directory, where they were misplaced, and joined them to fcntl.cpp.
* Added openat().

returned by open() aren't suitable for directory iteration and because checks
have to be performed (like whether this is a directory at all and whether the
user has read permission).
* Added __create_dir_struct() for the attribute, index, and query open
functions to use instead.

beginning of the section, but probably relative to the beginning of the data
for the respective compilation unit (which might even make it useful again,
since it could be used as negative offset to the CIE). Relaxed the check even
more, so we always override the CIE offset when parsing .eh_frame sections.
This makes the variables appear in another test app Axel kindly provided.

Hopefully the last hurdle gcc 2 has prepared for preventing variables to show
up.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33924 a95241bf-73f2-0310-859d-f6bbb57e9c96
create a base type on the fly. This gets array types working with gcc 2
generated files.

.eh_frame section which seems to have almost identical contents (haven't found
any specification). So now we use .eh_frame with minor tweaks, when
.debug_frame is not available.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33914 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Since some types don't have names (e.g. pointer types or anonymous structs or
unions), each type does now also have a unique ID. The global type cache
registers types by ID and by name (if they have one). This fixes clashes of
types with empty names.
* Completely refactored the code dealing with variable values. Formerly we had
Variable and TypeComponentPath to navigate to a component, mapped to a
BVariant representing the value. Now we have:
* Interface Value with various subclasses (BoolValue, IntegerValue, etc.) to
represent a value, with the flexibility for more esoteric values.
* A tree of ValueNode+ValueNodeChild objects to represent the components of a
variable. On top of each ValueNodeChild sits a ValueNode representing the
value of the component, potentially having ValueNodeChild children. This
should allow casting a component value, simply by replacing its ValueNode.
* Interface ValueHandler and various implementations for the different value
types. It is basically a factory for classes allowing to format/display a
value.
* ValueHandlerRoster -- a registry for ValueHandlers, finding the best one
for a given value.
* Interface TypeHandler and various implementions for the different type
kinds (primitive, compound, address, etc.). It is basically a factory for
ValueNodes for that type.
* TypeHandlerRoster -- a registry for TypeHandlers, finding the best one
for a given type.
That's still a bit work in progress. It introduces at least one regression:
The VariablesView doesn't save/restore its state anymore. Will take a while
until that is added back.

If the view doesn't have a tool tip, pass the B_MOUSE_IDLE to the next handler,
so the parent view can show a tool tip. This makes tool tips in a column list
view possible (or at least reasonably easy).

one.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33901 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Made reference returned by _GetKey() const. That's sufficient.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33898 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Several fixes to get things building with gcc 4.
* Changed lookup of the _GLOBAL_OFFSET_TABLE_ symbol. It is hidden and static
and get_image_symbol() doesn't find it.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33897 a95241bf-73f2-0310-859d-f6bbb57e9c96
typedef, so it's clearer which one is the preferred one.
* Added BReference, a clone of BPrivate::Reference.
BPrivate::{Referenceable,Reference} are being phased out. Only the B* versions
should be used.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33879 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added implementation GraphicalUserInterface for the current GUI.
TeamDebugger does no longer know about TeamWindow.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33594 a95241bf-73f2-0310-859d-f6bbb57e9c96
both accordingly.
* The threads view shows the thread states now. Also added tool tips with
additional info.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33591 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Fixed misspelled MSG_*_BREAKPONT constants.
* model/Team: Added separate event class UserBreakpointEvent for user
breakpoints.
* SourceView::MarkerManager: Invalidate the markers when new source code is
set.
* Added breakpoints view.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33578 a95241bf-73f2-0310-859d-f6bbb57e9c96
indices we store in the fields of subsequent BRows. Fixes the broken threads
list in Debugger (should be some ticket -- can't access Trac ATM).

frame changes. Currently that's only the expanded/collapsed state of the
items in the tree view, but that already makes single stepping through code
much less annoying.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33512 a95241bf-73f2-0310-859d-f6bbb57e9c96
* IsNodeExpanded(): It always returned false due to a missing return.
* _SetNodeExpanded(): We must call our version of ExpandOrCollapse() or the
listeners won't be notified.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33508 a95241bf-73f2-0310-859d-f6bbb57e9c96
respective Type classes. StackFrameDebugInfo is pretty much out of work now,
but maybe something comes up later.
* Renamed GlobalTypeLookupContext to GlobalTypeCache and renamed its methods.
* A TeamDebugInfo does now have a GlobalTypeCache which is used for resolving
types. Formerly it was created per stack frame, so all types had to be
resolved after each single step. Single-stepping is usably fast again.
The disadvantage is that DWARF theoretically allows types properties to
depend on instruction/frame/frame base pointer and we don't support that
anymore. I can't think of a reasonable application for that feature, though.
* Refactored DwarfStackFrameDebugInfo:
- Moved the type classes into new DwarfTypes.{h,cpp}.
- Moved the creation of types into new class DwarfTypeFactory.
- Added class DwarfTypeContext which bundles all the dependencies of the type
classes.
* Made DwarfFile a BReferenceable.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33495 a95241bf-73f2-0310-859d-f6bbb57e9c96
always return the source string length, we can't really prevent an overflow
of the source address.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33489 a95241bf-73f2-0310-859d-f6bbb57e9c96
- Introduced GlobalTypeLookup interface and GlobalTypeLookupContext to look
up types by name and cache them.
- TeamDebugInfo implementes GlobalTypeLookup iterating through all
ImageDebugInfos, which in turn iterate through all SpecificImageDebugInfos.
- DwarfImageDebugInfo iterates through all compilation units, using
a temporary DwarfStackFrameDebugInfo to create the type.
- DwarfStackFrameDebugInfo no longer caches the types itself, but uses
GlobalTypeLookupContext. It uses GlobalTypeLookup to look up types not
defined in the compilation unit.
- DwarfFile: Made expression evaluation more robust, so that it also works,
when no subroutine entry, frame pointer, and instruction pointer are
available (and not used by the expression).
Basically works already, although the wrong compilation unit might be used
when resolving values for global types. It's also horribly slow, when there
are many types in the stack frame.
* DwarfStackFrameDebugInfo::ResolveArrayElementLocation(): The element location
piece size was set incorrectly (multiplied by 8, although bytes were
expected).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33477 a95241bf-73f2-0310-859d-f6bbb57e9c96
incorrectly. We must only replace the last component of the parent's path for
all following dimensions.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33476 a95241bf-73f2-0310-859d-f6bbb57e9c96
address overflows. Apparently at least the x86 string instructions generate
a general protection fault instead of a page fault, and we only use the fault
handler in the latter case (maybe we should change that, too). Fixes#4714.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33436 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Finished support for retrieving and displaying array element values.
* Added work-around for pointer types, if the base type isn't specified in the
debug info (as it should per specification).
* Added support for unspecified types, function types, and pointer to member
types. All types relevant for C++ should be supported now. There are still
quite a few TODOs, though.

monolithic vmware images as produced by the build system (by registering such
an image via the "diskimage" tool).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33388 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added new header headers/private/system/disk_device_types.h, which defines
the <DiskDeviceTypes.h> constants as macros and which can be used where the
constants cannot be used. The constants are defined using the macros, so now
there's only one place where the string literals should be specified.
* Use the macros in the partitioning systems. I was too lazy to also adjust the
file systems -- most of them seem to hard-code the string literal yet.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33386 a95241bf-73f2-0310-859d-f6bbb57e9c96
- Fixed vfs_get_vnode_from_fd() return type.
- Added vfs_open_vnode().
- Added a "bool traverseLeafLink" parameter to vfs_get_fs_node_from_path().
It was always resolving symlinks.
* device manager/devfs:
- devfs: get_node_for_path() no longer resolves leaf symlinks. That still
doesn't help with file disk devices, as creating partition wouldn't work
anyway.
- Pulled the module-related implementation part of BaseDevice into new class
AbstractModuleDevice and made all methods of BaseDevice virtual. Small
adjustments to devfs to be happy with the new BaseDevice interface.
- Added BaseDevice subclass FileDevice, which maps the interface to a file's
file descriptor. Still got a few TODOs, but should basically work.
- Use FileDevice for publishing file disk devices in devfs. Now those do
actually work, though there's some BFS trouble with one of the images I
tested.

as disk devices. It also demonstrates that the respective devfs functionality
is utterly broken.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33384 a95241bf-73f2-0310-859d-f6bbb57e9c96
- Changed the bit{Offset,Size} semantics. It's now more or less
aligned with the semantics of the respective DWARF DIE attributes.
DwarfStackFrameDebugInfo does now correctly translate the ValueLocations
returned by the DWARF layer (the bit piece location expression semantics is
different for some reason).
- ValueLocation is now aware of the target's endianess. The SetTo() method
needs that information to correctly meddle with the pieces.
- Support normalizing the pieces.
* Fixed retrieving the values of bit fields in various places. We still don't
handle the bit offset/size attributes of types correctly, but I haven't seen
those in actual debug info yet.
* Added support for enumerations. The variable view shows the enumerator names,
when available.
* Added partial support for subrange types. C++ doesn't have those -- we only
need them for array dimensions.
* Started adding support for array types. Still work in progress.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33314 a95241bf-73f2-0310-859d-f6bbb57e9c96

code.
* DwarfFile::EvaluateDynamicValue(): Added optional parameter to return the type
of the evaluated value, if available.
* Added source language info attribute to CompilationUnit.

correctly yet nor does type lookup beyond the current compilation unit.
* Made most of the debugger output configurable via a config header. By default
it's much less noisy now.

_ProcessJobs() loop waited for was processed by an inner one. Instead the loops
now check the state of the waiting job -- it will be changed from waiting as
soon as the job it waits for is done.

* Got rid of <dirent_private.h> -- the __DIR structure is private to dirent.c,
now. The attribute directory, index directory, and query functions use the
the public POSIX API, so does the kernel module code. Those components were
not initializing the structure correctly anymore since the introduction of
telldir()/seekdir().

a '\n', the other cutting off the last char.
* *getxattr() is supposed to return the attribute size when a 0 sized buffer
is supplied. Otherwise, if the buffer is too short, it needs to fail with
ERANGE.
* *listxattr(): The buffer pointer wasn't adjusted after each iteration.

So either +alphabranch or remove the declarations from <dirent.h>.

HDIO_GETGEO returned an incorrect size.

* Removed the headers/gnu from the default headers (the Jamfiles needing it
use it explicitly, now) and moved it under headers/compatibility/.
* Added libgnu.so to the image. Still untested, though.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32481 a95241bf-73f2-0310-859d-f6bbb57e9c96
(analoguously to libbsd.so).
* Added an implementation of the GNU/Linux xattr interface. xattrs are mapped
to Haiku attributes with type B_XATTR_TYPE. Haiku attributes are mapped to
xattrs by moving them into the "user.haiku." namespace and appending the
type to their name. Complete, but utterly untested yet.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32427 a95241bf-73f2-0310-859d-f6bbb57e9c96
that can be used for node attributes, when those originate from Linux xattrs.

* Always select POLLNVAL. We wouldn't get notified, if the FD was closed while
waiting.
* Skip negative FDs (as per POSIX standard).
* When encountering an invalid FD, we must not wait. Previously we did that as
long as any FD was valid.
* The return count must consider all FDs with non-null revents, including
invalid ones (revents is POLLNVAL then).
common_poll()/common_wait_for_objects():
* Don't bail out early, when no FDs/objects have been selected. We always want
to wait.
_user_poll()/_user_wait_for_objects():
* Copy the array back to userland even if common_*() returned an error. The
functions do now always fill in the resulting events.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32418 a95241bf-73f2-0310-859d-f6bbb57e9c96
* B_EVENT_INVALID is no longer passed to the FD's select()/deselect() hooks.
* Now we always attach the select info to the I/O context, even if no event has
been selected. The reasoning is that B_EVENT_INVALID is always automatically
selected and handled by the VFS, so we need the handle to notify on close().
