We will not be addressing this for the upcoming CMake 2.8.3 release.
(Unless the existing module maintainer responds, or a new one comes forward to take up the mantle...) |

I'm a bit hesitant to apply the patch suggested by Erik Johansson. My main objection is the fact that the option ERROR_QUIET not only suppresses the error message, but also ignores it. Two effects influenced by one option: not good.
Maybe we should just forget about this ERROR_QUIET option and change the SEND_ERROR into a WARNING?
Besides that, Subversion_WC_LOG(<dir>) will also fail when the <dir> is not a working copy, just like Subversion_WC_INFO. |

I think we should leave this one alone.
I liked your suggestion, Marcel, in this part of that email thread:
http://www.mail-archive.com/cmake@cmake.org/msg26808.html [^]
Leave the existing functionality alone: if a Subversion_WC_* macro is invoked on a non-working-copy directory, then it *should* be an error.
However, adding the ability to detect whether a directory *is* an svn working copy would be absolutely brilliant. (If 'svn info' succeeds, then it is a working copy... otherwise not -- you don't have to look for existence of ".svn" or anything...)
I think we should add a function called "Subversion_IS_WC" that returns true if the directory is a working copy, false otherwise.
And leave the existing functions as is. |

Using 'svn info' to check whether a directory is a working copy or not puts the Subversion_WC_INFO in a somewhat strange position.
On the one hand you argue that invoking any Subversion_WC_* macro on a non-working copy directory should be treated as an error. On the other hand you suggest to use Subversion_WC_INFO -- well, actually 'svn info' -- to check whether it's a working copy or not.
Of course I could implement a Subversion_IS_WC macro that would simply execute 'svn info' and return its result. However, if all I'm really interested in is the WC_INFO stuff, then I'd have to call Subversion_WC_INFO next, which would execute 'svn info' a second time; a bit of a waste. |

I am of the strong opinion that any Subversion_WC_* function should produce an error if called on a non-working-copy directory.
Please preserve the error so that projects expecting a working copy will produce an error if given directories that are not working copies.
Other than that, I don't really care about any further implementation details.
Feel free to fix this as you see fit. |

Just in case someone is still interested, I've attached an implementation of Subversion_IS_WC. |

Thanks Johannes. I will have a closer look at it when I have time, but currently I'm very busy. |

I'm coming late to this discussion, but why not have Subversion_WC_INFO set the variable ${prefix}_FOUND or ${prefix}_NOT_FOUND based on if this is a WC? That would allow all of the state to be externally visible and handled by the caller however they like, and also follows a well established CMake method of doing things. |
