◆ Calc() [1/2]

virtual int XrdCksManOss::Calc	(	const char *	Lfn,
		time_t &	MTime,
		XrdCksCalc *	CksObj
	)

protectedvirtual

Reimplemented from XrdCksManager.

◆ Calc() [2/2]

virtual int XrdCksManOss::Calc	(	const char *	Pfn,
		XrdCksData &	Cks,
		int	doSet = `1`
	)

virtual

Calculate a new checksum for a physical file using the checksum algorithm named in the Cks parameter.

Parameters

Pfn	The physical name of the file to be checksumed.
Cks	For input, it specifies the checksum algorithm to be used. For output, the checksum value is returned upon success.
doSet	When true, the new value must replace any existing value in the Pfn's extended file attributes.

Returns: Success: zero with Cks structure holding the checksum value. Failure: -errno (see significant error numbers below).

Reimplemented from XrdCksManager.

◆ Del()

virtual int XrdCksManOss::Del	(	const char *	Pfn,
		XrdCksData &	Cks
	)

virtual

Delete the checksum from the Pfn's xattrs.

Returns: Success: 0 Failure: -errno (see significant error numbers below).

Reimplemented from XrdCksManager.

◆ Get()

virtual int XrdCksManOss::Get	(	const char *	Pfn,
		XrdCksData &	Cks
	)

virtual

Retreive the checksum from the Pfn's xattrs and return it and indicate whether or not it is stale (i.e. the file modification has changed or the name and length are not the expected values).

Parameters

Pfn	The physical name of the file to be checksumed.
Cks	For input, it specifies the checksum type to return. For output, the checksum value is returned upon success.

Returns: Success: The length of the binary checksum in the Cks structure. Failure: -errno (see significant error numbers below).

Reimplemented from XrdCksManager.

◆ List()

virtual char * XrdCksManOss::List	(	const char *	Pfn,
		char *	Buff,
		int	Blen,
		char	Sep = `' '`
	)

virtual

List names of the checksums associated with a Pfn or all supported ones.

Parameters

Pfn	The name of the physical file whose checksum names are to be returned. When Pfn is null, return all supported checksum algorithm names.
Buff	Points to a buffer, at least 64 bytes in length, to hold a "Sep" separated list of checksum names.
Blen	The length of the buffer.
Sep	The separation character to be used between adjacent names.

Returns: Success: Pointer to Buff holding at least one checksum name. Failure: A nil pointer is returned.

Reimplemented from XrdCksManager.

◆ ModTime()

virtual int XrdCksManOss::ModTime	(	const char *	Pfn,
		time_t &	MTime
	)

protectedvirtual

Reimplemented from XrdCksManager.

◆ Set()

virtual int XrdCksManOss::Set	(	const char *	Pfn,
		XrdCksData &	Cks,
		int	myTime = `0`
	)

virtual

Set a file's checksum in the extended attributes along with the file's mtime and the time of setting.

Parameters

Pfn	The physical name of the file to be set.
Cks	Specifies the checksum name and value.
myTime	When true then the fmTime and gmTime in the Cks structure are to be used; as opposed to the current time.

Returns: Success: zero is returned. Failure: -errno (see significant error numbers below).

Reimplemented from XrdCksManager.

◆ Ver()

virtual int XrdCksManOss::Ver	(	const char *	Pfn,
		XrdCksData &	Cks
	)

virtual

Retreive the checksum from the Pfn's xattrs and compare it to the supplied checksum. If the checksum is not available or is stale, a new checksum is calculated and written to the extended attributes.

Parameters

Pfn	The physical name of the file to be verified.
Cks	Specifies the checksum name and value.

Returns: Success: True Failure: False (the checksums do not match) or -errno indicating that verification could not be performed (see significant error numbers below).

Reimplemented from XrdCksManager.
