What works for me: git clone --depth=1 https://git.kernel.org/pub/scm/linux/kernel/git/stable cd ./linux git config gc.auto 0 git config pack.threads 1 git fetch --tags as seen in [1]. Q: I do wonder if Git could automatically try to deal with only 1.5 GiB available RAM?Here's an excerpt from my ~/.bashrc, which sets the things up on my Pinebook Pro laptop with an RK3399 SoC and 4 GB of RAM, which is also thermally constrained: # Missing nproc(1) is handled properly REASONABLE_THREADS=$(nproc 2> /dev/null || echo 1) REASONABLE_THREADS=$((${REASONABLE_THREADS} / 2)) ((${REASONABLE_THREADS} == 0)) && REASONABLE_THREADS=1 export GIT_CONFIG_COUNT=3 export GIT_CONFIG_KEY_0='grep.threads' export GIT_CONFIG_VALUE_0=${REASONABLE_THREADS} export GIT_CONFIG_KEY_1='index.threads' export GIT_CONFIG_VALUE_1=${REASONABLE_THREADS} export GIT_CONFIG_KEY_2='pack.threads' export GIT_CONFIG_VALUE_2=${REASONABLE_THREADS} export ZSTD_NBTHREADS=${REASONABLE_THREADS} unset REASONABLE_THREADS Obviously, this does a bit more than configuring git only. Perhaps modifying this to additionally take the amount of RAM into the calculation of REASONABLE_THREADS could be a solution for your use case?
Actually, perhaps we could provide the following files as part of the git project, which would take the above-described approach, and let the distributions package them: - /etc/profile.d/git.sh - /etc/profile.d/git.csh If everyone agrees, I'd we willing to take a crack on these. Of course, all suggestions and thoughts are more than welcome.
