t/perf: depend on perl JSON only when using --codespeedJeff King Tue, 23 Apr 2019 04:34:20 +0000 (00:34 -0400)

t/perf: depend on perl JSON only when using --codespeed

Commit 05eb1c37ed (perf/aggregate: implement codespeed JSON output,
2018-01-05) added a dependency on the perl JSON module to show output
from aggregate.perl, but we only need it when the user asks for
--codespeed output. While the module is pretty common, it's not part of
the base system, and this dependency can get in the way of producing the
default human-readable output.

Let's bump the "use" down to a "require" in the code path that needs it,
which will be interpreted at run-time instead of compile-time. People
not using "--codespeed" won't even load the module, and anybody using it
should see the same results (including the same perl error if they don't
have it).

Note that this skips the importing step, so we'll have to fully qualify
our function call. We could accomplish the same thing in other ways.
E.g., calling JSON->import() ourselves, or wrapping "use JSON" in an
eval. Since there's only one such call, this seems like the
least-magical way of doing it.

doc/ls-files: put nested list for "-t" option into... Jeff King Mon, 22 Apr 2019 15:15:41 +0000 (11:15 -0400)

doc/ls-files: put nested list for "-t" option into block

The description for the "-t" option contains a sub-list of all of the
possible file status outputs. But because of the newline separating that
list from the description paragraph, asciidoc treats the sub-list
entries as a continuation of the overall options list, rather than as
children of the "-t" description.

We could fix it by adding a "+" before the sub-list to connect it to the
rest of the "-t" text. But using a pair of "--" to delimit the block is
perhaps more readable, and may have better compatibility with
asciidoctor, as in 39a869b2f2 (Documentation/rev-list-options: wrap
--date=<format> block with "--", 2019-03-30).

The extra blank line comes from 5bc0e247c4 (Document ls-files -t as
semi-obsolete., 2010-07-28), but the problem actually seems older than
that. Before then, we did:

-t:: some text...
H:: cached
M:: unmerged
etc...

but asciidoc also treats that as one big list. So this problem seems to
have been around forever.

p5302: create the repo in each index-pack testJeff King Mon, 22 Apr 2019 21:19:52 +0000 (17:19 -0400)

p5302: create the repo in each index-pack test

The p5302 script runs "index-pack --stdin" in each timing test. It does
two things to try to get good timings:

1. we do the repo creation in a separate (non-timed) setup test, so
that our timing is purely the index-pack run

2. we use a separate repo for each test; this is important because the
presence of existing objects in the repo influences the result
(because we'll end up doing collision checks against them)

But this forgets one thing: we generally run each timed test multiple
times to reduce the impact of noise. Which means that repeats of each
test after the first will be subject to the collision slowdown from
point 2, and we'll generally just end up taking the first time anyway.

Instead, let's create the repo in the test (effectively undoing point
1). That does add a constant amount of extra work to each iteration, but
it's quite small compared to the actual effects we're interested in
measuring.

Makefile: dedup list of files obtained from ls-filesJunio C Hamano Sun, 21 Apr 2019 13:19:04 +0000 (22:19 +0900)

Makefile: dedup list of files obtained from ls-files

Since 33533975 ("Makefile: ask "ls-files" to list source files if
available", 2011-10-18), we optionally asked "ls-files" to list the
source files that ought to exist, as a faster approximation for
"find" on working tree files.

This works reasonably well, except that it ends up listing the same
path multiple times if the index is unmerged. Because the original
use of this construct was to name files to run etags over, and the
etags command happily takes the same filename multiple times without
causing any harm, there was no problem (other than perhaps spending
slightly more cycles, but who cares how fast the TAGS file gets
updated).

We however recently added a similar call to "ls-files" to list *.h
files, instead of using "find", in 92b88eba ("Makefile: use `git
ls-files` to list header files, if possible", 2019-03-04). In this
new use of "ls-files", the resulting list $(LIB_H) is used for,
among other things, generating the header files to run hdr-check
target, and the duplicate unfortunately becomes a true problem. It
causes $(MAKE) to notice that there are multiple %.hco targets and
complain.

Let the resulting list consumed by $(sort), which deduplicates,
to fix this.

clone: do faster object check for partial clones

For partial clones, doing a full connectivity check is wasteful; we skip
promisor objects (which, for a partial clone, is all known objects), and
enumerating them all to exclude them from the connectivity check can
take a significant amount of time on large repos.

At most, we want to make sure that we get the objects referred to by any
wanted refs. For partial clones, just check that these objects were
transferred.

worktree: update is_bare heuristicsJonathan Tan Fri, 19 Apr 2019 17:21:28 +0000 (10:21 -0700)

worktree: update is_bare heuristics

When "git branch -D <name>" is run, Git usually first checks if that
branch is currently checked out. But this check is not performed if the
Git directory of that repository is not at "<repo>/.git", which is the
case if that repository is a submodule that has its Git directory stored
as "super/.git/modules/<repo>", for example. This results in the branch
being deleted even though it is checked out.

This is because get_main_worktree() in worktree.c sets is_bare on a
worktree only using the heuristic that a repo is bare if the worktree's
path does not end in "/.git", and not bare otherwise. This is_bare code
was introduced in 92718b7438 ("worktree: add details to the worktree
struct", 2015-10-08), following a pre-core.bare heuristic. This patch
does 2 things:

- Teach get_main_worktree() to use is_bare_repository() instead,
introduced in 7d1864ce67 ("Introduce is_bare_repository() and
core.bare configuration variable", 2007-01-07) and updated in
e90fdc39b6 ("Clean up work-tree handling", 2007-08-01). This solves
the "git branch -D <name>" problem described above. However...

- If a repository has core.bare=1 but the "git" command is being run
from one of its secondary worktrees, is_bare_repository() returns
false (which is fine, since there is a worktree available). However,
treating the main worktree as non-bare when it is bare causes issues:
for example, failure to delete a branch from a secondary worktree
that is referred to by a main worktree's HEAD, even if that main
worktree is bare.

In order to avoid that, also check core.bare when setting is_bare. If
core.bare=1, trust it, and otherwise, use is_bare_repository().

rebase -i: run without forking rebase--interactive

When the builtin rebase starts an interactive rebase it parses the
options and then repackages them and forks
`rebase--interactive`. Separate the option parsing in
cmd_rebase__interactive() from the business logic to allow interactive
rebases can be run without forking `rebase__interactive` by calling
run_rebase_interactive() directly.

Starting interactive rebases without forking makes it easy to debug
the sequencer without worrying about attaching to child
processes. Ævar has also reported that some of the rebase perf tests
are 30% faster [1].

This patch also makes it easy to remove cmd_rebase__interactive() in
the future when git-legacy-rebase.sh and
git-rebase--preserve-merges.sh are retired.

sequencer: always discard index after checkout

As the checkout runs in a separate process our index will be out of date
so it should be discarded. The existing callers are not doing this
consistently so do it here to avoid the callers having to worry about
it.

This fixes some test failures that happen if do_interactive_rebase() is
called without forking rebase--interactive which we will implement
shortly. Running

git rebase -i master topic

starting on master created empty todo lists because all the commits in
topic were marked as cherry-picks. After topic was checked out in
prepare_branch_to_be_rebased() the working tree contained the contents
from topic but the index contained master and the cache entries were
still valid. This meant that diff_populate_filespec() which loads the
blobs when calculating patch-id's ended up reading the contents for
master from the working tree which actually contained topic.

untracked-cache: simplify parsing by dropping "len"Jeff King Thu, 18 Apr 2019 21:18:35 +0000 (17:18 -0400)

untracked-cache: simplify parsing by dropping "len"

The code which parses untracked-cache extensions from disk keeps a "len"
variable, which is the size of the string we are parsing. But since we
now have an "end of string" variable, we can just use that to get the
length when we need it. This eliminates the need to keep "len" up to
date (and removes the possibility of any errors where "len" and "eos"
get out of sync).

As a bonus, it means we are not storing a string length in an "int",
which is a potential source of overflows (though in this case it seems
fairly unlikely for that to cause any memory problems).

untracked-cache: simplify parsing by dropping "next"

When we parse an on-disk untracked cache, we have two pointers, "data"
and "next". As we parse, we point "next" to the end of an element, and
then later update "data" to match.

But we actually don't need two pointers. Each parsing step can just
update "data" directly from other variables we hold (and we don't have
to worry about bailing in an intermediate state, since any parsing
failure causes us to immediately discard "data" and return).

untracked-cache: be defensive about missing NULs in... Jeff King Thu, 18 Apr 2019 21:17:02 +0000 (17:17 -0400)

untracked-cache: be defensive about missing NULs in index

The on-disk format for the untracked-cache extension contains
NUL-terminated filenames. We parse these from the mmap'd file using
string functions like strlen(). This works fine in the normal case, but
if we see a malformed or corrupted index, we might read off the end of
our mmap.

Instead, let's use memchr() to find the trailing NUL within the bytes we
know are available, and return an error if it's missing.

Note that we can further simplify by folding another range check into
our conditional. After we find the end of the string, we set "next" to
the byte after the string and treat it as an error if there are no such
bytes left. That saves us from having to do a range check at the
beginning of each subsequent string (and works because there is always
data after each string). We can do both range checks together by
checking "!eos" (we didn't find a NUL) and "eos == end" (it was on the
last available byte, meaning there's nothing after). This replaces the
existing "next > end" checks.

Note also that the decode_varint() calls have a similar problem (we
don't even pass them "end"; they just keep parsing). These are probably
OK in practice since varints have a finite length (we stop parsing when
we'd overflow a uintmax_t), so the worst case is that we'd overflow into
reading the trailing bytes of the index.

t5304: add a test for pruning with bitmaps

Commit fde67d6896 (prune: use bitmaps for reachability traversal,
2019-02-13) uses bitmaps for pruning when they're available, but only
covers this functionality in the t/perf tests. This makes a kind of
sense, since the point is that the behaviour is indistinguishable before
and after the patch, just faster.

But since the bitmap code path is not exercised at all in the regular
test suite, it leaves us open to a regression where the behavior does in
fact change. The most thorough way to test that would be running the
whole suite with bitmaps enabled. But we don't yet have a way to do
that, and anyway it's expensive to do so. Let's at least add a basic
test that exercises this path and make sure we prune an object we should
(and not one that we shouldn't).

That would hopefully catch the most obvious breakages early.

Turn `git serve` into a test helperJohannes Schindelin Thu, 18 Apr 2019 13:16:51 +0000 (06:16 -0700)

Turn `git serve` into a test helper

The `git serve` built-in was introduced in ed10cb952d31 (serve:
introduce git-serve, 2018-03-15) as a backend to serve Git protocol v2,
probably originally intended to be spawned by `git upload-pack`.

However, in the version that the protocol v2 patches made it into core
Git, `git upload-pack` calls the `serve()` function directly instead of
spawning `git serve`; The only reason in life for `git serve` to survive
as a built-in command is to provide a way to test the protocol v2
functionality.

Meaning that it does not even have to be a built-in that is installed
with end-user facing Git installations, but it can be a test helper
instead.

Let's make it so.

check-docs: do not bother checking for legacy scripts' documentation

In the recent years, there has been a big push to convert more and more
of Git's commands that are implemented as scripts to built-ins written
in pure, portable C, for robustness, speed and portability.

One strategy that served us well is to convert those scripts
incrementally, starting by renaming the scripts to
`git-legacy-<command>`, then introducing a built-in that does nothing
else at first than checking the config setting `<command>.useBuiltin`
(which defaults to `false` at the outset) and handing off to the legacy
script if so asked.

Obviously, those `git-legacy-<command>` commands share the documentation
with the built-in `git-<command>`, and are not intended to be called
directly anyway. So let's not try to ensure that they are documented
separately from their built-in versions.

This issue was pointed out rightfully when running `make check-docs` on
Windows, where we do not yet have Unix sockets, and therefore the
`credential-cache` command is excluded (yet its documentation was built
and shipped).

Note: building the documentation via `make -C Documentation` leaves the
build system with no way to determine which commands have been
excluded. If called thusly, we gracefully fail to exclude their
documentation. Only when building the documentation via the top-level
Makefile will it get excluded properly, or after building

To do so, it compares the list of commands from that file to the

Commit 5e3548ef16 ("fetch: send server options when using protocol v2",
2018-04-24) taught "fetch" the ability to send server options when using
protocol v2, but not "clone". This ability is triggered by "-o" or
"--server-option".

Teach "clone" the same ability, except that because "clone" already
has "-o" for another parameter, teach "clone" only to receive
"--server-option".

Explain in the documentation, both for clone and for fetch, that server
handling of server options are server-specific. This is similar to
receive-pack's handling of push options - currently, they are just sent
to hooks to interpret as they see fit.

transport: die if server options are unsupportedJonathan Tan Fri, 12 Apr 2019 19:51:21 +0000 (12:51 -0700)

transport: die if server options are unsupported

Server options were added in commit 5e3548ef16 ("fetch: send server
options when using protocol v2", 2018-04-24), supported only for
protocol version 2. But if the user specifies server options, and the
protocol version being used doesn't support them, the server options are
silently ignored.

Teach any transport users to die instead in this situation, just like
how "push" dies if push options are provided when the server doesn't
support them.

ref-filter: use correct branch for %(push:track)Damien Robert Tue, 16 Apr 2019 12:16:46 +0000 (14:16 +0200)

ref-filter: use correct branch for %(push:track)

In ref-filter.c, when processing the atom %(push:track), the
ahead/behind values are computed using `stat_tracking_info` which refers
to the upstream branch.

Fix that by introducing a new flag `for_push` in `stat_tracking_info`
in remote.c, which does the same thing but for the push branch.
Update the few callers of `stat_tracking_info` to handle this flag. This
ensure that whenever we use this function in the future, we are careful
to specify is this should apply to the upstream or the push branch.

This bug was not detected in t/t6300-for-each-ref.sh because in the test
for push:track, both the upstream and the push branches were behind by 1
from the local branch. Change the test so that the upstream branch is
behind by 1 while the push branch is ahead by 1. This allows us to test
that %(push:track) refers to the correct branch.

This changes the expected value of some following tests (by introducing
new references), so update them too.

fix cherry-pick/revert status after commit

If the user commits a conflict resolution using `git commit` in the
middle of a sequence of cherry-picks/reverts then `git status` missed
the fact that a cherry-pick/revert is still in progress.

commit/reset: try to clean up sequencer state

When cherry-picking or reverting a sequence of commits and if the final
pick/revert has conflicts and the user uses `git commit` to commit the
conflict resolution and does not run `git cherry-pick --continue` then
the sequencer state is left behind. This can cause problems later. In my
case I cherry-picked a sequence of commits the last one of which I
committed with `git commit` after resolving some conflicts, then a while
later, on a different branch I aborted a revert which rewound my HEAD to
the end of the cherry-pick sequence on the previous branch. Avoid this
potential problem by removing the sequencer state if we're committing or
resetting the final pick in a sequence.
