From: Junio C Hamano Date: Fri, 19 Oct 2018 04:34:08 +0000 (+0900) Subject: Merge branch 'tb/filter-alternate-refs' X-Git-Tag: v2.20.0-rc0~149 X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/465e73fff380808f0ba3fb17984ab8636afb6405?ds=inline;hp=-c Merge branch 'tb/filter-alternate-refs' When pushing into a repository that borrows its objects from an alternate object store, "git receive-pack" that responds to the push request on the other side lists the tips of refs in the alternate to reduce the amount of objects transferred. This sometimes is detrimental when the number of refs in the alternate is absurdly large, in which case the bandwidth saved in potentially fewer objects transferred is wasted in excessively large ref advertisement. The alternate refs that are advertised are now configurable with a pair of configuration variables. * tb/filter-alternate-refs: transport.c: introduce core.alternateRefsPrefixes transport.c: introduce core.alternateRefsCommand transport.c: extract 'fill_alternate_refs_command' transport: drop refnames from for_each_alternate_ref --- 465e73fff380808f0ba3fb17984ab8636afb6405 diff --combined Documentation/config.txt index 0ae4d7077b,3486f9f749..552827935a --- a/Documentation/config.txt +++ b/Documentation/config.txt @@@ -225,7 -225,7 +225,7 @@@ boolean: false;; Boolean false literals are `no`, `off`, `false`, `0` and the empty string. + -When converting value to the canonical form using `--bool` type +When converting a value to its canonical form using the `--type=bool` type specifier, 'git config' will ensure that the output is "true" or "false" (spelled in lowercase). @@@ -616,6 -616,24 +616,24 @@@ core.preferSymlinkRefs: This is sometimes needed to work with old scripts that expect HEAD to be a symbolic link. + core.alternateRefsCommand:: + When advertising tips of available history from an alternate, use the shell to + execute the specified command instead of linkgit:git-for-each-ref[1].
