David Fraser commented on MODPYTHON-223:
----------------------------------------
As a side comment that may be relevant, I've had print statements running under
mod_python in Apache on Windows failing because the LOCALE is set to the C
locale and so encoding things can cause issues...
> Make sys.stdout/sys.stderr log properly to Apache error logs.

> Key: MODPYTHON-223
> URL: https://issues.apache.org/jira/browse/MODPYTHON-223
> Project: mod_python
> Issue Type: New Feature
> Components: core
> Affects Versions: 3.3.1
> Reporter: Graham Dumpleton
>
> When sys.stderr or sys.stdout are written to directly, or when the 'print'
> statement is used without a target file object, any text output will make it
> into the Apache error log files, but it will only get there after a flush has
> been performed on stdout/stderr. Most of the time the streams will only be
> flushed when Apache is being shutdown with the result being that the output
> is far removed in the log file from any other messages that may have been
> logged at the same time using the normal Apache error logging functions.
> Further, anything output via stdout/stderr does not have associated with it
> the error log prefix giving the time the output was generated.
> All this can be improved by replacing sys.stderr and sys.stdout with custom
> Python objects which buffer any output and flushing it through to the Apache
> error log using the proper ap_log_error() function after each newline is
> encountered. This will mean that output appears straight away as soon as
> newline sent and output will be prefixed with date/time string.
> Do note though that the output cannot be associated with a specific virtual
> host and thus would go to the main Apache error log file even if each virtual
> host has its own log file. This is the same as now though when sys.stderr and
> sys.stdout are used.
