Update to newer mimalloc versions like this: update_mimalloc () { test $# = 1 || { echo "Need a mimalloc version" 1>&2; return 1 }; for oneline in 'mimalloc: adjust for building inside Git' 'Import the source code of mimalloc'; do git revert -n HEAD^{/^"$oneline"} && git checkout HEAD -- Makefile && git commit -sm "Temporarily revert \"$oneline\"" -m 'In preparation for upgrading to a newer mimalloc version.' || return 1; done; for file in $(git show --format='%n' --name-only --diff-filter=A HEAD^{/^"Import the source code of mimalloc "}) compat/mimalloc/arena-abandon.c compat/mimalloc/free.c compat/mimalloc/libc.c compat/mimalloc/prim/prim.c compat/mimalloc/mimalloc-stats.h; do file2=${file#compat/mimalloc/}; case "$file2" in segment-cache.c) : no longer needed; continue ;; bitmap.h | *.c) file2=src/$file2 ;; *.h) file2=include/$file2 ;; esac; mkdir -p "${file%/*}" && git -C /usr/src/mimalloc/ show "$1":$file2 > "$file" && git add "$file" || { echo "Failed: $file2 -> $file" 1>&2; return 1 }; done; conv_sed='sed -n "/^ *eval/d;/ /p"' && git commit -sm "Import the source code of mimalloc $1" -m "Update to newer mimalloc versions like this:" -m "$(set | sed -n '/^update_mimalloc *() *$/,/^}/{s/^./ &/;p}')" -m ' update_mimalloc $MIMALLOC_VERSION' -m 'For convenience, you can set `MIMALLOC_VERSION` and then run:' -m ' eval "$(git show -s <this-commit> | '"$conv_sed"')"' || return 1; git cherry-pick HEAD^{/^'mimalloc: adjust for building inside Git'} || return 1 } update_mimalloc $MIMALLOC_VERSION For convenience, you can set `MIMALLOC_VERSION` and then run: eval "$(git show -s <this-commit> | sed -n "/^ *eval/d;/ /p")" Signed-off-by: Matthias Aßhauer <[email protected]>
We want to compile mimalloc's source code as part of Git, rather than requiring the code to be built as an external library: mimalloc uses a CMake-based build, which is not necessarily easy to integrate into the flavors of Git for Windows (which will be the main benefitting port). Signed-off-by: Johannes Schindelin <[email protected]> Signed-off-by: Matthias Aßhauer <[email protected]>
We also want to keep an eye on mimalloc releases. We're currently on v2.2.4, so we won't need notifications for older release trains. Signed-off-by: Matthias Aßhauer <[email protected]>
