grpcio-tools 1.13.0

Release v1.13.0

on Python PyPI

This is the 1.13.0 release (gloriosa) of gRPC Core.

Please see the notes for the previous releases here: https://github.com/grpc/grpc/releases. Please consult https://grpc.io/ for all information regarding this product.

This release contains refinements, improvements, and bug fixes, with highlights listed below.

Core

• gRPC stats will only be collected for debug builds or if GRPC_COLLECT_STATS is defined. It will be disabled for opt builds. (#15280)
• Fix for Issue #13553. Unlimited can now be set as the max receive message length. (#15394)

C++

• cmake install now also installs should also installs the roots.pem file (#15319)

C#

• Remove the workaround code to detect channel disconnects and rely on C core functionality instead. Note that there is a small change in behavior. Before, clients would detect disconnected channels immediately.
  (#14577)
• Provide debugging symbols for the grpc_csharp_ext native library used by the C# code. Only available for Windows currently. (#14908)
• Allow creating instances of ServerCallContext in tests (#15214)
• Fix handling of some less common situations in C# code generator (#15583, #15639)

Objective-C

• CFStream networking layer open for experiment (#15069, #15677, #15718)
• Fixed issue where BoringSSL podspec cannot be accessed from China (#15428, #15612)
• Bug fixes for gRPC Objective-C (#13180, #15050, #15285, #15429, #15531, )

PHP

• Experimental support for the client-side interceptor. (#13342, #15779)
• Add upper bound for the persistent channel per target, which can be set by the option ‘grpc_target_persist_bound’. By default, only 1 channel will be persisted for each target. (#15218)
• Add experimental API for the call invoker. (#15749)

Python

• Binary wheels for Python 3.7 on manylinux1 platform are now available.
• Source code is now Pylint 1.9.2-compliant (#15682).
• Testing utilities for gRPC Python are now readily available via grpcio-testing from PyPI (#15819).
• requirements.txt no longer lists the futures package as a dependency—whose installation used to be unnecessary on Python 3 but now actively breaks on Python 3 (#15362).
• Python errors have become more verbose. They now surface the actual error from gRPC Core: #13689
• GRPC_ENABLE_FORK_SUPPORT=false is no longer required when running fork-exec.
• Relying on an explicit with statement or explicitly calling Channel.close to release the underlying resources in Channel objects is now a required coding practice starting in v1.13.0.
