Extra features of FileSwitch, introduced in version 1.70
========================================================
i) Path variables work properly. Whenever <thing>: prefixes a path the
relevant path variable will be used (<thing>$Path). Paths in path variables
will be resolved in the same way. The following new errors may occur:
* Path variable had multiple entries and was used for a write operation
* One of the path variables used refers to itself
ii) FileSwitch manages directories. From now on FileSwitch will process a
path, resolving out wildcards, absolute directory references (%, @, \ and &)
and sorting out parent references (^). There should be minimal impact on how
things work, except for the following:
* All filing systems will get all absolute directories working the same.
* It may be possible to delete current and library directories.
* Paths which go through non-existant directories, but end up at an
existing object will work (eg a.b.c.d.^.^.^.f will end at a.f even
if b, c or d don't exist).
iii) FileSwitch provides support for MultiFS-like filing systems. The
support provided by FileSwitch means that 'seamless' access to MS-DOS hard
disc partition files, or MS-DOS discs, can be implemented. In effect, the
foreign disc format is not noticed by the user when it is accessed from the
desktop. As a consequence of this the object type has been extended:
Object type Meaning
0 Not present
1 File
2 Directory
3 File and Directory - this means this file has been
identified as a MultiFS file, and hence can be treated as a
directory too. Objects of this type may be treated as both
files and directories.
An alternative way to think of the object type is as a bit field:
Bit Meaning when set
0 Object may have file-like operations done to it
1 Object may have directory-like operations done to it
iv) Given a filename, FileSwitch can be asked to process it to produce a
mostly canonical form (mostly in the sense that the case may be different,
and wildcards may not be sorted out if the wildcarded object doesn't
exist!). So
* 'a' may be resolved to 'adfs::HardDisc4.$.current.a' if the current
directory is 'adfs::HardDisc4.$.current'.
* 'a*' may be resolved to the same thing if 'a' exists and is the first
match for 'a*', but, if there is no match for 'a*', then
'adfs::HardDisc4.$.current.a*' will be returned.
* 'A' may be resolved to 'adfs::HardDisc4.$.current.A', which should be
considered the same as 'adfs::HardDisc4.$.current.a'.
OS_FSControl 37 (FSControl_CanonicalisePath)
On entry
r0 = 37
r1 = Pointer to path to be canonicalised
r2 = Pointer to buffer to be filled in
r3 = Pointer to system variable name of path to use, or 0 if none
r4 = Pointer to default path to use if no system variable is specified
or if that variable doesn't exist, or 0 if no path is the default
r5 = Buffer length
On exit
Buffer filled in with 0-terminated canonicalised name, and
r5 = number of spare bytes in the buffer after and including
the 0 terminator. If the buffer would have overflowed,
then this will be taken to negative the overflow, but
the overflow won't actually have happened. This
provides a machanism for finding out how much buffer
is needed.
This may be used as a two-pass process:
Pass 1:
In:
r0 = 37
r1 = Pointer to path
r2 = 0
r5 = 0
Out:
r5 = -(length of canonicalised path)
Pass 2:
Claim buffer of the right size (1-r5, not just -r5 as a space for the terminator is needed)
In:
r0 = 37
r1 = Pointer to path
r2 = Pointer to claimed buffer
r5 = size of claimed buffer
Out:
r5 should be 0, but check to make sure!
v) Given a file handle, fileswitch will return the name of the file.
OS_Args 7 (OSArgs_ReadPath)
On entry
r0 = 7
r1 = file handle
r2 = Pointer to buffer to be filled in
r5 = Buffer length
On exit
Buffer filled in with 0-terminated canonicalised name, and
r5 = number of spare bytes in the buffer after the 0 terminator.
If the buffer would have overflowed, then this will be
taken to negative the overflow, but the overflow won't
actually have happened. This provides a machanism for
finding out how much buffer is needed.
This call can be used in the same way as OS_FSControl 37.
vi) FileSwitch now processes the conversion of file info into filetype
information.
OS_FSControl 38 (FSControl_InfoToFileType)
On entry
r0 = 38
r1 = a pointer to the object's name
r2 = object's load address
r3 = object's execute address
r4 = object's length
r5 = objects's attributes
r6 = object's type (file/directory)
On exit
r2 = object's type:
Special values:
-1 untyped
&1000 directory
&2000 application directory (directory whose name starts with a '!').
OS_File 20-23 (OSFile_ReadWithType, _ReadWithTypePath, _ReadWithTypePathVar
and _ReadWithTypeNoPath)
On Entry
r0 = 20, 21, 22 or 23
r1 = Pointer to name of object
On exit
r0 = object's type
r1 unchanged
r2 = Object's load address or top word of date stamp
r3 = Object's execute address or bottom word of date stamp
r4 = Object's length
r5 = object's attributes
r6 = Object's type:
Special values:
-1 untyped (r2, r3 are load and execute address)
&1000 directory
&2000 application directory (directory whose name starts with a '!').
OS_GBPB 12 (OSGBPB_ReadDirEntriesFileType)
On entry
r0 = 12
r1 = pointer to directory name
r2 = start address of data in memory (word aligned)
r3 = number of names to read from directory
r4 = offset of first item to read from directory (0 for start)
r5 = buffer length
r6 = Pointer to (Wildcarded) name to match
On exit
r0-r2 unchanged
r3 = number of objects read
r4 = offset of next item to read
r5, r6 unchanged
This call is similar in function to OS_GBPB 10, except the buffer is filled
in with entries like this:
Offset Contents
0 Load address or high word of date stamp
4 Execute address of low word of date stamp
8 Length
12 File attributes
16 Object type
20 Object's file type (as for OS_File 20-23)
24 Object's name (null terminated)
This diff is collapsed.
Mike,
A new UpCall_Modifying file reason code:
R0 = 3 (UpCall_ModifyingFile)
R1 = external handle
R2 = size to ensure
R8 = filing system information word
R9 = 512 (upfsfile_EnsureSize)
Called when a file's size is ensured.
--Jonathan
PRM Bugs
FSEntry_Func 11 (page 992)
r6 = 0 (cannot specify a context) is wrong. A context can be specified.
OS_FSControl 1 (page 886)
The default library is typically & (this being the default for FileCore
based filing systems), not $.Library as stated in the PRM.
OS_FSControl 11 (page 897)
r2 0 : old filing system to be selected
should read
r2 > 0 : filing system number specified
The following should be noted about OS_FSControl 11:
r1 in Regs out
blah.blah vlsgf r1=r1 in
r2 = -1
r3 = 0
<FS>:blah r1 past :
r2 = number of <FS>
r3 = 0
<FS>#fred:blah r1 past :
r2 = number of <FS>
r3 past #
<path>:blah r1 = r1 in
r2 = -1
r3 = 0
<path>#fred:blah r1 = r1 in
r2 = -1
r3 past #
#fred:blah r1 = r1 in
r2 = -1

New service calls specific to or used by FileSwitch:
Service_DiscDismounted
This is used by FileSwitch to Unset directories on eht dismounted disc. For
details of this new service call see FileCore.doc.Services
Service_CloseFile (&68)
Purpose:
To request that any module with a file open which is, or is a child of the
named object, that can also be closed without causing too much hassle should
close it. This would be issued to cause, for example, a DOSFS partition file
to be closed by FileSwitch. This doesn't cause problems as the partition
would be spontaneously reopened when needed later.
To issue this service call:
SWI OS_ServiceCall
Entry
r1 = &68 (Service_CloseFile)
r2 = object needing to be closed
r3 = 0
Exit
r1,r2 preserved
r3 = number of files closed as a result of this service call.
The value in r2 should be a pointer to a nul-terminated string which is a
canonical path of the object to be closed.
To respond to this service call:
Entry
r1 = &68 (Service_CloseFile)
r2 = object needing to be closed
r3 = number of files closed so far this service call
Exit
r1,r2 preserved
r3 incremented by the number of files you closed.
The spec of r2 is as above. This service call should not be claimed. If you,
the receiver of this service call, has any file open which is, or is a child
of the named object which you can close without much bother, then this
should be done. Increment r3 by the number of files you closed before
passing this service on.
I would suggest supporting RISC OS 3.10 properly as it saves you lots of
faff. Although more entry points may be needed, the effort to provide full
functionality (directory setting, processing of ^.s in paths and the such)
is much reduced as it is handled mostly by FileSwitch. I would recommend the
following settings (assuming a network flavour filing system).
Filing system information word:
Bit Setting Meaning
31 ? If set you suport special fields - probably want this clear
30 0 Streams aren't interactive (information bit only)
29 0 Null length file names are not allowed
28 0 Don't allow an open call if the file doesn't exist
27 0 Don't tell the filing system about flush calls (may want 1 instead)
26 0 FSEntry_File 9 (read info, no length) not provided
25 0 FSEntry_Func 20 (*FileInfo) not provided
24 0 FSEntry_Func 18 (set contexts) not provided
23 1 MultiFS extensions supported
22 0 Paths always given to filing system from $. onwards
21 0 FileSwitch stores directory settings (*Dir, *Lib etc) for this filing system
20 1 FileSwitch does *Load with Open, GBPB, close
19 1 FileSwitch does *Save with Open, GBPB, close
18 0 FileSwitch should process *Access strings itself
17 0 No extra info word
16 0 Filing system isn't read only
15-8 ? Limit on number of open files - 0 for no limit
7-0 ? Your filing system's number
The following Filing system entry points will be used:
FSEntry_Open
0 read
2 update
Return when a file is opened with the file information word set to:
Bit Setting Meaning
31 ? Write permitted to file - return as appropriate
30 ? As above, for Read
29 0 Object isn't a directory
28 0 Buffered GBPB only
27 0 Stream isn't interractive
And quote a buffer size which is a power of 2 (256 bytes?) and the
length of the file. If you can get the allocate space too then
return that, otherwise round up the file's size to the next multiple
of the buffer size and return that.
These settings mean the following interfaces will be used:
FSEntry_GetBytes
FSEntry_PutBytes
These will be the multiple byte varieties. You will be asked to read
beyond the file's end - simply read to the file's end and don't
return an error. This happens as FileSwitch thinks it's driving a
disc-based filing system and reads the half-filled block at a
file's end just before modifying it and writing the whole block
back.
FSEntry_Args
3 Write file extent (size) (just before the file is closed
after modification)
6 Notify of flush (happens just before close after modification)
7 Ensure file size - return without error if no appropriate
action.
8 Write zeroes
9 Read file datestamp
10 ImageStampIs. Return without error as this is only
appropriate to removable disc based filing systems (FileCore)
FSEntry_File
1 Write catalogue information
5 Read catalogue information
6 Delete object
7 Create file
8 Create directory
*10 ReadBlockSize - error this if you want
FSEntry_Func
(7 Set filing system options replaced by _Func 28)
8 Rename
*10 Boot filing system - do nothing if booting inappropriate
(11 Read name and boot option of disc replaced by _Func 23 and 27)
14 Read directory entries
15 Read directory entries and information
16 Shutdown
*17 Print start up banner - depends on entry in FS info block being -1
*19 Read diretory entries and information - can error this one
23 CanonicaliseSpecialAndDisc
*24 Resolve wildcard - return with r4=-1 to get FileSwitch to do this
*25 ReadDefectList - error this if you want
*26 AddDefect - error this if you want
27 ReadBootOption - don't error this, return 0 instead
28 WriteBootOption - error this, or do nothing, it's up to you
*29 UsedSpaceMap - error this
30 ReadFreeSpace - this might be useful to support
*31 NameDisc - inappropriate for network - error it?
32 StampImage - don't error this, do an appropriate action, or do nothing
*33 ObjectAtOffset - error this
Those entries in () are for information only - they won't be called. Those
entries with a * can have trivial implementations.
All paths will be fully canonicalised by FileSwitch before the filing system
gets them, that is where appropriate will include special field (optional
as determined by CanonicaliseSpecialAndDisc and FS infor word bit), disc
name (as determined by CanonicaliseSpecialAndDisc), and path from $. The
filing system need not handle any of:
Directory setting - *Dir, *Lib etc
Parsing paths relative to set directories (@.thing.blah or %.doofa)
Performing catalogue listings of any sort (*Cat, *Ex etc)
Parsing *Access strings
^.s in paths
As these are handled by FileSwitch.
I believe writing such a filing system is less work than the RISC OS 2.00
way where the large gaps in calls used are needed to be supported.

International stuff:
1. 8 bit characters in names on *ALL* filing systems !!!
2. Text direction for names.
3. New interfaces for above.
4. Time and date in * commands (info ex fileinfo)
5. Territory_TextToString
6. Uppercasing for UpperCase macro
JC's unusual app$path corrupting linked strings? Maybe caused by memory shortage.
Add namedisc interface
Add 'access level' interface (public/private)
file left open after *load to memory

5098 more update failure - can't see new files created outside desktop
5142 MultiFS files don't get upcalled properly
The Truncate Feature.
This feature is a scheme whereby filing systems which cannot handle long
filenames for one reason or another can be controlled as to what they do
about it. Under normal circumstances they used to give a 'Bad name' error if
a long filename was passed to them. Under the new scheme this property can
be changed so that when they are given a long filename they truncate it
before using it.
This is controlled by the *configure Truncate command. Two possible
parameters are allowed: Configure Truncate on and Configure Truncate off.
This controls the CMOS byte &1c, bit 0. Bit 0 being 0 means off and 1 means
on. When the Truncate bit is on then filenames will be truncated instead of
errors being generated.
As a filing system this bit should be read (and other bits in that byte
masked off) when the filing system is initialised.
Clarifications of openning a file in the new FileSwitch:
open_nodir on File+Directories should open the object without an error. So,
I suppose the bit has to mean 'Give me an error if this object, when opened
has no data that can be read from it using GBPBs and related calls'.
