Hi Richard,
Here is V3, the main changes are:
1) Can set each directory's threshold separately
2) Can choose the action when the disk space is running low:
a) Warn
b) No new task
c) Abort
3) Change the time interval to disk space(or inode) interval, the reason
is:
If we use the time interval, then we need a timer, and the timer
should be actived when the runqueue starts, and it should combine
closely with the runqueue since it it needs controll the task(no new
task), and the timer should in the subprocess, otherewise it would
block the runqueue, it seems hard to terminate to pass the Ctrl-C
to the subprocess since the Ctrl-C is captured by the ui, so I change
the time interval to the disk space(or inode) interval, this seems
more reasonable than the time interval, it would only warn when the
disk space reduce more than the interval, for example, if the interval
is 10M, it would warn when the space is lower than the threshold, and
warn again when the space reduce more than 10M.
4) The testing result: (The action would be executed when the space or inode
is lower than the threshold):
a) When the space is running low:
BB_DISKMON_DIRS = "${TMPDIR},130G,20M"
i) BB_DISKMON_ACTION = "WARN"
WARNING: The free space of /dev/sdb4 is running low (119.700GB left)
...
The build will go on, and will warn again when the disk space reduces
more than interval.
ii) BB_DISKMON_ACTION = "NO_NEW_TASK"
WARNING: The free space of /dev/sdb4 is running low (119.689GB left)
WARNING: No new tasks can be excuted since BB_DISKMON_ACTION = "NO_NEW_TASK"!
The build will stop after other tasks has been done
iii) WARNING: The free space of /dev/sdb4 is running low (119.689GB left)
ERROR: Immediately abort since BB_DISKMON_ACTION = "ABORT"!
The build will stop immediately.
b) The similar to the inode, and also the similar to more than one disks
are monitored.
