...when sending the whole view state over the link.
Also inherit the fill rule when pushing states (DrawState
copy constructor). A somewhat sloppy oversight, I must add.
* I don't know what I am doing here, but the test app_server only
ever built for me recently when I disabled the define, so I might
as well commit this...
After load_image() the child thread is suspended and the parent is
expected to resume it later. However, it is possible that the parent
attempts to resume its child after it has been notified that the image
had been loaded but before the child managed to suspend itself. In such
case the child would suspends itself after that wake up attempt and,
consequently will not be ever resumed.
To mitigate that problem flag Thread::going_to_suspend has been added
which helps synchronizing thread suspension and continuation in a similar
way that "traditional" thread blocking is performed. This means that
the child should behave in a following manner: set its going_to_suspend flag,
notify the parent (i.e. any thread that may want to resume it), acquire
its scheduler_lock and suspend itself if the going_to_suspend flag is set.
The parent should follow pattern: clear going_to_suspend flag of the thread
that is about to be resumed, acquire that thread scheduler_lock and enqueue
it in a run queue if it is suspended.
Thanks Oliver for reporting the bug and identifying what causes it.
Most of the actual UserEvent work is done in DPC so that we don't have
to care about the limitations of the context in which UserEvent::Fire()
is invoked. This requires appropriate management of lifetime of UserEvent
instances to make sure that DoDPC() method is always called on a valid
object.
This fixes building openssh on the bootstrap image.
The real problem is that it picks up this file instead of the histedit.h
from libedit, though. But since this include was missing anyway, it
makes sense to fix this file, too.
* BView gets SetFillRule/FillRule methods. The fill rule is part of the
view state.
* The B_NONZERO rule is the default. This is what we implemented before.
* The B_EVEN_ODD rule is the other common possibility for this, and
we need to support it to help WebKit to render properly.
* Add isb just because.
* pdziepak pointed out that ARMv5 and before
had different barrier support.
* pdziepak also mentioned that dsb was too strong
for __sync_synchronize
* On ARMv6 or older, we do a simulated dsb.
* Move __sync_synchronize into thread.c in libroot
and use the new arch_atomic.h dsb/dmb defines.
* Gets arm @bootstrap-raw to end of bootstrap.
* Don't assume verdex as it isn't clear this was
occurring.
* Make an educated guess on HAIKU_BOOT_PLATFORM
based on provided board (but still allow it to
be overridden)
* Error out if user doesn't populate
HAIKU_BOOT_PLATFORM or enters an unknown board
name.
* You need to add "-sHAIKU_BOOT_BOARD=xxx" to
your jam to build for the proper ARM device.
* Rename beagle to beagleboneblk as per the
documentation.
* BSecureSocket::CertificateVerificationFailed() took a BCertificate
instance by value as parameter.
BCertificate deletes internal data in its destructor. Passing an
object by value creates a copy, so the copy attempted to delete
the internal data again during its destruction.
This caused mail_daemon to crash here when it came across a failed
certificate.
* Fix: pass BCertificate object as reference.
* Was causing LLVM to fail to build on x86_64
* Make XINT64 adjust based on architecture like
config/types.h to ensure these macros match
uint64 and int64 at all times.
* Resolves#10566
* Use atomic_get_and_set for return value
* Atomics are no longer volatile
* Add missing arch_cpu_pause stub
* Move arch_cpu_idle to arch_cpu header to match
other architectures
* This will be used to implement compressed http streams
* Remove the custom BDataOutput class, and use BDataIO instead, for
easier integration with existing code.
inline const floats are a gcc extension. It is possible to do it in a
standard way in C++11 using constexpr, but then gcc will reject the
previously accepted nonstandard syntax.
* ... instead of queuing it for the job thread. The advantage is that
the request will be handled immediately and clients won't have to wait
for transactions (which may even require user feedback) to finish. It
complicates Volume a bit, since there are now two threads that may
access it. The shared data have been moved to a State object which is
protected by a lock.
* For commit transaction requests check whether another package request
is already pending/in progress before queuing a job. Fail immediately,
if there is.
Fixes bug #10039.
Everything untested, but compiles, so it must work. The idea is to introduce
BAffineTransform additionally to the existing Origin and Scale properties of
BViews. One may use it in parallel or as an alternative. Painter in app_server
is not yet aware of the additional transformation. It is however already used
to transform drawing coordinates. It probably needs to work differently,
perhaps only in Painter and AGGTextRenderer.
* This is less pretty, but we need access to the connector
to find the HPD gpio pin mask on the card.
* dp_aux communications seem to work again.
* If you have a DisplayPort item attached to your card you
may want to just unplug it at this point. We attempt DP
link training and it fails. This failure will also cause
other monitors to not function as app_server still isn't
multi-head aware (#10486)
This is required on OS X and other systems which do not have the glibc
extensions for regular expressions (FreeBSD is not one of them as it
already includes gnuregex in /usr). With this there are no hardcoded
non-standard paths for OS X anymore.
regex.c and regex.h are from the official gnuregex 0.12 distribution,
the only modification is that I added __BEGIN_DECLS and __END_DECLS to
regex.h.
Make Cmd+Left and Cmd+Right work the same as Option+Left and
Option+Right, that is, they do word-wise navigation.
Make Option+Up go to beginning of paragraph and Option+Down go to end
of paragraph like Cmd+Left and Cmd+Right used to.
Unfortunately option shortcuts are currently eaten by S&T until #9431
gets fixed.
* Command+Left goes to beginning of line, ignoring softwrap
* Command+Right goes to the end of line, ignoring softwrap
* Home goes to beginning of line, accounting for softwrap
* End goes to end of line, accounting for softwrap
* Option+Left goes to previous word
* Option+Right goes to next word
* Command+Home and Command+Up go to beginning of document
* Command+End and Command+Down go to end of document
Shift with any of the above also selects the text.
This is similar to how the text editor Eddie works.
For non-US keyboards, the extra 102th/105th key is used to reach \. But,
we also need it to report | when shifted (this is the key left to
"enter").
This affects only USB keyboards. Thanks to gordoncjp for reporting!
Add SetSupportedTypes() and SetIcon[ForType]() versions with an
additional bool updateMimeDB parameter. If false, the method doesn't
update the MIME DB entries for the type.
When switching AppMetaMimeCreator from BMimeType to Database the
SetIcon[ForType]() calls with a BBitmap* ended up calling the vector
icon version with the icon_size as the data size argument, thus not only
not writing the bitmap icon attributes, but also clobbering the vector
icon attribute.
* BSolver/LibsolvSolver: Add FullSync() method. It uses libsolv's
SOLVER_DISTUPGRADE mode.
* BPackageManager: Add FullSync() using the new solver mode.
* pkgman: Add full-sync command.
The new command is similar to the update command without arguments, just
more aggressive, allowing downgrading or even removal of packages, to
match the state of the repositories. Just like "update" it doesn't work
properly yet.
UserEvent can be fired from scheduler_reschedule() i.e. while holding current
thread scheduler_lock. If the current thread goes sleep and during reschedule
one of its timers sends a signel to it, then scheduler_enqueue_in_run_queue()
attempts to acquire again its scheduler_lock resulting in a deadlock.
There was also a minor issue with both scheduler_reschedule() and
scheduler_enqueue_in_run_queue() acquiring current CPU scheduler mode lock.
Some websites set cookies expiring in the (not so) far future, after year 2038.
So, using time_t to store the cookie expiration date won't do. Use the
BDateTime class instead.
This makes goodsearch.com login work again (#10460).
Adjust Database{Location} to only attempt to create a mimetype when
actually necessary, and fail otherwise if a writable version doesn't yet
exist. Correspondingly, adjust callers such as
DatabaseLocation::DeleteAttribute(). Fixes a problem where a caller asking
to perform a mimeset could fail early due to SetSupportedTypes() attempting
to update the read-only mime database entry supplied by a package, and
consequently most of the mimeset operations would be skipped.
* Fix incorrect cpu vendor name mapping
* Add additional CPU architectures
* Add additional CPU vendors
* Rework PowerPC arch_system_info passing
PVR back for cpu model
* Set max cpu to 1 for PPC until atomic functions are finished
* We have atomic functions inline in the kernel and assembly
code in libroot post-scheduler merge... isn't that a lot of
duplication?
Add boot loader debug menu option "Save syslog from previous session
during boot". If enabled (defaults to true), the previous session's
debug syslog data is copy to a separate buffer and passed to the
kernel, which writes it back to the file /var/log/previous_syslog.
As long as Haiku still boots, this should now be the most convenient way
to retrieve the output from a kernel crash.
https://github.com/druga/haiku-stuff/tree/master/intel_extreme
Rebased against current sources.
* The BIOS video mode sometimes reports a scaled mode instead of the
physical panel dimensions. Get the data from the VBT table as well, and
use it if the reported resolution is bigger.
* On first boot, force the panel native mode so the user doesn't have to
set it manually.
* Only allow a single head at a time on i855gm, as the card can't drive
both heads at the same time.
* Detect when a new requested mode is the same as the current one, and
skip modesetting in that case. Avoids screen flickering when changing
workspaces.
* Fix some cases of misdetecting which pipes to enable
* Instead of creating an OpenSSL context ofor each socket, use a global
one and initialize it lazily when the first SecureSocket is created
* Load the certificates from our certificate list so SSL certificates
sent by servers can be validated.
* Add a callback for signalling that certificate validation failed, the
default implementation proceeds with the connection anyway (to keep the
old behavior).
* Introduce BCertificate class, that provides some information about a
certificate. Currently it's only used by the callback mentionned above,
but it will be possible to get the leaf certificate for the connection
after it's established.
Review of the API and implementation is welcome, before I start making
use of this in HttpRequest and WebKit to allow the user to accept new
certificates.
Use standard error codes instead.
This allows using error code returned by the underlying functions
directly, and makes it possible to use strerror for debugging. So, we
can also remove StatusString() from the various *Request classes.
Previous implementation based on the actual load of each core and share
each thread has in that load turned up to be very problematic when
balancing load on very heavily loaded systems (i.e. more threads
consuming all available CPU time than there is logical CPUs).
The new approach is to estimate how much load would a thread produce
if it had all CPU time only for itself. Summing such load estimations
of each thread assigned to a given core we get a rank that contains
much more information than just simple actual core load.
* Previously PE binaries would trigger the "incorrectly
executable" dialog. Now we get a special message for
B_LEGACY_EXECUTABLE and B_UNKNOWN_EXECUTABLE
* Legacy at the moment is a R3 x86 PE binary. This could
be extended to gcc2 binaries someday far, far, down the
road though
* The check for legacy is based on a PE flag I see
set on every R3 binary (that isn't set on dos ones)
* Unknown is something we know *is* an executable, but
can't do anything with (such as an MSDOS or Windows
application)
* No performance drops as we do the PE scan last
* Tested on x86 and x86_gcc2
This field forces kernel to track each CPU load all the time. It is not
a problem with the current scheduler on a multicore systems, but on
single core machnies or with any other future scheduler this field may
become just an unnecessary burden. It isn't difficult for an application
to compute CPU load by itself when it needs it.
When calling Stop(), we expect the request thread to exit as soon as
possible. Closing the connection unlocks it from any blocking read() or
write(), avoiding some lockup situations.
* My BeagleBone gcc defines __ARMEL__ but not
__ARM__ which breaks the native tool builds
* As ARM was originally Little Endian, we assume
__ARM__ means as such.
* Look for Big Endian ARM and define the needed big
endian preprocessors
* Add behavior constant B_POP_UP_BEHAVIOR which adds a pop-up marker
to the button (similar to that of BMenuField).
* Add methods [Set]PopUpMessage(). To set/get the the message that is
sent to the button's target when the pop-up marker is clicked.
* Add methods SetFlat()/IsFlat(). A flat button doesn't draw its frame,
unless the mouse is hovering over it or it is otherwise activated.
* As a side effect this change also activates the hover glow that was
already implemented in BControlLook, but not activated in BButton.
* Draw(): Remove the non-BControlLook code.
* GetPreferredSize(): Implement based on _ValidatePreferredSize() to
avoid code duplication.
* Draw(): Fix off-by-one error. The label was too close to the box.
* Draw(), _ValidatePreferredSize(): Add icon support.
_ValidatePreferredSize() is now actually aligned with what Draw()
expects. The preferred width is now a tight fit; there were three or
four pixels of empty space before.
Due to the fixed check box position the layout isn't that nice in
some situations (particularly with an icon larger than the text),
IMHO.
The icon is meant as an addition to or replacement of the label. Icon
bitmaps for various states of the control (off, on, partially on, each
enabled or disabled, plus up to 125 custom states) can be set
individually via SetIconBitmap() (getter IconBitmap()).
The convenience method SetIcon() can be used to set the bitmaps for the
standard states from a single bitmap; it also supports cropping the
icon to its non-transparent area. Code borrowed from BIconButton.
* Update the previously unused frame_type and background_type enums.
* Add methods GetFrameInsets(), GetBackgroundInsets(), GetInsets() to
get the insets for a given frame type, background type, or both
respectively.
The baudrate constant for MIDI speed was after all the others in BeOS,
and we have to keep them with the same values for things to work.
Moreover, the constants in SerialPort.h were not changed, so everything
was out of sync and all apps using BSerialPort ended up using the wrong
speed.
Add a comment in termios.h to make sure this doesn't happen again.
* Add possible control state B_CONTROL_PARTIALLY_ON and support it in
BCheckBox and BControlLook.
* BCheckBox: Add partialStateToOff property defining whether the
partial state should transition to off. Defaults to false (i.e.
partial to on).
* This is primarily a service method for ports of widget tool kits
that require single-threaded GUI. DispatchExternalMessage() calls
DispatchMessage(), but also sets fLastMessage, so that
[Detach]CurrentMessage() work correctly. This allows to detach a
message in DispatchMessage() when called from the window thread,
add it to a global queue, and later process the queued messages in
a different thread that calls DispatchExternalMessage().
* BLooper/BWindow: Make sure fLastMessage is accessed only when locked.
atomic_{get, set}64() are problematic on architectures without 64 bit
compare and swap.
Also, using sequential lock instead of atomic access ensures that
any reads from cpu_ent::active_time won't require any writes to shared
memory.
The client code is not supposed to change the topology info.
It would be also nice if cpu_topology_node::children was an array of
pointers to const but that would require several const_casts in the
topology tree generation code so it's probably not worth it.
Apparently, reading from dr3 is slower than reading from memory
with cache hit.
Also, depending on hypervisor configuration, accessing dr3 may cause
a VM exit (and, at least on kvm, it does), what makes it much slower
than a memory access even when there is a cache miss.
* BUrlResult is back, with ContentType and Length methods.
* BHttpResult subclasses it and use HTTP header fields to implement
those
* Introduce BDataRequest for "data" URIs. These embed the data inside
the URI, either as plaintext or base64 encoded.
Add get_safemode_option_early() and get_safemode_boolean_early() to get
safemode options before the kernel heap has been initialized. They use a
simplified parser.
* VMTranslationMap:
- Add DebugPrintMappingInfo(): Given a virtual address it is supposed
to print the paging structure information for that address. To be
implemented by derived classes.
- Add DebugGetReverseMappingInfo(): Given a physical addresss it is
supposed to find all virtual addresses mapped to it. To be
implemented by derived classes.
* X86VMTranslationMapPAE: Implement the new methods
DebugPrintMappingInfo() and DebugGetReverseMappingInfo().
* Add KDL command "mapping". It supports both virtual address lookups
and reverse lookups.
__flatten_process_args() does now have the executable path as an
additional (optional) parameter. If specified, the function will read
the file's SYS:ENV attribute (if set) and use its value to modified the
environment it is preparing for the new process. Currently supported
attribute values are strings consisting of "<var>=<value>" substrings
separated by "\0" (backslash zero), with '\' being used as an escape
character. The environment will be altered to contain the specified
"<var>=<value>" elements, replacing a preexisting <var> element (if
any).
A possible use case would be setting a SYS:ENV attribute with value
"DISABLE_ASLR=1" on an executable that needs ASLR disabled.
* VMAddressSpace: Add randomizingEnabled property.
* VMUserAddressSpace: Randomize addresses only when randomizingEnabled
property is set.
* create_team_arg(): Check, if the team's environment contains
"DISABLE_ASLR=1". Set the team's address space property
randomizingEnabled accordingly in load_image_internal() and
exec_team().
We can send the data directly to the output socket instead of copying it
into a BString first, at the cost of very slightly less information in
debug output.
* Create new interface for cpuidle modules (similar to the cpufreq
interface)
* Generic cpuidle module is no longer needed
* Fix and update Intel C-State module
* Increase FIFO buffer capacity from 32 to 64 KiB and the FIFO atomic
write size ({BUF_SIZE}) from 512 bytes to 4 KiB (both like Linux).
* Fix *pathconf(..., _PC_PIPE_BUF). It was returning 4 KiB although the
implemented atomic write size was 512 bytes only. Now both *pathconf()
and the FIFO implementation refer to the same constant.
When using the copy constructor of BNetEndpoint the socket of the
original endpoint gets dup'ed. The Accept() method later directly reset
the fSocket member of the newly created BNetEndpoint to the socket
returned by accept(). The socket dup'ed by the copy constructor was
therefore leaked.
Of course dup'ing the socket and copying the local and remote addresses
is superfluous in the accept case, as these members all get set to new
values. To reduce that overhead there is now a new private constructor
that directly gets the final socket and remote and local address.
A DatabaseLocation is passed to the constructor and used to verify that
the sniffed MIME type is installed instead of BMimeType::IsInstalled().
This makes the add-on independent of the default MIME DB.
Add a constructor and a SetTo() method with a
BPackageResolvableExpression parameter instead of a path. The path of
the package satisfying the expression is used.
The new functionality lives in libpackage as it uses the package kit.
Most of the hooks don't strictly need a non-empty implementation. The
defaults now simply throw exceptions in those that do. This allows the
class to be instantiated, which is useful when a BPackageManager is only
used for finding packages.
Require the installation interface and the user interaction handle to
be passed to the constructor. Formerly, derived classes set them
manually in their constructors. This makes using the class without
having to subclass it possible.
It's a browser for the system package content, where entries can be
selected to blacklist them. The selected entries are removed from the
packagefs instance in the boot loader, so that e.g. selected drivers
won't be picked up. The paths are also added to the safe mode driver
settings and will be interpreted when the system packagefs instance is
mounted by the kernel.
* Make Menu and MenuItem polymorphic.
* MenuItem:
- Make SetMarked() virtual, so it can be overridden.
- Add SetSubmenu() and Supermenu().
- Delete the submenu in the destructor.
* Menu:
- Add Entered()/Exited() hooks. They frame the time the user navigates
the menu or any of its submenus. The hooks allow for subclasses
populating their item list dynamically.
- Add SortItems().
* Update boot loader menu copyright text to include 2013, now that it is
over soon. :-)
In each installation location, it is now possible to create a settings
file "packages" that allows to blacklist entries contained in packages.
The format is:
Package <package name> {
EntryBlacklist {
<entry path>
...
}
}
...
<package name> is the base name (no version) of the respective package
(e.g. "haiku"), <entry path> is an installation location relative path
(e.g. "add-ons/Translators/FooTranslator").
Blacklisted entries will be ignored by packagefs, i.e. they won't appear
in the file system. This addresses the issue that it may be necessary to
remove a problematic file (e.g. driver, add-on, or library), which would
otherwise require editing the containing package file.
The settings file is not not "live". Changes take effect only after
reboot (respectively when remounting the concerned packagefs volume).
* get_architectures() returns the primary and the secondary
architectures in one array. That turned out to be convenient.
* Add C++ versions for get[_secondary]_architectures(), returning a
BStringList.
* Add get_architecture(), get_primary_architecture(),
get_secondary_architectures(), guess_architecture_for_path() to get
the caller's architecture, the primary architecture, all secondary
architectures, or the architecture associated with a specified path
respectively.
* Rename the find_path*() functions to find_path*_etc() and add an
optional architecture parameter. Add simplified find_path*()
functions.
* BPathFinder: Add FindPath[s]() versions with an architecture
parameter.
Implement BNetworkRoster::GetRoutes() and BNetworkInterface::GetRoutes().
Also implement BNetworkInterface::GetDefaultGateway().
There is code duplication at the moment, and the api only supports IPV4.
By passing the window pointer to ScreenSaverRunner contructor and using that
to lock the window when drawing instead of getting the window from the
Window() method of the view. This is safer.
* Remove useless dummy protocol loop in UrlRequest
* Stop HTTP requests before deleting the socket and other things the
loop may still be using
* Deletion of items from the authentication map wasn't working
* Remove some debug traces
Start the screensaver in the window thread instead of the runner
thread so that there is no lock contention for the window lock in
the runner thread when the saver starts.
The view that gets drawn into is assumed to have been prepared before
being passed to the runner thread, and this assumption has been made
true for the screensaver preview and screen_blanker apps.
Eliminate fHasStarted and the corresponding HasStarted() method in
ScreenSaverRunner as they are no longer needed.
Drawing still happens in the runner thread, and still needs to lock
the window thread potentially causing contention, yet, there
is a timeout here so the contention won't freeze the screensaver window,
only delay drawing the screensaver.
Drawing could be moved to the window thread via message passing to avoid
lock contention with the window but this would defeat a big part of the
purpose of having a separate rendering thread.
This fixes#10125 and #4260
* pin idle threads to their specific CPUs
* allow scheduler to implement SMP_MSG_RESCHEDULE handler
* scheduler_set_thread_priority() reworked
* at reschedule: enqueue old thread after dequeueing the new one
* virtio_scsi can have 16384 luns, though we cap at 256 as our scsi_ccb
only uses uchar as a type for target_lun and target_id members.
* minor code cleanup in scsi_scan_bus().
* Thread::scheduler_lock protects thread state, priority, etc.
* sThreadCreationLock protects thread creation and removal and list of
threads in team.
* Team::signal_lock and Team::time_lock protect list of threads in team
as well.
* Scheduler uses its own internal locking.
* The UNMAP command is theoretically much faster, as it can get many block
ranges instead of just a single range.
* Furthermore, the ATA TRIM command resembles it much better.
* Therefore, fs_trim_data now gets an array of ranges, and we use SCSI UNMAP
to trim.
* Updated BFS code to collect array ranges to fully support the new
fs_trim_data possibilities.
No functional change intended.
Renamed title => name in regular constructors,
No right or wrong here but consistant now.
Renamed data => archive in Achive constructor,
Ditto.
* No need for the atomically changed variables to be declared as
volatile.
* Drop support for atomically getting and setting unaligned data.
* Introduce atomic_get_and_set[64]() which works the same as
atomic_set[64]() used to. atomic_set[64]() does not return the
previous value anymore.
The new functions are meant to replace many uses of find_directory():
* find_paths() is supposed to be used when the directories of a certain
kind in all installation directories are needed (e.g. font
directories, add-on directory, etc.). Using this API makes code
robust wrt addition or removal of installation locations.
* find_path() is supposed to be used when files/directories associated
with a loaded program, library, or add-on need to be found (e.g. data
files or global settings).
* find_path_for_path() is similar to find_path(), but it starts from a
given path instead of an image.
The flag main purpose is to avoid race conditions between event handler
and cancel_timer(). However, cancel_timer() is safe even without
using gSchedulerLock.
If the event is scheduled to happen on other CPU than the CPU that
invokes cancel_timer() then cancel_timer() either disables the event
before its handler starts executing or waits until the event handler
is done.
If the event is scheduled on the same CPU that calls cancel_timer()
then, since cancel_timer() disables interrupts, the event is either
executed before cancel_timer() or when the timer interrupt handler
starts running the event is already disabled.
This causes configure of gcc/binutils to fail its test for sys/time.h, which
in turn causes compilation of gcc/binutils to fail.
Found trying to do a @bootstrap-raw build for ARM.
The authentication state is stored (in a hash map, using the domain+path
as a key) in the UrlContext class. It can then be reused for multiple
requests to the same place. We also lookup stored authentications for
parent directories and stop at the first we find.
Authentication state is not stored on disk (unlike cookies), and there
can only be one for each domain+path.
