pvfs2-ls.c

scripts etc. that use pvfs2-lsplus explicitly

gives you the right value to use? This fixes a few lingering directory

handling bugs in the admin utilities.

This branch implemented patches to the 2.6.16 kernel for the proposed POSIX I/O extensions and those patches are under

the patches subdirectory.

It also implements the PVFS2 specific hooks for these system calls.

Tools that may be of immediate use to the pvfs2 general audience is the pvfs2-lsplus utility in src/apps/admin

that should be noticeably faster than the pvfs2-ls utility if there are a lot of objects in a single directory.

Other features are left out by configure and are not even built if the kernels do not support those features

and callbacks.

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...

* No error.h in freebsd

* linux allows Lu,Lx, and Ld to be interchangeable with llu,llx, and

lld. Other platforms (solaris, bsd) don't. Replaced all the L*

with ll*.

* bsd doesn't have mntent.h. use fstab.h and our own funcs.

* bsd doesn't know about ssize_t. Use size_t instead.

* bsd doesn't have asm errnos. Check for each of those

errno macros and if not defined define to -1

* check for db3/db.h db4/db.h header if db path is specified using

--with-db

* darwin has aio support builtin, doesn't need -lrt

* remove kernel stuff in pvfs2-types.h that sets WORDSIZE. gcc

defines __LP64__ on archs with 64bit longs so we use that instead.

* darwin's open doesn't accept O_LARGEFILE. off_t is an int64 by

default. define O_LARGEFILE if it hasn't been.

* need to run ranlib on darwin after libpvfs2.a gets installed to regenerate

table of contents

and admin utitilies), including the semantics of propigating the setgid bit

to new subdirectories or files. It also makes sure that setattr returns

an error if the user requests permission bits that are not supported

(just the setuid and sticky bits after this patch).

It turns out that there was already a getattr (or maybe a lookup?) in place

that we can get the information from [avoiding an additional getattr call].

- added command option -V (and --verbose) which can detect version

differences in the directory being read and will report them if this

switch is enabled

- make set-info test program update the mtime, rather than atime

- fixed bug on I/O that didn't do an opencache 'put' to release the

descriptor in use from the cache (pointed out by Avery)

- replace tabs in dbpf-keyval.c

- misc cleanups

GNU ls, but we can't unless we split this up into a two pass program that

retrieves all the data in the first pass and formats and displays it

afterward

character too early. for reference, gnu ls has 1 space between size and date:

this patch makes pvfs2-ls do that too.

PINT_* methods along with the others

- refactor blocking operations in terms of non-blocking operations

- change all sysint credential arguments to credential references

- memory leaks, bug fixes, cleanups

NOTE: this is a non-blocking first draft, updates are sure to come
