require 'xml/libxml'
(1..10000).each{|time|
XML::Document.file('test.xml')
p time if time % 100 == 0
}
It won't segfault anymore, but now I get the following error:
Too many open filesI/O warning : failed to load external entity
"test.xml"
libxml-test.rb:7:in `file': test.xml (IOError)
from libxml-test.rb:7
from libxml-test.rb:6:in `each'
from libxml-test.rb:6
However, the error disappears if "GC.start" is inserted just above
XML::Document.file(...).
Right. This is another Ruby GC issue. If you don't call GC.start,
then all the documents that you have created remain open. I assume
this causes the OS to eventually run out of file handles, thus
resulting in the error (which is being raised by libxml not Ruby).
By calling GC.start, the documents are freed and the file handles
are released.
So I don't see this as a bug in the libxml bindings.
Hrm.... while it's not technically a libxml error, one could easily
argue that libxml should call rb_gc_start() if the open fails and
retry. I just committed a fix to trunk that fixes this scenario. It
will still spew errors whenever the GC is called due to the lack of
wrapping around libxml's error handling, but it's appropriate to leave
that there for the time being. -sc
