VMware GemFire® Native Client 10.1 Documentation
Published June 5, 2020.
The VMware GemFire® Native Client is a library that provides access for C++ and Microsoft® .NET™ clients to a VMware GemFire distributed system.
The Release Notes, below, describe new features and list issue resolutions for both C++ and .NET clients.
The C++ and .NET clients are documented in separate user guides:
See the API docs for API details:
See the VMware GemFire® User Guide for information regarding the server.
VMware GemFire® Native Client 10.1 is based on Apache Geode 1.11.
Version 10.1 includes a number of improvements:
- SSL enhancement - support for certificate chaining, better one-way SSL consistency
- Compatibility issues with various versions of PCC
- Performance improvements
- Bug fixes. See Issues Resolved in Native Client 10.1
The Apache Geode community has a host of examples based on the latest C++ and .NET APIs (https://github.com/apache/geode-native/tree/develop/examples).
This section describes issues resolved in VMware GemFire® version 10.1 and its patch releases, beginning with the most recent release.
GEODE-7930: Endpoint names are no longer truncated to 99 characters. The Native Client now supports endpoint names that meet the RFC 2181 standard of 255 characters for fully-qualified domain names. This solution also corrects a spurious “Failed to add endpoint” error that was issued when, in fact, no error had occurred.
GEODE-8015, GEMNC-470: Added debugging symbols to the released libraries. The Native Client release for Windows now includes a .pdb symbol file. On Linux, the symbols are now embedded in the shared library (.so file).
GEODE-3415: Added support for certificate chain files in SSL configuration.
GEODE-7437: Enforced recognition of trust store in one-way SSL.
GEODE-5708, GEMNC-465: Fixed an issue with an overly-aggressive memory free-up operation in partitioned regions that caused the putAll() operation to fail when called a second time due to a closed server connection.
GEODE-6576: Improved handling of stale connections to partitioned regions.
GEODE-6624, GEMNC-438: Improved handling of data serialization error reporting by fixing a problem caused by nested exceptions.
GEODE-6800, GEMNC-448: Fixed a gcc compilation error related to CacheableFileName objects.
GEODE-6835, GEMNC-442: Added retry logic to prevent spurious server-side SecurityManager errors.
GEODE-7019: Fix closing of idle connections in native client.
GEODE-7061: Reduced the number of connections created during high load conditions with many threads.
GEODE-7299: Fixed a memory leak associated with PDX data serialization.
GEODE-7316: Fixed a race condition that could cause a client app to crash on shutdown.
GEODE-7418, GEMNC-464: Fixed an issue with PDX serialization/deserialization of JSON objects.
GEODE-7476, GEODE-7509, GEMNC-436: Fixed a memory leak that appeared during repeated queries.
GEODE-7783: Optimized connection handling to improve performance.
