The `glow` backend crashes on certain CPU-based graphics, particularly,
Windows running a CPU with integrated graphics using the basic
Microsoft Display Adapter driver.
`wgpu` seems to work everywhere.
Instead of saving P2Pool payout logs as they are, they are now
(de)serialized in the same [Display] format, e.g:
<DATE> <TIME> | <12_DOT_FLOAT> XMR | Block <BLOCK>
2022-09-31 12:53:52.8683 | 0.166122683521 XMR | Block 2,713,512
The parsing functions were updated to be able to read both raw
log lines and the new above format.
These couldn't be fit in before since there wasn't enough space.
They still can't all fit in, but the most important ones can be
after adjusting the font sizes and height spacing.
macOS moves "dangerous" applications into a read-only [/private]
filesystem. This messes up with the updater and default P2Pool and
XMRig paths.
If [/private] is detected, show a panic screen upon Gupax startup
telling the user to move it to [/Applications]. This _seems_ to
make macOS relax a little (after an arbitrary amount of time...)
There was a deadlock happening between the [Helper]'s [gui_api_p2pool]
and the GUI's [gui_api_p2pool], since the locking order was different.
The watchdog loop locking order was fixed as well. This was a pain to
track down, better than a data race... I guess.
Oh and keyboard shortcuts were added in this commit too.
Comment from code:
// The ordering of these locks is _very_ important. They MUST be in sync
// with how the main GUI thread locks stuff or a deadlock will occur
// given enough time. They will eventually both want to lock the [Arc<Mutex>]
// the other thread is already locking. Yes, I figured this out the hard way,
// hence the vast amount of debug!() messages.
//
// Example of different order (BAD!):
//
// GUI Main -> locks [p2pool] first
// Helper -> locks [gui_api_p2pool] first
// GUI Status Tab -> trys to lock [gui_api_p2pool] -> CAN'T
// Helper -> trys to lock [p2pool] -> CAN'T
//
// These two threads are now in a deadlock because both
// are trying to access locks the other one already has.
//
// The locking order here must be in the same chronological
// order as the main GUI thread (top to bottom).
Even with the parent-child relationship and direct process handle,
Gupax can't kill an XMRig spawned with [sudo] on macOS, even though
it can do it fine on Linux. So, on macOS, get the user's [sudo]
pass on the [Stop] button and summon a [sudo kill] on XMRig's PID.
This also complicates things since now we have to keep [SudoState]
somehow between a [Stop] and a [Start]. So there is macOS specific
code that now handles that.
