User changes

Developer changes

6.6.8.2214 (February 1st 2010)

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.
• base: Added support for nan, negative_infinity, positive_infinity and their `is_xxx' corresponding queries.
• base: Allowed {ARRAY}.force to be used with arrays of attached types when index is either `lower - 1' or `upper + 1'. This let you progressively fill an empty array from 1 to the expected count.

Feature removed

Bug fixes

• compiler: Fixed eweasel test#agent001 and test#agent013 by preventing wrong optimization when call to `{ROUTINE}.call' or `{FUNCTION}.item' are subject to dynamic binding.
• compiler: Fixed bug#16593 where finalizing twice in the same sessions with many changes in the system could cause the compiler to crash during degree -3.
• 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.
• runtime: Fixed eweasel test#store029 where retrieving a storable made by 6.3 or older could fail with a mismatch error when there is actually no mismatch.
• 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.
• base: Fixed ARRAY2 so that it can be used in void-safe mode too. Improved ARRAY2 resizing efficiency.

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.
• compiler: Now the compiler will report usage of is keyword as obsolete in transitional mode and will reject it in standard mode.
