not passed to subprocess.Popen as the default value will be changing in a
future Python to the safer and more often desired value of True.
DeprecationWarnings that show up in a lot of existing code are controversial
and have caused pain in the past. I'd like to leave this on for 3.2 beta1 and
see how things go. We can remove the warning if it is deemed too noisy during
any betas. (case study: the md5 and sha module DeprecationWarnings are loathed
around the world as those modules were never going to be removed in 2.x and
2to3 has a fixer for code that uses them)
* A -b option to start an enhanced browsing session.
* Allow -b and -p options to be used together.
* Specifying port 0 will pick an arbitrary unused socket port.
* A new browse() function to start the new server and browser.
* Show Python version information in the header.
* A *Get* field which takes the same input as the help() function.
* A *Search* field which replaces the Tkinter search box.
* Links to *Module Index*, *Topics*, and *Keywords*.
* Improved source file viewing.
* An HTMLDoc.filelink() method.
* The -g option and the gui() and serve() functions are deprecated.
The motivation for adding this option is that the the functionality it
provides used to be provided by sgmllib in Python2, and was used by,
for example, BeautifulSoup. Without this option, the Python3 version
of BeautifulSoup and the many programs that use it are crippled.
The original patch was by 'kxroberto'. I modified it heavily but kept his
heuristics and test. I also added additional heuristics to fix#975556,
#1046092, and part of #6191. This patch should be completely backward
compatible: the behavior with the default strict=True is unchanged.
Added a few common Popen uses to the tests like we've done for a few other
instances of adding context managers. Eventually the entire test suite
could be converted to use the context manager format.
