Introduce new "Dbgi" chunk
OTP-14369
|
|
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.

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.

This commit introduces the following key changes:
- Support for reading tar archives in formats currently in common use,
such as v7, STAR, USTAR, PAX, and GNU tar's extensions to the
STAR/USTAR format.
- Support for writing PAX archives, only when necessary, using USTAR
when possible for greater portability.
These changes result in lifting of some prior restrictions:
- Support for reading archives produced by modern tar implementations
when other restrictions described below are present.
- Support for filenames which exceed 100 bytes in length, or paths which
exceed 255 bytes (see USTAR format specification for more details on
this restriction).
- Support for filenames of arbitrary length
- Support for unicode metadata (the previous behaviour of erl_tar was
actually violating the spec, by writing unicode-encoded data to fields
which are defined to be 7-bit ASCII, even though this technically
worked when using erl_tar at source and destination, it may not have
worked with other tar utilities, and this implementation now conforms
to the spec).
- Support for uid/gid values which cannot be converted to octal
integers.

When at it, types have been added to record fields.

Several people have requested that the assert macros in EUnit should be
moved out to a separate header file. This patch puts them in
stdlib/include/assert.hrl, which gets included by the eunit.hrl file.
Thus, nothing changes for eunit users, but the asserts can now also be
included separately.

* dgud/stdlib/rand/OTP-12586:
stdlib: Document and add normal distributed random value function
stdlib: Add new random functionality/module

As the erl_anno module is used by the compiler, it must be included
in the set of modules that are used when building the primary
bootstrap.
|
|
Introduce erl_anno, an abstraction of the second element of tokens and
tuples in the abstract format. The convention that negative line
numbers can be used for silencing compiler warnings will no longer
work in OTP 19; instead the annotation 'generated' is to be used.

The old random module contains an old algorithm which have flaws
and the api requires the user to invoke seed and or checking if seed have
been invoked, if a non constant seed is to be used.
The api contains the following features:
- The user can invoke rand:unform/[0|1] directly and get a non constant seeding.
- The api is split in functional and non functional functions,
i.e. usage of _s functions will not affect the process dictionary.
- The api contains several algorithms with different characteristics and
can be extended with new algorithms in the future.
- Contains state of the art random number generators.
- Default algorithm is taylor made for erlang to be fast on 64bits machines.

This module has been marked experimental for more than 15 years,
and has largely been superseded by the pg2 module from the kernel
application. The original pg also has no tests and has not been
updated in the last 15 years other than small maintenance edits
(like adding specs or replacing pid/1 by is_pid/1). It is pretty
unlikely that anyone uses it today and its presence is simply
confusing as people should be using pg2 anyway.

Name conforms to EEP.

The map type is set to term.

With silent rules, the output of make is less verbose and compilation
warnings are easier to spot. Silent rules are disabled by default and
can be disabled or enabled at will by make V=0 and make V=1.

Expect modifications, additions and corrections.
There is a kludge in file_io_server and
erl_scan:continuation_location() that's not so pleasing.

Commit df8e67e203b83f95d1e098fec88ad5d0ad840069 broke
"./otp_build update_primary" because epp:parse_file/4 was
added and used from the compiler, but the epp module is not part
of the primary compiler that is used to compile the bootstrap
compiler. Fix the problem by including the epp module in the
primary compiler.

* bg/otp_build-improvements:
Fix spelling, remove obsolete command
Support updating preloaded files in a git repository
Support updating the primary bootstrap in a git repository
Determine which VCS is being used
stdlib makefile: Add explicit rule
OTP-8369: bg/otp_build-improvements
|

When building a primary bootstrap in a git repository, the file
bootstrap/lib/stdlib/egen/erl_parse.erl would not get updated.
With clearmake, this file is updated.
Adding an explicit rule for the file make it it work with GNU Make.
While at it, remove an out-commented rule.
