Potential memory leak

[vanderhoorn]

As you may know, while strings are garbage collected, symbols are not.

In the build_elements on line 27 all element names are symbolized (name.to_sym). So if you use the savon gem intensively in an application and you use a lot of different element names, the memory usage of the application will increase substantially over time. I don't think using symbols in this case is a wise approach.

your probably right. using symbols internally might not be necessary‎ and i have to look into that.

Hi, @rubiii , @vanderhoorn

This does cause memory leaks in our program, we have a program which will read a huge data from a webservice, when it run a day after it reached 8G memory footprint.

[rubiii]

we can't change the symbols for version 2, but i'll make sure that version 3 doesn't cause such problems.

[vanderhoorn]

No problem.

Added a task for this in the version 3 TODO list #473
