* 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).

* 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 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.

* sc/darwin_build_rm_dSYMN:
Fix 'make clean' in erts with debug builds under Darwin
|
|
The Apple compiler creates DWARF debugging symbols in a bundle (ie. a
directory) named <name>.dSYM
In order for make clean to work correctly, the rm command needs -r

* 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
changed. (See the section about code loading in the Reference
manual.)
|
|
|
|
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.

new mandatory configuration variable that replaces all other
previously mandatory configuration variables, and better
documentation. Note that old cross compilation configurations
cannot be used without modifications.
For more information see the $ERL_TOP/xcomp/README file.

* bg/slimmer-history:
beam_makepos: Do not put any dates in generated files
compiler: Teach 'slim' to omit compilation info
|
|
We don't want to have dates in files that are checked-in as
part of the bootstrap compiler (such as beam_opcodes.{erl,hrl})
as a new version will be created every time.

NIF function prototypes in order to allow more than 3 function
arguments. Also an incompatible change in the return value of
erlang:load_nif/2. Added support for references, floats and term
comparison in NIFs. Read more in the documentation of erl_nif and
erlang:load_nif/2.

The correct value for the second argument to erlang:split_binary/2
(Pos) is 0, not 1.

* mh/to_erl-error-messages:
to_erl: Include strerror(errno) in error messages
OTP-8325 to_erl will now include the system error string in error messages
to make it easier to understand what the real problem is. (Thanks
to Magnus Henoch.)
|
|
The MIB compiler in the snmp applications formats its warnings slightly
differently, so we'll need to update the regexp that should match the
expected output.

|
* ks/dialyzer-wx-fix:
dialyzer: make -wx always start the SMP emulator
|
|
The erlang:make_stub_module/3 BIF (which is only used for
loading native code) does not zero the word that points out
an on_load routine (if any). As that word most proably will
contain a non-zero value, the erlang:module_loaded/1 BIF will
think that the module has an on_load routine which has not
returned and will always return 'false'. That in turns causes
various problems for the native code test cases.

to_erl likes to print the message "No running Erlang on pipe ...",
no matter what the problem actually was. The wording might make
you forget that you just need to run to_erl as another user,
for example.
With this change, to_erl will print the system error message
in addition to its own.
Example output:
No running Erlang on pipe pipes/erlang.pipe.5: Permission denied
(wrong user, wrong permissions, etc)
No running Erlang on pipe pipes/erlang.pipe.5: No such device or address
(this actually means "no running Erlang")
No running Erlang on pipe pipes/erlang.pipe: No such file or directory
(not only is there no running Erlang, there are also no pipes at all)

The wx application will only work in the SMP emulator,
so the -wx option for 'dialyzer' must force the -smp
option when starting the emulator.
Make sure that -wx in *any* position on the command
line (not only as the first argument) forces the
SMP emulator.
