419 the underlying revision storage object | |
420 | |
421 A revlog consists of two parts, an index and the revision data. | |
422 | |
423 The index is a file with a fixed record size containing | |
424 information on each revision, includings its nodeid (hash), the | |
425 nodeids of its parents, the position and offset of its data within | |
426 the data file, and the revision it's based on. Finally, each entry | |
427 contains a linkrev entry that can serve as a pointer to external | |
428 data. | |
429 | |
430 The revision data itself is a linear collection of data chunks. | |
431 Each chunk represents a revision and is usually represented as a | |
432 delta against the previous chunk. To bound lookup time, runs of | |
433 deltas are limited to about 2 times the length of the original | |
434 version data. This makes retrieval of a version proportional to | |
435 its size, or O(1) relative to the number of revisions. | |
436 | |
437 Both pieces of the revlog are written to in an append-only | |
438 fashion, which means we never need to rewrite a file to insert or | |
439 remove data, and can use some simple techniques to avoid the need | |
440 for locking while reading. | |
