5 years agosubtree: fix the GIT_EXEC_PATH sanity check to work on Windows

subtree: fix the GIT_EXEC_PATH sanity check to work on Windows

In 22d550749361 (subtree: don't fuss with PATH, 2021-04-27), `git
subtree` was broken thoroughly on Windows.

The reason is that it assumes Unix semantics, where `PATH` is
colon-separated, and it assumes that `$GIT_EXEC_PATH:` is a verbatim
prefix of `$PATH`. Neither are true, the latter in particular because
`GIT_EXEC_PATH` is a Windows-style path, while `PATH` is a Unix-style
path list.

Let's make extra certain that `$GIT_EXEC_PATH` and the first component
of `$PATH` refer to different entities before erroring out.

We do that by using the `test <path1> -ef <path2>` command that verifies
that the inode of `<path1>` and of `<path2>` is the same.

Sadly, this construct is non-portable, according to
https://pubs.opengroup.org/onlinepubs/009695399/utilities/test.html.
However, it does not matter in practice because we still first look
whether `$GIT_EXEC_PREFIX` is string-identical to the first component of
`$PATH`. This will give us the expected result everywhere but in Git for
Windows, and Git for Windows' own Bash _does_ handle the `-ef` operator.

Just in case that we _do_ need to show the error message _and_ are
running in a shell that lacks support for `-ef`, we simply suppress the
error output for that part.

5 years agobitmaps: don't recurse into trees already in the bitmap
Jeff King [Mon, 14 Jun 2021 12:05:44 +0000 (08:05 -0400)] 
bitmaps: don't recurse into trees already in the bitmap

If an object is already mentioned in a reachability bitmap we are
building, then by definition so are all of the objects it can reach. We
have an optimization to stop traversing commits when we see they are
already in the bitmap, but we don't do the same for trees.

It's generally unavoidable to recurse into trees for commits not yet
covered by bitmaps (since most commits generally do have unique
top-level trees). But they usually have subtrees that are shared with
other commits (i.e., all of the subtrees the commit _didn't_ touch). And
some of those commits (and their trees) may be covered by the bitmap.

Usually this isn't _too_ big a deal, because we'll visit those subtrees
only once in total for the whole walk. But if you have a large number of
unbitmapped commits, and if your tree is big, then you may end up
opening a lot of sub-trees for no good reason.

We can use the same optimization we do for commits here: when we are
about to open a tree, see if it's in the bitmap (either the one we are
building, or the "seen" bitmap which covers the UNINTERESTING side of
the bitmap when doing a set-difference).

This works especially well because we'll visit all commits before
hitting any trees. So even in a history like:

  A -- B

if "A" has a bitmap on disk but "B" doesn't, we'll already have OR-ed in
the results from A before looking at B's tree (so we really will only
look at trees touched by B).

For most repositories, the timings produced by p5310 are unspectacular.
Here's linux.git:

  Test                         HEAD^             HEAD
  --------------------------------------------------------------------
  5310.4: simulated clone      6.00(5.90+0.10)   5.98(5.90+0.08) -0.3%
  5310.5: simulated fetch      2.98(5.45+0.18)   2.85(5.31+0.18) -4.4%
  5310.7: rev-list (commits)   0.32(0.29+0.03)   0.33(0.30+0.03) +3.1%
  5310.8: rev-list (objects)   1.48(1.44+0.03)   1.49(1.44+0.05) +0.7%

Any improvement there is within the noise (the +3.1% on test 7 has to be
noise, since we are not recursing into trees, and thus the new code
isn't even run). The results for git.git are likewise uninteresting.

But here are numbers from some other real-world repositories (that are
not public). This one's tree is comparable in size to linux.git, but has
~16k refs (and so less complete bitmap coverage):

  Test                         HEAD^               HEAD
  -------------------------------------------------------------------------
  5310.4: simulated clone      38.34(39.86+0.74)   33.95(35.53+0.76) -11.5%
  5310.5: simulated fetch      2.29(6.31+0.35)     2.20(5.97+0.41) -3.9%
  5310.7: rev-list (commits)   0.99(0.86+0.13)     0.96(0.85+0.11) -3.0%
  5310.8: rev-list (objects)   11.32(11.04+0.27)   6.59(6.37+0.21) -41.8%

And here's another with a very large tree (~340k entries), and a fairly
large number of refs (~10k):

  Test                         HEAD^               HEAD
  -------------------------------------------------------------------------
  5310.3: simulated clone      53.83(54.71+1.54)   39.77(40.76+1.50) -26.1%
  5310.4: simulated fetch      19.91(20.11+0.56)   19.79(19.98+0.67) -0.6%
  5310.6: rev-list (commits)   0.54(0.44+0.11)     0.51(0.43+0.07) -5.6%
  5310.7: rev-list (objects)   24.32(23.59+0.73)   9.85(9.49+0.36) -59.5%

This patch provides substantial improvements in these larger cases, and
have any drawbacks for smaller ones (the cost of the bitmap check is
quite small compared to an actual tree traversal).

Note that we have to add a version of revision.c's include_check
callback which handles non-commits. We could possibly consolidate this
into a single callback for all objects types, as there's only one user
of the feature which would need converted (pack-bitmap.c:should_include).
That would in theory let us avoid duplicating any logic. But when I
tried it, the code ended up much worse to read, with lots of repeated
"if it's a commit do this, otherwise do that". Having two separate
callbacks splits that naturally, and matches the existing split of
show_commit/show_object callbacks.

Some users have expressed interest in a more "batteries included" way of
building via CMake[1], and a big part of that is providing easier access
to tooling external tools.

A straightforward way to accomplish this is to make it as simple as
possible is to enable the generation of the compile_commands.json file,
which is supported by many tools such as: clang-tidy, clang-format,
sourcetrail, etc.

This does come with a small run-time overhead during the configuration
step (~6 seconds on my machine):

    Time to configure with CMAKE_EXPORT_COMPILE_COMMANDS=TRUE

    real    1m9.840s
    user    0m0.031s

    real    1m3.195s
    user    0m0.015s
    sys     0m0.015s

This seems like a small enough price to pay to make the project more
accessible to newer users.  Additionally there are other large projects
like llvm [2] which has had this enabled by default for >6 years at the
time of this writing, and no real negative consequences that I can find
with my search-skills.

NOTE: That the compile_commands.json is currently produced only when
using the Ninja and Makefile generators.  See The CMake documentation[3]
for more info.

using the Visual Studio generator which was not ideal because:

  - Not all users who want to use vcpkg use the Visual Studio
    generators.

  - Some versions of Visual Studio 2019 moved away from using the
    VS 2019  generator by default, making it impossible for Visual
    Studio to configure the project in the likely event that it couldn't
    find the dependencies.

  - Inexperienced users of CMake are very likely to get tripped up by
    the errors caused by a lack of vcpkg, making the above bullet point

5 years agobulk-checkin: make buffer reuse more obvious and safer
Andrzej Hunt [Thu, 10 Jun 2021 16:48:30 +0000 (16:48 +0000)] 
bulk-checkin: make buffer reuse more obvious and safer

ibuf can be reused for multiple iterations of the loop. Specifically:
deflate() overwrites s.avail_in to show how much of the input buffer
has not been processed yet - and sometimes leaves 'avail_in > 0', in
which case ibuf will be processed again during the loop's subsequent
iteration.

But if we declare ibuf within the loop, then (in theory) we get a new
(and uninitialised) buffer for every iteration. In practice, my compiler
seems to resue the same buffer - meaning that this code does work - but
it doesn't seem safe to rely on this behaviour. MSAN correctly catches
this issue - as soon as we hit the 's.avail_in > 0' condition, we end up
reading from what seems to be uninitialised memory.

Therefore, we move ibuf out of the loop, making this reuse safe.

See MSAN output from t1050-large below - the interesting part is the
ibuf creation at the end, although there's a lot of indirection before
we reach the read from unitialised memory:

5 years agoadd_pending_object_with_path(): work around "gcc -O3" complaint
Jeff King [Thu, 10 Jun 2021 13:06:43 +0000 (09:06 -0400)] 
add_pending_object_with_path(): work around "gcc -O3" complaint

When compiling with -O3, some gcc versions (10.2.1 here) complain about
an out-of-bounds subscript:

  revision.c: In function ‘do_add_index_objects_to_pending’:
  revision.c:321:22: error: array subscript [1, 2147483647] is outside array bounds of ‘char[1]’ [-Werror=array-bounds]
    321 |   if (0 < len && name[len] && buf.len)
        |                  ~~~~^~~~~

The "len" parameter here comes from calling interpret_branch_name(),
which intends to return the number of characters of "name" it parsed.

But the compiler doesn't realize this. It knows the size of the empty
string "name" passed in from do_add_index_objects_to_pending(), but it
has no clue that the "len" we get back will be constrained to "0" in
that case.

And I don't think the warning is telling us about some subtle or clever
bug. The implementation of interpret_branch_name() is in another file
entirely, and the compiler can't see it (you can even verify there is no
clever LTO going on by replacing it with "return 0" and still getting
the warning).

We can work around this by replacing our "did we hit the trailing NUL"
subscript dereference with a length check. We do not even have to pay
the cost for an extra strlen(), as we can pass our new length into
interpret_branch_name(), which was converting our "0" into a call to
strlen() anyway.

ll_union_merge(): rename path_unused parameter

The "path" parameter to ll_union_merge() is named "path_unused", since
we don't ourselves use it. But we do pass it to ll_xdl_merge(), which

to warning()). Let's rename it to correct this inaccuracy (both of the
other functions correctly do not call this "unused").

Note that we also pass drv_unused, but it truly is unused by the rest of

5 years agoll_union_merge(): pass name labels to ll_xdl_merge()
Jeff King [Thu, 10 Jun 2021 12:58:43 +0000 (08:58 -0400)] 
ll_union_merge(): pass name labels to ll_xdl_merge()

Since cd1d61c44f (make union merge an xdl merge favor, 2010-03-01), we
pass NULL to ll_xdl_merge() for the "name" labels of the ancestor, ours
and theirs buffers. We usually use these for annotating conflict markers
left in a file. For a union merge, these shouldn't matter; the point of
it is that we'd never leave conflict markers in the first place.

But there is one code path where we may dereference them: if the file
contents appear to be binary, ll_binary_merge() will give up and pass
them to warning() to generate a message for the user (that was true even
when cd1d61c44f was written, though the warning was in ll_xdl_merge()
back then).

That can result in a segfault, though on many systems (including glibc),
the printf routines will helpfully just say "(null)" instead. We can
extend our binary-union test in t6406 to check stderr, which catches the
problem on all systems.

This also fixes a warning from "gcc -O3". Unlike lower optimization
levels, it inlines enough to see that the NULL can make it to warning()
and complains:

5 years agoll_binary_merge(): handle XDL_MERGE_FAVOR_UNION
Jeff King [Thu, 10 Jun 2021 12:57:05 +0000 (08:57 -0400)] 
ll_binary_merge(): handle XDL_MERGE_FAVOR_UNION

Prior to commit a944af1d86 (merge: teach -Xours/-Xtheirs to binary
ll-merge driver, 2012-09-08), we always reported a conflict from
ll_binary_merge() by returning "1" (in the xdl_merge and ll_merge code,
this value is the number of conflict hunks). After that commit, we
report zero conflicts if the "variant" flag is set, under the assumption
that it is one of XDL_MERGE_FAVOR_OURS or XDL_MERGE_FAVOR_THEIRS.

But this gets confused by XDL_MERGE_FAVOR_UNION. We do not know how to
do a binary union merge, but erroneously report no conflicts anyway (and
just blindly use the "ours" content as the result).

Let's tighten our check to just the cases that a944af1d86 meant to
cover. This fixes the union case (which existed already back when that
commit was made), as well as future-proofing us against any other
variants that get added later.

Note that you can't trigger this from "git merge-file --union", as that
bails on binary files before even calling into the ll-merge machinery.
The test here uses the "union" merge attribute, which does erroneously
report a successful merge.

5 years agogitweb: use HEAD as secondary sort key in git_get_heads_list()
Greg Hurrell [Wed, 9 Jun 2021 19:28:06 +0000 (21:28 +0200)] 
gitweb: use HEAD as secondary sort key in git_get_heads_list()

The "heads" section on the gitweb summary page shows heads in
`-committerdate` order (ie. the most recently-modified ones at the
top), tie-breaking equal-dated refs using the implicit `refname` sort
fallback. This recency-based ordering appears in multiple places in the
UI, such as the project listing, the tags list, and even the
shortlog and log views.

Given two equal-dated refs, however, sorting the `HEAD` ref before
the non-`HEAD` ref provides more useful signal than merely sorting by
refname. For example, say we had "master" and "trunk" both pointing at
the same commit but "trunk" was `HEAD`, sorting "trunk" first helps
communicate its special status as the default branch that you'll check
out if you clone the repo.

Add `-HEAD` as a secondary sort key to the `git for-each-ref` call
in `git_get_heads_list()` to provide the desired behavior. The most
recently committed refs will appear first, but `HEAD`-ness will be used
as a tie-breaker. Note that `refname` is the implicit fallback sort key,
which means that two same-dated non-`HEAD` refs will continue to be
sorted in lexicographical order, as they are today.

diffcore-rename: avoid unnecessary strdup'ing in break_idx

that usage is always before any free'ing of the pairs (and thus the
strings in the pairs).  As such, there is no need to strdup these keys;
we can just reuse the existing strings as-is.

The merge logic doesn't make use of break detection, so this does not
affect the performance of any of my testcases.  It was just a minor
unrelated optimization noted in passing while looking at the code.

merge-ort: replace string_list_df_name_compare with faster alternative

Gathering accumulated times from trace2 output on the mega-renames
testcase, I saw the following timings (where I'm only showing a few
lines to highlight the portions of interest):

    10.120 : label:incore_nonrecursive
        4.462 : ..label:process_entries
           3.143 : ....label:process_entries setup
              2.988 : ......label:plist special sort

        2.604 : ..label:collect_merge_info
        2.018 : ..label:merge_start
        1.018 : ..label:renames

In the above output, note that the 4.462 seconds for process_entries was
split as 3.143 seconds for "process_entries setup" and 1.305 seconds for
"processing" (and a little time for other stuff removed from the
highlight).  Most of the "process_entries setup" time was spent on
"plist special sort" which corresponds to the following code:

    trace2_region_enter("merge", "plist special sort", opt->repo);
    plist.cmp = string_list_df_name_compare;
    string_list_sort(&plist);
    trace2_region_leave("merge", "plist special sort", opt->repo);

In other words, in a merge strategy that would be invoked by passing
"-sort" to either rebase or merge, sorting an array takes more time than
anything else.  Serves me right for naming my merge strategy this way.

Rewrite the comparison function in a way that does not require finding
out the lengths of the strings when comparing them.  While at it, tweak
the code for our specific case -- no need to handle a variety of modes,
for example.  The combination of these changes reduced the time spent in
"plist special sort" by ~25% in the mega-renames case.

For the testcases mentioned in commit 557ac0350d ("merge-ort: begin
performance work; instrument with trace2_region_* calls", 2020-10-28),
this change improves the performance as follows:

                            Before                  After
    no-renames:        5.622 s ±  0.059 s     5.235 s ±  0.042 s

mailinfo: use starts_with() when checking scissors

Existing checks for scissors characters using memcmp(3) never read past
the end of the line, because all substrings we are interested in are two
characters long, and the outer loop guarantees we have at least one
character.  So at most we will look at the NUL.

However, this is too subtle and may lead to bugs in code which copies
this behavior without realizing substring length requirement.  So use
starts_with() instead, which will stop at NUL regardless of the length
of the prefix.  Remove extra pair of parentheses while we are here.

parallel-checkout: avoid dash local bug in tests

Dash bug https://bugs.launchpad.net/ubuntu/+source/dash/+bug/139097
lets the shell erroneously perform field splitting on the expansion of a
command substitution during declaration of a local variable.  It causes
the parallel-checkout tests to fail e.g. when running them with
/bin/dash on MacOS 11.4, where they error out like this:

   ./t2080-parallel-checkout-basics.sh: 33: local: 0: bad variable name

That's because the output of wc -l contains leading spaces and the
returned number of lines is treated as another variable to declare, i.e.
as in "local workers= 0".

Work around it by enclosing the command substitution in quotes.

This can lead to test breakage, e.g., where "--progress" is used,

5 years agocat-file: handle trivial --batch format with --batch-all-objects
ZheNing Hu [Thu, 3 Jun 2021 16:29:25 +0000 (16:29 +0000)] 
cat-file: handle trivial --batch format with --batch-all-objects

The --batch code to print an object assumes we found out the type of
the object from calling oid_object_info_extended(). This is true for
the default format, but even in a custom format, we manually modify
the object_info struct to ask for the type.

This assumption was broken by 845de33a5b (cat-file: avoid noop calls
to sha1_object_info_extended, 2016-05-18). That commit skips the call
to oid_object_info_extended() entirely when --batch-all-objects is in
use, and the custom format does not include any placeholders that
require calling it.

Or when the custom format only include placeholders like %(objectname) or
%(rest), oid_object_info_extended() will not get the type of the object.

This results in an error when we try to confirm that the type didn't
change:

$ git cat-file --batch=batman --batch-all-objects
batman
fatal: object 000023961a0c02d6e21dc51ea3484ff71abf1c74 changed type!?

and also has other subtle effects (e.g., we'd fail to stream a blob,
since we don't realize it's a blob in the first place).

We can fix this by flipping the order of the setup. The check for "do
we need to get the object info" must come _after_ we've decided
whether we need to look up the type.

broken as a result of this change.
