arclink "unexpected eof cmd" when requested via webdc3 #262

Closed filefolder closed 4 years ago

filefolder commented 4 years ago

noticing this error in the debug log when using the webdc3 client. in the web client request window it says "status: ERROR, size: 0, info: internal error"

a similar arclink bug had been posted/fixed here a few years back, attributed to "python wrapper issues", could it be the same problem? there are still some instances of "Config.Exception" in the code in various spots but it's all a bit over my head.

(current dev version)

quick update, replaced all instances of Config.Exception (but NOT _Config.Exception) with just Exception, did not appear to fix anything.

andres-h commented 4 years ago

"internal error" means an uncaught Python exception. It comes from here.

The "raise" statement should make sure that the exception is re-raised and stack trace is printed to stdout. You should find it in some log file (or try to run arclink in terminal). Without stack trace, it is impossible to say what went wrong.

Since ArcLink is deprecated, please also consider using FDSNWS instead of ArcLink. It is supported by the current WebDC version.

i see that arclink is now missing from the new version (whew) so happy to close this
