2011-04-29Fix file descriptor leakShunichi Shinohara
File descriptors to import cover data are left opened. When we export and import cover data many times, leaked descriptors cause an error.

2011-02-02Add aync_analyse_to_file function to coverLukas Larsson
2011-02-01Split the cover ets tables into two tables, one with the clause info and one ↵Lukas Larsson
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.

Error caused by low resolution timers.

Option {sort, calls} now sorts on calls. Option {sort, time } now sorts on time.
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.

* egil/eprof: Fix eprof to handle error cases Dialyzer cleanup for eprof Fix fprof_SUITE to use new eprof API Switch pattern API for eprof profile with mfa Update eprof documentation Update eprof_SUITE with more basic tests Rename sorting choices for eprof Teach eprof to align text output Add dump functionality to eprof Add log functionality to eprof Update eprof tests to reflect new eprof Add start timestamp to eprof profiling Teach eprof to use the new breakpoints OTP-8706 egil/eprof eprof has been reimplemented with support in the Erlang virtual machine and is now both faster (i.e. slows down the code being measured less) and scales much better. 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).

When given the option {builtins,true} Xref now adds calls to operators.
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.

* egil/lcnt: Add test suite for lcnt in tools Add lcnt:rt_opt/1 bindings to erts_debug Add runtime option to enable/disable lcnt stats Add auto width on string output Add lcnt documentation Add lock profiling tool OTP-8424 Add lock profiling tool. 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.
