stdlib: Add RFC 3339 functions to module calendar

Allow installing multiple instances of sys debug function
This commit solves a bug which allowed installing {Fun,State} as sys debug function even if Fun was already installed. This happened in the case when the current State of the debug fun was undefined.
Also, the new format {Id,Fun,State} of debug functions can be installed, allowing multiple instances of the same fun.

[stdlib/sys.erl] Fix sys module's debug statistics not including the out message count when using gen_server:call/2.
OTP-15047
|
|
Functions for converting between RFC 3339 strings and system time
are added.
Options are lists, but we are considering using maps instead. If we
change, it will happen after Erlang/OTP 21.0-rc1 is released.

stdlib: Add system time functions to module calendar

|
Use the same depth for all (printed) elements of a map.
Since the order of keys can vary when printing a map--maps:iterator/1
and maps:next/1 are used--it is more consistent to print all
associations with the same depth.
If the associations printed are limited by the depth, the selection
of associations is arbitrary, as before.
|
|
Inspiration from module lager_format.
Also some improvements of Unicode handling.
io_lib:format/3 and io_lib:fwrite/3 are new functions. The
representation of the options is a list, but we are considering using
a map instead. If we change, it will happen after Erlang/OTP 21.0-rc1
is released.
|
|
A bug fix: limited maps end with "...", not "...=>...".
A modification: wW separate pairs with " => ", not "=>".
When the output is limited on number of characters, the term is
balanced by wW the same way as is done with pP (see commit bc38638).
|
|
|
|
The name of the io_lib_pretty:print/2 option 'max_chars' is changed to
'line_max_chars' (used by module shell only).
The new option for limiting the number of returned characters of
io_lib_pretty:print() is called 'chars_limit'.

Rationale
Today all compound data types except for maps can be deconstructed in guards.
For tuples we have `element/2` and for lists `hd/1` and `tl/1`. Maps are
completely opaque to guards. This means matching on maps can't be
abstracted into macros, which is often done with repetitive guards. It
also means that maps have to be always selected whole from ETS tables,
even when only one field would be enough, which creates a potential
efficiency issue.
This PR introduces an `erlang:map_get/2` guard-safe function that allows
extracting a map field in guard. An alternative to this function would be
to introduce the syntax for extracting a value from a map that was planned
in the original EEP: `Map#{Key}`.
Even outside of guards, since this function is a guard-BIF it is more
efficient than using `maps:get/2` (since it does not need to set up the
stack), and more convenient from pattern matching on the map (compare:
`#{key := Value} = Map, Value` to `map_get(key, Map)`).
Performance considerations
A common concern against adding this function is the notion that "guards
have to be fast" and ideally execute in constant time. While there are
some counterexamples (`length/1`), what is more important is the fact
that adding those functions does not change in any way the time
complexity of pattern matching - it's already possible to match on map
fields today directly in patterns - adding this ability to guards will
niether slow down or speed up the execution, it will only make certain
programs more convenient to write.
This first version is very naive and does not perform any optimizations.

Currently, in sys:stat/2, the message out only count for system events with format
{out, Msg, To}. However, the gen_server:reply/5 will call sys:handle_debug/4
with format {out, Reply, To, State}. That will make the message out count fail
to pattern matching.
Also update sys_SUITE.erl and relevant docs.

Deprecate erlang:get_stacktrace/1

Compile external fun expressions to literals
OTP-15003
|
|
Change-Id: I5328d5feeac3b7279a8770e8fc27e2d9e8eed359
|
|
* dgud/revert-string-depr:
Revert "Deprecate old string functions"
|
|
The expressions fun M:F/A, when all elements are literals are also
treated as a literal. Since they have consistent representation and
don't depend on the code currently loaded in the VM, this is safe.
This can provide significant performance improvements in code using such
functions extensively - a full function call to erlang:make_fun/3 is
replaced by a single move instruction and no register shuffling or
saving registers to stack is necessary. Additionally, compound data
types that contain such external functions as elements can be treated as
literals too.
The commit also changes the representation of external funs to be a
valid Erlang syntax and adds support for literal external funs to core
Erlang.

* raimo/type-posix-0-overhaul/ERL_550/OTP-14019:
Update types for posix error codes
|
|
I have read the man pages for most socket and file operations
on recent Linux, FreeBSD, OpenBSD and Solaris 10 and noted
the possible error codes.
Which error codes that are possible for file operations have
been updated in file:posix/0. Error codes for socket operations
in inet:posix/0. The latter refers to the former so it is
a superset, assuming that e.g sendfile and AF_UNIX socket
operations could cause socket operations to return any file
error code. That is not entirely true, but could be,
especially in the future.
Added to file:posix/0 are:
ebadmsg edeadlk edeadlock eftype emultihop enobufs enolck enolink
enosr enostr enosys eopnotsupp eoverflow erange etxtbsy
Added to inet:posix/0 are all but:
exbadport exbadseq file:posix()
These are still possible according to erl_posix_str.c,
but are not in file:posix/0 nor in inet:posix/0,
and many of them are not file nor inet related, but some might be:
e2big eadv ealign ebade ebadfd ebadr ebadrpc ebadrqc
ebadslt ebfont echild echrng ecomm edirty

[ERL-557] add is_empty/1 to sets and ordsets

It has been decided that it was to early to deprecate the old
string functions.
This partially reverts commit ccb3f7f9768d3c28783c771df47eec1829e51802.
