File operations always raise a ENOENT error when a file doesn't exist.
Checking the file exists before the operation adds a race condition
condition where the file could be removed between operations. As the
operation already raises an error on a missing file, avoid this race and
avoid checking the file exists twice. Instead only check a file exists
by catching the ENOENT error.
Leading slashes in the second urljoin argument will return exactly that
argument, breaking FileSystemStorage.url behavior if called with a
parameter with leading slashes.
Also added test cases for null bytes and None. Thanks to Markus for
help and review.
New Storage.get_{accessed,created,modified}_time() methods convert the
naive time from now-deprecated {accessed,created_modified}_time()
methods into aware objects in UTC if USE_TZ=True.
This reverts commit f36151ed16.
Adding kwargs to deconstructed objects does not achieve useful
forward-compatibility in general, since additional arguments are silently
dropped rather than having their intended effect. In fact, it can make the
failure more difficult to diagnose. Thanks Shai Berger for discussion.
Added a test for the condition safe_join is designed to prevent.
Previously, a generic ValueError was raised. It was impossible to tell
an intentional exception raised to implement safe_join's contract from
an unintentional exception caused by incorrect inputs or unexpected
conditions. That resulted in bizarre exception catching patterns, which
this patch removes.
Since safe_join is a private API and since the change is unlikely to
create security issues for users who use it anyway -- at worst, an
uncaught SuspiciousFileOperation exception will bubble up -- it isn't
documented.
This patch is two-fold; first it ensure that Django does close everything in
request.FILES at the end of the request and secondly the storage system should
no longer close any files during save, it's up to the caller to handle that --
or let Django close the files at the end of the request.
Previously when collecting static files, the directories would receive permissions
from the global umask. Now the default permission comes from FILE_UPLOAD_DIRECTORY_PERMISSIONS
and there's an option to specify the permissions by subclassing any of the
static files storage classes and setting the directory_permissions_mode parameter.
Previously, when collecting static files, the files would receive permission
from FILE_UPLOAD_PERMISSIONS. Now, there's an option to give different
permission from uploaded files permission by subclassing any of the static
files storage classes and setting the file_permissions_mode parameter.
Thanks dblack at atlassian.com for the suggestion.
SuspiciousOperations have been differentiated into subclasses, and
are now logged to a 'django.security.*' logger. SuspiciousOperations
that reach django.core.handlers.base.BaseHandler will now return a 400
instead of a 500.
Thanks to tiwoc for the report, and Carl Meyer and Donald Stufft
for review.
* Renamed smart_unicode to smart_text (but kept the old name under
Python 2 for backwards compatibility).
* Renamed smart_str to smart_bytes.
* Re-introduced smart_str as an alias for smart_text under Python 3
and smart_bytes under Python 2 (which is backwards compatible).
Thus smart_str always returns a str objects.
* Used the new smart_str in a few places where both Python 2 and 3
want a str.
Instead of just continually appending "_" to duplicate file names, Django's
default storage now appends `_1`, `_2`, `_3`, etc.
Thanks to ianschenck and Thilo.

LazyObject called a public method ``get_all_members`` on wrapped objects in
order to allow introspection. This could easily cause name clashes with
existing methods on wrapped objects, and so has been changed to use the
standard methods. This could be slightly backwards-incompatible, in obscure
cases, if the undocumented LazyObject has been used externally.
