From c60e4dc1095ef90a790582cacfad27c972637bb2 Mon Sep 17 00:00:00 2001 From: Royce Remer Date: Tue, 29 Oct 2024 22:41:55 -0700 Subject: [PATCH] Add new [lfs_client].BATCH_SIZE and [server].LFS_MAX_BATCH_SIZE config settings. (#32307) This contains two backwards-compatible changes: * in the lfs http_client, the number of lfs oids requested per batch is loaded from lfs_client#BATCH_SIZE and defaulted to the previous value of 20 * in the lfs server/service, the max number of lfs oids allowed in a batch api request is loaded from server#LFS_MAX_BATCH_SIZE and defaults to 'nil' which equates to the previous behavior of 'infinite' This fixes #32306 --------- Signed-off-by: Royce Remer Co-authored-by: wxiaoguang --- custom/conf/app.example.ini | 8 ++++++++ modules/lfs/http_client.go | 5 ++--- modules/setting/lfs.go | 21 +++++++++++++++++---- modules/setting/lfs_test.go | 16 ++++++++++++++++ services/lfs/server.go | 5 +++++ 5 files changed, 48 insertions(+), 7 deletions(-) diff --git a/custom/conf/app.example.ini b/custom/conf/app.example.ini index 0c76bbc6cde..69b57a8c012 100644 --- a/custom/conf/app.example.ini +++ b/custom/conf/app.example.ini @@ -324,6 +324,10 @@ RUN_USER = ;
