> moreover it means that we'd want two different behaviors when receiving SIGINT (whether it's a genuine unix signal or one sent by the server if we follow the tests result above) perhaps, the solution would be in the default_ctrl_handler to only terminate the program if attached to a console, or in the program group of a unix console
One way or another, terminating GUI process in response to Unix SIGINT is a Wine thing, it's not something we can express in Windows terms. If kernelbase part is not suitable, maybe we may just terminate process from ntdll when we're not connected to console. We know that in this case the signal originated from the host.
> remark: Wine unix console is the sole case where launching a GUI program from command line doesn't return immediately to prompt (native & builtin cmd implementation only wait on CUI programs completion). But that's conform to unix behavior.
I'm not sure what exactly you mean by conforming to unix behavior, but it's arguably a bug that will cause problems similar to !3145, under different conditions. I'd rather avoid depending on this behavior in the solution for SIGINT if possible.
> note: I'm not even sure tweeking with setsid whould be useful as anyway the unix console is in raw mode, so only conhost regenerates the signals
It's in raw mode only if a console application reads input. In this case, taking more control by conhost seems justified.

By default, synchronously completed socket operations will still send completions, we currently don't mind that in winhttp. The most essential part is patch 1, which will also avoid stacking those completions. Patch 2 is not strictly necessary since now we indeed shouldn't be getting unexpected completions, but it seems to me it is better not to fully rely on that and skip unexpected ones just in case.

Let The Good Life able to play its intro video, the game creates a source reader from a `http://localhost:6000/<random-hash>` URL. This should also probably work with other games playing streams over http(s).
This is a very basic implementation, using urlmon, and it will download the entire stream to a local temporary file before playback. An more optimized implementation would probably use WinHttp and range requests to partially download the requested stream segments, but this can be implemented in a future change.

This is meant to simplify testing conditions that generally hold true
but may occasionally fail due to interference from external factors
(such as processes that start / stop, network connections being
opened / closed, etc).
The trick is to loop a few times on the set of flaky conditions until
they succeed. During the last attempt all failures are recorded as
usual, while in the previous runs, the tryok() failures area ignored
but cause one more attempt to be made.
The simplest case looks like this:
LOOP_ON_FLAKY_TESTS(3)
{
// ok() failures are never ignored and not retried
ok(..., "check 1", ...);
// tryok() failures are ignored except on the last attempt
tryok(..., "check 2", ...);
}
There is also:
* attempt_retry() which marks the current attempt as failed as if
calling tryok(0), and returns true if another attempt can be made.
* attempt_failed() which returns true if an ok() call failed.
---
This is independent from the 'flaky' mechanism which adds some naming
constraints. The loop macro is still called LOOP_ON_FLAKY_TESTS()
despite being unrelated to the flaky mechanism. The attempt_retry()
and attempt_failed() macro names also don't make it obvious that they
are related to tryok().
I think this mechanism is better than the flaky one because a flaky test
can go bad without anyone noticing, whereas if a tryok() starts failing
systematically it will cause a real failure.
The other side of that coin is that, unlike flaky, the tryok()
mechanism does not entirely eliminate the possibility of getting a
failure, it just reduces it; though by adjusting the maximum number of
attempts one can achieve an arbitrarily low failure rate. For instance
if an ok() call fails 10% of the time and one wants a maximum of 1 in
a million failure rate, use LOOP_ON_FLAKY_TESTS(6). The cost is an
increased run time in the worst case.
This also limits the use of this mechanism to tests that have a
reasonably low failure rate to start with (otherwise one has to loop
too many times). Also note that there are cases where looping
essentially reduce the failure rate to zero. For instance
ieframe:webbrowser fails if IE creates a net session while the test is
counting them. But IE only creates the one net session on start up so
trying even one more time should guarantee that the test will succeed.
Other cases like scheduling delays and the creation of network
connections are more probabilistic in nature. Maybe a comment in test.h
should offer some guideline as to the target failure rate.
Eventually this may replace the flaky mechanism but that depends on
how well it works in practice and how practical it is to loop on flaky
tests. It seems to be going well in the few cases I looked at. But I
think this mechanism has value even if the two end up coexisting
indefinitely.
This MR uses the tryok() in some actual tests for illustration and testing purposes. The final MR will probably split most of those off to separate MRs.

This fixes a bug in wine when running on 9pfs where short reads would occur, causing binaries to be loaded incorrectly. All other filesystems on Linux ignore O_NONBLOCK for regular files, so this should not affect them.
Thanks to Paul Gofman for the advice on this fix.
---
Ref https://gitlab.winehq.org/wine/wine/-/merge_requests/3390 for my original attempt at fixing this, particularly https://gitlab.winehq.org/wine/wine/-/merge_requests/3390#note_40093 which describes the strange situation `O_NONBLOCK` finds itself in on filesystems.
The risk with this MR is that fifo, unix sockets or other special files opened via `open_unix_file` in ntdll will now have changed behaviour - but my quick look suggests that this is unlikely, as `open_unix_file` is only used for:
- `dlls/ntdll/unix/file.c`: `NtCreateFile` and `NtDeleteFile`
- `dlls/ntdll/unix/process.c`: loading PE information and getting a dirfd for the current directory
- `dlls/ntdll/unix/env.c`: `open_nls_data_file`
- `dlls/ntdll/unix/loader.c`: dll load functions
- `dlls/ntdll/unix/registry.c`: `NtLoadKeyEx`

The read and pread syscalls are permitted to return fewer bytes than requested (unlike the fread libc call which will only perform a short read on error or EOF). This is most likely to occur when binaries are located on slower filesystems (e.g. NFS or 9pfs)
ffab9d9 is a relatively recent regression here, but a lot of the code appears to be much older (e.g. the read call in 341b7dc)
In this MR I've focused on ntdll, but I see a lot of similar mishandling of the pread return value in `server/`. I will raise a bug as I don't intend to create a follow up MR at this time.

That's not necessarily the case, is it? Any call to `vkd3d_shader_parser_error()`, such as in `dxil_record_validate_operand_min_count()`, could trigger this failure.
More in general, I think we there is some confusion between whether to use the parser `failed` bit vs using the return value. We could use the same convention as the HLSL compiler: `failed` is set as soon as an error is found, and it should always set via `vkd3d_shader_parser_error()` so that a diagnostic is always available; an error return value should only be used when an error was found and parsing must halt immediately.
In this scheme you should never look at `failed` to decide what to return, because you don't know if `failed` was set because of an error that still allows parsing or not. You have to genuinely propagate the return code at each level.
It is useful to have memory allocation functions that also set the `failed` bit, like the HLSL compiler.

This was already here before, but I just realized that setting `code_block` to `NULL` might give a few problems if there are some other instructions (which shouldn't be there, but the shader might be untrusted input). Specifically, various lines in this loop assume that `code_block` is valid, and if it's not an `assert()` could be triggered.
