* prepare_index(): declare return value to be (const char *)Michael Haggerty2014-10-011-2/+2
| | | | | | | | | | | Declare the return value to be const to make it clear that we aren't giving callers permission to write over the string that it points at. (The return value is the filename field of a struct lock_file, which can be used by a signal handler at any time and therefore shouldn't be tampered with.)

| * mailinfo: make ">From" in-body header check more robustJeff King2014-09-161-1/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit 81c5cf7 (mailinfo: skip bogus UNIX From line inside body, 2006-05-21), we have treated lines like ">From" in the body as headers. This makes "git am" work for people who erroneously paste the whole output from format-patch: From 12345abcd...fedcba543210 Mon Sep 17 00:00:00 2001 From: them Subject: [PATCH] whatever into their email body (assuming that an mbox writer then quotes "From" as ">From", as otherwise we would actually mailsplit on the in-body line). However, this has false positives if somebody actually has a commit body that starts with "From "; in this case we erroneously remove the line entirely from the commit message. We can make this check more robust by making sure the line actually looks like a real mbox "From" line. Inspect the line that begins with ">From " a more carefully to only skip lines that match the expected pattern (note that the datestamp part of the format-patch output is designed to be kept constant to help those who write magic(5) entries).

The reason is that the get_sha1() code path does not allow us to suppress this message. Pass the flags bitfield through get_sha1_with_context() so that read_ref_at() can suppress the message. Use get_sha1_with_context1() instead of get_sha1() in rev-parse so that the --quiet flag is honored. Signed-off-by: David Aguilar <davvid@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Any branch tips that are marked UNINTERESTING after it returns must be ancestors of that commit. As we iterate through the list of refs to show, we check item->commit->object.flags to see whether it was marked. This interacts badly with --verbose, which will do a separate walk to find the ahead/behind information for each branch. There are two bad things that can happen: 1. The ahead/behind walk may get the wrong results, because it can see a bogus UNINTERESTING flag leftover from the merge-filter walk. 2. We may omit some branches if their tips are involved in the ahead/behind traversal of a branch shown earlier. The ahead/behind walk carefully cleans up its commit flags, meaning it may also erase the UNINTERESTING flag that we expect to check later. We can solve this by moving the merge-filter state for each ref into its "struct ref_item" as soon as we finish the merge-filter walk. That fixes (2). Then we are free to clear the commit flags we used in the walk, fixing (1). Note that we actually do away with the matches_merge_filter helper entirely here, and inline it between the revision walk and the flag-clearing. This ensures that nobody accidentally calls it at the wrong time (it is only safe to check in that instant between the setting and clearing of the global flag).

The same information is fed from the standard input to pre/post-receive hooks instead to lift this limitation. It has been mandatory for these new style hooks to consume the update information fully from the standard input stream. Otherwise, they would risk killing the receive-pack process via SIGPIPE. If a hook does not want to look at all the information, it is easy to send its standard input to /dev/null (perhaps a niche use of hook might need to know only the fact that a push was made, without having to know what objects have been pushed to update which refs), and this has already been done by existing hooks that are written carefully. However, because there is no good way to consistently fail hooks that do not consume the input fully (a small push may result in a short update record that may fit within the pipe buffer, to which the receive-pack process may manage to write before the hook has a chance to exit without reading anything, which will not result in a death-by-SIGPIPE of receive-pack), it can lead to a hard to diagnose "once in a blue moon" phantom failure. Lift this "hooks must consume their input fully" mandate. A mandate that is not enforced strictly is not helping us to catch mistakes in hooks. If a hook has a good reason to decide the outcome of its operation without reading the information we feed it, let it do so as it pleases. Signed-off-by: Junio C Hamano <gitster@pobox.com>

For commits, there is a hack in place: we basically cache commit objects' buffers anyway, but the same is not true, say, for tag objects. By refactoring fsck_object() to take the object buffer and size as optional arguments -- optional, because we still fall back to the previous method to look at the cached commit objects if the caller passes NULL -- we prepare the machinery for the upcoming handling of tag objects. The assumption that such buffers are inherently NUL terminated is now wrong, of course, hence we pass the size of the buffer so that we can add a sanity check later, to prevent running past the end of the buffer.

However, it will not exit non-zero for any missing ref tips, meaning that a severely broken repository may still pass "git fsck && echo ok". The problem is that we use for_each_ref to iterate over the ref tips, which hides broken tips. It does at least print an error from the refs.c code, but fsck does not ever see the ref and cannot note the problem in its exit code. We can solve this by using for_each_rawref and noting the error ourselves. In addition to adding tests for this case, we add tests for all types of missing-object links (all of which worked, but which we were not testing).

When we resolve a particular delta, we flip its "real_type" field from OBJ_{REF,OFS}_DELTA to whatever the real type is. We assume that traversing the objects this way will visit each delta only once. This is correct for most packs; we visit the delta only when we process its base, and each object (and thus each base) appears only once. However, if a base object appears multiple times in the pack, we will try to resolve any deltas based on it once for each instance. We can detect this case by noting that a delta we are about to resolve has already had its real_type field flipped, and we already do so with an assert(). However, if multiple threads are in use, we may race with another thread on comparing and flipping the field. We need to synchronize the access. The right mechanism for doing this is a compare-and-swap (we atomically "claim" the delta for our own and find out whether our claim was successful). We can implement this in C by using a pthread mutex to protect the operation. This is not the fastest way of doing a compare-and-swap; many processors provide instructions for this, and gcc and other compilers provide builtins to access them. However, some experiments showed that lock contention does not cause a significant slowdown here. Adding c-a-s support for many compilers would increase the maintenance burden (and we would still end up including the pthread version as a fallback). Note that we only need to touch the OBJ_REF_DELTA codepath here. An OBJ_OFS_DELTA object points to its base using an offset, and therefore has only one base, even if another copy of that base object appears in the pack (we do still touch it briefly because the setting of real_type is factored out of resolve_data).

Using const pointers to getenv's return has two problems: 1. It is not guaranteed that the return value from getenv remains valid across multiple calls. 2. We do not know whether to free the values at the end, so we just leak them. We can solve both by duplicating the string returned by getenv().

This is shorter and easier to read, and should do a more careful parsing job. For example, the current parser could find the end-of-email right-bracket across a newline (for a malformed commit), and calculate a bogus gigantic length for the date (by using "eol - rb"). As a bonus, this also plugs a memory leak when we pull the date field from an existing commit (we still leak the name and email buffers, which will be fixed in a later commit).

This is a minor pain, as we have to take special precautions, and frequently end up copying the result into a strbuf or heap-allocated buffer anyway (for which we sometimes use strcpy!). Let's instead teach parse_date, datestamp, etc to write to a strbuf. The obvious downside is that we might need to perform a heap allocation where we otherwise would not need to. However, it turns out that the only two new allocations required are: 1. In test-date.c, where we don't care about efficiency. 2. In determine_author_info, which is not performance critical (and where the use of a strbuf will help later refactoring).

The output from "--date=iso" deviates from ISO 8601 in these ways: - a space instead of the `T` date/time delimiter - a space between time and time zone - no colon between hours and minutes of the time zone Add a strict ISO 8601 date format for displaying committer and author dates. Use the '%aI' and '%cI' format specifiers and add '--date=iso-strict' or '--date=iso8601-strict' date format names.

It would be useful if they could produce a repository that has a similar shape to its history and tree, but without leaking any information. This "anonymized" repository could then be shared with developers (assuming it still replicates the original problem). This patch implements an "--anonymize" option to fast-export, which generates a stream that can recreate such a repository. Producing a single stream makes it easy for the caller to verify that they are not leaking any useful information. You can get an overview of what will be shared by running a command like: git fast-export --anonymize --all | perl -pe 's/\d+/X/g' | sort -u | less which will show every unique line we generate, modulo any numbers (each anonymized token is assigned a number, like "User 0", and we replace it consistently in the output). In addition to anonymizing, this produces test cases that are relatively small (compared to the original repository) and fast to generate (compared to using filter-branch, or modifying the output of fast-export yourself). Here are numbers for git.git: $ time git fast-export --anonymize --all \ --tag-of-filtered-object=drop >output real 0m2.883s user 0m2.828s sys 0m0.052s $ gzip output $ ls -lh output.gz | awk '{print $5}' 2.9M Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

However, it can sometimes fail when pushing over http, because we have to spawn "git send-pack --stateless-rpc" to do the heavy lifting, and we pass each refspec on the command line. This can cause us to overflow the OS limits on the size of the command line for a large push. We can solve this by giving send-pack a --stdin option and using it from remote-curl. We already dealt with this on the fetch-pack side in 078b895 (fetch-pack: new --stdin option to read refs from stdin, 2012-04-02). The stdin option (and in particular, its use of packet-lines for stateless-rpc input) is modeled after that solution.
