Saving Printer Configuration Causes Dropped HTTPS Connection #9

Closed sjoubani closed 2 years ago

sjoubani commented 3 years ago

Describe the bug When saving a printer's configuration (POST to /config), the server-side connection is dropped, though the process itself doesn't terminate.

To Reproduce Steps to reproduce the behavior:

  1. Built on macOS (10.15, libpng 1.6.37, libusb 1.0.24, libjpeg 9d, PAPPL 1.0.3, h-p-a 66aba65)
  2. Launch with "server" command
  3. Browse in Safari and add a printer
  4. Edit the printer's configuration (location, contact, etc)
  5. Save changes

Expected behavior POST succeeds and redirects to configuration page

Additional context This seems to be the only POST with this behavior, at least in this build

@sjoubani Can you provide a debug log from this? I suspect the issue is in how Apple has changed keychain security in macOS, and that the self-signed certificate is not accessible to the printer application, causing this failure.

@michaelrsweet The SSL connection works fine, and I've deliberately set HOME to a special location for the creation of .cups/ ssl.keychain. I've also set log-file and log-level as you requested to capture this: hp-printer-app.log

This seems to be fixed now.
