BDE 3.99.6 Release

Schedule

• The BDE team announces that the BDE 3.99.6 production release was completed on Thursday, May 19, 2022.

BDE 3.99.6 Highlights

PCRE2 update

The PCRE2 library (used by bdlpcre::Regex) was upgraded to version 10.39.

Remove *ByCategory Introspection Indirection in bal Codecs

A recent change to the BDE JSON and XML codecs simplified their respective object visitors by removing code that manually checked and dispatched on the type category of sub-objects, and instead used the bdlat_TypeCategoryUtil::accessByCategory and manipulateByCategory function templates. Unfortunately, delegating to these utility operations increased the number of function template instantiations enough per introspected object that several client programs coding extremely large message types could no longer be compiled with Sun CC and/or XLC due to the compilers running out of memory.

This release logically reverses this refactoring, by manually inlining the operations and removing levels of indirection.

Continued Addition of C++17 Type Aliases

This release adds bsl:: aliases for the C++17 features in bsl_cmath.h, bsl_memory.h, bsl_mutex.h, and bsl_new.h. This is part of the general effort to simplify the use of bsl:: names, and in general better support C++17.

Continued Work to Support GCC-11 and C++20

This release continues to address build and test failures for supporting BDE for both C++20 and gcc-11 (for various language flavors).

Fixed requests: 3.99.6
