2015-09-09am --skip/--abort: merge HEAD/ORIG_HEAD tree into indexLibravatar Johannes Schindelin1-1/+1
f8da6801 (am --skip: support skipping while on unborn branch, 2015-06-06) introduced a performance regression to "git am --skip", where it used "read-tree" to reconstruct the index from scratch without reusing the cached stat information. This is a backport of the corresponding patch to the builtin am in 2.6: 3ecc704 (am --skip/--abort: merge HEAD/ORIG_HEAD tree into index, 2015-08-19). Reportedly, it can make a huge difference on Windows, in one case a `git rebase --skip` took 1m40s without, and 5s with, this patch. cf. https://github.com/git-for-windows/git/issues/365 Reported-and-suggested-by: Kim Gybels <kgybels@infogroep.be> Acked-by: Paul Tan <pyokagan@gmail.com> Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2015-09-04show-branch: use a strbuf for reflog descriptionsLibravatar Jeff King1-2/+4
When we show "branch@{0}", we format into a fixed-size buffer using sprintf. This can overflow if you have long branch names. We can fix it by using a temporary strbuf. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2015-09-04read_info_alternates: handle paths larger than PATH_MAXLibravatar Jeff King1-6/+3
This function assumes that the relative_base path passed into it is no larger than PATH_MAX, and writes into a fixed-size buffer. However, this path may not have actually come from the filesystem; for example, add_submodule_odb generates a path using a strbuf and passes it in. This is hard to trigger in practice, though, because the long submodule directory would have to exist on disk before we would try to open its info/alternates file. We can easily avoid the bug, though, by simply creating the filename on the heap. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2015-09-04notes: use a strbuf in add_non_noteLibravatar Jeff King1-9/+10
When we are loading a notes tree into our internal hash table, we also collect any files that are clearly non-notes. We format the name of the file into a PATH_MAX buffer, but unlike true notes (which cannot be larger than a fanned-out sha1 hash), these tree entries can be arbitrarily long, overflowing our buffer. We can fix this by switching to a strbuf. It doesn't even cost us an extra allocation, as we can simply hand ownership of the buffer over to the non-note struct. This is of moderate security interest, as you might fetch notes trees from an untrusted remote. However, we do not do so by default, so you would have to manually fetch into the notes namespace.

2015-09-04verify_absent: allow filenames longer than PATH_MAXLibravatar Jeff King1-7/+10
When unpack-trees wants to know whether a path will overwrite anything in the working tree, we use lstat() to see if there is anything there. But if we are going to write "foo/bar", we can't just lstat("foo/bar"); we need to look for leading prefixes (e.g., "foo"). So we use the lstat cache to find the length of the leading prefix, and copy the filename up to that length into a temporary buffer (since the original name is const, we cannot just stick a NUL in it). The copy we make goes into a PATH_MAX-sized buffer, which will overflow if the prefix is longer than PATH_MAX. How this happens is a little tricky, since in theory PATH_MAX is the biggest path we will have read from the filesystem. But this can happen if: - the compiled-in PATH_MAX does not accurately reflect what the filesystem is capable of - the leading prefix is not _quite_ what is on disk; it contains the next element from the name we are checking. So if we want to write "aaa/bbb/ccc/ddd" and "aaa/bbb" exists, the prefix of interest is "aaa/bbb/ccc". If "aaa/bbb" approaches PATH_MAX, then "ccc" can overflow it. So this can be triggered, but it's hard to do. In particular, you cannot just "git clone" a bogus repo. The verify_absent checks happen before unpack-trees writes anything to the filesystem, so there are never any leading prefixes during the initial checkout, and the bug doesn't trigger. And by definition, these files are larger than PATH_MAX, so writing them will fail, and clone will complain (though it may write a partial path, which will cause a subsequent "git checkout" to hit the bug). We can fix it by creating the temporary path on the heap. The extra malloc overhead is not important, as we are already making at least one stat() call (and probably more for the prefix discovery).

2015-08-31trailer: support multiline titleLibravatar Christian Couder2-4/+25
We currently ignore the first line passed to `git interpret-trailers`, when looking for the beginning of the trailers. Unfortunately this does not work well when a commit is created with a line break in the title, using for example the following command: git commit -m 'place of code: change we made' That's why instead of ignoring only the first line, it is better to ignore the first paragraph.

2015-08-31log: diagnose empty HEAD more clearlyLibravatar Jeff King2-1/+30
If you init or clone an empty repository, the initial message from running "git log" is not very friendly: $ git init Initialized empty Git repository in /home/peff/foo/.git/ $ git log fatal: bad default revision 'HEAD' Let's detect this situation and write a more friendly message: $ git log fatal: your current branch 'master' does not have any commits yet We also detect the case that 'HEAD' points to a broken ref; this should be even less common, but is easy to see. Note that we do not diagnose all possible cases. We rely on resolve_ref, which means we do not get information about complex cases. E.g., "--default master" would use dwim_ref to find "refs/heads/master", but we notice only that "master" does not exist. Similarly, a complex sha1 expression like "--default HEAD^2" will not resolve as a ref. But that's OK. We fall back to a generic error message in those cases, and they are unlikely to be used anyway. Catching an empty or broken "HEAD" improves the common case, and the other cases are not regressed. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2015-08-31commit: don't rewrite shared index unnecessarilyLibravatar David Turner3-5/+15
Remove a cache invalidation which would cause the shared index to be rewritten on as-is commits. When the cache-tree has changed, we need to update it. But we don't necessarily need to update the shared index. So setting active_cache_changed to SOMETHING_CHANGED is unnecessary. Instead, we let update_main_cache_tree just update the CACHE_TREE_CHANGED bit. In order to test this, make test-dump-split-index not segfault on missing replace_bitmap/delete_bitmap. This new codepath is not called now that the test passes, but is necessary to avoid a segfault when the new test is run with the old builtin/commit.c code.

2015-08-28archive-zip: support more than 65535 entriesLibravatar René Scharfe2-4/+91
Support more than 65535 entries cleanly by writing a "zip64 end of central directory record" (with a 64-bit field for the number of entries) before the usual "end of central directory record" (which contains only a 16-bit field). InfoZIP's zip does the same. Archives with 65535 or less entries are not affected. Programs that extract all files like InfoZIP's zip and 7-Zip ignored the field and could extract all files already. Software that relies on the ZIP file directory to show a list of contained files quickly to simulate to normal directory like Windows' built-in ZIP functionality only saw a subset of the included files. Windows supports ZIP64 since Vista according to https://en.wikipedia.org/wiki/Zip_%28file_format%29#ZIP64.

2015-08-28t5004: test ZIP archives with many entriesLibravatar René Scharfe1-0/+40
A ZIP file directory has a 16-bit field for the number of entries it contains. There are 64-bit extensions to deal with that. Demonstrate that git archive --format=zip currently doesn't use them and instead overflows the field. InfoZIP's unzip doesn't care about this field and extracts all files anyway. Software that uses the directory for presenting a filesystem like view quickly -- notably Windows -- depends on it, but doesn't lend itself to an automatic test case easily. Use InfoZIP's zipinfo, which probably isn't available everywhere but at least can provides *some* way to check this field. To speed things up a bit create and commit only a subset of the files and build a fake tree out of duplicates and pass that to git archive.
