2016-10-13handle send_to_non_existing_process trace event in fprofAndreas Schultz
fprof did not handle this trace event. Sending to a non existing process should not be much different from sending to an existing process, so duplicate that logic.

The bug when introduced in OTP-19.0. Optimize adding multiple modules to an Xref server
2016-06-10tools: Optimize adding multiple modules to an Xref serverHans Bolinder
Extracting data from debug info in BEAM files is parallelized. The speed-up is not outstanding. If memory is not an issue, adding `{spawn_opt, [{min_heap_size, <large number>}]}' to the option list of xref:start/2 can make a (small) difference. Reading of modules from a directory is parallelized. Attempts to parallelize all modules when adding a release have been rejected since the gain showed to be small compared to the increased complexity of the code. Using a process for coordinating the reading has not been attempted.

2016-03-01Generalize bit string comprehensionsBjörn Gustavsson
The expression in a bit string comprehension is limited to a literal bit string expression. That is, the following code is legal: << <<X>> || X <- List >> but not this code: << foo(X) || X <- List >> The limitation is annoying. For one thing, tools that transform the abstract format must be careful not to produce code such as: << begin %% Some instrumentation code. <<X>> end || X <- List >> One reason for the limitation could be that we'll get reduce/reduce conflicts if we try to allow an arbitrary expression in a bit string comprehension: binary_comprehension -> '<<' expr '||' lc_exprs '>>' : {bc,?anno('$1'),'$2','$4'}. Unfortunately, there does not seem to be an easy way to work around that problem. The best we can do is to allow 'expr_max' expressions (as in the binary syntax): binary_comprehension -> '<<' expr_max '||' lc_exprs '>>' : {bc,?anno('$1'),'$2','$4'}. That will work, but functions calls must be enclosed in parentheses: << (foo(X)) || X <- List >>

2016-02-03tools: Fix wrong instrumentation of binary comprehensionsLuis Rascao
When cover instruments binary comprehensions it's generating a {block, ...} abstract code term inside a {bc, ...} term that is causing the evaluation to fail at runtime. Removing the block statement eliminates the error. The template of a bit string comprehension cannot have a counter since it is not allowed to be a block.

This is introduced by ab435488a. If a module includes lines which are less than 1, for example a module which includes `eunit.hrl`, its cover output file misses the coverage lines.

* gomoripeti/tools/cover-no-beam/OTP-12806: cover: handle undefined module when analysing to file
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.

2015-05-25Update runtime_dependencies in application resource filesHans Bolinder
Applications that use the new erl_anno module are depending on STDLIB 2.5. Note that CosNotification, Megaco, SNMP, Xmerl, and Parsetools use the erl_anno module via the Yecc parsers only (the header file in lib/parsetools/include/yeccpre.hrl calls the erl_anno module). HiPE does not call the erl_anno module, but uses an exported type. We have chosen to make HiPE dependent on the erl_anno module.

2015-02-25cover: Optimize file operationsBjörn Gustavsson
Use the 'raw', 'delayed_write', and 'read_head' options to speed up file operations. The analysis at the end of: ts:run(compiler, [batch,cover]). is now roughly twice as fast.
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.

An error was introduced in commit f24d1ad9004b2885cd3b15ac0bf9d1407ca68bc8 which reversed the sorting of all locks. This meant that the least contended locks was printed instead of the most contended. This commit reverses the reverse.
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.
