| | | | | | | | | | | | | | | | | | When the relay threads encounter an error, they now send SIGTERM to the rest of the process before the thread exit, so we get a clean shutdown. For EPIPE in particular, error messages are also suppressed.

| * | Fix strftime format bugMasami Hiramatsu2009-04-021-3/+6
| | | | | | | | | | | | | | | This fixes bugs in strftime-subset function. This modifies %C, %l and %j to fit the output of date command.
| * | Fix a bug in file size limitation code.Masami Hiramatsu2009-04-022-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a bug in stapio, which checks written data size and switches new file when it exceeds a limit. The problem is that written-data-size counter ignores the first written-data size when switching files. So, actual file size always exceeds the limit. This changes stapio to initialize written-data-size counter with the size of the data which will be written in new file.

| * | PR9821: staprun supports subset of strftime.Masami Hiramatsu2009-03-204-32/+232
| | | | | | | | | | | | | | | Add strftime subset format support for output file name to systemtap. This format will be evaluated when opening a new output file.
| * | PR6930: stapio: support file switchingMasami Hiramatsu2009-03-205-17/+195
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add file-switching option(-S size[,N]) to stapio. This option has two arguments, 'size' and 'N', and requires -o option. - When the size of output file exceeds specified 'size'MB, staprun switches output file to the next file. For this purpose, all output file has a serial number as a suffix only when user specifies this option. - Using this option in bulk mode, the output file name will be 'FILE_cpuX.SERIAL'. - When the number of files exceeds specified N, staprun removes the oldest file. This argument can be omitted.
| * | PR6930: stapio: run in background as a daemonMasami Hiramatsu2009-03-203-4/+84
| | | | | | | | | | | | | | | | | | | | | Add '-D'(daemon mode) option to staprun/stapio for daemon mode. In this mode, stapio shows just its pid and detachs from console. Since it has no stdio, this mode requires -o option. stapio will exit when it receives SIGTERM or detects some error.
| * | PR6930: staprun: supports error message to syslogMasami Hiramatsu2009-03-203-8/+33
| | | | | | | | | | | | | | | Add an interface (eprintf) to output error messages to syslogd, because staprun has no stderr after detaching from console.

| * | PR9947: move runtime cleanup out of the work queueJosh Stone2009-03-131-0/+8
| |/ | | | | | | | | | | | | | | | | | | | | | | The kernel lockdep checking found a possible deadlock if a forced rmmod tried to destroy _stp_work_queue at the same time that the work queue was unregistering tracepoints. An unlikely scenario, but still possible. Now the work queue will just issue a STP_REQUEST_EXIT down to usermode, and usermode will echo back an STP_EXIT that triggers the actual probe cleanup. This way the unregistrations are happening in exactly the same context as the registrations were.
