I want to update the app in google app store.
But I can't download the code...
Is there any way to update the app without downloading the code?
I tried to download with python, google app engine SDK...
But
appcfg.py download_app -A
This command does not work giving this error
NameError: global name 'execfile' is not defined...
Can you help me with this?
The error you have shown may occur due to incorrect PYTHONPATH environment variable.
If you are using the Windows version of the GAE SDK, then do the following:
1) Go to Edit > Preferences
2) Correct your Python Path.
To know the Python Path in windows do the following in the Python IDLE or Python CMD:
import os
import sys
print os.path.dirname(sys.executable)
For downloading your source code try this:
download_app -A app_name -V version C:\path_to_project
You may or may not need to escape the backslash.
Replace app_name, version and C:\path_to_project with appropriate values
To know the version go to the app engine admin website appengine.appspot.com

I'm trying to test Google Cloud Storage to store images (I need it in an app that I'm developing) and I'm following the Bookshelf App tutorial that they have in his webpage.
I'm using python and the problem is that when I execute the requirementes.txt all packages have been installed fine, but when I try execute the code, I see this error:
...sandbox.py", line 948, in load_module
raise ImportError('No module named %s' % fullname)
ImportError: No module named cryptography.hazmat.bindings._openssl
I have been trying hundred of posibles solutions, reinstalling only the cryptography package, trying to use different versions of the same module, and installing other packages that contains it but anything resolved the problem.
The requirements contains this:
Flask==0.10.1
gcloud==0.9.0
gunicorn==19.4.5
oauth2client==1.5.2
Flask-SQLAlchemy==2.1
PyMySQL==0.7.1
Flask-PyMongo==0.4.0
PyMongo==3.2.1
six==1.10.0
I'm sure that it is a simple error but I don't find the way to solve it.
Any help will be welcome. Thanks.
EDIT:
When I try do this with a python program this work fine:
import os
from gcloud import storage
os.environ['GOOGLE_APPLICATION_CREDENTIALS'] = 'key.json'
client = storage.Client(project='xxxxxxx')
bucket = client.get_bucket('yyyyyyy')
f = open('profile.jpg', 'rb')
blob = bucket.blob(f.name)
blob.upload_from_string(f.read(), 'image/jpeg')
url = blob.public_url
print url
Why I don't can use gcloud library without erros in a GAE app?
It seems you're following the bookshelf tutorial, but according to this line in your stacktrace:
...sandbox.py", line 948, in load_module
It hints that you're using dev_appserver.py to run the code. This isn't necessary for Managed VMs/Flexible unless you're using the compat runtime.
If this is the case, the tutorial provides correct instructions:
$ virtualenv env
$ source env/bin/activate
$ pip install -r requirements.txt
$ python main.py
(If this is not the case, please feel free to comment on this with more details about how you're running your application).
I'm setting up remote_api locally and this time around it's not working. I'm just following the instructions on the remote_api doc page for python here: http://code.google.com/appengine/articles/remote_api.html
Which basically means I'm running the following command from the project app root (that contains app.yaml)
>> python $GAE_SDK_ROOT/remote_api_shell.py -s your_app_id.appspot.com
>> /Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python: can't open file '/remote_api_shell.py': [Errno 2] No such file or directory
The your_app_id param is being changed to the actual app id on google's.
It's probably a simple thing, but not sure what it is.
You need to replace $GAE_SDK_ROOT with the actual root directory of your GAE SDK. So, probably:
python ~/google_appengine/remote_api_shell.py -s ...
I have GWT app, which is deployed on GAE (Java). I'm trying to download data from App Engine datastore using appcfg.py . I did all the setup according to http://ikaisays.com/2010/06/10/using-the-bulkloader-with-java-app-engine/ .
GAE Python SDK version is 1.4.3
Python version is 2.5.4
appcfg.py is on my PATH. When I run appcfg.py on the command-line, I get the "help" message. But the problem is that no matter which command I use, it always returns the help message. I have not been able to run any command using appcfg.py.
It doesn't give any specific error message no matter what arguments I give. My app is using Google Accounts authentication, but I don't think it even gets to the point of authentication.
I'm able to use the Java appcfg (for other actions like rollback) without any problem. But the Python version simply refuses to work for all commands.
I've tried different formats like:
appcfg.py create_bulkloader_config --url=http://myappid.appspot.com/remote_api --application=myappid --filename=config.yml
appcfg.py create_bulkloader_config --filename=bulkloader.yaml --url=http://myappid.appspot.com/remote_api
appcfg.py --filename=bulkloader.yaml --url=http://myappid.appspot.com/remote_api create_bulkloader_config
All give me the same help message:
Usage: appcfg.py [options]
Action must be one of:
create_bulkloader_config: Create a bulkloader.yaml from a running application.
cron_info: Display information about cron jobs.
download_app: Download a previously-uploaded app.
download_data: Download entities from datastore.
help: Print help for a specific action.
request_logs: Write request logs in Apache common log format.
rollback: Rollback an in-progress update.
set_default_version: Set the default (serving) version.
update: Create or update an app version.
update_cron: Update application cron definitions.
update_dos: Update application dos definitions.
update_indexes: Update application indexes.
update_queues: Update application task queue definitions.
upload_data: Upload data records to datastore.
vacuum_indexes: Delete unused indexes from application.
Use 'help <action>' for a detailed description.
Options:
-h, --help Show the help message and exit.
-q, --quiet Print errors only.
-v, --verbose Print info level logs.
--noisy Print all logs.
-s SERVER, --server=SERVER
...
...
...
Even when I try "appcfg.py help create_bulkloader_config" for a detailed description, it still shows me the same standard help.
I have also tried on the local development server using the url http://127.0.0.1:8888/remote_api but it still gives the same help message.
I'm totally clueless as to what the problem is. I'm new to GWT and GAE, and any help will be appreciated.
Thanks.
The following fix worked for me. It looks like appcfg.py doesn't like PYTHON27 and ALWAYS returns the help menu. I fixed it by executing it with PYTHON25 and hard coded all my file locations:
C:\Python25-archive\python "C:\Program Files (x86)\Google\google_appengine\appcfg.py" rollback C:\scripts\myapp
The right way is to change the environment variables on Windows 7:
Go to System Properties
Go to Advance System Settings
Click on Environment Variables
Append to Path variable the values C:\Python27\
Click Ok and restart your computer. (Yes, it is needed.)
Another way is to:
Open command Prompt
Locate your python.exe file. For example:
C:\Python27>_
Then, run a python command that looks like this.
python <appcfg_directory> download_app -A <your_app_id> -V <your_app_version> <output-dir>
Where <appcfg_directory> is equal to C:\Program Files\Google\google_appengine\appcfg.py. (Depending on your file location)
Don't forget to put quotes before and after <appcfg_directory>
This seems like it should be very easy but I don't see a link to it anywhere.
How do I download the source code of a google app engine project?
Windows
appengine-java-sdk\bin\appcfg.cmd -A <your_app_id> -V <your_app_version> download_app <output-dir>
Linux
./appengine-java-sdk/bin/appcfg.sh -A <your_app_id> -V <your_app_version> download_app <output-dir>
For completeness, using the Python implementation:
appcfg.py download_app -A $appID -V $appVersionNumber $downloadDirectory --oauth2
--oauth2 is of course optional, you can omit it and provide your email + app-specific password (or your password, and then go implement two-factor authentication right after), but it's easier, and frankly there's no reason not to.
Documentation.
App Engine actually recently added the ability for the developer who uploaded a given app version to download its source code.
As of October 2019 you can simply go to --> App Engine --> Services and in the tool dropdown select 'source' and the source code is there
Posting this since none of the listed methods above didn't take me to the code (by June 2021)
You could try accessing it through;
Google Cloud Platform > Debugger > choosing the version of the
Application from combo at top.
This will list the files of that version on the left pane. There is no way to download it automatically but you can copy-paste the code.
Hope you will find this helpful.
IMHO, the best option today (Aug 2018) is:
Under the main menu, under Products, go to Tools -> Cloud Build -> Build history.
There, click the ID of the build you want (for me - the last one).
Then, in the opened window (Build details), click the "source" link, the download of your compressed code begins.
As simple as that.
HTH.
Working with App engine standard using Go, the debugger isn't available yet.
How I managed to download the source code for an existing service was to use the gcloud tool.
First: Get the version id of your service using the app engine console or running: gcloud app versions list
Second: use the version and service name and run: gcloud app versions describe <versionID> --service=<service name>
the describe parameter will give you the storage locations for your source files that looks like this:
cmd/main.go:
sha1Sum: e3fe5848c2640eca7ac3591490e1debc2d3a9b09
sourceUrl: https://storage.googleapis.com/<project>/<file id>
Third: you can then use the storage console, using the file id, to download the files you are interested in.
this process based on java sdk
Its works for me...
Download Google cloud SDK
gcloud init
enter image description here
Follow through process of logging in using your credentials
Enter following command from SDK
C:\Program Files (x86)\Google\appengine-java-sdk-1.9.49\bin
enter image description here
Enter Following command to download source code
appcfg.sh -A [YOUR_APP_ID] -V [YOUR_APP_VERSION] download_app [OUTPUT_DIR]
Eg: appcfg.sh -A my-project-name-1234 -V 2 download_app C:\Users\india\Desktop\my project
Note: this progress based on java-appengine sdk so we use appcfg.sh instead of appcfg.py
check if your app is uploaded with same email id that is in your app engine. if you are not sure then in app engine > control > Clear deployment credentials and then click on any project, deploy to sign in again then use this
appcfg.py download_app -A {app id from google app engine} -V {1} "{c:\path}" --oauth2_credential_file=C:\Users\{your account name}/.appcfg_oauth2_tokens
change all {} to your needs
Things have changed since this question was asked so I'm adding an updated answer. Note that this only applies to GAE Standard Environment
Google has deprecated appcfg.py and so the previous responses appcfg.py download_app no longer works.
gcloud which is the SDK in use (it replaced appcfg) does not have the functionality to download your source code.
When you deploy your app via gcloud app deploy, it copies your source code to a bucket. The default bucket is staging.<project_name>.appspot.com. Your files will stay in this bucket for a maximum of 15 days before they are deleted. You can modify the rule so that the files are retained for longer or less time.
The file names in the bucket are encoded so you can't figure out what each file is unless you open it (i.e. download it). Google has a mapping of the encoded names to the original file names. To get this mapping, you run the gcloud app versions describe command and it will list the file names and their encoded names. To download the files, you have to manually click each url one by one. So essentially, you have to download each file manually and then use the mapping to rename them (or open the file, check the content and then rename them). Also note that downloading the files manually will not maintain the folder structure in which they were uploaded.
If you do not wish to go through all of the above hassles (imagine having to manually open each url for each file if you have a small to mid-sized project which has hundreds of files), our App - https://nocommandline.com - now supports downloading source code from the default bucket - staging.<project_name>.appspot.com (so far as your files are still there which means any deployment i.e update not older than 15 days from your current date unless you previously increased the deletion age on your staging bucket's lifecycle page).
In simple terms, you enter your project name, the version number and our App will take care of retrieving the original file name to encoded name mapping, automatically downloading the files and renaming them to the original names, while maintaining the folder structure. For more information, refer to https://nocommandline.com/help/#faq_download_source_code_from_gae.
Log in to the console.developers.google.com
Select the project you want to download the code from (Google App Engine Standard Envoronment).
Go to the App Engine Dashboard. Under Summary is Debug and Source. Click on Source.
Select each file one at a time and copy it (highlight the code, copy and paste into your local editor.)
Select the next file....
You need to use svn to checkout the files.
If you are on Windows, you can use tortoise svn for your GUI end.
Here are tutorials on how to do it, here is the related question.
I need to download the application files that are deployed using command prompt into google appengine server.
if anybody know about this plz tell me!
thanks in advance!
SDK 1.4.0 has this sort of feature (Python only):
The developer who uploaded an app version can download that version's
code using the appcfg.py
download_app command. This feature can
be disabled on a per application
basis in the admin console, under the
'Permissions' tab. Once disabled,
code download for the application
CANNOT be re-enabled.
Note that although the 'download_app' command is only available in the Python SDK, it can be used to download Java applications from App Engine. If you have a Java app that you want to download, just do:
Install Python (version 2.x only), if necessary.
Install App Engine 1.4.0 (or higher), Python version.
Run the python download_app command as described in the documentation, like appcfg.py download_app -A <your app name> -V <version to download> <path to download to>.
Your Java app will download. Hooray!
It's not possible to download your code from App Engine, unless you included code to support it when you uploaded your app. You can download static files by simply fetching them, of course.
To achieve this, you need to use a source control system, such as SVN or Git, and store/retrieve your code from there - App Engine isn't intended to act as source control.
You can use appcfg.sh / appcfg.cmd in your GAE SDK, as pointed out in this official guide.
But notice that as of 2012-05-07, at least for the Windows version appcfg.cmd, the command's syntax is
appcfg -A yourappid -V yourversionnumber download_app c:\path\to\download\directory
Also notice that when you run this command and you get asked for your password and you happen to have activated Google's 2-step verification, you must not provide your Google password, but instead must provide an application-specific password (which you can generate on this side)
As explained in this post: http://www.labnol.org/software/download-appengine-files/19348/
App Engine 1.5.0 introduced the feature to download your source code.
The command is:
appcfg.py download_app –A MyAppName -V 1 c:\AppEngine\SourceCode
You can use appcfg.py with download_data option, see docs.
You can download an application's source code by running appcfg.py with the download_app action in the Python SDK command-line tool:
appcfg.py download_app -A <your_app_id> -V <your_app_version> <output-dir>
