title: "Site Update: I Fixed the Patron Page"
|
||||
date: 2022-05-18

|

|
||||
So I fixed [the patron page](https://christine.website/patrons) and the
|
||||
underlying issue was stupid enough that I feel like explaining it so you all can
|
||||
learn from my mistake.
|
||||
|
||||
<xeblog-conv name="Numa" mood="delet">For those of you playing the christine dot
|
||||
website home game, look

||||
[here](https://github.com/Xe/site/commit/e2b9f384bf4033eddf321b5b5020ac4847609b37)

to see the fix and play along!</xeblog-conv>

My blog is basically a thin wrapper around two basic things:
|
||||
|
||||
1. Markdown files (such as for this article you are reading right now)
|
||||
2. Static files (such as for the CSS that is making this article look nice)
|
||||
|
||||
When I create a package out of my blog's code, I have a layout that resembles
|
||||
the directory structure in my git repo:
|
||||
|
||||
```console
|
||||
$ ls -l /nix/store/crc94hqyb546w3w9fzdyr8zvz3xf3p1j-xesite-2.4.0
|
||||
total 64

||||

|
||||
|
||||
The main problem is that my site expects all of this to be in the current
|
||||
working directory. In my site's systemd unit I have a launch script that looks
|
||||
like this:
|
||||
|
||||
```nix
|
||||
script = let site = packages.default;
|
||||
in ''
|
||||
export SOCKPATH=${cfg.sockPath}
|
||||
export DOMAIN=${toString cfg.domain}
|
||||
cd ${site}
|
||||
exec ${site}/bin/xesite
|
||||
'';
|
||||
```
|
||||
|
||||
However the Nix store isn't writable by user code. My patreon API client looked
|
||||
for its credentials in the current working directory. When I set it up on the
|
||||
target server I put the credentials in `/srv/within/xesite/.patreon.json`,
|
||||
thinking that the `WorkingDirectory` setting would make it Just Work:
|
||||
|
||||
```nix
|
||||
WorkingDirectory = "/srv/within/xesite";
|
||||
```
|
||||
|
||||
But this was immediately blown away by the `cd` command on line 4 of the script.
|
||||
|
||||
I have fixed this by making my Patreon client put its credentials in the home
|
||||
directory explicitly with this fragment of code:
|
||||
|
||||
```rust
|
||||
let mut p = dirs::home_dir().unwrap_or(".".into());
|
||||
p.push(".patreon.json");
|
||||
```
|
||||
|
||||
This will make the Patreon credentials get properly stored in the service's home
|
||||
directory (which is writable). This will also make the patrons page work
|
||||
persistently without having to manually rotate secrets every month.
|
||||
|
||||
Here's a good lesson for you all, make sure to print out the absolute path of
|
||||
everything in error messages. For the longest time I had to debug this from this
|
||||
error message:
|
||||
|
||||
```
|
||||
patrons: xesite::app: ".patreon.json" does not exist
|
||||
```
|
||||
|
||||
I was looking at the directory `/srv/within/xesite` and I saw it existing right
|
||||
in front of my eyes. This made me feel like I was going crazy and I've been
|
||||
putting off fixing it because of that. However, it's a simple fix and I was
|
||||
blind.
