Detailed Description

This class allows to handle xrd http checksum algorithm selection based on what the user provided as a digest

Member Function Documentation

configure()

void XrdHttpChecksumHandler::configure ( const char * csList )

inline

Configure this handler.

Exceptions

runtime_exception

if no algorithm in the csList is compatible with HTTP

Parameters

csList

the list coming from the server configuration. Should be under the format 0:adler32,1:sha512

Definition at line 97 of file XrdHttpChecksumHandler.hh.

{ pImpl.configure(csList); }

getChecksumToRunWantDigest()

XrdHttpChecksumRawPtr XrdHttpChecksumHandler::getChecksumToRunWantDigest ( const std::string & wantDigest ) const

inline

Returns the checksum to run from the user "Want-Digest" provided string

Parameters

wantDigest

the digest string under the format "sha-512,sha-256;q=0.8,sha;q=0.6,md5;q=0.4,adler32;q=0.2"

Returns

the checksum to run depending on the userDigest provided string The logic behind it is simple: returns the first userDigest provided that matches the one configured. If none is matched, the first algorithm configured on the server side will be returned. If no HTTP-IANA compatible checksum algorithm has been configured or NO checksum algorithm have been configured, nullptr will be returned.

{ return pImpl.getChecksumToRunWantDigest(wantDigest); }

getChecksumToRunWantReprDigest()

XrdHttpChecksumRawPtr XrdHttpChecksumHandler::getChecksumToRunWantReprDigest ( const std::map< std::string, uint8_t > & wantReprDigest ) const

inline

Returns the checksum to run from the user "Want-Repr-Digest" header provided values (already parsed in a map <digestName, preference>)

Parameters

wantReprDigest

the map containing the user want-repr-digest values

Returns

the checksum to run depending on the map in parameter. If the map contains checksums that are not configured on the server, it will return the first configured checksum on the server. If multiple configured checksums are configured and multiple checksums are requested, it will return the one with the highest preference. If same preference, the checksum returned will be the first one of the alphabetically ordered configured checksum

{ return pImpl.getChecksumToRunWantReprDigest(wantReprDigest); }

getNonIANAConfiguredCksums()

const std::vector< std::string > & XrdHttpChecksumHandler::getNonIANAConfiguredCksums ( ) const

inline

Returns the checksums that are incompatible with HTTP --> the ones that we do not know whether the result should be base64 encoded or not

Definition at line 122 of file XrdHttpChecksumHandler.hh.

{ return pImpl.getNonIANAConfiguredCksums(); }
