refactor: Swap %Ld for %lld in all format usages

* %Ld is an undocumented alias for %lld in glibc.
* muslc doesn't implement it for this reason.
* While we will likely never drop %Ld support,
lets clean house and set a better example.

DiskProbe: Check we actually have a buffer before computing the offset.

Fixes #17709.

userland: Pass more sizes with ioctls where we can.

No "functional" change intended.

DiskProbe: style fixes...

DiskProbe: fix crash when trying to edit a package directory

/system and /home/config would crash diskprobe because DataEditor would
be left in an incompletely initialized state.

Also fix a memory leak: fAttribute was never freed, but is allocated with
strdup.

Fixes #10428.

DiskProbe: remove superfluous parentheses introduced in a31ac99

Diskprobe: some 64 bit fixes

* also warnings about comparisons between signed and non signed.

Revert r32402. Some problems are occuring in the attribute editor and I want to make sure they aren't caused by my patch before committing for good.

StringEditor : The TextView wasn't sending messages saying its content was modified by the user.
Symptoms :
* The Save menu item wasn't enabled
* the undo/redo menu item weren't neither

The fix I made was to commit the changes made by the user to the editor instance, by augmenting the InsertText and DeleteText from the TextView.
This fixes ticket #3507.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32402 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Removed src/kits/tracker/OpenHashTable.h. The shared version in
headers/private/shared is newer, though with small interface changes.
* Removed the unnecessary Debug.h include in
headers/private/shared/ObjectList.h.
* Adjusted sources using these headers, mostly by adding missing includes.
* Lots of automatic whitespace cleanup.

* DataEditor::SetTo() now checks if the reported block size is zero and then sets
it to the 512 byte default - this fixes bug #960.
* IconView::UpdateIcon() now uses 8-bit icon for get_device_icon(), as B_RGB32 cannot
work in this case.
* Also, in case it couldn't get an icon, it now tries to show the generic icon instead.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19940 a95241bf-73f2-0310-859d-f6bbb57e9c96

is now cleared - this changes the behaviour of bug #603, but doesn't fix
it (as this is no DiskProbe bug).
* Minor cleanup.

Fixes that make Haiku build with gcc 4. Mainly out of the following
categories:
* Missing includes (like <stdlib.h> and <string.h>).
* Linking against $(TARGET_LIBSTDC++) instead of libstdc++.r4.so.
* Local variables shadowing parameters.
* Default parameters in function definitions (as opposed to function
declarations).
* All C++ stuff (nothrow, map, set, vector, min, max,...) must be imported
explicitly from the std:: namespace now.
* "new (sometype)[...]" must read "new sometype[...]", even if sometype is
something like "const char *".
* __FUNCTION__ is no longer a string literal (but a string expression), i.e.
'printf(__FUNCTION__ ": ...\n")' is invalid code.
* A type cast results in a non-lvalue. E.g. "(char *)buffer += bytes"
is an invalid expression.
* "friend class SomeClass" only works when SomeClass is known before.
Otherwise the an inner class with that name is considered as friend.
gcc 4 is much pickier about scopes.
* gcc 4 is generally stricter with respect to type conversions in C.

Fixed two bugs:
- when undoing the first change, any later change would make that first change reappear
- in hex mode editing, changes were not merged because they changed the same byte
Updated version info.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@13801 a95241bf-73f2-0310-859d-f6bbb57e9c96

The DataEditor now has a separate entry_ref for attributes - that's used
to have access to the attributes of a root directory. Internally, only
this ref is used when accessing attribute data.
Also fixed an initialization bug in case the stream couldn't be properly
opened; some values were just set too late (could lead to strange things
as well as a crash).


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10481 a95241bf-73f2-0310-859d-f6bbb57e9c96

The DataEditor class now only redirects root directories to volumes; it
can now also open directories and symlinks, in which case nothing can be
done (but theoretically, the attributes could be changed).


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10472 a95241bf-73f2-0310-859d-f6bbb57e9c96

Always wrote fRealViewSize blocks; didn't use the correct calculated size...


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7624 a95241bf-73f2-0310-859d-f6bbb57e9c96

Read-only state was not properly initialized.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7055 a95241bf-73f2-0310-859d-f6bbb57e9c96

Now listens to file/attribute changes.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6825 a95241bf-73f2-0310-859d-f6bbb57e9c96

Implemented case insensitive search. It's now available in hex mode as well.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6822 a95241bf-73f2-0310-859d-f6bbb57e9c96

Implemented find functionality. The find panel is still missing though, it
just searches for "test".
The find itself is implemented in DataEditor::Find() which sets the editor
in read-only mode and searches for the specified data. It will update a
progress monitor, it will find data no matter if it's on a view size break,
and it is interruptible at any time.
The DataEditor change methods now respect the read-only mode, and return
B_NOT_ALLOWED in this case.
Renamed the UpdateLooper class to EditorLooper class, since it now also
runs the find action.
The ProbeView class now maintains the "Find Again" menu item; it's target
message always contains the item that last searched for.
The HeaderView will now show a "Stop" button while the search operation
is in progress; it also acts as the Find() progress monitor.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6789 a95241bf-73f2-0310-859d-f6bbb57e9c96

Now accepts directories, but redirects them to their volume instead; also
adopts the block size from the file system in that case.
Fixed the broken check for a device (would also succeed for other types,
stat.st_mode types cannot just be or'd).


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6783 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added the ability to merge changes. That means undo/redo now have a
handier granularity.
ReplaceChange will now try to merge with the next ReplaceChange if they
are adjacent.
Fixed compilation with tracing enabled.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6776 a95241bf-73f2-0310-859d-f6bbb57e9c96

Implemented changing the block size - that caused several changes to
DataEditor::SetViewSize()/SetViewOffset() because they did not correctly
update some values under certain circumstances.
There is now a kMsgDataEditorParameterChange instead of just ...OffsetChange;
the message will contain information about what has changed exactly.
Added a new kDataViewPreferredSize notifier that indicates a change of
the preferred size of the DataView. The ProbeView now listens to that
instead of knowing when to update the window limits.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6772 a95241bf-73f2-0310-859d-f6bbb57e9c96

ApplyChanges() didn't always work correctly. Save() could crash with a
wrong index to the fChanges list.
Added the compile time possibility to trace the data editor changes.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6765 a95241bf-73f2-0310-859d-f6bbb57e9c96

version of the file from any state.

all changed states during the lifetime of the object upon destruction.
Added some comments.
Uncommented the IsModified() method (does not yet work correctly, though).


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6760 a95241bf-73f2-0310-859d-f6bbb57e9c96

DataEditor::InitCheck() is now properly working for all types.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6747 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added some argument bound checks in Replace() and SetViewOffset().
Replace(), Insert(), and Remove() now locks the editor themselves.
ReplaceChange::Normalize() corrected the size for the right reason in a wrong way.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6741 a95241bf-73f2-0310-859d-f6bbb57e9c96

Accidently added only an int32 for the size, not an int64.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6738 a95241bf-73f2-0310-859d-f6bbb57e9c96

Now maintains the undo/redo state watcher, and also the data update
containing the range of affected bytes.
Added missing initialization of fLastChange and fFirstChange.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6733 a95241bf-73f2-0310-859d-f6bbb57e9c96

No longer takes an attribute for a file, or a device for an attribute.
Implemented attribute support.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6709 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added a UpdateIfNeeded() method that you can call when you are not
interested in the data at all.
No longer imitates the BHandler observer model, but directly send
its update messages to the observers.
Now also stores the entry_ref of the file/device in the editor.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6704 a95241bf-73f2-0310-859d-f6bbb57e9c96

Too bad the DataEditor did not report the correct size for devices... :)


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6624 a95241bf-73f2-0310-859d-f6bbb57e9c96

The DataEditor class is now subclasses from BLocker instead of aggregating
it. This way, it can directly be used in the BAutolock class, and also provides
some more sophisticated locking functions.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6621 a95241bf-73f2-0310-859d-f6bbb57e9c96

Now can also retrieve the size of a disk device.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6619 a95241bf-73f2-0310-859d-f6bbb57e9c96

Extended watching mechanism (it now works more like the BHandler watching
mechanism) - it's not really used yet, though.
Fixed some variable initialization bugs and missing return values.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6566 a95241bf-73f2-0310-859d-f6bbb57e9c96

Implemented the document handling foundation for DiskProbe.
Does not yet maintain the window position on disk (nor any other settings).


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6549 a95241bf-73f2-0310-859d-f6bbb57e9c96

Removed now unused arguments from the ReplaceChange constructor.
The last change also makes sure that changes can be applied at any time,
no matter if the block is currently loaded or not.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6104 a95241bf-73f2-0310-859d-f6bbb57e9c96

The DataChange constructor must no longer make any changes to the buffer.
DataChange::Apply() will now remember the string instead, so that undo/redo
will work correctly even if the underlying data has changed in the mean time.
DataEditor::AddChange() will now apply the change as well.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6103 a95241bf-73f2-0310-859d-f6bbb57e9c96

Implemented DataEditor::Redo(), and RemoveRedos(); the latter will now be
called by AddChange().
Fixed ApplyChanges() to only apply changes up to (and incl.) the last change;
it won't apply all changes anymore.
DataEditor::Undo() and Redo() now lock themselves.
Added some more simple tests to DiskProbe.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6102 a95241bf-73f2-0310-859d-f6bbb57e9c96

Started to work on a DiskProbe replacement as a side project.
Implemented the basic editor engine that has features like undo/redo
and everything else DiskProbe could possibly need - not complete yet,
though it already has everything that would be needed for a 1:1 DiskProbe
duplicate.
The DiskProbe app is currently just a small text based test for that engine.

Added a UpdateIfNeeded() method that you can call when you are not
interested in the data at all.
No longer imitates the BHandler observer model, but directly send
its update messages to the observers.
Now also stores the entry_ref of the file/device in the editor.

Too bad the DataEditor did not report the correct size for devices... :)

The DataEditor class is now subclasses from BLocker instead of aggregating
it. This way, it can directly be used in the BAutolock class, and also provides
some more sophisticated locking functions.

Now can also retrieve the size of a disk device.

Extended watching mechanism (it now works more like the BHandler watching
mechanism) - it's not really used yet, though.
Fixed some variable initialization bugs and missing return values.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6566 a95241bf-73f2-0310-859d-f6bbb57e9c96

Implemented the document handling foundation for DiskProbe.
Does not yet maintain the window position on disk (nor any other settings).


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6549 a95241bf-73f2-0310-859d-f6bbb57e9c96

Removed now unused arguments from the ReplaceChange constructor.
The last change also makes sure that changes can be applied at any time,
no matter if the block is currently loaded or not.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6104 a95241bf-73f2-0310-859d-f6bbb57e9c96

The DataChange constructor must no longer make any changes to the buffer.
DataChange::Apply() will now remember the string instead, so that undo/redo
will work correctly even if the underlying data has changed in the mean time.
DataEditor::AddChange() will now apply the change as well.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6103 a95241bf-73f2-0310-859d-f6bbb57e9c96

Implemented DataEditor::Redo(), and RemoveRedos(); the latter will now be
called by AddChange().
Fixed ApplyChanges() to only apply changes up to (and incl.) the last change;
it won't apply all changes anymore.
DataEditor::Undo() and Redo() now lock themselves.
Added some more simple tests to DiskProbe.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6102 a95241bf-73f2-0310-859d-f6bbb57e9c96

Started to work on a DiskProbe replacement as a side project.
Implemented the basic editor engine that has features like undo/redo
and everything else DiskProbe could possibly need - not complete yet,
though it already has everything that would be needed for a 1:1 DiskProbe
duplicate.
The DiskProbe app is currently just a small text based test for that engine.
