BDE 4.15.0 Release¶
Schedule¶
The BDE team announces that the BDE 4.15.0 production release was completed on Monday, Oct 7th, 2024.
BDE 4.15.0 Release Highlights¶
bdlb::NumericFormatterUtil::parseDouble Behavior Changes¶
bdlb::NumericFormatterUtil::parseDouble method has been updated to conform to its contract and not parse hexfloat strings, as well as to report over and underflow during parsing by returning ERANGE instead of 0 (success). When the method returns ERANGE it still sets the resulting double to +/-0 or +/-infinity so code may continue to rely on parsing underflow and overflow values floating point values (but now additional status information will be available). Note that support for hexfloat parsing was not intentional and available only on a subset of production platforms.
As a preparation for this change BSLS_REVIEW macros were introduced into the parseDouble code in 2023 that have been producing logged warnings for code inadvertently relying on underflow, overflow, or hexfloat conversions (for over a year). We have reached out to all teams producing those messages on managed machines for which alerts for logged messages were available and ensured that this change would not result in breakages.
Naming Hierarchy for Thread Enabled Object Monitoring¶
The thread-enabled objects bdlmt::ThreadPool, bdlmt::FixedThreadPool, bdlmt::EventScheduler, and bdlmt::TimerEventScheduler now implement a consistant algorithm for naming owned threads. If the supplied thread attributes has a non-empty thread name, this name is used. Otherwise, if a non-empty name was supplied to the thread-enabled object at construction, this name is used. Finally, if both of those names are empty, a type-specific default is used. Note that the thread attributes for the event schedulers is supplied in the start method.
balst::StackTraceTestAllocator Now Usable With BSLMA_TESTALLOCATOR_EXCEPTION_TEST_BEGIN/END Macros¶
The BSLMA_TESTALLOCATOR_EXCEPTION_TEST_BEGIN and BSLMA_TESTALLOCATOR_EXCEPTION_TEST_END macros provide useful and important testing for exception neutrality. Previously these macros only worked with bslma::TestAllocator. This update, allowing the combination of these marcros with a balst::StackTraceTestAllocator, combines the power of the macros with convenient stack information made available by the allocator.
bslmt::ThreadLocalVariable Is Now Available For General Use on All Platforms¶
The platform restrictions on bslmt::ThreadLocalVariable have been relaxed.
