* bjorn/fix-encoding/OTP-11041: Encode Erlang source files with non-ascii characters in UTF-8
2013-04-17Encode Erlang source files with non-ascii characters in UTF-8Björn Gustavsson
To ensure that 'master' compiles when we merge 'maint' to it, regardless of which encoding is default in 'master', all source files with non-ascii characters *must* have the encoding specified.

2013-03-07[debugger] Add an option 'Strings'Hans Bolinder
A new checkbox has been added. When it is checked, the range set by the 'erl' flag '+pc' is used for determining when to print lists of integers as strings. When it is unchecked, integer lists are never printed as strings. A minor incompatibility: settings saved by Erlang R16B01 or later cannot be read by Erlang R16B or earlier.

2013-01-15Implement ./otp_build configure --enable-silent-rulesAnthony Ramine
With silent rules, the output of make is less verbose and compilation warnings are easier to spot. Silent rules are disabled by default and can be disabled or enabled at will by make V=0 and make V=1.

2013-01-11debugger: View terms as unicode-stringsDan Gudmundsson
Changed the displayed variables to be printed with ~tp to show default all lists and utf-8 binaries as unicode strings. If the user want to see the content without unicode strings he can click on them to see the content as integers, if not it only contains latin1 because ~p converts that. There is currently no way to display it as lists with indentation, so I choose to keep it as it was.

2011-11-09Fix "OK" spelling in debugger messages and variablesRicardo Catalinas Jiménez
Simple code refactor in the debugger: renames all the occurrences of "Ok" to "OK" in the code, variable names and strings. This improves the consistency of the code and follows the GTK UI where "OK" is always used.
2011-11-09Fix debugger message with wxRicardo Catalinas Jiménez
Add missing spaces when using wx UI. The gs UI didn't need them. Change the exclamation of the message by a dot, more formal style for a UI message.
2011-11-07EEP-23: Allow variables in fun M:F/ABjörn Gustavsson
Currently, the external fun syntax "fun M:F/A" only supports literals. That is, "fun lists:reverse/1" is allowed but not "fun M:F/A". In many real-life situations, some or all of M, F, A are not known until run-time, and one is forced to either use the undocumented erlang:make_fun/3 BIF or to use a "tuple fun" (which is deprecated). EEP-23 suggests that the parser (erl_parse) should immediately transform "fun M:F/A" to "erlang:make_fun(M, F, A)". We have not followed that approach in this implementation, because we want the abstract code to mirror the source code as closely as possible, and we also consider erlang:make_fun/3 to be an implementation detail that we might want to remove in the future. Instead, we will change the abstract format for "fun M:F/A" (in a way that is not backwards compatible), and while we are at it, we will move the translation from "fun M:F/A" to "erlang:make_fun(M, F, A)" from sys_pre_expand down to the v3_core pass. We will also update the debugger and xref to use the new format. We did consider making the abstract format backward compatible if no variables were used in the fun, but decided against it. Keeping it backward compatible would mean that there would be different abstract formats for the no-variable and variable case, and tools would have to handle both formats, probably forever.

2011-08-18debugger: By default, only save non-tail-recursive callsBjörn Gustavsson
By default, the debugger use to save all calls on its simulated stack. That could facilitate finding errors, but it could also mean that the Debugger could become very slow while executing tail-recursive code.
2011-08-18debugger: Include line numbers in exceptionsBjörn Gustavsson
2011-08-16emulator: Add a fourth element in exception stacktracesBjörn Gustavsson
This commit is a preparation for introducing location information (filename/line number) in stacktraces in exceptions. Currently a stack trace looks like: [{Mod1,Function1,Arity1}, . . . {ModN,FunctionN,ArityN}] Add a forth element to each tuple that can be used indication the filename and line number of the source file: [{Mod1,Function1,Arity1,Location1}, . . . {ModN,FunctionN,ArityN,LocationN}] In this commit, the fourth element will just be an empty list, and we will change all code that look at or manipulate stacktraces.
2011-08-16Remove support for very old BEAM filesBjörn Gustavsson
Since the run-time system cannot load those BEAM files, it was not possible to debug them anyway.
2011-08-16Don't include tail-recursive calls in stacktracesBjörn Gustavsson
The stacktrace in debugger-generated exceptions should be as similar to stacktraces in BEAM-generated exceptions as possible.
2011-08-16Fix the no_tail optionBjörn Gustavsson
The 'no_tail' option was broken and would work almost as the 'all' option, because it would use #ieval.top (formerly known as #ieval.last_call) as the basis for its decision to push or not. Fix it by including a boolean in each call/apply instruction indicating whether the call is tail-recursive and pass that boolean to the dbg_istk:push() function.
2011-08-16dbg_ieval: Properly handle exceptions when binary construction failsBjörn Gustavsson
An exception from eval_bits:expr_grp/5 (for constructing binaries) was not caught and handled by exception/4; thus exit_info and and stacktrace for the process was not set.
2011-08-16Fix binary matching in the debuggerBjörn Gustavsson
'eval_bits' is a common utility module used for evaluting binary construction and matching. 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.
2011-08-16Delay saving of the stack in exit_info when an exception occursBjörn Gustavsson
When an exception occurs, the entire stack will be converted to the external term format and kept in the exit_info variable in the process dictionary. But the exit_info variable will only be needed if the exception causes the process to terminate (not if it is caught). Delay the conversion of the stack to external format. That can save significant amounts of time (e.g. in bs_construct:mem_leak/1).
2011-08-16Fix handling of guard BIFs in list and binary comprehensionsBjörn Gustavsson
In a list comprehension, a failing call to a guard BIF means false (rather than an exception).
2011-08-16Handle terms in the top-level of guards properlyBjörn Gustavsson
Expressions in guards such as: f() when [1,2,3] -> ok. would cause the debugger to crash when attempting to interpret the module containing the expressions. Other kind of constants such as: f() when 42 -> ok. were converted to an invalid internal format ({integer,Line,42} instead of {value,Line,42}), but that happened to work because because anything not equal to 'true' (even a crash) was interpreted as 'false'. Make sure to handle all possible expressions and convert them directly to {value,Line,false}. Remove the special handling of the atom 'true' in and_guard/1 since it is no longer needed.
2011-08-16Make sure that erlang:raise/3 sets the emulated stacktraceBjörn Gustavsson
erlang:raise/3 was evaluated in the real process, which produced a correct stacktrace, but did not set emulated stacktrace for the process. Thus, a subsequent call to erlang:get_stacktrace/0 would retrieve the previous stacktrace for the process.
2011-08-16Make stacktraces in exceptions more similar to BEAM's stacktracesBjörn Gustavsson
When an exception was generated from interpreted code, the stacktrace would not look exactly like BEAM's stacktraces. There would generally be fewer entries (never more than three), and the top entry would always have MFAs with the actual arguments (rather than the arity). 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.
2011-08-16Don't build stacktrace until erlang:get_stacktrace() is calledBjörn Gustavsson
Currently, dbg_istk:exception_stacktrace/2 does not do a very good job imitating BEAM's stacktrace. 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. To prepare for a future more thorough (and slower) stacktrace construction, refactor the building of the stacktrace so that it only is done when erlang:get_stacktrace/0 is called.
