# git version 2.20.1.windows.1 throws file name too long in gitk 10 messages from 2019-01-04 to 2019-05-29. Participants: Bret Barkelew, Johannes Schindelin. Thread: https://gitlist.dev/t/50150 ## Bret Barkelew, 2019-01-04 02:21 Subject: git version 2.20.1.windows.1 throws file name too long in gitk Message-ID: URL: https://gitlist.dev/e/CAGTkKag2sFy%2BOf%3D6uQeiGOQm0-NBrh9ixgzDoQXKR73%2BCt3raQ%40mail.gmail.com ``` 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 ``` ## Bret Barkelew, 2019-01-04 03:38 Subject: Re: git version 2.20.1.windows.1 throws file name too long in gitk Message-ID: URL: https://gitlist.dev/e/CAGTkKag-fTy3iZAKJxEnWD6_b_3pfuYvQQKBkLaeSL8wKM2sfg%40mail.gmail.com In-Reply-To: ``` They are the exact same path (with a different drive letter). Another thing I've been able to confirm is I uninstalled git 2.20.1 and installed 2.19.0 on the failing system, and the older version of Git works. I've also tried a suggested fix I saw elsewhere to enable long path names in the Windows registry, which did not resolve the issue with git 2.20.1. Happy to collect any additional data. - Bret On Thu, Jan 3, 2019 at 7:10 PM Bryan Turner wrote: > > On Thu, Jan 3, 2019 at 6:21 PM Bret Barkelew wrote: >> >> 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".

Thank you for reaching out with detailed information internally, I am happy to report that together with the help of Max Kirillov, this is now resolved and a snapshot is available from https://wingit.blob.core.windows.net/files/index.html that has the fix.

Thank you very much for helping! It might be late, but it is even more welcome! Thanks for the feedback (and I am particularly happy that it works for you). Ciao, Johannes P.S.: For lurkers, I just realized that I never linked to the patches: https://github.com/git-for-windows/git/pull/2170 As this PR really only touches code that is already in Git for Windows, but not yet in git.git, I think I'll try to find some time post-v2.22.0 to brush up those gitk patches and contribute them to the Git mailing list for review. > On Sat, Apr 27, 2019 at 4:20 PM Johannes Schindelin > wrote: > > > > Hi Bret, > > > > On Thu, 18 Apr 2019, Bret Barkelew wrote: > > > > > This issue is now being reported by more users inside MS.
