Edward Thomson f0e693b1 2021-09-07T17:53:49 str: introduce `git_str` for internal, `git_buf` is external libgit2 has two distinct requirements that were previously solved by `git_buf`. We require: 1. A general purpose string class that provides a number of utility APIs for manipulating data (eg, concatenating, truncating, etc). 2. A structure that we can use to return strings to callers that they can take ownership of. By using a single class (`git_buf`) for both of these purposes, we have confused the API to the point that refactorings are difficult and reasoning about correctness is also difficult. Move the utility class `git_buf` to be called `git_str`: this represents its general purpose, as an internal string buffer class. The name also is an homage to Junio Hamano ("gitstr"). The public API remains `git_buf`, and has a much smaller footprint. It is generally only used as an "out" param with strict requirements that follow the documentation. (Exceptions exist for some legacy APIs to avoid breaking callers unnecessarily.) Utility functions exist to convert a user-specified `git_buf` to a `git_str` so that we can call internal functions, then converting it back again.

Edward Thomson 46508fe6 2021-09-26T11:28:47 attr_file: don't take the `repo` as an arg The `repo` argument is now unnecessary. Remove it.
Edward Thomson 091bd738 2021-09-24T17:00:43 attr: ensure lookups are on repo-relative paths Attribute lookups are done on paths relative to the repository. Fail if erroneously presented with an absolute path.
Edward Thomson 90656858 2021-09-21T11:28:39 filter: use a `git_oid` in filter options, not a pointer Using a `git_oid *` in filter options was a mistake; it is a deviation from our typical pattern, and callers in some languages that GC may need very special treatment in order to pass both an options structure and a pointer outside of it.
Edward Thomson 0bd547a8 2021-07-22T15:29:46 attr: introduce GIT_ATTR_CHECK_INCLUDE_COMMIT Introduce `GIT_ATTR_CHECK_INCLUDE_COMMIT`, which like 4fd5748 allows attribute information to be read from files in the repository. 4fd5748 always reads the information from HEAD, while `GIT_ATTR_CHECK_INCLUDE_COMMIT` allows users to provide the commit to read the attributes from.
Edward Thomson 3779a047 2021-05-27T18:47:22 attr: introduce `git_attr_options` for extended queries Allow more advanced attribute queries using a `git_attr_options`, and extended functions to use it. Presently there is no additional configuration in a `git_attr_options` beyond the flags, but this is for future growth.
Edward Thomson 1cd863fd 2021-05-24T13:44:45 attr: include the filename in the attr source The attribute source object is now the type and the path.
Edward Thomson 5ee50488 2021-05-22T18:47:03 attr: rename internal attr file source enum The enum `git_attr_file_source` is better suffixed with a `_t` since it's a type-of source. Similarly, its members should have a matching name.
Edward Thomson 1016ad4f 2021-04-15T01:31:12 path: don't join paths in git_path_find_dir Let `git_path_find_dir` simply take a `git_buf` that contains a directory or a file, instead of trying to both join a path AND then deal with prettifying it or its basename. This allows consumers to join paths themselves (and apply any necessary rules - like fitting within MAX_PATH).
Edward Thomson 9fb755d5 2021-04-04T19:59:57 attr: validate workdir paths for attribute files We should allow attribute files - inside working directories - to have names longer than MAX_PATH when core.longpaths is set. `git_attr_path__init` takes a repository to validate the path with.
Edward Thomson 7b2f94bf 2020-04-05T10:04:52 attr: use GIT_ASSERT
Edward Thomson 4fd5748c 2019-07-21T14:11:03 attr: optionally read attributes from repository When `GIT_ATTR_CHECK_INCLUDE_HEAD` is specified, read `gitattribute` files that are checked into the repository at the HEAD revision.
Patrick Steinhardt f8346905 2019-07-12T09:03:33 attr_file: ignore macros defined in subdirectories Right now, we are unconditionally applying all macros found in a gitatttributes file. But quoting gitattributes(5): Custom macro attributes can be defined only in top-level gitattributes files ($GIT_DIR/info/attributes, the .gitattributes file at the top level of the working tree, or the global or system-wide gitattributes files), not in .gitattributes files in working tree subdirectories. The built-in macro attribute "binary" is equivalent to: So gitattribute files in subdirectories of the working tree may explicitly _not_ contain macro definitions, but we do not currently enforce this limitation. This patch introduces a new parameter to the gitattributes parser that tells whether macros are allowed in the current file or not. If set to `false`, we will still parse macros, but silently ignore them instead of adding them to the list of defined macros. Update all callers to correctly determine whether the to-be-parsed file may contain macros or not. Most importantly, when walking up the directory hierarchy, we will only set it to `true` once it reaches the root directory of the repo itself. Add a test that verifies that we are indeed not applying macros from subdirectories. Previous to these changes, the test would've failed.
Sven Strickroth 18a6d9f3 2019-06-29T16:19:08 attr: Don't fail in attr_setup if there exists a system attributes file Regression introduced in commit 5452e49fce21f726bec19519da7f012e3f19e736 on PR #4967. Signed-off-by: Sven Strickroth <email@cs-ware.de>
Patrick Steinhardt 82c7a9bc 2019-06-26T14:49:24 attr: fix attribute lookup if repo has no common directory If creating a repository without a common directory (e.g. by using `git_repository_new`), then `git_repository_item_path` will return `GIT_ENOTFOUND` for every file that's usually located in this directory. While we do not care for this case when looking up the "info/attributes" file, we fail to properly ignore these errors when setting up or collecting attributes files. Thus, the gitattributes lookup is broken and will only ever return `GIT_ENOTFOUND`. Fix this issue by properly ignoring `GIT_ENOTFOUND` returned by `git_repository_item_path`.
Patrick Steinhardt 5452e49f 2019-06-26T14:49:17 attr: refactor setup to match current coding style The code in the `attr_setup` function is not really matching our current coding style. Besides alignment issues, it's also hard to see what functions calls depend on one another because they're split up over multiple conditional statements. Fix these issues by grouping together dependent function calls and adjusting the alignment.
Edward Thomson 91a300b7 2019-06-16T00:46:30 attr: rename constants and macros for consistency Our enumeration values are not generally suffixed with `T`. Further, our enumeration names are generally more descriptive.
Patrick Steinhardt 03555830 2019-01-23T10:44:33 strmap: introduce high-level setter for key/value pairs Currently, one would use the function `git_strmap_insert` to insert key/value pairs into a map. This function has historically been a macro, which is why its syntax is kind of weird: instead of returning an error code directly, it instead has to be passed a pointer to where the return value shall be stored. This does not match libgit2's common idiom of directly returning error codes. Introduce a new function `git_strmap_set`, which takes as parameters the map, key and value and directly returns an error code. Convert all callers of `git_strmap_insert` to make use of it.
Patrick Steinhardt 351eeff3 2019-01-23T10:42:46 maps: use uniform lifecycle management functions Currently, the lifecycle functions for maps (allocation, deallocation, resize) are not named in a uniform way and do not have a uniform function signature. Rename the functions to fix that, and stick to libgit2's naming scheme of saying `git_foo_new`. This results in the following new interface for allocation: - `int git_<t>map_new(git_<t>map **out)` to allocate a new map, returning an error code if we ran out of memory - `void git_<t>map_free(git_<t>map *map)` to free a map - `void git_<t>map_clear(git<t>map *map)` to remove all entries from a map This commit also fixes all existing callers.
Edward Thomson f673e232 2018-12-27T13:47:34 git_error: use new names in internal APIs and usage Move to the `git_error` name in the internal API for error-related functions.
Patrick Steinhardt ecf4f33a 2018-02-08T11:14:48 Convert usage of `git_buf_free` to new `git_buf_dispose`
Patrick Steinhardt e28e17e6 2018-02-01T10:36:33 attr: avoid stat'ting files for bare repositories Depending on whether the path we want to look up an attribute for is a file or a directory, the fnmatch function will be called with different flags. Because of this, we have to first stat(3) the path to determine whether it is a file or directory in `git_attr_path__init`. This is wasteful though in bare repositories, where we can already be assured that the path will never exist at all due to there being no worktree. In this case, we will execute an unnecessary syscall, which might be noticeable on networked file systems. What happens right now is that we always pass the `GIT_DIR_FLAG_UNKOWN` flag to `git_attr_path__init`, which causes it to `stat` the file itself to determine its type. As it is calling `git_path_isdir` on the path, which will always return `false` in case the path does not exist, we end up with the path always being treated as a file in case of a bare repository. As such, we can just check the bare-repository case in all callers and then pass in `GIT_DIR_FLAG_FALSE` ourselves, avoiding the need to `stat`. While this may not always be correct, it at least is no different from our current behavior.
Patrick Steinhardt 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.
Patrick Steinhardt 2480d0eb 2017-06-30T13:34:05 Add missing license headers Some implementation files were missing the license headers. This commit adds them.

Patrick Steinhardt 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.
Edward Thomson 30e629a0 2015-05-11T17:34:14 attr: always return errors
J Wyman 4c09e19a 2015-03-30T14:07:44 Improvements to ignore performance on Windows. Minimizing the number directory and file opens, minimizes the amount of IO thus reducing the overall cost of performing ignore operations.
Edward Thomson 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.
Stefan Widgren c8e02b87 2015-02-15T21:07:05 Remove extra semicolon outside of a function Without this change, compiling with gcc and pedantic generates warning: ISO C does not allow extra ‘;’ outside of a function.

Edward Thomson d4b1b767 2015-02-03T00:03:49 checkout: cache system attributes file location
Edward Thomson 9f779aac 2015-01-29T14:40:55 attrcache: don't re-read attrs during checkout During checkout, assume that the .gitattributes files aren't modified during the checkout. Instead, create an "attribute session" during checkout. Assume that attribute data read in the same checkout "session" hasn't been modified since the checkout started. (But allow subsequent checkouts to invalidate the cache.) Further, cache nonexistent git_attr_file data even when .gitattributes files are not found to prevent re-scanning for nonexistent files.

Russell Belfer 1fbeb2f0 2014-09-15T21:59:23 Fix attribute lookup in index for bare repos When using a bare repo with an index, libgit2 attempts to read files from the index. It caches those files based on the path to the file, specifically the path to the directory that contains the file. If there is no working directory, we use `git_path_dirname_r` to get the path to the containing directory. However, for the `.gitattributes` file in the root of the repository, this ends up normalizing the containing path to `"."` instead of the empty string and the lookup the `.gitattributes` data fails. This adds a test of attribute lookups on bare repos and also fixes the problem by simply rewriting `"."` to be `""`.
Russell Belfer ac16bd0a 2014-04-18T15:45:59 Minor fixes Only apply LEADING_DIR pattern munging to patterns in ignore and attribute files, not to pathspecs used to select files to operate on. Also, allow internal macro definitions to be evaluated before loading all external ones (important so that external ones can make use of internal `binary` definition).
Russell Belfer e3a2a04c 2014-04-18T14:29:58 Preload attribute files that may contain macros There was a latent bug where files that use macro definitions could be parsed before the macro definitions were loaded. Because of attribute file caching, preloading files that are going to be used doesn't add a significant amount of overhead, so let's always preload any files that could contain macros before we assemble the actual vector of files to scan for attributes.
Russell Belfer 823c0e9c 2014-04-17T11:53:13 Fix broken logic for attr cache invalidation The checks to see if files were out of date in the attibute cache was wrong because the cache-breaker data wasn't getting stored correctly. Additionally, when the cache-breaker triggered, the old file data was being leaked.
Russell Belfer 2e9d813b 2014-04-11T12:12:47 Fix tests with new attr cache code
Russell Belfer 7d490872 2014-04-10T22:31:01 Attribute file cache refactor This is a big refactoring of the attribute file cache to be a bit simpler which in turn makes it easier to enforce a lock around any updates to the cache so that it can be used in a threaded env. Tons of changes to the attributes and ignores code.
Russell Belfer 40ed4990 2014-02-11T14:45:37 Add diff threading tests and attr file cache locks This adds a basic test of doing simultaneous diffs on multiple threads and adds basic locking for the attr file cache because that was the immediate problem that arose from these tests.

Russell Belfer 26c1cb91 2013-12-09T09:44:03 One more rename/cleanup for callback err functions
Russell Belfer c7b3e1b3 2013-12-06T15:42:20 Some callback error check style cleanups I find this easier to read...
Russell Belfer 25e0b157 2013-12-06T15:07:57 Remove converting user error to GIT_EUSER This changes the behavior of callbacks so that the callback error code is not converted into GIT_EUSER and instead we propagate the return value through to the caller. Instead of using the giterr_capture and giterr_restore functions, we now rely on all functions to pass back the return value from a callback. To avoid having a return value with no error message, the user can call the public giterr_set_str or some such function to set an error message. There is a new helper 'giterr_set_callback' that functions can invoke after making a callback which ensures that some error message was set in case the callback did not set one. In places where the sign of the callback return value is meaningful (e.g. positive to skip, negative to abort), only the negative values are returned back to the caller, obviously, since the other values allow for continuing the loop. The hardest parts of this were in the checkout code where positive return values were overloaded as meaningful values for checkout. I fixed this by adding an output parameter to many of the internal checkout functions and removing the overload. This added some code, but it is probably a better implementation. There is some funkiness in the network code where user provided callbacks could be returning a positive or a negative value and we want to rely on that to cancel the loop. There are still a couple places where an user error might get turned into GIT_EUSER there, I think, though none exercised by the tests.
Russell Belfer dab89f9b 2013-12-04T21:22:57 Further EUSER and error propagation fixes This continues auditing all the places where GIT_EUSER is being returned and making sure to clear any existing error using the new giterr_user_cancel helper. As a result, places that relied on intercepting GIT_EUSER but having the old error preserved also needed to be cleaned up to correctly stash and then retrieve the actual error. Additionally, as I encountered places where error codes were not being propagated correctly, I tried to fix them up. A number of those fixes are included in the this commit as well.
Russell Belfer 96869a4e 2013-12-03T16:45:39 Improve GIT_EUSER handling This adds giterr_user_cancel to return GIT_EUSER and clear any error message that is sitting around. As a result of using that in places, we need to be more thorough with capturing errors that happen inside a callback when used internally. To help with that, this also adds giterr_capture and giterr_restore so that when we internally use a foreach-type function that clears errors and converts them to GIT_EUSER, it is easier to restore not just the return value, but the actual error message text.
Russell Belfer 9f77b3f6 2013-11-25T14:21:34 Add config read fns with controlled error behavior This adds `git_config__lookup_entry` which will look up a key in a config and return either the entry or NULL if the key was not present. Optionally, it can either suppress all errors or can return them (although not finding the key is not an error for this function). Unlike other accessors, this does not normalize the config key string, so it must only be used when the key is known to be in normalized form (i.e. all lower-case before the first dot and after the last dot, with no invalid characters). This also adds three high-level helper functions to look up config values with no errors and a fallback value. The three functions are for string, bool, and int values, and will resort to the fallback value for any error that arises. They are: * `git_config__get_string_force` * `git_config__get_bool_force` * `git_config__get_int_force` None of them normalize the config `key` either, so they can only be used for internal cases where the key is known to be in normal format.
Cheng Zhao 157cef10 2013-10-28T12:57:15 The "common.h" should be included before "config.h". When building libgit2 for ia32 architecture on a x64 machine, including "config.h" without a "common.h" would result the following error: C:\Program Files\Microsoft SDKs\Windows\v7.1\include\winbase.h(2288): error C2373: 'InterlockedIncrement' : redefinition; different type modifiers [C:\cygwin\home\zcbenz\codes\git-utils\build\libgit2.vcxproj] C:\Program Files\Microsoft SDKs\Windows\v7.1\include\winbase.h(2295): error C2373: 'InterlockedDecrement' : redefinition; different type modifiers [C:\cygwin\home\zcbenz\codes\git-utils\build\libgit2.vcxproj] C:\Program Files\Microsoft SDKs\Windows\v7.1\include\winbase.h(2303): error C2373: 'InterlockedExchange' : redefinition; different type modifiers [C:\cygwin\home\zcbenz\codes\git-utils\build\libgit2.vcxproj] C:\Program Files\Microsoft SDKs\Windows\v7.1\include\winbase.h(2314): error C2373: 'InterlockedExchangeAdd' : redefinition; different type modifiers [C:\cygwin\home\zcbenz\codes\git-utils\build\libgit2.vcxproj]
Russell Belfer 974774c7 2013-09-09T16:57:34 Add attributes to filters and fix registry The filter registry as implemented was too primitive to actually work once multiple filters were coming into play. This expands the implementation of the registry to handle multiple prioritized filters correctly. Additionally, this adds an "attributes" field to a filter that makes it really really easy to implement filters that are based on one or more attribute values. The lookup and even simple value checking can all happen automatically without custom filter code. Lastly, with the registry improvements, this fills out the filter lifecycle callbacks, with initialize and shutdown callbacks that will be called before the filter is first used and after it is last invoked. This allows for system-wide initialization and cleanup by the filter.
Russell Belfer 7a5ee3dc 2013-05-24T11:09:04 Add ~ expansion to global attributes and excludes This adds ~/ prefix expansion for the value of core.attributesfile and core.excludesfile, plus it fixes the fact that the attributes cache was holding on to the string data from the config for a long time (instead of making its own strdup) which could have caused a problem if the config was refreshed. Adds a test for the new expansion capability.

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.
Russell Belfer 37d91686 2013-02-22T12:21:54 Do not fail if .gitignore is directory This is designed to fix libgit2sharp #350 where if .gitignore is a directory we abort all operations that process ignores instead of just skipping it as core git does. Also added test that fails without this change and passes with it.

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 f335ecd6 2012-08-30T14:24:16 Diff iterators This refactors the diff output code so that an iterator object can be used to traverse and generate the diffs, instead of just the `foreach()` style with callbacks. The code has been rearranged so that the two styles can still share most functions. This also replaces `GIT_REVWALKOVER` with `GIT_ITEROVER` and uses that as a common error code for marking the end of iteration when using a iterator style of object.

Russell Belfer 5dca2010 2012-08-03T17:08:01 Update iterators for consistency across library This updates all the `foreach()` type functions across the library that take callbacks from the user to have a consistent behavior. The rules are: * A callback terminates the loop by returning any non-zero value * Once the callback returns non-zero, it will not be called again (i.e. the loop stops all iteration regardless of state) * If the callback returns non-zero, the parent fn returns GIT_EUSER * Although the parent returns GIT_EUSER, no error will be set in the library and `giterr_last()` will return NULL if called. This commit makes those changes across the library and adds tests for most of the iteration APIs to make sure that they follow the above rules.

Vicent Marti 0c9eacf3 2012-08-02T01:15:24 attr: Do not export variables externally Fixes #824 Exporting variables in a dynamic library is a PITA. Let's keep these values internally and wrap them through a helper method. This doesn't break the external API. @arrbee, aren't you glad I turned the `GIT_ATTR_` macros into function macros? :sparkles:

Russell Belfer 2a99df69 2012-05-24T17:14:56 Fix bugs for status with spaces and reloaded attrs This fixes two bugs: * Issue #728 where git_status_file was not working for files that contain spaces. This was caused by reusing the "fnmatch" parsing code from ignore and attribute files to interpret the "pathspec" that constrained the files to apply the status to. In that code, unescaped whitespace was considered terminal to the pattern, so a file with internal whitespace was excluded from the matched files. The fix was to add a mode to that code that allows spaces and tabs inside patterns. This mode only comes into play when parsing in-memory strings. * The other issue was undetected, but it was in the recently added code to reload gitattributes / gitignores when they were changed on disk. That code was not clearing out the old values from the cached file content before reparsing which meant that newly added patterns would be read in, but deleted patterns would not be removed. The fix was to clear the vector of patterns in a cached file before reparsing the file.

Russell Belfer dc13f1f7 2012-05-10T11:08:59 Add cache busting to attribute cache This makes the git attributes and git ignores cache check stat information before using the file contents from the cache. For cached files from the index, it checks the SHA of the file instead. This should reduce the need to ever call `git_attr_cache_flush()` in most situations. This commit also fixes the `git_status_should_ignore` API to use the libgit2 standard parameter ordering.
Russell Belfer cba285d3 2012-05-07T13:30:27 Fix directory finding for attrs The fix to support attrs on bare repos went a little too far in trying to avoid using the working directory and ended up not processing the input path quite correctly.

Russell Belfer f917481e 2012-05-03T16:37:25 Support reading attributes from index Depending on the operation, we need to consider gitattributes in both the work dir and the index. This adds a parameter to all of the gitattributes related functions that allows user control of attribute reading behavior (i.e. prefer workdir, prefer index, only use index). This fix also covers allowing us to check attributes (and hence do diff and status) on bare repositories. This was a somewhat larger change that I hoped because it had to change the cache key used for gitattributes files.
Russell Belfer d58336dd 2012-04-26T10:51:45 Fix leading slash behavior in attrs/ignores We were not following the git behavior for leading slashes in path names when matching git ignores and git attribute file patterns. This should fix issue #638.
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 19fa2bc1 2012-04-17T15:12:50 Convert attrs and diffs to use string pools This converts the git attr related code (including ignores) and the git diff related code (and implicitly the status code) to use `git_pools` for storing strings. This reduces the number of small blocks allocated dramatically.
Russell Belfer 7784bcbb 2012-04-11T11:52:59 Refactor git_repository_open with new options Add a new command `git_repository_open_ext` with extended options that control how searching for a repository will be done. The existing `git_repository_open` and `git_repository_discover` are reimplemented on top of it. We may want to change the default behavior of `git_repository_open` but this commit does not do that. Improve support for "gitdir" files where the work dir is separate from the repo and support for the "separate-git-dir" config. Also, add support for opening repos created with `git-new-workdir` script (although I have only confirmed that they can be opened, not that all functions work correctly). There are also a few minor changes that came up: - Fix `git_path_prettify` to allow in-place prettifying. - Fix `git_path_root` to support backslashes on Win32. This fix should help many repo open/discover scenarios - it is the one function called when opening before prettifying the path. - Tweak `git_config_get_string` to set the "out" pointer to NULL if the config value is not found. Allows some other cleanup. - Fix a couple places that should have been calling `git_repository_config__weakptr` and were not. - Fix `cl_git_sandbox_init` clar helper to support bare repos.
Russell Belfer 95dfb031 2012-03-30T14:40:50 Improve config handling for diff,submodules,attrs This adds support for a bunch of core.* settings that affect diff and status, plus fixes up some incorrect implementations of those settings from before. Also, this cleans up the handling of config settings in the new submodules code and in the old attrs/ignore code.
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 ab43ad2f 2012-03-14T11:07:14 Convert attr and other files to new errors This continues to add other files to the new error handling style. I think the only real concerns here are that there are a couple of error return cases that I have converted to asserts, but I think that it was the correct thing to do given the new error style.

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.
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 e8c96ed2 2012-02-01T12:30:35 Add unit tests for recent bug fixes Add unit tests to confirm ignore directory pattern matches and to confirm that ignore and attribute files are loaded properly into the attribute file cache.
