upgrade: implement partial upgrade for upgrading persistent-nodemap
Upgrading repositories to use persistent nodemap should be fast and easy as it
requires only two things:
1) Updating the requirements
2) Writing a persistent-nodemap on disk
For both of the steps above, we don't need to edit existing revlogs.
This patch makes upgrade only do the above mentioned two steps if we are
only upgarding to use persistent-nodemap feature.
Since `nodemap.persist_nodemap()` assumes that there exists a nodemap file for
the given revlog if we are trying to call it, this patch adds `force` argument
to create a file if does not exist which is true in our upgrade case.
The test changes demonstrate that we no longer write nodemap files for manifest
after upgrade which I think is desirable.

#require sqlite no-chg The sqlitestore backend leaves transactions around when used with chg. Since this backend is primarily intended as proof-of-concept for alternative storage backends, disable it for chg test runs to avoid the instability. $ cat >> $HGRCPATH <<EOF > [extensions] > sqlitestore = > EOF New repo should not use SQLite by default $ hg init empty-no-sqlite $ cat empty-no-sqlite/.hg/requires dotencode fncache generaldelta revlogv1 sparserevlog store storage.new-repo-backend=sqlite is recognized $ hg --config storage.new-repo-backend=sqlite init empty-sqlite $ cat empty-sqlite/.hg/requires dotencode exp-sqlite-001 exp-sqlite-comp-001=zstd (zstd !) exp-sqlite-comp-001=$BUNDLE2_COMPRESSIONS$ (no-zstd !) fncache generaldelta revlogv1 sparserevlog store $ cat >> $HGRCPATH << EOF > [storage] > new-repo-backend = sqlite > EOF Can force compression to zlib $ hg --config storage.sqlite.compression=zlib init empty-zlib $ cat empty-zlib/.hg/requires dotencode exp-sqlite-001 exp-sqlite-comp-001=$BUNDLE2_COMPRESSIONS$ fncache generaldelta revlogv1 sparserevlog store Can force compression to none $ hg --config storage.sqlite.compression=none init empty-none $ cat empty-none/.hg/requires dotencode exp-sqlite-001 exp-sqlite-comp-001=none fncache generaldelta revlogv1 sparserevlog store Can make a local commit $ hg init local-commit $ cd local-commit $ echo 0 > foo $ hg commit -A -m initial adding foo That results in a row being inserted into various tables $ sqlite3 .hg/store/db.sqlite -init /dev/null << EOF > SELECT * FROM filepath; > EOF 1|foo $ sqlite3 .hg/store/db.sqlite -init /dev/null << EOF > SELECT * FROM fileindex; > EOF 1|1|0|-1|-1|0|0|1||6/\xef(L\xe2\xca\x02\xae\xcc\x8d\xe6\xd5\xe8\xa1\xc3\xaf\x05V\xfe (esc) $ sqlite3 .hg/store/db.sqlite -init /dev/null << EOF > SELECT * FROM delta; > EOF 1|1| \xd2\xaf\x8d\xd2"\x01\xdd\x8dH\xe5\xdc\xfc\xae\xd2\x81\xff\x94"\xc7|0 (esc) Tracking multiple files works $ echo 1 > bar $ hg commit -A -m 'add bar' adding bar $ sqlite3 .hg/store/db.sqlite -init /dev/null << EOF > SELECT * FROM filedata ORDER BY id ASC; > EOF 1|1|foo|0|6/\xef(L\xe2\xca\x02\xae\xcc\x8d\xe6\xd5\xe8\xa1\xc3\xaf\x05V\xfe|-1|-1|0|0|1| (esc) 2|2|bar|0|\xb8\xe0/d3s\x80!\xa0e\xf9Au\xc7\xcd#\xdb_\x05\xbe|-1|-1|1|0|2| (esc) Multiple revisions of a file works $ echo a >> foo $ hg commit -m 'modify foo' $ sqlite3 .hg/store/db.sqlite -init /dev/null << EOF > SELECT * FROM filedata ORDER BY id ASC; > EOF 1|1|foo|0|6/\xef(L\xe2\xca\x02\xae\xcc\x8d\xe6\xd5\xe8\xa1\xc3\xaf\x05V\xfe|-1|-1|0|0|1| (esc) 2|2|bar|0|\xb8\xe0/d3s\x80!\xa0e\xf9Au\xc7\xcd#\xdb_\x05\xbe|-1|-1|1|0|2| (esc) 3|1|foo|1|\xdd\xb3V\xcd\xde1p@\xf7\x8e\x90\xb8*\x8b,\xe9\x0e\xd6j+|0|-1|2|0|3|1 (esc) $ cd ..
