#43219 [NEW]: connection_status() CAN function properly without output

From: php at alterego dot dp dot ua Operating system: Any PHP version: 5.2.5RC2 PHP Bug Type: Apache related Bug description: connection_status() CAN function properly without output Description: ------------ Please regard this comment seriously, it really contains information on how to fix 25266, 22072, 30301 and many other (NOT bogus) bugs under Apache SAPI. From bug 25266 comment by iliaa@php.net: > Apache provides a way for PHP to detect if connection was > aborted ONLY and ONLY when PHP is either reading data from > the user or writing back data. That is not true. This link contains description and code (mod_perl) on how to detect disconnection without flushing data: http://www.webreference.com/programming/perl/cookbook/chap4/5.html My untidy but WORKING solution was to add code given below to sapi_apache_flush function and call flush() function before connection_aborted() checks WITHOUT any output. Of course, it would be perfectly logical to add it to connection_aborted function itself, but I could not find any way to call SAPI-specific function from core. Working code is: int fd; struct timeval tv = {0,0}; fd_set set; if (server_context) { request_rec *r = SG(server_context); fd = ap_bfileno(r->connection->client, B_WR); if (fd >= 0) { FD_ZERO(&set); FD_SET(fd, &set); if (select(fd + 1, &set, NULL, NULL, &tv) >= 0 && FD_ISSET(fd, &set)) { php_handle_aborted_connection(); } } } -- Edit bug report at http://bugs.php.net/?id=43219&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=43219&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=43219&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=43219&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=43219&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=43219&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=43219&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=43219&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=43219&r=needscript Try newer version: http://bugs.php.net/fix.php?id=43219&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=43219&r=support Expected behavior: http://bugs.php.net/fix.php?id=43219&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=43219&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=43219&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=43219&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=43219&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=43219&r=dst IIS Stability: http://bugs.php.net/fix.php?id=43219&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=43219&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=43219&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=43219&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=43219&r=mysqlcfg
