Git Bash Errors in 2.7.0.2

[strohm-a]

I installed Git 2.7.0 for Windows over 2.6.0 on 64-bit Windows 8 and I get the following output when I run bash.exe or sh.exe:

      0 [main] bash 2836 fork: child 2900 - died waiting for dll loading, errno 11 
bash: fork: retry: No child processes

15661014 [main] bash 2836 fork: child 5760 - died waiting for dll loading, errno 11
bash: fork: Resource temporarily unavailable

Running git-bash.exe gives the following output:

mkdir: cannot create directory '/dev/shm': Read-only file system

rm: cannot remove '/etc/post-install/99-post-install-cleanup.post': Permission denied

I can correct the second issue by running git-bash.exe as administrator once.

If I replace 2.7.0 with 2.6.0, the problems go away.

A co-worker is having the same problem on a new 64-bit Windows 7 computer as well.

Thanks for this very thorough bug report.

Could you install 2.7.0(2) again, then run a cmd as administrator, and run these commands:

cd C:\Program Files\Git\usr\bin
dash -c 'rebaseall -p'

This is of course only a shot in the dark, but your report reminded me of the 32-bit issues we had. Maybe they now affect 64-bit as well.

Thanks for the help. The response to the dash command is:

dash: 1: rebaseall: not found

This is strange though because rebaseall is in that directory.

Edit:

After reading the linked article, I tried the following command:

C:\Program Files\Git\usr\bin> dash -c '/usr/bin/rebaseall -p'
dash: 1: /usr/bin/rebaseall: Permission denied

This was run from an administrator command prompt.

[dscho]

Actually, you were so close: dash -c './rebaseall -p' should get you somewhere.

I have the same issue - unfortunately, I still get the Permission denied error when running from /usr/bin.

[mhils]

FWIW, I was able to solve this by repeatedly running git-bash.exe --no-needs-console --no-cd --command=post-install.cmd in C:\Program Files\Git. The setup routine got stuck when I reinstalled Git for Windows, I unfortunately don't remeber if that has been the case the first time as well.

[dscho]

I still get the Permission denied error when running from /usr/bin.

If you installed to C:\Program Files\Git (the default), then you have to run the command as administrator.

[mhils]

@dscho, I got the "Permission denied" error running the command as administrator (yes, I triple-checked ;-) ).
Nonwithstanding, I could solve that using the commands in my previous post.

[dscho]

@mhils ah, well, you were a bit sparse with your info. You mentioned only that there are Permission denied errors. There are permission denied errors that are 1) legitimate and 2) harmless: chown will have problems because it assumes POSIX permissions and cannot handle Windows ACLs.

Take-home lesson: be generous in the information you provide and the output you copy & paste.

[strohm-a]

I was also getting the permission denied error while running the rebaseall command as an administrator.

I have noticed that 2.7.0(0) works, while 2.7.0(1) and later does not. I'm wondering if the ASLR support has something to do with this problem. I did a little research and https://en.wikipedia.org/wiki/Address_space_layout_randomization#Microsoft_Windows states that HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\MoveImages must be enabled for ASLR to work. Both my and my co-workers' machines are IT controlled and neither has this registry entry.

Another thought is that our IT-supplied anti-virus (Cylance) is preventing the rebase from working.

[dscho]

I was also getting the permission denied error while running the rebaseall command as an administrator.

Aaaargh! Again no context? Just mentioning that there was some permission denied error?

I'll bow out of this ticket.

[strohm-a]

All of the context is in my previous comment from four days ago, but I will copy it here for you:

After reading the linked article, I tried the following command:

C:\Program Files\Git\usr\bin> dash -c '/usr/bin/rebaseall -p'
dash: 1: /usr/bin/rebaseall: Permission denied

This was run from an administrator command prompt.

The linked aticle is the 32-bit issues articly you mentioned. I can't offer any additinoal context because the rebase command isn't returning any.

[dscho]

After reading the linked article, I tried the following command:

C:\Program Files\Git\usr\bin> dash -c '/usr/bin/rebaseall -p'
dash: 1: /usr/bin/rebaseall: Permission denied

If you read your initial report, you will see plenty of "Permission denied" errors there. So simply referring to "permission denied errors" later (and not mentioning at all that the dash invocation produced them) was prone to be confusing. You will have to admit so much.

As it is, I think dash -c './rebaseall -p' is more likely to work, but I am still hoping that somebody else is willing to help out in this ticket.

[strohm-a]

Thank you for the help. With Git for Windows version 2.7.1, I ran the following command from an administrator command prompt:

C:\Program Files\Git\usr\bin> dash -c './rebaseall -p'
dash: 1: ./rebaseall: Permission denied

I'm sorry I cannot provide any additional context. This is all that is returned by the command. I appreciate the help you have provided so far.
