| # This patch series improves Pipenv's reverse dependency handling, JSON output support, and upgrade routines, ensuring more accurate dependency management and better error handling. | ||
|
|
||
| ## Key Changes | ||
|
|
||
| * **Reverse Dependency Graph**: | ||
| * ``graph --reverse`` now supports JSON output, consistent with ``pipdeptree``. | ||
| * Enhanced JSON-tree format for reverse dependencies, improving compatibility with JSON-processing tools. | ||
|
|
||
| * **Improved Upgrade Logic**: | ||
| * Pre-sync step added before conflict analysis to ensure accurate dependency resolution. | ||
| * Early conflict detection prevents incompatible upgrades, improving lock file integrity. | ||
| * Enhanced handling of reverse dependencies to avoid unintended conflicts during updates. | ||
|
|
||
| * **Refactoring & Consistent Output**: | ||
| * Replaced ``click.echo`` calls with ``console`` and ``err`` utilities for consistent output and error handling. | ||
| * Streamlined upgrade logic to reduce installation phases and improve performance. | ||
|
|
||
| ## Bug Fixes | ||
|
|
||
| * Fixed incompatibility when using both ``--json`` and ``--json-tree`` flags simultaneously. | ||
| * Addressed #6281: Resolved transitive dependency conflicts (e.g., ``google-api-core`` vs. ``protobuf``). | ||
| * Updated tests to cover new JSON outputs and compatibility checks. | ||
|
|
||
| ## Impact | ||
|
|
||
| These changes improve accuracy and reliability in complex dependency trees, ensuring robust updates and clearer error reporting. | ||
| Fix dependency resolution edge cases and versioning constraints handling: | ||
| * Allow JSON format options for ``--reverse`` dependency graph output matching pipdeptree | ||
| * Improve installation and upgrade routines to better handle dependencies | ||
| * Add ability to specify json output as pipdeptree does | ||
| * Add more consistent handling of VCS dependencies and references | ||
| * Fix synchronization of development and default dependencies during updates | ||
| * Ensure proper propagation of version constraints during updates | ||
| * Fix handling of ``~=`` and other version specifiers during updates | ||
|
|
||
| Key Changes: | ||
| * Improved reverse dependency analysis to catch conflicts earlier in resolution | ||
| * Better handling of VCS package lock data, preserving refs and subdirectories | ||
| * Fixed issue where VCS references could be lost in lock file when installed via commit hash | ||
| * Better handling of pipfile categories during installation and updates | ||
| * Corrected logic for development dependency resolution and constraint propagation | ||
| * Improved validation and preservation of version specifiers during updates | ||
|
|
||
| This improves stability when working with complex dependency trees and version constraints. |
