* logwrapper: Add ability to log to kernel logKen Sumrall2013-04-141-3/+26
| | | | | | | | | Also add ability to do abbreviated logging where only the first 4K bytes and last 4K bytes of output are added to the desginated log. Also update standalog logwrapper command to support the new options. Change-Id: Ia49cbe58479b9f9ed077498d6852e20b21287bad
* logwrap: Change semantics of NULL status in android_fork_execvpRom Lemarchand2013-02-081-1/+4
| | | | | | | | When passing a NULL status to android_fork_execvp the return status will now be the return value of the child if it exited properly, otherwise a non-0 value will be returned. Change-Id: I13309c61b37b6b3f9d5507f7d6484e7b6baaf8d0
* logwrapper: rename logwrap() to android_fork_execvp()Rom Lemarchand2013-01-301-3/+3

* logwrap: wait for child process when receiving SIGINT or SIGQUITRom Lemarchand2013-01-291-1/+7
| | | | | | | | | - Wait for the child to exit before propagating SIGINT and SIGQUIT to the parent - Add ignore_int_quit argument to logwrap() that gives the caller the option to ignore SIGINT and SIGQUIT while logwrap is running Change-Id: If5c96cf23094917211310f00aa6aed515f110f5b
* logwrapper: prevent logwrap from hanging when child diesRom Lemarchand2013-01-141-1/+23
| | | | | | | | Sometimes the read on the PTY can wait indefinitely if the child dies. By using a poll statement that monitors both the output of the child and its state we prevent this from happening. Change-Id: I51d5556c66f039bca673145ca72db262977e1689
* logwrapper: split into liblogwrap and the executable itselfRom Lemarchand2013-01-111-0/+27
