From 98de31e836a04ccc8f5f9acd90b9ba0803a24ab5 Mon Sep 17 00:00:00 2001 From: Stavros Aronis Date: Fri, 18 Jun 2010 03:44:25 +0300 Subject: Test suites for Dialyzer This is a transcription of most of the cvs.srv.it.uu.se:/hipe repository dialyzer_tests into test suites that use the test server framework. See README for information on how to use the included scripts for modifications and updates. When testing Dialyzer it's important that several OTP modules are included in the plt. The suites takes care of that too. --- .../test/r9c_tests_SUITE_data/src/asn1/Makefile | 151 + .../r9c_tests_SUITE_data/src/asn1/Restrictions.txt | 55 + .../r9c_tests_SUITE_data/src/asn1/asn1.app.src

+ +

This document describes the changes made to old versions of the asn1 application. + +

+ ASN1 0.8.1 +

This is the first release of the ASN1 application. This version is released + for beta-testing. Some functionality will be added until the 1.0 version is + released. A list of missing features and restrictions can be found in the + chapter below. + +

+ Missing features and other restrictions + + +

The encoding rules BER and PER (aligned) is supported. PER (unaligned) + IS NOT SUPPORTED. + +

NOT SUPPORTED types ANY and ANY DEFINED BY + (is not in the standard any more). + +

NOT SUPPORTED types EXTERNAL and EMBEDDED-PDV. + +

NOT SUPPORTED type REAL (planned to be implemented). + +

The code generation support for value definitions in the ASN.1 notation is very limited + (planned to be enhanced). + +

The support for constraints is limited to: + +

+ SizeConstraint SIZE(X) +

+ SingleValue (1) +

+ ValueRange (X..Y) +

+ PermittedAlpabet FROM (but not for BMPString and UniversalString when generating PER). + +

Complex expressions in constraints is not supported (planned to be extended). + +

The current version of the compiler has very limited error checking: + +

Stops at first syntax error. +

Does not stop when a reference to an undefined type is found , + but prints an error message. Compilation of the generated + Erlang module will then fail. +

A whole number of other semantical controls is currently missing. This + means that the compiler will give little or bad help to detect what's wrong + with an ASN.1 specification, but will mostly work very well when the + ASN.1 specification is correct. + + +

The maximum INTEGER supported in this version is a signed 64 bit integer. This + limitation is probably quite reasonable. (Planned to be extended). + +

Only AUTOMATIC TAGS supported for PER. + +

Only EXPLICIT and IMPLICIT TAGS supported for BER. + +

The compiler supports decoding of BER-data with indefinite length but it is + not possible to produce data with indefinite length with the encoder. + +

+ SingleValue (1) +

+ ValueRange (X..Y) +

+ PermittedAlpabet FROM (but not for BMPString and UniversalString when generating PER). + +

Complex expressions in constraints is not supported (planned to be extended). + +

The current version of the compiler has very limited error checking: + +

Stops at first syntax error. +

Does not stop when a reference to an undefined type is found , + but prints an error message. Compilation of the generated + Erlang module will then fail. +

A whole number of other semantical controls is currently missing. This + means that the compiler will give little or bad help to detect what's wrong + with an ASN.1 specification, but will mostly work very well when the + ASN.1 specification is correct. + + +

The maximum INTEGER supported in this version is a signed 64 bit integer. This + limitation is probably quite reasonable. (Planned to be extended). + +

Only AUTOMATIC TAGS supported for PER. + +

Only EXPLICIT and IMPLICIT TAGS supported for BER. + +

The compiler supports decoding of BER-data with indefinite length but it is + not possible to produce data with indefinite length with the encoder. + +
