| 288 the underlying revision storage object | |
| 289 | |
| 290 A revlog consists of two parts, an index and the revision data. | |
| 291 | |
| 292 The index is a file with a fixed record size containing | |
| 293 information on each revision, includings its nodeid (hash), the | |
| 294 nodeids of its parents, the position and offset of its data within | |
| 295 the data file, and the revision it's based on. Finally, each entry | |
| 296 contains a linkrev entry that can serve as a pointer to external | |
| 297 data. | |
| 298 | |
| 299 The revision data itself is a linear collection of data chunks. | |
| 300 Each chunk represents a revision and is usually represented as a | |
| 301 delta against the previous chunk. To bound lookup time, runs of | |
| 302 deltas are limited to about 2 times the length of the original | |
| 303 version data. This makes retrieval of a version proportional to | |
| 304 its size, or O(1) relative to the number of revisions. | |
| 305 | |
| 306 Both pieces of the revlog are written to in an append-only | |
| 307 fashion, which means we never need to rewrite a file to insert or | |
| 308 remove data, and can use some simple techniques to avoid the need | |
| 309 for locking while reading. | |
