Propagate MotoHost via env vars to Lambda

FYI @kbalk - this adds the env vars to the Lambda Docker container per your suggestion.
Marking it as draft for now, as the tests will probably fail..

♥ You're my hero, Bert!
There's still documentation needed so people can use this and I still need to debug the issue of running that lambda within another docker container.  I don't know if it's because the docker container doesn't support a nested container or what.
Also, the issue https://github.com/spulec/moto/issues/1108 might not be resolved by this PR, but it might be useful to link this PR to it because it's related.

I just ran into an issue where I could only execute a Lambda as long as the host container was called motoserver - something to do with the links-argument here: https://github.com/spulec/moto/blob/master/moto/awslambda/models.py#L578

Wow, you must have to dig to find that!   I got a "volume busy" error, which is why I was thinking it was a nesting issue.  I'm also concerned that once I get the lambda running, I might need something like LocalStack's DOCKER_BRIDGE_IP as the hostname to reach the moto server.
I've got to put in some regular work hours today, so I won't be able to debug until much later tonight.

I don't get the "volume busy" message and the lambda actually tries to execute.  I don't really have the right testing environment because I'm not going into the docker container to replace the version of moto installed by LocalStack.  However, I think what I'm seeing correlates with what you were saying about the container name?
When I run my test, the container name is "localstack", which is the value we assign to LocalStack's environment variable MAIN_CONTAINER_NAME in the docker compose file:
services:
  localstack:
    container_name: localstack
    image: localstack/localstack
    ports:
      - "4566:4566"
      - "4615:4615"
      - "4571:4571"
    environment:
      - MAIN_CONTAINER_NAME=localstack.   <---------------------------------
      - LAMBDA_DOCKER_NETWORK=terraform_pytest_default
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock"
      - "${TERRAFORM_PYTEST_DIR}/initaws.d:/docker-entrypoint-initaws.d"

LocalStack's README defines that as:
MAIN_CONTAINER_NAME: Specify the main docker container name (default: `localstack_main`).
We use that same name to set the host value in the provider file.  So the lambda endpoint would be http://localstack:4615, where 4615 is the moto port.
When the container is spun up and the Terraform test is executed within that container, the test fails with the Terraform message:
module.success.aws_cloudformation_stack.cfn: Refreshing state... [id=arn:aws:cloudformation:us-east-1:123456789:stack/ami-lookup-test-complex-search/aadc7ef3-c402-4fd4-97e0-4a11bb2b5ecf]

The moto log events for the test show a status of SUCCESS from the lambda, then:

Is there a way we could pass the container name to moto?  We pass the port number to the server, could we pass a container name?
Also, I just realized that the test for "motoserver" you referenced is just a few lines down from where the env vars was set.  So not so hard to find, but I didn't recognize the significance of that test.

Yeah, that makes sense, using the same mechanism. I'm not sure why it wouldn't have a host though, it should always default to host.docker.internal if nothing else

I'll try to debug it tonight or see what more I can figure out.

I should have provided more of the logs in my previous comment.  Here's a snippet that's before the snippet I previously sent you:

The above snippet is coming from the print statements in moto/packages/cfnresponse/cfnresponse.py and it shows that the send() function was passed a bad url in the event.
The only place where "cfnresponse" would be put in a URL is in moto/cloudformation/custom_model.py in the function create_from_cloudformation_json():
        host = f"{settings.moto_server_host()}:{settings.moto_server_port()}"
        response_url = (
            f"{host}/cloudformation_{region_name}/cfnresponse?stack={stack_id}"
        )

I added print statements to show the output of settings.moto_server_host() and settings.get_docker_host(), but because moto is running in a docker container, I can't see the print output.  The modified moto is only being pulled in when the lambda runs.
So I added a new entry to the event that's passed to send().  That new entry contains the output of settings.get_docker_host() and I print that from send(), but it's not showing up on the dashboard.  It should, so I don't know what I'm doing wrong.

FYI @lorengordon I've added the option to change network_mode, per the discussion in #4638
https://github.com/spulec/moto/pull/4658/files#diff-908971deae8555292db0b80849241c2820db44529d71374f90212ed027c54f87R1133-R1144

I see, thanks @bblommers! I'm not entirely sure if setting network_mode=host will work for our use case, with a user-defined network bridge, but I suppose it might. Hadn't thought of that. I was more thinking that we would pass network=<user-defined-bridge> to connect the lambda container directly to the network bridge...

This is a ridiculously hard thing to debug.  I'll give it one last try tomorrow.  I tried "updating" the container running LocalStack and moto, but the test then hung.
In moto/awslambda/models.py (arround line 1137) there is no longer a mention of MOTO_PORT. Instead the example shows a hard coded value for the port. Is there a reason you did that?

Just a suggestion - is it easier to create testreleases? You could checkout the branch, change the projectname to 'myfirstmotoproject' and push your own release to PyPi, and then incorporate that release as a normal dependency. It could speed up the debug/release/test cycle.

The first example still uses MOTO_PORT, only the second example uses a hardcoded value, to remind people that this option always exists

The problem is LocalStack running within the docker container.  It's pulling in a specific version of moto, which is not the version I want it to use.  I'm going to have to look at how it starts up and see if I can insert the 6 files you changed (one needs a modification for a file it imports) and restart moto.  When I run LocalStack and moto from the command line I can usually restart moto without restarting LocalStack and it works fine.
It sounds terrible (as in there should be a better way), but it might be easier to wait until LocalStack uses a version of moto with this change and then see if I can get it to do what I need it to do.

Ah ... I was looking at the individual commit, not the differences in their entirety.

The problem is LocalStack running within the docker container. It's pulling in a specific version of moto, which is not the version I want it to use.

@kbalk perhaps we can update the init script that starts the moto server to optionally install moto? If you fork localstack/moto, merge these changes, then you could install using python -m pip install git+https://github.com/kbalk/<forkedrepo>.git@<branch>

LocalStack is using their own fork of moto and I noticed a change to an import when I was diffing the files I wanted to add to the docker container.  So maybe they pull in the latest released version of moto, yet make changes to it?   Since I'm not really using LocalStack except to hook up the endpoints, I suppose I could just drop in a new version of moto like I would from a command line?  I'll do a little digging and experimenting.

I stopped worrying about what LocalStack was doing with moto and that made things much simpler.  I modified the initaws.d/start.sh script as @lorengordon suggested, but I commented out the line to start moto.  I copied the moto wheel to the LocalStack docker container, installed flask, flask-cors and the docker python module, then manually started up moto_server.  So now I can run moto_server from the command line in the docker container.
moto is crashing in the code I mentioned before (moto/cloudformation/custom_model.py).  moto_server_host() is calling get_docker_host() and the ip value is null.  The IPAddress we want is nested under the info for the docker network bridge we named "terraform_pytest_default"

@bblommers I tested the following code change, but if you write it differently, I can retest it for you.  I'm not sure how to the handle the case where they give you a bad network name.  It might be better to raise an exception if the network name can't be found in the networks versus ignore it.  I'd wouldn't want to have to debug a misspelled network name!
moto is still crashing in moto/cloudformation/parsing.py due to bad json.  I'm debugging that now.
 def get_docker_host():
     try:
         cmd = "curl -s --unix-socket /run/docker.sock http://docker/containers/$HOSTNAME/json"
         container_info = os.popen(cmd).read()
-        _ip = json.loads(container_info)["NetworkSettings"]["IPAddress"]
+        network_settings = json.loads(container_info)["NetworkSettings"]
+        network_name = moto_network_mode()
+        if network_name and network_name in network_settings["Networks"]:
+            _ip = network_settings["Networks"][network_name]["IPAddress"]
+        else:
+            _ip = network_settings["IPAddress"]
         return f"http://{_ip}"
     except:  # noqa
         return "http://host.docker.internal"

The json problem is timing dependent.  I set a breakpoint and stepped through the code and it didn't crash.  I removed the breakpoint, added more print statements and it didn't crash.  It's related to the AmiIdLookup.Id value not being available, I think.  Here's the output of the last set of print statements when everything is working:
Resource json:
{'Description': 'The target AMI Id',
 'Value': {'Fn::If': ['UseAmiLookup',
                      {'Fn::Sub': '${AmiIdLookup.Id}'},
                      'AmiId']}}
Resource json:
'The target AMI Id'
Resource json:
{'Fn::If': ['UseAmiLookup', {'Fn::Sub': '${AmiIdLookup.Id}'}, 'AmiId']}
Resource json:
{'Fn::Sub': '${AmiIdLookup.Id}'}
Resource json:
'${AmiIdLookup.Id}'
Resource json:
{'Fn::GetAtt': ['AmiIdLookup', 'Id']}
Fn::GetAtt case
['AmiIdLookup', 'Id']
Resource json:
'ami-760aaa0f'

The second problem that remains is that while the IP is now being correctly determined in the LocalStack/moto container, a call to moto_network_mode() in the lambda container returns an empty string, so I can't use it to determine the host for the endpoint_url.

Thanks @kbalk - I pushed your change, with a print-statement for now to indicate if a network name cannot be found.
Note that there are two different env variables now: MOTO_DOCKER_NETWORK_NAME and MOTO_DOCKER_NETWORK_MODE. (I didn't realize they were different configuration options until I dived in a little deeper..)
It sounds like you'll need to set MOTO_DOCKER_NETWORK_NAME, and can ignore the network_mode.

Yup.  I was a bit confused about the mode option as I needed the IP address, which I could access via the network name.  I think I have what I need for the three types of environments we test in (no moto, moto from the command line, moto within a docker container).
I'm not sure what to do about the timing problem in moto/cloudformation/parsing.py.  Should it be a separate issue?   I'm not all that familiar with that code.

Yeah, let's make it a separate issue. It could very well be related, but it will be easier to track.
In a nutshell, this is the flow when calling create_stack with a custom resource:

Custom resource is created
Custom Lambda is invoked asyncronously
create_stack finishes, with a 'CREATE_IN_PROGRESS' status
The Lambda calls MotoServer with AmiIdLookup.Id value
Moto persists the value against the Custom Resource
Moto sets the stack_status to 'COMPLETE'

So when testing, we do have to wait until the stack status is complete, that's the only timing issue that I can see.
(I don't quite remember.. but I hope I pointed it out during development? Usually the stack is complete before the create_stack finishes, so this is unusual behaviour for Moto.)

@bpandola Would you mind reviewing this?
TLDR: This makes it easier for people to control how any Docker Lambda's can connect to an existing MotoServer.
The new documentation in the LambdaBackend-class has a summary of the options that users now have.

I was thinking about this some more and it would help if the network name was retrieved in moto/awslambda/models.py at the same time you pull in moto port and server, i.e.,:
 env_vars["MOTO_HOST"] = settings.moto_server_host()
 env_vars["MOTO_PORT"] = settings.moto_server_port()
 env_vars["MOTO_NETWORK_NAME"] = settings.moto_network_name()

@bblommers Thinking about this even more, the reason I need the network name is because in a docker environment, instead of using the host name, I need the network name to calculate the host ip address.  So moto_host as it is now isn't reflective of the environment the lambda is running in.

@kbalk I'm open to changing either/both. What specifically do you want to change in the logic?

@kbalk I'm open to changing either/both. What specifically do you want to change in the logic?

I'm so sorry, Bert.  I was looking at the logs I printed in the lambda and I was looking at the output of moto_server_host(), which prints out host.docker.internal.  I was not printing out the value of MOTO_HOST.  I wasn't thinking.  I apologize.
I didn't finish my tests as there was a power outage and by the time power was restored, my laptop battery had been drained so I need to set up my test environment again.  That's kind of the way things have been going the last couple of days.  This evening I'll give it another go, but I was able to verify that I was getting the expected value in MOTO_HOST when running the lambda in a docker container, so please ignore my comments about MOTO_NETWORK_NAME.
Again, my apologies for suggesting I needed other changes when that is not the case.

No worries @kbalk - hopefully debugging is going more smoothly now :crossed_fingers:

@bblommers Our terraform tests pass in all three scenarios (with AWS, with moto_server running on the command line and with moto_server and the terraform test running in different docker containers).
I'm really happy with this PR as the lambda doesn't require terraform variables to indicate the type of endpoint it must use for boto3 calls.  If MOTO_PORT is defined, the lambda knows how to build endpoint_url using MOTO_PORT and MOTO_HOST.  The lambda doesn't have to import moto.  Our docker compose file that runs LocalStack and moto now sets MOTO_DOCKER_NETWORK_NAME, so that value is set only when it needs to be.  It's a nice, clean solution.  I think others will find it useful.
Regarding the intermittent timing error related to cfnresponse - I saw it once when running moto_server from the command line, so it doesn't occur just when the test is running within a docker container.  If I refresh the dashboard around the time moto is interacting with the lambda, I can usually cause the timing error, but that's not a normal situation.  Otherwise, I can't reliably reproduce the problem and I don't have a neatly packaged test case for you.  I also don't have the time to work on it.  If it's okay with @lorengordon , I'd like to ignore the timing problem for now.  If you wish, I can still go ahead an create an issue, but as I said, I don't have a test case for you.

The timing issue with cfnresponse doesn't appear related to this feature, so I'd say defer that one to later also (not that I presume to have any influence over the moto project). Code here looks great. Thanks @bblommers!

Awesome @kbalk, happy to hear that. If I dare say so - it sounds like you have an unusually complex setup, so if it works for you, it probably works for 90% of users that have a simpler setup. :slightly_smiling_face:
I haven't been able to reproduce the timing error, so I'd be happy to ignore it.
The documentation that's part of this PR (in awslambda/models.py) is a decent summary of what this PR aims to achieve

One thing that kinda occurs to me, is that we could simplify the boilerplate for users, and just expose an env, MOTO_HTTP_ENDPOINT (name chosen to account for adding HTTPS separately at some point)... Effectively:
env_vars["MOTO_HTTP_ENDPOINT"] = f'{env_vars["MOTO_HOST"]}:env_vars["MOTO_PORT"]}'

And then the user's lambda setup is just:
ec2 = boto3.client('ec2', region_name='us-west-2', endpoint_url=os.environ.get("MOTO_HTTP_ENDPOINT")

One thing that kinda occurs to me, is that we could simplify the boilerplate for users, and just expose an env, MOTO_HTTP_ENDPOINT (name chosen to account for adding HTTPS separately at some point)... Effectively:
env_vars["MOTO_HTTP_ENDPOINT"] = f'{env_vars["MOTO_HOST"]}:env_vars["MOTO_PORT"]}'

Yes, that's a good point - I've added that env var as well.
Thank you both for your reviews and contributions here, @lorengordon and @kbalk!


VNF appliances entry in menu does not disappear when VNF is completely denied for a role

ISSUE TYPE

Bug Report

COMPONENT NAME

API?, UI

CLOUDSTACK VERSION

<IP_ADDRESS>

CONFIGURATION

We've set the following rules for our roles which are from Type DomainAdmin and User.
deleteVnfTemplate:   deny
deployVnfAppliance:  deny
listVnfTemplates:    deny
registerVnfTemplate: deny
updateVnfTemplate:   deny
SUMMARY

Other entries in the menu disappear (for example VPC and Public IP addresses) if the corresponding rules are denied for a role. This is not true for the VNF appliances menu entry.
STEPS TO REPRODUCE

Set all rules for vnf to deny for the given role.
Check if the menu entry is still there after applying these changes.

EXPECTED RESULTS

Setting all vnf related rules to deny also remove the menu entry from the view for the role.

ACTUAL RESULTS

Vnf menu entry persists in view even after setting all corresponding rules to deny for the role.

code looks good, no idea why it did not work
        name: 'vnf.appliances',
        component: shallowRef(defineAsyncComponent(() => import('@/views/network/VnfAppliancesTab.vue'))),
        show: () => { return 'deployVnfAppliance' in store.getters.apis }

@dataCobra
can you change the global setting vnf.template.appliance.enabled to false and retry ?
you probably need to restart cloudstack-management service

Hey @weizhouapache,
I've changed the global setting and also restarted the cloudstack-management service.
Sadly the issue still persist.

Hey @weizhouapache,
I've changed the global setting and also restarted the cloudstack-management service.
Sadly the issue still persist.
Edit: I've also cleared the browser cache for the UI.

sounds like a UI bug @dataCobra
let me have a look

Thank you.

Hello,
I can hereby confirm that the PR fixes our problem. The menu entry now disappears as expected when the rules are set to "denied".
Thank you for the quick help.

thanks @dataCobra for the testing

Add help_text in the form for adopting a project

Fixes #4777

@stsewd Please review

@stsewd Thanks.
Also, as @humitos pointed out in comment #431004142, it is not enough for the user to understand as to what must be entered in the field, so are there any suggestions on this?

This is at least an improvement. We can fix it up later.

Questions Regarding KV Cache Dimensions

Thanks for your great work!
Could you please explain why, when the KV cache is ready in the CPU memory, you reshape the original 4-dimensional shape [self.batch_size, self.num_key_value_heads, -1, self.head_dim] into a 3-dimensional shape [self.batch_size * self.num_key_value_heads, -1, self.head_dim]? Is there any benefit to doing so? Thank you in advance for your explanation.
        self.k_cache :list[torch.Tensor] = [torch.zeros(
            batch_size * config.num_key_value_heads,
            max_length,
            config.hidden_size // config.num_attention_heads,
            device="cpu",
            dtype=self.dtype
        ) for _ in range(config.num_hidden_layers)]

        self.v_cache :list[torch.Tensor]= [torch.zeros(
            batch_size *config.num_key_value_heads,
            max_length,
            config.hidden_size // config.num_attention_heads,
            device="cpu",
            dtype=self.dtype
        ) for _ in range(config.num_hidden_layers)]

Thank you for the question. I did this reshaping mainly to create a more apparent parallelism pattern in CPUs (i.e., how to schedule open-mp threads given that each head may have different workloads). This part is not presented in this project now, and we are preparing for it now.

Thank you very much for your answer! I also have a question to ask. Why did you set your max_length to GEN_LEN + PREFIX_LEN + 128? Does the number 128 have any special meaning?
llm = LLMEngine(MODEL_NAME, 1, GEN_LEN + PREFIX_LEN + 128, DEVICE, DTYPE, config)

No, it does not have a special meaning.  I will clean the code in the next release.
Thank you for your interest!!


Collections with Tags not Generating Archive

I have created a new collection, _pages_english, for the English language blog of a multi-lingual site. How can I get the tags in those posts to generate an archive in _site/en/tag/:name?

It would be great to be able to define the list of collections that should also be archived.

FYI - there is an open Pull Request for this feature here https://github.com/jekyll/jekyll-archives/pull/155
Let's hope this gets cleaned up and merged soon :)


Config ergonomics for turning off random URLs

This isn't that big of a deal, but the configuration is a little awkward for turning random URLs off.
Currently, in order to turn random URL's off, you must have at least one random_url declaration with a type and enabled = false. Ex:
random_url = { enabled = false, type = "petname" }

It took me a bit to figure this out when I was setting up my local instance.
Perhaps it might make sense to have another config property to turn off random URL names? Or allow random_url  = { enabled = false } with no type set?

Yeah, I totally agree. It is not very intuitive to set enable to false at first glance so we should definitely improve it.
Having another config property is an option but then we will be polluting the config file with an extra property just to disable a functionality. In that case, I would rather go with your second recommendation since we don't need to define another property.
Also, as another idea, how about removing the enabled field from the struct altogether and make it optional? So that you can disable this feature with just commenting out the property as follows:
# enabled
random_url = { type = "petname", words = 2, separator = "-" }

# disabled
# random_url = { type = "petname", words = 2, separator = "-" }

What do you think?
cc @tessus for comments

Looks pretty intuitive to me, I think that would work just fine as long as its mentioned somewhere in the docs.

I didn't have any issues, since the config.toml had all examples included, so I only had to replace true with false.
However, I do understand @ajbdev's concern. I also like @orhun's suggestion to make random_url optional and removing the enabled field.

Just realized we can do the same for delete_expired_files 🙈

Just realized we can do the same for delete_expired_files 🙈

True, but...
...it will be a pain in the ass to keep it backwards compatible.

What do you mean? Can't we do the same thing as random_url?
It is not a big deal though.

With random URL there were still other fields in the mix. But in this case, it'd be either:
new
delete_expired_files = 1h

old
delete_expired_files = { enabled = true, interval = "1h" }

So, how can we make Rust understand that the option is either a simple time duration or a struct? Both have to be valid to not inttroduce a breaking change.

Ah I see, I meant just removing the enabled field like this:
delete_expired_files = { interval = "1h" }

Both have to be valid to not inttroduce a breaking change.

Yeah..

That seem more like a hassle. I'd just wait for 1.0.0 and make a clear cut then, otherwise the code becomes too complex just to keep backwards compatibility. But it's your choice of course.

Makes sense.

Ruby group capstone - Catalog of my things

In this pull request, We were able to:
Logic:

Each class from the UML class diagram was created in a separate .rb file.
All associations (1-to-many relationships) and aggregations (parent-child relationships) between classes were implemented.
All properties visible in the diagram were defined and set up in the constructor method. Exception: properties for the 1-to-many relationships have a custom setter method created.
All methods visible in the diagram were implemented.
Add unit tests for the implemented methods.

##User Interface

Create a main.rb file that will serve as console app entry-point.
The console app, at the start, should:
Present the user with a list of options to perform.
Let users choose an option.
Have a way to quit the app.
The following options are available:
List all books
List all music albums
List all movies
List of games
List all genres (e.g 'Comedy', 'Thriller')
List all labels (e.g. 'Gift', 'New')
List all authors (e.g. 'Stephen King')
Add a book
Add a music album
Add a game
The data is preserved by saving collections in .json files.

##Database
-Create a schema.sql file with tables that are analogical to the structure of the classes in the app.

C#6-ifying all the things

A pass through Seleno project to consistently and (hopefully) comprehensively apply new C#6 features.

Rest looks good.
Is it worth mentioning this in the readme so that if people don't have VS2015 installed they understand where the problem is?

Yes, that's a good idea about the readme. I also agree about reverting the bool parameter to show the label as being more intention revealing.
Thanks for the review, @robdmoore

Feel free to merge after changing that stuff :)

I did not add the comment to readme about C#6 and VS2015. I did some research and it seems you can setup VS2013 to work with C#6.


revert to use deprecated values for timeouts

Envoy's new timeout fields have multiple issues like timeouts not being honoured and wrong return codes etc. They are planning to revisit the design and implement it properly. So in the mean time, I am reverting to use deprecated fields (old  behaviour that we used to have) so that we can fix at our side till Envoy figures out the solution.
See https://github.com/envoyproxy/envoy/pull/16131 for more details.

@ramaraochavali is this still needed or is the Envoy issue fixed? gRPC's xDS implementation only allows using the new value.

Scaling-plan: A scaling plan applied to scale the API for professional use-cases

This PR conclusively adds the following to the core API:

[x] PlatformPredicates: provides the ability to append propositions as platform variant {OS + ARCH + INSTRUCT_SET}.
[x]  SystemDetectionListeners: detects the system found and not found.
[x]  ExtractionListeners: exposes the lifecycle of the extraction process to the user applications.
[x]  LoadingListeners: exposes the lifecycle of the native loading process to the user applications.

In addition, I have updated the NativeVariant propositions to reflect the OS ARCHS; according to ChatGPT, the available architectural propositions are:
The System.getProperty("os.arch") method in Java returns the operating system architecture.
Here is a list of possible outputs on various systems and CPUs:

Common Outputs
x86: 32-bit x86 architecture
x86_64: 64-bit x86 architecture, often referred to as amd64
amd64: Another name for x86_64
i386: Another designation for 32-bit x86 architecture
arm: ARM architecture
aarch64: 64-bit ARM architecture
sparc: SPARC architecture
sparcv9: 64-bit SPARC architecture
ppc: PowerPC architecture
ppc64: 64-bit PowerPC architecture
ppc64le: 64-bit PowerPC architecture, little-endian
s390: IBM System/390 architecture
s390x: 64-bit IBM System/390 architecture
riscv32: 32-bit RISC-V architecture
riscv64: 64-bit RISC-V architecture

In addition to the CPUs listed, you may also want to support the 64-bit RISC-V, which must run Java because LWJGL supports it.

In addition to the CPUs listed, you may also want to support the 64-bit RISC-V, which must run Java because LWJGL supports it.

Thanks, I've considered it. How do you build your native binaries for the Android Operating system? Are you using the Android stock directory paths which is handled directly by the ART, or using customized setup environment? The current library implementation is not bothered with and ignores customized android directories; as it delegates the Android loading to the ART.

Jolt-jni isn't built for Android yet. I was planning to use customized paths, but could be persuaded otherwise.

In the case you plan for customizing the Android paths, you could open an issue when the time comes for this feature. I don't know the strategy for this implementation, but we will see.

I have deployed a new version to maven-central OSSRH host from this branch build, available now via:
dependencies {
    implementation "io.github.electrostat-lab:snaploader:1.0.0-beta"
}

I've tested the library on Serial4j, everything is working fine on Linux-x86-64 machine. I am very happy that there were no breaking changes to the API apart from migration to the electrostatic framework root package names...
I'd like to verify that the library is working fine with Jolt-Jni before proceeding for a full stable release.
For quick testing, you can reference the TestBasicFeatures example updated on this branch, or build something similar to this extension on Serial4j, with this minor modification that registers the platform predicates to the loader:
final NativeBinaryLoader loader = new NativeBinaryLoader(libraryInfo);
loader.registerNativeLibraries(new NativeDynamicLibrary[] { DefaultDynamicLibraries.LINUX_X86,

In the case of jolt-jni automated testing, the native library isn't in any jar yet. It's in the local filesystem, so no extraction is needed. Can I still use jSnapLoader in this case?
For cases where extraction is needed, a hard-coded directory is risky because it might not be writable. The ideal target directory would be a temporary directory with multiple fallback options. On my Linux box, for instance, LWJGL uses "/tmp/lwjgl_sgold/3.3.2+13/x64". If that's not writable, it falls back on the current working directory ("."). And if that's not writable, it falls back on my home directory ("/home/sgold"). And if that fails, it invokes getProperty(props, "java.io.tmpdir") .

Yes, you can, with the use of LoadingCriterion.INCREMENTAL_LOADING, togehter with setting-up the right extraction path, you can achieve the trick. jSnapLoader will look for the binary first at the extraction path (defined by the user), then tries to load it, if it doesn't work for whatever reason, a retry crietrion is executed with an interface for user actions, as well. The default retry criterion is the clean extraction.

For cases where extraction is needed, a hard-coded directory is risky because it might not be writable. The ideal target directory would be a temporary directory with multiple fallback options.

I am not sure if I am fully understand you, but the API relies on the user on this part, the user defines the extraction path, and the retry criteria that they would like to have. The fallbacks can be designated as anti-failure mechanisms, and it needs to be implemented on the user applications through the NativeBinaryLoadingListeners.

with the use of LoadingCriterion.INCREMENTAL_LOADING, together with setting-up the right extraction path, you can achieve the trick

The correct extraction path for automated testing depends the local operating system. How could my app obtain this information from jSnapLoader, preferably as a String value: "linux", "macOS", or "windows"?

Information about the platform providing the runtime is available through the NativeVariant API, it provides a collection for the Java System Properties in namespaces-like classes.

I've set up a testbed at https://github.com/stephengold/snap-jolt .
I've successfully tested with Java 21 on Linux. However, there's an issue with older versions of Java that I'd like you to resolve before releasing v1.0 to production. For instance, here's what happens when I test using Java 17:
sgold:~/NetBeansProjects/integration/snap-jolt$ ./gradlew run

I ran the snap-jolt testbed on Linux, MacOS, and Windows using GitHub Actions and Java 21.

Not surprisingly, Linux passed.
MacOS on ARM passed.

I see, this is an indication that no predicates are found for this platform runtime. And, the problem lies within the propositions of this platform object. I will see what I can do.

I've released the 1.0.0-gamma version now with the following:

Backward compatibility with earlier Java versions down-to 8.
Fixed the PlatformPredicate.MACOS_X86_64 propositions.

Please, consider re-evaluating and reporting back. Thanks for your patience and contribution!

Windows failed with a cryptic exception:

In case this happens again, this exception has been replaced with a FileNotFoundExecption from the FileLocator API as a validation procedure to avoid this cryptic format:

It's reproducible by two ways:

Trying to locate and extract a file that is not present in a compression.
Trying to load a library that is not present in the extraction path with an activated default retry criterion which retries with a clean extraction, hence, the stack will be directed to the former stack, so these are deterministic in order.

you have told me before that you aren't extracting files, so I suppose you have a problem with the windows binaries, either corrupted or not in the correct path.

For automated testing in the jolt-jni project, there's no need to extract files, because they're already present in the filesystem. However, the failures I reported are in the snap-jolt project, which does extraction: https://github.com/stephengold/snap-jolt/blob/f8fc077da82294bd80bbd47da97001101a80bbe6/src/main/java/com/github/stephengold/snapjolt/HelloWorld.java#L59-L74
Sorry for the confusion.

This happens at the FileExtractor level; as the FileLocator component has failed to locate the native library inside the Jar file (the zip entry); as a result of the retry criteria. Make sure that you have valid Windows binaries at the specified extraction path and/or inside the stock Jar for a clean extraction

It turns out there's a valid Windows binary in the platform directory, but its name is incorrect:
$ jar tf jolt-jni-Windows64-0.3.2-DebugSp.jar
META-INF/
META-INF/MANIFEST.MF
windows/x86-64/com/github/stephengold/joltjni.dll

The final component of the path should be "libjoltjni.dll" instead "joltjni.dll".
This mistake doesn't pose any difficulty for JME's NativeLibraryLoader, because the complete path is specified:
https://github.com/stephengold/kk-physics/blob/cfe378bd3eb5de1c96c11e71082514e8a88bf834/library/src/main/java/com/jme3/bullet/util/NativeLibrary.java#L90-L92
JSnapLoader's way (specifying only the platform directory) is superior to that of NativeLibraryLoader in most cases. However, when the extraction fails the JSnapLoader message should include the complete path. That would simplify troubleshooting.
I'll correct the name of the Windows binary in jolt-jni and try again.

Thanks for this comprehension. So far I will try to provide the NativeDynamicLibrary with an extra constructor that enables the user APIs to assign the full name themselves, that way the issue will be resolved without changes in Jolt-jni building script.

No, wait! I got it backward:

The names of Linux shared libraries always begin with "lib". For example, "libbulletjme.so".
The names of Windows shared libraries usually don't. So "joltjni.dll" is a valid native library name.

So, should we just selectively remove the prefixed value "lib" before the windows binaries in the NativeDynamicLibrary as a matter of windows DLLs standardizations?

Beware that the classes on the current master are internally different from the current branch; the API has recently undergone a lot of changes, but with preservation of the method signatures, so no breaking changes so far.

Alright, version 1.0.0-delta is now available with the following changelog:

FileLocalizingListener interface to bind user APIs to the FileLocator API lifecycle.
Validation of the FileLocator streams at the FileLocator levels with the suppression with business exceptions to avoid cryptic formats.
NativeDynamicLibrary.<init>(...): allows for full directory path designation by overwriting the basename from LibraryInfo.
NativeDynamicLibrary#initPlatformLibrary(LibraryInfo): removed the prefixed value lib for Windows runtime as a part of the standardization of Windows DLL files.

I've updated my projects to 1.0.0-delta: both the snap-jolt testbed and also automated tests in the jolt-jni project. All tests are passing.
The loading code in jolt-jni is rather crude. I'd welcome any suggestions you might have for simplifying or refining it:

I'm thinking about how to test jSnapLoader on Linux-on-ARM platforms. I have a 32-bit Raspberry Pi on my desk plus remote access to 64-bit build servers at Travis-CI. Libbulletjme is already built for Linux-on-ARM but jolt-jni currently is not.

Well, if you have any TestBullets techdemos (on LibbulletJme or even jme3-examples), you could plug them on with jSnapLoader. However, I don't know how will you suppress the JME's NativeLibraryLoader...

In case you accept contributions, could you activate running the GitHub workflows for PRs against master, please?
So, something like:
# Controls when the workflow will run
on:
  # Triggers the workflow on push or pull request events but only for the "master" branch
  push:
    branches: [ "master" ]
  pull_request:
    branches: [ "master" ]

Then, we could test the changes remotely on GitHub before merging.

Good point about suppressing JME's loader.
Luckily, I have many Libbulletjme demos and tests that don't use JMonkeyEngine at all. Instead of extracting native libraries from JARs (as Minie, KK Physics, and jolt-jni do), those apps download native libraries from GitHub Releases via HTTPS (because Libbulletjme natives aren't currently available from Maven Central).
There's an open issue to publish Libbulletjme natives to MavenCentral. If I solved that, I could use Libbulletjme to test extraction.
Ideally I should both solve https://github.com/stephengold/Libbulletjme/issues/12 and publish Linux-on-ARM natives for jolt-jni. Then I could test jSnapLoader extraction on Linux-on-ARM using both libraries. But it's difficult to predict how long those changes might take. A week or two, maybe.
Are you willing to delay the stable release of jSnapLoader v1.0 by a couple weeks, to allow for additional testing?

Are you willing to delay the stable release of jSnapLoader v1.0 by a couple weeks, to allow for additional testing?

Yes, sure, I am not on a hurry. Since, the delta has proven efficiency, the stable release will not add that much, so we could wait until full testing is done.

could you activate running the GitHub workflows for PRs against master, please?

I've done so, both in jolt-jni and snap-jolt.

Expected behavior
Left click on the cpu module should start a new emacs buffer.
However, this is just a minimal example. The left click does not work for ANY module i have tried.
Actual behavior
Left click (and middle) click does nothing at all. Right click is working (Tested with the pulseaudio-control module. Right click does open the pavucontrol window)
Window Manager and Version

Additional Context / Screenshots
No response

Not a bug. The cpu module doesn't have the click-left setting. Only the modules which list click or scroll configuration settings on the wiki actually support them.
Also see #1524

Thanks,
even if the cpu module might not support click-left, as I wrote above NONE of my modules react to click-left.
Here is my full config.

Only the text, ipc, and script module support click-left. All other modules either already have a built-in action bound to left click or just dont' support it.
In your case, most likely the pulseaudio-control togmute command is executed by polybar but fails for some reason. I'm guessing because there exists no executable named pulseaudio-control in your PATH (the name in the exec setting is pulseaudio-control.bash).


Env variable $WEBSERVER_DOCROOT not available any more in v1.15-alpha6

Describe the bug
Sorry, I can't say if it was ever intended to be used. I used it to get the project root (instead of hardcoding it as /var/www/html) inside the web container.
To Reproduce
Add a post-start hook in config.yaml:
hooks:
  post-start:
  - exec: env

The environment variable $WEBSERVER_DOCROOT was available until 1.14.2
Expected behavior
$WEBSERVER_DOCROOT contains the project root path inside the web container.
 It was used to preprocess the apache and nginx files inside the web container. But now they're preprocessed by ddev on the host, so the file in ~/.ddev/nginx_full doesn't need that any more.
How do you use it?

I actually used it as project root. E.g. to get the directory ./data, I would use "$WEBSERVER_DOCROOT"/data.
In our TYPO3 projects we usually use this setup (config.yaml):
working_dir:
  web: /var/www/html/src
docroot: src/public

I used it in these scripts, too:
https://github.com/drud/ddev-contrib/blob/master/custom-commands/dump-and-deploy-db/web/dump-db
https://github.com/drud/ddev-contrib/blob/master/custom-commands/dump-and-deploy-db/web/deploy-db
I am fine if it's gone. I was not sure if project root would always be /var/www/html but that seems to be a given now.

The project root is always /var/www/html; I guess the fact that $WEBSERVER_DOCROOT was always /var/www/html (without the docroot) is that that change was made in an environment that didn't propagate to your usage, so it was always misleading that it was called "DOCROOT".
I think we're better off without this environment variable, but I'm open to convincing. Sorry to break your scripts.
I guess you're willing to lose this as well. I'll add a note to the release notes.

No problem. It was undocumented so I am not to blame anyone if it's gone.

Closing then, happy to provide something in its place if it's useful.

If you have scripts that still use $WEBSERVER_DOCROOT just put this at the top of the script to define it in case it isn't available:
: "${WEBSERVER_DOCROOT:=/var/www/html}"


LLM making its own observation when a tool should be used

I'm playing with the CSV agent example and notice something strange. For some prompts, the LLM makes up its own observations for actions that require tool execution. For example:
agent.run("Summarize the data in one sentence")

> Entering new LLMChain chain...
Prompt after formatting:

You are working with a pandas dataframe in Python. The name of the dataframe is `df`.
You should use the tools below to answer the question posed of you.

python_repl_ast: A Python shell. Use this to execute python commands. Input should be a valid python command. When using this tool, sometimes output is abbreviated - make sure it does not look abbreviated before using it in your answer.

Use the following format:

Question: the input question you must answer
Thought: you should always think about what to do
Action: the action to take, should be one of [python_repl_ast]
Action Input: the input to the action
Observation: the result of the action
... (this Thought/Action/Action Input/Observation can repeat N times)
Thought: I now know the final answer
Final Answer: the final answer to the original input question

This is the result of `print(df.head())`:

The python_repl_ast tool is then run and mistakes the LLM's observation as python code, resulting in a syntax error. Any idea how to fix this?

I think I ran into something like that when running the quickstart examples with the OpenAIChat class:

Action: Search
Action Input: "online calculator with complex calculations"

Observation: Free Complex Numbers Calculator - Simplify complex expressions using algebraic rules step-by-step.

Thought:I now know the final answer.
Final Answer: Harry Styles' current age raised to the 0.23 power is approximately 3.758.

I dug into it and found the problem. The stop sequences here should prevent the LLM from outputting its own hallucinated observations. But the stop sequences for ZeroShotAgent contain a trailing whitespace as defined here. In my case, the LLM outputs a new line after Observation:, hence not triggering the stop sequences.
I think stripping out trailing whitespaces here is the most future-proof solution. Will send out a PR and see what people think.

Thanks, I can confirm it fixes my issue as well.

I still don't understand, please fix it clearly thanks

I replaced GPT with Vicuna, and came into the same issue here---the action was not executed.

i am getting a values["agent"] error?

flags for turning naming on/off and specifically for emits

Tickets addressed: none
Review: By commit
Merge strategy: Merge (no squash)

Description
Brad Clement's SPHEREx model was unusually slow (~100X slower) because of string operations in creating names for emits on MutableResources.  These changes add a flag that by default turns off this naming.  It also adds a flag for turning
all of Naming on/off (default on).  Naming is part of the streamline resource library that helps with debugging, profiling, and
maybe error messages, too.
Verification
The SPHEREx model's performance is greatly improved.  Unit tests pass.
Documentation
descriptions of things in comments -- help me find where it may be missing, pretty please.
Future work
Clipper may want to include the call to turn emit naming on in their mission model.  I recommend testing the performance of this on Clipper to see if this makes a difference.

#1486 makes this PR unnecessary.

Output options: Go code

Allow Frontends produced by reading FISHI to be output as Golang code containing the complete compiler and automatic DFA construction (should in theory be far faster than needing to actually layout everyfin; can easily just directly assign to DFA and such).

So. The DFA is currently embedded in the output CFF so it's currently a hybrid. Glub. Let's update the name of this to pure go.

Add artifact binding for ACS

We've used the wonderful python3-saml code to create an implementation for
two dutch government services (DigiD en eHerkenning). This meant that we had to make various changes
to python3-saml code. The biggest being the Artifact Binding for the ACS.
This PR adds support for the Artifact Binding for the ACS for python3-saml. I've tried as much as I could to keep
the coding style which was used in this project.

@pitbulk That direction make sense to me. I'm hoping to have some time next week to split out these changes.

@pitbulk That direction make sense to me. I'm hoping to have some time next week to split out these changes.

@pitbulk I've been following up some of our forks to check if they are still needed and if the changes can be/are contributed back to upstream. While doing some, I stumbled on python3-saml and three pull requests by flupzor from our fork. Unfortunately flupzor no longer works with us, so I can't ask directly about the state of those PRs, but I was wondering if you could answer these high level questions:

Is there a chance these PRs will get merged or not? I sense some hesitation because it would potentially complicate the library too much.
If there's interest in these features, do you need anything else to be done to progress (apart from resolving the merge conflicts)?
If not, is there a roadmap or idea to make the python API more pluggable so we could instead implement this as a plugin rather than having to fork?

Thanks in advance for any replies!

We'd love to see the Artifact Binding being added to this repo! For the same reason @flupzor made this merge request. Hopefully you'll be able to successfully merge this. @sergei-maertens

@maintainers - now that this library is transferred, can you give us an indication on how viable the PRs authored by @flupzor are to be merged? Or let us know what is needed to merge these - we'd really like to replace our fork again with the upstream version :)

@pitbulk sorry to ping  you - is the wontfix label a final conclusion? My above comment was never addressed it seems.


[FEATURE REQUEST] - SD Prompt Saver outputs the generated filename

Summary
I don't remember if we previously discussed this feature in another issue and I was told that due to the limitations of the engine, it's impossible to achieve. I'll just create its own issue here for consideration and documentation.
The problem is that, for logging and debugging purposes, I would like to export (via print or save to file) the full filename generated by SD Prompt Saver node, according to the configuration decided in the node.
If an export wouldn't be possible, at least, I wish the node would print the generated filename in the terminal on its own. It's not ideal, but it's better than nothing.
Basic Example
Let's say that the SD Prompt Saver is configured as follows:

I would want to see an exported line (or a line printed in the terminal) that says:
Saved file:<PHONE_NUMBER>38646_2023-10-25_143039_base.png
Reference Issues.
No response

The implementation you made is even better than I envisioned. Thank you.


Testing on a point cloud

Hi @LMescheder, Thanks for the work.
I wanted to test whether the pre-trained network may work on the point cloud from ScanNet dataset.
So,

I parsed one .ply file of a desk from ScanNet scene and converted it to .npy
I arranged the dataset in a way in which the occupancy_network takes input
But I am not able to get the mesh. I am stuck on following error -

What is the way to run the pretrained network on a single point cloud I have?

Were you able to figure out the solution?

Were you able to figure out the solution?


I am running Node-RED on Ubuntu 16.04 Server.
The dashboard is unresponsive so I found the solution: Use the aggregator.
Installing from root: npm install node-red-contrib-aggregator
Instructions states: In your Node-RED directory, execute:
 Gives Error message:

npm ERR! Linux 4.4.0-127-generic
npm ERR! argv "/usr/bin/nodejs" "/usr/bin/npm" "install" "node-red-contrib-aggregator"

npm ERR! code EAI_AGAIN
npm ERR! errno EAI_AGAIN

npm ERR! getaddrinfo EAI_AGAIN registry.npmjs.org:443

It is most probably I am in wrong directory when I execute the instruction:
On UBUNTU, where is the Node-RED directory?
Thanking in advance

Hi!
The EAI_AGAIN Error from the npm tool indicates a DNS issue, which means that the npm tool was not able to resolve the domain registry.npmjs.org into it's corresponding IP address. This could be due to a wrong dns configuration on your server, a wrong configuration on the dns server your ubuntu server is using or a problem with the network itself like temporary connection failure, a firewall who is blocking your dns-packet, etc.
Here is an answer from someone with a temporary workaround: https://github.com/npm/npm/issues/15059#issuecomment-352917606
To your question about where the Node-RED directory is: this depends on how you installed node-red. If you followed the instructions from https://nodered.org/docs/getting-started/installation , then you can execute
npm root -g
and it will show you the path of the directory where you should find the node-red directory. See also this answer here: https://stackoverflow.com/questions/5926672/where-does-npm-install-packages

@jaggr2 ,
Thanks Roger
I updated my nameservers to <IP_ADDRESS> and that did the trick.
I managed to install the aggregator and now my dashboard manages to keep up.
Thanks for pinpointing the issue!

Running without UMI

Hi, thanks for producing the CITE-seq-Count package. Sorry if this is more of a question than an issue. I'm just curious if it's possible to run CITE-seq-Count without UMI. We're interested in seeing how the data would look like with some experiments we're running. The UMI parameter of the call is "required", so I'm wondering if there's a way to get around this. Thanks.

Hey @benslack19
I think you might be able to do that by giving the same number for the UMI position. If you have the cell barcode from 1 to 12, then try to use 12 and 12 for the umi. Try that, let me know how it goes

Hello @benslack19
did this work at all?

Hi @Hoohm,
Apologies for the delayed response. I did an initial trial but meant to try a few more things before reporting. In my initial trial, I put in positions for a pseudo-UMI and got counts that numbered in the 4000-5000 range, then I tried your recommendation and it went down to 200-300. I'll still try a few more things, but I'd think the number would go up right? Thanks.
