Can't upload test specs after moving to new machine

[khearn]

We just moved our Testlink installation from a Solaris/sparc system to a Linux/x86 system. Things are mostly working, but users are unable to upload test specs. When they try, the filename they have selected to upload is cleared, but no new test spec is created in Testlink and no error is reported to the user. This worked fine on the old machine, so I suspect we're missing something in the setup of the new machine, but we can't figure out what.

We're running Testlink 1.6.2 (yes, I know it's old, but we've had trouble upgrading), with Apache 2.2.3. I've searched through the forums for similar problems, and have confirmed (via phpinfo.php) that we have dom, xmlreader and xmlwriter enabled.

In config.inc.php, I've set TL_LOG_LEVEL_DEFAULT to EXTENDED. In the log directory, I see two log files, userlog0.log and userlog1.log. When I attempt the upload, userlog0.log gets this:

Code: Select all

[08/Nov/12 16:58:45][DEBUG][/testlink/lib/testcases/tcImport.php][admin][t6jer9m2qanc2i0da92r0f4d71]
        test /testlink/lib/testcases/tcImport.php

and userlog1.log gets this:

Code: Select all

[08/Nov/12 16:58:45][DEBUG][/testlink/lib/testcases/tcImport.php][<unknown>][<nosession>]
        SQL [1] executed [took 0.00011699999999998 secs][all took 0.00011699999999998 secs]:

        SET collation_connection = 'utf8_general_ci';

Nothing shows up at all in the apache error_log.

We've got these php packages installed:
build@polaris:# rpm -q -a | grep php
php-xmlrpc-5.1.6-20.el5_2.1
php-mysql-5.1.6-20.el5_2.1
php-pdo-5.1.6-20.el5_2.1
php-5.1.6-20.el5_2.1
php-xml-5.1.6-20.el5_2.1
php-cli-5.1.6-20.el5_2.1
php-ldap-5.1.6-20.el5_2.1
php-common-5.1.6-20.el5_2.1

Are we missing anything?

I've got no clue at this point. Nothing is indicating that something is going wrong, but the test spec doesn't get uploaded. And it used to work on the old machine. Any ideas?

Thanks,

Keith
