sfAutoload produces a PHP warning on unlink file

[fruit]

When the debug mode is ON, sometimes this line:

sfAutoload.class.php#L134

produced error message:

PHP Warning:  unlink(/project/cache/api/dev/config/config_autoload.yml.php): No such file or directory in /project/vendor/lexpress/symfony1/lib/autoload/sfAutoload.class.php on line 134
PHP Stack trace:

PHP  30. unlink() /project/vendor/lexpress/symfony1/lib/autoload/sfAutoload.class.php:134

I know, this it not good approach, but placing a @ before unlink will solve the issue.

Also, file_exists can be replaced with is_file (it's a correct way to check file existence)

Yeah as far as I remember, I also got that error from time to time and I still didn't understand why if the previous condition about file_exists is true this error appear when trying to remove the file ... 😶

Because file state is cached during single PHP request...

I would add a clearstatcache(); call here:

File: sfApplicationConfiguration.class.php#L113

$this->dispatcher->connect('autoload.filter_config', array($this, 'filterAutoloadConfig'));
sfAutoload::getInstance()->register();
if ($this->isDebug())
{
   clearstatcache(); // HERE
   sfAutoloadAgain::getInstance()->register();
}

Or somewhere here:

File: sfAutoload.class.php#L132

if (file_exists($configuration->getConfigCache()->getCacheName('config/autoload.yml')))
{
   unlink($configuration->getConfigCache()->getCacheName('config/autoload.yml'));
   clearstatcache(); // HERE
}

This warning will appear on reloading data sometimes.

<b>Warning</b>: unlink(/var/www/xxx/cache/api/test/config/config_autoload.yml.php): No such file or directory in <b>/var/www/xxx/vendor/friendsofsymfony1/symfony1/lib/autoload/sfAutoload.class.php</b> on line <b>136</b><br />

This error is still open, would it make sense to fix it?

no longer relevant to me
