CollationFa was removed in 5a21de8abb7f03e72a07d8578babc1835dff4a64, because it is no longer necessary.

Marking this resolved because I can't think of any other customizations that would have to be fixed.

I believe I meant you should change .com-google-gerrit-client-diff-DiffTable_BinderImpl_GenCss_style-table to .com-google-gerrit-client-diff-DiffTable_BinderImpl_GenCss_style-table .CodeMirror. I did test this using Firefox Developer Tools, though not by editing GerritSite.css. (I do not have Gerrit installed locally.)

@PleaseStand hi but we do

white-space: pre-wrap !important;
}
with
.CodeMirror
Would you show me what css to use please from the above.

There should be no way this backtrace could have been generated unless the value of the constant INF is not greater than 0, and that should not happen.

@PleaseStand I think we can simply backport the patch to our current version of HHVM, by the way, in order to make the behaviour consistent. We won't need to remove the null byte then, AIUI.

Or rather, trimming the null byte off in IcuCollation should address the major problem with CategoryViewer's pagination on frwiki.

Stripping it may be ok for newer , but may present an issue to those running older PHP/HHVM versions. Depends on how exactly the keys are used - what the lifecycle is, I guess.

Already fixed in rMWb6487447463de476.

Per T130692, the cl_collation_ext index was added to Wikimedia databases for use by updateCollation.php. @jcrespo, has the old cl_collation index been removed everywhere, including on the sites that the new index had already been added to? If so, this task can be closed.

This might result in inconsistent normalization when some inputs contain invalid UTF-8 sequences yet do not contain any character having, according to Unicode 6.0, a non-zero canonical combining class or an NFC_QC value of No or Maybe.

I'd guess it's probably not a blocker since we probably use the intl extension rather than those data tables on the cluster, and the same for the Scribunto bits. So it's probably more of a cleanliness thing.

Florian's change was abandoned and not merged, so reopening.

The patch I uploaded fixes the reported issue by removing the document.write() wrapper around the site notice HTML. However, there is a concern that this would cause the site notice to be indexed and displayed within search engine snippets. I do not know of a way I can confidently avoid this problem.

the recount method gets a shared lock on all the categorylinks entries for that category

That is worrying- with InnoDB, while inside a transaction, you do not need to lock the rows- it should get consistent reads automatically.

Without locking, pages getting added and removed from the category while the SELECT gets the new counts will not be counted correctly.

The packagist page https://packagist.org/packages/wikimedia/ip-set has 1.0 and 1.0.1 listed. I am not sure how from where they come from.

The best solution is probably to add an index on (cl_collation, cl_to, cl_type, cl_from)

I added the 1.27 PHP compatibility information (diff), though have not yet reviewed the existing information for accuracy. I have not added HHVM information because it is not clear what the minimum supported version of HHVM is; RELEASE-NOTES-1.27 is currently inconsistent on the matter.

Circling back around to this and looking again: of course it's possible that a better answer here is to refactor recOptimize and recCompress to use loops in place of recursion. In theory, recursive things can always be rewritten as loops that maintain some kind of state-stack variable, e.g. an array stack that grows by one entry for each virtual level of recursion in the loop.
The upside is it could remove the constraint that using this module requires setting a special interpreter/engine config variable in the common case. The primary potential downside is that the code might get more-unreadable (and it's already pretty bad). The other potential fallout is of course the perf impact of that refactor is an unknown, but I'd expect perf improvement, and in the constructor case perf isn't as important as it is in match()

Finding 0 now works. For example:

@Jules78120 reported an issue with MediaWiki:AnonNotice on the French Wikipedia today, where the notice was added at the bottom left of the page and not at the top.
Could this be related to the use of document.write as well?
