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.

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.

* 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.

* raimo/rand-dev/OTP-14295:
Implement Xoroshiro116+ and improve statisticals
|
|
Implement Xoroshiro116+ as 'exrop' with fixes.
Deprecate all old algorithms but reincarnate 'exs1024' as 'exs1024s'
and 'exsplus' as 'exsp' with fixes.
Fixes:
* Avoid skew for uniform integers caused by using a simple 'rem'
operation for range confinement. Correctness requires retry
with new random value for an unfortunate first value.
* Implement a correct algorithm that collects enough random
bits for ranges larger than the generator's precision.
* Fix uniform density for floats by acquiring 53 bits
then multiplying with 2.0^(-53) which produces floats
on the form N * 2.0^(-53).

In OTP 20, all Unicode characters are allowed in atoms.
However, we have decided that we will not allow non-latin1
characters in module names in OTP 20. This restriction may
be lifted in a future major release of OTP.
Enforce the restriction in erl_lint, so that it will be a
compilation error to have a module name containing non-latin1
characters. That means that tools such as debugger, xref,
dialyzer, syntax_tools, and so on, do not have to be modified
to handle non-latin1 module names.

The following calls:
- otp_internal:obsolete(rpc, safe_multi_server_call, 2).
- otp_internal:obsolete(rpc, safe_multi_server_call, 3).
threw an unhandled exception.
The return value has been amended to match the relevant pattern of
obsolete/3.

Also let the test suite verify that all files that are
opened will be closed before the end of each test case.
aa0c4b0df7cdc7 introduced the file descriptor leak.
