2017-07-13ref-filter: consult want_color() before emitting colorsLibravatar Jeff King1-0/+1
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.

2017-07-13rev-list: pass diffopt->use_colors through to pretty-printLibravatar Jeff King1-0/+1
When rev-list pretty-prints a commit, it creates a new pretty_print_context and copies items from the rev_info struct. We don't currently copy the "use_color" field, though. Nobody seems to have noticed because the only part of pretty.c that cares is the %C(auto,...) placeholder, and presumably not many people use that with the rev-list plumbing (as opposed to with git-log). It will become more noticeable in a future patch, though, when we start treating all user-format colors as auto-colors (in which case it would become impossible to format colors with rev-list, even with --color=always).

2017-07-13for-each-ref: load config earlierLibravatar Jeff King1-3/+2
In most commands we load config before parsing command line options, since it lets the latter override the former with a simple variable assignment. In the case of for-each-ref, though, we do it in the reverse order. This is OK with the current code, since there's no interaction between the config and command-line options. However, as the ref-filter code starts to care about config during verify_ref_format(), we'll want to make sure the config is loaded. Let's bump the config to the usual spot near the top of the function. We can drop the comment there; it's impossible to keep a "why we load the config" comment like this up to date with every config option we might be interested in. And indeed, it's already stale; we'd care about core.abbrev, for instance, when %(objectname:short) is used. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-07-13color: check color.ui in git_default_config()Libravatar Jeff King4-5/+4
Back in prehistoric times, our decision on whether or not to show color by default relied on using a config callback that either did or didn't load color config like color.diff. When we introduced color.ui, we put it in the same boat: commands had to manually respect it by using git_color_config() or its git_color_default_config() convenience wrapper. But in 4c7f1819b (make color.ui default to 'auto', 2013-06-10), that changed. Since then, we default color.ui to auto in all programs, meaning that even plumbing commands like "git diff-tree --pretty" might colorize the output. Nobody seems to have complained in the intervening years, presumably because the "is stdout a tty" check does a good job of catching the right cases. But that leaves an interesting curiosity: color.ui defaults to auto even in plumbing, but you can't actually _disable_ the color via config. So if you really hate color and set "color.ui" to false, diff-tree will still show color (but porcelain like git-diff won't). Nobody noticed that either, probably because very few people disable color. One could argue that the plumbing should _always_ disable color unless an explicit --color option is given on the command line. But in practice, this creates a lot of complications for scripts which do want plumbing to show user-visible output. They can't just pass "--color" blindly; they need to check the user's config and decide what to send. Given that nobody has complained about the current behavior, let's assume it's a good path, and follow it to its conclusion: supporting color.ui everywhere. Note that you can create havoc by setting color.ui=always in your config, but that's more or less already the case. We could disallow it entirely, but it is handy for one-offs like: git -c color.ui=always foo >not-a-tty when "foo" does not take a --color option itself.

2017-07-13ref-filter: provide a function for parsing sort optionsLibravatar Jeff King1-25/+1
The ref-filter module currently provides a callback suitable for parsing command-line --sort options. But since git-tag also supports the tag.sort config option, it needs a function whose implementation is quite similar, but with a slightly different interface. The end result is that builtin/tag.c has a copy-paste of parse_opt_ref_sorting(). Instead, let's provide a function to parse an arbitrary sort string, which we can then trivially wrap to make the parse_opt variant.

2017-07-13ref-filter: abstract ref format into its own structLibravatar Jeff King4-37/+41
The ref-filter module provides routines for formatting a ref for output. The fundamental interface for the format is a "const char *" containing the format, and any additional options need to be passed to each invocation of show_ref_array_item. Instead, let's make a ref_format struct that holds the format, along with any associated format options. That will make some enhancements easier in the future: 1. new formatting options can be added without disrupting existing callers 2. some state can be carried in the struct rather than as global variables For now this just has the text format itself along with the quote_style option, but we'll add more fields in future patches.

2017-07-13check return value of verify_ref_format()Libravatar Jeff King3-5/+10
Users of the ref-filter code must call verify_ref_format() before formatting any refs, but most ignore its return value. This means we may print an error on a syntactically bogus pattern, but keep going anyway. In most cases this results in a fatal error when we actually try to format a ref. But if you have no refs to show at all, then the behavior is confusing: git prints the error from verify_ref_format(), then exits with code 0 without showing any output. Let's instead abort immediately if we know we have a bogus format. We'll output the usage information if we have it handy (just like the existing call in cmd_for_each_ref() does), and otherwise just die().

We set the current and local branch colors at the top of the build_format() function. Let's do the same for the remote color.

Since 949af0684 (branch: use ref-filter printing APIs, 2017-01-10), git-branch's output is generated by passing a custom format to the ref-filter code. This format forgot to pass BRANCH_COLOR_LOCAL, meaning that local branches (besides the current one) were never colored at all. We can add it in the %(if) block where we decide whether the branch is "current" or merely "local". Note that this means the current/local coloring is either/or. You can't set: [color "branch"] local = blue current = bold and expect the current branch to be "bold blue". This matches the pre-949af0684 behavior.

2017-07-09branch: only perform HEAD check for local branchesLibravatar Jeff King1-1/+2
When assembling the ref-filter format to show "git branch" output, we put the "%(if)%(HEAD)" conditional at the start of the overall format. But there's no point in checking whether a remote branch matches HEAD, as it never will. The check should go inside the local conditional; we assemble that format inside the "local" strbuf. By itself, this is just a minor optimization. But in a future patch, we'll need this refactoring to fix local-branch coloring.

2017-06-21sha1_file: rename LOOKUP_REPLACE_OBJECTLibravatar Jonathan Tan1-2/+3
The LOOKUP_REPLACE_OBJECT flag controls whether the lookup_replace_object() function is invoked by sha1_object_info_extended(), read_sha1_file_extended(), and lookup_replace_object_extended(), but it is not immediately clear which functions accept that flag. Therefore restrict this flag to only sha1_object_info_extended(), renaming it appropriately to OBJECT_INFO_LOOKUP_REPLACE and adding some documentation. Update read_sha1_file_extended() to have a boolean parameter instead, and delete lookup_replace_object_extended(). parse_sha1_header() also passes this flag to parse_sha1_header_extended() since commit 46f0344 ("sha1_file: support reading from a loose object of unknown type", 2015-05-03), but that has had no effect since that commit.

The LOOKUP_UNKNOWN_OBJECT flag was introduced in commit 46f0344 ("sha1_file: support reading from a loose object of unknown type", 2015-05-03) in order to support a feature in cat-file subsequently introduced in commit 39e4ae3 ("cat-file: teach cat-file a '--allow-unknown-type' option", 2015-05-03). Despite its name and location in cache.h, this flag is used neither in read_sha1_file_extended() nor in any of the lookup functions, but used only in sha1_object_info_extended(). Therefore rename this flag to OBJECT_INFO_ALLOW_UNKNOWN_TYPE, taking the name of the cat-file flag that invokes this feature, and move it closer to the declaration of sha1_object_info_extended(). Also add documentation for this flag. OBJECT_INFO_ALLOW_UNKNOWN_TYPE is defined to 2, not 1, to avoid conflicting with LOOKUP_REPLACE_OBJECT. Avoidance of this conflict is necessary because sha1_object_info_extended() supports both flags.

2017-06-16*.[ch] refactoring: make use of the FREE_AND_NULL() macroLibravatar Ævar Arnfjörð Bjarmason2-15/+6
Replace occurrences of `free(ptr); ptr = NULL` which weren't caught by the coccinelle rule. These fall into two categories: - free/NULL assignments one after the other which coccinelle all put on one line, which is functionally equivalent code, but very ugly. - manually spotted occurrences where the NULL assignment isn't right after the free() call.
