From: Operating system: Linux (FC10) PHP version: 5.3.3 Package: PostgreSQL related Bug Type: Bug Bug description:pg_get_result does not block if an error occurred
Description: ------------ Continuation of http://bugs.php.net/bug.php?id=36469 -- it won't let me reopen the bug (too old?) but it still exists. (It seems to be worse on modern hardware since there are multiple CPUs and the php process never has to yield to the postgres process) The manual says that pg_get_result() will block until results are ready, but if there was any sort of error (syntax error or query error, eg table does not exist) then pg_get_result() will return immediately. This causes problems since the next command you try to run may fail because the previous command hasn't actually finished. Test script: --------------- #!/usr/local/src/php5/php-5.3.3/sapi/cli/php <?php if (!isset($_SERVER['argv'][1])) { echo "Missing sleep time\n"; exit(1); } $sleepTime = $_SERVER['argv'][1]; $connStr = sprintf("host=%s dbname=%s user=%s password=%s", 'localhost', 'testlevi', 'levi', 'levi'); ($dbconn = pg_connect($connStr)) or die("Could not connect"); $i = 0; do { pg_send_query($dbconn, 'i am a syntax error;'); pg_get_result($dbconn); usleep($sleepTime); $i++; } while (!pg_connection_busy($dbconn)); echo "got a busy signal after $i commands"; ?> (There are 2 alternate scripts in the previous bug report that effectively show the same thing) Expected result: ---------------- Should loop forever Actual result: -------------- ./test.php 0 got a busy signal after 1 commands ./test.php 10 got a busy signal after 3033 commands ./test.php 1000 (loops forever) -- Edit bug report at http://bugs.php.net/bug.php?id=52750&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=52750&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=52750&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=52750&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=52750&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=52750&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=52750&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=52750&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=52750&r=needscript Try newer version: http://bugs.php.net/fix.php?id=52750&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=52750&r=support Expected behavior: http://bugs.php.net/fix.php?id=52750&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=52750&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=52750&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=52750&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=52750&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=52750&r=dst IIS Stability: http://bugs.php.net/fix.php?id=52750&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=52750&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=52750&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=52750&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=52750&r=mysqlcfg
