Old: heartbeat mechanism
Problem: if the client is blocked for > 30 secs
(e.g. because it takes a long time to write the state file,
of because it's stopped in a debugger)
then apps exit.
This is bad is the app doesn't checkpoint and has been
running for a long time.
New: the client passes its PID to the app.
The app periodically (10 sec) checks that the process still exists.
Notes:
- For backward compatibility (e.g. new API w/ old client,
or vice versa) the client still sends heartbeats,
and the API checks heartbeats if the client doesn't pass a PID.
- The new mechanism works only if the client's PID isn't assigned
to a new process within 10 secs of the client exiting.
Windows 2000 reuses PIDs immediately, so check for Win2K
and don't use this mechanism if so.
TODO: For Unix multithread apps,
critical sections aren't currently being enforced.
Need to fix this by masking signals.
svn path=/trunk/boinc/; revision=26147
Tells multicore apps how many cores to use.
The --nthreads command line arg to the app is now deprecated
though we'll keep it around for the time being.

says whether the client is using account-based sandboxing.
Needed by vboxwrapper.
- web: don't show authenticator in Your Account page.
The problem with authenticators is that if a bad guys gets yours,
they can log in to your account even if you change your password.
Eventually we should not use them at all
(i.e. in cookies and sent to client).
- make_project: copy python stuff (e.g. bin/start) for web-only projects;
generate appropriate project.readme file for web-only projects.

- Fix build problems on Mac OS X using autotools
- Consistently use #if HAVE_X for platform checks,
rather than #ifdef HAVE_X or #if defined(HAVE_X)
- In Unix build, make lots of compiler checks standard
- Fix some compile warnings
From Matt Arsenault.
Note: there are now lots of compile warnings in clientgui/ on Unix,
mostly in WxWidgets code

- scheduler: add max_download_urls_per_file config option
(to limit the length of workunit.xml_doc,
which is currently capped at 64KB).
From Bernd.

This exits the app with status zero and no finish file,
so the client will restart it.
It creates a file "temporary_exit" containing dt.
The (new) client reads this file and will postpone
scheduling the job again for dt seconds.
Old clients will treat it as a premature exit,
and potentially try to reschedule the job immediately.
This function is intended for GPU applications that
fail to allocate GPU RAM,
presumably because a non-GPU application has it allocated.
We don't want the job to fail,
and we want to wait for a while before trying the allocation again.

- scheduler: fix bug in adaptive replication:
if send an unreplicated job to untrusted host,
set both wu.target_nresults and wu.min_quorum to app.target_nresults.

This supports apps that can do variable amounts of computing;
they can boinc_finish() if their deadline is near.
Rom: please back-port.

- update_versions: use __ (not :) as separator for plan class
- client: add plan_class to APP_VERSION;
an app version is now identified by platform/version/plan_class
- client CPU scheduler: don't assume apps use 1 CPU
- client: add avg_ncpus, max_cpus, flops, cmdline to RESULT
- scheduler: implement app planning scheme
Other changes:
- client: if symlink() fails, make a XML soft link instead
(for Unix running off a FAT32 FS)
- client: don't accept nonpositive resource share from AMS
- daemons and DB: check for error returns from enumerations,
and exit if so. Thus, if the MySQL server goes down,
all the daemons will soon exit.
The cron script will restart them every 5 min,
so when the DB server comes back up so will the project.
- web: show empty max CPU % as ---
- API: get rid of all_threads_cpu_time option (always the case now)

This is for debugging apps (currently works only in Unix).
What it does: when running an app,
the client does everything except actually fork/exec the app,
i.e. it sets up the slot dir, creates shared mem segment etc.
It then continues as if the app were actually running,
and you can then manually run your app under a debugger
in the slot directory.
Note: the client won't notice the termination of your app.
- API, Unix: in situations where the timer thread wants to exit
(e.g. it notices a missing heartbeat).
don't directly call boinc_exit(),
since this touches data structures that the worker thread
may be using concurrently.
Instead, set a flag telling the worker thread to call boinc_exit()
(which it will do from its signal handler)
This is an attempt to fix problems reported by Bernd;
I haven't tested it.
- scheduler: add config flag for uploading usage data
- web: show account key and weak account key on user page
- added some code for multithread support (not finished)

removed references to "graphics thread"
removed HANDLE timer_quit_event
removed enable_heartbeat/disable_heartbeat messages
(not sure what the ideas was, but no longer exists)
removed heartbeat_active flag (use options.check_heartbeat instead)
read heartbeat-channel messages even if heartbeat disabled
(since we use that channel for WSS messages too)
- client: remove ACTIVE_TASK::thread_handle (not used)

- Added svn:executable to tools/watch_tcp because it has a shebang.
