+ * Secret Labs' Regular Expression Engine
+ *
+ * regular expression matching engine
+ *
+ * partial history:
+ * 1999-10-24 fl created (based on existing template matcher code)
+ * 2000-03-06 fl first alpha, sort of
+ * 2000-08-01 fl fixes for 1.6b1
+ * 2000-08-07 fl use PyOS_CheckStack() if available
+ * 2000-09-20 fl added expand method
+ * 2001-03-20 fl lots of fixes for 2.1b2
+ * 2001-04-15 fl export copyright as Python attribute, not global
+ * 2001-04-28 fl added __copy__ methods (work in progress)
+ * 2001-05-14 fl fixes for 1.5.2 compatibility
+ * 2001-07-01 fl added BIGCHARSET support (from Martin von Loewis)
+ * 2001-10-18 fl fixed group reset issue (from Matthew Mueller)
+ * 2001-10-20 fl added split primitive; reenable unicode for 1.6/2.0/2.1
+ * 2001-10-21 fl added sub/subn primitive
+ * 2001-10-24 fl added finditer primitive (for 2.2 only)
+ * 2001-12-07 fl fixed memory leak in sub/subn (Guido van Rossum)
+ * 2002-11-09 fl fixed empty sub/subn return type
+ * 2003-04-18 mvl fully support 4-byte codes
+ * 2003-10-17 gn implemented non recursive scheme

+/* The macros below should be used to protect recursive SRE_MATCH()

+ * that will backtrack). Explaining:
+ *
+ * - Recursive SRE_MATCH() returned true: that's usually a success
+ * (besides atypical cases like ASSERT_NOT), therefore there's no
+ * reason to restore lastmark;
+ *
+ * - Recursive SRE_MATCH() returned false but the current SRE_MATCH()
+ * is returning to the caller: If the current SRE_MATCH() is the
+ * top function of the recursion, returning false will be a matching
+ * failure, and it doesn't matter where lastmark is pointing to.
+ * If it's *not* the top function, it will be a recursive SRE_MATCH()
+ * failure by itself, and the calling SRE_MATCH() will have to deal
+ * with the failure by the same rules explained here (it will restore
+ * lastmark by itself if necessary);
+ *
+ * - Recursive SRE_MATCH() returned false, and will continue the
+ * outside 'for' loop: must be protected when breaking, since the next
+ * OP could potentially depend on lastmark;
+ *
+ * - Recursive SRE_MATCH() returned false, and will be called again
+ * inside a local for/while loop: must be protected between each
+ * loop iteration, since the recursive SRE_MATCH() could do anything,
+ * and could potentially depend on lastmark.
+ *
+ * For more information, check the discussion at SF patch #712900.

+
+ Two directories must be found, the platform independent directory
+ (prefix), containing the common .py and .pyc files, and the platform
+ dependent directory (exec_prefix), containing the shared library
+ modules. Note that prefix and exec_prefix are the same directory
+ for UEFI installations.
+
+ Separate searches are carried out for prefix and exec_prefix.
+ Each search tries a number of different locations until a ``landmark''
+ file or directory is found. If no prefix or exec_prefix is found, a
+ warning message is issued and the preprocessor defined PREFIX and
+ EXEC_PREFIX are used (even though they may not work); python carries on
+ as best as is possible, but some imports may fail.
+
+ Before any searches are done, the location of the executable is
+ determined. If argv[0] has one or more slashes in it, it is used
+ unchanged. Otherwise, it must have been invoked from the shell's path,
+ so we search %PATH% for the named executable and use that. If the
+ executable was not found on %PATH% (or there was no %PATH% environment
+ variable), the original argv[0] string is used.
+
+ Finally, argv0_path is set to the directory containing the executable
+ (i.e. the last component is stripped).
+
+ With argv0_path in hand, we perform a number of steps. The same steps
+ are performed for prefix and for exec_prefix, but with a different
+ landmark.
+
+ The prefix landmark will always be lib/python.VERSION/os.py and the
+ exec_prefix will always be lib/python.VERSION/dynaload, where VERSION
+ is Python's version number as defined at the beginning of this file.
+
+ First. See if the %PYTHONHOME% environment variable points to the
+ installed location of the Python libraries. If %PYTHONHOME% is set, then
+ it points to prefix and exec_prefix. %PYTHONHOME% can be a single
+ directory, which is used for both, or the prefix and exec_prefix
+ directories separated by the DELIM character.
+
+ Next. Search the directories pointed to by the preprocessor variables
+ PREFIX and EXEC_PREFIX. These paths are prefixed with the volume name
+ extracted from argv0_path. The volume names correspond to the UEFI
+ shell "map" names.
+
+ That's it!
+
+ Well, almost. Once we have determined prefix and exec_prefix, the
+ preprocessor variable PYTHONPATH is used to construct a path. Each
+ relative path on PYTHONPATH is prefixed with prefix. Then the directory
+ containing the shared library modules is appended. The environment
+ variable $PYTHONPATH is inserted in front of it all. Finally, the
+ prefix and exec_prefix globals are tweaked so they reflect the values
+ expected by other code, by stripping the "lib/python$VERSION/..." stuff
+ off. This seems to make more sense given that currently the only
+ known use of sys.prefix and sys.exec_prefix is for the ILU installation
+ process to find the installed Python tree.
+
+ The final, fully resolved, paths should look something like:
+ fs0:/Efi/Tools/python.efi
+ fs0:/Efi/StdLib/lib/python27
+ fs0:/Efi/StdLib/lib/python27/dynaload
