Salt manager, error downloading

[lukasc-ubc]

Dear @klayoutmatthias,

Several percent of my users have problems downloading using the package manager. We've seen this for the SiEPIC-Tools and the SiEPIC-EBeam-PDK packages. The errors occur for larger files - in this case, they are 9 MB in size. The solutions I've had are:

1. ask people to install the package using a different means (GitHub Desktop with a symbolic link so they can still receive updates).
2. remove the offending large files (which in this case would break the PDK).

This problem seems intermittent. I wonder if you have any advice?

Do you know if the issue is coming from a time-out somewhere if the download time is too long? Is this something that could be adjusted in KLayout?

thank you
Lukas

Hi Lukas,

actually this seems to be generated by a timeout (the message could be more intuitive). I hardcoded 10 seconds which appeared enough to me. Do you think it's likely that 10 seconds are exceeded?

I can easily extend it to something like 60 seconds. I just wonder if there is an upper limit. I think it's also possible - although harder - to implement infinite timeout with a way to cancel the download.

For my records: code is tlHttpStreamQt.cc, lines 421+

Best regards,

Matthias

Could this be a parameter that can be modified by script config variable, or OS environment, or software configuration window? Infinite with cancel would be nicest, but 30-60 s in the meantime would be better perhaps.

Sure, I'll take a look. I have not though 10 seconds would become a problem, but I could confirm that for big files there really is a latency in the order of seconds.

0.27.8 is released which should fix this problem.

You mean 60 seconds timeout is not enough?

I am also having issues with the package manager for SiEPIC-Tools. It seems to download all but one of the files, then it fails the whole installation :(

For reference the error says:
Error 404: Not Found, fetching https://github.com/siepic/SIEPIC-Tools.git/lvsn/bc/2680/tags/v0.4.0/klayout_dot_config/pymacros/Keybindings/Waveguides/Waveguide to Path %28forget waveguide type%29.lym

It could be because of the filename which contained ( and ). I changed the filename, and released v0.4.1. Can you please try again?

[wschulkins]

Works now! Thank you!
