If our call to refs_read_raw_ref() fails, we check errno to
see if the ref is simply missing, or if we encountered a
more serious error. If it's just missing, then in "write"
mode (i.e., when RESOLVE_REFS_READING is not set), this is
perfectly fine.
However, checking for ENOENT isn't sufficient to catch all
missing-ref cases. In the filesystem backend, we may also
see EISDIR when we try to resolve "a" and "a/b" exists.
Likewise, we may see ENOTDIR if we try to resolve "a/b" and
"a" exists. In both of those cases, we know that our
resolved ref doesn't exist, but we return an error (rather
than reporting the refname and returning a null sha1).
This has been broken for a long time, but nobody really
noticed because the next step after resolving without the
READING flag is usually to lock the ref and write it. But in
both of those cases, the write will fail with the same
errno due to the directory/file conflict.
There are two cases where we can notice this, though:
1. If we try to write "a" and there's a leftover directory
already at "a", even though there is no ref "a/b". The
actual write is smart enough to move the empty "a" out
of the way.
This is reasonably rare, if only because the writing
code has to do an independent resolution before trying
its write (because the actual update_ref() code handles
this case fine). The notes-merge code does this, and
before the fix in the prior commit t3308 erroneously
expected this case to fail.
2. When resolving symbolic refs, we typically do not use
the READING flag because we want to resolve even
symrefs that point to unborn refs. Even if those unborn
refs could not actually be written because of d/f
conflicts with existing refs.
You can see this by asking "git symbolic-ref" to report
the target of a symref pointing past a d/f conflict.
We can fix the problem by recognizing the other "missing"
errnos and treating them like ENOENT. This should be safe to
do even for callers who are then going to actually write the
ref, because the actual writing process will fail if the d/f
conflict is a real one (and t1404 checks these cases).
Arguably this should be the responsibility of the
files-backend to normalize all "missing ref" errors into
ENOENT (since something like EISDIR may not be meaningful at
all to a database backend). However other callers of
refs_read_raw_ref() may actually care about the distinction;
putting this into resolve_ref() is the minimal fix for now.
The new tests in t1401 use git-symbolic-ref, which is the
most direct way to check the resolution by itself.
Interestingly we actually had a test that setup this case
already, but we only used it to verify that the funny state
could be overwritten, not that it could be resolved.
We also add a new test in t3200, as "branch -m" was the
original motivation for looking into this. What happens is
this:
0. HEAD is pointing to branch "a"
1. The user asks to rename "a" to "a/b".
2. We create "a/b" and delete "a".
3. We then try to update any worktree HEADs that point to
the renamed ref (including the main repo HEAD). To do
that, we have to resolve each HEAD. But now our HEAD is
pointing at "a", and we get EISDIR due to the loose
"a/b". As a result, we think there is no HEAD, and we
do not update it. It now points to the bogus "a".
Interestingly this case used to work, but only accidentally.
Before 31824d180d (branch: fix branch renaming not updating
HEADs correctly, 2017-08-24), we'd update any HEAD which we
couldn't resolve. That was wrong, but it papered over the
fact that we were incorrectly failing to resolve HEAD.
So while the bug demonstrated by the git-symbolic-ref is
quite old, the regression to "branch -m" is recent.

A test in t3308 wants to make sure that we don't
accidentally merge into "refs/notes/dir" when it exists as a
directory, so it does:
mkdir .git/refs/notes/dir
git -c core.notesRef=refs/notes/dir merge ...
and expects the second command to fail. But that
understimates the refs code, which is smart enough to remove
useless directories in the refs hierarchy. The test
succeeded only because of a bug which prevented resolving
refs/notes/dir for writing, even though an actual ref update
would succeed.
In preparation for fixing that bug, let's switch to creating
a real ref in refs/notes/dir, which is a more realistic
situation.

lookup_blob() and lookup_tree() can return NULL if they find an object
of an unexpected type. Accessing the object member is undefined in that
case. Cast the result to a struct object pointer instead; we can do
that because object is the first member of all object types. This trick
is already used in other places in the code.
An error message is already shown by object_as_type(), which is called
by the lookup functions. The walk callback functions are expected to
handle NULL object pointers passed to them, but put_object_name() needs
a valid object, so avoid calling it without one.

Peff points out that different atom parsers handle the empty
"sub-argument" list differently. An example of this is the format
"%(refname:)".
Since callers often use `string_list_split` (which splits the empty
string with any delimiter as a 1-ary string_list containing the empty
string), this makes handling empty sub-argument strings non-ergonomic.
Let's fix this by declaring that atom parser implementations must
not care about distinguishing between the empty string "%(refname:)"
and no sub-arguments "%(refname)". Current code aborts, either with
"unrecognised arg" (e.g. "refname:") or "does not take args"
(e.g. "body:") as an error message.

It can be handy to use `--color=always` (or it's synonym
`--color`) on the command-line to convince a command to
produce color even if it's stdout isn't going to the
terminal or a pager.
What's less clear is whether it makes sense to set config
variables like color.ui to `always`. For a one-shot like:
git -c color.ui=always ...
it's potentially useful (especially if the command doesn't
directly support the `--color` option). But setting `always`
in your on-disk config is much muddier, as you may be
surprised when piped commands generate colors (and send them
to whatever is consuming the pipe downstream).
Some people have done this anyway, because:
1. The documentation for color.ui makes it sound like
using `always` is a good idea, when you almost
certainly want `auto`.
2. Traditionally not every command (and especially not
plumbing) respected color.ui in the first place. So
the confusion came up less frequently than it might
have.
The situation changed in 136c8c8b8f (color: check color.ui
in git_default_config(), 2017-07-13), which negated point
(2): now scripts using only plumbing commands (like
add-interactive) are broken by this setting.
That commit was fixing real issues (e.g., by making
`color.ui=never` work, since `auto` is the default), so we
don't want to just revert it. We could turn `always` into a
noop in plumbing commands, but that creates a hard-to-explain
inconsistency between the plumbing and other commands.
Instead, let's just turn `always` into `auto` for all config.
This does break the "one-shot" config shown above, but again,
we're probably better to have simple and consistent rules than
to try to special-case command-line config.
There is one place where `always` should retain its meaning:
on the command line, `--color=always` should continue to be
the same as `--color`, overriding any isatty checks. Since the
command-line parser also depends on git_config_colorbool(), we
can use the existence of the "var" string to deterine whether
we are serving the command-line or the config.

When ref-filter learned about want_color() in 11b087adfd
(ref-filter: consult want_color() before emitting colors,
2017-07-13), it became useful to be able to turn colors off
and on for specific commands. For git-branch, you can do so
with --color/--no-color.
But for git-for-each-ref and git-tag, the other users of
ref-filter, you have no option except to tweak the
"color.ui" config setting. Let's give both of these commands
the usual color command-line options.
This is a bit more obvious as a method for overriding the
config. And it also prepares us for the behavior of "always"
changing (so that we are still left with a way of forcing
color when our output goes to a non-terminal).

The point of the test-terminal script is to simulate in the
test scripts an environment where output is going to a real
terminal.
But since test-lib.sh also sets TERM=dumb, the simulation
isn't very realistic. The color code will skip auto-coloring
for TERM=dumb, leading to us liberally sprinkling
test_terminal env TERM=vt100 git ...
through the test suite to convince the tests to actually
generate colors. Let's set TERM for programs run under
test_terminal, which is one less thing for test-writers to
remember.
In most cases the callers can be simplified, but note there
is one interesting case in t4202. It uses test_terminal to
check the auto-enabling of --decorate, but the expected
output _doesn't_ contain colors (because TERM=dumb
suppresses them). Using TERM=vt100 is closer to what the
real world looks like; adjust the expected output to match.

The %(contents) atom takes a contents "field" as its argument. Since
"trailers" is one of those fields, extend contents_atom_parser to parse
"trailers"'s arguments when used through "%(contents)", like:
%(contents:trailers:unfold,only)
A caveat: trailers_atom_parser expects NULL when no arguments are given
(see: `parse_ref_filter_atom`). This is because string_list_split (given
a maxsplit of -1) returns a 1-ary string_list* containing the given
string if the delimiter could not be found using `strchr`.
To simulate this behavior without teaching trailers_atom_parser to

The checkpoint command cycles packfiles if object_count != 0, a sensible
test or there would be no pack files to write. Since 820b931012, the
command also dumps branches, tags and marks, but still conditionally.
However, it is possible for a command stream to modify refs or create
marks without creating any new objects.
For example, reset a branch (and keep fast-import running):
$ git fast-import
reset refs/heads/master
from refs/heads/master^
checkpoint
but refs/heads/master remains unchanged.
Other example: a commit command that re-creates an object that already
exists in the object database.
The man page also states that checkpoint "updates the refs" and that
"placing a progress command immediately after a checkpoint will inform
the reader when the checkpoint has been completed and it can safely
access the refs that fast-import updated". This wasn't always true
without this patch.
This fix unconditionally calls dump_{branches,tags,marks}() for all
checkpoint commands. dump_branches() and dump_tags() are cheap to call
in the case of a no-op.
Add tests to t9300 that observe the (non-packfiles) effects of

It is possible that we are missing the submodule either completely or
partially, which we currently differentiate with different error messages
depending on whether (1) the whole submodule object store is missing or
(2) just the needed for this particular diff. (1) is reported as
"not initialized", and (2) is reported as "commits not present".
If a submodule is deinit'ed its repository data is still around inside
the superproject, such that the diff can still be produced. In that way
the error message (1) is misleading as we can have a diff despite the
submodule being not initialized.
Downgrade the error message (1) to be the same as (2) and just say
the commits are not present, as that is the true reason why the diff
cannot be shown.

Some tools like IDEs or fancy editors may periodically run
commands like "git status" in the background to keep track
of the state of the repository. Some of these commands may
refresh the index and write out the result in an
opportunistic way: if they can get the index lock, then they
update the on-disk index with any updates they find. And if
not, then their in-core refresh is lost and just has to be
recomputed by the next caller.
But taking the index lock may conflict with other operations
in the repository. Especially ones that the user is doing
themselves, which _aren't_ opportunistic. In other words,
"git status" knows how to back off when somebody else is
holding the lock, but other commands don't know that status
would be happy to drop the lock if somebody else wanted it.
There are a couple possible solutions:
1. Have some kind of "pseudo-lock" that allows other
commands to tell status that they want the lock.
This is likely to be complicated and error-prone to
implement (and maybe even impossible with just
dotlocks to work from, as it requires some
inter-process communication).
2. Avoid background runs of commands like "git status"
that want to do opportunistic updates, preferring
instead plumbing like diff-files, etc.
This is awkward for a couple of reasons. One is that
"status --porcelain" reports a lot more about the
repository state than is available from individual
plumbing commands. And two is that we actually _do_
want to see the refreshed index. We just don't want to
take a lock or write out the result. Whereas commands
like diff-files expect us to refresh the index
separately and write it to disk so that they can depend
on the result. But that write is exactly what we're
trying to avoid.
3. Ask "status" not to lock or write the index.
This is easy to implement. The big downside is that any
work done in refreshing the index for such a call is
lost when the process exits. So a background process
may end up re-hashing a changed file multiple times
until the user runs a command that does an index
refresh themselves.
This patch implements the option 3. The idea (and the test)
is largely stolen from a Git for Windows patch by Johannes
Schindelin, 67e5ce7f63 (status: offer *not* to lock the
index and update it, 2016-08-12). The twist here is that
instead of making this an option to "git status", it becomes
a "git" option and matching environment variable.
The reason there is two-fold:
1. An environment variable is carried through to
sub-processes. And whether an invocation is a
background process or not should apply to the whole
process tree. So you could do "git --no-optional-locks
foo", and if "foo" is a script or alias that calls
"status", you'll still get the effect.
2. There may be other programs that want the same
treatment.
I've punted here on finding more callers to convert,
since "status" is the obvious one to call as a repeated
background job. But "git diff"'s opportunistic refresh
of the index may be a good candidate.
The test is taken from 67e5ce7f63, and it's worth repeating
Johannes's explanation:
Note that the regression test added in this commit does
not *really* verify that no index.lock file was written;
that test is not possible in a portable way. Instead, we
verify that .git/index is rewritten *only* when `git
status` is run without `--no-optional-locks`.

submodule.<name>.update can be assigned an arbitrary command via setting
it to "!command". When this command is found in the regular config, Git
ought to just run that command instead of other update mechanisms.
However if that command is just found in the .gitmodules file, it is
potentially untrusted, which is why we do not run it. Add a test

When creating a new branch B by copying the branch A that happens to
be the current branch, it also updates HEAD to point at the new
branch. It probably was made this way because "git branch -c A B"
piggybacked its implementation on "git branch -m A B",
This does not match the usual expectation. If I were sitting on a
blue chair, and somebody comes and repaints it to red, I would
accept ending up sitting on a chair that is now red (I am also OK to
stand, instead, as there no longer is my favourite blue chair). But
if somebody creates a new red chair, modelling it after the blue
chair I am sitting on, I do not expect to be booted off of the blue
chair and ending up on sitting on the new red one.
Let's fix this before it hits 'next'. Those who want to create a
new branch and switch to it can do "git checkout B" after doing a
"git branch -c B", and if that operation is so useful and deserves a
short-hand way to do so, perhaps extend "git checkout -b B" to copy
configurations while creating the new branch B.

The handle_command() function matches an incoming command
string with a sequence of starts_with() checks. But it also
surrounds these with a switch on the first character of the
command, which lets us jump to the right block of
starts_with() without going linearly through the list.
However, each case arm of the switch falls through to the
one below it. This is pointless (we know that a command
starting with 'b' does not need to check any of the commands
in the 'c' block), and it makes gcc's -Wimplicit-fallthrough
complain.
We could solve this by adding a break at the end of each
block. However, this optimization isn't helping anything.
Even if it does make matching faster (which is debatable),
this is code that is run only in the test suite, and each
run receives at most two of these "commands". We should
favor simplicity and readability over micro-optimizing.
Instead, let's drop the switch statement completely and
replace it with an if/else cascade.

Commit dc944b65f1 (get_sha1_with_context: dynamically
allocate oc->path, 2017-05-19) changed the rules that
callers must follow for seeing if we parsed a path in the
object name. The rules switched from "check if the oc.path
buffer is empty" to "check if the oc.path pointer is NULL".
But that commit forgot to update some sites in
cat_one_file(), meaning we might dereference a NULL pointer.
You can see this by making a path-aware request like
--textconv without specifying --path, and giving an object
name that doesn't have a path in it. Like:
git cat-file --textconv HEAD
which will reliably segfault.

When run with the "-C" option, fast-export writes 'C' commands in its
output whenever the internal diff mechanism detects a file copy,
indicating that fast-import should copy the given existing file to the
given new filename. However, the diff mechanism works against the
prior version of the file, whereas fast-import uses whatever is current.
This causes issues when a commit both modifies a file and uses it as the
source for a copy.
Therefore, teach fast-export to refrain from writing 'C' when it has
already written a modification command for a file.
An existing test in t9350-fast-export is also fixed in this patch. The
existing line "C file6 file7" copies the wrong version of file6, but it
has coincidentally worked because file7 was subsequently overridden.

Currently, rev-parse only interprets a space ' ' character as the

character is placed between the option spec and the help text, it will
be interpreted as part of the long option name or as part of the arg
hint. If it is interpreted as part of the long option name, then
rev-parse will produce what will be interpreted as multiple arguments

Since commit 2d893df rev-parse will scan forward from the beginning of
the option string looking for a flag character. If there are no flag
characters then the scan will spill over into the help text and will
interpret the characters preceding the "flag" as part of the option-spec
i.e. the long option name.
For example, the following option spec:
exclame this does something!
will produce this 'set' expression when --exclame is specified:
set -- --exclame this does something --
which will be interpreted as four separate parameters by the shell. And
will produce a help string that looks like:
--exclame this does something
this does something!
git-rebase.sh has such an option (--autosquash), and so will add extra
parameters to the 'set' expression when --autosquash is used.
git-rebase continues to work correctly though because when it parses the
arguments, it ignores ones that it does not recognize.
Also, rev-parse --parseopt does not currently interpret a tab character
as a delimiter between the option spec and the help text. If a tab is
used at the end of the option spec, before the help text, and before a
space has been specified, then rev-parse will interpret the tab as part
of the preceding component (either the long name or the arg hint).
For example, the following option spec (note: there is a <tab> between
"frotz" and "enable"):
frotz enable frotzing
will produce this 'set' expression when --frotz is specified:
set -- --frotz enable --
which will be interpreted as 2 separate arguments by the shell.
git-rebase.sh has one of these too (--keep-empty). In this case the tab
is immediately followed by spaces so there are no additional parameters
produced on the command line. The only side-effect is misalignment in
the help text.

The return value of write_in_full() is either "-1", or the
requested number of bytes[1]. If we make a partial write
before seeing an error, we still return -1, not a partial
value. This goes back to f6aa66cb95 (write_in_full: really
write in full or return error on disk full., 2007-01-11).
So checking anything except "was the return value negative"
is pointless. And there are a couple of reasons not to do
so:
1. It can do a funny signed/unsigned comparison. If your
"len" is signed (e.g., a size_t) then the compiler will
promote the "-1" to its unsigned variant.
This works out for "!= len" (unless you really were
trying to write the maximum size_t bytes), but is a
bug if you check "< len" (an example of which was fixed
recently in config.c).
We should avoid promoting the mental model that you
need to check the length at all, so that new sites are
not tempted to copy us.
2. Checking for a negative value is shorter to type,
especially when the length is an expression.
3. Linus says so. In d34cf19b89 (Clean up write_in_full()
users, 2007-01-11), right after the write_in_full()
semantics were changed, he wrote:
I really wish every "write_in_full()" user would just
check against "<0" now, but this fixes the nasty and
stupid ones.
Appeals to authority aside, this makes it clear that
writing it this way does not have an intentional
benefit. It's a historical curiosity that we never
bothered to clean up (and which was undoubtedly
cargo-culted into new sites).
So let's convert these obviously-correct cases (this
includes write_str_in_full(), which is just a wrapper for
write_in_full()).
[1] A careful reader may notice there is one way that
write_in_full() can return a different value. If we ask
write() to write N bytes and get a return value that is
_larger_ than N, we could return a larger total. But
besides the fact that this would imply a totally broken
version of write(), it would already invoke undefined
behavior. Our internal remaining counter is an unsigned
size_t, which means that subtracting too many byte will
wrap it around to a very large number. So we'll instantly
begin reading off the end of the buffer, trying to write
gigabytes (or petabytes) of data.

While git doesn't track empty directories, git archive can be tricked
into putting some into archives. One way is to construct an empty tree
object, as t5004 does. While that is supported by the object database,
it can't be represented in the index and thus it's unlikely to occur in
the wild.
Another way is using the literal name of a directory in an exclude
pathspec -- its contents are are excluded, but the directory stub is
included. That's inconsistent: exclude pathspecs containing wildcards
don't leave empty directories in the archive.
Yet another way is have a few levels of nested subdirectories (e.g.
d1/d2/d3/file1) and ignoring the entries at the leaves (e.g. file1).
The directories with the ignored content are ignored as well (e.g. d3),
but their empty parents are included (e.g. d2).
As empty directories are not supported by git, they should also not be
written into archives. If an empty directory is really needed then it
can be tracked and archived by placing an empty .gitignore file in it.
There already is a mechanism in place for suppressing empty directories.
When read_tree_recursive() encounters a directory excluded by a pathspec
then it enters it anyway because it might contain included entries. It
calls the callback function before it is able to decide if the directory
is actually needed. For that reason git archive adds directories to a
queue and writes entries for them only when it encounters the first
child item -- but currently only if pathspecs with wildcards are used.
Queue *all* directories, no matter if there even are pathspecs present.
This prevents git archive from writing entries for empty directories in
all cases.

The check_has_commit helper uses resolves a submodule entry to a
commit, when validating its existence. As a side effect this means
tolerates a submodule entry pointing to a tag, which is not a valid
submodule entry that git commands would know how to cope with.
Tighten the check to require an actual commit, not a tag pointing to a
commit.
Also improve the error handling when a submodule entry points to
non-commit (e.g., a blob) to error out instead of warning and
pretending the pointed to object doesn't exist.

The git-cvsserver script is old and largely unmaintained
these days. But git-shell allows untrusted users to run it
out of the box, significantly increasing its attack surface.
Let's drop it from git-shell's list of internal handlers so
that it cannot be run by default. This is not backwards
compatible. But given the age and development activity on
CVS-related parts of Git, this is likely to impact very few
users, while helping many more (i.e., anybody who runs
git-shell and had no intention of supporting CVS).
There's no configuration mechanism in git-shell for us to
add a boolean and flip it to "off". But there is a mechanism
for adding custom commands, and adding CVS support here is
fairly trivial. Let's document it to give guidance to
anybody who really is still running cvsserver.

When processing a `files_ref_store` transaction, it is sometimes
necessary to delete some references from the "packed-refs" file. Do
that using a reference transaction conducted against the
`packed_ref_store`.
This change further decouples `files_ref_store` from
`packed_ref_store`. It also fixes multiple problems, including the two
revealed by test cases added in the previous commit.
First, the old code didn't obtain the `packed-refs` lock until
`files_transaction_finish()`. This means that a failure to acquire the
`packed-refs` lock (e.g., due to contention with another process)
wasn't detected until it was too late (problems like this are supposed
to be detected in the "prepare" phase). The new code acquires the
`packed-refs` lock in `files_transaction_prepare()`, the same stage of
the processing when the loose reference locks are being acquired,
removing another reason why the "prepare" phase might succeed and the
"finish" phase might nevertheless fail.
Second, the old code deleted the loose version of a reference before
deleting any packed version of the same reference. This left a moment
when another process might think that the packed version of the
reference is current, which is incorrect. (Even worse, the packed
version of the reference can be arbitrarily old, and might even point
at an object that has since been garbage-collected.)
Third, if a reference deletion fails to acquire the `packed-refs` lock
altogether, then the old code might leave the repository in the
incorrect state (possibly corrupt) described in the previous
paragraph.
Now we activate the new "packed-refs" file (sans any references that
are being deleted) *before* deleting the corresponding loose
references. But we hold the "packed-refs" lock until after the loose
references have been finalized, thus preventing a simultaneous
"pack-refs" process from packing the loose version of the reference in
the time gap, which would otherwise defeat our attempt to delete it.

Currently, a loose reference is deleted even before locking the
`packed-refs` file, let alone deleting any packed version of the
reference. This leads to two problems, demonstrated by two new tests:
* While a reference is being deleted, other processes might see the
old, packed value of the reference for a moment before the packed
version is deleted. Normally this would be hard to observe, but we
can prolong the window by locking the `packed-refs` file externally
before running `update-ref`, then unlocking it before `update-ref`'s
attempt to acquire the lock times out.
* If the `packed-refs` file is locked so long that `update-ref` fails
to lock it, then the reference can be left permanently in the
incorrect state described in the previous point.
In a moment, both problems will be fixed.

Similar to 65969d43d1 (merge: honor prepare-commit-msg hook, 2011-02-14)
merge should also honor the commit-msg hook: When a merge is stopped due
to conflicts or --no-commit, the subsequent commit calls the commit-msg
hook. However, it is not called after a clean merge. Fix this
inconsistency by invoking the hook after clean merges as well.
This change is motivated by Gerrit's commit-msg hook to install a ChangeId
trailer into the commit message. Without such a ChangeId, Gerrit refuses
to accept any commit by default, such that the inconsistency of (not)
running the commit-msg hook between commit and merge leads to confusion
and might block people from getting their work done.
As the githooks man page is very vocal about the possibility of skipping
the commit-msg hook via the --no-verify option, implement the option
in merge, too.
'git merge --continue' is currently implemented as calling cmd_commit
with no further arguments. This works for most other merge related options,
such as demonstrated via the --allow-unrelated-histories flag in the
test. The --no-verify option however is not remembered across invocations
of git-merge. Originally the author assumed an alternative in which the
'git merge --continue' command accepts the --no-verify flag, but that
opens up the discussion which flags are allows to the continued merge
command and which must be given in the first invocation.

This is to address concerns raised by ThreadSanitizer on the mailing list
about threaded unprotected R/W access to map.size with my previous "disallow

See:
https://public-inbox.org/git/adb37b70139fd1e2bac18bfd22c8b96683ae18eb.1502780344.git.martin.agren@gmail.com/
Add API to hashmap to disable item counting and thus automatic rehashing.
Also include API to later re-enable them.
When item counting is disabled, the map.size field is invalid. So to
prevent accidents, the field has been renamed and an accessor function
hashmap_get_size() has been added. All direct references to this
field have been been updated. And the name of the field changed
to map.private_size to communicate this.
Here is the relevant output from ThreadSanitizer showing the problem:

We already set ASAN_OPTIONS to abort if it finds any errors.
As we start to experiment with LSAN, the leak sanitizer,
it's convenient if we give it the same treatment.
Note that ASAN is actually a superset of LSAN and can do the
leak detection itself. So this only has an effect if you
specifically build with "make SANITIZE=leak" (leak detection
but not the rest of ASAN). Building with just LSAN results
in a build that runs much faster. That makes the
build-test-fix cycle more pleasant.
In the long run, once we've fixed or suppressed all the
leaks, it will probably be worth turning leak-detection on
for ASAN and just using that (to check both leaks _and_
memory errors in a single test run). But there's still a lot
of work before we get there.

The --verbose test option cannot be used with test harnesses
like "prove". Instead, you must use --verbose-log.
Since the --valgrind option implies --verbose, that means
that it cannot be used with prove. I.e., this does not work:
prove t0000-basic.sh :: --valgrind
You'd think it could be fixed by doing:
prove t0000-basic.sh :: --valgrind --verbose-log
but that doesn't work either, because the implied --verbose
takes precedence over --verbose-log. If the user has given

so the shared ref's reflog is scanned over and over again.
We could update refs API to pass "per-worktree only" flag to avoid
that. But long term we should be able to obtain a "per-worktree only"
ref store and would need to revert the changes in reflog iteration
API. So let's just wait until then.
add_reflogs_to_pending() is called by reachable.c so by default "git
prune" will examine reflog from all worktrees.

refs/bisect is unfortunately per-worktree, so we need to look in
per-worktree logs/refs/bisect in addition to per-repo logs/refs. The
current iterator only goes through per-repo logs/refs.
Use merge iterator to walk two ref stores at the same time and pick
per-worktree refs from the right iterator.
PS. Note the unsorted order of for_each_reflog in the test. This is
supposed to be OK, for now. If we enforce order on for_each_reflog()
then some more work will be required.

Unless single_worktree is set, --all now adds HEAD from all worktrees.
Since reachable.c code does not use setup_revisions(), we need to call
other_head_refs_submodule() explicitly there to have the same effect on
"git prune", so that we won't accidentally delete objects needed by some
other HEADs.
A new FIXME is added because we would need something like
int refs_other_head_refs(struct ref_store *, each_ref_fn, cb_data);
in addition to other_head_refs() to handle it, which might require
int get_submodule_worktrees(const char *submodule, int flags);
It could be a separate topic to reduce the scope of this one.

This is the result of single_worktree flag never being set (no way to up
until now). To get objects from current index only, set single_worktree.
The other add_index_objects_to_pending's caller is mark_reachable_objects()
(e.g. "git prune") which also mark objects from all indexes.

This is a followup over 9d33439 (send-email: only allow one address
per body tag, 2017-02-20). The first iteration did allow writting
Cc: <foo@example.com> # garbage
but did so by matching the regex ([^>]*>?), i.e. stop after the first
instance of '>'. However, it did not properly deal with
Cc: foo@example.com # garbage
Fix this using a new function strip_garbage_one_address, which does
essentially what the old ([^>]*>?) was doing, but dealing with more
corner-cases. Since we've allowed
Cc: "Foo # Bar" <foobar@example.com>
in previous versions, it makes sense to continue allowing it (but we
still remove any garbage after it). OTOH, when an address is given
without quoting, we just take the first word and ignore everything
after.

There are two bugs that sort of work together and cause
problems. Let's start with one in replace_each_worktree_head_symref.
Before fa099d2322 (worktree.c: kill parse_ref() in favor of
refs_resolve_ref_unsafe() - 2017-04-24), this code looks like this:
if (strcmp(oldref, worktrees[i]->head_ref))
continue;
set_worktree_head_symref(...);
After fa099d2322, it is possible that head_ref can be NULL. However,
the updated code takes the wrong exit. In the error case (NULL
head_ref), we should "continue;" to the next worktree. The updated
code makes us _skip_ "continue;" and update HEAD anyway.
The NULL head_ref is triggered by the second bug in add_head_info (in
the same commit). With the flag RESOLVE_REF_READING, resolve_ref_unsafe()
will abort if it cannot resolve the target ref. For orphan checkouts,
HEAD always points to an unborned branch, resolving target ref will
always fail. Now we have NULL head_ref. Now we always update HEAD.
Correct the logic in replace_ function so that we don't accidentally
update HEAD on error. As it turns out, correcting the logic bug above
breaks branch renaming completely, thanks to the second bug.
"git branch -[Mm]" does two steps (on a normal checkout, no orphan!):
- rename the branch on disk (e.g. refs/heads/abc to refs/heads/def)
- update HEAD if it points to the branch being renamed.
At the second step, since the branch pointed to by HEAD (e.g. "abc") no
longer exists on disk, we run into a temporary orphan checkout situation
that has been just corrected to _not_ update HEAD. But we need to update
HEAD since it's not actually an orphan checkout. We need to update HEAD
to move out of that orphan state.
Correct add_head_info(), remove RESOLVE_REF_READING flag. With the flag
gone, we should always return good "head_ref" in orphan checkouts (either
temporary or permanent). With good head_ref, things start to work again.

If the `git merge` process is killed while waiting for the editor to
finish, the merge state is lost but the prepared merge msg and tree is kept.
So, a subsequent `git commit` creates a squashed merge even when the
user asked for proper merge commit originally.
Demonstrate the problem with a test crafted after the in t7502. The test
requires EXECKEEPSPID (thus does not run under MINGW).
Save the merge state earlier (in the non-squash case) so that it does
not get lost. This makes the test pass.

These two configuration variables are described in the documentation
to take an expiry period expressed in the number of days:
gc.rerereResolved::
Records of conflicted merge you resolved earlier are
kept for this many days when 'git rerere gc' is run.
The default is 60 days.
gc.rerereUnresolved::
Records of conflicted merge you have not resolved are
kept for this many days when 'git rerere gc' is run.
The default is 15 days.
There is no strong reason not to allow a more general "approxidate"
expiry specification, e.g. "5.days.ago", or "never".
Rename the config_get_expiry() helper introduced in the previous
step to git_config_get_expiry_in_days() and move it to a more
generic place, config.c, and use date.c::parse_expiry_date() to do
so. Give it an ability to allow the caller to tell among three
cases (i.e. there is no "gc.rerereResolved" config, there is and it
is correctly parsed into the *expiry variable, and there was an
error in parsing the given value). The current caller can work
correctly without using the return value, though.
In the future, we may find other variables that only allow an
integer that specifies "this many days" or other unit of time, and
when it happens we may need to drop "_days" suffix from the name of
the function and instead pass the "scale" value as another parameter.
But this will do for now.

The test blindly trusted that there may be _some_ entries left in
the rerere database, and used them by updating their timestamps to
see if the gc threshold variables are honoured correctly. This
won't work if there is no entry in the database when the test
begins.
Instead, clear the rerere database, and populate it with a few known
entries (which are bogus, but for the purpose of testing "garbage
collection", it does not matter---we want to make sure we collect
old cruft, even if the files are corrupt rerere database entries),
and use them for the expiry test.

When a file had been commited with CRLF but now .gitattributes say
"* text=auto" (or core.autocrlf is true), the following does not
roundtrip, `git apply` fails:
printf "Added line\r\n" >>file &&
git diff >patch &&
git checkout -- . &&
git apply patch
Before applying the patch, the file from working tree is converted
into the index format (clean filter, CRLF conversion, ...). Here,
when commited with CRLF, the line endings should not be converted.
Note that `git apply --index` or `git apply --cache` doesn't call
convert_to_git() because the source material is already in index
format.
Analyze the patch if there is a) any context line with CRLF, or b)
if any line with CRLF is to be removed. In this case the patch file
`patch` has mixed line endings, for a) it looks like this:
diff --git a/one b/one
index 533790e..c30dea8 100644
--- a/one
+++ b/one
@@ -1 +1,2 @@
a\r
+b\r
And for b) it looks like this:
diff --git a/one b/one
index 533790e..485540d 100644
--- a/one
+++ b/one
@@ -1 +1 @@
-a\r
+b\r
If `git apply` detects that the patch itself has CRLF, (look at the
line " a\r" or "-a\r" above), the new flag crlf_in_old is set in
"struct patch" and two things will happen:
- read_old_data() will not convert CRLF into LF by calling
convert_to_git(..., SAFE_CRLF_KEEP_CRLF);
- The WS_CR_AT_EOL bit is set in the "white space rule",
CRLF are no longer treated as white space.
While at there, make it clear that read_old_data() in apply.c knows
what it wants convert_to_git() to do with respect to CRLF. In fact,
this codepath is about applying a patch to a file in the filesystem,
which may not exist in the index, or may exist but may not match
what is recorded in the index, or in the extreme case, we may not
even be in a Git repository. If convert_to_git() peeked at the
index while doing its work, it *would* be a bug.
Pass NULL instead of &the_index to convert_to_git() to make sure we
catch future bugs to clarify this.
Update the test in t4124: split one test case into 3:
- Detect the " a\r" line in the patch
- Detect the "-a\r" line in the patch
- Use LF in repo and CLRF in the worktree.

The existing behavior of diff --color-moved=zebra does not define the
minimum size of a block at all, instead relying on a heuristic applied
later to filter out sets of adjacent moved lines that are shorter than 3
lines long. This can be confusing, because a block could thus be colored
as moved at the source but not at the destination (or vice versa),
depending on its neighbors.
Instead, teach diff that the minimum size of a block is 20 alphanumeric
characters, the same heuristic used by "git blame". This allows diff to
still exclude uninteresting lines appearing on their own (such as those
solely consisting of one or a few closing braces), as was the intention
of the adjacent-moved-line heuristic.
This requires a change in some tests in that some of their lines are no
longer considered to be part of a block, because they are too short.

sum(1) is a command for calculating checksums of the contents of files.
It was part of early editions of Unix ("Research Unix", 1972/1973, [1]).
cksum(1) appeared in 4.4BSD (1993) as a replacement [2], and became part
of POSIX.1-2008 [3]. OpenBSD 5.6 (2014) removed sum(1).
We only use sum(1) in t1002 to check for changes in three files. On
MinGW we use md5sum(1) instead. We could switch to the standard command
cksum(1) for all platforms; MinGW comes with GNU coreutils now, which
provides sum(1), cksum(1) and md5sum(1). Use our standard method for
checking for file changes instead: test_cmp.
It's more convenient because it shows differences nicely, it's faster on
MinGW because we have a special implementation there based only on
shell-internal commands, it's simpler as it allows us to avoid stripping
out unnecessary entries from the checksum file using grep(1), and it's
more consistent with the rest of the test suite.
We already compare changed files with their expected new contents using
diff(1), so we don't need to check with "test_must_fail test_cmp" if
they differ from their original state. A later patch could convert the
direct diff(1) calls to test_cmp as well.
With all sum(1) calls gone, remove the MinGW-specific implementation
from test-lib.sh as well.

We currently have one test for %(trailers). In preparation
for more, let's refactor a few bits:
- move the commit creation to its own setup step so it can
be reused by multiple tests
- add a trailer with whitespace continuation (to confirm
that it is left untouched)
- fix the sample text which claims the placeholder is %bT.
This was switched long ago to %(trailers)
- replace one "cat" with an "echo" when generating the
expected output. This saves a process (and sets a better
pattern for future tests to follow).

The point of "--only-trailers" is to give a caller an output
that's easy for them to parse. Getting rid of the
non-trailer material helps, but we still may see more
complicated syntax like whitespace continuation. Let's add
an option to unfold any continuation, giving the output as a
single "key: value" line per trailer.
As a bonus, this could be used even without --only-trailers
to clean up unusual formatting in the incoming data.
