perl: call timegm and timelocal with 4-digit year

Amazingly, timegm(gmtime(0)) is only 0 before 2020 because perl's
timegm deviates from GNU timegm(3) in how it handles years.

man Time::Local says

Whenever possible, use an absolute four digit year instead.

with a detailed explanation about ambiguity of 2-digit years above that.

Even though this ambiguity is error-prone with >50% of users getting it
wrong, it has been like this for 20+ years, so we just use 4-digit years
everywhere to be on the safe side.

We add some extra logic to cvsimport because it allows 2-digit year
input and interpreting an 18 as 1918 can be avoided easily and safely.

subtree: fix add and pull for GPG-signed commits

If log.showsignature is true (or --show-signature is passed) while
performing a `subtree add` or `subtree pull`, the command fails.

toptree_for_commit() calls `log` and passes the output to `commit-tree`.
If this output shows the GPG signature data, `commit-tree` throws a
fatal error.

This commit fixes the issue by adding --no-show-signature to `log` calls
in a few places, as well as using the more appropriate `rev-parse`
instead where possible.

ref-filter: make "--contains <id>" less chatty if <id> is invalid

Some git commands which use --contains <id> print the whole
help text if <id> is invalid. It should only show the error
message instead.

This patch applies to "git tag", "git branch", "git for-each-ref".

This bug was a side effect of looking up the commit in option
parser callback. When a error occurs in the option parser, the
full usage is shown. To fix this bug, the part related to
looking up the commit was moved outside of the option parser
to the ref-filter module.

Basically, the option parser only parses strings that represent
commits and the ref-filter performs the commit look-up. If an
error occurs during the option parsing, then it must be an invalid
argument and the user should be informed of usage, but if a error
occurs during ref-filtering, then it is a problem with the
argument.

grep: move grep_source_init outside critical section

grep_source_init typically does three strdup()s, and in the threaded
case, the call from add_work() happens while holding grep_mutex.

We can thus reduce the time we hold grep_mutex by moving the
grep_source_init() call out of add_work(), and simply have add_work()
copy the initialized structure to the available slot in the todo
array.

This also simplifies the prototype of add_work(), since it no longer
needs to duplicate all the parameters of grep_source_init(). In the
callers of add_work(), we get to reduce the amount of code duplicated in
the threaded and non-threaded cases slightly (avoiding repeating the
long "GREP_SOURCE_OID, pathbuf.buf, path, oid" argument list); a
subsequent cleanup patch will make that even more so.

rebase -i: introduce --recreate-merges=[no-]rebase... Johannes Schindelin Fri, 23 Feb 2018 12:39:54 +0000 (13:39 +0100)

rebase -i: introduce --recreate-merges=[no-]rebase-cousins

This one is a bit tricky to explain, so let's try with a diagram:

C
/ \
A - B - E - F
\ /
D

To illustrate what this new mode is all about, let's consider what
happens upon `git rebase -i --recreate-merges B`, in particular to
the commit `D`. So far, the new branch structure would be:

--- C' --
/ \
A - B ------ E' - F'
\ /
D'

This is not really preserving the branch topology from before! The
reason is that the commit `D` does not have `B` as ancestor, and
therefore it gets rebased onto `B`.

This is unintuitive behavior. Even worse, when recreating branch
structure, most use cases would appear to want cousins *not* to be
rebased onto the new base commit. For example, Git for Windows (the
heaviest user of the Git garden shears, which served as the blueprint
for --recreate-merges) frequently merges branches from `next` early, and
these branches certainly do *not* want to be rebased. In the example
above, the desired outcome would look like this:

--- C' --
/ \
A - B ------ E' - F'
\ /
-- D' --

Let's introduce the term "cousins" for such commits ("D" in the
example), and let's not rebase them by default, introducing the new
"rebase-cousins" mode for use cases where they should be rebased.

Similar to the `preserve` mode simply passing the `--preserve-merges`

This will allow users to conveniently rebase non-trivial commit

sequencer: handle post-rewrite for merge commandsJohannes Schindelin Fri, 23 Feb 2018 12:39:07 +0000 (13:39 +0100)

sequencer: handle post-rewrite for merge commands

In the previous patches, we implemented the basic functionality of the
`git rebase -i --recreate-merges` command, in particular the `merge`
command to create merge commits in the sequencer.

The interactive rebase is a lot more these days, though, than a simple
cherry-pick in a loop. For example, it calls the post-rewrite hook (if
any) after rebasing with a mapping of the old->new commits.

This patch implements the post-rewrite handling for the `merge` command
we just introduced. The other commands that were added recently (`label`
and `reset`) do not create new commits, therefore post-rewrite do not
need to handle them.

rebase: introduce the --recreate-merges optionJohannes Schindelin Fri, 23 Feb 2018 12:38:24 +0000 (13:38 +0100)

rebase: introduce the --recreate-merges option

Once upon a time, this here developer thought: wouldn't it be nice if,
say, Git for Windows' patches on top of core Git could be represented as
a thicket of branches, and be rebased on top of core Git in order to
maintain a cherry-pick'able set of patch series?

The original attempt to answer this was: git rebase --preserve-merges.

However, that experiment was never intended as an interactive option,
and it only piggy-backed on git rebase --interactive because that
command's implementation looked already very, very familiar: it was
designed by the same person who designed --preserve-merges: yours truly.

Some time later, some other developer (I am looking at you, Andreas!
;-)) decided that it would be a good idea to allow --preserve-merges to
be combined with --interactive (with caveats!) and the Git maintainer
(well, the interim Git maintainer during Junio's absence, that is)
agreed, and that is when the glamor of the --preserve-merges design
started to fall apart rather quickly and unglamorously.

The reason? In --preserve-merges mode, the parents of a merge commit (or
for that matter, of *any* commit) were not stated explicitly, but were
*implied* by the commit name passed to the `pick` command.

This made it impossible, for example, to reorder commits. Not to mention
to flatten the branch topology or, deity forbid, to split topic branches
into two.

Alas, these shortcomings also prevented that mode (whose original
purpose was to serve Git for Windows' needs, with the additional hope
that it may be useful to others, too) from serving Git for Windows'
needs.

Five years later, when it became really untenable to have one unwieldy,
big hodge-podge patch series of partly related, partly unrelated patches
in Git for Windows that was rebased onto core Git's tags from time to
time (earning the undeserved wrath of the developer of the ill-fated
git-remote-hg series that first obsoleted Git for Windows' competing
approach, only to be abandoned without maintainer later) was really
untenable, the "Git garden shears" were born [*1*/*2*]: a script,
piggy-backing on top of the interactive rebase, that would first
determine the branch topology of the patches to be rebased, create a
pseudo todo list for further editing, transform the result into a real
todo list (making heavy use of the `exec` command to "implement" the
missing todo list commands) and finally recreate the patch series on
top of the new base commit.

That was in 2013. And it took about three weeks to come up with the
design and implement it as an out-of-tree script. Needless to say, the
implementation needed quite a few years to stabilize, all the while the
design itself proved itself sound.

With this patch, the goodness of the Git garden shears comes to `git
rebase -i` itself. Passing the `--recreate-merges` option will generate
a todo list that can be understood readily, and where it is obvious
how to reorder commits. New branches can be introduced by inserting
`label` commands and calling `merge <label>`. And once this mode will
have become stable and universally accepted, we can deprecate the design
mistake that was `--preserve-merges`.

rebase-helper --make-script: introduce a flag to recreate merges

The sequencer just learned new commands intended to recreate branch
structure (similar in spirit to --preserve-merges, but with a
substantially less-broken design).

Let's allow the rebase--helper to generate todo lists making use of
these commands, triggered by the new --recreate-merges option. For a
commit topology like this (where the HEAD points to C):

- A - B - C
\ /
D

the generated todo list would look like this:

# branch D
pick 0123 A
label branch-point
pick 1234 D
label D

reset branch-point
pick 2345 B
merge -C 3456 D # C

To keep things simple, we first only implement support for merge commits
with exactly two parents, leaving support for octopus merges to a later
patch in this patch series.

As a special, hard-coded label, all merge-recreating todo lists start with
the command `label onto` so that we can later always refer to the revision
onto which everything is rebased.

sequencer: fast-forward merge commits, if possible

Just like with regular `pick` commands, if we are trying to recreate a
merge commit, we now test whether the parents of said commit match HEAD
and the commits to be merged, and fast-forward if possible.

This is not only faster, but also avoids unnecessary proliferation of
new objects.

sequencer: introduce the `merge` commandJohannes Schindelin Fri, 23 Feb 2018 12:37:22 +0000 (13:37 +0100)

sequencer: introduce the `merge` command

This patch is part of the effort to reimplement `--preserve-merges` with
a substantially improved design, a design that has been developed in the
Git for Windows project to maintain the dozens of Windows-specific patch
series on top of upstream Git.

The previous patch implemented the `label` and `reset` commands to label
commits and to reset to labeled commits. This patch adds the `merge`
command, with the following syntax:

merge [-C <commit>] <rev> # <oneline>

The <commit> parameter in this instance is the *original* merge commit,
whose author and message will be used for the merge commit that is about
to be created.

The <rev> parameter refers to the (possibly rewritten) revision to
merge. Let's see an example of a todo list:

label onto

# Branch abc
reset onto
pick deadbeef Hello, world!
label abc

reset onto
pick cafecafe And now for something completely different
merge -C baaabaaa abc # Merge the branch 'abc' into master

To edit the merge commit's message (a "reword" for merges, if you will),
use `-c` (lower-case) instead of `-C`; this convention was borrowed from
`git commit` that also supports `-c` and `-C` with similar meanings.

To create *new* merges, i.e. without copying the commit message from an
existing commit, simply omit the `-C <commit>` parameter (which will
open an editor for the merge message):

merge abc

This comes in handy when splitting a branch into two or more branches.

Note: this patch only adds support for recursive merges, to keep things
simple. Support for octopus merges will be added later in a separate
patch series, support for merges using strategies other than the
recursive merge is left for the future.

sequencer: introduce new commands to reset the revisionJohannes Schindelin Fri, 23 Feb 2018 12:37:01 +0000 (13:37 +0100)

sequencer: introduce new commands to reset the revision

In the upcoming commits, we will teach the sequencer to recreate merges.
This will be done in a very different way from the unfortunate design of
`git rebase --preserve-merges` (which does not allow for reordering
commits, or changing the branch topology).

The main idea is to introduce new todo list commands, to support
labeling the current revision with a given name, resetting the current
revision to a previous state, and merging labeled revisions.

This idea was developed in Git for Windows' Git garden shears (that are
used to maintain the "thicket of branches" on top of upstream Git), and
this patch is part of the effort to make it available to a wider
audience, as well as to make the entire process more robust (by
implementing it in a safe and portable language rather than a Unix shell
script).

This commit implements the commands to label, and to reset to, given
revisions. The syntax is:

label <name>
reset <name>

Internally, the `label <name>` command creates the ref
`refs/rewritten/<name>`. This makes it possible to work with the labeled
revisions interactively, or in a scripted fashion (e.g. via the todo
list command `exec`).

These temporary refs are removed upon sequencer_remove_state(), so that
even a `git rebase --abort` cleans them up.

We disallow '#' as label because that character will be used as separator
in the upcoming `merge` command.

Later in this patch series, we will mark the `refs/rewritten/` refs as
worktree-local, to allow for interactive rebases to be run in parallel in
worktrees linked to the same repository.

In gitsubmodules.txt, a few non-ASCII apostrophes are used to spell
possessive, e.g. "submodule's". These unfortunately are not
rendered at https://git-scm.com/docs/gitsubmodules correctly by the
renderer used there.

Use ASCII apostrophes instead to work around the problem. It also
is good to be consistent, as there are possessives spelled with
ASCII apostrophes.

t: send verbose test-helper output to fd 4Jeff King Thu, 22 Feb 2018 06:48:37 +0000 (01:48 -0500)

t: send verbose test-helper output to fd 4

Test helper functions like test_must_fail may produce
messages to stderr when they see a problem. When the tests
are run with "--verbose", this ends up on the test script's
stderr, and the user can read it.

But there's a problem. Some tests record stderr as part of
the test, like:

test_must_fail git foo 2>output &&
test_i18ngrep expected.message output

In this case the error text goes into "output". This makes
the --verbose output less useful (it also means we might
accidentally match it in the second, though in practice we
tend to produce these messages only on error, so we'd abort
the test when the first command fails).

Let's instead send this user-facing output directly to
descriptor 4, which always points to the original stderr (or
/dev/null in non-verbose mode). And it's already forbidden
to redirect descriptor 4, since we use it for BASH_XTRACEFD,
as explained in 9be795fbce (t5615: avoid re-using descriptor
4, 2017-12-08).

revision: drop --show-all option

This was an undocumented debugging aid that does not seem to
have come in handy in the past decade, judging from its lack
of mentions on the mailing list.

Let's drop it in the name of simplicity. This is morally a
revert of 3131b71301 (Add "--show-all" revision walker flag
for debugging, 2008-02-09), but note that I did leave in the
mapping of UNINTERESTING to "^" in get_revision_mark(). I
don't think this would be possible to trigger with the
current code, but it's the only sensible marker.

We'll skip the usual deprecation period because this was
explicitly a debugging aid that was never documented.

commit: drop uses of get_cached_commit_buffer()Jeff King Wed, 21 Feb 2018 23:13:38 +0000 (18:13 -0500)

commit: drop uses of get_cached_commit_buffer()

The "--show-all" revision option shows UNINTERESTING
commits. Some of these commits may be unparsed when we try
to show them (since we may or may not need to walk their
parents to fulfill the request).

Commit 3131b71301 (Add "--show-all" revision walker flag for
debugging, 2008-02-09) resolved this by just skipping
pretty-printing for commits without their object contents
cached, saying:

Because we now end up listing commits we may not even have been parsed
at all "show_log" and "show_commit" need to protect against commits
that don't have a commit buffer entry.

That was the easy fix to avoid the pretty-printer segfaulting,
but:

1. It doesn't work for all formats. E.g., --oneline
prints the oid for each such commit but not a trailing
newline, leading to jumbled output.

2. It only affects some commits, depending on whether we
happened to parse them or not (so if they were at the
tip of an UNINTERESTING starting point, or if we
happened to traverse over them, you'd see more data).

3. It unncessarily ties the decision to show the verbose
header to whether the commit buffer was cached. That
makes it harder to change the logic around caching
(e.g., if we could traverse without actually loading
the full commit objects).

These days it's safe to feed such a commit to the
pretty-print code. Since be5c9fb904 (logmsg_reencode: lazily
load missing commit buffers, 2013-01-26), we'll load it on
demand in such a case. So let's just always show the verbose
headers.

This does change the behavior of plumbing, but:

a. The --show-all option was explicitly introduced as a
debugging aid, and was never documented (and has rarely
even been mentioned on the list by git devs).

b. Avoiding the commits was already not deterministic due
to (2) above. So the caller might have seen full
headers for these commits anyway, and would need to be
prepared for it.

Many places in "git apply" knew that "/dev/null" that signals
"there is no such file on this side of the diff" can be followed by
whitespace and garbage when parsing a patch, except for one, which
made an otherwise valid patch (e.g. ones from subversion) rejected.

config: change default of `pager.config` to "on"Martin Ågren Wed, 21 Feb 2018 18:51:44 +0000 (19:51 +0100)

config: change default of `pager.config` 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.config`
at all when we are not listing or getting configuration. This change
will help with listing large configurations, but will not hurt users of
`git config --edit` as it would have before the previous commit.

config: respect `pager.config` in list/get-mode onlyMartin Ågren Wed, 21 Feb 2018 18:51:43 +0000 (19:51 +0100)

config: respect `pager.config` in list/get-mode only

Similar to de121ffe5 (tag: respect `pager.tag` in list-mode only,
2017-08-02), use the DELAY_PAGER_CONFIG-mechanism to only respect
`pager.config` when we are listing or "get"ing config.

We have several getters and some are guaranteed to give at most one line
of output. Paging all getters including those could be convenient from a
documentation point-of-view. The downside would be that a misconfigured
or not so modern pager might wait for user interaction before
terminating. Let's instead respect the config for precisely those
getters which may produce more than one line of output.

`--get-urlmatch` may or may not produce multiple lines of output,
depending on the exact usage. Let's not try to recognize the two modes,
but instead make `--get-urlmatch` always respect the config. Analyzing
the detailed usage might be trivial enough here, but could establish a
precedent that we will never be able to enforce throughout the codebase
and that will just open a can of worms.

This fixes the failing test added in the previous commit. Also adapt the
test for whether `git config foo.bar bar` and `git config --get foo.bar`
respects `pager.config`.

t7006: add tests for how git config paginatesMartin Ågren Wed, 21 Feb 2018 18:51:42 +0000 (19:51 +0100)

t7006: add tests for how git config paginates

The next couple of commits will change how `git config` handles
`pager.config`, 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`. Similar work has
also been done to `git branch`.

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
tests for simple config-setting, `--edit`, `--get`, `--get-urlmatch`,
`get-all`, and `--list`. Those represent a fair portion of the various
options that will be affected by the next two commits.

Use `test_expect_failure` to document that we currently respect the
pager-configuration with `--edit`. 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).

The next commit will teach simple config-setting and `--get` to ignore
`pager.config`. Test the current behavior as "success", not "failure",
since the currently expected behavior according to documentation would
be to page. The next commit will change that expectation by updating the
documentation on `git config` and will redefine those successful tests.

Remove the test added in commit 3ba7e6e29a (config: run
setup_git_directory_gently() sooner, 2010-08-05) since it has some
overlap with these. We could leave it or tweak it, or place new tests
like these next to it, but let's instead make the tests for `git config`
as similar as possible to the ones for `git tag` and `git branch`, and
place them after those.
