Man selection has to be performed over several thousand rows in some cases. Loading all those in Perl and then doing the selection isn't very efficient[1]. The getman() implementation was also buggy: The comparison function used to determine which man page should be preferred was not associative[2], and the result thus depended on the order in which the man pages were compared. This resulted in some wrong selections in some cases. While I was at it, I also made the selection more strict: - /man/unknown-hash would previously ignore the hash and just select whatever man page. Now it results in a 404. - Same with /man.unknown-section - /man.section/hash is now disallowed, it's either /man.section or /man/hash. 1) Note that all possible man pages are currently still loaded into Perl anyway, because the ugly navigation menu on the right needs them. I plan to revamp that entire menu to be more efficient and usable. 2) Initially I wrote the SQL implementation in a similar fashion to the Perl implementation, and ended up with the same bug. I wasted more than a day before I finally got to the current CTE query. |
