inconsistency --smart-prepend vs. date2name stamp

[nbehrnd]

appendfilename functions differently for files stamped by date2name in either default, or --withtime time stamp.

Manual replication:

touch ping.txt
date2name ping.txt

appendfilename 2022-01-06_ping.txt -t new --smart-prepend

to yield

ERROR    Error while trying to build new filename: <class 'TypeError'>
ERROR    1 error(s) occurred. Please check output above.

An analogue programmatic replication with the test script approach (just submitted, incomplete coverage, under construction) with pytest/pytest-3 for Python3:

pytest-3 test_appendfilename.py -m "smart" -v

File 2021-12-31T18.48.22_test.txt is processed as 2021-12-31T18.48.22 book test.txt and thus successfully removed by the test script. However, test file 2021-12-31.txt is processed to 2021-12-31 book txt loosing the period en face of the file extension. (File test.txt is processed by appendfilename to book test.txt, thus indicating appendfilename works fine on this one.).

En route to extend the test script's scope (there is revised deposit in the pull request), the scene is more complex than anticipated earlier.

• Xubuntu 20.04.2 LTS/Fossa, live image with addition of pytest for Python3 (Python 3.8.5, bash 5.0.17(1)): no problem to run appendfilename on any of the three test files 2022-01-07T18.48_test.txt, 2022-01-07_test.txt, or test.txt manually on the CLI, no problem to run all the automated tests. To select only those about --smart-prepend, either one of the two instructions below work well:

pytest-3 test_appendfilename.py -m "smart"
pytest-3 test_appendfilename.py -m "smart" -v  # a more verbose report to the CLI

• Debian 12/bookworm, branch testing: Testing via test script (same instructions as for Xubuntu 20.04.2 LTS/Fossa) works without a problem. Only the direct.manual interaction on the CLI is inconsistent for either one of the two with date2name's default / --withtime time stamp. Perhaps the appendfilename's log when in the verbose mode helps to narrow the cause? If relevant, this session with Python 3.9.9 and bash 5.1.12.

Hi @nbehrnd, Unfortunately, I can't reproduce the issue at my side and the debug output is not showing me something that helps me here.

I just committed a more verbose debug output for that use-case. For comparison, this is my output:

Can you please re-run your test and post here the output? Thank you very much!

By observation, now the manual conversion works (both on Xubuntu 20.04.2 LTS Fossa, as well as on Debian 12/book worm [testing]). Conceptually, the extended log to the CLI matches yours:

So, this obstacle is out of the way. Thank you!

Weird.

Well, thanks for your effort in any case. Let me know when this reappears. I keep the additional debug code for now.
