extensions: imp module is removed in Python 3.12 - use importlib to load files
imp has been deprecated for a long time, and has finally been removed in Python
3.12 .
imp was only used for loading extensions that has been specified with direct
.py path or path to a package directory. The same use cases can be achieved
quite simple with importlib, , possiby with small changes in corner cases with
undefined behaviour, such as extensions without .py source.
There might also be corner cases and undefined behaviour around use of
sys.modules and reloading.

247 the underlying revision storage object | |
248 | |
249 A revlog consists of two parts, an index and the revision data. | |
250 | |
251 The index is a file with a fixed record size containing | |
6912 | 252 information on each revision, including its nodeid (hash), the |
1083 | 253 nodeids of its parents, the position and offset of its data within |
254 the data file, and the revision it's based on. Finally, each entry | |
255 contains a linkrev entry that can serve as a pointer to external | |
256 data. | |
257 | |
258 The revision data itself is a linear collection of data chunks. | |
259 Each chunk represents a revision and is usually represented as a | |
260 delta against the previous chunk. To bound lookup time, runs of | |
261 deltas are limited to about 2 times the length of the original | |
262 version data. This makes retrieval of a version proportional to | |
263 its size, or O(1) relative to the number of revisions. | |
264 | |
265 Both pieces of the revlog are written to in an append-only | |
266 fashion, which means we never need to rewrite a file to insert or | |
267 remove data, and can use some simple techniques to avoid the need | |
268 for locking while reading. | |
