xtrabackup doesn't handle shell metacharacters

[Baron Schwartz]

This is xtrabackup 1.2:

[baron@ginger 5.1.41]$ xtrabackup --datadir=data --backup --target-dir=~/test-backup
... snip ....
xtrabackup: Error: cannot mkdir 2: ~/test-backup

It should make the backups in my home directory.

Baron,

tilde is not replaced with $HOME in C code. It should be done separately. If you need to use such paths, please try innobackupex - it works well there.

Valentine,

It looks like a valid feature request to me. You are right, tilde expansion is performed by the shell. But many programs do that too.

For example:

$ dd if=/dev/zero of=~/tmp_file count=1
1+0 records in
1+0 records out
512 bytes transferred in 0.000056 secs (9138228 bytes/sec)

$ dd if=~/tmp_file of=/dev/null
1+0 records in
1+0 records out
512 bytes transferred in 0.000025 secs (20648881 bytes/sec)

See also "man 3 glob".
