If the 'no_tail' option is set for the process, there may not be an entry for level 2. * In each stack entry, the line number is the line number of the caller, not the line number for the function in the 'mfa' field as might be expected. That complicates generation of a stacktrace with line number information. Change the implementation as follows: * Keep the information for the current function (its MFA and current line number) in the #ieval{} record. Don't push it onto the stack. Only push the information when another function is called. That will ensure that the MFA and the line number is found in the same stack entry. That also has the advantage that if the 'no_tail' option is set, the stack not need to be modified for tail-recursive calls. * Make sure that there always is an entry for level two. --- lib/debugger/src/dbg_icmd.erl | 4 +-- lib/debugger/src/dbg_ieval.erl | 61 ++++++++++++++++++++---------------------- lib/debugger/src/dbg_istk.erl | 49 ++++++++++++++++++--------------- 3 files changed, 58 insertions(+), 56 deletions(-) (limited to 'lib') diff --git a/lib/debugger/src/dbg_icmd.erl b/lib/debugger/src/dbg_icmd.erl index c158aad1cf..b230efaa7a 100644 --- a/lib/debugger/src/dbg_icmd.erl +++ b/lib/debugger/src/dbg_icmd.erl @@ -345,8 +345,8 @@ handle_user_msg({get,stack_frame,From,{Dir,SP}}, _Status, _Bs,_Ieval) -> reply(From, stack_frame, dbg_istk:stack_frame(Dir, SP));

The reason is that it need to be relatively fast since a simulated stacktrace is constructed not only when an exception oocurs, but also before every call to non-interpreted code.

There are two good reasons for making the stacktraces as similar as possible: * Code that examines a stacktrace can behave differently in the interpreted and BEAM code if the stacktraces are different. * It is easier to test the debugger if test suites for other applications (such as the emulator) can be run with the debugger with as few modifications as possible. --- lib/debugger/src/dbg_ieval.erl | 24 ++++++++---- lib/debugger/src/dbg_istk.erl | 83 ++++++++++++++++++++---------------------- 2 files changed, 55 insertions(+), 52 deletions(-) (limited to 'lib') diff --git a/lib/debugger/src/dbg_ieval.erl b/lib/debugger/src/dbg_ieval.erl index fe7f9af1a9..32848a00ff 100644 --- a/lib/debugger/src/dbg_ieval.erl +++ b/lib/debugger/src/dbg_ieval.erl @@ -168,10 +168,18 @@ check_exit_msg(_Msg, _Bs, _Ieval) -> %% and then raise the exception. %%-------------------------------------------------------------------- exception(Class, Reason, Bs, Ieval) -> - exception(Class, Reason, dbg_istk:delayed_stacktrace(Ieval), - Bs, Ieval). - -exception(Class, Reason, Stacktrace, Bs, #ieval{module=M, line=Line}) -> + exception(Class, Reason, Bs, Ieval, false). + +exception(Class, Reason, Bs, Ieval, false) -> + do_exception(Class, Reason, + dbg_istk:delayed_stacktrace(no_args, Ieval), + Bs, Ieval);

The functions that do matching (match_bits/{6,7} and bin_gen/6) are supposed to treat the bindings as an abstract data type, but they assume that the bindings have the same representation as in the erl_eval module. That may cause binary matching to fail in the debugger, because the debugger represents the bindings as an unordered list of two-tuples, while the erl_eval modules uses an ordered list of two-tuple (an ordset). One way to fix the problem would be to let the debugger to use ordered lists to represent the bindings. Unfortunately, that would also change how the bindings are presented in the user interface. Currently, the variable have most been recently assigned is shown first, which is convenient. Fix the matching problem by mending the leaky abstraction in eval_bits. The matching functions needs to be passed two additional operations: one for looking up a variable in the bindings and one for adding a binding. Those operations could be passed as two more funs (in addition to the evaluation and match fun already passed), but the functions already have too many arguments. Therefore, change the meaning of the match fun, so that the first argument is the operation to perform ('match', 'binding', or 'add_binding') and second argument is a tuple with arguments for the operation. --- lib/compiler/src/v3_kernel.erl | 9 ++++-- lib/debugger/src/dbg_ieval.erl | 16 +++++++---- lib/debugger/test/bs_match_misc_SUITE.erl | 15 ++++++++-- lib/stdlib/src/erl_eval.erl | 10 +++++-- lib/stdlib/src/eval_bits.erl | 47 ++++++++++++++++--------------- 5 files changed, 62 insertions(+), 35 deletions(-) (limited to 'lib') diff --git a/lib/compiler/src/v3_kernel.erl b/lib/compiler/src/v3_kernel.erl index 3b33a08cf7..0bbedf0207 100644 --- a/lib/compiler/src/v3_kernel.erl +++ b/lib/compiler/src/v3_kernel.erl @@ -1167,9 +1167,7 @@ select_bin_int_1(_, _, _, _) -> throw(not_possible). select_assert_match_possible(Sz, Val, Fs) -> EmptyBindings = erl_eval:new_bindings(), - MatchFun = fun({integer,_,_}, NewV, Bs) when NewV =:= Val -> - {match,Bs} - end, + MatchFun = match_fun(Val), EvalFun = fun({integer,_,S}, B) -> {value,S,B} end, Expr = [{bin_element,0,{integer,0,Val},{integer,0,Sz},[{unit,1}|Fs]}], {value,Bin,EmptyBindings} = eval_bits:expr_grp(Expr, EmptyBindings, EvalFun), @@ -1184,6 +1182,11 @@ select_assert_match_possible(Sz, Val, Fs) -> throw(not_possible) end. +match_fun(Val) -> + fun(match, {{integer,_,_},NewV,Bs}) when NewV =:= Val -> + {match,Bs} + end. + select_utf8(Val0) -> try Bin = <>, diff --git a/lib/debugger/src/dbg_ieval.erl b/lib/debugger/src/dbg_ieval.erl index 9b6919074f..b0792b05f0 100644 --- a/lib/debugger/src/dbg_ieval.erl +++ b/lib/debugger/src/dbg_ieval.erl @@ -1023,7 +1023,7 @@ eval_generate(Term, _P, Bs, _CompFun, Ieval) -> exception(error, {bad_generator,Term}, Bs, Ieval). eval_b_generate(<<_/bitstring>>=Bin, P, Bs0, CompFun, Ieval) -> - Mfun = fun(L, R, Bs) -> match1(L, R, Bs, Bs0) end, + Mfun = match_fun(Bs0), Efun = fun(Exp, Bs) -> expr(Exp, Bs, #ieval{}) end, case eval_bits:bin_gen(P, Bin, erl_eval:new_bindings(), Bs0, Mfun, Efun) of {match,Rest,Bs1} -> @@ -1392,11 +1392,9 @@ match1({cons,_,H,T}, [H1|T1], Bs0, BBs) -> match1({tuple,_,Elts}, Tuple, Bs, BBs) when length(Elts) =:= tuple_size(Tuple) -> match_tuple(Elts, Tuple, 1, Bs, BBs);

This means, however, that information is saved also for tail - recursive calls. For example, repeated calls to the loop - function of an Erlang process. This may consume unnecessary - amounts of memory for debugged processes with long lifetimes and - many tail recursive calls.
