2022-10-25Utilities: Use new global variables at /sys/kernel/ directoryLiav A
2022-07-12Everywhere: Add sv suffix to strings relying on StringView(char const*)sin-ack
Each of these strings would previously rely on StringView's char const* constructor overload, which would call __builtin_strlen on the string. Since we now have operator ""sv, we can replace these with much simpler versions. This opens the door to being able to remove StringView(char const*). No functional changes.
2022-01-28Revert "Userland: Invoke tzset in apps that care about time zones"Timothy Flynn
This reverts most of commit ede5c9548e55d8216dba21ed431b9e53d085a248. The one change not reverted is ClockWidget.h, so that the taskbar clock can continue to notice time zone changes.
2022-01-25Userland: Invoke tzset in applications that care about time zonesTimothy Flynn
In most applications, we invoke tzset once at startup for now. Most of these are short lived and don't need to know about time zone changes. The exception is the ClockWidget in the taskbar. Here, we invoke tzset each time we update the system time. This way, any time zone changes can take effect immediately.
2022-01-23Userland: Add promises to programs that will read /etc/timezoneTimothy Flynn
This will require unveiling /etc/timezone itself for reading, as well as the rpath pledge promise.
2021-11-28Everywhere: Use default execpromises argument for Core::System::pledgeBrian Gianforcaro
2021-11-23LibCore+LibSystem: Move syscall wrappers from LibSystem to LibCoreAndreas Kling
With this change, System::foo() becomes Core::System::foo(). Since LibCore builds on other systems than SerenityOS, we now have to make sure that wrappers work with just a standard C library underneath.
2021-11-22w: Port to LibMain :^)Andreas Kling
This unlocked a bunch of TRY() opportunities. Not just system calls, but also Core::File::open() and JsonValue::from_string().
2021-11-17AK: Make JSON parser return ErrorOr<JsonValue> (instead of Optional)Andreas Kling
Also add slightly richer parse errors now that we can include a string literal with returned errors. This will allow us to use TRY() when working with JSON data.

2021-07-18Everywhere: Improve CPU usage calculationTom
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
2021-06-01Userland: Replace most printf-style APIs with AK::Format APIs :^)Linus Groh
2021-05-31Userland: Remove a bunch of unused includesLinus Groh
As reported by CLion.
2021-05-23LibCore: Make ProcessStatisticsReader return results in a VectorAndreas Kling
The HashMap API was overkill and made using this less ergonomic than it should be.
2021-05-12LibCore+Everywhere: Move OpenMode out of IODeviceAli Mohammad Pur
...and make it an enum class so people don't omit "OpenMode".
2021-05-07Utilities: Convert StringBuilder::appendf() => AK::FormatAndreas Kling

2021-04-22Everything: Move to SPDX license identifiers in all files.Brian Gianforcaro
SPDX License Identifiers are a more compact / standardized way of representing file license information. See: https://spdx.dev/resources/use/#identifiers This was done with the `ambr` search and replace tool. ambr --no-parent-ignore --key-from-file --rep-from-file key.txt rep.txt *
