Russell Belfer c2b67043 2012-04-25T15:20:28 Rename git_khash_str to git_strmap, etc. This renamed `git_khash_str` to `git_strmap`, `git_hash_oid` to `git_oidmap`, and deletes `git_hashtable` from the tree, plus adds unit tests for `git_strmap`.
Russell Belfer 01fed0a8 2012-04-25T10:36:01 Convert hashtable usage over to khash This updates khash.h with some extra features (like error checking on allocations, ability to use wrapped malloc, foreach calls, etc), creates two high-level wrappers around khash: `git_khash_str` and `git_khash_oid` for string-to-void-ptr and oid-to-void-ptr tables, then converts all of the old usage of `git_hashtable` over to use these new hashtables. For `git_khash_str`, I've tried to create a set of macros that yield an API not too unlike the old `git_hashtable` API. Since the oid hashtable is only used in one file, I haven't bother to set up all those macros and just use the khash APIs directly for now.
Russell Belfer 2bc8fa02 2012-04-17T10:14:24 Implement git_pool paged memory allocator This adds a `git_pool` object that can do simple paged memory allocation with free for the entire pool at once. Using this, you can replace many small allocations with large blocks that can then cheaply be doled out in small pieces. This is best used when you plan to free the small blocks all at once - for example, if they represent the parsed state from a file or data stream that are either all kept or all discarded. There are two real patterns of usage for `git_pools`: either for "string" allocation, where the item size is a single byte and you end up just packing the allocations in together, or for "fixed size" allocation where you are allocating a large object (e.g. a `git_oid`) and you generally just allocation single objects that can be tightly packed. Of course, you can use it for other things, but those two cases are the easiest.
Russell Belfer 26515e73 2012-04-23T10:06:31 Rename to git_reference_name_to_oid
Russell Belfer 44ef8b1b 2012-04-13T13:00:10 Fix warnings on 64-bit windows builds This fixes all the warnings on win64 except those in deps, which come from the regex code.
Russell Belfer f201d613 2012-04-13T10:33:14 Add git_reference_lookup_oid and lookup_resolved Adds a new public reference function `git_reference_lookup_oid` that directly resolved a reference name to an OID without returning the intermediate `git_reference` object (hence, no free needed). Internally, this adds a `git_reference_lookup_resolved` function that combines looking up and resolving a reference. This allows us to be more efficient with memory reallocation. The existing `git_reference_lookup` and `git_reference_resolve` are reimplmented on top of the new utility and a few places in the code are changed to use one of the two new functions.
nulltoken 4615f0f7 2012-04-09T03:22:14 branch: add git_branch_move()
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 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 ae9e29fd 2012-03-06T16:14:31 Migrating diff to new error handling Ended up migrating a bunch of upstream functions as well including vector, attr_file, and odb in order to get this to work right.

Vicent Martí 45d387ac 2012-02-15T16:54:17 refs: Error handling rework. WIP
Russell Belfer 854eccbb 2012-02-29T12:04:59 Clean up GIT_UNUSED macros on all platforms It turns out that commit 31e9cfc4cbcaf1b38cdd3dbe3282a8f57e5366a5 did not fix the GIT_USUSED behavior on all platforms. This commit walks through and really cleans things up more thoroughly, getting rid of the unnecessary stuff. To remove the use of some GIT_UNUSED, I ended up adding a couple of new iterators for hashtables that allow you to iterator just over keys or just over values. In making this change, I found a bug in the clar tests (where we were doing *count++ but meant to do (*count)++ to increment the value). I fixed that but then found the test failing because it was not really using an empty repo. So, I took some of the code that I wrote for iterator testing and moved it to clar_helpers.c, then made use of that to make it easier to open fixtures on a per test basis even within a single test file.
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 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 ee1f0b1a 2011-12-16T10:56:43 Add APIs for git attributes This adds APIs for querying git attributes. In addition to the new API in include/git2/attr.h, most of the action is in src/attr_file.[hc] which contains utilities for dealing with a single attributes file, and src/attr.[hc] which contains the implementation of the APIs that merge all applicable attributes files.
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 45e79e37 2011-11-26T04:59:21 Rename all `_close` methods There's no difference between `_free` and `_close` semantics: keep everything with the same name to avoid confusions.
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 d4a0b124 2011-10-30T21:58:33 refs: Partial rewrite for read-only refs This new version of the references code is significantly faster and hopefully easier to read. External API stays the same. A new method `git_reference_reload()` has been added to force updating a memory reference from disk. In-memory references are no longer updated automagically -- this was killing us. If a reference is deleted externally and the user doesn't reload the memory object, nothing critical happens: any functions using that reference should fail gracefully (e.g. deletion, renaming, and so on). All generated references from the API are read only and must be free'd by the user. There is no reference counting and no traces of generated references are kept in the library. There is no longer an internal representation for references. There is only one reference struct `git_reference`, and symbolic/oid targets are stored inside an union. Packfile references are stored using an optimized struct with flex array for reference names. This should significantly reduce the memory cost of loading the packfile from disk.

Brodie Rao 01ad7b3a 2011-09-06T15:48:45 *: correct and codify various file permissions The following files now have 0444 permissions: - loose objects - pack indexes - pack files - packs downloaded by fetch - packs downloaded by the HTTP transport And the following files now have 0666 permissions: - config files - repository indexes - reflogs - refs This brings libgit2 more in line with Git. Note that git_filebuf_commit() and git_filebuf_commit_at() have both gained a new mode parameter. The latter change fixes an important issue where filebufs created with GIT_FILEBUF_TEMPORARY received 0600 permissions (due to mkstemp(3) usage). Now we chmod() the file before renaming it into place. Tests have been added to confirm that new commit, tag, and tree objects are created with the right permissions. I don't have access to Windows, so for now I've guarded the tests with "#ifndef GIT_WIN32".

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 fa59f18d 2011-05-09T20:54:04 Change error handling mechanism once again Ok, this is the real deal. Hopefully. Here's how it's going to work: - One main method, called `git__throw`, that sets the error code and error message when an error happens. This method must be called in every single place where an error code was being returned previously, setting an error message instead. Example, instead of: return GIT_EOBJCORRUPTED; Use: return git__throw(GIT_EOBJCORRUPTED, "The object is missing a finalizing line feed"); And instead of: [...] { error = GIT_EOBJCORRUPTED; goto cleanup; } Use: [...] { error = git__throw(GIT_EOBJCORRUPTED, "What an error!"); goto cleanup; } The **only** exception to this are the allocation methods, which return NULL on failure but already set the message manually. /* only place where an error code can be returned directly, because the error message has already been set by the wrapper */ if (foo == NULL) return GIT_ENOMEM; - One secondary method, called `git__rethrow`, which can be used to fine-grain an error message and build an error stack. Example, instead of: if ((error = foobar(baz)) < GIT_SUCCESS) return error; You can now do: if ((error = foobar(baz)) < GIT_SUCCESS) return git__rethrow(error, "Failed to do a major operation"); The return of the `git_lasterror` method will be a string in the shape of: "Failed to do a major operation. (Failed to do an internal operation)" E.g. "Failed to open the index. (Not enough permissions to access '/path/to/index')." NOTE: do not abuse this method. Try to write all `git__throw` messages in a descriptive manner, to avoid having to rethrow them to clarify their meaning. This method should only be used in the places where the original error message set by a subroutine is not specific enough. It is encouraged to continue using this style as much possible to enforce error propagation: if ((error = foobar(baz)) < GIT_SUCCESS) return error; /* `foobar` has set an error message, and we are just propagating it */ The error handling revamp will take place in two phases: - Phase 1: Replace all pieces of code that return direct error codes with calls to `git__throw`. This can be done semi-automatically using `ack` to locate all the error codes that must be replaced. - Phase 2: Add some `git__rethrow` calls in those cases where the original error messages are not specific enough. Phase 1 is the main goal. A minor libgit2 release will be shipped once Phase 1 is ready, and the work will start on gradually improving the error handling mechanism by refining specific error messages. OTHER NOTES: - When writing error messages, please refrain from using weasel words. They add verbosity to the message without giving any real information. (<3 Emeric) E.g. "The reference file appears to be missing a carriage return" Nope. "The reference file is missing a carriage return" Yes. - When calling `git__throw`, please try to use more generic error codes so we can eventually reduce the list of error codes to something more reasonable. Feel free to add new, more generic error codes if these are going to replace several of the old ones. E.g. return GIT_EREFCORRUPTED; Can be turned into: return git__throw(GIT_EOBJCORRUPTED, "The reference is corrupted");

Carlos Martín Nieto 68a146c1 2011-04-29T11:45:42 refs: don't loose info on resolve error Typical use is git_reference_resolve(&ref, ref). Currently, if there is an error, ref will point to NULL, causing the user to lose that reference. Always update resolved_ref instead of just on finding an OID ref, storing the last valid reference in it. This change helps simplify the code for allowing root commits.

These functions try to update the reference if it's of the same type as the one it's going to be replaced by. Otherwise the old reference becomes invalid.

Vicent Marti 09e8de0f 2011-03-25T23:53:38 New external API method: `git_reference_listcb` List all the references in the repository, calling a custom callback for each one. The listed references may be filtered by type, or using a bitwise OR of several types. Use the magic value `GIT_REF_LISTALL` to obtain all references, including packed ones. The `callback` function will be called for each of the references in the repository, and will receive the name of the reference and the `payload` value passed to this method.
