There isn t a great deal of point in storing data types such as photos, videos, and other binary data in a database because they take up a lot of space, which will slow down queries. It is much better to store binary data on the filesystem and store only key properties such as the filename or the creation date in a database. You might be tempted to store your application s data in your project s data directory since it is already present and can be customized in your application s config file. The disadvantage is that because it is already used to store temporary session, cache, and template information, other Pylons developers working on your project might be used to deleting it when they want to clear this temporary information. To avoid this problem, it is better to keep the data directory for cached information and to add a new directory for your user s data. Let s call ours attachments, but the location will be customizable in the config file too.

You could write code like this to load one of the files in this directory: import os from pylons import config def load_file(filename): path = ospathjoin(config['app_conf']['attachments'], filename) fp = open(path, 'rb') data = fpread() fpclose() return data You can save a file to the directory with a function like this: def save_file(filename, data): path = ospathjoin(config['app_conf']['attachments'], filename) fp = open(path, 'wb') fpwrite(data) fpclose() You can list all the files like this: def list_files(): path = ospathjoin(config['app_conf']['attachments']) return os.

because the edge is located between the available pixels. By calculating the amount of color to add to each pixel, a smoother result can be achieved (depending on how close to the edge each pixel is located).

In traditional PKI, the CA publishes a CRL Over time, the length of a CRL grows, and must be downloaded before encrypting or verifying a signature to avoid using a revoked public key In IBE, if we make the public key Bob s e-mail address concatenated with the current date (bob@learnsecuritycom || current-date), then the PKG simply will not provide Bob private keys corresponding to the public keys for those dates after which his key is revoked..

listdir(path) For this example, you ll need to add a new variable in your project config file s [app:main] section: # You could customize this to specify something like /var/lib/myapp/attachments # if you prefer attachments = %(here)s/attachments Each Pylons project has a model directory, which is where code for interacting with the application s data should be stored so you can define the previous functions in model/__init__py, for example You can get information about a particular file like this: path = ospathjoin(config['app_conf']['attachments'], filename) size = ospathgetsize(path) The ospath module documented at http://docspythonorg/lib/module-ospathhtml has other similar methods for accessing other information about files such as getmtime(path), which returns the modification time For additional filesystem information, see the os.

Simply painting the new circle without erasing anything works because Qt always copies the background graphics by default. Because this widget isn t intended to be placed on top of other widgets, that usually means plain gray. You can force Qt to fill the background with the style s background color by setting the autoFillBackground property to true. Listing 7-18. Painting the circle void CircleWidget::paintEvent( QPaintEvent* ) { if( r > 0 ) { QPainter painter( this ); painter.setRenderHint( QPainter::Antialiasing ); painter.setPen( color ); painter.setBrush( color ); painter.drawEllipse( x-r, y-r, 2*r, 2*r ); } } When discussing paint events, there are a few widget attributes that you should be aware of they can be used to further optimize widget painting. You can set these attributes using the setAttribute(Qt::WidgetAttribute, bool) method. The Boolean argument, which

stat() function, which returns an object whose attributes correspond to the members of the stat structure, namely, st_mode (protection bits), st_ino (inode number), st_dev (device), st_nlink (number of hard links), st_uid (user ID of owner), st_gid (group ID of owner), st_size (size of file, in bytes), st_atime (time of most recent access), st_mtime (time of most recent content modification), and st_ctime (platform dependent; time of most recent metadata change on Unix or the time of creation on Windows) It can be used in two ways, as described in the module documentation at http://docspythonorg/lib/os-filedirhtml: >>> import os >>> statinfo = osstat('somefiletxt') >>> statinfo (33188, 422511L, 769L, 1, 1032, 100, 926L, 1105022698,1105022732, 1105022732) >>> statinfost_size 926L >>> statinfo[7] 1105022698.

Recall that for the purposes of preventing XSRF and XSSI attacks, it is not feasible to rely on Referer headers because they are not always present, and at the same time can in certain circumstances be suppressed by a malicious site (see Section 10.3). However, for limiting bandwidth leeching, it is sufficient. It is generally not possible for a page to include an image, script, or style sheet, and suppress the Referer in the resulting request; at the same time, most users browsers will send Referer headers. A third party that relies on our resource would only work for users whose browsers or proxies suppress Referer headers, which makes it impractical for them to do so. And even if a few requests slip through, we are only exposed to a small fraction of the cost we could otherwise expect.
