|
275 | 279 | A revlog consists of two parts, an index and the revision data. |
|
276 | 280 | |
|
277 | 281 | The index is a file with a fixed record size containing |
|
278 | 282 | information on each revision, includings its nodeid (hash), the |
|
279 | 283 | nodeids of its parents, the position and offset of its data within |
|
280 | 284 | the data file, and the revision it's based on. Finally, each entry |
|
281 | 285 | contains a linkrev entry that can serve as a pointer to external |
|
282 | 286 | data. |
|
283 | 287 | |
|
284 | 288 | The revision data itself is a linear collection of data chunks. |
|
285 | 289 | Each chunk represents a revision and is usually represented as a |
|
286 | 290 | delta against the previous chunk. To bound lookup time, runs of |
|
287 | 291 | deltas are limited to about 2 times the length of the original |
|
288 | 292 | version data. This makes retrieval of a version proportional to |
|
289 | 293 | its size, or O(1) relative to the number of revisions. |
|
290 | 294 | |
|
291 | 295 | Both pieces of the revlog are written to in an append-only |
|
292 | 296 | fashion, which means we never need to rewrite a file to insert or |
|
293 | 297 | remove data, and can use some simple techniques to avoid the need |
