Carlos Martín Nieto 8a4d77f9 2015-05-15T12:15:45 path: don't let direach overwrite the callback's error message This function deals with functions doing IO which means the amount of errors that can happen is quit large. It does not help if it always ovewrites the underlying error message with a less understandable version of "something went wrong". Instead, only use this generic message if there was no error set by the callback.
Edward Thomson be3f1049 2015-05-01T11:27:44 diriter: actually use iconv on mac
Edward Thomson cd39e4e2 2015-04-29T18:12:51 git_buf_put_w: introduce utf16->utf8 conversion
Edward Thomson f63a1b72 2015-04-29T17:23:02 git_path_diriter: use FindFirstFile in win32 Using FindFirstFile and FindNextFile in win32 allows us to use the directory information that is returned, instead of us having to get the file attributes all over again, which is a distinct cost savings on win32.
Edward Thomson 5c387b6c 2015-04-29T14:31:59 git_path_diriter: next shouldn't take path ptr The _next method shouldn't take a path pointer (and a path_len pointer) as 100% of current users use the full path and ignore the filename. Plus let's add some docs and a unit test.

Edward Thomson 07bbc045 2015-04-29T11:58:10 git_path_dirload: use git_path_diriter
Edward Thomson edbfc52c 2015-04-29T11:05:27 git_path: introduce 'git_path_diriter' Introduce a new `git_path_diriter` that can iterate directories efficiently for each platform.
Jozef Matula 2a069761 2015-04-08T16:30:44 ISO C90 forbids mixed declarations and code GIT_UNUSED() macro generates code therefore it should be used after variable declarations.
Edward Thomson 4196dd8e 2015-02-26T15:33:58 repository: Introduce "reserved names" A repository can have multiple "reserved names" now, not just a single "short name" for the repository folder itself. Refactor to include a git_repository__reserved_names that returns all the reserved names for a repository.
Edward Thomson 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.
Edward Thomson 392702ee 2015-02-09T23:41:13 allocations: test for overflow of requested size Introduce some helper macros to test integer overflow from arithmetic and set error message appropriately.
Edward Thomson 1fbfcdfc 2015-01-12T15:48:53 git_path_join_unrooted: return base len The documentation for `git_path_join_unrooted` states that the base length will be returned, so that consumers like checkout know where to start creating directories instead of always creating directories at the directory root.
Linquize 6fd00266 2014-12-19T23:54:01 COM0 is a valid path, although Windows Explorer does not allow to create this
Edward Thomson ec74b40c 2014-12-16T18:53:55 Introduce core.protectHFS and core.protectNTFS Validate HFS ignored char ".git" paths when `core.protectHFS` is specified. Validate NTFS invalid ".git" paths when `core.protectNTFS` is specified.
Vicent Marti 8e35527d 2014-12-16T13:03:02 path: Use UTF8 iteration for HFS chars
Edward Thomson 11d67b75 2014-12-10T19:12:16 checkout: disallow bad paths on HFS HFS filesystems ignore some characters like U+200C. When these characters are included in a path, they will be ignored for the purposes of comparison with other paths. Thus, if you have a ".git" folder, a folder of ".git<U+200C>" will also match. Protect our ".git" folder by ensuring that ".git<U+200C>" and friends do not match it.
Edward Thomson a64119e3 2014-11-25T18:13:00 checkout: disallow bad paths on win32 Disallow: 1. paths with trailing dot 2. paths with trailing space 3. paths with trailing colon 4. paths that are 8.3 short names of .git folders ("GIT~1") 5. paths that are reserved path names (COM1, LPT1, etc). 6. paths with reserved DOS characters (colons, asterisks, etc) These paths would (without \\?\ syntax) be elided to other paths - for example, ".git." would be written as ".git". As a result, writing these paths literally (using \\?\ syntax) makes them hard to operate with from the shell, Windows Explorer or other tools. Disallow these.
Edward Thomson 5a7cd1bc 2014-10-25T19:53:53 iterator: free paths when skipping them
Edward Thomson 969b6a47 2014-10-11T11:23:34 is_empty_dir (wi32): cope with empty mount points FindFirstFile will fail with INVALID_HANDLE_VALUE if there are no children to the given path, which can happen if the given path is a file (and obviously has no children) or if the given path is an empty mount point. (Most directories have at least directory entries '.' and '..', but ridiculously another volume mounted in another drive letter's path space do not, and thus have nothing to enumerate.) If FindFirstFile fails, check if this is a directory-like thing (a mount point).

Alan Rogers 7d0ab0fa 2014-07-22T15:08:24 Merge remote-tracking branch 'origin/master' into fix-git-status-list-new-unreadable-folder

Russell Belfer 43a04135 2014-05-08T13:52:46 Pass unconverted data when iconv doesn't like it When using Iconv to convert unicode data and iconv doesn't like the source data (because it thinks that it's not actual UTF-8), instead of stopping the operation, just use the unconverted data. This will generally do the right thing on the filesystem, since that is the source of the non-UTF-8 path data anyhow. This adds some tests for creating and looking up branches with messy Unicode names. Also, this takes the helper function that was previously internal to `git_repository_init` and makes it into `git_path_does_fs_decompose_unicode` which is a useful in tests to understand what the expected results should be.

Philip Kelley c2c81615 2014-04-19T18:05:31 Win32: UTF-8 <-> WCHAR conversion overhaul
Russell Belfer 6a0956e5 2014-04-18T10:32:35 Pop ignore only if whole relative path matches When traversing the directory structure, the iterator pushes and pops ignore files using a vector. Some directories don't have ignore files, so it uses a path comparison to decide when it is right to actually pop the last ignore file. This was only comparing directory suffixes, though, so a subdirectory with the same name as a parent could result in the parent's .gitignore being popped off the list ignores too early. This changes the logic to compare the entire relative path of the ignore file.
Russell Belfer 7167fd7e 2014-04-07T11:51:12 vmg is always right
Russell Belfer c813b345 2014-04-07T11:45:32 Fix bug with multiple iconv conversions in one dir The internal buffer in the `git_path_iconv_t` structure was not being reset before the calls to `iconv` were made to convert data, so if there were multiple decomposed Unicode paths in a single directory, paths after the first one were being appended to the first instead of treated as independent data.
Russell Belfer d3bc95fd 2014-03-25T12:37:05 Update behavior for untracked sub-repos When a directory containing a .git directory (or even just a plain gitlink) was found, libgit2 was going out of its way to treat it specially. This seemed like it was necessary because the diff code was not originally emulating Git's behavior for untracked directories correctly (i.e. scanning for ignored vs untracked items inside). Now that libgit2 diff mimics Git's untracked directory behavior, the special handling for contained Git repos is actually incorrect and this commit rips it out.
Carlos Martín Nieto a213a7bf 2014-03-05T20:32:53 refdb: catch a directory disappearing If a directory disappears between the time we look up the entries of its parent and the time when we go to look at it, we should ignore the error and move forward. This fixes #2046.

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 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.
Vicent Marti 0bfa7323 2013-11-01T17:07:44 iconv: Do not fake an API when iconv is not available
Russell Belfer 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.
Russell Belfer 618b7689 2013-10-02T12:06:26 Wrap iconv stuff and write tests This adds a simple wrapper around the iconv APIs and uses it instead of the old code that was inlining the iconv stuff. This makes it possible for me to test the iconv logic in isolation. A "no iconv" version of the API was defined with macros so that I could have fewer ifdefs in the code itself.
Russell Belfer d0849f83 2013-10-02T11:07:18 Simplify git_path_is_empty_dir implementation This simplifies git_path_is_empty_dir on both Windows (getting rid of git_buf allocation inside the function) and other platforms (by just using git_path_direach), and adds tests for the function, and uses the function to simplify some existing tests.
Russell Belfer 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.
Russell Belfer 2fe54afa 2013-09-30T16:58:33 Put hooks in place for precompose in dirload fn This doesn't actual do string precompose but it puts the hooks in place into the iterators and the git_path_dirload function so that the actual precompose work is ready to go.
Edward Thomson 5c3b8ef4 2013-09-24T14:52:58 Ignore files that disappear while iterating On occasion, files can disappear while we're iterating the filesystem, between calls to readdir and stat. Let's pretend those didn't exist in the first place.
Russell Belfer a9f51e43 2013-09-11T22:00:36 Merge git_buf and git_buffer This makes the git_buf struct that was used internally into an externally available structure and eliminates the git_buffer. As part of that, some of the special cases that arose with the externally used git_buffer were blended into the git_buf, such as being careful about git_buf objects that may have a NULL ptr and allowing for bufs with a valid ptr and size but zero asize as a way of referring to externally owned data.

Russell Belfer ee065601 2013-08-13T09:53:56 Minor win32 fixes and improvements This is just a bunch of small fixes that I noticed while looking at the UTF8 and UTF16 path stuff. It fixes a slowdown in looking for an empty directory (not exiting loop asap), makes the dir name in the git__DIR structure be a GIT_FLEX_ARRAY to save an allocation, and fixes some slightly odd assumptions in the cl_getenv helper.

Russell Belfer ba8b8c04 2013-08-07T09:17:20 Improve building ignore file lists The routines to push and pop ignore files while traversing a directory had some issues. In particular, setting up the initial list would sometimes push an ignore file before it ought to be applied if the starting path was a directory containing an ignore file. Also, the pop function was not always matching the right part of the path and would fail to pop ignores from the list in some cases. This adds some tests that exercise a particular problematic case and then fixes the problems that I could find related to this. At some point, I'd like to isolate this ignore rule management code and rewrite it, but that's a larger project and right now, I'll opt to just try to fix the broken behaviors.

Russell Belfer 65025cb8 2013-03-18T17:24:13 Three submodule status bug fixes 1. Fix sort order problem with submodules where "mod" was sorting after "mod-plus" because they were being sorted as "mod/" and "mod-plus/". This involved pushing the "contains a .git entry" test significantly lower in the stack. 2. Reinstate behavior that a directory which contains a .git entry will be treated as a submodule during iteration even if it is not yet added to the .gitmodules. 3. Now that any directory containing .git is reported as submodule, we have to be more careful checking for GIT_EEXISTS when we do a submodule lookup, because that is the error code that is returned by git_submodule_lookup when you try to look up a directory containing .git that has no record in gitmodules or the index.
Russell Belfer 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).

This fixes it and adds tests for it, and also extends it with the ability to update the start/end range strings when an iterator is reset.
Russell Belfer 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).
Russell Belfer 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.

Russell Belfer 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.

Russell Belfer 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.
