Subject: tv: Allow table viewer to display refs, ports and small binaries
Table viewer displayed #Port, #Ref, or #Bin as place holders for their
respective object types in ets and mnesia tables. This can make table
viewer difficult to use when viewing tables containing those data types.
It doesn't make sense to render large binaries so #Bin will still be
used for binaries that exceed 100 bytes.

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.

+-------------------------------
+To add test cases in any suite:
+-------------------------------
+
+ 1) If the test requires dialyzer to analyze a single file place it in the
+ suite's 'src' directory. If analysis of more files is needed place them
+ all in a new directory in suite's 'src' directory.
+
+ 2) Create a file with the same name as the test (if single file, omit the
+ extension else directory name) containing the expected result in suite's
+ 'result' directory.
+
+ 3) Run './remake ', where is the suite's name omitting
+ "_tests_SUITE".
+
+----------------------
+To create a new suite:
+----------------------
+
+ 1) Create a directory with the suffix 'tests_SUITE_data'. The name should
+ describe the suite.
+
+ 2) In the suite's directory create subdirectories 'src' and 'results' as
+ well as a 'dialyzer_options' file with the following content:
+
+ {dialyzer_options, List}.
+ {time_limit, Limit}.
+
+ where:
+
+ List = a list of dialyzer options. Common case will be something
+ like [{warnings, Warnings}], where Warnings is a list of valid
+ '-W' prefixed dialyzer options without the 'W' prefix (e.g.
+ '-Wfoo' would be declared as [{warnings, [foo]}].
+ Limit = the amount of time each test case is allowed to run. Must be
+ bigger than the time it takes the most time-consuming test to
+ finish.
+
+ Any of these lines may be missing. Default options list is empty and
+ default time limit is 1 minute.
+
+ 3) Add tests as described in previous section.
+
+ 4) Add the resulting suite's name in the Makefile's MODULES variable.

+%%% Purpose : Optimise jumps and remove unreachable code.
+
+-module(beam_jump).
+
+-export([module/2,module_labels/1,
+ is_unreachable_after/1,remove_unused_labels/1]).
+
+%%% The following optimisations are done:
+%%%
+%%% (1) This code with two identical instruction sequences
+%%%
+%%% L1:
+%%% L2:
+%%% . . .
+%%% L3:
+%%% L4:
+%%%
+%%% can be replaced with
+%%%
+%%% L1: jump L3
+%%% L2:
+%%% . . .
+%%% L3:
+%%% L4
+%%%
+%%% Note: The instruction sequence must end with an instruction
+%%% such as a jump that never transfers control to the instruction
+%%% following it.
+%%%
+%%% (2) case_end, if_end, and badmatch, and function calls that cause an
+%%% exit (such as calls to exit/1) are moved to the end of the function.
+%%% The purpose is to allow further optimizations at the place from
+%%% which the code was moved.
+%%%
+%%% (3) Any unreachable code is removed. Unreachable code is code after
+%%% jump, call_last and other instructions which never transfer control
+%%% to the following instruction. Code is unreachable up to the next
+%%% *referenced* label. Note that the optimisations below might
+%%% generate more possibilities for removing unreachable code.
+%%%
+%%% (4) This code:
+%%% L1: jump L2
+%%% . . .
+%%% L2: ...
+%%%
+%%% will be changed to
+%%%
+%%% jump L2
+%%% . . .
+%%% L1:
+%%% L2: ...
+%%%
+%%% If the jump is unreachable, it will be removed according to (1).
+%%%
+%%% (5) In
+%%%
+%%% jump L1
+%%% L1:
+%%%
+%%% the jump will be removed.
+%%%
+%%% (6) If test instructions are used to skip a single jump instruction,
+%%% the test is inverted and the jump is eliminated (provided that
+%%% the test can be inverted). Example:
+%%%
+%%% is_eq L1 {x,1} {x,2}
+%%% jump L2
+%%% L1:
+%%%
+%%% will be changed to
+%%%
+%%% is_ne L2 {x,1} {x,2}
+%%%
+%%% (The label L1 will be retained if there were previous references to it.)
+%%%
+%%% (7) Some redundant uses of is_boolean/1 is optimized away.
+%%%
+%%% Terminology note: The optimisation done here is called unreachable-code
+%%% elimination, NOT dead-code elimination. Dead code elimination
+%%% means the removal of instructions that are executed, but have no visible
+%%% effect on the program state.

+%% @doc Core Erlang abstract syntax trees.
+%%
+%% This module defines an abstract data type for representing Core
+%% Erlang source code as syntax trees.
+%%
+%% A recommended starting point for the first-time user is the
+%% documentation of the function type/1
.
+%%
+%% NOTES:
+%%
+%% This module deals with the composition and decomposition of
+%% syntactic entities (as opposed to semantic ones); its
+%% purpose is to hide all direct references to the data structures
+%% used to represent these entities. With few exceptions, the
+%% functions in this module perform no semantic interpretation of
+%% their inputs, and in general, the user is assumed to pass
+%% type-correct arguments - if this is not done, the effects are not
+%% defined.
+%%
+%% The internal representations of abstract syntax trees are
+%% subject to change without notice, and should not be documented
+%% outside this module. Furthermore, we do not give any guarantees on
+%% how an abstract syntax tree may or may not be represented, with
+%% the following exceptions: no syntax tree is represented by a
+%% single atom, such as none
, by a list constructor
+%% [X | Y]
, or by the empty list []
. This
+%% can be relied on when writing functions that operate on syntax
+%% trees.
+%%
+%% @type cerl(). An abstract Core Erlang syntax tree.
+%%
+%% Every abstract syntax tree has a type, given by the
+%% function type/1
. In addition,
+%% each syntax tree has a list of user annotations (cf. get_ann/1
), which are included
+%% in the Core Erlang syntax.

+%% Representation (general)
+%%
+%% All nodes are represented by tuples of arity 2 or (generally)
+%% greater, whose first element is an atom which uniquely identifies the
+%% type of the node, and whose second element is a (proper) list of
+%% annotation terms associated with the node - this is by default empty.
+%%
+%% For most node constructor functions, there are analogous functions
+%% named 'ann_...', taking one extra argument 'As' (always the first
+%% argument), specifying an annotation list at node creation time.
+%% Similarly, there are also functions named 'update_...', taking one
+%% extra argument 'Old', specifying a node from which all fields not
+%% explicitly given as arguments should be copied (generally, this is
+%% the annotation field only).
+%% =====================================================================
+
+%% This defines the general representation of constant literals:
+
+-record(literal, {ann = [], val}).
+
+
+%% @spec type(Node::cerl()) -> atom()
+%%
+%% @doc Returns the type tag of Node
. Current node types
+%% are:
+%%
+%%
+%%
+%% alias |
+%% apply |
+%% binary |
+%% bitstr |
+%% call |
+%% case |
+%% catch |
+%%
+%% clause |
+%% cons |
+%% fun |
+%% let |
+%% letrec |
+%% literal |
+%% module |
+%%
+%% primop |
+%% receive |
+%% seq |
+%% try |
+%% tuple |
+%% values |
+%% var |
+%%
+%%
+%%
+%% Note: The name of the primary constructor function for a node
+%% type is always the name of the type itself, prefixed by
+%% "c_
"; recognizer predicates are correspondingly
+%% prefixed by "is_c_
". Furthermore, to simplify
+%% preservation of annotations (cf. get_ann/1
), there are
+%% analogous constructor functions prefixed by "ann_c_
"

can be a

+%% your code is not overly sensitive to extensions of the syntax tree
+%% data type, because any node types not explicitly handled by your code
+%% can be left to a default case.
+%%
+%% For example:

+%% [] -> Tree;
+%% List -> update_tree(Tree,
+%% [[postorder(F, Subtree)
+%% || Subtree <- Group]
+%% || Group <- List])
+%% end).
+%%
+%% maps the function F
on Tree
and all its
+%% subtrees, doing a post-order traversal of the syntax tree. (Note

to preserve annotations.) For
+%% a simple function like:
+%%
+%% f(Node) ->
+%% case type(Node) of
+%% atom -> atom("a_" ++ atom_name(Node));
+%% _ -> Node
+%% end.
+%%
+%% the call postorder(fun f/1, Tree)

".

+%% - Matching pattern "
{X, {bar, Y}}

" yields {false,

where Bindings
associates

" with the subtree "foo
" and

" with any
(because it is not known

+%% - Matching pattern "
{foo, bar}
" against expression

" yields {false, []}

+%%
+%% - Matching
{foo, X = {bar, Y}}
against expression

+%% Normal execution times for inlining are between 0.1 and 0.3 seconds
+%% (on the author's current equipment). The default effort limit of 150
+%% is high enough that most normal programs never hit the limit even
+%% once, and for difficult programs, it generally keeps the execution
+%% times below 2-5 seconds. Using an effort counter of 1000 will thus
+%% have no further effect on most programs, but some programs may take
+%% as much as 10 seconds or more. Effort counts larger than 2500 have
+%% never been observed even on very ill-conditioned programs.
+%%
+%% Size limits between 6 and 18 tend to actually shrink the code,
+%% because of the simplifications made possible by inlining. A limit of
+%% 16 seems to be optimal for this purpose, often shrinking the
+%% executable code by up to 10%. Size limits between 18 and 30 generally
+%% give the same code size as if no inlining was done (i.e., code
+%% duplication balances out the simplifications at these levels). A size
+%% limit between 1 and 5 tends to inline small functions and propagate
+%% constants, but does not cause much simplifications do be done, so the
+%% net effect will be a slight increase in code size. For size limits
+%% above 30, the executable code size tends to increase with about 10%

+%% representation. The extension of the listing
+%% file will be Ext. (Ext should not contain
+%% a period.) No more passes will be run.
+%%
+%% {done,Ext} End compilation at this point. Produce a listing

+%% Purpose : Do necessary checking of Core Erlang code.
+
+%% Check Core module for errors. Seeing this module is used in the
+%% compiler after optimisations wedone more checking than would be
+%% necessary after just parsing. Don't check all constructs.
+%%
+%% We check the following:
+%%
+%% All referred functions, called and exported, are defined.
+%% Format of export list.
+%% Format of attributes
+%% Used variables are defined.
+%% Variables in let and funs.
+%% Patterns case clauses.
+%% Values only as multiple values/variables/patterns.
+%% Return same number of values as requested
+%% Correct number of arguments
+%%
+%% Checks to add:
+%%
+%% Consistency of values/variables
+%% Consistency of function return values/calls.
+%%
+%% We keep the names defined variables and functions in a ordered list
+%% of variable names and function name/arity pairs.

+%% =====================================================================
+%% The key-generating algorithm could possibly be further improved. The
+%% important thing to keep in mind is, that when we need a new key, we
+%% are generally in mid-traversal of a syntax tree, and existing names
+%% in the tree may be closely grouped and evenly distributed or even
+%% forming a compact range (often having been generated by a "gensym",
+%% or by this very algorithm itself). This means that if we generate an
+%% identifier whose value is too close to those already seen (i.e.,
+%% which are in the environment), it is very probable that we will
+%% shadow a not-yet-seen identifier further down in the tree, the result
+%% being that we induce another later renaming, and end up renaming most
+%% of the identifiers, completely contrary to our intention. We need to
+%% generate new identifiers in a way that avoids such systematic
+%% collisions.
+%%
+%% One way of getting a new key to try when the previous attempt failed
+%% is of course to e.g. add one to the last tried value. However, in
+%% general it's a bad idea to try adjacent identifiers: the percentage
+%% of retries will typically increase a lot, so you may lose big on the
+%% extra lookups while gaining only a little from the quicker
+%% computation.
+%%
+%% We want an initial range that is large enough for most typical cases.
+%% If we start with, say, a range of 10, we might quickly use up most of
+%% the values in the range 1-10 (or 1-100) for new top-level variables -
+%% but as we start traversing the syntax tree, it is quite likely that
+%% exactly those variables will be encountered again (this depends on
+%% how the names in the tree were created), and will then need to be
+%% renamed. If we instead begin with a larger range, it is less likely
+%% that any top-level names that we introduce will shadow names that we
+%% will find in the tree. Of course we cannot know how large is large
+%% enough: for any initial range, there is some syntax tree that uses
+%% all the values in that range, and thus any top-level names introduced
+%% will shadow names in the tree. The point is to avoid this happening
+%% all the time - a range of about 1000 seems enough for most programs.
+%%
+%% The following values have been shown to work well:
+
+-define(MINIMUM_RANGE, 1000).
+-define(START_RANGE_FACTOR, 50).
+-define(MAX_RETRIES, 2). % retries before enlarging range
+-define(ENLARGE_FACTOR, 10). % range enlargment factor

+%% If you want to use these process dictionary counters, make sure to
+%% initialise them to zero before you call any of the key-generating

+%% Purpose : Code generator for Beam.
+
+%% The following assumptions have been made:
+%%
+%% 1. Matches, i.e. things with {match,M,Ret} wrappers, only return
+%% values; no variables are exported. If the match would have returned
+%% extra variables then these have been transformed to multiple return
+%% values.
+%%
+%% 2. All BIF's called in guards are gc-safe so there is no need to
+%% put thing on the stack in the guard. While this would in principle
+%% work it would be difficult to keep track of the stack depth when
+%% trimming.
+%%
+%% The code generation uses variable lifetime information added by
+%% the v3_life module to save variables, allocate registers and
+%% move registers to the stack when necessary.
+%%
+%% We try to use a consistent variable name scheme throughout. The
+%% StackReg record is always called Bef,Int,Aft.

+%%
+%% Purpose : Transform normal Erlang to Core Erlang
+
+%% At this stage all preprocessing has been done. All that is left are
+%% "pure" Erlang functions.
+%%
+%% Core transformation is done in three stages:
+%%
+%% 1. Flatten expressions into an internal core form without doing
+%% matching.
+%%
+%% 2. Step "forwards" over the icore code annotating each "top-level"
+%% thing with variable usage. Detect bound variables in matching
+%% and replace with explicit guard test. Annotate "internal-core"
+%% expressions with variables they use and create. Convert matches
+%% to cases when not pure assignments.
+%%
+%% 3. Step "backwards" over icore code using variable usage
+%% annotations to change implicit exported variables to explicit
+%% returns.
+%%
+%% To ensure the evaluation order we ensure that all arguments are
+%% safe. A "safe" is basically a core_lib simple with VERY restricted
+%% binaries.
+%%
+%% We have to be very careful with matches as these create variables.
+%% While we try not to flatten things more than necessary we must make
+%% sure that all matches are at the top level. For this we use the
+%% type "novars" which are non-match expressions. Cases and receives
+%% can also create problems due to exports variables so they are not
+%% "novars" either. I.e. a novars will not export variables.
+%%
+%% Annotations in the #iset, #iletrec, and all other internal records
+%% is kept in a record, #a, not in a list as in proper core. This is
+%% easier and faster and creates no problems as we have complete control
+%% over all annotations.
+%%
+%% On output, the annotation for most Core Erlang terms will contain
+%% the source line number. A few terms will be marked with the atom
+%% atom 'compiler_generated', to indicate that the compiler has generated
+%% them and that no warning should be generated if they are optimized
+%% away.
+%%
+%%
+%% In this translation:
+%%
+%% call ops are safes
+%% call arguments are safes
+%% match arguments are novars
+%% case arguments are novars
+%% receive timeouts are novars
+%% let/set arguments are expressions
+%% fun is not a safe

+%%
+%% Purpose : Transform Core Erlang to Kernel Erlang
+
+%% Kernel erlang is like Core Erlang with a few significant
+%% differences:
+%%
+%% 1. It is flat! There are no nested calls or sub-blocks.
+%%
+%% 2. All variables are unique in a function. There is no scoping, or
+%% rather the scope is the whole function.
+%%
+%% 3. Pattern matching (in cases and receives) has been compiled.
+%%
+%% 4. The annotations contain variable usages. Seeing we have to work
+%% this out anyway for funs we might as well pass it on for free to
+%% later passes.
+%%
+%% 5. All remote-calls are to statically named m:f/a. Meta-calls are
+%% passed via erlang:apply/3.
+%%
+%% The translation is done in two passes:
+%%
+%% 1. Basic translation, translate variable/function names, flatten
+%% completely, pattern matching compilation.
+%%
+%% 2. Fun-lifting (lambda-lifting), variable usage annotation and
+%% last-call handling.
+%%
+%% All new Kexprs are created in the first pass, they are just
+%% annotated in the second.
+%%
+%% Functions and BIFs
+%%
+%% Functions are "call"ed or "enter"ed if it is a last call, their
+%% return values may be ignored. BIFs are things which are known to
+%% be internal by the compiler and can only be called, their return
+%% values cannot be ignored.
+%%
+%% Letrec's are handled rather naively. All the functions in one
+%% letrec are handled as one block to find the free variables. While
+%% this is not optimal it reflects how letrec's often are used. We
+%% don't have to worry about variable shadowing and nested letrec's as
+%% this is handled in the variable/function name translation. There
+%% is a little bit of trickery to ensure letrec transformations fit
+%% into the scheme of things.
+%%
+%% To ensure unique variable names we use a variable substitution
+%% table and keep the set of all defined variables. The nested
+%% scoping of Core means that we must also nest the substitution
+%% tables, but the defined set must be passed through to match the
+%% flat structure of Kernel and to make sure variables with the same
+%% name from different scopes get different substitutions.
+%%
+%% We also use these substitutions to handle the variable renaming
+%% necessary in pattern matching compilation.
+%%
+%% The pattern matching compilation assumes that the values of
+%% different types don't overlap. This means that as there is no
+%% character type yet in the machine all characters must be converted
+%% to integers!

+%% This code implements the algorithm for an optimizing compiler for
+%% pattern matching given "The Implementation of Functional
+%% Programming Languages" by Simon Peyton Jones. The code is much
+%% longer as the meaning of constructors is different from the book.
+%%
+%% In Erlang many constructors can have different values, e.g. 'atom'
+%% or 'integer', whereas in the original algorithm thse would be
+%% different constructors. Our view makes it easier in later passes to
+%% handle indexing over each type.
+%%
+%% Patterns are complicated by having alias variables. The form of a
+%% pattern is Pat | {alias,Pat,[AliasVar]}. This is hidden by access
+%% functions to pattern arguments but the code must be aware of it.
+%%
+%% The compilation proceeds in two steps:
+%%
+%% 1. The patterns in the clauses to converted to lists of kernel
+%% patterns. The Core clause is now hybrid, this is easier to work
+%% with. Remove clauses with trivially false guards, this simplifies
+%% later passes. Add local defined vars and variable subs to each
+%% clause for later use.
+%%
+%% 2. The pattern matching is optimised. Variable substitutions are
+%% added to the VarSub structure and new variables are made visible.

+%%
+%% Purpose : Convert annotated kernel expressions to annotated beam format.
+
+%% This module creates beam format annotated with variable lifetime
+%% information. Each thing is given an index and for each variable we
+%% store the first and last index for its occurrence. The variable
+%% database, VDB, attached to each thing is only relevant internally
+%% for that thing.
+%%
+%% For nested things like matches the numbering continues locally and
+%% the VDB for that thing refers to the variable usage within that
+%% thing. Variables which live through a such a thing are internally
+%% given a very large last index. Internally the indexes continue
+%% after the index of that thing. This creates no problems as the
+%% internal variable info never escapes and externally we only see
+%% variable which are alive both before or after.
+%%
+%% This means that variables never "escape" from a thing and the only
+%% way to get values from a thing is to "return" them, with 'break' or
+%% 'return'. Externally these values become the return values of the
+%% thing. This is no real limitation as most nested things have
+%% multiple threads so working out a common best variable usage is
+%% difficult.

+%% Note: This requires also that the ticket OTP-2928 is fixed on the nodes
+%% running vsn 1 or 2; if such nodes will coexist with vsn 3 nodes.

+%% Connection algorithm
+%% ====================
+%% This alg solves the problem with partitioned nets as well.
+%%
+%% The main idea in the alg is that when two nodes connect, they
+%% try to set a lock in their own partition (i.e. all nodes already
+%% known to them). When the lock is set in each partition, these
+%% two nodes send each other a list with all registered names in
+%% resp partition(*). If no conflict is found, the name tables are
+%% just updated. If a conflict is found, a resolve function is
+%% called once for each conflict. The result of the resolving
+%% is sent to the other node. When the names are exchanged, all
+%% other nodes in each partition are informed of the other nodes,
+%% and they ping each other to form a fully connected net.
+%%
+%% Here's the flow:
+%% Suppose nodes A and B connect, and C is connected to A.
+%%
+%% Node A
+%% ------
+%% << {nodeup, B}
+%% [spawn locker]
+%% B ! {init_connect, MyLocker}
+%% << {init_connect, MyLocker}
+%% [The lockers try to set the lock]
+%% << {lock_is_set, B}
+%% [Now, lock is set in both partitions]
+%% B ! {exchange, Names}
+%% << {exchange, Names}
+%% [solve conflict]
+%% B ! {resolved, Resolved}
+%% << {resolved, Resolved}
+%% C ! {new_nodes, Resolved, [B]}
+%%
+%% Node C
+%% ------
+%% << {new_nodes, ResolvedOps, NewNodes}
+%% [insert Ops]
+%% ping(NewNodes)
+%% << {nodeup, B}
+%%
+%%
+%% Several things can disturb this picture.
+%%
+%% First, the got_names message may arrive *before* the nodeup
+%% message, due to delay in net_kernel and an optimisation in the
+%% emulator. We handle this by keeping track of these messages in the
+%% pre_connect and lockers variables in our state.
+%%
+%% The most common situation is when a new node connects to an
+%% existing net. In this case there's no need to set the lock on
+%% all nodes in the net, as we know that there won't be any conflict.
+%% This is optimised by sending {first_contact, Node} instead of got_names.
+%% This implies that first_contact may arrive before nodeup as well.
+%%
+%% Of course we must handle that some node goes down during the
+%% connection.
+%%
+%% (*) When this information is being exchanged, no one is allowed
+%% to change the global register table. All calls to register etc
+%% are protected by a lock. If a registered process dies
+%% during this phase, the deregistration is done as soon as possible
+%% on each node (i.e. when the info about the process has arrived).
+%%-----------------------------------------------------------------
+%% Messages in the protocol
+%% ========================
+%% 1. Between connecting nodes (gen_server:casts)
+%% {init_connect, Vsn, Node, InitMsg}
+%% InitMsg = {locker, LockerPid}
+%% {exchange, Node, ListOfNames}
+%% {resolved, Node, Ops, Known}
+%% Known = list of nodes in Node's partition
+%% 2. Between lockers on connecting nodes (!s)
+%% {his_locker, Pid} (from our global)
+%% lockers link to each other
+%% {lock, Bool} loop until both lockers have lock = true,
+%% then send to global {lock_is_set, Node}
+%% 3. From connecting node to other nodes in the partition
+%% {new_nodes, Node, Ops, NewNodes}
+%% 4. sync protocol
+%% {in_sync, Node, IsKnown}
+%% - sent by each node to all new nodes

+%%-----------------------------------------------------------------
+%% A locker is a process spawned by global_name_server when a
+%% nodeup is received from a new node. Its purpose is to try to
+%% set a lock in our partition, i.e. on all nodes known to us.
+%% When the lock is set, it tells global about it, and keeps
+%% the lock set. global sends a cancel message to the locker when
+%% the partitions are connected.
+
+%% Versions: at version 2, the messages exchanged between the lockers
+%% include the known nodes (see OTP-3576). There is no way of knowing
+%% the version number of the other side's locker when sending a message
+%% to it, so we send both version 1 and 2, and flush the version 1 if
+%% we receive version 2.
+%%
+%% Due to a mistake, an intermediate version of the new locking protocol
+%% (using 3-tuples) went out in R7, which only understands itself. This patch
+%% to R7 handles all kinds, which means sending all, and flush the ones we
+%% don't want. (It will remain difficult to make a future version of the
+%% protocol communicate with this one.)

+The following restrictions apply to this implementation of the ASN.1 compiler:
+
+Supported encoding rules are:
+BER
+PER (aligned)
+
+PER (unaligned) IS NOT SUPPORTED
+
+Supported types are:
+
+INTEGER
+BOOLEAN
+ENUMERATION
+SEQUENCE
+SEQUENCE OF
+SET
+SET OF
+CHOICE
+OBJECT IDENTIFIER
+RestrictedCharacterStringTypes
+UnrestrictedCharacterStringTypes
+
+
+NOT SUPPORTED types are:
+ANY IS (IS NOT IN THE STANDARD ANY MORE)
+ANY DEFINED BY (IS NOT IN THE STANDARD ANY MORE)
+EXTERNAL
+EMBEDDED-PDV
+REAL
+
+The support for value definitions in the ASN.1 notation is very limited.
+
+The support for constraints is limited to:
+SizeConstraint SIZE(X)
+SingleValue (1)
+ValueRange (X..Y)
+PermittedAlpabet FROM
+
+The only supported value-notation for SEQUENCE and SET in Erlang is
+the record variant.
+The list notation with named components used by the old ASN.1 compiler
+was supported in the first versions of this compiler both are no longer
+supported.
+
+The decode functions always return a symbolic value if they can.
+
+
+Files with ASN.1 source must have a suffix .asn1 the suffix .py used by the
+old ASN.1 compiler is supported in this version but will not be supported in the future.
+
+Generated files:
+X.asn1db % the intermediate format of a compiled ASN.1 module
+X.hrl % generated Erlang include file for module X
+X.erl % generated Erlang module with encode decode functions for
+ % ASN.1 module X

+ ASN1 Release Notes (Old)
+ Kenneth Lundin

+ 98-02-02
+ A
+ notes_history.sgml
+
+
+ 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.
+

+%% PARSING OF RESULT LINES
+%%
+
+%% Excerpt from RFC 959:
+%%
+%% "A reply is defined to contain the 3-digit code, followed by Space
+%% , followed by one line of text (where some maximum line length
+%% has been specified), and terminated by the Telnet end-of-line
+%% code. There will be cases however, where the text is longer than
+%% a single line. In these cases the complete text must be bracketed
+%% so the User-process knows when it may stop reading the reply (i.e.
+%% stop processing input on the control connection) and go do other
+%% things. This requires a special format on the first line to
+%% indicate that more than one line is coming, and another on the
+%% last line to designate it as the last. At least one of these must
+%% contain the appropriate reply code to indicate the state of the
+%% transaction. To satisfy all factions, it was decided that both
+%% the first and last line codes should be the same.
+%%
+%% Thus the format for multi-line replies is that the first line
+%% will begin with the exact required reply code, followed
+%% immediately by a Hyphen, "-" (also known as Minus), followed by
+%% text. The last line will begin with the same code, followed
+%% immediately by Space , optionally some text, and the Telnet
+%% end-of-line code.
+%%
+%% For example:
+%% 123-First line
+%% Second line
+%% 234 A line beginning with numbers
+%% 123 The last line
+%%
+%% The user-process then simply needs to search for the second
+%% occurrence of the same reply code, followed by (Space), at
+%% the beginning of a line, and ignore all intermediary lines. If
+%% an intermediary line begins with a 3-digit number, the Server
+%% must pad the front to avoid confusion.
+%%
+%% This scheme allows standard system routines to be used for
+%% reply information (such as for the STAT reply), with
+%% "artificial" first and last lines tacked on. In rare cases
+%% where these routines are able to generate three digits and a
+%% Space at the beginning of any line, the beginning of each
+%% text line should be offset by some neutral text, like Space.
+%%
+%% This scheme assumes that multi-line replies may not be nested."
+
+%% We have to collect the stream of result characters into lines (ending
+%% in "\r\n"; we check for "\n"). When a line is assembled, left-over
+%% characters are saved in the process dictionary.

+%%% This version of the HTTP/1.1 client implements:
+%%% - RFC 2616 HTTP 1.1 client part
+%%% - RFC 2817 Upgrading to TLS Within HTTP/1.1 (not yet!)
+%%% - RFC 2818 HTTP Over TLS
+%%% - RFC 3229 Delta encoding in HTTP (not yet!)
+%%% - RFC 3230 Instance Digests in HTTP (not yet!)
+%%% - RFC 3310 Authentication and Key Agreement (AKA) (not yet!)
+%%% - HTTP/1.1 Specification Errata found at
+%%% http://world.std.com/~lawrence/http_errata.html
+%%% Additionaly follows the following recommendations:
+%%% - RFC 3143 Known HTTP Proxy/Caching Problems (not yet!)
+%%% - draft-nottingham-hdrreg-http-00.txt (not yet!)
+%%%
+%%% Depends on
+%%% - uri.erl for all URL parsing (except what is handled by the C driver)
+%%% - http_lib.erl for all parsing of body and headers
+%%%
+%%% Supported Settings are:
+%%% http_timeout % (int) Milliseconds before a request times out
+%%% http_useproxy % (bool) True if a proxy should be used
+%%% http_proxy % (string) Proxy
+%%% http_noproxylist % (list) List with hosts not requiring proxy
+%%% http_autoredirect % (bool) True if automatic redirection on 30X responses
+%%% http_ssl % (list) SSL settings. A non-empty list enables SSL/TLS
+%%% support in the HTTP client
+%%% http_pipelinesize % (int) Length of pipeline. 1 means no pipeline.
+%%% Only has effect when initiating a new session.
+%%% http_sessions % (int) Max number of open sessions for {Addr,Port}
+%%%
+%%% TODO: (Known bugs!)
+%% - Cache handling
+%% - Doesn't handle a bunch of entity headers properly
+%% - Better handling of status codes different from 200,30X and 50X
+%% - Many of the settings above are not implemented!
+%% - close_session/2 and cancel_request/1 doesn't work
+%% - Variable pipe size.
+%% - Due to the fact that inet_drv only has a single timer, the timeouts given
+%% for pipelined requests are not ok (too long)
+%%
+%% Note:
+%% - Some servers (e.g. Microsoft-IIS/5.0) may sometimes not return a proper
+%% 'Location' header on a redirect.
+%% The client will fail with {error,no_scheme} in these cases.

+%%%
+%%% Description: This function is used to block an HTTP server.
+%%% The blocking can be done in two ways,
+%%% disturbing or non-disturbing. Default is disturbing.
+%%% When a HTTP server is blocked, all requests are rejected
+%%% (status code 503).
+%%%
+%%% disturbing:
+%%% By performing a disturbing block, the server
+%%% is blocked forcefully and all ongoing requests
+%%% are terminated. No new connections are accepted.
+%%% If a timeout time is given then, on-going requests
+%%% are given this much time to complete before the
+%%% server is forcefully blocked. In this case no new
+%%% connections is accepted.
+%%%
+%%% non-disturbing:
+%%% A non-disturbing block is more gracefull. No
+%%% new connections are accepted, but the ongoing
+%%% requests are allowed to complete.
+%%% If a timeout time is given, it waits this long before
+%%% giving up (the block operation is aborted and the
+%%% server state is once more not-blocked).
