Windows Server 2025 (windows-latest) has path length issues causing
"Could not find a part of the path D:\a" errors during job setup.
Windows Server 2022 is more stable.
- CI now runs both Linux and Windows by default (matrix)
- Updated install.sh to detect Windows venv path (Scripts/ vs bin/)
- Added Windows installation instructions to getting-started.md
- Updated troubleshooting guide with Git Bash guidance
- Windows uses Git Bash for cross-platform bash script compatibility
Subprocess pipes on Windows use cp1252 by default which fails
when reading UTF-8 output. PYTHONUTF8=1 forces Python to use
UTF-8 for all I/O operations.
Windows uses cp1252 encoding by default which doesn't support
emoji characters. Setting PYTHONIOENCODING=utf-8 fixes the
UnicodeEncodeError when Rich prints the banner with emojis.
- Add 'os' input parameter (linux/windows/all)
- Default to Linux for all automatic triggers
- Manual dispatch can select Windows for experimental testing
- Stages 1-5 now support OS matrix
- Stages 6-7 remain Linux-only (release/fresh-install)
This enables progressive Windows testing to identify compatibility
issues before committing to full Windows support.
Fork PRs have branches that don't exist in harvard-edge/cs249r_book,
so the install script URL is invalid. Skip Fresh Install for fork PRs
and run it only for:
- Direct pushes to dev/main
- PRs from branches within the same repo
The dev deploy workflow was accidentally lost when it was "combined"
into tinytorch-ci.yml, but the deploy step was never actually added.
Restores the exact original workflow to deploy TinyTorch site to dev
preview on push to dev branch.
Previously stages ran sequentially (1->2->3->4->5), meaning if
integration tests failed, CLI tests would be skipped even though
they dont actually depend on each other.
New structure:
- Stage 1 (Inline Build): Foundation
- Stages 2, 3, 4 (Unit, Integration, CLI): Run in PARALLEL after Stage 1
- Stage 5 (E2E): Runs only if ALL of stages 2-4 pass
Benefits:
- Faster CI (parallel execution)
- See all test results even if one category fails
- E2E still gates on everything passing
- Add TINYTORCH_NON_INTERACTIVE env var to install.sh for CI/scripted usage
- Skip interactive prompts when no TTY available or non-interactive mode set
- Add Stage 7 (Fresh Install) to tinytorch-ci.yml
- Remove separate tinytorch-install-test.yml workflow
- Fresh install now gates PRs/merges like other tests
- Change Python version from 3.13 to 3.11 for consistency with other workflows
- Install project dependencies before running pre-commit hooks
- Add verbose output to help debug pre-commit failures
- Show Python version in logs for debugging
- Remove Stage 6 (milestone tests) from CI workflow since test files were
removed as redundant with integration tests
- Renumber Stage 7 (release) to Stage 6
- Update summary job to remove milestone references
- Fix _trigger_submission() to skip interactive prompts in CI mode
by checking CI, GITHUB_ACTIONS env vars and stdin.isatty()
The milestone demo scripts remain available for student use via
'tito milestone run', but are no longer run as automated tests.
Instead of using brittle regex patterns to extract username and then
passing just the description to the LLM, now the LLM parses the entire
trigger line and extracts:
- GitHub username (handles @user, hyphenated names, various formats)
- Contribution type(s)
- Target project (if mentioned)
This handles natural language like:
- '@all-contributors please add @didier-durand to doc in book'
- '@all-contributors @jane-doe fixed typos'
- '@all-contributors @user123 helped verify the fix worked'
Includes fallback regex extraction if LLM fails to find username.
Fixes issue from PR #1133 where 'please add' syntax wasn't recognized.
- Update all-contributors-add.yml to use Ollama (llama3.1:8b) for parsing
natural language descriptions instead of requiring exact syntax
- Trim contribution types to 8 actually used: bug, code, doc, design,
ideas, review, test, tool
- Update generate_main_readme.py and generate_readme_tables.py to match
- Remove unused tito module export subcommand (fixes#1134)
Students should use tito module complete instead
Now you can write naturally:
@all-contributors @user helped verify the fix worked
@all-contributors @user found a bug in the dataloader

- Remove '@all-contributors please add' instruction from contributors section
- Replace 'Built with dedication' with 'Made with ❤️ for AI learners worldwide'
- Update generate_main_readme.py to not regenerate the removed instruction
- Changed from 7 columns to 9 columns per row
- Reduced avatar size from 80px to 50px
- Makes the contributor section more scannable and takes less vertical space
E2E test fixes:
- Add TITO_ALLOW_SYSTEM=1 env var to run_tito() for tests outside venv
- Fix CLI command naming: 'milestones' → 'milestone' (singular)
- Fix modules directory path: 'modules/' → 'src/'
CI improvements:
- Remove continue-on-error from E2E and CLI test steps
- Add test summary table to job output showing pass/fail for each suite
- Add JUnit XML output for test results

E2E tests have CLI command naming issues (e.g., 'milestones' vs 'milestone').
These need separate attention to fix. Making them non-blocking until fixed.

Coverage check was failing because the coverage config in pyproject.toml
doesn't apply correctly to the integration/e2e/cli/regression test directories.
These tests don't need coverage tracking.

Push to dev now:
1. Runs all tests (student journey, integration, E2E, CLI, regression)
2. Only if tests pass, deploys to dev preview site
Removed separate tinytorch-publish-dev.yml - all in tinytorch-ci.yml now.

Run all tests on dev pushes:
1. Student journey (20 modules + milestones)
2. Integration tests
3. E2E tests
4. CLI tests
5. Regression tests

Simple CI: push to dev runs full test suite via tito dev validate.
Tests all 20 modules and all milestones.

- Create draft GitHub Release after tag is created
- Auto-generate changelog from commits since last tag
- Release is created as draft for review before publishing
- Updated job name to 'Create Tag & Release'

- Remove __init__.py version update step (now reads from pyproject.toml dynamically)
- Update comments to reflect 5 files instead of 6
- pyproject.toml is now the single source of truth for TinyTorch version
