Commit 685fbd3291 ("fetch-pack: perform a fetch using v2", 2018-03-15)
attempted to teach Git deepen-relative in protocol v2 (among other
things), but it didn't work:
(1) fetch-pack.c needs to emit "deepen-relative".
(2) upload-pack.c needs to ensure that the correct deepen_relative
variable is passed to deepen() (there are two - the static variable
and the one in struct upload_pack_data).
(3) Before deepen() computes the list of reachable shallows, it first
needs to mark all "our" refs as OUR_REF. v2 currently does not do
this, because unlike v0, it is not needed otherwise.
Fix all this and include a test demonstrating that it works now. For
(2), the static variable deepen_relative is also eliminated, removing a
source of confusion.

When fetching using protocol v2, the remote may send a "shallow-info"
section if the client is shallow. If so, Git as the client currently
takes the shallow file lock, even if the "shallow-info" section is
empty.
This is not a problem except that Git does not support taking the
shallow file lock after modifying the shallow file, because
is_repository_shallow() stores information that is never cleared. And
this take-after-modify occurs when Git does a tag-following fetch from a
shallow repository on a transport that does not support tag following
(since in this case, 2 fetches are performed).
To solve this issue, take the shallow file lock (and perform all other
shallow processing) only if the "shallow-info" section is non-empty;
otherwise, behave as if it were empty.
A full solution (probably, ensuring that any action of committing
shallow file locks also includes clearing the information stored by
is_repository_shallow()) would solve the issue without need for this
patch, but this patch is independently useful (as an optimization to
prevent writing a file in an unnecessary case), hence why I wrote it. I
have included a NEEDSWORK outlining the full solution.

When the scaffolding for protocol version 2 was initially added in

git log -p -G'support for protocol v2 not implemented yet' --full-diff --reverse v2.17.0..v2.20.0
Many of those scaffolding "die" placeholders were removed, but we
hadn't gotten around to fetch-pack yet.
The test here for "fetch refs from cmdline" is very minimal. There's
much better coverage when running the entire test suite under the WIP
GIT_TEST_PROTOCOL_VERSION=2 mode[1], we should ideally have better
coverage without needing to invoke a special test mode.

In the v2 protocol, upload-pack's advertisement has been moved to the
"ls-refs" command. That command does not respect hidden-ref config (like
transfer.hiderefs) at all, and advertises everything.
While there are some features that are not supported in v2 (e.g., v2
always allows fetching any sha1 without respect to advertisements), the
lack of this feature is not documented and is likely just a bug. Let's
make it work, as otherwise upgrading a server to a v2-capable git will
start exposing these refs that the repository admin has asked to remain
hidden.
Note that we assume we're operating on behalf of a fetch here, since
that's the only thing implemented in v2 at this point. See the in-code
comment. We'll have to figure out how this works when the v2 push
protocol is designed (both here in ls-refs, but also rejecting updates
to hidden refs).

This commit changes the way the indentation is handled to track the
visual size of the indentation rather than the characters in the
indentation. This has the benefit that any whitespace errors do not
interfer with the move detection (the whitespace errors will still be
highlighted according to --ws-error-highlight). During the discussion
of this feature there were concerns about the correct detection of
indentation for python. However those concerns apply whether or not
we're detecting moved lines so no attempt is made to determine if the

As part of an ongoing effort to make rebase have more uniform behavior,
modify the merge backend to behave like the interactive one, by
re-implementing it on top of the latter.
Interactive rebases are implemented in terms of cherry-pick rather than
the merge-recursive builtin, but cherry-pick also calls into the
recursive merge machinery by default and can accept special merge
strategies and/or special strategy options. As such, there really is
not any need for having both git-rebase--merge and
git-rebase--interactive anymore. Delete git-rebase--merge.sh and
instead implement it in builtin/rebase.c.
This results in a few deliberate but small user-visible changes:
* The progress output is modified (see t3406 and t3420 for examples)
* A few known test failures are now fixed (see t3421)
* bash-prompt during a rebase --merge is now REBASE-i instead of
REBASE-m. Reason: The prompt is a reflection of the backend in use;
this allows users to report an issue to the git mailing list with
the appropriate backend information, and allows advanced users to
know where to search for relevant control files. (see t9903)
testcase modification notes:
t3406: --interactive and --merge had slightly different progress output
while running; adjust a test to match the new expectation
t3420: these test precise output while running, but rebase--am,
rebase--merge, and rebase--interactive all were built on very
different commands (am, merge-recursive, cherry-pick), so the
tests expected different output for each type. Now we expect
--merge and --interactive to have the same output.
t3421: --interactive fixes some bugs in --merge! Wahoo!
t9903: --merge uses the interactive backend so the prompt expected is
now REBASE-i.

Uninitialized submodules have nothing valueable for us to be worried

continue in this case so that people can still use multiple worktrees
on repos with optional submodules that are never populated, like
sha1collisiondetection in git.git when checked out by doc-diff script.
Note that for "worktree remove", it is possible that a user
initializes a submodule (*), makes some commits (but not push), then
deinitializes it. At that point, the submodule is unpopulated, but the
precious new commits are still in
$GIT_COMMON_DIR/worktrees/<worktree>/modules/<submodule>
directory and we should not allow removing the worktree or we lose
those commits forever. The new directory check is added to prevent
this.
(*) yes they are screwed anyway by doing this since "git submodule"

Unfortunately, we have a few flaky tests, whose failures tend to be
hard to reproduce. We've found that the best we can do to reproduce
such a failure is to run the test script repeatedly while the machine
is under load, and wait in the hope that the load creates enough
variance in the timing of the test's commands that a failure is
evenually triggered. I have a command to do that, and I noticed that
two other contributors have rolled their own scripts to do the same,
all choosing slightly different approaches.
To help reproduce failures in flaky tests, introduce the '--stress'
option to run a test script repeatedly in multiple parallel jobs until
one of them fails, thereby using the test script itself to increase
the load on the machine.
The number of parallel jobs is determined by, in order of precedence:
the number specified as '--stress=<N>', or the value of the
GIT_TEST_STRESS_LOAD environment variable, or twice the number of
available processors (as reported by the 'getconf' utility), or 8.
Make '--stress' imply '--verbose -x --immediate' to get the most
information about rare failures; there is really no point in spending
all the extra effort to reproduce such a failure, and then not know
which command failed and why.
To prevent the several parallel invocations of the same test from
interfering with each other:
- Include the parallel job's number in the name of the trash
directory and the various output files under 't/test-results/' as
a '.stress-<Nr>' suffix.
- Add the parallel job's number to the port number specified by the
user or to the test number, so even tests involving daemons
listening on a TCP socket can be stressed.
- Redirect each parallel test run's verbose output to
't/test-results/$TEST_NAME.stress-<nr>.out', because dumping the
output of several parallel running tests to the terminal would
create a big ugly mess.
For convenience, print the output of the failed test job at the end,
and rename its trash directory to end with the '.stress-failed'
suffix, so it's easy to find in a predictable path (OTOH, all absolute
paths recorded in the trash directory become invalid; we'll see
whether this causes any issues in practice). If, in an unlikely case,
more than one jobs were to fail nearly at the same time, then print
the output of all failed jobs, and rename the trash directory of only
the last one (i.e. with the highest job number), as it is the trash
directory of the test whose output will be at the bottom of the user's
terminal.
Based on Jeff King's 'stress' script.

Several test scripts run daemons like 'git-daemon' or Apache, and
communicate with them through TCP sockets. To have unique ports where
these daemons are accessible, the ports are usually the number of the
corresponding test scripts, unless the user overrides them via
environment variables, and thus all those tests and test libs contain
more or less the same bit of one-liner boilerplate code to find out
the port. The last patch in this series will make this a bit more
complicated.
Factor out finding the port for a daemon into the common helper
function 'test_set_port' to avoid repeating ourselves.
Take special care of test scripts with "low" numbers:
- Test numbers below 1024 would result in a port that's only usable
as root, so set their port to '10000 + test-nr' to make sure it
doesn't interfere with other tests in the test suite. This makes
the hardcoded port number in 't0410-partial-clone.sh' unnecessary,
remove it.
- The shell's arithmetic evaluation interprets numbers with leading
zeros as octal values, which means that test number below 1000 and
containing the digits 8 or 9 will trigger an error. Remove all
leading zeros from the test numbers to prevent this.
Note that the 'git p4' tests are unlike the other tests involving
daemons in that:
- 'lib-git-p4.sh' doesn't use the test's number for unique port as
is, but does a bit of additional arithmetic on top [1].
- The port is not overridable via an environment variable.
With this patch even 'git p4' tests will use the test's number as
default port, and it will be overridable via the P4DPORT environment
variable.
[1] Commit fc00233071 (git-p4 tests: refactor and cleanup, 2011-08-22)
introduced that "unusual" unique port computation without
explaining why it was necessary (as opposed to simply using the
test number as is). It seems to be just unnecessary complication,
and in any case that commit came way before the "test nr as unique
port" got "standardized" for other daemons in commits c44132fcf3
(tests: auto-set git-daemon port, 2014-02-10), 3bb486e439 (tests:

'test-lib.sh' looks for the presence of certain options like '--tee'
and '--verbose-log', so it can execute the test script again to save
its standard output and error. It looks for '--valgrind' as well, to
set up some Valgrind-specific stuff. These all happen before the
actual option parsing loop, and the conditions looking for these
options look a bit odd, too. They are not completely correct, either,
because in a bogus invocation like './t1234-foo.sh -r --tee' they
recognize '--tee', although it should be handled as the required
argument of the '-r' option. This patch series will add two more
options to look out for early, and, in addition, will have to extract
these options' stuck arguments (i.e. '--opt=arg') as well.
So let's move the option parsing loop and the couple of related
conditions following it earlier in 'test-lib.sh', before the place
where the test script is executed again for '--tee' and its friends.

effecively destroying "$@" by the end of the option parsing. Not
good.
As a preparatory step, turn that option parsing loop into a 'for opt

options, and taking extra care to handle the '-r' option's required
argument (or the lack thereof).

Right now if a test script receives SIGTERM or SIGHUP (e.g., because a
test was hanging and the user 'kill'-ed it or simply closed the
terminal window the test was running in), the shell exits immediately.
This can be annoying if the test script did any global setup, like
starting apache or git-daemon, as it will not have an opportunity to
clean up after itself. A subsequent run of the test won't be able to
start its own daemon, and will either fail or skip the tests.
Instead, let's trap SIGTERM and SIGHUP as well to make sure we do a
clean shutdown, and just chain it to a normal exit (which will trigger
any cleanup).

This condition uses non-portable shell array accesses to easily get
Bash's major and minor version number. This didn't seem to be
problematic, because the simple commands expanding those array
accesses are only executed when the test script is actually run with
Bash. When run with Dash, the only shell I have at hand that doesn't
support shell arrays, there are no issues, as it apparently skips
right over the non-executed simple commands without noticing the
non-supported constructs.
Alas, it has been reported that NetBSD's /bin/sh does complain about
them:
./test-lib.sh: 327: Syntax error: Bad substitution
where line 327 contains the first ${BASH_VERSINFO[0]} array access.
To my understanding both shells are right and conform to POSIX,
because the standard allows both behaviors by stating the following
under '2.8.1 Consequences of Shell Errors' [3]:
"An expansion error is one that occurs when the shell expansions
define in wordexp are carried out (for example, "${x!y}", because
'!' is not a valid operator); an implementation may treat these as
syntax errors if it is able to detect them during tokenization,
rather than during expansion."
Avoid this issue with NetBSD's /bin/sh (and potentially with other,
less common shells) by hiding the shell array syntax behind 'eval'
that is only executed with Bash.

should complete 'test.txt', but nothing comes. The both problems will be
resolved by dequoting paths.
__git_complete_revlist_file() passes arguments to __gitcomp_nl() where
the first one is a list something like:
abc def/Z
foo bar.txt Z
where Z is the mark of the EOL.
- The trailing space of blob in __git ls-tree | sed.
It makes the completion results become:
git show HEAD:foo\ bar.txt\ <CURSOR>
So git will try to find a file named 'foo bar.txt ' instead.
- The trailing slash of tree in __git ls-tree | sed.
It makes the completion results on zsh become:
git show HEAD:abc\ def/ <CURSOR>
So that the last space on command like should be removed on zsh to
complete filenames under 'abc def/'.

In the Git pack protocol definition, an error packet may appear only in
a certain context. However, servers can face a runtime error (e.g. I/O
error) at an arbitrary timing. This patch changes the protocol to allow
an error packet to be sent instead of any packet.
Without this protocol spec change, when a server cannot process a
request, there's no way to tell that to a client. Since the server
cannot produce a valid response, it would be forced to cut a connection
without telling why. With this protocol spec change, the server can be
more gentle in this situation. An old client may see these error packets
as an unexpected packet, but this is not worse than having an unexpected
EOF.
Following this protocol spec change, the error packet handling code is
moved to pkt-line.c. Implementation wise, this implementation uses
pkt-line to communicate with a subprocess. Since this is not a part of
Git protocol, it's possible that a packet that is not supposed to be an
error packet is mistakenly parsed as an error packet. This error packet
handling is enabled only for the Git pack protocol parsing code
considering this.

Reimplement the `get_terms` and `bisect_terms` shell function in C and
add `bisect-terms` subcommand to `git bisect--helper` to call it from
git-bisect.sh .
Using `--bisect-terms` subcommand is a temporary measure to port shell
function in C so as to use the existing test suite. As more functions
are ported, this subcommand will be retired but its implementation will
be called by some other methods.
Also use error() to report "no terms defined" and accordingly change the
test in t6030.
We need to use PARSE_OPT_KEEP_UNKNOWN here to allow for parameters that
look like options (e.g --term-good) but should not be parsed by
cmd_bisect__helper(). This change is safe because all other cmdmodes have
strict argc checks already.

Ever since commit 3f213981e4 ("add tests for rebasing merged history",
2013-06-06), t3425 has had tests which included the rebasing of merged
history and whose order of applied commits was checked. Unfortunately,
the tests expected different behavior depending on which backend was in
use. Implementing these checks was the following four lines (including
the TODO message) which were repeated verbatim three times in t3425:
#TODO: make order consistent across all flavors of rebase
test_run_rebase success 'e n o' ''
test_run_rebase success 'e n o' -m
test_run_rebase success 'n o e' -i
As part of the effort to reduce differences between the rebase backends
so that users get more uniform behavior, let's define the correct
behavior and modify the different backends so they all get the right
answer. It turns out that the difference in behavior here is entirely
due to topological sorting; since some backends require topological
sorting (particularly when --rebase-merges is specified), require it for
all modes. Modify the am and merge backends to implement this.
Performance Considerations:
I was unable to measure any appreciable performance difference with this
change. Trying to control the run-to-run variation was difficult; I
eventually found a headless beefy box that I could ssh into, which
seemed to help. Using git.git, I ran the following testcase:
$ git reset --hard v2.20.0-rc1~2
$ time git rebase --quiet v2.20.0-rc0~16
I first ran once to warm any disk caches, then ran five subsequent runs
and recorded the times of those five. I observed the following results
for the average time:
Before this change:
"real" timing: 1.340s (standard deviation: 0.040s)
"user" timing: 1.050s (standard deviation: 0.041s)
"sys" timing: 0.270s (standard deviation: 0.011s)
After this change:
"real" timing: 1.327s (standard deviation: 0.065s)
"user" timing: 1.031s (standard deviation: 0.061s)
"sys" timing: 0.280s (standard deviation: 0.014s)
Measurements aside, I would expect the timing for walking revisions to
be dwarfed by the work involved in creating and applying patches, so
this isn't too surprising. Further, while somewhat counter-intuitive,
it is possible that turning on topological sorting is actually a
performance improvement: by way of comparison, turning on --topo-order
made fast-export faster (see
https://public-inbox.org/git/20090211135640.GA19600@coredump.intra.peff.net/).

The post-rewrite hook is supposed to be invoked for each rewritten
commit. The fact that a commit was selected and processed by the rebase
operation (even though when we hit an error a user said it had no more
useful changes), suggests we should write an entry for it. In
particular, let's treat it as an empty commit trivially squashed into
its parent.
This brings the rebase--am and rebase--merge backends in sync with the
behavior of the interactive rebase backend.

The post-rewrite hook is documented as being invoked by commands that
rewrite commits such as commit --amend and rebase, and that it will
be called for each rewritten commit.
Apparently, the three backends handled --skip'ed commits differently:
am: treat the skipped commit as though it weren't rewritten
merge: same as 'am' backend
interactive: treat skipped commits as having been rewritten to empty
(view them as an empty fixup to their parent)
For now, just add a testcase documenting the different behavior (use
--keep to force usage of the interactive machinery even though we have
no empty commits). A subsequent commit will remove the inconsistency in
--skip handling.

t5570 being racy has been reported twice separately on the mailing
list [*1*, *2*].
To make the test race proof, we'd either have to introduce another
fifo the test snippet is waiting on, or somehow convincing "cat" to
flush (and let us know when it has). Which really implies killing the
daemon, and wait()ing on cat to process the EOF and exit. And that
makes the tests a lot more expensive if we have to start the daemon
for each snippet.
As this is a test for a relatively minor fix (according to the author)
in 19136be3f8 ("daemon: fix off-by-one in logging extended
attributes", 2018-01-24), drop it to avoid this racyness. It doesn't
seem worth making the test code much more complex, or slowing down all
tests just to keep this one.

it was not completely independent of the_repository, as the previous

To ensure we're not accessing the_repository by accident, we'd ideally
assign NULL to the_repository to trigger a segfault on access.
We currently have a temporary hack in cache.h, which relies on
the_hash_algo (which is a short form of the_repository->hash_algo) to
be set, so we cannot do that. The next best thing is to set all fields of
the_repository to 0, so any accidental access is more likely to be found.

A regression for cygwin users was introduced with commit 05b458c,
"real_path: resolve symlinks by hand".
In the the commit message we read:
The current implementation of real_path uses chdir() in order to resolve
symlinks. Unfortunately this isn't thread-safe as chdir() affects a
process as a whole...
The old (and non-thread-save) OS calls chdir()/pwd() had been
replaced by a string operation.
The cygwin layer "knows" that "C:\cygwin" is an absolute path,
but the new string operation does not.
"git clone <url> C:\cygwin\home\USER\repo" fails like this:
fatal: Invalid path '/home/USER/repo/C:\cygwin\home\USER\repo'
The solution is to implement has_dos_drive_prefix(), skip_dos_drive_prefix()
is_dir_sep(), offset_1st_component() and convert_slashes() for cygwin
in the same way as it is done in 'Git for Windows' in compat/mingw.[ch]
Extract the needed code into compat/win32/path-utils.[ch] and use it
for cygwin as well.

The -G<regex> option of log looks for the differences whose patch text
contains added/removed lines that match regex.
Currently -G looks also into patches of binary files (which
according to [1]) is binary as well.
This has a couple of issues:
- It makes the pickaxe search slow. In a proprietary repository of the
author with only ~5500 commits and a total .git size of ~300MB
searching takes ~13 seconds
$time git log -Gwave > /dev/null
real 0m13,241s
user 0m12,596s
sys 0m0,644s
whereas when we ignore binary files with this patch it takes ~4s
$time ~/devel/git/git log -Gwave > /dev/null
real 0m3,713s
user 0m3,608s
sys 0m0,105s
which is a speedup of more than fourfold.
- The internally used algorithm for generating patch text is based on
xdiff and its states in [1]
> The output format of the binary patch file is proprietary
> (and binary) and it is basically a collection of copy and insert
> commands [..]
which means that the current format could change once the internal
algorithm is changed as the format is not standardized. In addition
the git binary patch format used for preparing patches for git apply
is *different* from the xdiff format as can be seen by comparing

When a submodule is deinit'd, the working tree is gone, so the setting of
core.worktree is bogus. Unset it. As we covered the only other case in
which a submodule loses its working tree in the earlier step
(i.e. switching branches of top-level project to move to a commit that did
not have the submodule), this makes the code always maintain
core.worktree correctly unset when there is no working tree
for a submodule.
This re-introduces 984cd77ddb (submodule deinit: unset core.worktree,
2018-06-18), which was reverted as part of f178c13fda (Revert "Merge

When a submodules work tree is removed, we should unset its core.worktree
setting as the worktree is no longer present. This is not just in line
with the conceptual view of submodules, but it fixes an inconvenience
for looking at submodules that are not checked out:
git clone --recurse-submodules git://github.com/git/git && cd git &&
git checkout --recurse-submodules v2.13.0
git -C .git/modules/sha1collisiondetection log
fatal: cannot chdir to '../../../sha1collisiondetection': \
No such file or directory
With this patch applied, the final call to git log works instead of dying
in its setup, as the checkout will unset the core.worktree setting such
that following log will be run in a bare repository.
This patch covers all commands that are in the unpack machinery, i.e.
checkout, read-tree, reset. A follow up patch will address
"git submodule deinit", which will also make use of the new function
submodule_unset_core_worktree(), which is why we expose it in this patch.
This patch was authored as 4fa4f90ccd (submodule: unset core.worktree if
no working tree is present, 2018-06-12), which was reverted as part of
f178c13fda (Revert "Merge branch 'sb/submodule-core-worktree'",
2018-09-07). The revert was needed as the nearby commit e98317508c
(submodule: ensure core.worktree is set after update, 2018-06-18) is
faulty and at the time of 7e25437d35 (Merge branch
'sb/submodule-core-worktree', 2018-07-18) we could not revert the faulty
commit only, as they were depending on each other: If core.worktree is
unset, we have to have ways to ensure that it is set again once
the working tree reappears again.
Now that 4d6d6ef1fc (Merge branch 'sb/submodule-update-in-c', 2018-09-17),
specifically 74d4731da1 (submodule--helper: replace
connect-gitdir-workingtree by ensure-core-worktree, 2018-08-13) is
present, we already check and ensure core.worktree is set when
populating a new work tree, such that we can re-introduce the commits
that unset core.worktree when removing the worktree.

Currently when git-fetch is asked to recurse into submodules, it dispatches
a plain "git-fetch -C <submodule-dir>" (with some submodule related options
such as prefix and recusing strategy, but) without any information of the
remote or the tip that should be fetched.
But this default fetch is not sufficient, as a newly fetched commit in
the superproject could point to a commit in the submodule that is not
in the default refspec. This is common in workflows like Gerrit's.
When fetching a Gerrit change under review (from refs/changes/??), the
commits in that change likely point to submodule commits that have not
been merged to a branch yet.
Fetch a submodule object by id if the object that the superproject
points to, cannot be found. For now this object is fetched from the
'origin' remote as we defer getting the default remote to a later patch.
A list of new submodule commits are already generated in certain
conditions (by check_for_new_submodule_commits()); this new feature
invokes that function in more situations.
The submodule checks were done only when a ref in the superproject
changed, these checks were extended to also be performed when fetching
into FETCH_HEAD for completeness, and add a test for that too.

When constructing a struct repository for a submodule for some revision
of the superproject where the submodule is not contained in the index,
it may not be present in the working tree currently either. In that
situation giving a 'path' argument is not useful. Upgrade the
repo_submodule_init function to take a struct submodule instead.
The submodule struct can be obtained via submodule_from_{path, name} or
an artificial submodule struct can be passed in.
While we are at it, rename the repository struct in the repo_submodule_init
function, which is to be initialized, to a name that is not confused with
the struct submodule as easily. Perform such renames in similar functions
as well.
Also move its documentation into the header file.

Commit d8981c3f88 ("format-patch: do not let its diff-options affect
--range-diff", 2018-11-30) taught `show_range_diff()` to accept a
NULL-pointer as an indication that it should use its own "reasonable
default". That fixed a regression from a5170794 ("Merge branch
'ab/range-diff-no-patch'", 2018-11-18), but unfortunately it introduced
a regression of its own.
In particular, it means we forget the `file` member of the diff options,
so rather than placing a range-diff in the cover-letter, we write it to
stdout. In order to fix this, rewrite the two callers adjusted by
d8981c3f88 to instead create a "dummy" set of diff options where they
only fill in the fields we absolutely require, such as output file and
color.
Modify and extend the existing tests to try and verify that the right
contents end up in the right place.
Don't revert `show_range_diff()`, i.e., let it keep accepting NULL.
Rather than removing what is dead code and figuring out it isn't

t0061 creates a script with an unlikely name in the current
directory and asks the run_command() API to run it without an
explicit path, expecting that the script does *not* get run. This
obviously would not work if the $PATH does contain such an element.
Check if the running shell picks up the script without an explicit
path to it, and skip the test when it does, as the run_command() API
should also run the script in such an (insane) environment.

When rebasing to a commit history that has no common commits with the
current branch, there is no merge base. In diffstat mode, this means
that we cannot compare to the merge base, but we have to compare to the
empty tree instead.
Also, if running in verbose diffstat mode, we should not output
Changes from <merge-base> to <onto>
as that does not make sense without any merge base.
Note: neither scripted nor built-in versoin of `git rebase` were
prepared for this situation well. We use this opportunity not only to
fix the bug(s), but also to make both versions' output consistent in
this instance. And add a regression test to keep this working in all
eternity.

The scripted version of "rebase" honored the `GIT_REFLOG_ACTION`,
and some automation scripts expected the reflog entries to be
prefixed with "rebase -i", not "rebase", after running "rebase -i".
This regressed in the reimplementation in C.
Fix that, and add a regression test, both with `GIT_REFLOG_ACTION`
set and unset.
Note: the reflog message for "rebase finished" did *not* honor
GIT_REFLOG_ACTION, and as we are very late in the v2.20.0-rcN phase,
we leave that bug for later (as it seems that that bug has been with

Test scripts checking 'git daemon' stop the daemon with a TERM signal,
and the 'stop_git_daemon' helper checks the daemon's exit status to
make sure that it indeed died because of that signal.
This check is bogus since 03c39b3458 (t/lib-git-daemon: use
test_match_signal, 2016-06-24), for two reasons:
- Right after killing 'git daemon', 'stop_git_daemon' saves its exit
status in a variable, but since 03c39b3458 the condition checking
the exit status looks at '$?', which at this point is not the exit
status of 'git daemon', but that of the variable assignment, i.e.
it's always 0.
- The unexpected exit status should abort the whole test script with
'error', but it doesn't, because 03c39b3458 forgot to negate
'test_match_signal's exit status in the condition.
This patch fixes both issues.

clone: fix colliding file detection on APFS
Commit b878579ae7 (clone: report duplicate entries on case-insensitive
filesystems - 2018-08-17) adds a warning to user when cloning a repo
with case-sensitive file names on a case-insensitive file system. The
"find duplicate file" check was doing by comparing inode number (and
only fall back to fspathcmp() when inode is known to be unreliable
because fspathcmp() can't cover all case folding cases).
The inode check is very simple, and wrong. It compares between a
32-bit number (sd_ino) and potentially a 64-bit number (st_ino). When
an inode is larger than 2^32 (which seems to be the case for APFS), it
will be truncated and stored in sd_ino, but comparing with itself will
fail.
As a result, instead of showing a pair of files that have the same
name, we show just one file (marked before the beginning of the
loop). We fail to find the original one.
The fix could be just a simple type cast (*)
dup->ce_stat_data.sd_ino == (unsigned int)st->st_ino
but this is no longer a reliable test, there are 4G possible inodes
that can match sd_ino because we only match the lower 32 bits instead
of full 64 bits.
There are two options to go. Either we ignore inode and go with
fspathcmp() on Apple platform. This means we can't do accurate inode
check on HFS anymore, or even on APFS when inode numbers are still
below 2^32.
Or we just to to reduce the odds of matching a wrong file by checking
more attributes, counting mostly on st_size because st_xtime is likely
the same. This patch goes with this direction, hoping that false
positive chances are too small to be seen in practice.
While at there, enable the test on Cygwin (verified working by Ramsay
Jones)
(*) this is also already done inside match_stat_data()

Since 3b1d9e04 (eoie: add End of Index Entry (EOIE) extension,
2018-10-10) Git defaults to writing the new EOIE section when writing
out an index file. Usually that is a good thing because it improves
threaded performance, but when a Git repository is shared with older
versions of Git, it produces a confusing warning:
$ git status
ignoring EOIE extension
HEAD detached at 371ed0defa
nothing to commit, working tree clean
Let's introduce the new index extension more gently. First we'll roll
out the new version of Git that understands it, and then once
sufficiently many users are using such a version, we can flip the
default to writing it by default.
Introduce a '[index] recordEndOfIndexEntries' configuration variable
to allow interested users to benefit from this index extension early.

The 'test_cmp_rev' helper is merely a wrapper around 'test_cmp'
checking the output of two 'git rev-parse' commands, which means that
its output on failure is not particularly informative, as it's
basically two OIDs with a bit of extra clutter of the diff header, but
without any indication of which two revisions have caused the failure:
--- expect.rev 2018-11-17 14:02:11.569747033 +0000
+++ actual.rev 2018-11-17 14:02:11.569747033 +0000

It also pollutes the test repo with these two intermediate files,
though that doesn't seem to cause any complications in our current
tests (meaning that I couldn't find any tests that have to work around
the presence of these files by explicitly removing or ignoring them).
Enhance 'test_cmp_rev' to provide a more useful output on failure with
less clutter:
error: two revisions point to different objects:
'HEAD^': d79ce1670bdcb76e6d1da2ae095e890ccb326ae9
'extra': 139b20d8e6c5b496de61f033f642d0e3dbff528d
Doing so is more convenient when storing the OIDs outputted by 'git
rev-parse' in a local variable each, which, as a bonus, won't pollute
the repository with intermediate files.
While at it, also ensure that 'test_cmp_rev' is invoked with the right
number of parameters, namely two.

Some of the functions in our test library check that they were invoked
properly with conditions like this:
test "$#" = 2 ||
error "bug in the test script: not 2 parameters to test-expect-success"
If this particular condition is triggered, then 'error' will abort the
whole test script with a bold red error message [1] right away.
However, under certain circumstances the test script will be aborted
completely silently, namely if:
- a similar condition in a test helper function like
'test_line_count' is triggered,
- which is invoked from the test script's "main" shell [2],
- and the test script is run manually (i.e. './t1234-foo.sh' as
opposed to 'make t1234-foo.sh' or 'make test') [3]
- and without the '--verbose' option,
because the error message is printed from within 'test_eval_', where
standard output is redirected either to /dev/null or to a log file.
The only indication that something is wrong is that not all tests in
the script are executed and at the end of the test script's output
there is no "# passed all N tests" message, which are subtle and can
easily go unnoticed, as I had to experience myself.
Send these "bug in the test script" error messages directly to the
test scripts standard error and thus to the terminal, so those bugs
will be much harder to overlook. Instead of updating all ~20 such
'error' calls with a redirection, let's add a BUG() function to
'test-lib.sh', wrapping an 'error' call with the proper redirection
and also including the common prefix of those error messages, and
convert all those call sites [4] to use this new BUG() function
instead.
[1] That particular error message from 'test_expect_success' is
printed in color only when running with or without '--verbose';
with '--tee' or '--verbose-log' the error is printed without
color, but it is printed to the terminal nonetheless.
[2] If such a condition is triggered in a subshell of a test, then
'error' won't be able to abort the whole test script, but only the
subshell, which in turn causes the test to fail in the usual way,
indicating loudly and clearly that something is wrong.
[3] Well, 'error' aborts the test script the same way when run
manually or by 'make' or 'prove', but both 'make' and 'prove' pay
attention to the test script's exit status, and even a silently
aborted test script would then trigger those tools' usual
noticable error messages.
[4] Strictly speaking, not all those 'error' calls need that
redirection to send their output to the terminal, see e.g.
'test_expect_success' in the opening example, but I think it's
better to be consistent.

a path is matched. This is done after path matching since we have lots
of optimization to take a shortcut when things don't match.
Note that if :(attr) is present, we can't return
all_entries_interesting / all_entries_not_interesting anymore because
we can't be certain about that. Not until match_pathspec_attrs() can
tell us "yes all these paths satisfy :(attr)".
Second note. Even though we walk a specific tree, we use attributes
from _worktree_ (or falling back to the index), not from .gitattributes
files on that tree. This by itself is not necessarily wrong, but the
user just have to be aware of this.

Make the split index write out its .git/sharedindex_* files with the
same permissions as .git/index. This only changes the behavior when
core.sharedRepository isn't set, i.e. the user's umask settings will
be respected.
This hasn't been the case ever since the split index was originally
implemented in c18b80a0e8 ("update-index: new options to
enable/disable split index mode", 2014-06-13). A mkstemp()-like
function has always been used to create it. First mkstemp() itself,
and then later our own mkstemp()-like in
f6ecc62dbf ("write_shared_index(): use tempfile module", 2015-08-10)
A related bug was fixed in df801f3f9f ("read-cache: use shared perms
when writing shared index", 2017-06-25). Since then the split index
has respected core.sharedRepository.
However, using that setting should not be required simply to make git
obey the user's umask setting. It's intended for the use-case of
overriding whatever that umask is set to. This fixes cases where the
user has e.g. set his umask to 022 on a shared server in anticipation
of other user's needing to run "status", "log" etc. in his repository.

The "git stash" command insists on having a usable user identity to
the same degree as the "git commit-tree" and "git commit" commands
do, because it uses the same codepath that creates commit objects
as these commands.
It is not strictly necesary to do so. Check if we will barf before
creating commit objects and then supply fake identity to please the
machinery that creates commits.
Add test to document that stash executes correctly both with and
without valid ident.
This is not that much of usability improvement, as the users who run
"git stash" would eventually want to record their changes that are
temporarily stored in the stashes in a more permanent history by
committing, and they must do "git config user.{name,email}" at that
point anyway, so arguably this change is only delaying a step that
is necessary to work in the repository.

Knowing the original names (hashes) of commits can sometimes enable
post-filtering that would otherwise be difficult or impossible. In
particular, the desire to rewrite commit messages which refer to other
prior commits (on top of whatever other filtering is being done) is
very difficult without knowing the original names of each commit.
In addition, knowing the original names (hashes) of blobs can allow
filtering by blob-id without requiring re-hashing the content of the
blob, and is thus useful as a small optimization.
Once we add original ids for both commits and blobs, we may as well
add them for tags too for completeness. Perhaps someone will have a
use for them.
This commit teaches a new --show-original-ids option to fast-export
which will make it add a 'original-oid <hash>' line to blob, commits,
and tags. It also teaches fast-import to parse (and ignore) such
lines.

git filter-branch has a nifty feature allowing you to rewrite, e.g. just
the last 8 commits of a linear history
git filter-branch $OPTIONS HEAD~8..HEAD
If you try the same with git fast-export, you instead get a history of
only 8 commits, with HEAD~7 being rewritten into a root commit. There
are two alternatives:
1) Don't use the negative revision specification, and when you're
filtering the output to make modifications to the last 8 commits,
just be careful to not modify any earlier commits somehow.
2) First run 'git fast-export --export-marks=somefile HEAD~8', then
run 'git fast-export --import-marks=somefile HEAD~8..HEAD'.
Both are more error prone than I'd like (the first for obvious reasons;
with the second option I have sometimes accidentally included too many
revisions in the first command and then found that the corresponding
extra revisions were not exported by the second command and thus were
not modified as I expected). Also, both are poor from a performance
perspective.
Add a new --reference-excluded-parents option which will cause
fast-export to refer to commits outside the specified rev-list-args
range by their sha1sum. Such a stream will only be useful in a
repository which already contains the necessary commits (much like the
restriction imposed when using --no-data).
Note from Peff:
I think we might be able to do a little more optimization here. If
we're exporting HEAD^..HEAD and there's an object in HEAD^ which is
unchanged in HEAD, I think we'd still print it (because it would not
be marked SHOWN), but we could omit it (by walking the tree of the
boundary commits and marking them shown). I don't think it's a
blocker for what you're doing here, but just a possible future
optimization.

If file paths are specified to fast-export and a ref points to a commit
that does not touch any of the relevant paths, then that ref would
sometimes fail to be exported. (This depends on whether any ancestors
of the commit which do touch the relevant paths would be exported with
that same ref name or a different ref name.) To avoid this problem,
put *all* specified refs into extra_refs to start, and then as we export
each commit, remove the refname used in the 'commit $REFNAME' directive
from extra_refs. Then, in handle_tags_and_duplicates() we know which
refs actually do need a manual reset directive in order to be included.
This means that we do need some special handling for excluded refs; e.g.
if someone runs
git fast-export ^master master
then they've asked for master to be exported, but they have also asked
for the commit which master points to and all of its history to be
excluded. That logically means ref deletion. Previously, such refs
were just silently omitted from being exported despite having been
explicitly requested for export.

If file paths are specified to fast-export and multiple refs point to a
commit that does not touch any of the relevant file paths, then
fast-export can hit problems. fast-export has a list of additional refs
that it needs to explicitly set after exporting all blobs and commits,
and when it tries to get_object_mark() on the relevant commit, it can
get a mark of 0, i.e. "not found", because the commit in question did
not touch the relevant paths and thus was not exported. Trying to
import a stream with a mark corresponding to an unexported object will
cause fast-import to crash.
Avoid this problem by taking the commit the ref points to and finding an
ancestor of it that was exported, and make the ref point to that commit
instead.

If --tag-of-filtered-object=rewrite is specified along with a set of
paths to limit what is exported, then any tags pointing to old commits
that do not contain any of those specified paths cause problems. Since
the old tagged commit is not exported, fast-export attempts to rewrite
such tags to an ancestor commit which was exported. If no such commit
exists, then fast-export currently die()s. Five years after the tag
rewriting logic was added to fast-export (see commit 2d8ad46919,
"fast-export: Add a --tag-of-filtered-object option for newly dangling
tags", 2009-06-25), fast-import gained the ability to delete refs (see
commit 4ee1b225b9, "fast-import: add support to delete refs",
2014-04-20), so now we do have a valid option to rewrite the tag to.
Delete these tags instead of dying.

When writing a bundle to a file, the bundle code actually creates
"your.bundle.lock" using our lockfile interface. We feed that output
descriptor to a child git-pack-objects via run-command, which has the
quirk that it closes the output descriptor in the parent.
To avoid confusing the lockfile code (which still thinks the descriptor
is valid), we dup() it, and operate on the duplicate.
However, this has a confusing side effect: after the dup() but before we
call pack-objects, we have _two_ descriptors open to the lockfile. If we
call die() during that time, the lockfile code will try to clean up the
partially-written file. It knows to close() the file before unlinking,
since on some platforms (i.e., Windows) the open file would block the
deletion. But it doesn't know about the duplicate descriptor. On
Windows, triggering an error at the right part of the code will result
in the cleanup failing and the lockfile being left in the filesystem.
We can solve this by moving the dup() much closer to start_command(),
shrinking the window in which we have the second descriptor open. It's
easy to place this in such a way that no die() is possible. We could
still die due to a signal in the exact wrong moment, but we already
tolerate races there (e.g., a signal could come before we manage to put
the file on the cleanup list in the first place).
As a bonus, this shields create_bundle() itself from the duplicate-fd
trick, and we can simplify its error handling (note that the lock
rollback now happens unconditionally, but that's OK; it's a noop if we
didn't open the lock in the first place).
The included test uses an empty bundle to cause a failure at the right
spot in the code, because that's easy to trigger (the other likely
errors are write() problems like ENOSPC). Note that it would already
pass on non-Windows systems (because they are happy to unlink an
already-open file).

On Windows, when we refer to `/an/absolute/path/to/git`, it magically
resolves `git.exe` at that location. Except if something of the name
`git` exists next to that `git.exe`. So if we call `$BUILD_DIR/git`, it
will find `$BUILD_DIR/git.exe` *only* if there is not, say, a directory
called `$BUILD_DIR/git`.
Such a directory, however, exists in Git for Windows when building with
Visual Studio (our Visual Studio project generator defaults to putting
the build files into a directory whose name is the base name of the
corresponding `.exe`).
In the bin-wrappers/* scripts, we already take pains to use `git.exe`
rather than `git`, as this could pick up the wrong thing on Windows
(i.e. if there exists a `git` file or directory in the build directory).
Now we do the same in the tests' start-up code.
This also helps when testing an installed Git, as there might be even
more likely some stray file or directory in the way.
Note: the only way we can record whether the `.exe` suffix is by writing
it to the `GIT-BUILD-OPTIONS` file and sourcing it at the beginning of
`t/test-lib.sh`. This is not a requirement introduced by this patch, but
we move the call to be able to use the `$X` variable that holds the file
extension, if any.
Note also: the many, many calls to `git this` and `git that` are
unaffected, as the regular PATH search will find the `.exe` files on
Windows (and not be confused by a directory of the name `git` that is
in one of the directories listed in the `PATH` variable), while
`/path/to/git` would not, per se, know that it is looking for an
executable and happily prefer such a directory.

The command 'git ls-remote --sort=authordate <remote>' segfaults when
run outside of a repository, ever since the introduction of its
'--sort' option in 1fb20dfd8e (ls-remote: create '--sort' option,
2018-04-09).
While in general the 'git ls-remote' command can be run outside of a
repository just fine, its '--sort=<key>' option with certain keys does
require access to the referenced objects. This sorting is implemented
using the generic ref-filter sorting facility, which already handles
missing objects gracefully with the appropriate 'missing object
deadbeef for HEAD' message. However, being generic means that it
checks replace refs while trying to retrieve an object, and while
doing so it accesses the 'git_replace_ref_base' variable, which has
not been initialized and is still a NULL pointer when outside of a
repository, thus causing the segfault.
Make ref-filter more careful upfront while parsing the format string,
and make it error out when encountering a format atom requiring object
access when we are not in a repository. Also add a test to ensure
that 'git ls-remote --sort' fails gracefully when executed outside of
a repository.

The initial fetch during a clone doesn't transfer refs matching
additional fetch refspecs given on the command line as configuration
variables, e.g. '-c remote.origin.fetch=<refspec>'. This contradicts
the documentation stating that configuration variables specified via
'git clone -c <key>=<value> ...' "take effect immediately after the
repository is initialized, but before the remote history is fetched"
and the given example specifically mentions "adding additional fetch
refspecs to the origin remote". Furthermore, one-shot configuration
variables specified via 'git -c <key>=<value> clone ...', though not
written to the newly created repository's config file, live during the
lifetime of the 'clone' command, including the initial fetch. All
this implies that any fetch refspecs specified this way should already
be taken into account during the initial fetch.
The reason for this is that the initial fetch is not a fully fledged
'git fetch' but a bunch of direct calls into the fetch/transport
machinery with clone's own refs-to-refspec matching logic, which
bypasses parts of 'git fetch' processing configured fetch refspecs.
This logic only considers a single default refspec, potentially
influenced by options like '--single-branch' and '--mirror'. The
configured refspecs are, however, already read and parsed properly
when clone calls remote.c:remote_get(), but it never looks at the
parsed refspecs in the resulting 'struct remote'.
Modify clone to take the remote's configured fetch refspecs into
account to retrieve all matching refs during the initial fetch. Note
that we have to explicitly add the default fetch refspec to the
remote's refspecs, because at that point the remote only includes the
fetch refspecs specified on the command line.
Add tests to check that refspecs given both via 'git clone -c ...' and
'git -c ... clone' retrieve all refs matching either the default or
the additional refspecs, and that it works even when the user
specifies an alternative remote name via '--origin=<name>'.

SHA-1 is weak and we need to transition to a new hash function. For
some time, we have referred to this new function as NewHash. Recently,
we decided to pick SHA-256 as NewHash. The reasons behind the choice of
SHA-256 are outlined in the thread starting at [1] and in the commit
history for the hash function transition document.
Add a basic implementation of SHA-256 based off libtomcrypt, which is in
the public domain. Optimize it and restructure it to meet our coding
standards. Pull in the update and final functions from the SHA-1 block
implementation, as we know these function correctly with all compilers.
This implementation is slower than SHA-1, but more performant
implementations will be introduced in future commits.
Wire up SHA-256 in the list of hash algorithms, and add a test that the
algorithm works correctly.
Note that with this patch, it is still not possible to switch to using
SHA-256 in Git. Additional patches are needed to prepare the code to
handle a larger hash algorithm and further test fixes are needed.

Before 73a834e9e2 ("range-diff: relieve callers of low-level

conditions to turn

expect "git checkout frotz" to create the branch "frotz" and there

file content is not helping. This is reported in Git mailing list [2]
and even used as an example of "Git is bad" elsewhere [3].
We normally try to do the right thing, but when there are multiple
"right things" to do, it's best to leave it to the user to decide.
Check this case, ask the user to to disambiguate:
- "git checkout -- foo" will check out path "foo"
- "git checkout foo --" will dwim and create branch "foo" [4]
For users who do not want dwim, use --no-guess. It's useless in this
particular case because "git checkout --no-guess foo --" will just
fail. But it could be used by scripts.

A fourth class of configuration files (in addition to the
traditional "system wide", "per user in the $HOME directory" and

Commit 43662b23ab (format-patch: keep cover-letter diffstat wrapped in
72 columns - 2018-01-24) uncondtionally sets stat width to 72 when
generating diffstat for the cover letter, ignoring --stat from command
line. But it should only do so when stat width is still default
(i.e. stat_width == 0).
In order to fix this, we should only set stat_width if stat_width is
zero. But it will never be. Commit 071dd0ba43 (format-patch: reduce
patch diffstat width to 72 - 2018-02-01) makes sure that default stat
width will be 72 (ignoring $COLUMNS, but could still be overriden by
--stat). So all we need to do here is drop the assignment.

`--exclude` from rev-list and rev-parse fails to exclude references if
the next `--branches`, `--tags` or `--remotes` use the optional
inclusive glob because those options are implemented as particular cases
of `--glob=`, which itself requires that exclude patterns begin with
'refs/'.
But it makes sense for `--branches=glob` and friends to be aware that
exclusions patterns for them shouldn't be 'refs/<type>/' prefixed, the
same way exclude patterns for `--branches` and friends (without the
optional glob) already are.
Let's record in 'refs.c:struct ref_filter' which context the exclude
pattern is tied to, so refs.c:filter_refs() can decide if it should
ignore the prefix when trying to match.

The documentation of `--exclude=` option from rev-list and rev-parse
explicitly states that exclude patterns *should not* start with 'refs/'
when used with `--branches`, `--tags` or `--remotes`.
However, following this advice results in refereces not being excluded
if the next `--branches`, `--tags`, `--remotes` use the optional
inclusive glob.
Demonstrate this failure.

When editing patches e.g. in `git add -e`, it is quite common that a
hunk ends up having no -/+ lines, i.e. it is now supposed to do nothing.
This use case was broken by ad6e8ed37b (apply: reject a hunk that does
not do anything, 2015-06-01) with the good intention of catching a very
real, different issue in hand-edited patches.
So let's use the `--recount` option as the tell-tale whether the user
would actually be okay with no-op hunks.
Add a test case to make sure that this use case does not regress again.

When we detect that a `merge` can be skipped because the merged commit
is already an ancestor of HEAD, we do not need to commit, therefore
writing the MERGE_HEAD file is useless.
It is actually worse than useless: a subsequent `git commit` will pick
it up and think that we want to merge that commit, still.
To avoid that, move the code that writes the MERGE_HEAD file to a
location where we already know that the `merge` cannot be skipped.

When calling `merge` on a branch that has already been merged, that
`merge` is skipped quietly, but currently a MERGE_HEAD file is being
left behind and will then be grabbed by the next `pick` (that did
not want to create a *merge* commit).
Demonstrate this.

p3400 makes a copy of the current repository to test git-rebase
performance, and creates new branches in the copy with `git checkout
-b'. If the original repository has branches with the same name as the
script is trying to create, this operation will fail.
This replaces these calls by `git checkout -B' to force the creation and
update of these branches.

Introduce optname() that does the early half of original opterror() to
come up with the name of the option reported back to the user, and use
it to kill opterror(). The callers of opterror() now directly call
error() using the string returned by opterror() instead.
There are a few issues with opterror()
- it tries to assemble an English sentence from pieces. This is not
great for translators because we give them pieces instead of a full
sentence.
- It's a wrapper around error() and needs some hack to let the
compiler know it always returns -1.
- Since it takes a string instead of printf format, one call site has
to assemble the string manually before passing to it.
Using error() directly solves the second and third problems.
It kind helps the first problem as well because "%s does foo" does
give a translator a full sentence in a sense and let them reorder if
needed. But it has limitations, if the subject part has to change
based on the rest of the sentence, that language is screwed. This is
also why I try to avoid calling optname() when 'flags' is known in
advance.
Mark of these strings for translation as well while at there.

In 73a834e9e2 ("range-diff: relieve callers of low-level configuration
burden", 2018-07-22) we broke passing down options like --no-patch,
--stat etc.
Fix that regression, and add a test asserting the pre-73a834e9e2
behavior for some of these diff options.
As noted in a change leading up to this ("range-diff doc: add a
section about output stability", 2018-11-07) the output is not meant
to be stable. So this regression test will likely need to be tweaked
once we get a "proper" --stat option.
See
https://public-inbox.org/git/nycvar.QRO.7.76.6.1811071202480.39@tvgsbejvaqbjf.bet/
for a further explanation of the regression. The fix here is not the
same as in Johannes's on-list patch, for reasons that'll be explained
in a follow-up commit.
The quoting of "EOF" here mirrors that of an earlier test. Perhaps
that should be fixed, but let's leave that up to a later cleanup
change.
