Previous Comments: ------------------------------------------------------------------------ [2008-11-21 11:41:57] roland dot fischer at dorobet dot com Description: ------------ I've encountered the same problem as bug 29769 - even with PHP 5.2.6, 5.2.7 RC4 and 5.2.7.7 lates build from 2008.11.21 the error happens: When using ibase_set_event_handler and there are database operations inside the event-handler-function the php-engine crashes. Without the database operations inside the event-handler-function everything is working fine. I've tried to try it with php 5.3 and 6.0 versions - but the php_interbase.dll is missing from this packages? As soon as an event is caught from the event handler function windows shows me an error report and the event-handler is dead. interestingly the loop that echoes the "sleep" continues until I close the error report from windows - than the script is stopped. No entry in the php error log about this problem. Reproduce code: --------------- function event_handler($event_name, $link) { if ($event_name == "EVT_MODUS") { echo "EVENT #".$event_name."#\r\n"; $result= ibase_query ($link, 'SELECT * FROM test'); while ($row = ibase_fetch_object ($result)) { echo 'TEST: '.$row->TEST."\n"; } ibase_free_result($result); ibase_commit($link); } } while(1) { if (isset($dbi)) ibase_close ($dbi); $dbi = ibase_connect("localhost:C:/TEST.FDB", "SYSDBA", "masterkey"); ibase_set_event_handler($dbi, "event_handler", "EVT_MODUS"); while(1){ sleep(2); echo "TS: ".strftime("%H:%M:%S")." - Sleep\n"; } } ibase_commit ($dbi); ibase_close ($dbi); Expected result: ---------------- When a firebird event is posted the event-handler-function should read all the date from the table "TEST" and echo the row "TEST". Instead it crashes the php engine..
