Summary: Scanning through the plain git mapfile is slow. Use the nodemap to speed it up. To avoid unnecessary risks, this only replace the "lookup" feature of the mapfile, other features used by the hggit extension or wire-protocols are unaffected.

Test the gitlookup.useindex=True feature for fast git -> hg commit translation.

Repos:
|
|
- gitrepo: the source git repo
|
|
- hgrepo: sync from the hgrepo
|
|
- hgclient: a dummy repo that talks to hgrepo

Prepare the git repo:
|
|
|
|
$ . "$TESTDIR/hggit/testutil"
|
|
|
|
$ git init --quiet gitrepo
|
|
$ cd gitrepo
|

$ git checkout --quiet -b beta

$ echo beta > beta
|

$ git add beta
|
|
$ fn_git_commit -m 'add beta'
|

$ cd $TESTTMP

$ hg clone gitrepo hgrepo

2 files updated, 0 files merged, 0 files removed, 0 files unresolved

The gitlookup interface is exposed at the wireproto layer. Use another repo to test it:
|
|
|
|
$ newrepo hgclient
|

$ hg pull -r _gitlookup_git_7eeab2ea75ec1ac0ff3d500b5b6f8a3447dd7c03 $TESTTMP/hgrepo

Test the debugbuildgitnodemap command. This runs the build explicitly instead of on-demand:
|
|
|
|
$ cd $TESTTMP/hgrepo
|

|
0 new commits are indexed
|

$ rm -rf .hg/git-nodemap .hg/git-nodemap-lastrev

$ hg debugbuildgitnodemap
