2015-03-20refs.c: drop curate_packed_refsLibravatar Jeff King1-1/+1
When we delete a ref, we have to rewrite the entire packed-refs file. We take this opportunity to "curate" the packed-refs file and drop any entries that are crufty or broken. Dropping broken entries (e.g., with bogus names, or ones that point to missing objects) is actively a bad idea, as it means that we lose any notion that the data was there in the first place. Aside from the general hackiness that we might lose any information about ref "foo" while deleting an unrelated ref "bar", this may seriously hamper any attempts by the user at recovering from the corruption in "foo". They will lose the sha1 and name of "foo"; the exact pointer may still be useful even if they recover missing objects from a different copy of the repository. But worse, once the ref is gone, there is no trace of the corruption. A follow-up "git prune" may delete objects, even though it would otherwise bail when seeing corruption. We could just drop the "broken" bits from curate_packed_refs, and continue to drop the "crufty" bits: refs whose loose counterpart exists in the filesystem. This is not wrong to do, and it does have the advantage that we may write out a slightly smaller packed-refs file. But it has two disadvantages: 1. It is a potential source of races or mistakes with respect to these refs that are otherwise unrelated to the operation. To my knowledge, there aren't any active problems in this area, but it seems like an unnecessary risk. 2. We have to spend time looking up the matching loose refs for every item in the packed-refs file. If you have a large number of packed refs that do not change, that outweighs the benefit from writing out a smaller packed-refs file (it doesn't get smaller, and you do a bunch of directory traversal to find that out).

2015-03-20repack: turn on "ref paranoia" when doing a destructive repackLibravatar Jeff King1-1/+1
If we are repacking with "-ad", we will drop any unreachable objects. Likewise, using "-Ad --unpack-unreachable=<time>" will drop any old, unreachable objects. In these cases, we want to make sure the reachability we compute with "--all" is complete. We can do this by passing GIT_REF_PARANOIA=1 in the environment to pack-objects. Note that "-Ad" is safe already, because it only loosens unreachable objects. It is up to "git prune" to avoid deleting them.

2015-03-20prune: turn on ref_paranoia flagLibravatar Jeff King1-2/+2
Prune should know about broken objects at the tips of refs, so that we can feed them to our traversal rather than ignoring them. It's better for us to abort the operation on the broken object than it is to start deleting objects with an incomplete view of the reachability namespace. Note that for missing objects, aborting is the best we can do. For a badly-named ref, we technically could use its sha1 as a reachability tip. However, the iteration code just feeds us a null sha1, so there would be a reasonable amount of code involved to pass down our wishes. It's not really worth trying to do better, because this is a case that should happen extremely rarely, and the message we provide: fatal: unable to parse object: refs/heads/bogus:name is probably enough to point the user in the right direction.

2015-03-20t5312: test object deletion code paths in a corrupted repositoryLibravatar Jeff King1-0/+114
When we are doing a destructive operation like "git prune", we want to be extra careful that the set of reachable tips we compute is valid. If there is any corruption or oddity, we are better off aborting the operation and letting the user figure things out rather than plowing ahead and possibly deleting some data that cannot be recovered. The tests here include: 1. Pruning objects mentioned only be refs with invalid names. This used to abort prior to d0f810f (refs.c: allow listing and deleting badly named refs, 2014-09-03), but since then we silently ignore the tip. Likewise, we test repacking that can drop objects (either "-ad", which drops anything unreachable, or "-Ad --unpack-unreachable=<time>", which tries to optimize out a loose object write that would be directly pruned). 2. Pruning objects when some refs point to missing objects. We don't know whether any dangling objects would have been reachable from the missing objects. We are better to keep them around, as they are better than nothing for helping the user recover history. 3. Packed refs that point to missing objects can sometimes be dropped. By itself, this is more of an annoyance (you do not have the object anyway; even if you can recover it from elsewhere, all you are losing is a placeholder for your state at the time of corruption). But coupled with (2), if we drop the ref and then go on to prune, we may lose unrecoverable objects. Note that we use test_might_fail for some of the operations. In some cases, it would be appropriate to abort the operation, and in others, it might be acceptable to continue but taking the information into account. The tests don't care either way, and check only for data loss. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2015-03-19filter_ref: make a copy of extra "sought" entriesLibravatar Jeff King1-3/+10
If the server supports allow_tip_sha1_in_want, we add any unmatched raw-sha1 entries in our "sought" list of refs to the list of refs we will ask the other side for. We do so by inserting the original "struct ref" directly into our list, rather than making a copy. This has several problems. The most minor problem is that one cannot ever free the resulting list; it contains structs that are copies of the remote refs (made earlier by fetch_pack) along with sought refs that are referenced elsewhere. But more importantly that we set the ref->next pointer to NULL, chopping off the remainder of any existing list that the ref was a part of. We get the set of "sought" refs in an array rather than a linked list, but that array is often in turn generated from a list. The test modification in t5516 demonstrates this. Rather than fetching just an exact sha1, we fetch that sha1 plus another ref: - we build a linked list of refs to fetch when do_fetch calls get_ref_map; the exact sha1 is first, followed by the named ref ("refs/heads/extra" in this case). - we pass that linked list to transport_fetch_ref, which squashes it into an array of pointers - that array goes to fetch_pack, which calls filter_ref. There we generate the want list from a mix of what the remote side has advertised, and the "sought" entry for the exact sha1. We set the sought entry's "next" pointer to NULL. - after we return from transport_fetch_refs, we then try to update the refs by following the linked list. But our list is now truncated, and we do not update refs/heads/extra at all. We can fix this by making a copy of the ref. There's nothing that fetch_pack does to it that must be reflected in the original "sought" list (and indeed, if that were the case we would have a serious bug, because it is only exact-sha1 entries which are treated this way).

2015-03-12upload-pack: fix transfer.hiderefs over smart-httpLibravatar Jeff King1-0/+11
When upload-pack advertises the refs (either for a normal, non-stateless request, or for the initial contact in a stateless one), we call for_each_ref with the send_ref function as its callback. send_ref, in turn, calls mark_our_ref, which checks whether the ref is hidden, and sets OUR_REF or HIDDEN_REF on the object as appropriate. If it is hidden, mark_our_ref also returns "1" to signal send_ref that the ref should not be advertised. If we are not advertising refs, (i.e., the follow-up invocation by an http client to send its "want" lines), we use mark_our_ref directly as a callback to for_each_ref. Its marking does the right thing, but when it then returns "1" to for_each_ref, the latter interprets this as an error and stops iterating. As a result, we skip marking all of the refs that come lexicographically after it. Any "want" lines from the client asking for those objects will fail, as they were not properly marked with OUR_REF. To solve this, we introduce a wrapper callback around mark_our_ref which always returns 0 (even if the ref is hidden, we want to keep iterating). We also tweak the signature of mark_our_ref to exclude unnecessary parameters that were present only to conform to the callback interface. This should make it less likely for somebody to accidentally use it as a callback in the future. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

In "git log --decorate", you would see the commit header like this: commit ... (HEAD, jc/decorate-leaky-separator-color) where "commit ... (" is painted in color.diff.commit, "HEAD" in color.decorate.head, ", " in color.diff.commit, the branch name in color.decorate.branch and then closing ")" in color.diff.commit. If you wanted to paint the HEAD and local branch name in the same color as the body text (perhaps because cyan and green are too faint on a black-on-white terminal to be readable), you would not want to have to say [color "decorate"] head = black branch = black because that you would not be able to reuse same configuration on a white-on-black terminal. You would naively expect [color "decorate"] head = normal branch = normal to work, but unfortunately it does not. It paints the string "HEAD" and the branch name in the same color as the opening parenthesis or comma between the decoration elements. This is because the code forgets to reset the color after printing the "prefix" in its own color. It theoretically is possible that some people were expecting and relying on that the attribute set as the "diff.commit" color, which is used to draw these opening parenthesis and inter-item comma, is inherited by the drawing of branch names, but it is not how the coloring works everywhere else.

The rename code cannot handle an input where we have duplicate destinations (i.e., more than one diff_filepair in the queue with the same string in its pair->two->path). We end up allocating only one slot in the rename_dst mapping. If we fill in the diff_filepair for that slot, when we re-queue the results, we may queue that filepair multiple times. When the diff is finally flushed, the filepair is processed and free()d multiple times, leading to heap corruption. This situation should only happen when a tree diff sees duplicates in one of the trees (see the added test for a detailed example). Rather than handle it, the sanest thing is just to turn off rename detection altogether for the diff. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

We have a helper function test_ln_s_add that inserts a symbolic link into the index even if the file system does not support symbolic links. There is a small flaw in the emulation path: the added entry does not pick up stat information of the fake symbolic link from the file system, as a consequence, the index is not exactly the same as for the "regular" path (where symbolic links are available). To fix this, just call git update-index again. This flaw was revealed by the earlier change that tightened compare_diff_raw(), because a test case in t4008 depends on the correctly updated index.

2015-02-17daemon: sanitize incoming virtual hostnameLibravatar Jeff King1-0/+11
We use the daemon_avoid_alias function to make sure that the pathname the user gives us is sane. However, after applying that check, we might then interpolate the path using a string given by the server admin, but which may contain more untrusted data from the client. We should be sure to sanitize this data, as well. We cannot use daemon_avoid_alias here, as it is more strict than we need in requiring a leading '/'. At the same time, we can be much more strict here. We are interpreting a hostname, which should not contain slashes or excessive runs of dots, as those things are not allowed in DNS names. Note that in addition to cleansing the hostname field, we must check the "canonical hostname" (%CH) as well as the port (%P), which we take as a raw string. For the canonical hostname, this comes from an actual DNS lookup on the accessed IP, which makes it a much less likely vector for problems. But it does not hurt to sanitize it in the same way. Unfortunately we cannot test this case easily, as it would involve a custom hostname lookup. We do not need to check %IP, as it comes straight from inet_ntop, so must have a sane form.

2015-02-17t5570: test git-daemon's --interpolated-path optionLibravatar Jeff King1-0/+16
We did not test this at all; let's just give a basic sanity check that we can find a path based on virtual hosting, and that the downcase canonicalization works. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2015-02-16git-send-email.perl: support no- prefix with older GetOptionsLibravatar Kyle J. McKay1-5/+5
Only Perl version 5.8.0 or later is required, but that comes with an older Getopt::Long (2.32) that does not support the 'no-' prefix. Support for that was added in Getopt::Long version 2.33. Since the help only mentions the 'no-' prefix and not the 'no' prefix, add explicit support for the 'no-' prefix to support older GetOptions versions. Reported-by: Tom G.
