SQLite is quite strict with the filesystem, and it needs it to work as
advertised, for example with syncing and file locking. VirtualBox is
just not there yet. Go bug them. Give them a tiny test case, a
sequence of commands to create a repository and try to open it.
Actually, I just reproduced it here using Oracle VirtualBox 4.3.12
r93733 running on 64-bit Windows 7 (Pro, as if that matters). Just
include this email in your report. Here's the sequence:
1. Download Fossil version 1.29 to the host desktop.
2. Unpack the archive to get fossil.exe.
3. Start cmd.exe, cd to desktop, and run "fossil new crash.fossil".
4. Start a guest OS (using Slackware64 14.1) in VirtualBox.
5. Install Fossil in the guest OS using any method.
6. Mount the desktop via a VirtualBox share, e.g. to /mnt.
7. Run "fossil open /mnt/crash.fossil".
Error message is:
SQLITE_IOERR: os_unix.c:29821: (22)
fsync(/mnt/crash.fossil-mj698EA9932) - Invalid argument
fossil: disk I/O error: {COMMIT}
(line number may vary since I'm using Fossil 2e51be8ec2 in the guest)
Here's the failing function. The error is printed on line 29821, which
says unixLogError(SQLITE_IOERR_DELETE, "fsync", zPath). Perhaps you
could try recompiling Fossil with SQLITE_DISABLE_DIRSYNC, though I'm
sure you will have other problems, e.g. database corruption.
/*
** Delete the file at zPath. If the dirSync argument is true, fsync()
** the directory after deleting the file.

static int unixDelete(
sqlite3_vfs *NotUsed, /* VFS containing this as the xDelete
method */
const char *zPath, /* Name of file to be deleted */
int dirSync /* If true, fsync() directory after
deleting file */
){
int rc = SQLITE_OK;
UNUSED_PARAMETER(NotUsed);
SimulateIOError(return SQLITE_IOERR_DELETE);
if( osUnlink(zPath)==(-1) ){
if( errno==ENOENT ){
rc = SQLITE_IOERR_DELETE_NOENT;
}else{
rc = unixLogError(SQLITE_IOERR_DELETE, "unlink", zPath);
}
return rc;
