In the future, erlang:get_stacktrace/0 will probably only work
inside a the 'catch' block of a 'try' expression.
Future-proof the code by rewriting the old-style catch to
a try...catch.

* sverker/ets-select-replace-const:
stdlib: Add examples for ets:select_replace docs
erts: Fix ets:select_replace with {const, NewTuple}
|
|
|
|
Enable ets:select_replace to do a generic single object
compare-and-swap operation of any ets-tuple using
a matchspec like this:
[{Old, [], [{const, New}]}]
The only exception when this does not work is if the key
contains maps or atoms looking like variables (like '$1').

The extended parser introduced in last commit is used in qlc for
solving an old bug: pids and refs could not be parsed by
string_to_handle(). The parser is also used for adjustments regarding
ETS identifiers (now references) in qlc_SUITE.
Notice that pids, references, ports, and external functions that
cannot be created in the currently running system cause syntax errors
(as before).
|
|
As of Erlang/OTP 20.0, the type of ETS tables, ets:tid(), is a
reference(). A request was put forward that the Erlang shell should be
able to handle references in its input.
This commit introduces an extended parser in module lib. It can parse
pids, ports, references, and external funs under the condition that
they can be created in the running system. The parser is meant to be
used internally in Erlang/OTP. The alternative, to extend erl_scan and
erl_parse, was deemed inferior as it would require the abstract format
be able to represent pids, ports, references, and funs, which would be
confusing as they are not expressions as such, but data types.

Introduce new "Dbgi" chunk
OTP-14369

* raimo/rand-dev/OTP-14295:
Polish

|
|
* lukas/erts/list_to_port/OTP-14348:
erts: Add erlang:list_to_port/1 debug bif
erts: Auto-import port_to_list for consistency
erts: Polish off erlang:list_to_ref/1
|
|
|
|
Follow the same pattern as pid_to_list
|
|
The new Dbgi chunk returns data in the following format:
{debug_info_v1, Backend, Data}
This allows compilers to store the debug info in different
formats. In order to retrieve a particular format, for
instance, Erlang Abstract Format, one may invoke:
Backend:debug_info(erlang_v1, Module, Data, Opts)
Besides introducing the chunk above, this commit also:
* Changes beam_lib:chunk(Beam, [:abstract_code]) to
read from the new Dbgi chunk while keeping backwards
compatibility with old .beams
* Adds the {debug_info, {Backend, Data}} option to
compile:file/2 and friends that are stored in the
Dbgi chunk. This allows the debug info encryption
mechanism to work across compilers
* Improves dialyzer to work directly on Core Erlang,
allowing languages that do not have the Erlang
Abstract Format to be dialyzer as long as they emit
the new chunk and their backend implementation is
available
Backwards compatibility is kept across the board except
for those calling beam_lib:chunk(Beam, ["Abst"]), as the
old chunk is no longer available. Note however the "Abst"
chunk has always been optional.
Future OTP versions may remove parsing the "Abst" chunk
altogether from beam_lib once Erlang 19 and earlier is no
longer supported.
The current Dialyzer implementation still supports earlier
.beam files and such may also be removed in future versions.

stdlib: Fix documentation on sets’ representation
|
|
The Erlang shell's temporary support for Unicode node names is
removed. There will be no support for Unicode node names in
Erlang/OTP 20.0.
|
|
The Unicode translation modifier 't' is added to the io:fread/2,3
control sequence 'a'.
|
|
As of the introduction of Unicode characters in atoms, the control
sequences 'w' and 'W' can return non-Latin-1 characters, unless some
measure is taken.
This commit makes sure that '~w' and '~W' always return Latin-1
characters, or bytes, which can be output to ports or written to raw
files.
The Unicode translation modifier 't' is needed to return non-Latin-1
characters.

* dgud/stdlib/unicode-string/OTP-10289:
Handle chardata in string:to_float and string:to_list
New unicode aware string module that works with unicode:chardata()
Add nf(k)d, nf(k)c conversion functions to unicode module
Reorder code and whitespace fixes
Add unicode_util
|
|
|
|
Works with unicode:chardata() as input as was decided on OTP board
meeting as response to EEP-35 a long time ago.
Works on graphemes clusters as base, with a few exceptions, does not
handle classic (nor nfd'ified) Hangul nor the extended grapheme
clusters such as the prepend class. That would make handling binaries
as input/output very slow.
List input => list output, binary input => binary output and
mixed input => mixed output for all find/split functions.
So that results can be post-processed without the need to invoke
unicode:characters_to_list|binary for intermediate data.
pad functions return lists of unicode:chardata() for performance.
|
|
|
|
Put internal functions below api functions.
|
|
A base for unicode functions, not intended to be a user api.
Whitespace returns a reasonable subset of non nobreak whitespace
characters.
Implementation notes:
Make function clauses instead of using arrays and store tuples instead
of maps to save space.
