The gen_fsm, gen_server, and wx_object format_status implementations
fail to handle global names of the form {global, term()} where term()
is something other than an atom, pid, or list. Change these
format_status implementations to treat names that are atoms, pids, or
lists as before, but for all other terms, set the header property of
the function return value to a tuple whose first element is a string
describing the return value and whose second element is the name term.
Add unit tests for gen_server and gen_fsm to verify sys:get_status
calls work successfully for globally registered instances.

the socket will be flushed on linux as an effect of setting the nodelay option.

Commit 329f737c03db51918361e127560a6f700e99028e removed
some unused code, but also introduced the need for
further clean-ups.
Fix a spec so that its return corresponds to reality.
Take out code that will never match from a function.

Create and assign the erlang-mode keymap to erlang-mode-map once
erlang.el is loaded, not the first time it is used. This way of doing
it follows the Emacs Lisp convention described at
http://www.gnu.org/software/emacs/manual/html_node/elisp/Tips-for-Defining.html
and also makes it easier for users to customize the keymap.
Remove the now unneeded functions erlang-keymap-init and
erlang-mode-commands.
Also move the definition of inferior-erlang-use-cmm, so it is
available when defining erlang-mode-map.

In code copied (and modified) from the gen_server module, there
are references to the gen_server:print_event/3 function, which is
not exported.
We could export print_event/3 from the gen_server, but in that
case we must promise to keep the function and keep it compatible
in the future. Since the function is small and wx_object already
contains a lot of code copied from gen_server, let's copy the
code for print_event/3 too.
(Thanks to Kostis Sagonas. This old bug was exposed by a patch
by Kostis that replaced "tuple funs" with real funs.)

* sv/format_status_error_info:
Add support for the format_status callback to gen_event
Extend format_status for gen_server/gen_fsm termination error logging
OTP-8630 sv/format_status_error_info
When a gen_server, gen_fsm process, or gen_event terminates abnormally,
sometimes the text representation of the process state can occupy many
lines of the error log, depending on the definition of the state term. A
mechanism to trim out parts of the state from the log has been added (using
a format_status/2 callback). See the documentation.

Make the function names used by M-x imenu contain the function arity
as well as the name. This makes it possible to jump to all functions
of the same name, as opposed to only the one that is defined first.
For example, in the following module there is now a way to jump
directly to foo/1:
-module(foo).
foo() ->
ok.
bar() ->
error.
foo(A) ->
{ok, A}.

Useful for informing the Operating System about the access pattern
for a file's data, so that it can adapt the caching strategy to
maximize disk IO performance.

file:datasync/1 invokes the POSIX system call "int fdatasync(int fd)".
This system call is similar to "fsync" but, unlike fsync, it does not
update the metadata associated with the file (like the access time for
example). It's used by many DBMSs (MySQL and SQLite of example) to
increase disk IO performance, as it avoids disk seeks and disk write
operations compared to fsync.
More details on it at:
http://linux.die.net/man/2/fdatasync
An example, from the MySQL source:
http://bazaar.launchpad.net/~mysql/mysql-server/mysql-5.1-telco-6.1/annotate/head%3A/mysys/my_sync.c#L61
This new function just calls fsync on systems not implementing fdatasync.

The clause that attempts to match a #k_literal{} where
the value is an atom cannot possibly match, since single
atoms are always encoded as #k_atom{}.
|
|
|
|
The clause does not server any useful purpose, since it does the
same as the default clause at the end.
|
|
|
|
|
|
The is_simple/1 function does not need to handle #c_binary{},
since it will never be called with a #c_binary{} argument.
|
|
The state record #core{} has a "es" field that can be used for
causing a compilation error. Since incorrect programs have been
rejected much earlier by erl_lint, no errors were actually stored
in the "es" fields. Therefore, get rid of the "es" field and
the support for generating a compilation error in the v3_core
module.

put_literal/2 was an experimental instruction added in R11 to
support literals, but before the R12 release support for literals
was implemented for all instruction, making the put_literal/2
instruction redundant. Although the beam_disasm module supports
dissambley of instructions in older releases, there is
no reason to have it support experimental instructions.
