2013-12-17Merge branch 'cc/starts-n-ends-with'Libravatar Junio C Hamano1-10/+10
Remove a few duplicate implementations of prefix/suffix comparison functions, and rename them to starts_with and ends_with. * cc/starts-n-ends-with: replace {pre,suf}fixcmp() with {starts,ends}_with() strbuf: introduce starts_with() and ends_with() builtin/remote: remove postfixcmp() and use suffixcmp() instead environment: normalize use of prefixcmp() by removing " != 0"
2013-12-05replace {pre,suf}fixcmp() with {starts,ends}_with()Libravatar Christian Couder1-10/+10
Leaving only the function definitions and declarations so that any new topic in flight can still make use of the old functions, replace existing uses of the prefixcmp() and suffixcmp() with new API functions. The change can be recreated by mechanically applying this: $ git grep -l -e prefixcmp -e suffixcmp -- \*.c | grep -v strbuf\\.c | xargs perl -pi -e ' s|!prefixcmp\(|starts_with\(|g; s|prefixcmp\(|!starts_with\(|g; s|!suffixcmp\(|ends_with\(|g; s|suffixcmp\(|!ends_with\(|g; ' on the result of preparatory changes in this series.

2013-08-05Replace deprecated OPT_BOOLEAN by OPT_BOOLLibravatar Stefan Beller1-14/+14
This task emerged from b04ba2bb (parse-options: deprecate OPT_BOOLEAN, 2011-09-27). All occurrences of the respective variables have been reviewed and none of them relied on the counting up mechanism, but all of them were using the variable as a true boolean.

2013-07-01Merge branch 'jc/topo-author-date-sort'Libravatar Junio C Hamano1-6/+8
"git log" learned the "--author-date-order" option, with which the output is topologically sorted and commits in parallel histories are shown intermixed together based on the author timestamp. * jc/topo-author-date-sort: t6003: add --author-date-order test topology tests: teach a helper to set author dates as well t6003: add --date-order test topology tests: teach a helper to take abbreviated timestamps t/lib-t6000: style fixes log: --author-date-order sort-in-topological-order: use prio-queue prio-queue: priority queue of pointers to structs toposort: rename "lifo" field
2013-06-11toposort: rename "lifo" fieldLibravatar Junio C Hamano1-6/+8
The primary invariant of sort_in_topological_order() is that a parent commit is not emitted until all children of it are. When traversing a forked history like this with "git log C E": A----B----C \ D----E we ensure that A is emitted after all of B, C, D, and E are done, B has to wait until C is done, and D has to wait until E is done. In some applications, however, we would further want to control how these child commits B, C, D and E on two parallel ancestry chains are shown. Most of the time, we would want to see C and B emitted together, and then E and D, and finally A (i.e. the --topo-order output). The "lifo" parameter of the sort_in_topological_order() function is used to control this behaviour. We start the traversal by knowing two commits, C and E. While keeping in mind that we also need to inspect E later, we pick C first to inspect, and we notice and record that B needs to be inspected. By structuring the "work to be done" set as a LIFO stack, we ensure that B is inspected next, before other in-flight commits we had known that we will need to inspect, e.g. E. When showing in --date-order, we would want to see commits ordered by timestamps, i.e. show C, E, B and D in this order before showing A, possibly mixing commits from two parallel histories together. When "lifo" parameter is set to false, the function keeps the "work to be done" set sorted in the date order to realize this semantics. After inspecting C, we add B to the "work to be done" set, but the next commit we inspect from the set is E which is newer than B. The name "lifo", however, is too strongly tied to the way how the function implements its behaviour, and does not describe what the behaviour _means_. Replace this field with an enum rev_sort_order, with two possible values: REV_SORT_IN_GRAPH_ORDER and REV_SORT_BY_COMMIT_DATE, and update the existing code. The mechanical replacement rule is: "lifo == 0" is equivalent to "sort_order == REV_SORT_BY_COMMIT_DATE" "lifo == 1" is equivalent to "sort_order == REV_SORT_IN_GRAPH_ORDER" Signed-off-by: Junio C Hamano <gitster@pobox.com>
2013-04-06show-branch: use strbuf instead of static bufferLibravatar Jeff King1-9/+8
When we generate relative names (e.g., "master~20^2"), we format the name into a static buffer, then xstrdup the result to attach it to the commit. Since the first thing we add into the static buffer is the already-computed name of the child commit, the names may get longer and longer as the traversal gets deeper, and we may eventually overflow the fixed-size buffer. Fix this by converting the fixed-size buffer into a dynamic strbuf. The performance implications should be minimal, as we end up allocating a heap copy of the name anyway (and now we can just detach the heap copy from the strbuf).

2011-12-13Rename resolve_ref() to resolve_ref_unsafe()Libravatar Nguyễn Thái Ngọc Duy1-1/+1
resolve_ref() may return a pointer to a shared buffer and can be overwritten by the next resolve_ref() calls. Callers need to pay attention, not to keep the pointer when the next call happens. Rename with "_unsafe" suffix to warn developers (or reviewers) before introducing new call sites.

2011-08-19want_color: automatically fallback to color.uiLibravatar Jeff King1-3/+0
All of the "do we want color" flags default to -1 to indicate that we don't have any color configured. This value is handled in one of two ways: 1. In porcelain, we check early on whether the value is still -1 after reading the config, and set it to the value of color.ui (which defaults to 0). 2. In plumbing, it stays untouched as -1, and want_color defaults it to off. This works fine, but means that every porcelain has to check and reassign its color flag. Now that want_color gives us a place to put this check in a single spot, we can do that, simplifying the calling code.

2011-08-19color: delay auto-color decision until point of useLibravatar Jeff King1-2/+2
When we read a color value either from a config file or from the command line, we use git_config_colorbool to convert it from the tristate always/never/auto into a single yes/no boolean value. This has some timing implications with respect to starting a pager. If we start (or decide not to start) the pager before checking the colorbool, everything is fine. Either isatty(1) will give us the right information, or we will properly check for pager_in_use(). However, if we decide to start a pager after we have checked the colorbool, things are not so simple. If stdout is a tty, then we will have already decided to use color. However, the user may also have configured color.pager not to use color with the pager. In this case, we need to actually turn off color. Unfortunately, the pager code has no idea which color variables were turned on (and there are many of them throughout the code, and they may even have been manipulated after the colorbool selection by something like "--color" on the command line). This bug can be seen any time a pager is started after config and command line options are checked. This has affected "git diff" since 89d07f7 (diff: don't run pager if user asked for a diff style exit code, 2007-08-12). It has also affect the log family since 1fda91b (Fix 'git log' early pager startup error case, 2010-08-24). This patch splits the notion of parsing a colorbool and actually checking the configuration. The "use_color" variables now have an additional possible value, GIT_COLOR_AUTO. Users of the variable should use the new "want_color()" wrapper, which will lazily determine and cache the auto-color decision.

2011-08-18git_config_colorbool: refactor stdout_is_tty handlingLibravatar Jeff King1-1/+1
Usually this function figures out for itself whether stdout is a tty. However, it has an extra parameter just to allow git-config to override the auto-detection for its --get-colorbool option. Instead of an extra parameter, let's just use a global variable. This makes calling easier in the common case, and will make refactoring the colorbool code much simpler.

This shrinks the top-level directory a bit, and makes it much more pleasant to use auto-completion on the thing. Instead of [torvalds@nehalem git]$ em buil<tab> Display all 180 possibilities?

NOTE! If you do this in a clean tree (no object files etc), or using an editor that has auto-completion rules that ignores '*.o' files, you won't see that annoying 'Display all 180 possibilities?' message - it will just show the choices instead. I think bash has some cut-off around 100 choices or something. So the reason I see this is that I'm using an odd editory, and thus don't have the rules to cut down on auto-completion. But you can simulate that by using 'ls' instead, or something similar. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
