2019-12-05Merge branch 'hi/gpg-optional-pkfp-fix'Libravatar Junio C Hamano1-0/+20
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
2019-11-23gpg-interface: limit search for primary key fingerprintLibravatar Hans Jerry Illikainen1-0/+20
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.

2019-10-16graph: smooth appearance of collapsing edges on commit linesLibravatar James Coglan1-1/+1
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.

Load a default set of ref name decorations at the first lookup. This frees direct and indirect callers from doing so. They can still do it if they want to use a filter or are interested in full decorations instead of the default short ones -- the first load_ref_decorations() call wins. This means that the load in builtin/log.c::cmd_log_init_finish() is respected even if --simplify-by-decoration is given, as the previously dominating earlier load in handle_revision_opt() is gone.

2019-08-06parse-options: allow --end-of-options as a synonym for "--"Libravatar Jeff King1-0/+7
The revision option parser recently learned about --end-of-options, but that's not quite enough for all callers. Some of them, like git-log, pick out some options using parse_options(), and then feed the remainder to setup_revisions(). For those cases we need to stop parse_options() from finding more options when it sees --end-of-options, and to retain that option in argv so that setup_revisions() can see it as well. Let's handle this the same as we do "--". We can even piggy-back on the handling of PARSE_OPT_KEEP_DASHDASH, because any caller that wants to retain one will want to retain the other. I've included two tests here. The "log" test covers "--source", which is one of the options it handles with parse_options(), and would fail before this patch. There's also a test that uses the parse-options helper directly. That confirms that the option is handled correctly even in cases without KEEP_DASHDASH or setup_revisions(). I.e., it is safe to use --end-of-options in place of "--" in other programs. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2019-05-14tests: add a special setup where prerequisites failLibravatar Ævar Arnfjörð Bjarmason1-1/+1
As discussed in [1] there's a regression in the "pu" branch now because a new test implicitly assumed that a previous test guarded by a prerequisite had been run. Add a "GIT_TEST_FAIL_PREREQS" special test setup where we'll skip (nearly) all tests guarded by prerequisites, allowing us to easily emulate those platform where we don't run these tests. As noted in the documentation I'm adding I'm whitelisting the SYMLINKS prerequisite for now. A lot of tests started failing if we lied about not supporting symlinks. It's also unlikely that we'll have a failing test due to a hard dependency on symlinks without that being the obvious cause, so for now it's not worth the effort to make it work. 1. https://public-inbox.org/git/nycvar.QRO.7.76.6.1905131531000.44@tvgsbejvaqbjf.bet/ Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Operations on promisor objects make sense in the context of only a small subset of the commands that internally use the revisions machinery, but the "--exclude-promisor-objects" option were taken and led to nonsense results by commands like "log", to which it didn't make much sense. This has been corrected. * md/exclude-promisor-objects-fix: exclude-promisor-objects: declare when option is allowed Documentation/git-log.txt: do not show --exclude-promisor-objects
2018-10-23exclude-promisor-objects: declare when option is allowedLibravatar Matthew DeVore1-0/+4
The --exclude-promisor-objects option causes some funny behavior in at least two commands: log and blame. It causes a BUG crash: $ git log --exclude-promisor-objects BUG: revision.c:2143: exclude_promisor_objects can only be used when fetch_if_missing is 0 Aborted [134] Fix this such that the option is treated like any other unknown option. The commands that must support it are limited, so declare in those commands that the flag is supported. In particular: pack-objects prune rev-list The commands were found by searching for logic which parses --exclude-promisor-objects outside of revision.c. Extra logic outside of revision.c is needed because fetch_if_missing must be turned on before revision.c sees the option or it will BUG-crash. The above list is supported by the fact that no other command is introspectively invoked by another command passing --exclude-promisor-object.

2017-11-22log: add option to choose which refs to decorateLibravatar Rafael Ascensão1-0/+101
When `log --decorate` is used, git will decorate commits with all available refs. While in most cases this may give the desired effect, under some conditions it can lead to excessively verbose output. Introduce two command line options, `--decorate-refs=<pattern>` and `--decorate-refs-exclude=<pattern>` to allow the user to select which refs are used in decoration. When "--decorate-refs=<pattern>" is given, only the refs that match the pattern are used in decoration. The refs that match the pattern when "--decorate-refs-exclude=<pattern>" is given, are never used in decoration. These options follow the same convention for mixing negative and positive patterns across the system, assuming that the inclusive default is to match all refs available. (1) if there is no positive pattern given, pretend as if an inclusive default positive pattern was given; (2) for each candidate, reject it if it matches no positive pattern, or if it matches any one of the negative patterns. The rules for what is considered a match are slightly different from the rules used elsewhere. Commands like `log --glob` assume a trailing '/*' when glob chars are not present in the pattern. This makes it difficult to specify a single ref. On the other hand, commands like `describe --match --all` allow specifying exact refs, but do not have the convenience of allowing "shorthand refs" like 'refs/heads' or 'heads' to refer to 'refs/heads/*'. The commands introduced in this patch consider a match if: (a) the pattern contains globs chars, and regular pattern matching returns a match. (b) the pattern does not contain glob chars, and ref '<pattern>' exists, or if ref exists under '<pattern>/' This allows both behaviours (allowing single refs and shorthand refs) yet remaining compatible with existent commands.

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).

2017-05-24handle_revision_arg: reset "dotdot" consistentlyLibravatar Jeff King1-0/+9
When we are parsing a range like "a..b", we write a temporary NUL over the first ".", so that we can access the names "a" and "b" as C strings. But our restoration of the original "." is done at inconsistent times, which can lead to confusing results. For most calls, we restore the "." after we resolve the names, but before we call verify_non_filename(). This means that when we later call add_pending_object(), the name for the left-hand "a" has been re-expanded to "a..b". You can see this with: git log --source a...b where "b" will be correctly marked with "b", but "a" will be marked with "a...b". Likewise with "a..b" (though you need to use --boundary to even see "a" at all in that case). To top off the confusion, when the REVARG_CANNOT_BE_FILENAME flag is set, we skip the non-filename check, and leave the NUL in place. That means we do report the correct name for "a" in the pending array. But some code paths try to show the whole "a...b" name in error messages, and these erroneously show only "a" instead of "a...b". E.g.: $ git cherry-pick HEAD:foo...HEAD:foo error: object d95f3ad14dee633a758d2e331151e950dd13e4ed is a blob, not a commit error: object d95f3ad14dee633a758d2e331151e950dd13e4ed is a blob, not a commit fatal: Invalid symmetric difference expression HEAD:foo (That last message should be "HEAD:foo...HEAD:foo"; I used cherry-pick because it passes the CANNOT_BE_FILENAME flag). As an interesting side note, cherry-pick actually looks at and re-resolves the arguments from the pending->name fields. So it would have been visibly broken by the first bug, but the effect was canceled out by the second one. This patch makes the whole function consistent by re-writing the NUL immediately after calling verify_non_filename(), and then restoring the "." as appropriate in some error-printing and early-return code paths.

Add a test asserting that when --perl-regexp (and -P for grep) is given to git-grep & git-log that we die with an error.

'git grep -P '[\d]' would match "d" instead of digits.

Add exhaustive tests for how the different grep.patternType options & the corresponding command-line options affect git-log. Before this change it was possible to patch revision.c so that the --basic-regexp option was synonymous with --extended-regexp, and --perl-regexp wasn't recognized at all, and still have 100% of the test suite pass. This was because the first test being modified here, added in commit 34a4ae55b2 ("log --grep: use the same helper to set -E/-F options as "git grep"", 2012-10-03), didn't actually check whether we'd enabled extended regular expressions as distinct from re-toggling non-fixed string support. Fix that by changing the pattern to a pattern that'll only match if --extended-regexp option is provided, but won't match under the default --basic-regexp option. Other potential regressions were possible since there were no tests for the rest of the combinations of grep.patternType configuration toggles & corresponding git-log command-line options. Add exhaustive tests for those. The patterns being passed to fixed/basic/extended/PCRE are carefully crafted to return the wrong thing if the grep engine were to pick any other matching method than the one it's told to use.

The recent change that introduced autodecorating of refs accidentally broke the ability of users to set log.decorate = false to override it.

2017-03-29name-rev: favor describing with tags and use committer date to tiebreakLibravatar Junio C Hamano1-1/+1
"git name-rev" assigned a phony "far in the future" date to tips of refs that are not pointing at tag objects, and favored names based on a ref with the oldest date. This made it almost impossible for an unannotated tags and branches to be counted as a viable base, which was especially problematic when the command is run with the "--tags" option. If an unannotated tag that points at an ancient commit and an annotated tag that points at a much newer commit reaches the commit that is being named, the old unannotated tag was ignored. Update the "taggerdate" field of the rev-name structure, which is initialized from the tip of ref, to have the committer date if the object at the tip of ref is a commit, not a tag, so that we can optionally take it into account when doing "is this name better?" comparison logic. When "name-rev" is run without the "--tags" option, the general expectation is still to name the commit based on a tag if possible, but use non-tag refs as fallback, and tiebreak among these non-tag refs by favoring names with shorter hops from the tip. The use of a phony "far in the future" date in the original code was an effective way to ensure this expectation is held: a non-tag tip gets the same "far in the future" timestamp, giving precedence to tags, and among non-tag tips, names with shorter hops are preferred over longer hops, without taking the "taggerdate" into account. As we are taking over the "taggerdate" field to store the committer date for tips with commits: (1) keep the original logic when comparing names based on two refs both of which are from refs/tags/; (2) favoring a name based on a ref in refs/tags/ hierarchy over a ref outside the hierarchy; (3) between two names based on a ref both outside refs/tags/, give precedence to a name with shorter hops and use "taggerdate" only to tie-break. A change to t4202 is a natural consequence. The test creates a commit on a branch "side" and points at it with an unannotated tag "refs/tags/side-2". The original code couldn't decide which one to favor at all, and gave a name based on a branch (simply because refs/heads/side sorts earlier than refs/tags/side-2). Because the updated logic is taught to favor refs in refs/tags/ hierarchy, the the test is updated to expect to see tags/side-2 instead.

"git log --graph" did not work well with "--name-only", even though other forms of "diff" output were handled correctly. * jk/log-graph-name-only: diff: print line prefix for --name-only output
2017-02-08diff: print line prefix for --name-only outputLibravatar Jeff King1-0/+48
If you run "git log --graph --name-only", the pathnames are not indented to go along with their matching commits (unlike all of the other diff formats). We need to output the line prefix for each item before writing it. The tests cover both --name-status and --name-only. The former actually gets this right already, because it builds on the --raw format functions. It's only --name-only which uses its own code (and this fix mirrors the code in diff_flush_raw()). Note that the tests don't follow our usual style of setting up the "expect" output inside the test block. This matches the surrounding style, but more importantly it is easier to read: we don't have to worry about embedded single-quotes, and the leading indentation is more obvious.

Some people feel the default set of colors used by "git log --graph" rather limiting. A mechanism to customize the set of colors has been introduced. * nd/log-graph-configurable-colors: document behavior of empty color name color_parse_mem: allow empty color spec log --graph: customize the graph lines with config log.graphColors color.c: trim leading spaces in color_parse_mem() color.c: fix color_parse_mem() with value_len == 0
2017-01-31color_parse_mem: allow empty color specLibravatar Jeff King1-1/+1
Prior to c2f41bf52 (color.c: fix color_parse_mem() with value_len == 0, 2017-01-19), the empty string was interpreted as a color "reset". This was an accidental outcome, and that commit turned it into an error. However, scripts may pass the empty string as a default value to "git config --get-color" to disable color when the value is not defined. The git-add--interactive script does this. As a result, the script is unusable since c2f41bf52 unless you have color.diff.plain defined (if it is defined, then we don't parse the empty default at all). Our test scripts didn't notice the recent breakage because they run without a terminal, and thus without color. They never hit this code path at all. And nobody noticed the original buggy "reset" behavior, because it was effectively a noop. Let's fix the code to have an empty color name produce an empty sequence of color codes. The tests need a few fixups: - we'll add a new test in t4026 to cover this case. But note that we need to tweak the color() helper. While we're there, let's factor out the literal ANSI ESC character. Otherwise it makes the diff quite hard to read. - we'll add a basic sanity-check in t4026 that "git add -p" works at all when color is enabled. That would have caught this bug, as well as any others that are specific to the color code paths. - 73c727d69 (log --graph: customize the graph lines with config log.graphColors, 2017-01-19) added a test to t4202 that checks some "invalid" graph color config. Since ",, blue" before yielded only "blue" as valid, and now yields "empty, empty, blue", we don't match the expected output. One way to fix this would be to change the expectation to the empty color strings. But that makes the test much less interesting, since we show only two graph lines, both of which would be colorless. Since the empty-string case is now covered by t4026, let's remove them entirely here. They're just in the way of the primary thing the test is supposed to be checking.

2017-01-23log --graph: customize the graph lines with config log.graphColorsLibravatar Nguyễn Thái Ngọc Duy1-0/+22
If you have a 256 colors terminal (or one with true color support), then the predefined 12 colors seem limited. On the other hand, you don't want to draw graph lines with every single color in this mode because the two colors could look extremely similar. This option allows you to hand pick the colors you want. Even with standard terminal, if your background color is neither black or white, then the graph line may match your background and become hidden. You can exclude your background color (or simply the colors you hate) with this. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2016-08-31graph: add support for --line-prefix on all graph-aware outputLibravatar Jacob Keller1-0/+323
Add an extension to git-diff and git-log (and any other graph-aware displayable output) such that "--line-prefix=<string>" will print the additional line-prefix on every line of output. To make this work, we have to fix a few bugs in the graph API that force graph_show_commit_msg to be used only when you have a valid graph. Additionally, we extend the default_diff_output_prefix handler to work even when no graph is enabled. This is somewhat of a hack on top of the graph API, but I think it should be acceptable here. This will be used by a future extension of submodule display which displays the submodule diff as the actual diff between the pre and post commit in the submodule project. Add some tests for both git-log and git-diff to ensure that the prefix is honored correctly. Signed-off-by: Jacob Keller <jacob.keller@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2016-07-25grep: further simplify setting the pattern typeLibravatar Junio C Hamano1-0/+14
When c5c31d33 (grep: move pattern-type bits support to top-level grep.[ch], 2012-10-03) introduced grep_commit_pattern_type() helper function, the intention was to allow the users of grep API to having to fiddle only with .pattern_type_option (which can be set to "fixed", "basic", "extended", and "pcre"), and then immediately before compiling the pattern strings for use, call grep_commit_pattern_type() to have it prepare various bits in the grep_opt structure (like .fixed, .regflags, etc.). However, grep_set_pattern_type_option() helper function the grep API internally uses were left as an external function by mistake. This function shouldn't have been made callable by the users of the API. Later when the grep API was used in revision traversal machinery, the caller then mistakenly started calling the function around 34a4ae55 (log --grep: use the same helper to set -E/-F options as "git grep", 2012-10-03), instead of setting the .pattern_type_option field and letting the grep_commit_pattern_type() to take care of the details. This caused an unnecessary bug that made a configured grep.patternType take precedence over the command line options (e.g. --basic-regexp, --fixed-strings) in "git log" family of commands.

2016-02-25diff: activate diff.renames by defaultLibravatar Matthieu Moy1-4/+4
Rename detection is a very convenient feature, and new users shouldn't have to dig in the documentation to benefit from it. Potential objections to activating rename detection are that it sometimes fail, and it is sometimes slow. But rename detection is already activated by default in several cases like "git status" and "git merge", so activating diff.renames does not fundamentally change the situation. When the rename detection fails, it now fails consistently between "git diff" and "git status". This setting does not affect plumbing commands, hence well-written scripts will not be affected.

History traversal with "git log --source" that starts with an annotated tag failed to report the tag as "source", due to an old regression in the command line parser back in v2.2 days. * jk/pending-keep-tag-name: revision.c: propagate tag names from pending array
2015-12-17revision.c: propagate tag names from pending arrayLibravatar Jeff King1-0/+29
When we unwrap a tag to find its commit for a traversal, we do not propagate the "name" field of the tag in the pending array (i.e., the ref name the user gave us in the first place) to the commit (instead, we use an empty string). This means that "git log --source" will never show the tag-name for commits we reach through it. This was broken in 2073949 (traverse_commit_list: support pending blobs/trees with paths, 2014-10-15). That commit tried to be careful and avoid propagating the path information for a tag (which would be nonsensical) to trees and blobs. But it should not have cut off the "name" field, which should carry forward to children. Note that this does mean that the "name" field will carry forward to blobs and trees, too. Whereas prior to 2073949, we always gave them an empty string. This is the right thing to do, but in practice no callers probably use it (since now we have an explicit separate "path" field, which was the point of 2073949). We add tests here not only for the broken case, but also a basic sanity test of "log --source" in general, which did not have any coverage in the test suite.
