[sqlite] journal files not always removed

Okay let's restart... maybe I misunderstood that Richard was able to reproduce this. I have figured out a simple script that with 3.8.11.1 windows (using binary download sqlite3.exe) causes the problem. running just 'sqlite3.exe' --- script --- .open test.db pragma journal_mode=wal; .open

Checked this on WIndows 7 & 8, works as expected. This means either Windows 10 has some glitch or the access level to the folder is not correct, files may not be deleted by that process or some antivirus is checking the file while SQLite is trying to delete it, or you are not closing the DB

Hello, I've recently found SQLite doesn't always remove its journal files anymore. The issue seems to occur when opening WAL databases in read-only mode (i.e. using SQLITE_OPEN_READONLY). A scenario to reproduce this (using version 3.8.11.1) looks like: 1. open a WAL database in read-only

What do you want to see in journal files? You can execute 'PRAGMA journal_mode = persist' and all information in journal file except first 4 bytes will be left on disk for you. Is it enough? Pavel On Tue, Feb 2, 2010 at 7:00 AM, rishabh wrote: > > hey, > > I am coding

I'm working with version 3.5.2 under Linux. I've got a database that is being shared between two processes and I'm running into issues with the journal file that doesn't go away. When that happens, one process appears to have the lock on the database and the other process is essentially locked

Hi All, The journal files created during the transactions are not getting deleted. These files are created per transaction or only one file per connection? I am seeing hundreds of journal files with a '-' suffix causing an error "Database disk full" (DB file is stored in flash card).

[sqlite] journal files and database corruption

In the article about locking and concurrency on the SQLite website, where it talks about how to corrupt a SQLite database, it says that a SQLite database can be corrupted if a hot journal file is missing when SQLite reconnects to the database. What kind of corruption are we talking about,
