[PHP-DEV] PHP 4.0 Bug #7554: Exclusive flock() breaks client/server communication From: php <email protected>

Bug description: Exclusive flock() breaks client/server communication

A 2nd exclusive flock() - or a try to do so - causes a kind of infinite loop. Browser(s) are not responding. The Apache-process is allowed to write to /tmp.

    $fp1 = fopen("/tmp/test.txt","a");
    if (!$fp1) die("cant open file 1");
    if (!flock($fp1,2)) die("cant lock file 1");
    
    $fp2 = fopen("/tmp/test.txt","a");
    if (!$fp2) die("cant open file 2");

    // causes troubles
    if (!flock($fp2,2)) die("cant lock file 2");
    
    fclose($fp2);
    fclose($fp1)

My configure:

'./configure' '--with-apxs=/usr/local/httpd/bin/apxs' '--with-config-file-path=/usr/local/httpd/conf' '--enable-track-vars' '--with-gdbm' '--enable-ftp' '--with-gd' '--with-ttf=/usr/include/freetype' '--enable-sysvshm' '--enable-sysvsem' '--with-openssl=../openssl-0.9.5a' '--with-imap=../imap-4.7c' '--with-pdflib' '--enable-sockets' '--with-mysql=/usr/local/mysql' '--with-oci8=/opt/oracle/product/8.1.5' '--with-sablot'
