Agreed. But there were some other pending changes for "VERSION: 1" Any planned changes to the format should be documented on https://bugs.gentoo.org/show_bug.cgi?id=263994 > 2) a header alone isn't useful unless it's specifiable per cpv entry; > thus it must be inheritable Per CPV entries is going to bloat the format and make me carry around a more data on a per pkg basis then I'd want to. How about we run with zac's idea but use tools to convert a full repo over to $EXTENTION This should keep the portage code fast as well as it checks for invalid binpkgs all the time. Having to have portage process a ton of ever growing extentions is just going to be slow. > 3) PACKAGE_EXTENSION is overly verbose and unclear it's specifying > the compressor too; it's intention is for compression, state it as > such (I mention this in light of URI's existance where > PACKAGE_EXTENSION would only be a hint of compressor) > > Re: #1, there is a decent set of optimizations I'm kicking around in > pkgcore for the next version- a discussion should probably be started > there. > > Offhand, having a compression specific header (a simple enumeration > of known compressors) and a DEFAULT_URI that is python string No go bro.
