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)

This was because SIGALRM always interrupts sleep()
and keeps boinc_sleep() stuck in its while loop.
Solution: change boinc_sleep() so that it works even if
rapid signals (e.g. interval timer) are happening
- API: remove deprecated graphics files from Makefile.
Old-style graphics are no longer supported.
- web: add empty show_user_donations_private() to donations.inc

Previously it was called from both timer and worker thread,
with no synchronization. Bad.
boinc_finish(): sleep for 2 seconds, enough to ensure that
the timer thread sends the final messages.
- API: a compile flag GETRUSAGE_IN_TIMER_THREAD selects
how to get CPU time; by default set only for Mac OS X
- scheduler: cap #CPUs scaling for <max_wus_per_host> at 8

(since calling it from worker thread causes crashes).
On Linux, call getrusage() from the worker thread
(since calling it from the timer thread returns zero on some systems).
- stripcharts: make it work even if Perl is not in path (from Eric Myers)
svn path=/trunk/boinc/; revision=14462
calls getrusage() in a signal handler to find its CPU time.
Apparently there are some kernels and/or thread libraries
where getrusage() does NOT return the total CPU time of
all threads in the process,
so in these cases calling it from the timer thread doesn't work.
This was originally changed because of concerns that
calling getrusage() in a signal handler was dangerous;
we'll see if any problems re-emerge.
The alternative of reading /proc/PID/stats doesn't seem viable;
format may not be standardized.
svn path=/trunk/boinc/; revision=14433
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)

this limits the length of the generated string
~12 chars even for big/small numbers.
Also reduce buffer size from 8000 to 256;
default thread stack size might not accommodate 8000 + extra.
svn path=/trunk/boinc/; revision=14112
use strlcat() instead of strcat().
Einstein@home has seen some SEGVs in this function.
I suspect that it's getting 1e304-type values
(why? possible bugs in getrusage-related code, still)
and that these cause long strings that overflow the message buffer.

not the worker signal handler.
There's no reason to call it from the signal handler -
it returns the CPU for the entire process, not the calling thread.
And it may be asynch-signal-handler-unsafe.
- API: comment out checks for bad CPU times.
I don't think this is needed now, and in some cases it's wrong
(multi-threaded apps can accumulate CPU faster than real time)
- API, Unix: in boinc_calling_thread_cpu_time(), don't retry getrusage().
- Bossa: switch to better class structure (suggested by Nicolas Alvarez).
Haven't switched to mysqli yet, but will later.
Also various other Bossa fixes
svn path=/trunk/boinc/; revision=13855
- check for infinity/NaN
- check for CPU time decreasing
- check for CPU time increasing faster than real time
... and deal with each of these in a hopefully reasonable way
svn path=/trunk/boinc/; revision=13847
and access to worker_thread_ru.
This was being used in the worker signal handler,
which is bad because pthread_mutex_lock() can allocate memory.
I don't think this matters; at worst we might get
CPU times off by < 1 sec.

at most one regular and one full-screen graphics window can be open,
and a "hide" message kills the full-screen window if one exists,
else a regular window.
Keep track of the PIDs separately for regular and full-screen.
Also, don't send a "hide" ack if we don't do graphics.

in a V6 app (and launching/killing the graphics app)
- API: start timer thread even if in standalone mode
(needed to get timer callbacks for V6 graphics)
- API: remove BOINCSetForegroundWindow stuff
- API: call DestroyWindow instead of boinc_exit() in WM_CLOSE.
boinc_exit() is the wrong thing to call - e.g. it tries to delete
the lock file, resulting in a 5-sec delay on exit
svn path=/trunk/boinc/; revision=13679
(deciding which app to use, implementing blanking interval, etc.)
This logic is all now in the screensaver itself.
- GUI RPC: removed get/set screensaver mode RPCs
- API: added a "backwards_compatible_graphics" flag to BOINC_OPTIONS.
V6 apps should set this.
If set, the runtime library checks for graphics messages
from the client, and launches/kills the graphics app (if any).
The app will then work graphically with pre-V6 clients.
- removed some old files

update_versions to add version 6 apps.
It looks for API_VERSION string in main executable,
adds the API version to the app_version XML,
and sets min_core_version to 6 for version 6+ apps
- API: include API_VERSION string
- convert tabs to spaces here and there
- scheduler: parse unused elements in <net_stats>
- ops/show_log.php: if no URL args, just show form (fixes#415)
- client: parse and store api_version (not used yet)
