Summary by CodeRabbit

Chores
- CI workflows now use a configurable CONAN_HOME cache location for more consistent caching across environments.
- Conan cache references consolidated to use the new environment-driven path.
- Build dependency updated: gRPC bumped to a newer compatible version.
- Protobuf is referenced in metadata but remains inactive (commented out).
- A previously enforced libmount requirement has been disabled.

📝 Walkthrough

Walkthrough

Adds CONAN_HOME env var to two GitHub Actions workflows and replaces hard-coded Conan cache paths with ${{ env.CONAN_HOME }}; updates conanfile.py to bump grpc from 1.65.0 → 1.67.1, leaves protobuf commented (now protobuf/6.32.1), and comments out the libmount/2.39 override.

Changes

Cohort / File(s)	Summary
Workflows — Conan cache path `.github/workflows/analyzers.yml`, `.github/workflows/ci v2.yml`	Add `CONAN_HOME` env var and replace hard-coded Conan cache paths (`~/.conan2`, `/Users/runner/.conan2/`) with `${{ env.CONAN_HOME }}` in cache steps.
Conan recipe — dependencies `conanfile.py`	Under `with_grpc`: bump `grpc` from `1.65.0` → `1.67.1`; `protobuf` line updated to a commented `protobuf/6.32.1`; `libmount/2.39` override moved to commented (no longer enforced).

Poem

🐰 I hopped through YAML and recipe rows,
CONAN_HOME planted where the cache now grows,
grpc leapt up a bit, protobuf hides out,
libmount paused its march without a shout,
I nibbled a carrot and tinkered with prose 🥕

Title check	❓ Inconclusive	The title 'try fix caching' is vague and generic, using non-descriptive language that lacks specificity about what caching issue is being addressed or how it's being fixed.	Use a more descriptive title such as 'Replace hard-coded Conan cache paths with CONAN_HOME environment variable' to clearly convey the specific caching fix being implemented.

In @.github/workflows/analyzers.yml:
- Around line 10-12: Replace the Conan 1.x env var CONAN_USER_HOME with the
Conan 2 correct variable CONAN_HOME (i.e., set CONAN_HOME: "${{ github.workspace
}}/release/") so the conan cache restore/save steps target the actual Conan 2
cache, and remove the unused CONAN_USER_HOME_SHORT variable (or rename and wire
it up if intended) to avoid dead config; ensure any workflow steps that
referenced CONAN_USER_HOME now reference CONAN_HOME (and update any cache key
names if they relied on the old variable).

In @.github/workflows/ci v2.yml:
- Around line 19-21: The workflow is setting Conan 1.x variables CONAN_USER_HOME
and CONAN_USER_HOME_SHORT which are ignored by Conan 2; replace those env keys
with CONAN_HOME and remove or stop using CONAN_USER_HOME_SHORT, and update every
reference that reads env.CONAN_USER_HOME (e.g., in the cache steps that
reference env.CONAN_USER_HOME) to use env.CONAN_HOME instead so the cache/config
directory aligns with Conan 2; ensure the env block defines CONAN_HOME: "${{
github.workspace }}/release/" (or equivalent) and update any cache restore/save
keys that previously used CONAN_USER_HOME to use CONAN_HOME.

- Around line 47-49: The protobuf requirement conflicts with grpc/1.72.0's
transitive protobuf; update the self.requires entry(s) in conanfile.py to
resolve the conflict by either removing the explicit
self.requires("protobuf/6.32.1") line to allow gRPC's transitive
protobuf/5.27.0, changing it to self.requires("protobuf/5.27.0") to match gRPC,
or keep protobuf/6.32.1 but add override=True on that self.requires call to
force the newer protobuf (accepting potential ABI risk); modify the
self.requires("protobuf/6.32.1") statement accordingly.

🌐 Web query:

grpc 1.72.0 conan center index available

💡 Result:

Yes—grpc/1.72.0 is available on ConanCenter (Conan 2). The ConanCenter recipe page lists grpc/1.72.0 and shows install usage via:

[requires] grpc/1.72.0

It also indicates the recipe revision date as 2025-10-30 and that binaries are available for Linux/Windows/macOS (including Apple Silicon) and Windows ARM64. [1]

Remove or document the commented-out dependency lines.

grpc/1.72.0 is available on ConanCenter. Since with_libsystemd=False disables libsystemd support in grpc (line 27), the libmount/2.39 override is no longer needed and can be safely removed. The commented-out protobuf/6.32.1 line aligns with letting grpc pull protobuf transitively.

Either remove these commented lines entirely or add a brief comment explaining why they're kept (e.g., "/* Protobuf pulled by grpc transitively */") to avoid confusion for future maintainers.
