It is currently hardcoded in setup.py to be 'allmydata-tahoe'. Ticket #556 is to make it configurable by a runtime command-line argument to setup.py: "--appname=foo", but I suddenly wondered if we really wanted that and at the same time realized that we don't need that for tahoe-1.3.0 release, so this patch just hardcodes it in setup.py.
setup.py inspects a file named 'src/allmydata/_appname.py' and assert that it contains the string "__appname__ = 'allmydata-tahoe'", and creates it if it isn't already present. src/allmydata/__init__.py import _appname and reads __appname__ from it. The rest of the Python code imports allmydata and inspects "allmydata.__appname__", although actually every use it uses "allmydata.__full_version__" instead, where "allmydata.__full_version__" is created in src/allmydata/__init__.py to be:
__full_version__ = __appname + '-' + str(__version__).
All the code that emits an "application version string" when describing what version of a protocol it supports (introducer server, storage server, upload helper), or when describing itself in general (introducer client), usese allmydata.__full_version__.
This fixes ticket #556 at least well enough for tahoe-1.3.0 release.
Obviously requiring the code under test to perform within some limit isn't very meaningful if we raise the limit whenever the test goes outside of it.
But I still don't want to remove the test code which measures how many writes (and, elsewhere, how many reads) a client does in order to fulfill these duties.
Let this number -- now 20 -- stand as an approximation of the inefficiency of our code divided by my mental model of how many operations are actually optimal for these duties.
This is important, because if the repairer doesn't completely repair all kinds of corruption (as the current one doesn't), then the successive tests get messed up by assuming that the shares were uncorrupted when the test first set about to corrupt them.
This means that the tests still work if you are executing them from a CWD other than the src dir -- *if* the "bin/tahoe" is found at os.path.dirname(os.path.dirname(os.path.dirname(allmydata.__file__))).
If no file is found at that location, then just skip the tests of executing the "tahoe" executable, because we don't want to accidentally run those tests against an executable from a different version of tahoe.
This is necessary because loading allmydata code now depends on PYTHONPATH manipulation which is done in the "bin/tahoe" script. Unfortunately it makes test_runner slower since it launches and waits for many subprocesses.
This reverses some, but not all, of the changes that were committed in the following set of patches.
