emitrevision: if we need to compute a delta on the fly, try p1 or p2 first
Falling back to `prev` does not yield any real value on modern storage and
result in pathological changes to be created on the other side. Doing a delta
against a parent will likely be smaller (helping the network) and will be safer
to apply on the client (helping future pulls by Triggering intermediate
snapshop where they will be needed by later deltas).

#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 $ hg debugrequires -R empty-no-sqlite dotencode dirstate-v2 (dirstate-v2 !) fncache generaldelta persistent-nodemap (rust !) revlog-compression-zstd (zstd !) revlogv1 share-safe sparserevlog store storage.new-repo-backend=sqlite is recognized $ hg --config storage.new-repo-backend=sqlite init empty-sqlite $ hg debugrequires -R empty-sqlite dotencode dirstate-v2 (dirstate-v2 !) exp-sqlite-001 exp-sqlite-comp-001=zstd (zstd !) exp-sqlite-comp-001=$BUNDLE2_COMPRESSIONS$ (no-zstd !) fncache generaldelta persistent-nodemap (rust !) revlog-compression-zstd (zstd !) revlogv1 share-safe 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 $ hg debugrequires -R empty-zlib dotencode dirstate-v2 (dirstate-v2 !) exp-sqlite-001 exp-sqlite-comp-001=$BUNDLE2_COMPRESSIONS$ fncache generaldelta persistent-nodemap (rust !) revlog-compression-zstd (zstd !) revlogv1 share-safe sparserevlog store Can force compression to none $ hg --config storage.sqlite.compression=none init empty-none $ hg debugrequires -R empty-none dotencode dirstate-v2 (dirstate-v2 !) exp-sqlite-001 exp-sqlite-comp-001=none fncache generaldelta persistent-nodemap (rust !) revlog-compression-zstd (zstd !) revlogv1 share-safe 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 ..
