Chunking the beast up (patch jockeying) after the fact I can do, but in instances like this... it's not easy to chunk it down into features/tweaks. Basically is big ass blobs of "new stuff", "conversion to new stuff", "remove old stuff". Even with that... still is tricky. Offhand, the existing cache patch could be reduced pretty heavily by breaking it down into addition, and removal of old cache. Obviously after review ability, but also would note the further down you push the required granularity of the patches, the harder it is to have a big picture view of the patchset changes (imo). > > So... guideliness. ? > > Should start a new thread about it later.

It'll mean splitting up the cache patch... Would be curious how it would be chunked up... patch of the new subsystem, patch of portage.py modifications? Depends on def. of logical changes I guess; in the case of the cache patch, it's kind of all or none with the changes. Suggestions/preferences? > I'm not much for the ChangeLog at all really.

No ChangeLog will piss off users; dev's already poke about it on each release. So... guideliness. ? ~harring pgpba6ECTb66O.pgp Description: PGP signature

The cheapness is exactly why I was questioning. Consider: # svn cp tags/2.0.53 branches/2.0.53-branch # cd branches/2.0.53-branch # patch < something-that-needs-fixing-now.patch # svn ci # cd ../.. # svn cp branches/2.0.53-branch tags/2.0.53-r1 # svn rm branches/2.0.53-branch # svn ci compared to: # svn cp tags/2.0.53 tags/2.0.53-r1 # cd tags/2.0.53-r1 # patch < something-that-needs-fixing-now.patch # svn ci With the way subversion works, I would have thought the end result would be identical... > Btw, anyone object to swap branches/2.0 with trunk (seeing that 2.1 is > dead)?

At least not without going over what makes a good commit message and setting up some guidelines. I'm definitely for any ChangeLog being autogenerated though. -- Jason Stubbs -- gentoo-portage-dev@gentoo.org mailing list

The problem is how to guage what is and what is not more trouble than worth. Perhaps adhering to the kernel's rule of "Separate each logical change into its own patch" would help to ease the possible impact of larger changes? Probably the best solution. Speaking of which, if something does crop up with 2.0.53 while the arch guys are deciding if it's stable, how should that be dealt with in subversion? Continue development under branches/2.0 and, should an issue crop up, `svn cp tags/2.0.53_rc6 tags/2.0.53_rc7` and make any required change directly under the tag? Never commit to a tag, make a branch (branches are cheap in svn), and if the branch is finished make a tag. Btw, anyone object to swap branches/2.0 with trunk (seeing that 2.1 is dead)? Another "by the way", `svn -v log > ChangeLog` for 2.0.53_rc6. I'm open to anything better if anybody has a good format for autogeneration. The quality of the commit messages themselves isn't really useful though without knowing their context, so this might be a bit of a catch 22.. For 2.0.54, viewsvn should be available so it might be better to just use the tracker bug to manually create a summary of notable changes. Hmm, so you want to change the ChangeLog into release notes? IMO we should have both (a detailed technical ChangeLog and user friendly release notes). Marius -- gentoo-portage-dev@gentoo.org mailing list
