Summary:
Is_ancestor was inexplicably slow so I added a few perf counters to it. The slowness should be fixed with D14540318.
This will only add the most important perf counters as I have seen some slow down when adding more.
I also changed the param naming from maybe_ancestor to ancestor. The maybe is implied through the method name being is_ancestor. This change also brings skiplist in line with apiserver
What will we log:
Ancestor/Descendant Generation
skip/noskip iterations
skipped generations

Mononoke is a next-generation server for the Mercurial source control
system, meant to scale up to accepting
thousands of commits every hour across millions of files. It is primarily
written in the Rust programming language.
Caveat Emptor
Mononoke is still in early stages of development. We are making it available now because we plan to
start making references to it from our other open source projects such as
Eden.
The version that we provide on GitHub does not build yet.
This is because the code is exported verbatim from an internal repository at Facebook, and
not all of the scaffolding from our internal repository can be easily extracted. The key areas
where we need to shore things up are:
Full support for a standard cargo build.
Open source replacements for Facebook-internal services (blob store, logging etc).
The current goal is to get Mononoke working on Linux. Other Unix-like OSes may
be supported in the future.
