From 89886b4d2e6b99ba8d979e64eec52aa689f4ea66 Mon Sep 17 00:00:00 2001 From: Jesse Whitehouse Date: Wed, 24 May 2023 14:08:56 -0500 Subject: [PATCH 01/25] This is PECO-715. My loose plan is to follow the example patch included here: https://issues.apache.org/jira/browse/THRIFT-2033 This patch modifies thrift's transport/THttpClient.py PySQL already subclasses this in our sql/auth/thrift_http_client.py file So I should be able to apply the same patch there.
