Fastest database solution
I'm writing a small application for detecting source code plagiarism that currently relies on a database to store lines of code. The application has two primary functions: adding a new file to the database and comparing a file to those that are already stored in the database. I started out using sqlite3, but was not satisfied with the performance results. I then tried using psycopg2 with a local postgresql server, and the performance got even worse. My simple benchmarks show that sqlite3 is an average of 3.5 times faster at inserting a file, and on average less than a tenth of a second slower than psycopg2 at matching a file. I expected postgresql to be a lot faster ... is there some peculiarity in psycopg2 that could be causing slowdown? Are these performance results typical? Any suggestions on what to try from here? I don't think my code/queries are inherently slow, but I'm not a DBA or a very accomplished Python developer, so I could be wrong. Any advice is appreciated. -- http://mail.python.org/mailman/listinfo/python-list

Currently, I am stripping extra whitespace and end-of-line characters from each line of source code and storing that in addition to its hash in a table. That table is used for exact-match comparisons. I am also passing the source code through flex/bison to canonicalize identifiers -- the resulting lines are also hashed and stored in a table. That table is used for structural matching. Both tables are queried to find matching hashes. I'm not sure how I could make the hash lookups faster... On my small test dataset, this solution has detected all of the plagiarism with high confidence. It's also beneficial to me to use this Python application as I can easily integrate it with other Python scripts I use to prepare code for review. > > Roger > -BEGIN PGP SIGNATURE- > Version: GnuPG v1.4.9 (GNU/Linux) > > iEYEARECAAYFAkmL/wgACgkQmOOfHg372QTAmACg0INMfUKA10Uc6UJwNhYhDeoV > EKwAoKpDMRzr7GzCKeYxn93TU69nDx4X > =4r01 > -END PGP SIGNATURE- > > -- > http://mail.python.org/mailman/listinfo/python-list -- http://mail.python.org/mailman/listinfo/python-list

However, what is of particular importance is that the matching itself be fast. While the original lines of code are stored in the database, I am performing matching based on only hashes. Would storing the original code in the same table as the hash cause significant slowdown if I am querying by hash only? I think I may try this approach anyways, just to make retrieving the original source code after finding a match faster, but I am still primarily concerned with the speed of the hash lookups. > -- > Marc-Andre Lemburg > eGenix.com > > Professional Python Services directly from the Source (#1, Feb 06 2009) >>>> Python/Zope Consulting and Support ...http://www.egenix.com/ >>>> mxODBC.Zope.Database.Adapter ... http://zope.egenix.com/ >>>> mxODBC, mxDateTime, mxTextTools ...http://python.egenix.com/ > > > ::: Try our new mxODBC.Connect Python Database Interface for free ! > > > eGenix.com Software, Skills and Services GmbH Pastor-Loeh-Str.48 >D-40764 Langenfeld, Germany.

Take a look at the specification here: http://www.microsoft.com/downloads/details.aspx?familyid=dd422b8d-ff06-4207-b476-6b5396a18a2b&displaylang=en You will find that images are specified by one or more RTF control words followed by a long string of hex data. For this special purpose, you will not need to write a parser for the entire specification. Just search the file for the correct sequence of control words, extract the hex data that follows, and save it to a file. It helps if you open the RTF document in a text editor and locate the specific control group that contains the image, as the format and order of control words varies depending on the application that created it. If all of your documents are created with the same application, it will be much easier. -- http://mail.python.org/mailman/listinfo/python-list

You just need to change your User-Agent so that Google doesn't know a
Python script is making the request:
import urllib2
headers = {'User-Agent' : 'Mozilla/5.0 (X11; U; Linux i686; en-US;
rv:1.9.0.6) Gecko/2009020911 Ubuntu/8.04 (hardy) Firefox/3.0.6'}
query = 'foo'
req = urllib2.Request('http://www.google.com/search?&q=' + query,
headers=headers)
response = urllib2.urlopen(req)
results = response.read()

You could do something like this:
f = open('file.txt', 'r')
for line in f:
a,b = line.split()[1:-1] # tokenize the string into sequence of
length 4 and store two middle values in a and b
if a != b:
print line
f.close()
