The things aren't as bad as I thought there are. Here is an update on this
issue. The key difference to my previous post is: only objects that have
DESTROY method may need to be dealt with. Below is the analysis of the
relevant classes and methods.
* we need to deal with a situation where an object is used to
construct another object, but it's then auto-DESTROYed by perl
rendering the object that used it corrupted.
the solution is to make the newly created objects refer to the
underlying object via magic attachment.
only objects using objects that have DESTROY are effected, so for
example in the case of:
APR::Bucket::eos_create(APR::Bucket::alloc_create(APR::Pool->new)
the object returned by eos_create shouldn't be affected, since
alloc_create()'s object doesn't have perl's DESTROY. so only the
pool object is an issue here (i.e. alloc_create needs special
handling)
relevant objects with DESTROY : Apache::SubRequest,
APR::ThreadMutex, APR::UUID, APR::Pool
=================
=== APR::Pool ===
=================
*** returning objects ***
APR::Brigade:
- mpxs_apr_brigade_create
APR::Bucket:
- apr_bucket_alloc_create
- mpxs_APR__Bucket_setaside
APR::Finfo:
- mpxs_APR__Finfo_stat
APR::IpSubnet:
- mpxs_apr_ipsubnet_create
APR::Pool:
- mpxs_apr_pool_create (not sure about this one)
Apache::RequestUtil:
- mpxs_Apache__RequestRec_new
APR::Table:
- apr_table_copy
- apr_table_overlay
- apr_table_make
APR::ThreadMutex
- mpxs_apr_thread_mutex_create
*** returning strings ***
Apache::ServerUtil
- mpxs_Apache__ServerUtil_server_root_relative (once this is
supported, we no longer need to double copy the string)
Apache::URI:
- ap_construct_server
- ap_construct_url
APR::URI
- mpxs_apr_uri_parse
Apache::Util
- ap_ht_time
- escape_path
==========================
=== Apache::SubRequest ===
==========================
no method uses the object in a way related to the issue in hand
=================
=== APR::UUID ===
=================
no method uses the object in a way related to the issue in hand
========================
=== APR::ThreadMutex ===
========================
no method uses the object in a way related to the issue in hand
