- Full support for UNIX-style operations (
ls,touch,mkdir,cp,mv,rm) locally and via the SSH/SCP protocols. - Support for all of these operations except
touchvia GRIDFTP and WEBDAV. - GSI/certificate-based authentication/authorization (SSH and GRIDFTP).
- Automatic one-hop handling of third-party transfers over mixed protocols (e.g., SCP on host A to GRIDFTP on host B).
- Two ways of achieving file transfer or deletion:
- By specifying exact locations/paths;
- By scanning or listing.
- Fully recursive pattern-based scanning (using the '*' and '**' wildcard characters; see UriPattern).
- All operations configured (using the available settings appropriate to the given protocol) via a general-purpose configuration object.
- All GRIDFTP options available in the
jglobuslibrary exposed for configurability; in particular, optimization settings such as:- TCP buffer size;
- setting active mode on the target.
- Automated support for both LIST and MLST/MLSD (GRIDFTP); options for forcing existence checking through the LIST command.
- Automated staging of files from UNITREE tape archive using GRIDFTP (= MSSFTP).
- Full access (i.e., by non-Trebuchet-related code), if so desired, to source and target paths during and after operations.
- Thread-pooled parallel copy operations.
- Automated use of multiple GRIDFTP connections for a given endpoint, when available, for non-striped operations.
- Fail-over and retry capabilities on a file-by-file basis.
- Flexibility in the kind and number of events the user can opt choose to receive.
