Doc builds on readthedocsc.org were still failing because of the missing
`build.os` key. Update the config to conform with the recommendations
from https://docs.readthedocs.io/en/stable/config-file/v2.html

Move docs build instructions out of README.md

See merge request !83

Documenting the documentation, fix ReadTheDocs

See merge request !81

Add DoH configs with eclusively GET/POST methods

See merge request !82

It can be useful to test GET and POST methods of DNS-over-HTTPS
exclusively, add a couple of standard configs to handle these scenarios.

Use CMake to build dnssim

See merge request !77

Replaces GNU Autotools with CMake, which seems to be taking over the
world of building C projects.

As for dnssim, this makes it (in my opinion) slightly easier to
maintain, as Autotools tend to be quite clunky when settings change,
which is quite often the case when introducing new libraries (like
ngtcp2 for QUIC - !75).

It will also make it kind of easier to use Git submodules for some
dependencies (again handy for ngtcp2, which is not yet stable).

extra-clients: warn if some input packets were skipped

See merge request !80

plot-packet-rate: trim chart whitespace

See merge request !79

Petr Špaček authored 1 year ago and Oto Šťáva committed 1 year ago

Default X-axis sizing almost always generated white space on the right
side.

plot-latency: use fractional values for humans in charts

See merge request !78

The previously used %s format sometimes led to axis descriptions like
0.099999999 and the like. The new format specifier %g rounds more
sensibly to 0.1.

Add --preload argument for debugging

See merge request !76

The value gets prepended to the LD_PRELOAD envirnoment variable for
`shotgun.lua`. This is useful e.g. for debugging with AddressSanitizer,
where `libasan.so` needs to be the first preloaded library, but
preloading it to the Python script generates an immense amount of noise.

Remove hardcoded plot styles

Closes #27

See merge request !65

generate-const-qps: tool to generate constant QPS

See merge request !33

filter-dnsq: ability to log malformed queries

See merge request !72

It helps to determine where to look in the packet.

plot-response-rate: ability to ignore RCODEs with small response rate

See merge request !73

This is more important for long test where filtering based on total
number of answers (-R option) is too smoothed out and is missing spikes.

plot-packet-rate: handle incomplete last sampling period

See merge request !71

plot-response-rate: estimate wost case drop caused by discarded packets

See merge request !74

Usable ONLY as sanity check, does not have any value for real benchmarking.

More often than not, the last sampling period in CSV is incomplete and
that used to cause the plotter to not print sampling period in the
chart, rendering the field useless.

Ignore the change in the sampling period if it happened on the very last
sample and use preceding (constant) period value in generated chart.

Nits: minor fixes

See merge request !70

Fix a typo from "DNS-over-TLS POST" to "DNS-over-HTTPS POST"

Add generated .libs directory into .gitignore

Change linestyle in latency charts

See merge request !69

It makes pylint happy (and the code more readable, in this case).
