Proper mirroring
April 29th, 2018
----------------------------------------
A few folks were kind enough to let me know that my recent
experiments with tor [0][1] broke my gopher hole mirrored on SDF
and tilde.town. In reality, those mirrors weren't all that useful
in the first place. All the links in my gophermaps to internal
resources were using full, complete hostnames & ports. Thus, if
you went to SDF, after link #1 you were really over on
gopher.black anyway.
[0] gopher.black on tor, part 1
[1] gopher.black on tor, part 2
This wasn't ideal, but it was low priority. It worked well enough,
right? When I removed the explicit hostname & port info from
gophermaps to allow my dual server goodness for tor, suddenly SDF
and tilde.town thought that my links were legitimately local.
There was just one problem... my content paths are different on
all three systems.
On gopher.black, / is mine. Everything starts there.
On SDF, /users/tomasino is mine.
On tilde.town, /~tomasino is mine
The fix didn't take a ton of work since I already had a pretty
solid foundation for mirroring the content. I have a local copy of
my gopher git repo on those boxes and a cron-job that pulls it
four times a day. Simple! Well, now I have a little extra goodness
in there.
The update process looks like so:
- Fetch the remote
- Check the SHA of the latest commit in HEAD vs origin/master
- If different:
- force reset the local head
- pull origin/master
- find all gophermaps and use sed to replace root paths
- touch the local folder (for SDF's phlog list)
Here's the code [2]:
[2] sdf-update-gopher
It's not the cleanest. I could remove the pushd/popd stuff. It's
legacy from a much more complex process time. The sed command is
cumbersome as well. I could have matched \t/[^\t]*$ instead, but
it works. So, like most of my stuff... good enough.
A final note:
Moku Pona & my reading lists are local cron tasks on gopher.black
that update quite often. To avoid a bajillion commits to my gopher
repo I don't include them at all. That means my moku-pona list and
reading lists are not available on SDF or tilde.town. All the rest
of the goods are there, though.
Enjoy & stuff!
