* bjorn/external-funs/OTP-9643:
sys_expand_pmod: Handle external funs in parameterized modules
|
|
clang does not recognize the -no-cpp-precomp option and generates
a warning. -no-cpp-precomp is an obsolete Apple-specific gcc option,
which last had any effect in gcc 3.1 for Jaguar.
Since we cannot build for Jaguar anyway, the configure test added
in 8412a400e92d5cbcd is not needed.

filename:find_src/1,2 will crash when asked to find the source
corresponding to a BEAM with no compilation options. A BEAM file
can be missing compilation options if it has been stripped using
beam_lib:strip/1 or compiled using the undocumented 'slim' option.
Why this matters: If ERL_COMPILE_OPTIONS is set to +slim before
building Erlang/OTP, there will be a crash in 'igor' during the
building of the public_key application. ('igor' merges several
source code files, and uses filename:find_src/1,2 to find the
source code.)
Change filename:find_src/1,2 to return an empty option list if
there are no options in the BEAM file.

Mod:module_info(source_file) is no longer supported (and have not
been for a long time), so calling it will always fail.
|
|
The 'trace' and 'fast' options are no longer supported.
While at it, correct the comment about option filtering.
|
|
The {cwd,Dir} option is always included if the module has been
compiled by erlc. Since its presence cannot be relied upon and it
wastes memory, get rid of it.
|
|
As far as I know, the purpose of the compiler options included in
Mod:module_info(compile) has never been documented.
An educated guess is that they are there in case you want to
re-compile the module with the same options, and also to aid in
debugging when you need to know how a module was compiled.
In neither case is there any need to include options given in the
source itself in options included in Mod:module_info(compile).
Including those options will only waste memory.
Therefore, only include in the BEAM file the options that were
given to compile:file/2.

* bjorn/remove-regexp-module/OTP-9737:
stdlib: Remove the deprecated regexp module
|
|
|
|
|
|
When a new built-in type is introduced, type definitions with the
same name will still be allowed for "a while".
|
|
When a deprecated function has been removed, the compiler will
issue a warning if it sees a call to it, even for functions that
were removed as far back as the R9 release.
Since the otp_internal module grows when new deprecated functions
are added, let's reduce its size somewhat by removing information
about functions that were removed in the R12 release or earlier.

Starting in ff432e262e65243cbc983fcb002527f8fae8c78b, sys_pre_expand
passes external funs through to the downstream passes. It used to
translate external funs to a call to erlang:make_fun/3. Therefore, we
will now need to handle external funs in sys_expand_pmod.

The code is refactored and improved to make it easier to insert the
1/n-1 splitting countermeasure Rizzo/Duong-Beast that is really done
in one function clause in ssl:record_split_bin/3

This option will suppress the 'missing-sasl' warning which otherwise
is issued when compiling a .rel file which does not include the sasl
application.

* ia/ssl/renegotiation-dos-attack/OTP-9739:
Mitigate Computational DoS attack
|
|
On my Linux computer, building the entire Erlang/OTP system
with hipe disabled took about 8 minutes. With hipe enabled,
but without any native code, the build took about 23 minutes,
i.e. more than 3 times slower. (The computer has 4 cores, and
I used 'make -j6'.)
On my eight-core Mac (running 'make -j10') there was only a slight
slowdown when hipe was enabled.
The culprit is hipe_unified_loader:post_beam_load/1, which will be
called every time a module is loaded (even if the module contains no
native code). If post_beam_load/1 is called in a hipe-enabled
emulator, it will block multi-scheduling, even if no work needs to be
done. Apparently the cost for blocking multi-scheduling can vary
greatly, depending on the operating system and system load.
As a quick and conservative fix, don't call post_beam_load/1 unless
some native code has been previously loaded.

Changes to the mechanism for upgrading the emulator in OTP R15 was
erronously not handled in release_handler:upgrade_app, downgrade_app,
upgrade_script and downgrade_script. This has been corrected,
including test and documentation.
