Description:
------------
NOTE: all of this happens when using PHP from the command line, don't
know about other cases, that is harder to measure.
Using oci_connect with PHP 5.3.2 (or 5.3.1 or snap php5.3-201006161430)
against Oracle 10.2.0.4 causes a PHP script to hang for about a second
after all code has been run. Script doesn't crash, just takes way too
long to finish.
i.e. one can do something like this
print "FIRST LINE OF CODE\n";
oci_connect('user', 'pass');
print "LAST LINE OF CODE\n";
and after "LAST LINE OF CODE" is printed, the program will hang for
about a second, then finish. If you remove the oci_connect line, the
program runs without any post-code hangup. PHP 5.2 on the same machine
runs with no problems.
Note: the problem happens if the user/pass are correct or not.
What works and what doesn't against Oracle 10.2.0.4:
PHP 5.2 (oci8 1.2.4) -> works fine
PHP 5.3.1 (oci8 1.3.5) -> hangs for around one second
PHP 5.3.2 (oci8 1.4.1) -> hangs for around one second
PHP 5.3-201006161430 (oci8 1.4.2-dev) -> hangs for around one second
What works and what doesn't against Oracle 10.2.0.3:
PHP 5.2 (oci8 1.2.4) -> works fine
PHP 5.3.1 (oci8 1.3.5) -> works fine
PHP 5.3.2 (oci8 1.4.1) -> works fine
PHP 5.3-201006161430 (oci8 1.4.2-dev) -> works fine
Seems to be related to 10.2.0.4 and certain versions of PHP's oci8.
All these PHP's were built with the same configure line:
./configure --prefix=/opt/php --with-oci8
--with-apxs2=/opt/apache2/bin/apxs --enable-ftp --with-xmlrpc
--with-iconv --with-curl --with-pear --enable-pcntl --with-zlib
--with-readline
I have tested everyone of the above PHP's using 'php -n' (no php.ini).
Again, the bug only manifests on Oracle 10.2.0.4.
Test script:
---------------
<?php
#run this script from the command line with the 'time' command on linux,
like so, to see the problem:
#
# time php -n myscript.php
#
print "before connect: ".microtime(true)."\n";
oci_connect('user', 'pass');
print "after connect: ".microtime(true)."\n";
#Note that the slowdown isn't bound to oci_connect,
#The two print statements will happen BEFORE the slowdown occurs,
#i.e. after all PHP code has been processed.
#using strace on the script with the '-c' is also interesting...
?>
Expected result:
----------------
I expect the script to complete in .05 to .15 seconds (or so).
Actual result:
--------------
Script takes at least a full second to finish, after all code has been
executed.
