In the rebar.config files for the gpb and protobuffs inttests, use the
{Name, Version} dependency form instead of {Name, Version, Source},
since the Source is not really applicable; the mocks are copied into
place by the proto_gpb_rt:files/0 and proto_protobuffs_rt:files/0.
Idea and suggestion by Tuncer Ayaz.
Installation of the gpb and protobuffs mocks, in inttest, is now done
using copy in proto_{gpb,protobuffs}_rt:files/0. Previously, rebar
prepare-deps was used, the dependencies had an rsync source with a
relative path back to the inttest directory. This eliminates a
dependency in inttest to rsync, instead relying on retest's
functionality to copy files and directories. Also, it eliminates
hidden knowledge about the directory layout that retest chooses.
Idea and suggestion by Tuncer Ayaz.
Since the dependency sources in the inttest rebar.config files are no
longer used, they are now changed back from rsync paths to git urls,
to serve as examples.
In inttest/proto_gpb, replace the external dependency to gpb, a
protocol buffer compiler, with a simple mock.
The mock provides enough of what is needed for inttest only,
which is to generate some dummy content, but with proper file names.
As a result, the increased timeout for the proto_gpb inttest should no
longer be needed (inttest/proto_gpb/retest.config), both since the
mock is now much faster to compile, and since any network bandwidth or
connectivity issues have now been eliminated.
This reverts commit 81063d33f0, reversing
changes made to 6584defdda.
This was reverted because it changed the gpb compiler to
not use rebar_base_compiler. That change was to add support for
target name prefixes, but it is better to add that support to
rebar_base_compiler.
On my slow old netbook with a 1.6GHz CPU, this inttest
takes about 40 seconds to run, of which network activity
is about 3s, the default timeout of retest is 30s.
Add a generous margin to avoid unnecessary timeouts.
For protocol buffer files, when there were gpb options to alter the
module name with prefix or suffix, recompilation was not properly
detected. This is now fixed. (Issue #384).
Properly detecting change meant moving from rebar_base_compiler, so it
also meant processing protocol buffer files in sequence instead of in
parallel.

The bulk of these tests are written by Luis Rascão, hence he is the
author of this commit. As the committer, I have cherry-picked his two
commits 4c87bcd and ebb8182, from the feature/support_gpb_protobuf
branch in the git://github.com/lrascao/rebar repo, and have slightly
adapted it to fit this pluggable-proto-compilers-gpb branch.
