[Qemu-devel] [Bug 543478] Re: qemus pmemsave doesn't accept / in filename
Eh. Well. I'm a bit surprised that you won't allow forward slashes if you try to parse a path. It's actually a quite common character in the Linux world. Even other Unixes use it for separating components of a path. And since people use it so much, it should be as easy as possible to actually give a path to qemu. The excuse that it is used to create special expressions (which, btw?!) doesn't hold. I'm pretty confident that people use the '/' character to separate components of a path rather than doing special expressions. Especially when a path the a file is expected! So if there are still special expressions needed in a path, it'd be better to select a different character. Even if you don't agree on that, I really believe the user deserves some explanation along with the error message that is printed as I've pointed out in comment #0. ** Changed in: qemu-kvm (Ubuntu) Status: Invalid = New -- qemus pmemsave doesn't accept / in filename https://bugs.launchpad.net/bugs/543478 You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU.

[Qemu-devel] [Bug 543478] Re: qemus pmemsave doesn't accept / in filename
Note that putting quotes around the filename lets you use '/'. I.e. pmemsave 0x200 0x200 /tmp/abab I assume this is a shortcoming in the parser, as the source code at first glance claims to simply read a string. So I'm not sure how easily fixable it would be, but it appears to be something for upstream to consider (whether to fix needing to quote a filename, or add more precise help on error). ** Also affects: qemu Importance: Undecided Status: New -- qemus pmemsave doesn't accept / in filename https://bugs.launchpad.net/bugs/543478 You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU.
