2015-10-29Merge branch 'dt/name-hash-dir-entry-fix'Libravatar Junio C Hamano1-15/+1
The name-hash subsystem that is used to cope with case insensitive filesystems keeps track of directories and their on-filesystem cases for all the paths in the index by holding a pointer to a randomly chosen cache entry that is inside the directory (for its ce->ce_name component). This pointer was not updated even when the cache entry was removed from the index, leading to use after free. This was fixed by recording the path for each directory instead of borrowing cache entries and restructuring the API somewhat. * dt/name-hash-dir-entry-fix: name-hash: don't reuse cache_entry in dir_entry

2015-10-21name-hash: don't reuse cache_entry in dir_entryLibravatar David Turner1-15/+1
Stop reusing cache_entry in dir_entry; doing so causes a use-after-free bug. During merges, we free entries that we no longer need in the destination index. But those entries might have also been stored in the dir_entry cache, and when a later call to add_to_index found them, they would be used after being freed. To prevent this, change dir_entry to store a copy of the name instead of a pointer to a cache_entry. This entails some refactoring of code that expects the cache_entry. Keith McGuigan <kmcguigan@twitter.com> diagnosed this bug and wrote the initial patch, but this version does not use any of Keith's code.

2015-06-08read-cache: fix untracked cache invalidation when split-index is usedLibravatar Nguyễn Thái Ngọc Duy1-1/+2
Before this change, t7063.17 fails. The actual action though happens at t7063.16 where the entry "two" is added back to index after being removed in the .13. Here we expect a directory invalidate at .16 and none at .17 where untracked cache is refreshed. But things do not go as expected when GIT_TEST_SPLIT_INDEX is set. The different behavior that happens at .16 when split index is used: the entry "two", when deleted at .13, is simply marked "deleted". When .16 executes, the entry resurfaces from the version in base index. This happens in merge_base_index() where add_index_entry() is called to add "two" back from the base index. This is where the bug comes from. The add_index_entry() is called with ADD_CACHE_KEEP_CACHE_TREE flag because this version of "two" is not new, it does not break either cache-tree or untracked cache. The code should check this flag and not invalidate untracked cache. This causes a second invalidation violates test expectation. The fix is obvious.

2015-05-28read-cache.c: drop PROT_WRITE from mmap of indexLibravatar Jeff King1-1/+1
Once upon a time, git's in-memory representation of a cache entry actually pointed to the mmap'd on-disk data. So in 520fc24 (Allow writing to the private index file mapping., 2005-04-26), we specified PROT_WRITE so that we could tweak the entries while we run (in our own MAP_PRIVATE copy-on-write version, of course). Later, 7a51ed6 (Make on-disk index representation separate from in-core one, 2008-01-14) stopped doing this; we copy the data into our in-core representation, and then drop the mmap immediately. We can therefore drop the PROT_WRITE flag. It's probably not hurting anything as it is, but it's potentially confusing. Note that we could also mark the mapping as "const" to verify that we never write to it. However, we don't typically do that for our other maps, as it then requires casting to munmap() it.

2015-03-23read-cache: fix memleakLibravatar Stefan Beller1-5/+2
`ce` is allocated in make_cache_entry and should be freed if it is not used any more. refresh_cache_entry as a wrapper around refresh_cache_ent will either return - the `ce` given as the parameter, when it was up-to-date; - a new updated cache entry which is allocated to new memory; or - a NULL when refreshing failed. In the latter two cases, the original cache-entry `ce` is not used and needs to be freed. The rule can be expressed as "if the return value from refresh is different from the original ce, ce is no longer used."

2015-03-20read-cache: fix reading of split indexLibravatar Thomas Gummerer1-19/+23
The split index extension uses ewah bitmaps to mark index entries as deleted, instead of removing them from the index directly. This can result in an on-disk index, in which entries of stage #0 and higher stages appear, which are removed later when the index bases are merged. 15999d0 read_index_from(): catch out of order entries when reading an index file introduces a check which checks if the entries are in order after each index entry is read in do_read_index. This check may however fail when a split index is read. Fix this by moving checking the index after we know there is no split index or after the split index bases are successfully merged instead.

2015-03-12untracked cache: invalidate at index addition or removalLibravatar Nguyễn Thái Ngọc Duy1-0/+4
Ideally we should implement untracked_cache_remove_from_index() and untracked_cache_add_to_index() so that they update untracked cache right away instead of invalidating it and wait for read_directory() next time to deal with it. But that may need some more work in unpack-trees.c. So stay simple as the first step. The new call in add_index_entry_with_check() may look strange because new calls usually stay close to cache_tree_invalidate_path(). We do it a bit later than c_t_i_p() in this function because if it's about replacing the entry with the same name, we don't care (but cache-tree does).

2014-12-17read-cache: optionally disallow NTFS .git variantsLibravatar Johannes Schindelin1-0/+2
The point of disallowing ".git" in the index is that we would never want to accidentally overwrite files in the repository directory. But this means we need to respect the filesystem's idea of when two paths are equal. The prior commit added a helper to make such a comparison for NTFS and FAT32; let's use it in verify_path(). We make this check optional for two reasons: 1. It restricts the set of allowable filenames, which is unnecessary for people who are not on NTFS nor FAT32. In practice this probably doesn't matter, though, as the restricted names are rather obscure and almost certainly would never come up in practice. 2. It has a minor performance penalty for every path we insert into the index. This patch ties the check to the core.protectNTFS config option. Though this is expected to be most useful on Windows, we allow it to be set everywhere, as NTFS may be mounted on other platforms. The variable does default to on for Windows, though.

However, on case-insensitive file systems, ".Git" or ".GIT" is the same. We should catch and prevent those, too. Note that technically we could allow this for repos on case-sensitive filesystems.

For now, we still make sure to allocate at least PATH_MAX characters for the strbuf because resolve_symlink() doesn't know how to expand the space for its return value. (That will be fixed in a moment.) Another alternative would be to just use a strbuf as scratch space in lock_file() but then store a pointer to the naked string in struct lock_file. But lock_file objects are often reused. By reusing the same strbuf, we can avoid having to reallocate the string most times when a lock_file object is reused.

2014-10-01lockfile: avoid transitory invalid statesLibravatar Michael Haggerty1-0/+1
Because remove_lock_file() can be called any time by the signal handler, it is important that any lock_file objects that are in the lock_file_list are always in a valid state. And since lock_file objects are often reused (but are never removed from lock_file_list), that means we have to be careful whenever mutating a lock_file object to always keep it in a well-defined state. This was formerly not the case, because part of the state was encoded by setting lk->filename to the empty string vs. a valid filename. It is wrong to assume that this string can be updated atomically; for example, even strcpy(lk->filename, value) is unsafe. But the old code was even more reckless; for example, strcpy(lk->filename, path); if (!(flags & LOCK_NODEREF)) resolve_symlink(lk->filename, max_path_len); strcat(lk->filename, ".lock"); During the call to resolve_symlink(), lk->filename contained the name of the file that was being locked, not the name of the lockfile. If a signal were raised during that interval, then the signal handler would have deleted the valuable file! We could probably continue to use the filename field to encode the state by being careful to write characters 1..N-1 of the filename first, and then overwrite the NUL at filename[0] with the first character of the filename, but that would be awkward and error-prone. So, instead of using the filename field to determine whether the lock_file object is active, add a new field "lock_file::active" for this purpose. Be careful to set this field only when filename really contains the name of a file that should be deleted on cleanup.

2014-08-07read-cache.c: replace `git_config()` with `git_config_get_*()` familyLibravatar Tanay Abhra1-11/+3
Use `git_config_get_*()` family instead of `git_config()` to take advantage of the config-set API which provides a cleaner control flow. Use an intermediate value, as `version` can not be used directly in git_config_get_int() due to incompatible type.

"git status", even though it is a read-only operation, tries to update the index with refreshed lstat(2) info to optimize future accesses to the working tree opportunistically, but this could race with a "read-write" operation that modify the index while it is running. Detect such a race and avoid overwriting the index. * ym/fix-opportunistic-index-update-race: read-cache.c: verify index file before we opportunistically update it wrapper.c: add xpread() similar to xread()
