189 the underlying revision storage object | |
190 | |
191 A revlog consists of two parts, an index and the revision data. | |
192 | |
193 The index is a file with a fixed record size containing | |
6912 | 194 information on each revision, including its nodeid (hash), the |
1083 | 195 nodeids of its parents, the position and offset of its data within |
196 the data file, and the revision it's based on. Finally, each entry | |
197 contains a linkrev entry that can serve as a pointer to external | |
198 data. | |
199 | |
200 The revision data itself is a linear collection of data chunks. | |
201 Each chunk represents a revision and is usually represented as a | |
202 delta against the previous chunk. To bound lookup time, runs of | |
203 deltas are limited to about 2 times the length of the original | |
204 version data. This makes retrieval of a version proportional to | |
205 its size, or O(1) relative to the number of revisions. | |
206 | |
207 Both pieces of the revlog are written to in an append-only | |
208 fashion, which means we never need to rewrite a file to insert or | |
209 remove data, and can use some simple techniques to avoid the need | |
210 for locking while reading. | |
