Detailed Description

SpoolerDefinition is given by a string of the form: <spooler type>="">:<spooler description>="">

F.e: local:/srv/cvmfs/ to define a local spooler with upstream path /srv/cvmfs/

upload::SpoolerDefinition::SpoolerDefinition ( const std::string &  definition_string,
const shash::Algorithms  hash_algorithm,
const zlib::Algorithms  compression_algorithm = zlib::kZlibDefault,
const bool  generate_legacy_bulk_chunks = false,

Reads a given definition_string as described above and interprets it. If the provided string turns out to be malformed the created SpoolerDefinition object will not be valid. A user should check this after creation using IsValid().

Member Function Documentation

SpoolerDefinition upload::SpoolerDefinition::Dup2DefaultCompression ( ) const

Creates a new SpoolerDefinition based on an existing one. The new spooler has compression set to zlib, which is required for catalogs and other meta- objects.

bool upload::SpoolerDefinition::generate_legacy_bulk_chunks

If a file is chunked, clients >= 2.1.7 do not need the bulk chunk. We can force creating the bulk chunks for backwards compatibility.

unsigned int upload::SpoolerDefinition::number_of_concurrent_uploads

This is the number of concurrently open files to be uploaded. It does not, however, specify the degree of parallelism of the I/O write operations.
