'''Date unknown, copied 26 March 2007'''

+

* client: computation of duration_correction_factor was messed up. E.g. when the correct value is .5, it converges to sqrt(.5)

+

* client: tweak DCF update computation

+

* client (Unix): tweak stack-size logic, and don't bump stack size limit beyond 64MB

+

* client: fix bug where client thinks an app is running but it isn't.

+

• Basic problem: there are two layers

+

:1) process control: start/stop/suspend/resume, handle exits.

+

::files: app_*.C

+

::It owns ACTIVE_TASK::task_state

+

:2) CPU scheduling: decide what should run

+

::files: cpu_sched.C

+

::It owns ACTIVE_TASK::scheduler_state.

+

::These layers weren't cleanly separated; e.g. the CPU sched layer relied on the process control layer to set scheduler_state in some cases, and this wasn't always being done. I fixed this; the layers are now separated.

+

• Also: added new task_state value, PROCESS_QUIT_PENDING

+

* client: small tweak to DCF calculation

+

* client: comment out stack-size stuff

+

* client: print error messages if gethostbyname() fails for entries in remote_hosts.cfg

+

* MGR:

+

• changed "defect" to "stop using"

+

• changed 2006 to 2007

+

* client (Unix): removed code for SIGTSTP and SIGCONT. never got it to work, don't need anyway; handle SIGPWR.

+

* client: print message if task finishes and output file is missing
