[svn] Steel FilenameChecker against race conditions.
Since FilenameChecker was just using os.path.exists() to see whether or not
a filename was free, it had a time of check vs. time of use vulnerability.
Matthew was prodding me about the inconsistency with DirectoryChecker, so
that inspired me to fix this. This also entailed some refactoring. Thanks
Matthew.
dtrx Installation Documentation =============================== Requirements ------------ dtrx will work out of the box with Python_ 2.4 or greater. You can also use Python 2.3 if you separately install the `subprocess module`_. .. _Python: http://www.python.org/ .. _`subprocess module`: http://www.lysator.liu.se/~astrand/popen5/ dtrx calls out to different external tools to support different archive types. Most of these are already installed on most GNU/Linux systems, so you probably won't have to worry about these too much, but just for completeness, the exact requirements for each format are as follows: tar archives tar zip archives unzip, zipinfo cpio archives cpio rpm archives rpm2cpio, cpio deb archives ar, tar, zcat gem archives tar, zcat 7z archives 7z Microsoft Cabinet archives cabextract Files compressed with gzip or compress zcat Files compressed with bzip2 bzcat Files compressed with lzma lzcat Installation ------------ dtrx is just a simple script, making it easy to stash wherever you need it. Just copy ``scripts/dtrx`` to a location that's convenient for you. If you'd like to install the program system-wide, you can run the following as root or equivalent:: python setup.py install --prefix=/usr/local Running Tests ------------- dtrx comes with a suite of tests that are designed to ensure it's running properly. If you'd like, you can run these tests on your own system. Simply run the following command from the dtrx source directory:: python tests/compare.py To run the tests, you'll need the `syck module`_. .. _syck module: http://whytheluckystiff.net/syck/ If everything's in order, all the tests should pass. Note that some of them will fail if some of the programs listed above aren't installed on your system. Many of the tests will fail if for some reason you're missing the very common commands, like tar and zcat.
