This is for those situations where something basically impossible happens,
like $context->contextlevel not having one of the valid value, and you
want to throw an exception (for example in the default: case of a switch)
rather than just ignoring the possibility.
This was a Google Summer of Code 2007 Project.
This introduces two new files, admin/cliupgrader.php and lib/installlib.php.
It also introduces a new PEAR library, Console_GetOpt. I have recieved permission from the upstream author to include this in GPL Moodle (essentially dual license it) - notes in lib/pear.
Most stuff that outputs html during install gets suppressed by the use of a constant.
Run the script like php admin/cliupgrade.php --help for info.
Note that this all uses strings from install/ rather than lang, so I have updated stringnames.txt accordingly and they'll all be broken until the cronjob that generates them runs.
We now have a wrapper memcached support class to handle
initial connection setup, provide the common denominator
calls, plus getforfill() and friends.
The eaccelerator class now returns false to match memcached. The
downside of this is that we cannot store booleans as a false value
is indistinguishable from a false that indicates error or 'key not
found'.
Make pconnections optional - only use pconnect if $CFG->memcachedpconn is
set. In current versions of the memcache client in PECL (v2.0.1),
memcache_pconnect() is buggy and will segfault if reusing a pconnection
to a server that has gone away or restarted.
And hope for a more stable client library in PECL ;-)
$MCACHE is initially based on core API that is shared between memcached and
turckmmcache/eaccelerator. The core operations are add(), set() and delete()
This initial implementation uses the PECL-based PHP client. Would be trivial
to add support for a PHP-based client.
The $MCACHE facility can be used for DB cache, text filters cache, and possibly
for sessions.
On 64-bit platforms the in-memory footprint of our libraries is quite a bit
larger than usual, and we hit the 8MB default memory limit before we call
raise_memory_limit(). This patch moves raise_memory_limit() and
get_realsize() to setuplib so we can call them earlier, and moves the
call to _before_ we include the libraries.
On AMD64, for MOODLE_17_STABLE the footprint is about 9.5MB. Diet time? :-)
