+Language display order
+----------------------
+
+Jonas pointed out that one might want to control the order that links to
+other languages are listed, for various reasons. Currently, there is no
+order, as `po_slave_languages` is a hash. It would need to be converted
+to an array to support this. (If twere done, twere best done quickly.)

+
+Pagespecs
+---------
+
+I was suprised that, when using the map directive, a pagespec of "*"
+listed all the translated pages as well as regular pages. That can 
+make a big difference to an existing wiki when po is turned on,
+and seems generally not wanted.
+(OTOH, you do want to match translated pages by
+default when locking pages.) --[[Joey]]
+
+Edit links on untranslated pages
+--------------------------------

 
 

-Robustness tests
-----------------
+If a page is not translated yet, the "translated" version of it
+displays wikilinks to other, existing (but not yet translated?)
+pages as edit links, as if those pages do not exist. 

 
 

-### Enabling/disabling the plugin
+That's really confusing, especially as clicking such a link
+brings up an edit form to create a new, english page.

 
 

-* enabling the plugin with `po_translatable_pages` set to blacklist: **OK**
-* enabling the plugin with `po_translatable_pages` set to whitelist: **OK**
-* enabling the plugin without `po_translatable_pages` set: **OK**
-* disabling the plugin: **OK**
+This is with po_link_to=current or negotiated. With default, it doesn't
+happen.. 

 
 

-### Changing the plugin config
+Also, this may only happen if the page being linked to is coming from an
+underlay, and the underlays lack translation to a given language.
+--[[Joey]] 

 
 

-* adding existing pages to `po_translatable_pages`: **OK**
-* removing existing pages from `po_translatable_pages`: **OK**
-* adding a language to `po_slave_languages`: **OK**
-* removing a language from `po_slave_languages`: **OK**
-* changing `po_master_language`: **OK**
-* replacing `po_master_language` with a language previously part of
-  `po_slave_languages`: needs two rebuilds, but **OK** (this is quite
-  a perverse test actually)
+> Any simple testcase to reproduce it, please? I've never seen this
+> happen yet. --[[intrigeri]]

 
 

-### Creating/deleting/renaming pages
+>> Sure, go here <http://l10n.ikiwiki.info/smiley/smileys/index.sv.html>
+>> (Currently 0% translateed) and see the 'WikiLink' link at the bottom,
+>> which goes to <http://l10n.ikiwiki.info/ikiwiki.cgi?page=ikiwiki/wikilink&from=smiley/smileys&do=create>
+>> Compare with eg, the 100% translated Dansk version, where
+>> the WikiLink link links to the English WikiLink page. --[[Joey]] 

 
 

-All cases of master/slave page creation/deletion/rename, both via RCS
-and via CGI, have been tested.
+Double commits of po files
+--------------------------
+
+When adding a new english page, the po files are created, committed,
+and then committed again. The second commit makes this change:
+
+       -"Content-Type: text/plain; charset=utf-8\n"
+       -"Content-Transfer-Encoding: ENCODING"
+       +"Content-Type: text/plain; charset=UTF-8\n"
+       +"Content-Transfer-Encoding: ENCODING\n"
+
+Same thing happens when a change to an existing page triggers a po file
+update. --[[Joey]] 
+
+> * The s/utf-8/UTF-8 part is fixed in my po branch.
+> * The ENCODING\n part is due to an inconsistency in po4a, which
+>   I've just send a patch for. --[[intrigeri]]
+
+Ugly messages with empty files
+------------------------------
+
+If there are empty .mdwn files, the po plugin displays some ugly messages.
+
+> This is due to a bug in po4a (not checking definedness of a
+> variable). One-liner patch sent. --[[intrigeri]]
+
+Translation of directives
+-------------------------

 
 

-### Misc
+If a translated page contains a directive, it may expand to some english
+text, or text in whatever single language ikiwiki is configured to "speak".

 
 

-* general test with `usedirs` disabled: **OK**
-* general test with `indexpages` enabled: **not OK**
-* general test with `po_link_to=default` with `userdirs` enabled: **OK**
-* general test with `po_link_to=default` with `userdirs` disabled: **OK**
+Maybe there could be a way to switch ikiwiki to speaking another language
+when building a non-english page? Then the directives would get translated.

 
 

-Misc. bugs
-----------
+(We also will need this in order to use translated templates, when they are
+available.)
