| 3 # revlog.parseindex must be able to parse the index file even if | |
| 4 # an index entry is split between two 64k blocks. The ideal test | |
| 5 # would be to create an index file with inline data where | |
| 6 # 64k < size < 64k + 64 (64k is the size of the read buffer, 64 is | |
| 7 # the size of an index entry) and with an index entry starting right | |
| 8 # before the 64k block boundary, and try to read it. | |
| 9 # | |
| 10 # We approximate that by reducing the read buffer to 1 byte. | |
