Some storage backends, notably filesystem provider using either
Mac OS X or NFS, do not support extended attributes and cannot store
the ETag. References andrewgaul/s3proxy#135.
Previously this called String.replaceFirst which uses a regular
expression and incorrectly handles characters like *. Also remove
other correct but unnecessary call to String.replaceFirst.
Use parseLong instead of parseInt when parsing open-ended byte ranges in LocalBlobStore. Without this fix, any "from byte x" or "to byte x" getBlob() call will throw a NumberFormatException if x is too big to fit into an int (2 GB).

These folders represent directories in the filesystem blobstore which
real blobstores do not have. Their presence complicates providing the
correct marker for paginated listing. Future commits will remove
folders entirely.
Swift implements multi-part upload with user-visible parts and an
explicit manifest. When deleting an MPU blob it can delete only the
manifest or both the manifest and parts. For consistency with other
providers, we now do the latter in the portable abstraction. Swift
ignores the multipart-manifest=delete parameter for single-part
objects. Fixesandrewgaul/s3proxy#92.
jclouds should not check if the string is encoded, but rather expect
that all strings would be encoded prior to transmission. As part of
that change, we must make sure that no code relies on such behavior
within jclouds. This commit adds a blobstore test to check encoding
pattern for blobs. It also removes the encoding check in the Strings2
class and the related test.
Changed the LocalBlobStore to use FOLDER, as opposed to RELATIVE_PATH
when creating directories. Changed the delete keys strategy to treat
FOLDER blobs as regular blobs.
Azure does not allow arbitrary marker specification and the generic
testListContainerMarker test should not assume that the behavior is
possible. There is already a separate test for such scenario that is
skipped on Azure.
Propagates the changes to add delimiter support to the local blob
store. The prefix option no longer works with the non-recursive
option. The caller _must_ set the delimiter option to enable the same
functionality.
Move the prefix and delimiter tests from BaseContainerLiveTest to
BaseContainerIntegrationTest, as that class is subclassed in
Filesystem integration tests. This will make sure the file system blob
store will not regress.
The ListContainerTest is updated to _not_ use a file separator
character, as that leads to a possible creation of directories.
Instead, "-" is used as the delimiter for the delimiter option tests.
Adds the delimiter support in the local blob store. The existing
directory implementation is preserved and is not compatible with the
delimiter option, as the existing implementation assumes the usage of
filesystem directories.
The patch adds delimiter option support in the generic blob store
interface. A live integration test is added to verify that jclouds
correctly lists objects separated by a delimiter.
When the delimiter option is specified, local blob store should behave
similarly to swift and return the directory marker blobs (directory
blobs) and the common prefix. This undoes the filtering we were
previously doing.
When listing blobs, Swift returns an array of "subdir" entries for
every common prefix. The openstack-swift provider needs to process
such entries and add them to the result set. The subdir array is an
array of strings, so additional metadata needs to be added to the
objects (bogus ETag, bogus LastModifiedDate, and so on).
When directory marker blobs are used, this means that potential _two_
entries are generated for every directory if:
1. the delimiter is set and matches the directory blob (e.g. dir/ and
delimiter /)
2. there are objects under the directory name (e.g. dir/blob), which
will result in results that include common prefixes (subdir)
In the above example, we should expect two results: "dir" and "dir/"
representing the directory marker blob and the common prefix,
respectively.
This is caught in the testDirectory integration test.
The patch changes the behavior of the Swift provider to correctly
handle the results in the subdir stanza and changes the test to expect
the directory marker to be returned in the list.
When filtering results, we have to consider that a result was added to
the common prefixes list in its entirety (i.e. a directory). Such
results should be filtered out from the delimiter test.
An example that demonstrates this problem is if one creates a
directory "foo" and an object within it called "file". When listing
the results, they will include the directory object "foo" and the
object under "foo/file". During a non-recursive listing, we create a
list of common prefixes ("foo"). Subsequently, jclouds should remove
all objects that include the delimiter ("/"), however, that would not
apply to "foo". With the change to include the delimiter in the
listing, we need to be careful not to return two values "foo" and
"foo/".
A unit test for the local blob store to highlight this problem is
included. An integration test "testDirectory" also catches this issue.
Relaxes the membership check in prefix testing. The check is no longer
sensitive to ordering of the results, as different providers may
append, prepend, or insert in sorted order the relative prefixes.
We should not append a "/" to the marker when returning list results
in the case of directories (RELATIVE_PATH), as the names will already
include the delimiter.
Added a jclouds test to catch such regressions in the local store in
the future.
Implements prefix support for the local blob store. The patch allows
for correctly parsing prefixes that may not terminate with a delimiter
(i.e. foo with delimiter "/" and a key foobar/key, should return
foobar/ as the common path) and ones that do (i.e. foo/).
NOTE: there is a small change in behavior in this patch.
LocalBlobStore used to return the common prefixes without the
delimiter character ("/"). However, other providers do include the
delimiter (I checked S3 and Google Cloud Storage) and LocalBlobStore
should include it as well.
jclouds should issue the requests to create all of the containers in
the container pool before sleeping. The patch modifies the
createContainerAndEnsureEmpty() method to take an additional
parameter, which specifies whether awaitConsistency() should be called
or not.

code can fail. there isn't really a way to use uri for transient
blobstore anyway, and removing it is the easier option. for
