From b54d5e19f068a73bdbde5a9434fe72902764b958 Mon Sep 17 00:00:00 2001 From: Pablo Sabater Date: Fri, 24 Jul 2026 12:54:15 +0200 Subject: [PATCH] fetch-pack: drop the static advertise_sid variable write_fetch_command_and_capabilities() is moved to 'connect.c' in a subsequent commit. To prepare for that, drop the static variable usage of advertise_sid. Currently advertise_sid is set in fetch_pack_config() by reading "transfer.advertisesid". It is used in three places: 1. In do_fetch_pack(), to clear it when the server lacks support: if (!server_supports("session-id")) advertise_sid = 0; 2. In find_common(), to advertise the session id over protocol v0/v1: if (advertise_sid) strbuf_addf(&c, " session-id=%s", trace2_session_id()); 3. In write_fetch_command_and_capabilities(), to advertise it over protocol v2: if (advertise_sid && server_supports_v2("session-id")) packet_buf_write(req_buf, "session-id=%s", trace2_session_id()); About 1, the check only guards the v0/v1 path, and the v2 path already checks server support inline in its condition. Follow the same pattern and fold the check into the condition in find_common(). About 2 and 3, replace the static variable with a local read via repo_config_get_bool() in each function. Because repo_config_get_bool() leaves advertise_sid as is if it is not set, initialize it to 0, matching its default.
