5c7a649001 fix test suite for metadata changes 
added a few more .copy() calls
 2019-11-28 15:59:09 +00:00
John Cupitt
acd9101037 always copy before exif_update 
During write, we often call vips__exif_update(). This updates the exif
block from the other image metadata prior to save.

Always copy the image before calling this.

20cee5d041 block metadata changes on shared images 
If images are shared (ref count > 1), block changes to the set of
metadata items on the image. These can cause crashes in highly threaded
programs.

9a193f6f4c test for gio 
It seems glib added gio in 2.15, though I don't know if svgload will
actually work with a glib that old.

09325600ee rename VipsStreamib as VipsBufis 
The VipsStreamib (stream input buffered) was misleading -- it was
implemented on top of VipsStreami, but was not a subclass.

Rename as VipsBufis (buffered input stream). It's a silly name, but
easy to remember and reflects the purpose better,
