[libvirt] [PATCH] RFC: maint: Sort public symbols within a release
Eric Blake

Fri Jun 21 19:18:23 UTC 2019
In libvirt_private.syms, we have a policy of keeping blocks of symbols
sorted by name - in fact, we enforce it during 'make check' with our
check-symsorting rule calling out to a perl script. But
libvirt_public.syms has been more cavalier over the years.
21 releases have been trivially sorted due to adding only one symbol;
while the following 27 releases listed multiple symbols in
alphabetical order, even if the symbols were not chronologically added
in that order [1]:
0.0.3 0.9.5 1.1.0
0.3.0 0.9.7 1.1.1
0.3.3 0.9.8 1.2.5
0.4.2 0.9.9 1.2.8
0.6.3 0.9.10 1.2.11
0.7.5 0.9.13 1.2.15
0.9.0 1.0.1 1.3.3
0.9.2 1.0.2 3.1.0
0.9.3 1.0.3 3.4.0
[1] Case study: git log -p v0.9.9..v0.9.10 src/libvirt_public.syms
shows 9 commits adding 9 APIs among 7 authors:
0b7ddf9e - trivially in order
adb99a05 - appending happened to also be sorted order
1f7aa0ac - irrelevant (removing TABs, not adding symbol)
6714fd04 - added in sorted order
8f8b0802 - appended, out of order
e1eea747 - re-sorted previous addition, and added in sorted order
02af3e13 - added in sorted order
c471e55e - added in sorted order
99fd69c3 - added in sorted order
The following patch changes the remaining 37 releases to do likewise,
and documents the practice.

I'm not sure if we want this patch - it got much bigger than I was
expecting. 37 releases is less than half of the total versions in the
file, but larger than the number of releases that were sorted (where
it is not even obvious if that was always intentional or by luck). We
could also decide to adopt a policy of listing symbols in the same
order as remote_protocol.x (although not all symbols go over RPC), but
that seems like it would be even more churn and harder to enforce.
Ideally, if we DO want this patch, we should also teach 'make check'
via src/check-symsorting.pl how to enforce it on the public file; as I
did not do that, this is marked RFC.
The diffstat shows a delta because I deleted 5 blank lines and added
2 comment lines.
