Member Function Documentation

◆ CheckAuthDone()

bool CheckAuthDone	(	std::string const &	Message,
		pkgAcquire::MethodConfig const *const	Cnf
	)

protected

Called when authentication succeeded.

Sanity-checks the authenticated file, queues up the individual index files for download, and saves the signature in the lists directory next to the authenticated list file.

Parameters

Message	The message block received from the fetch subprocess.
Cnf	The method and its configuration which handled the request

◆ CheckDownloadDone()

bool CheckDownloadDone	(	pkgAcqTransactionItem *const	I,
		const std::string &	Message,
		HashStringList const &	Hashes
	)		const

protected

Called when a file is finished being retrieved.

If the file was not downloaded to DestFile, a copy process is set up to copy it to DestFile; otherwise, Complete is set to true and the file is moved to its final location.

Parameters

Message The message block received from the fetch subprocess.
