Hi I have a problem getting the svn log in a branch after sync-merging a commit from trunk. This commit in trunk is a merge of an old and complex branch with many commits.
The client accessing the repository over svn:// url. (paths and text is redacted) The head revision is: 10801 When I run the following command on the client (in the working copy), it prints a long partial xml-log output, then hangs. /usr/bin/svn log --xml -g -v -r 10701:HEAD /path/to/branch-wc When observing in "top", the command uses no visible CPU resources on hang. (I waited ca. 2 minutes) The hanging command does mot exits on CTRL-c, it does not exits on "kill -TERM pid", I have to send "kill -KILL pid" to terminate it. When I run the command with strace it hangs at read(4, ...SNIP... read(4, " ( ) ( 4:file true false ) ) ( 1"..., 16384) = 16384 mmap(NULL, 8192, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7f63f1d83000 mmap(NULL, 8192, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7f63f1d81000 mmap(NULL, 8192, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7f63f1d7f000 mmap(NULL, 8192, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7f63f1d7d000 mmap(NULL, 8192, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7f63f1d7b000 mmap(NULL, 8192, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7f63f1d79000 read(4, "***/****-***_redacted_*****_****"..., 16384) = 14773 mmap(NULL, 8192, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7f63f1d77000 mmap(NULL, 8192, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7f63f1d75000 mmap(NULL, 8192, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7f63f1d73000 mmap(NULL, 8192, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7f63f1d71000 mmap(NULL, 8192, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7f63f1d6f000 mmap(NULL, 8192, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7f63f1d6d000 read(4, When I observe the server, there is a CPU activity at the begin, but when the client hangs, the server seems to be in idle. Just a corresponding svnserve process is there with no visible cpu usage. In svnserve.log is nothing relevant to see. The svnserve command is: svnserve -d -r /path/to/repositories \ --log-file=/var/log/svnserve.log \ --memory-cache-size 1024 \ --cache-txdeltas yes \ --cache-fulltexts yes When I try to get the xml-log on the server with the corresponding file:// repository URL: /usr/bin/svn log --xml -g -v -r 10701:HEAD file://path/to/local/repositories/project/branch The command finishes in ca 5-10 seconds and I get the xml output, but the output has a way too many </logentry> lines. There are 1217 occurrences of the string “<logentry" and 33191 occurrences of the string "</logentry>" in the output xml. There are several thousand lines of </logentry> in a row in many places in repeated blocks.
