2015-06-10cover: handle undefined module when analysing to filePéter Gömöri
It is possible that not just the source but even the beam of a module is not available when calling analyse_to_file. For example when coverdata is imported from an old file and since then a module was removed. Before this fix cover:analyse_to_file/3 could possibly never return because of a helper process crashed with error:undef and never reply to the caller. At the same time link the helper process to cover_server so any further error won't let the caller waiting indefinitely.

2015-02-20[cover] Improve performanceSiri Hansen
Add functions for cover compilation and analysis on multiple files. This allows for more parallelisation. All functions for cover compilation can now take a list of modules/files. cover:analyse/analyze and cover:analyse_to_file/analyze_to_file can be called without the Modules arguement in order to analyse all cover compiled and imported modules, or with a list of modules. Also, the number of lookups in ets tables is reduced, which has also improved the performance when analysing and resetting cover data.
2014-11-08Fix cover bug on last expressions with empty clausesJosé Valim
OTP-8188 introduced a fix for handling last expressions in expressions like case, try and friends. However the fix did not account that some of those expressions like receive may have no clauses (only an after clause), leading to a function clause error when cover compiling code with such expressions.

2014-03-06cover_SUITE:reconnect/1: Let the other side initiate the disconnectBjörn Gustavsson
The reconnect/1 test starts another node and takes down the connection to it for a while. However, it has been in observed in our daily builds that sometimes a "spontaneous" re-connection occurs. I think that it because of the call to rpc:cast/3 which internally will set the group leader for the remote process to a process on the test_server node. It seems that sometimes the group_leader/2 call will re-establish the connection. Unfortunately, I have not been able to force this to happen by inserting delays in the rpc module, so it it still just an hypothesis. However, letting the other node do the disconnection does seem to fix the problem and intuitively that should be safer way to do it because the group_leader/2 call and the disconnection will be executed sequentially on the same node instead of concurrently from two different nodes.

2014-02-20With --enable-native-libs, skip eprof_SUITE:basic_option/1Björn Gustavsson
eprof does not work on native-compiled code. Since eprof_SUITE:basic_option/1 does profiling on the lists modules, the test case will fail if --enable-native-libs is used.
2014-02-13cover_SUITE: Run part of the test suite when cover is runningBjörn Gustavsson
We used to skip the entire test suite if the cover server had already been started by common_test, but that means that we will get bad coverage for the cover module. Modify the test suite to to run all tests case that don't explicitly start or stop the cover server to increase the coverage. In addition, add a special coverage_analysis/1 test case that only runs when the cover server is already running.

* jv/cover-patches/OTP-10778: Fix a bug in cover when used with no_auto_import Ensure cover keeps the proper file source cover now relies on the compile info to find file sources
2013-01-25Update copyright yearsBjörn-Egil Dahlberg
2013-01-25Fix a bug in cover when used with no_auto_importJosé Valim
Cover was rewriting guard clauses as non-remote calls. That said, if a guard contains erlang:is_binary(Binary), Cover was incorrectly removing the erlang prefix which lead to errors if is_binary is not auto imported. This commit keeps the abstract format as it is.
2013-01-25Ensure cover keeps the proper file sourceJosé Valim
Whenever a module is compiled via compile:forms/2, the source is set to current directory unless a source option is passed to compile. This commit ensures that cover passes the source information to compile:forms/2 to ensure the source won't be modified after the module is cover compiled.
2013-01-25cover now relies on the compile info to find file sourcesJosé Valim
Prior to this commit, cover relied on a simple heuristic that traverses directory from the beam file to find a source file. The heuristic was maintained with this patch but, if it fails, it fallbacks to the source value in the module compile info. In order to illustrate how it works, one of the tests that could not find its source now passes successfully (showing the source lookup is more robust).

2012-12-19[cover] Fix timing dependent bug in cover_SUITE:reconnectSiri 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] 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).
