EiffelStudio 7.1.x Releases

7.1.x.y (...)

New features

Improvements

• compiler: bug#17591, bug#17662 (test#pretty028) - Improved formatting of comments delimited with blank lines.
• vision2: one can now provide a hint of the size of the dropdown list of the combobox. The hint is currently only effective on Windows.
• vision2: Improved the default size of the dropdown list of a combobox so that all the text can be visible.
• compiler: test#valid275 - Reduced the number of cases when VWEQ warning is reported, in particular by limiting it to the immediate code only.
• compiler: test#tilde002 - Optimized code generation for the equality test that involves two values of different expanded types.
• compiler: bug#15145 (test#exec296) - Supported detection and warning report with code VWAB for useless bodies of attributes that are never executed because the types of the attributes are self-initialized (expanded or detachable).
• library: test#array009 - Relaxed a precondition of {ARRAY}.force that was too restrictive for elements of an attached type.
• library, example: Removed assignment attempt from the most part of the source code because this instruction is now obsolete.
• compiler: Relaxed the rule VD88 to report void-safety mismatch between client and supplier as a warning rather than an error when complete void safety is not requested.

Feature removed

• compiler: test#vwmq001 - Disabled type qualifier in the manifest constant used to declare a constant attribute because the type is already specified in the feature header.

Bug fixes

• compiler: bug#15147 (test#term168) - Fixed compiler crash caused by inline agents with the body in the form of an attribute.
• compiler: bug#15450, bug#18098 (test#melt088) - Corrected error in melted byte code generation for constant attributes of type CHARACTER_32 that could lead to a wrong value at run-time.
• compiler: bug#17590 - Added type conversion to avoid C compiler warnings in some SCOOP macros.
• compiler: bug#17987 (test#incr421) - Applied application options to library classes during recompilation when required.
• compiler: bug#18045 (test#vwmq001) - Added detection and error report of VWMQ violation for manifest string constants with type qualifiers other STRING_8 and STRING_32.
• compiler: bug#18047 (test#valid274) - Avoided duplication of VFAC(1) error report.
• compiler: bug#18067 (test#attach096) - Reported VEVI error if an unqualified agent is created when not all the attributes are properly set.
• compiler: test#replication008 - Ensured that replication information is preserved when feature is undefined in a descendant class so that inherited assertions are generated correctly.
• compiler: test#replication009 - Avoided a crash when processing inherited preconditions of a replicated feature.
• compiler: test#exec338 - Fixed code generation for equality tests that involve different basic types resulted from formal generic parameter substitutions.
• compiler: test#scoop024 - Fixed processing of multi-dot call chain that involves separate target, so that subsequent calls are generated as separate rather than normal ones even in the case when return type is not separate.
• compiler: test#syntax045 - Fixed a bug that leaved '%R' when parsing a verbatim string with an empty first line.
• library: bug#18153 (test#string001) - Corrected the implementation of {STRING_32}.left_adjust that did not work properly when the string contained only white spaces.
• compiler: test#dotnet113 - Corrected code generation for object tests when the target type is a basic one and the expression gives a boxed value of the primitive type.

User changes

• compiler: review#7289252 (test#replication009) - Enabled system freeze for precompiled library when all classes are requested to be compiled.
• thread: made the EiffelThread library compliant with SCOOP. This required adding a creation procedure `make' to the THREAD class to initialize some internal changes to avoid a thread object from being launched in various threads. If your code inherit from THREAD, you now have to call `make' otherwise you will either get a compilation error in void-safe mode, or a call on void-target in non-void-safe mode when trying to launch a thread.
• compiler: Marked assignment attempt symbol ?= as obsolete for all syntax variants except for the obsolete one.
