On some Debian/unstable machine with some Subversion working copy,
"svn up" is sometimes freezing. A "strace -p ..." shows that both
the client and the server are waiting on a "read": "read(6," for
the client, "read(0," for the server.
On the client, after almost half an hour, I eventually got the
error:
client_loop: send disconnect: Broken pipe
svn: E210002: Network connection closed unexpectedly
and several dozens of seconds later, the svnserve was killed by
a SIGPIPE (according to strace).
Earlier, it took 17 minutes for "svn up" to complete (instead of
less that one second usually up to a few seconds), without any
error, but the corresponding svnserve was still running for a few
more minutes.
The last one took:
0.34s user 0.09s system 0% cpu 19:32.19 total
Again, after a few minutes, the svnserve is still running, but
there's still the sshd:
root │ └─> 16718 sshd: svn [priv]
svn │ └─> 16725 sshd: svn@notty
svn │ └─> 16766 sh -c svnserve -t -r d_joooj/home/svn/root
--tunnel-user=vinc17/cventin
svn │ └─> 16767 svnserve -t -r d_joooj/home/svn/root
--tunnel-user=vinc17/cventin
I haven't noticed any network issue: interactive ssh works fine.
Checking out a new working copy from the same machine was fine
too. But later, a "svn up" on this working copy was freezing
too... well, it took 3:49. But in general, this seems fine from
this second copy, while problems are much more common from the
first one.
Client:
svn, version 1.10.4 (r1850624)
compiled Jan 23 2019, 03:41:34 on x86_64-pc-linux-gnu
Server:
svnserve, version 1.9.5 (r1770682)
compiled Jul 30 2019, 02:45:42 on x86_64-pc-linux-gnu
journalctl does not show any issue (except the usual message
"DIGEST-MD5 common mech free" for the svn client).
With another Debian/unstable machine as the client, which is
in the same room as the other one (thus similar conditions),
I haven't noticed any issue.
Any idea?
