[pve-devel] [PATCH corosync-pve 07/10] build: move some patches into debian/

Wed Nov 7 14:26:34 CET 2018
otherwise building a source package is not possible, since the upstream
files would get dirtied by preparing the build directory.

++Patch tries to fix incorrect behaviour during following test-case:
++- 3 nodes
++- Node 1 is paused
++- Node 2 and 3 detects node 1 as failed and informs CPG clients
++- Node 1 is unpaused
++- Node 1 clients are informed about new membership, but not about Node 1
++ being paused, so from Node 1 point-of-view, Node 2 and 3 failure
++
++Solution is to:
++- Remove downlist master choose and always choose local node downlist.
++ For Node 1 in example above, downlist contains Node 2 and 3.
++- Keep code which informs clients about left nodes
++- Use joinlist as a authoritative source of nodes/clients which exists
++ in membership
++
++This patch doesn't break backwards compatibility.
++
++I've walked thru all the patches which changed behavior of cpg to ensure
++patch does not break CPG behavior. Most important were:
++- 058f50314cd20abe67f5e8fb3c029a63b0e10cdc - Base. Code was significantly
++ changed to handle double free by split group_info into two structures
++ cpg_pd (local node clients) and process_info (all clients). Joinlist
++ was
++- 97c28ea756cdf59316b2f609103122cc678329bd - This patch removed
++ confchg_fn and made CPG sync correct
++- feff0e8542463773207a3b2c1f6004afba1f58d5 - I've tested described
++ behavior without any issues
++- 6bbbfcb6b4af72cf35ab9fdb4412fa6c6bdacc12 - Added idea of using
++ heuristics to choose same downlist on all nodes. Sadly this idea
++ was beginning of the problems described in
++ 040fda8872a4a20340d73fa1c240b86afb2489f8,
++ ac1d79ea7c14997353427e962865781d0836d9fa,
++ 559d4083ed8355fe83f275e53b9c8f52a91694b2,
++ 02c5dffa5bb8579c223006fa1587de9ba7409a3d,
++ 64d0e5ace025cc929e42896c5d6beb3ef75b8244 and
++ b55f32fe2e1538db33a1ec584b67744c724328c6
++- 02c5dffa5bb8579c223006fa1587de9ba7409a3d - Made joinlist as
++ authoritative source of nodes/clients but left downlist_master_choose
++ as a source of information about left nodes
++
++Long story made short. This patch basically reverts
++idea of using heuristics to choose same downlist on all nodes.
