18 years agorev-list: stop when the file disappears
Linus Torvalds [Wed, 18 Jan 2006 22:47:30 +0000 (14:47 -0800)]
rev-list: stop when the file disappears

The one thing I've considered doing (I really should) is to add a "stop
when you don't find the file" option to "git-rev-list". This patch does
some of the work towards that: it removes the "parent" thing when the
file disappears, so a "git annotate" could do do something like

git-rev-list --remove-empty --parents HEAD -- "$filename"

and it would get a good graph that stops when the filename disappears
(it's not perfect though: it won't remove all the unintersting commits).

It also simplifies the logic of finding tree differences a bit, at the
cost of making it a tad less efficient.

The old logic was two-phase: it would first simplify _only_ merges tree as
it traversed the tree, and then simplify the linear parts of the remainder
independently. That was pretty optimal from an efficiency standpoint
because it avoids doing any comparisons that we can see are unnecessary,
but it made it much harder to understand than it really needed to be.

The new logic is a lot more straightforward, and compares the trees as it
traverses the graph (ie everything is a single phase). That makes it much
easier to stop graph traversal at any point where a file disappears.

As an example, let's say that you have a git repository that has had a
file called "A" some time in the past. That file gets renamed to B, and
then gets renamed back again to A. The old "git-rev-list" would show two
commits: the commit that renames B to A (because it changes A) _and_ as
its parent the commit that renames A to B (because it changes A).

With the new --remove-empty flag, git-rev-list will show just the commit
that renames B to A as the "root" commit, and stop traversal there
(because that's what you want for "annotate" - you want to stop there, and
for every "root" commit you then separately see if it really is a new
file, or if the paths history disappeared because it was renamed from some
other file).

With this patch, you should be able to basically do a "poor mans 'git
annotate'" with a fairly simple loop:

push("HEAD", "$filename")
while (revision,filename = pop()) {
for each i in $(git-rev-list --parents --remove-empty $revision -- "$filename")

pseudo-parents($i) = git-rev-list parents for that line

if (pseudo-parents($i) is non-empty) {
show diff of $i against pseudo-parents
continue
}

/* See if the _real_ parents of $i had a rename */
parent($i) = real-parent($i)
if (find-rename in $parent($i)->$i)
push $parent($i), "old-name"

    ++ static void describe(char *arg, int last_one)
       {
     +      unsigned char sha1[20];
     +      struct commit *cmit;

There are a few things to note about this feature:

 - The '-c' option implies '-p'.  It also implies '-m' halfway
   in the sense that "interesting" merges are shown, but not all
   merges.

 - When a blob matches one of the parents, we do not show a diff
   for that path at all.  For a merge commit, this option shows
   paths with real file-level merge (aka "interesting things").

 - As a concequence of the above, an "uninteresting" merge is
   not shown at all.  You can use '-m' in addition to '-c' to
   show the commit log for such a merge, but there will be no
   combined diff output.

 - Unlike "gitk", the output is monochrome.

A '-' character in the nth column means the line is from the nth
parent and does not appear in the merge result (i.e. removed
from that parent's version).

A '+' character in the nth column means the line appears in the
merge result, and the nth parent does not have that line
(i.e. added by the merge itself or inherited from another
parent).

The above example output shows that the function signature was
changed from either parents (hence two "-" lines and a "++"
line), and "unsigned char sha1[20]", prefixed by a " +", was
inherited from the first parent.

The code as sent to the list was buggy in few corner cases,
which I have fixed since then.

It does not bother to keep track of and show the line numbers
from parent commits, which it probably should.
