Own Id: OTP-17865 Aux Id: GH-5571
Debugger 5.2
Improvements and New Features

Own Id: OTP-17574
Debugger 5.1
Improvements and New Features
Extended error information for failing BIF calls as proposed in EEP 54 has been implemented.
When a BIF call from the Erlang shell fails, more information about which argument or arguments that were in error will be printed. The same extended error information will by
proc_lib
,common_test
, andqlc
when BIF calls fail.For applications that wish to provide the same extended error information, there are new functions
erl_error:format_exception/3
anderl_error:format_exception/4
.There is a new
error/3
BIF that allows applications or libraries to provide extended error information in the same way for their own exceptions.Own Id: OTP-16686
Debugger 5.0
Improvements and New Features
EEP-52 has been implemented.
In binary matching, the size of the segment to be matched is now allowed to be a guard expression, and similarly in map matching the keys can now be guard expressions. See the Erlang Reference Manual and Programming Examples for more details.
Language compilers or code generators that generate Core Erlang code may need to be updated to be compatible with the compiler in OTP 23. For more details, see the section Backwards Compatibility in EEP 52.
Own Id: OTP-14708
The deprecated
erlang:get_stacktrace/0
BIF now returns an empty list instead of a stacktrace. To retrieve the stacktrace, use the extended try/catch syntax that was introduced in OTP 21.erlang:get_stacktrace/0
is scheduled for removal in OTP 24.* POTENTIAL INCOMPATIBILITY *
Own Id: OTP-16484

Reported-by: José Valim
Own Id: OTP-11922
Debugger 4.0
Fixed Bugs and Malfunctions
The debugger now correctly evaluates code such as '
X = true andalso X
'. (Thanks to Anthony Ramine.)Own Id: OTP-11553
A few subtle bugs in the evaluation of code in the debugger has been corrected. (Thanks to Anthony Ramine.)
Own Id: OTP-11676
Application upgrade (appup) files are corrected for the following applications:
asn1, common_test, compiler, crypto, debugger, dialyzer, edoc, eldap, erl_docgen, et, eunit, gs, hipe, inets, observer, odbc, os_mon, otp_mibs, parsetools, percept, public_key, reltool, runtime_tools, ssh, syntax_tools, test_server, tools, typer, webtool, wx, xmerl
A new test utility for testing appup files is added to test_server. This is now used by most applications in OTP.
(Thanks to Tobias Schlager)
Own Id: OTP-11744
Improvements and New Features
Removed gs based applications and gs based backends. The
observer
application replaces the removed applications.* POTENTIAL INCOMPATIBILITY *
Own Id: OTP-10915
Support Maps syntax in debugger (Thanks to Anthony Ramine).
Own Id: OTP-11673
Debugger 3.2.12
Improvements and New Features
Fix matching of floating point middle-endian machines. Thanks to Johannes Weissl.
Own Id: OTP-11201
Debugger 3.2.11
Improvements and New Features
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.
Own Id: OTP-10899
Erlang source files with non-ASCII characters are now encoded in UTF-8 (instead of latin1).
Own Id: OTP-11041 Aux Id: OTP-10907
Debugger 3.2.10
Improvements and New Features
The +pc flag to erl can be used to set the range of characters considered printable. This affects how the shell and io:format("~tp",...) functionality does heuristic string detection. More can be read in STDLIB users guide.
Own Id: OTP-10884
Debugger 3.2.9
Fixed Bugs and Malfunctions
Fix Debugger settings dialog due to changed behavior in wxFileDialog (Thanks to Håkan Mattsson)
Own Id: OTP-10621
Improvements and New Features
Support for Unicode has been implemented.
Own Id: OTP-10302
Where necessary a comment stating encoding has been added to Erlang files. The comment is meant to be removed in Erlang/OTP R17B when UTF-8 becomes the default encoding.
Own Id: OTP-10630
Integer lists and utf-8 binaries in variables are now displayed as strings.
Own Id: OTP-10679
Debugger 3.2.8
Fixed Bugs and Malfunctions
Fixed disappearing breakpoints bug, reported by Ricardo Catalinas Jiménez.
Own Id: OTP-9950
Debugger 3.2.7
Fixed Bugs and Malfunctions
Fix "OK" spelling in debugger messages and variables
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.(Thanks to Ricardo Catalinas Jiménez)
Own Id: OTP-9699
Improvements and New Features
Variables are now now allowed in '
fun M:F/A
' as suggested by Richard O'Keefe in EEP-23.The representation of '
fun M:F/A
' in the abstract format has been changed in an incompatible way. Tools that directly read or manipulate the abstract format (such as parse transforms) may need to be updated. The compiler can handle both the new and the old format (i.e. extracting the abstract format from a pre-R15 BEAM file and compiling it using compile:forms/1,2 will work). Thesyntax_tools
application can also handle both formats.* POTENTIAL INCOMPATIBILITY *
Own Id: OTP-9643
Debugger 3.2.6

Own Id: OTP-8201
Debugger 3.2
Improvements and New Features
Added a new gui, start with debugger:start(gs) for old gui.
Own Id: OTP-7366

is_constant/1
has been removed.* INCOMPATIBILITY with R12B *
Own Id: OTP-7673
Debugger 3.1.1.4
Improvements and New Features
There is now experimental support for loading of code from archive files. See the documentation of
code
,init
,erl_prim_loader
andescript
for more info.The error handling of
escripts
has been improved.An
escript
may now set explicit arguments to the emulator, such as-smp enabled
.An
escript
may now contain a precompiled beam file.An
escript
may now contain an archive file containing one or more applications (experimental).The internal module
code_aux

Own Id: OTP-6725
Debugger 3.1.1
Fixed Bugs and Malfunctions
Removed some dead code from
dbg_ieval
.Own Id: OTP-6552
Debugger 3.1
Fixed Bugs and Malfunctions
The interpreter could not handle the case where an expression that should evaluate to a fun referred to uninterpreted code.
Own Id: OTP-6061 Aux Id: seq10295
Timeout for
gen_server
calls within Debugger is now set toinfinity
.Own Id: OTP-6103
Improvements and New Features
Notification windows are now centered over a parent window.
Own Id: OTP-6011 Aux Id: OTP-5987
When interpreting a module, it is now checked that the module does not belong to the Kernel, STDLIB, GS or Debugger application, as interpreting a module used by the debugger/interpreter itself will lead to a deadlock or emulator crash.
Also
int:interpretable(Mod)
has been extended to return{error,{app,App}}
ifMod
belongs to one of the above applications.Own Id: OTP-6020
andalso
/orelse
is now supported.Own Id: OTP-6021 Aux Id: OTP-5894

Own Id: OTP-5837
Improvements and New Features
A number of smaller improvements to the GUI:
- Multiple choices now possible in Function Break Dialog Window.
- Right-clicking the Module entry in a Break Dialog Window will open a popup menu from which the appropriate (interpreted) module can be selected.
- Auto Attach options can now be changed using the buttons in the left part of the Monitor Window, not only by the corresponding menu buttons.
- Buttons for enabling and disabling all breakpoints have been added.
- View Module Window keyboard shortcuts corrected.
Own Id: OTP-4284
Debugger 3.0
Improvements and New Features
Debugger can now handle
try-catch
. This meant large parts of the interpreter had to be rewritten. Also, some small changes to the GUI have been made.Own Id: OTP-5730
Debugger 2.3.3
Improvements and New Features
It is now possible to encrypt the debug information in Beam files, to help keep the source code secret. See the documentation for compile on how to provide the key for encrypting, and the documentation for beam_lib on how to provide the key for decryption so that tools such as the Debugger, Xref, or Cover can be used.
The
beam_lib:chunks/2
functions now accepts an additional chunk type 'compile_info
' to retrieve the compilation information directly as a term. (Thanks to Tobias Lindahl.)Own Id: OTP-5460 Aux Id: seq9787
Debugger 2.3.2
Fixed Bugs and Malfunctions
The graphic applications now search for HTML documentation in the correct place.
