Pacman Retrieving packages error with QueryUnbiasedInterruptTime function call

[rvasin]

Hello,

I upgraded to the latest version pacman 5.1.3-1 and the latest version of msys-runtime

After running command: pacman -Syu
It does connectly sync the database then it shows:

:: Proceed with installation? [Y/n]
:: Retrieving packages...
2 [main] pacman 192 C:\Programs\msys32\usr\bin\pacman.exe: *** fatal error - couldn't dynamically determine load address for 'QueryUnbiasedInterruptTime' (handle 0x762E0000), Win32 error 127

Yes I see this but still don’t understand what happen. Downgrading pacman and msys2-runtime not solve problem for me. So need to look

[genezx]

Me too. After pacman -Syu today on Win7, pacman is broken.

Debugging shows msys-2.0.dll is trying to load function QueryUnbiasedInterruptTime from kernelbase.dll which only exists in kernel32.dll in Windows 7.

@rvasin @genezx this is from autoload.cc:

/* MSDN claims these are exported by kernel32.dll, but only
   QueryUnbiasedInterruptTime actually is.  The others are only
   available via KernelBase.dll. */
LoadDLLfunc (QueryInterruptTime, 4, KernelBase)
LoadDLLfunc (QueryInterruptTimePrecise, 4, KernelBase)
LoadDLLfunc (QueryUnbiasedInterruptTime, 4, KernelBase)
LoadDLLfunc (QueryUnbiasedInterruptTimePrecise, 4, KernelBase)

I dont have any of this functions in kernelbase under my Windows 7.
Maybe something changed in Windows with updates...

Fixed msys2-runtime uploaded, also created new MSYS2 installers

[rvasin]

For everyone in this situation: it's needed to download the latest version of msys2-runtime? How to do it correctly way? Pacman does not download it because of the error. Thus the only way is to manually download zip of msys2-runtime and extract it? Or there is more correct way to do it?

@rvasin @genezx this is from autoload.cc:

/* MSDN claims these are exported by kernel32.dll, but only
   QueryUnbiasedInterruptTime actually is.  The others are only
   available via KernelBase.dll. */
LoadDLLfunc (QueryInterruptTime, 4, KernelBase)
LoadDLLfunc (QueryInterruptTimePrecise, 4, KernelBase)
LoadDLLfunc (QueryUnbiasedInterruptTime, 4, KernelBase)
LoadDLLfunc (QueryUnbiasedInterruptTimePrecise, 4, KernelBase)

I dont have any of this functions in kernelbase under my Windows 7.
Maybe something changed in Windows with updates...

I never see other 3 functions and only QueryUnbiasedInterruptTime in kernel32.dll.
And any of the all 4 functions is never in kernelbase.dll.
Every version from 6.1.7601.17514 to 6.1.7601.24441.
So it's not update issue.

And the latest MSDN is correct. I don't know who wrote the misleading comments in the code.

[Alexpux]

Fixed

[rvasin]

What is the simplest way to repair the installation?
Installing previous version pacman -U msys2-runtime-3.0.6-1-i686.pkg.tar.xz does not work.
Besides instructions given in https://github.com/msys2/msys2/wiki/MSYS2-reinstallation

[Alexpux]

Well you can manually download 3.0.7-3 msys2-runtime package and unpack Msys-2.0.dll then upgrade packages to latest as usual

[rvasin]

Well I downloaded msys2-base-i686-20190524.tar.xz
and from that archive I copied \msys32\usr\bin\msys-2.0.dll to the same folder in my Windows: \msys32\usr\bin
It replaced old msys-2.0.dll by this new one. Then running
pacman -Syuu
correctly installed 3.0.7-3 msys2-runtime and pacman over it.
So it did work well. Thank you.

But after restart now it shows the messages:

But this is another story (not related to the issue).
I corrected it by removing both packages using:
pacman -R mingw-w64-i686-gcc-ada mingw-w64-i686-gcc-objc
and then running again pacman -Syuu

Seeing this too, thanks for looking into it. Has this been reported upstream in cygwin?
