Detailed Description

Manages access to the 'physical' media, e.g CDROM drives, Disk volumes, directory trees, etc, using Media Access Url's.

Note: The MediaManager class is just an envelope around an inner singleton like implementation.
That is, you can create as many managers as you want, also temporary in a function call.
But don't declare static MediaManager instances, unless you want to force (mutex) initialization order problems!

Media Access Url

The MediaManager uses several media access handlers (backends), that can be specified by a Media Access URL in its open() method.

All URLs may contain following query parameters, that are reserved by the Source classes and unused/ignored by the media manager:

alias: A source specific media alias string.

Currently, following access handlers (backends) are implemented:

MediaCD - CD/DVD drives (cd, dvd)

The access handler for media on CD / DVD drives.

Scheme:
- cd: Requires a drive supporting CD media.
- dvd: Prefers a drive supporting DVD media.
Examples:
"cd:/"

"cd:/?devices=/dev/hda,/dev/hdb"

"cd:/subdir?devices=/dev/hda,/dev/hdb"

"dvd:/"

"dvd:/?devices=/dev/hda,/dev/hdb"

"dvd:/subdir?devices=/dev/hda,/dev/hdb"

Note: You can use either "dvd:/" (just path, no authority) or "dvd:///" (path and empty authority).
Query parameters:
- devices: Optional parameter, containing a comma separated list of block device names to use, e.g.: "/dev/sr0,/dev/sr1".
  The device names will be verified using a HAL query. If one of the provided devices is not usable (not a block device, or does not support required media type), an exception is thrown.
  If the devices parameter is not provided (or empty), all avaliable CD/DVD drives 'detected' using a HAL query. The preferred drive (used as first drive) is the drive pointed to by the symlink "/dev/dvd" ("dvd" scheme only) or "/dev/cdrom".
Authority: A non-empty authority URL component (e.g. containing a host name) is not allowed.
Path name: Mandatory URL component, that specifies a subdirectory on the CD/DVD, where the desired files are located.

MediaDISK - HD disk volumes (hd)

The access handler for media on a disk volume (partition).

Scheme:
- hd
Examples:
"hd:/?device=/dev/hda1"

"hd:/subdir?device=/dev/sda1"

"hd:/subdir?device=/dev/sda1&filesystem=reiserfs"

Note: You can use either "hd:/" (just path, no authority) or "hd:///" (path and empty authority).
Query parameters:
- device: Mandatory parameter specifying the name of the block device of the partition to mount.
- filesystem: The name of the filesystem. Defaults to "auto".
Authority: A non-empty authority URL component is not allowed.
Path name: Mandatory URL component, that specifies a subdirectory on the disk partition, where the desired files are located.

MediaDIR - Local directory tree (dir, file)

The access handler to media stored in a local directory tree.

Scheme:
- dir
- file
Examples:
"dir:/directory/name"

"file:/directory/name"
Query parameters: none
Authority: A non-empty authority URL component (e.g. containing a host name) is not allowed.
Path name: Mandatory URL component, that specifies a directory, where the desired files are located.

MediaISO - Loopback ISO images (iso)

The access handler for media in a ISO image (loopback mount).

Scheme:
- iso
Examples:
"iso:/?iso=/path/to/CD1.iso"

"iso:/?iso=CD1.iso&url=dir:/path/to"

"iso:/?iso=CD1.iso&url=nfs://server/path/to/media"

"iso:/?iso=CD1.iso&url=hd:/?device=/dev/hda"

"iso:/subdir?iso=DVD1.iso&url=nfs://nfs-server/directory&mnt=/nfs/attach/point&filesystem=udf"
Query parameters:
- iso: Mandatory parameter specifying the name of the iso file.
  If the url parameter is missed, the iso parameter has to contain an absolute iso file name.
- url: Optional parameter specifying the URL to the directory containing the iso file.
  The supported URL schemes are: hd, dir, file, nfs, nfs4, smb, cifs.
- mnt: Optional parameter specifying the prefered attach point for the source media url.
- filesystem: Optional name of the filesystem used in the iso file. Defaults to "auto".
Authority: A non-empty authority URL component is not allowed.
Path name: Mandatory URL component, that specifies a subdirectory inside of the iso file, where the desired files are located.

MediaNFS - NFS directory tree (nfs)

The access handler for media on NFS exported directory tree.

Scheme:
- nfs
- nfs
Examples:
"nfs://nfs-server/exported/path"

"nfs://nfs-server/exported/path?mountoptions=ro"

"nfs://nfs-server/exported/path&type=nfs4"

"nfs4://nfs-server/exported/path"
Query parameters:
- mountoptions: The mount options separated by comma ','. Default is the "ro" option.
- type=nfs4: Whether to mount as nfs4. This is the default for scheme nfs4.

Authority: The authority component has to provide a hostname. Username, password and port are currently ignored.

Path name: Mandatory URL component, that specifies the exported (sub-)directory on the NFS server, where the desired files are located.

MediaCIFS - CIFS/SMB directory tree (cifs, smb)

The access handler for media in a CIFS/SMB shared directory tree.

Scheme:
- cifs
- smb
Examples:
"cifs://servername/share/path/on/the/share"

"cifs://username:passwd@servername/share/path/on/the/share?mountoptions=ro"

"cifs://username:passwd@servername/share/path/on/the/share?mountoptions=noguest"

"smb://servername/share/path/on/the/share"

"smb://username:passwd@servername/share/path/on/the/share?mountoptions=ro"

Note: There is no difference between cifs and smb scheme (any more). In both cases the 'cifs' filesystem is used.
Query parameters:
- mountoptions: The mount options separated by a comma ','. Default are the "ro" and "guest" options. Specify "noguest" to turn off "guest". This is necessary if Samba is configured to reject guest connections.
- workgroup or domain: The name of the workgroup.
- username: Alternative username to username in URL authority.
- password: Alternative password to password in URL authority.
- user: Alternative username (cifs specific variant)
- pass: Alternative password (cifs specific variant)
Authority: The authority component has to provide a hostname. Optionally also a username and password.
Path name: Mandatory URL component, that specifies the share name with optional subdirectory, where the desired files are located.

MediaCurl - FTP/HTTP directory tree (ftp, tftp, http, https)

The access handler to media directory tree on a ftp/http server.

Scheme:
- ftp
- tftp
- http
- https
Examples:
"ftp://server/relative/path/to/media/dir"

"ftp://server/%2fabsolute/path/to/media/dir"

"ftp://user:pass@server/path/to/media/dir"

"ftp://user:pass@server/%2f/home/user/path/to/media/dir"

"http://server/path/on/server"

"http://user:pass@server/path"

"https://user:pass@server/path?proxy=foo&proxyuser=me&proxypass=pw"

Note: The "ftp" url scheme supports absolute and relative paths to the default ftp server directory (RFC1738, Section 3.2.2).
To use an absolute path, you have to prepend the path with an additional slash, what results in a "/%2f" combination (second "/" encoded to "%2f") at the begin of the URL path.
This is important, especially in user authenticated ftp, where the users home is usually the default directory of the server (except when the server chroots into the users home directory).
For example, if the user "user" has a home directory "/home/user", you can use either an URL with a relative path to the home directory "ftp://user:pass@server/path/to/media" or the absolute path "ftp://user:pass@server/%2fhome/user/path/to/media" – both URLs points to the same directory on the server.
Query parameters:
- cookies: Turn off using cookies by setting it to "0" (or false, no, off).
- proxy: A proxy hostname or hostname and port separated by ':'. Setting the hostname to 'none' explicitly disables the use of a proxy even if configured in /etc/sysconfig/proxy or the environment.
- proxyport: Alternative way to provide the proxy port.
- proxyuser: The proxy username.
- proxypass: The proxy password.
- ssl_capath: The absolute CA directory to use, default is /etc/ssl/certs.
- ssl_verify: Flag to modify the ssl verify behaviour. Valid values are: 'yes', 'no' and a comma separated list of 'host' and 'peer' flags.
  - 'no': disables ssl verify
  - 'yes': enables ssl verify, this is the default and is equivalent to 'host,peer'.
  - 'host': The server is considered the intended one, when the 'Common Name' field or a 'Subject Alternate Name' field in the certificate matches the host name in the URL.
  - 'peer': Verifies whether the certificate provided by the server is authentic against the chain of digital signatures found in ssl_capath.
- ssl_clientcert Path to the ssl client certificate for authentication to a repo (CURLOPT_SSLCERT).
- ssl_clientkey Path to the ssl client key for authentication to a repo (CURLOPT_SSLKEY).
- timeout: Transfer timeout in seconds between 0 and 3600, 0 disables the timeout, default timeout is 180 seconds.
- auth: A comma separated list of http authentication method names to use: 'basic', 'digest', 'ntlm', 'negotiate', 'spnego', 'gssnego'. Note, that this list depends on the list of methods supported by the curl library.
- mediahandler: Set the mediahandler for this url Valid values are: 'curl', 'multicurl'
Authority: The authority component has to provide a hostname. Optionally also a username and password. In case of the 'ftp' scheme, username and password defaults to 'anonymous' and 'yast2@'.
Path name: Mandatory URL component, that specifies the path name on the server, where the desired files are located.

Proxy settings: If no proxy settings are present in tha URLs query parameters, the media handler reads the system wide proxy settings from the /etc/sysconfig/proxy file. If a proxy setting was present, but the proxy password not, it attempts to read the proxy-user variable from the ~/.curlrc (/root/.curlrc) file.
If no proxy setting was present, then libzypp does not pass any proxy settings to curl, but curl fallbacks to use the content of the http_proxy, ftp_proxy, etc environment variables.

MediaPlugin - custom media handler

Media access is delegated to a script located in the libzypp media plugin directory. The URLs query options are translated into commandline arguments passed to the script.

Scheme:
- plugin
Examples:
"plugin:script?loptv=lvalue&v=optv&lopt=&o&=foo"

\__________/ \____/ \___/ | \_/

__________/__ ____/_ _|_ \ \___

/ \ / \ / \ /\ / \

script --loptv "lvalue" -v "optv" --lopt -o -- foo
Query parameters:
- The URLs query options are translated into commandline arguments passed to the script.
- Note: No option may appear twice, as the (option,value) pairs are stored in a hash.
- Note: The order in which the query options are passes to the script is arbitrary, except for an option with an empty key, which is translated into '– value' and passed as final option.
- 'c[=[value]]' ist passed as '-c [value]'
- 'word[=[value]]' ist passed as '–word [value]'
- '[=value]' ist passed as last args as '– [value]'
script<->libzypp communication:
- to be documented.
