* sverker/full_INTEGER_EXT/OTP-8540:
term_to_binary use all 32 bits of INTEGER_EXT
|
|
* sverker/driver_int64_bug/OTP-8716:
Fix bug that caused faulty 64-bit integers from drivers.
|
|
|
|
* se/http_response_empty_phrase:
{packet,http} allow empty response phrase
|
|
Earlier, external format INTEGER_EXT was only produced for 28-bit
signed integers. Now full 32-bit signed integers are produced as
INTEGER_EXT to avoid the more costly SMALL_BIG_EXT format. Both old
and new code can read 32-bit INTEGER_EXT.
Also fixed integer encoding bugs in erl_interface erl_encode/erl_decode.
(Thanks to Alexander Demidenko for reporting)

Packet type 'http' for erlang:deocode:packet and gen_tcp allow a
response line with an empty phrase string, like
"HTTP/1.1 200\r\n".
Earlier, an empty phrase was only accepted if the status code
was followed by space or tab, like
"HTTP/1.1 200 \r\n".

The erlang:open_port spawn and spawn_executable directives can include
an {env, Env} directive to set up environment variables for the
spawned process. Variables can be unset with {"NameOfVariable",false}.
A bug in ert/emulator/sys/unix/sys.c could cause unset variables
to not be unset. This would typically happen if there where more
variables to be unset than there where already set variables in the
destination evironment.
Fix this problem for unix and add a new regression test for it to
the port test suite. Windows does not seem to have the same problem.

* origin/pan/otp_8579_autoimport_override:
Update preloaded modules
Update primary bootstrap
Remove outcommented code from erl_lint
Make port_command/3 auto-imported
Remove (harmless) warnings about min/max in core applications
Autoimport min/2 and max/2
Improve coverage of erl_int in testcases
Change warning to error for nowarn_bif_clash compiler directive

Add some testcases to compiler to verify that overriding really happens
Return nowarn_bif_clash functionality but with warning
Teach erl_lint to better override BIFs with local functions and imports
Teach compiler to override autoimport with import
First prototype for local functions overriding autoimported
OTP-8579 Local functions should override auto-imported
Local and imported functions now override the autoimported
BIFs when the names clash. The pre R14 behaviour was that
autoimported BIFs would override local functions. To avoid
that old programs change behaviour, the following will
generate an error:
Doing a call without explicit module name to a local function
having a name clashing with the name of an autoimported BIF
that was present (and autoimported) before OTP R14A
Explicitly importing a function having a name clashing with
the name of an autoimported BIF that was present (and
autoimported) before OTP R14A Using any form of the old
compiler directive nowarn_bif_clash
If the BIF was added or autoimported in OTP R14A or later,
overriding it with an import or a local function will only
result in a warning,
To resolve clashes, you can either use the explicit module
name erlang to call the BIF, or you can remove the autoimport
of that specific BIF by using the new compiler directive
-compile({no_auto_import,[F/A]})., which makes all calls to
the local or imported function without explicit module name
pass without warnings or errors.
The change makes it possible to add autoimported BIFs without
breaking or silently changing old code in the future. However
some current code ingeniously utilizing the old behaviour or
the nowarn_bif_clash compiler directive, might need changing
to be accepted by the compiler.

* jv/autoimport-binary_to_term_2:
Change binary_to_term/2 to be auto-imported
OTP-8671 jv/autoimport-binary_to_term_2
Now, binary_to_term/2 is auto-imported. This will cause a compile warning
if and only if a module has got a local function with that name.

* se/spawn_drv_win_deadlock:
Fix deadlock in spawn driver on windows
OTP-8641 se/spawn_drv_win_deadlock
Windows: Closing port of program that stalled without reading all data
could deadlock scheduler thread.
|
|
A misbehaving port program that does not read all data written to the port
may deadlock the scheduler thread when it calls port_close. The chosen solution
was to use the new function CancelIoEx if it exist (Vista) otherwise let the
spawn driver wait for a short while (10ms) and then to spawn a thread that will
wait for the port program to exit.

Add new NIF API functions
- enif_make_atom_len
- enif_make_existing_atom_len
- enif_make_string_len
These are basically the same as enif_make_atom,
enif_make_existing_atom and enif_make_string except that the
new functions require a length parameter instead of a
null-terminated C-string.

While binary_to_term/2 was added in R13B04, it wasn't auto-imported. This
conformed to longstanding policy of not changing auto-imports between major
versions. This patch contains changes to auto-import binary_to_term/2 to
coincide with the release of R14.

* bg/opt-receive:
Test that gen_server:call/2,3 are fast even with a huge message queue
erts: Add tests for the receive optimization
Update primary bootstrap
erts: Implement recv_mark/1 and recv_set/1 for real
compiler tests: Cover the error handling code in beam_receive
compiler test: Test optimization of receive statements
Optimize selective receives in the presence of a large message queue
Introduce the new recv_mark/1 and recv_mark/1 instructions
Compile tests that communicate with R12 nodes with the r12 option
Move p_run/2 to test_lib
gen: Inline wait_resp_mon/2 to help the compiler optimize
OTP-8623 bg/opt-receive
reveive statements that can only read out a newly created reference are now
specially optimized so that it will execute in constant time regardless of
the number of messages in the receive queue for the process. That
optimization will benefit calls to gen_server:call(). (See gen:do_call/4
for an example of a receive statement that will be optimized.)
|
|
|
|
R12 nodes cannot load code that use the optimized receive that
we are about to implement.

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.

* bg/fconv:
erts: Fix loading of modules with invalid floating point arithmetic
|
|
The following program is supposed to cause an exception
at run-time:
foo() ->
Sum1 = Sum2 = N = 2,
pSum - (Sum1*(Sum2/N)).
but the loader fails to load because it contains the
following instruction:
fconv {atom,pSum} {fr,2}
Fix the loader so that it can handle fconv instructions
where the first operand is a non-numeric literal.

* se/decode_packet:
Fix erlang:decode_packet(httph_bin,..) to not return faulty header strings
OTP-8548 se/decode_packet
erlang:decode_packet(httph_bin,..) could return corrupt header strings or
even crash the VM. This has been fixed. It only happened on 32-bit VM if
the header name was unknown and between 16 and 20 characters long. Sockets
with simular packet option did not suffer from this bug.
|
|
Unrecognized Http header names was sometimes returned as corrupt
sub-binaries pointing to a stack allocated buffer. This only happened
on 32-bit VM if the header name was between 16 and 20 characters
long. It could in some cases lead to segmentation fault.
The solution was to avoid creating sub-binary if the returned string
was not part of the original binary.

The testcase core dunmped. Also made sure the key could actually store
long integers in driver_async (which is more of a cosmetic change).
|
|
The following test suites now work:
send_term_SUITE
trace_nif_SUITE
binary_SUITE
match_spec_SUITE
node_container_SUITE
beam_literals_SUITE
Also add a testcases for system_info({wordsize,internal|external}).
|
|
Some test suites need to differentiate between 32-bit terms
and 32-bit pointers.
While at it, remove some more warnings in process.c for SMP and debug.
