Detailed Description

Life of a HttpJob

• Job is added to the QueueSet (by calling addJob() ) the HttpJob is put into the m_jobQueue where it waits for "activation" signal jobAdded is emitted
• Job is activated Job is moved from m_jobQueue to m_activeJobs and signals of the job are connected to slots (local or HttpDownloadManager) Job is executed by calling the jobs execute() method

now there are different possibilities: 1) Job emits jobDone (some error occurred, or canceled (kio)) Job is disconnected signal jobRemoved is emitted Job is either moved from m_activeJobs to m_retryQueue or destroyed and blacklisted

2) Job emits redirected Job is removed from m_activeJobs, disconnected and destroyed signal jobRemoved is emitted (HttpDownloadManager creates new Job with new source url)

3) Job emits dataReceived Job is removed from m_activeJobs, disconnected and destroyed signal jobRemoved is emitted

so we can conclude following rules:

• Job is only connected to signals when in "active" state

questions:

• update of initiatorId needed? "We update the initiatorId as the previous initiator likely doesn't exist anymore"
• blacklist or black list?
