2014-12-29is_hfs_dotgit: loosen over-eager match of \u{..47}Libravatar Jeff King2-12/+35
Our is_hfs_dotgit function relies on the hackily-implemented next_hfs_char to give us the next character that an HFS+ filename comparison would look at. It's hacky because it doesn't implement the full case-folding table of HFS+; it gives us just enough to see if the path matches ".git". At the end of next_hfs_char, we use tolower() to convert our 32-bit code point to lowercase. Our tolower() implementation only takes an 8-bit char, though; it throws away the upper 24 bits. This means we can't have any false negatives for is_hfs_dotgit. We only care about matching 7-bit ASCII characters in ".git", and we will correctly process 'G' or 'g'. However, we _can_ have false positives. Because we throw away the upper bits, code point \u{0147} (for example) will look like 'G' and get downcased to 'g'. It's not known whether a sequence of code points whose truncation ends up as ".git" is meaningful in any language, but it does not hurt to be more accurate here. We can just pass out the full 32-bit code point, and compare it manually to the upper and lowercase characters we care about.

2014-12-17fsck: complain about NTFS ".git" aliases in treesLibravatar Johannes Schindelin2-3/+9
Now that the index can block pathnames that can be mistaken to mean ".git" on NTFS and FAT32, it would be helpful for fsck to notice such problematic paths. This lets servers which use receive.fsckObjects block them before the damage spreads. Note that the fsck check is always on, even for systems without core.protectNTFS set. This is technically more restrictive than we need to be, as a set of users on ext4 could happily use these odd filenames without caring about NTFS. However, on balance, it's helpful for all servers to block these (because the paths can be used for mischief, and servers which bother to fsck would want to stop the spread whether they are on NTFS themselves or not), and hardly anybody will be affected (because the blocked names are variants of .git or git~1, meaning mischief is almost certainly what the tree author had in mind). Ideally these would be controlled by a separate "fsck.protectNTFS" flag. However, it would be much nicer to be able to enable/disable _any_ fsck flag individually, and any scheme we choose should match such a system. Given the likelihood of anybody using such a path in practice, it is not unreasonable to wait until such a system materializes.

2014-12-17read-cache: optionally disallow NTFS .git variantsLibravatar Johannes Schindelin7-0/+34
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.

2014-12-17path: add is_ntfs_dotgit() helperLibravatar Johannes Schindelin2-0/+34
We do not allow paths with a ".git" component to be added to the index, as that would mean repository contents could overwrite our repository files. However, asking "is this path the same as .git" is not as simple as strcmp() on some filesystems. On NTFS (and FAT32), there exist so-called "short names" for backwards-compatibility: 8.3 compliant names that refer to the same files as their long names. As ".git" is not an 8.3 compliant name, a short name is generated automatically, typically "git~1". Depending on the Windows version, any combination of trailing spaces and periods are ignored, too, so that both "git~1." and ".git." still refer to the Git directory. The reason is that 8.3 stores file names shorter than 8 characters with trailing spaces. So literally, it does not matter for the short name whether it is padded with spaces or whether it is shorter than 8 characters, it is considered to be the exact same. The period is the separator between file name and file extension, and again, an empty extension consists just of spaces in 8.3 format. So technically, we would need only take care of the equivalent of this regex: (\.git {0,4}|git~1 {0,3})\. {0,3} However, there are indications that at least some Windows versions might be more lenient and accept arbitrary combinations of trailing spaces and periods and strip them out. So we're playing it real safe here. Besides, there can be little doubt about the intention behind using file names matching even the more lenient pattern specified above, therefore we should be fine with disallowing such patterns. Extra care is taken to catch names such as '.\\.git\\booh' because the backslash is marked as a directory separator only on Windows, and we want to use this new helper function also in fsck on other platforms. A big thank you goes to Ed Thomson and an unnamed Microsoft engineer for the detailed analysis performed to come up with the corresponding fixes for libgit2. This commit adds a function to detect whether a given file name can refer to the Git directory by mistake.

Now that the index can block pathnames that case-fold to ".git" on HFS+, it would be helpful for fsck to notice such problematic paths.

This is technically more restrictive than we need to be, as a set of users on ext4 could happily use these odd filenames without caring about HFS+.

Ideally these would be controlled by a separate "fsck.protectHFS" flag. However, it would be much nicer to be able to enable/disable _any_ fsck flag individually, and any scheme we choose should match such a system.

We do not allow paths with a ".git" component to be added to the index, as that would mean repository contents could overwrite our repository files. However, asking "is this path the same as .git" is not as simple as strcmp() on some filesystems. HFS+'s case-folding does more than just fold uppercase into lowercase (which we already handle with strcasecmp). It may also skip past certain "ignored" Unicode code points, so that (for example) ".gi\u200ct" is mapped ot ".git". The full list of folds can be found in the tables at: https://www.opensource.apple.com/source/xnu/xnu-1504.15.3/bsd/hfs/hfscommon/Unicode/UCStringCompareData.h Implementing a full "is this path the same as that path" comparison would require us importing the whole set of tables. However, what we want to do is much simpler: we only care about checking ".git". We know that 'G' is the only thing that folds to 'g', and so on, so we really only need to deal with the set of ignored code points, which is much smaller.

We check that fsck notices and complains about confusing paths in trees. However, there are a few shortcomings: 1. We check only for these paths as file entries, not as intermediate paths (so ".git" and not ".git/foo"). 2. We check "." and ".." together, so it is possible that we notice only one and not the other. 3. We repeat a lot of boilerplate.

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. But there's not much point. It's unlikely that anybody cares, and it creates a repository that is unexpectedly non-portable to other systems.

2014-12-10read_packed_refs: use a strbuf for reading linesLibravatar Jeff King1-9/+11
Current code uses a fixed PATH_MAX-sized buffer for reading packed-refs lines. This is a reasonable guess, in the sense that git generally cannot work with refs larger than PATH_MAX. However, there are a few cases where it is not great: 1. Some systems may have a low value of PATH_MAX, but can actually handle larger paths in practice. Fixing this code path probably isn't enough to make them work completely with long refs, but it is a step in the right direction. 2. We use fgets, which will happily give us half a line on the first read, and then the rest of the line on the second. This is probably OK in practice, because our refline parser is careful enough to look for the trailing newline on the first line. The second line may look like a peeled line to us, but since "^" is illegal in refnames, it is not likely to come up. Still, it does not hurt to be more careful.
