Subject: [PATCH 1/6] Fix issue #65: Check source directories exist before
 writing to requirements

When using mxdev -n (no-fetch) or in offline mode, source directories may
not exist yet. Previously, mxdev would write references like '-e ./sources/package'
to requirements-mxdev.txt regardless, causing pip install to fail later.

This fix checks if source directories exist before writing them:
- If directory exists: Write normally (existing behavior)
- If directory doesn't exist: Write as comment with contextual warning

The warning message adapts based on context:
- In offline mode: Mentions offline mode and suggests removing -n and --offline flags
- Normal mode: Suggests removing -n flag to fetch sources

This fixes the mxmake two-stage installation workflow where mxdev -n runs
before sources are checked out.

Changes:
- Update write_dev_sources() to accept State parameter and check path existence
- Add contextual warning messages for missing directories
- Add tests for missing directories and offline mode warnings
- Update existing tests to pass State parameter

Fixes #65

 - Feature: #54: Add `fixed` install mode for non-editable installations to support production and Docker deployments. The new `editable` mode replaces `direct` as the default (same behavior, clearer naming). The `direct` mode is now deprecated but still works with a warning. Install modes: `editable` (with `-e`, for development), `fixed` (without `-e`, for production/Docker), `skip` (clone only).
   [jensens]
+- Fix #65: When generating requirements-mxdev.txt, check if source directories actually exist before writing package references. If a source directory doesn't exist (e.g., when using `mxdev -n` without prior fetch, or in offline mode), write it as a comment with a contextual warning instead of causing pip install to fail later. This fixes the mxmake two-stage installation workflow where `mxdev -n` runs before sources are checked out. Warning messages include context about offline mode when applicable.

 - Fix #35: Add `smart-threading` configuration option to prevent overlapping credential prompts when using HTTPS URLs. When enabled (default), HTTPS packages are processed serially first to ensure clean credential prompts, then other packages are processed in parallel for speed. Can be disabled with `smart-threading = false` if you have credential helpers configured.
   [jensens]
 - Fix #34: The `offline` configuration setting and `--offline` CLI flag are now properly respected to prevent VCS fetch/update operations. Previously, setting `offline = true` in mx.ini or using the `--offline` CLI flag was ignored, and VCS operations still occurred.

Subject: [PATCH 2/6] Fix #65: Make missing sources fatal error in non-offline
 mode

In offline mode:
- Missing sources log WARNING (expected)
- Packages written as comments
- mxdev continues

In non-offline mode:
- Missing sources log ERROR (fatal)
- Packages written as comments
- mxdev raises RuntimeError and exits

This prevents silent failures when sources fail to checkout
and makes mxmake two-stage installation more robust.

Tests:
- Updated test_write_dev_sources_missing_directories to use offline mode
- Added test_write_dev_sources_missing_directories_raises_error
- All 7 write_dev_sources tests pass

 - Feature: #54: Add `fixed` install mode for non-editable installations to support production and Docker deployments. The new `editable` mode replaces `direct` as the default (same behavior, clearer naming). The `direct` mode is now deprecated but still works with a warning. Install modes: `editable` (with `-e`, for development), `fixed` (without `-e`, for production/Docker), `skip` (clone only).
   [jensens]
-- Fix #65: When generating requirements-mxdev.txt, check if source directories actually exist before writing package references. If a source directory doesn't exist (e.g., when using `mxdev -n` without prior fetch, or in offline mode), write it as a comment with a contextual warning instead of causing pip install to fail later. This fixes the mxmake two-stage installation workflow where `mxdev -n` runs before sources are checked out. Warning messages include context about offline mode when applicable.
+- Fix #65: Check source directories exist before writing to requirements-mxdev.txt. In **offline mode**: missing sources log WARNING and are written as comments (expected behavior). In **non-offline mode**: missing sources log ERROR and mxdev exits with RuntimeError (fatal error indicating checkout failure). This fixes mxmake two-stage installation workflow and prevents silent failures when sources fail to check out.
   [jensens]
 - Fix #35: Add `smart-threading` configuration option to prevent overlapping credential prompts when using HTTPS URLs. When enabled (default), HTTPS packages are processed serially first to ensure clean credential prompts, then other packages are processed in parallel for speed. Can be disabled with `smart-threading = false` if you have credential helpers configured.

 ## 5.0.1 (unreleased)
 
+- Fix #65: Check source directories exist before writing to requirements-mxdev.txt. In **offline mode**: missing sources log WARNING and are written as comments (expected behavior). In **non-offline mode**: missing sources log ERROR and mxdev exits with RuntimeError (fatal error indicating checkout failure). This fixes mxmake two-stage installation workflow and prevents silent failures when sources fail to check out.
+  [jensens]
 - Fix: Add 'synchronize' event to pull_request workflow triggers. This ensures CI runs when PRs are updated with new commits (e.g., after rebasing or pushing new changes), not just when opened or reopened.
   [jensens]
 - Chore: Optimize GitHub Actions to prevent duplicate workflow runs on pull requests. Restrict `push` trigger to only run on `main` branch, so PRs only trigger via `pull_request` event. This reduces CI resource usage by 50% for PR workflows.

   [jensens]
 - Feature: #54: Add `fixed` install mode for non-editable installations to support production and Docker deployments. The new `editable` mode replaces `direct` as the default (same behavior, clearer naming). The `direct` mode is now deprecated but still works with a warning. Install modes: `editable` (with `-e`, for development), `fixed` (without `-e`, for production/Docker), `skip` (clone only).

-- Fix #65: Check source directories exist before writing to requirements-mxdev.txt. In **offline mode**: missing sources log WARNING and are written as comments (expected behavior). In **non-offline mode**: missing sources log ERROR and mxdev exits with RuntimeError (fatal error indicating checkout failure). This fixes mxmake two-stage installation workflow and prevents silent failures when sources fail to check out.
-  [jensens]
 - Fix #35: Add `smart-threading` configuration option to prevent overlapping credential prompts when using HTTPS URLs. When enabled (default), HTTPS packages are processed serially first to ensure clean credential prompts, then other packages are processed in parallel for speed. Can be disabled with `smart-threading = false` if you have credential helpers configured.
   [jensens]
 - Fix #34: The `offline` configuration setting and `--offline` CLI flag are now properly respected to prevent VCS fetch/update operations. Previously, setting `offline = true` in mx.ini or using the `--offline` CLI flag was ignored, and VCS operations still occurred.

Subject: [PATCH 5/6] Fix: Remove duplicate test functions after rebase
 conflict

During rebase conflict resolution, test_process_line_package_in_override_keys
and test_process_line_package_in_ignore_keys were accidentally duplicated.

Removed duplicates, keeping only one copy of each test.
