The EN DASH is not really required in year ranges such as 2012–2015 when
we're talking about comments in source code that is probably being
displayed in a fixed font anyway. Changing back to an ordinary hypen
allows us to make a meaningful test for use utf8.
DoUpgrade is an alias for DoBrowseRequest which doesn't get $id as a
first parameter like many actions do. Therefore determine $id like
DoBrowseRequest does: call GetId.
Don't rely on a separate upgrade action. Any request except for login
and unlock will trigger an upgrade, if you're an admin. Once the upgrade
is complete, the module will rename itself such that it will no longer
load.
Recent GNU/Linux systems use ext3 or ext4 file systems. These use HTree
to index files. Wikipedia says: "HTree indexing improved the scalability
of Linux ext2 based filesystems from a practical limit of a few thousand
files, into the range of tens of millions of files per directory. [...]
HTree indexes are available in ext3 when the dir_index feature is
enabled. [...] HTree indexes are turned on by default in ext4."
Thus, instead of working on balanced-page-directories.pl, we decided to
get rid of these sub-directories altogether.
Unfortunately, this is backwards incompatible. Users wanting to upgrade
will need to install the upgrade.pl extension in order to upgrade the
file database.
