| * | | | | | | | | | | | | | | | | | | | t9903: remove redundant testsEduardo R. D'Avila2013-06-261-114/+1

Remove tests for zsh. Keep one minimal test that stress the difference in codepaths for bash and zsh. Suggested-by: SZEDER Gábor <szeder@ira.uka.de> Signed-off-by: Eduardo R.

It has duplicated code to handle color codes for bash and zsh shells. __git_ps1() also has duplicated logic to build the prompt gitstring. Remove duplication of logic to build gitstring in __git_ps1_colorize_gitstring() and __git_ps1(). Leave in __git_ps1_colorize_gitstring() only logic to set color codes. Signed-off-by: Eduardo R.

" or "squash! " after the first. This supports the case when a git commit --fixup/--squash referred to an earlier fixup/squash instead of the original commit (whether intentionally, as when the user expressly meant to note that the commit fixes an earlier fixup; or inadvertently, as when the user meant to refer to the original commit with :/msg; or out of laziness, as when the user could remember how to refer to the fixup but not the original). In the todo list, the full commit message is preserved, in case it provides useful cues to the user. A test helper set_cat_todo_editor is introduced to check this.

This command not only checks that the 'refs/stash' ref exists but also, well, verifies that it's a valid ref. However, we don't need to be that thorough for the bash prompt. We can omit that verification and only check whether 'refs/stash' exists or not. Since 'git pack-refs' never packs 'refs/stash', it's a matter of checking the existence of a ref file. Perform this check using only bash builtins to spare the overhead of fork()+exec()ing a git process. Also run 'git pack-refs --all' in the corresponding test to document that the prompt script depends on 'git pack-refs' not packing 'refs/stash' and to catch possible breakages should this behavior ever change.

However, that makes sense only when HEAD points to a valid commit: on an unborn branch the failure of said command would be caused by the invalid HEAD, not by changes in the index. Therefore, __git_ps1() first checks for a valid HEAD by running 'git rev-parse --quiet --verify HEAD'. Since the previous patch we implicitly check HEAD's validity by running 'git rev-parse ... --short HEAD', making the dirty status indicator's 'git rev-parse' check redundant. It's sufficient to check for non-emptyness of the variable holding the abbreviated commit object name, thereby sparing the overhead of fork()+exec()ing a git process.

This imposes the overhead of fork()ing a subshell and fork()+exec()ing a git process. Avoid this overhead by combining this command substitution with the "main" 'git rev-parse' execution for getting the path to the .git directory & co. This means that we'll look for the abbreviated commit object name even when it's not necessary, because we're on a branch or the detached HEAD can be described. It doesn't matter, however, because once 'git rev-parse' is up and running to fulfill all those other queries, the additional overhead of looking for the abbreviated commit object name is not measurable because it's lost in the noise. There is a caveat, however, when we are on an unborn branch, because in that case HEAD doesn't point to a valid commit, hence the query for the abbreviated commit object name fails. Therefore, '--short HEAD' must be the last options to 'git rev-parse' in order to get all the other necessary information for the prompt even on an unborn branch. Furthermore, in that case, and in that case only, 'git rev-parse' doesn't output the last line containing the abbreviated commit object name, obviously, so we have to take care to only parse it if 'git rev-parse' exited without any error.

Naturally, this imposes the overhead of fork()ing three subshells and fork()+exec()ing three git commands. Combine these four 'git rev-parse' queries into a single one and use bash parameter expansions to parse the combined output, i.e. to separate the path to the .git directory from the true/false of '--is-inside-git-dir', etc. This way we can eliminate two of the three subshells and git commands.

This imposes the overhead of fork()ing a subshell and fork()+exec()ing a git process. Since HEAD is in most cases a single-line file and the symbolic ref format is quite simple to recognize and parse, read and parse it using only bash builtins, thereby sparing all that fork()+exec() overhead. Don't display the git prompt if reading HEAD fails, because a readable HEAD is required for a git repository. HEAD can also be a symlink symbolic ref (due to 'core.preferSymlinkRefs'), so use bash builtins for reading HEAD only when HEAD is not a symlink. Signed-off-by: SZEDER Gábor <szeder@ira.uka.de>

However, the former two is only necessary for the completion script but makes no sense for the bash prompt, while the latter shortcuts are performance optimizations __git_ps1() can do without (they just avoid the overhead of fork()+exec()ing a git process). Run 'git rev-parse --git-dir' directly in __git_ps1(), because it will allow this patch series to combine several $(git rev-parse ...) command substitutions in the main code path, and the overall performance benefit will far outweigh the loss of those few shortcuts in __gitdir(). Furthermore, since __gitdir() is not needed anymore for the prompt, remove it from the prompt script finally eliminating its duplication between the prompt and completion scripts. Also remove the comment from the completion script warning about this code duplication. Signed-off-by: SZEDER Gábor <szeder@ira.uka.de>

The actual value of the timestamp, however, does not matter very much; only their relative ordering does. Introduce another helper to expand only the suffix of the timestamp to a full timestamp to make the lines shorter, and use it in this helper. Also, because all the commits in the test are made with specific GIT_COMMITTER_DATE, stop unsetting it at the end of the helper. We'll be specifying the author timestamp to these test commits in a later patch, which will be helped with this change. Also remove a test that was commented-out from t6003; it used to test a commit with the same parent listed twice, which was allowed by mistake but was fixed long time ago.

The most typical use of the list is to add commits that are newly discovered to it, keep the list sorted by commit timestamp, pick up the newest one from the list, and keep digging. The cost of keeping the singly linked list sorted is nontrivial, and this typical use pattern better matches a priority queue. Introduce a prio-queue structure, that can be used either as a LIFO stack, or a priority queue. This will be used in the next patch to hold in-flight commits during sort-in-topological-order. Tests and the idea to make it usable for any "void *" pointers to "things" are by Jeff King. Bugs are mine. Signed-off-by: Junio C Hamano <gitster@pobox.com>

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>

Update the "indegree" topological sort facility using it. To associate 32 flag bits with each commit, you can write: define_commit_slab(flag32, uint32); to declare "struct flag32" type, define an instance of it with struct flag32 flags; and initialize it by calling init_flag32(&flags); After that, a call to flag32_at() function uint32 *fp = flag32_at(&flags, commit); will return a pointer pointing at a uint32 for that commit. Once you are done with these flags, clean them up with clear_flag32(&flags); Callers that cannot hard-code how wide the data to be associated with the commit be at compile time can use the "_with_stride" variant to initialize the slab. Suppose you want to give one bit per existing ref, and paint commits down to find which refs are descendants of each commit. Saying typedef uint32 bits320[5]; define_commit_slab(flagbits, bits320); at compile time will still limit your code with hard-coded limit, because you may find that you have more than 320 refs at runtime. The code can declare a commit slab "struct flagbits" like this instead: define_commit_slab(flagbits, unsigned char); struct flagbits flags; and initialize it by: nrefs = ... count number of refs ... init_flagbits_with_stride(&flags, (nrefs + 7) / 8); so that unsigned char *fp = flagbits_at(&flags, commit); will return a pointer pointing at an array of 40 "unsigned char"s associated with the commit, once you figure out nrefs is 320 at runtime.

Each access may need two levels of indirections, but we only need to reallocate the first level array of pointers when we have to grow the table this way.

We would prefer to shrink the size of individual commit objects, which we may have to hold thousands of in-core. We could eject "indegree" field out from the commit object and represent it as a dynamic table based on the decoration infrastructure, but the decoration is meant for sparse annotation and is not a good match. Instead, let's try a different approach. - Assign an integer (commit->index) to each commit we keep in-core (reuse the space of "indegree" field for it); - When running the topological sort, allocate an array of integers in bulk (called "slab"), use the commit->index as an index into this array, and store the "indegree" information there. This does _not_ reduce the memory footprint of a commit object, but the commit->index can be used as the index to dynamically associate commits with other kinds of information as needed.
