In the following code:
m(<<Sz:8,_:Sz/binary>>) ->
Sz = wrong.
the Sz variable is supposed to be bound in the function header and the
matching "Sz = wrong" should cause a badarg exception. But what
happens is that the Sz variables seems to be unbound and the matching
succeds and the m/1 function returns 'wrong'.
If the Sz variable is used directly (not matched), it will have
the expected value. Thus the following code:
m(<<Sz:8,_:Sz/binary>>) ->
Sz.
will correctly return the value of Sz that was matched out from
the binary.

The default value 'undefined' was added to records field types in such
a way that the result was not always a well-formed type. This bug has
been fixed.
---
erl_pp has since OTP-8150 formatted types so that 'undefined' was
removed from union types assigned to record fields. Since one cannot
distinguish between 'undefined' added by the parser or supplied by the
user, a side effect was that user supplied 'undefined's were also
removed.
Now the pretty printer shows 'undefined' even if added by the parser.
This is a minor issue.

This new feature adds the missing week number function to the calendar module
of the stdlib application. The implementation conforms to the ISO 8601 standard.
The new feature has been implemented tested and documented.

dialyzer spec.
|
|
Previous commit changed the supervisor to not save
parameter lists for temporary processes supervised by simple-one-for-one
supervisors. But it is unnecessary to save them for any
temporary processes as they should not be restarted. Proably the
biggest gain is in the simple-one-for-one case.
Also changed the test case count_children_memory so it does
not test that which_children will produce garbage that must
be reclaimed later. This is a strange thing to test and it is no
longer true for all invocations of which_children.

* egil/io-badarg/OTP-9045:
Fix exception generation in the io module
|
|
Some functions did not generate correct badarg exception on a
badarg exception.
Affected functions:
- io:put_chars/1,2
- io:nl/1
- io:write/1,2
- io:format/1,2,3
- io:fwrite/1,2,3
|
|
|
|
Did not properly take care of case when TryMeElse restarted
with next match clause.

In halfword emulator, make ETS use a variant of the internal term
format that uses relative offsets instead of absolute pointers. This
will allow storage in high memory (>4G). Preprocessor macros (like
list_val_rel(TERM,BASE)) are used to make normal (fullword) emulator
almost completely unchanged while still reusing most of the code.

Use a binary instead of a string for the help text.
|
|
Since the error messages in the erl_posix_msg module are
presumably used very seldom, save memory by using binaries
instead of strings.
