The prop[osal is to have a script called 'git' which would call hg to return the Git hash of a repository cloned with hg. Then Emacs will get what it wants what it calls "git rev-parse". > Mercurial can without problems translate between both hashes. > > However suppose I run the compiled version for a while (and suppose I > even have deleted the cloned mercurial repository) and want to > report a bug, then I don't know for which mercurial I compiled that > version, and I cannot calculate the corresponding git hash. AFAIR, the hash is computed when Emacs is built, and is recorded in the built Emacs. It cannot be calculated after the build.
