I'm working on a CUPS filter in C++ (g++ as compiler). The code is a authentication process and a only can release the job if the authentication is correct. If it's wrong, I have to cancel the print job.
When I print a document and the filter works, it runs a bunch of code in the authentication process, but suddenly, he stops works. If I comment a piece of code (doesn't matter what piece is), it runs correct a little more at the sequence of authentication. I tested the code when I split then, and the flow works fine.
There are a possible cause for this bug - a stack size limit, a time limit or other common bug?
Thanks.
Code:
Waiting for response of authentication (Java creates a data file)
/** Start monitor of authentication response **/
time_t starttime, now;
time(&starttime);
pthread_t thread_id = starttime;
pthread_create(&thread_id, 0, &FileManager, NULL);
do{
sleep(1);
time(&now);
}while(!file_available && difftime(now, starttime) < config.GetJobTimeout());
pthread_cancel(thread_id);
...
ReturningJob returningJob;
returningJob.Execute(path + expected_filename);
ReturningJob file
this->Fill(filepath);
std::string xml = this->GetSerializedXML();
this->SaveFile(this->GenerateFilename(path), xml);
