Timothy 62af82f494 AK: Use east const in MappedFile 2021-08-07 12:48:22 +02:00
Timothy bc75ca4fe5 AK: Add method to create MappedFile from fd 2021-08-07 12:48:22 +02:00
Andreas Kling 58b5a8f3c0 AK: Update mmap name for MappedFiles on SerenityOS
Looking at process memory maps is a lot nicer when you can see the paths
of MappedFile mappings.

Andreas Kling b91c49364d AK: Rename adopt() to adopt_ref()
This makes it more symmetrical with adopt_own() (which is used to
create a NonnullOwnPtr from the result of a naked new.)

Brian Gianforcaro 1682f0b760 Everything: Move to SPDX license identifiers in all files.
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.

Andreas Kling ef1e5db1d0 Everywhere: Remove klog(), dbg() and purge all LogStream usage :^)
Good-bye LogStream. Long live AK::Format!

Andreas Kling 5d180d1f99 Everywhere: Rename ASSERT => VERIFY
(...and ASSERT_NOT_REACHED => VERIFY_NOT_REACHED)

Since all of these checks are done in release builds as well,
let's rename them to VERIFY to prevent confusion, as everyone is
used to assertions being compiled out in release.

We can introduce a new ASSERT macro that is specifically for debug
checks, but I'm doing this wholesale conversion first since we've
accumulated thousands of these already, and it's not immediately
obvious which ones are suitable for ASSERT.

Ben Wiederhake c9bb887c55 Everywhere: Remove unnecessary headers 1/4
Arbitrarily split up to make git bisect easier.

These unnecessary #include's were found by combining an automated tool (which
determined likely candidates) and some brain power (which decided whether
the #include is also semantically superfluous).

My favorite #include:

    #include "Applications/Piano/Music.h" // You can't have too much music in life!

Andreas Kling 1a08ac72ad LibC+Everywhere: Remove open_with_path_length() in favor of open()
This API was a mostly gratuitous deviation from POSIX that gave up some
portability in exchange for avoiding the occasional strlen().

I don't think that was actually achieving anything valuable, so let's
just chill out and have the same open() API as everyone else. :^)

Andreas Kling 2f3b901f7f AK: Make MappedFile heap-allocated and ref-counted
Let's adapt this class a bit better to how it's actually being used.

Instead of having valid/invalid states and storing an error in case
it's invalid, a MappedFile is now always valid, and the factory
function that creates it will return an OSError if mapping fails.

AnotherTest 6131417904 AK: Make MappedFile store why it is invalid
This makes AK::MappedFile save the errno either open() or mmap() failed
with.

Andreas Kling 94ca55cefd Meta: Add license header to source files
As suggested by Joshua, this commit adds the 2-clause BSD license as a
comment block to the top of every source file.

For the first pass, I've just added myself for simplicity. I encourage
everyone to add themselves as copyright holders of any file they've
added or modified in some significant way. If I've added myself in
error somewhere, feel free to replace it with the appropriate copyright
holder instead.

Going forward, all new source files should include a license header.

Andreas Kling 73fdbba59c AK: Rename <AK/AKString.h> to <AK/String.h>
This was a workaround to be able to build on case-insensitive file
systems where it might get confused about <string.h> vs <String.h>.

Let's just not support building that way, so String.h can have an
objectively nicer name. :^)

Sergey Bugaev 55d7810fab AK: Do not keep an open FD in MmappedFile
We only need an open FD while establishing the mapping,
and can close it immediately after mmap() call.

Andreas Kling c110cf193d Kernel: Have the open() syscall take an explicit path length parameter.
Instead of computing the path length inside the syscall handler, let the
caller do that work. This allows us to implement to new variants of open()
and creat(), called open_with_path_length() and creat_with_path_length().
These are suitable for use with e.g StringView.

Andreas Kling c79b048198 MappedFile: Fix misuse of StringView::characters().
This makes me wonder if the open() syscall should take characters+length
and we'd compute the length at the LibC layer instead. That way we could
also provide an optional non-POSIX open() that takes the length directly..

Robin Burchell 0dc9af5f7e Add clang-format file
Also run it across the whole tree to get everything using the One True Style.
We don't yet run this in an automated fashion as it's a little slow, but
there is a snippet to do so in makeall.sh.
