# Test data for `test_zipfile`
|
||
|
|
|
||
|
|
The test executables in this directory are created manually from header.sh and
|
||
|
|
the `testdata_module_inside_zip.py` file. You must have infozip's zip utility
|
||
|
|
installed (`apt install zip` on Debian).
|
||
|
|
|
||
|
|
## Purpose
|
||
|
|
|
||
|
|
These are used to test executable files with an appended zipfile, in a scenario
|
||
|
|
where the executable is _not_ a Python interpreter itself so our automatic
|
||
|
|
zipimport machinery (that'd look for `__main__.py`) is not being used.
|
||
|
|
|
||
|
|
## Updating the test executables
|
||
|
|
|
||
|
|
If you update header.sh or the testdata_module_inside_zip.py file, rerun the
|
||
|
|
commands below. These are expected to be rarely changed, if ever.
|
||
|
|
|
||
|
|
### Standard old format (2.0) zip file
|
||
|
|
|
||
|
|
```
|
||
|
|
zip -0 zip2.zip testdata_module_inside_zip.py
|
||
|
|
cat header.sh zip2.zip >exe_with_zip
|
||
|
|
rm zip2.zip
|
||
|
|
```
|
||
|
|
|
||
|
|
### Modern format (4.5) zip64 file
|
||
|
|
|
||
|
|
Redirecting from stdin forces infozip's zip tool to create a zip64.
|
||
|
|
|
||
|
|
```
|
||
|
|
zip -0 <testdata_module_inside_zip.py >zip64.zip
|
||
|
|
cat header.sh zip64.zip >exe_with_z64
|
||
|
|
rm zip64.zip
|
||
|
|
```
|
||
