0bf8455b64 Rename liblvm to liblvm-internal. 
Make preparation for using liblvm for new application library.
 2009-03-06 16:17:28 +00:00
Thomas Woerner
5f4b7a2644 Added files lib/lvm.h and lib/lvm_base.c: 
New structure lvm (used as an alias to cmd_context), new type definition lvm_t
for the lvm handle. Added functions lvm_create, lvm_destroy and
lvm_reload_config using the new handle.

Modified test/api/test.c:
Use new lvm.h header file and lvm_t handle.

Removed lib/lvm2.h

8ef2b021ed Default stripesize 64k & config file setting for it;

introducing too many new bugs:-)  (Same exercise required for other archs.)

349f09e401 o _build_name was allocating 1 byte too few, which meant the 
terminating zero was falling off at some later point.

o Don't try and iterate from a deleted node in _prune_unmarked.

Joe Thornber
7d68b08028 o First changes to add snapshot support. 
I'm taking a different route from LVM1 here in that snapshots are a
seperate entity from the logical volumes, I think of them as an
application of an LV (or two lvs rather).  As such there is a list of
snapshots held against the vg, and there is *not* a SNAPSHOT, or
SHAPSHOT_ORG flag in lv->status.

6d52fb460b o Split activate.c into a high level (remaining in activate.c) and low level (ll-activate.[hc]) API.

6036e5e0f7 o split the uuid -> device map out from vgcache 
o  roll vgcache back to agk's implementation, we'll revisit this as part
   of the cluster integration.

faa556e759 Add internal cache holding a 'hint' list of the PVs belonging to each VG. 
A substantial speed-up - particularly in readline mode.
If the hints turn out to be wrong, the relevant parts get thrown away.
vgscan destroys it totally.  In both cases it then rebuilds itself as
required.

0bab65915d o Sync up todays work on converting to the segmented representation of 
logical volumes.  It includes:

   format1 changes.

   metadata.h changes.

   lv_manip.c changed (striped allocation still not done though).

   activate.c changes.

Nothing has been near a compiler as yet.

Alasdair can you look at changing display.c to use to output the mappings
in a more segment oriented format please ?

I haven't put the span list into struct physical_volume to represent allocated
extents.  I think the burden of maintaining it for things like lv_extend may
out weigh it's uses.

12eabe3031 o composite filter that allows us to merge filters. Think of it as &&'ing 
filters in order.

eg,

	f = composite_filter_create(2, regex_filter, persistent_filter);

  ownership of the filters passes, they will be destroyed when f's
  destroy method is called.
 2001-10-22 14:39:12 +00:00
Joe Thornber
5f16718b19 o Filter which caches valid devices in a file. Pass in init == 1 to the 
constructor if you want it to ignore the existing cache and check every
  device again (eg, vgscan, pvscan).

c4151d1aa4 reinstate a removed line 2001-10-22 13:44:09 +00:00

291ec3b6c0 o Filter for the dev cache that takes values from config file: 
devices {

        # first match is final, eg.  /dev/ide/cdrom
		        # get's rejected due to the first pattern

					filter=["r/cdrom/",         # don't touch the music !
							"a/hd[a-d][0-9]+/",
							"a/ide/",
							"a/sd/",
							"a/md/",
							"a|loop/[0-9]+|", # accept devfs style loop back
							"r/loop/",        # and reject old style
							"a/dasd/",
							"a/dac960/",
							"a/nbd/",
							"a/ida/",
							"a/cciss/",
							"a/ubd/",
							"r/.*/"] # reject all others
}


Alasdair this is ready to roll into the tools now.

d1b28647ed o First pass at the regex code. lib/regex/matcher takes an array of regex's 
and builds a *very* efficient engine that will tell you which regex a string
  matches with only a single pass through the string.  To be used in the config
  file when specifying devices.

o Anchor's aren't supported yet (^ and $) but that won't take long.

o Also when we get some realistic config files we may want to consider adding an
  extra level of indirection to the dfa state in order to compress the table.
  It all depends on how large typical tables get.
