Bug ID: 43740
Summary: MediaWiki needs first-letters-root.ser to match with
version of intl extension installed.
Product: MediaWiki
Version: 1.21-git
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: Unprioritized
Component: Categories

Issue: The collation algorithm changes slightly between different versions of
php's intl library. The first letters' algorithm we use to display the first
letters on category pages is sensitive to these changes. Specifically the
first-letters-root.ser file goes with a specific version of the icu library
used with php intl extension
Affect: Some of the category headers will be incorrect. Things may switch back
and forth between different headers. For example "Aa" was sorted under a U+214D
instead of the letter A in MatmaRex's test wiki.
----
What needs to be done:
*We need to get the version of php intl's extension in use. This will probably
have to be done by grepping for ICU version in phpinfo()'s output
*We need to have versions of first-letters-root.ser that correspond to
different versions of icu library. These are fairly easy to make (I believe).
Simply need to feed maintinance/languages/generateCollationData.php different
data files corresponding to different versions of unicode. (Need to double
check that icu library is using the unicode files we think it is. I have a
vague memory of it changing to some file from the CLDR stuff a couple versions
ago)
*Some of the docs about which data files to download for
generateCollationData.php need to be updated. Right now its telling people to
download the latest version of one file, and the version corresponding to
unicode 6.0 for another.
