| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we show "branch@{0}", we format into a fixed-size buffer using sprintf.

* | | | | convert "enum date_mode" into a structJeff King2015-06-291-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In preparation for adding date modes that may carry extra information beyond the mode itself, this patch converts the date_mode enum into a struct. Most of the conversion is fairly straightforward; we pass the struct as a pointer and dereference the type field where necessary. Locations that declare a date_mode can use a "{}" constructor. However, the tricky case is where we use the enum labels as constants, like: show_date(t, tz, DATE_NORMAL); Ideally we could say: show_date(t, tz, &{ DATE_NORMAL }); but of course C does not allow that. Likewise, we cannot cast the constant to a struct, because we need to pass an actual address. Our options are basically: 1. Manually add a "struct date_mode d = { DATE_NORMAL }" definition to each caller, and pass "&d". This makes the callers uglier, because they sometimes do not even have their own scope (e.g., they are inside a switch statement). 2. Provide a pre-made global "date_normal" struct that can be passed by address. We'd also need "date_rfc2822", "date_iso8601", and so forth. But at least the ugliness is defined in one place. 3. Provide a wrapper that generates the correct struct on the fly. The big downside is that we end up pointing to a single global, which makes our wrapper non-reentrant. But show_date is already not reentrant, so it does not matter. This patch implements 3, along with a minor macro to keep the size of the callers sane.

To aid this transition, implement an adapter that can be used to wrap old-style functions matching the old typedef, which is now called "each_ref_sha1_fn"), and make such functions callable via the new interface. This requires the old function and its cb_data to be wrapped in a "struct each_ref_fn_sha1_adapter", and that object to be used as the cb_data for an adapter function, each_ref_fn_adapter(). This is an enormous diff, but most of it consists of simple, mechanical changes to the sites that call any of the "for_each_ref" family of functions. Subsequent to this change, the call sites can be rewritten one by one to use the new interface.

"git show-branch" displays ancestry graph for all local branches. Unfortunately, "git show-branch --topics <rev>" only prints out the rev info for the given rev, and nothing else, e.g.: $ git show-branch --topics origin/master [origin/master] Sync with 2.3.3 While there is an option to add all remote-tracking branches (-r), and another to add all local+remote branches (-a), there is no option to add only local branches. Adding such an option could be considered, but a user would likely already expect that the above command line considers the lack of rev other than for --topics as meaning all local branches, like when there is no argument at all. Moreover, when using -r and -a along with --topics, the first local or remote-tracking branch, depending on alphabetic order is used instead of the one given after --topics (any rev given on the command line is actually simply ignored when either -r or -a is given). And if no rev is given at all, the fact that the first alphetical branch is the base of topics is probably not expected by users (Maybe --topics should always require one rev on the command line?) This change makes "show-branch --topics $rev" act as "show-branch --topics $rev $(git for-each-ref refs/heads --format='%(refname:short)')" "show-branch -r --topics $rev ..." act as "show-branch --topics $rev ... $(git for-each-ref refs/remotes --format='%(refname:short)')" instead of "show-branch --topics $(git for-each-ref refs/remotes --format='%(refname:short)')" and "show-branch -a --topics $rev ..." act as "show-branch --topics $rev ... $(git for-each-ref refs/heads refs/remotes --format='%(refname:short)')" instead of "show-branch --topics $(git for-each-ref refs/heads refs/remotes --format='%(refname:short)')" Signed-off-by: Mike Hommey <mh@glandium.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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>
* | show-branch: use strbuf instead of static bufferJeff King2013-04-061-9/+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).

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.

* color: delay auto-color decision until point of useJeff King2011-08-191-2/+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.

* git_config_colorbool: refactor stdout_is_tty handlingJeff King2011-08-181-1/+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. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
