i'm torn on this question, for a host of reasons:
pros for making the DRUPAL-5 branch early:
a) we have documented, expected conventions and practices to follow,
and being consistent is good. consistency with core is also good.
b) if they don't create a DRUPAL-5 branch *before* they start adding
new features, people who don't really understand or have real
experience with branch management (98% of the people reading this
message, it seems) are more likely to screw things up and get in a
situation where if there's a security problem in an older release,
they have no way to release a new version that only fixes the bugs,
and doesn't introduce new features which might break live sites.
c) people looking at Drupal via CVS will know what's going on.
otherwise, they're stuck with HEAD, which could be anything, and
they'd have to go look at the project node (and read through
everything on the "All releases" page) to figure out what's really
going on in HEAD.
cons for making the DRUPAL-5 branch early:
a) it will generate more work, since you have another branch to
commit fixes to. i won't pass judgement on how much more work, since
b) so long as you tagged your DRUPAL-5--1-0 stable release (on HEAD),
you could delay creating a DRUPAL-5 branch until you actually needed
it (e.g. security problem or bugs you need to fix) while still
developing new features directly in HEAD .
c) the straight-from-CVS crowd is a minority and can probably be
expected to know more than nothing. making more work for the
maintainers to make life easier for the people just browsing via CVS
is not a clear win IMHO. so long as everything is reasonable and
sane with official releases on the module browsing pages and the
project node, i'm a little less concerned about how things look in
so, there are good reasons for doing it both ways. however, all of
the good reasons for delaying the branch assume a *very* clueful
maintainer who is careful about not screwing themselves (really,
their users) badly in case they need to release a security update...
bottom line: i'm getting incredibly burnt out being everyone's free
revision control consultant/tutor (and no, craig, that's not directed
at you, or anyone in particular, so no one should take this
personally). if i had faith that people would read, understand, and
correctly follow the instructions and conventions for handling
various situations, i'd be able to suggest using some more advanced
approaches to revision management to solve many of these problems.
but, every time i try to unlock another door to people's revision
control understanding, i get buried in a new avalanche of email/
issues/IRC questions about it. i've been trying to build tools for
and document/teach practices that will tend to have people get things
right, but i can't single-handedly train the entire drupal community
on everything about branches, release management, development
snapshots vs. official releases, why you can't commit changes to a
therefore, if you're a power CVS user, and you know exactly what
you're doing, and you promise never to ask me to bail you out when
you screw something up, do whatever you think is best. if *any* of
those conditions are *not* met, do what i wrote in the handbooks
(make the branch as soon as your 5.x code is stable and you're ready
for a 5.x-1.0 release).
 if you don't already know how to do this, don't try it, and don't
bother asking. if i wrote a handbook page about it, people would
expect me to provide unlimited support for it. that's the same
reason i refuse to write a handbook page about merging branches. if
you can figure it out on your own, you don't need my help. if you
can't, i'm not going to hand you a loaded gun and say "good luck, try
not to hurt anyone", especially given the apparently high failure
rate of people reading and understanding the CVS docs i've already
p.s. if anyone dares to suggest that "SVN would be easier", i'll find
a way to have your legs broken. NONE of these problems have ANYTHING
to do with CVS vs. SVN tool syntax. it's all about people not
understanding fundamental concepts of revision control and release
management, which is totally independent of the tool we happen to be
using. you've been warned...
