Build latest mintpy and push to custom OpenSARlab conda channel

Sometimes the latest version of MintPy is desired within a notebook but the official release is not current. These instructions will show how to build MintPy and push to a custom conda channel.

This assumes that the user has an Anaconda.org account and that this account is attached to a opensarlab conda channel. Instructions on how to do this are not provided here.

A. Create working directory

mkdir conda-mintpy
cd conda-mintpy

B. Create conda environment

conda create -n conda-build python=3.10 anaconda-client
conda activate conda-build

C. Clone conda feedstock of mintpy. https://github.com/conda-forge/mintpy-feedstock

git clone git@github.com:conda-forge/mintpy-feedstock.git

D. Clone mintpy code repo. https://github.com/insarlab/mintpy. Only the latest commit is included to speed up download. Drop the --depth 1 to get the whole history.

git clone --depth 1 git@github.com:insarlab/MintPy.git

E. Assuming mintpy main is used and is also the latest, we won't make any changes to mintpy

The feedstock is a framework for building. It does not have the source code to build within it. Copy Mintpy source to feedstock recipes.

cp -r MintPy mintpy-feedstock/recipe/MintPy

F. Make versioning clear and build MintPy from local. The VERSION here is a working example. The actual version is subject to change.

VERSION=1.3.3.dev.COMMIT_SHORT_HASH

G. Edit mintpy-feedstock/recipe/meta.yaml

-{% set version = "1.3.2" %}
+{% set version = 1.3.3.dev.COMMIT_SHORT_HASH %}

source:
-    url: https://github.com/insarlab/{{ name }}/archive/refs/tags/v{{ version }}.tar.gz
-    sha256: 6c1242dee74f13b96aa4b1f8d50c45ec486397796e4bd4bf3f67849f921bfe7f
+    path: MintPy

H. Build This may take a while.

cd mintpy-feedstock
python3.10 build-locally.py
cd ..

I. After a successful build, check for artifacts in mintpy-feedstock/build_artifacts/

J. Push changes to OpenSARlab conda channel.

# Login to individual account where you are an owner of OpenSARlab org
anaconda login

# Upload artifacts
anaconda upload --user opensarlab mintpy-feedstock/build_artifacts/noarch/mintpy-*.tar.bz2

K. Download and check version

mamba install -c opensarlab -c conda-forge mintpy=VERSION
conda list | grep -i mintpy

L. Cleanup as desired

cd ../
ls

rm -rf conda-mintpy

conda deactivate
conda env remove -n conda-build
conda env list
