0001 This document describe environment variables you can set to debug Gwenview
0002
0003 # `GV_MAX_UNREFERENCED_IMAGES`
0004
0005 How many unreferenced images (images which are not currently displayed and have
0006 not been modified) should be kept in memory.
0007
0008 Defaults to 3
0009
0010 # `GV_THUMBNAIL_DIR`
0011
0012 Defines the dir where thumbnails should be generated.
0013
0014 Defaults to $HOME/.thumbnails/
0015
0016 # `GV_REMOTE_TESTS_BASE_URL`
0017
0018 Used by documenttest. Define a base url where documenttest will put images to
0019 test loading from remote urls.
0020
0021 If not set, remote url tests are skipped.
0022
0023 Should be set to something like `sftp://localhost/tmp`
0024
0025 # `GV_FATAL_FAILS`
0026
0027 If set, when a `GV_RETURN*_IF_FAIL` method fails, then `kFatal()` will be
0028 called, which makes it possible to stop at the place of the failure with the
0029 debugger and also makes it possible for users to report backtraces if they
0030 experiment those failures.
