This uses a normal c array to store parent sha's. That means that we
save a lot of room, as they are only 20 bytes rather than 40 + the cost of
an NSArray and the NSStrings.
We used to use NSObjects, which was really expensive, because for each commit
as many as 100 graphlines can be created. By preallocating them and not
using NSObjects in general, we gain a massive speedup
I'm not sure what this loop originally did, but it was buggy and doesn't
seem logical. Removing it speeds up the graphing a lot, so let's kill it.
We can always get it back later if necessary
This produces cleaner code and is also significantly faster
than the old obj-c code: linux-2.6 goes from ~8 seconds
to ~6 seconds.
Using the c++ code allows us to do easy optimizations
This adds a new target 'SpeedTest', which just loads in a repository
and displays how long it takes to load the revision. This is handy for
testing the speed of the revwalking mechanism
This limits the maximum number of lanes to 32, making the
graphing a lot faster. For example, linux-2.6.git takes only
30 seconds now, rather than >400
This wasn't used anyway. A good idea would be to create a new
branchcontroller that takes care of all these revs, rather than
letting PBGitRepository take care of that
* 'master' of git://github.com/bkerley/gitx:
Use a task (that is properly disposed of) for reading the rev list
make taskForCommand public so other classes can use it
Wait for a child to clear it out.
use outputForCommand instead of handleForCommand to save code, remove zombie-leaking bug
This merges functionality that was previously stored in the
combination of PBGitCommitController / PBChangedFile to a
dedicated controller, PBGitIndexController.
That's why it's there, after all. This also makes the system
more robust and catches some more errors.
The next thing this enables is to also allow right-clicking
on refs in the commit list.
The ref functionality is somewhat weird right now, in that
some parts of the code require a nil array when there are no
refs. So, we add a good removeRef accessor to keep track of this
