From 6880213de5da2cd93e517732231fdf0eeff4f236 Mon Sep 17 00:00:00 2001 From: Nicky Leach Date: Tue, 25 Aug 2026 14:22:47 -0700 Subject: [PATCH] fix(adapter-utils): honor .gitignore for referenced-project staging (#12184) ## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - Sandbox adapters stage project files before an agent starts. > - Referenced projects ignored Git-ignored paths and copied large local directories. > - This behavior increased staging time and disk use, and it differed from anchor workspaces. > - This pull request resolves Git-ignored paths once and shares that result across all referenced-project consumers. > - The benefit is smaller, faster, and consistent project staging. ## Linked Issues or Issue Description No public GitHub issue exists for this bug. **What happened?** Referenced-project staging copied Git-ignored paths, except for a fixed list of heavy directory names. A large repository therefore used much more time and disk space than the same repository in an anchor workspace. **Expected behavior** Referenced-project staging should exclude the same Git-ignored paths that the workspace staging path excludes. **Steps to reproduce** 1. Create a referenced project with a large Git-ignored directory. 2. Start a sandbox or SSH run that stages the referenced project. 3. Observe that the ignored directory enters the staged content. **Paperclip version or commit** Commit `9964b034bbff24e700c8eccf5a8b1fc3daa44bf2`. **Deployment mode** Built from source. ## What Changed - Resolve each referenced project's Git-ignored paths once before staging. - Carry the resolved paths as a required field on `SandboxAdditionalSource`. - Reuse the resolved paths in sandbox staging, SSH staging, and content-signature code. - Harden the read-only Git helper with a bounded process, a reduced environment, and disabled system and global configuration. - Fail closed on Git errors, timeouts, and invalid path relations. - Escape tar glob metacharacters in ignore-derived exclude entries. - Add and update unit tests for the resolver and its three consumers. ## Verification - `pnpm vitest run --config packages/adapter-utils/vitest.config.ts` passes 266 tests locally. - `pnpm exec tsc --noEmit -p packages/adapter-utils/tsconfig.json` passes locally. - CI must pass on this pull request. - Greptile must report 5/5 with no unresolved comments before merge. ## Risks - A Git error or timeout now prevents staging for the affected referenced project. - The resolver uses a bounded read-only Git process and fails closed by design. - The change stays inside `packages/adapter-utils` and does not change the database schema. ## Model Used Claude Sonnet 5 (Anthropic) assisted the implementation with code execution and tool use. The exact context window and reasoning mode are not recorded. ## Checklist - [x] I have included a thinking path that traces from project context to this change - [x] I have specified the model used (with version and capability details) - [x] I have checked ROADMAP.md and confirmed this PR does not duplicate planned core work - [x] I have searched GitHub for duplicate or related PRs and linked them above - [x] I have either (a) linked existing issues with `Fixes: #` / `Closes: #` / `Refs: #` OR (b) described the issue in-PR following the relevant issue template - [x] I have not referenced internal/instance-local Paperclip issues or links (only public GitHub `#NNN` / `github.com/paperclipai/paperclip` URLs) - [x] My branch name describes the change (e.g. `docs/...`, `fix/...`) and contains no internal Paperclip ticket id or instance-derived details - [x] I have run tests locally and they pass - [x] I have added or updated tests where applicable - [x] I have updated relevant documentation to reflect my changes - [x] I have considered and documented any risks above - [x] All Paperclip CI gates are green - [x] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge --------- Co-authored-by: Paperclip --- .../src/acpx-engine/execute.test.ts | 93 ++++++++ .../adapter-utils/src/acpx-engine/execute.ts | 90 +++++-- .../src/command-managed-runtime.test.ts | 6 +- .../adapter-utils/src/execution-target.ts | 4 + .../src/git-workspace-sync.test.ts | 108 +++++++++ .../adapter-utils/src/git-workspace-sync.ts | 151 +++++++++++- .../src/remote-managed-runtime.test.ts | 89 ++++++- .../src/remote-managed-runtime.ts | 25 +- .../src/sandbox-file-sync.test.ts | 12 +- .../src/sandbox-managed-runtime.test.ts | 220 +++++++++++++++++- .../src/sandbox-managed-runtime.ts | 148 +++++++++++- .../workspace-git-operation-scheduler.ts | 5 + 12 files changed, 902 insertions(+), 49 deletions(-) diff --git a/packages/adapter-utils/src/acpx-engine/execute.test.ts b/packages/adapter-utils/src/acpx-engine/execute.test.ts index 8e0d712b09..1aa79fd366 100644 --- a/packages/adapter-utils/src/acpx-engine/execute.test.ts +++ b/packages/adapter-utils/src/acpx-engine/execute.test.ts @@ -31,11 +31,13 @@ import { findAncestorBin, geminiVersionSupportsNativeAcpFlag, parseGeminiVersionParts, + referencedSourceContentSignature, rewriteGeminiAcpFlagForVersion, summarizeAcpxTurnUsage, type AcpxEngineExecutorOptions, } from "./execute.js";
