This name can be used to augment the thread's logging statement with a human-readable name rather than using the pid/tid tuple used elsewhere. Additionally, the thread name is set using the pthread API so that it is visible in GDB and other tools (e.g. htop). Invocations of pgrep in the test utilities are replaced by 'pgrep -f', which matches against the process name. We are not the first to encounter this problem after renaming the main thread, see https://github.com/mongodb/mongo/commit/726cafd713c7333640f8458ec9808ed4f678e3a7#diff-a9003101d1e4a99ac2d43d9b1b839587R122 pgrep uses the name name in /proc/$PID/status which contains the thread name, not the executable name. In the case of the sessiond, this is now "Main". Signed-off-by: Jérémie Galarneau Change-Id: I73dfe8683b2ea31f7ed0c2ffdfa8332f36e28f9b ---
