* ms/file-exclusive-mode:
Update preloaded modules
Support opening files in exclusive mode
OTP-8670 ms/file-exclusive-mode
There is a new option 'exclusive' to file:open/2 that uses the OS O_EXCL
flag where supported to open the file in exclusive mode.

OTP-8564: Update deeprication status.
OTP-8573: Inets mod_alias URL rewrite.

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

In commit 1858cb81391d2bce29b4b7620574ca60128cebf7, erl_expand_records
started to optimize is_record/2 in guards by replacing it with
pattern matching (if possible).
Unfortunately, dialyzer will no longer see the code before the
optimization, so any warnings produced in code such as:
case ExprNotProducingRecord#rec{} of
X when is_record(X, rec, N) -> ...
will refer to the optimized code and not the source code,
which is confusing for the user.
Introduce the no_is_record_optimization option for turning off
the optimization and use it in dialyzer.

* uw/mnesia-overload:
Enable continuous monitoring of mnesia overload status

|
* uw/mnesia-schema-merge:
remove debug printout and accidental variable name reuse
Allow a user_defined function to wrap mnesia_schema:merge_schema()
|

Add an option that atomically tests for the existence of a file and
creates it if the file does not exist, by passing the O_EXCL flag
to open() on Unix and CREATE_NEW flag on Windows. Support for O_EXCL
varies across platforms and filesystems.
{ok, Fd} = file:open("/tmp/foo", [write,exclusive]),
{error, eexist} = file:open("/tmp/foo", [write,exclusive]).

OTP-8561: Performance improvments in megaco_config:conn_info
OTP-8627: Fix flex lib(s) installation
OTP-8634: Pending counter raise condition

This was broken during a refactoring of the code.
|
|
Without the instruction defined in ops the interpreter will not
compile when using NO_JUMPTABLE.
|
|
|
|
Documented call time breakpoints in
- erlang:trace_pattern/3
- erlang:trace_info/2
|
|
If a rehash was done the old hash value was used. This was incorrect.
|
|
|
|
|
|
erlang:system_info(snifs) lists all static native implemented
functions. The function presents the lists with three tuple
values containing MFAs [{Module, Function, Arity}, ...].

Call count previously used a global lock for accessing and writing
its counter in the breakpoint. This is now changed to atomics instead.
The change will let call count tracing and cprof to scale better
when increasing the number of schedulers.
|
|
|
|
To solve the issue of multiple schedulers constantly updating the
head pointer to the bp data wheel, each scheduler now has its own
entrypoint to the wheel. This head pointer can be updated without
a locking being taken. Previously there were no lock ...
|
|
|
|
|
|
call_time trace will use instruction pointers instead of
breakpoint data pointers. More costly lookup but the bdt
structure might be deallocated, we do not want that.
Remove unnecessary pattern lock.
|

|
|
|
|
op_i_time_breakpoint is now used
|
|
Call time breakpoint tracing traces per call trace per process.
- Add hashes to support the extra dimension.
- Teach trace_info/2 to handle the extra information dimension.
|
|
|
|
Initial commit with a new breakpoint instruction and PSD areas
for temporary time storage during tracing.
