LDA 2a09bd7156 [ADD/WIP] Test out LMDB
Separate branch because I'm mainly testing reliability. Seek out
lda/Cytoplasm's lmdbwerk branch for the base upstream(with mem-moment's
Memory.c impl to apply)

# Parsee - the jealous XMPP<=>Matrix bridge
Parsee is a Matrix<=>XMPP bridge written in C99, with Cytoplasm, similar to Bifrost,
but it is NOT a drop-in replacment.
## Why?
### Naming
The name 'Parsee' is actually a reference to [Parsee Mizuhashi](https://en.touhouwiki.net/wiki/Parsee_Mizuhashi), a
"*bridge* princess".
### Reasoning (personal to LDA)
I hate Bifrost. I also wanted to dip my toes in XMPP, XML, and bridges a bit. Also, as a sister project to KappaChat,
this means that I can integrate Parsee with KappaChat however I wish it to be, which allows me to mess around with a
codebase I'm already familiar with.
### "Why not just use Matrix lol"
### "Why not just use XMPP lol"
These two having the same answer should be enough information. Also can I *just* have fun?
One could also argue that both sides need to migrate(onboard) the other side, so
a bridge may be a good way to start.
## BUILDING
```sh
$ make # This generates a 'parsee' executable.
$ cd tools # If you want to build more tools
$ make && cd ..
$ make ayadoc # If you want to build HTML documentation
# make [PREFIX=(install path)] install # To install Parsee.
```
If there are any Cytoplasm-related build failures, you may want to check the Makefile to
change a few variables (you can set `CYTO_INC` and `CYTO_LIB`)
### DEPENDENCIES
Parsee tries to avoid dependencies aside from [Cytoplasm](https://git.telodendria.io/Telodendria/Cytoplasm).
## RUNNING
First off, you may want to configure Parsee by running the `config` tool(generally named
`parsee-config` in most cases), with the correct flags, like here.
```sh
parsee-config \
-d data/ \
-m 'https://media.blow.hole/' \ # You will need to reverse proxy media.blow.hole to point
# to Parsee (port 7642)
-H 'blow.hole' \ # Matrix homeserver name
-J 'parsee.blow.hole' \ # XMPP component host, must be reachable
-s 'A very secure XMPP component secret' \
-p 5347
```
If everything goes well, it should generate a `parsee.json` file.
To start Parsee, run it in the same directory as the `parsee.json`. It should start properly
and produce a `parsee.yaml` file, which you can chuck into your Matrix homeserver. To test
if the homeserver can talk to Parsee, try reaching it over HTTP at the port 7642. If it returns
with a landing page, then this side works. You can read it for some more information.
## DOCS
TODO
## TODOS
- Add [libomemo](https://github.com/gkdr/libomemo) as an optional dependency.
- It depends on more stuff anyways, and I don't want to weigh down the
dependency list of Parsee for that.
- Matrix's libolm is deprecated. They replaced it with a Rust version that
pulls in *way too many* dependencies, and that lacks a C binding. We may
put in the work of either forking off libolm or making a binding to KappaChat.
~ Mess with Cytoplasm to make it have support for something like LMDB as an
*optional* dependency. This should increase reliability and speed for anyone.
v Work is going on on the Cytoplasm `lmdbwerk` and this branch to get LMDB.
- Nesting might be an issue we'll need to deal with. libdb and Berkley DB
seem to lack support for them. If we can shove entries at specific indices,
we _might_ just manage to get some system that can at least emulate that,
and hopefully be reasonably faster than the filesystem, with some added
reliability.
- You can always concat paths, and search by prefix with LMDB. ~512 bytes
a key is more than enough. I'll just need to write a good abstraction layer.
- Get rid of the '?'-syntax and use another invalid Matrix char/valid XMPP char
('$'?) for escaped
- PROPER FUCKING AVATARS
XEP-0084 IS THE WORST PIECE OF SHIT KNOWN TO MAN. If any Jabberbros want to
look at terrible code/XML and suggest things to have *proper* avatar support,
I'm all in.
- Consider making room/MUC admins/owners be able to plumb instead of it being
restricted to Parsee admins, with permission from MUC owners, too
- Limiting to admins may be a way to "control" consent for both, but this is
only if Parsee admins are good-willed, which we must assume such statment to
be false by default.
- Look at XEPS-TBD.TXT for XEPs to be done
- Manage MUC DMs in a reasonable manner. Thanks `@freeoffers4u:matrix.org` for being
a fucking annoyance and DMing an old Parsee semi-anon user for no clear reason.
## DONATING/CONTRIBUTING
If you know things about XMPP or Matrix, yet aren't familiar with C99, or just
want to suggest a feature, you may open an issue.
Packaging Parsee (and Cytoplasm) for your specific platform might be a nice to have,
to make Parsee easier to setup and manage.
**(DON'T FOR NOW, THERE IS LITERALLY NOWHERE THIS GOES TO)**
You may also donate to [the LiberaPay](https://en.liberapay.com/Parsee), alongside
[Telodendria's](https://en.liberapay.com/Telodendria), as it is the project
currently maintaining Cytoplasm.
## IM chats
Please avoid asking for help/issues here. If you *really* want, you may just open
an issue and link it over it. Basic respect for others/not being an asshat is required.
(Also, these are temporary room aliases.)
