Apache Fork Errors - Found on Windows Server 2019

Apache Fork Errors - Found on Windows Server 2019

[OwN-3m-All]

Hi All,

I can't seem to get apache via cygwin to work on Windows Server 2019.

Here is my error log:

I issued the "rebase-trigger fullrebase" command and ran the cygwin setup
for it to rebase.  I rebooted the server, and that didn't make a difference.

Any idea why this is happening or how to fix it?

Makes sense to have tried that; thanks for reporting outcome.

Been a long time since I've run Apache and that wasn't even on Cygwin, but...
Apache had/has two run modes, pre-forking and threaded.  It appears you're running 
it in pre-forking mode.  Try running it in threaded mode.  This might be 
controlled by httpd.conf or some other Apache config file.

If somebody else on the list is successfully running Apache on Cygwin, maybe they 
can chime in on which mode they're using.
HTH,

This might be controlled by httpd.conf or some other Apache config file.

That is doable, but changing it makes it so that PHP no longer works.

To make that change, you just comment out the mpm_prefork.so line and
uncomment the mpm_worker.so line to change the mode in httpd.conf:

#LoadModule mpm_prefork_module modules/mod_mpm_prefork.so
LoadModule mpm_worker_module modules/mod_mpm_worker.so

But then, PHP no longer works, so that doesn't really help in this
situation, as I must have PHP working.  I believe the pre-forking mode used
to work previously.  I'm trying to test this in Windows 7 and 10 to confirm.

Notice how _all_ images are mapped to the same (extremely low) address
even though they seem to be rebased properly as evidenced by their
address in the parent process.  I suggest you disable whatever BLODA
thinks it's a good idea to inject itself into Cygwin processes.

Such as?  This is a fresh install of Windows Server 2019 with no additional

Re: Apache Fork Errors - Found on Windows Server 2019

[OwN-3m-All]

I checked, and I'm not running anything listed here:

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

I even disabled Windows Defender to see if that would make a difference,
but it didn't.

Results in a fresh install of Windows 10 Pro N 21H1 19043.928 are similar:

Windows 7 has issues too with the latest Cygin and packages:

For one, in Windows 7, the command of "ash.exe /bin/rebaseall" never
finishes.

It looks like Apache is broken across all versions of Windows.  I'm not
sure when this got broken, but I know it used to work without these issues.

Re: Apache Fork Errors - Found on Windows Server 2019

Downgrading (choosing lower versions) httpd and httpd-mod_php7 didn't
help.  Same issue.  It appears to be something cygwin specific and not
package related?  I don't know...

Running the httpd command under strace might provide a clue.  See if you see any 
unexpected DLLs being loaded.

Hopefully I can strace at some point soon and get back to you with the
results.

I have multiple confirmed reports from other people that this no longer
works though.  And again, I tried it on three different fresh installs of
different Windows operating systems (with no bloatware or BLODA), and all
of them had the same issue.

Greetings, OwN-3m-All!

My question is tangential to Cygwin: why can't you run native Apache with
native PHP? What Cygwin specific is in your needs?

> Any idea why this is happening or how to fix it?

cygcheck <given_exe_or_dll> may provide a clue.

I have one other thought.  There was a recent packaging change in harfbuzz and 
freetype2 that introduced a circular dependency between the two:

   https://cygwin.com/pipermail/cygwin/2021-September/249316.html
   https://cygwin.com/pipermail/cygwin/2021-September/249317.html

Since those are the two DLLs that are causing a problem for you, maybe that 
circular dependency doesn't work well on Cygwin for some reason.  Please try 
downgrading to the previous versions of harfbuzz and freetype2 and see if that 
fixes the problem.

Is /etc/postinstall/0p_000_autorebase.dash rebase completing 
successfully after the new installs?

Maybe check and/or attach the cygwin install log /var/log/setup.log.full 
for dependency, install, or postinstall errors, and run

	$ rebase -is > /var/log/rebase-is.log

on one of those systems and attach the log.

Is there a patch, update, or GP enabling ASLR on all processes?

That did fix the problem!  I downgraded both and restarted, and now apache
and php works again.  Can that change be reverted or fixed so that it
doesn't happen on future installs?

Just to double check, could you upgrade harfbuzz and freetype2 again and see if 
the problem comes back?  Make sure that there are no Cygwin processes running 
and that the _autorebase postinstall script completes successfully.  (You can 
check /var/log/setup.log.full for rebase messages.)

Yes, I'll revert that change if you can confirm as above that this really is the 
problem.

I upgraded both libharfbuzz0 and libfreetype6 to the latest version again,
and the issues are back.

I tested these previous versions for both, and they work:

libharfbuzz0 2.7.4-1 and 2.8.1-1 work
libfreetype6 2.10.4-1 and 2.10.4-2 work

The latest versions of these libs need to be reverted or properly fixed.

The new packages (using the previous build method, with no circular dependency) 
are now available.  Please test.

I just tried the new packages (using the previous build method, with no
circular dependency), and it appears that everything is working properly
again.

Thank you!
