emitted an error. This bug has been fixed.

To be removed in Erlang/OTP 18

When compiling code using deprecated crypto functions that should be
replaced with crypto:hash_update/2, the deprecation warnings were saying
"use crypto:hash_update/3", with the wrong arity of 3, instead of "use
crypto:hash_update/2".
The problem was reported in this email message to erlang-bugs:

Document an escript:create/2 hidden feature

escript:create/2 accepts a 3-elements tuple containing files and
zip:create/3 options to build a zip file.
Also had to update zip typespecs to allow referral from escript docs.

This change relies on the assumption that all arguments before the last --
to the parent beam should be left as they are.

* vinoski/sys-get-rep-state2:
remove tuple funs from special process documentation
fix sys:get_state/1,2 and sys:replace_state/2,3 when sys suspended
OTP-11817
|
|
The 'encoding' option of erl_parse:abstract/2 has been extended to
include 'none' and a callback function (a predicate).
The rationale is that a more general means of determining what integer
lists are to be represented as strings may help readability when
generating Erlang code given input in some other encoding than Latin-1
or UTF-8.
|
|
The grace period is over.
|
|
Since they have not been removed yet in OTP 17, postpone removal
one release to OTP 18.

Add two new system callbacks Module:system_get_state/1 and
Module:system_replace_state/2 to allow sys:get_state/1,2 and
sys:replace_state/2,3 to operate correctly even if a process is sys
suspended. Modify gen_server, gen_fsm, and gen_event to support the new
callbacks.
If a callback module does not export these functions, then by default the
Misc value (the same as that passed as the final argument to
sys:handle_system_msg/6, and returned as part of the return value of
sys:get_status/1,2) is treated as the callback module's state.
The previous behaviour of intercepting the system message and passing a
tuple of size 2 as the last argument to sys:handle_system_msg/6 is no
longer supported.
Add tests to verify the correctness of sys:get_state/1,2 and
sys:replace_state/2,3 when processes are sys suspended. Add two tests for
modules that implement special processes, one that exports
system_get_state/1 and system_replace_state/2 and one that doesn't.
Much of the credit for this patch goes to James Fish, who reported the
initial problem and implemented much of the fix.

Most dependencies introduced are exactly the dependencies to other
applications found by xref. That is, there might be real dependencies
missing. There might also be pure debug dependencies listed that
probably should be removed. Each application has to be manually
inspected in order to ensure that all real dependencies are listed.
All dependencies introduced are to application versions used in
OTP 17.0. This since the previously used version scheme wasn't
designed for this, and in order to minimize the work of introducing
the dependencies.

Dialyzer recognizes a certain pattern that makes it possible to get
rid of 'The created fun has no local return' warnings.

* bjorn/compiler/utf8-warning/OTP-11791:
Don't fail compilation for modules that contain invalid UTF-8
epp: Make it possible to specify a default encoding
|
|
In the next commit, we will need a way to tell epp which the
default encoding should be for files that have no encoding comment.
We could add new open() and parse_file() functions with one
extra argument for the encoding, but there are already too many
variants.
To avoid having to add an additional argument to epp:open() and
epp:parse_file() each time new options are needed, introduce
epp:open/1 and epp:parse_file/2 that takes a property list with
options. Also support the new 'default_encoding' option for specifying
the default encoding for source files.
Thanks to Richard Carlsson for the idea and the implementation
of the new functionality in epp.erl.

erl_lint has since R13B emitted warnings whenever any of the types
arity(), bitstring(), iodata(), or boolean() were re-defined. Now
errors are emitted instead.
|
|
Since Erlang/OTP R16B the linter has not emitted warnings when
built-in types were re-defined. This bug has been fixed.
Thanks to Roberto Aloi for reporting the bug.

Instead of deleting the small file when opening it with
dets:open_file/2 an error message is returned, mimicking the behaviour
when the file is bigger.
open_file/1 has been modified to return the same error message when
the file is small as when the file is bigger.

The deprecation of the built-in types dict/0 and so on had as
side-effect that it was impossible to switch to dict:dict/2 and so on
without getting warnings either in the the previous release (R16B) or
the current one (17.0).
By including the attribute
-compile(nowarn_deprecated_type).
in an Erlang source file warnings about deprecated types can be
avoided in 17.0.
The option can also be given as a compiler flag:
erlc +nowarn_deprecated_type file.erl

Map fields are put in their own function instead of being clauses of expr/3.
Also, invalid map construction expressions now emit one error per ':=' field,
at the location of said field instead of one for the whole expression,
furthermore, such warnings do not stop linting of their key and value
expressions anymore. Ill-formed maps constructions are now also properly
detected in guard expressions.
