Installer freezes at end of installation

[WasabiFan]

When I run the Git for Windows 2.6.4 installer, the progress bar apparently indicates that the installation has completed (or is close to completing) but the installer never finishes. This seems very similar to the behavior in #351, but I do not have any custom scripts in my .profile or .bashrc (I don't even have either of those files in my user folder).

The installer process owns a conhost.exe instance which is using ~20% of my CPU. I let it run for around 4 hours, but it was pretty obvious that it wasn't coming back.

I'm on Windows 10 x64 (11082).

I should also mention that the console instance is currently running C:\Program Files\Git\post-install.bat.

Any idea which commands are run inside the post-install.bat?

Hint: There are a number of shell scripts in /etc/post-install/ that are run in order. The first one, 01-devices.post, for example, tries to create a couple of files/directories in /dev/. If /dev/mqueue and /dev/fd both exist, therefore, it would be a good indicator that this script has finished. Likewise, manual inspection of the other files in /etc/post-install/ should give you a pretty good idea what the scripts are supposed to do and to diagnose where things start to hang.

After re-running it just now and giving it around an hour, there is no dev directory at all -- so I'd say it is somewhere before that. Where, exactly, I can't tell; the installer's log files don't include any information about the post-install.

When I kill the installer process and then manually run the post-install.bat script from an admin command prompt, it spews a bunch of errors about access denied -- but nonetheless it creates the /dev directory and the files within, so I am pretty sure that I am not accurately recreating the conditions of the installer.

it spews a bunch of errors about access denied

Would there be a chance to see the exact text it spews out?

Here's the console log. I did this from an admin CMD window after killing the installer process and rebooting, having given it half an hour from when the bar hit the ~100% mark.

Or, just running the last line of post-install (after cleaning the directory and re-running the installer):

C:\Program Files\Git>@usr\bin\bash.exe --norc -c "export PATH=/usr/bin:$PATH; export SYSCONFDIR=/etc; for p in $(export LC_COLLATE=C; echo /etc/post-install/*.post); do test -e \"$p\" && . \"$p\"; done"

'C:\\WINDOWS\\System32\\drivers\\etc\\services' -> '/etc/services'
'C:\\WINDOWS\\System32\\drivers\\etc\\networks' -> '/etc/networks'

But again, it doesn't do the same thing when the installer is running itself. The dev directory is not created when the installer runs, but it is when I run it.

I guess we will have to find a way how to redirect the output of this batch file into the install log when called with /LOG=<path> option (probably by using/querying {log}).

I implemented that a long time ago.
