Maintainers are most responsive around 16:00 UTC (16:00 UTC in your timezone). Recommended submission window is Monday - Wednesday from 15:00 to 19:00 UTC (15:00 - 19:00 UTC local).
Maintainer Strategy: Maintainer Sweet Spot: PRs under 150 lines merge in ~30 hours (88% approval). Large PRs (>500 lines) take ~223 hours (32% approval). Keep your diff compact for rapid review.
When a project command ran with cot command fails because of invalid arguments, the usage line shows the project's binary name instead of cot. For example, in a project whose binary is m4txblog: ❯ cot collect-static error: the following required arguments were not provided: <dir> Usage: m4txblog collect-static <dir> For more information, try '--help'. However, --help correctly shows cot: ❯ cot collect-static --help Collects all static files into a static directory Usage: cot collect-static <dir> Arguments: <dir> The directory to collect the static files into Options: -h, --help Print help Ideally, the error output should also use cot as the binary name, since that is the command the user actually ran. See #666 (comment) for more info
There are some doctests that copy-paste the same structs or migrations over and over again (see #675 for an example). It would be nice to review what we have, and extract the common code out of these tests. It should go either to some doc(hidden) part in the cot crate, or (preferably) into another crate, e.g. cot-test.
At least wherever the code is a part of a public API (i.e. not tests), we should consider using core::future::ready instead of bypassing the clippy lint for a tiny overhead reduction. See: https://rust-lang.github.io/rust-clippy/master/?search=unused_async_trait_impl#unused_async_trait_impl
In Rust, it's idiomatic for the error messages to start with lowercase letters and NOT end with a dot (unless there are multiple sentences in a message). We follow this rule in most of the places, but not everywhere. We should clean this up and make sure all the error messages are written in an idiomatic and, most importantly, consistent way. It might be good to mention this in CONTRIBUTING.md as well.
Problem statement The set of middlewares that we have enabled by default keeps growing (the latest one is #633). Eventually, the project template/boilerplate code will grow a lot. Proposed solution Let's create a "CommonMiddleware" (akin to Django's CommonMiddleware) that just consolidates the enabled-by-default middlewares. We should also have a flag in config.toml that allows to enable or disable each child middleware from CommonMiddleware.
