Almost two years ago, in Jan 2023 I migrated from my Fediverse presence from my
|
||
|
self-hosted [Pleroma] instance to a single user Mastodon instance hosted by
|
||
|
[masto.host]. Since then I've wanted to retire the Pleroma instance, but I
|
||
|
didn't want to just take it offline. I wanted to preserve my posts and
|
||
|
links to them. That became a priority over the weekend so I built a
|
||
|
tool, `pleroma-archive` to do it.
|
||
|
|
||
|
<!-- more -->
|
||
|
|
||
|
A few months after the switch to Mastodon I tried pulling my posts via RSS hit
|
||
|
a runtime error. [I reported it to the project][runtime-error] but nothing came
|
||
|
of it.
|
||
|
|
||
|
I ignored it for another 18 months until this weekend when I tried to
|
||
|
upgrade my PostgreSQL server from version 12 to 16 and migrate it to a new
|
||
|
host. I chose the dump and load method of doing this but when restoring the Pleroma
|
||
|
database it appeared to get stuck building one of the indexes. I eventually
|
||
|
concluded that it was going to take something like 30 hours to complete. [I'm
|
||
|
not the first one to hit this problem either][pg-restore].
|
||
|
|
||
|
Retiring Pleroma had now become a priority. I discovered that there was now an
|
||
|
account backup option in the import/export section of the settings. I
|
||
|
downloaded my archive and set about building a tool that could generate a
|
||
|
website from it.
|
||
|
|
||
|
As usual I built the tool in Rust, my scripting language of choice. It's
|
||
|
imaginatively called `pleroma-archive`. It generates an index page of all posts
|
||
|
as well as a page for each individual post. The public URLs that Pleroma uses
|
||
|
are not part of the archive, so for each post the tool does a `HEAD` request
|
||
|
with the post id to determine the public URL of the post. The results of this
|
||
|
are cached so it only needs to do it once for each post.
|
||
|
|
||
|
With a little bit of help from [Nginx try\_files][try_files] a page like
|
||
|
`notice/ARQGKLTJNiP8Lu2gT2.html` can be served at `/notice/ARQGKLTJNiP8Lu2gT2`,
|
||
|
matching the URL it had when served by Pleroma:
|
||
|
|
||
|
```nginx
|
||
|
location / {
|
||
|
try_files $uri $uri/index.html $uri.html =404;
|
||
|
}
|
||
|
```
|
||
|
|
||
|
The end result is at <https://decentralised.social/>.
|
||
|
|
||
