CVS is not a really wonderful source control system.
It is our plan to convert to Mercurial some time in the reasonably near
future. Reviews of it have been mostly very good.
We will still be able to have a source control mailing list, and a web
interface. From what I can see both will be nicer than at present.
But, it will mean people grabbing versions of the code will need to have
a copy of Mercurial.
(Just back from two-week holiday, so playing catch-up...)
Agreed that CVS has been been improved upon by other offerings.
But any reason for choosing mercurial, rather than subversion (svn) as the
next-generation source control management system? (GNU seem to use SVN;
samba has recently switched to SVN; etc.) What are the pros/cons of
mercurial vs. svn?
(I know almost nothing of either! But for us Linux-HA maintainers, this
change could be high-impact, so it seems worth checking that we are
jumping in the best direction...)
As a Solaris guy, you might want to know that Sun has standardized on
Mercurial for OpenSolaris ;-).
But, Mercurial supports multiple repositories, with the ability to merge
patches, push and pull patches between them. It directly supports
change sets, is very fast, and seems to be the the most sophisticated of
the current source control offerings - with the possible exception of
git. Unlike git, the command set is fairly CVS-like. All updates are
transactional - either the whole change set is committed, or none of it
- regardless of network problems, or crashes.
Mercurial's on-disk data structures seem to be done really right. To
extract a version containing 'n' bytes, they'll never have to read more
2*n bytes off disk - no matter what the history.
Repository files are only appended to - never modified or replaced. So,
even with bugs in the code or running out of disk space, they should
never damage old versions of the code.
