Problem:
Node implements fs.readFile as:
- a call to stat, then
- a C++ -> libuv request to read the entire file using the stat size
Why is this bad?
The effect is to place on the libuv threadpool a potentially-large
read request, occupying the libuv thread until it completes.
While readFile certainly requires buffering the entire file contents,
it can partition the read into smaller buffers
(as is done on other read paths)
along the way to avoid threadpool exhaustion.
If the file is relatively large or stored on a slow medium, reading
the entire file in one shot seems particularly harmful,
and presents a possible DoS vector.
Solution:
Partition the read into multiple smaller requests.
Considerations:
1. Correctness
I don't think partitioning the read like this raises
any additional risk of read-write races on the FS.
If the application is concurrently readFile'ing and modifying the file,
it will already see funny behavior. Though libuv uses preadv where
available, this doesn't guarantee read atomicity in the presence of
concurrent writes.
2. Performance
Downside: Partitioning means that a single large readFile will
require into many "out and back" requests to libuv,
introducing overhead.
Upside: In between each "out and back", other work pending on the
threadpool can take a turn.
In short, although partitioning will slow down a large request,
it will lead to better throughput if the threadpool is handling
more than one type of request.

This commit renames the user defined variables to lowercase to follow

currently if you want to use dynamic import you must use both the

Chrome is currently shipping dynamic import unflagged, the flag
only remains in V8 to guard embedders who have not set the appropriate
callback from throwing an unhandled rejection when the feature is used.
As such it is reasonable to enable the flag by default for
`--experimental-modules`
