Several universities have reported that creating a software profile
hangs the machine running the ogServer for a while, sometimes up to
minutes.
Legacy SQL code is producing said bottleneck, responsible for pruning a
intermediate table between "perfilessoft" and "softwares". There is
redundant code, "perfilssoft" should be pruned first, speeding up the
later task of pruning the intermediate table "perfilessoft_softwares"
There is no need to execute:
DELETE FROM perfilessoft_softwares
WHERE idperfilsoft IN (
SELECT idperfilsoft
FROM perfilessoft
WHERE idperfilsoft NOT IN (
SELECT DISTINCT idperfilsoft
from ordenadores_particiones)
AND idperfilsoft NOT IN (
SELECT DISTINCT idperfilsoft from imagenes))
When afterwards "perfilessoft" is going to be pruned and
"perfilessoft_softwares" pruned again:
DELETE FROM perfilessoft WHERE idperfilsoft NOT IN
(SELECT DISTINCT idperfilsoft from ordenadores_particiones)
AND idperfilsoft NOT IN
(SELECT DISTINCT idperfilsoft from imagenes)
DELETE FROM perfilessoft_softwares WHERE idperfilsoft NOT IN
(SELECT idperfilsoft from perfilessoft)
The two latter commands suffice.
This should not happen when using a relational database supporting
foreign keys and ON DELETE CASCADE, like innoDB, which will be adopted
soon.
Use og_server_cfg everywhere. Convert port to string to make it easy for the
dbi API since it expects a string. Remove legacy example configuration file.
Some universities have computers in a different subnet where the
ogServer is, but ogServer WoL functionality only supported to send
packet to its own subnets. This commit solves this.
Now ogServer sends two WoL packets per client, one with the broadcast
address of the interface indicated in the config file, the other with
the broadcast address calculated with the address and netmask of the
client.
To ensure that the second WoL works correctly you must configure
correctly the IP and netmask of the clients. Also, you have to configure
the network of your organization to route WoL packet to the correct
subnet.
