chore: fix spelling
|
|
Normally a single spell checker can't find all the mistakes or check all types of code.
These mistakes were found by another spell checker inside my editor with a more manual sift / find.

Official -> "The individual jobs in a workflow can interact with (and compromise) other jobs. For example, a job querying the environment variables used by a later job, writing files to a shared directory that a later job processes, or even more directly by interacting with the Docker socket and inspecting other running containers and executing commands in them.
This means that a compromise of a single action within a workflow can be very significant, as that compromised action would have access to all secrets configured on your repository, and can use the GITHUB_TOKEN to write to the repository. Consequently, there is significant risk in sourcing actions from third-party repositories on GitHub. "

It used to return `mrb_ssize` but its size may differ from `mrb_int`,
e.g. `MRB_INT64` on `MRB_32BIT` architecture.

shuujii/avoid-possibility-of-reading-uninitialized-areas-in-h_check_modified
Avoid possibility of reading uninitialized areas in `h_check_modified()`
|
|
In `h_check_modified()`, in the case of `MRB_NO_BOXING`, `ht_ea()` or
`ht_ea_capa()` for AR may read uninitialized area. Therefore, do not use
those macros for AR in `MRB_NO_BOXING` (but in the case of `MRB_64BIT`,
`ht_ea_capa()` is the same as `ar_ea_capa()`, so use it).
fix #5332

Binary gems description added, along with a few cosmetic changes.
|
|
Binary gems are mrbgems that set `spec.bins` in their `mrbgem.rake`,
and usually their names are prefixed with `mruby-bin-`.
|
|
Especially description regarding the build process and `build` directory
structures, along with some typo fixes and cosmetic changes.
