EiffelStudio 6.1.x Releases

6.1.x

Placeholder for new stuff since last intermediate release.

New features

• studio: Windows Tool now has a New Window button.
• studio: Error list tool now has an option to expand the errors automatically to show the verbose information.
• compiler: Non-conforming inheritance

Feature removed

Bug fixes

• studio: Fixed column resizing issue on Error List Tool.
• debugger: Added support for type creation expression in debugger's evaluator (i.e {FOO} will be evaluated to an instance of TYPE [FOO])
• debugger: Fixed bug#13453: Force debug mode disables Debug | Tools menu on start
• runtime: Prevented a dead lock after an exception occurs while retrieving an object in a multithreaded environment (fixed eweasel test#store012).
• compiler: Fixed various multi-error issues where compiler was crashing instead of reporting an error.
• compiler: Fixed non-recompilation of a class whose ancestor had an error during degree 4 (fixed eweasel test#multierr007).
• debugger: new dialog to customize the objects tool's layout
• studio: fixed bug#13444: Feature tool is not shown when selecting an entry in the call stack
• debugger: Fixed bug#13411: feature tool process 2 treatments instead of 1 when stone is dropped (and similiar bug#12903)
• debugger: Fixed bug#13443: Current object always expand
• debugger: Fixed bug#13453: Force debug mode disables Debug | Tools menu on start
• debugger: added support for type creation on expression evaluator (ie: "{FOO}" will return an instance of TYPE [FOO])

User changes

Developer changes

• studio: Switch to using new dynamic tool activation model.
• Started reorganizing tools and foundation APIs

6.1.7.0574 (October 15th)

New features

• More than one error is reported at degree 3: all classes are compiled at degree 3 and all errors are displayed at the end.
• New replay execution mechanism in debugger: record an execution to replay it. This is useful when debugging a complex system where you just encountered a bug. At this point, play back the execution to find where the problem really occurred without restarting your debug session.
• New debuggee object storage: provide the ability to *independent_*store a debuggee object, and to reload it. (Available through a tool bar button in the watch tools)

Bug fixes

• compiler: Fixed a potential infinite loop during degree 5 when a class has a change that requires all its syntactical suplier to be recompiled (e.g. adding/removing a formal generic paramter)
• studio: Fixed errors and warnings tool counter corruption issue when opening multiple windows.
• studio: Fixed profiler which would give random results when analyzing the output of a finalized execution.
• vision2: Fixed issue with the `wel_hook.dll' not working anymore on 32-bit platforms.
• debugger: Fixed bug#13373: TUPLE.object_comparison not shown in the debugger

6.1.7.0472 (October 1st)

New features

• runtime: Implemented on Windows the GC_INFO features: cpu_* and sys_*.
• studio: Completion list now repeatedly shows after pressing '.' when the completion list is active.
• studio: Completion list no longer shows obsolete items by default. Added completion list/preference options to enable/disable this.
• studio: Made use of new confirmation dialogs.
• studio: Added filter, and navigation aspects to the errors and warnings tool.
• studio: Added a "-low" option to finish_freezing to run finish_freezing in a lower execution priority mode. The Eiffel compiler now launches finish_freezing in this mode by default.
• studio: Compiler report more than one error during degree 5.
• compiler: Sped up `full_class_checking' by a significant factor during degree 3 (went from 180s down to 80s).
• compiler: Added new option `check_for_void_target' to detect call on Void targets in finalized mode. It can cause a slight performance degradation. It is now the default.

Feature removed

Bug fixes

• studio: Fixed completion on (create {XXX}) expressions.
• debugger: Fixed issue bug#13388: Duplicating a debugger profile which is selected results in 2 selected profiles
• debugger: Fixed bug#13367: Conditional breakpoint with condition "not Result" crashes estudio
• debugger: Fixed bug#13366: Please support Home and End keys in the Objects tool
• studio: Fixed bug#13406: Positions pick and drop and external editors
• compiler: Fixed test#exec280 where default_create was never called when it had an empty body. This would cause a problem if the creation's type is redefined in descendants.
• runtime: Enabled `time accounting' on Windows to find how much time is spent in GC.

User changes

Developer changes

• studio: Integrated new based implementation for all future dialogs and dialog prompts.
• compiler: Continued improvements on new single line error and error context. (Please send all bug reports about unclear errors, only for the most recent release!)

6.1.6.9962 (August 14th)

New features

• studio: All new Errors and Warning tool to replace Errors tool and Warnings tool.
• studio: Tool tips now use variable width fonts instead of the editor mono-spaced fonts.
• studio: C/C++ compilation failures now show up in as an error in the Errors and Warnings tool.

Feature removed

Bug fixes

• vision2: Fixed a USER object leak on Windows in the Vision2 and WEL library for pixmaps and accelerators. This was causing EiffelStudio to not work properly after creating/closing many windows or when changing the layout of EiffelStudio many times.
• installer: Fixed installer on Windows which would update the 6.0 registry keys.
• mingw: Fixed some incorrect C compiler configuration files.

Developer changes

• studio: Added Griffin service-based framework for EiffelStudio

6.1.6.9765 (August 2nd)

New features

• Added support for the MinGW C compiler on Windows.
• New default layout of EiffelStudio.

Roadmap to ISO/ECMA Eiffel

This important page describes the steps, accomplished and planned, towards completing the integration into the EiffelStudio compiler of the whole set of mechanisms specified by the ISO/ECMA international standard for the Eiffel language.
