#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.

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)

Multiple revisions of a file works

  $ echo a >> foo

  $ hg commit -m 'modify foo'

  $ sqlite3 .hg/store/db.sqlite -init /dev/null << EOF

  > 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)
