1# Test data for `test_zipfile`, `test_tarfile` (and even some others) 2 3## `test_zipfile` 4 5The test executables in this directory are created manually from `header.sh` and 6the `testdata_module_inside_zip.py` file. You must have Info-ZIP's zip utility 7installed (`apt install zip` on Debian). 8 9### Purpose of `exe_with_zip` and `exe_with_z64` 10 11These are used to test executable files with an appended zipfile, in a scenario 12where the executable is _not_ a Python interpreter itself so our automatic 13zipimport machinery (that'd look for `__main__.py`) is not being used. 14 15### Updating the test executables 16 17If you update header.sh or the testdata_module_inside_zip.py file, rerun the 18commands below. These are expected to be rarely changed, if ever. 19 20#### Standard old format (2.0) zip file 21 22``` 23zip -0 zip2.zip testdata_module_inside_zip.py 24cat header.sh zip2.zip >exe_with_zip 25rm zip2.zip 26``` 27 28#### Modern format (4.5) zip64 file 29 30Redirecting from stdin forces Info-ZIP's zip tool to create a zip64. 31 32``` 33zip -0 <testdata_module_inside_zip.py >zip64.zip 34cat header.sh zip64.zip >exe_with_z64 35rm zip64.zip 36``` 37
