%%
%% -------------------------------------------------------------------
%% Description of IO handling during execution of parallel test cases:
%% -------------------------------------------------------------------
%%
%% A conf group can have an associated list of properties. If the
%% parallel property is specified for a group, it means the test cases
%% should be spawned and run in parallel rather than called sequentially
%% (which is always the default mode). Test cases that execute in parallel
%% also write to their respective minor log files in parallel. Printouts
%% to common log files, such as the summary html file and the major log
%% file on text format, still have to be processed sequentially. For this
%% reason, the Mode argument specifies if a parallel group is currently
%% being executed.
%%
%% The low-level mechanism for buffering IO for the common log files
%% is handled by the test_server_io module. Buffering is turned on by
%% test_server_io:start_transaction/0 and off by calling
%% test_server_io:end_transaction/0. The buffered data for the transaction
%% can printed by calling test_server_io:print_buffered/1.
%%
%% This module is responsible for turning on IO buffering and to later
%% test_server_io:print_buffered/1 to print the data. To help with this,
%% two variables in the process dictionary are used:
%% 'test_server_common_io_handler' and 'test_server_queued_io'. The values
%% are set to as follwing:
%%
%% Value Meaning
%% ----- -------
%% undefined No parallel test cases running
%% {tc,Pid} Running test cases in a top-level parallel group
%% {Ref,Pid} Running sequential test case inside a parallel group
%%
%% FIXME: The Pid is no longer used.
%%
%% If a conf group nested under a parallel group in the test
%% specification should be started, the 'test_server_common_io_handler'
%% value gets set also on the main process.
%%
%% During execution of a parallel group (or of a group nested under a
%% parallel group), *any* new test case being started gets registered
%% in a list saved in the dictionary with 'test_server_queued_io' as key.
%% When the top level parallel group is finished (only then can we be
%% sure all parallel test cases have finished and "reported in"), the
%% list of test cases is traversed in order and test_server_io:print_buffered/1
%% can be called for each test case. See handle_test_case_io_and_status/0
%% for details.
%%
%% To be able to handle nested conf groups with different properties,
%% the Mode argument specifies a list of {Ref,Properties} tuples.
%% The head of the Mode list at any given time identifies the group
%% currently being processed. The tail of the list identifies groups
%% on higher level.
%%
%% -------------------------------------------------------------------
%% Notes on parallel execution of test cases
%% -------------------------------------------------------------------
%%
%% A group nested under a parallel group will start executing in
%% parallel with previous (parallel) test cases (no matter what
%% properties the nested group has). Test cases are however never
%% executed in parallel with the start or end conf case of the same
%% group! Because of this, the test_server_ctrl loop waits at
%% the end conf of a group for all parallel cases to finish
%% before the end conf case actually executes. This has the effect
%% that it's only after a nested group has finished that any
%% remaining parallel cases in the previous group get spawned (*).
%% Example (all parallel cases):
%%
%% group1_init |---->
%% group1_case1 | --------->
%% group1_case2 | --------------------------------->
%% group2_init | ---->
%% group2_case1 | ------>
%% group2_case2 | ---------->
%% group2_end | --->
%% group1_case3 (*)| ---->
%% group1_case4 (*)| -->
%% group1_end | --->

%% handle_test_case_io_and_status() -> [Ok,Skipped,Failed}
%%
%% Each parallel test case process prints to its own minor log file during
%% execution. The common log files (major, html etc) must however be
%% written to sequentially. This is handled by calling
%% test_server_io:start_transaction/0 to tell the test_server_io process
%% to buffer all print requests.
%%
%% An io session is always started with a
%% {started,Ref,Pid,Num,Mod,Func} message (and
%% test_server_io:start_transaction/0 will be called) and terminated
%% with {finished,Ref,Pid,Num,Mod,Func,Result,RetVal} (and
%% test_server_io:end_transaction/0 will be called). The result
%% shipped with the finished message from a parallel process is used
%% to update status data of the current test run. An 'EXIT' message
%% from each parallel test case process (after finishing and
%% terminating) is also received and handled here.
%%
%% During execution of a parallel group, any cases (conf or normal)
%% belonging to a nested group will also get its io printouts buffered.
%% This is necessary to get the major and html log files written in
%% correct sequence. This function handles also the print messages
%% generated by nested group cases that have been executed sequentially
%% by the main process (note that these cases do not generate 'EXIT'
%% messages, only 'start' and 'finished' messages).
%%
%% See the header comment for run_test_cases_loop/4 for more
%% info about IO handling.
%%
%% Note: It is important that the type of messages handled here
%% do not get consumed by test_server:run_test_case_msgloop/5

%% Support functions for COVER %%

%%
%% A module is included in the cover analysis if
%% - it belongs to the tested application and is not listed in the
%% {exclude,List} part of the App.cover file
%% - it does not belong to the application, but is listed in the
%% {include,List} part of the App.cover file
%% - it does not belong to the application, but is listed in the
%% cross.cover file (in the test_server application) under 'all'
%% or under the tested application.
%%
%% The modules listed in the cross.cover file are modules that are
%% hevily used by other applications than the one they belong
%% to. After all tests are completed, these modules can be analysed
%% with coverage data from all tests - see cross_cover_analyse/1. The
%% result is stored in a file called cross_cover.html in the
%% run.<timestamp> directory of the application the modules belong
%% to.
%%
%% For example, the lists module is listed in cross.cover to be
%% included in all tests. lists belongs to the stdlib
%% application. cross_cover_analyse/1 will create a file named
%% cross_cover.html under the newest stdlib.logs/run.xxx directory,
%% where the coverage result for the lists module from all tests is
%% presented.
%%
%% The lists module is also presented in the normal coverage log
%% for stdlib, but that only includes the coverage achieved by
%% the stdlib tests themselves.
%%
%% The Cross cover file cross.cover contains elements like this:
%% {App,Modules}.
%% where App can be an application name or the atom all. The
%% application (or all applications) shall cover compile the listed
%% Modules.
