reporter Sorry, wrong wording, reference to old times. What I meant is it updates/refreshes automatically as soon as there are new data.
-
Please confirm: you are using mhttpd built-in https server and you use the mhttpd password file, yes? K.O.
-
I disabled the non-thread-safe read_passwords(). Can you update to the head of midas-2019-09 and try again? (the version you use is same as the midas-2019-09 branch right where it branched off “develop”). You can try “git pull; git checkout midas-2019-09-c”. K.O.

no feed back from bug reporter… hmm… K.O.

I will reenable re-reading the password file in mongoose616 as all password processing is now done in the main thread. K.O.

- changed status to resolved
I believe it is fixed by disabling non-thread-safe read_passwords(). Get latest midas-2019-09 for this fix. K.O.

Do not see the crash with macOS 10.13.6 - safari 12.1.2. But I am puzzled by the reference to “page auto reloads” - the messages page does not autoreload. (the old history page does autoreload, the new history plot page does not). K.O.
