IBM Z Software
This portal is to open public enhancement requests against IBM Z Software products. To view all of your ideas submitted to IBM, create and manage groups of Ideas, or create an idea explicitly set to be either visible by all (public) or visible only to you and IBM (private), use the IBM Unified Ideas Portal (https://ideas.ibm.com).
Shape the future of IBM!
We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:
Search existing ideas
Start by searching and reviewing ideas and requests to enhance a product or service. Take a look at ideas others have posted, and add a comment, vote, or subscribe to updates on them if they matter to you. If you can't find what you are looking for,
Post your ideas
Post an idea.
Get feedback from the IBM team and other customers to refine your idea.
Follow the idea through the IBM Ideas process.

Due to processing by IBM, this request was reassigned to have the following updated attributes:
Brand - Servers and Systems Software
Product family - z Systems Software
Product - z/TPF
For recording keeping, the previous attributes were:
Brand - WebSphere
Product family - Transaction Processing
Product - z/TPF
This is delivered with PJ42733 on z/TPF PUT12.
Two updates are identified:
1)eh_globals.cc updates to eliminate COW on soinit functionality.
2)string.h TPF-specific functionality for strchr:
__BEGIN_NAMESPACE_STD
#if defined _TPF_SOURCE && !defined __SYSC__
/* Find the first occurrence of C in S. */
extern inline char *strchr (__const char *__s, int __c) __THROW {
return (char *)memchr((void *)__s, __c, __builtin_strlen(__s) + 1);
}
... results in two stsr assembler instructions being created; one to find the end of the string S, the other to find the character C in question. This ends up being inefficient for xml files that tend to average 250K bytes but can easily be 1 million or more bytes long. The recommendation here is to remove this TPF only modification and similar str* functions that call corresponding mem* functions with a strlen() as the last parm: strcpy, strncpy, strcat, strncat.
