Problem

With Follow change request templates enabled, Azure DevOps repositories never supplied a template to the description generator because their source-control provider had no template reader. Addresses #22871.

Change

Add a local Git reader following the GitLab implementation: inspect committed regular blobs in .azuredevops, .vsts, docs, then the repository root, accepting case-insensitive pull_request_template.md and .txt names. Read from the primary remote's locally recorded default branch even when the PR targets a release branch. Keep the same absent, blank, bounded-output and truncation behavior as GitLab. No Azure API calls or credentials are needed for template discovery.

Scope and approval

Fixes #22871

Triaged bug via the automated issue flow.

Limits: local remote HEAD metadata must be available and current; otherwise discovery returns no template. Branch-specific templates are outside this fix, matching the default-template scope of the GitLab reader. Tree listings and template content remain bounded. cannot-verify azure live; evidence uses temporary local Git repositories, with external Azure operations mocked. No UI behavior changed, so screenshots are not applicable.

Verification

Validation:

Before: both fixture test files failed, 10/10 tests, because the Azure reader was absent and GitManager passed no template.
After: vp test run apps/server/src/sourceControl/azureDevOpsChangeRequestTemplate.test.ts apps/server/src/git/GitManager.azureDevOpsTemplate.test.ts — 2 files passed, 16 tests passed.
The GitManager fixture runs the real create_pr path with the setting enabled and checks the template passed to the description generator, including release targets with different or missing templates.
Targeted lint and Azure DevOps/server package typechecks passed.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — Azure DevOps PR generation will now follow repository templates with bounded, read-only Git access. Because template following is enabled by default, this changes default generated descriptions and requires human confirmation.

Walkthrough

The Azure DevOps source-control provider now reads pull-request templates from the repository’s remote default branch. Template detection searches supported locations, filters file types, limits content size, and returns no template when detection fails.

Changes: Azure DevOps template discovery

Layer / File(s)	Summary
Detect and expose templates `packages/source-control-azure-devops/src/server/azureDevOpsChangeRequestTemplate.ts`, `packages/source-control-azure-devops/src/server/AzureDevOpsSourceControlProvider.ts`, `packages/source-control-azure-devops/src/server/AzureDevOpsSourceControlProvider.test.ts`	The provider resolves the primary remote’s symbolic `HEAD` and passes the default branch to the detector. The detector searches supported locations, selects regular `.md` or `.txt` files, limits reads to 8,000 bytes, and returns no template for blank content or failures.
Verify template selection and filtering `packages/source-control-azure-devops/src/server/AzureDevOpsSourceControlProvider.git.test.ts`	Tests cover default-branch selection, location precedence, case-insensitive names, missing or invalid templates, truncation, and an unknown remote default branch.

No actionable merge-blocking risk remains. The template reader retains the intended fallback, and the test no longer requires filesystem symlink privileges.

Explanation

Issue #22871 requires Azure DevOps template discovery when the setting is enabled. AzureDevOpsSourceControlProvider.readChangeRequestTemplate now resolves the primary remote's local default-branch ref and invokes the detector. The detector searches the required locations, accepts case-insensitive .md and .txt names, reads regular committed blobs, preserves bounded and truncation behavior, and returns no template for missing or invalid metadata. Tests cover default-branch reads for release targets, precedence, case handling, invalid entries, truncation, and unknown remote HEAD metadata.

Full details: Out of Scope Changes check

Explanation

The provider and detector implement issue #22871. The temporary-repository tests verify the required discovery behavior and the create_pr integration boundary. The reviewed change summary shows no unrelated product behavior or UI changes.

Create the symlink in the Git index instead.

If a Windows developer lacks symlink privileges and Developer Mode, NodeFS.symlinkSync can fail before this test checks the provider. Create a mode 120000 entry in the Git index to test the committed symlink without requiring an operating-system symlink. (learn.microsoft.com)

104-122: External image Trivial · Maintainability & Code Quality
External image Unverified finding Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Risk: refs/remotes/<remote>/HEAD may be stale or missing.
The reader runs git symbolic-ref refs/remotes/<remote>/HEAD. Git does not update this ref on git fetch. If the remote's default branch is renamed, the reader keeps using the old branch. The PR objectives accept this as a documented limit, so this is not a defect. The code does swallow every failure, including a missing ref, into Option.none(). Users get no signal about why a template was not found. A debug-level log at the orElseSucceed site would help diagnosis.
Optional: log the failure before it is mapped to Option.none().

The automated pipeline stopped on this pull request and will not merge it:

these checks fail on 5fff2877e7, also when run again: Check, Test Web, and the rework changed nothing:

No code change: the failing checks are not caused by this PR. Test Web failed on one test, apps/web/src/components/RightPanelTabs.browser.test.tsx ('a flick that scrolls the tab strip to its left edge keeps the thread, a swipe from the edge goes back'), and Check fails only because it requires every job to pass. Reproduced locally with vp test run on the branch head: it failed 3 of 3 runs. Ran the same command on current origin/main (c82e1ba515), where RightPanelTabs.tsx and its test are identical to the branch's copies, and it fails there too. This PR changes only four files in packages/source-control-azure-devops and nothing in apps/web. The failure belongs to main (the test or its component was last changed there by #33396), so the branch head is unchanged. The Azure DevOps template reader, its tests and the Windows-safe symlink fixture from the previous round stand as pushed.

It stays open for a person to finish or close.

JJulius Marminge10h ago

The automated pipeline stopped on this pull request and will not merge it:

the capture step could not show the problem on the base commit, so there is nothing to prove fixed.

On each commit, created a synthetic repository with a committed .azuredevops/pull_request_template.md containing Context and Verification headings; configured an Azure DevOps origin, origin/main, and remote HEAD; committed a feature-branch change and configured its upstream; opened the real app and clicked Create PR. Follow change request templates retained its enabled default. Both runs stopped at the missing Azure CLI error before description generation.

It stays open for a person to finish or close.
