[Pkg-lyx-devel] Bug#879602: [lyx] Broken svn auto-detecion

[Philipp Klaus Krause]

Package: lyx
Version: 2.2.3-2
Severity: important

--- Please enter the report below this line. ---

lyx tries to autodetect if a file is under verison control. When lyx
2.2.3 reads an input file, it recursively checks parent directories for
.svn, .git, etc.

In case it find a .svn directory, it invokes svn info to parse the
output to see if the file is under version control. For svn, the code is
in SVN::findFile in lines 1154ff of src/VCBackend.cpp.

However, there is a bug in checking if a file is in svn. If the file is
in a directory that is not under svn, but a parent directory is under
svn, lyx will invoke svn info. Since the directory itself is not under
svn, svn info will fail "svn: E155007:
'/home/philipp/sdcc-2/build/doc/sdccman.lyx' is not a working copy"; lyx
considers this an error.

This issue makes out-of-tree builds fail. Example: the sdcc manual is a
.lyx file. When checking out sdcc from svn, and then trying to do an
out-of-tree build in a directory build, it fails due to this bug.
