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"
}

which should be doable in perl or something (doing stacks in shell is just
too painful to be worth it, so I'm not going to do this).

Anybody want to try?

18 years agogit-push: avoid falling back on pushing "matching" refs.
Junio C Hamano [Thu, 12 Jan 2006 23:29:12 +0000 (15:29 -0800)]
git-push: avoid falling back on pushing "matching" refs.

The underlying "git send-pack remote.host:path" pushes all the
matching refs that both local and remote have, and "git push"
blindly inherits this property.  Which probably was a mistake.

A typical cloned repository (e.g. a subsystem repository cloned
from Linus repository) has at least two branches, "master" to
keep the subsystem and "origin" that records tip of Linus
"master" when the repository was cloned.  If this is the public
repository for the subsystem, then subsystem developers would
clone it, and then cloned ones have "master" and "origin".  When
developers use this public subsystem repository as a shared
repository, pushing into it via "git push subsys:/path/name"
would try to push the matching refs, "master" and "origin", from
the developers' repositories.  The "origin" in the public shared
repository does not have much relevance, yet pushing into
"origin" would cause "not a fast forward" checks to be
triggered.  Arguably "git push subsys:/path/name master" would
work it around, but having them to say it explicitly to avoid
pushing into "origin" as well is bad.

This commit requires you to give at least one refspec to
git-push.  You could "give" by either:

 (1) Listing the refspec(s) explicitly on the command line.
     E.g. "git push subsys:/path/name master".

 (2) Using --all or --tags on the command line.
     E.g. "git push --tags subsys:/path/name".

 (3) Using a $GIT_DIR/remotes shorthand with 'Push: refspec'
     line in it.

Unlike pull that can happen pretty much promiscuously, people
will push into the same set of a limited number of remote
repositories repeatedly over the life of the project, so it is
reasonable to assume they would want to keep a $GIT_DIR/remotes/
entry for those repositories even only to save typing the URL,
so keeping the default 'Push: refspec' line in such is a
sensible thing to do.

It was suggested to further fall back on pushing the current
branch, but this commit does not implement it.  If developers
adopt topic branch workflow, pushing to public while on a topic
branch by mistake would expose the topic branch to the public
repository.  Not falling back to the current branch prevents
that mistake from happening.

- git wrapper will modify PATH as before to enable shell scripts to
  invoke "git-foo" commands.

Ideally, shell scripts should use the git wrapper to become independent
of PATH, and then modifying PATH will not be necessary.

octopus: allow criss-cross and clarify the message when it rejects

We rejected multi-base merge situations even though we used the
same underlying multi-base git-read-tree as the resolve strategy
uses.  This was unneeded and did not add much to ensure the
merge to be truly trivial, so remove this restriction and be
more similar to what resolve does.

Also when the merge did not trivially resolve, we rejected
without stating that octopus strategy does not handle the
situation.
