The beam_lib:cmp/2 function only compares the executable parts
of the BEAM files, not attributes or abstract code. Since the
types and specs (used by Dialyzer) are contained in the abstract
code, beam_lib:cmp/2 will return 'ok' if the only difference
between two BEAM file are in the types or specs.
If an Erlang/OTP system is installed in a revision control
system, and beam_lib:cmp/2 is used to avoid committing unchanged
but newly compiled BEAM files, BEAM files with no other changes
than in types or specs may not get updated, which can problems
if Dialyzer or the debugger is run.
To avoid that problem, change beam_lib:cmp/2 to compare all
chunks *except* for the "CInf" chunk. The "CInf" chunk contains
the compilation time, compiler options, and compiler version.

allow open_port to set env vars containing a trailing '=' character
OTP-8614 sv/env-with-equal-sign
The erlang:open_port spawn and spawn_executable directives can include an
{env,Env} directive to set up environment variables for the spawned
process. A bug prevented applications from using {env,Env} to set an
environment variable whose value ended with a '=' (equal sign) character;
the trailing equal sign was mistaken as an indication that an environment
variable was to be cleared from the environment of the spawned process.
(Thanks to Steve Vinoski.)

When the undocumented ERL_INET_GETHOST_DEBUG environment variable
is set to 5, very long hostnames can overflow the buffer used to
construct the debug message. Truncate debug messages if they exceed
the size of the buffer.
export ERL_INET_GETHOST_DEBUG=5
inet:gethostbyname(lists:duplicate(5000,"x")).

The erlang:open_port spawn and spawn_executable directives can include
an {env, Env} directive to set up environment variables for the
spawned process. A bug in ert/emulator/sys/unix/sys.c prevented
applications from using {env, Env} to set an environment variable
whose value ended with a '=' (equal sign) character; the code mistook
the trailing equal sign as an indication that an environment variable
was to be cleared from the environment of the spawned process.
For example, passing an {env, Env} of
{env, [{"foo", "bar="}]}
would result in the code in sys.c seeing a string of the form
"foo=bar="
The code would see the final '=' character and assume the directive
wanted to clear a variable named "foo=bar" from the environment of the
spawned process, rather than seeing it as a directive to set the
environment variable "foo" to the value "bar=".
Fix this problem and add a new regression test for it to the port test
suite.

There is no reason to define a function that is never used.
|
|
|
|
|
|
In the erts/emulator/beam sources
#ifdef SOME_OPERATING_SYSTEM
should be avoided. Instead, call a function implemented in
sys/OPERATING_SYSTEM/sys.c.
|
|
Remove code supporting testing on OSE/Delta.
Some cross-testing support only used by OSE/Delta is kept
(see the mention of OSE in test_server_internal.hrl), because
it could presumably be useful in the future if we are to test
some other embedded system.

Alert handling has been improved to better handle unexpected but valid
messages and the implementation is also changed to avoid timing related
issues that could cause different error messages depending on network
latency. Packet handling was sort of broken but would mostly work as
expected when socket was in binary mode. This has now been fixed.

Original patch from YAMASHINA Hio posted to erlang-patches@
on Tue Jun 12 11:27:53 CEST 2007:
http://www.erlang.org/pipermail/erlang-patches/2007-June/000182.html
http://fleur.hio.jp/pub/erlang/record2.patch
Only had to do minor changes to port the patch to the
current R14A development tree.
Also added compiler/record_SUITE:nested_access/2 to test
nested record access with or without parentheses.
With this change the following will work.
-record(nrec0, {name = <<"nested0">>}).
-record(nrec1, {name = <<"nested1">>, nrec0=#nrec0{}}).
-record(nrec2, {name = <<"nested2">>, nrec1=#nrec1{}}).
nested_access() ->
N0 = #nrec0{},
N1 = #nrec1{},
N2 = #nrec2{},
<<"nested0">> = N0#nrec0.name,
<<"nested1">> = N1#nrec1.name,
<<"nested2">> = N2#nrec2.name,
<<"nested0">> = N1#nrec1.nrec0#nrec0.name,
<<"nested0">> = N2#nrec2.nrec1#nrec1.nrec0#nrec0.name,
<<"nested1">> = N2#nrec2.nrec1#nrec1.name,
<<"nested0">> = ((N2#nrec2.nrec1)#nrec1.nrec0)#nrec0.name,
N1a = N2#nrec2.nrec1#nrec1{name = <<"nested1a">>},
<<"nested1a">> = N1a#nrec1.name,
N2a = N2#nrec2.nrec1#nrec1.nrec0#nrec0{name = <<"nested0a">>},
N2b = ((N2#nrec2.nrec1)#nrec1.nrec0)#nrec0{name = <<"nested0a">>},
<<"nested0a">> = N2a#nrec0.name,
N2a = N2b,
ok.

The following code never terminates:
fail() ->
Str = "http:/www.flickr.com/slideShow/index.gne?group_id=&user_id=69845378@N0",
EMail_regex = "[a-z0-9!#$%&'*+/=?^_`{|}~-]+"
++ "(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*"
++ "@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+"
++ "(?:[a-zA-Z]{2}|com|org|net|gov|mil"
++ "|biz|info|mobi|name|aero|jobs|museum)",
io:format("about to run...~n"),
Ret = re:run(Str, EMail_regex),
io:format("Ret is ~p~n", [Ret]).
Fix it by having pcre_exec remember match_call_count between restarts.
