persistent-nodemap: respect the mmap setting when refreshing data
After writing updated data, we reload the in-memory data. However, that logic
was… wrong. We were doing file read when mmap was requested and when the
configuration was requesting to not use mmap… we were using it.
This should now be fine.
Just exercise debugindexdot
Create a short file history including a merge.
$ hg init t
$ cd t
$ echo a > a
$ hg ci -qAm t1 -d '0 0'
$ echo a >> a
$ hg ci -m t2 -d '1 0'
$ hg up -qC 0
$ echo b >> a
$ hg ci -m t3 -d '2 0'
created new head
$ HGMERGE=true hg merge -q
$ hg ci -m merge -d '3 0'
$ hg debugindexdot -c
digraph G {
-1 -> 0
0 -> 1
0 -> 2
2 -> 3
1 -> 3
}
$ hg debugindexdot -m
digraph G {
-1 -> 0
0 -> 1
0 -> 2
2 -> 3
1 -> 3
}
$ hg debugindexdot a
digraph G {
-1 -> 0
0 -> 1
0 -> 2
