@remilapeyre thanks for your review, I will send a new commit when I solve these issues.

Hi @hakancelik96, thanks for updating the rest of the module!

It looks like there is some merge conflicts, could you fix these? I think running make regen-all should do it :)

@remilapeyre Thanks for reviewing. I resolved syntax issues.

Thanks for fixing the syntax issues @hakancelik96, please have a look at the compilation errors:

I'll send a new PR with a clear history

Don't worry too much about the history, everything will be squashed anyway and it's normal to write corrections for a PR.

I'll send a new PR with a clear history

Any link to that PR? Or can you say if you are not working on it anymore?

@audeoudh I am not working on anymore.

I've made the few additional changes to those in this PR. When I work out the issues, I'll make a new PR. I took out an attempt with path_t. However, here is why I think argument clinic (or something else?!) is actually intercepting the attempted call:

With my temporary debugging, I have this function in Modules/_gdbmmodule.c:

[clinic start generated code]*/

static PyObject *
dbmopen_impl(PyObject *module, PyObject *filename, const char *flags,
             int mode)
/*[clinic end generated code: output=9527750f5df90764 input=812b7d74399ceb0e]*/
{
    PyObject_Print(filename, stdout, 0);
    printf(" from _gdbmmodule.c (XXX)\n");
    /* ... rest of function ...*/

And I have a very simplified test script:

import _gdbm
import sys
from pathlib import Path

print(sys.version)
path = '/tmp/tmp.db'

db = _gdbm.open(path, 'c')
print("Opened with string path")
db.close()

db = _gdbm.open(Path(path), 'c')
print("Opened with path-like")
db.close()

The output of running this is:

3.11.0a0 (heads/[bpo-45133](https://bugs.python.org/issue45133)-dirty:0376feb030, Sep  8 2021, 00:39:39) [GCC 10.3.0]
'/tmp/tmp.db' from _gdbmmodule.c (XXX)
Opened with string path
Traceback (most recent call last):
  File "/home/dmertz/tmp/pathlike-dbm.py", line 12, in <module>
    db = _gdbm.open(Path(path), 'c')
         ^^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: open() argument 1 must be str, not PosixPath

So before I get to the first line of the _gdbm.open() function, the TypeError is already occurring when passed a PosixPath.
