annotate src/http/ngx_http_upstream.c @ 4118:dbddec65fdab
Upstream: r->upstream->length type change to off_t.
Previous use of size_t may cause wierd effects on 32bit platforms with certain
big responses transferred in unbuffered mode.
Nuke "if (size > u->length)" check as it's not usefull anyway (preread
body data isn't subject to this check) and now requires additional check
for u->length being positive.
