This could be misleading for those who alias a command with options

show the manual of "cherry-pick", and the reader would not be told
to pay close attention to the part that describes the "--no-commit"
option until closing the pager that showed the contents of the
manual, if the pager is configured to restore the original screen,
or would not be told at all, if the pager simply makes the message
on the standard error scroll away.

upload-pack: fix broken if/else chain in config callbackJeff King Wed, 24 Oct 2018 07:27:52 +0000 (03:27 -0400)

upload-pack: fix broken if/else chain in config callback

The upload_pack_config() callback uses an if/else chain
like:

if (!strcmp(var, "a"))
...
else if (!strcmp(var, "b"))
...
etc

This works as long as the conditions are mutually exclusive,
but one of them is not. 20b20a22f8 (upload-pack: provide a
hook for running pack-objects, 2016-05-18) added:

else if (current_config_scope() != CONFIG_SCOPE_REPO) {
... check some more options ...
}

That was fine in that commit, because it came at the end of
the chain. But later, 10ac85c785 (upload-pack: add object
filtering for partial clone, 2017-12-08) did this:

else if (current_config_scope() != CONFIG_SCOPE_REPO) {
... check some more options ...
} else if (!strcmp("uploadpack.allowfilter", var))
...

We'd always check the scope condition first, meaning we'd
_only_ respect allowfilter when it's in the repo config. You
can see this with:

git -c uploadpack.allowfilter=true upload-pack . | head -1

which will not advertise the filter capability (but will
after this patch). We never noticed because:

- our tests always set it in the repo config

- in protocol v2, we use a different code path that
actually calls repo_config_get_bool() separately, so
that _does_ work. Real-world people experimenting with
this may be using v2.

The more recent uploadpack.allowrefinwant option is in the
same boat.

There are a few possible fixes:

1. Bump the scope conditional back to the bottom of the
chain. But that just means somebody else is likely to
make the same mistake later.

2. Make the conditional more like the others. I.e.:

else if (!current_config_scope() != CONFIG_SCOPE_REPO &&
!strcmp(var, "uploadpack.notallowedinrepo"))

This works, but the idea of the original structure was
that we may grow multiple sensitive options like this.

3. Pull it out of the chain entirely. The chain mostly
serves to avoid extra strcmp() calls after we've found
a match. But it's not worth caring about those. In the
worst case, when there isn't a match, we're already
hitting every strcmp (and this happens regularly for
stuff like "core.bare", etc).

This patch does (3).

range-diff: allow to diff files regardless of submodule... Lucas De Marchi Wed, 24 Oct 2018 19:46:17 +0000 (12:46 -0700)

range-diff: allow to diff files regardless of submodule config

If we have `submodule.diff = log' in the configuration file
or `--submodule=log' is given as argument, range-diff fails
to compare both diffs and we only get the following output:

Submodule a 0000000...0000000 (new submodule)

Even if the repository doesn't have any submodule.

That's because the mode in diff_filespec is not correct and when
flushing the diff, down in builtin_diff() we will enter the condition:

if (o->submodule_format == DIFF_SUBMODULE_LOG &&
(!one->mode || S_ISGITLINK(one->mode)) &&
(!two->mode || S_ISGITLINK(two->mode))) {
show_submodule_summary(o, one->path ? one->path : two->path,
&one->oid, &two->oid,

t5410: use longer path for sample script

t5410 creates a sample script "alternate-refs", and sets
core.alternateRefsCommand to just "alternate-refs". That
shouldn't work, as "." is not in our $PATH, and so we should
not find it.

However, due to a bug in run-command.c, we sometimes find it
anyway! Even more confusing, this bug is only in the
fork-based version of run-command. So the test passes on
Linux (etc), but fails on Windows.

In preparation for fixing the run-command bug, let's use a
more complete path here.

run-command: mark path lookup errors with ENOENTJeff King Wed, 24 Oct 2018 07:38:00 +0000 (03:38 -0400)

run-command: mark path lookup errors with ENOENT

Since commit e3a434468f (run-command: use the
async-signal-safe execv instead of execvp, 2017-04-19),
prepare_cmd() does its own PATH lookup for any commands we
run (on non-Windows platforms).

However, its logic does not match the old execvp call when
we fail to find a matching entry in the PATH. Instead of
feeding the name directly to execv, execvp would consider
that an ENOENT error. By continuing and passing the name
directly to execv, we effectively behave as if "." was
included at the end of the PATH. This can have confusing and
even dangerous results.

The fix itself is pretty straight-forward. There's a new
test in t0061 to cover this explicitly, and I've also added
a duplicate of the ENOENT test to ensure that we return the
correct errno for this case.

mingw: fix getcwd when the parent directory cannot... Anton Serbulov Tue, 23 Oct 2018 10:52:49 +0000 (03:52 -0700)

mingw: fix getcwd when the parent directory cannot be queried

`GetLongPathName()` function may fail when it is unable to query
the parent directory of a path component to determine the long name
for that component. It happens, because it uses `FindFirstFile()`
function for each next short part of path. The `FindFirstFile()`
requires `List Directory` and `Synchronize` desired access for a calling
process.

In case of lacking such permission for some part of path,
the `GetLongPathName()` returns 0 as result and `GetLastError()`
returns ERROR_ACCESS_DENIED.

`GetFinalPathNameByHandle()` function can help in such cases, because
it requires `Read Attributes` and `Synchronize` desired access to the
target path only.

The `GetFinalPathNameByHandle()` function was introduced on
`Windows Server 2008/Windows Vista`. So we need to load it dynamically.

`CreateFile()` parameters:
`lpFileName` = path to the current directory
`dwDesiredAccess` = 0 (it means `Read Attributes` and `Synchronize`)
`dwShareMode` = FILE_SHARE_READ | FILE_SHARE_WRITE | FILE_SHARE_DELETE
(it prevents `Sharing Violation`)
`lpSecurityAttributes` = NULL (default security attributes)
`dwCreationDisposition` = OPEN_EXISTING
(required to obtain a directory handle)
`dwFlagsAndAttributes` = FILE_FLAG_BACKUP_SEMANTICS
(required to obtain a directory handle)
`hTemplateFile` = NULL (when opening an existing file or directory,
`CreateFile` ignores this parameter)

The string that is returned by `GetFinalPathNameByHandle()` function
uses the \\?\ syntax. To skip the prefix and convert backslashes
to slashes, the `normalize_ntpath()` mingw function will be used.

Note: `GetFinalPathNameByHandle()` function returns a final path.
It is the path that is returned when a path is fully resolved.
For example, for a symbolic link named "C:\tmp\mydir" that points to
"D:\yourdir", the final path would be "D:\yourdir".

mingw: ensure `getcwd()` reports the correct case

When switching the current working directory, say, in PowerShell, it is
quite possible to use a different capitalization than the one that is
recorded on disk. While doing the same in `cmd.exe` adjusts the
capitalization magically, that does not happen in PowerShell so that
`getcwd()` returns the current directory in a different way than is
recorded on disk.

Typically this creates no problems except when you call

git log .

in a subdirectory called, say, "GIT/" but you switched to "Git/" and
your `getcwd()` reports the latter, then Git won't understand that you
wanted to see the history as per the `GIT/` subdirectory but it thinks you
wanted to see the history of some directory that may have existed in the
past (but actually never did).

So let's be extra careful to adjust the capitalization of the current
directory before working with it.

mingw: load system libraries the recommended way

When we access IPv6-related functions, we load the corresponding system
library using the `LoadLibrary()` function, which is not the recommended
way to load system libraries.

In practice, it does not make a difference: the `ws2_32.dll` library
containing the IPv6 functions is already loaded into memory, so
LoadLibrary() simply reuses the already-loaded library.

Still, recommended way is recommended way, so let's use that instead.

cocci: simplify "if (++u > 1)" to "if (u++)"

It is more common to use post-increment than pre-increment when the
side effect is the primary thing we want in our code and in C in
general (unlike C++).

Initializing a variable to 0, incrementing it every time we do
something, and checking if we have already done that thing to guard
the code to do that thing, is easier to understand when written

if (u++)
; /* we've done that! */
else
do_it(); /* just once. */

but if you try to use pre-increment, you end up with a less natural
looking

diff: don't attempt to strip prefix from absolute Windo... Johannes Sixt Fri, 19 Oct 2018 16:58:07 +0000 (18:58 +0200)

diff: don't attempt to strip prefix from absolute Windows paths

git diff can be invoked with absolute paths. Typically, this triggers
the --no-index case. Then the absolute paths remain in the file names
that are printed in the output.

There is one peculiarity, though: When the command is invoked from a
a sub-directory in a repository, then it is attempted to strip the
sub-directory from the beginning of relative paths. Yet, to detect a
relative path the code just checks for an initial forward slash.
This mistakes a Windows style path like "D:/base" as a relative path
and the output looks like this, for example:

D:\dir\test\one>git -P diff --numstat D:\dir\base D:\dir\diff
1 1 ir/{base => diff}/1.txt

where the correct output should be

D:\dir\test\one>git -P diff --numstat D:\dir\base D:\dir\diff
1 1 D:/dir/{base => diff}/1.txt

If the sub-directory where 'git diff' is invoked is sufficiently deep
that the prefix becomes longer than the path to be printed, then the
subsequent code accesses the path out of bounds.

Use is_absolute_path() to detect Windows style absolute paths.

One might wonder whether the check for a directory separator that
is visible in the patch context should be changed from == '/' to
is_dir_sep() or not. It turns out not to be necessary. That code
only ever investigates paths that have undergone pathspec
normalization, after which there are only forward slashes even on
Windows.

receive: denyCurrentBranch=updateinstead should not blindly update

The handling of receive.denyCurrentBranch=updateInstead was added to
a switch statement that handles other values of the variable, but
all the other case arms only checked a condition to reject the
attempted push, or let later logic in the same function to still
intervene, so that a push that does not fast-forward (which is
checked after the switch statement in question) is still rejected.

But the handling of updateInstead incorrectly took immediate effect,
without giving other checks a chance to intervene.

Instead of calling update_worktree() that causes the side effect
immediately, just note the fact that we will need to call the
function later, and first give other checks a chance to reject the
request. After the update-hook gets a chance to reject the push
(which happens as the last step in a series of checks), call
update_worktree() when we earlier detected the need to.

pack-objects (mingw): initialize `packing_data` mutex in the correct spot

In 9ac3f0e5b3e4 (pack-objects: fix performance issues on packing large
deltas, 2018-07-22), a mutex was introduced that is used to guard the
call to set the delta size. This commit even added code to initialize
it, but at an incorrect spot: in `init_threaded_search()`, while the
call to `oe_set_delta_size()` (and hence to `packing_data_lock()`) can
happen in the call chain `check_object()` <- `get_object_details()` <-
`prepare_pack()` <- `cmd_pack_objects()`, which is long before the
`prepare_pack()` function calls `ll_find_deltas()` (which initializes
the threaded search).

Another tell-tale that the mutex was initialized in an incorrect spot is
that the function to initialize it lives in builtin/, while the code
that uses the mutex is defined in a libgit.a header file.

Let's use a more appropriate function: `prepare_packing_data()`, which
not only lives in libgit.a, but *has* to be called before the
`packing_data` struct is used that contains that mutex.

When pushing into a repository that borrows its objects from an

sometimes is detrimental when the number of refs in the alternate

Merge branch 'jt/avoid-ls-refs'Junio C Hamano Fri, 19 Oct 2018 04:34:07 +0000 (13:34 +0900)

Merge branch 'jt/avoid-ls-refs'

Over some transports, fetching objects with an exact commit object
name can be done without first seeing the ref advertisements. The
code has been optimized to exploit this.

* jt/avoid-ls-refs:
fetch: do not list refs if fetching only hashes
transport: list refs before fetch if necessary
transport: do not list refs if possible
transport: allow skipping of ref listing

Merge branch 'ds/commit-graph-leakfix'Junio C Hamano Fri, 19 Oct 2018 04:34:07 +0000 (13:34 +0900)

Merge branch 'ds/commit-graph-leakfix'

Code clean-up.

* ds/commit-graph-leakfix:
commit-graph: reduce initial oid allocation
builtin/commit-graph.c: UNLEAK variables
commit-graph: clean up leaked memory during write

Merge branch 'jt/non-blob-lazy-fetch'Junio C Hamano Fri, 19 Oct 2018 04:34:07 +0000 (13:34 +0900)

Merge branch 'jt/non-blob-lazy-fetch'

A partial clone that is configured to lazily fetch missing objects
will on-demand issue a "git fetch" request to the originating
repository to fill not-yet-obtained objects. The request has been
optimized for requesting a tree object (and not the leaf blob
objects contained in it) by telling the originating repository that
no blobs are needed.

* jt/non-blob-lazy-fetch:
fetch-pack: exclude blobs when lazy-fetching trees
fetch-pack: avoid object flags if no_dependents

Merge branch 'pw/diff-color-moved-ws-fix'Junio C Hamano Fri, 19 Oct 2018 04:34:06 +0000 (13:34 +0900)

Merge branch 'pw/diff-color-moved-ws-fix'

Various fixes to "diff --color-moved-ws".

* pw/diff-color-moved-ws-fix:
diff --color-moved: fix a memory leak
diff --color-moved-ws: fix another memory leak
diff --color-moved-ws: fix a memory leak
diff --color-moved-ws: fix out of bounds string access
diff --color-moved-ws: fix double free crash

Merge branch 'rs/oidset-on-khash'Junio C Hamano Fri, 19 Oct 2018 04:34:06 +0000 (13:34 +0900)

Merge branch 'rs/oidset-on-khash'

The oidset API was built on top of the oidmap API which in turn is
on the hashmap API. Replace the implementation to build on top of
the khash API and gain performance.

* rs/oidset-on-khash:
oidset: uninline oidset_init()
oidset: use khash
khash: factor out kh_release_*
fetch-pack: load tip_oids eagerly iff needed
fetch-pack: factor out is_unmatched_ref()

Merge branch 'rs/grep-no-recursive'Junio C Hamano Fri, 19 Oct 2018 04:34:05 +0000 (13:34 +0900)

Merge branch 'rs/grep-no-recursive'

Unlike "grep", "git grep" by default recurses to the whole tree.
The command learned "git grep --recursive" option, so that "git
grep --no-recursive" can serve as a synonym to setting the
max-depth to 0.

* rs/grep-no-recursive:
grep: add -r/--[no-]recursive

Merge branch 'nd/help-commands-verbose-by-default'Junio C Hamano Fri, 19 Oct 2018 04:34:05 +0000 (13:34 +0900)

Merge branch 'nd/help-commands-verbose-by-default'

"git help -a" and "git help -av" give different pieces of
information, and generally the "verbose" version is more friendly
to the new users. "git help -a" by default now uses the more
verbose output (with "--no-verbose", you can go back to the
original). Also "git help -av" now lists aliases and external
commands, which it did not used to.

* nd/help-commands-verbose-by-default:
help -a: improve and make --verbose default

Merge branch 'sm/show-superproject-while-conflicted'

A corner-case bugfix.

* sm/show-superproject-while-conflicted:
rev-parse: --show-superproject-working-tree should work during a merge

Merge branch 'jt/fetch-tips-in-partial-clone'Junio C Hamano Fri, 19 Oct 2018 04:34:04 +0000 (13:34 +0900)

Merge branch 'jt/fetch-tips-in-partial-clone'

"git fetch $repo $object" in a partial clone did not correctly
fetch the asked-for object that is referenced by an object in
promisor packfile, which has been fixed.

* jt/fetch-tips-in-partial-clone:
fetch: in partial clone, check presence of targets
connected: document connectivity in partial clones

Merge branch 'nd/status-refresh-progress'Junio C Hamano Fri, 19 Oct 2018 04:34:03 +0000 (13:34 +0900)

Merge branch 'nd/status-refresh-progress'

"git status" learns to show progress bar when refreshing the index
takes a long time.

* nd/status-refresh-progress:
status: show progress bar if refreshing the index takes too long

Merge branch 'bp/read-cache-parallel'Junio C Hamano Fri, 19 Oct 2018 04:34:03 +0000 (13:34 +0900)

Merge branch 'bp/read-cache-parallel'

A new extension to the index file has been introduced, which allows
the file to be read in parallel.

* bp/read-cache-parallel:
read-cache: load cache entries on worker threads
ieot: add Index Entry Offset Table (IEOT) extension
read-cache: load cache extensions on a worker thread
config: add new index.threads config setting
eoie: add End of Index Entry (EOIE) extension
read-cache: clean up casting and byte decoding
read-cache.c: optimize reading index format v4
