python - Figuring out what REALLY went wrong when an `ImportError` is raised -

-

take django instance, in manage.py:

try:     import settings except importerror:     sys.stderr.write("error: can't find file 'settings.py'...")

seems legit, happens when settings imports non_existant_lib_foo?

well, you're sent on goose chase possible things have done path, etc.

of course can use except importerror e: , print out actual error message, if want catch specific error , give bit of advice, above?

you're left using regexp more or less or, @ best, guessing "right" module failed importing, , display message.

is there better way handle this?

basically problem error message wrong - there other reasons why import can fail, not wrong paths. importerror means "you cannot use module, @ traceback find out why", jumped conclusion.

if want display "can't find file" should file first. imp.find_module that.

c# - Is it possible to remove an existing registration from Autofac container builder? -

-
something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
