Description Robin Green 2016-02-23 15:12:09 EST
Description of problem:
M-x man does not complete man pages that have recently been installed. However, it displays them just fine.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. sudo dnf install autofs
2. In emacs, M-x man
3. auto <TAB>

Actual results:
Possible completions are:
AutoLoader(3pm) 	AutoSplit(3pm)
autoconf(1) 	autodie(3pm)
autodie::Scope::Guard(3pm) 	autodie::Scope::GuardStack(3pm)
autodie::Util(3pm) 	autodie::exception(3pm)
autodie::exception::system(3pm) 	autodie::hints(3pm)
autodie::skip(3pm) 	autoheader(1)
autom4te(1) 	automake(1)
automake-1.15(1) 	autopoint(1)
autoreconf(1) 	autoscan(1)
autoupdate(1) 	autouse(3pm)

Expected results:
Should include autofs(8) and autofs.conf(5). It is not about the section, because resolv.conf(5) _is_ completed correctly.
Comment 1 Robin Green 2016-02-23 15:13:49 EST
Maybe this is actually a bug in the autofs rpm spec file - maybe it should ensure the man page "cache" that is evidently being used here (whatever it is) is updated?
Comment 2 Jan Synacek 2016-03-08 05:36:05 EST
Probably not, since spec files usually don't invoke mandb directly. Running mandb after installing the package solves the issue.

I don't know how rpm uses the man cache when it installs packages containing man pages. Could anybody from the rpm team please advise?
Comment 3 Jan Chaloupka 2016-03-08 06:03:45 EST
The cache is maintained by man-db.
Comment 4 Colin Watson 2016-03-08 06:43:16 EST
This is supposed to be handled by the %transfiletriggerin (etc.) trigger in man-db's spec file.  That's probably the place to start looking.
Comment 5 Nikola Forró 2016-03-08 06:45:50 EST
In F23, the man cache is updated daily by a cron job. In F24, starting with version 2.7.3-2.fc24, man-db takes advantage of new rpm feature called file triggers and man cache update is triggered after installation of any package containing man pages.
Since rpm in F23 also supports file triggers, I will rebase man-db in F23 to solve this issue.
