In stats_dump_proxy_to_buffer() function, special care was taken when dealing with servers dump. Indeed, stats_dump_proxy_to_buffer() can be interrupted and resumed if buffer space is not big enough to complete dump. Thus, a reference is taken on the server being dumped in the hope that the server will still be valid when the function resumes. (to prevent the server from being freed in the meantime) While this is now true thanks to: - "BUG/MINOR: server/del: fix legacy srv->next pointer consistency" We still have an issue: when resuming, saved server reference is not dropped. This prevents the server from being freed when we no longer use it. Moreover, as the saved server might now be deleted (SRV_F_DELETED flag set), the current deleted server may still be dumped in the stats and while this is not a bug, this could be misleading for the user. Let's add a px_st variable to detect if the stats_dump_proxy_to_buffer() is being resumed at the STAT_PX_ST_SV stage: perform some housekeeping to skip deleted servers and properly drop the reference on the saved server. This commit depends on: - "MINOR: server: add SRV_F_DELETED flag" - "BUG/MINOR: server/del: fix legacy srv->next pointer consistency" This should be backported up to 2.6
