A complete seed corpus configuration with multiple sources and one destination.

• repeated SeedCorpusSource sources = 1

  A list of the seeding sources. Required.

• optional SeedCorpusDestination destination = 2

  The seeding destination. Required.

Describes the seed corpus destination location and shard filename format.

Used in: SeedCorpusConfig

• string dir_path = 1

  The output dir to which to write the generated seed corpus shard files. Required.

• string shard_rel_glob = 3

  A `dir_path`-relative glob used to generate output corpus shard filenames. Must contain a single '*' placeholder for the shard index, e.g. "corpus.*". Required.

• uint32 shard_index_digits = 4

  The minimum number of digits to use for the shard index in the shard filenames. The indices will be zero-padded. Optional: the default is to use Centipede's standard value for corpus shards.

• uint32 num_shards = 5

  The number of corpus shards to create. Required.

Describes a seed corpus source as a set of directories matching a glob in combination with a relative shard file glob searched under each of those directories.

Used in: SeedCorpusConfig

• string dir_glob = 1

  A path or a glob matching one or more dir(s) with source corpus shards. Required.

• uint32 num_recent_dirs = 2

  The number of most recent `dir_glob`-matching dirs to use. The dirs are assumed to have names that are lexicographically sorted in the order from oldest to newest. Required.

• string shard_rel_glob = 3

  A relative glob used to find corpus shards in each `dir_glob`-matching dir. Required.

• oneof sample_size

  An absolute or relative number of corpus elements to sample from all the corpus shards in all `dir_glob` matching dirs of this source. Optional: the default is to take all the elements.

  • float sampled_fraction = 4

    Sample a fraction of elements. Must be <= 1.0.

  • uint32 sampled_count = 5

    A fixed number of elements. If >= the number of elements, use all.
