ProcessBuilder clean up

- Code cleanup
- Added create() static method for easy creation until we can do `$process = (new ProcessBuilder())->add()->getProcess();`
- Removed windows wrapping of commands. This does not belong there IMO. If assetic needs that it should add it, and if it's generally beneficial to everyone then we should add it to Process, but having it implicitly only when using ProcessBuilder makes on sense.

---------------------------------------------------------------------------

by beberlei at 2012-02-16T16:10:15Z

I agree on the windows stuff. I know it fixes a bunch of issues in Assetic, but it also caused my tons of headaches in my windows commands that didnt need strict escaping. Also this messes with parameters in Powershell for example, when you have "foo /bar:baz" then it makes this to ""foo" "/bar:baz"" which in some circumstances fails. Its all messy.

---------------------------------------------------------------------------

by schmittjoh at 2012-02-16T17:53:30Z

Can you move the wrapping to the Process class instead? It's generally causing no bad side effects, but fixes a few issues in the proc_open implementation. It is also necessary for Assetic, and potentially other tools to work on Windows.

---------------------------------------------------------------------------

by Seldaek at 2012-02-16T17:56:02Z

Sure, although "generally" sounds a bit scary in your sentence :)

What about the bypass_shell option?

---------------------------------------------------------------------------

by schmittjoh at 2012-02-16T18:02:12Z

"generally" means I don't know of any, but what I do know is that the alternative you are suggesting is not working. Have there been any bug reports on Assetic/symfony/your own code that "cmd" wrapping causes problems?

---------------------------------------------------------------------------

by Seldaek at 2012-02-16T18:04:59Z

No no, don't get me wrong, I'm not suggesting this should be removed. I'm just saying it should be done for all processes or none, but not just for those run via the ProcessBuilder because that's a good recipe for WTFs.

---------------------------------------------------------------------------

by schmittjoh at 2012-02-16T18:09:38Z

Yeah, I understand, and it makes sense.

What I would suggest is to move it to the process class, and let a wider audience test this to see if we get any bug reports on strange behavior etc.

---------------------------------------------------------------------------

by Seldaek at 2012-02-16T18:12:00Z

Still not sure about the bypass_shell option though. And @beberlei mentioned problems? Can you expand on that?

---------------------------------------------------------------------------

by Seldaek at 2012-02-16T18:16:34Z

Added back to Process, with a switch so if anyone runs into problems they can easily disable it.

---------------------------------------------------------------------------

by Seldaek at 2012-02-22T10:59:58Z

Ping @fabpot - I think this is ready now
Ping @kriswallsmith if this gets merged please update Assetic stuff to restore the bypass_shell option if it's really needed.

---------------------------------------------------------------------------

Posting a PR under "code cleanup" that tinkers with a class that is inherently difficult to test for regression and has been tested by the community for over a year is… a bit hard to swallow, honestly. Everything is there for a reason and should not be tinkered with lightly.

For example, it's important that the `$env` variable default to `null` so the current environment is inherited by default — why change that?

I don't know what the `bypass_shell` option does, but @pierrejoye does… which is why he put it there.

I'm okay with adding an "enhanced Windows compatibility" switch, but I personally think is should be on the builder, not `Process`. The builder is where we manipulate the strings that compose the command line, not in `Process`. You're introducing manipulation of the command line to `Process`, which blurs the responsibilities of the two classes.

I'm also okay with the static factory method :)

---------------------------------------------------------------------------

by Seldaek at 2012-02-22T13:19:40Z

@kriswallsmith (Sorry about the confusing title) My concern is just that if you use Process then decide to "upgrade" to the ProcessBuilder, you suddenly have a change of behavior that might break stuff without you noticing. I just want to avoid this unexpected behavior.

As for the $env stuff, I added a couple tests now, and then expanded that ternary operator a bit.. It actually was broken before. It passed null if you had no env set, but even if you did not call `inheritEnvironmentVariables`. If you want to inherit by default - which I agree it should - then why was `inheritEnv = false` in the constructor? I changed it too and now there is hopefully less confusion.

Restored bypass_shell=true unless it's explicitly set to false.

---------------------------------------------------------------------------

by kriswallsmith at 2012-02-22T13:25:23Z

We should also add the PHPUnit `@backupGlobals enabled` annotation while we're in here.

---------------------------------------------------------------------------

by kriswallsmith at 2012-02-22T13:31:41Z

@Seldaek Looks better, thanks for the changes. If `enhanceWindowsCompatibility` is going to live on `Process` we should expose the switch on the builder as well. Speaking of `enhanceWindowsCompatibility`… is there a more descriptive name for that? What exactly does that do, any why would anyone want to switch it off? The name is so vague we might as well call it `enableMagicalWindowsFix()`.

---------------------------------------------------------------------------

by pierrejoye at 2012-02-22T13:33:55Z

I really do not think that having a flag to enable portability is a
good idea, at all.

I do not remember the context right now but a flag is definitively a
bad idea (you will need other on other platforms).

I will take a look again at this next week (end of), as I am still OOF.

backupGlobals seems to be enabled by default.

As for the enhanceWindowsCompatibility, yes. It's a poor name, but no I don't have any idea for a better one, because nobody could explain me what it does. People just scream that it's necessary.

@pierrejoye: If you or anyone can conclusively confirm that this stuff is always better, then we always do it. If it's not then it must be optional, and if it's not a flag then what? The point of the component is to abstract the proc_open horrors. If people have to know about windows quirks with regard to proc_open to use it, then it's not a very useful abstraction.

Additionally, if it *is* always better to use those portability fixes, then why isn't php doing it itself?

proc_open has many quirks, not only on windows. That's why it should
work and detect what is needed, that may force you to slightly change
the split between builder and process.

> Additionally, if it *is* always better to use those portability fixes, then why isn't php doing it itself?

BC, like it or not (I do not).

However we cannot change past versions, so today code has to deal it
with it anyway.

I will take a look at what you are trying to fix here next week, if
you have any other requests regarding proc_open&portability, let me
know :)

Cheers,

Ok so it sounds to me like the current code is correct, it tries to fix
things as best as we know how to by default, and just gives you a way to
disable things in the odd case we messed up and some of those fixes are
harmful to some use cases.

---------------------------------------------------------------------------

by kriswallsmith at 2012-03-02T21:42:22Z

I'm still not happy with the name of `enhanceWindowsCompatibility`. We need to be more specific about what that does. It sounds like a marketing term right now ;)

---------------------------------------------------------------------------

by Seldaek at 2012-03-05T13:44:56Z

Agreed, but I can't think of anything better. It is indeed esoteric magic fixes that should work better but nobody seems 100% sure about it, so I think it's fairly accurate.

[Security] Implement support for CSRF tokens in logout URL's

```
Bug fix: no
Feature addition: yes
Backwards compatibility break: no
Symfony2 tests pass: yes
Fixes the following tickets: -
Todo: -
```

[![Build Status](https://secure.travis-ci.org/jmikola/symfony.png?branch=logout-csrf)](http://travis-ci.org/jmikola/symfony)

This derived from #3006 but properly targeting on the master branch.

This exposes new configuration options to the logout listener to enable CSRF protection, as already exists for the form login listener. The individual commits and their extended messages should suffice for explaining the logical changes of the PR.

In addition to changing LogoutListener, I also created a templating helper to generate logout URL's, which includes a CSRF token if necessary. This may or may not using routing, depending on how the listener is configured since both route names or hard-coded paths are valid options.

Additionally, I added unit tests for LogoutListener and functional tests for both CSRF-enabled form logins and the new logout listener work.

Kudo's to @henrikbjorn for taking the time to document CSRF validation for form login listeners (see [here](http://henrik.bjrnskov.dk/symfony2-cross-site-request-forgery/)). The [Logout CSRF Protection](http://www.yiiframework.com/wiki/190/logout-csrf-protection/) article on the Yii Framework wiki was also helpful in drafting this.

---------------------------------------------------------------------------

by jmikola at 2011-12-31T07:50:31Z

Odd that Travis CI reported a build failure for PHP 5.3.2, but both 5.3 and 5.4 passed: http://travis-ci.org/#!/jmikola/symfony/builds/463356

My local machine passes as well.

---------------------------------------------------------------------------

by jmikola at 2012-02-06T20:05:30Z

@schmittjoh: Please let me know your thoughts on the last commit. I think it would be overkill to add support for another handler service and/or error page just for logout exceptions.

Perhaps as an alternative, we might just want to consider an invalid CSRF token on logout imply a false return value for `LogoutListener::requiresLogout()`. That would sacrifice the ability to handle the error separately (which a 403 response allows us), although we could still add logging (currently done in ExceptionListener).

After rebasing, my merge commits disappeared. Is this normal?

---------------------------------------------------------------------------

by stof at 2012-02-15T00:15:07Z

Are you sure they disappeared ? Diverging from the remote branch is logical (you rewrote the history and so changed the commit id) but are you sure it does not have the commits on top of master ? Try ``git log master..logout-scrf``

If your commut are there, you simply need to force the push for the logout-csrf branch (take care to push only this branch during the force push to avoid messing all others as git won't warn you when asking to force)

---------------------------------------------------------------------------

by stof at 2012-02-15T00:17:09Z

ah sorry, you talked only about the merge commit. Yeah it is normal. When reapplying your commits on top of master, the merge commit are not kept as you are reapplying the changes linearly on top of the other branch (and deleting the merge commit was the reason why @fabpot asked you to rebase instead of merging btw)

---------------------------------------------------------------------------

by jmikola at 2012-02-15T00:18:00Z

The merge commits are not present in `git log master..logout-csrf`. Perhaps it used those merge commits when rebasing, as there were definitely conflicts resolved when I originally merged in symfony/master (@fabpot had made his own changes to LogoutListener).

I'll force-push the changes to my PR brange. IIRC, GitHub is smart enough to preserve inline diff comments, provided they were made through the PR and not on the original commits.

---------------------------------------------------------------------------

by jmikola at 2012-02-15T00:19:38Z

That worked well. In the future, I think I'll stick to merging upstream in and then rebasing afterwards. Resolving conflicts is much easier during a merge than interactive rebase.

---------------------------------------------------------------------------

by jmikola at 2012-02-23T18:46:13Z

@fabpot @schmittjoh: Is there anything else I can do for this PR? I believe the exception was the only outstanding question (see: [this comment](https://github.com/symfony/symfony/pull/3007#issuecomment-3835716)).

I haven't checked, but for such things I find it way easier to find them in cookbooks than in the changelog - if you don't mind reformatting/copy that in a docs PR it'd be great.
