Although "git worktree add" learned to run the 'post-checkout' hook in
ade546be47 (worktree: invoke post-checkout hook, 2017-12-07), it
neglected to change to the directory of the newly-created worktree
before running the hook. Instead, the hook runs within the directory
from which the "git worktree add" command itself was invoked, which
effectively neuters the hook since it knows nothing about the new
worktree directory.
Further, ade546be47 failed to sanitize the environment before running
the hook, which means that user-assigned values of GIT_DIR and
GIT_WORK_TREE could mislead the hook about the location of the new
worktree. In the case of "git worktree add" being run from a bare
repository, the GIT_DIR="." assigned by Git itself leaks into the hook's
environment and breaks Git commands; this is so even when the working
directory is correctly changed to the new worktree before the hook runs
since ".", relative to the new worktree directory, does not point at the
bare repository.
Fix these problems by (1) changing to the new worktree's directory
before running the hook, and (2) sanitizing the environment of GIT_DIR
and GIT_WORK_TREE so hooks can't be confused by misleading values.
Enhance the t2025 'post-checkout' tests to verify that the hook is
indeed run within the correct directory and that Git commands invoked by
the hook compute Git-dir and top-level worktree locations correctly.
While at it, also add two new tests: (1) verify that the hook is run
within the correct directory even when the new worktree is created from
a sibling worktree (as opposed to the main worktree); (2) verify that
the hook is provided with correct context when the new worktree is
created from a bare repository (test provided by Lars Schneider).
Implementation Notes:
Rather than sanitizing the environment of GIT_DIR and GIT_WORK_TREE, an
alternative would be to set them explicitly, as is already done for
other Git commands run internally by "git worktree add". This patch opts
instead to sanitize the environment in order to clearly document that
the worktree is fully functional by the time the hook is run, thus does
not require special environmental overrides.
The hook is run manually, rather than via run_hook_le(), since it needs
to change the working directory to that of the worktree, and
run_hook_le() does not provide such functionality. As this is a one-off
case, adding 'run_hook' overloads which allow the directory to be set
does not seem warranted at this time.

git-clone and git-checkout both invoke the post-checkout hook following
a successful checkout, yet git-worktree neglects to do so even though it
too "checks out" the worktree. Fix this oversight.
Implementation note: The newly-created worktree may reference a branch
or be detached. In the latter case, a commit lookup is performed, though
the result is used only in a boolean sense to (a) determine if the
commit actually exists, and (b) assign either the branch name or commit
ID to HEAD. Since the post-commit hook needs to know the ID of the
checked-out commit, the lookup now needs to be done in all cases, rather
than only when detached. Consequently, a new boolean is needed to handle
(b) since the lookup result itself can no longer perform that role.

The ssh-variant 'simple' introduced earlier broke existing
installations by not passing --port/-4/-6 and not diagnosing an
attempt to pass these as an error. Instead, default to
automatically detect how compatible the GIT_SSH/GIT_SSH_COMMAND is
to OpenSSH convention and then error out an invocation to make it
easier to diagnose connection errors.
* jn/ssh-wrappers:
connect: correct style of C-style comment
ssh: 'simple' variant does not support --port
ssh: 'simple' variant does not support -4/-6
ssh: 'auto' variant to select between 'ssh' and 'simple'
connect: split ssh option computation to its own function
connect: split ssh command line options into separate function
connect: split git:// setup into a separate function
connect: move no_fork fallback to git_tcp_connect
ssh test: make copy_ssh_wrapper_as clean up after itself

When trying to connect to an ssh:// URL with port explicitly specified
and the ssh command configured with GIT_SSH does not support such a
setting, it is less confusing to error out than to silently suppress
the port setting and continue.
This requires updating the GIT_SSH setting in t5603-clone-dirname.sh.
That test is about the directory name produced when cloning various
URLs. It uses an ssh wrapper that ignores all its arguments but does
not declare that it supports a port argument; update it to set
GIT_SSH_VARIANT=ssh to do so. (Real-life ssh wrappers that pass a
port argument to OpenSSH would also support -G and would not require
such an update.)

Android's "repo" tool is a tool for managing a large codebase
consisting of multiple smaller repositories, similar to Git's
submodule feature. Starting with Git 94b8ae5a (ssh: introduce a
'simple' ssh variant, 2017-10-16), users noticed that it stopped
handling the port in ssh:// URLs.
The cause: when it encounters ssh:// URLs, repo pre-connects to the
server and sets GIT_SSH to a helper ".repo/repo/git_ssh" that reuses
that connection. Before 94b8ae5a, the helper was assumed to support
OpenSSH options for lack of a better guess and got passed a -p option
to set the port. After that patch, it uses the new default of a
simple helper that does not accept an option to set the port.
The next release of "repo" will set GIT_SSH_VARIANT to "ssh" to avoid
that. But users of old versions and of other similar GIT_SSH
implementations would not get the benefit of that fix.
So update the default to use OpenSSH options again, with a twist. As
observed in 94b8ae5a, we cannot assume that $GIT_SSH always handles
OpenSSH options: common helpers such as travis-ci's dpl[*] are
configured using GIT_SSH and do not accept OpenSSH options. So make
the default a new variant "auto", with the following behavior:
1. First, check for a recognized basename, like today.
2. If the basename is not recognized, check whether $GIT_SSH supports
OpenSSH options by running
$GIT_SSH -G <options> <host>
This returns status 0 and prints configuration in OpenSSH if it
recognizes all <options> and returns status 255 if it encounters
an unrecognized option. A wrapper script like
exec ssh -- "$@"
would fail with
ssh: Could not resolve hostname -g: Name or service not known
, correctly reflecting that it does not support OpenSSH options.
The command is run with stdin, stdout, and stderr redirected to
/dev/null so even a command that expects a terminal would exit
immediately.
3. Based on the result from step (2), behave like "ssh" (if it
succeeded) or "simple" (if it failed).
This way, the default ssh variant for unrecognized commands can handle
both the repo and dpl cases as intended.
This autodetection has been running on Google workstations since
2017-10-23 with no reported negative effects.

Simplify by not allowing the copied ssh wrapper to persist between
tests. This way, tests can be safely reordered, added, and removed
with less fear of hidden side effects.
This also avoids having to call setup_ssh_wrapper to restore the value
of GIT_SSH after this battery of tests, since it means each test will
restore it individually.
Noticed because on Windows, if `uplink.exe` exists, the MSYS2 Bash
will overwrite that when redirecting via `>uplink`. A proposed test
wrote a script to 'uplink' after a previous test created uplink.exe
using copy_ssh_wrapper_as, so the script written with '>uplink' had
the wrong filename and failed.

A new mechanism to upgrade the wire protocol in place is proposed
and demonstrated that it works with the older versions of Git
without harming them.
* bw/protocol-v1:
Documentation: document Extra Parameters
ssh: introduce a 'simple' ssh variant
i5700: add interop test for protocol transition
http: tell server that the client understands v1
connect: tell server that the client understands v1
connect: teach client to recognize v1 server response
upload-pack, receive-pack: introduce protocol version 1
daemon: recognize hidden request arguments
protocol: introduce protocol extension mechanisms
pkt-line: add packet_write function
connect: in ref advertisement, shallows are last

When using the 'ssh' transport, the '-o' option is used to specify an
environment variable which should be set on the remote end. This allows
git to send additional information when contacting the server,
requesting the use of a different protocol version via the
'GIT_PROTOCOL' environment variable like so: "-o SendEnv=GIT_PROTOCOL".
Unfortunately not all ssh variants support the sending of environment
variables to the remote end. To account for this, only use the '-o'
option for ssh variants which are OpenSSH compliant. This is done by
checking that the basename of the ssh command is 'ssh' or the ssh
variant is overridden to be 'ssh' (via the ssh.variant config).
Other options like '-p' and '-P', which are used to specify a specific
port to use, or '-4' and '-6', which are used to indicate that IPV4 or
IPV6 addresses should be used, may also not be supported by all ssh
variants.
Currently if an ssh command's basename wasn't 'plink' or
'tortoiseplink' git assumes that the command is an OpenSSH variant.
Since user configured ssh commands may not be OpenSSH compliant, tighten
this constraint and assume a variant of 'simple' if the basename of the
command doesn't match the variants known to git. The new ssh variant
'simple' will only have the host and command to execute ([username@]host
command) passed as parameters to the ssh command.
Update the Documentation to better reflect the command-line options sent
to ssh commands based on their variant.

Teach the connection logic to tell a serve that it understands protocol
v1. This is done in 2 different ways for the builtin transports, both
of which ultimately set 'GIT_PROTOCOL' to 'version=1' on the server.
1. git://
A normal request to git-daemon is structured as
"command path/to/repo\0host=..\0" and due to a bug introduced in
49ba83fb6 (Add virtualization support to git-daemon, 2006-09-19) we
aren't able to place any extra arguments (separated by NULs) besides
the host otherwise the parsing of those arguments would enter an
infinite loop. This bug was fixed in 73bb33a94 (daemon: Strictly
parse the "extra arg" part of the command, 2009-06-04) but a check
was put in place to disallow extra arguments so that new clients
wouldn't trigger this bug in older servers.
In order to get around this limitation git-daemon was taught to
recognize additional request arguments hidden behind a second
NUL byte. Requests can then be structured like:
"command path/to/repo\0host=..\0\0version=1\0key=value\0".
git-daemon can then parse out the extra arguments and set
'GIT_PROTOCOL' accordingly.
By placing these extra arguments behind a second NUL byte we can
skirt around both the infinite loop bug in 49ba83fb6 (Add
virtualization support to git-daemon, 2006-09-19) as well as the
explicit disallowing of extra arguments introduced in 73bb33a94
(daemon: Strictly parse the "extra arg" part of the command,
2009-06-04) because both of these versions of git-daemon check for a
single NUL byte after the host argument before terminating the
argument parsing.
2. ssh://, file://
Set 'GIT_PROTOCOL' environment variable with the desired protocol
version. With the file:// transport, 'GIT_PROTOCOL' can be set
explicitly in the locally running git-upload-pack or git-receive-pack
processes. With the ssh:// transport and OpenSSH compliant ssh
programs, 'GIT_PROTOCOL' can be sent across ssh by using '-o
SendEnv=GIT_PROTOCOL' and having the server whitelist this
environment variable.

`git stash push -m foo` uses "foo" as the message for the stash. But
`git stash push -m"foo"` does not parse successfully. Similarly
`git stash push --message="My stash message"` also fails. The stash
documentation doesn't suggest this syntax should work, but gitcli
does and my fingers have learned this pattern long ago for `commit`.
Teach `git stash` to parse -mFoo and --message=Foo the same as `git
commit` would do. Even though it's an internal function, add
similar support to create_stash() for consistency.

Internaly we use 0{40} as a placeholder object name to signal the
codepath that there is no such object (e.g. the fast-forward check
while "git fetch" stores a new remote-tracking ref says "we know
there is no 'old' thing pointed at by the ref, as we are creating
it anew" by passing 0{40} for the 'old' side), and expect that a
codepath to locate an in-core object to return NULL as a sign that
the object does not exist. A look-up for an object that does not
exist however is quite costly with a repository with large number
of packfiles. This access pattern has been optimized.

Since fetch often deals with object-ids we don't have (yet),
it's an easy mistake for it to use a function like
parse_object() that gives the correct result (e.g., NULL)
but does so very slowly (because after failing to find the
object, we re-scan the pack directory looking for new
packs).
The regular test suite won't catch this because the end
result is correct, but we would want to know about
performance regressions, too. Let's add a test to the
regression suite.
Note that this uses a synthetic repository that has a large
number of packs. That's not ideal, as it means we're not
testing what "normal" users see (in fact, some of these
problems have existed for ages without anybody noticing
simply because a rescan on a normal repository just isn't
that expensive).
So what we're really looking for here is the spike you'd
notice in a pathological case (a lot of unknown objects
coming into a repo with a lot of packs). If that's fast,
then the normal cases should be, too.
Note that the test also makes liberal use of $MODERN_GIT for
setup; some of these regressions go back a ways, and we
should be able to use it to find the problems there.

We currently use fast-import only to create a large number
of objects, and then run O(n) invocations of pack-objects to
turn them into packs.
We can do this faster by just asking fast-import to

not to turn loose tiny packs).

Add --expiry-date as a data-type for config files when
'git config --get' is used. This will return any relative
or fixed dates from config files as timestamps.
This is useful for scripts (e.g. gc.reflogexpire) that work
with timestamps so that '2.weeks' can be converted to a format
acceptable by those scripts/functions.
Following the convention of git_config_pathname(), move
the helper function required for this feature from
builtin/reflog.c to builtin/config.c where other similar
functions exist (e.g. for --bool or --path), and match
the order of parameters with other functions (i.e. output
pointer as first parameter).

When tests are run for a subsection defined in a config file, it is
better if the results for the current subsection are not overwritting
the results of a previous subsection.
So let's store the results for a subsection in a subdirectory of
"test-results/" with the subsection name.
The aggregate.perl, when it is run for a subsection, should then
aggregate the results found in "test-results/$GIT_PERF_SUBSECTION/".

Let's make it easy to store some parameters in a config
file and to pass them to the run script.

argument of the '--config' option. This variable is not

"git checkout --recursive" may overwrite and rewind the history of
the branch that happens to be checked out in submodule
repositories, which might not be desirable. Detach the HEAD but
still allow the recursive checkout to succeed in such a case.

When a submodule is on a branch and in its superproject you run a
recursive checkout, the branch of the submodule is updated to what the
superproject checks out. This is very unexpected in the current model of
Git as e.g. 'submodule update' always detaches the submodule HEAD.
Despite having plans to have submodule HEADS not detached in the future,
the current behavior is really bad as it doesn't match user expectations
and it is not checking for loss of commits (only to be recovered via the
reflog).
Detach the HEAD unconditionally in the submodule when updating it.

Non-empty lines before a function definition are most likely comments
for that function and thus relevant. Include them in function context.
Such a non-empty line might also belong to the preceding function if
there is no separating blank line. Stop extending the context upwards
also at the next function line to make sure only one extra function body
is shown at most.

The check for function context (-W) together with user-defined function
line patterns reuses hello.c and pretends it's written in a language in
which function lines contain either "printf" or a trailing curly brace.
That's a bit obscure.
Make the test easier to read by adding a small PowerShell script, using
a simple, but meaningful expression, and separating out checks for
different aspects into dedicated tests instead of simply matching the
whole output byte for byte.
Also include a test for showing comments before function lines like git

When showing function context it would be helpful to show comments
immediately before declarations, as they are most likely relevant.
Add a test for that, but without specifying the choice of lines too
rigidly in the test---we may want to stop before and not include
"/*" in the future, for example.

"git branch --list" learned to show its output through the pager by
default when the output is going to a terminal, which is controlled
by the pager.branch configuration variable. This is similar to a
recent change to "git tag --list".

branch: change default of `pager.branch` to "on"

This is similar to ff1e72483 (tag: change default of `pager.tag` to
"on", 2017-08-02) and is safe now that we do not consider `pager.branch`
at all when we are not listing branches. This change will help with
listing many branches, but will not hurt users of `git branch
--edit-description` as it would have before the previous commit.

Similar to de121ffe5 (tag: respect `pager.tag` in list-mode only,
2017-08-02), use the DELAY_PAGER_CONFIG-mechanism to only respect
`pager.branch` when we are listing branches.
We have two possibilities of generalizing what that earlier commit made
to `git tag`. One is to interpret, e.g., --set-upstream-to as "it does
not use an editor, so we should page". Another, the one taken by this
commit, is to say "it does not list, so let's not page". That is in line
with the approach of the series on `pager.tag` and in particular the
wording in Documentation/git-tag.txt, which this commit reuses for
git-branch.txt.
This fixes the failing test added in the previous commit. Also adapt the
test for whether `git branch --set-upstream-to` respects `pager.branch`.

The next couple of commits will change how `git branch` handles
`pager.branch`, similar to how de121ffe5 (tag: respect `pager.tag` in
list-mode only, 2017-08-02) and ff1e72483 (tag: change default of
`pager.tag` to "on", 2017-08-02) changed `git tag`.
Add tests in this area to make sure that we don't regress and so that
the upcoming commits can be made clearer by adapting the tests. Add some
tests for `--list` (implied), one for `--edit-description`, and one for
`--set-upstream-to` as a representative of "something other than the
first two".
In particular, use `test_expect_failure` to document that we currently
respect the pager-configuration with `--edit-description`. The current
behavior is buggy since the pager interferes with the editor and makes
the end result completely broken. See also b3ee740c8 (t7006: add tests
for how git tag paginates, 2017-08-02).

strbuf_check_branch_ref() is the central place where many codepaths
see if a proposed name is suitable for the name of a branch. It was
designed to allow us to get stricter than the check_refname_format()
check used for refnames in general, and we already use it to reject
a branch whose name begins with a '-'. The function gets a strbuf
and a string "name", and returns non-zero if the name is not
appropriate as the name for a branch. When the name is good, it
places the full refname for the branch with the proposed name in the
strbuf before it returns.
However, it turns out that one caller looks at what is in the strbuf
even when the function returns an error. Make the function populate
the strbuf even when it returns an error. That way, when "-dash" is
given as name, "refs/heads/-dash" is placed in the strbuf when
returning an error to copy_or_rename_branch(), which notices that
the user is trying to recover with "git branch -m -- -dash dash" to
rename "-dash" to "dash".
While at it, use the same mechanism to also reject "HEAD" as a
branch name.
