Since 1994 when the AUTOMATIC TAGS was introduced, ASN.1 users
no long need to worry about tagging, and the following sentence
no longer makes any sense:
It is essential for all users of ASN.1 to
understand all the details about tags.
Therefore, remove the entire existing section of tags, and replace
it with a shorter section explaining why we no longer need to know
about tags. Remove all tags from the examples.
|
|
Since the SET type is used exactly the same way as the SEQUENCE
type in Erlang, we can simply say so and note that decoding will
be less efficient for the BER and DER encoding rules.
|
|
It turns out that the current BER back-end can recognize complex
DEFAULT values, so I had to commit up with a more elaborate
example to show a difference between the BER and DER back-ends.
|
|
|
|
The decode functions now return a binary, not an iolist, so we must
both change the output and remove the call to list_to_binary when
decoding.
|
|
|
|
Replace "IMPLICIT TAGS" with "AUTOMATIC TAGS" since AUTOMATIC TAGS
is recommended for all new ASN.1 specifications.
|
|
We can assume that anyone that reads the documentation for the Asn1
documentation already knows about ASN.1, so we don't need three
paragraphs of introductory. Keep one short paragraph explaining
what ASN.1 is in case a reader unfamiliar with ASN.1 stumbles upon
the manual.
While we are at it, reformat the paragraphs in Introduction to
shorter lines that don't wrap.

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

This will also eliminate a dialyzer warning for unmatched returns,
and increase the coverage.
|
|
The error checking code for INTEGER and BIT STRING was broken,
since it built an error tuple that was never returned.
Rewrite the error checking code, sharing most of the code between
INTEGER and BIT STRING. Make sure that we test for both duplicated
names and number, as well as for negative bit numbers for
BIT STRING.
This rewrite will eliminate two dialyzer warnings for unmatched
returns.
|
|
A named number list as used for ENUMERATED and INTEGER can never
have an {identifier,...} tuple in its third position like this:
{'NamedNumber',Id,{identifier,_,_}}
because asn1ct_parser2:parse_NamedNumber/1 will always replace
an identifier tuple with an #Externaluereference{} record.
|
|
Since most calls to asn1_error/3 throw its result, it makes more
sense to let asn1_error/3 itself throw the error tuple. Add the
return_asn1_error/3 to return the error tuple to use when we don't
want to throw it.

This port has support for both non-smp and smp.
It contains a new way to do io checking in which erts_poll_wait
receives the payload of the polled entity. This has implications
for all linked-in drivers.

Commit e5c71b7 deprecated several all functions in the asn1rt
module. As a result, calls to those functions from test suites
caused warnings, and as the warnings_as_errors option was active,
two test files failed to compile.

Add the mentioned test suites for *all* library and touched
non-library applications.
|

Those asn1 functions are no longer needed because they all have
better alternatives.

As discussed in issue #240 *all* OTP library applications use the '.*'
wildcard as up and down version. This makes library applications
always up- and downgradeable. Using the wildcard version obsoletes
all maintenance tasks regarding library applications' appup files.
Additionally, it prevents upgrade problems caused by automatically
included application dependencies when using reltool to create
releases. Missing copyright headers are now consistently present.

Attempting to subtype an extensible ENUMERATED like this:
BaseType ::= { foo, bar, ... }
SubType ::= BaseType ( foo )
would fail to compile with a message that 'foo' was undefined.

Unfortunately the code in question is not covered by our test
suites, but it should be correct to do the same thing as in
the clause above.
|
|
check_integer/3 can check nothing for an INTEGER without any named
values. Remove the useless call to silence a dialyzer warning for
unmatched return.
|
|
The value for an OCTET STRING must be specified as either a bstring
or an hstring. Everything else (including character strings) is
illegal.
This correction also removes the offending code that caused an
unmatched return warning from dialyzer.
|
|
|
|
Unused flexibility complicates the code and can hide bugs.
new/1 is never called with a table name that already exists, so
we should remove the code that allows for that. That will increase
the coverage of asn1ct_table to 100%.
Also remove the new/2 and new_reuse/2 functions which are never
called externally.
|
|
Change the code so that delete/1 always returns 'true'.
While at it, also remove the TODO comment and explain in a comment
why we want to keep the delete/1 function.

This will silence a dialyzer warning for unmatched return.

strings in PER.

complete/1 is used when encoding open types (as well as in the
encode/2 function in a generated module).
The use of complete/1 for encoding open types used to be optimized
in two different places.
One place was in the alignment optimization pass, where we attempted
to replace the call to complete/1 with a call to iolist_to_binary/1.
That optimization was taken out in a previous commit that introduced
the {list,_,_} intermediate instruction.
The other place was when creating the intermediate representation
for the encoding of the open type. When attempting to wrap primitive
types in an open type, we would attempt to optimize the encoding of
the length decscriptor. We will remove that optimization in this
commit.
Since the previous two optimizations did not optimize encoding of
open types as much as we would want, we will introduce a new
optimization in a separate pass that will go further than the
previous optimizations.

The {list,List,Dst} instruction gives us as general way to
capture the building of something into a variable. That will make
inlining of intermediate code much easier.
It also allows us to eliminate the versions of the apply, call_gen,
and cond instructions that takes a target variable.
Also remove the optimization in the alignment optimization pass
that attempts to replace calls to complete/1 with calls to
iolist_to_binary/1. That optimization will not work anymore without
rewriting, so we will remove it in this commit and introcude a
more powerful optimization in a future commit.

Instead of generating:
{assign,Dst,"element(2, Val)"}
generate:
{call,erlang,element,[2,{var,"Val"}],Dst}
The latter expression is easier to understand since there is no
need to parse a string which may contain an arbitrary expression.
While at it, also discontinue the practice to treat "naked"
atoms as variables. A variable must always be given as {var,String}.
|
|
The {assign,Dst,Src} instruction is difficult to cope with when
doing advanced optimizations, since its source argument is a string
which may contain any expression.
Instead of changing how {assign,_,_} works, we will introduce new
instructions that can be used instead of {assign,_}, and remove
{assign,_,_} in a later commit when it is no longer used.
The first new instruction we will introduce is:
{set,{var,Src},{var,Dst}}
It is useful for common sub-expression elemination among other things.
For the moment, we will only allow a variable as a source argument,
but we could extend it in the future to allow constants as well.
