Add preprocessed 'use lib' line to ikiwiki-transition and ikiwiki-calendar if necessary for unusual install.
rework dependency types code Simplify, change default content depends number to 1, change interface to make more sense.
set dependency hash value properly for new dependency types Just "1" won't cut it anymore; we need to list all the dependency types.
Remove now-unused function pagespec_merge Now that dependencies are a list of pagespecs with an implicit "or" operation, there's no need to try to merge pagespecs under normal use. ikiwiki-transition contains the only use of the function, so move it there rather than deleting it entirely (it's used to concatenate all admins' lists of locked pages).
Use a hash to de-duplicate dependencies
Optimize the dependencies list On a large wiki you can spend a lot of time reading through large lists of dependencies to see whether files need to be rebuilt (album, with its one-page-per-photo arrangement, suffers particularly badly from this). The dependency list is currently a single pagespec, but it's not used like a normal pagespec - in practice, it's a list of pagespecs joined with the "or" operator. Accordingly, change it to be stored as a list of pagespecs. On a wiki with many tagged photo albums, this reduces the time to refresh after `touch tags/*.mdwn` from about 31 to 25 seconds. Getting the benefit of this change on an existing wiki requires a rebuild.
ikiwiki-transition: deduplinks was broken and threw away all metadata stored by plugins in the index. Fix this bug.
fix
ikiwiki-transition: Allow setup files to be passed to all subcommands that need a srcdir.
ikiwiki-transition: If passed a nonexistant srcdir, or one not containing .ikiwiki, abort with an error rather than creating it.
Avoid %links accumulating duplicates. (For TOVA) This is sorta an optimisation, and sorta a bug fix. In one test case I have available, it can speed a page build up from 3 minutes to 3 seconds. The root of the problem is that $links{$page} contains arrays of links, rather than hashes of links. And when a link is found, it is just pushed onto the array, without checking for dups. Now, the array is emptied before scanning a page, so there should not be a lot of opportunity for lots of duplicate links to pile up in it. But, in some cases, they can, and if there are hundreds of duplicate links in the array, then scanning it for matching links, as match_link and some other code does, becomes much more expensive than it needs to be. Perhaps the real right fix would be to change the data structure to a hash. But, the list of links is never accessed like that, you always want to iterate through it. I also looked at deduping the list in saveindex, but that does a lot of unnecessary work, and doesn't completly solve the problem. So, finally, I decided to add an add_link function that handles deduping, and make ikiwiki-transition remove the old dup links.
fix moveprefs transition
make ikiwiki-transition prefix_directives take a setup file This is easier to remeber, and less error-prone than passing it all the pages in the wiki.
remove deprecated admin prefs A new ikiwiki-transition moveprefs subcommand can pull the old data out of the userdb and inject it into the setup file. Note that it leaves the old values behind in the userdb too. I did this because I didn't want to lose data if it fails writing the setup file for some reason, and the old data in the userdb will only use a small amount of space. Running the command multiple times will mostly not change anything.
enable aggregate_internal by default
add a guard against multiple cgi or rcs wrappers
add ikiwiki-transition setupformat subcommand. Also fixed a bug in how aggregateinternal used IkiWiki::Setup::load, and added checks for arguments to other subcommands.
Fix aggregateinternal migration so it skips expired entries, and deletes output
Add aggregateinternal mode to ikiwiki-transition. Usage: 1. Update all pagespecs that use aggregated pages to use internal() 2. ikiwiki-transition aggregateinternal $srcdir $htmlext (where $srcdir and $htmlext are the srcdir and htmlext options in your .setup file) 3. Add aggregateinternal to your .setup file 4. Rebuild the wiki
ikiwiki-transition: Fix command-line processing so the prefix_directives transition works again.
