Remove use of deprecated HttpKernel LoggerInterface
Show PHP SAPI in WDT
Handle the deprecation of IntlDateFormatter::setTimeZoneId() in PHP 5.5.

Optionally use the new IntlDateFormatter::setTimeZone() method if it exists.
Fix version_compare() calls for PHP 5.5.

Until PHP 5.5 hits beta, the version number for Git builds is still 5.5.0-dev,
which is less than 5.5.0alpha1 according to version_compare(). This means that
the branches for 5.5 aren't being executed on 5.5 snapshots at present.
moved the logic from HttpKernel in FrameworkBundle to the HttpKernel component
[TwigBridge] added a render_* function to ease usage of custom rendering strategies

Here is the code you need to write when using the regular render
function for an ESI strategy:

    {{ render(path('path'), { strategy: 'esi' })
}}

And the same with the new render_* function:

    {{ render_esi(path('path')) }}
[HttpKernel] added a URL signer mechanism for hincludes
[HttpKernel] added missing phpdoc and tweaked existing ones
[HttpKernel] simplified and enhanced code managing the hinclude strategy
[FrameworkBundle] made some services private
[HttpKernel] made the strategy a regular parameter in HttpContentRenderer::render()
[FrameworkBundle] deprecated HttpKernel::forward() (it is only used once now and not part of any interface anyway)
made the content renderer work even when ESI is disabled or when no templating engine is available (the latter being mostly useful when testing)
moved the deprecation logic calls outside the new HttpContentRenderer class
moved the container aware HTTP kernel to the HttpKernel component
Enhanced the triggering of E_USER_DEPRECATED errors

- Removed useless error handlers around FormEvent as the triggering has
  been fixed in it.
- Enhanced the triggering of deprecation errors for places where the BC
  method provide some user logic needing to be converted to a new way.
- Enhanced the deprecation messages to mention the replacement whenever
  possible.
[PropertyAccess] Extracted PropertyAccess component out of Form
[PropertyAccess] Property path, small refactoring, read/writeProperty to read/write Property/Index.

In edge cases `getcwd()` can return `false`, then `proc_open()` should get `null` to use default value (the working dir of the current PHP process).

I guess that this could be related to #6496, as error code `267` at Windows means:
[`ERROR_DIRECTORY - The directory name is invalid.`](http://msdn.microsoft.com/en-us/library/ms681382%28v=vs.85%29.aspx#error_directory)

If null already uses the current working directory, what's the point of calling getcwd() at all?

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

@Seldaek TBH. I don't have idea =) It seems that it's there _from the beginning_, but yeah, I was a bit confused by usage of it too...

What about removing the code altogether?

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

by stloyd at 2013-01-09T08:22:55Z

@fabpot I'm ok with that, just not sure it will not be an BC break...

php.net says `or NULL if you want to use the default value (the working
dir of the current PHP process)` which sounds like getcwd() to me.

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

For full BC though, `getWorkingDirectory` should `return $this->cwd ?:
getcwd();` Then at least if that call fails the whole process isn't
failing. I don't see why anyone would use that getter though.

@fabpot @Seldaek What do you think about this now?
