annotate src/os/unix/ngx_alloc.h @ 391:1d9bef53cd8e

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Range filter: late_ranges functionality. Add one more filtering point after postpone filter. This allows to serve range capable replies with subrequests. It's not as efficient as range filtering for static data (i.e. doesn't save us from reading data from disk if some filter needs them in memory), but it may save some network bandwidth for us and for our users.
