samba-technical on why this should stay as a simple null terminated
string (basically to make hand-written parsers easier)
(This used to be commit 0f1de4b1db7f0035e2b31f967d86de9306558968)
Support conformant [string] arrays
Eliminate utf8string
This breaks xattr binary compatibility with previous versions - is that a
problem?
(This used to be commit 7596c708ba6642473319a1b699a5a910a639e50d)
now able to use constructions like these:
[size_is(20)] int *x; -> Pointer to array of 20 ints
[size_is(20)] int x[]; -> Array of 20 ints
[size_is(20)] int *x[]; -> Array of 20 pointers to ints
[size_is(20,)] int *x[] -> Array of 20 pointers to ints
[size_is(,20)] int *x[]; -> Pointer to array of 20 ints
[size_is(,20)] int **x; -> Pointer to pointer to array of 20 ints
[size_is(20)] int x[][30]; -> 20 blocks of 30 ints
(This used to be commit ecf583da71c2f80be124c17fccdcb284b47e0695)
- Makes union handling less special
- Allows unions in arrays, etc
- Compatible with midl
- Pidl will warn about switch_type() and the type of the switch_is() variable being different
(This used to be commit dc6b4ffc82a191631bc16a4b93a4916a39183ec6)
array can now only be :
type *name[];
rather then :
type *name;
which was supported in the past. Warnings will be given when the first
syntax is used. Reasons for this change in behaviour include improved
readability and the fact that the second format makes dealing with multiple
levels of pointers harder.
(This used to be commit a416de5825c540fd3741731c4be05e9a659a6fdb)
is assumed to be "ptr" if not specified (just like midl).
The validator will warn when "ptr" is used at the moment, because
pidl only supports unique, ref and relative at the moment.
(This used to be commit 31bed62a9a6f7830f523d509b67970648d40aaef)
files don't need to match the type names in the generated headers
- with this type mapping we no longer need definitions for the
deprecated "int32", "uint8" etc form of types. We can now force
everyone to use the standard types int32_t, uint8_t etc.
- fixed all the code that used the deprecated types
- converted the IDL types "int64" and "uint64" to "dlong" and
"udlong". These are the 4 byte aligned 64 bit integers that
Microsoft internally define as two 32 bit integers in a
structure. After discussions with Ronnie Sahlberg we decided that
calling these "int64" was confusing, as it implied a true 8 byte
aligned type
- fixed all the cases where we incorrectly used things like
"NTTIME_hyper" in our C code. The generated API now uses a NTTIME for
those. The fact that it is hyper-aligned on the wire is not relevant
to the API, and should remain just a IDL property
(This used to be commit f86521677d7ff16bdc4815f9524e5286026f10f3)
- added support for sticky write times after a setfileinfo, by using a
write_time field in the DosAttrib xattr structure.
(This used to be commit 4a52fae82d8305e999f94f1947daa21dab54cdfd)
based on the current nttoken, which is completely wrong, but works as a start.
The ACL is stored in the xattr system.DosAcl, using a NDR encoded IDL
union with a version number to allow for future expansion.
pvfs does not yet check the ACL for file access. At the moment the ACL
is just query/set.
We also need to do some RPC work to allow the windows ACL editor to be
used. At the moment is queries the ACL fine, but displays an error
when it fails to map the SIDs via rpc.
(This used to be commit 3a1f20d874ab2d8b2a2f2485b7a705847abf1263)
The trickiest part about this was getting the sharing and locking
rules right, as alternate streams are separate locking spaces from the
main file for the purposes of byte range locking, and separate for
most share violation rules.
I suspect there are still problems with delete on close with alternate
data streams. I'll look at that next.
(This used to be commit b6452c4a2068cf7e837778559da002ae191b508a)
(the IDL, and the load/save meta-data logic)
- changed pvfs_resolve_name() to default to non-wildcard, needing
PVFS_RESOLVE_WILDCARD to enable wildcards. Most callers don't want
wildcards, so defaulting this way makes more sense.
- fixed deletion of EAs
(This used to be commit e7afd4403cc1b7e0928776929f8988aa6f15640b)
I decided to use IDL/NDR to encode the attribute, as it gives us a
simple way to describe and extend the saved attributes.
The xattr code needs to hook into quite a few more places in the pvfs
code, but this at least gets the basics done. I will start encoding
alternate data streams streams, DOS EAs etc soon using the same basic
mechanism.
I'll probably stick to "version 1" for the xattr.idl for quite a while
even though it will be changing, as I don't expect anyone to be
deploying this in production just yet. Once we have production users
we will need to keep compatibility by supporting all the old version
numbers in xattr.idl.
(This used to be commit c54253ed1b7dce1d14f43e747da61089aea87094)
