2013-05-16revision.c: add BOTTOM flag for commitsLibravatar Kevin Bracey1-1/+2
When performing edge-based operations on the revision graph, it can be useful to be able to identify the INTERESTING graph's connection(s) to the bottom commit(s) specified by the user. Conceptually when the user specifies "A..B" (== B ^A), they are asking for the history from A to B. The first connection from A onto the INTERESTING graph is part of that history, and should be considered. If we consider only INTERESTING nodes and their connections, then we're really only considering the history from A's immediate descendants to B. This patch does not change behaviour, but adds a new BOTTOM flag to indicate the bottom commits specified by the user, ready to be used by following patches. We immediately use the BOTTOM flag to return collect_bottom_commits() to its original approach of examining the pending commit list rather than the command line. This will ensure alignment of the definition of "bottom" with future patches. Signed-off-by: Kevin Bracey <kevin@bracey.fi> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2013-05-16revision.c: Make --full-history consider more mergesLibravatar Kevin Bracey1-0/+1
History simplification previously always treated merges as TREESAME if they were TREESAME to any parent. While this was consistent with the default behaviour, this could be extremely unhelpful when searching detailed history, and could not be overridden. For example, if a merge had ignored a change, as if by "-s ours", then: git log -m -p --full-history -Schange file would successfully locate "change"'s addition but would not locate the merge that resolved against it. Futher, simplify_merges could drop the actual parent that a commit was TREESAME to, leaving it as a normal commit marked TREESAME that isn't actually TREESAME to its remaining parent. Now redefine a commit's TREESAME flag to be true only if a commit is TREESAME to _all_ of its parents. This doesn't affect either the default simplify_history behaviour (because partially TREESAME merges are turned into normal commits), or full-history with parent rewriting (because all merges are output). But it does affect other modes. The clearest difference is that --full-history will show more merges - sufficient to ensure that -m -p --full-history log searches can really explain every change to the file, including those changes' ultimate fate in merges. Also modify simplify_merges to recalculate TREESAME after removing a parent. This is achieved by storing per-parent TREESAME flags on the initial scan, so the combined flag can be easily recomputed. This fixes some t6111 failures, but creates a couple of new ones - we are now showing some merges that don't need to be shown.

2013-05-16revision.c: treat A...B merge bases as if manually specifiedLibravatar Kevin Bracey1-0/+1
The documentation assures users that "A...B" is defined as "A B --not $(git merge-base --all A B)". This wasn't in fact quite true, because the calculated merge bases were not sent to add_rev_cmdline(). The main effect of this was that although git rev-list --ancestry-path A B --not $(git merge-base --all A B) worked, the simpler form git rev-list --ancestry-path A...B failed with a "no bottom commits" error. Other potential users of bottom commits could also be affected by this problem, if they examine revs->cmdline_info; I came across the issue in my proposed history traversal refinements series. So ensure that the calculated merge bases are sent to add_rev_cmdline(), flagged with new 'whence' enum value REV_CMD_MERGE_BASE.

2012-12-22format-patch: add --reroll-count=$N optionLibravatar Junio C Hamano1-0/+1
The --reroll-count=$N option, when given a positive integer: - Adds " v$N" to the subject prefix specified. As the default subject prefix string is "PATCH", --reroll-count=2 makes it "PATCH v2". - Prefixes "v$N-" to the names used for output files. The cover letter, whose name is usually 0000-cover-letter.patch, becomes v2-0000-cover-letter.patch when given --reroll-count=2. This allows users to use the same --output-directory for multiple iterations of the same series, without letting the output for a newer round overwrite output files from the earlier rounds. The user can incorporate materials from earlier rounds to update the newly minted iteration, and use "send-email v2-*.patch" to send out the patches belonging to the second iteration easily.

2012-08-30teach log --no-walk=unsorted, which avoids sortingLibravatar Martin von Zweigbergk1-1/+5
When 'git log' is passed the --no-walk option, no revision walk takes place, naturally. Perhaps somewhat surprisingly, however, the provided revisions still get sorted by commit date. So e.g 'git log --no-walk HEAD HEAD~1' and 'git log --no-walk HEAD~1 HEAD' give the same result (unless the two revisions share the commit date, in which case they will retain the order given on the command line). As the commit that introduced --no-walk (8e64006 (Teach revision machinery about --no-walk, 2007-07-24)) points out, the sorting is intentional, to allow things like git log --abbrev-commit --pretty=oneline --decorate --all --no-walk to show all refs in order by commit date. But there are also other cases where the sorting is not wanted, such as <command producing revisions in order> | git log --oneline --no-walk --stdin To accomodate both cases, leave the decision of whether or not to sort up to the caller, by allowing --no-walk={sorted,unsorted}, defaulting to 'sorted' for backward-compatibility reasons.

The command line parser choked "git cherry-pick $name" when $name can be both revision name and a pathname, even though $name can never be a path in the context of the command. The issue the patch addresses is real, but the way it is implemented felt unnecessarily invasive a bit.

If a commit-ish passed to cherry-pick or revert happens to have a file of the same name, git complains that the argument is ambiguous and advises to use '--'. To make things worse, the '--' argument is removed by parse_options, und so passing '--' has no effect. Instead, always interpret cherry-pick/revert arguments as revisions.

2011-08-25revision: keep track of the end-user input from the command lineLibravatar Junio C Hamano1-0/+20
Given a complex set of revision specifiers on the command line, it is too late to look at the flags of the objects in the initial traversal list at the beginning of limit_list() in order to determine what the objects the end-user explicitly listed on the command line were. The process to move objects from the pending array to the traversal list may have marked objects that are not mentioned as UNINTERESTING, when handle_commit() marked the parents of UNINTERESTING commits mentioned on the command line by calling mark_parents_uninteresting(). This made "rev-list --ancestry-path ^A ..." to mistakenly list commits that are descendants of A's parents but that are not descendants of A itself, as ^A from the command line causes A and its parents marked as UNINTERESTING before coming to limit_list(), and we try to enumerate the commits that are descendants of these commits that are UNINTERESTING before we start walking the history. It actually is too late even if we inspected the pending object array before calling prepare_revision_walk(), as some of the same objects might have been mentioned twice, once as positive and another time as negative. The "rev-list --some-option A --not --all" command may want to notice, even if the resulting set is empty, that the user showed some interest in "A" and do something special about it. Prepare a separate array to keep track of what syntactic element was used to cause each object to appear in the pending array from the command line, and populate it as setup_revisions() parses the command line.

2011-05-26format-patch: preserve subject newlines with -kLibravatar Jeff King1-1/+2
In older versions of git, we used rfc822 header folding to indicate that the original subject line had multiple lines in it. But since a1f6baa (format-patch: wrap long header lines, 2011-02-23), we now use header folding whenever there is a long line. This means that "git am" cannot trust header folding as a sign from format-patch that newlines should be preserved. Instead, format-patch needs to signal more explicitly that the newlines are significant. This patch does so by rfc2047-encoding the newlines in the subject line.

2010-04-21revision: --ancestry-pathLibravatar Junio C Hamano1-0/+1
"rev-list A..H" computes the set of commits that are ancestors of H, but excludes the ones that are ancestors of A. This is useful to see what happened to the history leading to H since A, in the sense that "what does H have that did not exist in A" (e.g. when you have a choice to update to H from A). x---x---A---B---C <-- topic / \ x---x---x---o---o---o---o---M---D---E---F---G <-- dev / \ x---o---o---o---o---o---o---o---o---o---o---o---N---H <-- master The result in the above example would be the commits marked with caps letters (except for A itself, of course), and the ones marked with 'o'. When you want to find out what commits in H are contaminated with the bug introduced by A and need fixing, however, you might want to view only the subset of "A..B" that are actually descendants of A, i.e. excluding the ones marked with 'o'. Introduce a new option --ancestry-path to compute this set with "rev-list --ancestry-path A..B". Note that in practice, you would build a fix immediately on top of A and "git branch --contains A" will give the names of branches that you would need to merge the fix into (i.e. topic, dev and master), so this may not be worth paying the extra cost of postprocessing.

2010-03-12Support showing notes from more than one notes treeLibravatar Thomas Rast1-0/+5
With this patch, you can set notes.displayRef to a glob that points at your favourite notes refs, e.g., [notes] displayRef = refs/notes/* Then git-log and friends will show notes from all trees. Thanks to Junio C Hamano for lots of feedback, which greatly influenced the design of the entire series and this commit in particular.

2010-03-09show -c: show patch textLibravatar Junio C Hamano1-0/+1
Traditionally, "show" defaulted to "show --cc" (dense combined patch), but asking for combined patch with "show -c" didn't turn the patch output format on; the placement of this logic in setup_revisions() dates back to cd2bdc5 (Common option parsing for "git log --diff" and friends, 2006-04-14). This unfortunately cannot be done as a trivial change of "if dense combined is asked, default to patch format" done in setup_revisions() to "if any combined is asked, default to patch format", as "diff-tree -c" needs to default to raw, while "diff-tree --cc" needs to default to patch, and they share the codepath. These command specific defaults are now handled in the new "tweak" callback that can be customized by individual command implementations. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2010-03-09revision: introduce setup_revision_optLibravatar Junio C Hamano1-1/+5
So far the last parameter to setup_revisions() was to specify the default ref when the command line did not give any (typically "HEAD"). This changes it to take a pointer to a structure so that we can add other information without touching too many codepaths in later patches. There is no functionality change.
