Right now, i am working on a go ahead embedded web server. i have an old 2.1 version of this server, which was open source. i want to upload .json file which i create from the firmware, to the web server and then want the page to process that file using flot tool,and display a graph.but that version does not support file uploading capability. on internet i have found that the new version of this web server support the file upload capabilities, but i have not found a proper example which explains the syntax that i would use to upload the file. can any one tell me which functions of this new version i would have to use to get things working.
can any one give a proper full example.
You ask how to upload using goahead.
When you build the source, it should build a test executable called goahead-test. This uses test/test.c as a main program. Test.c defines an upload action handler that is invoked when you do a file upload to the url /action/uploadTest. This handler will echo back to the browser the various file upload details. You can cut/paste from test.c into your own main program.

Testers may have this issue for sure.
Assume that we have a testcase that should be automated. And it has a step to download a file from the webpage by clicking a link and it will be downloaded to our local machine’s download folder. As the next step it should be verified that the file is downloaded.
So in a local machine this can be handled easily by using the download paths and all. But the matter that I have is this exact same testcase is getting fail in Jenkins (cloud run). It returns a null value because the download directory cannot be found in Jenkins.
Do you guys know what kind of solution that can we take for this? I heard something using API request to download the file. Yes this file is also getting downloaded by a GET request with parameters. But I don’t know how to perform that.
Thanks for your time.
I tried the bellow options.
Changing the directory to Windows and Linux as per the documents
By using jenkins home directory
What I want to do?
to verify that the file is downloaded
Read the file and check with the db (This has existing methods)
I have used Spyder (Anaconda) to generate a Python GUI App. The app can browse & load any time series csv file on the user's pc, perform few statistical tests and print the results on to a txt file and save it to the user's desktop screen.
Is it possible to upload the executable file on to any repository so that others could try it out. For example, Google Earth Engine based apps can be easily shared via a link and anyone with that link can access the app. Similarly, is there anything for my case ?
This may not be the answer your looking for,
But you can upload .exe to Google drive and share it. So anyone could download it from the link generated.
File types: Users can upload any type of file, including executables
(for example, .exe or .vbs) and compressed files.

I was trying to upload and download files at application level using jelastic server in cloud and I have some issues during downloading the uploaded files
to upload the files I use:
File folder = new File(".." + File.separator + "customFolder");
and the files are uploaded correctly inside of:
/opt/GlassFish/glassfish/domains/customDomain/customFolder/
and I can see the files using jelastic dashboard and ssh
but, if I try to download them through application I have a 404 error
using this kind of approach

I try to use the instructions posted here
Cann't get file from classpath (using NIO2)
but this doesn't work for me. Also I try to use some paths also posted in jelastic documentation (https://jelastic.zendesk.com/hc/en-us/community/posts/206122066-Uploading-Files-to-a-Specific-Folder) but noticed there is no a clear explanation for Glassfish.
Also I figure out that the files are in different locations inside of jelastic application folders
these are the different locations that I have found and tried to use to downloading the files (I changed the access permissions, also without making a successful download):
/opt/GlassFish/glassfish/domains/customDomain/customFolder/
/opt/repo/versions/4.1.1/glassfish/domains/customDomain/customFolder/
/opt/shared/glassfish/domains/customDomain/customFolder/
so my question is
what is the correct path to download the files or should I change the upload path?
an example using java code returning the string with the path for download would be appreciated
I'm using Glassfish 4.1.1 for the application
I'm trying to create an updater for my app in VB.NET, No, I do not want to use clickonce, it sucks because I have to deal with managing self signed certs etc.
I know the code to check for new update files:
http://pastebin.com/ZjYBWABu
I also know the code for specifying where those files download to, the issue is I dont want to just download 1 .exe...I want to download all the latest build files which I would have uploaded to my server, which i would have taken from my Bin\release folder of my project.
Then when the updater downloads the files to a directory, it would go to the directory of the application, and somehow overwrite/replace all the files that have changed...maybe by using a hash or something?
I do not know how to proceed with this. What I do know is this.
The updater and the main app would have to be separate so that the updater could do the replacing while the app is closed so it doesn't get file in use errors. After the updater app has finished it would then start up the main app from the new exe.
Would appreciate help here thank you guys.
I am currently working on a project for which I have to implement a similar approach for updates. The project is lengthy, it would take some time to finish. But this is how I have planned to apply the updates:
There will be two main parts of the application Launcher (main application program) and Updater (To download files from server and replace them with the new ones and then launch the new file)
The application will have the option to manually check for update and also to check for update on startup.
If an update is available, it asks the user to apply the update now or later.
If the user selects to apply the update now then Updater application is executed in a separate process and then Launcher application is closed from within the code in Launcher. I have following approaches in my mind to launch another program from within first one and then exit:
Execute the Updater directly from within the Launcher using Process.Start
If that causes problem then as second approach launch command prompt from Process.Start, execute another program (Updater) from command prompt, close the command prompt and then exit the Launcher.
The Updater application then downloads all the relevant files from the server and upon completion old application files are replaced with the new ones.
Update availability information from server will include the new Version_No of application. For the purpose of providing all files for update, I will compress (zip) all of them in a single file named as Application.Version_No (as given by the server).
Upon download completion decompress (unzip) them to a folder named as the same Application.Version_No.
After decompressing all the files in this (Application.Version_No) folder will be copied to the Bin folder of application.
The new application Launcher file is executed in a separate process and Updater application is closed from within the code in Updater.
I have NOT yet tried this scenario as currently my focus is on completing the main application, but surely this must work.
UPDATE:
Another approach to check for updates is to use a bootstrap like application startup. It will be the main entry point of the program. Upon execution it will check for the updates and if there is none the Launcher is executed otherwise it will download the files, replace the old ones and then execute the new / updated Launcher.
For copying / overriding the files
One approach is to include only those files in the compressed (zip) file which are required to be replaced with the old ones and then after the download completes, either directly decompress them to the Bin folder or decompress them to a designated folder and then copy all of them to the Bin folder.
As another approach which seems somewhat lengthy, an additional helper file (XML, text or any other format) could be prepared for the download.
This helper file contains information of updated files like version number of each file, location where these are to be copied etc.
The files may be downloaded to a specific folder named as the new application version.
After downloading all the required files to a specific folder process each file mentioned in the helper file. Compare version of every old file with the new downloaded file. If it is latest then replace it in the folder mentioned in the helper file.
As another step in between all the downloads may be verified prior to copying and replacing.
Built an updater that ships with a daemon. Main project here:
https://github.com/UVLabs/dotNetUpdatify
There should be a way to eliminate the use of the daemon, if i figure it out i will update.
I want to server a Dart application on an Apache server. I added the line
application/dart dart
to the mime.type file in the Apache configuration. Still I get the error
Resource interpreted as Script but transferred with MIME type text/plain: "http://localhost/~d022051/mastermind/web/mm-game.dart".
Another issue is the link to the packages directory. I do not want to have symlinks in the documents directory of the server. Is there a smart way to copy the required packages in the correct version?
This message has nothing to do with Apache.
It's a while that I worked with Apache, but as far as I know you don't need specific settings to serve a Dart client app using Apache. They are just like any other static HTML, CSS, JavaScript, or image files.
You get this message because the entry page (index.html) contains a script tag for a Dart script. After you run pub build there are no Dart scripts (yet) in the build output (this will change when Chrome supports Dart and pub build also generates Dart output).
When the browser finds this (currently redundant) Dart script tag it produces this output. When you want to get rid of this message just remove the script tag from the HTML page in your your_app_package/build/web/index.html file.
EDIT
transformers:
- $dart2js:
'minify': true
commandLineOptions: ['--output-type=dart']
or
commandLineOptions: ['--output-type=dart', '--categories=Server']
I haven't tested if this categories argument has an effect in dart2dart too.
EDIT END
EDIT2
There is also the output type dart-multi which creates one output file per input library.
See https://code.google.com/p/dart/issues/detail?id=21616#c9 for more details.
EDIT2 END
Add the following lines to the pubspec.yaml file of your package (thanks to Günter, who pointed this out):
transformers:
- $dart2js:
'minify': true
commandLineOptions: ['--output-type=dart']
Then run pub build with the option --mode=debug.
This results in a "runnable" Dart application, containing the dart sources and the needed packages. The build directory can then be copied to a location visible to your web server. When loading the corresponding URL in the Dartium browser the application is started.
