If an on_load function had not yet returned, the code server
would only correctly handle calls to code:ensure_loaded/1. That
is, each process that called code:ensured_loaded/1 for the
module in question would be suspended until the on_load function
had returned.
The code server handled calls to code:load_binary/1, code:load_file/1,
and code:load_abs/1 in the same way as for code:ensure_loaded/1.
That means that if call to one those functions attempted to load
*different* code for the module, that code would not get loaded.
Note that code:finish_loading/1 (code:atomic_load/1) will still return
{error,pending_on_load} if there is a pending on_load function for one
of the modules that are about to be loaded. The reason is that
code:finish_loading/1 is meant to either succeed directly, or fail
quickly if there is any problem.

For historical reasons, the second argument in handle_call/3 is
{Pid,Tag}. The tag is always 'call' and is never used.
|
|
Load the module as old code; swap old and new code if the
-on_load function succeeds. That way, a failed update attempt
for a module that has an -on_load function will preserve the
previous version of the code.
|
|
As a preparation for fixing some issues with -on_load(), we will
integrate insert_new_code() into erts_finish_loading. Also rename
insert_new_code() to stub_insert_new_code() to make it clear that
it will only be used when making a stub module

dialyzer: Fix a bug in the translation of forms to types

A bug is fixed, but there are more problems.
Modify erl_types.erl like this:
-define(EXPAND_LIMIT, 500).
and bogus warnings are output (again).
Callbacks and specs are compared (subtype) in dialyzer_behaviour. If
they are expanded to different depths, then invalid warnings can be
generated.

Refactor get_name/1 to facilitate an optimization in the next commit.
|
|
|

make_path() returns a tuple whose second element is not used by
any of its caller. Eliminate the tuple.
Also avoid calling filename:dirname/1 when we already have the result
stored in a variable, and avoid calling filename:basename/2 on a
complete path when we already have the last part of the pathname
stored in a variable.
|
|
absname/1 is quite expensive, so we should not call if we already
have a normalized absolute path.
|
|
The same filtering of sub directories is done in archive_subdirs/1
and try_archive_subdirs/1. Actually, archive_subdirs/1 does nothing
useful. It can be removed and all_archive_subdirs/1 can be renamed
to archive_subdirs/1.
In try_archive_subdirs/1, we can also replace filename:join/1
with the cheaper filename:append/1, since we know that pathnames
have already been normalized.
|
|
It is faster and easier to use filename:split/1 and filename:join/1
than use four different 'filename' operations. Each call in the
original call first flattens the input list, and then traverse the
entire string to the end. So there are roughly 8 complete traversals.
In comparison, filename:split/1 will traverse the input string
twice (once to flatten, once to split) and filename:join/1 once.
For background on why this optimization is worthwhile, here is the
result of profiling the start-up of the run-time system on my computer
(done before this optimization):
$ $ERL_TOP/bin/erl -profile_boot
.
.
.
filename:join1/4 - 13573 : 13805 us
erlang:finish_loading/1 - 27 : 19963 us
filename:do_flatten/2 - 29337 : 49518 us
erlang:prepare_loading/2 - 49 : 52270 us
Note that filename:do_flatten/2 ends up in second place, almost
as expensive as erlang:prepare_loading/2. Your mileage may vary,
depending on the length of $ERL_TOP and the number of extra
directories added to the path using $ERL_LIBS.
