2020-11-19t[01]*: adjust the references to the default branch name "main"Libravatar Johannes Schindelin1-16/+16
Carefully excluding t1309, which sees independent development elsewhere at the time of writing, we transition above-mentioned tests to the default branch name `main`. This trick was performed via $ (cd t && sed -i -e 's/master/main/g' -e 's/MASTER/MAIN/g' \ -e 's/Master/Main/g' -e 's/naster/nain/g' -- t[01]*.sh && git checkout HEAD -- t1309\*) Note that t5533 contains a variation of the name `master` (`naster`) that we rename here, too. This allows us to define `GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=main` for those tests.

2017-10-18check-ref-format --branch: do not expand @{...} outside repositoryLibravatar Junio C Hamano1-0/+16
Running "git check-ref-format --branch @{-1}" from outside any repository produces $ git check-ref-format --branch @{-1} BUG: environment.c:182: git environment hasn't been setup This is because the expansion of @{-1} must come from the HEAD reflog, which involves opening the repository. @{u} and @{push} (which are more unusual because they typically would not expand to a local branch) trigger the same assertion. This has been broken since day one. Before v2.13.0-rc0~48^2 (setup_git_env: avoid blind fall-back to ".git", 2016-10-02), the breakage was more subtle: Git would read reflogs from ".git" within the current directory even if it was not a valid repository. Usually that is harmless because Git is not being run from the root directory of an invalid repository, but in edge cases such accesses can be confusing or harmful. Since v2.13.0, the problem is easier to diagnose because Git aborts with a BUG message. Erroring out is the right behavior: when asked to interpret a branch name like "@{-1}", there is no reasonable answer in this context. But we should print a message saying so instead of an assertion failure. We do not forbid "check-ref-format --branch" from outside a repository altogether because it is ok for a script to pre-process branch arguments without @{...} in such a context. For example, with pre-2.13 Git, a script that does branch='master'; # default value parse_options branch=$(git check-ref-format --branch "$branch") to normalize an optional branch name provided by the user would work both inside a repository (where the user could provide '@{-1}') and outside (where '@{-1}' should not be accepted). So disable the "expand @{...}" half of the feature when run outside a repository, but keep the check of the syntax of a proposed branch name. This way, when run from outside a repository, "git check-ref-format --branch @{-1}" will gracefully fail: $ git check-ref-format --branch @{-1} fatal: '@{-1}' is not a valid branch name and "git check-ref-format --branch master" will succeed as before: $ git check-ref-format --branch master master restoring the usual pre-2.13 behavior.

2015-07-27refs: loosen restriction on wildcard "*" refspecsLibravatar Jacob Keller1-3/+5
Loosen restrictions on refspecs by allowing patterns that have a "*" within a component instead of only as the whole component. Remove the logic to accept a single "*" as a whole component from check_refname_format(), and implement an extended form of that logic in check_refname_component(). Pass the pointer to the flags argument to the latter, as it has to clear REFNAME_REFSPEC_PATTERN bit when it sees "*". Teach check_refname_component() function to allow an asterisk "*" only when REFNAME_REFSPEC_PATTERN is set in the flags, and drop the bit after seeing a "*", to ensure that one side of a refspec contains at most one asterisk. This will allow us to accept refspecs such as `for/bar*:foo/baz*`. Any refspec which functioned before shall continue functioning with the new logic.

Support for Back when bdccd3c1 (test-lib: allow negation of prerequisites, 2012-11-14) introduced negated predicates (e.g. "!MINGW,!CYGWIN"), we already had 5 test files that use NOT_MINGW (and a few MINGW) as prerequisites.

2014-06-18refs.c: SSE2 optimizations for check_refname_componentLibravatar David Turner1-0/+15
Optimize check_refname_component using SSE2 on x86_64. git rev-parse HEAD is a good test-case for this, since it does almost nothing except parse refs. For one particular repo with about 60k refs, almost all packed, the timings are: Look up table: 29 ms SSE2: 23 ms This cuts about 20% off of the runtime. Ondřej Bílka <neleai@seznam.cz> suggested an SSE2 approach to the substring searches, which netted a speed boost over the SSE4.2 code I had initially written.

2013-01-08t1402: work around shell quoting issue on NetBSDLibravatar René Scharfe1-2/+4
The test fails for me on NetBSD 6.0.1 and reports: ok 1 - ref name '' is invalid ok 2 - ref name '/' is invalid ok 3 - ref name '/' is invalid with options --allow-onelevel ok 4 - ref name '/' is invalid with options --normalize error: bug in the test script: not 2 or 3 parameters to test-expect-success The alleged bug is in this line: invalid_ref NOT_MINGW '/' '--allow-onelevel --normalize' invalid_ref() constructs a test case description using its last argument, but the shell seems to split it up into two pieces if it contains a space. Minimal test case: # on NetBSD with /bin/sh $ a() { echo $#-$1-$2; } $ t="x"; a "${t:+$t}" 1-x- $ t="x y"; a "${t:+$t}" 2-x-y $ t="x y"; a "${t:+x y}" 1-x y- # and with bash $ t="x y"; a "${t:+$t}" 1-x y- $ t="x y"; a "${t:+x y}" 1-x y- This may be a bug in the shell, but here's a simple workaround: Construct the description string first and store it in a variable, and then use that to call test_expect_success().

2011-10-13t1402-check-ref-format: skip tests of refs beginning with slash on WindowsLibravatar Johannes Sixt1-36/+52
Bash on Windows converts program arguments that look like absolute POSIX paths to their Windows form, i.e., drive-letter-colon format. For this reason, those tests in t1402 that check refs that begin with a slash do not work as expected on Windows: valid_ref tests are doomed to fail, and invalid_ref tests fail for the wrong reason (that there is a colon rather than that they begin with a slash). Skip these tests. Signed-off-by: Johannes Sixt <j6t@kdbg.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2011-10-05Change check_refname_format() to reject unnormalized refnamesLibravatar Michael Haggerty1-8/+23
Since much of the infrastructure does not work correctly with unnormalized refnames, change check_refname_format() to reject them. Similarly, change "git check-ref-format" to reject unnormalized refnames by default. But add an option --normalize, which causes "git check-ref-format" to normalize the refname before checking its format, and print the normalized refname. This is exactly the behavior of the old --print option, which is retained but deprecated. Signed-off-by: Michael Haggerty <mhagger@alum.mit.edu> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2011-10-05Do not allow ".lock" at the end of any refname componentLibravatar Michael Haggerty1-4/+4
Allowing any refname component to end with ".lock" is looking for trouble; for example, $ git br foo.lock/bar $ git br foo fatal: Unable to create '[...]/.git/refs/heads/foo.lock': File exists.

2011-10-05Change check_ref_format() to take a flags argumentLibravatar Michael Haggerty1-5/+1
Change check_ref_format() to take a flags argument that indicates what is acceptable in the reference name (analogous to "git check-ref-format"'s "--allow-onelevel" and "--refspec-pattern"). This is more convenient for callers and also fixes a failure in the test suite (and likely elsewhere in the code) by enabling "onelevel" and "refspec-pattern" to be allowed independently of each other. Also rename check_ref_format() to check_refname_format() to make it obvious that it deals with refnames rather than references themselves.

2011-10-05git check-ref-format: add options --allow-onelevel and --refspec-patternLibravatar Michael Haggerty1-7/+81
Also add tests of the new options. (Actually, one big reason to add the new options is to make it easy to test check_ref_format(), though the options should also be useful to other scripts.) Interpret the result of check_ref_format() based on which types of refnames are allowed. However, because check_ref_format() can only return a single value, one test case is still broken. Specifically, the case "git check-ref-format --onelevel '*'" incorrectly succeeds because check_ref_format() returns CHECK_REF_FORMAT_ONELEVEL for this refname even though the refname is also CHECK_REF_FORMAT_WILDCARD. The type of check that leads to this failure is used elsewhere in "real" code and could lead to bugs; it will be fixed over the next few commits.

2011-08-25check-ref-format --print: Normalize refnames that start with slashesLibravatar Michael Haggerty1-0/+6
When asked if "refs///heads/master" is valid, check-ref-format says "Yes, it is well formed", and when asked to print canonical form, it shows "refs/heads/master". This is so that it can be tucked after "$GIT_DIR/" to form a valid pathname for a loose ref, and we normalize a pathname like "$GIT_DIR/refs///heads/master" to de-dup the slashes in it. Similarly, when asked if "/refs/heads/master" is valid, check-ref-format says "Yes, it is Ok", but the leading slash is not removed when printing, leading to "$GIT_DIR//refs/heads/master". Fix it to make sure such leading slashes are removed. Add tests that such refnames are accepted and normalized correctly.

2009-10-12git check-ref-format --printLibravatar Junio C Hamano1-0/+17
Tolerating empty path components in ref names means each ref does not have a unique name. This creates difficulty for porcelains that want to see if two branches are equal. Add a helper associating to each ref a canonical name. If a user asks a porcelain to create a ref "refs/heads//master", the porcelain can run "git check-ref-format --print refs/heads//master" and only deal with "refs/heads/master" from then on.
