BDE 3.30.0 Highlights

BDE Buildable with gcc in C++17 Mode

BAEL Decorated with BSLS_DEPRECATE

In this release, the BSLS_DEPRECATE macro has been applied to (almost) every class in BAEL, a long deprecated package. (See BALL: The Open Source Logging Toolkit in BDE 3.9.0: Production Release). Clients who are using a supporing compiler and wish to receive compiler warnings if these classes are used should define the BB_WARN_ALL_DEPRECATIONS_FOR_TESTING_ONLY flag in their build environment. As the name of that flag implies, use of that build flag in production is disallowed. For additional details see bsls_deprecate.

Other components in the BDE libraries (outside of BAEL) will be marked deprecated using bsls_deprecate based on our experience with BAEL.

Behavioral Change: Default JSON Encoding of Decimal64 Values

BDE Release 3.30 introduces the previously alerted behavioral change in JSON encoding of Decimal64 values. The default value of the encodeQuotedDecimal64 attribute of the baljsn::EncoderOptions class is changed from false to true. Consequently, code that previously encoded bdldfp::Decimal* values to JSON using baljsn::Encoder with a default configuration will no longer encode those values as numbers. Now, they will be encoded in the quoted form (i.e., string literals).

The baljsn::Decoder implicitly decodes values given either representation, so existing users will notice no difference. However, users of other decoders that lack this behavior will experience breakage. In that case, users can either:

• Change their (non-BDE) decoder to accept the quoted string form, or

• Change their encoder to generate the numeric form by supplying a baljsn::EncoderOptions object in which the encodeQuotedDecimal64 attribute has been set to false.
