Hi,

All my 4 testers (I have 4 machines running several Mingw targets) are 
always failing pulling new versions from GitHub. This problem started 
some days ago. I've tried to reset all machines, network equipment, 
disabling antivirus, firewall, modified http attributes, modified the 
regression script to use git protocol instead of https, etc. with no luck.

I'm using Windows machines with official Git. Any clue on what's going 
on? Maybe Github recently does not like so many submodules?

Example of failure (several libraries can fail during "git pull 
"--recurse-submodules""):

-------------------
-------------------
-------------------

Fetching submodule libs/io
fatal: unable to access 'https://github.com/boostorg/io.git/': OpenSSL 
SSL_read: SSL_ERROR_SYSCALL, errno 10054

Then:

# git_source_checkout failed with message "GIT command "git pull 
"--recurse-submodules"" failed with code 1"
# Retrying (5 more attempts).
# Executing GIT command: c:\boost\develop\boost_root> git submodule 
foreach "git submodule deinit ."

-------------------
-------------------

All retries fail and the script fails with error:

-------------------
-------------------
-------------------

# git_source_checkout failed with message "GIT command "git pull 
"--recurse-submodules"" failed with code 1"
# Giving up.
Traceback (most recent call last):

      self.main()

      self.retry(self.git_source_checkout)
    File "c:\boost\develop\boost_regression_src\regression.py", line

      return f()
    File "c:\boost\develop\boost_regression_src\regression.py", line 
875, in git_source_checkout
      self.git_checkout(git_info['boost'], self.git_branch(), clean)
    File "c:\boost\develop\boost_regression_src\regression.py", line 
849, in git_checkout
      self.git_command( 'pull', '--recurse-submodules' )
    File "c:\boost\develop\boost_regression_src\regression.py", line 
834, in git_command
      raise Exception( 'GIT command "%s" failed with code %d' % 
(git_cli, rc) )
Exception: GIT command "git pull "--recurse-submodules"" failed with code 1

Errors are never in the same libraries, very few times the checkout 
succeeds and a regression is run. Anyone else having these problems?

I've attached the log of one failure in case someone can see any clue. I 
really don't see how to solve this, so I won't be able to run regressions.

Best,

Ion
