Bug#661575: lsof on Hurd
tag 661575 +help forwarded 661575 a...@purdue.edu thanks Abe, Thanks again for your work on lsof. There seems to be no support in the lsof code for the Hurd operating system. I cannot say I am surprised but it does I believe meet your criteria for support as it is readily available for download and installation as per http://www.debian.org/ports/hurd/ . I have copied the Debian Hurd mailing list as they are most likely to be able to provide patches and advice. Thanks.

That would have to be added first... Samuel -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe. Trouble? Contact listmas...@lists.debian.org

I guess I should have copied an upstream Hurd mailing list as well. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

Of course, but that doesn't change the actual issue: I don't think there is any interface to actually implement /proc/*/fd either. I guess I should have copied an upstream Hurd mailing list as well. It does not matter very much actually: most upstream Hurd people are also subscribed to debian-hurd.

Isn't there some bit of purest thinking that we have no right to assume that a file descripter actually implies a physical file, hence the question just cannot be asked. If that is so then the best Hurd might ever be able to offer lsof is the current /proc file system. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

There were past proposals about this, but I don't have a pointer. Thanks, Roland -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

Nicholas, You write: Thanks again for your work on lsof. There seems to be no support in the lsof code for the Hurd operating system.

I have copied the Debian Hurd mailing list as they are most likely to be able to provide patches and advice. Thanks. Nicholas Thanks for the inquiry. I am now 8 years into retirement and have reduced lsof work to the minimum necessary to support a few remaining dialects, including mainstream Linux. As a result I'm not inclined to take on a new port. Since the lsof sources are open software with just a few restrictions imposed by the Purdue copyright, it would be permissible for someone else to do the Hurd port.

Isn't there some bit of purest thinking that we have no right to assume that a file descripter actually implies a physical file, hence the question just cannot be asked. There is sense in that, yes. That can also happen on Linux actually, when the file is removed. The best you can have is what path was used to open it. In the Hurd, only the process itself knows. If that is so then the best Hurd might ever be able to offer lsof is the current /proc file system. The process can be asked for the path. It just has to avoid throwing it away after opening it, and define an interface to fetch it.
