Even though this function is called initlog(), you should always use log(); log is a variable that is set either to initlog (initially), to dolog (once the log file has been opened), or to nolog (when logging is disabled). The first argument is a format string; the remaining arguments (if any) are arguments to the % operator, so e.g. log("%s: %s", "a", "b") will write "a: b" to the log file, followed by a newline. If the global logfp is not None, it should be a file object to which log data is written. If the global logfp is None, the global logfile may be a string giving a filename to open, in append mode. This file should be world writable!!! If the file can't be opened, logging is silently disabled (since there is no safe place where we could send an error message). taN(tlogfiletlogfptopentIOErrortnologtlogtdologtallargs(R((t /data/zmath/lib/python2.4/cgi.pytinitlog:s  cGsti||dƒdS(s=Write a log message to the log file.

This class provides naming, typing, files stored on disk, and more. At the top level, it is accessible like a dictionary, whose keys are the field names. (Note: None can occur as a field name.) The items are either a Python list (if there's multiple values) or another FieldStorage or MiniFieldStorage object. If it's a single object, it has the following attributes: name: the field name, if specified; otherwise None filename: the filename, if specified; otherwise None; this is the client side filename, *not* the file name on which it is stored (that's a temporary file you don't deal with) value: the value as a *string*; for file uploads, this transparently reads the file every time you request the value file: the file(-like) object from which you can read the data; None if the data is stored a simple string type: the content-type, or None if not specified type_options: dictionary of options specified on the content-type line disposition: content-disposition, or None if not specified disposition_options: dictionary of corresponding options headers: a dictionary(-like) object (sometimes rfc822.Message or a subclass thereof) containing *all* headers The class is subclassable, mostly for the purpose of overriding the make_file() method, which is called internally to come up with a file open for reading and writing. This makes it possible to override the default choice of storing all files in a temporary directory and unlinking them as soon as they have been opened.

The file will be used as follows: - data is written to it - seek(0) - data is read from it The 'binary' argument is unused -- the file is always opened in binary mode. This version opens a temporary file for reading and writing, and immediately deletes (unlinks) it. The trick (on Unix!) is that the file can still be used, but it can't be opened by another process, and it will automatically be deleted when it is closed or when the current process terminates. If you want a more permanent file, you derive a class which overrides this method. If you want a visible temporary file that is nevertheless automatically deleted when the script terminates, try defining a __del__ method in a derived class which unlinks the temporary files you have created.
