I was trying to serialize and then restore database, all I get when trying to call scan on restored database is hyperscan.InvalidError: error code -1. I'm using python module version 0.7.7 and python 3.11.9.
Here's sample code:
db = hyperscan.Database(mode=hyperscan.HS_MODE_BLOCK)
db.compile(
expressions=[b'bar']
)
def callback(id, start, end, flags, context):
print(f"Matched {id} from {start} to {end}")
db.scan(b'foo bar baz', callback)
data = hyperscan.dumpb(db)
db2 = hyperscan.loadb(data, hyperscan.HS_MODE_BLOCK)
db2.scan(b'foo bar baz', callback)
And results:
data = hyperscan.dumpb(db)
db2 = hyperscan.loadb(data, hyperscan.HS_MODE_BLOCK)
> db2.scan(b'foo bar baz', callback)
E hyperscan.InvalidError: error code -1
I also noticed in debugger that restored db has no scratch atribute set (it's None), but I'm not sure if this is the reason.
