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).

2010-05-19Change make:files to behave more like erlcSam Bobroff
Currently make:files will fail with the atom 'error' and no message when the input (.erl) file is unreadable or the output (.beam) file is unwritable. This differs from erlc which will print a useful error message, or when possible, remove the unwritable output file and continue successfully. This change removes the unnecessary checks on the files when make:files is called and allows the error checking to be done in compile:file, where the error messages are produced. It does not affect the return value. In particular this resolves the mysterious problem of make:files failing but erlc succeeding, caused by an unwritable (usually root owned) beam file in an otherwise writable build directory.

The Lock profiling tool, lcnt, can make use of the internal lock statistics when the runtime system is built with this feature enabled. This provides a mechanism to examine potential lock bottlenecks within the runtime itself. - Add erts_debug:lock_counters({copy_save, bool()}). This option enables or disables statistics saving for destroyed processes and ets-tables. Enabling this might consume a lot of memory. - Add id-numbering for lock classes which is otherwise undefined.
