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.

Depending on the type of Node, the size of some +%% groups may be variable (e.g., the group consisting of all the +%% elements of a tuple), while others always contain the same number +%% of elements - usually exactly one (e.g., the group containing the +%% argument expression of a case-expression). Note, however, that the +%% exact structure of the returned list (for a given node type) should +%% in general not be depended upon, since it might be subject to +%% change without notice.

+%% +%%

The function subtrees/1 and the constructor functions +%% make_tree/2 and update_tree/2 can be a +%% great help if one wants to traverse a syntax tree, visiting all its +%% subtrees, but treat nodes of the tree in a uniform way in most or all +%% cases. Using these functions makes this simple, and also assures that +%% 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: +%% 

+%%   postorder(F, Tree) ->
+%%       F(case subtrees(Tree) of
+%%           [] -> 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 +%% the use of update_tree/2 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) will yield a new +%% representation of Tree in which all atom names have +%% been extended with the prefix "a_", but nothing else (including +%% annotations) has been changed.

The expression represented +%% by MetaTree is implementation independent +%% with regard to the data structures used by the abstract syntax tree +%% implementation. +%% +%%

Any node in Tree whose node type is +%% var (cf. type/1), and whose list of +%% annotations (cf. get_ann/1) contains the atom +%% meta_var, will remain unchanged in the resulting tree, +%% except that exactly one occurrence of meta_var is +%% removed from its annotation list.

+%% +%%

The main use of the function meta/1 is to transform +%% a data structure Tree, which represents a piece of +%% program code, into a form that is representation independent +%% when printed. E.g., suppose Tree represents a +%% variable named "V". Then (assuming a function print/1 +%% for printing syntax trees), evaluating +%% print(abstract(Tree)) - simply using +%% abstract/1 to map the actual data structure onto a +%% syntax tree representation - would output a string that might look +%% something like "{var, ..., 'V'}", which is obviously +%% dependent on the implementation of the abstract syntax trees. This +%% could e.g. be useful for caching a syntax tree in a file. However, +%% in some situations like in a program generator generator (with two +%% "generator"), it may be unacceptable. Using +%% print(meta(Tree)) instead would output a +%% representation independent syntax tree generating +%% expression; in the above case, something like +%% "cerl:c_var('V')".

Examples: +%%

    +%%

    • +%% +%%
  • Matching pattern "{foo, bar}" against expression +%% "{foo, f()}" yields {false, []}, +%% telling us that there might be a match, but we cannot deduce any +%% bindings.
    • +%% +%%
  • Matching {foo, X = {bar, Y}} against expression +%% "{foo, {bar, baz}}" yields {true, +%% Bindings} where Bindings associates +%% "Y" with "baz", and "X" +%% with "{bar, baz}".

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 + +-ifdef(DEBUG). +%% If you want to use these process dictionary counters, make sure to +%% initialise them to zero before you call any of the key-generating +%% functions. +%% +%% new_key_calls total number of calls +%% new_key_retries failed key generation attempts +%% new_key_max maximum generated integer value +%% +-define(measure_calls(), + put(new_key_calls, 1 + get(new_key_calls))). +-define(measure_max_key(N), + case N > get(new_key_max) of + true -> + put(new_key_max, N); + false -> + ok + end). +-define(measure_retries(N), + put(new_key_retries, get(new_key_retries) + N)). +-else. +-define(measure_calls(), ok). +-define(measure_max_key(N), ok). +-define(measure_retries(N), ok). +-endif. + + +%% ===================================================================== +%% @spec new_key(Env::environment()) -> integer() +%% +%% @doc Returns an integer which is not already used as key in the +%% environment.

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 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 + +-module(v3_core). + +-export([module/2,format_error/1]). + +-import(lists, [map/2,foldl/3,foldr/3,mapfoldl/3,splitwith/2]). +-import(ordsets, [add_element/2,del_element/2,is_element/2, + union/1,union/2,intersection/2,subtract/2]). + +-include("core_parse.hrl"). + +-record(a, {us=[],ns=[],anno=[]}). %Internal annotation + +%% Internal core expressions and help functions. +%% N.B. annotations fields in place as normal Core expressions. + +-record(iset, {anno=#a{},var,arg}). +-record(iletrec, {anno=#a{},defs,body}). +-record(imatch, {anno=#a{},pat,guard=[],arg,fc}). +-record(icase, {anno=#a{},args,clauses,fc}). +-record(iclause, {anno=#a{},pats,pguard=[],guard,body}). +-record(ifun, {anno=#a{},id,vars,clauses,fc}). +-record(iapply, {anno=#a{},op,args}). +-record(icall, {anno=#a{},module,name,args}). +-record(iprimop, {anno=#a{},name,args}). +-record(itry, {anno=#a{},args,vars,body,evars,handler}). +-record(icatch, {anno=#a{},body}). +-record(ireceive1, {anno=#a{},clauses}). +-record(ireceive2, {anno=#a{},clauses,timeout,action}). +-record(iprotect, {anno=#a{},body}). +-record(ibinary, {anno=#a{},segments}). %Not used in patterns. + +-record(core, {vcount=0, %Variable counter + fcount=0, %Function counter + ws=[]}). %Warnings. + +module({Mod,Exp,Forms}, _Opts) -> + Cexp = map(fun ({N,A}) -> #c_fname{id=N,arity=A} end, Exp), + {Kfs,As,Ws} = foldr(fun form/2, {[],[],[]}, Forms), + {ok,#c_module{name=#c_atom{val=Mod},exports=Cexp,attrs=As,defs=Kfs},Ws}. + +form({function,_,_,_,_}=F0, {Fs,As,Ws0}) -> + {F,Ws} = function(F0, Ws0), + {[F|Fs],As,Ws}; +form({attribute,_,_,_}=F, {Fs,As,Ws}) -> + {Fs,[attribute(F)|As],Ws}. + +attribute({attribute,_,Name,Val}) -> + #c_def{name=core_lib:make_literal(Name), + val=core_lib:make_literal(Val)}. + +function({function,_,Name,Arity,Cs0}, Ws0) -> + %%ok = io:fwrite("~p - ", [{Name,Arity}]), + St0 = #core{vcount=0,ws=Ws0}, + {B0,St1} = body(Cs0, Arity, St0), + %%ok = io:fwrite("1", []), + %%ok = io:fwrite("~w:~p~n", [?LINE,B0]), + {B1,St2} = ubody(B0, St1), + %%ok = io:fwrite("2", []), + %%ok = io:fwrite("~w:~p~n", [?LINE,B1]), + {B2,#core{ws=Ws}} = cbody(B1, St2), + %%ok = io:fwrite("3~n", []), + {#c_def{name=#c_fname{id=Name,arity=Arity},val=B2},Ws}. + +body(Cs0, Arity, St0) -> + Anno = [element(2, hd(Cs0))], + {Args,St1} = new_vars(Anno, Arity, St0), + {Cs1,St2} = clauses(Cs0, St1), + {Ps,St3} = new_vars(Arity, St2), %Need new variables here + Fc = fail_clause(Ps, #c_tuple{es=[#c_atom{val=function_clause}|Ps]}), + {#ifun{anno=#a{anno=Anno},id=[],vars=Args,clauses=Cs1,fc=Fc},St3}. + +%% clause(Clause, State) -> {Cclause,State} | noclause. +%% clauses([Clause], State) -> {[Cclause],State}. +%% Convert clauses.

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.

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. + +-module(v3_life). + +-export([module/2]). + +-export([vdb_find/2]). + +-import(lists, [map/2,foldl/3]). +-import(ordsets, [add_element/2,intersection/2,union/2,union/1]). + +-include("v3_kernel.hrl"). +-include("v3_life.hrl"). + +%% These are not defined in v3_kernel.hrl. +get_kanno(Kthing) -> element(2, Kthing). +%%set_kanno(Kthing, Anno) -> setelement(2, Kthing, Anno). + +module(#k_mdef{name=M,exports=Es,attributes=As,body=Fs0}, Opts) -> + put(?MODULE, Opts), + Fs1 = map(fun function/1, Fs0), + erase(?MODULE), + {ok,{M,Es,As,Fs1}}. + +%% function(Kfunc) -> Func. + +function(#k_fdef{func=F,arity=Ar,vars=Vs,body=Kb}) -> + %%ok = io:fwrite("life ~w: ~p~n", [?LINE,{F,Ar}]), + As = var_list(Vs), + Vdb0 = foldl(fun ({var,N}, Vdb) -> new_var(N, 0, Vdb) end, [], As), + %% Force a top-level match! + B0 = case Kb of + #k_match{} -> Kb; + _ -> + Ka = get_kanno(Kb), + #k_match{anno=#k{us=Ka#k.us,ns=[],a=Ka#k.a}, + vars=Vs,body=Kb,ret=[]} + end, + {B1,_,Vdb1} = body(B0, 1, Vdb0), + {function,F,Ar,As,B1,Vdb1}. + +%% body(Kbody, I, Vdb) -> {[Expr],MaxI,Vdb}. +%% Handle a body, need special cases for transforming match_fails. +%% We KNOW that they only occur last in a body. + +body(#k_seq{arg=#k_put{anno=Pa,arg=Arg,ret=[R]}, + body=#k_enter{anno=Ea,op=#k_internal{name=match_fail,arity=1}, + args=[R]}}, + I, Vdb0) -> + Vdb1 = use_vars(Pa#k.us, I, Vdb0), %All used here + {[match_fail(Arg, I, Pa#k.a ++ Ea#k.a)],I,Vdb1}; +body(#k_enter{anno=Ea,op=#k_internal{name=match_fail,arity=1},args=[Arg]}, + I, Vdb0) -> + Vdb1 = use_vars(Ea#k.us, I, Vdb0), + {[match_fail(Arg, I, Ea#k.a)],I,Vdb1}; +body(#k_seq{arg=Ke,body=Kb}, I, Vdb0) -> + %%ok = io:fwrite("life ~w:~p~n", [?LINE,{Ke,I,Vdb0}]), + A = get_kanno(Ke), + Vdb1 = use_vars(A#k.us, I, new_vars(A#k.ns, I, Vdb0)), + {Es,MaxI,Vdb2} = body(Kb, I+1, Vdb1), + E = expr(Ke, I, Vdb2), + {[E|Es],MaxI,Vdb2}; +body(Ke, I, Vdb0) -> + %%ok = io:fwrite("life ~w:~p~n", [?LINE,{Ke,I,Vdb0}]), + A = get_kanno(Ke), + Vdb1 = use_vars(A#k.us, I, new_vars(A#k.ns, I, Vdb0)), + E = expr(Ke, I, Vdb1), + {[E],I,Vdb1}. + +%% guard(Kguard, I, Vdb) -> Guard. + +guard(#k_try{anno=A,arg=Ts,vars=[#k_var{name=X}],body=#k_var{name=X}, + handler=#k_atom{val=false},ret=Rs}, I, Vdb) -> + %% Lock variables that are alive before try and used afterwards. + %% Don't lock variables that are only used inside the try expression. + Pdb0 = vdb_sub(I, I+1, Vdb), + {T,MaxI,Pdb1} = guard_body(Ts, I+1, Pdb0), + Pdb2 = use_vars(A#k.ns, MaxI+1, Pdb1), %Save "return" values + #l{ke={protected,T,var_list(Rs)},i=I,a=A#k.a,vdb=Pdb2}; +guard(#k_seq{}=G, I, Vdb0) -> + {Es,_,Vdb1} = guard_body(G, I, Vdb0), + #l{ke={block,Es},i=I,vdb=Vdb1,a=[]}; +guard(G, I, Vdb) -> guard_expr(G, I, Vdb). + +%% guard_body(Kbody, I, Vdb) -> {[Expr],MaxI,Vdb}. + +guard_body(#k_seq{arg=Ke,body=Kb}, I, Vdb0) -> + A = get_kanno(Ke), + Vdb1 = use_vars(A#k.us, I, new_vars(A#k.ns, I, Vdb0)), + {Es,MaxI,Vdb2} = guard_body(Kb, I+1, Vdb1), + E = guard_expr(Ke, I, Vdb2), + {[E|Es],MaxI,Vdb2}; +guard_body(Ke, I, Vdb0) -> + A = get_kanno(Ke), + Vdb1 = use_vars(A#k.us, I, new_vars(A#k.ns, I, Vdb0)), + E = guard_expr(Ke, I, Vdb1), + {[E],I,Vdb1}. + +%% guard_expr(Call, I, Vdb) -> Expr + +guard_expr(#k_test{anno=A,op=Op,args=As}, I, _Vdb) -> + #l{ke={test,test_op(Op),atomic_list(As)},i=I,a=A#k.a}; +guard_expr(#k_bif{anno=A,op=Op,args=As,ret=Rs}, I, _Vdb) -> + #l{ke={bif,bif_op(Op),atomic_list(As),var_list(Rs)},i=I,a=A#k.a}; +guard_expr(#k_put{anno=A,arg=Arg,ret=Rs}, I, _Vdb) -> + #l{ke={set,var_list(Rs),literal(Arg)},i=I,a=A#k.a}; +guard_expr(#k_match{anno=A,body=Kb,ret=Rs}, I, Vdb) -> + %% Experimental support for andalso/orelse in guards. + %% Work out imported variables which need to be locked. + Mdb = vdb_sub(I, I+1, Vdb), + M = match(Kb, A#k.us, I+1, Mdb), + #l{ke={match,M,var_list(Rs)},i=I,vdb=use_vars(A#k.us, I+1, Mdb),a=A#k.a}; +guard_expr(G, I, Vdb) -> guard(G, I, Vdb). + +%% expr(Kexpr, I, Vdb) -> Expr. + +expr(#k_call{anno=A,op=Op,args=As,ret=Rs}, I, _Vdb) -> + #l{ke={call,call_op(Op),atomic_list(As),var_list(Rs)},i=I,a=A#k.a}; +expr(#k_enter{anno=A,op=Op,args=As}, I, _Vdb) -> + #l{ke={enter,call_op(Op),atomic_list(As)},i=I,a=A#k.a}; +expr(#k_bif{anno=A,op=Op,args=As,ret=Rs}, I, _Vdb) -> + Bif = k_bif(A, Op, As, Rs), + #l{ke=Bif,i=I,a=A#k.a}; +expr(#k_match{anno=A,body=Kb,ret=Rs}, I, Vdb) -> + %% Work out imported variables which need to be locked. + Mdb = vdb_sub(I, I+1, Vdb), + M = match(Kb, A#k.us, I+1, Mdb), + #l{ke={match,M,var_list(Rs)},i=I,vdb=use_vars(A#k.us, I+1, Mdb),a=A#k.a}; +expr(#k_try{anno=A,arg=Ka,vars=Vs,body=Kb,evars=Evs,handler=Kh,ret=Rs}, I, Vdb) -> + %% Lock variables that are alive before the catch and used afterwards. + %% Don't lock variables that are only used inside the try. + Tdb0 = vdb_sub(I, I+1, Vdb), + %% This is the tricky bit.

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.

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_" -%% and "update_c_", for setting the annotation list of -%% the new node to either a specific value or to the annotations of an -%% existing node, respectively.

-%% -%%

When printing variable names, they must have the form of proper -%% Core Erlang variables and function names.

The function subtrees/1 and the constructor functions -%% make_tree/2 and update_tree/2 can be a -%% great help if one wants to traverse a syntax tree, visiting all its -%% subtrees, but treat nodes of the tree in a uniform way in most or all -%% cases. Using these functions makes this simple, and also assures that -%% 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: -%% 

-%%   postorder(F, Tree) ->
-%%       F(case subtrees(Tree) of
-%%           [] -> 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 -%% the use of update_tree/2 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) will yield a new -%% representation of Tree in which all atom names have -%% been extended with the prefix "a_", but nothing else (including -%% annotations) has been changed.

The result -%% represents an Erlang expression "MetaTree" -%% which, if evaluated, will yield a new syntax tree representing the -%% same source code text as Tree (although the actual -%% data representation may be different). The expression represented -%% by MetaTree is implementation independent -%% with regard to the data structures used by the abstract syntax tree -%% implementation. -%% -%%

Any node in Tree whose node type is -%% var (cf. type/1), and whose list of -%% annotations (cf. get_ann/1) contains the atom -%% meta_var, will remain unchanged in the resulting tree, -%% except that exactly one occurrence of meta_var is -%% removed from its annotation list.

-%% -%%

The main use of the function meta/1 is to transform -%% a data structure Tree, which represents a piece of -%% program code, into a form that is representation independent -%% when printed. E.g., suppose Tree represents a -%% variable named "V". Then (assuming a function print/1 -%% for printing syntax trees), evaluating -%% print(abstract(Tree)) - simply using -%% abstract/1 to map the actual data structure onto a -%% syntax tree representation - would output a string that might look -%% something like "{var, ..., 'V'}", which is obviously -%% dependent on the implementation of the abstract syntax trees. This -%% could e.g. be useful for caching a syntax tree in a file. However, -%% in some situations like in a program generator generator (with two -%% "generator"), it may be unacceptable. Using -%% print(meta(Tree)) instead would output a -%% representation independent syntax tree generating -%% expression; in the above case, something like -%% "cerl:c_var('V')".

    • -%% -%%
  • Matching pattern "{foo, bar}" against expression -%% "{foo, f()}" yields {false, []}, -%% telling us that there might be a match, but we cannot deduce any -%% bindings.
    • -%% -%%
  • Matching {foo, X = {bar, Y}} against expression -%% "{foo, {bar, baz}}" yields {true, -%% Bindings} where Bindings associates -%% "Y" with "baz", and "X" -%% with "{bar, baz}".

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 - --ifdef(DEBUG). -%% If you want to use these process dictionary counters, make sure to -%% initialise them to zero before you call any of the key-generating -%% functions. -%% -%% new_key_calls total number of calls -%% new_key_retries failed key generation attempts -%% new_key_max maximum generated integer value -%% --define(measure_calls(), - put(new_key_calls, 1 + get(new_key_calls))). --define(measure_max_key(N), - case N > get(new_key_max) of - true -> - put(new_key_max, N); - false -> - ok - end). --define(measure_retries(N), - put(new_key_retries, get(new_key_retries) + N)). --else. --define(measure_calls(), ok). --define(measure_max_key(N), ok). --define(measure_retries(N), ok). --endif. - - -%% ===================================================================== -%% @spec new_key(Env::environment()) -> integer() -%% -%% @doc Returns an integer which is not already used as key in the -%% environment.

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.

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! - --module(v3_kernel). - --export([module/2,format_error/1]). - --import(lists, [map/2,foldl/3,foldr/3,mapfoldl/3,splitwith/2, - member/2,reverse/1,reverse/2]). --import(ordsets, [add_element/2,del_element/2,union/2,union/1,subtract/2]). - --include("core_parse.hrl"). --include("v3_kernel.hrl"). - -%% These are not defined in v3_kernel.hrl. -get_kanno(Kthing) -> element(2, Kthing). -set_kanno(Kthing, Anno) -> setelement(2, Kthing, Anno). - -%% Internal kernel expressions and help functions. -%% N.B. the annotation field is ALWAYS the first field! - --record(ivalues, {anno=[],args}). --record(ifun, {anno=[],vars,body}). --record(iset, {anno=[],vars,arg,body}). --record(iletrec, {anno=[],defs}). --record(ialias, {anno=[],vars,pat}). --record(iclause, {anno=[],sub,pats,guard,body}). --record(ireceive_accept, {anno=[],arg}). --record(ireceive_next, {anno=[],arg}). - -%% State record for kernel translator. --record(kern, {func, %Current function - vcount=0, %Variable counter - fcount=0, %Fun counter - ds=[], %Defined variables - funs=[], %Fun functions - free=[], %Free variables - ws=[], %Warnings. - extinstr=false}). %Generate extended instructions - -module(#c_module{anno=A,name=M,exports=Es,attrs=As,defs=Fs}, Options) -> - ExtInstr = not member(no_new_apply, Options), - {Kfs,St} = mapfoldl(fun function/2, #kern{extinstr=ExtInstr}, Fs), - Kes = map(fun (#c_fname{id=N,arity=Ar}) -> {N,Ar} end, Es), - Kas = map(fun (#c_def{name=#c_atom{val=N},val=V}) -> - {N,core_lib:literal_value(V)} end, As), - {ok,#k_mdef{anno=A,name=M#c_atom.val,exports=Kes,attributes=Kas, - body=Kfs ++ St#kern.funs},St#kern.ws}. - -function(#c_def{anno=Af,name=#c_fname{id=F,arity=Arity},val=Body}, St0) -> - %%ok = io:fwrite("kern: ~p~n", [{F,Arity}]), - St1 = St0#kern{func={F,Arity},vcount=0,fcount=0,ds=sets:new()}, - {#ifun{anno=Ab,vars=Kvs,body=B0},[],St2} = expr(Body, new_sub(), St1), - {B1,_,St3} = ubody(B0, return, St2), - %%B1 = B0, St3 = St2, %Null second pass - {#k_fdef{anno=#k{us=[],ns=[],a=Af ++ Ab}, - func=F,arity=Arity,vars=Kvs,body=B1},St3}. - -%% body(Cexpr, Sub, State) -> {Kexpr,[PreKepxr],State}. -%% Do the main sequence of a body.

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. - --module(v3_life). - --export([module/2]). - --export([vdb_find/2]). - --import(lists, [map/2,foldl/3]). --import(ordsets, [add_element/2,intersection/2,union/2,union/1]). - --include("v3_kernel.hrl"). --include("v3_life.hrl"). - -%% These are not defined in v3_kernel.hrl. -get_kanno(Kthing) -> element(2, Kthing). -%%set_kanno(Kthing, Anno) -> setelement(2, Kthing, Anno). - -module(#k_mdef{name=M,exports=Es,attributes=As,body=Fs0}, Opts) -> - put(?MODULE, Opts), - Fs1 = map(fun function/1, Fs0), - erase(?MODULE), - {ok,{M,Es,As,Fs1}}. - -%% function(Kfunc) -> Func. - -function(#k_fdef{func=F,arity=Ar,vars=Vs,body=Kb}) -> - %%ok = io:fwrite("life ~w: ~p~n", [?LINE,{F,Ar}]), - As = var_list(Vs), - Vdb0 = foldl(fun ({var,N}, Vdb) -> new_var(N, 0, Vdb) end, [], As), - %% Force a top-level match! - B0 = case Kb of - #k_match{} -> Kb; - _ -> - Ka = get_kanno(Kb), - #k_match{anno=#k{us=Ka#k.us,ns=[],a=Ka#k.a}, - vars=Vs,body=Kb,ret=[]} - end, - {B1,_,Vdb1} = body(B0, 1, Vdb0), - {function,F,Ar,As,B1,Vdb1}. - -%% body(Kbody, I, Vdb) -> {[Expr],MaxI,Vdb}. -%% Handle a body, need special cases for transforming match_fails. -%% We KNOW that they only occur last in a body. - -body(#k_seq{arg=#k_put{anno=Pa,arg=Arg,ret=[R]}, - body=#k_enter{anno=Ea,op=#k_internal{name=match_fail,arity=1}, - args=[R]}}, - I, Vdb0) -> - Vdb1 = use_vars(Pa#k.us, I, Vdb0), %All used here - {[match_fail(Arg, I, Pa#k.a ++ Ea#k.a)],I,Vdb1}; -body(#k_enter{anno=Ea,op=#k_internal{name=match_fail,arity=1},args=[Arg]}, - I, Vdb0) -> - Vdb1 = use_vars(Ea#k.us, I, Vdb0), - {[match_fail(Arg, I, Ea#k.a)],I,Vdb1}; -body(#k_seq{arg=Ke,body=Kb}, I, Vdb0) -> - %%ok = io:fwrite("life ~w:~p~n", [?LINE,{Ke,I,Vdb0}]), - A = get_kanno(Ke), - Vdb1 = use_vars(A#k.us, I, new_vars(A#k.ns, I, Vdb0)), - {Es,MaxI,Vdb2} = body(Kb, I+1, Vdb1), - E = expr(Ke, I, Vdb2), - {[E|Es],MaxI,Vdb2}; -body(Ke, I, Vdb0) -> - %%ok = io:fwrite("life ~w:~p~n", [?LINE,{Ke,I,Vdb0}]), - A = get_kanno(Ke), - Vdb1 = use_vars(A#k.us, I, new_vars(A#k.ns, I, Vdb0)), - E = expr(Ke, I, Vdb1), - {[E],I,Vdb1}. - -%% guard(Kguard, I, Vdb) -> Guard. - -guard(#k_try{anno=A,arg=Ts,vars=[#k_var{name=X}],body=#k_var{name=X}, - handler=#k_atom{val=false},ret=Rs}, I, Vdb) -> - %% Lock variables that are alive before try and used afterwards. - %% Don't lock variables that are only used inside the try expression. - Pdb0 = vdb_sub(I, I+1, Vdb), - {T,MaxI,Pdb1} = guard_body(Ts, I+1, Pdb0), - Pdb2 = use_vars(A#k.ns, MaxI+1, Pdb1), %Save "return" values - #l{ke={protected,T,var_list(Rs)},i=I,a=A#k.a,vdb=Pdb2}; -guard(#k_seq{}=G, I, Vdb0) -> - {Es,_,Vdb1} = guard_body(G, I, Vdb0), - #l{ke={block,Es},i=I,vdb=Vdb1,a=[]}; -guard(G, I, Vdb) -> guard_expr(G, I, Vdb). - -%% guard_body(Kbody, I, Vdb) -> {[Expr],MaxI,Vdb}. - -guard_body(#k_seq{arg=Ke,body=Kb}, I, Vdb0) -> - A = get_kanno(Ke), - Vdb1 = use_vars(A#k.us, I, new_vars(A#k.ns, I, Vdb0)), - {Es,MaxI,Vdb2} = guard_body(Kb, I+1, Vdb1), - E = guard_expr(Ke, I, Vdb2), - {[E|Es],MaxI,Vdb2}; -guard_body(Ke, I, Vdb0) -> - A = get_kanno(Ke), - Vdb1 = use_vars(A#k.us, I, new_vars(A#k.ns, I, Vdb0)), - E = guard_expr(Ke, I, Vdb1), - {[E],I,Vdb1}. - -%% guard_expr(Call, I, Vdb) -> Expr - -guard_expr(#k_test{anno=A,op=Op,args=As}, I, _Vdb) -> - #l{ke={test,test_op(Op),atomic_list(As)},i=I,a=A#k.a}; -guard_expr(#k_bif{anno=A,op=Op,args=As,ret=Rs}, I, _Vdb) -> - #l{ke={bif,bif_op(Op),atomic_list(As),var_list(Rs)},i=I,a=A#k.a}; -guard_expr(#k_put{anno=A,arg=Arg,ret=Rs}, I, _Vdb) -> - #l{ke={set,var_list(Rs),literal(Arg)},i=I,a=A#k.a}; -guard_expr(#k_match{anno=A,body=Kb,ret=Rs}, I, Vdb) -> - %% Experimental support for andalso/orelse in guards. - %% Work out imported variables which need to be locked. - Mdb = vdb_sub(I, I+1, Vdb), - M = match(Kb, A#k.us, I+1, Mdb), - #l{ke={match,M,var_list(Rs)},i=I,vdb=use_vars(A#k.us, I+1, Mdb),a=A#k.a}; -guard_expr(G, I, Vdb) -> guard(G, I, Vdb). - -%% expr(Kexpr, I, Vdb) -> Expr. - -expr(#k_call{anno=A,op=Op,args=As,ret=Rs}, I, _Vdb) -> - #l{ke={call,call_op(Op),atomic_list(As),var_list(Rs)},i=I,a=A#k.a}; -expr(#k_enter{anno=A,op=Op,args=As}, I, _Vdb) -> - #l{ke={enter,call_op(Op),atomic_list(As)},i=I,a=A#k.a}; -expr(#k_bif{anno=A,op=Op,args=As,ret=Rs}, I, _Vdb) -> - Bif = k_bif(A, Op, As, Rs), - #l{ke=Bif,i=I,a=A#k.a}; -expr(#k_match{anno=A,body=Kb,ret=Rs}, I, Vdb) -> - %% Work out imported variables which need to be locked. - Mdb = vdb_sub(I, I+1, Vdb), - M = match(Kb, A#k.us, I+1, Mdb), - #l{ke={match,M,var_list(Rs)},i=I,vdb=use_vars(A#k.us, I+1, Mdb),a=A#k.a}; -expr(#k_try{anno=A,arg=Ka,vars=Vs,body=Kb,evars=Evs,handler=Kh,ret=Rs}, I, Vdb) -> - %% Lock variables that are alive before the catch and used afterwards. - %% Don't lock variables that are only used inside the try. - Tdb0 = vdb_sub(I, I+1, Vdb), - %% This is the tricky bit.

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.

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.

+ ASN1 Release Notes (Old) + Kenneth Lundin + Kenneth Lundin + + Kenneth Lundin + 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. + +

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.

The dump_log is done at startup and +%% at intervals controlled by the user. +%% +%% 2 The mnesia_down log +%% mnesia_tm appends to the log (via mnesia_log) when it +%% realizes that mnesia goes up or down on another node. +%% mnesia_init reads the log (via mnesia_log) at startup. +%% +%% 3 The backup log +%% mnesia_schema produces one tiny log when the schema is +%% initially created. mnesia_schema also reads the log +%% when the user wants tables (possibly incl the schema) +%% to be restored. mnesia_log appends to the log when the +%% user wants to produce a real backup. +%% +%% The actual access to the backup media is performed via the +%% mnesia_backup module for both read and write. mnesia_backup +%% uses the disk_log (*), BUT the user may write an own module +%% with the same interface as mnesia_backup and configure +%% Mnesia so the alternate module performs the actual accesses +%% to the backup media. This means that the user may put the +%% backup on medias that Mnesia does not know about possibly on +%% hosts where Erlang is not running. +%% +%% All these logs have to some extent a common structure. +%% They are all using the disk_log module (*) for the basic +%% file structure. The disk_log has a repair feature that +%% can be used to skip erroneous log records if one comes to +%% the conclusion that it is more important to reuse some +%% of the log records than the risque of obtaining inconsistent +%% data. If the data becomes inconsistent it is solely up to the +%% application to make it consistent again. The automatic +%% reparation of the disk_log is very powerful, but use it +%% with extreme care. +%% +%% First in all Mnesia's log file is a mnesia log header. +%% It contains a list with a log_header record as single +%% element. The structure of the log_header may never be +%% changed since it may be written to very old backup files. +%% By holding this record definition stable we can be +%% able to comprahend backups from timepoint 0. It also +%% allows us to use the backup format as an interchange +%% format between Mnesia releases. +%% +%% An op-list is a list of tuples with arity 3. Each tuple +%% has this structure: {Oid, Recs, Op} where Oid is the tuple +%% {Tab, Key}, Recs is a (possibly empty) list of records and +%% Op is an atom. +%% +%% The log file structure for the transaction log is as follows. +%% +%% After the mnesia log section follows an extended record section +%% containing op-lists. There are several values that Op may +%% have, such as write, delete, update_counter, delete_object, +%% and replace. There is no special end of section marker. +%% +%% +-----------------+ +%% | mnesia log head | +%% +-----------------+ +%% | extended record | +%% | section | +%% +-----------------+ +%% +%% The log file structure for the mnesia_down log is as follows. +%% +%% After the mnesia log section follows a mnesia_down section +%% containg lists with yoyo records as single element. +%% +%% +-----------------+ +%% | mnesia log head | +%% +-----------------+ +%% | mnesia_down | +%% | section | +%% +-----------------+ +%% +%% The log file structure for the backup log is as follows. +%% +%% After the mnesia log section follows a schema section +%% containing record lists.

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. - -

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.

The dump_log is done at startup and -%% at intervals controlled by the user. -%% -%% 2 The mnesia_down log -%% mnesia_tm appends to the log (via mnesia_log) when it -%% realizes that mnesia goes up or down on another node. -%% mnesia_init reads the log (via mnesia_log) at startup. -%% -%% 3 The backup log -%% mnesia_schema produces one tiny log when the schema is -%% initially created. mnesia_schema also reads the log -%% when the user wants tables (possibly incl the schema) -%% to be restored. mnesia_log appends to the log when the -%% user wants to produce a real backup. -%% -%% The actual access to the backup media is performed via the -%% mnesia_backup module for both read and write. mnesia_backup -%% uses the disk_log (*), BUT the user may write an own module -%% with the same interface as mnesia_backup and configure -%% Mnesia so the alternate module performs the actual accesses -%% to the backup media. This means that the user may put the -%% backup on medias that Mnesia does not know about possibly on -%% hosts where Erlang is not running. -%% -%% All these logs have to some extent a common structure. -%% They are all using the disk_log module (*) for the basic -%% file structure. The disk_log has a repair feature that -%% can be used to skip erroneous log records if one comes to -%% the conclusion that it is more important to reuse some -%% of the log records than the risque of obtaining inconsistent -%% data. If the data becomes inconsistent it is solely up to the -%% application to make it consistent again. The automatic -%% reparation of the disk_log is very powerful, but use it -%% with extreme care. -%% -%% First in all Mnesia's log file is a mnesia log header. -%% It contains a list with a log_header record as single -%% element. The structure of the log_header may never be -%% changed since it may be written to very old backup files. -%% By holding this record definition stable we can be -%% able to comprahend backups from timepoint 0. It also -%% allows us to use the backup format as an interchange -%% format between Mnesia releases. -%% -%% An op-list is a list of tuples with arity 3. Each tuple -%% has this structure: {Oid, Recs, Op} where Oid is the tuple -%% {Tab, Key}, Recs is a (possibly empty) list of records and -%% Op is an atom. -%% -%% The log file structure for the transaction log is as follows. -%% -%% After the mnesia log section follows an extended record section -%% containing op-lists. There are several values that Op may -%% have, such as write, delete, update_counter, delete_object, -%% and replace. There is no special end of section marker. -%% -%% +-----------------+ -%% | mnesia log head | -%% +-----------------+ -%% | extended record | -%% | section | -%% +-----------------+ -%% -%% The log file structure for the mnesia_down log is as follows. -%% -%% After the mnesia log section follows a mnesia_down section -%% containg lists with yoyo records as single element. -%% -%% +-----------------+ -%% | mnesia log head | -%% +-----------------+ -%% | mnesia_down | -%% | section | -%% +-----------------+ -%% -%% The log file structure for the backup log is as follows. -%% -%% After the mnesia log section follows a schema section -%% containing record lists. A record list is a list of tuples -%% where {schema, Tab} is interpreted as a delete_table(Tab) and -%% {schema, Tab, CreateList} are interpreted as create_table. -%% -%% The record section also contains record lists. In this section -%% {Tab, Key} is interpreted as delete({Tab, Key}) and other tuples -%% as write(Tuple).
