[No, I won't be sending 52 patches to the list!]
This series, started last year, has been hanging around because the
time never seemed right to send it to the list. It may still not be
the right time ... :-D
I would like to be able to compile git using '-Wall -Wextra -Werror'
compiler options. In order to see how far away we are from that
possibility, you can build with DEVELOPER=1 along with the additional
settings: 'DEVOPTS=extra-all no-error pedantic'.
That leads to many warnings:
$ git describe
v2.22.0-rc1
$ make >out 2>&1
$ grep warning out | sed -e 's/.*\[-W/\[-W/' | sort | uniq -c
9 [-Wempty-body]
1694 [-Wmissing-field-initializers]
159 [-Wpedantic]
945 [-Wsign-compare]
2821 [-Wunused-parameter]
$
Note that at the beginning of this cycle, the numbers were quite a bit
smaller (and this series was only 37 patches, rather than 52):
$ git describe
v2.21.0
$ make >out 2>&1
$ grep warning out | sed -e 's/.*\[-W/\[-W/' | sort | uniq -c
9 [-Wempty-body]
759 [-Wmissing-field-initializers]
925 [-Wsign-compare]
2732 [-Wunused-parameter]
$
This series removes the, newly introduced, pedantic warnings and
eliminates all 1371 'missing-field-initializers' warnings that
relate to 'struct option':
$ cat out-warn-master.stats
9 [-Wempty-body]
323 [-Wmissing-field-initializers]
945 [-Wsign-compare]
2821 [-Wunused-parameter]
$
Thus, after about six months, I am further away from my target than
when I started! ;-)
This series does not fix any problems or add any new features, so it
is not important (hence the tendency to 'slip'). I don't want to
flood the mailing list with patches that nobody wants, so: is there
any interest in these kinds of patches? If not, I will stop now!
(I have a 2-3 year old branch that addressed the '-Wsign-compare'
warnings, but that is probably beyond salvaging by now :( ).
This series is available from: git://repo.or.cz/git/raj.git with the
branch name 'warn-master'. A trial merge to current 'next' and 'pu'
branches can be found at 'warn-next' and 'warn-pu' branches. (The
merge to 'next' went without problem, and 'pu' only required a fixup
to the builtin/commit patch).
[The 'warn-v2.21' branch shows the previous version of the series.]
What do you think?
Thanks!
