Description

Implement submitted changeset posting for Perforce.

This change implements posting for submitted changesets in Perforce. In order
to do this, we fetch the filelog between those revisions, which will give us a
list of every change to every file within those revisions. This is then
processed to accumulate changes together. At the end of this, for each file,
we'll have one of four operations: add, delete, edit, or move. Move operations
can also include edits. This is a little bit complicated to track moves within
the revision range. Just diffing the two trees would handle adds, deletes, and
edits, but not moved files.

Testing Done


Ran unit tests
Posted a variety of revision range changes which included all four of the

  overall change types.

Can we define this on the class so we don't end up building this list every iteration?

david Jan. 6, 2014, 1:57 p.m.

How is it building the list every iteration? The literal isn't re-parsed for each iteration of the loop.

chipx86 Jan. 6, 2014, 7:57 p.m.

Didn't consider that it just treated it as a literal. You're right.

I ran a test to see just what the difference would be, for my own curiosity. I created two scripts with a simple loop doing an if like above, one with the list inline and one pre-defined. It looped it 50 million times, and the literal was faster by 1.4 seconds.

The more you know.

You can use setdefault here instead.

I'm not sure I understand how that would apply in this situation.

changesets.setdefault(cln, {}).set('depot_file', change)
No big deal, just figured it'd save a couple lines.

Given that this function doesn't seem to depend on anything in the parent scope, can we move it into its own proper method on the class? The parent function's pretty large as it is.

rbtools/clients/perforce.py (Diff revision 1)

Do we want to break when we find this, or go for the last one?

I'm hoping we can work toward getting rid of die, since it's not exactly safe when called from anything but an RBTools command. Can we raise exceptions instead?

There was another somewhere else as well that this also applies to.

david Jan. 6, 2014, 1:57 p.m.

I'll fix the one I'm adding but I don't want to make more, unrelated changes right now.

chipx86 Jan. 6, 2014, 7:57 p.m.

Completely fine.

Can we raise an exception here?

david Jan. 6, 2014, 1:57 p.m.

AssertionError? :P

This really is a code consistency check and not really logic. The various tests in the if/elif/else clause are all data that is just used internally.

That said, looking at this, I did forget to handle a few cases :P

chipx86 Jan. 6, 2014, 7:57 p.m.

Sure, that's fine.

Can we bump up to 2.5 for rbtools 0.6? 2.5 is over 7 years old now.
