You could rebase branch2 on top of master using --update-refs which is a newish option that will also update references that are setup in the path to branch2, so should move the position of branch1 .
git checkout branch2
git rebase --update-refs master
The kind of step by step way would be:
git checkout branch1
git branch temp # let's set a temporary marker before I move it
git rebase master
# now time to rebase branch2
git rebase --onto branch1 temp branch2
# remove the temporary branch if things went fine
git branch -D temp
The last rebase will rebase commits in the temp..branch2 range on top of branch1

My Scenario is this :
From master branch to feature branch1 , add changes to branch1 then create another branch from branch1 called branch2, then add changes to branch2.
If there are then pending changes to the master branch , what's the best approach to sync all branches with the master branch
Branch creation as follows Master to F1 then F1 to F2

Copy between S3 Buckets
AWS (just recently) released a command line interface for copying between buckets.
http://aws.amazon.com/cli/
$ aws s3 sync s3://mybucket-src s3://mybucket-target --exclude *.tmp
..
This will copy from one target bucket to another bucket.
See the documentation here : S3 CLI Documentation
|
I have been on the lookout for a tool to help me copy content of an AWS S3 bucket into a second AWS S3 bucket without downloading the content first to the local file system.
I have tried to use the AWS S3 console copy option but that resulted in some nested files being missing.
I have tried to use Transmit app (by Panic). The duplicate command downloads the files first to the local system then uploads them back to the second bucket, which quite inefficient.

You can't.
You may try to allocate a memory on the heap at the beginning of you program, and compare the address to the pointer you want to free, but it will not be accurate in many of the cases. And what you might find and use on one platform after some research of its memory management, might not be relevant on the next.
An alternate way is to add a memory management module to your program, which will wrap the malloc, free etc. functions and will keep track of all allocated memory and will call free only if the pointer appears in his list. While this might seem like a lot of work to avoid memory leaks, I've found it very convenient many times.
EDIT
As mentioned in comments, the best way to decide is simple - free it in a place where you know if it's was located on the heap or not. I cannot tell you how easy it is in your case, but usually it shouldn't be too hard, many programs / programers did it before, and I doubt someone actually tried to check where the memory was allocated at.
|
A block of memory can be allocated statically, in the stack or in the heap. I want to know a way to detect if a pointer points to the heap. I work with Windows and Linux and it is not a problem a different solution for each OS. I use GCC and Mingw.
If I could know where the heap begins and where it ends, I think the problem can be solved. I think that I can detect the bottom and the top of the stack in order to know if the block is in the stack, but if there are multiple threads, then there are multiple stacks. Even I could to know where is the static memory, I think I will have problems with static memory blocks of shared libraries.
I think I will have a problem if the pointer does not point to the beginning of the block:
type* x = &(pointer[3]);

The short answer is no as of this writing. AWS Codebuild does not support the webhook for when a tag is created.My original question was targeted towards creating an easy build system with semantic version attached. I got around the tag issue by creating a branch filter and a bash script.1) I made my branch filter bebuild-[0-9]+.[0-9]+.[0-9]+.2) The I wrote a bash script that:increments the semantic version, triggering a change in the repo.commits the change to my whatever my deploy branch is. (master)creates a new branch with a name that matches the regex above, that also contains the version within it. e.g, build-0.2.11, build-1.2.3, etc.deletes the newly created branchJust the creation of the remote branch will trigger github to fire the push webhook over to AWS.

The idea behind the link between GitHub issue and Mylyn is to define aquery:GitHub issue task repositories support creating queries that filter by the following fields:State (open or closed)MilestonesMentionsAssigneeLabelsSo if you don't define a query for the issues (especially for the ones assigned toyouor your team), you won't see them.That query will use theGitHub v3 API for issues.(Huboardis an example of another service, beside Egit, which uses that API: as described inHuboard – Github issues made awesome, byRyan Rauh) | I'm using this GitHub Mylyn connector:http://marketplace.eclipse.org/content/github-mylyn-connectorHowever, when someone is creating an issue on GitHub itself, it doesn't get updated in my tasks in Eclipse.
I am working in a team, therefore want to have the possibility to share all the tasks. The idea behind Mylyn was to create tasks, sync it with GitHub and everyone else will just sync their task list against the issue list on GitHub.
As I mentioned, somehow it doesn't sync any tasks that were created on GitHub itself, therefore I assume that tasks I create in Mylyn and sync with GitHub won't be synced to my colleagues computer as well.Any solution for this? | GitHub Mylyn connector: Getting issues from GitHub |

Yes, that's true, it'sreadinessprobedesigned to.When readiness probe is not passed, the pod will be inNotReadystatus, thus doesn't appear in the Endpoint list, while only the Pods in the Endpoint list will be resolved by coredns.

Without seeing your code it is difficult to find exact issues. But I you should start from finding code where new objects are instantiated/destroyed. It causes GC to collect unused objects and allocate new memory. And soon your free memory becomes so fragmented that there is no suitable memory area to allocate new object.

So I already asked this question on the unity forums but that didn't help me a lot :/. Today I decided to give my game a try with friends so basically I created a server so other clients/friends could connect to it. After about 20 minutes of playing my game crashed and I quickly checked task manager and my game was using about 3.5 GB of RAM! PHOTO HERE When I looked at the log it said something like this:
Unity Player [version: Unity 4.6.1f1_d1db7a1b5196]
mono.dll caused an Access Violation (0xc0000005)
in module mono.dll at 0023:101071a1.
Error occurred at 2016-07-04_163050.
C:\Users\Cooler Master\Desktop\TL\TL.exe, run by Cooler Master.

0 MB physical memory [1814 MB free].
0 MB paging file [1039 MB free].
0 MB user address space [68 MB free].
Write to location 00000000 caused an access violation.
So in my game there is something that keeps eating my RAM. It takes about 3MB per second of ram when the game is running. I found some information on internet about Resources.UnloadUnusedAssets but I don't know how to write a script like that! I knew how to write in c# but only the easy scripts like GUI,Newtorkinf,Physics etc.. Also I downloaded unity pro from kickasstorrent only to see profiler window but that didn't help me at all
Thank very much for any reply !

Retrofit itself does absolutely no caching.If you want caching, it will either have to be at the application layer above Retrofit which knows about your domain and how to cache things in it or it needs to be at the HTTP client layer below Retrofit which knows the semantics of HTTP.OkHttpis an HTTP client also by Square which supports the semantics of caching server responses.

| How to create AMI from EBS snapshot with AWS CLI |
There are several problems with your unsuccessful approach:
proxy_set_header sets the header that goes to the upstream server, not to the client. So even if $sent_http_location hadn't been empty, your configuration couldn't possibly work as you wanted it to.
$sent_http_<header> variables point exactly to the same area of memory as the response headers that will be send to the client. So when proxy_hide_header takes effect, the specified header is being removed from the memory along with the value of the corresponding $sent_http_<header>.
set_escape_uri works at a very early stage of the request processing, way before proxy_pass is called and the Location header is returned from the upstream server. So it will always process the at that time empty variable $sent_http_location and the result also will always be the empty variable.
The last problem is the most serious. The only way to make set_escape_uri work after $sent_http_location0 is to force Nginx to leave the current location and start the processing all over again. This can be done with the $sent_http_location1 trick:
$sent_http_location2
Note the use of $sent_http_location3 instead of $sent_http_location4. When Nginx leaves the context of the location, it assumes that the request will be proxied to another upstream, or processed in some other way, and so it clears the headers recieved from the last $sent_http_location5, to make room for new response headers.
Unlike $sent_http_location6 vairables, which represent response headers that will be send to the client, $sent_http_location7 variables represent response headers that were recieved from the upstream. Because of that, they are only replaced with new values when the request is proxied to another upstream server. So, once set, these variables can be used at any moment, they will not be cleared.

I have a web application that wants to access files from a third party site without CORS enabled. The requests can be to an arbitrary domain with arbitrary parameters. I'm sending a request to my domain containing the target encoded as a GET parameter, i.e.
GET https://www.example.com/proxy/?url=http%3A%2F%2Fnginx.org%2Fen%2Fdocs%2Fhttp%2Fngx_http_proxy_module.html
Then in Nginx I do
location /proxy/ {
resolver 8.8.8.8;
set_unescape_uri $dst $arg_url;
proxy_pass $dst;
}
This works for single files, but the target server sometimes returns a Location header, which I want to intercept and modify for the client to retry.
Basically I would like to escape $sent_http_location, append it to https://www.example.com/proxy/?url= and pass that back to the browser to retry.
I've tried doing
set_escape_uri $tmp $sent_http_location;
proxy_redirect $sent_http_header /pass/?v=$tmp;
but this doesn't work. I've also tried saving the Location header, then ignoring the incoming header with
proxy_hide_header
and replacing it with my own
proxy_set_header
but ignoring causes me to lose the variable saving it.
How can I configure Nginx to accomplish this handling of redirects so that I could pass a encoded URL would be returned to the user when the proxied site redirects?
| Nginx proxy intercept redirect and pass custom redirect to client |
It can works but it requires that the containers are aware of the environment variables. So you may need to declare the variable in theDockerfileand you must use the environment variable in theCMDinstruction that is used to start the process in the container.

These images can be cached for a reasonable amount of time, as stated in the terms, so we don't have to hit up the other website's servers on every page request.I am new to caching, but I just watched some Railscasts about some different methods.page caching,fragment caching,dynamic page caching. They all help decrease the requests and therefor the speed ofmyapp.But how would I go by 'caching' images from another site on my servers? What is the correct way to do so? Are there any functions to serve this purpose?My attemptwould be to add a timestamp,cache_outdates_atto myImagemodel and set it one month into the future. Whenever the image get's loaded again it would update the timestamp.Then I'd add a cronjob to check for outdated images and then delete them. | server side image caching |
I believe it is a combination of both... You can tell that "X-Powered-By: PHP/5.3.6-6~dotdeb.1" comes from PHP and "Server: nginx" comes from NGINX.You can alter the headers in PHP as follows:The gzip header most definitely comes from NGINX as it is compressing the output (html) to the browser. PHP can "add" to the headers by calling a function like the one above. Then the server combines it with the PHP headers and serves the request.It depends on your server whether or not the PHP headers take precedence over the server headers.Hope this helps. | When I simply echo something out of php file, I do not send any headers intentionally, however - there are some default headers present anyway when I look at firebug response:response headers:HTTP/1.1 200 OKServer: nginxDate: Thu, 23 Jun 2011 19:33:51 GMTContent-Type: text/htmlTransfer-Encoding: chunkedConnection: keep-aliveVary: Accept-EncodingX-Powered-By: PHP/5.3.6-6~dotdeb.1Expires: Thu, 19 Nov 1981 08:52:00 GMTCache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0Pragma: no-cacheContent-Encoding: gzipI'm curious - are these default response headers set by the server(nginx) or by PHP? | Where are these extra HTTP headers coming from? |

What you need to do is supervise your file using inotify, and whenever this file changes, call the Docker API so that it resets the container.
In order to call the Docker API from inside a container, you mount the Docker socket inside the container like this:
docker container run -it -v /var/run/docker.sock:/var/run/docker.sock ubuntu
You then install the required utilities inside the container:
apt-get update; apt-get install -y curl inotify-tools
You then write the script that should be called whenever your target file changes:
echo "curl --unix-socket /var/run/docker.sock -X POST http:/v1.24/containers/<container_to_reset>/restart" > script
chmod +x ./script # Make sure the script is executable
Finally, you run a loop that executes your script whenever the target file is modified:
while inotifywait -e close_write <target_file>; do ./script; done

I have a spring-boot application running on java images in container. In Dockerfile I am copying jar file. Then build custom image for my project & run it
I am thinking what if I will volume-map my jar file. At least it will run for the first time.
I want some functionality like when I change volume map file in my host computer the docker need to be rerun.
For HTML, nginx will work fine as it is just rendering html files in the particular folder without rerun. But, I doubt if it will work for java
For rerun automatically what is the commands. Will it happens automatically?

You misunderstand howinternalandX-Accel-Redirectwork.The main idea is that you go to some URL which is proxied to app. Then app decides whether you should get access to file or not. In former case it response withX-Accel-Redirectto protected url (one withinternal).So you should go to some other URL, e.g.http://localhost:4000/get/files/test.jpgand your application could look like this:var http = require('http');
http.createServer(function (req, res) {
if (req.url.indexOf('/get/files/') == 0) {
if (userHasRightToAccess()) {

I had the same issue. BitLocker cant be disabled as it is a company policy. I Resolved it by doing the following:
Step 1: Open Command Prompt and Type: regedit
Step 2: Navigate to "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Policies\Microsoft\FVE
FDVDenyWriteAccess".
Change "FDVDenyWriteAccess" to "0".
Step 3: Restart Docker and it should work as expected.
Note: You should be an Admin on your local box to execute the above steps.
Officially it is still a unresolved issue Till Date: https://github.com/docker/for-win/issues/1297.

I solved it, and I'm not sure why, but I got it working using port 80 inside the Docker container. The port on my localhost is still 4200, but inside the container, it's 80, so I ran the container like this:
docker run -p 4200:80 -d mydhid/project
I think I have changed something in the dockerfile too, here's the one I'm using right now if it can be helpful:
FROM node:latest as node
WORKDIR /app
COPY . .
RUN npm install
RUN npm run build --prod
FROM nginx:alpine
COPY --from=node /app/dist/front-end-blog-demo /usr/share/nginx/html
I tried again running it as 4200:4200, and it's not working. It seems that the Docker port must be mandatory at 80.

FROM node:16-alpine AS build
WORKDIR /app
COPY package*.json ./
RUN npm install
COPY . .
RUN npm run build

I build it with: docker build -t mydhid/project .
pushed it, and ran it with: docker run -p 4200:4200 -d mydhid/project

If you need something similar to JavaScript allocations timeline, you can do the exact thing in Safari following these steps
Safari DevTools -> Memory tab -> Start Recording JavaScript Allocations
Let the application run for a while; then stop the recording and check the timeline for any significant allocations
In addition, you can do a couple other checks as described below
Safari DevTools -> Memory tab -> Start Recording Heap Allocations
After a while, stop the recording and check the timeline for any significant allocations
Safari DevTools -> Memory tab -> Record
Again, stop the recording after a while, take a snapshot using the Take Heap Snapshot button and then compare multiple snapshots in order to identify objects that aren't being garbage collected.

I'm having trouble understanding these instructions. Safari's dev tools don't have a Memory tab. This question was about what Safari reports as its "Page" memory usage, which it lists separately from "JavaScript" memory.

@JoshKelley I must have a custom version of Safari, just kidding... ;) Safari -> Preferences -> Advanced tab, check the box next to 'Show Develop menu in menu bar'. Then 'right click' on your page -> Inspect Element -> Tmeline -> Memory

I am trying to debug a large memory leak I am seeing in a webview embedded in a unity app. Unfortunately, I am stuck using safari dev tools.
In the dev tools I see that my JS heap is staying steady, around 75mb. However, my "page" memory is growing quickly. Over the course of 10 minutes or so it grew from 272mb to up over 1gb.
I don't know how to tell what is taking up all that "page" memory. Is there a way I can see what is building up, similar to the javascript allocations timeline?
| How do I debug a buildup in "page" memory in safari dev tools? |
Memory is "stomped" when a piece of code manipulates memory without realizing that another piece of code is using that memory in a way that conflicts. There are several common ways memory can be stomped.One is allocating, say, 100 bytes of memory but then storing something past the 100th address. This memory might be used to hold something completely different. This is particularly hard to debug because the problem will appear when something tries to access the victim that was stomped on, and the code that stomped on it may be totally unrelated.Another is accessing memory after it was freed. The memory may be allocated for another object. Again, the code that shows the problem may be related to the newly-allocated object that got the same address and unrelated to the code that caused the problem. | I just cameacross this blog postwhich mentions “stomping memory”:a C++ program which is easily capable of stomping memory

Thememory_get_usagefunction directly queries PHP's memory allocator to get this information. It reports how much memory is used by PHP itself, not how much the whole process or even the system as a whole is using.If you do not pass in an additionaltrueargument what you get back is the exact amount of memory that your code uses; this will never be more than whatmemory_get_usage(true)reports.If you do callmemory_get_usage(true)you will get back the size of the heap the allocator has reserved from the system, which includes memory that has not been actually used by your code but is directly available to your code.When your script needs more memory than what is already available to the allocator, the latter will reserve another big chunk from the OS and you will seememory_get_usage(true)jump up sharply whilememory_get_usage()might only increase by a few bytes.The exact strategy the allocator uses to decide when and how much memory to allocate is baked into PHP at compilation time; you would have to edit the source and compile PHP to change this behavior. | I decided to take a look at how much memory was being allocated to a few of my PHP scripts, and found it to be peaking at about 130KiB.

After that, I tried testing a completely devoid script:<?php
echo memory_get_usage();It also started with the same amount of memory allocated.Now, obviously, PHP is going to allocate some memory to the script before it is run, but this seems a bit excessive.However, it doesn't seem to be dynamic at all based on how much memory is available to the system at the time.

My integration tests have dependency on redis. They have dockerfile included, so everything works in CI. However when running locally from test explorer I have to manually start redis container.
Is there possibility for IDE to automatically run/debug tests in docker containers, so when attemptying to run/debug test in IDE (or maybe even using dotnet test) everything runs in docker?

The way I've been able to successfully work with GitHub in a team is to make everything a prefab. To clarify, I looked at my hierarchy top level, and tried to make everything there a separate prefab. e.g.
root
.Camera Items
.Game Manager Items
.Level Game Objects
By separating areas of concern into separate prefabs, you can modify the prefab, which is saved as an asset, and the actual Scene itself isn't modified.
To break it down, if your scene is made up of the three items listed above, then it doesn't matter how much you modify your specific prefabs, the scene is STILL just made up of the three prefabs. The scene doesn't store the prefab details, just a reference to the prefab.
So, Person A can be working on the Game Manager prefab, and Person B can be working on the Level Game Objects prefab, and when it comes time to commit, the scene itself hasn't changed.
The one point is that the prefab overrides ARE saved in the scene, so, to make things easier, we simply made sure our prefabs were completely saved before committing.
It's not easy to get into the swing of it, but when you do, it's workable. Not great, but workable.

You need to create appropriate IAM policy (such as AWSLambdaKinesisExecutionRole tailored to specific stream that you want to share).
Create IAM role of type Another AWS Account where you need to specify account ID of the account with which you want to share your stream, and attach the above mentioned IAM policy to that role.

There is nothing immediately planned (3-4 years) around ADO retirement. This is emphasize by the recognition there are more mature tools in Azure DevOps around Project Management and event some features which have no immediate counterparts in GitHub. Azure Test Plans is the prime example if you are using manual test cases there is no planned alternative on GitHub's roadmap.
The focus has been on integration between GitHub and Azure DevOps. There have been recent announcements that support this. Items such as Advance Security for GitHub coming to ADO and the ability to connect GitHub to Azure DevOps Orgs. ADO Public roadmap
I am seeing more and more where organizations host their source code in GitHub to take advantage of newer features such as codespaces and the recent announcement of Co-Pilot X.
Then Azure DevOps can read the GitHub repository and then the organization can decide if they want to use ADO Pipelines or GitHub Actions. Both are supported. The tasks, project management, and test cases would still live in Azure DevOps.
The reoccurring message I am hearing is if you are a startup or brand new should evaluate GitHub first; however, Azure DevOps is a valid option as most major organizations, including Microsoft, are still heavily invested in the product. Thus there is a focus on integration between the two products and it's more of an AND then a VS conversation.

Is it better to host code on Github or in the DevOps code platform?

A question came up about a new repo and I am wondering pros and cons of putting it in one vs the other?

The standard doesn't say (it doesn't know about "stack", "heap" etc). But in practice the answer is: Neither. The string literal will be stored in the data section, usually in a read-only page.

Your comment seems to say the opposite of the codeproject site. The site says you are able to debug both projects using the single docker-compose startup project, not multiple startup projects. I haven't tested this to know what's the case.

I've got a solution that contains two dockerized web projects. I've got my docker-compose file setup to deploy both of those projects.
Both of those projects are set (in their respective projects), to launch a browser when they are debugged.
When I hit F5 to debug, it consistently starts a web browser pointing at one of those two projects, but not the other. Nor is the one that it's picking the one we'd generally prefer to have launched. Is there a way to control how many and which projects launch browser windows when debugging a docker solution containing multiple containers?

Do not use an unbounded queue. I cannot tell you what the bound should be; your load tests should give you an answer to that question. Anyhow, make the bound configurable: at least dynamycalliy configurable, better yet adaptable to some load measurement.
You did not tell us how the clients submit their requests, but if HTTP is involved, there already is a status code for the overloaded case: 503 Service Unavailable.

Brief
I am running a multithreaded tcp server that uses a fixed thread pool with an unbounded Runnable queue. The clients dispatch the runnables to the pool.
In my stress test scenario, 600 clients attempt to login to the server and immediately broadcast messages to every other client simultaneously and repeatedly to no end and without sleeping (Right now the clients just discard the incoming messages). Using a quad-core with 1GB reserved for heap memory - and a parallel GC for both the young and old generations - the server crashes with a OOM exception after 20 minutes. Monitoring the garbage collector reveals that the tenured generation is slowly increasing, and a full GC only frees up a small fraction of memory. A snapshot of a full heap shows that the old generation is almost completely occupied by Runnables (and their outgoing references).
It seems the worker threads are not able to finish executing the Runnables faster than the clients are able to queue them for execution (For each incoming "event" to the server, the server will create 599 runnables as there are 600 - 1 clients - assuming they are all logged in at the time).
Question
Can someone please help me conceive a strategy on how to handle the overwhelmed thread pool workers?
Also
If I bound the queue, what policy should I implement to handle rejected execution?
If I increase the size of the heap, wouldn't that only prolong the OOM exception?
A calculation can be made to measure the amount of work done in the aggregation of Runnables. Perhaps this measurement be used as a basis for a locking mechanism to coordinate clients' dispatching work?
What reaction should the client experience when the server is overwhelmed with work?

The basic idea is that we follow these steps:
Create a new empty repository App or whatever
Make an initial commit because we need one before we do a merge.
Add a remote to old repository OldA.
Merge OldA/master to New/master.
Make a subdirectory OldA
Move all files into subdirectory OldA.
Commit all of the file moves.
Repeat 3-6 for OldB.

The GPU is a separate core you can only interact with via MMIO; it's not a coprocessor like x87 originally was (wherefmulran on a separate chip). You can access it the same way the graphics drivers do.There is no CPU instruction that does stuff on the GPU directly because it's not tightly-coupledat all, hence the high latency being a problem for GPGPU. Sending work to the GPU looks like storing to memory and then passing a pointer to that physical memory to the GPU, e.g. viamov [mem], raxor something to the address of one of the GPU's MMIO registers.For Intel, those are open source if you really want to dive in to Linux DRM (direct rendering manager) and X11 drivers that talk to the GPU after asking the kernel for access. | My oldish PC has an Intel HD 420 in it.I was wondering - we can use Assembly code to address the CPU directly, with commands likemul,addetc.How can I pass on Assembly calculation commands to a graphics chip such as the Intel HD, or say the "gpu part" of AMD's Ryzen? Is it the same mechanics as for an ARM graphics chip?(No tags for apu, onboard-graphics, intel-hd, ryzen)Edit: I understand that OpenCL is the correct approach, and that an on-board chip is as good as any other peripheral hardware (eg printer) as far as communication.

You are duplicating server configuration. Simply keep one server properties set :
server {
listen 80;
root /var/www/html/Web/dist;
location /api/ {
proxy_pass http://localhost:3000;
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;
}
}
That means :
listens to all request for all ip's on port 80
Evaluate relative path from root /var/www/html/Web/dist;
if there's a matching '/api/' in url pass it to localhost:3000
It should work as expected now

I have been searching for this answer for months and have never been able to resolve this. I am using nginx as my web server and using node.js for my backend apis and vue as my main front end webpage that uses webpack. I would like to be able to go to my Vue page by going to http://ip and then get access to the api services by going to http://ip/api. I dont have a domain name set up so I use IP address for the urls.
So far I built my Vue app and is sitting in the /var/www/html/Web/dist folder and it works if you go to the http://ip url but I can not access my node.js APIs. My node.js server is running on localhost port 3000. My nginx config looks like this:
server {
listen 80;
root /var/www/html/Web/dist;
}
server {
listen 80;
location /api/ {
proxy_pass http://localhost:3000;
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;
}

Your observation is absolutely true, If you are using Fargate Launch type, its mandatory to give Task Size because for Fargate pricing calculation is based on Task Size and in case if application tries to consume more resource(CPU or Memory) than specified its size, they are killed and you'll exit code as 137, which seems logical.
This situation can be addressed in two ways:
Benchmark application against load and set appropriate Task Size.
If load is unpredictable, use service autoscaling based on service CPU Utilization and Application Load Balancer in front of Fargate service, this will scale out your service under load conditions and will scale in when there is no CPU utilization.
I hope this will help in stabilizing your micro application.

I have setup a ecs task with one container using fargate. The task and container have cpu and memory limits set. I can see that my container will shutdown occasionally for some unknown reason. At the time of shutdown and restart the max cpu is 100% and the minimum 0%.
I am trying to workout if the container shuts down due to my application hitting some limit internally or AWS shutting it down when the CPU hits 100%. I know memory is a hard limit which triggers a shutdown but I don't know if CPU is the same way?
thanks in advance!

Disclaimer: This answer is not based on any documentation but only on my interpretation of these constants.
I assume that the page size is correctly reported. I assume the allocation granularity refers to the granularity of the OS memory allocation interface.
There are these two cases to consider:
the allocation granularity is greater than the page size. Allocating a memory block of the size of a page would then lead to an actually larger allocation of resources, thus it should be prevented.
the allocation granularity is less than the page size. Allocating a memory block of the size of the allocation granularity would still lead to a whole page being allocated/mapped, thus it should be prevented.
Basically both cases would cause the OS to allocate more memory than requested. By using the maximum this can be avoided, such that the (user space) allocation code can be (relatively) certain about its actual memory usage.

Your reasoning is pretty correct. Documentation (msdn.microsoft.com/en-us/library/windows/desktop/…) for the SYSTEM_INFO data structure tells that dwPageSize is the page size and the granularity of page protection and commitment. This is the page size used by the VirtualAlloc function. Then dwAllocationGranularity is the granularity for the starting address at which virtual memory can be allocated. My doubt is if this two values are kind of rigidly system defined or more flexible and customizable.

I’m reading the Google’s TCMalloc source code (the Windows porting).
int getpagesize()
{
static int pagesize = 0;
if (pagesize == 0)
{
SYSTEM_INFO system_info;
GetSystemInfo(&system_info);
pagesize = std::max(system_info.dwPageSize, system_info.dwAllocationGranularity);
}
return pagesize;
}
As you can se in the code snippet above pagesize(that is the unit of allocation) is calculated as the max between dwPageSize and dwAllocationGranularity.
What I mean to know is the kind of relationship between these two values: is it necessary to calculate the value in the way here upside explicated? And are there any situations in which dwPageSize could be greater than dwAllocationGranularity?

You're almost there. The link that you've provided address your issue directly:If your function also requires internet access (for example, to reach a public AWS service endpoint), your function must use a NAT gateway or instanceYou're missing this:Your VPC should contain a NAT gateway or instance in a public subnet.This means that without a NAT, your Lambdas won't be able to access the internet - even though "they are" in a public subnet. This is how lambda fundamentally works in VPCs.The exact samelinkthat you provided instructs you on how to create this NAT Gateway alongside your VPCs and Lambdas.Complementing the answer - onwhy you would need a NAT Gatewayin this scenario - is due to:... you can use a network address translation (NAT) gateway to enable instances in aprivate subnetto connect to the internet or other AWS services, but prevent the internet from initiating a connection with those instances...Extracted fromaws docsKeep in mind:If you need your lambdas to accessonly the internet- and not any other resource in the same VPC - I recommend to make them non-VPC and then they'll have internet access out of the box - and you won't pay for the cost of NATs. | I have a lambda function that simply does anhttp.gettohttp://www.google.com.

Since GitHub is using linguist to detect languages, you can open a PR to report some files incorrectly tagged as "Smalltalk".
For instance, issue 2012 is still active (even though it is closed).

I have a personal repository on GitHub that is completely written in C#, with a few XML configuration files, and some PowerShell files from included NuGet packages. On the main repository page, GitHub shows a colored bar to display the breakdown of different languages used in the repository.
If you click this bar, it shows the language names and actual percents.
This particular language breakdown seems a bit odd to me, since I am the only contributor, and I have never used Smalltalk.
If you click a language name, it will show you a list of the files using that language.
In this last image, you can see on the left side that the repository really only contains C#, XML, PowerShell, text and markdown files.
So why does GitHub think I'm using Smalltalk? And why doesn't the color bar mention that I'm using XML?

I have a simple docker file, as follows:

Normally to install drivers for Mongo or MySQL connectivity I would do so by adding something like the below to the dockerfile:
docker-php-ext-install mongo

I've tried doing a pecl install, like adding:
RUN pecl install sqlsrv pdo_sqlsrv
However this fails with a combination of errors that do not seem to point me in the right direction.
I'm just looking for a simple way to get this done in a dockerfile or by using docker run.

Theproxy_next_upstreamdirective is a configuration directive to control re-request from a group ofupstream serversby aproxy_passif request to one of them fails. It doesn't make sense withoutproxy_passand anupstreamblock defined. You may use it if you proxy to multiple upstream servers like this:upstream backends {
server 192.2.0.1;
server 192.2.0.2;
...
}
server {
...
location / {
proxy_pass http://backends;

}
}If you want nginx to search for a file on disk, and if it's not found - proxy request to another server, configure it e.g. usingtry_filesfallback instead:location / {
root /path/to/root;
try_files $uri @fallback;
}
location @fallback {
proxy_pass http://...

Just reset your branch to the upstream version:
git reset --merge origin/dev
This will discard all 5 of your changes.
Then push the result to your fork:
git push -f fork
Note that you must use -f, otherwise your push will fail, because normally the server does not allow to discard commits.

I have made a change to my fork that was a mistake so now i want to reset my fork to that of the origin. Note change was already pushed to GitHub.
C:\Development\IdentiyServer\IdentityServer4>git remote -v
fork https://github.com/XXXXX/IdentityServer4.git (fetch)
fork https://github.com/XXXXX/IdentityServer4.git (push)
origin https://github.com/IdentityServer/IdentityServer4.git (fetch)
origin https://github.com/IdentityServer/IdentityServer4.git (push)
As you can see I have two remotes set up origin is the main repo and fork is the fork on my GitHub account which i have access to push to. I have to do pull requests from my fork to send them over to the main repo.
I did a pull on the main project to be sure it was to date
C:\Development\IdentiyServer\IdentityServer4>git pull origin dev
From https://github.com/IdentityServer/IdentityServer4
* branch dev -> FETCH_HEAD
Already up to date.
I did the same on my fork
C:\Development\IdentiyServer\IdentityServer4>git pull fork dev
From https://github.com/XXXXX/IdentityServer4
* branch dev -> FETCH_HEAD
Already up to date.
I did a checkout on the dev branch
C:\Development\IdentiyServer\IdentityServer4>git checkout dev
Already on 'dev'
Your branch is ahead of 'origin/dev' by 5 commits.
(use "git push" to publish your local commits)
Which clearly shows that there are changes in my fork/dev that are not in origin/dev good these are the ones I want to remove. I need to dump this change and get my fork back to the state of the origin.
reading this syncing-a-fork So i figured i should just merge in the origin/dev branch
C:\Development\IdentiyServer\IdentityServer4>git merge origin/dev
Already up to date.
I check the file and i can see that it hasn't been reset yet, and git checkout dev is still saying that its ahead of the origin. I am thinking that somehow i need to roll back the last change but I am not sure how to do that.
