This allows us to get rid of the hideous MATRIX_PATH_PART_EQUALS macro,
and prevents inconsistent usage of strcmp() (for example, !strcmp() vs
strcmp() == 0).
StrEquals() also has sensible behavior for dealing with NULL strings (it
doesn't just segfault like strcmp()).
This is a very early prototype. It works, but it is probably not efficient
or reliable. However, the documentation format it parses is stable, so I
will begin moving the documentation into the headers.
This implementation is loosely inspired by the original paper on the
Mersenne Twister, and borrows code from a public-domain implementation of
it, adapting it to fit the style of Telodendria's code, and fixing a few
bugs regarding the size of the data type used.
Neither C nor POSIX provide a good, thread-safe pseudorandom number
generator. The OpenBSD linker started complaining about the use of
rand_r(), and no standard alternative presented itself as worthy of
consideration, so I finally decided it was time to roll my own PRNG.
This is useful for having a TLS and a non-TLS version port, like Synapse.
I verified that the multiple-servers does in fact work as intended,
although the TLS server part is broken; I must be doing something
incorrectly with LibreSSL in setting up the server.
These functions previously operated on the assumption that fgetc() would
block; however it will not block on HttpServer streams because those are
non-blocking. They now check error conditions properly before failing
prematurely.
You might be asking why I would just write a simple curl replacement
when curl does the job just fine. Well, the most immediate reason is
to test the HttpClient API, but since Telodendria's goal is to not
be dependent on any third-party code if at all possible, it makes
sense to have a simple HTTP client to use not only for testing
Telodendria, but also for configuring it. When we move the
configuration to the database, we'll ship a script that uses this
tool to allow admins to easily submit API requests.
Do not be concerned that HttpClient does not support TLS yet. TLS
support is necessary for federation to work, so it is coming
eventually.
