The batch query call used by Condor (query_batch_set(), in the C++ API)
returned info about all the jobs in the set of batches,
even those that hadn't changed.
This is potentially inefficient - a query might return info
about 10,000 jobs, only a few (or none) of which have changed state
since the last call.
Solution: add a "min_mod_time" parameter to the call.
Only jobs that have changed state since that time are reported.
Also, add a "server_time" field to the return,
giving the current time on the server
(in case there's clock skew between client and server)
Also, fix some text scrambling introduced in previous checkin;
there must have been a gremlin in my vim.
- Batches now have optional "expire time".
If this time passes and the batch is not retired, abort and retire it.
- Add script "expire_batches" which enforces the above.
Run it as a periodic task.
- Add a web RPC for setting the expire time of a batch
(it can be changed multiple times)
- Add a C++ interface for this RPC
- Add a BOINC_SET_LEASE command to the BOINC GAHP
("lease" is Condor term for expire time)
BOINC_QUERY_BATCHES now prints, for each queried batch,
a count of jobs followed by the jobs
BOINC_ABORT_JOBS takes a list of jobs, which may belong to different batches.
The handler for this looks up the batches and makes sure
the jobs belong to the user.
- XML parser: for parse_string(), malloc the 256KB buffer instead of
allocating it on the stack; the latter crashes threads with 32KB stacks.
However, do the malloc() only if we've actually seen the start tag
(this required a bit of code shuffle).
- BOINC GAHP: escape spaces in error msgs
- remote job submission:
- prefix error messages with "BOINC server:"
so higher levels can tell where the error is coming from
- "get templates" RPC can take job name instead of app name
- Condor interface
- add BOINC_SELECT_PROJECT function
- BOINC_SUBMIT no longer has info about output files
- Change BOINC_FETCH_OUTPUT semantics
- change "query_batch" to "query_batches"; allow multiple batches
- add "ping server" web RPC and GAHP function
- change BoincDb::get() so that it generates XML error message if needed
- add Web RPC for querying a completed job (returns status,
stderr out, run times, etc.)
- support Jaime's changes to GAHP protocol
- support for zipped output files
