revlog: implement a "default compression" mode
The revlog docker is now storing a default compression engine. When a chunk use
that compression, a dedicated mode is used in the revlog entry and we can
directly route it to the right decompressor.
We should probably make PLAIN and DEFAULT mode the only available mode for
revlogv2, but this is something for later.

#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 persistent-nodemap (rust !) revlog-compression-zstd (zstd !) 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 persistent-nodemap (rust !) revlog-compression-zstd (zstd !) 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 persistent-nodemap (rust !) revlog-compression-zstd (zstd !) 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 persistent-nodemap (rust !) revlog-compression-zstd (zstd !) 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 ..
