7 | 7 | # The Goal is to produce two repositories with some common part and some |
|
8 | 8 | # exclusive part on each side. Provide a source repository REPO, it will |
|
9 | 9 | # produce two repositories REPO-left and REPO-right. |
|
10 | 10 | # |
|
11 | 11 | # Each repository will be missing some revisions exclusive to NBHEADS of the |
|
12 | 12 | # repo topological heads. These heads and revisions exclusive to them (up to |
|
13 | 13 | # DEPTH depth) are stripped. |
|
14 | 14 | # |
|
15 | 15 | # The "left" repository will use the NBHEADS first heads (sorted by |
|
16 | 16 | # description). The "right" use the last NBHEADS one. |
|
17 | 17 | # |
|
18 | 18 | # To find out how many topological heads a repo has, use: |
|
19 | 19 | # |
|
20 | 20 | # $ hg heads -t -T '{rev}\n' | wc -l |
|
21 | 21 | # |
|
22 | 22 | # Example: |
|
23 | 23 | # |
|
24 | 24 | # The `pypy-2018-09-01` repository has 192 heads. To produce two repositories |
|
25 | 25 | # with 92 common heads and ~50 exclusive heads on each side. |
|
