From b14064814794e02012d4ee79133617de100b627f Mon Sep 17 00:00:00 2001 From: Yuliia Kovalova Date: Thu, 16 Jul 2026 11:06:55 +0200 Subject: [PATCH 01/20] Build Failure Analysis: reuse Azure DevOps binlogs instead of rebuilding MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Reworks both build-failure-analysis workflows so they no longer run `./build.sh`. testfx's authoritative PR build runs on Azure DevOps (dnceng-public/public, pipeline "microsoft.testfx", definitionId 209) and publishes each build leg's binary log as a `Logs_Build_` pipeline artifact. The workflows now download those already-produced binlogs and analyze them — no duplicate build, and no fork-PR code execution (we only download artifacts, never check out or run PR code). - Auto workflow: trigger changed from `pull_request` (self-build) to `check_run: completed`; the fetch-binlog job filters to the `microsoft.testfx` check reporting failure, resolves the ADO build id from the check details URL, and downloads every `Logs_Build_*` binlog anonymously (public project). PR number comes from the check payload with a commits->PR fallback for fork PRs. Scoped to PRs targeting main / rel/*. - Command workflow (`/analyze-build-failure`): finds the PR's most recent failed `microsoft.testfx` build (refs/pull//merge) and downloads its binlogs. Same base-branch scope. - All build legs are fetched into a directory mounted at /data/binlogs; the agent triages every leg via GH_AW_BINLOG_LIST and focuses on the one(s) with errors (test-only failures leave build binlogs clean -> it says so rather than inventing fixes). - check_run has no native PR context in gh-aw, so safe-outputs use `target: "*"` and the agent posts to the resolved GH_AW_PR_NUMBER. - Also folds in the agent-doc fixes from #9982 (NuGet.Mcp.Server invocation, inline-suggestion cap 25, no hard-coded model, raw HTML marker).

From cc45973f4fd2f3d068581df44a785723882dad0b Mon Sep 17 00:00:00 2001 From: Yuliia Kovalova Date: Thu, 16 Jul 2026 11:50:42 +0200 Subject: [PATCH 02/20] Address review: multi-binlog propagation, PR-source reads, build/PR validation - Shared body + agent doc: finish the multi-leg migration. The delegation prompt now forwards GH_AW_BINLOG_LIST / GH_AW_BINLOG_DIR and instructs the sub-agent to query every leg's binlog (not just the first); the obsolete "/data/build.binlog" single-file mount wording is replaced with the /data/binlogs directory model. - Agent doc: the workspace is NOT a checkout of the failing PR (check_run / slash command / dispatch run on the default branch), so read PR source through the GitHub API at GH_AW_PR_HEAD_SHA rather than GH_AW_WORKSPACE. - Auto workflow (dispatch): validate the supplied build is definition 209 AND its sourceBranch is refs/pull//merge (plus result=failed) before analyzing, so a build-id/PR mismatch can't post to the wrong PR. - Command workflow: select the PR's latest *completed* build and require its result to be `failed`, so a PR that has since gone green (or been force-pushed to passing) is not re-analyzed with a stale binlog.

Artifacts come from PR builds and are untrusted. (both workflows) - Auto workflow: set `roles: all` so advisory analysis runs for every failing PR — including external contributors' PRs. gh-aw's default author gate would otherwise skip them, and on `check_run` the actor is the pipeline app anyway. Safe: read-only binlog + advisory comments, no PR code execution. - Delegation: launch the sub-agent with `agent_type: "build-failure-analyst"` so the custom agent definition is loaded (was `general-purpose`). - Docs: clarify the workspace may or may not be a PR checkout depending on trigger; the GitHub API at GH_AW_PR_HEAD_SHA is the source of truth.

Depending on the trigger the runner workspace may not be a checkout of the failing PR (the `check_run` / dispatch paths run on the default branch or an unrelated ref), so treat the **GitHub API / `github` MCP tool at the `GH_AW_PR_HEAD_SHA` ref** as the source of truth for PR source (convert the absolute compiler paths in the binlog to repo-relative paths first) rather than reading the local workspace. - For Roslyn / C# errors: read 6 lines above and 10 lines below the reported line. - For MSBuild errors: read the offending element and the surrounding `` / `` / ``. diff --git a/.github/workflows/build-failure-analysis-command.lock.yml b/.github/workflows/build-failure-analysis-command.lock.yml index 5eafd81269..ab1a4c55a3 100644 --- a/.github/workflows/build-failure-analysis-command.lock.yml +++ b/.github/workflows/build-failure-analysis-command.lock.yml @@ -1,4 +1,4 @@ -# gh-aw-metadata: {"schema_version":"v4","frontmatter_hash":"b09eced8d1dc5a64fd8565fa3b80aca7bbcaadcd72d39de4edbeb612eb0a4402","body_hash":"f87d482e0c91223a7ebee376668245e3515f8d5666477a94fb4ae0d9562ec099","compiler_version":"v0.82.8","strict":true,"agent_id":"copilot","engine_versions":{"copilot":"1.0.68"}} +# gh-aw-metadata: {"schema_version":"v4","frontmatter_hash":"de43efe6704f932cc83240390fba3d2a3a8f59e7f78cf21fbb860ceb59a97e72","body_hash":"476a956c3e9739a9c95cec76064b0b8c484ee768e023b594e0a5fa08865c1aac","compiler_version":"v0.82.8","strict":true,"agent_id":"copilot","engine_versions":{"copilot":"1.0.68"}} # gh-aw-manifest: {"version":1,"secrets":["COPILOT_GITHUB_TOKEN","GH_AW_GITHUB_MCP_SERVER_TOKEN","GH_AW_GITHUB_TOKEN","GITHUB_TOKEN"],"actions":[{"repo":"actions/cache/restore","sha":"55cc8345863c7cc4c66a329aec7e433d2d1c52a9","version":"v6.1.0"},{"repo":"actions/cache/save","sha":"55cc8345863c7cc4c66a329aec7e433d2d1c52a9","version":"v6.1.0"},{"repo":"actions/checkout","sha":"9c091bb21b7c1c1d1991bb908d89e4e9dddfe3e0","version":"v7.0.0"},{"repo":"actions/download-artifact","sha":"3e5f45b2cfb9172054b4087a40e8e0b5a5461e7c","version":"v8.0.1"},{"repo":"actions/github-script","sha":"3a2844b7e9c422d3c10d287c895573f7108da1b3","version":"v9.0.0"},{"repo":"actions/setup-dotnet","sha":"26b0ec14cb23fa6904739307f278c14f94c95bf1","version":"v5.4.0"},{"repo":"actions/setup-node","sha":"48b55a011bda9f5d6aeb4c2d9c7362e8dae4041e","version":"v6.4.0"},{"repo":"actions/upload-artifact","sha":"043fb46d1a93c77aae656e7c1c64a875d1fc6a0a","version":"v7.0.1"},{"repo":"github/gh-aw-actions/setup","sha":"99d9d888952ee25fce70c6b3120ca490d7d8da95","version":"v0.82.8"}],"containers":[{"image":"ghcr.io/github/gh-aw-firewall/agent:0.27.29","digest":"sha256:debc0b18ef8ea3a64585c4d1eea1099f0d9fa76b53d34a1f3c53b3225fe158fe","pinned_image":"ghcr.io/github/gh-aw-firewall/agent:0.27.29@sha256:debc0b18ef8ea3a64585c4d1eea1099f0d9fa76b53d34a1f3c53b3225fe158fe"},{"image":"ghcr.io/github/gh-aw-firewall/api-proxy:0.27.29","digest":"sha256:c7754df3f06f346c817db0525ba523cbdaf5349239fd7f37897c4250a8fc7bde","pinned_image":"ghcr.io/github/gh-aw-firewall/api-proxy:0.27.29@sha256:c7754df3f06f346c817db0525ba523cbdaf5349239fd7f37897c4250a8fc7bde"},{"image":"ghcr.io/github/gh-aw-firewall/squid:0.27.29","digest":"sha256:7bfa0742f9a5bd6309507caaa80a8b6cf3e05bd95a1429affbf64cc94cfbd34f","pinned_image":"ghcr.io/github/gh-aw-firewall/squid:0.27.29@sha256:7bfa0742f9a5bd6309507caaa80a8b6cf3e05bd95a1429affbf64cc94cfbd34f"},{"image":"ghcr.io/github/gh-aw-mcpg:v0.4.1","digest":"sha256:ad2a979c2cd8b50098e84938ca9c9c1580eb8e91526f101a90adfba7859b2c32","pinned_image":"ghcr.io/github/gh-aw-mcpg:v0.4.1@sha256:ad2a979c2cd8b50098e84938ca9c9c1580eb8e91526f101a90adfba7859b2c32"},{"image":"ghcr.io/github/gh-aw-node","digest":"sha256:529d02eb970b1161aa25c593a9c3df57fdfad5a8add328cb3b6eccef66f3183b","pinned_image":"ghcr.io/github/gh-aw-node@sha256:529d02eb970b1161aa25c593a9c3df57fdfad5a8add328cb3b6eccef66f3183b"},{"image":"ghcr.io/github/github-mcp-server:v1.5.0","digest":"sha256:e25564dccc9110a70a77b9df560cbde11aa392fcb5f08b9abe5c4ebc6d146ea4","pinned_image":"ghcr.io/github/github-mcp-server:v1.5.0@sha256:e25564dccc9110a70a77b9df560cbde11aa392fcb5f08b9abe5c4ebc6d146ea4"},{"image":"mcr.microsoft.com/dotnet-buildtools/prereqs:azurelinux-3.0-binlog-mcp-amd64","digest":"sha256:9f1e2c3e8281186eb1190f39918b23accefefb4dd086d0ac1bd3e4ea7d2ed0e0","pinned_image":"mcr.microsoft.com/dotnet-buildtools/prereqs:azurelinux-3.0-binlog-mcp-amd64@sha256:9f1e2c3e8281186eb1190f39918b23accefefb4dd086d0ac1bd3e4ea7d2ed0e0"}]} # This file was automatically generated by gh-aw (v0.82.8).

From be982a49e4febce4e6c400659d8c2cb192337c99 Mon Sep 17 00:00:00 2001 From: Yuliia Kovalova Date: Thu, 16 Jul 2026 14:48:17 +0200 Subject: [PATCH 07/20] Document why top-level permissions use pull-requests: read gh-aw emits a separate safe_outputs job (granted pull-requests: write + issues: write) for all PR writes; the agent job stays read-only. Add a frontmatter comment explaining this split-permission model so the least-privilege pull-requests: read default isn't repeatedly mistaken for a misconfiguration. No behavior change.

Note: the generated `agentic_commands.yml` command catalog is intentionally left for the repo's normal `gh aw compile` regeneration — the command's `description:` source is updated here, and regenerating that aggregated file locally would also downgrade an unrelated `gh-aw-actions/setup` pin.

If a leg reports **no** errors from `binlog_errors`, that alone does **not** prove it compiled cleanly — a target can fail without emitting an MSBuild error, and non-MSBuild/process failures leave no error records. Before concluding a leg is clean, also check `binlog_overview` and look for failed targets / `OnError` handlers / process-termination clues (see **Defensive Behavior** below). Only when **every** leg shows no errors **and** no failed-target/process evidence should you report that the build compiled cleanly and the failure is elsewhere (most often a test / Helix stage); in that case name the failing stage if you can identify it, link the [Azure DevOps build](${GH_AW_BINLOG_HOST_PATH}), and stop — do **not** invent code fixes.

The agent now calls noop and posts nothing in that case instead of a 'compiled cleanly' summary, so it only comments on genuine build failures.

A ZIP64 size can have ~20 digits, exceeding Bash's signed 64-bit range, where `-gt` errors out and (under `set +e`) an oversized archive could bypass the disk-exhaustion guard. - NU1102/NU1100 guidance: the agent has no network/NuGet tool, so it must base conclusions on binlog feed/version evidence and PR package files and defer upstream-availability checks to a maintainer instead of asserting nuget.org state it cannot verify. - Agent re-reads the PR head via the GitHub API before its first safe-output call and noops if it changed, closing the force-push window that remains after the fetch job's point-in-time revision check.

Concentrate your analysis on the leg(s) that actually report errors (each error has `{ severity, code, message, file, line, column, project }`). 2. For the leg(s) with errors, call `binlog_overview { binlog_file: "" }` for build configuration/context, and `binlog_warnings { binlog_file: "", top: 10 }` when the failure looks like a `WarnAsError` promotion. 3. If a leg reports **no** errors from `binlog_errors`, that alone does **not** prove it compiled cleanly — a target can fail without emitting an MSBuild error, and non-MSBuild/process failures leave no error records. Before concluding a leg is clean, also check `binlog_overview` and look for failed targets / `OnError` handlers / process-termination clues (see **Defensive Behavior** below). Only when **every** leg shows no errors **and** no failed-target/process evidence has the build itself compiled cleanly. This workflow analyses **build** failures only: a clean compile means the pipeline failure is a **non-build** failure (most often a test / Helix / publishing stage), which is out of scope.

Archives with absolute or `..` entry paths are refused up front (defense-in-depth over unzip's own guard); the final destination never uses archive-relative paths.

prefer sourceBranch PR; fix budget accounting MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Guard against stale merges: Azure builds GitHub's refs/pull//merge, so build_json.sourceVersion equals the PR's merge_commit_sha at build time. Compare them in step 4 and again in the pre-activation recheck (and re-read both head and merge in one call), and carry the build merge SHA to the agent (GH_AW_PR_MERGE_SHA) so it re-verifies merge_commit_sha before its first safe output. This catches base-branch advances that leave the PR head unchanged but invalidate the analyzed merge — which the head-only check missed. - On the check_run path, resolve the PR from the build's authoritative sourceBranch (refs/pull//merge) rather than check_run.pull_requests[0], whose order isn't guaranteed and can name a different PR sharing the commit. - Only add an artifact's uncompressed size to the cumulative budget after it actually extracts, so a suspicious-path/extract-failure skip no longer consumes budget and wrongly forces later legs to be dropped as incomplete.

With a shared PR-scoped group + cancel-in-progress, an unrelated check finishing mid-analysis started a no-op run that cancelled the real one. Now only real target-pipeline check_run events (and manual dispatch for a PR) use the PR/head-scoped group; every other event gets a unique per-run group, so unrelated checks can't cancel a running analysis. - Reword the header note: the generated agent job does check out the repository (unconditionally) for agent configuration, using the event's ref and never the PR head — so no PR code is built or executed. ("may run / depending on trigger" was inaccurate.)
