| <div class="sectionbody"> | |
| <div class="paragraph"><p>When <code>receive-pack</code> takes in objects, they are placed into a temporary | |
| "quarantine" directory within the <code>$GIT_DIR/objects</code> directory and | |
| migrated into the main object store only after the <code>pre-receive</code> hook | |
| has completed. If the push fails before then, the temporary directory is | |

| <div class="paragraph"><p>This has a few user-visible effects and caveats:</p></div> | |
| <div class="olist arabic"><ol class="arabic"> | |
| <li> | |
| <p> | |
| Pushes which fail due to problems with the incoming pack, missing | |
| objects, or due to the <code>pre-receive</code> hook will not leave any | |
| on-disk data. This is usually helpful to prevent repeated failed | |
| pushes from filling up your disk, but can make debugging more | |
| challenging. | |
| </p> | |
| </li> | |
| <li> | |
| <p> | |
| Any objects created by the <code>pre-receive</code> hook will be created in | |
| the quarantine directory (and migrated only if it succeeds). | |
| </p> | |
| </li> | |
| <li> | |
| <p> | |
| The <code>pre-receive</code> hook MUST NOT update any refs to point to | |
| quarantined objects. Other programs accessing the repository will | |
| not be able to see the objects (and if the pre-receive hook fails, | |
| those refs would become corrupted). For safety, any ref updates | |
| from within <code>pre-receive</code> are automatically rejected. | |
