We want to add the ability for otp_build to determine which
version control system (VCS) is being used, so that the
commands for updating the primary bootstrap and pre-loaded
modules can be updated to do different things depending on
the VCS.
In the beginning of the otp_build script, set the variable
"version_controller" to either "none" (for no VCS), "git",
or "clearcase".
|
|
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.

* kj/epmd-port2resp-trunc-extra:
Handle "extra" field according to specs in ALIVE2_REQ and PORT2_RESP.
OTP-8361 EPMD now correctly handles the extra data field which can be
given in the ALIVE2_REQ request and retrieved in the PORT2_RESP
response. (Thanks to Klas Johansson.)

Don't let the length field pollute the value of the "extra" field in
ALIVE2_REQ. Extra was read, starting at the second byte of the two
byte length field, which meant that it was included in the result and
the last byte of the value was skipped:
if "extra" is <<1, 2>>, return <<0, 2, 1, 2>> not <<0, 2, 2, 1>>
Increment the offset correctly when sending PORT2_RESP, in order to
make sure the "extra" field won't be truncated:
if "extra" is <<>>, return <<0, 0>> not <<0>>
if "extra" is <<1, 2>>, return <<0, 2, 1, 2>> not <<0, 2, 1>>
Allow null characters in "extra".

Place HighestVersion before LowestVersion, since that is what the
source code does (erl_epmd.erl and epmd_srv.c).

This is an optimization to avoid sending huge terms to the gui
just to step by them and update variables again.
Even better would be to only update if necessary.

* at/windows_build_fixes:
Updated README.win32 for compiling with VS2008 and issues with mc.exe
Allow mc.sh and rc.sh to work when path to mc/rc.exe has spaces
OTP-8345 Building on Windows will now work if the paths to mc.exe and
rc.exe contain spaces. The README.win32 file has been updated
with some information about building using Visual Studio 2008.
(Thanks to Andrew Thompson.)

It must be unsigned so that prim_inet will not reject
when it is sent down again.
(Suggested fix by Raimo for a bug reported by Simon Cornish.)
|
|
The symbol ei_tracelevel was not declared extern which could
crash the linking step on some compilers.
Updated .gitignore to ignore object files in erl_interface.

Suggested by Vlad Dumitrescu.

Visual Studio 2008 puts some things in different places and doesn't
include the Message Compiler (mc.exe).
|
|
The eval call in these scripts was failing for me because the path to
them on my windows machine contained spaces. I also fixed some
copy/paste-os from when (evidently) the mc.sh script was created by
copying the rc.sh script and modifying it.

Automatically indent the line you stand on (end,) before

That way 'end' will be indented correctly after the comma is written.

Fix 'make clean' in erts with debug builds under Darwin

(.eix) of erlang terms that can be read by the erldoc

erlang.org. Added generation of eix files to
otp_release_targets.mk. Fixed a copyright date error in

* bg/on_load:
Test on_load functions that don't return 'ok'
Change the expected return value for on_load functions
OTP-8339 The expected return value for an on_load function has been

manual.)

beam_bool: Fix generation of code that does not validate
Fix crash in beam_bool
OTP-8338 Using complex boolean expressions in ifs could cause the compiler

* as/c_nc-fix:
c_SUITE: Use new style guard tests
Fix c:nc to use outdir or cwd to find compiled object file
OTP-8337 c:nc/{1,2} used to assume that the beam file was created in the
same directory as the source code and failed to load the code if
it was not. Corrected to look for the beam file in the current
directory or in the directory specified by the {outdir,Dir}
option. (Thanks to Alex Suraci.)
|
|
|
|
Before this patch, c:nc would naively assume the object file was created
in the same location as the .erl file. This is often false, for example
when an outdir is specified (often the case in make:all([netload])) or
calling with c:nc("foo/bar") (because compile:file places bar.beam in
the cwd, not foo/).
[ Squashed in minor style changes. /bg ]

An on_load function is supposed to return 'true' to indicate
that the module should be loaded, and 'false' if it should be
unloaded. But returning any other term, as well as causing an
exception, will also unload the module.
Since we don't like boolean values mixed with other values,
change the expected return value as follows:
* If 'ok' is returned, the module will remain loaded and become
callable.
* If any other value is returned (or an exception is generated),
the module will be unloaded. Also, if the returned value is
not an atom, send a warning message to the error_logger
(using error_logger:warning_msg/2).
The new interpretation of the return value means that an on_load
function can now directly return the return value from
erlang:load_nif/2.

The following code (by Simon Cornish)
bad(XDo1, XDo2, Do3) ->
Do1 = (XDo1 =/= []),
Do2 = (XDo2 =/= []),
CH1 = if Do1 == true;
Do1 == false,Do2==false,Do3 == blah ->
ch1;
true ->
no
end,
CH2 = if Do1 == true;
Do1 == false,Do2==false,Do3 == xx ->
ch2;
true ->
no
end,
{CH1,CH2}.
is optimized by beam_bool even though the optimization is not
safe. The trouble is that an assignment to {y,0} no longer
occurs on all paths leading to its use.
The bug is in dst_regs/2 which is supposed to return a set
of all registers assigned in a code block, but it ignores
registers assigned in 'move' instructions.
Fix the bug by taking 'move' instructions into account. This change
is safe since it can only cause more registers to be added
to the MustBeKilled and MustBeUnused sets in ensure_opt_safe/6,
which means that it can only cause the optimization to be turned
off for code that used to be optimized.
