Hello,
This simple script:
pragma journal_mode=wal;
CREATE TABLE IF NOT EXISTS sessions (
sid varchar(32) primary key not null
);
begin;
INSERT OR REPLACE INTO sessions values('0123456789abcdef0123456789abcde1');
-- There it fails after insert or replace before commit
commit;
Fails on Cygwin and passess without problems using
windows builds.
With normal build the script reports
unable to open database file
While building with -DSQLITE_DEBUG
it reports an assertion:
assertion "isExclusive==0 || isCreate" failed: file "sqlite3.c", line 34058,
function: winOpen
(Version 3.7.8)
This does not happen on Windows builds of the same sources.
I've attached the script and VDBE traces under cygwin and windows builds.
Cygwin version: 1.7.9(0.237/5/3)
