BDE 3.61.0: Production Release

Schedule

• The BDE team is pleased to announce that the BDE 3.61.0 production release was completed on Monday, Aug 24, 2020.

BDE 3.61.0 Highlights

New style of Allocator-Aware Component Interface Being Gradually Introduced

In the future, BDE allocator-aware components will allocate memory from a bsl::allocator<char> object rather than a bslma::Allocator pointer.

These changes are transparent to clients of the affected packages: bslma::Allocator* arguments can still be passed in and the correct conversions will occur.

The document describing this new approach is still a work in progress, and other teams should not yet adopt this development style, but if you wish to see what the new style will look like, you can take a look at components in baltzo and bdlb.

For example, here’s the difference in the default constructors in baltzo::Zoneinfo:

Older Style

#include <bslma_default.h>

// ....

 // CREATORS
 explicit Zoneinfo(bslma::Allocator *basicAllocator = 0);
     // Create a 'Zoneinfo' object having the values:
     //..
     //  numTransitions() == 0
     //  identifier()     == ""
     //..
     // Optionally specify a 'basicAllocator' used to supply memory.  If
     // 'basicAllocator' is 0, the currently installed default allocator is
     // used.

 // ....

 // ACCESSORS
 bslma::Allocator *allocator() const;
     // Return the allocator used by this object to supply memory.  Note
     // that if no allocator was supplied at construction the currently
     // installed default allocator is used.

New Style

#include <bslma_stdallocator.h>

// ....

 // TYPES
 typedef bsl::allocator<char> allocator_type;

 // CREATORS
 Zoneinfo();
 explicit Zoneinfo(const allocator_type& allocator);
     // Create a 'Zoneinfo' object having the values:
     //..
     //  numTransitions() == 0
     //  identifier()     == ""
     //..
     // Optionally specify an 'allocator' (e.g., the address of a
     // 'bslma::Allocator' object) to supply memory; otherwise, the default
     // allocator is used.

 // ....

 // ACCESSORS
 bslma::Allocator *allocator() const;
     // !DEPRECATED!: Use 'get_allocator()' instead.
     //
     // Return the allocator used by this object to supply memory.  Note
     // that if no allocator was supplied at construction the currently
     // installed default allocator is used.

 allocator_type get_allocator() const;
     // Return the allocator used by this object to supply memory.  Note
     // that if no allocator was supplied at construction the default
     // allocator in effect at construction is used.

baljsn::DatumUtil::decode methods now support depth-limiting

In order to make baljsn::DatumUtil::decode more robust, the methods limit the depth of nested array and object elements to 64 levels by default.

This default can be overridden by passing in an appropriately constructed baljsn::DatumDecoderOptions instance.

baljsn::DatumUtil behavior w.r.t. duplicate map keys clarified

The documentation for baljsn::DatumUtil now clarifies what happens if duplicate keys are present in a Datum being encoded (the first key/value pair is encoded, and the others are ignored) or in a JSON string being decoded (all key/value pairs will be present in the corresponding Datum map.

Fixed requests: 3.61.0
