To avoid duplicated ID, each server should record ID last used. Both of compiler sever and web server need this functionality. Thus, it is better to create module.

Explicitly specify obj file name and delete it

Maybe, hash fragment and JS are used.

Even though CPU time is not consumed, a process may block. An example is I/O wait. For Linux, to sue POSIX timer function is a candidate. For Windows, combination of thread, event and wait function may be promising.

• Need to set environment variable

ccf.{html,css,js} are isolated into sub folder.

• Invocation ID should includes compiler server information
  • This information should be added by web server app.
    #6 required. for this task

• Request: source and corresponding invocations
• Invocation: results

Even though compilation fails, compiler server tries to execute and empty result is returned. Thus, client can not recognize execution is not done.

Currently, CCF messages are embedded in compilation/execution results. Maybe unified error handling is necessary.

Currently, web server app uses Plack::App::WrapCGI, though AnyEvent is also used. psgi.streaming is adequate for asynchronous behavior.

• Showed in compilation results.
• Showed in recents

Available variables in configuration are $input and $ouput only. MSVC produces temporary obj file even in making executable directly. May need supply this as the 3rd variable.

Not only period since post but also lines of the code and compiler keys can be shown without additional information

• port
• config file
• explicit environment key
• log

Anyway, by other limitation, output can't be unlimited. However, explicit limitation is better.

• First some lines of the code.
• Compiler key

Purge old data from compile server

Currently, connection to compile server is made for each HTTP request . Now, web server app becomes a PSGI app. So, we can share connection to compile server.

Arbitrary decision: 10KB

Curently, returning status 1 produces the following representation:

CCF: execution failed by status: 0x0100

It may confuse people that execution itself is failed.

Arbitrary decision: 10KB

The current consideration is as follows:

• Parameter passed to sandbox is passed by environment variables
• Parameter passed to sandbox-ed exe is passed by command line parameter

For each invocation on Windows, cmd.exe window pop-ups.

Purge old data from web server app

It is better for future enhancement to store/restore results.

• host key, host, port

Re-initialization might be easier than migration.

#9 required

To adjust parameters, to see results is necessary.

like /results/ID

Ace is here: http://ace.ajax.org/

Towards to #11, each invocation should be distinguishable. Persistent ID is managed in each compile server. Thus, key for each compiler server should be given in, initial, execution of compile server. Web application can check configuration when list invocation in initialization.

Currently, all data are transferred by S3. So, it is stored anyway. Maybe it is implemented by making enable to select listed or not.
