grpcio 1.10.0

Release 1.10.0

on Python PyPI

This is the 1.10.0 release (glamorous) 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

• To provide a cleaner install with fewer public headers, several features of core have been removed from the surface or GPR API as they were not used in any wrapped language (except C++) or in external applications, such as:
  a. grpc_alarm (removed; the C++ grpc::Alarm now directly invokes core subsurface functions)
  b. gpr_join_host_port, gpr_cmdline, gpr_subprocess (moved to test/core/util)
  c. gpr_tls, gpr_avl (internalized)
  d. gpr_thd (internalized)
  • Except gpr_thd_id and gpr_thd_currentid, which remain public
• As a result of these changes, core is now at version 6.0.0
• Fix memory leaks in max_age_filter (#14501) and http_proxy (#14137)
• Changed resolver and LB policy APIs to C++
• Added re-resolution into grpclb policy (#14438).
• Extracted per LB-call data from grpclb policy (#13911)
• Fixed C-core to immediately take ownership of slices when a send_message op is started
• Fix a race condition causing freeze at shutdown with epollex polling strategy (#14177)
• Improvements in CMake: find_package (#14353)
• Portability fixes (#14136, #14198)
• Test infrastructure cleanup (#14117)
• Update BoringSSL submodule (#13948)
• Make RR re-resolve when any of its subchannels fail (#14170)
• DNS resolver caches results, allowing it to be hit arbitrarily often. Resolution frequency is controlled via channel arg GRPC_ARG_DNS_MIN_TIME_BETWEEN_RESOLUTIONS_MS. (#14228)

C++

• C++ headers are moved from include/grpc++ to include/grpcpp. Headers in include/grpc++ are deprecated (#14210)
• Experimental gRPC-C++ Cocoapods podspec (#13935)
• Improve comments explaining CompletionQueue ok result, Shutdown contract, and effect of TryCancel
• Explain in comments that GenericStub::Call is deprecated and that GenericStub users should prefer the two-phase call creation mechanism (first call PrepareCall then call Start) instead

C#

• Experimental support for client-side and server-side interceptors (#12613)

Objective-C

• Added base64 encoding support of binary header field for Cronet transport
• Fixed build time warnings (#14314)

PHP

• Added memory leak test

Python

• Strip the grpcio source package by removing some of the unneeded files pulled by submodules, decreasing the uncompressed size by about 10MB. (#14533)
• Relax the interceptor API’s requirement of providing a call details instance with all of the attributes specified as comments in the interface. The non-existent attributes will now reassume the values they previously had when they were passed to the interceptor. (#14105)

Ruby

• Fix a race condition in server shutdown (#14134)
• Fix a memory leak that occurs after an exception thrown due to invalid arguments (#14132)
