Aparent the path to the socket is too long - I wasn't aware of a limit that would occur in practical circumstance, will need to find out what the restrictions are.

Could you edit zim/main/ipc.py and put in "print SERVER_ADDRESS % COUNTER" before line 98 ?

Work around is to run zim with "--standalone"

THanks,

Jaap

--standalone works

Add the print:

for 0 through 99

[Jaap Karssenberg (jaap.karssenberg)]

Thanks, looks indeed that the total path is too long.

The socket name of zim itself is a bit long due to the hex key I put in there, but also the path to the tmp folder "/var/folders/g9/nm8_blpd5hx0vlhmc3x45h340000gn/T/" is quite long.

I would expect something like "/tmp/" there. Do you know why it is such a weird folder name?

If the theory holds, setting TMP environment to "/tmp" should work.

Alternative modifying "ipc.py" and change on line 60

 SERVER_ADDRESS = str(zim.fs.get_tmpdir().file('primary-%s' % version).path)

into

 SERVER_ADDRESS = str(zim.fs.get_tmpdir().file('primary').path)

should also work.

Regards,

Jaap

I've read that /var/folder is a temporary folder that survives reboot on MacOS.

I don't have a $TMP but I see

hom:~$ echo $TMPDIR
/var/folders/g9/nm8_blpd5hx0vlhmc3x45h340000gn/T/

Other Mac users would likely have this problem, so I suggest a change in zim itself rather than me setting an environmental variable.

[Jaap Karssenberg (jaap.karssenberg)]

Of course, but would like to confirm that reducing the path length indeed
fixes the issue.

Regards,

Jaap

Sorry, yes, it worked. If you want some uniqueness, maybe you could truncate the hex key to 6 chars...?

[Jaap Karssenberg (jaap.karssenberg)]

Went with 8, but same idea :)

Fix is in ab219153f92a92a9a4949ecccf0939f0cc2e6433

I am suggesting to try "Long Path Tool" program.
