Analyze this terraform incident and provide diagnosis and fix:

```
I am trying to set up my DNS zones and records with in those zones and I can't get the structured collection I am looking for to pass into the tf file that will generate all the zones and records. I have a list of DNS objects and each object will have multiple lists of record objects. I am trying to create lists of just records (a, cname, txt, ...). Im trying merges and flattening and I just not sure how to get what I need. I keep trying different patterns with merge and flatten but keep getting errors in different configurations.
Errors:
`Error: Invalid 'for' expression. Extra characters after the end of the 'for' expression.
Error: Missing attribute value. Expected an attribute value, introduced by an equals sign ("=").
Error: Invalid 'for' expression. Key expression is required when building an object.
Error: Missing key/value separator. Expected an equals sign ("=") to mark the beginning of the attribute value.
`
```
Variable Definition:
```
`variable "dns_target_child_zones" {
 type = list(object({
 name = string
 a_records = list(object({
 name = string
 ttl = number
 ip_address = string
 }))
 cname_records = list(object({
 name = string
 ttl = number
 record = string
 }))
 mx_records = list(object({
 name = string
 ttl = number
 record = list(object({
 preference = number
 exchange = string
 }))
 }))
 txt_records = list(object({
 name = string
 ttl = number
 record = list(object({
 value = string
 }))
 }))
 }))
}
`
```
Locals file:
```
`locals {
 a_records = flatten ([
```

[Assistant]
Here's an example of the local object you could create for a_records (note: I included the ip_address attribute but you have records which doesn't appear in the a_records variable object):
```
` a_records = flatten([
 for v in var.dns_target_child_zones : [
 for record in v.a_records : {
 name = record.name
 zone_name = v.name
 ttl = record.ttl
 ip_address = record.ip_address
 }
 ]
 ])
`
```
This will product an output like the following:
```
` + a_records = [
 + {
 + ip_address = "ip1"
 + name = "a1"
 + ttl = 10
 + zone_name = "dns1"
 },
 + {
 + ip_address = "ip2"
 + name = "a2"
 + ttl = 10
 + zone_name = "dns1"
 },
 ]
`
```
I used a default value and an output to test the expected result. Here's my full test, which you can run terraform plan for to show the output
```
`variable "dns_target_child_zones" {
 type = list(object({
 name = string
 a_records = list(object({
 name = string
 ttl = number
 ip_address = string
 }))
 cname_records = list(object({
 name = string
 ttl = number
 record = string
 }))
 mx_records = list(object({
 name = string
 ttl = number
 record = list(object({
 preference = number
 exchange = string
 }))
 }))
 txt_records = list(object({
 name = string
 ttl = number
 record = list(object({
 value = string
 }))
 }))
 }))
 default = [{
 name = "dns1",
 a_records = [{
 name = "a1",
 ttl = 10
 ip_address = "ip1"
 },
 {
 name = "a2",
 ttl = 10
 ip_address = "ip2"
 }
 ],
 cname_records = [{
 name = "cname1",
 ttl = 10
 record = "rec1"
 }],
 mx_records = [{
 name = "mx1",
 ttl = 10,
 record = [{
 preference = 1,
 exchange = "exchange1"
 }, {
 preference = 2,
 exchange = "exchange2"
 }]
 }],
 txt_records = [{
 name = "txt1",
 ttl = 10,
 record = [{
 value = "val1"
 }]
 }]
 }]
}

locals {
 a_records = flatten([
 for v in var.dns_target_child_zones: [
 for record in v.a_records: {
 name = record.name
 zone_name = v.name
 ttl = record.ttl
 ip_address = record.ip_address
 }
 ]
 ])
}

output "a_records" {
 value = local.a_records
}
`
```
For further nesting extraction e.g with mx_records then you can add another for loop in your local like the below
```
` mx_records = flatten([
 for v in var.dns_target_child_zones : [
 for mx in v.mx_records : [
 for r in mx.record : {
 name = mx.name
 zone_name = v.name
 ttl = mx.ttl
 preference = r.preference
 exchange = r.exchange
 }
 ]
 ]
 ])
`
```
The above local outputs this result
```
` + mx_records = [
 + {
 + exchange = "exchange1"
 + name = "mx1"
 + preference = 1
 + ttl = 10
 + zone_name = "dns1"
 },
 + {
 + exchange = "exchange2"
 + name = "mx1"
 + preference = 2
 + ttl = 10
 + zone_name = "dns1"
 },
 ]
`
```

Analyze this docker incident and provide diagnosis and fix:

```
Why a service configured with only `expose` is able to communicate with internet?

Something confuse me about docker networking. I've a `docker-compose.yml` file which can be simplified like this:
```
`version: '3.8'
services:
 foo:
 ...
 networks:
 - main_network
 ports:
 - "3000:3000"
 bar:
 ...
 networks:
 - main_network
 expose:
 - "5000"
networks:
 main_network:
`
```
According to this answer, `expose`...

Expose ports without publishing them to the host machine - they’ll only be accessible to linked services. Only the internal port can be specified.

If this is true, `bar` should only expose the 5000 port to `foo` service. And It seems to work as expected. If, I run `bash` into `bar` service and execute:
```
`$ ss -lntu
`
```
The 5000 port is opened correctly:
```
`Netid State Recv-Q Send-Q Local Address:Port Peer Address:Port
...
tcp LISTEN 0 128 0.0.0.0:5000 0.0.0.0:*
...
`
```
As expected, from outside of my container, using a web browser for example, I cannot connect to this host. Also, If I run
```
`$ nmap -p1-65535 127.0.0.1
`
```
I can verify that only the 3000/TCP port of `foo` service is opened:
```
`PORT STATE SERVICE
3000/tcp open ppp
`
```
So, what I don't understand is that IRL, my `bar` service is able to connect to Mongo Atlas online or ping internet. How does it get it's answer if the ports aren't Exposed/Opened in order to receive it?
```

[Assistant]
The answer to which you have linked is old and incorrect.

The `EXPOSE` keyword is primarily a no-op. It's informative ("this image will offer services on these ports"), but it doesn't have any operational impact.
In older versions of Docker, the `EXPOSE` keyword could be used for service discovery by linked containers, but (a) it still didn't have any operational impact -- the ports were available whether or not there was a matching `EXPOSE` -- and container "linking" has been deprecated for a quite some time.

Containers have outbound internet access by default. Outbound access is managed with a simple NAT rule in the host firewall `nat` table (and corresponding rules in the `filter` `FORWARD` chain). E.g., on a system where I am running Docker 20.10.2, in the `FORWARD` chain I have:
```
`-A FORWARD -o docker0 -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT
-A FORWARD -o docker0 -j DOCKER
-A FORWARD -i docker0 ! -o docker0 -j ACCEPT
-A FORWARD -i docker0 -o docker0 -j ACCEPT
`
```
The first rule passes packets that are part of an existing TCP connection. This permits the return packets for your outbound connections.

Parsing error: Cannot read file '\tsconfig.json' eslint after following Firebase Cloud Functions initialization instructions

Problem
Right after my TypeScript project initialization in VSCode using firebase tools for composing Firebase Cloud Functions following the official documentation the very first line of the `index.ts` file displays an error:
`Parsing error: Cannot read file '\tsconfig.json' eslint [1,1]`

and the `.eslintrc.js` displays an error:
`File is a CommonJS module; it may be converted to an ES6 module.ts(80001)`

Since all files are auto-generated these errors are a complete surprise and I want to get rid of them.
Versions
For the record, here are the versions installed:
```
`npm --version 8.1.3
tsc --version 4.4.4
node --version 17.0.1
firebase --version 9.22.0
`
```
Installation process
These are the commands I used in the powershell in VSCode with some info/warnings:
```
`>npm install -g firebase-tools
npm WARN deprecated har-validator@5.1.5: this library is no longer supported
npm WARN deprecated uuid@3.4.0: Please upgrade to version 7 or higher. Older versions may use Math.random() in certain circumstances, which is known to be problematic. See https://v8.dev/blog/math-random for details.

>firebase init

npm WARN EBADENGINE required: { node: '14
```

[Assistant]
Ok, I have solved the problem with a great help of this github thread
False positive Error - TS6133 error (declared but its value is never read) report.
I have changed `"noUnusedLocals"` setting in the `tsconfig.json` file from the default `true` to `false`, so the file becomes:
```
`"compilerOptions": {
 ...
 "noUnusedLocals": false,
 ...
 }
`
```
However, the strange thing is that after successfully deploying functions to `Firebase Cloud Fuctions` using this setting and afterwards reverting the changes, the redeployment doesn´t show any error and is successful as well.
Update
After retrying it a few time I must admit that the solution is different.
Turns out that the related stackoverflow thread did help, in particular @cherryblossom solution. Setting `tsconfigRootDir: __dirname` in the `.eslintrc.js` file and restarting the VSCode solves the problem.
`.eslintrc.js`:
```
`module.exports = {
 // ...
 parserOptions: {
 ...
 tsconfigRootDir: __dirname,
 ...
 },
 // ...
}
`
```

Docs: browserDebugInfoInTerminal is no longer experimental

### What is the documentation issue?

Docs show `browserDebugInfoInTerminal` as still experimental in NextJS 16.1.6 (it is not):
https://nextjs.org/docs/app/api-reference/config/next-config-js/browserDebugInfoInTerminal
<img width="3024" height="1716" alt="Image" src="https://github.com/user-attachments/assets/fd40ee68-ab91-4a5a-879a-ef2e0be3e50c" />

### Is there any context that might help us understand?

When implementing on my NextJS 16 app, there is a type error
<img width="1075" height="113" alt="Image" src="https://github.com/user-attachments/assets/13e2db81-3ac2-47bb-80bd-c2c8ecac0635" />

Turns out just needs to be moved out of experimental, and it resolves

[Assistant]
@WillGarman got any more input/update? Otherwise I'll close the issue.

For what is worth, `browserToTerminal` (top level), will be the way to go on 16.2 - with `experimental.browserDebugInfoInTerminal` entering deprecated status.

[Assistant]
This is a known issue in Next.js 15+ (especially with Turbopack or certain externals handling), reported in GitHub discussions [#77721](https://github.com/vercel/next.js/discussions/77721) and [#86194](https://github.com/vercel/next.js/discussions/86194).

Present fix options:

- Upgrade to latest Next.js canary (npm install next@canary)
- There are many similar filename sanitization fixes landed post-15.0.
- Disable Turbopack if using --turbo (next build without flag).
- Avoid output: 'standalone' in next.config.js if possible (use Vercel or container without standalone).

- Workaround: post-build script to rename/replace : → _ in .next/server/chunks/**/* filenames before copying.

I am taking a helm chart class and the 1st lab creates a pod, service and ingress. I am relatively new to k8s and I am running on minikube. The pod and service get created without issue; however the ingress.yaml file gives the following error:

```
python psycopg2 select current_timestamp problem with timezone

I'm calling a simple select to obtain current timestamp with timezone with psycopg2 and it's retrieving UTC time instead of my local time (-3).
datetime.datetime(2021, 1, 13, 20, 49, 47, 931834, tzinfo=psycopg2.tz.FixedOffsetTimezone(offset=0, name=None))
In postgresql I'm doing:
```
`select current_timestamp
`
```
This retrieves (Argentina time -3):
```
`2021-01-13 17:39:57
`
```
So this is correct, but in Python:
```
`class DatabaseUtils():
 def __init__(self):
 self.dsn = "dbname=my_database user=postgres host=127.0.0.1"
 self.conn, self.cur = self.connect_db()
 self.database_name = "my_table"

 def connect_db(self):
 """
 :param DSN: data source name. ex: "dbname=sigbase user=postgres"
 :return: connection, cursor Select method retrieves:
```
`Selected records [(datetime.datetime(2021, 1, 13, 20, 49, 47, 931834, tzinfo=psycopg2.tz.FixedOffsetTimezone(offset=0, name=None)),)]
`
```
So datetime object is comming with offset 0, i.e UTC.
Is it possible to retrieve current timestamp in psycopg2 with the proper timezone?
If not, how can I convert the datetime object timezone?
```

[Assistant]
I solved this issue in this way:
I added a method in the class init to set the timezone. In this way, the SELECT statements are giving the proper time.
```
`def set_timezone(self):
 # Get current time zone.
 timezone = datetime.datetime.now(datetime.timezone.utc).astimezone().tzname()
 # Set timezone.
 self.cur.execute(f"SET TIME ZONE {timezone};")
`
```
Result logged in python is:
```
`Selected records [(datetime.datetime(2021, 1, 14, 14, 21, 18, 455322, tzinfo=psycopg2.tz.FixedOffsetTimezone(offset=-180, name=None)),)]
`
```
This is correct (Argentina time now).
Extra info:
I based on the psycopg documentation, in the example is telling the timezone first, before the query. I think the select current_time in this library is working in UTC by default.

It errors with
TypeError: list indices must be integers or slices, not str

So I attempted to use Decimal, float, or int...

`
```
but get
```
`#Decimal

TypeError: Cannot convert 1 to Decimal128

#float

`
```
removing altogether
```
` list_of_dict[k] = Decimal128(v)
`
```
just gives the original 'not str' TypeError:
I'm sure it's something easy that i'm just not seeing. I know you can't
```

[Assistant]
Let's take a closer look at the line at which an error is being raised:
` list_of_dict[k] = Decimal128(str(v))
`
`list_of_dict` is a list, `k` is a key from one of the `dict`s. From your error message, `k` is evidently a string. If you're indexing a list, you should be using list indexes, not `dict` keys.
What you seem to want to do is to convert a single decimal value in one of the `dict`s to Decimal128. The current `dict` you are iterating through is in the variable `i`, so try changing the line above to this:
` i[k] = Decimal128(str(v))
`
(You might also want to consider improving the name of the variable `i`, both to make it more descriptive, and also because `i`, `j`, `k` etc. are often used as loop counter variables containing integer values.)
Finally, I must state that this code hasn't been tested. I don't have a copy of MongoDB installed.

feature: add a GitHub action to quell spam PRs

## Problem
I was scrolling through Twitter and someone posted about [the spam PR](https://github.com/expressjs/express/pulls?page=1&q=is%3Apr+is%3Aclosed+Readme.md).

## Possible Solution
Implement this [GitHub action](https://github.com/marketplace/actions/mark-as-spam). It'll lessen the workload for maintainers.
```

[Assistant]
> This is why I am hesitant do add an action for this as I would rather ask GitHub for better spam management tooling.

Agree with @wesleytodd. The issue is quite complex because the moderation in GitHub is not an easy thing:
- Many people (those that are watching the repo) will receive a notification in their email or in the app/web once a new PR is created. This will occur even before a Github Action is triggered.
- Closing PRs is an easy action (1 click), so that is not a big time consumer
- Detecting invalid PRs is not the big issue because you can easily to spot them with the practice.
- Reporting issues/users is complex because the UI requires many steps to do it for each user, so that is a blocker for many maintainers.
- Nuke button like @CBID2 suggested is great when the community needs to slow down due a discussion/flame in certain moments, but is not the long term solution as it will prevent other users from contributing (PRs) that are legit or need help (issues) while using Express.

So, I think that we are quite limited on how much we can do with GitHub actions in this case. There are other scenarios that are less frequent but more prone to use GitHub Actions to moderate, for example when people do comments that include offensive content or heavily language. In most projects that I am involved the moderation is done by the humans behind the project or a specific team that volunteer to do it, it is a heavy job. The same way as it is hard to keep a slack/discord/gitter community channel a safe space by moderating content.

---

I do agree that workflow is a bit more well suited IMO. I am still hesitant and I would like to also look at other ways but yeah in the mean time lets re-open the issue so we don't end up having multiple on the same topic or miss out on good ideas like @gaurishhs'.

---

And if word count check is added, they must find some other way to open spam prs. The problem here is those who make spam prs, they just started their development journey and when they got introduced to github (by some youtubers or some articles), they tried to test it by themselves. They didn't have any idea that the thing they are doing is a headace of someone else.

**The only way we can stop this is by creating awarness.**

I am having this table which I migrated from MySQL using pgLoader
```
`CREATE TABLE IF NOT EXISTS schema.example
(
 "ExampleID" integer NOT NULL,
 "Name" character varying(255) COLLATE pg_catalog."default" NOT NULL,
 CONSTRAINT "idx_43997_PRIMARY" PRIMARY KEY ("ExampleID"),
)
`
```
I am trying to convert the ExampleID to be serial so it will auto increment using this method:
Changing primary key int type to serial
So I am doing
```
`CREATE SEQUENCE example_id_seq MINVALUE 3
`
```
Which works fine, but then
```
`ALTER TABLE example ALTER "ExampleID" SET DEFAULT nextval('example_id_seq')
`
```
Gives the error:
```
`ERROR: cannot use column reference in DEFAULT expression
SQL state: 0A000
`
```
But if I remove the "" and just put ExampleID like that:
```
`ALTER TABLE example ALTER ExampleID SET DEFAULT nextval('example_id_seq')
`
```
I will get the error
```
`ERROR: column "exampleid" of relation "example" does not exist
SQL state: 42703
`
```
```

[Assistant]
The problem was that unlike in the example
```
`ALTER TABLE example ALTER "ExampleID" SET DEFAULT nextval('example_id_seq')
`
```
I forgot to put ' ' next to the sequence name so it was
```
`ALTER TABLE example ALTER "ExampleID" SET DEFAULT nextval(example_id_seq)
`
```
The column reference was that it mistaken the sequence for column name reference.

Turbopack Error: Next.js package not found

Turbopack version: `fa536cf2`

Error message:
```
Next.js package not found

Debug info:
- Execution of get_entrypoints_with_issues_operation failed
- Execution of EntrypointsOperation::new failed
- Execution of Project::entrypoints failed
- Execution of AppProject::routes failed
- Execution of directory_tree_to_entrypoints_internal failed
- Execution of get_next_package failed
- Next.js package not found
```
```

[Assistant]
Thanks for the report! This error usually happens when Turbopack determined your project’s root directory based on a lockfile that exists further down the filesystem than where next is installed.

For example, something like this:

```
repo/
 package.json
 package-lock.json
 node_modules/next
 apps/
 my-app/
 package.json
 package-lock.json
 app/
 page.tsx
```

Here, Turbopack determined the root directory to be `my-app`, but Next.js is installed further up the tree.

You’ll need to either:
- Remove the lockfile inside `my-app` if possible, or
- Set `turbopack.root` in to `next.config.js` to your repository’s root directory (or wherever Next.js is installed), as described [here](https://nextjs.org/docs/app/api-reference/config/next-config-js/turbopack#root-directory)

We’re working on a better way of communicating this problem, and exploring other approaches where the root directory can be better discovered automatically.

Using depend_on with stack

The documentation for depends_on states:

There are several things to be aware of when using `depends_on`:

`depends_on` does not wait for `db` and `redis` to be “ready” before starting `web` - only until they have been started. If you need to wait
for a service to be ready, see Controlling startup order for more on
this problem and strategies for solving it.

The `depends_on` option is ignored when deploying a stack in swarm mode with a version 3 Compose file.

So, does this mean when I'm using swarm mode and version 3 compose file to deploy it will ignore all conditions under depends_on? For example:
```
`version: "3"
services:
 web:
 build: .
 ports:
 - "80:8000"
 depends_on:
 - "db"
 command: ["./wait-for-it.sh", "db:5432", "--", "python", "app.py"]
 db:
 image: postgres
`
```
```

[Assistant]
Pretty correct, `swarm` as a orchestration will ignore the `depends_on`.
But for your scenario, `depends_on` is really not necessary as you already have `wait-for-it.sh` which have better control than `depends_on` to assure the start order.

You can control the order of service startup and shutdown with the depends_on option. Compose always starts and stops containers in dependency order, where dependencies are determined by depends_on, links, volumes_from, and network_mode: "service:...".
However, for startup Compose does not wait until a container is “ready” (whatever that means for your particular application) - only until it’s running. There’s a good reason for this.
There are limitations to this first solution. For example, it doesn’t verify when a specific service is really ready.
Alternatively, write your own wrapper script to perform a more application-specific health check. For example, you might want to wait until Postgres is ready to accept commands

Details see Control startup and shutdown order in Compose, so you no need `depends_on` in your solution.

About a week or so ago lots of our builds were failing, MS had changed something and we were getting this sort of thing:

However was able to solve this by explicitily adding a task to include the netcore2.1 sdk
` - task: UseDotNet@2

`
Now this issues is fixed we are now posed with the error complaining it cannot find .NET Framework 4.6.1.
Anyways any idea whats going on, this is driving me banannas - any advice or insight greatly appreciated.
```

[Assistant]
The .Net framework version `4.6.1` has been deprecated by Azure DevOps Microsoft-hosted agent. For now, there are two kinds of Microsoft-hosted agents:
`windows-2019` OR `windows-latest`: .Net framework version `4.7.2` and `4.8` preinstalled. This is documented here.
`windows-2022`: .Net framework version `4.8` preinstalled. This is documented here.
That is, you need to use self-hosted agent to use .Net framework `4.6.1` in the pipeline.

...

google_storage_bucket.buckets: Importing from ID "a-test-test-test"...

`terragrunt state list
...
google_storage_bucket.buckets
`
its show in my tfstate, but it should be like this
`google_storage_bucket.buckets["a-test-test-test"]
`
because if I run now apply - it says it wants to delete the `google_storage_bucket.buckets` and create `google_storage_bucket.buckets["a-test-test-test"]`
`google_storage_bucket.buckets: Refreshing state... [id=a-test-test-test]

An execution plan has been generated and is shown below.
Resource actions are indicated with the following symbols:
 + create
 - destroy

Terraform will perform the following actions:

 # google_storage_bucket.buckets will be destroyed
 - resource "google_storage_bucket" "buckets" {
 - bucket_policy_only = false -> null
 - default_event_based_hold = false -> null
 - force_destroy = false -> null
 - id = "a-test-test-test" -> null
 - labels = {} -> null
 -
```

[Assistant]
Importing into the full instance address (including the instance key index part) is the right approach, but the trick here is to determine the best way to work around the grammar of your shell so that the necessary characters can reach Terraform.
For Unix-style shells I typically recommend putting the address in single quotes to disable metacharacter interpretation, like this:
```
`terragrunt import 'google_storage_bucket.buckets["a-test-test-test"]' a-test-test-test
`
```
I don't have much experience with `zsh` in particular but from referring to a copy of part of its documentation I get the impression that the above is valid `zsh` syntax too. If the above doesn't work, it might be worth trying with a different shell such as `bash` to see if you get a different result.
Although you specifically mentioned `zsh`, for completeness I'll also note that on Windows the rules are a little different: single quotes aren't supported under the conventional Windows command line syntax, and so unfortunately we must escape the quotes instead when running Terraform from the Windows command prompt:
```
`terragrunt import google_storage_bucket.buckets[\"a-test-test-test\"] a-test-test-test
`
```
The important thing is that the quote characters `"` in the address make it through the shell to Terraform, so that Terraform can then successfully parse the argument as resource address syntax.

`E1219 16:07:37.556979 22674 runtime.go:142] "Observed a panic" panic="runtime error: invalid memory address or nil pointer dereference" panicGoValue="\"invalid memory address or nil pointer dereference\"" stacktrace=<`

**What you expected to happen**:

Get the filtered envs

**Anything else we need to know?**:

I checked the stacktrace and it showed me this:

```

So I checked what is it [there](https://github.com/kubernetes/kubectl/blob/master/pkg/cmd/exec/exec.go#L414). After I saw that the initialization of the delegate field happening [here](https://github.com/kubernetes/kubectl/blob/master/pkg/cmd/exec/exec.go#L370).

Delete Redis keys matching a pattern

I am using Redis hash set to store data in the following format:
```
`hset b1.b2.b3 name test
`
```
Now I want to delete this key so I am using the following format:
```
`del b1.b2.*
`
```
But it not working so how I delete the Redis key using a pattern?
```

[Assistant]
Redis does not provide any method to delete bulk keys. But redis-cli along with xargs can be used to achieve what you are trying to do. See the commands below:
```
`127.0.0.1:6379> hset b1.b2.b3 name test
(integer) 1
127.0.0.1:6379> hgetall b1.b2.b3
1) "name"
2) "test"
$ redis-cli --scan --pattern b1.b2.* | xargs redis-cli del
(integer) 1
$ redis-cli
127.0.0.1:6379> hgetall b1.b2.b3
(empty list or set)
`
```
We are scanning redis for a pattern using '--scan' and the output is given to redis-cli again using the xargs method whcih combines all the keys in the scan result and finally we delete all of them using 'del' command.

Analyze this nginx incident and provide diagnosis and fix:

```
Nginx - Custom configuration files location

I use Nginx with many domains. Some of these domains have custom configurations. I'm including these files inside the server blocks in the Nginx configurations.
For example:
```
`server {
 ... some configurations things here...
 include /var/somewhere/custom.conf;
 etc.. etc..
}
`
```
The configuration files of Nginx are inside: /etc/nginx
To try and keep everything in one place and not have my custom configuration files all over the place I would like to place my custom configuration files inside /etc/nginx/some_directory
Can I create a sub directory inside /etc/nginx without it causing any issues with Nginx itself? I want to create /etc/nginx/some_directory/ and place my many custom configuration files inside it and include them.
I'm specifically asking this question because I don't want to break something on my production server.
```

[Assistant]
If nginx doesn't know about a directory, it'll not touch it. You can verify that by `grep`ing against such pattern in nginx's codebase.
However, messing with a foreign folder structure might cause problems with permissions and ownership of the files, therefore either just use a pre-defined folders nginx prepared for you (`/etc/nginx/sites-enabled` and `/etc/nginx/sites-available`) which you can use with symlinks such as nginx itself does
```
`# ls /etc/nginx/sites-enabled
default -> /etc/nginx/sites-available/default

# ls /etc/nginx/sites-available
default
`
```
otherwise you're getting into a situation what C/C++ programmers call an undefined behavior and there's no guarantee that what works now will work in the future / nginx doesn't change as well as the distro maintainers might mess with the folder structure and permissions for the packages in distro package manager.
Example:
Nginx might verify the full `/etc/nginx` tree's permissions and owners - if your folders/files don't match it might cause a warning or crash even. If it's installed by a package manager, it might cause issues when removing the package itself e.g. if the package manager attempts to remove only a known list of folders + afterwards the parent i.e. `/etc/nginx` by `rmdir` or similar. Situations you don't really want to get into and debug when you can use allowed folders or symlinks or your own folders that are not bound to an application or behavior except the one you define.

Analyze this kubernetes incident and provide diagnosis and fix:

```
Presently, when kubectl is used to apply a large manifest that defines new custom resource definitions (CRDs) as well as resources that use the new resource kind, conditions can cause the deployment to fail. Assuming you're using `kubectl apply -f -` and an external `kustomize` you might see an error like:

```
unable to recognize "STDIN": no matches for kind "Alertmanager" in version "monitoring.coreos.com/v1"
```

(the exact resource "kind" and api "version" will vary depending on what you're deplying).

This appears to be a race between the k8s cluster applying the new CRD types and kustomize sending requests that use the new types, but there's no indication of that in the command's output. It's confusing for new users, and it's a hassle operationally since deployments will fail then work when re-tried. This is something the `kubectl` tool could help users with.

The `--server-side` option does not help, as the same race occurs then. And `--wait=true` only affects resource removal, not creation.

This can often be reproduced with a kind cluster, though it varies since it's a race. For example:

```
kind create cluster
git clone -b v0.8.0 https://github.com/prometheus-operator/kube-prometheus
kubectl apply -k kube-prometheus/
```

... which will often fail with:

```
daemonset.apps/node-exporter created
unable to recognize "kube-prometheus/": no matches for kind "Alertmanager" in version "monitoring.coreos.com/v1"
unable to recognize "kube-prometheus/": no matches for kind
```

[Assistant]
A workaround is to use `kfilt` to deploy the CRDs first, then wait for them to become visible, then deploy the rest:

 kustomize build somedir | kfilt -i kind=CustomResourceDefinition | kubectl apply -f -
 kustomize build somedir | kfilt -i kind=CustomResourceDefinition | kubectl wait --for condition=established --timeout=60s -f -
 kustomize build somedir | kubectl apply -f -

Thank you so much for the `kfilt` example above. I am running into this in another way.

My vagrant provisioning step fails because [k3s](https//k3s.io/) is installed but did not complete setting up traefik. So sometimes applying my resources failed with

```
default: error: unable to recognize "/vagrant/traefik_certificate.yaml": no matches for kind "TLSStore" in version "traefik.containo.us/v1alpha1"
```
So I can now fix this with

```shell
$ kubectl wait --for condition=established crd tlsstores.traefik.containo.us
```
Thanks! I agree that a more generic solution in kubectl would be great.

I'm getting this error:
`cannot read certificate file: /etc/ssl/mongodb-test-ca.key error:0909006C:PEM routines:get_name:no start line`
It looks like there is some problem with the .pem files that I'm using. To configure them, I've followed the instructions here https://www.mongodb.com/docs/manual/appendix/security/appendixA-openssl-ca/
More specifically, the commands I've used are, after creating that `openssl-test-ca.cnf` file that they suggest are:
```
`openssl genrsa -out mongodb-test-ca.key 4096
openssl req -new -x509 -days 1826 -key mongodb-test-ca.key -out mongodb-test-ca.crt -config openssl-test-ca.cnf
openssl genrsa -out mongodb-test-ia.key 4096
openssl req -new -key mongodb-test-ia.key -out mongodb-test-ia.csr -config openssl-test-ca.cnf
openssl x509 -sha256 -req -days 730 -in mongodb-test-ia.csr -CA mongodb-test-ca.crt -CAkey mongodb-test-ca.key -set_serial 01 -out mongodb-test-ia.crt -extfile openssl-test-ca.cnf -extensions v3_ca
cat mongodb-test-ca.crt mongodb-test-ia.crt > test-ca.pem
`
```
What am I doing wrong? One idea is that the files that I'm using were not the correct ones, but I'm only seeing one .pem file on my process, the `test-ca.pem`. For the key `tlsCertificateKeyFile` I've tested also `mongodb-test-ca.key` `and mongodb-test-ia.key` without success
```

You must create the `.pem` like this:
```
`cat mongodb-test-ia.crt mongodb-test-ia.key > mongodb-test-ia.pem

and then run mongod with
```
`--tlsCertificateKeyFile /etc/ssl/mongodb-test-ia.pem --tlsCAFile /etc/ssl/test-ca.crt

In order to test the certificates you can also use `openssl`. Try
```
`openssl verify -CAfile /etc/ssl/mongodb-test-ca.crt /etc/ssl/mongodb-test-ia.pem
`
```
Or if you like to do it a bit more advanced, open a shell and enter
```
`openssl s_server -cert /etc/ssl/mongodb-test-ia.pem
`
```
Then open another shell and use
```
`openssl s_client -CAfile /etc/ssl/mongodb-test-ca.crt -quiet -no_ign_eof -status See also How Security in MongoDB works (using x.509 cert)

Analyze this nginx incident and provide diagnosis and fix:

```
Ingress Nginx throwing a client request body is buffered to a temporary file warning

We have an ingress resource hostname say `xyz.int.com` setup on two k8s cluster A and B. The ingress controller used is nginx. On DNS we have setup `xyz.int.com` to point to the loadbalancer IPs in respective clusters.
For some strange reason, in one cluster I'm getting the below warning and not getting any status code for request if its a success or not:
```
`2022/01/17 17:58:00 [warn] 13239#13239: *94097411 a client request body is buffered to a temporary file /tmp/client-body/0001505726, client: 10.9.8.0, server: xyz.int.com, request: "POST /api/vss0/an/log/83f740daa89b3d3638b37a6a06de49a59f1f5126129a9a6?clientTimeInMs=1642442284833&sdkV=811409&gpid=a15e3b7c2-e1366-4327d-83a93-f7619&devNet=WIFI&locale=en-IN&region=IN HTTP/1.1", host: "xyz.int.com"
`
```
Whereas the same endpoint in another cluster works fine, and there is no explicit difference in both the nginx controller or ingress resource.
What can be the issue? Kindly assist.
```

[Assistant]
Summarizing the comments:
This warning message means that the size of the uploaded file was larger than the in-memory buffer reserved for uploads.
Please refer to this description explaining how `client_body_buffer_size` works:

Sets buffer size for reading client request body. In case the request body is larger than the buffer, the whole body or only its part is written to a temporary file. By default, buffer size is equal to two memory pages. This is 8K on x86, other 32-bit platforms, and x86-64. It is usually 16K on other 64-bit platforms.

Callback for user's responses in a telegram bot (Telegraf)

I'm coding a telegram bot with Telegraf on node.js and I need to get some information about users. For example, the bot is asking them where they are from. Then, I want to wait for the user's response and store it in my db. However, I don't understand how to achieve that since I can't just use a `bot.on('text', ...)` because I'm asking multiple questions and need to differenciate responses afterwards. I found out that there are callbacks but all that I found is for buttons and keyboards. Thanks!

```
[BUG] in redis cluster, if an instance restart, it cannot use psync, but always full sync from master.

**Describe the bug**

in cluster-mode, if an instanse restart, it will generate an new master-replid, when it connect to the master, the requested master-replid mismatch the info replication of the master. so the master will do bgsave, and the slave always reload the data from the master by using full sync.

**To reproduce**

builld an redis cluster, such an using 3 masters and 3 slave as a cluster. you can select an instance to restart, then analysis the master log. you can get mismath, and full sync information.

**Expected behavior**

when the instance restart, it can psync from master.

**Additional information**

Any additional information that is relevant to the problem.

Analyze this terraform incident and provide diagnosis and fix:

```
│ Error: expected version to be one of ["15" "14" "11" "16" "13" "12" "17"], got 18

│ with azurerm_postgresql_flexible_server.postgresServer,
│ on data.tf line 38, in resource "azurerm_postgresql_flexible_server" "postgresServer":
│ 38: version = "18"
```

### Expected Behaviour

PostgreSQL 18 is out and [azure supports it](https://learn.microsoft.com/en-us/azure/postgresql/flexible-server/concepts-supported-versions).

I'd therefore also expect terraform to create / update the resource, when choosing version 18.

### Actual Behaviour

Fails - doesn't accept version 18.

### Steps to Reproduce

Run the example above

### Important Factoids

_No response_

### References

What are the plans to support version 18? I see version 17 got supported a few weeks ago - whereas the release date for PostgreSQL was in September 2024, i.e. about a year ago.

Support .noderc or similar file-based initialization configurations?

In https://github.com/nodejs/node/issues/52219 it was mentioned that for APM use cases it would be nice to have a way to register loaders without using command line flags. It occurred to me maybe what we need is an initialization config similar to the rc files out there for various applications.

For example in my `.lldbinit` I have these that extend LLDB to help me debug

```
plugin load /path/to/llnode.dylib
command script import /path/to/lldb_commands.py
```

It seems this is serving the same use case as the Node.js loader registration - run some scripts or register some plugin to Node.js before you actually start running it.

For loading loaders, I guess we can support something like a `.noderc` that is discovered when users start running Node.js, or make that part of `package.json`, which allows registering certain hooks before the actual application code is run. For example in the case of package.json, I guess the project pacakge.json would include something like this:

```
{
 "preload": [
 "apm-package/register"
 ],
 "dependencies": {
 "apm-package": "1.1.1"
 }
}
```

If we want something more flexible than "just loading some scripts" though, I guess a dedicated rc file would be easier to use than package.json.

cc @timfish @nodejs/loaders
```

[Assistant]
I was thinking that whatever config file we choose would be loaded automatically as a semver-major change, and a flag could specify it for older Node versions. A flag might be used for the latest version too in case the user wants to specify a file that’s not the default filename or location.

I’m not sure what about https://github.com/nodejs/node/issues/41103 involves any of this. We should just filter out options that don’t make sense to inherit, both currently to resolve that issue and in the future when we add a proper config file. We should do that filtering however the problematic options are defined, such as via environment variables or `NODE_OPTIONS` or via a file. Users already have ways to exert granular control of what flags and/or environment variables are passed into child processes or workers, via `execArgv` or `env`.

---

> A nodejs section in package.json is ideal. Make it so that if it's a string, then that's the name of a file to load, like many other tools do. Then we don't have to agree on the perfect spelling for the filename.

I am leaning towards "a field specified in package.json pointing to a file" too primarily because to load this by default, it adds overhead to the startup to probe the file system; And since we already probe the file system for package.json, the overhead of probing another field in it would be the smallest.

But I do like to see a fixed (at least base) name of the file, because I like the concept of universally recognizable manifest of projects, just like when I check out a JS project/package, if I want to see dependency information I go to package.json, if I want to see TypeScript information I go to tsconfig.json, if I want to see their eslint configs I go to any file that contains the word eslint etc. Maybe something we can do is to support multiple formats (like what eslint does), and JSON would be the first to support, but they all have the same basename, and people just pick the format they like, provided that we do add support for other formats later on.

---

Would this preload apply only to `package.json#scripts` or to any node process where this `package.json` is resolved as the closest?

Getting failed calling webhook "validate.nginx.ingress.kubernetes.io": error when applying ingress resource/rules yaml file in NginxIngress Controller

I'm getting below error whenever I'm trying to apply an ingress resource/rules yaml file:
failed calling webhook "validate.nginx.ingress.kubernetes.io": Post "https://ingress-nginx-controller-admission.ingress-nginx.svc:443/networking/v1/ingresses?timeout=10s": EOF
It seems there are multiple errors for "failed calling webhook "validate.nginx.ingress.kubernetes.io": Post "https://ingress-nginx-controller-admission.ingress-nginx.svc:443/networking/v1/ingresses?timeout=10s": Error here
Like below:

no endpoints available for service "ingress-nginx-controller-admission"

...and many more.
My Observations:
As soon as the the ingress resource/rules yaml is applied, the above error is shown and the Ingress Controller gets restarted as shown below:
```

Ok, I got this working now:
I was getting the status as "OOMKilled" (Out Of Memory). So what I did is I've added the "limits:" section under "resources:" section of Deployment yaml as below:
```
` resources:

CVE-2026-24514: ingress-nginx Admission Controller denial of service

CVSS Rating: [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H](https://www.first.org/cvss/calculator/3.1#CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)

A security issue was discovered in [ingress-nginx](https://github.com/kubernetes/ingress-nginx) where the validating admission controller feature is subject to a denial of service condition. By sending large requests to the validating admission controller, an attacker can cause memory consumption, which may result in the ingress-nginx controller pod being killed or the node running out of memory.

### Am I vulnerable?

* This issue affects ingress-nginx. If you do not have ingress-nginx installed on your cluster, you are not affected. You can check this by running \`kubectl get pods \--all-namespaces \--selector [app.kubernetes.io/name=ingress-nginx](http://app.kubernetes.io/name=ingress-nginx)\`.

#### Affected Versions

- ingress-nginx: < 1.13.7
- ingress-nginx: < 1.14.3

### How do I mitigate this vulnerability?

ACTION REQUIRED: The following steps must be taken to mitigate this vulnerability: Upgrade ingress-nginx to v1.13.7, v1.14.3, or any later version.

#### How to upgrade?

To upgrade, refer to the documentation: [Upgrading Ingress-nginx](https://kubernetes.github.io/ingress-nginx/deploy/upgrade/)

### Detection

Requests larger than a few megabytes being sent to the ingress-nginx admission controller may indicate an attempt to exploit this vulnerabil

Why Async is not actually async?

line 4074 of `redis/commands/core.py` (https://github.com/redis/redis-py/blob/8325ce2859b28e61086da904fba6ba87a4ee3d1b/redis/commands/core.py#L4074C1-L4074C37)
`AsyncStreamCommands = StreamCommands`

also this in `redismodulecommands` line 94:
`class AsyncRedisModuleCommands(RedisModuleCommands)`

and we can go on and on

As I see, if we want asynchronous code, now we need to use `redis.asyncio.execute_command` method every time, because all wrappers are synchronous (with some exceptions).

Why we don't have asynchronous wrappers?
```

also as was pointed out here #3569 we don't have async TimeSeries, but the problem is bigger, we don't have async wrappers for most of the features

Analyze this terraform incident and provide diagnosis and fix:

```
replace_triggered_by doesn't report error if given attribute references don't exist

### Terraform Version

```shell
Terraform v1.11.2
on linux_amd64
```

### Terraform Configuration Files

```terraform
resource "null_resource" "r1" {
}

resource "null_resource" "r2" {
 lifecycle {
 replace_triggered_by = [null_resource.r1.foo.bar.baz[0].bif] # does not error, but should
 # replace_triggered_by = [null_resource.r3] # correctly reports error
 }
}
```

### Debug Output

none

### Expected Behavior

I expect the configuration above to yield an error. `null_resource.r1.foo.bar.baz[0].bif` is not a real attribute reference.

### Actual Behavior

```
$ terraform apply
null_resource.r1: Refreshing state... [id=1800298252482723122]
null_resource.r2: Refreshing state... [id=3647057674329973682]

No changes. Your infrastructure matches the configuration.

Terraform has compared your real infrastructure against your configuration and found no differences, so no changes are needed.

Apply complete! Resources: 0 added, 0 changed, 0 destroyed.
```

### Steps to Reproduce

1. `terraform init`
2. `terraform apply`

### Additional Context

Since `replace_triggered_by` is expecting a list of resources or attributes, I'd expect that it would check that those references at least were valid references. It's extremely easy to make a mistake here (e.g., forgetting [0], or a typo, etc) and for a resource not to get replaced because of that typo.

EDITED 2022-10-31
Release notes for Docker Desktop (4.13.1) (and following versions), states that, there is no need to create the symlink anymore, citing notes:

Added back the `/var/run/docker.sock` symlink on Mac by default, to increase compatibility with tooling like `tilt` and `docker-py`. Fixes docker/for-mac#6529.

The official fix now is to UPGRADE your Docker Desktop installation.
For the Docker Desktop (4.13.0) version:
By default Docker will not create the /var/run/docker.sock symlink on the host and use the docker-desktop CLI context instead. (see: https://docs.docker.com/desktop/release-notes/)
That will prevent IntelliJ from finding Docker using the default context.
You can see the current contexts in your machine by running `docker context ls`, which should produce an output like:
```
`NAME TYPE DESCRIPTION DOCKER ENDPOINT KUBERNETES ENDPOINT ORCHESTRATOR
default moby Current DOCKER_HOST based configuration unix:///var/run/docker.sock https://kubernetes.docker.internal:6443 (default) swarm
desktop-linux * moby unix:///Users//.docker/run/docker.sock

`
```
As a workaround that will allow IntelliJ to connect to Docker you can use the TCP Socket checkbox and put in the Engine API URL the value that appears under `DOCKER ENDPOINT` in the active context.
The case for this example will be: `unix:///Users//.docker/run/docker.sock`
Then IntelliJ will be able to connect to Docker Desktop.
EDITED 2023-07-17
If the option in "Settings > Advanced > Allow the default Docker socket to be used" is already enabled and the socket is not available try disabling it and re-enabling it.

**Hacky option**
Another way to make IntelliJ (and other components that rely on the default config) to find Docker will be to manually create a symlink to the new `DOCKER ENDPOINT` by running:
```
`sudo ln -svf /Users//.docker/run/docker.sock /var/run/docker.sock
`
```
In that way all the components looking for Docker under `/var/run/docker.sock` will find it.

Have you tried deleting `.next` and `node_modules` and running npm (or yarn or pnpm) install again

Analyze this azure incident and provide diagnosis and fix:

```
But it's returning the error:
```
`(ResourceGroupNotFound) Resource group 'MyResourceGroup' could not be found.
Code: ResourceGroupNotFound
Message: Resource group 'MyResourceGroup' could not be found.
`
```
Even if I put the right Resource Group name.
So I tried with T-SQL:
```
`USE master;

DECLARE @databaseName NVARCHAR(128) = 'YourDatabaseName'; -- Replace with your database name
DECLARE @lastConnectionTime DATETIME;

-- Get the last connection time from the sys.dm_exec_sessions DMV
SELECT @lastConnectionTime = MAX(login_time)
FROM sys.dm_exec_sessions
WHERE database_id = DB_ID(@databaseName);

IF @lastConnectionTime IS NULL
BEGIN
 PRINT 'The database has never been connected since the last restart or creation.';
END
ELSE
BEGIN
 PRINT 'The database last had a connection at: ' + CONVERT(NVARCHAR, @lastConnectionTime);
END
`
```
Which returns `The database has never been connected since the last restart or creation.` which is a lie because I'm connected to it right now.
So how can I check the last time an Azure SQL Database went on Auto-Pause and for how long?
```

[Assistant]
I had the same question, but then I noticed Activity Log. It's possible to drill into the change details for the DB.
in the Azure Portal, go to the DB > Activity Log > choose an event (pausing & resuming are events, I found out). look for Properties.Status, properties.pausedDate, properties.ResumedDAte or something similar to get the last time paused or resumed. These details are change activities logged to Azure itself in the DB config. if you don't have permissions to see what history and values that have changed, you may not have the ability to see that information.

mongo convert single object to one element array

I have the following problem. In this example dataset:

 "@type": "Z08"
 }
 ]
 }
 },
 "text": "Test3"
 }
 ]
 }
 ]
 }
]
`
```
You will find that if only a single `answer` to a question exists it is represented as an object. If more than one exists then it is an array. This is also true in the `shape` node. I wonder what is the best way to convert those nodes to be always arrays (so if one answer exists it would be an array of one element).
```

[Assistant]
`$map` to iterate loop of `questions` array
check condition if answer is not array then put into array bracket and input as `$map` to iterate loop of `answer` array
check condition is not `shape` array ten wrap it in to array bracket
`$mergeObjects` with sub documents `img`, `m_IMG` objects
`$mergeObjects` with current document and updated `answer` array

```
`db.collection.aggregate([
 {
 $set: {
 questions: {
 $map: {
 input: "$questions",
 as: "q",
 in: {
 $mergeObjects: [
 "$$q",
 {
 answer: {
 $map: {
 input: {
 $cond: [
 { $eq: [{ $isArray: "$$q.answer" }, true] },
 "$$q.answer",
 ["$$q.answer"]
 ]
 },
 as: "a",
 in: {
 $mergeObjects: [
 "$$a",
 {
 m_IMG: {
 $mergeObjects: [
 "$$a.m_IMG",
 {
 img: {
 $mergeObjects: [
 "$$a.m_IMG.img",
 {
 shape: {
 $cond: [
 { $eq: [{ $isArray: "$$a.m_IMG.img.shape" }, true] },
 "$$a.m_IMG.img.shape",
 ["$$a.m_IMG.img.shape"]
 ]
 }
 }
 ]
 }
 }
 ]
 }
 }
 ]
 }
 }
 }
 }

 }

Server's socket.io listener fires twice for no apparent reason

I'm building an app with a chat feature using express.js, react.js and socket.io. Here is a minimal version with the bug reproduced on Github.
The problem is the server's `socket.on()` always fires twice, for no reason that is apparent to me.
As far as I can tell the client only ever sends a single `.emit`, but the server's `.on` always fires twice (and I'm fairly certain that event handler isn't bound twice), regardless of how many clients are connected, or indeed how I've refactored the code.
The sending client's form (input + button) appends the message to its local messages list and then dispatches `MESSAGE_NEW` to the reducer.
Here's first the `Socket.js` file.
```
`import React from 'react'
import socketio from 'socket.io-client'

export const socket = socketio.connect('ws://localhost:3001')
export const SocketContext = React.createContext()
`
```
And here is the submit handler code from `Chat.js` (this seems to work correctly, dispatching just once):
```
`const handleSubmit = e => {
 e.preventDefault()

 if (message === '') return

 setMessages(messages => [...messages, message])
 dispatch({ type: 'MESSAGE_NEW', payload: message })
 setMessage('')
}
`
```
Here's `/Reducer.js`, which `.emit`'s the signal (also seems to work fine, firing just once).
```
`import { useContext } from 'react'
import { SocketContext } from './Socket'

export default function Reducer(state, action) {
 const socket = useContext
... (truncated)
```

[Assistant]
As per React documentation's on strict mode:

Strict mode can’t automatically detect side effects for you, but it can help you spot them by making them a little more deterministic. This is done by intentionally double-invoking the following functions:

Class component `constructor`, `render`, and `shouldComponentUpdate` methods
Class component static `getDerivedStateFromProps` method
Function component bodies
State updater functions (the first argument to `setState`)
Functions passed to `useState`, `useMemo`, or `useReducer`

Notice the last line: functions passed to `useReducer` will be invoked twice; that is why your message is being sent twice. You can confirm this by updating your reducer like so:
` case "MESSAGE_NEW":
 alert("I'm running");
`
You'll notice this alert appearing twice, thanks to `React.StrictMode`.
If you remove the `` wrapper in `src/App.js` the `test` message will no longer repeat; however, it's not fixing the underlying issue here.
The underlying issue is that you're making your reducer (which should be pure) perform an impure side-effect (in this case, sending a message via a websocket). Additionally, the reducer function also has a `useContext` call – this is also a no-op from React's perspective and is not good practice.
As you've come across in your question, Simply move the `socket.emit` into your `handleSubmit` and you should be good to go. Alternatively, you can consider a more sophisticated setup if you wish to go the reducer route; some popular configurations include Redux + Redux Thunk, or Redux + Redux Saga. Your mileage may vary.

Set concatenated string as a application_name

I'm trying to set application_name with some concatenated string as shown below in the example:
Example:
```
`do
$$
declare var1 text := 'Text1';
 var2 text := 'Text2';
 result text;
begin
 set application_name = var1||'-'||var2;

 select application_name into result
 from pg_stat_activity where pid = pg_backend_pid();

 raise info '%',result;
end;
$$;
`
```
But getting an error:

SQL Error [42601]: ERROR: syntax error at or near "||" Position: 116
```

[Assistant]
Use `format` to concatenate the string and then `execute` it, e.g.
```
`do
$$
declare var1 text := 'Text1';
 var2 text := 'Text2';
 result text;
begin
 execute format('set application_name=%s',quote_ident(var1||'-'||var2));
 select application_name into result
 from pg_stat_activity where pid = pg_backend_pid();
 raise info '%',result;
end;
$$;
`

How to create secrets manager secret resource policy that references the secret itself using Terraform?

I'm trying to create a terraform script that creates an AWS secrets manager secret with a resource based policy that grants an IAM role permissions to `secretsmanager:GetSecretValue` on that specific secret.
I'm currently running into Terraform cycle issue between the secrets manager secret and the IAM policy document. Here's what my code looks like:
```
`resource "aws_secretsmanager_secret" "this" {
 name = "mySecret"
 policy = data.aws_iam_policy_document.this.json
}

data "aws_iam_policy_document" "this" {
 statement {
 sid = "ReadPermissions"
 principals {
 type = "aws"
 identifiers = [data.aws_iam_role.this.arn]
 }
 actions = ["secretsmanager:GetSecretValue"]
 resources = [aws_secretsmanager_secret.this.arn]
 }
}

data "aws_iam_role" "this" {
 name = "myRole"
}
`
```
What's the best way to resolve this?
```

[Assistant]
You can try to use aws_secretsmanager_secret_policy, it can create a resource policy instead of IAM policy.
Example:
```
`resource "aws_secretsmanager_secret" "example" {
 name = "example"
}

resource "aws_secretsmanager_secret_policy" "example" {
 secret_arn = aws_secretsmanager_secret.example.arn

 policy = <<POLICY
{
 "Version": "2012-10-17",
 "Statement": [
 {
 "Sid": "EnableAnotherAWSAccountToReadTheSecret",
 "Effect": "Allow",
 "Principal": {
 "AWS": "arn:aws:iam::123456789012:root"
 },
 "Action": "secretsmanager:GetSecretValue",
 "Resource": "*"
 }
 ]
}
POLICY
}
`
```
