Merged robust security code into Orange-Branch.

Added pvfs2-join.c under src/apps/admin dir.

Merged in changes from Orange-Branch. There were a number of bugs fixed there since this branch was created.

Next round of distributed directory changes.

incorporate dist-dir-struct to the source tree. It's compilable but not runnable. still have a lot to change and add. Commit as a touch base.

merging Orange Branch changes in

Pass multiple dirent handles between server and client.

initial merge with Orange-Branch. much will be broken

lots of little fixes that have been in the works for a while

Preliminary work for distributed directories - making client aware of DIR_ENT_KEY.

merge of B2O-Blue-Sync,HEAD,and latest of Orange.

commiting changes from merge of Orange and Blue into test branch.

*** empty log message ***

merge from HEAD: http://www.pvfs.org/fisheye/changelog/PVFS/?cs=MAIN:pcarns:20090727185444

Merge of Orange-Branch, Orange-FailOver-Becky, and version 1.164 of sys-io.sm (do not unstuff on a read).
This version of Orange-FailOver-Becky supports failover for large files only.  The next iteration will
support small-io failover.

merged in changes from summer at LANL

patches from Dries Kimpe:
- Added check before redefining USE_GNU in pvfs2-server.c
- Made use of endecode_fields_xxx macro's consistent and solved warning
in case they were compiled out.  The macro should be used as a function
call, and thus have a semicolumn at the end.

Completed most of the getattr changes.  Not all done just yet.

Completed changes to PVFS_object_attr.  Changes to get-attr.sm are still underday

- Removed max3 macro and defined max() macro and used max(max(a,b), c)
  for extra_size_PVFS_object_attr definition
- Redefined PVFS_REQ_LIMIT_LISTATTR to 113 which is the largest set that fits in the
  1MB preallocated space.
- Redefined pvfs2-ls.c: MAX_NUM_DIRENTS to 113 to match PVFS_REQ_LIMIT_LISTATTR.
- Trac Ticket #70

reverse merge from HEAD.

reverse merge of changes to HEAD since branch.  Includes small file changes.

Merging small files branch to head.  Includes server side precreation of
data files and file stuffing.

Reverse merged and ported to HEAD.

Comment update, bugfix for encoding size allocation.

Updated encode/decode buffers.  Updated getattr permission checking.

Updated capability encode/decode.  Fixed capability transmission across the wire...currently asks for a capability with every getattr and gives one back as well.

Add unstuffed mask to static mask set.  Once a file has been unstuffed it
never goes back, and we need this flag to stay in sync with datafiles that
are placed in the static acache.  This fixes the fsx failure in the
small-files-branch.

Updated encode/decode to handle variable length keys.  Added init/dup/free to security module for capabilities, added capability to the object attributes structure with associated encode/decode.  Code in get-attr state machine is commented out, just a placeholder for now.

added PVFS_capability to server request/response but without endecode

Added a PVFS_ATTR mask for capability requests

merge acache changes to 2.7 branch.

merging acache split and bug fixes from trunk

Split underpinnings of acache into two parts:
- cache for attr fields that are static once set (dist, dfiles, and type)
- cache for attr fields that can be changed by users (uid, perms, etc.)
The former has a much longer default timeout of 6 minutes, and captures all
of the attribute fields needed by sys-io.sm.

fix protocol padding issue pointed out by pw

encode stuffed_size in protocol for getattr, make sys-getattr honor the
stuffed_size when possible, increment protocol version number because we are
no longer wire compatible with trunk

inverted the STUFFED_SIZE flag and renamed it UNSTUFFED.  It is now a marker
to indicate that a file is not stuffed

fixes to non stuffed create.

Big pile-o' changes to make Pete go mad.

The main changes are the implementation of the stuffed create path (now just the create state machine and operation), and the beginnings of the "unstuff" operation.

This also includes the request scheduler and state machine cleanups (required for using prelude with batch_remove) and whatever else I may have happened to change along the way.

This code is able to create files, but writing to them is almost guaranteed to break.

Update migration branch to current CVS version

Upgrade to current CVS version

reverse merge of HEAD to WALT3 branch.

- Support for immutable files
- Cleanups in the pvfs2-bufmap interfaces (replace int with size_t)
- Utility for displaying extended attributes and setting them
- Support for disabling atime updates at the object level, file system level (mount time)
  and directories.

Modified parent handle reference for datafiles behavior.
Also allow client to get parent handle in getattr sm.

Merge HEAD into Walt's branch.
Rework new state machines to the new cleanups introduced by Walt.

Modification for migration added, some functions still need to be adapted after moving to a new branch...

Added request statistics to scheduler, reference from datafiles to
parent metafile (needed for migration) and auto migration tool(unfinished).

reverse merge from trunk.  working for now.

Reverse merge changes from HEAD to posix-extensions-branch.

Patch fixes the atime, mtime and ctime problems that people have
reported with PVFS2.
Patch changes the notion of who sets these times. Earlier behavior was the
clients providing the times to the server. New behavior is to have the
server set these times except in  the implementation of utimes() system
call whereby clients explicitly set the time (atime and mtime).
NOTE: We dont allow the clients to dictate the ctime setting at all since
that is consistent with all file systems.
So what we have is:
read, readdir -> atime update required
write, truncate -> mtime update required
ctime is updated on every setattr implicitly on the server.

Since there is no need for parent_*time fields in the server request for chdirent,
crdirent and rmdirent, the next step is to remove those fields, fix the endecode
macros and bump up the major version of the protocol.

Patch also implements these times lazily by flushing them only at the time
of a close rather than after every read/write which could be pretty
expensive.

merge of murali's changes from trunk.

[pcarns]: Patch to allow modifying distribution, distribution parameters and number of
data files to use within a given directory. Such setting will only impact creation of future files
within the same directory. It does not change existing files' parameters. All such hints
are inherited by newly created directories as well..
[pcarns]: Allow trove to continue to read a list of xattrs/keyvals
without stopping if some subset of keys dont exist in the keyval db. Modifies the keyval_read_list() function
to return an array of completely independant error codes for each key that is read.
[pcarns]: adjust encode_string() macro to make it safe to call on NULL strings
[pcarns]: bug in the getattr state machine that would cause it to read dirent_count most of the time
regardless of whether the attribute mask requested it or not.
[slang]: fix a couple of bugs in the get-attr server-side state machine whereby the dirent_count was being read
using the dirent handle instead of the dirdata handle. Fixed a return value from dbpf_keyval_get_handle_info_op_svc
so that get-attr would not needlessly hang..
[vilayann]: fixes for the viewdist utility yet again, since the keys for the xattrs have changed...

[pcarns]: add protocol versioning to PVFS2.  Major version changes are
incompatible up or down.  New clients can't talk to old servers, but new
servers can talk to old clients.

updates to my event changes to bring them inline with trunk

merged acache changes to trunk.

more acache updates.

intermediate commit of acache changes to branch.

[pcarns]: Corrects the maximum size calculation for request messages that
include attribute structures.  An attrib structure can never simultaneously
hold information for both a symlink and a metafile, but it was reserving enough
memory to do so.

[pcarns]: "This adds a new directory attribute field that indicates how many
entries (of any type) are in a given directory.  The server already had the
ability to gather this information, but it just wasn't being reported.   A
client can read this with getattr(), but it can't be modified directly."

Updates for distribution renamings.

Update for rename of PVFS_Dist to PINT_dist.

remove spurious yet harmless semicolon

smarter compiler caught a potential macro expansion bug

add encoding rules for most request and response messages

started making progress toward getting symlink support.  got sidetracked
along the way trying to work out an easy method to unify sys-create,
sys-symlink, and sys-mkdir all at once.  create should work as normal, but
the rest of the changes shouldn't affect functionality (i.e. symlink doesn't
remotely work, sys-mkdir, isn't there yet).

redfined attribute values to make a bit more sense at a quick glance.
bumped up pvfs2-version.  started adding required things for symlinks

client-side remove state machine can remove datafiles now too.

discarded some unused extended attribute structures

more attribute cleanup

cleaned up the metafile attributes structure

small cleanups, got rid of a "pint-*" include in attributes header

next phase of attribute cleanup:
- added mask field to obj attribute structure
- remove seperate mask value from pinode struct and several functions,
  including sysint functions
- made server store mask value properly and report it back- even though it
  still ignores which mask fields are set in getattr and setattr requests
- for now, made it so that number of datafiles _cannot_ be specified at
  sys_create time by setting fields in the attributes structure directly.
  Until this issue is resolved, there is currently no way to pick the
  number of datafiles at create time- it is always chosen by system.
- misc. other related cleanup

big nasty commit: converted all of the attribute masks to new
style, as found in pvfs2-types.h.  This required changing a
lot of code, most significantly in the pinode cache / pinode
helper area.  Also got rid of a pinode helper function that was
rendered unecessary after the attribute modifications.

System interface tests appear to behave just like before...

Things still aren't right, though!  But I think it will work at
least as well as before the commit, and is slightly more consistent.
Things that are still off:
- the mask should be stored inside the attributes structure,
  rather than kept in a seperate variable everywhere
- server currently ignores attribute masks entirely and does its
  own thing
- a lot of the client code, in particular getattr.c and the pinode
  helper/cache, make big assumptions about how attributes and
  masks can be handled.  In a lot of places they are just copied
  around as atomic units regardless of mask, for example.

I had to stop changing stuff somewhere...

changed objtype field in attributes to be of type PVFS_ds_type instead
of an integer; corrected many places in the code where attribute mask
values were being used as object type values - the object type is now
always one of PVFS_TYPE_XXX.

whoops- some of the old attribute mask values collided with new values
I added recently.  For now this fixes the recent problem with bogus
attributes after lookup in PVFS_sys_{read/write}.

got rid of the U_READ,U_WRITE, etc. family of #defines and replaced with
PVFS_U_READ,PVFS_U_WRITE, etc.

got rid of PVFS_count32 type; replaced with int32_t or uint32_t or int
where appropriate

got rid of PVFS_string type and replaced with char* everywhere

step one of header cleanup: ran pvfs2-mangle-in-place-80col.sh on these
files to get the code format closer to standard

Removed unused field from datafile attributes.

added a field to the metadata attrributes that tells how big the
distribution is

Added defines for the various PVFS object types in pvfs2-storage.h, made sure they are used in pvfs2-attr.h as well.  Should deprecate the defines in pvfs2-attr.h eventually.

dist needed to be a pointer, duh

added the distribution field back to the metadata object

start defining a PVFS_directory_attr_s struct

added in job code; added in request processor code where empty
files were accidentally checked in last time

added request scheduler and request protocol headers into new tree
