Error caused by low resolution timers.
|
|
Option {sort, calls} now sorts on calls.
Option {sort, time } now sorts on time.

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.

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.

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.

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).

The eprof documentation is updated to reflect the new eprof application
and some API changes and convenience functions.

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.

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

If the variable 'erlang-eunit-autosave' is non-nil, buffers will be
automatically saved just before running tests -- the "Do you want
to save?" prompt will be inhibited. This can be useful, reducing the
save-compile-load-test cycle to just one keychord.
|
|
Add a number of features to the emacs mode which make it easier to
work with eunit test cases while keeping track of code coverage.
* C-cC-ec:
Compile the module under test for code coverage analysis, run tests
and show the results of the coverage analysis in a new buffer.
* C-c-C-ev:
Compile the current module for code coverage analysis.
* C-cC-ea:
Show the results of the coverage analysis in a new buffer.

Previously there were only two options: either the EUnit test file was
placed directly within the test directory or within the same directory
as the source file. Now a list of candidate locations are supported.
This way more than two alternative locations are supported as well as
arbitrarily deep directory structures (i.e. test/eunit/x_tests.erl).
The default behaviour is still the same, but it's possible to specify
locations by setting the following two variables:
erlang-eunit-src-candidate-dirs
erlang-eunit-test-candidate-dirs

* dgud/emacs-catch-improvements:
Improved indentation of old catch.
Added more type highlighting and fixed record indentation with types.
|
|
An example that didn't work previously.
case Foo of
{ok, X} ->
ok;
_ ->
catch file:close(FD)
end.
|
|
Type highlighting reported by Jay Nelson
non_neg_integer() will highlight purple but pos_integer() does not.
Closing record indentation problem reported by Maxim Treskin:
-record(state, {
sequence_number = 1 :: integer()
}).

Hopefully this covers at least some of the common cases and makes the
flymake support more usable as is. The purpose of including the ebin
directory is to support things like behaviours and parse transforms.

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