3.APR_BRIGADE_FOREACH无效了
修改文件:mod_cserv.cpp
将APR_BRIGADE_FOREACH用
for (e = APR_BRIGADE_FIRST(b);
e != APR_BRIGADE_SENTINEL(b);
e = APR_BUCKET_NEXT(e))
替代。找到源码的change log,是这么说的:
/**
- * Iterate through a bucket brigade
- * @param e The current bucket
- * @param b The brigade to iterate over
- * @remark This is the same as either:
- *
- * e = APR_BRIGADE_FIRST(b);
- * while (e != APR_BRIGADE_SENTINEL(b)) {
- * ...
- * e = APR_BUCKET_NEXT(e);
- * }
- * OR
- * for (e = APR_BRIGADE_FIRST(b);
- * e != APR_BRIGADE_SENTINEL(b);
- * e = APR_BUCKET_NEXT(e)) {
- * ...
- * }
- *
- * @warning Be aware that you cannot change the value of e within
- * the foreach loop, nor can you destroy the bucket it points to.
- * Modifying the prev and next pointers of the bucket is dangerous
- * but can be done if you're careful. If you change e's value or
- * destroy the bucket it points to, then APR_BRIGADE_FOREACH
- * will have no way to find out what bucket to use for its next
- * iteration. The reason for this can be seen by looking closely
- * at the equivalent loops given in the tip above. So, for example,
- * if you are writing a loop that empties out a brigade one bucket
- * at a time, APR_BRIGADE_FOREACH just won't work for you. Do it
- * by hand, like so:
- *
- * while (!APR_BRIGADE_EMPTY(b)) {
- * e = APR_BRIGADE_FIRST(b);
- * ...
- * apr_bucket_delete(e);
- * }
- *
- * @deprecated This macro causes more headaches than it's worth. Use
- * one of the alternatives documented here instead; the clarity gained
- * in what's really going on is well worth the extra line or two of code.
- * This macro will be removed at some point in the future.
