d525e063	2021-05-10T23:04:59	buf: remove internal `git_buf_text` namespace The `git_buf_text` namespace is unnecessary and strange. Remove it, just keep the functions prefixed with `git_buf`.

855f2998	2021-01-05T14:45:14	blob: fix name of `GIT_BLOB_FILTER_ATTRIBUTES_FROM_HEAD` `GIT_BLOB_FILTER_ATTTRIBUTES_FROM_HEAD` is misspelled, it should be `GIT_BLOB_FILTER_ATTRIBUTES_FROM_HEAD`, and it would be if it were not for the MacBook Pro keyboard and my inattentiveness.
d9c15387	2021-01-05T14:29:58	blob: add git_blob_filter_options_init The `git_blob_filter_options_init` function should be included, to allow callers in FFI environments to let us initialize an options structure for them.
cb4bfbc9	2020-04-05T11:07:54	buffer: git_buf_sanitize should return a value `git_buf_sanitize` is called with user-input, and wants to sanity-check that input. Allow it to return a value if the input was malformed in a way that we cannot cope.

c6184f0c	2020-06-08T21:07:36	tree-wide: do not compile deprecated functions with hard deprecation When compiling libgit2 with -DDEPRECATE_HARD, we add a preprocessor definition `GIT_DEPRECATE_HARD` which causes the "git2/deprecated.h" header to be empty. As a result, no function declarations are made available to callers, but the implementations are still available to link against. This has the problem that function declarations also aren't visible to the implementations, meaning that the symbol's visibility will not be set up correctly. As a result, the resulting library may not expose those deprecated symbols at all on some platforms and thus cause linking errors. Fix the issue by conditionally compiling deprecated functions, only. While it becomes impossible to link against such a library in case one uses deprecated functions, distributors of libgit2 aren't expected to pass -DDEPRECATE_HARD anyway. Instead, users of libgit2 should manually define GIT_DEPRECATE_HARD to hide deprecated functions. Using "real" hard deprecation still makes sense in the context of CI to test we don't use deprecated symbols ourselves and in case a dependant uses libgit2 in a vendored way and knows it won't ever use any of the deprecated symbols anyway.
4334b177	2019-06-23T15:43:38	blob: use `git_object_size_t` for object size Instead of using a signed type (`off_t`) use a new `git_object_size_t` for the sizes of objects.
fba3bf79	2019-07-21T14:15:12	blob: optionally read attributes from repository When `GIT_BLOB_FILTER_ATTTRIBUTES_FROM_HEAD` is passed to `git_blob_filter`, read attributes from `gitattributes` files that are checked in to the repository at the HEAD revision. This passes the flag `GIT_FILTER_ATTRIBUTES_FROM_HEAD` to the filter functions.
a5392eae	2019-07-21T12:13:07	blob: allow blob filtering to ignore system gitattributes Introduce `GIT_BLOB_FILTER_NO_SYSTEM_ATTRIBUTES`, which tells `git_blob_filter` to ignore the system-wide attributes file, usually `/etc/gitattributes`. This simply passes the appropriate flag to the attribute loading code.
fa1a4c77	2019-07-21T11:03:01	blob: deprecate `git_blob_filtered_content` Users should now use `git_blob_filter`.
a32ab076	2019-07-21T10:56:42	blob: introduce git_blob_filter Provide a function to filter blobs that allows for more functionality than the existing `git_blob_filtered_content` function.
08f39208	2019-06-08T17:46:04	blob: add underscore to `from` functions The majority of functions are named `from_something` (with an underscore) instead of `fromsomething`. Update the blob functions for consistency with the rest of the library.
c6cac733	2019-01-20T22:40:38	blob: validate that blob sizes fit in a size_t Our blob size is a `git_off_t`, which is a signed 64 bit int. This may be erroneously negative or larger than `SIZE_MAX`. Ensure that the blob size fits into a `size_t` before casting.

9ac79ecc	2017-10-13T13:15:13	blob: implement function to parse raw data Currently, parsing objects is strictly tied to having an ODB object available. This makes it hard to parse an object when all that is available is its raw object and size. Furthermore, hacking around that limitation by directly creating an ODB structure either on stack or on heap does not really work that well due to ODB objects being reference counted and then automatically free'd when reaching a reference count of zero. In some occasions parsing raw objects without touching the ODB is actually recuired, though. One use case is for example object verification, where we want to assure that an object is valid before inserting it into the ODB or writing it into the git repository. Asa first step towards that, introduce a distinction between raw and ODB objects for blobs. Creation of ODB objects stays the same by simply using `git_blob__parse`, but a new function `git_blob__parse_raw` has been added that creates a blob from a pair of data and size. By setting a new flag inside of the blob, we can now distinguish whether it is a raw or ODB object now and treat it accordingly in several places. Note that the blob data passed in is not being copied. Because of that, callers need to make sure to keep it alive during the blob's life time. This is being used to avoid unnecessarily increasing the memory footprint when parsing largish blobs.
bbbe8441	2017-10-13T13:14:54	blob: use getters to get raw blob content and size Going forward, we will have to change how blob sizes are calculated based on whether the blob is a cahed object part of the ODB or not. In order to not have to distinguish between those two object types repeatedly when accessing the blob's data or size, encapsulate all existing direct uses of those fields by instead using `git_blob_rawcontent` and `git_blob_rawsize`.

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.
c5f3da96	2016-11-11T14:36:43	repository: use `git_repository_item_path` The recent introduction of the commondir variable of a repository requires callers to distinguish whether their files are part of the dot-git directory or the common directory shared between multpile worktrees. In order to take the burden from callers and unify knowledge on which files reside where, the `git_repository_item_path` function has been introduced which encapsulate this knowledge. Modify most existing callers of `git_repository_path` to use `git_repository_item_path` instead, thus making them implicitly aware of the common directory.

6669e3e8	2015-11-08T04:28:08	blob: remove _fromchunks() The callback mechanism makes it awkward to write data from an IO source; move to `_fromstream()` which lets the caller remain in control, in the same vein as we prefer iterators over foreach callbacks.
0a5c6028	2015-11-04T10:30:48	blob: introduce creating a blob by writing into a stream The pair of `git_blob_create_frombuffer()` and `git_blob_create_frombuffer_commit()` is meant to replace `git_blob_create_fromchunks()` by providing a way for a user to write a new blob when they want filtering or they do not know the size. This approach allows the caller to retain control over when to add data to this buffer and a more natural fit into higher-level language's own stream abstractions instead of having to handle IO wait in the callback. The in-memory buffer size of 2MB is chosen somewhat arbitrarily to be a round multiple of usual page sizes and a value where most blobs seem likely to be either going to be way below or way over that size. It's also a round number of pages. This implementation re-uses the helper we have from `_fromchunks()` so we end up writing everything to disk, but hopefully more efficiently than with a default filebuf. A later optimisation can be to avoid writing the in-memory contents to disk, with some extra complexity.
0d98af09	2015-07-11T19:03:38	blob: fail to create a blob from a dir with EDIRECTORY This also affects `git_index_add_bypath()` by providing a better error message and a specific error code when a directory is passed.
77b339f7	2015-05-12T13:06:33	odb: make the writestream's size a git_off_t Restricting files to size_t is a silly limitation. The loose backend writes to a file directly, so there is no issue in using 63 bits for the size. We still assume that the header is going to fit in 64 bytes, which does mean quite a bit smaller files due to the run-length encoding, but it's still a much larger size than you would want Git to handle.

795eaccd	2015-02-19T11:09:54	git_filter_opt_t -> git_filter_flag_t For consistency with the rest of the library, where an opt is an options structure.
d4cf1675	2015-02-19T10:05:33	buffer: introduce git_buf_attach_notowned Provide a convenience function that creates a buffer that can be provided to callers but will not be freed via `git_buf_free`, so the buffer creator maintains the allocation lifecycle of the buffer's contents.
d0f00de4	2014-05-16T11:08:19	Increase binary detection len to 8k
5269008c	2014-05-06T16:01:49	Add filter options and ALLOW_UNSAFE Diff and status do not want core.safecrlf to actually raise an error regardless of the setting, so this extends the filter API with an additional options flags parameter and adds a flag so that filters can be applied with GIT_FILTER_OPT_ALLOW_UNSAFE, indicating that unsafe filter application should be downgraded from a failure to a warning.

19853bdd	2013-12-10T13:01:34	Update git_blob_create_fromchunks callback behavr The callback to supply data chunks could return a negative value to stop creation of the blob, but we were neither using GIT_EUSER nor propagating the return value. This makes things use the new behavior of returning the negative value back to the user.
1d3a8aeb	2013-11-04T18:28:57	move mode_t to filebuf_open instead of _commit
4b11f25a	2013-09-11T16:38:33	Add ident filter This adds the ident filter (that knows how to replace $Id$) and tweaks the filter APIs and code so that git_filter_source objects actually have the updated OID of the object being filtered when it is a known value.
a9f51e43	2013-09-11T22:00:36	Merge git_buf and git_buffer This makes the git_buf struct that was used internally into an externally available structure and eliminates the git_buffer. As part of that, some of the special cases that arose with the externally used git_buffer were blended into the git_buf, such as being careful about git_buf objects that may have a NULL ptr and allowing for bufs with a valid ptr and size but zero asize as a way of referring to externally owned data.
2a7d224f	2013-09-10T16:33:32	Extend public filter api with filter lists This moves the git_filter_list into the public API so that users can create, apply, and dispose of filter lists. This allows more granular application of filters to user data outside of libgit2 internals. This also converts all the internal usage of filters to the public APIs along with a few small tweaks to make it easier to use the public git_buffer stuff alongside the internal git_buf.
85d54812	2013-08-28T16:44:04	Create public filter object and use it This creates include/sys/filter.h with a basic definition of a git_filter and then converts the internal code to use it. There are related internal objects (git_filter_list) that we will want to publish at some point, but this is a first step.
0cf77103	2013-08-26T23:17:07	Start of filter API + git_blob_filtered_content This begins the process of exposing git_filter objects to the public API. This includes: * new public type and API for `git_buffer` through which an allocated buffer can be passed to the user * new API `git_blob_filtered_content` * make the git_filter type and GIT_FILTER_TO_... constants public
376e6c9f	2013-08-15T13:48:35	odb: wrap the stream reading and writing functions This is in preparation for moving the hashing to the frontend, which requires us to handle the incoming data before passing it to the backend's stream.
8dd8aa48	2013-07-26T10:28:57	Fix some warnings
a16e4172	2013-07-25T12:27:39	Fix rename detection to use actual blob size The size data in the index may not reflect the actual size of the blob data from the ODB when content filtering comes into play. This commit fixes rename detection to use the actual blob size when calculating data signatures instead of the value from the index. Because of a misunderstanding on my part, I first converted the git_index_add_bypath API to use the post-filtered blob data size in creating the index entry. I backed that change out, but I kept the overall refactoring of that routine and the new internal git_blob__create_from_paths API because it eliminates an extra stat() call from the code that adds a file to the index. The existing tests actually cover this code path, at least when running on Windows, so at this point I'm not adding new tests to cover the changes.
114f5a6c	2013-06-10T10:10:39	Reorganize diff and add basic diff driver This is a significant reorganization of the diff code to break it into a set of more clearly distinct files and to document the new organization. Hopefully this will make the diff code easier to understand and to extend. This adds a new `git_diff_driver` object that looks of diff driver information from the attributes and the config so that things like function content in diff headers can be provided. The full driver spec is not implemented in the commit - this is focused on the reorganization of the code and putting the driver hooks in place. This also removes a few #includes from src/repository.h that were overbroad, but as a result required extra #includes in a variety of places since including src/repository.h no longer results in pulling in the whole world.
0b726701	2013-04-30T13:13:38	object: Explicitly define helper API methods for all obj types
203d5b0e	2013-04-29T18:20:58	Some cleanups Removed useless prototype and renamed object typecast functions declaration macro.
d7761102	2013-04-29T14:22:06	Standardize cast versions of git_object accessors This removes the GIT_INLINE versions of the simple git_object accessors and standardizes them with a helper macro in src/object.h to build the function bodies.
3f27127d	2013-04-16T11:51:02	Simplify object table parse functions This unifies the object parse functions into one signature that takes an odb_object.
78606263	2013-04-15T00:05:44	Add callback to git_objects_table This adds create and free callback to the git_objects_table so that more of the creation and destruction of objects can be table driven instead of using switch statements. This also makes the semantics of certain object creation functions consistent so that we can make better use of function pointers. This also fixes a theoretical error case where an object allocation fails and we end up storing NULL into the cache.
badd85a6	2013-04-10T17:10:17	Use git_odb_object_data/_size whereever possible This uses the odb object accessors so we can change the internals more easily...

83cc70d9	2013-04-19T12:48:33	Move odb_backend implementors stuff into git2/sys This moves some of the odb_backend stuff that is related to the internals of an odb_backend implementation into include/git2/sys. Some of the stuff related to streaming I left in include/git2 because it seemed like it would be reasonably needed by a normal user who wanted to stream objects into and out of the ODB. Also, I added APIs for traversing the list of backends so that some of the tests would not need to access ODB internals.
3658e81e	2013-03-25T14:20:07	Move crlf conversion into buf_text This adds crlf/lf conversion functions into buf_text with more efficient implementations that bypass the high level buffer functions. They attempt to minimize the number of reallocations done and they directly write the buffer data as needed if they know that there is enough memory allocated to memcpy data. Tests are added for these new functions. The crlf.c code is updated to use the new functions. Removed the include of buf_text.h from filter.h and just include it more narrowly in the places that need it.
9733e80c	2013-03-22T10:44:45	Add has_cr_in_index check to CRLF filter This adds a check to the drop_crlf filter path to check it the file in the index already has a CR in it, in which case this will not drop the CRs from the workdir file contents. This uncovered a "bug" in `git_blob_create_fromworkdir` where the full path to the file was passed to look up the attributes instead of the relative path from the working directory root. This meant that the check in the index for a pre-existing entry of the same name was failing.
359fc2d2	2013-01-08T17:07:25	update copyrights
f2b7f7a6	2013-01-07T15:44:22	Share git_diff_blobs/git_diff_blob_to_buffer code This moves the implementation of these two APIs into common code that will be shared between the two. Also, this adds tests for the `git_diff_blob_to_buffer` API. Lastly, this adds some extra `const` to a few places that can use it.

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.
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.
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.
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.

44b1ff4c	2012-02-27T04:31:05	filter: Apply filters before writing a file to the ODB Initial implementation. The relevant code is in `blob.c`: the blob write function has been split into smaller functions. - Directly write a file to the ODB in streaming mode - Directly write a symlink to the ODB in direct mode - Apply a filter, and write a file to the ODB in direct mode When trying to write a file, we first call `git_filter__load_for_file`, which populates a filters array with the required filters based on the filename. If no filters are resolved to the filename, we can write to the ODB in streaming mode straight from disk. Otherwise, we load the whole file in memory and use double-buffering to apply the filter chain. We finish by writing the file as a whole to the ODB.

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.
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.
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.

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.

b74c867a	2011-06-07T11:11:09	blob: Stat path inside git_blob_create_fromfile 00582bc introduced a change that required the caller of git_blob_create_fromfile() to pass a struct stat with the stat information for the file. Several developers pointed out that this would make life hard for the bindings developers as struct stat isn't widely supported by other languages. Make git_blob_create_fromfile() stat the path itself, eliminating the need for the file to be stat'ed by the caller. This makes index_init_entry() more costly as the file will be stat'ed twice but makes life easier for everyone else.
4d7905c5	2011-05-25T16:04:29	blob: Require stat information for git_blob_create_fromfile() In order to be able to write symlinks with git_blob_create_fromfile(), we need to check whether the file to be written is a symbolic link or not. Since the calling function of git_blob_create_fromfile() is likely to have stated the file before calling, we make it pass the stat. The reason for this is that writing symbolic link blobs is significantly different from writing ordinary files - we do not want to open the link destination but instead want to write the link itself, regardless of whether it exists or not. Previously, index_init_entry() used to error out if the file to be added was a symlink that pointed to a nonexistent file. Fix this behaviour to add the file regardless of whether it exists. This mimics git.git's behaviour.

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>
6b2a1941	2011-03-12T23:09:16	Fix the retarded object interdependency system It's no longer retarded. All object interdependencies are stored as OIDs instead of actual objects. This should be hundreds of times faster, specially on big repositories. Heck, who knows, maye it doesn't even segfault -- wouldn't that be awesome? What has changed on the API? `git_commit_parent`, `git_commit_tree`, `git_tag_target` now return their values through a pointer-to-pointer, and have an error code. `git_commit_set_tree` and `git_tag_set_target` now return an error code and may fail. `git_repository_free__no_gc` has been deprecated because it's stupid. Since there are no longer any interdependencies between objects, we don't need internal reference counting, and GC never fails or double-free's pointers. `git_object_close` now does a very sane thing: marks an object as unused. Closed objects will be eventually free'd from the object cache based on LRU. Please use `git_object_close` from the garbage collector `destroy` method on your bindings. It's 100% safe. `git_repository_gc` is a new method that forces a garbage collector pass through the repo, to free as many LRU objects as possible. This is useful if we are running out of memory.

tree-wide: do not compile deprecated functions with hard deprecation When compiling libgit2 with -DDEPRECATE_HARD, we add a preprocessor definition `GIT_DEPRECATE_HARD` which causes the "git2/deprecated.h" header to be empty. As a result, no function declarations are made available to callers, but the implementations are still available to link against. This has the problem that function declarations also aren't visible to the implementations, meaning that the symbol's visibility will not be set up correctly. As a result, the resulting library may not expose those deprecated symbols at all on some platforms and thus cause linking errors. Fix the issue by conditionally compiling deprecated functions, only. While it becomes impossible to link against such a library in case one uses deprecated functions, distributors of libgit2 aren't expected to pass -DDEPRECATE_HARD anyway. Instead, users of libgit2 should manually define GIT_DEPRECATE_HARD to hide deprecated functions. Using "real" hard deprecation still makes sense in the context of CI to test we don't use deprecated symbols ourselves and in case a dependant uses libgit2 in a vendored way and knows it won't ever use any of the deprecated symbols anyway.

blob: implement function to parse raw data Currently, parsing objects is strictly tied to having an ODB object available. This makes it hard to parse an object when all that is available is its raw object and size. Furthermore, hacking around that limitation by directly creating an ODB structure either on stack or on heap does not really work that well due to ODB objects being reference counted and then automatically free'd when reaching a reference count of zero. In some occasions parsing raw objects without touching the ODB is actually recuired, though. One use case is for example object verification, where we want to assure that an object is valid before inserting it into the ODB or writing it into the git repository. Asa first step towards that, introduce a distinction between raw and ODB objects for blobs. Creation of ODB objects stays the same by simply using `git_blob__parse`, but a new function `git_blob__parse_raw` has been added that creates a blob from a pair of data and size. By setting a new flag inside of the blob, we can now distinguish whether it is a raw or ODB object now and treat it accordingly in several places. Note that the blob data passed in is not being copied. Because of that, callers need to make sure to keep it alive during the blob's life time. This is being used to avoid unnecessarily increasing the memory footprint when parsing largish blobs.

blob: use getters to get raw blob content and size Going forward, we will have to change how blob sizes are calculated based on whether the blob is a cahed object part of the ODB or not. In order to not have to distinguish between those two object types repeatedly when accessing the blob's data or size, encapsulate all existing direct uses of those fields by instead using `git_blob_rawcontent` and `git_blob_rawsize`.

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.

repository: use `git_repository_item_path` The recent introduction of the commondir variable of a repository requires callers to distinguish whether their files are part of the dot-git directory or the common directory shared between multpile worktrees. In order to take the burden from callers and unify knowledge on which files reside where, the `git_repository_item_path` function has been introduced which encapsulate this knowledge. Modify most existing callers of `git_repository_path` to use `git_repository_item_path` instead, thus making them implicitly aware of the common directory.

blob: remove _fromchunks() The callback mechanism makes it awkward to write data from an IO source; move to `_fromstream()` which lets the caller remain in control, in the same vein as we prefer iterators over foreach callbacks.

blob: introduce creating a blob by writing into a stream The pair of `git_blob_create_frombuffer()` and `git_blob_create_frombuffer_commit()` is meant to replace `git_blob_create_fromchunks()` by providing a way for a user to write a new blob when they want filtering or they do not know the size. This approach allows the caller to retain control over when to add data to this buffer and a more natural fit into higher-level language's own stream abstractions instead of having to handle IO wait in the callback. The in-memory buffer size of 2MB is chosen somewhat arbitrarily to be a round multiple of usual page sizes and a value where most blobs seem likely to be either going to be way below or way over that size. It's also a round number of pages. This implementation re-uses the helper we have from `_fromchunks()` so we end up writing everything to disk, but hopefully more efficiently than with a default filebuf. A later optimisation can be to avoid writing the in-memory contents to disk, with some extra complexity.

odb: make the writestream's size a git_off_t Restricting files to size_t is a silly limitation. The loose backend writes to a file directly, so there is no issue in using 63 bits for the size. We still assume that the header is going to fit in 64 bytes, which does mean quite a bit smaller files due to the run-length encoding, but it's still a much larger size than you would want Git to handle.

Merge git_buf and git_buffer This makes the git_buf struct that was used internally into an externally available structure and eliminates the git_buffer. As part of that, some of the special cases that arose with the externally used git_buffer were blended into the git_buf, such as being careful about git_buf objects that may have a NULL ptr and allowing for bufs with a valid ptr and size but zero asize as a way of referring to externally owned data.

Fix rename detection to use actual blob size The size data in the index may not reflect the actual size of the blob data from the ODB when content filtering comes into play. This commit fixes rename detection to use the actual blob size when calculating data signatures instead of the value from the index. Because of a misunderstanding on my part, I first converted the git_index_add_bypath API to use the post-filtered blob data size in creating the index entry. I backed that change out, but I kept the overall refactoring of that routine and the new internal git_blob__create_from_paths API because it eliminates an extra stat() call from the code that adds a file to the index. The existing tests actually cover this code path, at least when running on Windows, so at this point I'm not adding new tests to cover the changes.

Reorganize diff and add basic diff driver This is a significant reorganization of the diff code to break it into a set of more clearly distinct files and to document the new organization. Hopefully this will make the diff code easier to understand and to extend. This adds a new `git_diff_driver` object that looks of diff driver information from the attributes and the config so that things like function content in diff headers can be provided. The full driver spec is not implemented in the commit - this is focused on the reorganization of the code and putting the driver hooks in place. This also removes a few #includes from src/repository.h that were overbroad, but as a result required extra #includes in a variety of places since including src/repository.h no longer results in pulling in the whole world.

Tests are added for these new functions. The crlf.c code is updated to use the new functions. Removed the include of buf_text.h from filter.h and just include it more narrowly in the places that need it.

Add has_cr_in_index check to CRLF filter This adds a check to the drop_crlf filter path to check it the file in the index already has a CR in it, in which case this will not drop the CRs from the workdir file contents. This uncovered a "bug" in `git_blob_create_fromworkdir` where the full path to the file was passed to look up the attributes instead of the relative path from the working directory root. This meant that the check in the index for a pre-existing entry of the same name was failing.

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.

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.

filter: Apply filters before writing a file to the ODB Initial implementation. The relevant code is in `blob.c`: the blob write function has been split into smaller functions. - Directly write a file to the ODB in streaming mode - Directly write a symlink to the ODB in direct mode - Apply a filter, and write a file to the ODB in direct mode When trying to write a file, we first call `git_filter__load_for_file`, which populates a filters array with the required filters based on the filename. If no filters are resolved to the filename, we can write to the ODB in streaming mode straight from disk. Otherwise, we load the whole file in memory and use double-buffering to apply the filter chain. We finish by writing the file as a whole to the ODB.

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.

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.

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.

blob: Stat path inside git_blob_create_fromfile 00582bc introduced a change that required the caller of git_blob_create_fromfile() to pass a struct stat with the stat information for the file. Several developers pointed out that this would make life hard for the bindings developers as struct stat isn't widely supported by other languages. Make git_blob_create_fromfile() stat the path itself, eliminating the need for the file to be stat'ed by the caller. This makes index_init_entry() more costly as the file will be stat'ed twice but makes life easier for everyone else.

2011-05-25T16:04:29

blob: Require stat information for git_blob_create_fromfile() In order to be able to write symlinks with git_blob_create_fromfile(), we need to check whether the file to be written is a symbolic link or not. Since the calling function of git_blob_create_fromfile() is likely to have stated the file before calling, we make it pass the stat. The reason for this is that writing symbolic link blobs is significantly different from writing ordinary files - we do not want to open the link destination but instead want to write the link itself, regardless of whether it exists or not. Previously, index_init_entry() used to error out if the file to be added was a symlink that pointed to a nonexistent file. Fix this behaviour to add the file regardless of whether it exists. This mimics git.git's behaviour.

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>

Fix the retarded object interdependency system It's no longer retarded. All object interdependencies are stored as OIDs instead of actual objects. This should be hundreds of times faster, specially on big repositories. Heck, who knows, maye it doesn't even segfault -- wouldn't that be awesome? What has changed on the API? `git_commit_parent`, `git_commit_tree`, `git_tag_target` now return their values through a pointer-to-pointer, and have an error code. `git_commit_set_tree` and `git_tag_set_target` now return an error code and may fail. `git_repository_free__no_gc` has been deprecated because it's stupid. Since there are no longer any interdependencies between objects, we don't need internal reference counting, and GC never fails or double-free's pointers. `git_object_close` now does a very sane thing: marks an object as unused. Closed objects will be eventually free'd from the object cache based on LRU. Please use `git_object_close` from the garbage collector `destroy` method on your bindings. It's 100% safe. `git_repository_gc` is a new method that forces a garbage collector pass through the repo, to free as many LRU objects as possible. This is useful if we are running out of memory.
