bash 127 errors after upgrade and other install errors

bash 127 errors after upgrade and other install errors

[Henry Goss]

Hello,

I seem to be getting numerous bash error code 127 errors after updating

It seems to be happening on things like python and MySQL. The processes just return blank

Ex:

Myql
#returns blank
>

"echo $?"
> 127

Additionally,  old software I've been using for a while now fail (sort of), involving python and selenium and chrome/gecko driver

Two python processes get started , which both appear to be attempting to read from the same pipe (I think?)

Closing one of the processes will let the program continue, closing the other causes the main execution to stop.

127 errors go away with a fresh install, the python/selenium halting issue does not.

Are these related, and is there a fix?

Could you please provide the steps to reproduce the problem?

Thanks for the report.

I could not reproduce the problem 1).

As for the problem 2), it seems to be the same problem with
https://www.cygwin.com/ml/cygwin/2020-01/msg00093.html.

I already submitted a patch for that issue:
https://www.cygwin.com/ml/cygwin-patches/2020-q1/msg00010.html.

I confirmed the problem 2) is fixed with this patch.

Please wait for the new cygwin release.

Thanks. Thought I was going nuts.


In the case of 1) I’ll see if I can narrow down the process to reproduce.

Worst case I can do a reinstall and solve it.

For empty output and sudden death of the apps, the possible cause is an
injected third party library. AKA "BLODA".
