CogVM source as per VMMaker.oscog-eem.296/r2732.
Make the Production/Debug/Assert distinction static so one can find it with strings - vm. Add an ident for the ITIMER_HEARTBEAT linux VMs.
Fix bug in eden filling/object overwrite checking. must use unsigned vars in the fill loop.
Add a plugin to support the VMProfiler on linux (now Steve Rees has told us how to get proper thread priorities on newer linuxes).
Replace broken primitiveUtcWithOffset with a version that works. Cast primitiveUtcWithOffset in terms of a new ioLocalSecondsOffset.
Add stricter checking code to OSProcessPlugins.
Add SqueakSSL plugin to nsvm plugins.
Change -version output to print if a Production, Debug or Assert VM.
Add some error checking to the UnixOSProcessPlugin's forkAndExecInDirectory prim. Eliminate some compiler warnings in the plugin.
Eliminate some excessive use of push/popRemappableOop[:] in the SocketPlugin.
Fix numberic option parsing in sqSocketSetOptions... (quite possibly the longest C function name I've ever seen). The old code only supported 1-digit length values, so setsockopt(SO_SNDBUF, 4096 didn't do what was expected at all (attempted to set the buffer size to 909717556, which is little-endian ascii for '4096', '4096' asByteArray unsignedLongAt: 1 => 909717556).
Occasionally bizarre interactions cause the heartbeat's interval timer to disable. e.g. on CentOS linux when using PAM to authenticate, a failing authen- tication sequence disables the interval timer, for reasons unknown (setting a breakpoint in setitimer doesn't show an actual call). So a work around is to check the timer as a side-effect of ioRelinquishProcessorForMicroseconds.
Add Callback LIFO ordering support to the new-style Callback return primitives to the IA32ABI Aline plugins. Fix some compiler warnings there-in.
Improve the debug message printing in sqUnixExternalPrims.c so it prints line numbers. -- best, Eliot
