Merge lp:~barry/ubuntu/natty/python-launchpadlib/bug-702375 into lp:ubuntu/natty/python-launchpadlib

[Barry Warsaw]

Update to upstream 1.9.5 as requested by Leonard Richardson.

[Didier Roche-Tolomelli (didrocks)]

the change looks good, in any case, you have a better knowledge than I on the subject :)

I just wondered as you get a lot of API break in that upgrade if you tested it through the archives? Maybe as well blog about it before the upload so that people having scripts which will be broken scripts or tools (I'm pretty sure Quickly will break reading the changelog ;)) can take some advanced tests toward it.

As it seems the (long) discussion on bug #686690 found an agreement, if the first case is done, people can sponsor it.

[Barry Warsaw (barry)]

Actually, I think Leonard has the definitive word on API issues, so I'll request a comment from him.

[Francis J. Lacoste (flacoste)]

My understanding was that all changes were backward compatible. You only get the new behavior when you change the API.

[Francis J. Lacoste (flacoste)]

According to Benji, the only backward incompatible change is the removal of the edge root. We could add it back but make it only pointing at production.

But at the same time, this is alpha release, so it's probably a good idea to have any apps pointing at edge be upgraded. Make it a good time to take advantage of the new desktop login possibility.

[Leonard Richardson (leonardr)]

I plan to contact the developers of launchpadlib apps that are in Ubuntu and help them make the upgrade.

This branch contains all the changes I expected.

review: Approve

[Leonard Richardson (leonardr)]

BTW, today launchpadlib stopped working with edge. I have a branch to make existing code work (by giving a deprecation warning to people who use edge, and having them use production instead). It would be great to get this into Natty:
https://code.launchpad.net/~leonardr/launchpadlib/fake-edge/+merge/49651

It would also be great to get my backport of this feature into Maverick:
https://code.launchpad.net/~leonardr/launchpadlib/edge-fakery-for-maverick/+merge/49653

[Barry Warsaw (barry)]

I changed this to a work-in-progress and will obsolete the branch. Instead, I'm going to work through Luca to get 1.9.6 into Debian unstable and then we'll sync it over to Natty.

For backporting to Maverick, we'll have to do an SRU.

https://wiki.ubuntu.com/StableReleaseUpdates

Leonard, if you can do the bookkeeping work on proposing the SRU, I'll prepare a package branch.

         NEWS for launchpadlib
         =====================
         
+        1.9.5 (2010-02-08)
+        ==================
+        
+        - Fixed a bug that prevented the deprecated get_token_and_login code
+          from working, and that required that users of get_token_and_login
+          get a new token on every usage.
+        
+        1.9.4 (2010-01-18)
+        ==================
+        
+        - Removed references to the 'edge' service root, which is being phased out.
+        
+        - Fixed a minor bug in the upload_release_tarball contrib script which
+          was causing tarballs to be uploaded with the wrong media type.
+        
+        - The XSLT stylesheet for converting the Launchpad WADL into HTML
+          documentation has been moved back into Launchpad.
+        
+        1.9.3 (2011-01-10)
+        ==================
+        
+        - The keyring package import is now delayed until the keyring needs to be
+          accessed.  This reduces launchapdlib users' exposure to unintended side
+          effects of importing keyring (KWallet authorization dialogs and the
+          registration of a SIGCHLD handler).
+        
+        1.9.2 (2011-01-07)
+        ==================
+        
+        - Added a missing import.
+        
+        1.9.1 (2011-01-06)
+        ==================
+        
+        - Corrected a test failure.
+        
+        1.9.0 (2011-01-05)
+        ==================
+        
+        - When an authorization token expires or becomes invalid, attempt to
+          acquire a new one, even in the middle of a session, rather than
+          crashing.
+        
+        - The HTML generated by wadl-to-refhtml.xsl now validates.
+        
+        - Most of the helper login methods have been deprecated. There are now
+          only two helper methods:
+        
+          * Launchpad.login_anonymously, for anonymous credential-free access.
+          * Launchpad.login_with, for programs that need a credential.
+        
+        
+        1.8.0 (2010-11-15)
+        ==================
+        
+        - Store authorization tokens in the Gnome keyring or KDE wallet, when
+          available. The credentials_file parameter of Launchpad.login_with() is now
+          ignored.
+        
+        - By default, Launchpad.login_with() now asks Launchpad for
+          desktop-wide integration. This removes the need for each individual
+          application to get its own OAuth token.
+        
+        1.7.0 (2010-09-23)
+        ==================
+        
+        - Removed "fake Launchpad browser" code that didn't work and was
+          misleading developers.
+        
+        - Added support for http://qastaging.launchpad.net by adding
+          astaging to the uris.
+        
+        1.6.5 (2010-08-23)
+        ==================
+        
+        - Make launchpadlib compatible with the latest lazr.restfulclient.
+        
+        1.6.4 (2010-08-18)
+        ==================
+        
+        - Test fixes.
+        
+        1.6.3 (2010-08-12)
+        ==================
+        
+        - Instead of making the end-user hit Enter after authorizing an
+          application to access their Launchpad account, launchpadlib will
+          automatically poll Launchpad until the user makes a decision.
+        
+        - launchpadlib now raises a more helpful exception when the end-user
+          explicitly denies access to a launchpadlib application.
+        
+        - Improved the XSLT stylesheet to reflect Launchpad's more complex
+          top-level structure. [bug=286941]

+Credential storage
+==================

+After authorizing an application to access Launchpad on a user's behalf,

+        1.6.2 (2010-06-21)

+        
+        - Extended the optimization from version 1.6.1 to apply to Launchpad's
+          top-level collection of people.
+        
+        1.6.1 (2010-06-16)
+        ==================
+        
+        - Added an optimization that lets launchpadlib avoid making an HTTP

+        
+        1.6.0 (2010-04-07)
+        ==================
+        
+        - Fixed a test to work against the latest version of Launchpad.
+        
+        1.5.8 (2010-03-25)
+        ==================
+        
+        - Use version 1.0 of the Launchpad web service by default.
+        
+        1.5.7 (2010-03-16)
+        ==================
+        
+        - Send a Referer header whenever making requests to the Launchpad
+          website (as opposed to the web service) to avoid falling afoul of
+          new cross-site-request-forgery countermeasures.
+        
+        1.5.6 (2010-03-04)
+        ==================
+        
+        - Fixed a minor bug when using login_with() to access a version of the
+          Launchpad web service other than the default.
+        
+        - Added a check to catch old client code that would cause newer
+          versions of launchpadlib to make nonsensical requests to
+          https://api.launchpad.dev/beta/beta/, and raise a helpful exception
+          telling the developer how to fix it.
+        
+        1.5.5
+        =====
+        
+        - Added the ability to access different versions of the Launchpad web
+          service.
+        
+        1.5.4 (2009-12-17)
+        ==================
+        
+        - Made it easy to get anonymous access to a Launchpad instance.
+        
+        - Made it easy to plug in different clients that take the user's
+          Launchpad login and password for purposes of authorizing a request
+          token. The most secure technique is still the default: to open the
+          user's web browser to the appropriate Launchpad page.
+        
+        - Introduced a command-line script bin/launchpad-credentials-console,
+          which takes the user's Launchpad login and password, and authorizes
+          a request token on their behalf.
+        
+        - Introduced a command-line script bin/launchpad-request-token, which
+          creates a request token on any Launchpad installation and dumps the
+          JSON description of that token to standard output.
+        
+        - Shorthand service names like 'edge' should now be respected
+          everywhere in launchpadlib.
+        
+        1.5.3 (2009-10-22)
+        ==================
+        
+        - Moved some more code from launchpadlib into the more generic
+          lazr.restfulclient.
+        
+        1.5.2 (2009-10-01)
+        ==================
+        
+        - Added a number of new sample scripts from elsewhere.
+        
+        - Added a reference to the production Launchpad instance.
+        
+        - Made it easier to specify a Launchpad instance to run against.
+        
+        1.5.1 (2009-07-16)
+        ==================
+        
+        - Added a sample script for uploading a release tarball to Launchpad.
+        
+        1.5.0 (2009-07-09)
+        ==================
+        
+        - Most of launchpadlib's code has been moved to the generic
+          lazr.restfulclient library. launchpadlib now contains only code
+          specific to Launchpad. There should be no changes in functionality.
+        
+        - Moved bootstrap.py into the top-level directory. Having it in a
+          subdirectory with a top-level symlink was breaking installation on
+          Windows.
+        
+        - The notice to the end-user (that we're opening their web
+          browser) is now better formatted.
+        
+        1.0.1 (2009-05-30)
+        ==================
+        
+        - Correct tests for new launchpad cache behavior in librarian
+        
+        - Remove build dependency on setuptools_bzr because it was causing bzr to be
+          downloaded during installation of the package, which was unnecessary and
+          annoying.
+        
+        1.0 (2009-03-24)
+        ================
+        
+        - Initial release on PyPI

 NEWS for launchpadlib
 =====================
 
+1.9.5 (2010-02-08)
+==================
+
+- Fixed a bug that prevented the deprecated get_token_and_login code
+  from working, and that required that users of get_token_and_login
+  get a new token on every usage.
+
+1.9.4 (2010-01-18)
+==================
+
+- Removed references to the 'edge' service root, which is being phased out.
+
+- Fixed a minor bug in the upload_release_tarball contrib script which
+  was causing tarballs to be uploaded with the wrong media type.
+
+- The XSLT stylesheet for converting the Launchpad WADL into HTML
+  documentation has been moved back into Launchpad.
+
+1.9.3 (2011-01-10)
+==================
+
+- The keyring package import is now delayed until the keyring needs to be
+  accessed.  This reduces launchapdlib users' exposure to unintended side
+  effects of importing keyring (KWallet authorization dialogs and the
+  registration of a SIGCHLD handler).
+
+1.9.2 (2011-01-07)
+==================
+
+- Added a missing import.
+
+1.9.1 (2011-01-06)
+==================
+
+- Corrected a test failure.
+
+1.9.0 (2011-01-05)
+==================
+
+- When an authorization token expires or becomes invalid, attempt to
+  acquire a new one, even in the middle of a session, rather than
+  crashing.
+
+- The HTML generated by wadl-to-refhtml.xsl now validates.
+
+- Most of the helper login methods have been deprecated. There are now
+  only two helper methods:
+
+  * Launchpad.login_anonymously, for anonymous credential-free access.
+  * Launchpad.login_with, for programs that need a credential.
+
+
+1.8.0 (2010-11-15)
+==================
+
+- Store authorization tokens in the Gnome keyring or KDE wallet, when
+  available. The credentials_file parameter of Launchpad.login_with() is now
+  ignored.
+
+- By default, Launchpad.login_with() now asks Launchpad for
+  desktop-wide integration. This removes the need for each individual
+  application to get its own OAuth token.
+
+1.7.0 (2010-09-23)
+==================
+
+- Removed "fake Launchpad browser" code that didn't work and was
+  misleading developers.
+
+- Added support for http://qastaging.launchpad.net by adding
+  astaging to the uris.
+
+1.6.5 (2010-08-23)
+==================
+
+- Make launchpadlib compatible with the latest lazr.restfulclient.
+
+1.6.4 (2010-08-18)
+==================
+
+- Test fixes.
+
+1.6.3 (2010-08-12)
+==================
+
+- Instead of making the end-user hit Enter after authorizing an
+  application to access their Launchpad account, launchpadlib will
+  automatically poll Launchpad until the user makes a decision.
+
+- launchpadlib now raises a more helpful exception when the end-user
+  explicitly denies access to a launchpadlib application.
+
+- Improved the XSLT stylesheet to reflect Launchpad's more complex
+  top-level structure. [bug=286941]
+
+- Test fixes. [bug=488448,616055]
+
 1.6.2 (2010-06-21)

-*******************************
-The simulated Launchpad browser
-*******************************
-
-The SimulatedLaunchpadBrowser class is a scriptable browser-like class
-that can be trusted with the end-user's username and password. It
-fulfils the same function as the user's web browser, but because it's
-scriptable can be used to create non-browser trusted clients.
-
-    >>> username = '[e-mail]'
-    >>> password = 'zeca'
-    >>> web_root = 'http://launchpad.dev:8085/'
-
-Before showing how SimulatedLaunchpadBrowser can authorize a request
-token, let's create a request token to authorize.
-
-    >>> from launchpadlib.credentials import Credentials
-    >>> credentials = Credentials("doctest consumer")
-    >>> context="firefox"
-    >>> validate_url = credentials.get_request_token(
-    ...     web_root=web_root, context=context)
-    >>> request_token = credentials._request_token.key
-
-get_token_info()
-================
-
-If you have the end-user's username and password, you can use
-get_token_info() to get information about one of the user's request
-tokens. It's useful for confirming that the end-user gave the correct
-username and password, and for reconciling the list of access levels a
-client will accept with Launchpad's master list.
-
-    >>> from launchpadlib.credentials import SimulatedLaunchpadBrowser
-    >>> from launchpadlib.testing.helpers import TestableLaunchpad
-
-    >>> browser = SimulatedLaunchpadBrowser(web_root)
-
-If you make an unauthorized request, you'll get a 401 error.
-(Launchpad returns 200, but SimulatedLaunchpadBrowser sniffs it and
-changes it to a 401.)
-
-    >>> response, content = browser.get_token_info(
-    ...     "baduser", "badpasword", request_token)
-    >>> print response.status
-    401
-
-If you provide the right authorization, you'll get back information
-about your request token.
-
-    >>> response, content = browser.get_token_info(
-    ...     username, password, request_token)
-    >>> print response['content-type']
-    application/json
-
-    # XXX leonardr 2009-10-28 bug=462773 These two URLs should be
-    # exactly the same, but the Content-Location is missing the
-    # lp.context.
-    >>> validate_url.startswith(response['content-location'])
-    True
-
-    >>> import simplejson
-    >>> json = simplejson.loads(content)
-    >>> json['oauth_token'] == request_token
-    True
-
-    >>> print json['oauth_token_consumer']
-    doctest consumer
-
-You'll also get information about the available access
-levels.
-
-    >>> print sorted([level['value'] for level in json['access_levels']])
-    ['READ_PRIVATE', ... 'UNAUTHORIZED', ...]
-
-If you provide a list of possible access levels, you'll
-get back a list that reconciles the list you gave with
-Launchpad's access levels.
-
-    >>> response, content = browser.get_token_info(
-    ...     username, password, request_token,
-    ...     ["READ_PUBLIC", "READ_PRIVATE", "NO_SUCH_ACCESS_LEVEL"])
-
-    >>> print response['content-type']
-    application/json
-
-    >>> json = simplejson.loads(content)
-    >>> print sorted(
-    ...     [level['value'] for level in json['access_levels']])
-    ['READ_PRIVATE', 'READ_PUBLIC', 'UNAUTHORIZED']
-
-Note that the nonexistent access level has been removed from the
-reconciled list, and the "Unauthorized" access level (which must
-always be an option) has been added.
-
-grant_access()
-==============
-
-If you have the end-user's username and password, you can use
-grant_access() to authorize a request token.
-
-If you make an unauthorized request, you'll get a 401 error.  (As with
-get_token_info(), Launchpad returns 200, but SimulatedLaunchpadBrowser
-sniffs it and changes it to a 401.)
-
-    >>> access_level = "READ_PRIVATE"
-
-    >>> response, content = browser.grant_access(
-    ...     "baduser", "badpasword", request_token, access_level, context)
-    >>> print response.status
-    401
-
-If you try to grant an invalid level of access, you'll get a
-400 error.
-
-    >>> response, content = browser.grant_access(
-    ...     username, password, request_token,
-    ...     "NO_SUCH_ACCESS_LEVEL")
-    >>> print response.status
-    400
-
-If you provide all the necessary information, you'll get a 200
-response code and the request token will be authorized.
-
-    >>> response, content = browser.grant_access(
-    ...     username, password, request_token, access_level)
-    >>> print response.status
-    200
-
-If you try to grant access to a request token that's already
-been authorized, you'll get a 409 error.
-
-    >>> response, content = browser.grant_access(
-    ...     username, password, request_token, access_level)
-    >>> print response.status
-    409
-
-Now that the request token is authorized, we can exchange it for an
-access token.
-
-    >>> credentials.exchange_request_token_for_access_token(
-    ...     web_root=web_root)
-    >>> credentials.access_token.key is None
-    False
-
-If you try to grant access to a request token that's already been
-exchanged for an access token, you'll get a 400 error.
-
-    >>> response, content = browser.grant_access(
-    ...     username, password, request_token, access_level)
-    >>> print response.status

-Authorizing the request token
------------------------------
-
-There are also two convenience method which do the access token

-above to get a request token, and once it has the request token's
-authorization information, it makes the end-user authorize the request
-token by entering their Launchpad username and password.
-
-There are several ways of having the end-user authorize a request
-token, but the most secure is to open up the user's own web browser
-(other ways are described in trusted-client.txt). Because we don't
-want to actually open a web browser during this test, we'll create a
-fake authorizer that uses the SimulatedLaunchpadBrowser to authorize
-the request token.

-
-Here, we're using 'test_dev' as shorthand for the root URL of the web

-    should be opening in your browser. After you have authorized

-    back here and press <Enter> to finish the authentication process.

-***********************
-Making a trusted client
-***********************
-
-To authorize a request token, the end-user must type in their
-Launchpad username and password. Obviously, typing your password into
-a random program is a bad idea. The best case is to use a program you
-already trust with your Launchpad password: your web browser.
-
-But if you're writing an application that can't open the end-user's
-web browser, or you just really want a token authorization client that
-has the same UI as the rest of your application, you should use one of
-the trusted clients packaged with launchpadlib, rather than writing
-your own client.
-
-All the trusted clients are based on the same core code and implement
-the same workflow. This test implements a scriptable trusted client
-and uses it to test the behavior of the standard workflow.
-
-    >>> from launchpadlib.testing.helpers import (
-    ...     ScriptableRequestTokenAuthorization)
-
-Here we see the normal workflow, in which the user inputs all the
-correct data to authorize a request token.
-
-    >>> auth = ScriptableRequestTokenAuthorization(
-    ...     "consumer", "[e-mail]", "zeca",
-    ...     "WRITE_PRIVATE",
-    ...     allow_access_levels = ["WRITE_PUBLIC", "WRITE_PRIVATE"])
-    >>> access_token = auth()
-    An application identified as "consumer" wants to access Launchpad...
-    <BLANKLINE>
-    I'll use your Launchpad password to give "consumer" limited access...
-    What email address do you use on Launchpad?
-    What's your Launchpad password?
-    Now it's time for you to decide how much power to give "consumer" ...
-    ['UNAUTHORIZED', 'WRITE_PUBLIC', 'WRITE_PRIVATE']
-    Okay, I'm telling Launchpad to grant "consumer" access to your account.
-    You're all done! You should now be able to use Launchpad ...
-
-Ordinarily, the third-party program will create a request token and
-pass it into the trusted client. The test class is a little unusual:
-it takes care of creating the request token and, after the end-user
-has authorized it, exchanges the request token for an access
-token. This way we can verify that the entire end-to-end process
-works.
-
-    >>> access_token.key is not None
-    True
-
-Denying access
-==============
-
-It's always possible for the end-user to deny access to the
-application. This will make it impossible to convert the request token
-into an access token.
-
-    >>> auth = ScriptableRequestTokenAuthorization(
-    ...     "consumer", "[e-mail]", "zeca", "UNAUTHORIZED")
-    >>> access_token = auth()
-    An application identified as "consumer" wants to access Launchpad...
-    What email address do you use on Launchpad?
-    ...
-    Okay, I'm going to cancel the request that "consumer" made...
-    You're all done! "consumer" still doesn't have access...
-
-    >>> access_token is None
-    True
-
-Only one allowable access level
-===============================
-
-When the application being authenticated only allows one access level,
-the authorizer creates a special message for display to the end-user.
-
-    >>> auth = ScriptableRequestTokenAuthorization(
-    ...     "consumer", "[e-mail]", "zeca",
-    ...     "WRITE_PRIVATE", allow_access_levels=["WRITE_PRIVATE"])
-
-    >>> auth()
-    An application identified as "consumer" wants to access Launchpad ...
-    ...
-    "consumer" says it needs the following level of access to your Launchpad
-    account: "Change Anything". It can't work with any other level of access,
-    so denying this level of access means prohibiting "consumer" from
-    using your Launchpad account at all.
-    ...
-
-Error handling
-==============
-
-Things can go wrong in many ways, most of which we can test with our
-scriptable authorizer. Here's a utility method to run the
-authorization process with a badly-scripted authorizer and print the
-resulting exception.
-
-    >>> from launchpadlib.credentials import TokenAuthorizationException
-    >>> def print_error(auth):
-    ...     try:
-    ...         auth()
-    ...     except TokenAuthorizationException, e:
-    ...         print str(e)
-
-Authentication failures
------------------------
-
-If the user doesn't have a Launchpad account, or refuses to type in
-their email address, the authorizer will open their web browser to the
-login page, and raise an exception.
-
-    >>> auth = ScriptableRequestTokenAuthorization(
-    ...     "consumer", None, "zeca", "WRITE_PRIVATE")
-    >>> print_error(auth)
-    An application identified as "consumer" wants to access Launchpad ...
-    [If this were a real application, ... opened to http://launchpad.dev:8085/+login]
-    OK, you'll need to get yourself a Launchpad account before you can ...
-    <BLANKLINE>
-    I'm opening the Launchpad registration page in your web browser ...
-
-If the user enters the wrong username/password combination too many
-times, the authorizer will give up and raise an exception.
-
-    >>> auth = ScriptableRequestTokenAuthorization(
-    ...     "consumer", "[e-mail]", "baddpassword",
-    ...     "WRITE_PRIVATE")
-    >>> print_error(auth)
-    An application identified as "consumer" wants to access Launchpad...
-    ...
-    What email address do you use on Launchpad?
-    What's your Launchpad password?
-    I can't log in with the credentials you gave me. Let's try again.
-    What email address do you use on Launchpad?
-    Cached email address: [e-mail]
-    What's your Launchpad password?
-    You've failed the password entry too many times...
-
-The max_failed_attempts argument controls how many attempts the user
-is given to enter their username and password.
-
-    >>> auth = ScriptableRequestTokenAuthorization(
-    ...     "consumer", "bad username", "zeca",
-    ...     "WRITE_PRIVATE", max_failed_attempts=1)

-    What's your Launchpad password?
-    You've failed the password entry too many times...
-
-Approving a token that was already approved
--------------------------------------------
-
-To set this up, let's approve a request token but not exchange it for
-an access token.
-
-    >>> auth = ScriptableRequestTokenAuthorization(
-    ...     "consumer", "[e-mail]", "zeca",
-    ...     "WRITE_PRIVATE")
-    >>> auth(exchange_for_access_token=False)
-    An application identified as "consumer" wants to access Launchpad ...
-    ...
-
-Now let's try to approve the request token again:
-
-    >>> print_error(auth)
-    An application identified as "consumer" wants to access Launchpad ...
-    ...
-    It looks like you already approved this request...
-
-Once the request token is exchanged for an access token, it's
-deleted. An attempt to approve a request token that's already been
-exchanged for an access token gives an error message.
-
-    >>> auth.credentials.exchange_request_token_for_access_token(
-    ...     web_root=auth.web_root)
-
-    >>> print_error(auth)
-    An application identified as "consumer" wants to access Launchpad ...
-    ...
-    Launchpad couldn't find an outstanding request for integration...
-
-An attempt to approve a nonexistent request token gives the same error
-message.
-
-    >>> auth = ScriptableRequestTokenAuthorization(
-    ...     "consumer", "[e-mail]", "zeca",
-    ...     "WRITE_PRIVATE")
-    >>> auth.request_token = "nosuchrequesttoken"
-    >>> print_error(auth)
-    An application identified as "consumer" wants to access Launchpad ...
-    ...
-    Launchpad couldn't find an outstanding request for integration...
-
-Miscellaneous error
--------------------
-
-Random errors on the server side or (occasionally) the client side
-will result in a generic error message.
-
-    >>> auth.request_token = "this token will confuse launchpad badly"
-    >>> print_error(auth)
-    An application identified as "consumer" wants to access Launchpad ...
-    ...
-    There seems to be something wrong on the Launchpad server side...
-
-Client duplicity
-----------------
-
-If the third-party client gives one consumer name to Launchpad, and a
-different consumer name to the authorizer, the authorizer will detect
-this possible duplicity and print a warning.
-
-    >>> auth = ScriptableRequestTokenAuthorization(
-    ...     "consumer1", "[e-mail]", "zeca",
-    ...     "WRITE_PRIVATE")
-
-We'll simulate this by changing the authorizer's .consumer_name after
-it obtained a request token from Launchpad.
-
-    >>> auth.consumer_name = "consumer2"
-    >>> auth()
-    An application identified as "consumer2" wants to access Launchpad ...
-    ...
-    WARNING: The application you're using told me its name was "consumer2", but it told Launchpad its name was "consumer1"...
