When I open gitk in a particular repository under this version of Git for Windows, I now get a dialog box that says "Error: couldn't execute "git": file name too long". I've noticed that the most pronounced effect is that I cannot see the file diffs (or sometimes the file name list) for any of the commits. I don't know the exact repro, but I've narrowed down the following things: - This does not happen with the same repo if I use a system that has git 2.19.0.windows.1 on another machine. - This does not happen on my current machine in a freshly cloned repo. 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
