* extrace: detect errors when -d is used HEAD masterLeah Neukirchen2022-10-251-0/+4
|
* sigchld: only quit when we reaped our own childLeah Neukirchen2022-04-161-5/+10
| | | | | Previously, the signal handler would also quit when it was triggered by backgrounding the child.
* sig_atomic_t should be used with volatileLeah Neukirchen2022-01-271-1/+1

* quit when parent specified in -p exitsLeah Neukirchen2022-01-061-0/+3
|
* fix bug where exec() calls would create duplicate entries in pid_dbLeah Neukirchen2022-01-021-1/+10
| | | | Also print execution times for processes that exec'd when -t is used.
* fix -p flagLeah Neukirchen2022-01-021-9/+11
| | | | | Regression from c0e8a5424d, also fix error reporting of processes we don't care about.
* extrace: skip parent lookup for pid 1Alyssa Ross2021-06-151-0/+3
| | | | | | | | | I was getting a lot of errors that looked like extrace: process vanished before we found its parent: pid 1: redirfd Which are easily avoidable. Message-Id: <20210615120801.121874-1-hi@alyssa.is>
* extrace: sync help message and code comments.Érico Nogueira2021-06-091-2/+2
| | | | Closes: #8 [via git-merge-pr]
* extrace: add option to suppress runtime errors.Érico Nogueira2021-06-091-8/+22
| | | | | | | Errors like "process vanished ..." can fill the screen when attempting to run a certain process under extrace, and redirecting all of stderr to /dev/null will hide that process's output. Therefore, we need an option in extrace to hide them.

|
* extrace: use openat() for speedupChris West (Faux)2018-02-081-17/+28
| | | | | | | This reduces the timeframe where the inherently racy access to /proc is done, and removes some unnecessary snprintf. Closes: #2 [via git-merge-pr]
