2017-07-13ref-filter: consult want_color() before emitting colorsLibravatar Jeff King1-11/+26
When color placeholders like %(color:red) are used in a ref-filter format, we unconditionally output the colors, even if the user has asked us for no colors. This usually isn't a problem when the user is constructing a --format on the command line, but it means we may do the wrong thing when the format is fed from a script or alias. For example: $ git config alias.b 'branch --format=%(color:green)%(refname)' $ git b --no-color should probably omit the green color. Likewise, running: $ git b >branches should probably also omit the color, just as we would for all baked-in coloring (and as we recently started to do for user-specified colors in --pretty formats). This commit makes both of those cases work by teaching the ref-filter code to consult want_color() before outputting any color. The color flag in ref_format defaults to "-1", which means we'll consult color.ui, which in turn defaults to the usual isatty() check on stdout. However, callers like git-branch which support their own color config (and command-line options) can override that. The new tests independently cover all three of the callers of ref-filter (for-each-ref, tag, and branch). Even though these seem redundant, it confirms that we've correctly plumbed through all of the necessary config to make colors work by default.

2017-07-13t: use test_decode_color rather than literal ANSI codesLibravatar Jeff King1-10/+8
When we put literal ANSI terminal codes into our test scripts, it makes diffs on those scripts hard to read (the colors may be indistinguishable from diff coloring, or in the case of a reset, may not be visible at all). Some scripts get around this by including human-readable names and converting to literal codes with a git-config hack. This makes the actual code diffs look OK, but test_cmp output suffers from the same problem. Let's use test_decode_color instead, which turns the codes into obvious text tags.

In one test, we use "git checkout --orphan HEAD" to create an unborn branch. Confusingly, the resulting branch is named "refs/heads/HEAD". The original probably meant something like: git checkout --orphan orphaned-branch HEAD Let's just use "orphaned-branch" here to make this less confusing.

2017-02-07ref-filter: resurrect "strip" as a synonym to "lstrip"Libravatar Junio C Hamano1-0/+12
We forgot that "strip" was introduced at 0571979bd6 ("tag: do not show ambiguous tag names as "tags/foo"", 2016-01-25) as part of Git 2.8 (and 2.7.1) when we started calling this "lstrip" to make it easier to explain the new "rstrip" operation. We shouldn't have renamed the existing one; "lstrip" should have been a new synonym that means the same thing as "strip". Scripts in the wild are surely using the original form already.

Modify the 'lstrip' option to also take a negative number '<N>' which would strip from the left as necessary and _leave_ behind only 'N' slash-separated path components from the right-most end.

Currently when we use the 'lstrip=<N>' option, if 'N' is greater than the number of components available in the refname, we abruptly end program execution by calling die(). This behavior is undesired since a single refname with few components could end program execution.

2016-01-26tag: do not show ambiguous tag names as "tags/foo"Libravatar Jeff King1-0/+12
Since b7cc53e9 (tag.c: use 'ref-filter' APIs, 2015-07-11), git-tag has started showing tags with ambiguous names (i.e., when both "heads/foo" and "tags/foo" exists) as "tags/foo" instead of just "foo". This is both: - pointless; the output of "git tag" includes only refs/tags, so we know that "foo" means the one in "refs/tags". and - ambiguous; in the original output, we know that the line "foo" means that "refs/tags/foo" exists. In the new output, it is unclear whether we mean "refs/tags/foo" or "refs/tags/tags/foo". The reason this happens is that commit b7cc53e9 switched git-tag to use ref-filter's "%(refname:short)" output formatting, which was adapted from for-each-ref. This more general code does not know that we care only about tags, and uses shorten_unambiguous_ref to get the short-name. We need to tell it that we care only about "refs/tags/", and it should shorten with respect to that value. In theory, the ref-filter code could figure this out by us passing FILTER_REFS_TAGS. But there are two complications there: 1. The handling of refname:short is deep in formatting code that does not even have our ref_filter struct, let alone the arguments to the filter_ref struct. 2. In git v2.7.0, we expose the formatting language to the user. If we follow this path, it will mean that "%(refname:short)" behaves differently for "tag" versus "for-each-ref" (including "for-each-ref refs/tags/"), which can lead to confusion. Instead, let's add a new modifier to the formatting language, "strip", to remove a specific set of prefix components. This fixes "git tag", and lets users invoke the same behavior from their own custom formats (for "tag" or "for-each-ref") while leaving ":short" with its same consistent meaning in all places. We introduce a test in t7004 for "git tag", which fails without this patch. We also add a similar test in t3203 for "git branch", which does not actually fail. But since it is likely that "branch" will eventually use the same formatting code, the test helps defend against future regressions.

This is shorter, gets rid of some tests that have their "expected" setup outside of a test_expect_success block, and lets us organize the changes better (e.g., putting "refname:short" near "refname").

2015-07-20strbuf: make strbuf_addftime more robustLibravatar Jeff King1-0/+10
The return value of strftime is poorly designed; when it returns 0, the caller cannot tell if the buffer was not large enough, or if the output was actually 0 bytes. In the original implementation of strbuf_addftime, we simply punted and guessed that our 128-byte hint would be large enough. We can do better, though, if we're willing to treat strftime like less of a black box. We can munge the incoming format to make sure that it never produces 0-length output, and then "fix" the resulting output. That lets us reliably grow the buffer based on strftime's return value.

2015-01-12for-each-ref: always check stat_tracking_info()'s return valueLibravatar Raphael Kubo da Costa1-0/+13
The code handling %(upstream:track) and %(upstream:trackshort) assumed that it always had a valid branch that had been sanitized earlier in populate_value(), and thus did not check the return value of the call to stat_tracking_info(). While there is indeed some sanitization code that basically corresponds to stat_tracking_info() returning 0 (no base branch set), the function can also return -1 when the base branch did exist but has since then been deleted. In this case, num_ours and num_theirs had undefined values and a call to `git for-each-ref --format="%(upstream:track)"` could print spurious values such as [behind -111794512] [ahead 38881640, behind 5103867] even for repositories with one single commit. Verify stat_tracking_info()'s return value and do not print anything if it returns -1.

2013-10-30for-each-ref: avoid loading objects to print %(objectname)Libravatar Jeff King1-0/+4
If you ask for-each-ref to print each ref and its object, like: git for-each-ref --format='%(objectname) %(refname)' this should involve little more work than looking at the ref files (and packed-refs) themselves. However, for-each-ref will actually load each object from disk just to print its sha1. For most repositories, this isn't a big deal, but it can be noticeable if you have a large number of refs to print. Here are best-of-five timings for the command above on a repo with ~10K refs: [before] real 0m0.112s user 0m0.092s sys 0m0.016s [after] real 0m0.014s user 0m0.012s sys 0m0.000s This patch checks for %(objectname) and %(objectname:short) before we actually parse the object (and the rest of the code is smart enough to avoid parsing if we have filled all of our placeholders). Note that we can't simply move the objectname parsing code into the early loop. If the "deref" form %(*objectname) is used, then we do need to parse the object in order to peel the tag. So instead of moving the code, we factor it out into a separate function that can be called for both cases. While we're at it, we add some basic tests for the dereferenced placeholders, which were not tested at all before. This helps ensure we didn't regress that case.

2008-09-05for-each-ref: `:short` format for `refname`Libravatar Bert Wesarg1-0/+44
Tries to shorten the refname to a non-ambiguous name. Szeder Gábor noticed that the git bash completion takes a tremendous amount of time to strip leading components from heads and tags refs (i.e. refs/heads, refs/tags, ...). He proposed a new atom called 'refbasename' which removes at most two leading components from the ref name. I myself, proposed a more dynamic solution, which strips off common leading components with the matched pattern. But the current bash solution and both proposals suffer from one mayor problem: ambiguous refs. A ref is ambiguous, if it resolves to more than one full refs. I.e. given the refs refs/heads/xyzzy and refs/tags/xyzzy. The (short) ref xyzzy can point to both refs. ( Note: Its irrelevant whether the referenced objects are the same or not. ) This proposal solves this by checking for ambiguity of the shorten ref name. The shortening is done with the same rules for resolving refs but in the reverse order. The short name is checked if it resolves to a different ref. To continue the above example, the output would be like this: heads/xyzzy xyzzy So, if you want just tags, xyzzy is not ambiguous, because it will resolve to a tag. If you need the heads you get a also a non-ambiguous short form of the ref. To integrate this new format into the bash completion to get only non-ambiguous refs is beyond the scope of this patch.

2008-06-26improve for-each-ref test scriptLibravatar Jeff King1-17/+70
Previously, we did a sanity check by doing for-each-ref using each possible format atom. However, we never checked the actual output produced by that atom, which recently let an obvious bug go undetected for some time. While we're at it, also clean up a few '!' into test_must_fail.

2008-05-24tests: do not use implicit "git diff --no-index"Libravatar Junio C Hamano1-12/+12
As a general principle, we should not use "git diff" to validate the results of what git command that is being tested has done. We would not know if we are testing the command in question, or locating a bug in the cute hack of "git diff --no-index". Rather use test_cmp for that purpose.
