Ui.UiServer Error 500: UiWSGIHandler error: BrokenPipeError: Broken pipe

[HelloZeroNet]

Have you noticed any problem during browsing the network or you just see the errors in the console?

[canewsin]

I didn't notice any difference during browsing sites, but my suggestion is error should be informative, on error page it shows only error, stack trace is from different page.

[HelloZeroNet]

Yeah we have to find why is it happening, but probably it's not related to any request as you can do multiple requests from one socket. The error means the socket closed in an unexpected way, so the request is already done and it was idle. (keep-alive)

[canewsin]

This happens every time, when I start ZeroNet, I think at start only.

@HelloZeroNet i am not using Android as OP but on Windows 10 when i clicked to update zeronet (i do not remember the revision, maybe 4461) on py3 updater zite, then i received same error as OP.

ERROR Site:1uPDaT..NACf WebSocket receive error: ConnectionAbortedError: [WinError 10053] Software v hostitelském počítači ukončil vytvořené připojení in core/src/Ui/UiWebsocket.py line 71 > ... > lib/gevent/_socket3.py line 378

ERROR - Unhandled exception: BrokenPipeError: [WinError 10058] Požadavek odeslání nebo příjmu dat nebyl povolen, protože soket již byl v tomto směru vypnut předchozím vypínacím voláním in lib/gevent/pywsgi.py line 976 > ... > lib/gevent/_socket3.py line 439

these lines was quite at the end of the debug.log now after starting zeronet i see i am on rev4467. I clicked to update again, and error 500 no longer there, but only these errors.

[HelloZeroNet]

I have added the brokenpipe error to log as warning in Rev4469: https://github.com/HelloZeroNet/ZeroNet/commit/f41d02203862361cfc92e84eadeb0fc4c82065fb

I also fixed the peer save error based on the log file.

@slrslr Does the error happens on normal shutdown or on when you are updating? Does it restarts despite the error or it freezes in this state?

[purplesyringa]

The interesting part is that the traceback shows that the error happens when there's no websocket connection, i.e. when WebSocketHandler just proxies the calls to WSGIHandler.

@HelloZeroNet

Does the error happens on normal shutdown or on when you are updating? Does it restarts despite the error or it freezes in this state?

When i normal shutdown or update (on updater zite) i seen ERRORs like these Despite errors, the shutdown completed and also the update with restart completed.

Note that during shutdown invoked by the update, the last lines was: INFO - All server stopped INFO Site:1RivER..tdBN [FAILED] ...:31153: None INFO Site:1RivER..tdBN [FAILED] ...:15441: None INFO Site:1RivER..tdBN [FAILED] ...: None INFO Site:1RivER..tdBN [OK] ...: File not changed 1/3 INFO Site:1RivER..tdBN [FAILED] ...: None (errors linked above was there too, but was right before these lines)

i am now in r4469. when i tried to shutdown in this version too and same errors appeared like in previous revision. After the line "All server stopped" was one more last line: ERROR Db#0:Chart Commit error: OperationalError: cannot commit - no transaction is active in core/src/Db/Db.py line 169 (reason: Interval)

During update shutdown (no new update was found) there was again same errors and also following at the very end: INFO - All server stopped INFO Site:1FXYns..Rwtc [OK] iphere:port: Thanks, file content.json updated! 1/1
