Harden the code that does permission checks to protect against
re-opening of stdin.
Code that runs FFI is vulnerable to an attack where fd 0 is closed
during a permission check and re-opened with a file that contains a
positive response (ie: `y` or `A`). While FFI code is dangerous in
general, we can make it more difficult for FFI-enabled code to bypass
additional permission checks.
- Checks to see if the underlying file for stdin has changed from the
start to the end of the permission check (detects races)
- Checks to see if the message is excessively long (lowering the window
for races)
- Checks to see if stdin and stderr are still terminals at the end of
the function (making races more difficult)
Fixes #20516
Follow up to #21747 and #21746
This tackles the last point of #20516 where certain inputs weren't
accepted in the other zlib methods
This adds the `toU8` conversion of `_brotli` to `_zlib.mjs`, when we
create the ZLibBuffer, we'll sanitize the input. I noticed that the
async had no handler for `string` input so I added that as well.
Fixes https://github.com/denoland/deno/issues/21734
Changes:
- Use default encode when options do not provide a encode callback.
- Remove internal TS for `node:querystring`. Its not helping catching
bugs like this because of invalid type assumptions and use of `any`,
more of a maintenance burden.
This fixes point 3 of https://github.com/denoland/deno/issues/20516
This PR creates consistency between the sync and async versions of the
brotli compress where we will always return a buffer like Node.
This fixes point 2 of #20516
This adds a conversion from Dataview/Buffer by returning `obj.buffer`
which can be converted to a `UInt8Array`.
Question: Regarding point 4 of the mentioned issue would it be
appropriate to copy the toU8 helper to the `zlib.mjs` methods?
These tests started failing on CI on Dec 28th, 2023 returning
ENOTFOUND. It's unclear what's going on, since `dig -x
8.8.8.8.in-addr.arpa`.
It needs a deeper investigation, but I want to unblock main branch
in the meantime.
Main change is that:
- "hyper" has been renamed to "hyper_v014" to signal that it's legacy
- "hyper1" has been renamed to "hyper" and should be the default
`opAsync` requires a lookup by name on each async call. This is a
mechanical translation of all opAsync calls to ensureFastOps.
The `opAsync` API on Deno.core will be removed at a later time.
When we migrate to op-import-per-extension, we will want to ensure that
ops have one and only one place where they are imported. This tackles
the ops that are imported via `ensureFastOps`, but does not yet tackle
direct `ops` imports.
Landing ahead of https://github.com/denoland/deno_core/pull/393
Node HTTP/2 was using the default h2 `Bytes` datatype when we can be
making using of `BufView` like we do in `Deno.serve`.
`fetch` and `Deno.serverHttp` can't make use of `BufView` because they
are using `reqwest` which is stuck on hyper 0.x at this time.
This commit adds a way to connect to the TS compiler host that is run
as part of the "deno lsp" subcommand. This can be done by specifying
"DENO_LSP_INSPECTOR" variable.
