Subject: Make sure .qch file is opened read-only
X-Git-Tag: accepted/tizen/20131212.181521~7^2~10

Make sure .qch file is opened read-only

So far qsqlite tried to open the file first read/write, and falling back
to read access only if this fails. This has resulted in excessively long
loading times e.g. on Windows XP.
