On systems with comparatively slow disk subsystems, the I/O can become saturated. This leads the Linux Kernel on guest OS's dumping out warning messages to the console of failure to write data to disk. Since the device drivers are timer sensitive we will boost the priority of the process to boost its disk I/O requests above the other disk I/O of science applications. Science applications themselves generally don't have timeouts when checkpointing and the like.
* Move the windows_format_error_string function to win_util.cpp, .h instead of it being scattered between util.h and str_util.cpp.
* Convert the Windows error string into UTF8 before allowing it to be used by the caller
* Remove windows_error_string from library
- Win process control (affects API and wrapper):
Since Win doesn't have an API for process suspend/resume,
we were suspending processes by
1) enumerating all the threads in the system (typically several thousand)
2) suspending those belonging to the given process
The problem: for each thread, the code was calling a function
in diagnostics_win.cpp to see if the thread was exempted from suspension.
This check (which is unnecessary anyway if we're suspending another process)
was surrounded by a semaphore acquire/release.
The result: performance problems.
It could take a minute to suspend the threads.
Solution:
1) do the check for exemption only if we're suspending threads
in our own process (i.e. from the API)
2) if we're suspending multiple processes, enumerate the threads
only once, and see if each one belongs to any of the processes
3) have the wrapper elevate itself to normal priority.
Otherwise it can get preempted for long periods,
sometimes in the middle of scanning the threads.
Note: post-9x versions of Win have a process group API that includes suspend/resume.
We'll switch to this soon.

CODING STYLE LAW (minimal inclusion principle):
If foo.cpp requires <blah.h>,
#include <blah.h> in foo.cpp, NOT foo.h

- 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

of the performance of an app version on a host.
It will then stop using that app version,
so the estimate never has a chance to converge to its correct value.
Fix: multiply by a random factor (mean 1, stddev .1)
when comparing the FLOPS estimates of app versions.

My change of 1 Oct ([22440]) required that such jobs
be processed with 64-bit apps,
on the assumption that 32-bit apps have a 2 GB user address space limit.
However, it turns out this limit applies only to Windows
(kernel and user mode share the 4GB address space; each gets half).
On Linux, the split is 3GB user / 1 GB kernel.
On Mac OS X, user mode and kernel mode have separate address spaces,
each of them 4 GB.

- scheduler: add support for the GCL simulator,
which uses special versions of backend programs
that use virtual time,
and that wait for signals instead of sleep()ing.
To compile:
make clean

The problem was that there's a lot of extra stuff needed
for running apps on Windows (e.g. related to sandboxing).
This needed to be a new function.

block for applications launched using the 'boinc_project' account.
Windows contains environment variables that describe username,
domain name, profile directory and even logon server.
- client: correctly parse domain name information from the
client_auth.xml file when a different account is used for
'boinc_master'.
- SCR/MGR: Add two API's to adjust the ACLs on the current users
desktop and windowstation so that graphics applications can
properly create controls and dialogs for applications
launched using 'boinc_project'.

Win2k requires any user account that is going to attempt
to logon as another account to have admin privs.
- WINSETUP: Give 'boinc_project' the right to be able to
logon as a service, we denied the right to logon
interactively.
- WINSETUP: Disable the 'failed to shutdown BOINC service'
dialog box.
- CC: Use the client_auth.xml file if present to launch
boinc applications as boinc_project if it exists.
- LIB: Use the client_auth.xml file if present to launch
boinc graphics applications as boinc_project if it
exists.

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

- move client sandbox-specific code to a new file, sandbox.C
- remove g_use_sandbox from util.C; move to MainDocument.cpp (manager)
and sandbox.C (client)
- don't declare check_security() in util.h; it's not in util.C
- don't call remove_project_owned_file_or_dir() in
boinc_delete_file_aux() or boinc_rmdir();
rather, at the points in the client that delete
dirs that are usually owned by boinc_projects,
call remove_project_owned_file_or_dir() first,
then clean_out_dir().
- rename boinc_exec() to switcher_exec() and move it to sandbox.C
Note: this change was sparked by needing to remove a call to getgrnam()
from boinclib, to avoid requiring the same version of glibc
on both compile and target hosts

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.

- client: parse <cpid_time> in scheduler reply;
add cpid_time field to PROJECT.
This defaults to the user_create_time.
In deciding which CPID to send in a scheduler request,
use the one with oldest cpid_time (not user_create_time).
This is the client half of fixing a bug that causes
CPID to flip/flop between to values in a certain case.
