Can we leave the throw statement as is and add the leave() call right before is like this:
$this->leave(__FUNCTION__);
throw new StorageNotAvailableException($e->getMessage(), $e->getCode(), $e);There was a problem hiding this comment.
no, because these exceptions are sometimes swallowed, eg. by the availability wrapper: https://github.com/owncloud/core/blob/master/lib/private/Files/Storage/Wrapper/Availability.php#L53.
leave() detects an exception and also logs a stacktrace which is the most interesting thing when debugging this.

Then:
$e = new exception
This->leave(function, $e)
Throw $e

we could do that but it only adds an unnecessary variable.

and adds more structure to the code. 😉

@jvillafanez @DeepDiver1975 thx for the quick review! I updated the PR accordingly. |

I'd also check that the 'password' key exists, so the log won't interfere with the normal flow. If somehow the 'password' key is missing, I guess the log below won't be shown and the expected exception won't be thrown.

empty does not log a warning when an arrey key is not defined: http://stackoverflow.com/questions/20531397/workaround-for-isset-array-key-exists-and-empty

I guess it's fine. I'd add a comment because it's confusing for me: I'd expect the code to explode trying to access to a missing index.
If there are no more pending changes let's go with this as it is. Don't bother to add a new commit just for adding a comment 😄

empty() works fine for unset keys however there is kind of a false positive when checking with empty(): it will return true when checking an array key that has been set to 0 or "0". But I can live with that.

@butonic scrutinizer is reporting 24 new issues - mind taking a look? THX |

I'll kick jenkins |

Scrutinizer does not know where to find the used exceptions. Dunno why he finds those problems now ... not an issue IMO. |

To debug windows network drive issues we need traces. Unfortunately, installing xdebug is not always an option. being able to swith it on via a command line switch is a big win. We did it for 8.2 while debugging a problem. This PR brings the logging part to master.
The
leave()andswallow()could be pulled up to the Common Storage or moved to the ILogger api. For now, having it in smb should suffice. We can move it to core if it turns out useful in other places.cc @felixboehm @DeepDiver1975
