e2fsck considers all blocks reachable through any of the pointers in
m_raw_inode.i_block as part of this inode regardless of the value in
m_raw_inode.i_size. When it finds more blocks than the amount that
is indicated by i_size or i_blocks it offers to repair the filesystem
by changing those values. That will actually cause further corruption.
So we must zero all pointers to blocks that are now unused.
Previously the directions omitted that you have to specify
`-CMAKE_CXX_COMPILER` when building the Fuzzers. This
would cause all kinds of weird problems at compilation and
link time. You can't specify one or the other, they must
both be pointing at clang in order for things to work as
experted. Fix this by updating the documentation to specify
that the user should specify both the C and CXX compiler explicitly
to be safe, as well as forcing the cmake clang argument handling
to modify the CXX compiler variable instead of the C version.
This links the dynamic linker against libgcc.a instead of having
our own copy of the math functions.
For now we need to specify -fbuilding-libgcc as a hack to work
around a bug with the -nodefaultlibs flag. Once everyone is on
the latest toolchain version this can be removed.
This fixes the -nodefaultlibs flag for gcc which previously
linked against libgcc_s anyway. Even though this is a toolchain
patch we don't need to rebuild the toolchain right away.
There is no need to iterate through all events in a profile when
loading the timeline view, as soon as we see one event we can
move on to the next process.
The current method of emitting performance events requires a bit of
boiler plate at every invocation, as well as having to ignore the
return code which isn't used outside of the perf event syscall. This
change attempts to clean that up by exposing high level API's that
can be used around the code base.
This unix classic attempts to classify and identify information about
given files based on various heuristics. In this case, we're relying on
the Core::MimeData detector for file type and LibGfx::ImageDecoder for
additional metadata if the given file is an image.
It's very simple for now, but adding new detectors should be quite easy.
This attempts to guess the mime-type from a given set of bytes from the
start of a file. It only supports a few well-defined patterns for now,
but it's a start!
This patch removes an incorrect way for TextDocument::text_in_range
to return early when the first line of the selection was empty. This
fixes an issue in TextEditor where the status bar showed that 0
characters are selected when the selection started on an empty line.
The architecture here is a little bit convoluted. I ended up making a
new container widget (TimelineContainer) that works similarly to
GUI::ScrollableContainerWidget but has two subwidgets (a fixed header
that only scrolls vertically, and the timeline view that scrolls on
both axes.)
It would be nice to generalize this mechanism eventually and move it
back into LibGUI, but for now let's go with a special widget for
Profiler so we can continue iterating on the GUI. :^)
Instead of smashing together all the samples into a single timeline,
make one per process and put them all in a ScrollableContainerWidget.
This makes it much easier to see which processes were active and when.
No timeline is displayed for processes with zero samples in the profile.
Legally we could just return a null pointer, however returning a
pointer other than the null pointer is more compatible with
improperly written software that assumes that a null pointer means
allocation failure.
With the goal of centralizing all tests in the system, this is a
first step to establish a Tests sub-tree. It will contain all of
the unit tests and test harnesses for the various components in the
system.
Ext2 directory contents are stored in a linked list of ext2_dir_entry
structs. There is no sentinel value to determine where the list ends.
Instead the list fills the entirety of the allocated space for the
inode.
Previously the inode was not correctly resized when it became smaller.
This resulted in stale data being interpreted as part of the linked list
of directory entries.
This is used for `sys.platform`, so it's important to get it right and
ideally never change it again. When not cross-compiling this would
append the `uname -r` version number, so let's explicitly override the
generated value and set it to `serenityos`. Various other systems do
this as well.
This makes the following work:
>>> import webbrowser
>>> webbrowser.open("http://serenityos.org")
As well as this well-known easter egg:
>>> import antigravity
Pretty cool! :^)
