301 the underlying revision storage object | |
302 | |
303 A revlog consists of two parts, an index and the revision data. | |
304 | |
305 The index is a file with a fixed record size containing | |
6912 | 306 information on each revision, including its nodeid (hash), the |
1083 | 307 nodeids of its parents, the position and offset of its data within |
308 the data file, and the revision it's based on. Finally, each entry | |
309 contains a linkrev entry that can serve as a pointer to external | |
310 data. | |
311 | |
312 The revision data itself is a linear collection of data chunks. | |
313 Each chunk represents a revision and is usually represented as a | |
314 delta against the previous chunk. To bound lookup time, runs of | |
315 deltas are limited to about 2 times the length of the original | |
316 version data. This makes retrieval of a version proportional to | |
317 its size, or O(1) relative to the number of revisions. | |
318 | |
319 Both pieces of the revlog are written to in an append-only | |
320 fashion, which means we never need to rewrite a file to insert or | |
321 remove data, and can use some simple techniques to avoid the need | |
322 for locking while reading. | |
