Getting "Error connecting to the service protocol:" even on API 28

Trying to run  Flutter app on Android Tablet emulator with API 28. I mention the emulator being API 28 since some other answers I have seen around just suggest to downgrade from API 29 to API 28 and it should work...not my case.
App does not start and crashes with error:
Error connecting to the service protocol: failed to connect to http://<IP_ADDRESS>:52825/MAfZ5Zc4A4E=/

Hi @andreddie81
do you experience this with latest stable v1.12.13+hotfix.8?
I can't reproduce it with it.
Or with newer versions - latest dev or beta?

Hi, I have not tried with any other Flutter version, shall I just run flutter upgrade ??
In case I run flutter upgrade ?? how would I go back to my current Flutter version if needed?
Thanks for the answer!

@andreddie81
yes, flutter upgrade. To downgrade you need to run from your flutter directory git checkout v1.12.13+hotfix.5 and then flutter doctor
To change channel you can run flutter channel dev or flutter channel beta or flutter channel stable and then flutter doctor

I did flutter upgrade and still same error...do you have any other idea what can be causing this?
my flutter doctor now:

@andreddie81
can you run with other any other device/simulator/emulator?

real device android 9 works without problem but not in any other android emulator with any other API 27, 28, 29

@andreddie81
could you provide flutter run --verbose with emulator?

here it comes...its huge, looks like at the end throws some sort of exception

[   +2 ms] "flutter run" took 14,296ms.

Dears, any update on this issue.
I did research all the topics about this on Google Search and seems everyone is providing a possible solution that worked for them but not for others. Tried all the provided solutions but no luck.
I'm experiencing the same intermittent problem.
Need to reboot system several time a day to get it working again and after some tests it fails all over again.
This is becoming a non workable development env.
See error below.

oci-image-tool: more verbose output

From @s-urbaniak on August 30, 2016 12:55
As per https://docs.google.com/document/d/1bsi9JCnmOMSZCDh3VmDCO1m17w1aNexX09naomcpUOs/edit the oci-image-tool should have more verbose output, more concretely:
Print ...

[ ] the digests of objects
[ ] the version of the spec tested against
[ ] canonical mimetypes and alternative
[ ] the version of the validator code
[ ] a list of tests that were ran
[ ] a list of errors

I did implement the last point ("a list of errors") actually already, so I am wondering what additional requirements are needed here.

From @s-urbaniak on August 30, 2016 14:51
@runcom thanks for the help! Sure, just go ahead, I'll try tackle each of those in parallel with other rkt work. Just let me know if you want to tackle all of them or just a subset. Seem like low-hanging fruits to me.

@s-urbaniak If it need to be done based on #159 ?
It refactor the image tool completely. If we did before it is merged, we may be meet a big conflict.

I'm all for avoiding conflicts, but #159 tries to stay away from the
existing image-validation logic.  So I expect you can wade into these issues without butting heads with #159.
My long-term plan was to land #159 and then rewrite the
validation/unpacking logic to use callback registries.  Something
like:
type Validator func(ctx context.Context, engine cas.Engine, ref specs.Descriptor, recursive bool) (errors []string)
var Validaters map[string]Validator {
"application/vnd.oci.descriptor.v1+json": ValidateDescriptor,
"application/vnd.oci.image.manifest.v1+json": ValidateManifest,
"application/vnd.oci.image.manifest.list.v1+json": ValidateManifestList,
…
}
But I don't have any work in progress on that front, so there won't be
any conflicts if validation shifts around in the meantime ;).

Is this related to https://github.com/opencontainers/image-tools/issues/14? Should we first introduce a logging framework and then add logs for the above cases?


Date format from geoserver

Date, that returned from Geoserver, contains "Z" on end of string, "2015-10-15Z".
  types: ['date', 'time', 'datetime'],
      parse: function (input) {
        return new Date(input);
      }

In Chrome this work good, but in IE11-12, browser cant parse that (invalid date), need to remove "Z".
something like this
if (input[input.length-1] == "Z") {input = input.substring(0, input.length - 1)};
return new Date(input);

Dont sure, is this correct

msdn says that IE can parse this dates, but in examples its presents with time...


Using cached properties in Python libraries breaks keyword discovery

I am working on a Python keyword library that uses the @functools.cached_property decorator to lazily initialize parts of the keyword library on first use. Here's a simplified example of the pattern I'm using:
import functools

class KeywordLibrary:
    @functools.cached_property
    def _lazy_property(self):
        # some expensive init logic here

    def first_keyword(self):
        pass

    def second_keyword(self):
        pass

However, it seems that this approach does not work with the way Robot discovers keywords: for some reason the property is evaluated while Robot is looking for keyword names, causing the initialization logic to run while the library is being imported...
I tried telling Robot that my property is not actually a keyword, and according to the documentation, there are four ways of doing this:

Prefix the method with _
Add the @robot.api.deco.library annotation to the Python class
Set ROBOT_AUTO_KEYWORDS = False as a Python class member
Add the @robot.api.deco.not_keyword annotation to the method

Of these options, only the last one caused Robot to stop evaluating my method, which seems like a bug to me.

I added a reproduction scenario below. The method is already prefixed with _, and adding @library or ROBOT_AUTO_KEYWORDS = False results in the same error.
import functools

class CachedPropertyLibrary:
    @functools.cached_property
    def _private_property_stay_away(self):
        raise RuntimeError("You should not have called me, Robot!")

    def do_nothing(self):
        pass

*** Settings ***
Library    CachedPropertyLibrary

*** Tasks ***
Sample task
    Do nothing

Gives the following error:
==============================================================================
Tests
==============================================================================
Sample task                                                           | FAIL |

[ ERROR ] Error in file '...' on line 2: Getting keyword names from library 'CachedPropertyLibrary' failed: You should not have called me, Robot!

Note that a property that is manually cached does not run into the same issue, for example this works:
class KeywordLibrary:
    def __init__(self):
        _lazy_property_value = None

    @property
    def _lazy_property(self):
        if not self._lazy_property_value:
            self._lazy_property_value = # some expensive init logic here
        return self._lazy_property_value

    def first_keyword(self):
        pass

    def second_keyword(self):
        pass

Interesting. We have code to avoid calling properies, but apparently that doesn't work with cached_property. This code was enhanced in RF 6.1.1 to avoid issues when using property with classmethod. Have you tested with that version?

Thanks for the heads-up! We are currently using RobotFramework 6.0.2 which is where I encountered the issue. I just ran the reproduction code with RobotFramework 6.1.1 and indeed the error no longer occurs.

Thanks for the update. Apparently the fix for #4802 resolved this issue as well. Good that I made a generic fix and didn't just special case classmethod. I think it makes sense to add a separate test for cached_property before closing this issue. Hopefully you can upgrade to RF 6.1.1 easily.

I think it makes sense to add a separate test for cached_property before closing this issue.

Yes I agree. I would like to contribute this if you don't mind. However, I'm struggling to understand whether I can simply add this as an extra case to the existing avoid_properties_when_creating_libraries.robot since using cached_property is only possible for Python >= 3.8. Do you maybe have an example that I can base it on?

Actually, looking at the source of cached_property, I'm inclined to say that the existing test cases for a custom non-data descriptor cover this issue well enough. There is a multitude of other similar annotations that are also not explicitly tested, so I'm not sure adding tests for cached_property is really needed.

According to #4915 cached_property is still accessed, earlier changes just hide possible exceptions. I should have created a separate test for them. Anyway, the problem will be fixed for real in RF 7.0.

Fix display pixelclk active

On the RT1170-EVKB, the framebuffer displays incorrectly (shifted by about 1/4 of the screen width). This is because pixelclk-active was set to 1 which corresponds to kELCDIF_DriveDataOnRisingClkEdge.
According to the HX8394 datasheet, it should be set to 0 which corresponds to kELCDIF_DriveDataOnFallingClkEdge.

Hi @danieldegrasse,
Could you take a look, please ?
Thanks.

@erwango, can you review and approve so we can get this merged?


Is this typical noise for the L515?

Required Info

Camera Model
L515

Firmware Version
<IP_ADDRESS>

Operating System & Version
Windows 10

Viewer Version
2.38.1

Issue Description
Hi,
The datasheet for the L515 says that at 1m range (of a 95% reflectivity object), the accuracy is <5mm and the std deviation of the noise is 2.5mm. We'd expect 99.7% of the samples to be within 3 std deviations, and so (most of) the noise should be within +/- 7.5mm.

I've taken some test scans, and I'm wondering if the noise I'm seeing is typical. Or could there be something wrong with my device?
This is the scanner looking directly at a light coloured wall, from about 1m.

The scan has numerous ripples running through it. The ripples undulate constantly (like a waving ocean). Is that normal?

In this picture I have a couple of test objects on my floor. A red box about 13x9cm and about 3cm thick, and a white rock about 4x6cm and about 2cm thick.

This scan is from about 75cm above the floor. I'd expect noise (up to 7.5mm for 3 std devs) to be less than 1/4 the thickness of the box, or 1/3 the thickness of the rock. The ripples in this scan are generally not very large. The shape of the red box is fairly clear. However, the rock is quite distorted (passing below the floor). Could this be related to the curvature of the rock?

These are the same two objects on some dirt/gravel ground.

This is the corresponding scan, from about 75cm. Note that this ground was quite low in reflectivity, I had to get closer to it (under 1m) for it to be clearly visible in the scan. In this scan the rippling noise is quite extreme, and while the box is visible, the white rock is unrecognisable in the noise.

Does this look roughly like the expected behaviour of the scanner, or could something be going wrong here?
Thanks,
Saxon

I too am curious about the noise under ideal conditions. I will let others speak to that. One issue I noticed is that your last image looks like it is in ambient sun light. In my hands any sunlight will increase noise and consequently decrease range. I have resorted to using VGA mode and really minimizing any sunlight in the scene.

I just thought I'd include a gif of the noise on the flat wall (the first scan above), to better show what I mean:

Yes @blakely3dnm the last photo was taken outside in sunlight. Although, it was a cloudy overcast day (it was about to rain) and also later in the afternoon, so it wasn't direct sunlight just ambient light. Overall it was probably about as light as a reasonably well lit indoor space. Have you seen even ambient light outside cause problems, as opposed to direct sunlight?
Thanks.

Here also is a gif of the noise in the indoor scene on the floor. In this scan the objects are about 85cm away. The scan is on an angle - the near part of the floor is at about 60cm, the far part at about 110cm.

What is your sensor gain for the short range tests you are doing? Check this post for more ideas:
https://www.intelrealsense.com/optimizing-the-lidar-camera-l515-range/
And yes, in my experience ambient light through clouds will have enough IR light to cause problems. It is not the visible light that causes problems, so you could use it in a well-lit room just fine as long as there are no IR sources.

Also including direct link to the User Guide:  https://www.intelrealsense.com/download/13061/
Tuning the device for various situations may result in better images as outlined in the optimizing page as well as the L515 user guide.  Ambient light also will influence the resulting images as well.

Is there anything more needed on this thread?
*If we don’t hear from you in 7 days, this issue will be closed.

I had been meaning to come back to post that I had done some additional tests at night time, and the noise was much better.
This was my test scene:

My test objects were:

red box about 13x9cm and about 3cm thick
white rock about 6x4cm and about 2cm thick
grey rock about 6x5cm and about 2cm thick
brown rock about 7x6cm and about 4cm high at the peak

The L515's camera didn't really pick up much colour (my phone does a better job in the photo above), but the depth is pretty good with much less noise than my earlier scan during day time:

Also for reference here it is coloured by depth:

These scans were made using the default settings for sensor gain.
My previous indoor test scans were done at daytime in a room a few metres from a large window, so I think this was also the cause of some of the added noise for the indoor scene.
Thanks @blakely3dnm and @RealSenseSupport for the info about avoiding sunlight as much as possible.

Glad you're able to get better depth information and data.  Thanks for following up and letting us know.

Fix Regression: the type resolution error if an user project uses tsc with moduleResolution=node16

This reverts commit d78460aa907f4c1ea19622b9ae5c94a6b4d976d0. #1409
If we set type in package.json to module, an user project which uses typescript with moduleResolution=node16 will cause an type resolution error.
I guess tsc has some bugs. So we need to workaround.
Reopen https://github.com/karen-irc/option-t/issues/816

I guess tsc has some bugs. So we need to workaround.

This was not a tsc's bug.
tsc requires an extension for import statement in all d.ts file too if type=module and moduleResolution=node16. But our generated code does not have an extension.


Modules: GLMakie extension

Make an extension module for visualising the data with GLMakie

[ ] volumeslices should use the PostProcessing module to gather data to rank 0 and plot
[ ] contour should call isosurface extraction and MPI gather from the PostProcessing module

Ideally this should also work with CairoMakie for running on servers.

Ideally this should also work with CairoMakie for running on servers.

Good point, it's actually just a Makie extension, not GLMakie in particular =)

DbEnum macro results in "unresolved import"

Hey there
I try to use the derive enum macro with diesel master (2.0.0-rc.0) but when trying to define an enum, the compiler complains about an unresolved import:
use diesel::prelude::*;
use diesel_derive_enum::*;

#[derive(Debug, PartialEq, DbEnum)]
#[DieselType = "LanguageEnum"]
#[PgType = "language"]
pub enum Language {
    De,
    Fr,
    It,
    En,
}

When trying to use this enum above, the compiler returns:
246 | #[derive(Debug, PartialEq, DbEnum)]
    |                            ^^^^^^
    |                            |
    |                            unresolved import
    |                            help: a similar path exists: `crate::database::schema`

Could someone point me into the right direction?

Mmm the README is now out-of-sync with the master branch, I need to get around to updating it.
The TLDR is you have to specify DieselExistingType not DieselType, see: https://github.com/adwhit/diesel-derive-enum/blob/e6aa69856245f083645a0087527236a6bff42c18/src/lib.rs#L17


CSS not work

I am add  datatable-bootstrap.css but the style is not active for pagination

You must only include the datatable-bootstrap file. Which version of Bootstrap are you using?

I'm use Bootstrap 4!

If you are using Bootstrap 4, you need to customize some options, in particular:
pagingItemClass: 'page-item',
pagingLinkClass: 'page-link',
pagingLinkDisabledTabIndex: true

Thanks you!

cp -r semantics

Currently, cloudfiles cp -r differs from cp -r because unlike with a regular filesystem, object storage doesn't have a convenient mv command. So where cp -r copies the directory and the subfiles, cloudfiles cp -r copies only the subfiles to allow you to specify the level of hierarchy in the destination path.
However, this has caused confusion for several users. Perhaps we could allow cp -r to follow POSIX semantics while allowing cp dir/** to work like before.

Maybe for comparison, gsutil: https://cloud.google.com/storage/docs/gsutil/commands/cp#how-names-are-constructed - I think that's what lab members are probably already familiar with.
aws s3 cp also has a useful --dryrun argument


Could not schedule look to slack channel

I followed the steps in
https://github.com/looker/looker-slackbot#scheduling-data-to-slack
to set up the webhook, and pretty sure have the LOOKER_WEBHOOK_TOKEN set up with "Outgoing Webhook Token" from Looker admin panel.
I tried to "sent test" of a look (not dashboar) with single big number on the look. The service has the access to the space. No warnings show up, and it says "On its way!". Didn't see the msg in slack channel (server to slack is working for slash_command already) and no logs from server side.
Is there any place I can look into to debug? Thanks!

thanks @wilg!
y, I saw some logs from looker :

Could not send a webhook (Webhook ID: fb65d3424483223b683e0033fdcbc2dc) to [URL]/slack/post/channel/s-metrics

2017-03-09 19:36:42.167 +0000 [ERROR|00b2c|webhook] :: Error posting to WebHook. No response given.

Looks like an SSL connection problem. Some things to check:

Is your bot host using HTTPS?
Does your bot host have a valid certificate?
Does the certificate use SNI (https://en.wikipedia.org/wiki/Server_Name_Indication)? This is the case with some CloudFlare SSL certificates and Looker's webhook system does not currently support SNI.

@wilg thanks for the quick reply!
Seems that's the case, let me check whether I can use the cfs deployment.

Deployed the service to CloudFormation and solved the problem.
Thanks very much @wilg !

I feel like there's some context missing here.  @alexbao mentioned the cfs deployment.  What cfs deployment is being referred to?  Is there any documentation about setting up looker-slackbot with SSL on EC2?

There's no docs specific to looker-slackbot with SSL on EC2, no. Not sure exacrtly what @alexbao's issue was or how it was solved, but the above steps are a good thing to check if you're having similar issues.

@wilg is there any configuration that needs to be done to allow the bot to work with SSL, or does that just work with default settings on the bot, as long as there is a cert on the host?
Thanks!

@rsmichaeldunn Slack requires that Slash commands (and other potential future types of notifications from Slack to the bot) use SSL with a valid certificate. Looker requires the same for receiving scheduled webhooks and data actions.
The bot doesn't provide an SSL server out-of-the box, it's meant for the SSL to be applied by a proxy (this is how Heroku does it and some of our own internal infrastructure). That's usually the easiest way to apply a cert to the bot.
It's still possible to minimally use the bot without slash commands or scheduling without the bot running as a server publicly accessible to the internet, because it will just open a connection to Slack's RTM API and doesn't need inbound connections for the basic features.
