Summary: hang in rsync (match.c)
Product: rsync
Version: 3.0.9
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: P5
Component: core
AssignedTo: way...@samba.org
ReportedBy: jer...@jeremysanders.net
QAContact: rsync...@samba.org
I think I'm hitting a hang in rsync. I'm using rev
c0d07c098724ee8c382a498cab991f7d8467d778 in the b3.0.x branch.
The command is:
rsync -raHx --stats --inplace --no-whole-file --delete
/xback2_back1/home_rcr36/20110707-000502/ /mnt/btrfs/home_rcr36/current/
Where both file systems are local. Running strace on the process shows no
activity. The hanging process is the rsync with the lowest PID.
I attached gdb to the hanging rsync. Here is the back trace:
0x000000000041e5c4 in hash_search (f=4, s=0xcc1ec0, buf=0xcc1ef0,
len=2000967340) at match.c:211
211 if (updating_basis_file && s->sums[i].offset <
offset
(gdb) back
#0 0x000000000041e5c4 in hash_search (f=4, s=0xcc1ec0, buf=0xcc1ef0,

#4 0x000000000041d455 in start_client (argc=2, argv=0xcac240) at main.c:1287
#5 main (argc=2, argv=0xcac240) at main.c:1514
The system is Fedora Linux 14 x86-64. I continued the program and reattached
the debugger. It was stuck in the same place.
