commit be9441b5147da8e66c84536b193bd4c0b9e3730a Author: Paul J. Davis <paul.joseph.da...@gmail.com> AuthorDate: Thu Jun 21 16:23:32 2018 -0500 Fix use of process_info(Pid, monitored_by) This can now return references that are from NIFs monitoring the process. This is important for the new file IO NIFs that monitor the controlling process. For now we'll just take the easy way out by filtering the references from our returned monitor lists. --- src/couch/src/couch_bt_engine.erl | 2 +- src/couch/src/couch_file.erl | 5 +++-- 2 files changed, 4 insertions(+), 3 deletions(-) diff --git a/src/couch/src/couch_bt_engine.erl b/src/couch/src/couch_bt_engine.erl index 43a77b0..7028997 100644 --- a/src/couch/src/couch_bt_engine.erl +++ b/src/couch/src/couch_bt_engine.erl @@ -185,7 +185,7 @@ decref(St) -> monitored_by(St) -> case erlang:process_info(St#st.fd, monitored_by) of {monitored_by, Pids} -> - Pids; + lists:filter(fun is_pid/1, Pids); _ -> [] end. diff --git a/src/couch/src/couch_file.erl b/src/couch/src/couch_file.erl index 9f668ea..af06b91 100644 --- a/src/couch/src/couch_file.erl +++ b/src/couch/src/couch_file.erl @@ -129,7 +129,7 @@ append_term_md5(Fd, Term, Options) -> append_binary(Fd, Bin) -> ioq:call(Fd, {append_bin, assemble_file_chunk(Bin)}, erlang:get(io_priority)). - + append_binary_md5(Fd, Bin) -> ioq:call(Fd, {append_bin, assemble_file_chunk(Bin, crypto:hash(md5, Bin))}, @@ -701,7 +701,8 @@ is_idle(#file{is_sys=true}) -> end; is_idle(#file{is_sys=false}) -> Tracker = whereis(couch_stats_process_tracker), - case process_info(self(), monitored_by) of + {monitored_by, PidsAndRefs} = process_info(self(), monitored_by), + case lists:filter(fun is_pid/1, PidsAndRefs) of {monitored_by, []} -> true; {monitored_by, [Tracker]} -> true; {monitored_by, [_]} -> exit(tracker_monitoring_failed);
