bug#22145: 25.0.50; tramp and auto-revert tests hang on OS X

[Anders Lindgren]

Hi!

When executing the command line in a shell window, they terminate immediately without any output. Also, this is the case when running the individual `test' commands.

I mananged to get the "m" command working by placing the point on the "Q" in the ert status line, I have attached the result.

It's only part of the whole story (the last 1000 lines due to
message-log-max), but it helps.

Tramp hangs at this command:

This is a delicate command, because the file name is r2l encoded, and
one aim of the test is to check whether this works. OTOH, I see ^G
evidences in the trace after sending the command, so I don't know
whether Tramp really hangs, or whether this has been the place you have
started to interrupt the test.

Could you, pls, run the command in a shell buffer on your machine? At
this state of the test the file doesn't exist yet, so we could use a
shorter directory path. Something like

--8<---------------cut here---------------start------------->8---
# (test -e /tmp/\أ\ص\ب\ح\ \ب\و\س\ع\ك\ \ا\ل\آ\ن\ \ت\ن\ز\ي\ل\ \ن\س\خ\ة\ \ك\ا\م\ل\ة\ \م\ن\ \م\و\س\و\ع\ة\ \و\ي\ك\ي\ب\ي\د\ي\ا\ \ا\ل\ع\ر\ب\ي\ة\ \ل\ت\ص\ف\ح\ه\ا\ \ب\ل\ا\ \ا\ت\ص\ا\ل\ \ب\ا\ل\إ\ن\ت\ر\ن\ت || test -h /tmp/\أ\ص\ب\ح\ \ب\و\س\ع\ك\ \ا\ل\آ\ن\ \ت\ن\ز\ي\ل\ \ن\س\خ\ة\ \ك\ا\م\ل\ة\ \م\ن\ \م\و\س\و\ع\ة\ \و\ي\ك\ي\ب\ي\د\ي\ا\ \ا\ل\ع\ر\ب\ي\ة\ \ل\ت\ص\ف\ح\ه\ا\ \ب\ل\ا\ \ا\ت\ص\ا\ل\ \ب\ا\ل\إ\ن\ت\ر\ن\ت) && /bin/ls -w -ildn /tmp/\أ\ص\ب\ح\ \ب\و\س\ع\ك\ \ا\ل\آ\ن\ \ت\ن\ز\ي\ل\ \ن\س\خ\ة\ \ك\ا\م\ل\ة\ \م\ن\ \م\و\س\و\ع\ة\ \و\ي\ك\ي\ب\ي\د\ي\ا\ \ا\ل\ع\ر\ب\ي\ة\ \ل\ت\ص\ف\ح\ه\ا\ \ب\ل\ا\ \ا\ت\ص\ا\ل\ \ب\ا\ل\إ\ن\ت\ر\ن\ت

And if this hangs, mybe also the test -e ... and test -h ... command alone.
