Help! "fork: permission denied" error 13

[Pete Burkindine]

Help!

All of a sudden, without any change to my system, I cannot rebase. 

* I've uninstalled and reinstalled Git for Windows a couple of times, the second installed into my User folder.

* It doesn't matter which repo I'm in.

* It does it in freshly cloned repos, too.

* I gave Authenticated Users full rights on both the Git folder and the repo folder.

Here is the error, which I've had no luck finding information about...

 $ git rebase -i HEAD~3

      0 [main] sh 8284 fork: child -1 - CreateProcessW failed for 'C:\Users\pburkindine\Git\usr\bin\sh.exe', errno 13

/mingw64/libexec/git-core/git-rebase--interactive: fork: Permission denied

    164 [main] sh 5964 fork: child -1 - CreateProcessW failed for 'C:\Users\pburkindine\Git\usr\bin\sh.exe', errno 13

/mingw64/libexec/git-core/git-rebase--interactive: fork: Permission denied

/mingw64/libexec/git-core/git-rebase--interactive: line 126: + : syntax error: operand expected (error token is "+ ")

Please help!  I can't work!

Thanks,

Pete

This sounds like a case for the BLODA ("Big List Of Dodgy Apps"):

https://cygwin.com/faq/faq.html#faq.using.bloda

If you are confused why I refer you to Cygwin: part of Git (e.g. rebase
-i) is implemented as shell script, and to support running those, we use
MSYS2's Bash, which uses the MSYS2 runtime to provide a POSIX emulation
layer, that in turn is a slightly modified Cygwin runtime.

Now, to find out whether you have such a dodgy application messing with
your rebase, open a `cmd` and run

set CYGWIN=detect_bloda
C:\Users\pburkindine\Git\usr\bin\sh.exe --login -i

This should help diagnose things further. For my own education, may I ask
to report back your findings?

Ciao,

Hi, Johannes,

Thanks for the reply.

Unfortunately, the response was not very revealing:

Got up with our IT, you are correct, it was caused by an update to Cylance

Hey Johannes,

I know I'm resurrecting a thread from 2016 but I found your post on Google and I can't imagine anyone could be more helpful than you as I think I'm having the exact same error Pete had.

So, "for your own education", as you mentioned, here's what I get after running the commands you suggested to Pete:

C:\bin\git>bin\sh.exe --login -i

     84 [main] bash 5548 C:\bin\git\bin\..\usr\bin\bash.exe: *** fatal error in forked process - MapViewOfFileEx '(null)'(0x140), Win32 error 5.  Terminating.

      0 [main] bash 13036 fork: child 5548 - died waiting for dll loading, errno 11

bash: fork: retry: Resource temporarily unavailable

    714 [main] bash 3252 C:\bin\git\bin\..\usr\bin\bash.exe: *** fatal error in forked process - MapViewOfFileEx '(null)'(0x140), Win32 error 5.  Terminating.

1394765 [main] bash 13036 fork: child 3252 - died waiting for dll loading, errno 11

bash: fork: retry: Resource temporarily unavailable

    419 [main] bash 9648 C:\bin\git\bin\..\usr\bin\bash.exe: *** fatal error in forked process - MapViewOfFileEx '(null)'(0x140), Win32 error 5.  Terminating.

3792152 [main] bash 13036 fork: child 9648 - died waiting for dll loading, errno 11

bash: fork: retry: Resource temporarily unavailable

...This goes on ad eternum until I hit Ctrl+C, which then results in the line below followed by a seemingly workable shell, as you can attest from the results of running "ls"

bash: fork: Resource temporarily unavailable

bash-4.4$ ls

LICENSE.txt         bin  etc           mingw64               tmp           unins000.msg

ReleaseNotes.html   cmd  git-bash.exe  mintty.exe.stackdump  unins000.dat  usr

bash.exe.stackdump  dev  git-cmd.exe   proc                  unins000.exe

bash-4.4$

On the off chance that you (or anyone else) have an idea as to what to do next, I'd deeply appreciate the help.

Best,

Andy

Could you re-run this after setting...

Thanks,
Johannes

[Andre Terra]

Johannes,

Sorry, I should have been clearer. I has already set CYGWIN to detect_bloda at that point, so the output you see in my original message is what happens after set CYGWIN=detect_bloda

Thanks again for helping with this.

Best,

Andy
