{panel}
\Doctrine\ORM\Proxy\ProxyFactory::_generateProxyClass fails to rename temporary proxy files when proxies are generated on demand in multiprocess environment using Process Control extension under Linux (http://www.php.net/manual/en/book.pcntl.php). 'Message: rename(../cache/Proxy/Dlayer/__CG__DlayerEntityInventory.php.520d1708631ed2.21378588,/../cache/Proxy/Dlayer/_CG_DlayerEntityInventory.php): No such file or directory' message is given.
{panel}

  • It seems that when two parallel processes are trying to generate a proxy for the same entity, the uniqid function does not create unique temporary file names per process.
  • Also the check should be made at the time of renaming to make sure that the proxy with the same name was not already created in a parallel process.
