|
Obtaining a revlog revision consists of roughly the following steps:
|
|
|
|
|
|
1. Compute the delta chain
|
|
|
2. Obtain the raw chunks for that delta chain
|
|
|
3. Decompress each raw chunk
|
|
|
4. Apply binary patches to obtain fulltext
|
|
|
5. Verify hash of fulltext
|
|
|
|
|
|
This command measures the time spent in each of these phases.
