3547b122	2015-10-30T21:36:51	filebuf: use an internal buffer This reduces the chances of a crash in the thread tests. This shouldn't affect general usage too much, since the main usage of these functions are to read into an empty buffer.
eb597799	2015-10-29T21:12:37	filebuf: use a checksum to detect file changes Instead of relying on the size and timestamp, which can hide changes performed in the same second, hash the file content's when we care about detecting changes.

81aaf370	2015-09-17T11:26:38	mkdir: chmod existing paths with `GIT_MKDIR_CHMOD`
e24c60db	2015-09-17T09:42:05	mkdir: find component paths for mkdir_relative `git_futils_mkdir` does not blindly call `git_futils_mkdir_relative`. `git_futils_mkdir_relative` is used when you have some base directory and want to create some path inside of it, potentially removing blocking symlinks and files in the process. This is not suitable for a general recursive mkdir within the filesystem. Instead, when `mkdir` is being recursive, locate the first existent parent directory and use that as the base for `mkdir_relative`.
ac2fba0e	2015-09-16T15:07:27	git_futils_mkdir_*: make a relative-to-base mkdir Untangle git_futils_mkdir from git_futils_mkdir_ext - the latter assumes that we own everything beneath the base, as if it were being called with a base of the repository or working directory, and is tailored towards checkout and ensuring that there is no bogosity beneath the base that must be cleaned up. This is (at best) slow and (at worst) unsafe in the larger context of a filesystem where we do not own things and cannot do things like unlink symlinks that are in our way.
edef91ee	2015-05-15T12:23:27	fileops: set an error on write error for file copy We set an error if we get an error when reading, but we don't bother setting an error message for write failing. This causes a cryptic error to be shown to the user when the target filesystem is full.
54738368	2015-05-15T12:18:05	fileops: set an error message if we fail to link a file Now that `git_path_direach` lets us specify an error message to report, set an appropriate error message while linking.

f1453c59	2015-02-12T12:19:37	Make our overflow check look more like gcc/clang's Make our overflow checking look more like gcc and clang's, so that we can substitute it out with the compiler instrinsics on platforms that support it. This means dropping the ability to pass `NULL` as an out parameter. As a result, the macros also get updated to reflect this as well.

668ae2dd	2014-08-22T10:05:09	Allow mkdir helper to skip parent errors Our mkdir helper was failing is a parent directory was not accessible even if the child directory could be created. This changes the helper to keep trying child directories even when the parent is unwritable.
94f742ba	2014-05-28T10:18:05	fileops: allow linking files when copying directory structures When passed the LINK_FILES flag, the recursive copy will hardlink files instead of copying them.
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.
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.

9cfce273	2013-12-12T12:11:38	Cleanups, renames, and leak fixes This renames git_vector_free_all to the better git_vector_free_deep and also contains a couple of memory leak fixes based on valgrind checks. The fixes are specifically: failure to free global dir path variables when not compiled with threading on and failure to free filters from the filter registry that had not be initialized fully.
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.
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.

14997dc5	2013-10-08T12:45:43	More filemode cleanups for FAT on MacOS This cleans up some additional issues. The main change is that on a filesystem that doesn't support mode bits, libgit2 will now create new blobs with GIT_FILEMODE_BLOB always instead of being at the mercy to the filesystem driver to report executable or not. This means that if "core.filemode" lies and claims that filemode is not supported, then we will ignore the executable bit from the filesystem. Previously we would have allowed it. This adds an option to the new git_repository_reset_filesystem to recurse through submodules if desired. There may be other types of APIs that would like a "recurse submodules" option, but this one is particularly useful. This also has a number of cleanups, etc., for related things including trying to give better error messages when problems come up from the filesystem. For example, the FAT filesystem driver on MacOS appears to return errno EINVAL if you attempt to write a filename with invalid UTF-8 in it. We try to capture that with a better error message now.
219d3457	2013-10-01T16:12:15	Initial iconv hookup for precomposed unicode This hooks up git_path_direach and git_path_dirload so that they will take a flag indicating if directory entry names should be tested and converted from decomposed unicode to precomposed form. This code will only come into play on the Apple platform and even then, only when certain types of filesystems are used. This involved adding a flag to these functions which involved changing a lot of places in the code. This was an opportunity to do a bit of code cleanup here and there, for example, getting rid of the git_futils_cleanupdir_r function in favor of a simple flag to git_futils_rmdir_r to not remove the top level entry. That ended up adding depth tracking during rmdir_r which led to a safety check for infinite directory recursion. Yay. This hasn't actually been tested on the Mac filesystems where the issue occurs. I still need to get test environment for that.

13f36ffb	2013-09-13T16:30:21	Add clar helpers for testing file equality These are a couple of new clar helpers for testing that a file has expected contents that I extracted from the checkout code. Actually wrote this as part of an abandoned earlier attempt at a new filters API, but it will be useful now for some of the tests I'm going to write.
a3aa5f4d	2013-09-11T12:45:20	Add simple global shutdown hooks Increasingly there are a number of components that want to do some cleanup at global shutdown time (at least if there are not going to be memory leaks). This creates a very simple system of shutdown hooks that will be invoked by git_threads_shutdown. Right now, the maximum number of hooks is hardcoded, but since adding a hook is not a public API, it should be fine and I thought it was better to start off with really simple code.

9ccdb211	2013-08-13T10:55:37	fileops: stat() before open()ing in git_futils_readbuffer_updated() This reverts refactoring done in 13224ea4aad9a1b3c9cc4c992ceaea9af623e047 that introduces a performance regression for NFS when reading files that don't exist. open() forces a cache invalidation on NFS, while stat()ing a file just uses the cache and is very quick. To give a specific example, say you have a repo with a thousand packed refs. Before this change, looking up every single one ould incur a thousand slow open() calls. With this change, it's a thousand fast stat() calls.

32c12ea6	2013-06-24T09:19:24	Work around reparse point stat issues In theory, p_stat should never return an S_ISLNK result, but due to the current implementation on Windows with mount points it is possible that it will. For now, work around that by allowing a link in the path to a directory being created. If it is really a problem, then the issue will be caught on the next iteration of the loop, but typically this will be the right thing to do.

f7e56150	2013-06-05T15:41:42	Make mkdir early exit cases clearer There are two places where git_futils_mkdir should exit early or at least do less. The first is when using GIT_MKDIR_SKIP_LAST and having that flag leave no directory left to create; it was being handled previously, but the behavior was subtle. Now I put in a clear explicit check that exits early in that case. The second is when there is no directory to create, but there is a valid path that should be verified. I shifted the logic a bit so we'll be better about not entering the loop than that happens.
999d4405	2013-06-05T12:02:28	Simplify git_futils_mkdir This routine was (is) pretty complicated, but given the recent changes, it seemed like it could be simplified a bit.

b832ecf7	2013-06-05T09:46:51	Ensure git_futils_mkdir won't mkdir root This makes sure that git_futils_mkdir always skips over the root directory at a minimum, even on platforms where the root is not simply '/'. Also, this removes the GIT_WIN32 ifdef in favor of making EACCES as a potentially recoverable error on all platforms.
daf98cb2	2013-06-04T14:49:39	Allow creation of directories under the volume root in Win32 We ran into an issue where cloning a repository to a folder directly underneath the root of a volume (e.g. 'd:\libgit2') would fail with an access denied error. This was traced down to a call to make a directory that is the root (e.g. 'd:') could return an error indicated access denied instead of an error indicating the path already exists. This change now handles the access denied error on Win32 and checks for the existence of the folder.
4742148d	2013-05-20T13:41:39	Add more diff rename detection tests This adds a bunch more rename detection tests including checks vs the working directory, the new exact match options, some more whitespace variants, etc. This also adds a git_futils_writebuffer helper function and uses it in checkout. This is mainly added because I wanted an easy way to write out a git_buf to disk inside my test code.

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.

The expression is calculated as following: 'A = (B == C)' Unsigned type is never < 0
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.

18f08264	2013-02-27T13:44:15	Make mode handling during init more like git When creating files, instead of actually using GIT_FILEMODE_BLOB and the other various constants that happen to correspond to mode values, apparently I should be just using 0666 and 0777, and relying on the umask to clear bits and make the value sane. This fixes the rules for copying a template directory and fixes the checks to match that new behavior. (Further changes to the checkout logic to follow separately.)
3c42e4ef	2013-02-26T11:43:14	Fix initialization of repo directories When PR #1359 removed the hooks from the test resources/template directory, it made me realize that the tests for git_repository_init_ext using templates must be pretty shabby because we could not have been testing if the hooks were getting created correctly. So, this started with me recreating a couple of hooks, including a sample and symlink, and adding tests that they got created correctly in the various circumstances, including with the SHARED modes, etc. Unfortunately this uncovered some issues with how directories and symlinks were copied and chmod'ed. Also, there was a FIXME in the code related to the chmod behavior as well. Going back over the directory creation logic for setting up a repository, I found it was a little difficult to read and could result in creating and/or chmod'ing directories that the user almost certainly didn't intend. So that let to this work which makes repo initialization much more careful (and hopefully easier to follow). It required a couple of extensions / changes to core fileops utilities, but I also think those are for the better, at least for git_futils_cp_r in terms of being careful about what actions it takes.

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.
ad9a921b	2012-11-08T17:05:07	Rework checkout with new strategy options This is a major reworking of checkout strategy options. The checkout code is now sensitive to the contents of the HEAD tree and the new options allow you to update the working tree so that it will match the index content only when it previously matched the contents of the HEAD. This allows you to, for example, to distinguish between removing files that are in the HEAD but not in the index, vs just removing all untracked files. Because of various corner cases that arise, etc., this required some additional capabilities in rmdir and other utility functions. This includes the beginnings of an implementation of code to read a partial tree into the index based on a pathspec, but that is not enabled because of the possibility of creating conflicting index entries.

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.
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.

mkdir: find component paths for mkdir_relative `git_futils_mkdir` does not blindly call `git_futils_mkdir_relative`. `git_futils_mkdir_relative` is used when you have some base directory and want to create some path inside of it, potentially removing blocking symlinks and files in the process. This is not suitable for a general recursive mkdir within the filesystem. Instead, when `mkdir` is being recursive, locate the first existent parent directory and use that as the base for `mkdir_relative`.

git_futils_mkdir_*: make a relative-to-base mkdir Untangle git_futils_mkdir from git_futils_mkdir_ext - the latter assumes that we own everything beneath the base, as if it were being called with a base of the repository or working directory, and is tailored towards checkout and ensuring that there is no bogosity beneath the base that must be cleaned up. This is (at best) slow and (at worst) unsafe in the larger context of a filesystem where we do not own things and cannot do things like unlink symlinks that are in our way.

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.

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.

More filemode cleanups for FAT on MacOS This cleans up some additional issues. The main change is that on a filesystem that doesn't support mode bits, libgit2 will now create new blobs with GIT_FILEMODE_BLOB always instead of being at the mercy to the filesystem driver to report executable or not. This means that if "core.filemode" lies and claims that filemode is not supported, then we will ignore the executable bit from the filesystem. Previously we would have allowed it. This adds an option to the new git_repository_reset_filesystem to recurse through submodules if desired. There may be other types of APIs that would like a "recurse submodules" option, but this one is particularly useful. This also has a number of cleanups, etc., for related things including trying to give better error messages when problems come up from the filesystem. For example, the FAT filesystem driver on MacOS appears to return errno EINVAL if you attempt to write a filename with invalid UTF-8 in it. We try to capture that with a better error message now.

Initial iconv hookup for precomposed unicode This hooks up git_path_direach and git_path_dirload so that they will take a flag indicating if directory entry names should be tested and converted from decomposed unicode to precomposed form. This code will only come into play on the Apple platform and even then, only when certain types of filesystems are used. This involved adding a flag to these functions which involved changing a lot of places in the code. This was an opportunity to do a bit of code cleanup here and there, for example, getting rid of the git_futils_cleanupdir_r function in favor of a simple flag to git_futils_rmdir_r to not remove the top level entry. That ended up adding depth tracking during rmdir_r which led to a safety check for infinite directory recursion. Yay. This hasn't actually been tested on the Mac filesystems where the issue occurs. I still need to get test environment for that.

This creates a very simple system of shutdown hooks that will be invoked by git_threads_shutdown.

fileops: stat() before open()ing in git_futils_readbuffer_updated() This reverts refactoring done in 13224ea4aad9a1b3c9cc4c992ceaea9af623e047 that introduces a performance regression for NFS when reading files that don't exist. open() forces a cache invalidation on NFS, while stat()ing a file just uses the cache and is very quick. To give a specific example, say you have a repo with a thousand packed refs. Before this change, looking up every single one ould incur a thousand slow open() calls. With this change, it's a thousand fast stat() calls.

Make mkdir early exit cases clearer There are two places where git_futils_mkdir should exit early or at least do less. The first is when using GIT_MKDIR_SKIP_LAST and having that flag leave no directory left to create; it was being handled previously, but the behavior was subtle. Now I put in a clear explicit check that exits early in that case. The second is when there is no directory to create, but there is a valid path that should be verified. I shifted the logic a bit so we'll be better about not entering the loop than that happens.

Allow creation of directories under the volume root in Win32 We ran into an issue where cloning a repository to a folder directly underneath the root of a volume (e.g. 'd:\libgit2') would fail with an access denied error. This was traced down to a call to make a directory that is the root (e.g. 'd:') could return an error indicated access denied instead of an error indicating the path already exists. This change now handles the access denied error on Win32 and checks for the existence of the folder.

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.

This fixes the rules for copying a template directory and fixes the checks to match that new behavior. (Further changes to the checkout logic to follow separately.)

Fix initialization of repo directories When PR #1359 removed the hooks from the test resources/template directory, it made me realize that the tests for git_repository_init_ext using templates must be pretty shabby because we could not have been testing if the hooks were getting created correctly. So, this started with me recreating a couple of hooks, including a sample and symlink, and adding tests that they got created correctly in the various circumstances, including with the SHARED modes, etc. Unfortunately this uncovered some issues with how directories and symlinks were copied and chmod'ed. Also, there was a FIXME in the code related to the chmod behavior as well. Going back over the directory creation logic for setting up a repository, I found it was a little difficult to read and could result in creating and/or chmod'ing directories that the user almost certainly didn't intend. So that let to this work which makes repo initialization much more careful (and hopefully easier to follow). It required a couple of extensions / changes to core fileops utilities, but I also think those are for the better, at least for git_futils_cp_r in terms of being careful about what actions it takes.

More checkout improvements This flips checkout back to be driven off the changes between the baseline and the target trees. This reinstates the complex code for tracking the contents of the working directory, but overall, I think the resulting logic is easier to follow.

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.

Rework checkout with new strategy options This is a major reworking of checkout strategy options. The checkout code is now sensitive to the contents of the HEAD tree and the new options allow you to update the working tree so that it will match the index content only when it previously matched the contents of the HEAD. This allows you to, for example, to distinguish between removing files that are in the HEAD but not in the index, vs just removing all untracked files. Because of various corner cases that arise, etc., this required some additional capabilities in rmdir and other utility functions. This includes the beginnings of an implementation of code to read a partial tree into the index based on a pathspec, but that is not enabled because of the possibility of creating conflicting index entries.

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

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.

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.
