[PR] chore(deps): Bump aws-lc-sys to 0.44.0 to fix jitterentropy build under conda-forge [sedona-db]
jiayuasu opened a new pull request, #1185:
URL: https://github.com/apache/sedona-db/pull/1185
## What
`cargo update -p aws-lc-rs` — moves `aws-lc-rs 1.15.2 → 1.18.0` and `aws-lc-sys 0.35.0 → 0.44.0` in `Cargo.lock`. Nothing else changes.
## Why
The conda-forge 0.4.1 builds (conda-forge/sedonadb-feedstock#14) fail on every Linux and macOS job while compiling `aws-lc-sys 0.35.0`:
```
jitterentropy-base.c:47:3: error: "The CPU Jitter random number generator must not be compiled with optimizations. See documentation. Use the compiler switch -O0 for compiling jitterentropy.c."
```
The same recipe built 0.4.0 fine eight days earlier; the difference is in our lockfile, where `cc` went from 1.2.51 (0.4.0) to 1.4.0 (0.4.1).
`aws-lc-sys 0.35` forces `-O0` for jitterentropy by temporarily appending it to `CFLAGS_<target>`, calling `cc::Build::get_compiler()`, then restoring the variable. That only worked because `cc <= 1.2.51` cached env lookups. Newer `cc` re-reads the env when it actually compiles, so the restored conda `CFLAGS` (`-O2`) get appended after `-O0` and win. conda-forge's rust activation exports `CFLAGS_<target>="${CFLAGS}"`, which is why it bites there and not in our own CI.
`aws-lc-sys >= 0.40` fixes this properly: it holds the override for the whole compile and strips any `-O*` from the inherited CFLAGS.
## Verification
Reproduced with a minimal crate and with this workspace's lockfile: `cargo build --locked --release -p aws-lc-sys` with `CFLAGS="-O2 -fPIC"` and `CFLAGS_<target>="-O2 -fPIC"`:
| lock | result |
|---|---|
| aws-lc-sys 0.35.0 + cc 1.4.0 (before) | fails with the `#error` above |
| aws-lc-sys 0.44.0 + cc 1.4.0 (this PR) | builds |
The feedstock carries a temporary `cargo update -p aws-lc-rs --precise 1.18.0` in its build script to unblock 0.4.1; it can be dropped once a release ships with this lockfile.
