20 | Test offset computation to correctly factor in the index entries themselves. | |
|
21 | 21 | Also test that the new data size has the correct size if the transaction is aborted |
|
22 | 22 | after the index has been replaced. |
|
23 | 23 | |
|
24 | Test repo has one small, one moderate and one big change. The clone has | |
|
25 | the small and moderate change and will transition to non-inline storage when | |
|
26 | adding the big change. | |
|
24 | Test repo has commits a, b, c, D, where D is large (grows the revlog enough that it | |
|
25 | transitions to non-inline storage). The clone initially has changes a, b | |
|
26 | and will transition to non-inline storage when adding c, D. | |
|
27 | ||
|
28 | If the transaction adding c, D is rolled back, then we don't undo the revlog split, | |
|
29 | but truncate the index and the data to remove both c and D. | |
