[Monotone-devel] cvsimport branch reconstruction status

[Markus Schiltknecht]

Hi,

as you may know, I'm trying to implement the cvs2svn 2.0 algorithm 
inside monotones cvs_import command. I've made quite some progress 
recently, and just yesterday, my two test cases checking for correct 
branching succeeded.

It's still experimental code, though. I have not implemented splitting 
of blobs nor tags, so other test cases fail. But switching to using 
blobs of cvs events has been done. Now, during parsing of the RCS files, 
all cvs events are collected in blobs, depending only on the author / 
changelog information.

Then the blobs dependencies are checked. As I did not implement 
splitting blobs, the import just fails in case of circular deps.

Finally, the boost graph topological sort algorithm is invoked to feed 
the blobs in the correct order to the cluster_consumer, which could more 
or less be used as is from the current code.

As I'm not that experienced with C++ I would really appreciate some 
guidance WRT style and coding conventions. I'm still missing the ease of 
use of the foot-gun I would call 'C pointers', for example.

Another note: I've decided to use boost graph's topological sort before 
noting that monotone coded it's own graph stuff. Is it a bad idea to 
link to boost graph?

Regards

Markus
