* logcat: logcatd: make logcatd killableMark Salyzyn2017-05-311-0/+1
| | | | | | | | | | Near last resort kill logcatd, set /proc/self/oom_score_adj to -600. Can kill to keep system_server, telephony and bluetooth. Test: manual, start logpersist, runs Bug: 62147352 Change-Id: I3723761bf1d2b79ce6a9557d2e78f91cc5497e96
* logcatd: introduce logcatd executableMark Salyzyn2017-04-041-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | logcatd is the same as logcat, except that the -L flag, if supplied, runs once, then the command re-runs itself without the -L flag with the same argument set. By introducing a logcatd daemon executable we can solve the problem of the longish reads from pstore that sometimes occur when the system is excessively busy, starving this background cgroup daemon as we absorb the delay in a backgrounded init "service", rather than in a forgrounded init "exec". This would not have been efficiently possible without the introduction of liblogcat. There are no doubt many flags that make no sense to run twice with, and without, the -L flag. In the general sense we expect the caller to perform the correct set of operations and not pick these nonsense operations. logcatd is only supplied on engineering and debug builds for logpersist, and is only an automated aid to triage. Test: gTest logcat-unit-tests Test: manual confirm logpersist functions as expected, required reboot Bug: 28788401 Bug: 30041146 Bug: 30612424 Bug: 35326290 Change-Id: I53ba31970749daf37eef42636f039f485932416f

| * logcatd: trampoline persist.logd.logpersistd to logd.logpersistdMark Salyzyn2016-07-081-6/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Best practices so that device can set logd.logpersistd properties. Values can be overriden with trampolines for persist.logd.logpersistd values except as designed for empty content to keep out of the way. This allows us to set logd.logpersistd* for a non-persistent collection that does not survive a reboot, and to use persist.logd.logpersistd* for persistent collection that does survive a reboot. Added logd.logpersistd.enable to gate when logpersist service can be run allowing the properties to be adjusted safely prior to this state as is the case for device property. NB: /init will complain when trying to trampoline an empty property, this is acceptable for functionality, but may be considered annoying from the logging perspective.

Publish aliases in help as --size and --buffer. - Add --clear for start command so it clears before starting - shell script bloating up to deal with option validation and provide ERROR: and WARNING: advice. ToDo: - Deprecate shell script and replace with Eng and Userdebug only Developer Options, before it becomes too powerful or bloated to force us to rewrite an expendable like this into C++.
