User:Gregorlove.com/Changing permalinks

In 2015 I moved my site from Nucleus to ProcessWire. In the process, I decided to update my permalink URL structure. Below I will document problems and the solutions I've found.

Existing URLs

 * article permalinks used URL path
 * notes permalinks used URL path

New URLs

 * article permalinks will use URL path
 * notes permalinks will use URL path

Accessing Old URLs
The existing URL paths are stored along with each page in ProcessWire. The ProcessWire templates detect the old URL path and return a 301 redirect to the new permalink.

De-duping Webmentions

 * To uniquely identify and de-dupe webmentions, my code uses . Since the permalinks will be changing in my notes h-feed, I suspect bridgy will try to re-send recent webmentions to the new URLs. Since the md5 hash will be different, they will not be properly de-duped.
 * My solution: When migrating webmentions to ProcessWire, I re-calculated the hash to be . For example, instead of using http://gregorlove.com/2014/06/this-is-my-first-note/ in the hash, I will use gregorlove.com/2014/06/this-is-my-first-note/. Leaving the scheme off is a bit of future-proofing, since I intend to deliver all my pages https-only eventually.
