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(tlogfiletlogfptopentIOErrortnologtlogtdolog(tallargs((s/usr/lib64/python2.7/cgi.pytinitlogGs   cGstj||ddS(s=Write a log message to the log file.

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. iNsw+b(ttempfilet TemporaryFile(RetbinaryR((s/usr/lib64/python2.7/cgi.pyRs Ni (RhRiRjR-tosR7RfRgRRRRRRRRRRRRyRRzR{RRRRRRRR(((s/usr/lib64/python2.7/cgi.pyR`s6) s              cBs#eZdZejdddZRS(sxForm content as dictionary with a list of values per field. form = FormContentDict() form[key] -> [value, value, ...] key in form -> Boolean form.keys() -> [key, key, ...] form.values() -> [[val, val, ...], [val, val, ...], ...] form.items() -> [(key, [val, val, ...]), (key, [val, val, ...]), ...] form.dict == {key: [val, val, ...], ...} icCs6td|d|d||_|_|d|_dS(NR7R8R9R+(R tdictRNt query_string(ReR7R8R9((s/usr/lib64/python2.7/cgi.pyRfs (RhRiRjRR7Rf(((s/usr/lib64/python2.7/cgi.pyRs cBs2eZdZdZdZdZdZRS(sForm content as dictionary expecting a single value per field.
