I haven't tested it, but a restore from backup might be enough to confuse doc-base's ctime tracking.

It will only be significant for people who have install/upgrade lots of doc-files at a time. I expect most people with lots of doc-files either have doc-linux-html installed (64.1MB, 393 doc-base files, 85 min to index), doc-linux-nonfree-html installed (9961kB, 64 files, 16 mins) or lots of doc packages. (doc-linux-text and doc-linux-nonfree-text don't seem to have any doc-base files). I actually think that the best work-around for Lenny would be Esteban Manchado Velázquez's suggestion in bug 497139 of *not* reindexing documentation (just register the documents) when doc-base calls dhelp with more than, say, 20 files. (There is a cron.weekly job that should rebuild the index). That will hopefully prevent delays longer than about five minutes for each dpkg run, and yet still result in most packages being indexed during installation. Another alternative might be to stop using triggers for doc-base. (I don't really understand the gains from registering/indexing multiple packages all at once, as compared to one index run per package. Then the only long delay would be doc-linux-html, and people should expect that to take a while to index). <snip> In another email Ross Boylan wrote > I just did another upgrade (within testing) that took about 2 hours > because of this problem. I'm guessing that would have been the recent update of doc-linux to 2008.08-1? HTH Andrew -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
