Main options here are `-y` and `-a`.
Passing both will allow the user to download the exact match image, use
it as-is, and set the config to use the rootfs by default.
Additional options `--distro-name` and `--distro-option` allows one to
select a particular distro version.
eg: `FEXRootFSFetcher -y -a --distro-name=ubuntu --distro-version=22.04`
* Will download the first Ubuntu 22.04 compressed in the json list
** Priority of erofs or squashfs depends on order in json and what the
host supports
Fixes a bug in `ExecAndWaitForResponse` where results > 1024 bytes would
overwrite data.
Switches from a custom format txt file to a json file.
JSON file now has a "Type" field to specify squashfs versus erofs.
JSON is now versioned so we don't need to move the file around, just
append to a new versioned segment.
Only shows erofs files if you have the bleeding edge `erofsfuse`
application.
This application was available starting with erofs-utils v1.5 which was
released on 2022-06-13, so it isn't available pretty much everywhere.
It can be useful to know in tooling when the current active FEXServer
has exited.
Two things can happen when this command is run.
No FEXServer is active, returns immediately.
A FEXServer is active, we query for a pidfd from the active server, then
we wait until it exits.
Both instances of this is valid to use.
This is a relatively invasive change since multiple things needed to
happen at once.
* Socket based logging is removed
* Logging has been replaced to only support stdout, stderr, and server
* Server is now default and replaces what FEXLogServer did
* Server logging now uses a pipe instead of a socket
* Can be faster than stderr and stdout since the application doesn't
need to wait on terminal output
* FEXMountDaemon has been removed
* Functionality has been merged in to FEXServer
* FEXServer is always executed on FEX initialization time
* Similar in behaviour to Wine's wineserver
* Can explicitly start this before using FEX for logging purposes
* Stays around until all instances of FEX exit
* Will stick around for a short amount of time in case of spurious
execution
* FEXServer will soon be extended to do more than logging and squashfs
mounting
* FEX rootfs scripts will need to be updated to support this path
* Just means rbinding the /tmp folder and forcing a FEXServer instance
to be alive
* Pressure-vessel works fine in this case since FEXServer will already
be running
* It already rbinds the host /tmp folder which is why this works
Gets rid of some magic numbers and reduces the number of things that
need to manually change (e.g. when supporting AVX and needing to
increase the xmm size).
The final tail of the file reading was incorrect, so our hashing was
"correct" but it was using stale data from the previous block size read.
Noticed this while wiring up the CI rootfs fetching since the hashing is
a lot simpler there.
Now instead of reading a tail, just attempt to read the full block size
and use the resulting data size instead. Confirmed it matches expected
results now.
In the process we are going to need to update hyperlinks and hashes
anyway, change the hash to XXH3 so it is faster to run.
Fixes a regression in fa87c73b9ee60a334eace2cdc3097725cbaf5b88; curl complains "curl: option -: is unknown" when trying to fetch a RootFS without this.
std::erase_if shouldn't allow you to modify the object passed in to the
predicate.
libstdc++ hasn't always enforced this but now it does with libstdc++12
By default we won't build with the interpeter to reduce user confusion.
The interpreter isn't really useful to end users so remove it.
Completely removes it from building except for the fallback operations.
This also removes the selection from FEXConfig to remove selection
confusion there.

Makes curl do its continue feature to give the users the best chance of
downloading a rootfs. We don't need to restart the full file transfer on
failure. Helps people with slower connections.
On failure to download, asks the user if they want to retry the download
rather than just exiting with a weird error about hash failure.
Once the image is downloaded, now changes options depending on if
squashfuse or unsquashfs works.
Prevents the user from selecting a bad option and getting unexpected
behaviour. Ideally we would do a squashfs mount test as well for
platforms that don't have working FUSE, like termux. This is harder to
get right and its for an unsupported platform, so I'm not going to
invest more time with it.
Fixes#1525Fixes#1526Fixes#1527
Location to check if curl, squashfuse, and unsquashfs are working.
unsquashfs is a bit more complex where it needs to parse the help output
to see if zstd is supported
In the case of launching without stdout/stderr then redirection could
have these constants be a redirected FD that sits in the same fd number.
Use -2 to indicate no redirection.
Use -1 to indicate closing traditional stderr/stdout
The rest will indicate if stdout and stderr should be replaced as
normal.
Making sure not to close the incoming fds if they matched the
stdout/stderr FD numbers.
Before doing anything that requires curl, actually check if it is
installed.
Then instruct the user to install curl before using.
Doesn't try installing curl itself since we don't have a clean way to
execute sudo from potentially GUI.
Fixes#1498
Adds a header only include utility folder that can be included from
everywhere.
Contains syscall helpers for older glibc and defines for older Linux
uapi headers missing some defines.
This tool supports both a zenity and tty interface.
TTY will be presented if available while Zenity will be used otherwise.
This tool pulls a rootfs list from https://rootfs.fex-emu.org/
It then allows you to select a rootfs from the list, download it, place
it in to the correct working folder, extract it if desired, and set it
as the current default RootFS.
This requires curl and potentially zenity installed to use.
Maybe also unsquashfs if the user chooses to extract the image.
This is an all in one tool to quickly get a new user up and running.
Additionally if you pass in a file path in to the tool, it will generate
an xxhash of the file and exit out. This is the hash used to ensure the
files are valid.
