| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Seen symptom: Failed assert DEBUG_PRINT_FD("executed ready_input", state); ASSERT(!(state->active_events & ERTS_POLL_EV_IN)); with state->type == ERTS_EV_TYPE_NIF that is, the fd already closed and then reused by a NIF.

| | | | | | | | | | | | | | | | | | | | | | | | We add a logger filter that removes the verbose error log messages from the driver_SUITE. The log messages will still be in the html logs, they just wont be printed to stdout.
| * | | [erts] reduce console output for Common TestMaxim Fedorov2022-01-081-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | Some test cases produce 20+ Mb of debug output which does not help to figure out a problem. This change suppresses logs, leaving a chance to remove suppression for local runs.
* | | | erts: Stop marking memory regions as discardable (`madvise(2)`)John Högberg2021-12-312-83/+0
|/ / / | | | | | | | | | | | | | | | | | | | | | This has caused a lot of annoying trouble over the years, and the benefits never materialized: none of the supported OS's would not reclaim any pages until they out of physical memory, and most users already had some kind of overload protection that prevented that from happening in the first place.

| * | Limit timeout value in calls to select()Rickard Green2021-11-031-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We previously did not limit the timeout value when calling select() which could cause select() to fail when passed a huge timeout value causing a runtime system crash. We currently only use select() on Darwin which accepts a timeout value of up to 100 million seconds. However, according to posix, select() implementations are only required to provide 31 days as max timeout value. We therefore limit the timeout value to 31 days.

This patch makes it consistent to always show negative floats. io:format/2 has also been fixed to consider negative zeros. This is important because some operations, such as math:atan2, will return drastically different results if negative zeros are given compared to positive zeros. Negative zeros also are encoded differently in bitstrings.
