it's get_syscall() now.

* Print structures passed to ioctl() for several commands (networking and
terminal).
* Optional hex/decimal formatting of numbers (option -i).
* New level of detail option -d.

passing around stuff.

* Added rule AddSourceDirectoryToHaikuImage to copy source directories
onto the image. They will be placed in /boot/home/HaikuSource/...
according to their relative path. This should make it a bit more
comfortable to use gdb as a source level debugger. Alas, the
directories have to be made known to gdb individually (with the
"directory" command). I guess we should update to 6.6...

short, if the FD table size wasn't a multiple of 8.
* vfs_resize_fd_table() didn't seem to know at all about the
close-on-exit bitmap. The pointer in the io_context would point to
free()d memory afterwards. This explains the sporadically closed
stdin/out/err descriptors in programs started from Tracker and
Deskbar.

Basically reused the kernel implementation, but needed to hack it quite
a bit and also add an emulation of the required VM interface.
Completely untested yet.

possibility to initialize the AutoLocker without locking the object even
if it is unlocked yet. Especially in loops Lock()/Unlock() come handy
when an otherwise constantly hold lock needs to be unlocked for a short
time.
I suppose we should move the kernel utils AutoLocker implementation
to headers/private/shared, and drop the less powerful ObjectLocker.

mapped fully read-only (for both kernel and userland). Previously a
kernel read access to a yet unmapped r/w accessible userland address
would cause the page from the lower cache to be mapped with write
permission for userland (on x86 also for the kernel) thus e.g.
allowing a fork()ed child process to write to the parent process'
memory.
Fixes bugs #113 and #928.

write to the parent process' memory.
A fix follows...

{set,clear}_debugger_{break,watch}point(), allowing to set/clear break
and watchpoints for the calling team. When a break/watchpoint is hit,
the team enters the debugger. Handy in situations when the program in
question can't really be started in a debugger (or it would be
complicated to do so). The functions work only as long as no debugger is
installed for the team.
We clear the arch specific team and thread debug infos now, when a new
debugger is installed, thus clearing break- and watchpoints.

valid stderr. Thus one of the FDs for the pipes created for the initial
handshake with the fork()ed child process exec()ing the shell would have
number 2 and would be closed when the child process set up the
stdin/out/err environment for the shell, leading to the child and the
parent being killed by a SIGPIPE when they tried to access the pipes.
This change replaces the pipes mechanism by one using send/receive_data(),
which is probably even faster. I also reduced the handshake_t::msg field
to 128 bytes and replaced the sprintf()s writing to it by snprintf()s.
Fixes bug #627. Although they looked related, bugs #113 and #928 still
persist.

start address wasn't aligned and numBytes was a multiple of the page
size, the last page was ignored. A subsequent get_memory_map() would
return NULL as physical address for that page, if it hadn't been mapped
before (that function looks generally suspicious, IMHO). E.g. reads from a
device into an unaligned buffer that hadn't been touched before would
hit that problem. Fixes bug #1075. Might also fix other reported
problems (like #1056), since this bug could have cause all kinds of weird
behavior and crashes.

add-ons accordingly and removed the syscall.
* Removed send_notification().
* Reimplemented notify_listener(). It used the unimplemented
send_notification(). Now it has a chance to work. Note that
notify_listener() is obsolete. I would already have removed it, if
there weren't lots of FS implementations still using it (Hint!).

turn off the inclusion of src/Jamfile, and the rule DeferredSubInclude to
include a subdirectory in UserBuildConfig. Together they allow a developer
working on a subproject to reduce jam's parsing time when only building the

vnode::covered_by fields. Together with sMountOpLock it allows write
access, either lock alone suffices for read access. Before
sMountOpLock had to be acquired for read (and write) access, which
meant that while mounting/unmounting a FS path resolution would have
to wait. In case of the UserlandFS this would even cause a deadlock
while mounting if the client tried to resolve the path of the device
to be mounted (e.g. by opening it).
* Added a clarifying comment about read access to the
fs_mount::covers_vnode/root_vnode field and removed locking in
resolve_volume_root_to_mount_point() which was not necessary for
explained reasons.

* For B_EQUALS queries the first match would be skipped.
* Exact entry name matches were broken, since the used NameIndex::Find()
expected null-terminated keys with the \0 included in the key length
while it was fed only the raw string length.

name (saves copying the name, if that has to be done anyway) and added a
wrapper version with the old interface.
* dir_vnode_to_path() was broken for file systems that didn't support
the get_vnode_name() hook. It resolved the mount point too early, so
that it was searching the mount point and not the FS root dir for the
node. It uses the get_vnode_name() function now (before resolving the
mount point).

latter is just to be a good citizen.

change.
* The new notification functions are used instead of send_notification()
and notify_listener() now. Mapped them in the BeOS kernel emulation
accordingly. RamFS node monitoring seems to work now.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20298 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Made publish_vnode() available in userland. For old style FS add-ons
publish_vnode() is used when they request a new_vnode(). The semantics
of new_vnode() changed considerably in Haiku, but publish_vnode()
seems to do pretty much what the old new_vnode() did.
* The UserlandFS hosted RamFS begins to work under Haiku. It runs pretty
soon out of memory though (under vmware with 256 MB) and node
monitoring is broken ATM.

old interface is completely done in userland ATM.
It becomes more and more obvious that we probably need to provide
the kernel add-on with a bit more information about what the client FS
interface supports in the first place, so we can save unnecessary trips to
the userland. Opening/closing attributes for a FS using the old style
interface could be handled completely in the kernel add-on, for instance
(even if we lose a bit of accuracy wrt to open modes etc.).

need via library libuserlandfs_beos_kernel.so. Fine-tuned the legacy headers
so they can by used by the the kernel interface emulation code as well as by
the add-ons. This is actually a bit hacky, since we build everything in the
Haiku build environment and thus mix these old headers and Haiku's.

* Moved stuff need for the BeOS interface only into the beos_* namespace.
* Shuffled a few things around to reduce the block cache implementation
dependencies. compat.h and sysdep.c are gone accordingly.
* The whole UserlandFSServer builds now and could (at least theorectically)
drive a FS add-on implementing the old interface. The required emulation of
the BeOS kernel is not yet provided, though.

need to be adjusted.

UserFileSystem -> FileSystem
UserVolume -> Volume
KernelUserFileSystem -> BeOSKernelFileSystem

The BeOSKernel* classes are indeed intended to handle FS implementations
that use the (old) BeOS FS interface. We'll see how well that will work.

* Renamed a few parameters of the FS module hooks:
- *file in the attribute functions to *vnode
- v to vnode
- I could barely restrain myself from renaming the "_*" parameters. I
understand this marks return parameters, but I'd prefer a nicer prefix
or suffix (that doesn't makes you think this is a private/internal
identifier) like "out", "ret", "return", "result", or something similar.
I'd also like to propose renaming {read,write}_link() to
{read,write}_symlink(). Er, and do we need write_link() at all?

reference without being a referring entry.
* Reworked entry renaming. We do now remove the original entry first and
then create a target entry. Renaming directories didn't work before since
there would temporarily have been two links to a directory, which is not
allowed. Replacing an entry was also broken: The original entry was not
removed. Due to reversing the entry creation/deletion order we also do no
longer suffer from the Tracker bug, that entries would disappear from
queries when being renamed.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20204 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added missing locking in the query hooks.
* Added live query support similarly as done in BFS:
- Volume manages a doubly-linked list of live queries.
- Volume::UpdateLiveQueries() invoked from several places where it makes
sense (standard indices, Attribute::WriteAt(), and
BVolume::NodeAttributeRemoved()) notifies the live Query objects.
- Adjusted Query to be able to deal with hard links. Unfortunately Tracker
is a bit broken with respect to hard links, particularly in the query
windows. E.g. only one entry referring to a node is shown, and the renaming
method RamFS uses (link new entry, then unlink old one) causes renamed
entries to fall out of queries, even if they should still be in.
