2017-05-18kernel: Introcude error_logger:get_format_depth()Hans Bolinder
2017-05-18kernel: Add error_logger:limit_term/1Hans Bolinder
Calling error_logger:limit_term/1 before sending terms as events to the error_logger can be used for limiting the size of the messages. Doing so will not change the output, but potentially save memory. The Kernel variable error_logger_format_depth is used when limiting the size of terms.
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.

2017-05-04inet.xml: fix invalid IPv4-mapped-address examplesKenji Rikitake
* IPv6 address FFFF::192.168.42.2 is an invalid form as an IPv4-mapped address. This should be fixed as ::FFFF:192.168.42.2. The assigned address block is ::ffff:0:0/96. See RFC6890 Table 20 in the Section 2.2.2 for the further details. And for this IPv4-mapped address use *only*, the 32bit LSB of the IPv6 address can be written with the respective IPv4 address. See RFC4291 Section 2.2 Form 3 for the further details.

This commit attempts to clarify some of the guarantees given by the TCP standard when issuing close. This is quite a complex topic so there are probably corner cases still left, but this at least tells the user that things can go wrong when doing a close.

2017-02-21kernel: Fix hanging os:cmd race conditionLukas Larsson
If the port terminates before Port ! close is issued, there will be no 'closed' reply, so the old code would hang. As it turns out there is no way to figure out if a closed reply is supposed to come as that reply is sent after all links and monitors are triggered. So we have to use the synchronous port_close to close the port.

Running this test when for some reason stdlib has been unstickied could cause the emulator to die. So we check first to make sure that the expected files are sticky.
