|---|
| 7 | # post-commit-background REPOS REV |
|---|
| 8 | # |
|---|
| 9 | # DESCRIPTION |
|---|
| 10 | # This script performs the Subversion post-commit tasks in the background. The |
|---|
| 11 | # first argument must be the path to the current Subversion repository, and |
|---|
| 12 | # the second argument must be the revision of the current commit. Errors in |
|---|
| 13 | # the script are automatically e-mailed to the FCM user account. |
|---|
| 14 | # |
|---|
| 15 | # The script does the following: |
|---|
| 16 | # 1. updates the "latest" file in the log directory with the latest revision |
|---|
| 17 | # number of the repository. |
|---|
| 18 | # 2. creates an incremental revision dump of the current revision. |
|---|
| 19 | # 3. runs "background_updates.pl" if it exists in the hook script directory. |
