EiffelStudio 6.6.x Releases


Placeholder for new stuff since last intermediate release.

New features

  • compiler: Supported new variant of a check instruction that is not subject for assertion monitoring settings (in other words the check cannot be turned off) and can be used to introduce a new void safe scope of a read-only or object test local:
check Assertion then


  • runtime: Redone some of the multithreading internals of the Eiffel runtime to make it easier to add platforms and to ensure the same behavior on various platforms.
  • runtime: On Windows, the MUTEX class is now internally using a CRITICAL_SECTION object which is much more efficient especially with multiprocessors.
  • base: Added support for nan, negative_infinity, positive_infinity and their `is_xxx' corresponding queries.

Feature removed

Bug fixes

  • studio: Fixed editor refresh issue when saving modifications in the Contract Tool.
  • studio: Fixed catcalls when building the Contract Tool.
  • studio: Fixed bug#14857 Store the external commands in ISE User files
  • studio: Fixed bug#16410 Error List window comes up blank on error if auto-hidden when estudio started
  • debugger: Fixed a hang in EiffelStudio when inspecting a different threads than the current stopped one on platforms where thread identifiers are larger than 32-bit (e.g. Linux)
  • runtime: Made sure to use recursive mutexes on all our platforms.
  • net: Fixed tftp_server_console sample so that it uses a multithreaded precompilation of EiffelBase and fixed a precondition violation when receiving a GET command.
  • net: Fixed precondition violation in {ARRAY}.force when compiling EiffelNet in void-safe mode.
  • net: Changed internal of MEDIUM_POLLER to use HASH_TABLE, as a consequence the queries `read_command_list', `write_command_list' and `exception_command_list' are now obsolete and should not be used.

User changes

  • thread: Made the THREAD class thread-safe which prevents using the same object to launch a new thread. Now there is a precondition `is_launchable' and a status report `is_last_launch_successful' to help finding out if a thread was really launched.
  • base: Changed the display of REAL/DOUBLE fields to show REAL_32 or REAL_64.
  • base: Changed the display of NaN/-Infinity/Infinity for real numbers so that it is the same on all our supported platforms.
