hgweb: support multi-level repository indexes by enabling descend and collapse
The descend option in hgweb can be used to display all reachable repositories
within a directory hierarchy if set to True. However, all reachable
repositories, regardless of their depth below the root of the hierarchy, are
then listed at the same level - expanded - in the hgweb interface. This patch
adds support for showing only each level of a directory hierarchy, with
subrepositories being shown alongside their parent repositories only at the
appropriate level (because there is no way to navigate to subrepositories from
within repositories), and the contents of directories hidden - collapsed -
behind a link for each directory. To enable this multi-level navigation, a new
option called collapse must be set to True when the descend option is set to
True.

187 the underlying revision storage object | |
188 | |
189 A revlog consists of two parts, an index and the revision data. | |
190 | |
191 The index is a file with a fixed record size containing | |
6912 | 192 information on each revision, including its nodeid (hash), the |
1083 | 193 nodeids of its parents, the position and offset of its data within |
194 the data file, and the revision it's based on. Finally, each entry | |
195 contains a linkrev entry that can serve as a pointer to external | |
196 data. | |
197 | |
198 The revision data itself is a linear collection of data chunks. | |
199 Each chunk represents a revision and is usually represented as a | |
200 delta against the previous chunk. To bound lookup time, runs of | |
201 deltas are limited to about 2 times the length of the original | |
202 version data. This makes retrieval of a version proportional to | |
203 its size, or O(1) relative to the number of revisions. | |
204 | |
205 Both pieces of the revlog are written to in an append-only | |
206 fashion, which means we never need to rewrite a file to insert or | |
207 remove data, and can use some simple techniques to avoid the need | |
208 for locking while reading. | |
