Summary: XQ: leftovers after deleting document
Initial Comment:
Using todays stable build (preJune, May28, 2008) but it happens with earlier
builds as well), the dbfarm isn't cleaned up as expected after deleting a
document with 'pf:del-doc()'.
When repeatedly adding and deleting documents, the leftovers start piling up,
and eventually the system runs out of disk-space.
See example below.
bash-3.2$ wc -c /tmp/aap.xml
292890833 /tmp/aap.xml
bash-3.2$ echo 'pf:add-doc("/tmp/aap.xml","aap.xml")' | mclient -lxq
bash-3.2$ du -sh /tmp/dbfolder/
367M /tmp/dbfolder/
bash-3.2$ echo 'pf:add-doc("/tmp/aap.xml","aap_1.xml")' | mclient -lxq
bash-3.2$ du -sh /tmp/dbfolder/
733M /tmp/dbfolder/
bash-3.2$ echo 'pf:add-doc("/tmp/aap.xml","aap_2.xml")' | mclient -lxq
bash-3.2$ du -sh /tmp/dbfolder/
1.1G /tmp/dbfolder/
bash-3.2$
bash-3.2$ echo 'pf:del-doc("aap_2.xml")' | mclient -lxq
bash-3.2$ du -sh /tmp/dbfolder/
997M /tmp/dbfolder/
bash-3.2$ echo 'pf:del-doc("aap_1.xml")' | mclient -lxq
bash-3.2$ du -sh /tmp/dbfolder/
895M /tmp/dbfolder/
bash-3.2$ du -sh /tmp/dbfolder/
895M /tmp/dbfolder/
bash-3.2$ du -sh /tmp/dbfolder/
895M /tmp/dbfolder/
bash-3.2$ echo 'pf:del-doc("aap.xml")' | mclient -lxq
bash-3.2$ du -sh /tmp/dbfolder/
794M /tmp/dbfolder/
bash-3.2$ du -sh /tmp/dbfolder/
794M /tmp/dbfolder/
bash-3.2$
