The following compile options are documented:
no_start_optimize
ucp
never_utf
The following run options are documented:
notempty_atstart
{capture, all_names}
The following new functions are documented:
re:inspect/2
|
|
Add notempty_atstart, no_start_optimize, ucp and
never_utf options from new PCRE version.
Use the new notempty_atstart in global matching.
Add inspect/2 function
Correctly handle dupnames when capturing a name, as
in Perl, get the leftmost matching occurence.
Also added all_names, to get all the names in the pattern
in alphabetical (name) order.
To be able to use this in global matching, an inspect
function that can dig out a namelist was added.

It makes no sense to be able to do `<<...,Rest/binary>> <= ...` in a

The default_types() in erl_lint returned a dictionary
with all default types. However, calculating this dict
was expensive and we actually didn't use the default
values in this dictionary.
This patch replaces the dictionary use for one function
that checks if the type is a default type or not,
and remove the bits that checked explicitly for those
default types when iterating the dictionary.

Using the low-level BEAM instructions, we can loop over each message in
the process queue and removes the first message that matches, without
receiving them all to later send them back to itself.
The function prim_eval:'receive'/2 is equivalent to the
following pseudo-code:
'receive'(F, T) ->
RESET MESSAGE QUEUE POINTER,
LOOP:
case PEEK CURRENT MESSAGE WITH TIMEOUT T of
{ok,Msg} ->
case F(Msg) of
nomatch ->
DECREMENT TIMEOUT T,
ADVANCE MESSAGE QUEUE POINTER,
GOTO LOOP;
Result ->
RESET MESSAGE QUEUE POINTER,
Result
end;
timeout ->
RESET MESSAGE QUEUE POINTER,
timeout
end.
To not break Dialyzer and other tools, we use a stub Erlang module which
abstract code is forcefully inserted into prim_inet.erl afterwards
compilation.

In an email to erlang-questions, Bengt Kleberg wrote:
When I use c:ls/1 it reminds me so much of Unix "ls" that I
expect c:ls("filename") to work. The resulting error surprises
me every time (not the same day).
While teaching c:ls/1 to show non-directory files, update the
error handling to make use of the POSIX error codes from
file:list_dir/1 and file:format_error/1 (which had not been
invented when the c module was first implemented).

Since both the STDLIB and compiler applications turn warnings
into errors, we must stop using the old deprecated crypto functions.
While we are at it, generalize the format of the key tuple returned
by beam_lib:make_crypto_key/2 to facilitate introducing new crypto
methods in the future. Change the format to:
{Type,Key,IV,BlockSize}
where Type, Key, and IV are the first three arguments for either
crypto:block_encrypt4/ or crypto:block_decrypt/4, and BlockSize
is the block size for the crypto algorithm (it is needed to properly
pad the plaintext blocks before encryption).

Fix an inconsistent state in epp

This function is used all over the place in OTP itself and people
sometimes want that functionality, they may as well not reimplement it
themselves.
|
|
When entering a new file, epp doesn't properly set #epp.name2 like it
does on initialisation, generating a malformed file attribute when it
leaves the file.

I've found stdlib's timer to burn CPU without good reason. Here's what
happens.
The problem is that it sleeps in milliseconds but computes time in
microseconds. And there is bug in code to compute milliseconds to
sleep. It computes microseconds difference between now and nearest
timer event and then does _truncating_ division by 1000. So on average
it sleeps 500 microseconds _less than needed_. On wakeup its checks do
I have timer tick that already occurred? No. Ok how much I need to
sleep ? It does that bad computation again and gets 0
milliseconds. So next gen_server timeout happens right away only to
find we're still before closest timer tick and to decide to sleep 0
milliseconds again. And again and again.
This commit changes division to pick ceiling of ratio rather than
floor. So that we always sleep not less then difference between now
and closest event time.
