2012-01-19Making pathspec limited log play nicer with --first-parentLibravatar Junio C Hamano1-1/+9
In a topic branch workflow, you often want to find the latest commit that merged a side branch that touched a particular area of the system, so that a new topic branch to work on that area can be forked from that commit. For example, I wanted to find an appropriate fork-point to queue Luke's changes related to git-p4 in contrib/fast-import/. "git log --first-parent" traverses the first-parent chain, and "-m --stat" shows the list of paths touched by commits including merge commits. We could ask the question this way: # What is the latest commit that touched that path? $ git log --first-parent --oneline -m --stat master | sed -e '/^ contrib\/fast-import\/git-p4 /q' | tail The above finds that 8cbfc11 (Merge branch 'pw/p4-view-updates', 2012-01-06) was such a commit. But a more natural way to spell this question is this: $ git log --first-parent --oneline -m --stat -1 master -- \ contrib/fast-import/git-p4 Unfortunately, this does not work. It finds ecb7cf9 (git-p4: rewrite view handling, 2012-01-02). This commit is a part of the merged topic branch and is _not_ on the first-parent path from the 'master': $ git show-branch 8cbfc11 ecb7cf9 ! [8cbfc11] Merge branch 'pw/p4-view-updates' ! [ecb7cf9] git-p4: rewrite view handling -- - [8cbfc11] Merge branch 'pw/p4-view-updates' + [8cbfc11^2] git-p4: view spec documentation ++ [ecb7cf9] git-p4: rewrite view handling The problem is caused by the merge simplification logic when it inspects the merge commit 8cbfc11. In this case, the history leading to the tip of 'master' did not touch git-p4 since 'pw/p4-view-updates' topic forked, and the result of the merge is simply a copy from the tip of the topic branch in the view limited by the given pathspec. The merge simplification logic discards the history on the mainline side of the merge, and pretends as if the sole parent of the merge is its second parent, i.e. the tip of the topic. While this simplification is correct in the general case, it is at least surprising if not outright wrong when the user explicitly asked to show the first-parent history. Here is an attempt to fix this issue, by not allowing us to compare the merge result with anything but the first parent when --first-parent is in effect, to avoid the history traversal veering off to the side branch.

2011-05-11setup_revisions(): take pathspec from command line and --stdin correctlyLibravatar Junio C Hamano1-52/+28
When the command line has "--" disambiguator, we take the remainder of argv[] as "prune_data", but when --stdin is given at the same time, we need to append to the existing prune_data and end up attempting to realloc(3) it. That would not work. Fix it by consistently using append_prune_data() throughout the input processing. Also avoid counting the number of existing paths in the function over and over again.

As v1.6.0-rc2~42 (Allow "non-option" revision options in parse_option-enabled commands, 2008-07-31) explains, options handled by setup_revisions fall into two categories: 1. global options like --topo-order handled by parse_revision_opt, which can take detached arguments and can be parsed in advance; 2. pseudo-options that must be parsed in order with their revision counterparts, like --not and --all. The global options are taken care of by handle_revision_opt; the pseudo-options are currently in a deeply indented portion of setup_revisions. Give them their own function for easier reading. The only goal is to make setup_revisions easier to read straight through. No functional change intended.

2011-03-29revision.c: support --notes command-line optionLibravatar Jeff King1-5/+10
We already have --show-notes, but it has a few shortcomings: 1. Using --show-notes=<ref> implies that we should also show the default notes. Which means you also need to use --no-standard-notes if you want to suppress them. 2. It is negated by --no-notes, which doesn't match. 3. It's too long to type. :) This patch introduces --notes, which behaves exactly like --show-notes, except that using "--notes=<ref>" does not imply showing the default notes.

2011-03-23revision.c: introduce --min-parents and --max-parents optionsLibravatar Michael J Gruber1-7/+21
Introduce --min-parents and --max-parents options which limit the revisions to those commits which have at least (or at most) that many commits, where negative arguments for --max-parents= denote infinity (i.e. no upper limit). In particular: --max-parents=1 is the same as --no-merges; --min-parents=2 is the same as --merges; --max-parents=0 shows only roots; and --min-parents=3 shows only octopus merges Using --min-parents=n and --max-parents=m with n>m gives you what you ask for (i.e. nothing) for obvious reasons, just like when you give --merges (show only merge commits) and --no-merges (show only non-merge commits) at the same time. Also, introduce --no-min-parents and --no-max-parents to do the obvious thing for convenience. We compute the number of parents only when we limit by that, so there is no performance impact when there are no limiters.

2011-03-10git-log: put space after commit markLibravatar Michael J Gruber1-0/+9
Currently, commit marks (left, right, boundary, cherry) are output right before the commit sha1, which makes it difficult to copy sha1s. Sample output for "git log --oneline --cherry": =049c269 t6007: test rev-list --cherry Change this to = 049c269 t6007: test rev-list --cherry which matches exactly the current output of "git log --graph". Leave "git rev-list" output as is (no space) so that they do not break. Adjust "git-svn" which uses "git log --pretty=raw --boundary".

At the porcelain level, because by definition there are many more contributors than integrators, it makes sense to give a handy short-hand for --right-only used with --cherry-mark and --no-merges.

2010-11-23reflogs: clear flags properly in corner caseLibravatar Jeff King1-1/+3
The reflog-walking mechanism is based on the regular revision traversal. We just rewrite the parents of each commit in fake_reflog_parent to point to the commit in the next reflog entry instead of the real parents. However, the regular revision traversal tries not to show the same commit twice, and so sets the SHOWN flag on each commit it shows. In a reflog, however, we may want to see the same commit more than once if it appears in the reflog multiple times (which easily happens, for example, if you do a reset to a prior state). The fake_reflog_parent function takes care of this by clearing flags, including SHOWN. Unfortunately, it does so at the very end of the function, and it is possible to return early from the function if there is no fake parent to set up (e.g., because we are at the very first reflog entry on the branch). In such a case the flag is not cleared, and the entry is skipped by the revision traversal machinery as already shown. You can see this by walking the log of a ref which is set to its very first commit more than once (the test below shows such a situation). In this case the reflog walk will fail to show the entry for the initial creation of the ref. We don't want to simply move the flag-clearing to the top of the function; we want to make sure flags set during the fake-parent installation are also cleared. Instead, let's hoist the flag-clearing out of the fake_reflog_parent function entirely. It's not really about fake parents anyway, and the only caller is the get_revision machinery.

2010-06-02DWIM 'git show -5' to 'git show --do-walk -5'Libravatar Jonathan Nieder1-0/+4
To show the last two commits with one command, one might try 1) git show -s master~2.. 2) git show -s ^master~2 master 3) git show -s master^ master 4) git show -s -2 master Choice (3) works because both commits are listed on the command line. Choices (1) and (2) have worked ever since v1.6.4-rc~3 (Make 'git show' more useful, 2009-07-13) disabled --no-walk in this case because there is no other useful meaning for them to have. Unfortunately, (4) does not work: it outputs only one commit, because --no-walk stays on. So disable --no-walk in this case so ‘git show’ and future ‘git cherry-pick’ can behave as expected. As a side effect, this unfortunately changes the meaning of ‘git log --oneline --decorate --no-walk -5 --all’: instead of listing five refs, after this patch that command would list the five most recent commits.

Without this patch at least IBM VisualAge C 5.0 (I have 5.0.2) on AIX 5.1 fails to compile git. enum style is inconsistent already, with some enums declared on one line, some over 3 lines with the enum values all on the middle line, sometimes with 1 enum value per line... and independently of that the trailing comma is sometimes present and other times absent, often mixing with/without trailing comma styles in a single file, and sometimes in consecutive enum declarations. Clearly, omitting the comma is the more portable style, and this patch changes all enum declarations to use the portable omitted dangling comma style consistently. Signed-off-by: Gary V.
