From 74206d80680071b0c11d99598f47b1d7e11b7093 Mon Sep 17 00:00:00 2001 From: James Devine Date: Fri, 5 Jun 2026 22:28:21 +0100 Subject: [PATCH 2/3] refactor(compile): detect az at pipeline time so missing azure-cli no longer crashes 1ES Reviewer-requested fix: static AWF bind-mounts for /opt/az and /usr/bin/az would break `docker run` on runners without azure-cli pre-installed (notably some 1ES self-hosted pools), failing the pipeline before the agent ever started. Replace the static mounts with a runtime detection prepare step that sets the ADO pipeline variable AW_AZ_MOUNTS via `##vso[task.setvariable]` when both /usr/bin/az and /opt/az exist on the host, or emits a `task.logissue` warning and leaves the variable unset otherwise. The AWF invocation in the compiled YAML now includes a single `$(AW_AZ_MOUNTS) \` line in the --mount chain. ADO interpolates the variable at step start: present -> the two --mount args appear; absent -> the line collapses to whitespace.

CRITICAL — AW_AZ_MOUNTS undefined when az is missing: The runtime-detection step in AzureCliExtension only set the AW_AZ_MOUNTS pipeline variable in the detected branch. In the missing-az branch the variable was left undefined. ADO leaves an undefined $(VAR) as the LITERAL STRING "$(VAR)" in subsequent bash steps (it does NOT expand to empty). Bash sees $(AW_AZ_MOUNTS), interprets it as a $(...) command substitution, tries to execute a program named AW_AZ_MOUNTS, gets exit 127, and the AWF invocation step dies under `set -e` — the exact 1ES failure mode the refactor set out to prevent. Fix: always emit `##vso[task.setvariable variable=AW_AZ_MOUNTS]`, with an empty value in the missing branch. ADO then expands $(AW_AZ_MOUNTS) to nothing and the trailing `\` line becomes a harmless continuation no-op. Regression guards (both lock this in): - azure_cli.rs::test_azure_cli_prepare_steps_defines_aw_az_mounts_in_else_branch counts `setvariable` occurrences (must be 2) and asserts the else block contains an empty-value setvariable line. - compiler_tests.rs::test_default_pipeline_mounts_az_and_allows_azure_hosts asserts the same 2× count on the compiled lock.yml. 2. Cleanup — delete WRITE_REQUIRING_SAFE_OUTPUTS: The const was retained with #[allow(dead_code)] after the removal of `validate_write_permissions`, but its only consumers left were the two tests that exercised the const itself. Each `*Result` type already carries `REQUIRES_WRITE: bool` for any caller (compiler, audit, runtime) that needs the same info. Deleting the const removes a dead-code annotation and one otherwise-purposeless list to maintain when adding new tools. Test cleanup: removed `test_write_requiring_subset_of_all_known` (purely exercised the deleted const) and rewrote `test_all_known_completeness` to use a HashSet-based duplicate check on ALL_KNOWN_SAFE_OUTPUTS plus the ALWAYS_ON/NON_MCP disjointness check (preserves the meaningful invariants).
