This issue is now being reported by more users inside MS. I'll also reach out to the Git for Windows advocacy group to see if they have any ideas. I have not had time to figure out the inner workings of Tcl/Tk. Is there any way to turn on tracing/logging in Git for which commands are being called by gitk?

That length is calculated including the path to the repository itself and then to the file inside the repository. That means, for example, a given repository cloned to C:\repo may not have issues, but the same repository cloned to C:\Users\Bryan\Documents\workspaces\repo may. > > > > > > > > > > > >> > > > > > >> However, as soon as the remote updates with any changes on a given > > > > > >> fetch/pull, the repo is put in a bad state permanently. > > > > > >> > > > > > >> I've pasted the output from gitk below... > > > > > >> > > > > > >> couldn't execute "git": file name too long > > > > > >> couldn't execute "git": file name too long > > > > > >> while executing > > > > > >> "open $cmd r" > > > > > >> (procedure "getallcommits" line 48) > > > > > >> invoked from within > > > > > >> "getallcommits" > > > > > >> (procedure "readcache" line 80) > > > > > >> invoked from within > > > > > >> "readcache file827e200" > > > > > >> ("eval" body line 1) > > > > > >> invoked from within > > > > > >> "eval $script" > > > > > >> (procedure "dorunq" line 11) > > > > > >> invoked from within > > > > > >> "dorunq" > > > > > >> ("after" script) > > > > > >> > > > > > >> Happy to gather whatever data needed. > > > > > >> Thanks! > > > > > >> - Bret Barkelew > > > > > > > >
