Code written by Siri Hansen.
2012-12-19[cover] Remove stopped node also from lost_nodes listSiri Hansen
A nodes that was stopped with cover:stop/1 while marked as lost would not be removed from the list of lost nodes. Therefore, if a nodeup was later received for a node with the same name, it would be reconnected. This has been corrected.
2012-12-19[cover] Don't mark stopped node as lostSiri Hansen
Nodes that were stopped with cover:stop/1 were marked as lost and would be reconnected if a nodeup was later received for a node with the same name. This has been corrected.

2012-10-30[cover] Allow reconnection if node has been disconnected or downSiri Hansen
OTP-10523 Earlier, if the connection to a remote cover node was lost, all cover data was lost and the cover_server on the remote node would die. This would cause problems if there were cover compiled modules that would still be executed since they would attempt to write to the no longer existing ets tables belonging to the cover_server. This commit changes this behavior so that the cover_server on the remote node will survive connection loss and continue collecting cover data. If the connection is re-established then the main node will sync with the remote node again and cover data will not be lost (unless the node was down).
2012-10-30[cover] Don't kill remote nodes when connection to main node is lostSiri Hansen
OTP-10523 Since the will probably be cover compiled modules left in the remote node, we want to keep the cover_server and it's ets tables even if connection to remote node is lost. This way it will not crash (due to ets:insert in non existing table) if functions in cover compiled modules are executed.
2012-10-30[cover] Add support for test_serverSiri Hansen
OTP-10523 * Added cover:flush(Nodes), which will fetch data from remote nodes without stopping cover on those nodes. * Added cover:get_main_node(), which returns the node name of the main node. This is used by test_server to avoid {error,not_main_node} when a slave starts another slave (e.g. in test_server's own tests).

2011-11-07EEP-23: Allow variables in fun M:F/ABjörn Gustavsson
Currently, the external fun syntax "fun M:F/A" only supports literals. That is, "fun lists:reverse/1" is allowed but not "fun M:F/A". In many real-life situations, some or all of M, F, A are not known until run-time, and one is forced to either use the undocumented erlang:make_fun/3 BIF or to use a "tuple fun" (which is deprecated). EEP-23 suggests that the parser (erl_parse) should immediately transform "fun M:F/A" to "erlang:make_fun(M, F, A)". We have not followed that approach in this implementation, because we want the abstract code to mirror the source code as closely as possible, and we also consider erlang:make_fun/3 to be an implementation detail that we might want to remove in the future. Instead, we will change the abstract format for "fun M:F/A" (in a way that is not backwards compatible), and while we are at it, we will move the translation from "fun M:F/A" to "erlang:make_fun(M, F, A)" from sys_pre_expand down to the v3_core pass. We will also update the debugger and xref to use the new format. We did consider making the abstract format backward compatible if no variables were used in the fun, but decided against it. Keeping it backward compatible would mean that there would be different abstract formats for the no-variable and variable case, and tools would have to handle both formats, probably forever.

2011-09-21[cover]fix leftover {'DOWN', ..} msg in callers queueHenrik Nord
After stopping cover with cover:stop() there could still be a {'DOWN',...} leftover message in the calling process's message queue. This unexpected leftover could be eliminated if erlang:demonitor/2 with option flush would be used in certain points

with the bump info. This will make it faster to search the tables when analyzing and exporting data. Also made cover export more parallel in how data is collected from the different nodes and also how data is read from ets. This should make the performance of cover much better on machines with multiple CPUs.

2010-09-23add user specified compiler options on form reloadingTobias Schlager
In order to be able to test non-exported functions from another (test) module it is necessary to compile the specific module (at least during the test phase) with the export_all compiler option. This allows complete separation of testing and productive code. At the moment it is not possible to combine this with a test code coverage using the cover module. The problem is that when cover compiling a module using cover:compile_* the code is reloaded into the emulator omitting/filtering the passed user options. In my example above the export_all option would be removed and the non-exported functions cannot be called any more.

2010-07-28Fix cover's HTML-generation logic to escape ampersands in source codeTom Moertel
When cover generates HTML files and embeds source code within them, it does not escape ampersands in the source code. These bare ampersands get misinterpreted by web browsers as HTML character-entity references; as a result, source code containing ampersands renders improperly. This small patch fixes the problem by causing bare ampersands to be escaped into as "&" character-entity references.

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).
