Free the unused Android SDK and .NET before the compiler cache is written - #645
Conversation
Reviewer's GuideThe PR prevents compiler-cache saves from exhausting Linux runner disks by deleting unused Android and .NET installations before cache restores/saves, and adds a contract test that enforces the cleanup's presence, Linux guard, required paths, and ordering across all compiler-cache writers.

Full details: Module-Level Documentation
-
Explanation
Pass this check. The new module
tests/test_ci_free_disk.pyhas a module docstring that states its purpose as a contract test, explains its utility for preventing compiler-cache disk failures, and identifies its relationship to cache-writing Linux jobs. No other Python module changes lack module-level documentation.
Full details: Testing (Unit And Behavioural)
-
Explanation
Pass the testing check.
tests/test_ci_free_disk.py:82-114covers valid recursive removals and rejects printed, inspected, commented, non-recursive, and split-path commands.tests/test_ci_free_disk.py:117-146reads the declared workflow jobs and checks the cleanup count, command, Linux guard, exact directories, and ordering before cache use. This exercises the workflow contract boundary rather than only testing an internal helper. Existing cache-ownership coverage also verifies thatCACHE_WRITERSmatches actual save steps (tests/test_ci_cache_ownership.py:162-180).
Full details: Testing (Property / Proof)
-
Explanation
PASS — Property testing is not required. The new contract checks a finite set of five declared compiler-cache writers with pytest parameterization (
tests/test_ci_free_disk.py:117-146). The shell recognizer uses a small, explicit table of eight meaningful positive and negative command cases (tests/test_ci_free_disk.py:82-114). The cleanup ordering and Linux-guard requirements are also directly auditable from the parameterized workflow contract. No introduced invariant spans enough meaningful inputs to require Hypothesis or another property-testing framework.
Full details: Testing (Compile-Time / Ui)
-
Explanation
Pass this check. The pull request changes YAML workflows, Markdown, and Python contract tests; it introduces no Rust or TypeScript compile-time behaviour, so no trybuild-equivalent test is required. The structured workflow contract is covered with focused semantic assertions and parametrized positive and negative shell-command cases in
tests/test_ci_free_disk.py:82-146, rather than a brittle whole-file snapshot. No text or UI output requires snapshot coverage.
Full details: Unit Architecture
-
Explanation
Pass. The change adds only explicit CI side-effects and contract tests. The cleanup is visible as a named workflow step with a Linux guard,
sudo rm -rf, strict shell handling, and explicit paths. The new test reads workflow declarations through the existing fallible loader and asserts the cleanup command and ordering. It does not add query APIs, hidden state, network calls, clocks, or application dependencies. The fixed filesystem paths are deliberate CI policy at the workflow boundary, not hidden dependencies in a domain unit.
Full details: Domain Architecture
-
Explanation
Pass this check. The pull request changes only GitHub workflow steps, a workflow contract test, and developer documentation. It does not change domain logic, adapters, persistence, transport, or public application code. The cleanup remains infrastructure-scoped and is guarded within the workflows.
Full details: Observability
-
Explanation
Accept the observability coverage. The changed cleanup steps in
.github/workflows/ci.ymland.github/workflows/loom.ymlreport filesystem usage before and after removal withdf -m /(for example,.github/workflows/ci.yml:104-111and.github/workflows/ci.yml:1686-1694).set -euo pipefailmakessudoorrmfailures visible at the failure boundary. Existing cache observation summaries report cache keys and hit states, and the existing resource sampler records disk peaks for sampled jobs. The change adds no secrets, high-cardinality labels, tracing requirement, or new alert requirement.

…tten A version bump misses every Rust sccache entry, so the archive grows to about 3 GiB and no longer fits in the 2 GB left on ubicloud-standard-2. Free the two preinstalled toolchains in every job that saves a compiler cache, and add a contract that holds each such job to it.
Parse cleanup commands as shell invocations so workflow contracts reject mere path mentions that do not recursively remove both directories. Document the cleanup steps and cache-writer conditions for maintainers.

Sorry, something went wrong.
Split recursive-option recognition and argument parsing into focused helpers. This keeps the workflow contract test readable and below the CodeScene complexity threshold.

Problem
lint-testhas failed on every push tomainsince run 38987616012, at "Save the compiler cache" withNo space left on device. Pull-request runs never save, so they stayed green.Cause: the 0.2.0-beta2 version bump (#634) misses every Rust sccache entry (Rust hit rate 98.55% on the last green run, 0.10% after). The restored 1.83 GB cache grows to 3 GiB, and its archive does not fit in the 2.1 GB left on the 73 GB volume. A trial with the versions reverted gave 97.2% Rust hits (run 39180974237). Every version bump will repeat this.
