Hello everyone,

maybe i didn't understood what bubbling means, but following code display all log messages in firebug console

$logger = new Monolog\Logger($channelName);
$firePHPHandler = new \Monolog\Handler\FirePHPHandler(Psr\Log\LogLevel::DEBUG,false);
$logger->pushHandler($firePHPHandler);
$logger->debug('Test Debug');
$logger->info('test info');
$logger->info('test info');
$logger->info('test info');
$logger->warning('test warning');

but i expected to see only debug message, in my code i use info and warning logs with different handler and the debug schould be a replacement for var_dump

maybe i used it wrong?

also if i add ChromePHPHandler

$logger = new Monolog\Logger($channelName);
$firePHPHandler = new \Monolog\Handler\FirePHPHandler(Psr\Log\LogLevel::DEBUG,false);
$logger->pushHandler($firePHPHandler);
$chromePHPHandler = new \Monolog\Handler\ChromePHPHandler(Psr\Log\LogLevel::DEBUG,false);
$logger->pushHandler($chromePHPHandler);
$logger->debug('Test Debug');
$logger->info('test info');
$logger->info('test info');
$logger->info('test info');
$logger->warning('test warning');

there are no logs anymore in FirePHP Console, only in ChromePHP, however if i add the chrome handler to buffer handler

$logger = new Monolog\Logger($channelName);
$firePHPHandler = new \Monolog\Handler\FirePHPHandler(Psr\Log\LogLevel::DEBUG,false);
$logger->pushHandler($firePHPHandler);
$chromePHPHandler = new \Monolog\Handler\ChromePHPHandler(Psr\Log\LogLevel::DEBUG,false);
$logger->pushHandler(new \Monolog\Handler\BufferHandler($chromePHPHandler));
$logger->debug('Test Debug');
$logger->info('test info');
$logger->info('test info');
$logger->info('test info');
$logger->warning('test warning');

then i see the log messages in Chrome and Firefox but still all messages are displayed, while bubbling is deaktivated.

is this a real bug? or just wrong usage?

Cheers

Well, given you pushed a ChromephpHandler on the stack and it disables bubbling, no messages will go to the next handler in the stack. So it is expected that firefox does not receive log messages anymore.
when you use the BufferHandler, you see logs in firefox because the BufferHandler itself allows bubbling in your code.

And the level they accept is the min level for which they handle messages. Setting the level to debug will accept anything.

If you want to display only debug messages in chrome and firefox, there is 2 solutions:

push the handler for the Info+ level after the chrome and firefox handlers (so that it is first in the stack) and prevent bubbling in this one (so that Info+ messages are stopped before reaching these browser handlers but debug messages go through as they are not handled)
wrap the firefox and chrome handlers in a FilterHandler accepting only debug messages (and don't change the message bubbling at all)
