[zypp-devel] Getting rid of boost::regex !?
Coolo asked whether we can get rid of libboost_regex, as it requires to much memory in the instsys (not libboost_regex but the libraries it requires). As far as I see it will affect: KeyRing Edition Applydeltarpm RpmDb Url / UrlBase CapabilityImpl PublicKey MediaSetAccess plaindir/RepoParser This is pretty vital stuff.

I don't think this is a good idea for 10.3. Stano -- To unsubscribe, e-mail: zypp-devel+unsubscribe@opensuse.org For additional commands, e-mail: zypp-devel+help@opensuse.org

Dirk has a patch against our tree with most of the work done. He knows the patch is not ready because some tests fails. But once they pass? Duncan -- To unsubscribe, e-mail: zypp-devel+unsubscribe@opensuse.org For additional commands, e-mail: zypp-devel+help@opensuse.org

Don't we have enough problems? Check your bugzilla... (I hope this is not there yet ;-) Stano -- To unsubscribe, e-mail: zypp-devel+unsubscribe@opensuse.org For additional commands, e-mail: zypp-devel+help@opensuse.org

I have mixed feelings. Certainly 1.5 mb is a lot for a library. Searching google for "boost regex" gives you boost documentatio, while "glibc regex" gives you a full page of bugs, concurrency issues and problems. Also, anyone has performance data?

For replacing: - glibc is smaller - glibc might be faster (but I have not benchmarked. And anyway, if speed matters, we should optimize regexes away completely. Like in CapabilityImpl::parse [*]) Against replacing: - it is not a regression compared to 10.1 or 10.2 - using a different regex engine might cause bugs because of slightly different regex dialects. My conclusion is not to change it for 10.3 [*] http://mailman.suse.de/mlarch//SuSE/zypp-devel/2006/zypp-devel.2006.05/msg00...
For update-status the situation is quite clear. The time is totally dominated by the Boost regex machinery for parsing the capabilities and by the uniquifying of the Capabilities. For the former I already made some suggestions on #zypp which Michael Andres might have already implemented,
