2014-10-15refs.c: change resolve_ref_unsafe reading argument to be a flags fieldLibravatar Ronnie Sahlberg1-2/+5
resolve_ref_unsafe takes a boolean argument for reading (a nonexistent ref resolves successfully for writing but not for reading). Change this to be a flags field instead, and pass the new constant RESOLVE_REF_READING when we want this behaviour. While at it, swap two of the arguments in the function to put output arguments at the end. As a nice side effect, this ensures that we can catch callers that were unaware of the new API so they can be audited. Give the wrapper functions resolve_refdup and read_ref_full the same treatment for consistency.

"rev-parse --verify --quiet $name" is meant to quietly exit with a non-zero status when $name is not a valid object name, but still gave error messages in some cases. * da/rev-parse-verify-quiet: stash: prefer --quiet over shell redirection of the standard error stream refs: make rev-parse --quiet actually quiet t1503: use test_must_be_empty Documentation: a note about stdout for git rev-parse --verify --quiet
2014-09-19refs: make rev-parse --quiet actually quietLibravatar David Aguilar1-2/+3
When a reflog is deleted, e.g. when "git stash" clears its stashes, "git rev-parse --verify --quiet" dies: fatal: Log for refs/stash is empty. The reason is that the get_sha1() code path does not allow us to suppress this message. Pass the flags bitfield through get_sha1_with_context() so that read_ref_at() can suppress the message. Use get_sha1_with_context1() instead of get_sha1() in rev-parse so that the --quiet flag is honored. Signed-off-by: David Aguilar <davvid@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

A call to "dwim_ref(name, len, flags, &ref)" will allocate a new string in "ref" to return the exact ref we found. We do not consistently free it in all code paths, leading to small leaks. The worst is in get_sha1_basic, which may be called many times (e.g., by "cat-file --batch"), though it is relatively unlikely, as it only triggers on a bogus reflog specification.

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).

2011-08-19want_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.

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.
