7e6f58c0a9 Fix warnings with conversion of uuid.
More cleanup of uuid casting / structures is needed but for now just
cast like the rest of the code.

d3ce80e544 Add lvm2app interfaces to lookup a vgname from a pvid and pvname.
lvm2app forces applications to start with a volume group name,
open the volume group, then operate on individual pvs.  In some
cases the application may want to start with a device name rather
than the volume group name.  Today, if an application wants to
do this, it must iterate through all the volume groups to find
the volume group that the specific device is attached to.
These new interfaces allow the application to avoid such overhead.
Bump the lvm2app version number to 3.

ac24748b47 Add new --sysinit option for vgchange and lvchange.
A shortcut for --ignorelockingfailure, --ignoremonitoring, --poll n options
and LVM_SUPPRESS_LOCKING_FAILURE_MESSAGES environment variable used all at
once in initialisation scripts (e.g. rc.sysinit or initrd).

842a3664f0 Disable long living process flag in lvm2app.
This option should be configurable, but for now
do not set it at all.

(lvm2app is used in udisks probers and there
cac cause several nasty races when trying to update
lvmcache during rescan.)

c40380f72a Move error message to locking constructor and print
more descriptive message if locking fails instead of
"Locking type -1 initialisation failed."

Use read-only locking instead of misleading ignorelocking option
in message.

0148ff5ea2 Don't include lvm-version.h in exported liblvm file!
Move include of lvm-version.h into lvm_base.c where it belongs.

84ae15e8d1 Remove pv_t, vg_t & lv_t handles from lib. Only liblvm uses them.
Rename lvm.h to lvm2app.h for now.

6c91562aa9 Update lvm.h - remove remaining FIXMEs, note limitations of a few functions.
Almost done...

05762487ff Update return code for lvm_config_reload. 2009-07-27 21:02:35 +00:00

b2380fcc48 Add lvm_config_override - allow caller to override config, similar to --config.
Allowing the caller to override the LVM configuration with an API will
enable them to use things such as device filters.
While very flexible, there is some danger to this API in that it will
make it harder to debug setups that have a changing config and deduce
what might have happened.  At some point we may want to limit the scope
of this API but for now it is as open as the --config option to lvm commands.

Update exported symbols.  When I renamed lvm_reload_config to lvm_config_reload
I forgot to rename so I renamed that one here.

This I believe is the last liblvm API for now.  ;-)

5ec0df6fe1 Rename lvm_reload_config to lvm_config_reload.
The general naming scheme for most liblvm APIs is:
lvm_<object>_<action>

As there are likely to be other things to do on the lvm 'config' object
(i.e. lvm_config_set_device_filter), we should use consistent naming.

535c4372ca Update liblvm status return codes to be consistent.
For now, we use the following scheme.
For APIs that return an int, success is 0, fail is -1.
APIs that return handles, success is non-NULL, fail is NULL.
At this early stage, liblvm error handling mechanism is subject to change,
but for now we go with this simple scheme consistent with system
programming.

7b0fcd79a0 Add lvm_errno and lvm_errmsg to liblvm to obtain failure information.
Change create_toolcontext to still return an object if it fails part-way.
Add EUNCLASSIFIED (-1) as the default LVM errno code.

db0beacf02 Add default cmd->cmd_line initialization for liblvm lvm_create().
This needs initialized to non-NULL before using the archive() call.
Normally this is set to the cmdline string when lvm is called from a tool.
We could think about using it in another way, as a potential audit trail
of liblvm calls, or just leave it set to the default "liblvm", similar to
what clvmd does.  For now, just set it to "liblvm".

d95b544dfd Remove unnecessary includes in lvm_base.c.
We would like to declare our handles pv_t, vg_t, and lv_t in
the external library header lvm.h.  However, these are already
defined in metadata-exported.h for the use of some of the
in-progress liblvm APIs.  Thus, we cannot both define
them in lvm.h and include metadata-exported.h in the external
library C files.  We could use preprocessor tricks (#ifndef)
but for now we just avoid the include.

c190fc702e Add new liblvm build directory and move lvm_base.c.
The original liblvm.a has been moved to liblvm-internal.a.
We now use liblvm.a for the new application library and build
it inside liblvm directory.

Change dependencies so tools depend on liblvm application library,
and application library depends on liblvm internal.
