Anonymous read-only Git access

Anonymous read-only Git access

[yilu]

Hi,everyone
I want to get the GCC-10 source and I followed the instructions in https://gcc.gnu.org/git.html, however, the command
git clone git://gcc.gnu.org/git/gcc.git SomeLocalDir
cannot work. 
And I found I cannot connect https://gcc.gnu.org/git/gcc.git even without firewall(I'm in China). I got a 403 Forbidden
 "You don't have permission to access /git/gcc.git/ on this server."
 "Apache Server at gcc.gnu.org Port 443".  
What can I do in this situation? 
Thanks.

Do you mean the symptom is hanging?

I'm also in China and did a try just now, then found the speed from 
git://gcc.gnu.org/git/gcc.git is 5.00 ~ 10.00 KiB/s, very slow...
even with single-branch and depth 1, it took me a while to get response.

You probably can try mirror https://mirrors.tuna.tsinghua.edu.cn/git/gcc.git

I guess some guy in BUPT "attacked" gcc.gnu.org somehow (maybe unintentionally,
just playing or testing some software) and caused the entire IP segment to be
banned.

You should contact the administrator of gcc.gnu.org.  In the meantime try

    git clone https://mirrors.tuna.tsinghua.edu.cn/git/gcc.git

It would be very fast since this mirror is in your city :).

(OT: Several BUPT students commenced some unsported behavior in our programming
contests.  So our online judge is also banning BUPT IP segments.)

Good guess.  Maybe try to browse https://gcc.gnu.org/git/.
I was guessing he accessed the link with browser instead of git clone,
since I got the same error too if try with browser.

Oh I misunderstanded the OP.  I thought that message was printed by "git clone"
command...

With a browser it would always show 403.  Technically "406 Not Acceptable" is
better for this case according to RFC 7231, I think.

Thank you both, Kewen.Lin and Xi Ruoyao! I've solved it and actually I didn't use the BUPT network since I'm not at school.

The fact that Git may utilize HTTPS protocol doesn't imply that you can
list its contents with a web browser.


If you have issues cloning GCC's official GCC repo, here is some mitigation:

  # Create an empty repo with a working tree.
  mkdir gcc
  cd gcc
  git init

  # Add mirrors by hand.
  git remote add origin https://gcc.gnu.org/git/gcc.git
  git remote add github https://github.com/gcc-mirror/gcc.git
  git remote add tuna https://mirrors.tuna.tsinghua.edu.cn/git/gcc.git

  # Fetch from reachable mirrors first.
  # TUNA is unlikely to be unreachable from you, however it is
  # slightly left behind other mirrors.
  # This will fetch the bulk of the repo.
  git fetch tuna

  # Fetch more data from another mirror.
  # Objects that have been fetched from TUNA will not be fetched again.
  # There's supposed to be much fewer bytes to download.
  # GitHub is slower, but is less likely to be blocked by Chinese ISPs.
  git fetch github

  # Check out the master branch and initializes the working tree.
  # This is usually a bit behind `origin/master`.
  git checkout -b master github/master


  # Fetch data that have not been mirrored yet.
  # You may postpone this until you have access.
  git fetch origin

  # Set up its tracking branch.
  # You only need to set it once.
  # Note: This requires a successful fetch from `origin`.
  #       If that is not possible for you, please skip this step.
  git branch master --set-upstream-to=origin/master

It works for me, both with authentication and anonymously, and from
machines in the UK and Canada.

What error do you get?

That's expected if you try to connect to that URL using a browser. I'm
not sure whether cloning over HTTPS is expected to work.

You can browse the sources via https://gcc.gnu.org/git/?p=gcc.git instead.

Ah, I didn't see the other messages in the thread. Glad you've solved it.
