From fa6d594b7af47da62565a1a23d5cdd4eae7dd5d5 Mon Sep 17 00:00:00 2001 From: MK Date: Thu, 9 Oct 2025 11:14:37 +0800 Subject: [PATCH 1/4] feat(task): add cache fingerprint ignore patterns MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Allow tasks to exclude specific files/directories from cache fingerprint calculation using glob patterns with gitignore-style negation support. This enables selective caching for tasks like package installation where only dependency manifests (package.json) matter for cache validation, not implementation files. Cache hits occur when ignored files change. Key features: - Optional fingerprintIgnores field accepts glob patterns - Negation patterns (!) to include files within ignored directories - Leverages existing vite_glob crate for pattern matching - Fully backward compatible (defaults to None) Example: { "fingerprintIgnores": [ "node_modules/**/*", "!node_modules/**/package.json" ] } 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .../rfc-cache-fingerprint-ignore-patterns.md | 348 ++++++++++++++++++ .../fingerprint-ignore-test/README.md | 55 +++ .../fingerprint-ignore-test/package.json | 4 + .../fingerprint-ignore-test/vite-task.json | 13 + crates/vite_task/src/cache.rs | 4 +- crates/vite_task/src/config/mod.rs | 3 + crates/vite_task/src/config/task_command.rs | 1 + crates/vite_task/src/execute.rs | 3 + crates/vite_task/src/fingerprint.rs | 17 + crates/vite_task/src/schedule.rs | 7 +- 10 files changed, 453 insertions(+), 2 deletions(-) create mode 100644 crates/vite_task/docs/rfc-cache-fingerprint-ignore-patterns.md create mode 100644 crates/vite_task/fixtures/fingerprint-ignore-test/README.md create mode 100644 crates/vite_task/fixtures/fingerprint-ignore-test/package.json create mode 100644 crates/vite_task/fixtures/fingerprint-ignore-test/vite-task.json diff --git a/crates/vite_task/docs/rfc-cache-fingerprint-ignore-patterns.md b/crates/vite_task/docs/rfc-cache-fingerprint-ignore-patterns.md new file mode 100644 index 0000000000..47b325aa1e --- /dev/null +++ b/crates/vite_task/docs/rfc-cache-fingerprint-ignore-patterns.md @@ -0,0 +1,348 @@ +# RFC: Vite+ Cache Fingerprint Ignore Patterns + +## Summary + +Add support for glob-based ignore patterns to the cache fingerprint calculation, allowing tasks to exclude specific files/directories from triggering cache invalidation while still including important files within ignored directories. + +## Motivation + +Current cache fingerprint behavior tracks all files accessed during task execution.

charset=UTF-8 Content-Transfer-Encoding: 8bit Add comprehensive snap-test demonstrating cache fingerprint ignore patterns. The test verifies: - Cache hit when ignored files change (node_modules/*/index.js, dist/*) - Cache miss when non-ignored files change (package.json via negation) - Negation patterns work correctly (!node_modules/**/package.json) Test scenario: 1. First run - cache miss (initial execution) 2. Second run - cache hit (no changes) 3. Modify index.js - cache hit (ignored by node_modules/**/* pattern) 4. Modify dist/bundle.js - cache hit (ignored by dist/**/* pattern) 5. Modify package.json - cache miss (NOT ignored due to negation pattern) This validates the selective caching feature for package installation tasks where only dependency manifests matter for cache validation. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .../rfc-cache-fingerprint-ignore-patterns.md | 219 ++++++-- crates/vite_task/src/cache.rs | 8 +- crates/vite_task/src/config/mod.rs | 23 +- crates/vite_task/src/config/task_command.rs | 3 +- crates/vite_task/src/execute.rs | 1 + crates/vite_task/src/fingerprint.rs | 471 +++++++++++++++++- crates/vite_task/src/install.rs | 1 + .../fingerprint-ignore-test/package.json | 4 + .../fingerprint-ignore-test/snap.txt | 87 ++++ .../fingerprint-ignore-test/steps.json | 18 + .../fingerprint-ignore-test/vite-task.json | 13 + 11 files changed, 799 insertions(+), 49 deletions(-) create mode 100644 packages/cli/snap-tests/fingerprint-ignore-test/package.json create mode 100644 packages/cli/snap-tests/fingerprint-ignore-test/snap.txt create mode 100644 packages/cli/snap-tests/fingerprint-ignore-test/steps.json create mode 100644 packages/cli/snap-tests/fingerprint-ignore-test/vite-task.json diff --git a/crates/vite_task/docs/rfc-cache-fingerprint-ignore-patterns.md b/crates/vite_task/docs/rfc-cache-fingerprint-ignore-patterns.md index 47b325aa1e..dc7b54342b 100644 --- a/crates/vite_task/docs/rfc-cache-fingerprint-ignore-patterns.md +++ b/crates/vite_task/docs/rfc-cache-fingerprint-ignore-patterns.md @@ -76,7 +76,34 @@ pub struct TaskConfig { } ``` -#### 2.
