| Use streams instead of APR files to read patch files. |
| ===================================================== |
| |
| 2025-05-16: The patch parser currently uses APR files to read |
| and parse patch files. Convert it to use SVN streams instead, |
| as it's more flexible and doesn't strictly rely on on-disk files. |
| |
| |
| ISSUES: |
| - Reading patches currently relies heavily on seeking in the file. |
| This is really supported only in file-based and string-based streams, |
| and not even all of those (e.g., (de)compressed and tee'd streams |
| don't support seek even if there's an underlying file). That makes |
| reading patches from streams less flexible than it could be. |
| |
| Still, by converting to reading from streams, we're not reducing |
| existing features; all current use cases for reading patches remain |
| supported, because file-based streams always support mark and seek. |
| |
| And now, they also support span, i.e., finding the distance between |
| two stream marks, just like for two file positions. |
