Today I tried to upgrade outdated ports but got an error when upgrading python310(universal)

Then I uninstalled, cleaned and installed python310 again but also failed.

sudo port uninstall python310
Note: It is not recommended to uninstall/deactivate a port that has dependents as it breaks the dependents.
The following ports will break:

 py310-markupsafe @2.1.1_0

Finally I uninstalled all ports on my mac and only install python310+universal, but met the same issue.

log of installing python310

[water137780117]

remove all ports and only install python

[jmroot (Joshua Root)]

That's very strange; the build succeeded on all the buildbot platforms and for me locally. Are you building on a case-sensitive or case-insensitive filesystem? Is the executable in the worksrcdir python.exe or python? And what are the permissions on it?

[water137780117]

It seems there is something wrong with the latest Portfile /opt/local/var/macports/sources/mirrors.tuna.tsinghua.edu.cn/macports/release/lang/python310/Portfile.
I replaced it with the previous version ​https://github.com/macports/macports-ports/blob/7543522fd8fb8dfe8121875bbf21c9ea750f4ef1/lang/python310/Portfile.
Then the error disappeared.

The executable file and the its permission is

$ ls -la |grep python
-rw-r--r--    1 macports  wheel  44582112 May 10 19:30 libpython3.10.a
-rw-r--r--    1 macports  wheel      2094 May 10 19:27 python-config
-rw-r--r--    1 macports  wheel      2094 May 10 19:27 python-config.py
-rwxr-xr-x    1 macports  wheel    115655 May 10 19:31 python.exe
-rw-r--r--    1 macports  wheel     65722 May 10 19:27 python.exe-gdb.py

python310-3.10.4_0 can be installed correctly while python310-3.10.4_0 can't. It seems the only diffrence is the Portfile (/opt/local/var/macports/sources/mirrors.tuna.tsinghua.edu.cn/macports/release/lang/python310/Portfile).

[jmroot (Joshua Root)]

Reverting the Portfile will give you a broken universal build. The change was made to fix #63782.

[jmroot (Joshua Root)]

OK, so you do have python.exe, but the failed command is trying to run ./python. That means the file exists call on line 150 of the current Portfile must be returning false despite the file existing?

[jmroot (Joshua Root)]

add debug output to python310 Portfile

[jmroot (Joshua Root)]

Would you be able to apply the attached patch to the Portfile in order to add some extra output to help debug this?

I'm willing to help debug, but failed to patch the file...

$ sudo patch ./Portfile ./debug-output.diff -b
Password:
patching file ./Portfile
Hunk #1 FAILED at 150.
1 out of 1 hunk FAILED -- saving rejects to file ./Portfile.rej

Did I patch the file in a wrong way?

[jmroot (Joshua Root)]

Make sure you have the very latest version of the file, it has been changed quite recently.

[jmroot (Joshua Root)]

For reference:

% wc lang/python310/Portfile   
     263     777    9693 lang/python310/Portfile
% openssl dgst -sha256 lang/python310/Portfile

I fetched the latest Portfile and successfully installed python310@3.10.4_1 even without patching the file. I also tried to reinstall after patching the file and successfully installed the package as well. The log file disappeared after finishing installation. Do I need to provide some additional files?

[jmroot (Joshua Root)]

Did you perhaps install from a binary this time? If so, you can run sudo port destroot python310 to force a local build.

[water137780117]

The attachment destroot after patching.log​ is the main.log I got after executing sudo port destroot python310.

[jmroot (Joshua Root)]

OK, thanks. That seems to have worked fine. I guess we can call this fixed despite not knowing why it broke or what un-broke it. :)
