From: Luke Shumaker <lukeshu@parabola.nu> Without --stream, `hg clone` reencodes+recompresses the entire repository, to the storage settings of the host. But download_hg() already did that on the initial network clone, and it is 100% pointless duplicated work for the local clone. The work that this saves is CPU-bound (not disk-bound), and is restricted to a single core. The --stream flag has only existed since Mercurial 4.4 (2017-11-01). Prior to that, it was named --uncompressed. --uncompressed still exists as a compatibility alias for --stream, and marked deprecated, though there is currently no schedule for its removal. --- scripts/libmakepkg/source/hg.sh.in | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/scripts/libmakepkg/source/hg.sh.in b/scripts/libmakepkg/source/hg.sh.in index ae9aed3b..7346e1e3 100644 --- a/scripts/libmakepkg/source/hg.sh.in +++ b/scripts/libmakepkg/source/hg.sh.in @@ -94,7 +94,7 @@ extract_hg() { plain "$(gettext "Aborting...")" exit 1 fi - elif ! hg clone -u "$ref" "$dir" "${dir##*/}"; then + elif ! hg clone -u "$ref" --stream "$dir" "${dir##*/}"; then error "$(gettext "Failure while creating working copy of %s %s repo")" "${repo}" "hg" plain "$(gettext "Aborting...")" exit 1 -- 2.18.0
