Hello everyone,
I’ve noticed that the subversion module always reports changes when updating, even though my repo (with svn:externals) has not changed.
It was linked to the way the module detects local modifications. The call to “svn status” has no formatting options, and a regexp tries to
detect lines that correspond to a real local modifications (actually, all it does is discard ‘?’ lines, non-versioned files). But there are others
“svn status” codes that should be discarded ( ‘X’ and ‘I’ see {1} ).
More over, when a repo has externals, “svn status” output will no be easily parsed, because some text lines appear :
“Performing status on external item at …”.
The solution I propose is to use the --quiet option for svn status, it makes the output parsing-friendly, and only output anything if there are
local changes, which is exactly what is wanted here.
As a consequence, there is no more need for a regexp, only test if the output is empty.
Here’s a pull request that fixes this {2}.
Thanks in advance.
