397 the underlying revision storage object | |
398 | |
399 A revlog consists of two parts, an index and the revision data. | |
400 | |
401 The index is a file with a fixed record size containing | |
6912 | 402 information on each revision, including its nodeid (hash), the |
1083 | 403 nodeids of its parents, the position and offset of its data within |
404 the data file, and the revision it's based on. Finally, each entry | |
405 contains a linkrev entry that can serve as a pointer to external | |
406 data. | |
407 | |
408 The revision data itself is a linear collection of data chunks. | |
409 Each chunk represents a revision and is usually represented as a | |
410 delta against the previous chunk. To bound lookup time, runs of | |
411 deltas are limited to about 2 times the length of the original | |
412 version data. This makes retrieval of a version proportional to | |
413 its size, or O(1) relative to the number of revisions. | |
414 | |
415 Both pieces of the revlog are written to in an append-only | |
416 fashion, which means we never need to rewrite a file to insert or | |
417 remove data, and can use some simple techniques to avoid the need | |
418 for locking while reading. | |
