* bjorn/xml-encoding-fix/OTP-11310:
Change encoding of troublesome notes.xml files to utf-8
Convert some notes.xml files from latin-1 to utf-8
|
|
Most notes.xml files will be updated in every release and cause
the kind of the problems described in the previous commit.

When reporting a field redefinition in a record, erl_lint can forget
about some old unused variables.
f() -> X = 1, #r{a=foo,a=bar,a=qux}.
|
|
Variables used in the body of a try expression were marked as unsafe
*and* used, which makes no sense as an unsafe variable can't be used.
Function vtsubtract/2 is used to forget usage of such unsafe variables.

When analyzing complex expressions (i.e. comprehensions, cases, tries,
ifs and receives), erl_lint does not forget about old unused variables
when returning the updated variable table. This causes a bug where old
unused variables are not recorded as such:
t(X, Y) ->
#r{a=[ K || K <- Y ],b=[ K || K <- Y ]}.
As erl_lint uses vtmerge_pat/2 to merge the results of the analysis of
the two list comprehensions, X is marked as used and the warning is not
emitted.
The function vtmerge_pat/2 is used instead of the similar vtmerge/2
which does not mark multiple occurrences of a variable as usage to
handle cases like the following one:
t(X, Y) ->
#r{a=A=X,b=A=Y}.
Other simpler expressions like conses, tuples and external fun
references do not correctly follow this behaviour, e.g. A is not marked
as used in the following code:
t(X, Y) ->
{A=X,A=Y}.
This commit fixes both issues and makes erl_lint not return old unused
variables in updated tables and makes all compound expressions use
vtmerge_pat/2.

Hi Fredrik,
> I've gotten some feedback from your review,

> yy"++[$\^u]++"z."}, {getline,"z"}],[]).
Please find an updated version of the patch attached to this e-mail. I
hope that you still accept it via e-mail because the former patch was
sent the same way ;-).
I have extended the documentation to list the new key combinations and
added tests to make sure they work.
Kind regards,

Subject: [PATCH] [EDLIN] support a few more control keys
Add support for the following control keys that many users have become
accustomed to:
- <CTRL>+W : backward kill word
- <CTRL>+U : backward kill line
- <HOME> : goto start of line
- <END> : goto end of line
- <CTRL>+<LEFT> : backward word
- <CTRL>+<RIGHT> : forward word
It seems that the <CTRL>+<LEFT|RIGHT> control key sequences are
different between terminal emulators, therefore a few possible
combinations were added (similar to how libreadline is configured).
Documentation and tests are extended to reflect the new functionality.

* jv/update-io_prompt-type/OTP-11208:
Update io:prompt() type
|
|
Most functions in filelib support binaries as arguments but
that was not reflected in the typespecs.
The types filename_all() and dirname_all() were introduced
to mimic file:name_all().
|
|
Functions that expect an io:prompt() also accept binaries and
iolists as arguments. Therefore its type has been updated to
reflect the same types accepted by other io functions.

`I` should be `If`

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).
