Buckets v2 check doesn't work on Linux in the test suite (test_aggregate_buckets fails) #134

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
test_aggregate_buckets fails in Serf trunk (2.0) (currently r2221).
(This bug does not occur on 1.3.x branch. Currently all tests pass on 1.3.x 
branch.)

Original issue reported on code.google.com by Arfrever...@gmail.com on 17 Oct 2013 at 10:36

While debugging this issue on Ubuntu 64bit, I've noticed that the problem is 
that the check:
#define serf_bucket_get_remaining(b) \
            ((b)->type->read_bucket == serf_buckets_are_v2 ? \
..
doesn't work.

Looking at the code the read_bucket pointer for aggregate buckets is indeed 
pointing to the serf_buckets_are_v2 function. However, in the debugger I see 
that read_bucket points to "serf_buckets_are_v2@plt". So comparison of function 
pointers doesn't work with gcc on Ubuntu/Gentoo (Arfrever's platform).

This function pointer comparison is fundamental to the serf bucket API version 
check (needed in serf 1.4 for get_remaining and dynamic logging), so to be 
fixed before 1.4.

This is caused by both static and dynamic linking to serf in the test suite.

In this case there are multiple implementations of serfbuckets_are_v2 in 
different modules, with (of course) different addresses.

(I had this problem on Windows before and applied a fix for that, but that fix 
doesn't work on unix)

Updated title with info that it only impacts the test suite per Bert's comment.
