8b1108e485 Everywhere: Pass AK::StringView by value 2021-11-11 01:27:46 +01:00

5ce753b74d Kernel: Make Inode::traverse_as_directory() callback return ErrorOr
This allows us to propagate errors from inside the callback with TRY().

88b6428c25 AK: Make Vector::try_* functions return ErrorOr<void>
Instead of signalling allocation failure with a bool return value
(false), we now use ErrorOr<void> and return ENOMEM as appropriate.
This allows us to use TRY() and MUST() with Vector. :^)

79fa9765ca Kernel: Replace KResult and KResultOr<T> with Error and ErrorOr<T>
We now use AK::Error and AK::ErrorOr<T> in both kernel and userspace!
This was a slightly tedious refactoring that took a long time, so it's
not unlikely that some bugs crept in.

Nevertheless, it does pass basic functionality testing, and it's just
real nice to finally see the same pattern in all contexts. :^)

6f69d5204f Kernel: Make Inode::flush_metadata() return a KResult
Even if this goes nowhere yet, we have to start building an error
propagation path somewhere.

899cee8185 Kernel: Make KBuffer::try_create_with_size() return KResultOr
This allows us to use TRY() in a lot of new places.

4a9c18afb9 Kernel: Rename FileDescription => OpenFileDescription
Dr. POSIX really calls these "open file description", not just
"file description", so let's call them exactly that. :^)

b481132418 Kernel: Make UserOrKernelBuffer return KResult from read/write/memset
This allows us to simplify a whole bunch of call sites with TRY(). :^)

566c5d1e99 AK+Kernel: Move KResult.h to Kernel/API for userspace access
This commit moves the KResult and KResultOr objects to Kernel/API to
signify that they may now be freely used by userspace code at points
where a syscall-related error result is to be expected. It also exposes
KResult and KResultOr to the global namespace to make it nicer to use
for userspace code.

ae197deb6b Kernel: Strongly typed user & group ID's
Prior to this change, both uid_t and gid_t were typedef'ed to `u32`.
This made it easy to use them interchangeably. Let's not allow that.

This patch adds UserID and GroupID using the AK::DistinctNumeric
mechanism we've already been employing for pid_t/ProcessID.

5416fa252a Kernel: Add tightly typed ISO9660Inode::fs() overload
We know the fs() is always an ISO9660FS, so let's be nice and make fs()
return that when called on an ISO9660Inode. :^)

d30d776ca4 Kernel: Make FileSystem::initialize() return KResult
This forced me to also come up with error codes for a bunch of
situations where we'd previously just panic the kernel.

ef2720bcad Kernel: Make Inode::lookup() return a KResultOr<NonnullRefPtr<Inode>>
This allows file systems to return arbitrary error codes instead of just
an Inode or not an Inode.

0d468f2282 Kernel: Implement a ISO 9660 filesystem reader :^)
This commit implements the ISO 9660 filesystem as specified in ECMA 119.
Currently, it only supports the base specification and Joliet or Rock
Ridge support is not present. The filesystem will normalize all
filenames to be lowercase (same as Linux).

The filesystem can be mounted directly from a file. Loop devices are
currently not supported by SerenityOS.

Special thanks to Lubrsi for testing on real hardware and providing
profiling help.
