Newer version of GPGSM changed its output in a backward
incompatible way to break our code that parses its output. It also
added more processes our tests need to kill when cleaning up.
Adjustments have been made to accommodate these changes.
* fs/gpgsm-update:
t/lib-gpg: kill all gpg components, not just gpg-agent
t/lib-gpg: reload gpg components after updating trustlist
gpg-interface/gpgsm: fix for v2.3
Checking if signing was successful will now accept '[GNUPG]:
SIG_CREATED' on the beginning of the first or any subsequent line. Not
just explictly the second one anymore.
Gpgsm v2.3 changed its output when listing keys from `fingerprint` to
`sha1/2 fpr`. This leads to the gpgsm tests silently not being executed
because of a failed prerequisite.
Switch to gpg's `--with-colons` output format when evaluating test
prerequisites to make parsing more robust. This also allows us to
combine the existing grep/cut/tr/echo pipe for writing the trustlist.txt
into a single awk expression.
Adjust error message checking in test for v2.3 specific output changes.

"git name-rev --stdin" does not behave like usual "--stdin" at
all. Start the process of renaming it to "--annotate-stdin".
* jc/name-rev-stdin:
name-rev.c: use strbuf_getline instead of limited size buffer
name-rev: deprecate --stdin in favor of --annotate-stdin
The `--diff-filter=<bits>` option allows to filter the diff by certain
criteria, for example `R` to only show renamed files. It also supports
negating a filter via a down-cased letter, i.e. `r` to show _everything
but_ renamed files.
However, the code is a bit overzealous when trying to figure out whether
`git diff` should start with all diff-filters turned on because the user
provided a lower-case letter: if the `--diff-filter` argument starts
with an upper-case letter, we must not start with all bits turned on.
Even worse, it is possible to specify the diff filters in multiple,
separate options, e.g. `--diff-filter=AM [...] --diff-filter=m`.
Let's accumulate the include/exclude filters independently, and only
special-case the "only exclude filters were specified" case after
parsing the options altogether.
Note: The code replaced by this commit took pains to avoid setting any
unused bits of `options->filter`. That was unnecessary, though, as all
accesses happen via the `filter_bit_tst()` function using specific bits,
and setting the unused bits has no effect. Therefore, we can simplify
the code by using `~0` (or in this instance, `~<unwanted-bit>`).

The option --invert-grep is documented to filter out commits whose
messages match the --grep filters. However, it also affects the
header matches (--author, --committer), which is not intended.
Move the handling of that option to grep.c, as only the code there can
distinguish between matches in the header from those in the message
body. If --invert-grep is given then enable extended expressions (not
the regex type, we just need git grep's --not to work), negate the body
patterns and check if any of them match by piggy-backing on the
collect_hits mechanism of grep_source_1().
Collecting the matches in struct grep_opt is a bit iffy, but with
"last_shown" we have a precedent for writing state information to that
struct.

Several tests assign the output of `$(...)` command substitution to an
"expect" variable, taking advantage of the fact that `$(...)` folds out
the final line terminator while leaving internal line terminators
intact. They do this because the "actual" string with which "expect"
will be compared is shaped the same way. However, this intent (having
internal line terminators, but no final line terminator) is not
necessarily obvious at first glance and may confuse casual readers. The
intent can be made more obvious by using `printf` instead, with which
line termination is stated clearly:
printf "sixth\nthird"
In fact, many other tests in this script already use `printf` for
precisely this purpose, thus it is an established pattern. Therefore,
convert these tests to employ `printf`, as well.
While at it, modernize the tests to use test_cmp() to compare the
expected and actual output rather than using the semi-deprecated
`verbose test "$x" = "$y"`.

It's possible to specify --simplify-by-decoration but not --decorate. In
this case we do respect the simplification, but we don't actually show
any decorations. However, it works by lazy-loading the decorations when
needed; this is discussed in more detail in 0cc7380d88 (log-tree: call
load_ref_decorations() in get_name_decoration(), 2019-09-08).
This works for basic cases, but will fail to respect any --decorate-refs
option (or its variants). Those are handled only when cmd_log_init()
loads the ref decorations up front, which is only when --decorate is
specified explicitly (or as of the previous commit, when the userformat
asks for %d or similar).
We can solve this by making sure to load the decorations if we're going
to simplify using them but they're not otherwise going to be displayed.
The new test shows a simple case that fails without this patch. Note
that we expect two commits in the output: the one we asked for by
--decorate-refs, and the initial commit. The latter is just a quirk of
how --simplify-by-decoration works. Arguably it may be a bug, but it's
unrelated to this patch (which is just about the loading of the
decorations; you get the same behavior before this patch with an
explicit --decorate).

In order to show ref decorations, we first have to load them. If you
run:
git log --decorate
then git-log will recognize the option and load them up front via
cmd_log_init(). Likewise if log.decorate is set.
If you don't say --decorate explicitly, but do mention "%d" or "%D" in
the output format, like so:
git log --format=%d
then this also works, because we lazy-load the ref decorations. This has
been true since 3b3d443feb (add '%d' pretty format specifier to show
decoration, 2008-09-04), though the lazy-load was later moved into
log-tree.c.
But there's one problem: that lazy-load just uses the defaults; it
doesn't take into account any --decorate-refs options (or its exclude
variant, or their config). So this does not work:
git log --decorate-refs=whatever --format=%d
It will decorate using all refs, not just the specified ones. This has
been true since --decorate-refs was added in 65516f586b (log: add option
to choose which refs to decorate, 2017-11-21). Adding further confusion
is that it _may_ work because of the auto-decoration feature. If that's
in use (and it often is, as it's the default), then if the output is
going to stdout, we do enable decorations early (and so load them up
front, respecting the extra options). But otherwise we do not. So:
git log --decorate-refs=whatever --format=%d >some-file
would typically behave differently than it does when the output goes to
the pager or terminal!
The solution is simple: we should recognize in cmd_log_init() that we're
going to show decorations, and make sure we load them there. We already
check userformat_find_requirements(), so we can couple this with our
existing code there.
There are two new tests. The first shows off the actual fix. The second
makes sure that our fix doesn't cause us to stomp on an existing
--decorate option (see the new comment in the code, as well).

making them harder to spot.
Teach the pretty-printer code to highlight matches from the

options (to view the last one, you may have to ask for --pretty=fuller).
Also, it must be noted that we are effectively greping the content twice
(because it would be a hassle to rework the existing matching code to do
a /g match and then pass it all down to the coloring code), however it only
slows down "git log --author=^H" on this repository by around 1-2%

pretty.h: update and expand docstring for userformat_find_requirements()
Commit 88473c8bae ("load_ref_decorations(): avoid parsing non-tag
objects", 2021-06-22) introduced a shortcut to `add_ref_decoration()`:
Rather than calling `parse_object()`, we go for `oid_object_info()` and
then `lookup_object_by_type()` using the type just discovered. As
detailed in the commit message, this provides a significant time saving.
Unfortunately, it also changes the behavior: We lose all annotated tags
from the decoration.
The reason this happens is in the loop where we try to peel the tags, we
won't necessarily have parsed that first object. If we haven't, its
`tagged` field will be NULL, so we won't actually add a decoration for
the pointed-to object.
Make sure to parse the tag object at the top of the peeling loop. This
effectively restores the pre-88473c8bae parsing -- but only of tags,
allowing us to keep most of the possible speedup from 88473c8bae.
On my big ~220k ref test case (where it's mostly non-tags), the
timings [using "git log -1 --decorate"] are:
- before either patch: 2.945s
- with my broken patch: 0.707s
- with [this patch]: 0.788s
The simplest way to do this is to just conditionally parse before the
loop:
if (obj->type == OBJ_TAG)
parse_object(&obj->oid);
But we can observe that our tag-peeling loop needs to peel already, to
examine recursive tags-of-tags. So instead of introducing a new call to
parse_object(), we can simply move the parsing higher in the loop:
instead of parsing the new object before we loop, parse each tag object
before we look at its "tagged" field.
This has another beneficial side effect: if a tag points at a commit (or
other non-tag type), we do not bother to parse the commit at all now.
And we know it is a commit without calling oid_object_info(), because
parsing the surrounding tag object will have created the correct in-core
object based on the "type" field of the tag.
Our test coverage for --decorate was obviously not good, since we missed
this quite-basic regression. The new tests covers an annotated tag
(showing the fix), but also that we correctly show annotations for
lightweight tags and double-annotated tag-of-tags.

In addition to the manual adjustment to let the `linux-gcc` CI job run
the test suite with `master` and then with `main`, this patch makes sure
that GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME is set in all test scripts
that currently rely on the initial branch name being `master by default.
To determine which test scripts to mark up, the first step was to
force-set the default branch name to `master` in
- all test scripts that contain the keyword `master`,
- t4211, which expects `t/t4211/history.export` with a hard-coded ref to
initialize the default branch,
- t5560 because it sources `t/t556x_common` which uses `master`,
- t8002 and t8012 because both source `t/annotate-tests.sh` which also
uses `master`)
This trick was performed by this command:
$ sed -i '/^ *\. \.\/\(test-lib\|lib-\(bash\|cvs\|git-svn\)\|gitweb-lib\)\.sh$/i\
GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master\
export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME\
' $(git grep -l master t/t[0-9]*.sh) \
t/t4211*.sh t/t5560*.sh t/t8002*.sh t/t8012*.sh
After that, careful, manual inspection revealed that some of the test
scripts containing the needle `master` do not actually rely on a
specific default branch name: either they mention `master` only in a
comment, or they initialize that branch specificially, or they do not
actually refer to the current default branch. Therefore, the
aforementioned modification was undone in those test scripts thusly:
$ git checkout HEAD -- \

We excluded one set of test scripts in these commands, though: the range
of `git p4` tests. The reason? `git p4` stores the (foreign) remote
branch in the branch called `p4/master`, which is obviously not the
default branch. Manual analysis revealed that only five of these tests
actually require a specific default branch name to pass; They were
modified thusly:

* jk/rev-input-given-fix:
revision: set rev_input_given in handle_revision_arg()
Commit 7ba826290a (revision: add rev_input_given flag, 2017-08-02) added
a flag to rev_info to tell whether we got any revision arguments. As
explained there, this is necessary because some revision arguments may
not produce any pending traversal objects, but should still inhibit
default behaviors (e.g., a glob that matches nothing).
However, it only set the flag in the globbing code, but not for
revisions we get on the command-line or via stdin. This leads to two
problems:
- the command-line code keeps its own separate got_rev_arg flag; this
isn't wrong, but it's confusing and an extra maintenance burden
- even specifically-named rev arguments might end up not adding any
pending objects: if --ignore-missing is set, then specifying a
missing object is a noop rather than an error.
And that leads to some user-visible bugs:
- when deciding whether a default rev like "HEAD" should kick in, we
check both got_rev_arg and rev_input_given. That means that
"--ignore-missing $ZERO_OID" works on the command-line (where we set
got_rev_arg) but not on --stdin (where we don't)
- when rev-list decides whether it should complain that it wasn't
given a starting point, it relies on rev_input_given. So it can't
even get the command-line "--ignore-missing $ZERO_OID" right
Let's consistently set the flag if we got any revision argument. That
lets us clean up the redundant got_rev_arg, and fixes both of those bugs
(but note there are three new tests: we'll confirm the already working
git-log command-line case).
A few implementation notes:
- conceptually we want to set the flag whenever handle_revision_arg()
finds an actual revision arg ("handles" it, you might say). But it
covers a ton of cases with early returns. Rather than annotating
each one, we just wrap it and use its success exit-code to set the
flag in one spot.
- the new rev-list test is in t6018, which is titled to cover globs.
This isn't exactly a glob, but it made sense to stick it with the
other tests that handle the "even though we got a rev, we have no
pending objects" case, which are globs.
- the tests check for the oid of a missing object, which it's pretty
clear --ignore-missing should ignore. You can see the same behavior
with "--ignore-missing a-ref-that-does-not-exist", because
--ignore-missing treats them both the same. That's perhaps less
clearly correct, and we may want to change that in the future. But
the way the code and tests here are written, we'd continue to do the
right thing even if it does.

This reverts commit 489947cee5, which
stopped treating merges into the 'master' branch as special when
preparing the default merge message. As the goal was not to have
any single branch designated as special, it solved it by leaving the
"into <branchname>" at the end of the title of the default merge
message for any and all branches. An obvious and easy alternative
to treat everybody equally could have been to remove it for every
branch, but that involves loss of information.
We'll introduce a new mechanism to let end-users specify merges into
which branches would omit the "into <branchname>" from the title of
the default merge message, and make the mechanism, when unconfigured,
treat the traditional 'master' special again, so all the changes to

In the context of many projects renaming their primary branch names away
from `master`, Git wants to stop treating the `master` branch specially.
Let's start with `git fmt-merge-msg`.

f1e3df3169 (t: increase test coverage of signature verification output,
2020-03-04) adds GPG dependent tests to t4202 and t6200 that were found
problematic with at least OpenBSD 6.7.
Using an escaped '|' for alternations works only in some implementations
of grep (e.g. GNU and busybox).
It is not part of POSIX[1] and not supported by some BSD, macOS, and
possibly other POSIX compatible implementations.
Use `grep -E`, and write it using extended regular expression.

In 'git log', the --decorate-refs-exclude option appends a pattern
to a string_list. This list is used to prevent showing some refs
in the decoration output, or even by --simplify-by-decoration.
Users may want to use their refs space to store utility refs that
should not appear in the decoration output. For example, Scalar [1]
runs a background fetch but places the "new" refs inside the
refs/scalar/hidden/<remote>/* refspace instead of refs/<remote>/*
to avoid updating remote refs when the user is not looking. However,
these "hidden" refs appear during regular 'git log' queries.
A similar idea to use "hidden" refs is under consideration for core
Git [2].
Add the 'log.excludeDecoration' config option so users can exclude
some refs from decorations by default instead of needing to use
--decorate-refs-exclude manually. The config value is multi-valued
much like the command-line option. The documentation is careful to
point out that the config value can be overridden by the
--decorate-refs option, even though --decorate-refs-exclude would
always "win" over --decorate-refs.
Since the 'log.excludeDecoration' takes lower precedence to
--decorate-refs, and --decorate-refs-exclude takes higher
precedence, the struct decoration_filter needed another field.
This led also to new logic in load_ref_decorations() and
ref_filter_match().
There are several tests in t4202-log.sh that test the
--decorate-refs-(include|exclude) options, so these are extended.
Since the expected output is already stored as a file, most tests
could simply replace a "--decorate-refs-exclude" option with an
in-line config setting. Other tests involve the precedence of
the config option compared to command-line options and needed more
modification.

The code to interface with GnuPG has been refactored.
* hi/gpg-prefer-check-signature:
gpg-interface: prefer check_signature() for GPG verification
t: increase test coverage of signature verification output
There weren't any tests for unsuccessful signature verification of
signed merge tags shown in 'git log'. There also weren't any tests for
the GPG output from 'git fmt-merge-msg'. This was noticed while
investigating a buggy refactor that slipped through the test suite; see
commit 72b006f4bf.
This commit adds signature verification tests to the 'log' and
'fmt-merge-msg' builtins.
Thanks to Linus Torvalds for reporting and finding the (now reverted)
commit that introduced the regression.
Note that the "log --show-signature for merged tag with GPG failure"
test case is really hacky. It relies on an implementation detail of
verify_signed_buffer() -- namely, it assumes that the signature is
written to a temporary file whose path is under TMPDIR.
The rationale for that test case is to check whether the code path that
yields the "No signature" message is reachable on failure. The
functionality in log-tree.c that may show this message does some
pre-parsing of a possible signature that prevents the GPG interface from
being invoked if a signature is actually missing. And I haven't been
able to construct a signature that both 1. satisfies that
pre-processing, and 2. causes GPG to fail without any sort of output on
stderr along the lines of "this is a bogus/corrupt/... signature" (the
"No signature" message should only be shown if GPG produce no output).

Log graph comparision logic is duplicated many times in:
- t3430-rebase-merges.sh
- t4202-log.sh
- t4214-log-graph-octopus.sh
- t4215-log-skewed-merges.sh
Consolidate the core of the comparision and sanitization logic in
lib-log-graph, and use it to replace the existing tests.
While at it, lose the singular/plural transition magic from the
sanitize_output helper, which was necessary around 7f814632 ("Use
correct grammar in diffstat summary line", 2012-02-01), that has
long outlived its usefulness.

Adjust the test so that it computes values for object IDs instead of
using hard-coded hashes. Additionally, update the sanitize_output
function to sanitize the index lines in diff output, since it's clear
from the assertions in question that we are not interested in the
specific object IDs.

The code to parse GPG output used to assume incorrectly that the
finterprint for the primary key would always be present for a valid
signature, which has been corrected.
* hi/gpg-optional-pkfp-fix:
gpg-interface: limit search for primary key fingerprint
gpg-interface: refactor the free-and-xmemdupz pattern
The VALIDSIG status line from GnuPG with --status-fd is documented to
have 9 required and 1 optional fields [1]. The final, and optional,
field is used to specify the fingerprint of the primary key that made
the signature in case it was made by a subkey. However, this field is
only available for OpenPGP signatures; not for CMS/X.509.
If the VALIDSIG status line does not have the optional 10th field, the
current code will continue reading onto the next status line. And this
is the case for non-OpenPGP signatures [1].
The consequence is that a subsequent status line may be considered as
the "primary key" for signatures that does not have an actual primary
key.
Limit the search of these 9 or 10 fields to the single line to avoid
this problem. If the 10th field is missing, report that there is no
primary key fingerprint.

When a graph contains edges that are in the process of collapsing to the
left, but those edges cross a commit line, the effect is that the edges
have a jagged appearance:
*
|\
| *
| \
*-. \
|\ \ \
| | * |
| * | |
| |/ /
* | |
|/ /
* |
|/
*
We already takes steps to smooth edges like this when they're expanding;
when an edge appears to the right of a merge commit marker on a
GRAPH_COMMIT line immediately following a GRAPH_POST_MERGE line, we
render it as a `\`:
* \
|\ \
| * \
| |\ \
We can make a similar improvement to collapsing edges, making them
easier to follow and giving the overall graph a feeling of increased
symmetry:
*
|\
| *
| \
*-. \
|\ \ \
| | * |
| * | |
| |/ /
* / /
|/ /
* /
|/
*
To do this, we introduce a new special case for edges on GRAPH_COMMIT
lines that immediately follow a GRAPH_COLLAPSING line. By retaining a
copy of the `mapping` array used to render the GRAPH_COLLAPSING line in
the `old_mapping` array, we can determine that an edge is collapsing
through the GRAPH_COMMIT line and should be smoothed.
