From 74206d80680071b0c11d99598f47b1d7e11b7093 Mon Sep 17 00:00:00 2001 From: James Devine Date: Fri, 5 Jun 2026 22:28:21 +0100 Subject: [PATCH 2/5] 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).

Skip the append when az is missing so the agent never tries to call az on a runner that doesn't have it. Design ====== AzureCliExtension::prepare_steps() now returns TWO YAML steps: 1. Detection (existing) — sets AW_AZ_MOUNTS to the two --mount args or empty string. 2. NEW: "Append Azure CLI prompt" — a single-quoted heredoc that cats an Azure CLI advisory into /tmp/awf-tools/agent-prompt.md, gated by `condition: ne(variables['AW_AZ_MOUNTS'], '')`. The CompilerExtension trait API is unchanged. wrap_prompt_append is unchanged. The single call site in common.rs:2311 is unchanged. prompt_supplement() on AzureCli stays None. The conditional injection is entirely self-contained inside the extension's own prepare_steps Vec. Why not extend the trait. The existing prompt_supplement() hook doesn't carry a step-level condition. Adding one would require a new trait method, a new wrap_prompt_append signature, an enum-macro arm update, and a call-site change in common.rs — disproportionate for a 15-line advisory that only one extension wants gated. Advisory content ================ The advisory assumes az IS available (no "may be" hedging — the step only runs when it is) and covers: - az devops family — autoauthed via $AZURE_DEVOPS_EXT_PAT when permissions: read: is declared - Azure Resource Manager — separate identity required, not provisioned by ado-aw - Microsoft Graph — same caveat as ARM - Fallback — file a missing-tool safe output naming azure-cli Heredoc terminator is SINGLE-QUOTED ('AZURE_CLI_PROMPT_EOF') so $AZURE_DEVOPS_EXT_PAT and similar literals are appended verbatim rather than being shell-expanded to the runner's PAT value. Locked in by test_azure_cli_prompt_append_uses_single_quoted_heredoc. Tests ===== Five new unit tests in src/compile/extensions/azure_cli.rs: - test_azure_cli_prompt_append_step_is_conditional - test_azure_cli_prompt_append_step_targets_agent_prompt_file - test_azure_cli_prompt_append_step_has_advisory_anchors - test_azure_cli_prompt_append_uses_single_quoted_heredoc - test_azure_cli_prompt_append_displayname_matches_lint_list Existing test_azure_cli_prepare_steps_detects_az_before_setting_var updated for the new vec length (2 instead of 1). Integration test test_default_pipeline_mounts_az_and_allows_azure_hosts extended to assert the displayName, the condition expression in the same step (proximity check), and the advisory anchor strings. tests/bash_lint_tests.rs REQUIRED_STEP_DISPLAY_NAMES gains "Append Azure CLI prompt" so shellcheck exercises the new heredoc. tests/safe-outputs/azure-cli.lock.yml regenerated. Docs ==== docs/network.md and docs/tools.md "Always-on Azure CLI" sections gain a paragraph describing the conditional advisory injection. The same edits also correct a small carryover inaccuracy from commit 7fe562f: the previous text said "leaves AW_AZ_MOUNTS unset" — the graceful-degradation fix actually sets it to the empty string. Now documented correctly with the rationale.

Word splitting of the expanded value into separate `--mount` tokens is intentional and required (the pipeline variable expands to `--mount /opt/az:/opt/az:ro --mount /usr/bin/az:/usr/bin/az:ro` or to the empty string). Quoting would produce a single malformed token. Disable SC2046 with an inline directive on the `sudo -E` line in all four base templates (base, 1es-base, job-base, stage-base) so the directive applies to the multi-line awf invocation as a unit. Regenerated tests/safe-outputs/azure-cli.lock.yml; verified bash_lint_tests passes locally with shellcheck 0.11.0.
