org-web-tools-archive-attach fails: Cannot open: File name too long

[nico202]

Hi, I was trying to archive this page and org-web tools-archive-attach failed: https://wasaiya.com/%e6%b5%b4%e8%a1%a3%e3%81%ae%e4%bb%95%e7%ab%8b%e3%81%a6%e3%80%80%e5%8d%98%e8%a1%a3%e3%81%ae%e4%bb%95%e7%ab%8b%e3%81%a6%e2%91%a4/

The problem is, it's trying to compress this folder whose name is too long: /tmp/org-web-tools-archive-9SciAV/https%3A%2F%2Fwasaiya.com%2F%25e6%25b5%25b4%25e8%25a1%25a3%25e3%2581%25ae%25e4%25bb%2595%25e7%25ab%258b%25e3%2581%25a6%25e3%2580%2580%25e5%258d%2598%25e8%25a1%25a3%25e3%2581%25ae%25e4%25bb%2595%25e7%25ab%258b%25e3%2581%25a6%25e2%2591%25a4%2F--9SciAV.tar.xz

my workaround was to modify org-web-tools-archive--wget-tar and with

(substring (url-hexify-string url)  0 (min 30 (length (url-hexify-string url))))

(30 is just a short number I decided to try, as 100 was still too much)

Most filesystems have very long filename length limits. What filesystem are you trying to save it on?

[nico202]

I guess the problem does not depend on the filesystem, rather on tar limiting filenames in archive to 256 bytes
The fs is ext4
Thanks!

I think we need to start over. Please provide an exact copy of the error message.

Thanks, I also get the same error when calling touch with that filename.

This package has been around for a number of years without that bug having been reported, so I guess it isn't common, but I guess we should implement some kind of fix or workaround for it. I probably won't have time to work on this soon, so patches welcome.
