This series fixes a few issues with parsing in fast-import, dating back to
git-2.6.0. The only change since v1 is removing the RFC label; sadly, no
one commented on the first round.
Text from my original submission:
The point behind this series is that fast-import somehow mishandled
get-mark directives after empty orphan commits. Digging into it, I
think it was caused by following a precedent set by a somewhat unsafe
implementation of trying to allow cat-blob directives to appear in the
middle of a commit. My spelunking showed the following commits seemed
to be the most relevant as to how we got to the current state:
777f80d7429b ("fast-import: Allow cat-blob requests at arbitrary
points in stream", 2010-11-28)
8dc6a373d201 ("fast-import: add 'ls' command", 2010-12-02)
97313bef2a16 ("fast-import: use skip_prefix for parsing input",
2014-06-18)
28c7b1f7b7b7 ("fast-import: add a get-mark command", 2015-07-01)
I have a few patches that fix the issue and I think make the parser
more robust against future issues in a way that I think is safe enough
for backward compatibility, but "backward compatible enough" might
concern some folks; if so, please take a look at patches 4 and 5.
