X-Git-Tag: allmydata-tahoe-1.3.0~30 X-Git-Url: https://git.rkrishnan.org/pf/content/en/service/sitemap.html?a=commitdiff_plain;h=7eb260a9cf6010a74ce8a0f11a19b98d9a95cbb0;p=tahoe-lafs%2Ftahoe-lafs.git versioning: include an "appname" in the application version string in the versioning protocol, and make that appname be controlled by setup.py 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. --- diff --git a/setup.py b/setup.py index 7183b684..acfd1046 100644 --- a/setup.py +++ b/setup.py @@ -302,7 +302,20 @@ class MySdist(sdist.sdist): # _auto_deps.install_requires list, which is used in the call to setup() below. from _auto_deps import install_requires -setup(name='allmydata-tahoe', +APPNAME='allmydata-tahoe' +APPNAMEFILE = os.path.join('src', 'allmydata', '_appname.py') +APPNAMEFILESTR = "__appname__ = '%s'" % (APPNAME,) +try: + curappnamefilestr = open(APPNAMEFILE, 'rU').read() +except EnvironmentError: + # No file, or unreadable or something, okay then let's try to write one. + open(APPNAMEFILE, "w").write(APPNAMEFILESTR) +else: + if curappnamefilestr.strip() != APPNAMEFILESTR: + print "Error -- this setup.py file is configured with the 'application name' to be '%s', but there is already a file in place in '%s' which contains the contents '%s'.
