3 I noticed that my Ikiwiki started to rebuild pages very slowly after my last changes
4 when I upgraded Ikiwiki to version 3.20100623. Now I have the latest release 3.20100704,
5 but it doesn't help me.
7 I started to debug the problem and I found that I can see a lot of messages
8 like below when I try to rebuild my wiki manually:
10 svn: '/path/to/ikiwiki/trunk/pages/ostatnie_zmiany' is not a working copy
11 svn: Can't open file '/path/to/ikiwiki/trunk/pages/ostatnie_zmiany/.svn/entries': No such file or directory
14 "ostatnie_zmiany" is a value of `recentchangespage` parameter in my
15 `ikiwiki.setup` file. It is not under control Subversion I use for Ikiwiki:
17 $ svn status pages/ostatnie_zmiany
18 ? pages/ostatnie_zmiany
20 $ ls pages/ostatnie_zmiany/*._change |wc -l
23 `recentchangesnum` parameter has value 100 for me and I noticed that my Ikiwiki
24 takes a lot of time to parse all `._change` files. Finally it doesn't refresh
25 /ostatnie_zmiany.html page.
27 Do you think I should add `ostatnie_zmiany` directory under control of my
28 Subversion repo? If it's not necessary, could you please give me any hint
29 to find a reason of problem with my Ikiwiki?
