*	Open up libzfs_run_process/libzfs_load_module	Brian Behlendorf	2011-01-28	1	-0/+6
\| \| \| \| \| \| \|	Recently helper functions were added to libzfs_util to load a kernel module or execute a process. Initially this functionality was limited to libzfs but it has become clear there will be other consumers. This change opens up the interface so it may be used where appropriate.
*	Add helper functions for manipulating device names	Ned Bass	2010-10-22	1	-0/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	This change adds two helper functions for working with vdev names and paths. zfs_resolve_shortname() resolves a shorthand vdev name to an absolute path of a file in /dev, /dev/disk/by-id, /dev/disk/by-label, /dev/disk/by-path, /dev/disk/by-uuid, /dev/disk/zpool. This was previously done only in the function is_shorthand_path(), but we need a general helper function to implement shorthand names for additional zpool subcommands like remove. is_shorthand_path() is accordingly updated to call the helper function. There is a minor change in the way zfs_resolve_shortname() tests if a file exists. is_shorthand_path() effectively used open() and stat64() to test for file existence, since its scope includes testing if a device is a whole disk and collecting file status information. zfs_resolve_shortname(), on the other hand, only uses access() to test for existence and leaves it to the caller to perform any additional file operations. This seemed like the most general and lightweight approach, and still preserves the semantics of is_shorthand_path(). zfs_append_partition() appends a partition suffix to a device path. This should be used to generate the name of a whole disk as it is stored in the vdev label. The user-visible names of whole disks do not contain the partition information, while the name in the vdev label does. The code was lifted from the function make_disks(), which now just calls the helper function. Again, having a helper function to do this supports general handling of shorthand names in the user interface. Signed-off-by: Brian Behlendorf <[email protected]>
*	Support custom build directories and move includes	Brian Behlendorf	2010-09-08	1	-0/+716
	One of the neat tricks an autoconf style project is capable of is allow configurion/building in a directory other than the source directory. The major advantage to this is that you can build the project various different ways while making changes in a single source tree. For example, this project is designed to work on various different Linux distributions each of which work slightly differently. This means that changes need to verified on each of those supported distributions perferably before the change is committed to the public git repo. Using nfs and custom build directories makes this much easier. I now have a single source tree in nfs mounted on several different systems each running a supported distribution. When I make a change to the source base I suspect may break things I can concurrently build from the same source on all the systems each in their own subdirectory. wget -c http://github.com/downloads/behlendorf/zfs/zfs-x.y.z.tar.gz tar -xzf zfs-x.y.z.tar.gz cd zfs-x-y-z ------------------------- run concurrently ---------------------- <ubuntu system> <fedora system> <debian system> <rhel6 system> mkdir ubuntu mkdir fedora mkdir debian mkdir rhel6 cd ubuntu cd fedora cd debian cd rhel6 ../configure ../configure ../configure ../configure make make make make make check make check make check make check This change also moves many of the include headers from individual incude/sys directories under the modules directory in to a single top level include directory. This has the advantage of making the build rules cleaner and logically it makes a bit more sense.
