[SOLVED] Best way to use ?

Hello there,
I've some troubles with the irc2sql module of anope, so I decided to use xmlrpc to get live infos about the channels, and I need some advices.
On the channel page, I've several info about the channel, perfect, but also about the users: nick, level, realname, country, away (when the PR will be accepted
) and modes (to check if it's a bot or not). To get these infos, I can:
- use channel->get() with level 5 => could make a really big object
- use channel->get() normaly (level 3) and loop on the members to do a user->get() with level 2 => could do a lot of queries
Which solution could be the best ? Or do you have another one ?

I would certainly not do the 2nd method. You could do the 1st, yeah, but then for sure cache the response for like 5 or 10 seconds, so it can be re-used by other people loading that page. If it's PHP, I usually use memcache for that, where you can just throw a key = value in, with "key" being or containing the channel name and the "value" being the server response (the entire JSON string).

I was thinking about using a cache, but make by myself: a simple text file per channel, and check of the modification date. And probably the cache will contain the html I generate, so I just read and display rather than reparse datas. And 10s seems a good rate
Thanks Syzop

Here is the way I cache my datas, simple but working:
Code: Select all
function chanCache($chan) {
global $unrealapi;
$file = '/tmp/'.$chan.'.tmp';
if (!is_file($file) || filemtime($file)<(time()-10)) {
$rpc = new UnrealIRCd\Connection("wss://127.0.0.1:8600/", $unrealapi, ['tls_verify' => FALSE]);
$uchannel = $rpc->channel()->get('#'.$chan, 5);
$fo = fopen($file, 'w');
fputs($fo, serialize($uchannel));
fclose($fo);
}
return unserialize(file_get_contents($file));
}
No need to use memcache, fully portable on any configuration
I know use json-RPC for the live datas (
https://zeolia.chat/canaux/ and any channel page), and also for the webmasters tools (
https://zeolia.chat/outils/ , tab "Afficher vos statistiques")
Just waiting for the 6.2.1 to add the AWAY

Syzop kindly gave me some tips on how to improve and secure my caching function, so here is the result:
Code: Select all
function chanCache($chan) {
global $unrealapi;
$file = '/tmp/'.hash('sha256', $chan).'.src';
if (!is_file($file) || filemtime($file)<(time()-10)) {
$rpc = new UnrealIRCd\Connection("wss://127.0.0.1:8600/", $unrealapi, ['tls_verify' => FALSE]);
$uchannel = $rpc->channel()->get('#'.$chan, 5);
$fo = fopen($file.'.tmp', 'w');
fputs($fo, serialize($uchannel));
fclose($fo);
rename($file.'.tmp', $file);
}
return unserialize(file_get_contents($file));
}
Thanks
