System Symlinks

# Python 3.12 (System)
python -> python3.12
python3 -> python3.12
python3.12 (binary)

# Python 3.14t (Custom)
python3.14t (binary, no python/python3 symlink)
                    

🛡️ Python 3.14t does NOT overwrite system symlinks python and python3, preventing accidental system breakage.

sys.path Locations

Python 3.12:

/data/data/com.termux/files/usr/lib/python3.12/site-packages

Python 3.14t:

~/.local/lib/python3.14t/site-packages
~/python314t-6/termux-python314t-3.14.0/lib/python3.14t/site-packages
                        

Isolation Test Results

Test	Result	Status
httpx (3.14t) visible to 3.12?	NO - Completely isolated	✅ PASS
requests (3.12) visible to 3.14t?	NO - Completely isolated	✅ PASS
Same package (chardet) in both?	YES - No conflicts	✅ PASS

🎯 Conclusion: Packages are COMPLETELY ISOLATED between Python versions.

🔄 Compatibility with uv

Interpreter Detection

$ uv python list
✓ cpython-3.12.12-linux-aarch64-none    /data/data/com.termux/files/usr/bin/python3.12
✓ cpython-3.12.12-linux-aarch64-none    /data/data/com.termux/files/usr/bin/python3
✓ cpython-3.12.12-linux-aarch64-none    /data/data/com.termux/files/usr/bin/python
                    

Observation: uv only sees Python 3.12. Python 3.14t is NOT automatically detected.

Virtual Environment Creation

Python 3.12 + uv:

$ uv venv --python python3.12 test-312
✅ Works correctly
                        

Python 3.14t + uv:

$ uv venv --python ~/.local/bin/python3.14t test-314t
❌ ERROR: Unknown operating system: android
                        

⚠️ uv DOES NOT SUPPORT Python 3.14t on Android. Use python3.14t -m pip directly.

Package Installation

With Python 3.12 (via uv):

$ uv pip install --python python3.12 requests
✅ Installed successfully
                        

With Python 3.14t (direct pip):

$ python3.14t -m pip install httpx
✅ Works correctly (without uv)
                        

📦 Installation Safety Analysis

What install.sh Does

✅ Forces installation to ~/.local instead of system /usr
✅ Copies Python 3.14t binary and libraries to user space
✅ Installs OpenSSL libraries for SSL/HTTPS support
✅ Creates compatibility symlink: libpython3.14.so → libpython3.14t.so
✅ Does NOT overwrite system files python, python3, or python3.12

🛡️ Safety: Installation does NOT modify any Termux system files.

🧪 Coexistence Tests

Concurrent Execution

$ python3.12 --version
Python 3.12.12

$ python3.14t --version
Python 3.14.0
                        

✅ Both work simultaneously

Independent pip

$ python3.12 -m pip --version
pip 25.3 (python 3.12)

$ python3.14t -m pip --version
pip 25.3 (python 3.14)
                        

✅ Fully independent

🔧 Issues & Solutions

Issue	Impact	Solution
uv doesn't support 3.14t	Medium	Use `python3.14t -m pip` directly
ensurepip fails in venv	Low	Use `--without-pip` flag and install manually

💡 Recommended Workflows

🏢 For Production Projects (with uv):

uv venv --python python3.12
source .venv/bin/activate
uv pip install <packages>
                    

🧪 For Python 3.14t Experiments (free-threading GIL):

python3.14t -m venv --without-pip venv
source venv/bin/activate
python -m ensurepip --upgrade
pip install <packages>
                    

⚡ For Quick Tests (no venv):

python3.14t -m pip install --user <package>
python3.14t my_script.py
                    

❓ Key Questions Answered

Does 3.14t interfere with uv?

❌ NO

uv doesn't detect Python 3.14t and works normally with Python 3.12.

Does 3.14t interfere with Python 3.12?

❌ NO

Packages are completely isolated, PATH is properly configured.

Is the installation safe?

✅ YES

Doesn't modify system files, installs to ~/.local.

Can both versions coexist?
