The current "show threads" command was too limited as it was not possible to dump other threads' detailed states (e.g. their tasks). This patch goes further by using thread signals so that each thread can dump its own state in turn into a shared buffer provided by the caller. Threads are synchronized using a mechanism very similar to the rendez-vous point and using this method, each thread can safely dump any of its contents and the caller can finally report the aggregated ones from the buffer. It is important to keep in mind that the list of signal-safe functions is limited, so we take care of only using chunk_printf() to write to a pre-allocated buffer. This mechanism is enabled by USE_THREAD_DUMP and is enabled by default on Linux 2.6.28+. On other platforms it falls back to the previous solution using the loop and the less precise dump. |
