2pc_xlog.diff (application/octet-stream) patch
(unnamed) (text/plain)

Hi.

I’ve updated patch and wrote description of thighs that happens
with 2PC state data in the beginning of the file. I think now this patch is well documented,
but if somebody points me to places that probably requires more detailed description I’m ready
to extend that.
