I figured this out between these 2 solutions that just allow prometheus and grafana to be run behind a sub-path, so nginx can just pass it through normally:For prometheus, launching it with the--web.external-url=/prometheus/flag set:https://blog.cubieserver.de/2020/configure-prometheus-on-a-sub-path-behind-reverse-proxy/For Grafana, setting the server.root_url in the config:https://grafana.com/tutorials/run-grafana-behind-a-proxy/#1
|
I'm setting up an AWS instance to house both my prometheus and grafana servers. I'm using NGINX to route between the 2 clients through a /location. The problem is, NGINX has to pass this value through, and the clients can't make sense of it.My NGINX config:http {
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
server_names_hash_bucket_size 128;
types_hash_max_size 4096;
include /etc/nginx/mime.types;
default_type application/octet-stream;
# Load modular configuration files from the /etc/nginx/conf.d directory.
# See http://nginx.org/en/docs/ngx_core_module.html#include
# for more information.
include /etc/nginx/conf.d/*.conf;
server {
listen 80;
listen [::]:80;
server_name <aws instance url>;
location /grafana {
proxy_pass http://localhost:3000;
}
location /prometheus {
allow <my ip>;
deny all;
proxy_pass http://localhost:9090;
}
}
}So when I navigate to /grafana. It successfully takes me to grafana, but the grafana client attempts to parse the /grafana and can't find a page for it, and returns a 404.Is there a way to get rid of that, or am I going about this all wrong?

You need to runapt-get updatefirst to download the current state of the package repositories. Docker images do not include this to save space, and because they'd likely be outdated when you use it. If you are doing this in a Dockerfile, make sure to keep it as a singleRUNcommand so that caching of the layers doesn't cache an old version of the update command with a new package install request:RUN apt-get update \
&& DEBIAN_FRONTEND=noninteractive apt-get install -y \
net-tools \
&& apt-get clean \
&& rm -rf /var/lib/apt/lists/*

First of all the celery image is deprecated in favour of standard python image more infohere.WORKDIRsets the working directory for all the command after it is defined in the Dockerfile, which means the command which you are try to run will run from that directory. Docker image for celery sets the working directory to/home/user.Since your code is mounted on/celery_smapleand the working directory is/home/user, Celery is not able to find your python module.One alternative is to cd into the mounted directory and execute the command:celery:
image: celery:3.1.25
command: "cd /celery_sample && celery worker -A my_celery -l INFO"
volumes:
- .:/celery_sample
networks:
- webnetnotice the commandAnd another one is to create your own image withWORKDIRset to/celery_sampleeg:FROM python:3.5
RUN pip install celery==3.1.25
WORKDIR /celery_sampleafter building you own image you can use the compose file by changing theimageof celery serviceEditYou need to link the services to one another in order to communicate:version: "3"

Not a Node problem, but agitproblem. Upgraded git on Windows from 1.7.11 to 1.8.3 and the spawn worked.

This code works on Windows and on Mac OS X:var exec = require( 'child_process' ).exec
exec( 'git clone[email protected]:user/myrepo.git' )But this code returns an "Access denied(publickey)" error from git when running on Windows, but not on Mac OS X:var spawn = require( 'child_process' ).spawn
, child = spawn( 'git', [ 'clone', '[email protected]:user/myrepo.git' ], { env: process.env } )
child.on.stderr( 'data', function( data ) {
console.log( data.toString() )
})I assume inspawni'm losing my connection to~/.ssh... but I thought sending inprocess.envwould work. By the way, thegit clonecommands work fine on Windows when typed into the command prompt directly.Anything obviously wrong?

There are two things to consider here.You can adjust this rule in Sonar and increase the number of authorized parameters. Say put it 10 instead of default (?) 7.UPD: the advice below is based on the old question version. It might be not applicable to the new question context any more.But generally you should reconsider your method interface. Having many arguments means that something can be wrong in your architecture and theSingle responsibility principlemight be broken.Say in your particular example, I would expect, that you can have an aggregate classOrder:public class Order {
private CountryCode countryCode;
private String orderId;
private User user;
private String orderId;
private String item;
private List<Person> persons;
private ShippingAddress address;
private PaymentMethod payment;
private Product product;
// ...
}Which is much logical to manage instead of dealing with many parameters. Then your issues will be solved automatically:@GetMapping

I assume with malloc(sizeof(*bufferData)) you meant malloc(helloworld.length) above (since that's the only malloc call I see in your example).
The memory leak occurs when you clear your buffer:
bufferData[i] = nil;
This leaks because you allocated the buffer contents using malloc but did not free them later using free. Note that even under ARC you must free any malloced resources yourself. ARC only provides management for Objective-C object instances.
The correct way to free the buffer here is:
free(bufferData[i]);
bufferData[i] = NULL;
|
I have a problem with memory leaks when using malloc in objective c.
here's the code:
.h (interface)
{
char *buffer[6];
NSInteger fieldCount;
}
-(void)addField:(NSString *)str;
.m (implementation)
-(void)addField:(NSString *)str
{
NSString *helloworld =str;
if (bufferData[5] != nil) {
/*
clear buffer
*/
for (int i = 0; i<6; i++) {
bufferData[i] = nil;
}
fieldCount = 0;
}
bufferData[fieldCount] = malloc(helloworld.length);
char *ptrBuff = bufferData[fieldCount];
for (int i = 0; i<helloworld.length; i++) {
*ptrBuff++ = [helloworld characterAtIndex:i];
}
[self printBuffer];
fieldCount ++;
}
-(void)printBuffer
{
NSLog(@"buffer data %ld = %s",(long)fieldCount,bufferData[fieldCount]);
}
So basically I have 4 following classes below:
ViewController -> UIViewController
RootClass -> NSObject
ChildClass1 -> RootClass
Child -> Root Class
Additionally:
Init process of the three classes are inside -viewDidLoad method.
Both childClass1 and childClass 2 have a timer to call -addField method at the same time.
When I check my memory instrument, I have found a leak object every time it called
-addField method. It refers to this statement:
malloc(sizeof(*bufferData));
Can somebody help to solve my problem?

To call API usinghttpsyou need to configureSSLContextand set it to yourHttpClient. Refer below sample code. This is just the sample, you can load keystore and truststore in different way like from classpath, form file system etc.., make the changes accordingly.KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
KeyStore identity = KeyStore.getInstance(KeyStore.getDefaultType());
TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
trustManagerFactory.init(trustStore);
KeyManagerFactory keyManagerFactory = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
keyManagerFactory.init(identity, "password".toCharArray());
SSLContext sslContext = SSLContext.getInstance("TLSv1.3");
sslContext.init(
keyManagerFactory.getKeyManagers(),
trustManagerFactory.getTrustManagers(),
null
);
HttpClient httpClient = HttpClients.custom()
.setSSLContext(sslContext)
.setSSLHostnameVerifier(new DefaultHostnameVerifier())
.build();

docker compose logs has a --no-log-prefix flag that removes the prefix.
For example
# start all services in background
docker compose up -d
# show logs for all services, without prefix (-f means follow the logs)
docker compose logs -f --no-log-prefix
# or, for a single service called foo
docker compose up foo -d
docker compose logs foo -f --no-log-prefix

docker-compose inserts prefixes like service_1 | in the beginning of every line of output. I use this container for testing and this kind of improvement (very useful in other cases) mess my debugging logs and I want to remove it for this service. Documentation have no information about this question. Any ideas?

Which of the following de-allocation strategies creates a memory leakage?
In my pedantic opinion the correct answer would have to be option A, it creates a memory leak because it deallocates mptr, making mptr[i] pointers inaccessible. They cannot be deallocated afterwards, assuming that the memory is completely inaccessible by other means.
Option B does not lead to memory leak per se, mptr is still accessible after you free mptr[i] pointers. You can reuse it or deallocate it later. Memory leak would only occur if and when you loose access to the memory pointed by mptr.
I believe the question is somewhat ill-formed, if the question was "Which option would you use to correctly deallocate all the memory?", then yes, option C would be correct.
I do agree that the correct strategy to deallocate all the memory is B + A, albeit A first will cause immediate memory leak whereas mptr0 first will allow for later deallocation of mptr1, as long as the access to the memory pointed by it is not lost.
I don't see the point of this code, if you already have allocated memory with calloc (and initialized it) why would you go as far as to allocate each cell with a cycle? Am I wrong to believe that?
The allocation is correct.
mptr2
Check this thread for more info.
|
In a recent exam question I got this code with following options:
char **mptr, *pt1;
int i;
mptr = calloc(10, sizeof(char*));
for (i=0; i<10; i++)
{
mptr[i] = ( char *)malloc(10);
}
Which of the following de-allocation strategies creates a memory leakage?
A. free(mptr);
B. for(i = 0; i < 10; i++): { free(mptr[i]); }
C. All of them
The answer is C. But it seems to me that applying free(mptr); would suffice covering the memory leak, and B as well, although I'm less sure of that, can someone explain me why all of them would cause a memory leak?
I'm guessing the C options expects that each operation ( A or B ) are applied separatly.
P.S.
I don't see the point of this code, if you already have allocated memory with calloc (and initialized it) why would you go as far as to allocate each cell with a cycle? Am I wrong to believe that?

Allocating a pointer with calloc, and then dynamically allocate each cell with malloc = memory leakage?

I agree with @rubenvb that you're going to have to clone the repo and do the count locally. I don't know a tool which will get the number of files for each revision, so you're going to have to roll your own.To get the count at the current checked-out commit, you could rungit ls-files | wc -lwhich will give you a total for the repo at that commit.To get the all-time count, you'd need to loop over all the commits reachable from the first commit, running that command each time. You might try pushing the output ofgit ls-filesinto an array each time, and maintain a "global" array while looping through all commits. (This is likely to take some time on a big repo like jQuery.) Then you can count the size of the array afterward.The number is going to be pretty subjective depending on what you decide to count, though. Should you count a file which moves from one directory to another in a commit? (In the method I've just outlined, it will be counted as two different files.) Do you count branches which haven't been merged to master, or just any commit reachable from the HEAD of the current master branch? That's up to you.

You could do this with bash only. No need for php:find /your/directory -type f -mmin +720 -exec rm {} \;--mmin parameter is file age in minutesIf you are on a shared server you could still try to execute this with shell_exec(), most hosters allow thisAlso you forgot to skip '.' and '..' in the loop

I have looked around this site and others to find a simple php script that I can use with cron to remove files over X days old in a directory. There seem to be plenty but none work for me. I am on a shared server (G C Solutions) and the hosters are great but the packageI am on does not include shell access so I don't think I can use .sh or bash commands.I have a neat php script to do a Mysqldump of my database, copy it to a directory in my home area ( /home/mysite/backups ) and send me a copy via email - this all works fine. Now I was trying to run a script that would just leave 5 days worth of backups in the backups diretory. I am trying this script at present:-<?php
$dir = opendir('/home/mysite/backups");
if ($dir) {
// Read directory contents
while (false !== ($file = readdir($dir))) {
// Check the create time of each file (older than 5 days)
if (filemtime($file) < (time() - 60*60*24*5)) {
unlink($file);
}
}
}
?>It doesn't work, my cron setting string is :-
php -q /home/mysite/public_html/scripts/delold6.phpI've tried running it from above the the html_public, no joy, the backup directory rights are set to 755, when my backup script copies the dump to this directory files are set at 644. I have tried chmoding these to 777 - no joy. Can anyone help here. *find /path/to/your_directory -mtime +5 -exec rm -f {} \;* does not work from cron either.

For anyone stumbling across this, it seems that certain v2 versions (2.2.7 in my case) fail silently if less isn't installed.
In these cases, setting AWS_PAGER to an empty string should fix the problem.
Later AWS CLI versions (e.g. 2.2.18) are decidedly more helpful:
aws sts get-caller-identity
Unable to redirect output to pager. Received the following error when opening pager:
[Errno 2] No such file or directory: 'less'
Learn more about configuring the output pager by running "aws help config-vars".

I've been using aws cli on this laptop for a while to interact with s3 buckets. Suddenly, the tool has stopping printing any output whatsoever:

C:\>aws --debug
C:\>aws --help
C:\>where aws
C:\Users\Andrew\AppData\Roaming\Python\Python37\Scripts\aws
C:\Users\Andrew\AppData\Roaming\Python\Python37\Scripts\aws.cmd
This is in an administrator command prompt, but it's the same in an admin powershell prompt. Windows version 10.0.18362 Build 18362 - I took the anniversary update a few weeks ago but am not sure if it's correlated or not.
aws cli on my other (Win 10, anniversary update) machine, using the same authentication, works fine.
I've tried straight-up uninstalling and reinstalling aws cli, but after the reinstall I can't even get it to print anything to authenticate me.
Any ideas? Any more information I can give you?

Verified means the commit was signed with a GPG key known to Github. To "verify" commits you need to sign them and the only way to do that is to do interactive rebase during which sign every commit. All rebased commits will be changed so you have to force-push the branch.

I know what means 'verify', but you didn't answer my question. If I will rebase everything, so every commit will be signed, will they be 'on the same place' (same timestamp/date etc.) or these will be counted as new commits?

I have some unverified commits here: https://github.com/DeBos99/portable-strlen/commits/master
Is there any way to verify this commits and keep them at the end of the list of commits?

I think you still have all the repository remotes locally configured.Try in the repo folder to see the remote repositories :git remote -vAnd delete the remote with :git remote rm <remote-name>

We've upgraded our SonarQube server from 6.1 to 6.5 version and post upgrade we aren't able to see the administration options for any of the projects as earlier. We see only few options enabled "Quality Profile & Quality Gate". However, we can browse to each of the tabs by creating urls in the browser. Its just that the UI doesn't show these options.Can someone let us know what could've gone wrong and help us resolve this issue.This would play a major role in helping the customers in managing their projects.

There is no pixie dust.You need to write your code very carefully, in a cache friendly manner. Have a look atCPU Caches and Why You Care, absolutely positively get a copy ofThe Software Optimization Cookbookand read it carefully end-to-end.As a side, OS platforms allow for process memory to be pinned (not swappable, which is a differnet topic from L2 code/data caching, but you're quite far from proving that L2 cache is the culprit in your case anyway...) but 101% cases the OS knows better than your app and preventing it from swapping results in worse performance, not better.

I have a program composed of two parts:a virtual machine of a graphical programming language,image processing routines.The problem is that the virtual machine works fast enough as long as there are no big images processed. The drop of the performace of the virtual machine is about the factor of 5 after processing of a big image. I guess this is because memory buffers of the objects belonging to the virtual machine get removed from cache when a big image comes. Normally, a processor keeps a separate cache for code, separate for data, but not when my program is interpreted.QUESTION:
Is there any way to make it the same for interpreted code, i.e. to mark somehow a memory buffer as high-priority for cache memory, or to allocate somehow a memory buffer that will be guaranteed to stay in cache?Let me add, that although image processing is much slower than intepreting programs, there happen to be cases when the second part becomes critical - think for example of postprocessing a set of points detected on an image - these are simple arithmetical operations that are too slow on a virtual machine then.

Two paths:ConfigureNginx to serve on 443 with TLS. Configure GCP firewallto allow for httpswith tags.With tags, configure FW rules for the instance to only serve 8080 to GCP Load Balancers andhave HTTP(S) Load Balancingserve the content via TLS to the public.In any case you'll have annoying TLS issues without a DNS name - so you should get one.

I have nginix+django server on google cloud virtual machine which is running at a specific port(8080). I am able to access the service byhttp://external_ip:8080. But I'm not able to access it over "https". I dont have a domain name. For our application it is not necessary as it is just a rest api to perform some tasks.

Using a named volume (or more specifically a volume created using the Docker Engine volume API) with a defined host path doesn't have much of an advantage over the method you've used. Technically, it is "easier" to create a new container, but only because you no longer have to remember the path. You can also use the volume API to "manage" the volume independently from the application container, but this is equally easy using the docker container API.If you insist, to create a named volume with an absolute host path, you need to use a volume-driver. I would suggest local-persist. It is quite simple to install and works well.https://github.com/CWSpear/local-persistShareFollowansweredJan 3, 2017 at 16:39James MoserJames Moser49622 silver badges66 bronze badgesAdd a comment|

You can't specify the SerDe in the Glue Crawler at this time but here is a workaround...Create a Glue Crawler with the following configuration.Enable 'Add new columns only’ - This adds new columns as they are discovered, but doesn't remove or change the type of existing columns in the Data CatalogEnable 'Update all new and existing partitions with metadata from the table’ - this option inherits metadata properties such as their classification, input format, output format, SerDe information, and schema from their parent table. Any changes to these properties in a table are propagated to its partitions.Run the crawler to create the table, it will create a table with "org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe" - Edit this to the "org.apache.hadoop.hive.serde2.OpenCSVSerde".Re-run the crawler.In case a new partition is added on crawler re-run, it will also be created with “org.apache.hadoop.hive.serde2.OpenCSVSerde”.You should now have a table that is set to org.apache.hadoop.hive.serde2.OpenCSVSerde and does not reset.
|
Every time I run a glue crawler on existing data, it changes the Serde serialization lib toLazySimpleSerDe, which doesn't classify correctly (e.g. for quoted fields with commas in)I then need to manually edit the table details in the Glue Catalog to change it toorg.apache.hadoop.hive.serde2.OpenCSVSerde.I've tried making my own csv Classifier but that doesn't help.How do I get the crawler to specify a particular serialization lib for the tables produced or updated?

In Git, changes are done locally and then must be pushed to the remote. This lets you do your work locally before deciding it is ready to share it with others.
git flow release finish will finish your release locally. You then have to push your finished release. git flow does not do this push for you.
The docs have an example...
Finishing a release is as simple as:
$ git flow release finish 1.4.0
This will:
Merge changes into the master branch,
Create a 1.4.0 tag,
Merge changes into the develop branch,
Remove your local release\1.4.0 branch.
Once your release has been finished; you’ll have to push master, develop and tags and also remove remote release/1.4.0 branch (if any):
(master) $ git push
(master) $ git push --tags
(master) $ git checkout develop
(develop) $ git push
$ git push {github_username} :release/1.4.0
|
Initially I am cloning a Git repo to my local and then doing:
git flow init .
I am able to successfully create feature branch and merge to develop by creating pull request.
Now I use:
git flow release start <branch_name>
and push the release branch to remote.
Changes are fine so I do:
git flow release finish <branch_name> .
It executes fine on local and code is merged to develop and master branch, tag is cut and release branch is deleted, but on remote repo changes are not automatically merged to master branch but are back merged to develop branch only.
What is the possible issue it did not merge into master branch of remote repo?
|
`git flow release finish` does not merge code in `master` branch on remote repo

Git is fast enough.If you want them in your repository - you will have to add, commit and push them once. If they don't change, they will never again be transferred and will NOT influence the pull and, moreover, merge time.It is because git stores snapshots of files and not their diffs.Say, you've got a file. It has sha1 ofabcdef123456. Imagine a conversation between local and remote repos:First push:Local: "I've got abcdef123456 here!"Remote: "Please transfer it to me"Next pushesLocal: "I've got abcdef123456 here!"Remote: "Heh, that's boring. I've got it already."

I am currently working on a project that has a directory with a lot of small files within it that don't change. I know that I can add it to the git ignore but I still want them in my repo. Will zipping the directory shorten the time it takes to pull/merge and if so are there any other ways to shorten the process?

As i know there is two metrics which allow you to monitor OOM.
The first one is used for tracking OOMKilled status of your main process/pid. If it breach the limit pod will be restarted with this status.
kube_pod_container_status_last_terminated_reason{reason="OOMKilled"}
And the second one for gathering total count of OOM events inside the container. So every time some child process or other process will breach the RAM limit they will be just killed and metric counter increased. But the container will be working as usual.
container_oom_events_total

I have a spark executor pod, which when goes to OOMKilled status, I want to alert it. I am exporting spark metrics using prometheus to grafana.
I have tried some queries to
kube_pod_container_status_last_terminated_reason{reason="OOMKilled"}
kube_pod_container_status_terminated_reason{reason="OOMKilled"}
They don't seem to give proper results. I am cross checking the result using humio logs, which is logging the OOMKilled properly.
container_memory_failures_total{pod="<<pod_name>>"}
Even this is not able to capture the problems of OOMKilled which is in sync with the humio logs. Is there any other proper metric to catch OOMKilled ?

You can useRESTORE FILELISTONLY FROM DISK = N'C:\Path\YourBackup.bak'to check the space used by the DB in the backup upon restoration. Basically, this will allow you to see how big it'll be, without actually restoring the backup.

It depends on your definition of "last".
for a given branch (like master), GET /repos/:owner/:repo/commits/master is indeed the last (most recent) commit.
But you can also consider the last push event: that would represent the last and most recent commit done (on any branch), pushed by a user to this repo.
|
Which is the best way to get the latest commit information from a git repository using GitHub API (Rest API v3).
Option 1: GET /repos/:owner/:repo/commits/master
Can I assume that the object 'commit' of the response is the latest commit from branch master?
Option 2: GET /repos/:owner/:repo/git/commits/5a2ff
Or make two calls, one to get the sha by getting the HEAD ref from master and then get the commit information using the sha returned.

You can build onshaunc's idea to use thelookupfunction to fix the original poster's code like this:apiVersion: v1
kind: Secret
metadata:
name: db-details
data:
{{- if .Release.IsInstall }}
db-password: {{ randAlphaNum 20 | b64enc }}
{{ else }}
# `index` function is necessary because the property name contains a dash.
# Otherwise (...).data.db_password would have worked too.
db-password: {{ index (lookup "v1" "Secret" .Release.Namespace "db-details").data "db-password" }}
{{ end }}Only creating theSecretwhen it doesn't yet exist won't work because Helm will delete objects that are no longer defined during the upgrade.Using an annotation to keep the object around has the disadvantage that it will not be deleted when you delete the release withhelm delete ....
|
I want to generate a password in a Helm template, this is easy to do using therandAlphaNumfunction. However the password will be changed when the release is upgraded. Is there a way to check if a password was previously generated and then use the existing value? Something like this:apiVersion: v1
kind: Secret
metadata:
name: db-details
data:
{{ if .Secrets.db-details.db-password }}
db-password: {{ .Secrets.db-details.db-password | b64enc }}
{{ else }}
db-password: {{ randAlphaNum 20 | b64enc }}

Let's say you are starting a new repository. You'd have to start local first, right? So,
git init -> Initializes a repository on your local computer. (assuming you started with an empty folder)
Now you have an empty repository. Now it's time to add lots and lots of awesome code/content. Once you have some code, you will commit.
git commit -> Git will still keep all your changes locally; but remembers all the changes you made in this commit.
Let's say you make a couple of more changes, and want to save your work. So, you'll run the commit again. Git again saves your changes, but in commit #2, still local to your computer.
Now you are ready to share your work with other people. Because Github repo's are online (typically), you will have to push (i.e. upload) your changes to a remote repository.
Difference between commit and push is, the first one keeps all your changes locally on your computer (no one else in your team has access to your changes or commits), and push will make your code available to everyone. Hope that's clear!

I'm using github to work on a project with two other people and am getting very confused about the whole commit thing, and nothing I'm reading is helping me understand. I get that commit records changes that you've made to a local repository... but then why are my group members' commits showing up on the online repository? Can you commit to both the local repository on your computer as well as an online repository? If you can commit to an online repository, what is the difference between doing that and simply using git push to push your changes online?
Thank you kindly.

Create a record set with these values:

Type: A - IPv4 address
Alias: Yes
Alias Target: [click and choose your elastic load balancer]
Alias Hosted Zone ID: [auto fills in when you choose the above, you can match this to your logs]

Theofficial recommendationis to ignorevendor/:Tip:If you are using git for your project, you probably want to addvendorinto your.gitignore. You really don't want to add all of that code to your repository.Make sure to include both yourcomposer.jsonandcomposer.lockfiles, though.
|
I want to use the autoloader generated by composer for my unit tests to load classes automatically.Now I don't know if I should commit my vendor directory to my git repo. A pro is that everyone who clones my repo immediately can run the phpUnit tests. A con is that I ship a lot of proprietary code with my repo.Should I insist that the user who clones my repo has to runcomposer installfirst and therefor has to have composer "installed"?Is it a solution to don't commit vendor directory into my git repo but pack it into a release branch so that my application runs out of the box?

The two options are not so different after all. The only difference is that in option 2, you only have one copy of the code on your disk.In any case, you still need to run different worker processes for each instance, as Redmine (and generally most Rails apps) doesn't support database switching for each request and some data regarding a certain environment are cached in process.Given that, there is not really much incentive to share even the codebase as it would require certain monkey patches and symlink-magic to allow the proper initialization for the intentional configuration differences (database and email configuration, paths to uploaded files, ...). The Debian package does that but it's (in my eyes) rather brittle and leads to a rather non-standard system.But to stress again: even if you share the same code on the disk between instances, you can't share the running worker processes.
|
I'm studying the best way to have multiple redmine instances in the same server (basically I need a database for each redmine group).Until now I have 2 options:Deploy a redmine instance for each groupDeploy one redmine instance with multiple databaseI really don't know what is the best practice in this situation, I've seen some people doing this in both ways.I've tested the deployment of multiple redmines (3 instances) with nginx and passenger. It worked well but I think with a lot of instances it may not be feasible. Each app needs around 100mb of RAM, and with the increasing of requests it tends to allocate more processes to the app. This scenario seems bad if we had a lot of instances.The option 2 seems reasonable, I think I can implement that with rails environments. But I think that there are some security problems related with sessions (I think a user of site A is allowed to make actions on site B after an authentication in A).There are any good practice for this situation? What's the best practice to take in this situation?Other requirement related with this is: we must be able to create or shut down a redmine instance without interrupt the others (e.g. we should avoid server restarts..).Thanks for any advice and sorry for my english!Edit:My solution:
I used a redmine instance for each group. I used nginx+unicorn to manage each instance independently (because passenger didn't allow me to manage each instance independently).

I've setup a localstack install based off the article How to fake AWS locally with LocalStack. I've tested copying a file up to the mocked S3 service and it works great.
I started looking for the test file I uploaded. I see there's an encoded version of the file I uploaded inside .localstack/data/s3_api_calls.json, but I can't find it anywhere else.
Given: DATA_DIR=/tmp/localstack/data I was expecting to find it there, but it's not.
It's not critical that I have access to it directly on the file system, but it would be nice.
My question is: Is there anywhere/way to see files that are uploaded to the localstack's mock S3 service?

See the code ofdocker start:Ln99: resp, errAttach := dockerCli.Client().ContainerAttach(ctx, c.ID, options)
Ln136: dockerCli.Client().ContainerStart(ctx, c.ID, startOptions)docker startconsists separateattach&startoperation, if the container already start, just skip thisstartoperation, butattachstill works there.So, they are same in this scenario. BTW, from October 2014, docker team suggest to usedocker execto enter the container.
|
The Docker documentation indicates thedocker attachcommand is used to attach to arunningcontainer (atdocker container attach) and thedocker startcommand is used to startstoppedcontainers (atdocker container start).However, I tried applyingdocker start -aito arunningcontainer, and it looks that it can successfully attach to the running container.So my question is"Aredocker start -aianddocker attachthe same when they are used to attach to a running container?".

Since there isn't malloc in opencl device and also structs are used in buffers as an array of structs, you could add index of it so it knows where it remains in the array. You can allocate a big buffer prior to kernel, then use atomic functions to increment fake malloc pointer as if it is allocating from the buffer but simply returning an integer that points to last "allocated" struct index. Then, host side would just use the index instead of pointer.If struct alignments become an issue between host an device, you can add indexing of fields too. Such as starting byte of a field A, starting byte of a field B, all compacted in a single 4-byte integer for a struct having 4 used fields except indexes.Maybe you can add a preprocess stage:host writes an artificial number to a field such as 3.1415device checks floating points in struct for all byte offsets until it finds 3.1415device puts the found byte offset to an array and sends it to hostthen host writes float fields in a struct starting from that byte offsetso host and device become alignment compatible, uses same offset in all kernels that get a struct from hostmaybe opposite is betterdevice puts 3.14 in a field of structdevice writes the struct to an array of structhost gets the bufferhost checks for 3.14 and finds byte offsethost writes and fp number starting from that offset for future workwhich would need both your class and its replicated struct on host+device side.You should also look for "sycl api".

I have an OpenCL C++ code working on the Intel Platform. I do have an idea that pointers are not accepted within a structure on the Kernel End. However, I have a Class which utilizes the Self-Referencing Pointer option within it. Now, I am able to use a structure and replicate the same for the structure on the host side but I am not able to do the same on the device side.For example as follows:Class Classname{
Classname *SameClass_Selfreferencingpointer;
}
On the Host side I have done the same for the structure as well:
struct Structurename{
Structurename *SameStructure_Selfreferencingpointer;
}Could someone give an alternate option for this implementation for the device side?Thank you for any help in advance.

If you have the login (username) of the user/group, you can useorganization&userto search respectively an organization & a user and check which of the 2 fields is notnull:{
org: organization(login: "google") {
name
members {

}
}
user: user(login: "google") {

}
}which gives :{

}or using a variable forlogininput,try it in the explorerFor the Rest API v3, it's much simpler since it doesn't distinguish the user from the organization :https://developer.github.com/v3/users:curl -s 'https://api.github.com/users/google' | jq -r '.type'Organizationcurl -s 'https://api.github.com/users/torvalds' | jq -r '.type'User

In your instance it sounds like you should have a single inbound rule for the security group assigned to your ElastiCache Redis cluster. This rule for port 6379 should specify the security group assigned to your EC2 instance(s) in the "source" field.
By specifying the security group ID in the source field, instead of an IP address or IP range, you can easily scale-out your EC2 server cluster, or make modifications to your EC2 instance that might result in an IP address change, without needing to change the security group rules for your ElastiCache cluster.
Note that if you do continue using IP addresses in your security group, you need to use the Private IP of the EC2 server, not the Public IP.
|
I want to create a security group for AWS Elasticache (Redis).
As far as i see, i have 2 options:
Either open a Custom TCP connection on port 6379, and define the IP addresses what can reach Redis as a source.
Or, what currently works: I Open the 6379 port to anywhere (so that my EC2 instance can connect to it), and secure the components before the EC2.
What is the best approach here?

The code says:// if there are any entries in numlist
if (numlist.Any())
{
// find the first entry whose Number matches the request,
// or if not found, return the default for the numlist's
// type, which is null according to the warning
numlist.FirstOrDefault(c => c.Number == request.Number)
// set the ValCount property of the result to request.Count
.ValCount = request.Count;
}The problem is thatFirstOrDefault(predicate)returns a default value if none of the elements in the source collection matched the predicate.In other words: it's not guaranteed that there's any entry innumlistthat hasNumber == request.Number, in which caseFirstOrDefault()will returnnull.You can't assignValCountonnull, that will throw a NullReferenceException.Furthermore, combiningAny()andFirstOrDefault()is superfluous in this case. You can refactor the code like this:var requestedItem = numlist.FirstOrDefault(c => c.Number == request.Number);
if (requestedItem == null)
{
throw new ArgumentException($"Cannot find item with number '{request.Number}'");
}
requestedItem.ValCount = request.Count;Guarding execution (and at the same time pleasing the static analysis), guaranteeing that a situation which you think might never happen, will never happen.

As OpenStack uses VXLAN tunnels for communication. VXLAN tunnel has 50 bytes reserved for the headers. Suppose host machine NIC has MTU of 1500 then OpenStack VMs will have MTU of 1450. So ideally docker bridge should have MTU size <= 1450.

@application.route('/')

Here is a graph of the memory usage, usingAmazon's memory monitoring scripts:You can see the little dip where (I assume) garbage collection happened on 1/29. But what on earth is allocating so much memory? If this is normal, how should I be monitoring memory so I can actually figure out if my (real) application has a memory leak?

$argv[0]always contains the name of the script file, as it passed to the PHP binary.
As per screenshot,$argv[1]is '33' and$argv[2]is 'On'. You can easily check with:echo $argv[1];Or you can list all arguments as an array by:var_dump($argv);Basically, the following task is added to crontab, when scheduled via Plesk:/usr/bin/php5 -f '/test.php' -- '33' 'On'Iftest.phpcontains mentioned commands, the result of its' execution will be the following:# cat /test.php
<?php
echo "The first argument is $argv[1]\n";
echo "Here the full list of arguments:\n";
var_dump($argv);
?>
# /usr/bin/php5 -f '/test.php' -- '33' 'On'
The first argument is 33
Here the full list of arguments:
array(3) {
[0]=>
string(6) "/test.php"
[1]=>
string(2) "33"

I have created a Cron Job/Scheduled Task in PLESK 12 which I am passing the arguments 33 and On through using the arguments box.

The question I have is, what if the work I'm doing in my new feature
branch depends on the work I just completed in my previous feature
branch? Should I be initially branching my new feature branch from my
as-of-yet unmerged feature branch instead of the develop branch?
The way you're describing it, yes, you would. However, I'd be concerned about potentially going down the path of working off of "unapproved / unreviewed" work, as if your code review results in significant changes, you may find yourself redoing a lot of work.
If I've already created my new feature branch from the develop branch,
is getting the changes I'm missing from the unmerged branch as simple
as doing a git merge [unmerged-branch] within my new branch?
Yep. Should be. :)
|
My company has a Git workflow that looks something like this:
Create feature branch from pristine branch (we use a base branch called "develop", but you can think of this as "master")
Do the work you need to do in this feature branch, and commit your changes
Occasionally, rebase your feature branch with the develop branch
When the work in your feature branch is complete, commit and push to the remote feature branch on GitHub
Create a pull request to merge your feature branch into the develop branch, which gets code reviewed by another developer
Once the code review is completed, the feature branch is merged into the develop branch, and the feature branch is deleted
This works when you're dealing with a serial workflow, but when you've pushed your changes from your feature branch and are waiting on the other developer to review and merge your changes, you probably want to take on another piece of work, which means repeating the above process.
In our case, we're currently creating our feature branches from the develop branch, so the work I just completed isn't yet available (it's still in limbo, waiting to be merged into the develop branch by another developer). The question I have is, what if the work I'm doing in my new feature branch depends on the work I just completed in my previous feature branch? Should I be initially branching my new feature branch from my as-of-yet unmerged feature branch instead of the develop branch? If I've already created my new feature branch from the develop branch, is getting the changes I'm missing from the unmerged branch as simple as doing a git merge [unmerged-branch] within my new branch?
Hopefully this explanation -- as well as the workflow itself! -- makes sense. I've gotten myself into some weird situations where I'm unclear the state of my code, so I'm trying to figure out a workflow that gives me the flexibility to merge in changes from other feature branches while still getting upstream changes at any time.

The FAQ just says that cpython itself does not actively deallocate all the memory it has acquired when it terminates
If you run cpython on a any normal server/desktop OS that releases all memory of a process when it exits, then there's no issue with memory leaks. The OS takes care of deallocating all memory when the process has exited.
The FAQ is more to inform you that cpython does not call free() or similar on all the memory it has allocated with malloc() or similar. This can have consequences if you run cpython on an OS that does not release all memory acquired by the process when the process exits (These operating systems exists, it is in particular the case with many embedded kernels). And if you run cpython under a memory profiler/leak detector, that detector might report the memory not free()'d as leaks.

I want to be clear, I am not seeing the behavior described by this question. Instead my question is about the question itself:
The python 3 official FAQ says this verbatim:
Why isn't all memory freed when CPython exits?
And provides this answer:
Objects referenced from the global namespaces of Python modules are
not always deallocated when Python exits. This may happen if there are
circular references. There are also certain bits of memory that are
allocated by the C library that are impossible to free (e.g. a tool
like Purify will complain about these). Python is, however, aggressive
about cleaning up memory on exit and does try to destroy every single
object.
If you want to force Python to delete certain things on deallocation
use the atexit module to run a function that will force those
deletions.
This, assuming a managed memory operating system (Linux, Mac, Windows, GNU, BSD, Solaris...), sounds like total nonsense.
On a program exiting (be it Python or anything else) any memory it requested from the OS is freed (as the OS has control of the virtual page tables, etc, etc). The program doesn't have to de-allocate or de-construct anything (something programs used to have to do, as highlighted by the time someone's use of cp got bottlenecked by a hash table deconstruction), but I don't think any OS' Python 3 supports puts this requirement on programs.
Does this make sense in some context I'm not aware of? What is this referring to?

This is the way ContainerOverrides work, contrary to what it should work like. You have two options to solve this:
Create a Lambda Function that starts the State Machine.
Invoke the Lambda Function when you want to invoke the State Machine.
That Lambda function will call the describe_task_definition ECS SDK function to get the complete details of your task definition and while calling start_execution function for step functions, pass all the content of Parameters along with the new/updated environment variables.
The Lambda function can be scheduled or run on demand.
List all the Environment Variables in the State Machine.
Just like you mentioned the new variable, you may mention all the previous variables as well. (It has a disadvantage of redundancy)
You may use SSM parameter store for all your variables and then mention all the paths in your State Machine Task definition as well.
First option will need some custom implementation, but will save you from manual configurations.

I'm using an AWS Step Function to invoke a Fargate container. The ECS Task Definition has several environment variables defined, some with fixed values and some coming from Systems Manager Parameter Store. The State Machine adds one additional environment variable using ContainerOverrides.
Unfortunately this seems to replace, not add to, the environment variables specified within the task definition.
If I don't define any environment variables in the step definition, then those from the task definition exist at runtime. If I define even one variable at the step definition, then only those from the step definition exist at runtime.
How can I get Fargate/ECS/Step Functions to merge the environment variable instead of replacing all?

You shouldn't be deciding whether or not to use static fields/methods based on memory consumption (which likely won't be altered much). Instead, you should go with what produces cleaner, more testable code.Staticmethodsare okay (IMO) if you don't need any kind of polymorphic behaviour, and if the method doesn't logically act on an instance of the type. However, if you'vealsogot static variables involved, that's more of an issue. Static variables - other than constants - can make code much harder to test, reuse, and handle correctly in multiple threads.It sounds like you probablyshouldbe using instance variables and methods. Just make yourMainmethod create an instance of the class, and it can use that instance to create delegates to pass to the timer. It's hard to be much more precise than that without knowing more about what you're doing, but it does sound like you're using statics for immediate convenience rather than because it's the right thing to do, which is always a worry.ShareFollowansweredJun 14, 2012 at 6:11Jon SkeetJon Skeet1.5m876876 gold badges9.2k9.2k silver badges9.2k9.2k bronze badges2Thanks for your answer.

Now I have taken all other methods/variables static because that are calling from timer handler events (which are static due to calling it from main).Now i would like to know for above scenario how memory is going to be consumed if this console running for long time? if i would like to apply oops concept then do i need make all methods/variables non static and access that by creating object of class? in this case how memory going to be consume?Update:Following is snippet of my codepublic class Program

I faced the same issue. The following fixed it for me:
Change your Amazon email address on www.amazon.com - You can use the same email address by using this trick. Change [email protected] to [email protected]
Use the lost password recovery on the AWS login site to recover the password for the former email address (i.e. [email protected]).
Use the new password to login on the AWS console with the former email address ([email protected])

Issue: I am trying to sign in as a root user for my account from the AWS portal, but now, after I adding my password I keep getting redirected to:
https://portal.aws.amazon.com/billing/signup?redirect_url=https%3A%2F%2Faws.amazon.com%2Fregistration-confirmation#/start, no matter what.
It was working fine till today, first time I've encountered this redirect.
Main Browser : Chrome - Version 62.0.3202.94
Based on what on similar cases found on google I tried the following and still did not manage to sort out the issue:
-Chrome: deleted all the cookies and cache data
-Chrome: restarted the device and also the browser
-Chrome: used incognito mode
-Firefox (an aws member said is the most suitable browser): tried normal and private mode
-Firefox: deleted all the cookies and cache data
-Edge: tried normal and private mode
Someone suggested already to make use of S3Browser, it does not seem as a efficient solution just to access the AWS Portal a few times a week so I am keeping it as the last resort.
If anyone experienced the same issue or has any more suggestions/ideas would greatly appreciate some help.
Thanks in advance.

If you're talking about gigabytes of data, you might consider loading and plotting the data points in batches, then layering the image data of each rendered plot over the previous one. Here is a quick example, with comments inline:import Image
import matplotlib.pyplot as plt
import numpy
N = 20
size = 4
x_data = y_data = range(N)
fig = plt.figure()
prev = None
for n in range(0, N, size):
# clear figure
plt.clf()
# set axes background transparent for plots n > 0
if n:
fig.patch.set_alpha(0.0)
axes = plt.axes()
axes.patch.set_alpha(0.0)
plt.axis([0, N, 0, N])
# here you'd read the next x/y values from disk into memory and plot
# them. simulated by grabbing batches from the arrays.
x = x_data[n:n+size]
y = y_data[n:n+size]
ax = plt.plot(x, y, 'ro')
del x, y
# render the points
plt.draw()
# now composite the current image over the previous image
w, h = fig.canvas.get_width_height()
buf = numpy.fromstring(fig.canvas.tostring_argb(), dtype=numpy.uint8)
buf.shape = (w, h, 4)
# roll alpha channel to create RGBA
buf = numpy.roll(buf, 3, axis=2)
w, h, _ = buf.shape
img = Image.fromstring("RGBA", (w, h), buf.tostring())
if prev:
# overlay current plot on previous one
prev.paste(img)

prev = img
# save the final image

I'm doing a rather large PyPlot (Python matplotlib) (600000 values, each 32bit). Practically I guess I could simply do something like this:import matplotlib.pyplot as plt
plt.plot([1,2,3,4], [1,4,9,16], 'ro')
plt.axis([0, 6, 0, 20])Two arrays, both allocated in memory. However I'll have to plot files, which contain several Gigabyte of those information sooner or later.How do I avoid passing two arrays into theplt.plot()?I still need a complete plot however. So just an Iterator and passing the values line by line can't be done I suppose.

Any data set that is defined and doesn't change is best!Memory mapped files generally win over anthing else - most OSs will cache the accesses in RAM anyway.
And the performance will be predictable, you don't fall off a cliff when you start to swap.
|
I have a service that is responsible for collecting a constantly updating stream of data off the network. The intent is that the entire data set must be available for use (read only) at any time. This means that the newest data message that arrives to the oldest should be accessible to client code.The current plan is to use a memory mapped file on Windows. Primarily because the data set is enormous, spanning tens of GiB. There is no way to know which part of the data will be needed, but when its needed, the client might need to jump around at will.Memory mapped files fit the bill. However I have seen it said (written) that they are best for data sets that are already defined, and not constantly changing. Is this true? Can the scenario that I described above work reasonably well with memory mapped files?Or am I better off keeping a memory mapped file for all the data up to some number of MB of recent data, so that the memory mapped file holds almost 99% of the history of the incoming data, but I store the most recent, say 100MB in a separate memory buffer. Every time this buffer becomes full, I move it to the memory mapped file and then clear it.

Are memory mapped files bad for constantly changing data?

The setup is different for domains like example.com and sub-domains like blog.example.com.
In case of a sub-domain: blog.example.com
Go to Domains | Manage Domains in your webpanel
Locate blog.example.com, click Delete in the Actions column
Wait 10 minutes, and then click the DNS link below example.com
Add a CNAME record:
Name = blog
Type = CNAME
Value = yourusername.github.io. (yes there is a . at the end!)
In case of a domain: example.com
Go to Domains | Manage Domains in your webpanel
Locate example.com, click Edit in the Actions column and switch to DNS only hosting (it's at the bottom)
Go back to Domains | Manage Domains in your webpanel
Click the DNS link below blog.example.com0
Add an blog.example.com1 record:
Name = (blank, nothing)
Type = blog.example.com2
Value = blog.example.com3 (GitHub, from this page)
Add a blog.example.com4 record:
Name = blog.example.com5
Type = blog.example.com6
Value = blog.example.com7 (yes there is a blog.example.com8 at the end!)
(Yes, you need both the blog.example.com9 and blog.example.com0 records in this case.)
Btw, the only reason I know this is because I did the same thing last weekend. I was quite lost, but the helpful support guys helped me half way, and I figured out the rest. This procedure works for me, I needed both cases so I tested both.

I created a Jekyll-powered blog and am hosting it with GitHub Pages.
Now, I want to set up a subdomain (blog.example.com), but can't make it work.
I have added a CNAME file with the text: blog.example.com. And I have added two A records in my Dreamhost account for the subdomain, both pointing to 204.232.175.78, provided by GitHub.
Any idea about what the missing part is, or if I'm doing something incorrectly?

You're forward everything to PHP FPM, meanwhile, by default in PHP-FPM process config file, it only allows .php file to be served.
You can check in /usr/local/etc/php-fpm.d/www.conf inside php-fpm container, and search for security.limit_extensions, you'll see.
So here you have 2 solutions
Solution 1: map your project source into container where you're running Nginx, like this:
# docker-compose.yml
webserver:
image: nginx:1.17-alpine
restart: unless-stopped
ports:
- "8000:80"
volumes:
- ./:/var/www/html
By doing this Nginx can easily find your static files and serve them. Note that /var/www/html is your root project path which you defined in your Nginx config file. For example, Nginx config file for Laravel project usually looks like:
server {
listen 80;
index index.php index.html;
root /var/www/html/public;
...
Solution 2: add .css, .js to PHP-FPM process config file, with this solution, you'll override PHP-FPM config file and add your static files to list file extensions that PHP-FPM allows. Check my demo here. This solution won't require you to map your project into Nginx container. But in reality it's not good for production like solution 1

Working solution for this :) The only drawback for this is that need to define all the extensions which required from your web server. Will be even better if it can do the auto forwarding for content-type.

I am running NGINX, PHP-FPM and DB in separate container.
Inside PHP-FPM is mounting a Laravel project from my local machine.
I've successfully forward the PHP request to PHP-FPM container (port 9000) while accessing 127.0.0.1:8000. Unfortunately, the requests with assets extension (e.g. .css, .js) has ran into 403 forbidden.
Following are my NGINX configuration script.
server {
listen 80;
add_header X-Frame-Options "SAMEORIGIN";
add_header X-XSS-Protection "1; mode=block";
add_header X-Content-Type-Options "nosniff";

}
location = /favicon.ico { access_log off; log_not_found off; }
location = /robots.txt { access_log off; log_not_found off; }
error_page 404 /index.php;
location ~ \.php$ {

}
}

Not sure if anyone has ran into similar problems and have solution for this?

AWS Lambda handles synchronous functions and asynchronous functions as well. async means two things:
The function returns a Promise
You are able to use await inside it
AWS Lambda happens to understand Promises as return value, thats why async functions work as well. So if you need await just go for async.
You could also not declare the function as async and return a Promise (or chain of Promises)
|
I'm creating an AWS SAM application using Node.js Lambda functions. The default template has an async handler function:
exports.lambdaHandler = async (event, context) => {
// ...
return {
statusCode: 200,
body: JSON.stringify({ hello: "world" })
};
};
Is there any benefit to having this handler function be async vs sync, since my understanding is each time a Lambda function is invoked it runs separately from other instances?

If you have to install your library to test it, you're doing something wrong. :) You are absolutely right that that is not a nice way to work. Here's a better way: Write tests—lots of tests—that you can run on your library to make sure it works. Since you're using PHP, use PHPUnit for this part.
If you do find a bug while using the library in one of your other projects, write a test that exercises that bug. Then you can code —> test —> repeat in your library until the tests pass again.

Let's say I have some pet-projects on Laravel (or any other PHP project with Composer).
They have some similar functionality and I want to extract in into a composer package hosted on GitHub.
What are my actions?
I see this approach:
Create a new project (e.g. in PhpStorm). Write an extension with tests (migrate from one of the projects).
Create a GitHub repository, push the code there.
Add it to packagist.
Composer require the package on all projects and install it properly.
This is ok. But what if I need to add some new feature or fix a bug? How do I do it properly?
It's convenient to try it directly on some of the projects, which has the extension installed, but it's strange to edit "vendor" directory, and even if the files are edited, how to push them back to the repository?
It's also awkward to edit the code in the separate PHPStorm project for the repository "blindly" and push it each time, the composer update from the project to see how it works.
Any other convenient flow? Thanks.

Fromthe docs:The database time zone [DBTIMEZONE] is relevant only for TIMESTAMP WITH LOCAL TIME ZONE columns. Oracle recommends that you set the database time zone to UTC (0:00)...SYSDATE/SYSTIMESTAMPwill return the time in the database server's OS timezone. Selecting aTIMESTAMP WITH LOCAL TIME ZONEdatatype will return the time in your session's timezone (ie,SESSIONTIMEZONE).select
CAST(systimestamp AS timestamp(0) with local time zone) as local_time,
systimestamp as server_time
from dual;DBTIMEZONEis only used as the base timezone stored inTIMESTAMP WITH LOCAL TIME ZONEcolumns - which you never see, because when you select from one of those columns it gets translated into your session timezone.See this similar question for a very detailed answer.

If you're running docker 1.9 or 1.10, and use the 2.0 format for yourdocker-compose.yml, you can directly access other services through either their "service" name, or "container" name. See my answer on this question, which has a basic example to illustrate this;https://stackoverflow.com/a/36245209/1811501Because the connection between services goes through the private container-container network, you don't need to use the randomly assigned ports, so if a service publishes/exposes port 80, you can simply connect through port 80ShareFolloweditedMay 23, 2017 at 12:19CommunityBot111 silver badgeansweredMar 28, 2016 at 20:23thaJeztahthaJeztah28.3k99 gold badges7474 silver badges9292 bronze badgesAdd a comment|

I am learning how to use Docker, and I am in a process of setting up a simple app with Frontend and Backend using Centos+PHP+MySQL.I have my machine:
"example"In machine "example" i have configured 2 docker containers:frontend:
build: ./frontend
volumes:
- ./frontend:/var/www/html
- ./infrastructure/logs/frontend/httpd:/var/logs/httpd
ports:
- "80"

- api

How is "least recently used" parameter determined? I hope that a dataframe, without any reference or evaluation strategy attached to it, qualifies as unused - am I correct?
Results are cached on spark executors. A single executor runs multiple tasks and could have multiple caches in its memory at a given point in time. A single executor caches are ranked based on when it is asked. Cache just asked in some computation will have rank 1 always, and others are pushed down. Eventually when available space is full, cache with last rank is dropped to make space for new cache.
Does a spark dataframe, having no reference and evaluation strategy attached to it, get selected for garbage collection as well? Or does a spark dataframe never get garbage collected?
Dataframe is an execution expression and unless an action is called, no computation is materialised. Moreover, everything will be cleared once the executor is done with computation for that task. Only when dataframe is cached (before calling action), results are kept aside in executor memory for further use. And these result caches are cleared based on LRU.
Based on the answer to the above two queries, is the above strategy correct?
Your example seems like transformation are done in sequence and reference for previous dataframe is not used further (no idea why you are using cache). If multiple executions are done by same executor, it is possible that some results are dropped and when asked they will be re-computed again.
N.B. - Nothing is executed unless a spark action is called. Transformations are chained and optimised by spark engine when an action is called.

I have the following strategy to change a dataframe df.
df = T1(df)
df.cache()
df = T2(df)
df.cache()
.
.
.
df = Tn(df)
df.cache()
Here T1, T2, ..., Tn are n transformations that return spark dataframes. Repeated caching is used because df has to pass through a lot of transformations and used mutiple times in between; without caching lazy evaluation of the transformations might make using df in between very slow. What I am worried about is that the n dataframes that are cached one by one will gradually consume the RAM. I read that spark automatically un-caches "least recently used" items. Based on this I have the following queries -

Crontab lets you execute 1 scheduled command/script at a time.
Piping the output of your script to Grep command won't work. Furthermore, crontab by default redirects output to dev/null, therefore you won't see the output unless you save it to a file.
I suggest something like this:
Edit your script to redirect it's output to a file with your grep command. For example by adding
DATE=$(date +"%m_%d_%Y")
some command | grep -v Warning >> /tmp/$DATE.log # Here
Edit your Cron job to execute the script every day like you did, removing everything after the pipe:
45 5 * * * /home/username/barc/backupsql.sh
In order to monitor the output you could use tail command as follows:
tail -f /tmp/$DATE.log

I have faced a similar problem and found a workaround insearch after APIwhich is not affected by that limit of 10k elements and thus can be useful in cases when you know you might have more than that and still want to render the total elements that are there. With the ability of relatively easy fetches without the hard restrictions on filters or search at the cost of a not-too-handy pagination, that can still be done somewhat easy.It is tricky to use, because:All indexes that you are searching in should be sorted by the unique field across all indexes"from" query parameter(of a page) should be set to 0send a "search after" value from last element on the the previous page of that fieldAnd you won't operate numbers in pages anymore, just the last elements of the pages, and the size of those pages that you want to see after that elementIt is not really an answer on how to jump to the last one but that is a solution to not changing the result window size, and or limiting resulting documents to 10k only

You can't edit built-in profiles. Instead, you'll have to create a new profile, and then you'll be able to edit the rules to your heart's content. I suggest you initialize your new profile either by copying the rules from the built-in profile of your choice, or by inheriting from that profile. Note that choosing the latter means your profile can (and probably will) be updated by upgrading your analyzers; each new version of SonarJava, for instance, implements new rules and many of them are added to the Sonar way profile.
|
I'm a big fan of SonarQube as a developer. This time though I need to do admin work since I need to configure it from a fresh install. I see this rule in SonarQube "Methods should not have too many lines" but I don't see that it belongs to any of the default profiles ("FindBugs+FB-Contrib", "Sonar Way"). I think that's the reason I don't see any rule violations of this type from any of the projects. I thought this should be part of a common default profile since this is a pretty common violation. How can I add this rule to the profile?
There are other rules that I need to add which I expected also to be in the default/available profiles already.

I am using the kubernetes ingress-nginx(on Google Cloud) controller for TLS.

The certificate I am using for the public key is the full certificate chain from Let's Encrypt. I'm not sure why nginx isn't attaching an OCSP response even though kubernetes supports OCSP.

When you clone a remote repository, by default your local working directory will be on the remote repository's default branch. For a long time this was the master branch, but GitHub has recently started using the name main instead of master.
It sounds like your repository may have been created someplace else and then pushed to GitHub. Regardless of how you arrived at this situation, you have two branches named main and master, and it sounds like main is the default branch.
After cloning the repository, you will be on the main branch. You can switch to the master branch by running:
git switch master
Or:
git checkout master
The main0 syntax is newer. The two commands are largely equivalent (main1 does more than main2).
You can change the default branch of your GitHub repository by going to your repository settings. Clicking on "Branches" along the left. This will take you to the branch settings, where the first section is the "Default branch" section.
Click on the icon with two arrows, then select main3 as your default branch.
In the future, main4 will result in a working directory that is on the main5 branch.

Beginner GitHub user here, cannot figure out how to use it.
I have a repository, it has two branches, one is called main, and it has a README file, and there is another called master, with all my other files. Only a few files.
I pushed them from my desktop, and when I want to clone or pull the entire repository to my laptop, it only pulls the README file, nothing else; so basically the content of the branch called main.
Any help will be greatly appreciated, thanks in advance.

The problem is that your rules don't match thessl non-wwwurls, so the redirection fromhttps://example.comtohttps://www.example.comisn't happening on your server. .You can use the following generic rule to redirect your domains tohttps://www:RewriteEngine on
RewriteCond %{HTTPS} off [OR]
RewriteCond %{HTTP_HOST} !^www\.
RewriteCond %{HTTP_HOST} ^(?:www\.)?(.+)$
RewriteRule ^.*$ https://www.%1%{REQUEST_URI} [NE,L,R=301]Make sure to clear your browser cache before testing these rules.

I agree that the UI in this case is not very self-explanatory. You should read the documentation (e.g.Target groups for your Application Load Balancers) first to get a general understanding of the relationship between a load balancer (LB) and a target group (TG). TL;DR, the TG is not associated to an LB directly. Instead, they are associated via a listener.A listener is a process that checks for connection requests, using the protocol and port that you configure. The rules that you define for a listener determine how the load balancer routes requests to its registered targets.Source:Listeners for your Application Load BalancersTherefore, the correct steps to take after clicking the "Associate with an existing load balancer" are:Select a load balancerGo to "Listeners" tabEither edit an existing listener or add a new listenerSet rules and conditions, and attach TG

I am trying to add a load balancer to a target group.In EC2 > Target Groups, I can see my target group that I want to add an existing load balancer to.So I select "Associate with an existing load balancer" which brings me to this page.I then select the load balancer... but then what? There's no button that says "Add load balancer to target group". The "Create Load balancer" blue button is there to create a new load balancer (not what I want). It doesn't look like anything in the "Actions" dropdown is appropriate. How can I attach the selected load balancer to the target group?

Am running Istio 1.12.1 version as well in my clusterOne of them is causing me some concerns:/apis/extensions/v1beta1/ingressesI was surprised to see this warning because we are up to date with our deployments.

I'm really new to the whole GitHub thing so this might seem like a basic question but I can't figure it out.
I have a GitHub repository set up on my machine, I've managed at some point to push the master but now I have made some changes and I want to push the entire thing again (pretty much everything changed).
What I'm wondering is:
How do you push an entire repository to create a new version (from version 1.0.0 to 1.0.1)?
How do you push a single file for more incremental changes?

How do you push changes to GitHub on OS X 10.6?

I'm not sure why you need all that data in the URL. You should be storing things like the submission title, its date and author in a database and then refer to it with an ID. That way, your URLs will be shorter and prettier:http://www.example.org/article.php?id=1http://www.example.org/article/1/You can accomplish this with a simple RewriteRule in your.htaccessfile, like so:RewriteEngine On
RewriteRule ^articles/([0-9]+)/ article.php?id=$1

I have two questions:Since I am using the GET method in PHP, the ugly URL has a bunch of variables appended to it. I don't want all of these variables to appear in the clean URL. Is it possible to only include a few of the variables in the clean URL but still have a rule directing it to an ugly URL with all of the variables?Once I have the .htaccess rules written, do I go back and change the links in the source code to direct to the clean URLs? If so, how do I do this using the GET method when the clean URL does not have all of the variables that I want to pass along?Thanks in advance,John

You can manually dispose your 2nd level cache for a specific entity, entity type or a collection.Fromhttp://knol.google.com/k/fabio-maulo/nhibernate-chapter-16-improving/1nr4enxv3dpeq/19#For the second-level cache, there are methods defined on ISessionFactory for evicting the cached state of an instance, entire class, collection instance or entire collection role.sessionFactory.Evict(typeof(Cat), catId); //evict a particular Cat
sessionFactory.Evict(typeof(Cat)); //evict all Cats

I've got a web application that is 99% read-only, with a separate service that updates the database at specific intervals (like every 10 minutes). How can this service tell the application to invalidate it's second-level cache? Is it actually important? (I don't actually care if I have too much stale data) If I don't invalidate the cache how much time is needed to the records to get updated (if using SysCache)

Yes, you are right. Pods on the same node are anyhow utilizing the same CPU and Memory resources and therefore are expected to go down in event of node failure.But, you need to consider it at pod level also. There can be situation where the pod itself gets failed but node is working fine. In such cases, multiple pods can help you serve better and make application highly available.
From performance perspective also, more number of pods can serve requests faster, thereby dropping down latency issues for your application.

I'm new with Kubernetes, i'm testing with Minikube locally. I need some advice with Kubernetes's horizontal scaling.In the following scenario :Cluster composed of only 1 nodeThere is only 1 pod on this nodeOnly one application running on this podIs there a benefit of deploying new podon this node onlyto scale my application ?If i understand correctly, pod are sharing the system's resources. So if i deploy 2 pods instead of 1 on the same node, there will be no performance increase.There will be no availability increase either, because if the node fails, the two pods will also shut.Am i right about my two previous statements ?Thanks

My current workaround is to simply create a 'bug reporting' account, and share that account's access token with the source code.
That remains the simplest solution, especially using a PAT (Personal Access Token).
As I explained in "Where to store the personal access token from GitHub", using a PAT allows for an easy revocation if needed, without having to invalidate the account password.

I have an electron app that has a bug reporting feature. I would like this bug reporter to use the github API to create an issue automatically. Here is the catch, I don't want my users to create and use their own github account to do so.
Is it possible to use the github API to create issues, without requiring an account?
My current workaround is to simply create a 'bug reporting' account, and share that account's access token with the source code. That way, whenever anybody creates an issue it's listed under that user. Seems like a stretch, and I'm wondering if there is a better way to approach this problem.

proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
}
}All good and when I rundocker-compose up, it gets two containers up and running which is also nice. From the host, when I hitlocalhost:5000, the request just hangs and when I terminate the request, nginx writes out a log through docker compose indicating499HTTP response.Any idea what I might be missing here?Update:I added some logging to ASP.NET 5 app and when I hit localhost:5000, I can verify that request is being send to ASP.NET 5 but it'sbeing terminated immediatelygiving a healthy response judging from the 200 response. Then, nginx sits on it util I terminate the request through the client.

The brief answer is you should never do such a thing as your API key will be exposed to the public.
The correct way of doing this is specifying environmental variables in your deployment environment, which you'll reference in your code. As every cloud Steamlit has an established approach for this, see their docs here. Hope this helps!

Stack-based storage is reclaimed as soon as the function call in which it resides returns.Is it possible that you were using heap-allocated memory (i.e. callingnew) within your recursive function? Alternatively, if you're simply looking at the Windows Task Manager or an equivalent, you may be seeing "peak" usage, or seeing some delay between memory being freed by your program and returned to the OS memory pool.Follow up (after question was edited):It's not clear what you are doing with thepair<Move*, Piece*>, so I can't tell if the Move objects need to be held by pointer or not. The primary reasons for holding them via pointer would be polymorphism (not used here since you don't appear to be creating subclass objects) and to allow their lifetime to be independent of the call stack. Sounds like you don't have that reason, either. So, why not:std::pair<Move, Piece*> pr(Move(x1,y1,x2,y2), aPiece);ShareFolloweditedMay 3, 2011 at 1:15answeredMay 2, 2011 at 20:50Drew HallDrew Hall28.7k1212 gold badges6464 silver badges8181 bronze badges1yea I found this new statement that might be the problem...(check updated description above)–user734027May 2, 2011 at 21:24Add a comment|

I was implementing a chess bot in c++ using recursive algorithms and the program evaluates over a million nodes per move.Over time the memory it takes up gets to over 1 GIG of RAM...But I don't really need the variables that were previously declared after I'm done with the move...So how do I manually flush the stack memory to get rid of the previously declared variables on the stack just like java's garbage collector?UPDATEI found out that there's this line in my source:Move * M = new Move(x1,y1,x2,y2);
pair <Move *, Piece *> pr (M,aPiece);and it's in the perform move function which gets called a million times in the recursion...My question is, how would you clear such variable once all the recursion is done and I no longer need this variable, but while the recursion is doing its thing, I need that variable to stay in the memory?

A change to the Template will only show up when that Template is used to stamp out new replicas. A change outside of the Template (replicas/selector) will be enacted immediately.

I have aReplicaSetdefined in a yaml file which was used to create 2 pods (replicas). It is my understanding that changes in thespecsection ofReplicaSetwill be interpreted as changes in the desired state that will eventually get applied to the real world. For example, PATCHing the number of replicas with:curl --request PATCH \
--header 'Content-Type: application/strategic-merge-patch+json' \
--data '{"spec":{"replicas":3}}' \
http://localhost:8080/apis/extensions/v1beta1/namespaces/default/replicasets/hello-v2causes the number of pods to change. However, if I patch the labels to add a label:curl --request PATCH \
--header 'Content-Type: application/strategic-merge-patch+json' \
--data '{"spec": {"template": {"metadata":{"labels":{"active":"true"}}}}}' \
http://localhost:8080/apis/extensions/v1beta1/namespaces/default/replicasets/hello-v2I don't see this change take place on existing pods. New pods (created, for example by scaling the ReplicaSetdocontain the new label.When does a change to aspecimpact the current state and when does it not?

Well, I don't think Sonarqube supports that.
The only thing that I see you could do, is to run the memory profiler as you are doing, but instead of uploading to sonarqube as per your approach, you could create a html report from the memory profiler results and attach it to your Jenkins build.
