PersistentPerl release 2.21 is available at:
http://daemoninc.com/PersistentPerl/download.html
The changes since 2.20 are:
- Fix too many backends problem reported by Theo Petersen. The
problem is due to temp-file corruption that occurs when the
web-server sends a TERM signal to the frontend while it is working
on the temp file. It also results in some backends failing due
to the corruption. Added a fix so that signals are always blocked
while working on the temp file.
- Shutdown handler should be called after script is touched.
- Fixes for Mac OS X 10.1. Workaround the sigpending() bug,
and add msync() which appears to fix a shared-memory flushing
problem when temp-file is expanded.
