Of cause if diff contains only ascii, it can be used safely

Should I remove my sign with Cyrillic UTF-8 chars from messages with patches then? -- Roman Kyrylych (Роман Кирилич)

Naw, as long as it's not in the diff - and even then it would still work just won't DISPLAY right. diff's are bounded. It has a beginning "+++ ---" and then it says "use the next Y lines". You can have as much garbage as you want above and below them. This was done intentionally, so that diffs could be included directly in emails.

OK, so I will include short diffs right into the message and long and complex compress with gzip. Right? [offtopic on] BTW, about complex patches - I have a patch from Martin Devera that adds support for gdbm database backend to pacman 2.9.8. I suggested him to contact VMiklos for help in inclusion it in pacman, but I don't know if he did that. If I adapt it for Pacman 3 API is there a chance it will be included at least in CVS/DARCS?

There's no chance that would get included in pacman 2.9.8 - it will die soon.

Converting it to pacman3 is entirely doable and it's already setup to do so. You should be able to copy be_files.c to be_gdbm.c and consume the interface provided there.

FTR 'be_' means 'backend'. I still need to add compile-time flags for selecting a backend, but as we only provide _files at the moment, there's no need.

I worked on a 'compressed' backend that required no changes, but read directly from the downloaded db files... it caused problems on the local db, however, so I never completed it (yet).

As for backend schemes, I think we need to discuss avenues of attack here. The files backend is painfully slow on ext filesystems (11 seconds to parse [community]). There are many users touting a database backend as a good idea (I highly disagree), and if we do this, we NEED a generic layer to support any sane database format, not just one specific thing. Using a flat-file database is a better option, but here people seem to think sqlite is a good idea (it's not) - there are many flat-file schemes that can drastically outperform sqlite.

There are many many other options, and I think it's worth at least _supplying_ multiple backends, even if they're not used. So gdbm is cool.

Maybe we should start separate thread for this? Personally, I think sqlite will be the best choice because of: 1) it's small 2) it's fast 3) it's embedable 4) it offers full power of SQL99 (with ACID transactions!!!) 5) it's public domain! :-D -- Roman Kyrylych (Роман Кирилич)

no, he never did so

The patch was originally submitted here: http://bugs.archlinux.org/task/5328 I want to try to adapt it for pacman3 API, but you are more experienced so you may do this faster, if you have time and wish. ;-) -- Roman Kyrylych (Роман Кирилич)

thanks for the link. anyway i'm totally unfamiliar with gdbm + krix prefers sqlite, so.. we'll see

I agree with krix. :-p Anyway I'll try to adapt gdbm, even if someone's work will be better. This will help me to learn pacman internals. -- Roman Kyrylych (Роман Кирилич)
