9d85f007	2013-08-24T17:39:15	fix tests on FreeBSD 238b761 introduced a test for posix behaviour, but on FreeBSD some of the structs and constants used aren't defined in <arpa/inet.h>. Include the appropriate headers to get the tests working again on FreeBSD.
972bb689	2013-08-22T14:10:56	Add SRWLock implementation of rwlocks for Win32
8d9a85d4	2013-08-22T11:40:53	Convert sortedcache to use rwlock This is the first use we have of pthread_rwlock_t in libgit2. Hopefully it won't cause any serious portability problems.
a4977169	2013-08-21T14:09:38	Add sortedcache APIs to lookup index and remove This adds two other APIs that I need to the sortedcache type.
0b7cdc02	2013-08-20T15:18:48	Add sorted cache data type This adds a convenient new data type for caching the contents of file in memory when each item in that file corresponds to a name and you need to both be able to lookup items by name and iterate over them in some sorted order. The new data type has locks in place to manage usage in a threaded environment.
c0b01b75	2013-08-19T18:46:26	Skip UTF-8 BOM in binary detection When a git_buf contains a UTF-8 BOM, the three bytes comprising that BOM are treated as unprintable characters. For a small git_buf, the three BOM characters overwhelm the printable characters. This is problematic when trying to check out a small file as the CR/LF filtering will not apply.
238b7614	2013-08-16T13:31:24	Fix p_inet_pton on windows p_inet_pton on Windows should set errno properly for callers. Rewrite p_inet_pton to handle error cases correctly and add test cases to exercise this function.
d730d3f4	2013-07-31T16:40:42	Major rename detection changes After doing further profiling, I found that a lot of time was being spent attempting to insert hashes into the file hash signature when using the rolling hash because the rolling hash approach generates a hash per byte of the file instead of one per run/line of data. To optimize this, I decided to convert back to a run-based file signature algorithm which would be more like core Git. After changing this, a number of the existing tests started to fail. In some cases, this appears to have been because the test was coded to be too specific to the particular results of the file similarity metric and in some cases there appear to have been bugs in the core rename detection code where only by the coincidence of the file similarity scoring were the expected results being generated. This renames all the variables in the core rename detection code to be more consistent and hopefully easier to follow which made it a bit easier to reason about the behavior of that code and fix the problems that I was seeing. I think it's in better shape now. There are a couple of tests now that attempt to stress test the rename detection code and they are quite slow. Most of the time is spent setting up the test data on disk and in the index. When we roll out performance improvements for index insertion, it should also speed up these tests I hope.
6fc5a581	2013-07-08T22:42:02	Basic bit vector This is a simple bit vector object that is not resizable after the initial allocation but can be of arbitrary size. It will keep the bti vector entirely on the stack for vectors 64 bits or less, and will allocate the vector on the heap for larger sizes. The API is uniform regardless of storage location. This is very basic right now and all the APIs are inline functions, but it is useful for storing an array of boolean values.
290e1479	2013-07-09T16:17:41	Add GIT_CAP_SSH if library was built with SSH This also adds a test that actually calls git_libgit2_capabilities and git_libgit2_version.

2d160ef7	2013-05-29T16:03:30	allow (ignore) bare slash in gitignore
aa8f0101	2013-04-29T08:59:46	Add git_oid_strcmp and use it for git_oid_streq Add a new git_oid_strcmp that compares a string OID with a hex oid for sort order, and then reimplement git_oid_streq using it. This actually should speed up git_oid_streq because it only reads as far into the string as it needs to, whereas previously it would convert the whole string into an OID and then use git_oid_cmp.
8564a022	2013-04-29T08:51:24	Fix fragile git_oid_ncmp git_oid_ncmp was making some assumptions about the length of the data - this shifts the check to the top of the loop so it will work more robustly, limits the max, and adds some tests to verify the functionality.
917f60c5	2013-04-12T13:04:08	Add tests for oidmap and new cache with threading This adds some basic tests for the oidmap just to make sure that collisions, etc. are dealt with correctly. This also adds some tests for the new caching that check if items are inserted (or not inserted) properly into the cache, and that the cache can hold up in a multithreaded environment without error.

0b061b5b	2013-03-26T11:05:57	Merge pull request #1436 from schu/opts-cache-size opts: allow configuration of odb cache size
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.

32460251	2013-03-18T15:54:35	Fixes and cleanups Get rid of some dead code, tighten things up a bit, and fix a bug with core::env test.
41954a49	2013-03-18T14:19:35	Switch search paths to classic delimited strings This switches the APIs for setting and getting the global/system search paths from using git_strarray to using a simple string with GIT_PATH_LIST_SEPARATOR delimited paths, just as the environment PATH variable would contain. This makes it simpler to get and set the value. I also added code to expand "$PATH" when setting a new value to embed the old value of the path. This means that I no longer require separate actions to PREPEND to the value.
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.
0c468633	2013-03-14T13:40:15	Improved tree iterator internals This updates the tree iterator internals to be more efficient. The tree_iterator_entry objects are now kept as pointers that are allocated from a git_pool, so that we may use git__tsort_r for sorting (which is better than qsort, given that the tree is likely mostly ordered already). Those tree_iterator_entry objects now keep direct pointers to the data they refer to instead of keeping indirect index values. This simplifies a lot of the data structure traversal code. This also adds bsearch to find the start item position for range- limited tree iterators, and is more explicit about using git_path_cmp instead of reimplementing it. The git_path_cmp changed a bit to make it easier for tree_iterators to use it (but it was barely being used previously, so not a big deal). This adds a git_pool_free_array function that efficiently frees a list of pool allocated pointers (which the tree_iterator keeps). Also, added new tests for the git_pool free list functionality that was not previously being tested (or used).
9bc8be3d	2013-02-19T10:25:41	Refine pluggable similarity API This plugs in the three basic similarity strategies for handling whitespace via internal use of the pluggable API. In so doing, I realized that the use of git_buf in the hashsig API was not needed and actually just made it harder to use, so I tweaked that API as well. Note that the similarity metric is still not hooked up in the find_similarity code - this is just setting out the function that will be used.
aa643260	2013-02-15T11:08:02	More tests of file signatures with whitespace opts Seems to be working pretty well...
5e5848eb	2013-02-14T17:25:10	Change similarity metric to sampled hashes This moves the similarity metric code out of buf_text and into a new file. Also, this implements a different approach to similarity measurement based on a Rabin-Karp rolling hash where we only keep the top 100 and bottom 100 hashes. In theory, that should be sufficient samples to given a fairly accurate measurement while limiting the amount of data we keep for file signatures no matter how large the file is.
9c454b00	2013-01-11T22:13:02	Initial implementation of similarity scoring algo This adds a new `git_buf_text_hashsig` type and functions to generate these hash signatures and compare them to give a similarity score. This can be plugged into diff similarity scoring.
56543a60	2013-02-15T16:02:45	Clear up warnings from cppcheck The cppcheck static analyzer generates warnings for a bunch of places in the libgit2 code base. All the ones fixed in this commit are actually false positives, but I've reorganized the code to hopefully make it easier for static analysis tools to correctly understand the structure. I wouldn't do this if I felt like it was making the code harder to read or worse for humans, but in this case, these fixes don't seem too bad and will hopefully make it easier for better analysis tools to get at any real issues.

f63d0ee9	2013-01-17T15:47:10	Move all non-ascii test data to raw hex This takes all of the characters in core::env and makes them use hex sequences instead of keeping tricky character data inline in the test.
0d65acad	2013-01-11T11:24:26	Match binary file check of core git in diff Core git just looks for NUL bytes in files when deciding about is-binary inside diff (although it uses a better algorithm in checkout, when deciding if CRLF conversion should be done). Libgit2 was using the better algorithm in both places, but that is causing some confusion. For now, this makes diff just look for NUL bytes to decide if a file is binary by content in diff.
b8a1ea7c	2013-01-03T11:04:03	Fix core::env cleanup code Mark fake home directories that failed to be created, so we won't try to remove them and have cleanup just use p_rmdir.

34b6f05f	2012-12-26T11:59:07	path: enhance git_path_dirname_r() test coverage
7bf87ab6	2012-11-28T09:58:48	Consolidate text buffer functions There are many scattered functions that look into the contents of buffers to do various text manipulations (such as escaping or unescaping data, calculating text stats, guessing if content is binary, etc). This groups all those functions together into a new file and converts the code to use that. This has two enhancements to existing functionality. The old text stats function is significantly rewritten and the BOM detection code was extended (although largely we can't deal with anything other than a UTF8 BOM).
16248ee2	2012-11-21T11:03:07	Fix up some missing consts in tree & index This fixes some missed places where we can apply const-ness to various public APIs. There are still some index and tree APIs that cannot take const pointers because we sort our `git_vectors` lazily and so we can't reliably bsearch the index and tree content without applying a `git_vector_sort()` first. This also fixes some missed places where size_t can be used and where const can be applied to a couple internal functions.
9094d30b	2012-11-23T11:41:56	Reset all static variables to NULL in clar's __cleanup Without this change, any failed assertion in the second (or a later) test inside a test suite has a chance of double deleting memory, resulting in a heap corruption. See #1096 for details. This leaves alone the test cases where we "just" use cl_git_sandbox_init() and cl_git_sandbox_cleanup(). These methods already take good care to not double delete a repository. Fixes #1096

cccacac5	2012-11-14T22:41:51	Add POSIX compat lstat() variant for win32 The existing p_lstat implementation on win32 is not quite POSIX compliant when setting errno to ENOTDIR. This adds an option to make is be compliant so that code (such as checkout) that cares to have separate behavior for ENOTDIR can use it portably. This also contains a couple of other minor cleanups in the posix_w32.c implementations to avoid unnecessary work.
331e7de9	2012-10-24T17:32:50	Extensions to rmdir and mkdir utilities * Rework GIT_DIRREMOVAL values to GIT_RMDIR flags, allowing combinations of flags * Add GIT_RMDIR_EMPTY_PARENTS flag to remove parent dirs that are left empty after removal * Add GIT_MKDIR_VERIFY_DIR to give an error if item is a file, not a dir (previously an EEXISTS error was ignored, even for files) and enable this flag for git_futils_mkpath2file call * Improve accuracy of error messages from git_futils_mkdir

0d422ec9	2012-10-19T15:40:43	Fix env variable tests with new Win32 path rules The new Win32 global path search was not working with the environment variable tests. But when I fixed the test, the new codes use of getenv() was causing more failures (presumably because of caching on Windows ???). This fixes the global file lookup to always go directly to the Win32 API in a predictable way.

0d64bef9	2012-10-05T15:56:57	Add complex checkout test and then fix checkout This started as a complex new test for checkout going through the "typechanges" test repository, but that revealed numerous issues with checkout, including: * complete failure with submodules * failure to create blobs with exec bits * problems when replacing a tree with a blob because the tree "example/" sorts after the blob "example" so the delete was being processed after the single file blob was created This fixes most of those problems and includes a number of other minor changes that made it easier to do that, including improving the TYPECHANGE support in diff/status, etc.
1a628100	2012-09-21T15:04:39	Make giterr_set_str public There has been discussion for a while about making some set of the `giterr_set` type functions part of the public API for code that is implementing new backends to libgit2. This makes the `giterr_set_str()` and `giterr_set_oom()` functions public.

85bd1746	2012-08-22T16:03:35	Some cleanup suggested during review This cleans up a number of items suggested during code review with @vmg, including: * renaming "outside repo" config API to `git_config_open_default` * killing the `git_config_open_global` API * removing the `git_` prefix from the static functions in fileops * removing some unnecessary functionality from the "cp" command
b769e936	2012-08-01T14:49:47	Don't reference stack vars in cleanup callback If you use the clar cleanup callback function, you can't pass a reference pointer to a stack allocated variable because when the cleanup function runs, the stack won't exist anymore.
ca1b6e54	2012-07-31T17:02:54	Add template dir and set gid to repo init This extends git_repository_init_ext further with support for initializing the repository from an external template directory and with support for the "create shared" type flags that make a set GID repository directory. This also adds tests for much of the new functionality to the existing `repo/init.c` test suite. Also, this adds a bunch of new utility functions including a very general purpose `git_futils_mkdir` (with the ability to make paths and to chmod the paths post-creation) and a file tree copying function `git_futils_cp_r`. Also, this includes some new path functions that were useful to keep the code simple.

b0fe1129	2012-07-10T15:13:30	Add path utilities to resolve relative paths This makes it easy to take a buffer containing a path with relative references (i.e. .. or . path segments) and resolve all of those into a clean path. This can be applied to URLs as well as file paths which can be useful. As part of this, I made the drive-letter detection apply on all platforms, not just windows. If you give a path that looks like "c:/..." on any platform, it seems like we might as well detect that as a rooted path. I suppose if you create a directory named "x:" on another platform and want to use that as the beginning of a relative path under the root directory of your repo, this could cause a problem, but then it seems like you're asking for trouble.
039fc406	2012-07-10T15:10:14	Add a couple of useful git_buf utilities * `git_buf_rfind` (with tests and tests for `git_buf_rfind_next`) * `git_buf_puts_escaped` and `git_buf_puts_escaped_regex` (with tests) to copy strings into a buffer while injecting an escape sequence (e.g. '\') in front of particular characters.

29ef309e	2012-05-25T09:44:56	Make errors for system and global files consistent The error codes from failed lookups of system and global files on Windows were not consistent with the codes returned on other platforms. This makes the error detection patterns match and adds a unit test for the various errors.
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.

9e35d7fd	2012-05-24T13:44:24	Fix bugs in UTF-8 <-> UTF-16 conversion The function to convert UTF-16 to UTF-8 was only allocating a buffer of wcslen(utf16str) bytes for the UTF-8 string, but that is not sufficient if you have multibyte characters, and so when those occured, the conversion was failing. This updates the conversion functions to use the Win APIs to calculate the correct buffer lengths. Also fixes a comparison in the unit tests that would fail if you did not have a particular environment variable set.

41a82592	2012-05-15T14:17:39	Ranged iterators and rewritten git_status_file The goal of this work is to rewrite git_status_file to use the same underlying code as git_status_foreach. This is done in 3 phases: 1. Extend iterators to allow ranged iteration with start and end prefixes for the range of file names to be covered. 2. Improve diff so that when there is a pathspec and there is a common non-wildcard prefix of the pathspec, it will use ranged iterators to minimize excess iteration. 3. Rewrite git_status_file to call git_status_foreach_ext with a pathspec that covers just the one file being checked. Since ranged iterators underlie the status & diff implementation, this is actually fairly efficient. The workdir iterator does end up loading the contents of all the directories down to the single file, which should ideally be avoided, but it is pretty good.
212eb09d	2012-05-13T23:12:51	Add a test to verify FILENAME_MAX Since we now rely on it (at least under Solaris), I figured we probably want to make sure it's accurate. The new test makes sure that creating a file with a name of length FILENAME_MAX+1 fails.

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`.
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.
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.

This commit introduces a could new git error classes, including the catchall class: GITERR_INVALID which I'm using as the class for invalid and out of range values which are detected at too low a level of library to use a higher level classification. For example, an overflow error in parsing an integer or a bad letter in parsing an OID string would generate an error in this class.

Skip UTF-8 BOM in binary detection When a git_buf contains a UTF-8 BOM, the three bytes comprising that BOM are treated as unprintable characters. For a small git_buf, the three BOM characters overwhelm the printable characters. This is problematic when trying to check out a small file as the CR/LF filtering will not apply.

Major rename detection changes After doing further profiling, I found that a lot of time was being spent attempting to insert hashes into the file hash signature when using the rolling hash because the rolling hash approach generates a hash per byte of the file instead of one per run/line of data. To optimize this, I decided to convert back to a run-based file signature algorithm which would be more like core Git. After changing this, a number of the existing tests started to fail. In some cases, this appears to have been because the test was coded to be too specific to the particular results of the file similarity metric and in some cases there appear to have been bugs in the core rename detection code where only by the coincidence of the file similarity scoring were the expected results being generated. This renames all the variables in the core rename detection code to be more consistent and hopefully easier to follow which made it a bit easier to reason about the behavior of that code and fix the problems that I was seeing. I think it's in better shape now. There are a couple of tests now that attempt to stress test the rename detection code and they are quite slow. Most of the time is spent setting up the test data on disk and in the index. When we roll out performance improvements for index insertion, it should also speed up these tests I hope.

Basic bit vector This is a simple bit vector object that is not resizable after the initial allocation but can be of arbitrary size. It will keep the bti vector entirely on the stack for vectors 64 bits or less, and will allocate the vector on the heap for larger sizes. The API is uniform regardless of storage location. This is very basic right now and all the APIs are inline functions, but it is useful for storing an array of boolean values.

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.

Switch search paths to classic delimited strings This switches the APIs for setting and getting the global/system search paths from using git_strarray to using a simple string with GIT_PATH_LIST_SEPARATOR delimited paths, just as the environment PATH variable would contain. This makes it simpler to get and set the value. I also added code to expand "$PATH" when setting a new value to embed the old value of the path. This means that I no longer require separate actions to PREPEND to the value.

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.

Improved tree iterator internals This updates the tree iterator internals to be more efficient. The tree_iterator_entry objects are now kept as pointers that are allocated from a git_pool, so that we may use git__tsort_r for sorting (which is better than qsort, given that the tree is likely mostly ordered already). Those tree_iterator_entry objects now keep direct pointers to the data they refer to instead of keeping indirect index values. This simplifies a lot of the data structure traversal code. This also adds bsearch to find the start item position for range- limited tree iterators, and is more explicit about using git_path_cmp instead of reimplementing it. The git_path_cmp changed a bit to make it easier for tree_iterators to use it (but it was barely being used previously, so not a big deal). This adds a git_pool_free_array function that efficiently frees a list of pool allocated pointers (which the tree_iterator keeps). Also, added new tests for the git_pool free list functionality that was not previously being tested (or used).

Refine pluggable similarity API This plugs in the three basic similarity strategies for handling whitespace via internal use of the pluggable API. In so doing, I realized that the use of git_buf in the hashsig API was not needed and actually just made it harder to use, so I tweaked that API as well. Note that the similarity metric is still not hooked up in the find_similarity code - this is just setting out the function that will be used.

Change similarity metric to sampled hashes This moves the similarity metric code out of buf_text and into a new file. Also, this implements a different approach to similarity measurement based on a Rabin-Karp rolling hash where we only keep the top 100 and bottom 100 hashes. In theory, that should be sufficient samples to given a fairly accurate measurement while limiting the amount of data we keep for file signatures no matter how large the file is.

Clear up warnings from cppcheck The cppcheck static analyzer generates warnings for a bunch of places in the libgit2 code base. All the ones fixed in this commit are actually false positives, but I've reorganized the code to hopefully make it easier for static analysis tools to correctly understand the structure. I wouldn't do this if I felt like it was making the code harder to read or worse for humans, but in this case, these fixes don't seem too bad and will hopefully make it easier for better analysis tools to get at any real issues.

Match binary file check of core git in diff Core git just looks for NUL bytes in files when deciding about is-binary inside diff (although it uses a better algorithm in checkout, when deciding if CRLF conversion should be done). Libgit2 was using the better algorithm in both places, but that is causing some confusion. For now, this makes diff just look for NUL bytes to decide if a file is binary by content in diff.

Consolidate text buffer functions There are many scattered functions that look into the contents of buffers to do various text manipulations (such as escaping or unescaping data, calculating text stats, guessing if content is binary, etc). This groups all those functions together into a new file and converts the code to use that. This has two enhancements to existing functionality. The old text stats function is significantly rewritten and the BOM detection code was extended (although largely we can't deal with anything other than a UTF8 BOM).

There are still some index and tree APIs that cannot take const pointers because we sort our `git_vectors` lazily and so we can't reliably bsearch the index and tree content without applying a `git_vector_sort()` first. This also fixes some missed places where size_t can be used and where const can be applied to a couple internal functions.

Add path utilities to resolve relative paths This makes it easy to take a buffer containing a path with relative references (i.e. .. or . path segments) and resolve all of those into a clean path. This can be applied to URLs as well as file paths which can be useful. As part of this, I made the drive-letter detection apply on all platforms, not just windows. If you give a path that looks like "c:/..." on any platform, it seems like we might as well detect that as a rooted path. I suppose if you create a directory named "x:" on another platform and want to use that as the beginning of a relative path under the root directory of your repo, this could cause a problem, but then it seems like you're asking for trouble.

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.

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

Add a test to verify FILENAME_MAX Since we now rely on it (at least under Solaris), I figured we probably want to make sure it's accurate. The new test makes sure that creating a file with a name of length FILENAME_MAX+1 fails.

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`.

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.

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.

Update clar and remove old helpers This updates to the latest clar which includes the helpers `cl_assert_equal_s` and `cl_assert_equal_i`. Convert the code over to use those and remove the old libgit2-only helpers.

Migrate index, oid, and utils to new errors This includes a few cleanups that came up while converting these files. This commit introduces a could new git error classes, including the catchall class: GITERR_INVALID which I'm using as the class for invalid and out of range values which are detected at too low a level of library to use a higher level classification. For example, an overflow error in parsing an integer or a bad letter in parsing an OID string would generate an error in this class.
