Detailed Description

Implementation class for CIFS MediaHandler.

NOTE: The implementation serves both, "smb" and "cifs" URL's, but passes "cifs" to the mount command in any case.

Member Function Documentation

void zypp::media::MediaCIFS::attachTo ( bool next = false )

protectedvirtual

Asserted that not already attached, and attachPoint is a directory.

Authentication: credentials can be specified in the following few ways (the first has the highest preference).

URL username:password
mountoptions URL query parameter (see man mount.cifs)
CredentialManager - either previously saved credentials will be used or the user will be promted for them via AuthenticationReport callback.

Note: The implementation currently serves both, "smb" and and "cifs" URL's, but passes "cifs" to the mount command in any case.

Implements zypp::media::MediaHandler.

Definition at line 129 of file MediaCIFS.cc.

void zypp::media::MediaCIFS::releaseFrom ( const std::string & ejectDev )

protectedvirtual

Call concrete handler to release the media.

If eject is true, and the media is used in one handler instance only, physically eject the media (i.e. CD-ROM).

Asserted that media is attached.

Parameters

ejectDev Device to eject. None if empty.

Exceptions

MediaException

Implements zypp::media::MediaHandler.

Definition at line 343 of file MediaCIFS.cc.

void zypp::media::MediaCIFS::getFile ( const Pathname & filename ) const

protectedvirtual

Call concrete handler to provide file below attach point.

Default implementation provided, that returns whether a file is located at 'localRoot + filename'.

Asserted that media is attached.

Exceptions

MediaException

Implements zypp::media::MediaHandler.

Definition at line 356 of file MediaCIFS.cc.

void zypp::media::MediaCIFS::getDir	(	const Pathname &	dirname,
		bool	recurse_r
	)		const

protectedvirtual

Call concrete handler to provide directory content (not recursive!) below attach point.

Return E_not_supported_by_media if media does not support retrieval of directory content.

Default implementation provided, that returns whether a directory is located at 'localRoot + dirname'.

Asserted that media is attached.

Exceptions

MediaException

Implements zypp::media::MediaHandler.

Definition at line 368 of file MediaCIFS.cc.

void zypp::media::MediaCIFS::getDirInfo	(	std::list< std::string > &	retlist,
		const Pathname &	dirname,
		bool	dots = `true`
	)		const

protectedvirtual

Call concrete handler to provide a content list of directory on media via retlist.

If dots is false entries starting with '.' are not reported.

Return E_not_supported_by_media if media does not support retrieval of directory content.

Default implementation provided, that returns the content of a directory at 'localRoot + dirnname' retrieved via 'readdir'.

Asserted that media is attached and retlist is empty.

Exceptions

MediaException

Implements zypp::media::MediaHandler.

Definition at line 381 of file MediaCIFS.cc.

void zypp::media::MediaCIFS::getDirInfo	(	filesystem::DirContent &	retlist,
		const Pathname &	dirname,
		bool	dots = `true`
	)		const

protectedvirtual

Basically the same as getDirInfo above.

The content list is returned as filesystem::DirContent, which includes name and filetype of each directory entry. Retrieving the filetype usg. requires an additional ::stat call for each entry, thus it's more expensive than a simple readdir.

Asserted that media is attached and retlist is empty.

Exceptions

MediaException

Implements zypp::media::MediaHandler.

Definition at line 395 of file MediaCIFS.cc.

bool zypp::media::MediaCIFS::getDoesFileExist ( const Pathname & filename ) const

protectedvirtual

check if a file exists

Asserted that url is a file and not a dir.

Exceptions

MediaException

Implements zypp::media::MediaHandler.

Definition at line 401 of file MediaCIFS.cc.

bool zypp::media::MediaCIFS::isAttached ( ) const

virtual

True if media is attached.

Reimplemented from zypp::media::MediaHandler.

Definition at line 330 of file MediaCIFS.cc.

bool zypp::media::MediaCIFS::authenticate	(	AuthData &	authdata,
		bool	firstTry
	)		const

private

Todo:: need a way to pass different CredManagerOptions here

Todo:: add comma to the message for the next release

Todo:: find a way to save the url with changed username back to repoinfo or dont store urls with username (and either forbid more repos with the same url and different user, or return a set of credentials from CM and try them one by one)
