- 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
