Hi, Sunpoet!

Can you confirm that this is the latest (4.10.11) version of the port?

As it has:

USES+=                          python:3.4+
PLIST_SUB+=                     SAMBA4_PYTHON=""
SUB_LIST+=                      SAMBA4_PYTHON=""
CONFIGURE_ARGS+=                --nopycache

Which supposed not to generate any pycache files.

Hi Timur, 

Yes, It's the latest verision. I put the log on https://people.FreeBSD.org/~sunpoet/temp/samba410-4.10.11.log
Comment 3 Andrew Fyfe 2020-02-02 14:37:44 UTC
I only have this issue when running poudriere bulk with the -t option (Add some testing to the specified ports), without the -t option the port builds without issue.

It seems poudriere only checks filesystem violations when -t option is used.

I've prepared two log with/without poudriere -t option.

I feel really dumb here, as I still can't get it reproduced... Maybe, I incidentally fixed it or that error requires some additional configuration to be spotted...

# # poudriere bulk -t -j FreeBSD-12_1-amd64 -p devel -z samba net/samba410

If it's still not fixed... Maybe you can find the solution in your setup, as I, seems, can't reproduce it.

Potential fix should be placing PYTHONDONTWRITEBYTECODE=1 in the environment on the appropriate stage(build, install, test).

At the moment I don't see where to look :(
Comment 6 Matthias Andree freebsd_committer 2020-09-20 20:15:40 UTC
I also see this issue. Timur, have you tried poudriere bulk -t net/samba410? Do you have special make.conf options, or nondefault Python 3.7 configuration?
Comment 7 Matthias Andree freebsd_committer 2020-09-20 20:21:13 UTC
I think this is also an indication that the tevent module was used at run-time during the build.  Possibly we have differences in privileges of the build, or paths, or it's an indication that the build might want to use

-B     : don't write .pyc files on import; also PYTHONDONTWRITEBYTECODE=x

(i. e. run ${PYTHON_CMD} -B ..., or export PYTHONDONTWRITEBYTECODE=x to the environment)

Hi, Matthias!

I'm pretty sure that tevent gets called at some stage of the build that leads to .pyc file. But I, seems, can't find when it happend.

Indeed, my setup is not standard - I use host system /usr/ports inside poudriere.

Also, at the moment it is set to use Python 3.8(for the test purposes), but the same I couldn't reproduce the problem with 3.6 either.

Port now has:

# Don't cache Python modules
CONFIGURE_ARGS+=                --nopycache
TEST_ENV+=                      PYTHON="${PYTHON_CMD}" \
                                SHA1SUM=/sbin/sha1 \
                                SHA256SUM=/sbin/sha256 \
                                MD5SUM=/sbin/md5 \

And still produces bytecode.

I was wondering, would it be sufficient just to `rm -f` the .pyc file in the post-install section or that still would indicate the FS violation?
Comment 9 Sunpoet Po-Chuan Hsieh freebsd_committer 2020-10-15 19:24:02 UTC
Samba 4.12 is the new default and here's the result of poudriere with "-t" flag.

(In reply to Timur I. Bakeyev from comment #8)

While building tevent, can you generate the .pyc files and add them to the PLIST?
It should be similar with ports r550817.
Comment 10 Sunpoet Po-Chuan Hsieh freebsd_committer 2020-11-24 20:59:06 UTC
Hi Timur,

Please try this patch [1]. It fixes the filesystem violations which building samba412. I guess it should also work with other samba versions.
