doc/bugs/A_page_that_inlines_pages__61____34____42____34___results_in_unnecessary_feed_generation.mdwn

   1 I noticed when generating my wiki that all of my RSS feeds were
   2 getting regenerated even when I edited only a page that did not affect
   3 any feed.
   4
   5 I found that the problem only occurs in the presence of a file that
   6 contains \[[inline pages="*"]].
   7
   8 Here's a short script for replicating the bug. Just cut and paste this
   9 to a shell, (it will only muck in a new /tmp/ikiwiki-test directory
  10 that it will create):
  11
  12         cd /tmp
  13         mkdir ikiwiki-test; cd ikiwiki-test; mkdir src
  14         echo '[[inline pages="blog/*"]]' > src/myblog.mdwn
  15         mkdir src/blog; echo "A blog entry" > src/blog/entry.mdwn
  16         echo 'use IkiWiki::Setup::Standard {
  17                 srcdir => "src",
  18                 destdir => "output",
  19                 url => "http://example.com",
  20                 templatedir => "/dev/null",
  21                 underlaydir => "/dev/null",
  22                 rss => 1,
  23                 wrappers => [],
  24                 verbose => 1,
  25                 refresh => 1
  26         }' > setup
  27         ikiwiki --setup setup
  28         ls -l --time-style=full-iso output/myblog/index.rss
  29         echo "not a blog entry" > src/not-a-blog.mdwn
  30         ikiwiki --setup setup
  31         ls -l --time-style=full-iso output/myblog/index.rss
  32         echo '[[inline pages="*"]]' > src/archives.mdwn
  33         ikiwiki --setup setup
  34         ls -l --time-style=full-iso output/myblog/index.rss
  35         echo "still not blogging" >> src/not-a-blog.mdwn
  36         ikiwiki --setup setup
  37         ls -l --time-style=full-iso output/myblog/index.rss
  38
  39 Here's the tail of the output that I see for this command:
  40
  41         $ echo "not a blog entry" > src/not-a-blog.mdwn
  42         $ ikiwiki --setup setup
  43         refreshing wiki..
  44         scanning not-a-blog.mdwn
  45         rendering not-a-blog.mdwn
  46         done
  47         $ ls -l --time-style=full-iso output/myblog/index.rss
  48         -rw-r--r-- 1 cworth cworth 459 2007-06-01 06:34:36.000000000 -0700 output/myblog/index.rss
  49         $ echo '[[inline pages="*"]]' > src/archives.mdwn
  50         $ ikiwiki --setup setup
  51         refreshing wiki..
  52         scanning archives.mdwn
  53         rendering archives.mdwn
  54         done
  55         $ ls -l --time-style=full-iso output/myblog/index.rss
  56         -rw-r--r-- 1 cworth cworth 459 2007-06-01 06:34:37.000000000 -0700 output/myblog/index.rss
  57         $ echo "still not blogging" >> src/not-a-blog.mdwn
  58         $ ikiwiki --setup setup
  59         refreshing wiki..
  60         scanning not-a-blog.mdwn
  61         rendering not-a-blog.mdwn
  62         rendering archives.mdwn, which depends on not-a-blog
  63         done
  64         $ ls -l --time-style=full-iso output/myblog/index.rss
  65         -rw-r--r-- 1 cworth cworth 459 2007-06-01 06:34:38.000000000 -0700 output/myblog/index.rss
  66
  67 It looks like the rendering of archives.mdwn is also silently
  68 generating myblog/index.rss.
