Re: Re: drastic memory consumption with a sequence of exceptions

Can you send a complete script which also passes $data that reproduces the problem? Thanks. At 05:27 PM 8/9/2005 +0200, Ron Korving wrote:

The problem occurs in this particular situation: public function process($data) { $largeResultSet = $this->xmlParser->parseString($data); foreach ($largeResultSet as &$item) {

    throw new Exception("error");

} } It only happens if the exception is thrown from within the foreach(). It seems the $largeResultSet is not freed in this case. Using the foreach by reference or not (&$item or $item) does not make a difference. Ron ""Ron Korving"" <r.korving@xit.nl> schreef in bericht news:21.AF.04646.20AC8F24@pb1.pair.com... It is very likely that this has something to do with DOM. It's a huge piece of code though, making it hard to test where the problem really lies.

I've noticed that in a script of mine, memory consumption can explode

quite

drastically when Exceptions are thrown, opposed to very normal memory consumption when exceptions are not thrown. This is the idea: <? class Obj { function process($i) {

    // do a lot of stuff, occupy a lot of memory within the scope of

this

function

    throw new Exception("error");

} } $obj = new Obj(); $errors = array(); for ($i=0; $i < 60; $i++) { try {

    $obj->process();

} catch (Exception $e) {

    $errors[] = $e->getMessage();

} } ?> When exceptions are not thrown, memory consumption is normal. The

method's

local vars are freed and not much more memory is used in the 50th pass compared to the 1st. But when exceptions are thrown, memory consumption increases quite a bit every pass. In the end (within the 60 passes of my loop) over 8 MB's are used. Of course, I can unset a lot of data before throwing exceptions to free

up

memory and the problem will be solved. But it would be nicer if the

cleanup

would happen as an exception is thrown. Can this be considered a bug or is this behavior known and accepted? Ron
