Benchmarking refresh of a a wiki with 25 thousand pages showed
file_pruned() using most of the time. But, when refreshing, ikiwiki already
knows about nearly all the files. So we can skip calling file_pruned() for
those it knows about. While tricky to do, this sped up a refresh (that
otherwise does no work) by 10-50%.

Nothing case-oriented going on in here.

Here I was bitten by perl's aliasing of foreach variables
to the loop array contents, and match_link accidentially changed
the contents of %links.
In Jon's testcase, a tag added an absolute link, which was
made relative by the above bug, and then the link was added
again in preprocess, and turned into a duplicate.

I weakended the regexp, so this matches ipv6 addresses too. It does not
ensure that the address is valid, but that should not matter here.
Note that addresses ending in "::" are not matched, so eg, the unspecified
address will not match -- but should never appear here anyway.

template files in.

This avoids a lot of unncessary stats, and trims about 1 second
off a docwiki rebuild here.

It's not "exact" since case munging has to be done, and I think
"simple" captures the optimisation better.</pedant>
With apologies to smcv, who probably has to rebuild his wiki now.

single page
Let E be the number of dependencies per page of the form "A depends on B and
nothing else", let D be the number of other dependencies per page,
let P be the total number of pages, and let C be the number of changed
pages in a refresh.
This patch should speed up a refresh from O(E*C*P + D*C*P) to
O(C + E*P + D*C*P), assuming that hash lookups are O(1).
In practice, plugins like inline and map produce a lot of these very simple
dependencies, and my album plugin's combination of inline with a large
number of pages causes it to suffer particularly badly.
In testing on a wiki with about 7000 objects (3500 full pages, 3500
images), a full rebuild continued to take about 5:30, and a refresh
after touching about 350 pages and 350 images reduced from 5:30 to 1:30.
As with my previous optimizations, this change will result in downgrades not
working correctly until the wiki is rebuilt.

This reverts commit e4cd168ebedd95585290c97ff42234344bfed46c.
There was no benefit to this change.

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).
|
|
This relies for its correctness on %config, %hooks and pagetype() not
changing.

As per Joey's review.

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.

This assumes that no ctime means the page doesn't exist, which seems
reasonable.

The gettext call can clear $@ in at least some cases.
|
|
By adding this setting, we get both more configurability, and a minor
optimisation too, since gettext does not need to be called continually
to get the Discussion value.

On various sites I have two IkiWiki instances running from the same
repository: one accessible via http and only accepting openid logins,
and one accessible via authenticated https and only accepting httpauth.
The https version should still pretty-print OpenIDs seen in git history,
even though it does not itself accept OpenID logins.

available.
The test suite was emitting a lot of ugly gettext warnings;
setting LC_ALL didn't solve the problem for all locale setups
(since ikiwiki remaps it to LANG, and ikiwiki didn't know about
the C locale).
People also seem generally annoyed by the messages when
Locale::Gettext is not installed, and I suspect will be
generally happier if it just silently doesn't localize.
The optimisation came about when I noticed that the gettext
sub was doing rather a lot of work each call just to see
if localisation is needed. We can avoid that work by caching,
and the best thing to cache is a version of the gettext sub
that does exactly the right thing.
This was slightly complicated by the locale setting,
which might need to override the original locale (or lack
thereof) after gettext has been called. So it needs to invalidate
the cache in that case. It used to do it via a global variable,
which I am happy to have also gotten rid of.

Do not allow an unterminated """ string to be treated as a series of bare
words. Fixes runaway regexp recursion/backtracking in strange situations.
(See 1d57a21c987a5e970df01efe10acdf69982c2d61 for test case.)

And avoid a whole class of potential security problems (though
none that I know of actually existing..), by avoiding
performing any string interpolation on user-supplied data when translating
pagespecs.

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.

This reverts commit 2f96c49bd1826ecb213ae025ad456a714aa04863.
I forgot about internal pages. We don't want * matching them!
I left the optimisation in pagecount, where it used to live.
Internal pages probably don't matter when they're just being
counted.
|
|
Add an optimisation for the semi-common case of a "*" pagespec. Can
avoid doing any real processing in this case.
|
|
* pagespec_match_list: New API function, matches pages in a list
and throws an error if the pagespec is bad.
* inline, brokenlinks, calendar, linkmap, map, orphans, pagecount,
pagestate, postsparkline: Display a handy error message if the pagespec
is erronious.
|
|
* Add IkiWiki::ErrorReason objects, and modify pagespecs to return
them in cases where they fail to match due to a configuration or syntax
error.
* inline: Display a handy error message if the inline cannot display any
pages due to such an error.
This is perhaps somewhat incomplete, as other users of pagespecs do not
display the error, and will eventually need similar modifications to inline.
I should probably factor out a pagespec_match_all function and make it throw
ErrorReasons.

The problem was introduced by the recent noextension patches.
Object autovivification caused junk to get into %htmlize,
and all keys of that showed up as page types.
|
|
Because getopt::long is used in passthrough mode, if a known
option like --wikiname that needs a parameter is specified w/o
the parameter, it will not be processed, and passed on through.
So in this case the "unknown option" message is innaccurate.
Make it slightly better by noting that the problem can be a missing
parameter.

It no longer makes sense to keep these functions in editpage, because
serveral plugins now exist that use them, and users may want to disable
editpage, while leaving those plugins enabled.
Most notably, comments uses both functions, and it's entirely appropriate
to disable editpage but still want to have comments enabled.
Less likely, attachments, rename, and remove all use check_canedit -- but
it would be unusual indeed to want to use these w/o editpage.

It enables debug prints, so not just during building, but at runtime.

It used to replace unknown functions with "0" when translating a pagespec.
Instead, replace it with a FailReason object. This way, the pagespec will
still evaluate as before (possibly successfully if other terminals exist),
but a human-readable error will be shown if the result is displayed.
Also, an empty pagespec used to be replaced with "0", to avoid a eval
error. Also use a FailReason here.
