Hello Joey,
|
|
|
|
I noticed that my Ikiwiki started to rebuild pages very slowly after my last changes
|
|
when I upgraded Ikiwiki to version 3.20100623. Now I have the latest release 3.20100704,
|
|
but it doesn't help me.
|
|
|
|
I started to debug the problem and I found that I can see a lot of messages
|
|
like below when I try to rebuild my wiki manually:
|
|
|
|
svn: '/path/to/ikiwiki/trunk/pages/ostatnie_zmiany' is not a working copy
|
|
svn: Can't open file '/path/to/ikiwiki/trunk/pages/ostatnie_zmiany/.svn/entries': No such file or directory
|
|
svn log exited 256
|
|
|
|
"ostatnie_zmiany" is a value of `recentchangespage` parameter in my
|
|
`ikiwiki.setup` file. It is not under control Subversion I use for Ikiwiki:
|
|
|
|
$ svn status pages/ostatnie_zmiany
|
|
? pages/ostatnie_zmiany
|
|
|
|
$ ls pages/ostatnie_zmiany/*._change |wc -l
|
|
100
|
|
|
|
`recentchangesnum` parameter has value 100 for me and I noticed that my Ikiwiki
|
|
takes a lot of time to parse all `._change` files. Finally it doesn't refresh
|
|
/ostatnie_zmiany.html page.
|
|
|
|
Do you think I should add `ostatnie_zmiany` directory under control of my
|
|
Subversion repo? If it's not necessary, could you please give me any hint
|
|
to find a reason of problem with my Ikiwiki?
|
|
|
|
My best regards,
|
|
Pawel
