[llvm-dev] How can I obtain a commit of LLVM using a svn revision number?

[Alexandre Ganea via llvm-dev]

Hello Zhide,

You can use LLVM Phabricator for that purpose.

For example, if you're looking for svn commit 258109, add 'rL' in front of it, such as: https://reviews.llvm.org/rL258109
Since the entire svn history was replayed on github, you can then search for the following on the same website: "llvm-svn: 258109"

This will give you the correspondent github commit hash for the svn commit above:
https://reviews.llvm.org/rG31955002975b5ae9e4130d0fbeb954bbeb0f95f0

Would that suit what you're trying to achieve?

Alex.

Objet : [llvm-dev] How can I obtain a commit of LLVM using a svn revision number?

Hi, developers,
For some reasons, I want to obtain some old commits of LLVM. However, I only know the svn revision numbers of these commits of LLVM.
I tried the command "svn co https://llvm.org/svn/llvm-project/llvm/trunk llvm" listed in "Getting Started with the LLVM System", but the server seems to be not working.
I always get the following message.
"svn: E000104: Error running context: Connection reset by peer"

I also try the commands listed in "Moving LLVM Projects to GitHub",
"
git clone https://llvm.org/git/llvm.git
cd llvm/
git svn init https://llvm.org/svn/llvm-project/llvm/trunk --username=<username>
git config svn-remote.svn.fetch :refs/remotes/origin/master
git svn rebase -l
git checkout `git svn find-rev -B r258109`
cd tools
git clone https://llvm.org/git/clang.git
cd clang/
git svn init https://llvm.org/svn/llvm-project/clang/trunk --username=<username>
git config svn-remote.svn.fetch :refs/remotes/origin/master
git svn rebase -l
git checkout `git svn find-rev -B r258109`
"
but it is still not working. When I execute the command "git svn rebase -l" for clang, I get the following message.
"Unable to determine upstream SVN information from working tree history"

So is there any way to obtain special commit of LLVM using a svn revision number?

Best,
Zhide
