builtin-branch.c: optimize --merged and --no-merged "git branch --no-merged $commit" used to compute the merge base between the tip of each and every branch with the named $commit, but this was wasteful when you have many branches. Inside append_ref() we literally ran has_commit() between the tip of the branch and the merge_filter_ref. Instead, we can let the revision machinery traverse the history as if we are running: $ git rev-list --branches --not $commit by queueing the tips of branches we encounter as positive refs (this mimicks the "--branches" option in the above command line) and then appending the merge_filter_ref commit as a negative one, and finally calling prepare_revision_walk() to limit the list.. After the traversal is done, branch tips that are reachable from $commit are painted UNINTERESTING; they are already fully contained in $commit (i.e. --merged). Tips that are not painted UNINTERESTING still have commits that are not reachable from $commit, thus "--no-merged" will show them.

color: delay auto-color decision until point of use 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.

Avoid unnecessary "if-before-free" tests. This change removes all obvious useless if-before-free tests. E.g., it replaces code like this: if (some_expression) free (some_expression); with the now-equivalent: free (some_expression); It is equivalent not just because POSIX has required free(NULL) to work for a long time, but simply because it has worked for so long that no reasonable porting target fails the test. Here's some evidence from nearly 1.5 years ago: http://www.winehq.org/pipermail/wine-patches/2006-October/031544.html FYI, the change below was prepared by running the following: git ls-files -z | xargs -0 \ perl -0x3b -pi -e \ 's/\bif\s*\(\s*(\S+?)(?:\s*!=\s*NULL)?\s*\)\s+(free\s*\(\s*\1\s*\))/$2/s' Note however, that it doesn't handle brace-enclosed blocks like "if (x) { free (x); }". But that's ok, since there were none like that in git sources. Beware: if you do use the above snippet, note that it can produce syntactically invalid C code. That happens when the affected "if"-statement has a matching "else". E.g., it would transform this if (x) free (x); else foo (); into this: free (x); else foo (); There were none of those here, either. If you're interested in automating detection of the useless tests, you might like the useless-if-before-free script in gnulib: [it *does* detect brace-enclosed free statements, and has a --name=S option to make it detect free-like functions with different names] http://git.sv.gnu.org/gitweb/?p=gnulib.git;a=blob;f=build-aux/useless-if-before-free Addendum: Remove one more (in imap-send.c), spotted by Jean-Luc Herren <jlh@gmx.ch>.

builtin-branch.c: optimize --merged and --no-merged "git branch --no-merged $commit" used to compute the merge base between the tip of each and every branch with the named $commit, but this was wasteful when you have many branches. Inside append_ref() we literally ran has_commit() between the tip of the branch and the merge_filter_ref. Instead, we can let the revision machinery traverse the history as if we are running: $ git rev-list --branches --not $commit by queueing the tips of branches we encounter as positive refs (this mimicks the "--branches" option in the above command line) and then appending the merge_filter_ref commit as a negative one, and finally calling prepare_revision_walk() to limit the list.. After the traversal is done, branch tips that are reachable from $commit are painted UNINTERESTING; they are already fully contained in $commit (i.e. --merged). Tips that are not painted UNINTERESTING still have commits that are not reachable from $commit, thus "--no-merged" will show them.

check_ref_format(): tighten refname rules This changes the rules for refnames to forbid: (1) a refname that contains "@{" in it. Some people and foreign SCM converter may have named their branches as frotz@24 and we still want to keep supporting it. However, "git branch frotz@{24}" is a disaster. It cannot even checked out because "git checkout frotz@{24}" will interpret it as "detach the HEAD at twenty-fourth reflog entry of the frotz branch". (2) a refname that ends with a dot. We already reject a path component that begins with a dot, primarily to avoid ambiguous range interpretation. If we allowed ".B" as a valid ref, it is unclear if "A...B" means "in dot-B but not in A" or "either in A or B but not in both". But for this to be complete, we need also to forbid "A." to avoid "in B but not in A-dot". This was not a problem in the original range notation, but we should have added this restriction when three-dot notation was introduced. Unlike "no dot at the beginning of any path component" rule, this rule does not have to be "no dot at the end of any path component", because you cannot abbreviate the tail end away, similar to you can say "dot-B" to mean "refs/heads/dot-B". For these reasons, it is not likely people created branches with these names on purpose, but we have allowed such names to be used for quite some time, and it is possible that people created such branches by mistake or by accident. To help people with branches with such unfortunate names to recover, we still allow "branch -d 'bad.'" to delete such branches, and also allow "branch -m bad. good" to rename them.
