Ev2 and text deltas
Quick question: is there a method via Ev2 to set text deltas? I see
svn_editor_set_text(), but that appears to just apply full texts to
the target (via the given stream), rather than text deltas. This
seems odd. Why wouldn't we use text deltas instead of a simple
stream?
Also, after reading the docs in svn_editor.h, it feels like all text
contents are sent in 'postfix' mode. In other words, in Ev1, we have
the following sequence of calls:
open_file()
close_file()
...
apply_textdelta()
Whereas in Ev2 we have:
add_file()
...
set_text()
Just trying a bit harder to grok Ev2,

Make sure you see my rough-thinking in notes/editor-v2.txt, too.

Yes, that thread was quite illuminating. I'm just doing some poking
of Ev2, attempting to see how much more of it I can grok.

Hyrum -- was your question answered? In particular, my thoughts around
using set_text() rather than deltas is best explained by this message
in the thread Stefen referenced:
http://svn.haxx.se/dev/archive-2009-09/0307.shtml
Let me know if there is more that I can help with.
