* Merge branch 'as/maint-graph-interesting-fix'Junio C Hamano2009-08-271-2/+3
|\ | | | | | | | | | | * as/maint-graph-interesting-fix: Add tests for rev-list --graph with options that simplify history graph API: fix bug in graph_is_interesting()
| * graph API: fix bug in graph_is_interesting()Adam Simpkins2009-08-211-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, graph_is_interesting() did not behave quite the same way as the code in get_revision(). As a result, it would sometimes think commits were uninteresting, even though get_revision() would return them. This resulted in incorrect lines in the graph output. This change creates a get_commit_action() function, which graph_is_interesting() and simplify_commit() both now use to determine if a commit will be shown. It is identical to the old simplify_commit() behavior, except that it never calls rewrite_parents(). This problem was reported by Santi BĂ©jar. The following command would exhibit the problem before, but now works correctly: git log --graph --simplify-by-decoration --oneline v1.6.3.3 Previously git graph did not display the output for this command correctly between f29ac4f and 66996ec, among other places.

* | graph API: use a new color when starting a brand new columnAdam Simpkins2009-08-181-3/+11
|/ | | | | | | | | | | | | Use a new color for commits that don't have any previously printed children. The following command demonstrates the changes: git log --graph --pretty=tformat:'%h %s%n' -7 481c7a6 18b0793 Now the two independent lines of development are displayed with different colors, instead of both using the same color.

* Replace calls to strbuf_init(&foo, 0) with STRBUF_INIT initializerBrandon Casey2008-10-121-9/+4
| | | | | | | | | | | Many call sites use strbuf_init(&foo, 0) to initialize local strbuf variable "foo" which has not been accessed since its declaration. These can be replaced with a static initialization using the STRBUF_INIT macro which is just as readable, saves a function call, and takes up fewer lines.

* git log --graph: print '*' for all commits, including mergesAdam Simpkins2008-06-061-14/+0
| | | | | | | | | | | | Previously, merge commits were printed with 'M' instead of '*'. This had the potential to confuse users when not all parents of the merge commit were included in the log output. As Junio has pointed out, merge commits can almost always be easily identified from the log message, anyway.

* graph API: fix "git log --graph --first-parent"Adam Simpkins2008-06-061-11/+53
| | | | | | | | | | | | | | | | This change teaches the graph API that only the first parent of each commit is interesting when "--first-parent" was specified. This change also consolidates the graph parent walking logic into two new internal functions, first_interesting_parent() and next_interesting_parent(). A simpler fix would have been to simply break at the end of the 2 existing for loops when graph->revs->first_parent_only is set. However, this change seems nicer, especially if we ever need to add any new loops over the parent list in the future.

* graph API: avoid printing unnecessary padding before some octopus mergesAdam Simpkins2008-06-011-5/+8
| | | | | | | | | | | | | | | | | | | | | When an octopus merge is printed, several lines are printed before it to move over existing branch lines to its right. This is needed to make room for the children of the octopus merge. For example: | | | | | | \ \ | | \ \ | | \ \ | M---. \ \ | |\ \ \ \ \ However, this step isn't necessary if there are no branch lines to the right of the octopus merge. Therefore, skip this step when it is not needed, to avoid printing extra lines that don't really serve any purpose.

Previously, merge commits were displayed as: | M \ | |\ | As pointed out by Teemu Likonen, this didn't look nice if the rightmost branch line was displayed as '\' on the previous line, as it then appeared to have an extra space in it: | |\ | M \ | |\ | This change updates the code so that branch lines to the right of merge commits are printed slightly differently depending on how the previous line was displayed: | |\ | | | | | / | M \ | M | | M | | |\ \ | |\ \ | |\ \ Signed-off-by: Adam Simpkins <adam@adamsimpkins.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* get_revision(): honor the topo_order flag for boundary commitsAdam Simpkins2008-05-251-8/+1
| | | | | | | | | Now get_revision() sorts the boundary commits when topo_order is set. Since sort_in_topological_order() takes a struct commit_list, it first places the boundary commits into revs->commits.

* Fix output of "git log --graph --boundary"Adam Simpkins2008-05-251-13/+66
| | | | | | | | | | | | | | | | Previously the graphing API wasn't aware of the revs->boundary flag, and it always assumed that commits marked UNINTERESTING would not be displayed. As a result, the boundary commits were printed at the end of the log output, but they didn't have any branch lines connecting them to their children in the graph. There was also another bug in the get_revision() code that caused graph_update() to be called twice on the first boundary commit. This caused the graph API to think that a commit had been skipped, and print a "..." line in the output.

* log --graph --left-right: show left/right information in place of '*'Adam Simpkins2008-05-251-11/+11
| | | | | | | | | | | | | | | | | With the --graph option, the graph already outputs 'o' instead of '*' for boundary commits. Make it emit '<' or '>' when --left-right is specified. (This change also disables the '^' prefix for UNINTERESTING commits. The graph code currently doesn't print anything special for these commits, since it assumes no UNINTERESTING, non-BOUNDARY commits are displayed. This is potentially a bug if UNINTERESTING non-BOUNDARY commits can actually be displayed via some code path.)

* graph API: don't print branch lines for uninteresting merge parentsAdam Simpkins2008-05-251-13/+44
| | | | | | | | | | | | | | | | | | | | | Previously, the graphing code printed lines coming out of a merge commit for all of its parents, even if some of them were uninteresting. Now it only prints lines for interesting commits. For example, for a merge commit where only the first parent is interesting, the code now prints: * merge commit * interesting child instead of: M merge commit |\ * interesting child Signed-off-by: Adam Simpkins <adam@adamsimpkins.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* graph API: fix graph mis-alignment after uninteresting commitsAdam Simpkins2008-05-251-0/+3
| | | | | | | | | | | | | | | | | | | | | | The graphing code had a bug that caused it to output branch lines incorrectly after ignoring an uninteresting commit. When computing how to match up the branch lines from the current commit to the next one, it forgot to take into account that it needed to initially start with 2 empty spaces where the missing commit would have gone. So, instead of drawing this, | * | <- Commit with uninteresting parent | / * | It used to incorrectly draw this: | * | <- Commit with uninteresting parent * | Signed-off-by: Adam Simpkins <adam@adamsimpkins.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* graph API: eliminate unnecessary indentationAdam Simpkins2008-05-051-14/+52
| | | | | | | | | | This change improves the calculation of the amount of horizontal padding, so that there is always exactly 1 space of padding.
