2018-01-05stdlib: Let filelib:find_source() search subdirsHans Bolinder
The Design Principles states that an application can have Erlang source files one level below the "src" directory, and now filelib:find_source() by default searches one level below "src". The same applies to "esrc". That directory is only mentioned in filename(3).
2018-01-03Disallow NULs in filename-encoded stringsJohn Högberg
Previously we accepted trailing NULs, which was backwards compatible as such usage never resulted in misbehavior in the first place. The downside is that it prevented erts_native_filename_need from returning an accurate number of *actual characters*, needlessly complicating encoding-agnostic code like erts_osenv.

The option no longer does anything; systems that lack support for non-blocking sendfile(2) will use the Erlang fallback.
2017-11-30Update file performance adviceJohn Högberg
The parts relating to drivers/ports are now obsolete, and the provided example was far noisier than it had to be; the only relevant metric is the number of calls and it's up to the user to decide how those will be reduced. One could argue for its complete removal, but I'm inclined to leave it be.

This commit also adds a check to see that all files that are part of an xi:include also have part of XML_FILES and vice versa. It also fixes any applications where this was not true.

2017-10-11Don't allow null chars in various stringsRickard Green
Various places that now reject null chars inside strings - Primitive file operations reject it in filenames. - Primitive environment variable operations reject it in names and values. - os:cmd() reject it in its input. Also '=' characters are rejected by primitive environment variable operations in environment variable names. Documentation has been updated to document null characters in these types of data as invalid. Currently these operations accept null chars at the end of strings, but that will change in the future.

query was no longer a keyword since the commit 0dc3a29744bed0b7f483ad72e19773dc0982ea50 2012-11-19. So the quotes around query, when it used as atom, no needed.

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.
