unittests: Use more adequate names for some functions

2017-03-11T23:54:23+00:00

unittests: Do not import libnvim or headers in main process

2017-03-11T20:23:49+00:00

Slows down unit tests much, but gets rid of as much preserved state as possible.

unittests: Check core dumps in after_each, like in functests

2017-03-11T20:23:49+00:00

unittests: Run all unit tests in their own processes

2017-03-11T20:23:30+00:00

Used

    sed -r -i -e '/ helpers =/ s/$/\nlocal itp = helpers.gen_itp(it)/; s/^(\s*)it\(/\1itp(/' test/unit/**/*_spec.lua

to alter all tests. Locally they all run fine now.

Reasoning:

1. General: state from one test should not affect other tests.
2. Local: travis build is failing with something which may be an output of
   garbage collector. This should prevent state of the garbage collector from
   interferring as well.

rbuffer: Reimplement as a ring buffer and decouple from rstream

2015-07-01T08:40:53+00:00

Extract the RBuffer class from rstream.c and reimplement it as a ring buffer,
a more efficient version that doesn't need to relocate memory.

The old rbuffer_read/rbuffer_write interfaces are kept for simple
reading/writing, and the RBUFFER_UNTIL_{FULL,EMPTY} macros are introduced to
hide wrapping logic when more control is required(such as passing the buffer
pointer to a library function that writes directly to the pointer)

Also add a basic infrastructure for writing helper C files that are only
compiled in the unit test library, and use this to write unit tests for RBuffer
which contains some macros that can't be accessed directly by luajit.
