Package: distcc
Version: 3.1-5
Severity: minor
Summary:
The message
Warning: failed to distribute and fallbacks are disabled
should be an error, not a warning.
One of the hosts in our build cluster is broken:
osstest@army:~$ DISTCC_HOSTS=armpit/4 distcc gcc -Wall -c t.c
distcc[6366] (dcc_readx) ERROR: failed to read: Connection reset by peer
distcc[6366] (dcc_r_token_int) ERROR: read failed while waiting for token "DONE"
distcc[6366] (dcc_r_result_header) ERROR: server provided no answer. Is the
server configured to allow access from your IP address? Does the server have
the compiler installed? Is the server configured to access the compiler?
distcc[6366] Warning: failed to distribute t.c to armpit/4, running locally
instead
osstest@army:~$ DISTCC_HOSTS=armpit/4 distcc gcc -Wall -c t.c
distcc[6372] (dcc_build_somewhere) Warning: failed to distribute, running
locally instead
osstest@army:~$ DISTCC_FALLBACK=0 DISTCC_HOSTS=armpit/4 distcc gcc -Wall -c t.c
distcc[6399] (dcc_build_somewhere) Warning: failed to distribute and fallbacks
are disabled
osstest@army:~$
There are some problems with these error messages. This bug report is
about the message from the third run above. It appears from strace
that the 2nd and 3rd runs didn't run on armpit because of a backoff
algorithm built into distcc:
mkdir("/local/scratch/osstest/.distcc", 0777) = -1 EEXIST (File exists)
mkdir("/local/scratch/osstest/.distcc/lock", 0777) = -1 EEXIST (File exists)
stat64("/local/scratch/osstest/.distcc/lock/backoff_tcp_armpit_3632_0",
{st_mode=S_IFREG|0644, st_size=1, ...}) = 0
gettimeofday({1407754354, 166974}, NULL) = 0
write(2, "distcc[6430] (dcc_build_somewher"..., 92) = 92
The 3rd run's output does not contain an error message, despite the
overall operation having failed completely. I think that particular
message ought to be an error.
Ian.
