The problem is that the change in default encoding to utf8 in 17.0, in
commit 00e42967, changes the behaviour of erl_parse:abstract/1, which is
used by the dictionary compiler to turn terms into abstract code. In
particular, it transforms the orddict representation of a parsed
dictionary to contruct the return value of a dictionary module's dict/0
function. This orddict contains various lists, one of which is a list of
tuples of the form
{Name, Code, [VendorId], [Avp]}
where Name is an ASCII string and VendorId is a non-negative integer.
Using erl_parse:abstract/2 instead allows a string encoding to be
specified but regardless of what encoding is used, the result of
transforming our tuple might not be what we really want, which is for
Name to always be represented as a string form and [VendorId] to always
be represented as a cons form: the [VendorId] will always end up as a
string form if the integers are small enough. The only way around this
is to transform the tuple bit by bit, but modifying the code to do this
is quite a lot of work, for not much gain: it would be nice to produce
more readable output but nothing stops working without it.
This commit restores the pre-17.0 conversion by explicilty specifying
latin1 as the string encoding to erl_parse:abstract/2. The utf8 encoding
broke the compilation of some dictionares since unicode strings aren't
expected when writing the generated code to file.
Note that the latin1 encoding does reasonably well in practice, although
it mangles the Ericsson Vendor Id list [193] into a "LATIN CAPITAL
LETTER A WITH ACUTE". The utf8 encoding does worse, mangling the 3GPP
Vendor Id 10415 into "DESERET CAPITAL LETTER CHEE". An ascii encoding
would do better than latin1 but doesn't yet exist. (Encoding isn't
really what the option is. It's a string predicate: if the predicate is
true then represent as a string form, otherwise a cons form.)

A dictionary path containing a unicode codepoint > 255 caused the
function to fail when iolist_to_binary/1 was applied to the path.
|
|
In the case of {call_mutates_state, true} configuration on the service
in question, any peer selection that failed to select a peer resulted in
a case clause failure in diameter_service:pick_peer/5, when the call to
the service process returned false. This was noticed in the case of a
peer failover in which an alternate peer wasn't available.
The explicit matching is intentional, to match exactly what's expected.

* rickard/runtime-dep/OTP-11773:
Introduce system_information:sanity_check()
Verify runtime_dependencies when running 'otp_build patch_app'
Add test-case verifying runtime dependencies found by xref
Introduce runtime_dependencies in .app files
Bump versions and ensure that all are "normal" versions
|
|
|
|
|
|
|
|
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.
|
|
Ensure all are "normal" versions according to the new version scheme
introduced in OTP 17.0

* hb/dialyzer/unknown_warnings:
Introduce a new warning option, 'no_unknown'
Return warnings for unknown types and functions in Erlang Mode
|
|
* vinoski/ds-enif-send:
enable enif_send to work from a dirty scheduler
|
|
Not (yet) documented.
|
|
The warnings about unknown types and functions are now returned
when calling Dialyzer from Erlang, in particular from an escript.
When calling Dialyzer from the command line the warnings about unknown
types and functions are output last as before; and when using the GUI
the warnings are displayed in a pop-up window, as before.

* hb/spec_related_fixes:
test_server: Fix a Dialyzer warning

Fix some Dialyzer warnings

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

cover_SUITE:reconnect/1: Let the other side initiate the disconnect

shell_SUITE: Give bs_match_bin_SUITE/1 more time
|

The call_time trace is a special kind of tracing that requires
a tracer process just like ordinary call trace, but it never
actually sends anything to the tracer. It merely use the existence
of a trace process (and call trace flags) as an indication that
call_time tracing is active for the process.
If the tracer dies in a non-SMP run-time system, processes with
call_time tracing would not notice that the tracer had
died. Furthermore, if the set_on_spawn flag was active, the dead
tracer could be propagaged to newly spawned processes.
Before accumulating trace information in a non-SMP system, always
validate the tracer process. (In an SMP system, a reference to a
dead tracer will be cleared away each time a process is scheduled.)
While we could put all of the new code beam_bp.c, we have chosen to
make a function call from beam_bp.c to a function in erl_trace.c for
clarity's sake and to ease further maintenance. In the future, we
might want to handle tracing in more similar ways in the SMP and
non-SMP system.

The (is_)constant/1 guard is removed from Erlang long ago and thus
there is no need to handle it in RTL.

Don't fail compilation for modules that contain invalid UTF-8
epp: Make it possible to specify a default encoding
|

The introduction of c_map{} and c_map_pair{} unnecessarily broke the
alphabetical order of Core Erlang records. They were probably placed
at the end of the file so as to use other records as types. There is
really no need for this since 'cerl' contains appropriate definitions
of types that can be used for this purpose.
While at it, a type declaration to the c_binary{} definition was added.
|
|
The introduction of c_map and c_map_pair was not done properly. In
particular, the definition of ctype() and an important Edoc comment
were not up-to-date.
While at it,
- some more types were cleaned up and exported so as to be used
in core_parse.hrl and
- some obviously dead code was removed (the type/1 function does
not return 'nil', which in turn simplified a clause in the code
of meta_1/2).

The default encoding for Erlang modules is now UTF-8, and the
compilation would fail if a module contained byte sequences that
are not valid UTF-8 sequences.
In a large project with say many hundreds of Erlang modules
with names of developers such as "Björn" or "Håkan" encoded in
latin-1, that could mean that many hundreds of files would need
to be modified just to get started testing OTP 17.
As a temporary measure to ease the transition, automatically
fall back to the latin-1 encoding with a warning for any module
that contains invalid byte sequences and for which no encoding
has been specified.
The intention is to remove this workaround in OTP 18 or 19.
|

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.
