2017-07-06Break erts_debug:lock_counters/1 into separate BIFsJohn Högberg
2017-07-06Enable lcnt smoke test on all builds that have lcnt enabledJohn Högberg
2017-05-18Make lock counter info independent of the locks being countedJohn Högberg
This allows us to enable/disable lock counting at will, and greatly improves the performance of erts_debug:lock_counters/1 since we no longer have to worry about the lock counters "dying" while we're enumerating them. OTP-14412

2017-05-17Add persistence to history of the non-legacy shellFred Hebert
This patch adds a mechanism by which shell history gets stored persistently on disk and gets loaded whenever a new shell session begins. The log files are added to the user's cache directory, with multiple files in it, although the location is configurable. All Erlang instances on a given host will share the same log file. There are two hook points in group.erl that are used: when instantiating the buffer, where we fetch from disk, and when adding a line to the buffer (gets stored). This allows all shell instances to use the same base set of lines when loaded, but to keep their history separate after the fact. As lines are added as you go, a new shell session (with ^G -> s -> c) will have access to previous sessions' lines. The implementation makes use of the disk_log library with a rotating log in order to store data, and allow automated repairs. By default, the feature is disabled and must be turned on through OTP environment variable part of the kernel application. The options include: | Option | Accepted values | Default | Description | | ------------------------ | ----------------- |---------- | -------------------- | | shell_history | enabled, disabled | disabled | turn feature on/off | | shell_history_path | any string | user cache| where to put files | | shell_history_file_bytes | 51200..N bytes | 512kb | max data size (>50kb)| | shell_history_drop | ["q().", ...] | [] | blacklisted lines | A version header is added to the disk_log configuration, allowing changes in the storage format to be enacted in the future (i.e. adding segmentation by node name in the same file, or encoding) without conflict. Log rotation is used with multiple log files to ensure proper enforcement of resizing without too much data loss. Because disk_log does not allow to just flush bits of content on rewrite (it truncates any full file), we instead use a wrap log and try to divide the configured size into up to 10 log files so that every time we rotate a log, we lose only 10% of the data. This remains true for corrupted files that cannot fully be repaired. This many-logs-based approach in turn forces the use of a minimal log size for the `shell_history_file_bytes` configuration, since it has to be divided by 10. The shell history is not loaded for the `user` process which, despite running the group.erl module, does not actually require history as it mostly just forwards IO protocol information.
2017-05-17add option 'quiet' to disk_logFred Hebert
This option allows to suppress output of info_msgs to error_logger when recoverable errors are encountered in disk_log by setting the value to 'true'. Defaults to 'false', the backwards compatible behaviour.
2017-05-17Fix type declaration for disk_log.hrlFred Hebert
A specific type was given as an atom rather than an actual type defintion.
2017-05-17proc_lib: Don't call erlang:get_stacktrace/0 twiceBjörn Gustavsson
proc_lib calls erlang:get_stacktrace/0 twice, which is unnecessary, and potentially unsafe since there are calls to many functions in between. Any of the calls could potentially cause and catch an exception, invalidating the stacktrace. Only call erlang:get_stacktrace/0 once, and pass the result to the second place where it is needed.
2017-05-17escript: Pick up stacktrace a soon as possibleBjörn Gustavsson
It happens to work today, but it is potentially unsafe to call io:format/2 before calling erlang:get_stacktrace/0. Make the code safe by calling erlang:get_stacktrace/0 directly after catching the exception.

We generally avoid abbreviations such as "e.g." and "i.e." in the documentation. We write "Erlang", not "erlang" (except when referring to the erlang module).
