t5551 hangs ?

Hej,
I found 2 threads about hanging t5551, one in 2016, and one question from Junio somewhen in 2017.
I have it reproducable here:
- Debian 8, 64 bit
- SSD
- Half-modern processor ;-)

The last thing I can see is:
ok 29 - test allowanysha1inwant with unreachable

A simplified ps -ef shows:
/usr/sbin/apache2 -d /home/blalbla/t/trash directory.t5551-http-fetch-smart/httpd -f /home/blalbla/t/lib-httpd/apache.conf -c Listen 127.0.0.1:5551 -k start /usr/sbin/apache2 -d /home/blalbla/t/trash directory.t5551-http-fetch-smart/httpd -f /home/blalbla/t/lib-httpd/apache.conf -c Listen 127.0.0.1:5551 -k start /usr/sbin/apache2 -d /home/blalbla/t/trash directory.t5551-http-fetch-smart/httpd -f /home/blalbla/t/lib-httpd/apache.conf -c Listen 127.0.0.1:5551 -k start /usr/sbin/apache2 -d /home/blalbla/t/trash directory.t5551-http-fetch-smart/httpd -f /home/blalbla/t/lib-httpd/apache.conf -c Listen 127.0.0.1:5551 -k start /usr/sbin/apache2 -d /home/blalbla/t/trash directory.t5551-http-fetch-smart/httpd -f /home/blalbla/t/lib-httpd/apache.conf -c Listen 127.0.0.1:5551 -k start /usr/sbin/apache2 -d /home/blalbla/t/trash directory.t5551-http-fetch-smart/httpd -f /home/blalbla/t/lib-httpd/apache.conf -c Listen 127.0.0.1:5551 -k start /usr/sbin/apache2 -d /home/blalbla/t/trash directory.t5551-http-fetch-smart/httpd -f /home/blalbla/t/lib-httpd/apache.conf -c Listen 127.0.0.1:5551 -k start /home/blalbla/git -C too-many-refs fetch -q --tags

The tests passes on another box (real old laptop, spinning disk)

Anything that can be done to debug it ?

Hello, Torsten.

I don't think the SSD/regular disk have anything to do with it.

- Are you running tests concurrently? (e.g., with -j x)
- What happens if you run the test individually (i.e., cd t and ./t5551...)
- You probably want to see the version of apache this is running/etc.
- What happens if you kill the apache processes?

I can't reproduce on my side, but let me see if I can dig a little into it.

Cheers!

No concurrency.
That's what I do: ./t5551-http-fetch-smart.sh

The one that comes with Debian -
I am not an expert here, what is it that is interesting ?

I am left with these processes:
/home/blabla/pu/git -C too-many-refs fetch -q --tags /home/blabla/pu/git-remote-http origin http://127.0.0.1:5551/smart/repo.git

Thanks, more tips or things I can do are welcome.
t5551 seems to be flaky - from time to time.
It seems that I have it reproducable unstable, so if someone has more ideas, please.

Oh ok! I was just trying to weed out what could out of place. Just to make sure, your old compute is also running debian 8 latest?

I'm not sure, but sometimes it's helpful to look at changelogs between versions of packages to get a poiner as to what could be wrong. I wonder if it's apache the one that's failing on this case. Probably a paste of dpkg-query --show apache would help me try to reproduce..

So it's probably not an issue with apache, as the socket should be hopefully closed gracefully.

I'm still unable to reproduce. Do you think you can enable GIT_TRACE, GIT_TRACE_PACK and GIT_TRACE_CURL and pastebin/paste what you see?

Cheers!
