EiffelStudio 6.6.x Releases

6.6.x

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
   Compound
end

Improvements

• 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.

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
• 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.

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.
