2019-02-21tests: fix unportable "\?" and "\+" regex syntaxLibravatar Ævar Arnfjörð Bjarmason1-4/+4
Fix widely supported but non-POSIX basic regex syntax introduced in [1] and [2]. On GNU, NetBSD and FreeBSD the following works: $ echo xy >f $ grep 'xy\?' f; echo $? xy 0 The same goes for "\+". The "?" and "+" syntax is not in the BRE syntax, just in ERE, but on some implementations it can be invoked by prefixing the meta-operator with "\", but not on OpenBSD: $ uname -a OpenBSD obsd.my.domain 6.2 GENERIC#132 amd64 $ grep --version grep version 0.9 $ grep 'xy\?' f; echo $? 1 Let's fix this by moving to ERE syntax instead, where "?" and "+" are universally supported: $ grep -E 'xy?' f; echo $? xy 0 1. 2ed5c8e174 ("describe: setup working tree for --dirty", 2019-02-03) 2. c801170b0c ("t6120: test for describe with a bare repository", 2019-02-03) Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2019-02-04describe: setup working tree for --dirtyLibravatar Sebastian Staudt1-0/+33
We don't use NEED_WORK_TREE when running the git-describe builtin, since you should be able to describe a commit even in a bare repository. However, the --dirty flag does need a working tree. Since we don't call setup_work_tree(), it uses whatever directory we happen to be in. That's unlikely to match our index, meaning we'd say "dirty" even when the real working tree is clean. We can fix that by calling setup_work_tree() once we know that the user has asked for --dirty. The --broken option also needs a working tree. But because its implementation calls git-diff-index we don‘t have to setup the working tree in the git-describe process.

2018-08-21tests: use 'test_must_be_empty' instead of 'test_cmp <empty> <out>'Libravatar SZEDER Gábor1-2/+1
Using 'test_must_be_empty' is shorter and more idiomatic than >empty && test_cmp empty out as it saves the creation of an empty file. Furthermore, sometimes the expected empty file doesn't have such a descriptive name like 'empty', and its creation is far away from the place where it's finally used for comparison (e.g. in 't7600-merge.sh', where two expected empty files are created in the 'setup' test, but are used only about 500 lines later). These cases were found by instrumenting 'test_cmp' to error out the test script when it's used to compare empty files, and then converted manually. Note that even after this patch there still remain a lot of cases where we use 'test_cmp' to check empty files: - Sometimes the expected output is not hard-coded in the test, but 'test_cmp' is used to ensure that two similar git commands produce the same output, and that output happens to be empty, e.g. the test 'submodule update --merge - ignores --merge for new submodules' in 't7406-submodule-update.sh'. - Repetitive common tasks, including preparing the expected results and running 'test_cmp', are often extracted into a helper function, and some of this helper's callsites expect no output. - For the same reason as above, the whole 'test_expect_success' block is within a helper function, e.g. in 't3070-wildmatch.sh'. - Or 'test_cmp' is invoked in a loop, e.g. the test 'cvs update (-p)' in 't9400-git-cvsserver-server.sh'.

2018-02-12describe: confirm that blobs actually existLibravatar Jeff King1-0/+8
Prior to 644eb60bd0 (builtin/describe.c: describe a blob, 2017-11-15), we noticed and complained about missing objects, since they were not valid commits: $ git describe 0000000000000000000000000000000000000000 fatal: 0000000000000000000000000000000000000000 is not a valid 'commit' object After that commit, we feed any non-commit to lookup_blob(), and complain only if it returns NULL. But the lookup_* functions do not actually look at the on-disk object database at all. They return an entry from the in-memory object hash if present (and if it matches the requested type), and otherwise auto-create a "struct object" of the requested type. A missing object would hit that latter case: we create a bogus blob struct, walk all of history looking for it, and then exit successfully having produced no output. One reason nobody may have noticed this is that some related cases do still work OK: 1. If we ask for a tree by sha1, then the call to lookup_commit_referecne_gently() would have parsed it, and we would have its true type in the in-memory object hash. 2. If we ask for a name that doesn't exist but isn't a 40-hex sha1, then get_oid() would complain before we even look at the objects at all. We can fix this by replacing the lookup_blob() call with a check of the true type via sha1_object_info(). This is not quite as efficient as we could possibly make this check. We know in most cases that the object was already parsed in the earlier commit lookup, so we could call lookup_object(), which does auto-create, and check the resulting struct's type (or NULL). However it's not worth the fragility nor code complexity to save a single object lookup. The new tests cover this case, as well as that of a tree-by-sha1 (which does work as described above, but was not explicitly tested).

When 212945d4a85dfa172ea55ec73b1d830ef2d8582f ("Teach git-describe to verify annotated tag names before output") made Git favor the embedded name of annotated tags, it accidentally changed the output format when the --all flag is given, only printing the tag's name without the prefix.

2017-12-19builtin/describe.c: describe a blobLibravatar Stefan Beller1-0/+34
Sometimes users are given a hash of an object and they want to identify it further (ex.: Use verify-pack to find the largest blobs, but what are these? or [1]) When describing commits, we try to anchor them to tags or refs, as these are conceptually on a higher level than the commit. And if there is no ref or tag that matches exactly, we're out of luck. So we employ a heuristic to make up a name for the commit. These names are ambiguous, there might be different tags or refs to anchor to, and there might be different path in the DAG to travel to arrive at the commit precisely. When describing a blob, we want to describe the blob from a higher layer as well, which is a tuple of (commit, deep/path) as the tree objects involved are rather uninteresting. The same blob can be referenced by multiple commits, so how we decide which commit to use? This patch implements a rather naive approach on this: As there are no back pointers from blobs to commits in which the blob occurs, we'll start walking from any tips available, listing the blobs in-order of the commit and once we found the blob, we'll take the first commit that listed the blob. For example git describe --tags v0.99:Makefile conversion-901-g7672db20c2:Makefile tells us the Makefile as it was in v0.99 was introduced in commit 7672db20. The walking is performed in reverse order to show the introduction of a blob rather than its last occurrence.

To keep this property of only erroring out, when not in a repository, severe (submodule) errors must be downgraded to reporting them gently instead of having git-describe error out completely.

2015-08-25describe --contains: default to HEAD when no commit-ish is givenLibravatar SZEDER Gábor1-0/+8
'git describe --contains' doesn't default to HEAD when no commit is given, and it doesn't produce any output, not even an error: ~/src/git ((v2.5.0))$ ./git describe --contains ~/src/git ((v2.5.0))$ ./git describe --contains HEAD v2.5.0^0 Unlike other 'git describe' options, the '--contains' code path is implemented by calling 'name-rev' with a bunch of options plus all the commit-ishes that were passed to 'git describe'. If no commit-ish was present, then 'name-rev' got invoked with none, which then leads to the behavior illustrated above. Porcelain commands usually default to HEAD when no commit-ish is given, and 'git describe' already does so in all other cases, so it should do so with '--contains' as well. Pass HEAD to 'name-rev' when no commit-ish is given on the command line to make '--contains' behave consistently with other 'git describe' options. While at it, use argv_array_pushv() instead of the loop to pass commit-ishes to 'git name-rev'. 'git describe's short help already indicates that the commit-ish is optional, but the synopsis in the man page doesn't, so update it accordingly as well.

2013-07-18describe: fix --contains when a tag is given as inputLibravatar Junio C Hamano1-0/+12
"git describe" takes a commit and gives it a name based on tags in its neighbourhood. The command does take a commit-ish but when given a tag that points at a commit, it should dereference the tag before computing the name for the commit. As the whole processing is internally delegated to name-rev, if we unwrap tags down to the underlying commit when invoking name-rev, it will make the name-rev issue an error message based on the unwrapped object name (i.e. either 40-hex object name, or "$tag^0") that is different from what the end-user gave to the command when the commit cannot be described.

If more than one annotated tag points at the same commit, use the tag whose tagger field has a more recent date stamp. This resolves non-deterministic cases where the maintainer has done: $ git tag -a -m "2.1-rc1" v2.1-rc1 deadbeef $ git tag -a -m "2.1" v2.1 deadbeef If the tag is an older-style annotated tag with no tagger date, we assume a date stamp at the UNIX epoch. This will cause us to prefer an annotated tag that has a valid date. We could also try to consider the tag object chain, favoring a tag that "includes" another one: $ git tag -a -m "2.1-rc0" v2.1-rc1 deadbeef $ git tag -a -m "2.1" v2.1 v2.1-rc1 However traversing the tag's object chain looking for inclusion is much more complicated. Its already very likely that even in these cases the v2.1 tag will have a more recent tagger date than v2.1-rc1, so with this change describe should still resolve this by selecting the more recent v2.1.

2009-10-27Teach "git describe" --dirty optionLibravatar Jean Privat1-0/+14
With the --dirty option, git describe works on HEAD but append s"-dirty" iff the contents of the work tree differs from HEAD. E.g. $ git describe --dirty v1.6.5-15-gc274db7 $ echo >> Makefile $ git describe --dirty v1.6.5-15-gc274db7-dirty The --dirty option can also be used to specify what is appended, instead of the default string "-dirty". $ git describe --dirty=.mod v1.6.5-15-gc274db7.mod Many build scripts use `git describe` to produce a version number based on the description of HEAD (on which the work tree is based) + saying that if the build contains uncommitted changes. This patch helps the writing of such scripts since `git describe --dirty` does directly the intended thing. Three possiblities were considered while discussing this new feature: 1. Describe the work tree by default and describe HEAD only if "HEAD" is explicitly specified Pro: does the right thing by default (both for users and for scripts) Pro: other git commands that works on the work tree by default Con: breaks existing scripts used by the Linux kernel and other projects 2. Use --worktree instead of --dirty Pro: does what it says: "git describe --worktree" describes the work tree Con: other commands do not require a --worktree option when working on the work tree (it often is the default mode for them) Con: unusable with an optional value: "git describe --worktree=.mod" is quite unintuitive. 3. Use --dirty as in this patch Pro: makes sense to specify an optional value (what the dirty mark is) Pro: does not have any of the big cons of previous alternatives * does not break scripts * is not inconsistent with other git commands This patch takes the third approach.

2008-03-03Add git-describe test for "verify annotated tag names on output"Libravatar Shawn O. Pearce1-1/+16
Back in 212945d4 ("Teach git-describe to verify annotated tag names before output") I taught git-describe to output the name shown in the "tag" header of an annotated tag, rather than the name it is actually stored under in this repository's ref namespace. This test case verifies this is working correctly by renaming the ref for an annotated tag to a different name that what is recorded in the tag body, and verifying that tag is returned. We also verify there is a message shown on stderr to inform the user that the tag is possibly stored under the wrong name locally. Signed-off-by: Shawn O.

2008-03-03Test for packed tags in git-describe outputLibravatar Shawn O. Pearce1-0/+3
In c374b91c ("git-describe: use tags found in packed-refs correctly") Junio fixed an issue where git-describe did not parse a tag object it obtained from a packed-refs file, as the peel information was read in from packed-refs and not the tag object itself. This new test case verifies the fix listed above is functioning, and does not have a regression in the future. Signed-off-by: Shawn O.

2008-03-03Don't allow git-describe failures to go unnoticed in t6120Libravatar Shawn O. Pearce1-1/+3
If git-describe fails we never execute the test_expect_success, so we never actually test for failure. This is horribly wrong. We need to always run the test case, but the test case is only supposed to succeed if the prior git-describe returned 0. Signed-off-by: Shawn O.

2008-02-25git-describe: --long shows the object name even for a tagged commitLibravatar Santi Béjar1-0/+2
This is useful when you want to see parts of the commit object name in "describe" output, even when the commit in question happens to be a tagged version. Instead of just emitting the tag name, it will describe such a commit as v1.2-0-deadbeef (0th commit since tag v1.2 that points at object deadbeef....).

2007-07-02Rewrite "git-frotz" to "git frotz"Libravatar Junio C Hamano1-11/+11
This uses the remove-dashes target to replace "git-frotz" to "git frotz". Signed-off-by: Junio C Hamano <gitster@pobox.com>
