[libcxx-dev] libcxx git svn incantations

Tue Jan 8 17:12:40 PST 2019

I believe a bunch of the Chromium LLVM developers use the monorepo, so I would expect the script to work on Windows. Adding Zach to confirm.

I've determined that this is a regression between git 2.20.0.windows.1 and 2.20.1.windows.1. I can revert to 2.20.0 and report this upstream.

Hmm, I hope this llvm/utils/git-svn/git-llvm script works on Windows.

I'll wait for the officially official release before attempting to try the monorepo workflow.

Thanks,
STL

I have the same git-svn config and am able to `git svn fetch` successfully, so it might be something specific to your setup.

A potential alternative would be using the monorepo (http://llvm.org/docs/GettingStarted.html#for-developers-to-work-with-a-git-monorepo<https://urldefense.proofpoint.com/v2/url?u=https-3A__nam06.safelinks.protection.outlook.com_-3Furl-3Dhttp-253A-252F-252Fllvm.org-252Fdocs-252FGettingStarted.html-2523for-2Ddevelopers-2Dto-2Dwork-2Dwith-2Da-2Dgit-2Dmonorepo-26data-3D02-257C01-257Cstl-2540exchange.microsoft.com-257C79de701ed73c46ae1c4308d675c7e694-257C72f988bf86f141af91ab2d7cd011db47-257C1-257C0-257C636825898778708868-26sdata-3Dk26BSca33aE508Eb9skcIvk-252BXAaUtldHqKbqO0Z7sQc-253D-26reserved-3D0&d=DwMGaQ&c=5VD0RTtNlTh3ycd41b3MUw&r=o3kDXzdBUE3ljQXKeTWOMw&m=gEFQCcEzZDb4nJOAXiyJOtlDP4qT1Wn6KncwA_vVoEs&s=Ue40-aCd0UAqyFilc7Fsz701oOwRQYeKFoVV6zp9rxo&e=>), although you probably want to use the "official" monorepo at https://github.com/llvm-git-prototype/llvm<https://urldefense.proofpoint.com/v2/url?u=https-3A__nam06.safelinks.protection.outlook.com_-3Furl-3Dhttps-253A-252F-252Fgithub.com-252Fllvm-2Dgit-2Dprototype-252Fllvm-26data-3D02-257C01-257Cstl-2540exchange.microsoft.com-257C79de701ed73c46ae1c4308d675c7e694-257C72f988bf86f141af91ab2d7cd011db47-257C1-257C0-257C636825898778718877-26sdata-3DSo9Ig6OiqyjPA-252FGVPbo0xnNqYb6RvjU5yYTdWOijss4-253D-26reserved-3D0&d=DwMGaQ&c=5VD0RTtNlTh3ycd41b3MUw&r=o3kDXzdBUE3ljQXKeTWOMw&m=gEFQCcEzZDb4nJOAXiyJOtlDP4qT1Wn6KncwA_vVoEs&s=BfWpHfq0JO_cuGF8IBh-7zwWdY96K8McMnuAQvRgmY0&e=> instead (it should be moved over to the LLVM organization on GitHub in a few days, at which point it'll officially be official, but I think the actual repository itself will remain unchanged at this point). The long-term plan is to move all LLVM development to the monorepo, so it might be best to just transition over your workflow right now? It'll still go through svn for committing, but TortoiseSVN has worked well for me on Windows in the past.

C:\Temp\KITTEN\libcxx>git config svn-remote.svn.fetch :refs/remotes/origin/master

C:\Temp\KITTEN\libcxx>git svn rebase -l

At this point, "git svn" hangs. (I see that perl.exe is consuming an entire CPU with nothing else happening.) IIRC, this command is supposed to (slowly) print out a bunch of revision numbers as it works. If I instead run "git svn fetch", it also hangs.

Should I be running different commands? Is a server down or misconfigured? Is "git svn" broken? Is libcxx done with svn and finally using git directly?

Note that I am on Windows Server 2016, running the latest version of 64-bit git, and these incantations worked for me months ago.

C:\Temp>git --version
git version 2.20.1.windows.1
