The limitation that only one simultaneous watch request over one wlink is possible was added in April (b4857f66) when both Watch and WatchLink locking was not there and marked as XXX. That locking was added in July (85d86a32) though, so there should be real need to simultaneous watch requests over one wlink. Also the limit implementation had a bug: it was setting handlingWatch back to 0, but _after_ sending reply to client. This way a situation was possible when client is woken up first, sends another watch request, wcfs was not yet scheduled, handlingWatch is still _1_, and watch request is rejected. This bug is very likely to happen when running wcfs tests with 2 CPU machine or with just GOMAXPROCS=2: C: setup watch f<0000000000000043> @at1 (03d2c23f46d04dcc) # pinok: {2: @at1 (03d2c23f46d04dcc), 3: @at0 (03d2c23f46c44300), 5: @at0 (03d2c23f46c44300)} S: wlink 6: rx: "1 watch 0000000000000043 @03d2c23f46d04dcc\n" S: wlink 6: tx: "2 pin 0000000000000043 #3 @03d2c23f46c44300\n" C: watch : rx: '2 pin 0000000000000043 #3 @03d2c23f46c44300\n' S: wlink 6: tx: "4 pin 0000000000000043 #2 @03d2c23f46d04dcc\n" S: wlink 6: tx: "6 pin 0000000000000043 #5 @03d2c23f46c44300\n" C: watch : rx: '4 pin 0000000000000043 #2 @03d2c23f46d04dcc\n' C: watch : rx: '6 pin 0000000000000043 #5 @03d2c23f46c44300\n' S: wlink 6: rx: "2 ack\n" S: wlink 6: rx: "4 ack\n" S: wlink 6: rx: "6 ack\n" S: wlink 6: tx: "1 ok\n" C: watch : rx: '1 ok\n' C: setup watch f<0000000000000043> (@at1 (03d2c23f46d04dcc) ->) @at2 (03d2c23f46e91daa) # pin@old: {2: @at1 (03d2c23f46d04dcc), 3: @at0 (03d2c23f46c44300), 5: @at0 (03d2c23f46c44300)} # pin@new: {2: @at2 (03d2c23f46e91daa), 3: @at2 (03d2c23f46e91daa), 5: @at2 (03d2c23f46e91daa)} # pinok: {2: @at2 (03d2c23f46e91daa), 3: @at2 (03d2c23f46e91daa), 5: @at2 (03d2c23f46e91daa)} S: wlink 6: rx: "3 watch 0000000000000043 @03d2c23f46e91daa\n" S: wlink 6: tx: "0 error: 3: another watch request is already in progress\n" C: watch : rx: '0 error: 3: another watch request is already in progress\n' C: watch : rx fatal: 'error: 3: another watch request is already in progress' C: watch : rx: '' If we would need to maintain the limit, we should move setting handlingWatch=0 just before sending final reply to client, but since the need for the limit is not there anymore, let's fix it by removing the limit altogether.
