[google-appengine] Re: gcloud vs. goapp for GO appengine

['Adam (Cloud Platform Support)' via Google App Engine]

You can still keep the standalone SDK installed alongside gcloud and use 
the goapp workflow if you prefer. The 'goapp' installed by gcloud resides 
in a directory outside of the PATH on purpose so as not to conflict with 
the standalone SDK, and is meant to be invoked only by gcloud. The 'goroot' 
directory is the same goroot that is included in the standalone SDK. It's 
best not to try and mash parts of the SDKs together or expose internal bits 
of gcloud and try to use them like the standalone SDK.

The different ways to deploy a standard environment Go app (goapp, gcloud, 
or appcfg) are given in the documentation Deploying a Go App. 
 As 
to where your app should reside, you should always keep your app sources 
outside of the SDK directory tree, so which SDK you use should not matter.

[google-appengine] Re: The New version of App Engine?

['Adam (Cloud Platform Support)' via Google App Engine]

The lwip library is failing to build libpng, which it depends on. The error 
mentions "see the notes in pngpriv.h". If you check the comments in that 
source file 
 
they say this:

#  error ZLIB_VERNUM != PNG_ZLIB_VERNUM \
  "-I (include path) error: see the notes in pngpriv.h"
   /* This means that when pnglibconf.h was built the copy of zlib.h that it
* used is not the same as the one being used here.  Because the build of
* libpng makes decisions to use inflateInit2 and inflateReset2 based on 
the
* zlib version number and because this affects handling of certain 
broken
* PNG files the -I directives must match.
*
* The most likely explanation is that you passed a -I in CFLAGS. This 
will
* not work; all the preprocessor directories and in particular all the 
-I
* directives must be in CPPFLAGS.
*/

Do you get this error when running 'npm install' and testing locally, or 
does it only occur when running 'gcloud app deploy'?

[google-appengine] Re: My custom domain redirect user to https://applicationid.appspot.com when i enable ssl

['Adam (Cloud Platform Support)' via Google App Engine]

You'd want to troubleshoot one thing at a time. Forgetting the  'secure: 
always' redirect, what happens when you just try to access your domain via 
HTTPS directly after configuring SSL? If that doesn't work, there's a 
problem with your SSL config, not the redirect.

Remember that you actually need to add specific DNS records to your 
domain's DNS configuration at the step 'Configure resource records for your 
domain' (see step 5 and 6 in the documentation 
).
 
If you've done this, DNS records also need time to propagate. You can check 
propagation by using a tool like https://www.whatsmydns.net.

[google-appengine] What's the difference between .app and .py?

['Jon Wayne Parrott' via Google App Engine]

Because it's a reference to a specific object within that Python file. It's 
essentially the same as "from main import app". app engine uses the "app" 
object within "main.Py" to handle requests.

[google-appengine] Re: Google App Engine NodeJS log severity

['Adam (Cloud Platform Support)' via Google App Engine]

Actually, when browsing the sources for google-cloud-node I discovered 
there is now a new winston transport being developed - 
*@google-cloud/logging-winston 
*.
 
Usage is greatly simplified:

var winston = require('winston');var transport = 
require('@google-cloud/logging-winston');
winston.add(transport);

winston.error('warp nacelles offline');winston.verbose('sheilds at 99%');

 The standard winston  logger

 severity in the Logs Viewer.

[google-appengine] gcloud vs. goapp for GO appengine

[Tim Becker]

Sorry if I'm missing something obvious, but it seems that the documenation 
is very unclear about this and was just recently changed with no clear 
migration instructions:

   - since recently (~ last week sometime) the prefered way to install 
   Golang support seems to be via the "Google Cloud SDK" (vs the "original App 
   Engine SDK for Go")
   - previously, the `goapp` tool was a central part of my workflow in 
   order to deal with the dependency on the completely outdated 1.6 version of 
   Go required by appengine
   - using gcloud and installing go support via `gcloud components install 
   app-engine-go` gets me two `goapp`s:
   -  ./google-cloud-sdk/platform/google_appengine/goapp
  -  ./google-cloud-sdk/platform/google_appengine/goroot/bin/goapp
   - the first of which is a python script with no executable bit set, and 
   neither of which are in the PATH set up by the install.sh script
   - running, eg. 
   `./google-cloud-sdk/platform/google_appengine/goroot/bin/goapp test` 
   results in the following error:
  - `go: cannot find GOROOT directory: 
  
/private/var/folders/bs/nn10qt5j32g25qwgd77wkcyh00d7l1/T/appengine/go_appengine/goroot
   
Now there are `gopath` and `goroot` dirs in the 
`plattform/google_appengine` directory and I'm tempted to set the 
corresponding environment variables to point to those directories, because 
at least `goroot` seems to have all the necessary appengine dependencies 
install in it. But this leaves me wondering, where my app should reside. 
And dealing with appengine/gcloud/whatever it's called today in this manner 
feels just like "trying out random stuff"

The README contains completely outdated info from 2008. And the online docs 
only seems to focus on using the "classic" SDK 
(e.g. 
https://cloud.google.com/appengine/docs/standard/go/tools/localunittesting/)

Is there any obvious documenation that I'm missing? Am I the only person 
encountering these problems?
