Russell Belfer 98527b5b 2013-01-09T16:03:35 Add git_tree_entry_cmp and git_tree_entry_icmp This adds a new external API git_tree_entry_cmp and a new internal API git_tree_entry_icmp for sorting tree entries. The case insensitive one is internal only because general users should never be seeing case-insensitively sorted trees.

Russell Belfer 91e7d263 2012-12-10T15:29:44 Fix iterator reset and add reset ranges The `git_iterator_reset` command has not been working in all cases particularly when there is a start and end range. This fixes it and adds tests for it, and also extends it with the ability to update the start/end range strings when an iterator is reset.
Russell Belfer 9950d27a 2012-12-06T13:26:58 Clean up iterator APIs This removes the need to explicitly pass the repo into iterators where the repo is implied by the other parameters. This moves the repo to be owned by the parent struct. Also, this has some iterator related updates to the internal diff API to lay the groundwork for checkout improvements.
Carlos Martín Nieto f1c75b94 2012-12-07T15:16:41 tree: relax the filemode parser There are many different broken filemodes in the wild so we need to protect against them and give something useful up the chain. Don't fail when reading a tree from the ODB but normalize the mode as best we can. As 664 is no longer a mode that we consider to be valid and gets normalized to 644, we can stop accepting it in the treebuilder. The library won't expose it to the user, so any invalid modes are a bug.

Russell Belfer 16248ee2 2012-11-21T11:03:07 Fix up some missing consts in tree & index This fixes some missed places where we can apply const-ness to various public APIs. There are still some index and tree APIs that cannot take const pointers because we sort our `git_vectors` lazily and so we can't reliably bsearch the index and tree content without applying a `git_vector_sort()` first. This also fixes some missed places where size_t can be used and where const can be applied to a couple internal functions.

Russell Belfer cfeef7ce 2012-11-19T13:40:08 Minor optimization to tree entry validity check This checks for a leading '.' before looking for the invalid tree entry names. Even on pretty high levels of optimization, this seems to make a measurable improvement. I accidentally used && in the check initially instead of || and while debugging ended up improving the error reporting of issues with adding tree entries. I thought I'd leave those changes, too.

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.

Carlos Martín Nieto a6bf1687 2012-08-13T14:07:47 tree: allow the user to skip an entry or cancel the walk Returning a negative cancels the walk, and returning a positive one causes us to skip an entry, which was previously done by a negative value. This allows us to stay consistent with the rest of the functions that take a callback and keeps the skipping functionality.

Russell Belfer 2031760c 2012-07-26T16:10:22 Fix git_tree_walk to return user error This makes sure that an error code returned by the callback function of `git_tree_walk` will stop the iteration and get propagated back to the caller verbatim. Also, this adds a minor helper function `git_tree_entry_byoid` that searches a `git_tree` for an entry with the given OID. This isn't a fast function, but it's easier than writing the loop yourself as an external user of the library.

Russell Belfer 41a82592 2012-05-15T14:17:39 Ranged iterators and rewritten git_status_file The goal of this work is to rewrite git_status_file to use the same underlying code as git_status_foreach. This is done in 3 phases: 1. Extend iterators to allow ranged iteration with start and end prefixes for the range of file names to be covered. 2. Improve diff so that when there is a pathspec and there is a common non-wildcard prefix of the pathspec, it will use ranged iterators to minimize excess iteration. 3. Rewrite git_status_file to call git_status_foreach_ext with a pathspec that covers just the one file being checked. Since ranged iterators underlie the status & diff implementation, this is actually fairly efficient. The workdir iterator does end up loading the contents of all the directories down to the single file, which should ideally be avoided, but it is pretty good.

Note that in most of the places were it has been dropped, the code needs cleanup. I.e. GIT_ENOMEM is going away, so instead it should return a generic `-1` and obviously not throw anything.

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).
Clemens Buchacher 1f783edf 2011-12-29T15:03:38 do not use full path in diff-index Currently, diff_index passes the full relative path from the repository root to the callback. In case of an addition, it passes the tree entry instead of the index entry. This change fixes the path used for addition, and it passes only the basename of the path. This mimics the current behavior of git_tree_diff.

Russell Belfer 97769280 2011-11-30T11:27:15 Use git_buf for path storage instead of stack-based buffers This converts virtually all of the places that allocate GIT_PATH_MAX buffers on the stack for manipulating paths to use git_buf objects instead. The patch is pretty careful not to touch the public API for libgit2, so there are a few places that still use GIT_PATH_MAX. This extends and changes some details of the git_buf implementation to add a couple of extra functions and to make error handling easier. This includes serious alterations to all the path.c functions, and several of the fileops.c ones, too. Also, there are a number of new functions that parallel existing ones except that use a git_buf instead of a stack-based buffer (such as git_config_find_global_r that exists alongsize git_config_find_global). This also modifies the win32 version of p_realpath to allocate whatever buffer size is needed to accommodate the realpath instead of hardcoding a GIT_PATH_MAX limit, but that change needs to be tested still.

Vicent Marti 9462c471 2011-11-25T08:16:26 repository: Change ownership semantics The ownership semantics have been changed all over the library to be consistent. There are no more "borrowed" or duplicated references. Main changes: - `git_repository_open2` and `3` have been dropped. - Added setters and getters to hotswap all the repository owned objects: `git_repository_index` `git_repository_set_index` `git_repository_odb` `git_repository_set_odb` `git_repository_config` `git_repository_set_config` `git_repository_workdir` `git_repository_set_workdir` Now working directories/index files/ODBs and so on can be hot-swapped after creating a repository and between operations. - All these objects now have proper ownership semantics with refcounting: they all require freeing after they are no longer needed (the repository always keeps its internal reference). - Repository open and initialization has been updated to keep in mind the configuration files. Bare repositories are now always detected, and a default config file is created on init. - All the tests affected by these changes have been dropped from the old test suite and ported to the new one.

Vicent Marti e6629d83 2011-07-13T03:36:03 tree: More accurate matching on entries The old matcher was returning fake matches when given stupid entry names. E.g. `git2` could be matched by `git2 /`, `git2/foobar`, git2/////` and other stupid stuff
Vicent Marti 761aa2aa 2011-07-13T02:49:47 tree: Fix wrong sort order when querying entries Fixes #127 (that was quite an outstanding issue). Rationale: The tree objects on Git are stored and read following a very specific sorting algorithm that places folders before files. That original sort was the sort we were storing on memory, but this sort was being queried with a binary search that used a simple `strcmp` for comparison, so there were many instances where the search was failing. Obviously, the most straightforward way to fix this is changing the binary search CB to use the same comparison method as the sorting CB. The problem with this is that the binary search callback compares a path and an entry, so there is no way to know if the given path is a folder or a standard file. How do we work around this? Instead of splitting the `entry_byname` method in two (one for searching directories and one for searching normal files), we just assume that the path we are searching for is of the same kind as the path it's being compared at the moment. return git_futils_cmp_path( ksearch->filename, ksearch->filename_len, entry->attr & 040000, entry->filename, entry->filename_len, entry->attr & 040000); Since there cannot be a folder and a regular file with the same name on the same tree, the most basic equality check will always fail for all comparsions, until our path is compared with the actual entry we are looking for; in this case, the matching will succeed with the file type of the entry -- whatever it was initially. I hope that makes sense. PS: While I was at it, I switched the cmp methods to use cached values for the length of each filename. That makes searches and sorts retardedly fast -- I was wondering the reason of the performance hiccups on massive trees; it's because of 2*strlen for each comparsion call.
Vicent Marti afeecf4f 2011-07-09T02:10:46 odb: Direct writes are back DIRECT WRITES ARE BACK AND FASTER THAN EVER. The streaming writer to the ODB was an overkill for the smaller objects like Commit and Tags; most of the streaming logic was taking too long. This commit makes Commits, Tags and Trees to be built-up in memory, and then written to disk in 2 pushes (header + data), instead of streaming everything. This is *always* faster, even for big files (since the git_filebuf class still does streaming writes when the memory cache overflows). This is also a gazillion lines of code smaller, because we don't have to precompute the final size of the object before starting the stream (this was kind of defeating the point of streaming, anyway). Blobs are still written with full streaming instead of loading them in memory, since this is still the fastest way. A new `git_buf` class has been added. It's missing some features, but it'll get there.
Vicent Marti de18f276 2011-07-07T01:46:20 vector: Timsort all of the things Drop the GLibc implementation of Merge Sort and replace it with Timsort. The algorithm has been tuned to work on arrays of pointers (void **), so there's no longer a need to abstract the byte-width of each element in the array. All the comparison callbacks now take pointers-to-elements, not pointers-to-pointers, so there's now one less level of dereferencing. E.g. int index_cmp(const void *a, const void *b) { - const git_index_entry *entry_a = *(const git_index_entry **)(a); + const git_index_entry *entry_a = (const git_index_entry *)(a); The result is up to a 40% speed-up when sorting vectors. Memory usage remains lineal. A new `bsearch` implementation has been added, whose callback also supplies pointer-to-elements, to uniform the Vector API again.
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.
