mptcpanalyzer's Issues

highlevel TODO list

to reach feature parity with mptcpanalyzer:

upstream our changes to optparse-applicative

We had to fork optparse-applicative to provide live completion (vs the currently static bash/zsh generated ones) at https://github.com/teto/optparse-applicative/

This is quite annoying from a distribution perspective so let's try upstreaming those changes.

cold build are excessively long (~10 minutes).
I had a good experience with https://github.com/codedownio/time-ghc-modules showing that the Template Haskell code is the worrying bit. It would be worth investigating deeper to have better results.

sharkd support

I've spent some time investigating the use of sharkd (see https://teto.github.io/posts/2021-12-02-sharkd-introduction.html) to avoid some computation in mptcpanalyzer but the protocol is particularly brittle see
https://ask.wireshark.org/question/25581/invalid-json-request-to-tshark/
https://gitlab.com/wireshark/wireshark/-/issues/17824

An occasion to test rust ? :)

support ghc 9.2

depends on

kowainik/colourista#75 (for co-log-core)
JonasDuregard/sized-functors#9
byteverse/contiguous#46 (waiting on release)
mightybyte/readable#2
frames acowley/Frames#163
haskell-chart
byteverse/byteslice#17

capability to create new subflows

it is possible to create new subflows with the fork, but it is harder to do on upstream for now see
multipath-tcp/mptcp_net-next#186

fix documentation on hackage

doc for https://hackage.haskell.org/package/mptcp-pm was not generated because of a cabal issue (check the build log at the bottom left).
Let's make sure we can build the project both via cabal and nix (or maybe hackage doesn't use/see the cabal.project ? to check).

plot statistics in realtime

mptcpanalyzer is capable of computing stats on the fly and display them in CLI but would be nice to plot some statistics in realtime. Looks possible with the current backend:
timbod7/haskell-chart#226

enable caching

to enable caching, we need to:

be able to generate a hash from a CacheEntry
When writing to cache we have:
Nothing | Nothing | Just 0 | Just 4093186044
we need special write instances so that we can use the same loading procedure from csv etc
