From 3d2322898883d6901a151ad432f223a7bfeb4b8e Mon Sep 17 00:00:00 2001 From: Albert Louis Rossi Date: Mon, 2 Oct 2023 08:32:46 -0500 Subject: [PATCH] dcache-bulk: add admin command and query to reset all requests with failed targets Motivation: There exists an admin command to reset requests to be rerun. The command takes various options based on the fields in the bulk request table. However, it is currently not possible to rerun only the requests with failed targets that have completed. This may sometimes be useful to the admin. (Note that for safety we do not automatically do this on service restart/reload, where only incomplete requests are reset). Modifications: Add the command and a few extra pieces of support in the dao/store layers. Result: We can now retry completed requests which have failed targets.
