Which Python pgAdmin builds against and ships has until now been settled in three unrelated places. On Windows, Make.bat used whatever %PGADMIN_PYTHON_DIR% pointed at, which the buildfarm's Jenkins node configuration injected, and then derived the embeddable distribution it actually ships from that interpreter's own sys.version. On macOS, pkg/mac/build.sh defaulted to a version of its own whilst the workflows overrode it with a third, copied from the buildfarm's DEFAULT_PYTHON_VERSION. Locally it was whatever the developer happened to have. A single commit could therefore ship different interpreters on different platforms with nothing anywhere announcing it, which nearly happened: a workflow that discovered Python from the PATH would have shipped 3.14 on Windows against 3.13 on macOS. The version now lives in pkg/python-version.txt, which every platform's packaging reads. It is a file in the tree rather than a GitHub variable because a local build has to read it too, and because a change of interpreter should arrive as a commit somebody can review rather than as a settings change made on an agent. The format is KEY=value with # comments, dull on purpose: it has to be parsed by a batch file, by a shell script and occasionally by a person, and anything richer would need a parser in at least one of those. It carries both the exact CPython version and the python-build-standalone release tag, since that project's releases are dated rather than versioned and the archive names embed both. Make.bat no longer depends on an installed Python at all. It downloads the relocatable distribution named in that file, unpacks it into the build tree and installs virtualenv into it, then fetches the matching embeddable distribution from python.org for what actually ships, so the two can no longer disagree. python-build-standalone suits the signing host particularly well, being a plain tarball rather than an installer and so raising no UAC prompt, which matters because an elevation dialog in that machine's auto-logged-in session waits forever for somebody who is not there. curl.exe and tar.exe have shipped in Windows since 1803, so nothing needs installing to bootstrap it. Both Windows workflows consequently lose their Python setup, and the signing host needs neither a Python, nor a virtualenv installed into it, nor the PGADMIN_PYTHON_DIR repository variable. macOS only reads the version. It still builds its framework with relocatable-python, because python-build-standalone's relocatable distributions are not framework-shaped and replacing what is shipped there would mean reworking the codesigning and the @loader_path rewriting in _fixup_imports, which is a job of its own. The version itself is unchanged: 3.13.15 is what the released installers already carry, and this makes that existing choice explicit rather than a different one.

# The Python that pgAdmin builds against and ships.

# Every platform's packaging reads this file, so that a given commit produces

# PYTHON_VERSION is the exact CPython release, and is the only value the macOS
|
|
# build needs, since relocatable-python fetches the framework from python.org
|
|
# by version. The Windows build fetches a relocatable distribution from
|
|
# astral-sh/python-build-standalone, whose releases are dated rather than
|
|
# versioned, hence the second value; it then ships the matching embeddable
|
|
# distribution from python.org.
|
|
#
|
|
# The two must be changed together, because the archive names embed both, as
|
|
# cpython-<PYTHON_VERSION>+<PYTHON_BUILD_STANDALONE_TAG>-<platform>.tar.gz, and

# any given tag only carries the CPython releases that were current when it was
