From 412dbc29f8841d13b4fe4b4b88500acaaa5b7cdb Mon Sep 17 00:00:00 2001 From: Sridhar Ratnakumar Date: Fri, 24 Apr 2026 21:06:04 -0400 Subject: [PATCH 1/5] feat(install): add --root flag to redirect deploy paths `apm install --root ` writes apm_modules/, apm.lock.yaml, and runtime deployment dirs (.claude/, .codex/, .agents/, .opencode/) under while sources (apm.yml, .apm/, local-path packages) continue resolving from $PWD. Mirrors `pip install --target` and `npm install --prefix`. Useful for scratch-dir verification (microsoft/apm#684), bootstrap scripts, and fixture generation -- closes microsoft/apm#888. Implementation - core/scope.py: process-global deploy-root override (set_deploy_root_override) plus a separate get_source_root() that always resolves to $PWD. get_manifest_path is decoupled from get_apm_dir so the manifest stays in $PWD even when writes redirect. - install/context.py: InstallContext gains source_root, defaulting to project_root for back-compat. - install/pipeline.py: passes source_root into the context. _project_has_root_primitives runs against source_root. - install/services.py: integrate_local_content takes an optional source_root for the synthetic _local package's install_path. - install/phases/{resolve,integrate}.py: thread source_root through to local-package resolution and local-content integration. - commands/install.py: --root option, mutually exclusive with --global; sets the override at entry, clears it in finally so no global state leaks across invocations. --- src/apm_cli/commands/install.py | 42 ++++++++++-- src/apm_cli/core/scope.py | 86 ++++++++++++++++++++++--- src/apm_cli/install/context.py | 12 ++++ src/apm_cli/install/phases/integrate.py | 1 + src/apm_cli/install/phases/resolve.py | 6 +- src/apm_cli/install/pipeline.py | 14 ++-- src/apm_cli/install/services.py | 18 +++++- src/apm_cli/install/sources.py | 3 +- 8 files changed, 162 insertions(+), 20 deletions(-) diff --git a/src/apm_cli/commands/install.py b/src/apm_cli/commands/install.py index c56aa454c..4ae4edb7e 100644 --- a/src/apm_cli/commands/install.py +++ b/src/apm_cli/commands/install.py @@ -1057,8 +1057,23 @@ def _run_mcp_install( default=False, help="Skip org policy enforcement for this invocation.

Sources keep reading from the original $PWD via set_source_root_override. Why chdir - The previous override only covered scope helpers (get_deploy_root/get_apm_dir). MCP adapters bypass those helpers and write directly to Path.cwd() / opencode.json, .vscode/mcp.json, .cursor/mcp.json, etc. Refactoring the long tail of cwd/getcwd call-sites is more invasive than the chdir trick and would block this feature on a wider cleanup. Implementation - new module: apm_cli.install.root_redirect.install_root_redirect context manager (chdir + source-root pin, restored on exit). - core/scope.py: replace deploy override with source-root override; get_manifest_path now derives from get_source_root. - commands/install.py: bracket the handler body with the context manager (enter at top, __exit__ in finally).

DistributedAgentsCompiler already does this right at distributed_compiler.py:594; this closes the asymmetry. Also documents the source-vs-deploy routing convention on `get_lockfile_dir` so a future maintainer adding a new metadata helper picks the right root without tracing callers.
