directories).

Vicent Marti 72a3fe42 2011-03-18T19:38:49 I broke your bindings Hey. Apologies in advance -- I broke your bindings. This is a major commit that includes a long-overdue redesign of the whole object-database structure. This is expected to be the last major external API redesign of the library until the first non-alpha release. Please get your bindings up to date with these changes. They will be included in the next minor release. Sorry again! Major features include: - Real caching and refcounting on parsed objects - Real caching and refcounting on objects read from the ODB - Streaming writes & reads from the ODB - Single-method writes for all object types - The external API is now partially thread-safe The speed increases are significant in all aspects, specially when reading an object several times from the ODB (revwalking) and when writing big objects to the ODB. Here's a full changelog for the external API: blob.h ------ - Remove `git_blob_new` - Remove `git_blob_set_rawcontent` - Remove `git_blob_set_rawcontent_fromfile` - Rename `git_blob_writefile` -> `git_blob_create_fromfile` - Change `git_blob_create_fromfile`: The `path` argument is now relative to the repository's working dir - Add `git_blob_create_frombuffer` commit.h -------- - Remove `git_commit_new` - Remove `git_commit_add_parent` - Remove `git_commit_set_message` - Remove `git_commit_set_committer` - Remove `git_commit_set_author` - Remove `git_commit_set_tree` - Add `git_commit_create` - Add `git_commit_create_v` - Add `git_commit_create_o` - Add `git_commit_create_ov` tag.h ----- - Remove `git_tag_new` - Remove `git_tag_set_target` - Remove `git_tag_set_name` - Remove `git_tag_set_tagger` - Remove `git_tag_set_message` - Add `git_tag_create` - Add `git_tag_create_o` tree.h ------ - Change `git_tree_entry_2object`: New signature is `(git_object **object_out, git_repository *repo, git_tree_entry *entry)` - Remove `git_tree_new` - Remove `git_tree_add_entry` - Remove `git_tree_remove_entry_byindex` - Remove `git_tree_remove_entry_byname` - Remove `git_tree_clearentries` - Remove `git_tree_entry_set_id` - Remove `git_tree_entry_set_name` - Remove `git_tree_entry_set_attributes` object.h ------------ - Remove `git_object_new - Remove `git_object_write` - Change `git_object_close`: This method is now *mandatory*. Not closing an object causes a memory leak. odb.h ----- - Remove type `git_rawobj` - Remove `git_rawobj_close` - Rename `git_rawobj_hash` -> `git_odb_hash` - Change `git_odb_hash`: New signature is `(git_oid *id, const void *data, size_t len, git_otype type)` - Add type `git_odb_object` - Add `git_odb_object_close` - Change `git_odb_read`: New signature is `(git_odb_object **out, git_odb *db, const git_oid *id)` - Change `git_odb_read_header`: New signature is `(size_t *len_p, git_otype *type_p, git_odb *db, const git_oid *id)` - Remove `git_odb_write` - Add `git_odb_open_wstream` - Add `git_odb_open_rstream` odb_backend.h ------------- - Change type `git_odb_backend`: New internal signatures are as follows int (* read)(void **, size_t *, git_otype *, struct git_odb_backend *, const git_oid *) int (* read_header)(size_t *, git_otype *, struct git_odb_backend *, const git_oid *) int (* writestream)(struct git_odb_stream **, struct git_odb_backend *, size_t, git_otype) int (* readstream)( struct git_odb_stream **, struct git_odb_backend *, const git_oid *) - Add type `git_odb_stream` - Add enum `git_odb_streammode` Signed-off-by: Vicent Marti <tanoku@gmail.com>

Vicent Marti b5e567b9 2011-01-19T17:15:02 Merge branch 'dir-path-prettifying' of https://github.com/nulltoken/libgit2
nulltoken 170d3f2f 2011-01-11T20:12:53 Added git_prettify_dir_path(). Clean up a provided absolute or relative directory path. This prettification relies on basic operations such as coalescing multiple forward slashes into a single slash, removing '.' and './' current directory segments, and removing parent directory whenever '..' is encountered. If not empty, the returned path ends with a forward slash. For instance, this will turn "d1/s1///s2/..//../s3" into "d1/s3/". This only performs a string based analysis of the path. No checks are done to make sure the path actually makes sense from the file system perspective.
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.

Shawn O. Pearce 5690f02e 2008-12-31T15:35:36 Rewrite git_foreach_dirent into gitfo_dirent Our fileops API is currently private. We aren't planning on supplying a cross-platform file API to applications that link to us. If we did, we'd probably whole-sale publish fileops, not just the dirent code. By moving it to be private we can also change the call signature to permit the buffer to be passed down through the call chain. This is very helpful when we are doing a recursive scan as we can reuse just one buffer in all stack frames, reducing the impact the recursion has on the stack frames in the data cache.

Pearce 7dd8a9f7 2008-12-30T23:26:38 Set GIT_EOSERR when the OS errno should be consulted This error code indicates the OS error code has a better value describing the last error, as it is likely a network or local file IO problem identified by a C library function call.

Shawn O. Pearce 64a47c01 2008-12-30T23:21:36 Wrap malloc and friends and report out of memory as GIT_ENOMEM We now forbid direct use of malloc, strdup or calloc within the library and instead use wrapper functions git__malloc, etc. to invoke the underlying library malloc and set git_errno to a no memory error code if the allocation fails. In the future once we have pack objects in memory we are likely to enhance these routines with garbage collection logic to purge cached pack data when allocations fail. Because the size of the function will grow somewhat large, we don't want to mark them for inline as gcc tends to aggressively inline, creating larger than expected executables.

Ramsay Jones 42fd40db 2008-12-27T18:56:16 Fix a bug in gitfo_read_file() In particular, when asked to read an empty file, this function calls malloc() with a zero size allocation request. Standard C says that the behaviour of malloc() in this case is implementation defined. [C99, 7.20.3 says "... If the size of the space requested is zero, the behavior is implementation-defined: either a null pointer is returned, or the behavior is as if the size were some nonzero value, except that the returned pointer shall not be used to access an object."] Finesse the issue by over-allocating by one byte. Setting the extra byte to '\0' may also provide a useful sentinel for text files. Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk> Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
Ramsay Jones 75d58430 2008-12-18T22:56:14 Add a file reading routine along with an io buffer type In particular, the gitfo_read_file() routine can be used to slurp the complete file contents into an gitfo_buf structure. The buffer content will be allocated by malloc() and may be released by the gitfo_free_buf() routine. The io buffer type can be initialised on the stack with the GITFO_BUF_INIT macro.

Ramsay Jones 5ee2fe77 2008-12-03T23:53:55 Add a GIT_PATH_MAX constant The PATH_MAX symbol is often, but not always, defined in the <limits.h> header. In particular, on cygwin you need to include this header to avoid a compilation error. However, some systems define PATH_MAX to be something as small as 256, which POSIX is happy to allow, while others allow much larger values. In general it can vary from one filesystem to another. In order to avoid the vagaries of different systems, define our own symbol. Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk> Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
Andreas Ericsson ea790f33 2008-11-29T15:34:20 Add a dirent walker to the fileops API Since at least MS have something like GetFirstDirEnt() and GetNextDirEnt() (presumably with superior performance), we can let MS hackers add support for a dirent walker using that API instead, while we stick with the posix-style readdir() calls.

Andreas Ericsson 4188d28f 2008-11-29T15:28:12 Add an io caching layer to the gitfo api The idea is taken from Junio's work in read-cache.c, where it's used for writing out the index without tap-dancing on the poor harddrive. Since it's almost certainly useful for cached writing of packfiles too, we turn it into a generic API, making it perfectly simple to reuse it later. gitfo_write_cached() has the same contract as gitfo_write(), it returns GIT_SUCCESS if all bytes are successfully written (or were at least buffered for later writing), and <0 if an error occurs during buffer writing.

Andreas Ericsson ec250c6e 2008-11-23T22:37:55 Remove config.h and make fileops an internal API Since it doesn't make sense to make the disk access stuff portable *AND* public (that's a job for each application imo), we can take a shortcut and just support unixy stuff for now and get away with coding most of it as macros. Since we go with an internal API for starters and only provide higher-level API's to the libgit users, we'll be ok with this approach.
