+Here is the code. As you can see, sort="age" is equivilant to leaving
+out the sort option. --[[Joey]]
+
+ if (exists $params{sort} && $params{sort} eq 'title') {
+ @list=sort { pagetitle(basename($a)) cmp pagetitle(basename($b)) } @list;
+ }
+ elsif (exists $params{sort} && $params{sort} eq 'mtime') {
+ @list=sort { $pagemtime{$b} <=> $pagemtime{$a} } @list;
+ }
+ elsif (! exists $params{sort} || $params{sort} eq 'age') {
+ @list=sort { $pagectime{$b} <=> $pagectime{$a} } @list;
+ }
+ else {
+ return sprintf(gettext("unknown sort type %s"), $params{sort});
+ }
+
+> On further testing, I find that the bug is limited to the first time

+> 1. Create pages that sort different by mtime and ctime

+> 3. ikiwiki --setup setup_file
+>
+> 4. Pages are output incorrectly in mtime order
+>
+> 5. ikiwiki --setup setup_file
+>
+> 6. Pages are output correctly in ctime order

+> 7. Create new page in somepages/, set its ctime to earlier than another

+>
+> 8. ikiwiki --setup setup_file
+>
+> 9. All previously sorted pages output correctly in ctime order but new
+> page is output incorrectly at the top as if its mtime was its ctime
+>
+> 10. ikiwiki --setup setup_file
+>
+> 11. All pages, including new page, are output correctly in ctime order
+
+You're confusing ctime and creation time. This is perhaps not suprising, as
+ikiwiki uses the term 'ctime' to refer to creation time. However, the unix
+ctime value is not the same thing. Unix ctime can change if a file changes
+owner, or in some cases, permissions. Unix ctime also always changes
+when the file is modified. Ikiwiki wants a first creation date of the file,
+and it accomplishes this by recording the initial ctime of a file the first
+time it processes it, and *preserving* that creation time forever, ignoring
+later ctime changes.
+
+I suspect that this, coupled with the fact that ikiwiki sorts newest pages
+first, explains everything you describe. If not, please send me a shell script
+test case I can run, as instructions like "Create pages that sort different by
+mtime and ctime" are not ones that I know how to follow (given that touch sets
+*both*). --[[Joey]]

+>
+> 1. Create pages in the srcdir that should sort in one order by

+> time. For example:
+>
+> $ echo -e '\[[!meta date="2007-01-01"]]\nNew.' > test/new.mdwn
+> $ echo -e '\[[!meta date="2006-01-01"]]\nOld.' > test/old.mdwn
+>
+> 2. Create a page that includes the files. For example:
+>
+>
+> $ echo '\[[!inline pages="test/*"]]' > sort-test.mdwn
+>
+> 3. Run ikiwiki. For example `ikiwiki --setup setup_file`
+>
+> 4. Pages are output incorrectly in modification time order. For example,
+> actual partial HTML of the sort-test/index.html from commands used
+> above (whitespace-only lines removed; one whitespace-only line
+> added):
+>
+> <div class="inlinepage">
+> <span class="header">
+> <a href="./../test/old/">old</a>
+> </span>
+> <p>Old.</p>
+> <span class="pagedate">
+> Posted Sun 01 Jan 2006 12:00:00 AM EST

+> <span class="pagedate">
+> Posted Mon 01 Jan 2007 12:00:00 AM EST
+> </span>
+> </div>
+>
+> 5. Run ikiwiki again with the same command line. For example: `ikiwiki --setup setup_file`
+>
+> 6. Pages are output correctly in creation time order. For example,
+> actual partial HTML of the sort-test/index.html from commands used

+> 7. Create a new page with the current Unix mtime and Unix ctime, but a

+Thank you for a textbook excellent reproduction recipe.
+
+What appears to be going on here is that meta directives are not processed
+until the leaf pages are rendered, and thus the ctime setting is not
+available at the time that they are inlined, and the newer unix ctime is
+used. On the second build, the meta data has already been recorded.
+
+This can probably be avoided by processing meta date at scan time.
+
+Verified, fix works. [[done]]
