(in config.xml) to include DB name, user, and password.
- back end: add read-only replica info to SCHED_CONFIG,
so that C++ programs can use the replica
(currently only PHP code can use it)
- db_dump: use the read-only DB replica if it exists.

- daily quota mechanism
- reliable mechanism (accelerated retries)
- "trusted" mechanism (adaptive replication)
- scheduler: enforce host scale probation only for apps with
host_scale_check set.
- validator: do scale probation on invalid results
(need this in addition to error and timeout cases)
- feeder: update app version scales every 10 min, not 10 sec
- back-end apps: support --foo as well as -foo for options
Notes:
- If you have, say, cuda, cuda23 and cuda_fermi plan classes,
a host will have separate quotas for each one.
That means it could error out on 100 jobs for cuda_fermi,
and when its quota goes to zero,
error out on 100 jobs for cuda23, etc.
This is intentional; there may be cases where one version
works but not the others.
- host.error_rate and host.max_results_day are deprecated
TODO:
- the values in the app table for limits on jobs in progress etc.
should override rather than config.xml.
Implementation notes:
scheduler:
process_request():
read all host_app_versions for host at start;
Compute "reliable" and "trusted" for each one.
write modified records at end
get_app_version():
add "reliable_only" arg; if set, use only reliable versions
skip over-quota versions
Multi-pass scheduling: if have at least one reliable version,
do a pass for jobs that need reliable,
and use only reliable versions.
Then clear best_app_versions cache.
Score-based scheduling: for need-reliable jobs,
it will pick the fastest version,
then give a score bonus if that version happens to be reliable.
When get back a successful result from client:
increase daily quota
When get back an error result from client:
impose scale probation
decrease daily quota if not aborted
Validator:
when handling a WU, create a vector of HOST_APP_VERSION
parallel to vector of RESULT.
Pass it to assign_credit_set().
Make copies of originals so we can update only modified ones
update HOST_APP_VERSION error rates
Transitioner:
decrease quota on timeout

- client (Unix): if client crashes while benchmark processes are going,
make sure they detect this and exit.
- back-end programs: remove hardwired assumptions about
what directory they run in, and hence where config.xml is.
E.g., daemons look for it in "..", others expect it in current dir.
New approach: all the programs look for the project dir as follows:
1) the environment var BOINC_PROJECT_DIR, if defined
2) the current dir, if config.xml is there.
3) else ".."
This means you can run programs in either proj/bin/ or proj/,
or (using BOINC_PROJECT_DIR) you can keep executables
outside of the project dir.

put a textual summary of them in host.serialnum (currently unused)
- web: show coprocs on host detail page
- db_dump: include coproc info in host XML
