backout: remove
db9b6ce803a9
That changeset lost its topic for unknown reason and ended up being picked by
some automation. So I backout it previous incarnation until it can get properly
reviewed.
infinitepush: aggressively deprecated infinite push
We add a large warning and an explicit abort. Both can be disable through
config, but neither are explicitly documented. If any user exists I really want
them to get in touch with the community.
rust-dependencies: switch from `users` to `whoami`
`users` is unmaintained, with the maintainer apparently MIA. `whoami` is a
popular crate that does simple wrapping of platform-specific calls.
This makes the overhead from using `blackbox` lower. It used to be up 10ms
on slower hardware for both calls, now down to <1ms which is always good.
rust-hg-core: move from `ouroboros` to `self_cell`
`ouroboros` has a fundamental soundness problem that, while not applicable
today, could become applicable given new compiler optimizations.ยน
`self_cell` is a crate that accomplishes a lot of the same things that
`ouroboros` did while remaining sound (that is, unless a new soundness issue
is discovered) by not assuming as much about the memory layout of the program.
`self_cell` has been scrutinized heavily in the past few months by very
competent people, some from the compiler team and has shown no weaknesses
for a while, with a 1.0 stable release coming out a couple months ago.
Our internal API is exactly the same, this is just an implementation detail.
To reiterate, no actual soundness issue was found with our use of `ouroboros`,
but there might be evolutions of `rustc` (or even a future separate compiler)
that could generate unsound code.

debug-revlog-stats: make it use the new store entry API
This give use free tree manifest support in the process.
