Certain capabilities, such as restarting operations and inspecting the binary "cache" files, are also available from the command-line. There are plans to provide sometime in the near future an Eclipse-based RCP Trebuchet client for easy management of file transfers across multiple hosts.
Features
The following are some of the more salient features offered by the Trebuchet library/tasks:
- 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).
- One-hop third-party transfers over mixed protocols (e.g., SCP on host A to GRIDFTP on host B) handled automatically.
- 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).
- All operations can be custom configured (using the appropriate settings) via a general-purpose configuration object.
- All GRIDFTP options available in the
jglobuslibrary are 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.
- Full access to source and target paths before and after operations.
- Thread-pooled parallel copy operations.
- Automated use of multiple GRIDFTP connections for a given endpoint (as specified by the SPAS command) 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 to receive.
