2010-06-14OTP-8710 Fix emulator crash caused by setting CPU topologyRickard Green
A user defined CPU topology set via a call to <seealso marker="erlang#system_flag_cpu_topology">erlang:system_flag(cpu_topology, CPUTopology)</seealso> was not properly verified, and could in worst case cause an emulator crash. The emulator crash could only occur when a user defined CPU topology already existed and was redefined.

* se/port_SUITE_env: fix open_port with many unset env vars allow open_port with env vars with trailing '=' on Windows OTP-8701 se/port_SUITE_env open_port/2 with the spawn and spawn_executable options can include an {env,Env} option. In some cases unsetting variables would not work on Unix (typically if more variables were unset than were actually present in the environment).

2010-06-10fix open_port with many unset env varsSverker Eriksson
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.
2010-06-10allow open_port with env vars with trailing '=' on WindowsSverker Eriksson
Same problem that Steve Vinoski fixed for Unix. Similar fix done in erts/emulator/sys/win32/sys_env.c for Windows. Copy-paste from his commit-message: 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=".
2010-06-09Add -erl_args flag to run_test programPeter Andersson
With -erl_args it's possible to divide the start options on the command line and this way specify explicitly which options are meant for Common Test, and which are meant for other OTP applications (or ERTS).

2010-06-09Add run_test program for Common TestPeter Andersson
Common Test may now be started with the program run_test instead of the legacy shell script with the same name. Minor updates have also been made to the Webtool application.

2010-06-09Merge branch 'pan/otp_8669_doc_autoimported' into devErlang/OTP
* pan/otp_8669_doc_autoimported: Change documentation for erlang:min/2,max/2 and port_command/3 to OTP-8669 erlang:min, erlang:max and erlang:port_command/3 autoimported The recently added BIFs erlang:min/2, erlang:max/2 and erlang:port_command/3 are now auto-imported (as they were originally intended to be). Due to the recent compiler change (OTP-8579), the only impact on old code defining it's own min/2, max/2 or port_command/3 functions will be a warning, the local functions will still be used. The warning can be removed by using -compile({no_auto_import,[min/2,max/2,port_command/3]}). in the source file.

2010-06-04Support opening files in exclusive modeMichael Santos
Add an option that atomically tests for the existence of a file and creates it if the file does not exist, by passing the O_EXCL flag to open() on Unix and CREATE_NEW flag on Windows. Support for O_EXCL varies across platforms and filesystems. {ok, Fd} = file:open("/tmp/foo", [write,exclusive]), {error, eexist} = file:open("/tmp/foo", [write,exclusive]).
