Ran across this while writing a "populate new repo" script, that used
svn cp to copy a set of svn-hooks in place (by definition from one
repo to another.) What happens is that when a file in the source repo
(called "foreign" here) has svn:executable set, the working dir in the
destination (called "local" here) looks right - ls -l shows the +x
bits, svn proplist -v shows the property, even .svn/props-base
mentions it. The commit, on the other hand, doesn't push it to the
repository. This means that the local checkout is now a "persistent
lie" (in that trying to set it there and commit it does nothing,
because it's "already" set.) A fresh checkout of the result shows the
bits missing, though.
I'm doing copy from url to working dir because in practice, I need to
do some variable substitution before pushing the file to the new repo;
that substitution isn't in the script because without it, the bug
still happens.
I've only tested this on "svn, version 1.6.12 (r955767) - compiled Jun
5 2011, 14:55:20" which is 1.6.12dfsg-1ubuntu1.3 from Ubuntu 10.10
(maverick.) Also, while the test is between two locally built repos
with file:// urls, I originally saw the problem going between https://
and svn+ssh:// which distracted me :-) So I'd appreciate if people
who can conveniently do so would test this on newer versions. Thanks.
