2013-03-26[cover] Ensure no process leak when stopping cover on dead nodeSiri Hansen
When cover:stop(Node) was called on a non-existing node, a process waiting for cover data from the node would hang forever. This has been corrected.

* 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

2013-01-25Fix 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).

2012-12-21[cover] Cleanup by stopping cover between testsSiri Hansen
If one test failed, the next would sometimes also fail since cover was not stopped.
2012-12-19[cover] Fix timing dependent bug in cover_SUITE:reconnectSiri Hansen
Adding a timer:sleep between these two lines: net_kernel:disconnect(N1), [] = cover:which_nodes(), This is to make sure the disconnect is detected by cover before checking that the node is gone.
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).

2011-11-07beam_asm: Strenghten the calculation of Uniq for funsBjörn Gustavsson
Funs are identified by a triple, <Module,Uniq,Index>, where Module is the module name, Uniq is a 27 bit hash value of some intermediate representation of the code for the fun, and index is a small integer. When a fun is loaded, the triple for the fun will be compared to previously loaded funs. If all elements in the triple in the newly loaded fun are the same, the newly loaded fun will replace the previous fun. The idea is that if Uniq are the same, the code for the fun is also the same. The problem is that Uniq is only based on the intermediate representation of the fun itself. If the fun calls local functions in the same module, Uniq may remain the same even if the behavior of the fun has been changed. See http://erlang.org/pipermail/erlang-bugs/2007-June/000368.htlm for an example. As a long-term plan to fix this problem, the NewIndex and NewUniq fields was added to each fun in the R8 release (where NewUniq is the MD5 of the BEAM code for the module). Unfortunately, it turns out that the compiler does not assign unique value to NewIndex (if it isn't tested, it doesn't work), so we cannot use the <Module,NewUniq,NewIndex> triple as identification. It would be possible to use <Module,NewUniq,Index>, but that seems ugly. Therefore, fix the problem by making Uniq more unique by taking 27 bits from the MD5 for the BEAM code. That only requires a change to the compiler. Also update a test case for cover, which now fails because of the stronger Uniq calculation. (The comment in test case about why the Pid2 process survived is not correct.)
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.
