* egil/eprof:
Fix eprof to handle error cases
Dialyzer cleanup for eprof
Fix fprof_SUITE to use new eprof API
Switch pattern API for eprof profile with mfa
Update eprof documentation
Update eprof_SUITE with more basic tests
Rename sorting choices for eprof
Teach eprof to align text output
Add dump functionality to eprof
Add log functionality to eprof
Update eprof tests to reflect new eprof
Add start timestamp to eprof profiling
Teach eprof to use the new breakpoints
OTP-8706 egil/eprof
eprof has been reimplemented with support in the Erlang virtual machine and
is now both faster (i.e. slows down the code being measured less) and
scales much better. In measurements we saw speed-ups compared to the old
eprof ranging from 6 times (for sequential code that only uses one
scheduler/core) up to 84 times (for parallel code that uses 8 cores).

* 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).

* peppe/common_test_r14_dev_2:
Misc documentation updates
Add documentation for run_test program
Step vsn for test_server to 3.4
Make {repeat*,N} property in group execute the group N times exactly
Fix so that ct_run converts relative diretories in the code path to absolute
Fix bug in handling framework:end_tc timeouts
Fix bug that prevents the interactive shell mode to start properly
Fix failing multiply timetrap test case
Minor fixes in code and test suites
Add support for executing pre-loaded suites (e.g. modules loaded as binaries)
Add test suite for remote loading of binary suites
Fix error with {repeat,0} property in groups causing double iterations
Add support for config info functions (e.g. init_per_suite/0)
Add support for dynamic timetrap handling
Have end_per_testcase run even after timetrap_timeout and abort_testcase
Flush old DOWN messages in demonitor
Add groups in test specifications
Add new tests for test case groups and test specifications
Improve and fix various test suites
Add event_handler_init start flag that can pass init arguments to event handlers

Ssl has now switched default implementation and removed deprecated
certificate handling. All certificate handling is done by the public_key
application.

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.

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=".

To be consistent with the behaviour of the run_test repeat flag/option, the repeat* group property has been changed to specify absolute number of test runs. Previously {repeat,N} meant "execute the group 1 time + N repeats". Now it means "execute the group N times".
|
|
Directories added with run_test -pa or -pz in the pre erl_args part of the command line will be converted from relative to absolute, this to avoid confusion when Common Test switches working directory during the test run.
Also fixed in this commit: Problem with timeouts during init_tc or end_tc (in the Test Server framework).

Also fixed bug in test_server that calls end_per_testcase after test case timeout or abortion.
|
|
|
|
|
|
Also fixed bug: return value {fail,Reason} from end_tc(init_per_suite) was ignored.

Ongoing work...

Also changed: The userconfig option in ct:run_test/1 from 3-tuple to 2-tuple.
|
|
ct_run:script_start() interface
The possibility to pass start arguments to ct_run:start_script/0 by means of an application environment variable has been implemented. This will be used by ct_test_support for automatic testing of all common_test start interfaces.
|
|
Documentation still missing.
|
|
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).
|
|
|
|
General documentation and code updates.
|
|
Documentation changed to specify Firefox as default browser on unix/linux.
|
|
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.
|
|
|
|
node_start+eval -> init(node_start, eval)
Also include some documentation updates.
