tools: Introduce new client generic module vsh In order to share as much virsh' logic as possible with upcomming virt-admin client we need to split virsh logic into virsh specific and client generic features. Since majority of virsh methods should be generic enough to be used by other clients, it's much easier to rename virsh specific data to virshX than doing this vice versa. It moved generic virsh commands (including info and opts structures) to generic module vsh.c. Besides renaming methods and structures, this patch also involves introduction of a client specific control structure being referenced as private data in the original control structure, introduction of a new global vsh Initializer, which currently doesn't do much, but there is a potential for added functionality in the future. Lastly it introduced client hooks which are especially necessary during client connecting phase.

virt-admin: Tweak command parsing logic so that aliases point to new commands Change the logic in a way, so that VSH_CMD_FLAG_ALIAS behaves similarly to how VSH_OT_ALIAS for command options, i.e. there is no need for code duplication for the alias and the aliased command structures. Along with that change, switch any existing VSH_CMD_FLAG_ALIAS occurrences to this new format. Also, since this patch introduces a new command structure element, adjust the virsh-self-test test to make sure we won't ever miss to specify the '.alias' member for an aliased command because doing that would lead to an internal error.

tools: Make use of the correct environment variables Since commit 834c5720 which extracted the generic functionality out of virsh and made it available for other clients like virt-admin to make use of it, it also introduced a bug when it renamed the original VIRSH_ environment variables to VSH_ variables. Virt-admin of course suffers from the same bug, so this patch modifies the generic module vsh.c to construct the correct name for environment variables of each client from information it has.

Revert "admin: Rename virAdmConnect to virAdmDaemon" Commmit df8192aa introduced admin related rename and some minor (caused by automated approach, aka sed) and some more severe isues along with it. First reason to revert is the inconsistency with libvirt library. Although we deal with the daemon directly rather than with a specific hypervisor, we still do have a connection. That being said, contributors might get under the impression that AdmDaemonNew would spawn/start a new daemon (since it's admin API, why not...), or AdmDaemonClose would do the exact opposite or they might expect DaemonIsAlive report overall status of the daemon which definitely isn't the case. The second reason to revert this patch is renaming virt-admin client. The client tool does not necessarily have to reflect the names of the API's it's using in his internals. An example would be 's/vshAdmConnect/vshAdmDaemon' where noone can be certain of what the latter function really does. The former is quite expressive about some connection magic it performs, but the latter does not say anything, especially when vshAdmReconnect and vshAdmDisconnect were left untouched.

Since majority of virsh methods should be generic enough to be used by other clients, it's much easier to rename virsh specific data to virshX than doing this vice versa. It moved generic virsh commands (including info and opts structures) to generic module vsh.c. Besides renaming methods and structures, this patch also involves introduction of a client specific control structure being referenced as private data in the original control structure, introduction of a new global vsh Initializer, which currently doesn't do much, but there is a potential for added functionality in the future. Lastly it introduced client hooks which are especially necessary during client connecting phase.

#define VSH_EXCLUSIVE_OPTIONS_VAR(VARNAME1, VARNAME2) \
tools: Introduce new client generic module vsh In order to share as much virsh' logic as possible with upcomming virt-admin client we need to split virsh logic into virsh specific and client generic features. Since majority of virsh methods should be generic enough to be used by other clients, it's much easier to rename virsh specific data to virshX than doing this vice versa. It moved generic virsh commands (including info and opts structures) to generic module vsh.c. Besides renaming methods and structures, this patch also involves introduction of a client specific control structure being referenced as private data in the original control structure, introduction of a new global vsh Initializer, which currently doesn't do much, but there is a potential for added functionality in the future. Lastly it introduced client hooks which are especially necessary during client connecting phase.
