Summary: We can hit a deadlock during getfiles requests. We first send all requests via stdin, and then read the output via stdout. The problem is that any of the buffers anywhere between hg and mononoke may fill up, and the whole process deadlocks. Unfortunately there is no good solution yet. For now let's make the buffer in hgcli big enough to make sure it won't be a problem. Let's bump it to 400Mb. Note that the buffer will be allocated on demand in the channel. So it won't use too much memory. Reviewed By: sunshowers Differential Revision: D8195511 fbshipit-source-id: bd97509bd26f8cea7d41e44933e02bd0bc2c76c4 |

Mononoke
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.
