EiffelStudio 18.11.x Releases

Beta download: https://ftp.eiffel.com/pub/beta/18.11/

18.11.xx.yyyy ()

New features

  • library (wel): Added features to draw multiple lines and polygons, to fill polygons, and to enable anti-aliasing when using GDI+. Added features to set dash styles and line joins for a pen when using GDI+.
  • compiler: Used assertion expressions as assertion tags when the tags are absent to improve diagnostics of assertion violations. For example, an untagged assertion with an expression is_valid is considered as having a tag is_valid.
  • library (base): Added to HASH_TABLE a feature definite_item that always returns an existing element assuming that the key is in the table (the feature has the corresponding precondition).
  • compiler: Supported conditions based on current void safety compilation mode.

Improvements

  • library (uuid): Marked {UUID_GENERATOR}.generate_uuid as a class feature and made the code of the class SCOOP-compatible.
  • library (base): Updated CHARACTER_PROPERTIES to use Unicode 11.0.0 instead of 10.0.0.
  • compiler: Implemented direct code generation for {CHARACTER_8}.minus and {CHARACTER_32}.minus.
  • EiffelStudio (diagram): Improved scaling of client-supplier lines in a diagram tool by allowing for a minimum width of 3 pixels and proportional increase of nested lines width and arrow size to the overall line width.
  • library (base): Added a new class EMPTY_ITERATION_CURSOR that can be used to implement iteration cursors for structures without any elements.
  • library (base): Added an inheritance link from CONTAINER to ITERABLE, so that all containers can be iterated over using an across loop. Most notable additions are queues, trees and files. Potential incompatibility: a descendant of a deferred container class of the library may need to implement a feature new_cursor.
  • library (base): All features of HASH_TABLE that accepted detachable G in the arguments now take G.

Bug fixes

  • code analyzer: test#codeanalysis031 — Fixed a bug when a previously assigned variable was reported as unread (CA020) when it was both a target of a creation instruction and an argument to the corresponding creation procedure.
  • compiler: bug#19449 (test#final120, test#final126, test#runtime001) — Fixed a C code generation bug that could lead to wrong results of an equality test for references in particular cases in finalized mode when the right-hand side expression triggers GC.
  • runtime: bug#19242 (test#runtime022, test#runtime023) - Fixed a bug that could lead to object heap corruption when an argument or a local of an expanded type with (recursively nested) reference attributes is passed to a feature that triggers GC.
  • EiffelStudio: Fixed a bug that caused creation of generated files at a higher level than requested and using wrong names (such as Documentationtest.xml instead of Documentation/test.xml) when exporting to XMI.
  • EiffelStudio (diagram): Fixed a bug that might cause an exception when performing multiple switching from an item with an existing diagram to another one in a diagram tool or when switching between BON and UML views multiple times.
  • EiffelStudio (diagram): Corrected style of client-supplier links to be drawn as a double-lines in a cluster view of BON diagrams.
  • compiler: Fixed a potential bug that might cause incorrect code generation for parenthesis alias after incremental recompilation if the origin of the alias changes.
  • EiffelStudio (address bar): Allowed entering Unicode characters in the class field of the address bar (before any Unicode input was discarded).
  • EiffelStudio (context menu): bug#19469 — Fixed a bug that might result in an exception trace when trying to invoke a context menu on a class name in the project that has not been successfully compiled.
  • EiffelStudio (template manager): Fixed a bug that might cause access on void target if no template declarations are found.
  • code analyzer: test#codeanalysis005 — Avoided false positives for CA024 reported when it is possible to rewrite a regular loop as an across one.
  • compiler: Avoided assertion violation when a file cannot be signed because .NET 3.5 or earlier is not installed on the development machine.
  • compiler: Fixed a bug that could lead to using a wrong routine ID of a parenthesis alias if this routine ID changes during incremental recompilation.
  • compiler: bug#15286 (test#ccomp082), bug#17089 (test#exec332), bug#19490 (test#ccomp091) — Fixed bugs that could cause generation of invalid C code or reporting a wrong result for an object test when both source expression type and target type are expanded and incompatible.
