When tuple funs were still supported, the idiom for allowing
real funs with a certain arity but not tuple funs was:
is_function(Fun) andalso is_function(Fun, Arity)
The reason that both tests were needed is because:
is_function({M,F}) would return 'false'
is_function({M,F}, Arity) would return 'true'
In 53ec991d19, is_function/2 was updated to only return 'false'
for tuples, so the call to is_function/1 can be removed.

When manipulating Core Erlang trees it may be useful to perform some
operation when a node is visited, before inspecting children nodes. The
definition of cerl_tree:mapfold/3 does not allow that, as it applies the
given function only after all the recursive calls on the children nodes
have been completed.
This patch adds a new argument to mapfold: a function that is applied when
a node is first entered.
As an example of its use, consider the case where one wants to move a
'call' node earlier, by adding 'let' node and replacing the 'call' node
with the defined variable. The name of that variable must be specified
before one traverses the inner tree (especially if such replacements can be
nested).

Trace files are typically large but contain small terms so we can expect
a performance gain from read buffering. dbg:trace_client with a dummy
handler ran more then 3x faster on a sample 200MB trace file.
fprof:profile can also gain a bit.

Some of the error reasons were not explained.
|
|
The specifications for functions that load code in the 'code'
module (e.g. code:load_file/1) have some problems:
* The specs claim that the functions can return {error,on_load}, but
they never do. However, they can return {error,on_load_failure} if
the -on_load function in a module fails.
* The specs claim that the functions can return {error,native_code},
but they never do.
While we are it, also extend the on_load_errors/1 test case to test
that the load functions return {error,on_load_failure} when an
-on_load function fails.

There is no reason to export system_continue/3 and system_terminate/4
from code_server. Servers that use proc_lib and 'sys' to handle system
message do need those functions exported, but code_server contains a
modified copy of the system message handling code from 'sys', and that
code only make local calls to system_continue/3 and
system_terminate/4.
|
|
There is unnecessary knowledge about the -nostick option
in the 'kernel' module. -nostick can be handled entirely
in the 'code' module.
There is no need to have both code:start_link/0 and
code:start_link/1. code:start_link/0 is sufficient.
Also get rid of error handling for things that cannot happen:
The 'init' module has made sure that init:get_argument(root)
can't fail, so there is no need for any error-reporting code.
(See e1dc0aa4.)
We also don't need to test the return value from
code_server:start_link/1, because it will always return {ok,Pid}
(or crash).

Remove the first argument for code_server:call(). It makes no
sense. The only caller is 'code'.
Note that the code_server module is undocumented and that
code_server:call() is an internal helper function.

If the file was larger than the OS send buffer the call

* Comment in dialyzer_analysis_callgraph what the call to
dialyzer_coordinator does;
* Delegate activation request to each dialyzer_worker;
* There is no reason for the dialyzer_coordinator to request
activation on behalf of the workers: let each worker request its
own activation as it leads to more consistent dialyzer_worker
module (activation is request as soon as status running is hit -
reguardless of mode) and it reduces lines of code.
* Clarify types in coordinator and worker e.g. make opaque and make
type more strict.

Also clarify in which modes the states `updating` and `waiting` can
happen in the loop.

is a correct simplification and is not relevant.)
