This removes all the hard-coded kernel base addresses from userspace
tools.
One downside for this is that e.g. Profiler no longer uses a different
color for kernel symbols when run as a non-root user.
|
|
|
|
This fixes displaying 64-bit addresses in readelf and also fixes
showing backtraces from core dumps on x86_64.

We have a dedicated format specifier which adds the "0x" prefix, so
let's use that instead of adding it manually.
|
|
Depending on the values it might be difficult to figure out whether a
value is decimal or hexadecimal. So let's make this more obvious. Also
this allows copying and pasting those numbers into GNOME calculator and
probably also other apps which auto-detect the base.
|
|
Also mark them as [[nodiscard]].

AK's version should see better inlining behaviors, than the LibM one.
We avoid mixed usage for now though.
Also clean up some stale math includes and improper floatingpoint usage.
|
|
If a test run has a lot of tests in it, and they fill up the terminal
buffer, it can be difficult to find out exactly which tests have failed
from your large test run. Make TestRunner print out an optional Vector
of failed test names at the end of the run, and have run-tests add each
failed or crashed test to a Vector it uses for this purpose.

This switches tracking CPU usage to more accurately measure time in
user and kernel land using either the TSC or another time source.
This will also come in handy when implementing a tickless kernel mode.
|
|
As threads come and go, we can't simply account for how many time
slices the threads at any given point may have been using. We need to
also account for threads that have since disappeared. This means we
also need to track how many time slices we have expired globally.
However, because this doesn't account for context switches outside of
the system timer tick values may still be under-reported. To solve this
we will need to track more accurate time information on each context
switch.
This also fixes top's cpu usage calculation which was still based on
the number of context switches.
Fixes #6473

This commit makes LibRegex (mostly) capable of operating on any of
the three main string views:
- StringView for raw strings
- Utf8View for utf-8 encoded strings
- Utf32View for raw unicode strings
As a result, regexps with unicode strings should be able to properly
handle utf-8 and not stop in the middle of a code point.
A future commit will update LibJS to use the correct type of string
depending on the flags.

This patch moves all the USB data from /proc/bus/usb to /sys/bus/usb.

This reverts commit 35394dbfaa23b44a293da85b20a63a10f73572c3.
I pushed the wrong button again, hopefully this will be the last of
such incidents.

* wasm: Don't try to print the function results if it traps
* LibWasm: Inline some very hot functions
These are mostly pretty small functions too, and they were about ~10%
of runtime.
* LibWasm+Everywhere: Make the instruction count limit configurable
...and enable it for LibWeb and test-wasm.
Note that `wasm` will not be limited by this.
* LibWasm: Remove a useless use of ScopeGuard
There are no multiple exit paths in that function, so we can just put
the ending logic right at the end of the function instead.

Previously, `new` was being recognised as an identifier, which was
preventing this from working.
|

No need for the key/value style here, just put it right after the type.
|
|
Add an implementation of 'comm' -- compare files line by line
|
|
We have a new config argument to add space separated exclude regex'
This is separate from "NotTestsPattern", because these are still Tests,
although they are not supposed to be run by the runner
This also adds the test for a working UserspaceEmulator to the tests run
|
|
Previously there was no way to modify existing user accounts.

List subdirectories encountered using -R or --recursive flags with ls.
|
|
|
|
Add a few extra tests as well, to make sure we don't have any future
TmpFs regressions.
|
|
This test exposed a kernel panic in is_user_range calculations, so let's
convert it to be a LibTest test so we can prevent regressions in mmap,
the page allocator, and the memory manager.
|

They should print the contents of capture group 1, if it exists.

Most people have only one screen.

The way overlay was drawn is not the correct way to achieve window
transparency in selection mode. With this change, shot window becomes
truely transparent.

Dr.POSIX requires expr to use BREs, so let's use BREs.
Fixes #8506.
