Long ago in 628522ec14 (sha1-lookup: more memory efficient
search in sorted list of SHA-1, 2007-12-29) we added
sha1_entry_pos(), a binary search that uses the uniform
distribution of sha1s to scale the selection of mid-points.
As this was a performance experiment, we tied it to the
GIT_USE_LOOKUP environment variable and never enabled it by
default.
This code was successful in reducing the number of steps in
each search. But the overhead of the scaling ends up making
it slower when the cache is warm. Here are best-of-five
timings for running rev-list on linux.git, which will have
to look up every object:
$ time git rev-list --objects --all >/dev/null
real 0m35.357s
user 0m35.016s
sys 0m0.340s
$ time GIT_USE_LOOKUP=1 git rev-list --objects --all >/dev/null
real 0m37.364s
user 0m37.045s
sys 0m0.316s
The USE_LOOKUP version might have more benefit on a cold
cache, as the time to fault in each page would dominate. But
that would be for a single lookup. In practice, most
operations tend to look up many objects, and the whole pack
.idx will end up warm.
It's possible that the code could be better optimized to
compete with a naive binary search for the warm-cache case,
and we could have the best of both worlds. But over the
years nobody has done so, and this is largely dead code that
is rarely run outside of the test suite. Let's drop it in
the name of simplicity.
This lets us remove sha1_entry_pos() entirely, as the .idx
lookup code was the only caller. Note that sha1-lookup.c
still contains sha1_pos(), which differs from
sha1_entry_pos() in two ways:
- it has a different interface; it uses a function pointer
to access sha1 entries rather than a size/offset pair
describing the table's memory layout
- it only scales the initial selection of "mi", rather
than each iteration of the search
We can't get rid of this function, as it's called from
several places. It may be that we could replace it with a
simple binary search, but that's out of scope for this patch
(and would need benchmarking).

Both of these act on a string `value` which they parse as a boolean. The
"parse"-variant was introduced as a replacement for the "config"-variant
which for historical reasons takes an unused argument `name`. That it
was intended as a replacement is not obvious from commit 9a549d43
("config.c: rename git_config_maybe_bool_text and export it as
git_parse_maybe_bool", 2015-08-19), but that is what the background on
the mailing list suggests [1].
However, these two functions do not parse `value` in exactly the same
way. In particular, git_config_maybe_bool accepts integers (0 for false,
non-0 for true). This means there are two slightly different definitions
of "maybe_bool" in the code-base, and that every time a call to
git_config_maybe_bool is changed to use git_parse_maybe_bool, it risks
breaking someone's workflow.
Move the implementation of "config" into "parse" and make the latter a
trivial wrapper.
This also fixes the only user of git_parse_maybe_bool, `git push
--signed=..`.

When running, e.g., `git -c alias.bar=foo bar`, we expand the alias and
execute `git-foo` as a dashed external. This is true even if git foo is
a builtin. That is on purpose, and is motivated in a comment which was
added in commit 441981bc ("git: simplify environment save/restore
logic", 2016-01-26).
Shortly before we launch a dashed external, and unless we have already
found out whether we should use a pager, we check `pager.foo`. This was
added in commit 92058e4d ("support pager.* for external commands",
2011-08-18). If the dashed external is a builtin, this does not match
that commit's intention and is arguably wrong, since it would be cleaner
if we let the "dashed external builtin" handle `pager.foo`.
This has not mattered in practice, but a recent patch taught `git-tag`
to ignore `pager.tag` under certain circumstances. But, when started
using an alias, it doesn't get the chance to do so, as outlined above.
That recent patch added a test to document this breakage.
Do not check `pager.foo` before launching a builtin as a dashed
external, i.e., if we recognize the name of the external as a builtin.

Using, e.g., `git -c pager.tag tag -a new-tag` results in errors such as
"Vim: Warning: Output is not to a terminal" and a garbled terminal.
Someone who makes use of both `git tag -a` and `git tag -l` will
probably not set `pager.tag`, so that `git tag -a` will actually work,
at the cost of not paging output of `git tag -l`.
Use the mechanisms introduced in two earlier patches to ignore
`pager.tag` in git.c and let the `git tag` builtin handle it on its own.
Only respect `pager.tag` when running in list-mode.
There is a window between where the pager is started before and after
this patch. This means that early errors can behave slightly different
before and after this patch. Since operation-parsing has to happen
inside this window, this can be seen with `git -c pager.tag="echo pager
is used" tag -l --unknown-option`. This change in paging-behavior should
be acceptable since it only affects erroneous usages.
Update the documentation and update tests.
If an alias is used to run `git tag -a`, then `pager.tag` will still be
respected. Document this known breakage. It will be fixed in a later
commit. Add a similar test for `-l`, which works.

Construct tests with a few different subcommands. First, use -l. Second,
use "no arguments" and --contains, since those imply -l. (There are
more arguments which imply -l, but using these two should be enough.)
Third, use -a as a representative for "not -l". Actually, the tests use
`git tag -am` so no editor is launched, but that is irrelevant, since we
just want to see whether the pager is used or not. Make one of the tests

command may handle it. It's likely to break, but it may also
do something dangerous and unwanted (technically it could
even do something useful, but that seems unlikely).
We should err on the side of caution and reject this before
we even run the command.
The hostname check matches the one we do in a similar
circumstance for ssh. The port check is not present for ssh,
but there it's not necessary because the syntax is "-p
<port>", and there's no ambiguity on the parsing side.
It's not clear whether you can actually get a negative port
to the proxy here or not. Doing:
git fetch git://remote:-1234/repo.git
keeps the "-1234" as part of the hostname, with the default
port of 9418. But it's a good idea to keep this check close

One of the tricks that `contrib/workdir/git-new-workdir` plays is to
making `packed-refs` in the new workdir a symlink to the `packed-refs`
file in the original repository. Before
42dfa7ecef ("commit_packed_refs(): use a staging file separate from
the lockfile", 2017-06-23), a lockfile was used as the staging file,
and because the `LOCK_NO_DEREF` was not used, the pointed-to file was
locked and modified.
But after that commit, the staging file was created using a tempfile,
with the end result that rewriting the `packed-refs` file in the
workdir overwrote the symlink rather than the original `packed-refs`
file.
Change `commit_packed_refs()` to use `get_locked_file_path()` to find
the path of the file that it should overwrite. Since that path was
properly resolved when the lockfile was created, this restores the
pre-42dfa7ecef behavior.
Also add a test case to document this use case and prevent a
regression like this from recurring.

The git UI can be improved by addressing the error messages to those

In particular, failure to apply a patch during a git rebase is a common

important to lead them toward the resolution of the conflict (which is a

When color placeholders like %(color:red) are used in a
ref-filter format, we unconditionally output the colors,
even if the user has asked us for no colors. This usually
isn't a problem when the user is constructing a --format on
the command line, but it means we may do the wrong thing
when the format is fed from a script or alias. For example:
$ git config alias.b 'branch --format=%(color:green)%(refname)'
$ git b --no-color
should probably omit the green color. Likewise, running:
$ git b >branches
should probably also omit the color, just as we would for
all baked-in coloring (and as we recently started to do for
user-specified colors in --pretty formats).
This commit makes both of those cases work by teaching
the ref-filter code to consult want_color() before
outputting any color. The color flag in ref_format defaults
to "-1", which means we'll consult color.ui, which in turn
defaults to the usual isatty() check on stdout. However,
callers like git-branch which support their own color config
(and command-line options) can override that.
The new tests independently cover all three of the callers
of ref-filter (for-each-ref, tag, and branch). Even though
these seem redundant, it confirms that we've correctly
plumbed through all of the necessary config to make colors
work by default.

The color placeholders have traditionally been
unconditional, showing colors even when git is not otherwise
configured to do so. This was not so bad for their original
use, which was on the command-line (and the user could
decide at that moment whether to add colors or not). But
these days we have configured formats via pretty.*, and
those should operate correctly in multiple contexts.
In 3082517 (log --format: teach %C(auto,black) to respect
color config, 2012-12-17), we gave an extended placeholder
that could be used to accomplish this. But it's rather
clunky to use, because you have to specify it individually
for each color (and their matching resets) in the format.
We shied away from just switching the default to auto,
because it is technically breaking backwards compatibility.
However, there's not really a use case for unconditional
colors. The most plausible reason you would want them is to
redirect "git log" output to a file. But there, the right
answer is --color=always, as it does the right thing both
with custom user-format colors and git-generated colors.
So let's switch to the more useful default. In the
off-chance that somebody really does find a use for
unconditional colors without wanting to enable the rest of
git's colors, we provide a new %C(always,...) to enable the
old behavior. And we can remind them of --color=always in
the documentation.

When rev-list pretty-prints a commit, it creates a new

presumably not many people use that with the rev-list
plumbing (as opposed to with git-log).
It will become more noticeable in a future patch, though,
when we start treating all user-format colors as auto-colors
(in which case it would become impossible to format colors
with rev-list, even with --color=always).

We normally try to avoid having two auto-gc operations run
at the same time, because it wastes resources. This was done
long ago in 64a99eb47 (gc: reject if another gc is running,
unless --force is given, 2013-08-08).
When we do a detached auto-gc, we run the ref-related
commands _before_ detaching, to avoid confusing lock
contention. This was done by 62aad1849 (gc --auto: do not
lock refs in the background, 2014-05-25).
These two features do not interact well. The pre-detach
operations are run before we check the gc.pid lock, meaning
that on a busy repository we may run many of them
concurrently. Ideally we'd take the lock before spawning any
operations, and hold it for the duration of the program.
This is tricky, though, with the way the pid-file interacts
with the daemonize() process. Other processes will check
that the pid recorded in the pid-file still exists. But
detaching causes us to fork and continue running under a
new pid. So if we take the lock before detaching, the
pid-file will have a bogus pid in it. We'd have to go back
and update it with the new pid after detaching. We'd also
have to play some tricks with the tempfile subsystem to
tweak the "owner" field, so that the parent process does not
clean it up on exit, but the child process does.
Instead, we can do something a bit simpler: take the lock
only for the duration of the pre-detach work, then detach,
then take it again for the post-detach work. Technically,
this means that the post-detach lock could lose to another
process doing pre-detach work. But in the long run this
works out.
That second process would then follow-up by doing
post-detach work. Unless it was in turn blocked by a third
process doing pre-detach work, and so on. This could in
theory go on indefinitely, as the pre-detach work does not
repack, and so need_to_gc() will continue to trigger. But
in each round we are racing between the pre- and post-detach
locks. Eventually, one of the post-detach locks will win the
race and complete the full gc. So in the worst case, we may
racily repeat the pre-detach work, but we would never do so
simultaneously (it would happen via a sequence of serialized
race-wins).

When doing a reflog walk, we use the commit's date to
do any date limiting. In earlier versions of Git, this could
lead to nonsense results, since a skipped commit would
truncate the traversal. So a sequence like:
git commit ...
git checkout week-old-branch
git checkout -
git log -g --since=1.day.ago
would stop at the week-old-branch, even though the "git
commit" entry further back is still interesting.
As of the prior commit, which uses a parent-less traversal
of the reflog, you get the whole reflog minus any commits
whose dates do not match the specified options. This is
arguably useful, as you could scan the reflogs for commits
that originated in a certain range.
But more likely a user doing a reflog walk wants to limit
based on the reflog entries themselves. You can simulate
--until with:
git log -g @{1.day.ago}
but there's no way to ask Git to traverse only back to a
certain date. E.g.:
# show me reflog entries from the past day
git log -g --since=1.day.ago
This patch teaches the revision machinery to prefer the
reflog entry dates to the commit dates when doing a reflog
walk. Technically this is a change in behavior that affects
plumbing, but the previous behavior was so buggy that it's
unlikely anyone was relying on it.

The reflog-walk system works by putting a ref's tip into the
pending queue, and then "traversing" the reflog by
pretending that the parent of each commit is the previous
reflog entry.
This causes a number of user-visible oddities, as documented
in t1414 (and the commit message which introduced it). We
can fix all of them in one go by replacing the fake-reflog
system with a much simpler one: just keeping a list of
reflogs to show, and walking through them entry by entry.
The implementation is fairly straight-forward, but there are
a few items to note:
1. We obviously must skip calling add_parents_to_list()
when we are traversing reflogs, since we do not want to
walk the original parents at all. As a result, we must call
try_to_simplify_commit() ourselves.
There are other parts of add_parents_to_list() we skip,
as well, but none of them should matter for a reflog
traversal:
- We do not allow UNINTERESTING commits, nor
symmetric ranges (and we bail when these are used
with "-g").
- Using --source makes no sense, since we aren't
traversing. The reflog selector shows the same
information with more detail.
- Using --first-parent is still sensible, since you
may want to see the first-parent diff for each
entry. But since we're not traversing, we don't
need to cull the parent list here.
2. Since we now just walk the reflog entries themselves,
rather than starting with the ref tip, we now look at
the "new" field of each entry rather than the "old"
(i.e., we are showing entries, not faking parents).
This removes all of the tricky logic around skipping
past root commits.
But note that we have no way to show an entry with the
null sha1 in its "new" field (because such a commit
obviously does not exist). Normally this would not
happen, since we delete reflogs along with refs, but
there is one special case. When we rename the currently
checked out branch, we write two reflog entries into
the HEAD log: one where the commit goes away, and
another where it comes back.
Prior to this commit, we show both entries with
identical reflog messages. After this commit, we show
only the "comes back" entry. See the update in t3200
which demonstrates this.
Arguably either is fine, as the whole double-entry
thing is a bit hacky in the first place. And until a
recent fix, we truncated the traversal in such a case
anyway, which was _definitely_ wrong.
3. We show individual reflogs in order, but choose which
reflog to show at each stage based on which has the
most recent timestamp. This interleaves the output
from multiple reflogs based on date order, which is
probably what you'd want with limiting like "-n 30".
Note that the implementation aims for simplicity. It
does a linear walk over the reflog queue for each
commit it pulls, which may perform badly if you
interleave an enormous number of reflogs. That seems
like an unlikely use case; if we did want to handle it,
we could probably keep a priority queue of reflogs,
ordered by the timestamp of their current tip entry.

When git-rev-list sees no pending commits, it shows a usage
message. This works even when reflog-walking is requested,
because the reflog-walk code currently puts the reflog tips
into the pending queue.
In preparation for refactoring the reflog-walk code, let's
explicitly check whether we have any reflogs to walk. For
now this is a noop, but the existing reflog tests will make
sure that it kicks in after the refactoring. Likewise, we'll
add a test that "rev-list -g" without specifying any reflogs
continues to fail (so that we know our check does not kick
in too aggressively).
Note that the implementation needs to go into its own
sub-function, as the walk code does not expose its innards
outside of reflog-walk.c.

Since 949af0684 (branch: use ref-filter printing APIs,
2017-01-10), git-branch's output is generated by passing a
custom format to the ref-filter code. This format forgot to
pass BRANCH_COLOR_LOCAL, meaning that local branches
(besides the current one) were never colored at all.
We can add it in the %(if) block where we decide whether the
branch is "current" or merely "local". Note that this means
the current/local coloring is either/or. You can't set:
[color "branch"]
local = blue
current = bold
and expect the current branch to be "bold blue". This
matches the pre-949af0684 behavior.

Since its inception, the general strategy of the reflog-walk
code has been to start with the tip commit for the ref, and
as we traverse replace each commit's parent pointers with
fake parents pointing to the previous reflog entry.
This lets us traverse the reflog as if it were a real
history, but it has some user-visible oddities. Namely:
1. The fake parents are used for commit selection and
display. So for example, "--merges" or "--no-merges"
are not useful, because the history appears as a linear
string of commits. Likewise, pathspec limiting is based
on the diff between adjacent entries, not the changes
actually introduced by a commit.
These are often the same (e.g., because the entry was
just running "git commit" and the adjacent entry _is_
the true parent), but it may not be in several common
cases. For instance, using "git reset" to jump around
history, or "git checkout" to move HEAD.
2. We reverse-map each commit back to its reflog. So when
it comes time to show commit X, we say "a-ha, we added
X because it was at the tip of the 'foo' reflog, so
let's show the foo reflog". But this leads to nonsense
results when you ask to traverse multiple reflogs: if
two reflogs have the same tip commit, we only map back
to one of them. Instead, we should show both.
3. If the tip of the reflog and the ref tip disagree on
the current value, we show the ref tip but give no
indication of the value in the reflog. This situation
isn't supposed to happen (since any ref update should
touch the reflog). But if it does, given that the
requested operation is to show the reflog, it makes
sense to prefer that.
This commit adds a new script with several expect_failure
tests to demonstrate the problems. This could be part of
the existing t1411, but it's a bit easier to start from a
fresh state, where we know exactly what will be in the log.
Since the new multiple-reflog tests are checking the actual
output, we can drop the "make sure we don't segfault" tests
from t1411, which are a strict subset of what we're doing
here.

reflog-walk: include all fields when freeing complete_reflogs
reflog-walk: don't free reflogs added to cache
reflog-walk: duplicate strings in complete_reflogs list
reflog-walk: skip over double-null oid due to HEAD rename
The add_reflog_for_walk() function keeps a cache mapping
refnames to their reflog contents. We use a cached reflog
entry if available, and otherwise allocate and store a new
one.
Since 5026b47175 (add_reflog_for_walk: avoid memory leak,
2017-05-04), when we hit an error parsing a date-based
reflog spec, we free the reflog memory but leave the cache
entry pointing to the now-freed memory.
We can fix this by just leaving the memory intact once it
has made it into the cache. This may leave an unused entry
in the cache, but that's OK. And it means we also catch a
similar situation: we may not have allocated at all in this
invocation, but simply be pointing to a cached entry from a
previous invocation (which is relying on that entry being
present).
The new test in t1411 exercises this case and fails when run
with --valgrind or ASan.

As part of the add_reflog_to_walk() function, we keep a
string_list mapping refnames to their reflog contents. This
serves as a cache so that accessing the same reflog twice
requires only a single copy of the log in memory.
The string_list is initialized via xcalloc, meaning its
strdup_strings field is set to 0. But after inserting a
string into the list, we unconditionally call free() on the
string, leaving the list pointing to freed memory. If
another reflog is added (e.g., "git log -g HEAD HEAD"), then
the second one may have unpredictable results.
The extra free was added by 5026b47175 (add_reflog_for_walk:
avoid memory leak, 2017-05-04). Though if you look
carefully, you can see that the code was buggy even before
then. If we tried to read the reflogs by time but came up
with no entries, we exited with an error, freeing the string
in that code path. So the bug was harder to trigger, but
still there.
We can fix it by just asking the string list to make a copy
of the string. Technically we could fix the problem by not
calling free() on our string (and just handing over
ownership to the string list), but there are enough
conditionals that it's quite hard to figure out which code
paths need the free and which do not. Simpler is better
here.
The new test reliably shows the problem when run with
--valgrind or ASAN.

Since 39ee4c6c2f (branch: record creation of renamed branch
in HEAD's log, 2017-02-20), a rename on the currently
checked out branch will create two entries in the HEAD
reflog: one where the branch goes away (switching to the
null oid), and one where it comes back (switching away from
the null oid).
This confuses the reflog-walk code. When walking backwards,
it first sees the null oid in the "old" field of the second
entry. Thanks to the "root commit" logic added by 71abeb753f
(reflog: continue walking the reflog past root commits,
2016-06-03), we keep looking for the next entry by scanning
the "new" field from the previous entry. But that field is
also null! We need to go just a tiny bit further, and look
at its "old" field. But with the current code, we decide the
reflog has nothing else to show and just give up. To the
user this looks like the reflog was truncated by the rename
operation, when in fact those entries are still there.
This patch does the absolute minimal fix, which is to look
back that one extra level and keep traversing.
The resulting behavior may not be the _best_ thing to do in
the long run (for example, we show both reflog entries each
with the same commit id), but it's a simple way to fix the
problem without risking further regressions.

It seems to be a little-known feature of `grep` (and it certainly came
as a surprise to this here developer who believed to know the Unix tools
pretty well) that multiple patterns can be passed in the same
command-line argument simply by separating them by newlines. Watch, and
learn:
$ printf '1\n2\n3\n' | grep "$(printf '1\n3\n')"
1
3
That behavior also extends to patterns passed via `-e`, and it is not
modified by passing the option `-E` (but trying this with -P issues the
error "grep: the -P option only supports a single pattern").
It seems that there are more old Unix hands who are surprised by this
behavior, as grep invocations of the form
grep "$(git rev-parse A B) C" file
were introduced in a85b377d04 (push: the beginning of "git push
--signed", 2014-09-12), and later faithfully copy-edited in b9459019bb
(push: heed user.signingkey for signed pushes, 2014-10-22).
Please note that the output of `git rev-parse A B` separates the object
IDs via *newlines*, not via spaces, and those newlines are preserved
because the interpolation is enclosed in double quotes.
As a consequence, these tests try to validate that the file contains
either A's object ID, or B's object ID followed by C, or both. Clearly,
however, what the test wanted to see is that there is a line that
contains all of them.
This is clearly unintended, and the grep invocations in question really
match too many lines.
Fix the test by avoiding the newlines in the patterns.

When a patch consists mostly of moving blocks of code around, it can
be quite tedious to ensure that the blocks are moved verbatim, and not
undesirably modified in the move. To that end, color blocks that are
moved within the same patch differently. For example (OM, del, add,
and NM are different colors):
[OM] -void sensitive_stuff(void)
[OM] -{
[OM] - if (!is_authorized_user())
[OM] - die("unauthorized");
[OM] - sensitive_stuff(spanning,
[OM] - multiple,
[OM] - lines);
[OM] -}
void another_function()
{
[del] - printf("foo");
[add] + printf("bar");
}
[NM] +void sensitive_stuff(void)
[NM] +{
[NM] + if (!is_authorized_user())
[NM] + die("unauthorized");
[NM] + sensitive_stuff(spanning,
[NM] + multiple,
[NM] + lines);
[NM] +}
However adjacent blocks may be problematic. For example, in this
potentially malicious patch, the swapping of blocks can be spotted:
[OM] -void sensitive_stuff(void)
[OM] -{
[OMA] - if (!is_authorized_user())
[OMA] - die("unauthorized");
[OM] - sensitive_stuff(spanning,
[OM] - multiple,
[OM] - lines);
[OMA] -}
void another_function()
{
[del] - printf("foo");
[add] + printf("bar");
}
[NM] +void sensitive_stuff(void)
[NM] +{
[NMA] + sensitive_stuff(spanning,
[NMA] + multiple,
[NMA] + lines);
[NM] + if (!is_authorized_user())
[NM] + die("unauthorized");
[NMA] +}
If the moved code is larger, it is easier to hide some permutation in the
code, which is why some alternative coloring is needed.
This patch implements the first mode:
* basic alternating 'Zebra' mode
This conveys all information needed to the user. Defer customization to
later patches.
First I implemented an alternative design, which would try to fingerprint
a line by its neighbors to detect if we are in a block or at the boundary.
This idea iss error prone as it inspected each line and its neighboring
lines to determine if the line was (a) moved and (b) if was deep inside
a hunk by having matching neighboring lines. This is unreliable as the
we can construct hunks which have equal neighbors that just exceed the
number of lines inspected. (Think of 'AXYZBXYZCXYZD..' with each letter
as a line, that is permutated to AXYZCXYZBXYZD..').
Instead this provides a dynamic programming greedy algorithm that finds
the largest moved hunk and then has several modes on highlighting bounds.
A note on the options '--submodule=diff' and '--color-words/--word-diff':
In the conversion to use emit_line in the prior patches both submodules
as well as word diff output carefully chose to call emit_line with sign=0.
All output with sign=0 is ignored for move detection purposes in this
patch, such that no weird looking output will be generated for these
cases. This leads to another thought: We could pass on '--color-moved' to
submodules such that they color up moved lines for themselves. If we'd do
so only line moves within a repository boundary are marked up.
It is useful to have moved lines colored, but there are annoying corner
cases, such as a single line moved, that is very common. For example
in a typical patch of C code, we have closing braces that end statement
blocks or functions.
While it is technically true that these lines are moved as they show up
elsewhere, it is harmful for the review as the reviewers attention is
drawn to such a minor side annoyance.
For now let's have a simple solution of hardcoding the number of
moved lines to be at least 3 before coloring them. Note, that the
length is applied across all blocks to find the 'lonely' blocks
that pollute new code, but do not interfere with a permutated
block where each permutation has less lines than 3.

Some `clean` / `smudge` filters may require a significant amount of
time to process a single blob (e.g. the Git LFS smudge filter might
perform network requests). During this process the Git checkout
operation is blocked and Git needs to wait until the filter is done to
continue with the checkout.
Teach the filter process protocol, introduced in edcc8581 ("convert: add
filter.<driver>.process option", 2016-10-16), to accept the status
"delayed" as response to a filter request. Upon this response Git
continues with the checkout operation. After the checkout operation Git
calls "finish_delayed_checkout" which queries the filter for remaining
blobs. If the filter is still working on the completion, then the filter
is expected to block. If the filter has completed all remaining blobs
then an empty response is expected.
Git has a multiple code paths that checkout a blob. Support delayed
checkouts only in `clone` (in unpack-trees.c) and `checkout` operations
for now. The optimization is most effective in these code paths as all
files of the tree are processed.

When using the hashmap a common need is to have access to caller provided
data in the compare function. A couple of times we abuse the keydata field
to pass in the data needed. This happens for example in patch-ids.c.
This patch changes the function signature of the compare function
to have one more void pointer available. The pointer given for each
invocation of the compare function must be defined in the init function
of the hashmap and is just passed through.
Documentation of this new feature is deferred to a later patch.
This is a rather mechanical conversion, just adding the new pass-through
parameter. However while at it improve the naming of the fields of all
compare functions used by hashmaps by ensuring unused parameters are
prefixed with 'unused_' and naming the parameters what they are (instead
of 'unused' make it 'unused_keydata').

Teach pull to optionally update submodules when '--recurse-submodules'
is provided. This will teach pull to run 'submodule update --rebase'
when the '--recurse-submodules' and '--rebase' flags are given under
specific circumstances.
On a rebase workflow:
=====================
1. Both sides change the submodule
------------------------------
Let's assume the following history in a submodule:
H---I---J---K---L local branch
\
M---N---O---P remote branch
and the following in the superproject (recorded submodule in parens):
A(H)---B(I)---F(K)---G(L) local branch
\
C(N)---D(N)---E(P) remote branch
In an ideal world this would rebase the submodule and rewrite
the submodule pointers that the superproject points at such that
the superproject looks like
A(H)---B(I) F(K')---G(L') rebased branch
\ /
C(N)---D(N)---E(P) remote branch
and the submodule as:
J---K---L (old dangeling tip)
/
H---I J'---K'---L' rebased branch
\ /
M---N---O---P remote branch
And if a conflict arises in the submodule the superproject rebase
would stop at that commit at which the submodule conflict occurs.
Currently a "pull --rebase" in the superproject produces
a merge conflict as the submodule pointer changes are
conflicting and cannot be resolved.
2. Local submodule changes only
-----------------------
Assuming histories as above, except that the remote branch
would not contain submodule changes, then a result as
A(H)---B(I) F(K)---G(L) rebased branch
\ /
C(I)---D(I)---E(I) remote branch
is desire-able. This is what currently happens in rebase.
If the recursive flag is given, the ideal git would
produce a superproject as:
A(H)---B(I) F(K')---G(L') rebased branch (incl. sub rebase!)
\ /
C(I)---D(I)---E(I) remote branch
and the submodule as:
J---K---L (old dangeling tip)
/
H---I J'---K'---L' locally rebased branch
\ /
M---N---O---P advanced branch
This patch doesn't address this issue, however
a test is added that this fails up front.
3. Remote submodule changes only
----------------------
Assuming histories as in (1) except that the local superproject branch
would not have touched the submodule the rebase already works out in the
superproject with no conflicts:
A(H)---B(I) F(P)---G(P) rebased branch (no sub changes)
\ /
C(N)---D(N)---E(P) remote branch
The recurse flag as presented in this patch would additionally
update the submodule as:
H---I J'---K'---L' rebased branch
\ /
M---N---O---P remote branch
As neither J, K, L nor J', K', L' are referred to from the superproject,
no rewriting of the superproject commits is required.
Conclusion for 'pull --rebase --recursive'
-----------------------------------------
If there are no local superproject changes it is sufficient to call
"submodule update --rebase" as this produces the desired results. In case
of conflicts, the behavior is the same as in 'submodule update --recursive'
which is assumed to be sane.
This patch implements (3) only.
On a merge workflow:
====================
We'll start off with the same underlying DAG as in (1) in the rebase
workflow. So in an ideal world a 'pull --merge --recursive' would
produce this:
H---I---J---K---L----X
\ /
M---N---O---P
with X as the new merge-commit in the submodule and the superproject
as:
A(H)---B(I)---F(K)---G(L)---Y(X)
\ /
C(N)---D(N)---E(P)
However modifying the submodules on the fly is not supported in git-merge
such that Y(X) is not easy to produce in a single patch. In fact git-merge
doesn't know about submodules at all.
However when at least one side does not contain commits touching the
submodule at all, then we do not need to perform the merge for the
submodule but a fast-forward can be done via checking out either L or P
in the submodule. This strategy is implemented in 68d03e4a6e (Implement
automatic fast-forward merge for submodules, 2010-07-07) already, so
to align with the rebase behavior we need to also update the worktree
of the submodule.

The existing message, "Initial commit", makes sense for the commit template
notifying users that it's their initial commit, but is confusing when
merely checking the status of a fresh repository (or orphan branch)
without having any commits yet.
Change the output of "status" to say "No commits yet" when "git
status" is run on a fresh repo (or orphan branch), while retaining the
current "Initial commit" message displayed in the template that's
displayed in the editor when the initial commit is being authored.
Correspondingly change the output of "short status" to "No commits yet
on " when "git status -sb" is run on a fresh repo (or orphan branch).
A few alternatives considered were,
* Waiting for initial commit
* Your current branch does not have any commits
* Current branch waiting for initial commit
The most succint one among the alternatives was chosen.

when the user asks to edit a hunk manually, we respect
core.commentChar in generating the edit instructions.
However, when we then strip out comment lines, we use a
simple regex like:
/^$commentChar/
If your chosen comment character is a regex metacharacter,
then that will behave in a confusing manner ("$", for
instance, would only eliminate blank lines, not actual
comment lines).
We can fix that by telling perl not to respect
metacharacters.

we make sure early ones are all interpretable as revs (and do not

pathspec with "magic" (e.g. ":/p/a/t/h" that matches p/a/t/h from
the top-level of the working tree, no matter what subdirectory you
are working from) are conservatively judged as "not a path", which

`for_each_bisect_ref()` is called by `for_each_bad_bisect_ref()` with
a term "bad". This used to make it call `for_each_ref_in_submodule()`
with a prefix "refs/bisect/bad". But the latter is the name of the
reference that is being sought, so the empty string was being passed
to the callback as the trimmed refname. Moreover, this questionable
practice was turned into an error by
b9c8e7f2fb prefix_ref_iterator: don't trim too much, 2017-05-22
It makes more sense (and agrees better with the documentation of
`--bisect`) for the callers to receive the full reference names. So
* Add a new function, `for_each_fullref_in_submodule()`, to the refs
API. This plugs a gap in the existing functionality, analogous to
`for_each_fullref_in()` but accepting a `submodule` argument.
* Change `for_each_bad_bisect_ref()` to call the new function rather

Add the ability to --copy a branch and its reflog and configuration,
this uses the same underlying machinery as the --move (-m) option
except the reflog and configuration is copied instead of being moved.
This is useful for e.g. copying a topic branch to a new version,
e.g. work to work-2 after submitting the work topic to the list, while
preserving all the tracking info and other configuration that goes
with the branch, and unlike --move keeping the other already-submitted
branch around for reference.
Like --move, when the source branch is the currently checked out
branch the HEAD is moved to the destination branch. In the case of
--move we don't really have a choice (other than remaining on a
detached HEAD) and in order to keep the functionality consistent, we
are doing it in similar way for --copy too.
The most common usage of this feature is expected to be moving to a
new topic branch which is a copy of the current one, in that case
moving to the target branch is what the user wants, and doesn't
unexpectedly behave differently than --move would.
One outstanding caveat of this implementation is that:
git checkout maint &&
git checkout master &&
git branch -c topic &&
git checkout -
Will check out 'maint' instead of 'master'. This is because the @{-N}
feature (or its -1 shorthand "-") relies on HEAD reflogs created by
the checkout command, so in this case we'll checkout maint instead of
master, as the user might expect. What to do about that is left to a
future change.

When we convert seconds-since-epochs timestamps into a
broken-down "struct tm", we do so by adjusting the timestamp
according to the known offset and then using gmtime() to
break down the result. This means that the resulting struct
"knows" that it's in GMT, even though the time it represents
is adjusted for a different zone. The fields where it stores
this data are not portably accessible, so we have no way to
override them to tell them the real zone info.
For the most part, this works. Our date-formatting routines
don't pay attention to these inaccessible fields, and use
the same tz info we provided for adjustment. The one
exception is when we call strftime(), whose %Z format
reveals this hidden timezone data.
We solved that by always showing the empty string for %Z.
This is allowed by POSIX, but not very helpful to the user.
We can't make this work in the general case, as there's no
portable function for setting an arbitrary timezone (and
anyway, we don't have the zone name for the author zones,
only their offsets).
But for the special case of the "-local" formats, we can
just skip the adjustment and use localtime() instead of
gmtime(). This makes --date=format-local:%Z work correctly,
showing the local timezone instead of an empty string.
The new test checks the result for "UTC", our default
test-lib value for $TZ. Using something like EST5 might be
more interesting, but the actual zone string is
system-dependent (for instance, on my system it expands to
just EST). Hopefully "UTC" is vanilla enough that every
system treats it the same.

We already test that "%z" and "%Z" show the right thing, but
we don't actually check that the time we display is the
correct one. Let's add two new tests:
1. Test that "format:" shows the time in the author's
timezone, just like the other time formats.
2. Test that "format-local:" shows time in the local
timezone. We don't want to use our normal UTC for this,
because its offset is zero (so the result would be
"correct" even if the code forgot to apply the offset
or applied it in the wrong direction).
We'll use the EST5 zone, which is already used
elsewhere in the script (and so is assumed to be
available everywhere).

There is no portable way to pass timezone information to strftime. Add
parameters for timezone offset and name to strbuf_addftime and let it
handle the timezone-related format specifiers %z and %Z internally.
Callers can opt out for %Z by passing NULL as timezone name. %z is
always handled internally -- this helps on Windows, where strftime would
expand it to a timezone name (same as %Z), in violation of POSIX.
Modifiers are not handled, e.g. %Ez is still passed to strftime.
Use an empty string as timezone name in show_date (the only current
caller) for now because we only have the timezone offset in non-local
mode. POSIX allows %Z to resolve to an empty string in case of missing
information.

Instead of discovering the .git/ directory, reading the config and then
trying to painstakingly reset all the global state if we did not find a
matching alias, let's use the early config machinery instead.
It may look like unnecessary work to discover the .git/ directory in the
early config machinery and then call setup_git_directory_gently() in the
case of a shell alias, repeating the very same discovery *again*.
However, we have to do this as the early config machinery takes pains
*not* to touch any global state, while shell aliases expect a possibly
changed working directory and at least the GIT_PREFIX and GIT_DIR
variables to be set.
This change also fixes a known issue where Git tried to read the pager
config from an incorrect path in a subdirectory of a Git worktree if an
alias expanded to a shell command.

When expanding aliases, the git_dir is set during the alias expansion
(by virtue of running setup_git_directory_gently()).
This git_dir may be relative to the current working directory, and
indeed often is simply ".git/".
When the alias expands to a shell command, we restore the original
working directory, though, yet we do not reset git_dir.
As a consequence, subsequent read_early_config() runs will mistake the
git_dir to be populated properly and not find the correct config.

When get_value() parses a key/value pair, it is possible that the line
number is decreased (because the \n has been consumed already) before the
key/value pair is passed to the callback function, to allow for the
correct line to be attributed in case of an error.
However, when git_parse_source() asks get_value() to parse the key/value

It's an easy mistake to add a repository inside another
repository, like:
git clone $url
git add .
The resulting entry is a gitlink, but there's no matching
.gitmodules entry. Trying to use "submodule init" (or clone
with --recursive) doesn't do anything useful. Prior to
v2.13, such an entry caused git-submodule to barf entirely.
In v2.13, the entry is considered "inactive" and quietly
ignored. Either way, no clone of your repository can do
anything useful with the gitlink without the user manually
adding the submodule config.
In most cases, the user probably meant to either add a real
submodule, or they forgot to put the embedded repository in
their .gitignore file.
Let's issue a warning when we see this case. There are a few
things to note:
- the warning will go in the git-add porcelain; anybody
wanting to do low-level manipulation of the index is
welcome to create whatever funny states they want.
- we detect the case by looking for a newly added gitlink;
updates via "git add submodule" are perfectly reasonable,
and this avoids us having to investigate .gitmodules
entirely
- there's a command-line option to suppress the warning.
This is needed for git-submodule itself (which adds the
entry before adding any submodule config), but also
provides a mechanism for other scripts doing
submodule-like things.
We could make this a hard error instead of a warning.
However, we do add lots of sub-repos in our test suite. It's
not _wrong_ to do so. It just creates a state where users
may be surprised. Pointing them in the right direction with
a gentle hint is probably the best option.
There is a config knob that can disable the (long) hint. But
I intentionally omitted a config knob to disable the warning
entirely. Whether the warning is sensible or not is
generally about context, not about the user's preferences.
If there's a tool or workflow that adds gitlinks without
matching .gitmodules, it should probably be taught about the
new command-line option, rather than blanket-disabling the
warning.

The `git stash push` command recently gained the ability to get a
pathspec as its argument to only stash matching files. Calling this
command from a subdirectory does not work, though, as one of the first
things we do is changing to the top level directory without keeping
track of the prefix from which the command is being run.
Fix the shortcoming by storing the prefix previous to the call to
`cd_to_toplevel` and then subsequently using `git rev-parse --prefix` to
correctly resolve the pathspec. Add a test to catch future breakage of
this usecase.

Add a test for the case when only one parameter is passed to '-m'
(move/rename) option.
For example - if 'git branch -m bbb' is run while checked out on aaa
branch, it should rename the currently checked out branch to bbb.
There was no test for this particular case with only one parameter
for -m option. However, there's one similar test case for -M option.
Add test for making sure HEAD points to the bbb (new branch name). Also
add a test for making sure the reflog that is moved to 'bbb' retains
entries created for the currently checked out branch. Note that since
the topmost entry on reflog for bbb will be about branch creation, we
compare bbb@{1} (instead of bbb@{0}) with aaa@{0} to make sure the
reflog for bbb retains entries from aaa.

Commit a1283866b (t5313: test bounds-checks of
corrupted/malicious pack/idx files, 2016-02-25) added a test
that requires our corrupted pack index to have two objects.
The entry for the first one remains untouched, but we
corrupt the entry for second one. Since the index stores the
entries in sha1-sorted order, this means that the test must
make sure that the sha1 of the object we expect to be
corrupted ("$object") sorts after the other placeholder
object.
That commit used the HEAD commit as the placeholder, but the
script never calls test_tick. That means that the commit
object (and thus its sha1) depends on the timestamp when the
test script is run. This usually works in practice, because
the sha1 of $object starts with "fff". The commit object
will sort after that only 1 in 4096 times, but when it does
the test will fail.
One obvious solution is to add the test_tick call to get a
deterministic commit sha1. But since we're relying on the
sort order for the test to function, let's make that very
explicit by just generating a second blob with a known sha1.

Since commit 99caeed05 (Let 'git <command> -h' show usage
without a git dir, 2009-11-09), the git wrapper handles "-h"
specially, skipping any repository setup but still calling
the builtin's cmd_foo() function. This means that every
cmd_foo() must be ready to handle this case, but we don't
have any systematic tests. This led to "git am -h" being
broken for some time without anybody noticing.
This patch just tests that "git foo -h" works for every
builtin, where we see a 129 exit code (the normal code for
our usage() helper), and that the word "usage" appears in
the output.

Add support for v2 of the PCRE API. This is a new major version of
PCRE that came out in early 2015[1].
The regular expression syntax is the same, but while the API is
similar, pretty much every function is either renamed or takes
different arguments. Thus using it via entirely new functions makes
sense, as opposed to trying to e.g. have one compile_pcre_pattern()
that would call either PCRE v1 or v2 functions.
Git can now be compiled with either USE_LIBPCRE1=YesPlease or
USE_LIBPCRE2=YesPlease, with USE_LIBPCRE=YesPlease currently being a
synonym for the former. Providing both is a compile-time error.
With earlier patches to enable JIT for PCRE v1 the performance of the
release versions of both libraries is almost exactly the same, with
PCRE v2 being around 1% slower.
However after I reported this to the pcre-dev mailing list[2] I got a
lot of help with the API use from Zoltán Herczeg, he subsequently
optimized some of the JIT functionality in v2 of the library.
Running the p7820-grep-engines.sh performance test against the latest
Subversion trunk of both, with both them and git compiled as -O3, and
the test run against linux.git, gives the following results. Just the

I.e. the two are either neck-to-neck, but PCRE v2 usually pulls ahead,
when it does it's around 20% faster.
A brief note on thread safety: As noted in pcre2api(3) & pcre2jit(3)
the compiled pattern can be shared between threads, but not some of
the JIT context, however the grep threading support does all pattern &
JIT compilation in separate threads, so this code doesn't need to
concern itself with thread safety.
See commit 63e7e9d8b6 ("git-grep: Learn PCRE", 2011-05-09) for the
initial addition of PCRE v1. This change follows some of the same
patterns it did (and which were discussed on list at the time),
e.g. mocking up types with typedef instead of ifdef-ing them out when
USE_LIBPCRE2 isn't defined. This adds some trivial memory use to the
program, but makes the code look nicer.

When `git pull --rebase --autostash` in a dirty repository resulted in a
fast-forward, nothing was being autostashed and the pull failed. This
was due to a shortcut to avoid running rebase when we can fast-forward,
but autostash is ignored on that codepath.
Now we will only take the shortcut if autostash is not in effect.
Based on a few tests against the git.git repo, the shortcut does not
seem to give us significant performance benefits, on Linux at least.
Regardless, it is more important to be correct than to be fast.

In builtin/grep.c we parse the config before evaluating the command line
options. This makes the task of teaching grep to respect the new config
option 'submodule.recurse' very easy by just parsing that option.
As an alternative I had implemented a similar structure to treat
submodules as the fetch/push command have, including
* aligning the meaning of the 'recurse_submodules' to possible submodule
values RECURSE_SUBMODULES_* as defined in submodule.h.
* having a callback to parse the value and
* reacting to the RECURSE_SUBMODULES_DEFAULT state that was the initial
state.
However all this is not needed for a true boolean value, so let's keep
it simple. However this adds another place where "submodule.recurse" is
parsed.

In a later patch we want to introduce a config option to trigger the
submodule recursing by default. As this option should be available and
uniform across all commands that deal with submodules we'd want to test
for this option in the submodule update library.
So instead of calling the whole test set again for
"git -c submodule.recurse foo" instead of "git foo --recurse-submodules",
we'd only want to introduce one basic test that tests if the option is
recognized and respected to not overload the test suite.
Change the test functions by taking only the argument and assemble the
command inside the test function by embedding the arguments into the
command that is "git $arguments --recurse-submodules".
It would be nice to do this for all functions in lib-submodule-update,
but we cannot do that for the non-recursing tests, as there we do not
just pass in a git command but whole functions. (See t3426 for example)

When "git checkout", "git merge", etc. manipulates the in-core
index, various pieces of information in the index extensions are
discarded from the original state, as it is usually not the case
that they are kept up-to-date and in-sync with the operation on the
main index. The untracked cache extension is copied across these
operations now, which would speed up "git status" (as long as the
cache is properly invalidated).
* dt/unpack-save-untracked-cache-extension:
unpack-trees: preserve index extensions
A recent update to t5545-push-options.sh started skipping all the
tests in the script when a web server testing is disabled or
unavailable, not just the ones that require a web server. Non HTTP
tests have been salvaged to always run in this script.
* jc/skip-test-in-the-middle:
t5545: enhance test coverage when no http server is installed
test: allow skipping the remainder
The recently introduced "[includeIf "gitdir:$dir"] path=..."
mechansim has further been taught to take symlinks into account.
The directory "$dir" specified in "gitdir:$dir" may be a symlink to
a real location, not something that $(getcwd) may return. In such
a case, a realpath of "$dir" is compared with the real path of the
current repository to determine if the contents from the named path
should be included.
* ab/conditional-config-with-symlinks:
config: match both symlink & realpath versions in IncludeIf.gitdir:*
There is no good reason why "git fetch $there $sha1" should fail
when the $sha1 names an object at the tip of an advertised ref,
even when the other side hasn't enabled allowTipSHA1InWant.
* jt/fetch-allow-tip-sha1-implicitly:
fetch-pack: always allow fetching of literal SHA1s
