2011-02-28Merge branch 'lukas/tools/cover_mem_footprint/OTP-9043' into devLukas Larsson
* lukas/tools/cover_mem_footprint/OTP-9043: Update testcases which need crypto to be skipped on platforms which does not have crypto Update internal pmap to have a process limit Add write concurrancy to cover masters ?COVER_TABLE Update documentation to reflect performance enhancement changes of cover Add aync_analyse_to_file function to cover Split the cover ets tables into two tables, one with the clause info and one with the bump info. This will make it faster to search the tables when analyzing and exporting data. Add process debug tags Update remote collect to handle multiple requests at once Remove io printout warnings when exporting an imported module Make the call to cover parallel so that the test_server takes advantage of the new cool parallel cover features. Update cover to allow multiple analyse and analyze_to_file calls at the same time. For each call a seperate process will be spawned to handle the request. Refactor cover to prepare it for making analysis parallel Update remote loading to only load a certain number of modules at a time to prevent memory usage explosion Conflicts: lib/tools/test/cover_SUITE.erl

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.

2010-09-30Emacs erlang-mode: fix syntax highlighting of $ in two casesMagnus Henoch
A string whose last character is a dollar sign used to make the syntax highlighter believe that the string never ends, breaking highlighting of following code: -vsn("$Revision: 42 $"). And the double quote as a character constant with a (superfluous) backslash used to make the syntax highlighter believe that a new string started: foo() -> $\". This change fixes both problems by adding two regexps to font-lock-syntactic-keywords in erlang-font-lock-init. One case that is still broken is when a multi-line string ends with a dollar sign: bar() -> "This multi-line string ends with a $". baz() -> this_gets_incorrectly_highlighted.

2010-08-10Rewrite ethread libraryRickard Green
Large parts of the ethread library have been rewritten. The ethread library is an Erlang runtime system internal, portable thread library used by the runtime system itself. Most notable improvement is a reader optimized rwlock implementation which dramatically improve the performance of read-lock/read-unlock operations on multi processor systems by avoiding ping-ponging of the rwlock cache lines. The reader optimized rwlock implementation is used by miscellaneous rwlocks in the runtime system that are known to be read-locked frequently, and can be enabled on ETS tables by passing the `{read_concurrency, true}' option upon table creation. See the documentation of `ets:new/2' for more information. The ethread library can now also use the libatomic_ops library for atomic memory accesses. This makes it possible for the Erlang runtime system to utilize optimized atomic operations on more platforms than before. Use the `--with-libatomic_ops=PATH' configure command line argument when specifying where the libatomic_ops installation is located. The libatomic_ops library can be downloaded from: http://www.hpl.hp.com/research/linux/atomic_ops/ The changed API of the ethread library has also caused modifications in the Erlang runtime system. Preparations for the to come "delayed deallocation" feature has also been done since it depends on the ethread library. Note: When building for x86, the ethread library will now use instructions that first appeared on the pentium 4 processor. If you want the runtime system to be compatible with older processors (back to 486) you need to pass the `--enable-ethread-pre-pentium4-compatibility' configure command line argument when configuring the system.
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).

2010-06-07erlang-eunit: remove runtime dependency on cl packageChris Bernard
Follow the GNU recommendation of not introducing runtime dependencies on the Common Lisp package in ELisp packages that will be distributed for widespread use. In practice this means it's ok to use cl macros but not functions.
2010-06-07Add Emacs EUnit feature: run recentChris Bernard
This determines the most recent invocation of EUnit and runs it again -- whether one test or all tests in a module were run (and if all a module's tests were run, whether cover compilation was involved). This can be especially handy when one test is being run repeatedly, eliminating the need to position the cursor in the desired test just to run it. Default keybinding: C-c C-e l
