Version: 1.0.1
Python-3.9
FreeBSD 13.2

[BR1py]

First I must try to reproduce, the issue not seen on WindowsOS and Linux Ubuntu (see Actions e.g.: https://github.com/BR1py/itertree/actions/runs/5365735791/jobs/9734740652).

[BR1py]

Sorry I tried to reproduce but I did not get any VM or online FreeBSD working. Do you have any advice here? Also the GIT workflows do not support the target.

[yurivict]

Here are step-wise instructions on how to reproduce this problem:

1. Install the FreeBSD VM image into VirtualBox.
2. Boot FreeBSD
3. Install git: pkg install git
4. Check out the ports tree: git clone https://git.FreeBSD.org/ports.git /usr/ports
5. cd /usr/ports/devel/py-itertree
6. Install dependencies: pkg install -A make missing
7. Build: make
8. Run tests: make test

[BR1py]

I ran the following test with success:

install via pip:

pip install pytest
pip install itertree

Create a clone of the git itertree repository
and switch in the folder itertree/tests.

I executed with success:

python -m pytest test_itertree_full_feature_trees.py

I guess the issue comes only up if the proposed workflow is used (maybe because the make file is missing). I will check this.

[BR1py]

I tried now the same workflow you proposed. Again I cannot reproduce the issue. Can you please retest? I have no idea why it did not work for you.

[yurivict]

There are intermittent failures. I ran the testsuite several times and it succeeded. But now I got this error:

*** Error code 1

Version: 1.0.1
Run in the FreeBSD ports tree.

[BR1py]

During the tests some files are created in the folder /tmp in the tests folder of the installation. Can it be that those files get corrupted if they are created inside the ports structure?
For the next releases I will create those files in Linux like OS in the folder /tmp/itertree_test.
I hope this change makes the test execution on FreeBSD stable.

[BR1py]

Can you please retest with newest release where the storage behavior was changed.

[yurivict]

@BR1py
Do you know why does setup.py still have version=1.0.1 here?

[BR1py]

I made a misstake in the pull request for version 1.0.3 please give Version 1.0.5 a try.

[yurivict]

1.0.5 still has this failure:

[spaciouskarter78]

I'm having a similar error with one of the tests while making a Debian package on Debian 13.

[BR1py]

Can you please recheck if the issue is still seen with Release 1.2.0? I made some fixes related to the test setup, especially for newer Python versions.
