--- Comment #6 from Nick Clifton <nickc at redhat dot com> --- (In reply to Frank Ch. Eigler from comment #5) Hi Frank, Yes - I am afraid that the watermark protocol document is a bit out of date, and its rules for note merging do need to be updated. > So, as for a more efficient merging algorithm, I would explore something > like this: Your idea is excellent. However before I go down that route - and probably break building lots of packages by introducing new bugs - would you care to try out a scratch build of the binutils which has a tweaked merge algorithm ? https://koji.fedoraproject.org/koji/taskinfo?taskID=96203568 I just added a variable to keep track of the last non-deleted note, so that the backwards search could start from there, rather than the previous note. With this patch applied I found that merging libxul.so went down from 10.5 minutes to 5 minutes on my local machine. Not an order of magnitude improvement I know, but would it be enough for you ? I am hesitant to rewrite the algorithm entirely because if I get it wrong I am likely to break the building of other packages - either by corrupting the notes so that annocheck then complains, or breaking the merge process so that the rpms do not build or something else.
