Hi Junio,
I happened to be building git on an _old_ laptop earlier this evening
and gcc complained, thus:
CC http.o
http.c:77:20: warning: ‘curl_no_proxy’ defined but not used [-Wunused-variable]
static const char *curl_no_proxy;
^
The version of libcurl installed was 0x070f04. So, while it was fresh in my
mind, I applied and tested this patch.
ATB,
Ramsay Jones

Mind including this in the commit message? Especially the error message
can be very useful.
With or without such a commit message tweak,
Reviewed-by: Jonathan Nieder <jrnieder@gmail.com>
This variable has been unused in the old-curl case since it was
introduced in v2.8.0-rc2~2^2 (http: honor no_http env variable to
bypass proxy, 2016-02-29). Thanks for fixing it.
Sincerely,
Jonathan

Makes sense. This #if would go away under my "do not support antique
curl versions" proposal. I haven't really pushed that forward since Tom
Christensen's patches to actually make the thing build (and presumably
since he is building on antique versions he can't turn on -Werror
anyway, since IIRC it tends to have some false positives).
I agree with Jonathan that this explanation should be in the commit
message. The patch itself looks OK, although:

I'm not sure whether our ordering of these variables actually means
much, but arguably it makes sense to keep the proxy-related variables
near each other, even if one of them has to be surrounded by an #if.
I guess you were going for ordering the #if's in increasing version
order. I'm not sure the existing code follows that pattern very well.

Yes, I suspected this would be removed by your proposed update (hence
the cc:), but I didn't know what the ETA on your patches was. Is this
worth doing, or are you about to re-visit that series?

Yes, that was the idea, but I was already in two minds about that!
In the end I went with this, because not all of the proxy variables
are together anyway. ;-) (see, for example, 'proxy_auth' and
'curl_proxyuserpwd' around line #113).
So, I don't mind placing the #ifdef around the current definition
(rather than moving it up), if you would prefer that. (It will have
to be tomorrow, since I have put that laptop away now!).
ATB,
Ramsay Jones

I wasn't about to revisit it. I wasn't sure if we actually wanted to
proceed or not, since Git _does_ actually build now with the old
versions (and there was some minor grumbling about dropping
compatibility).

I'm OK with it either way, then. Thanks.
