logging - How can I log current line, and stack info with Python? -

-

i have logging function follows.

logging.basicconfig(     filename = filename,     format = "%(levelname) -10s %(asctime)s %(message)s",     level = logging.debug )  def printinfo(string):     if debug:         logging.info(string)  def printerror(string):     if debug:         logging.error(string)     print string

i need login line number, stack information. example:

1: def hello(): 2:    goodbye() 3: 4: def goodbye(): 5:    printinfo()  ---> line 5: goodbye()/hello()

how can python?

solved

def printinfo(string):     if debug:         frame = inspect.currentframe()         stack_trace = traceback.format_stack(frame)         logging.debug(stack_trace[:-1])     if log:         logging.info(string)

gives me info need.

debug      2011-02-23 10:09:13,500 [   '  file "/abc.py", line 553, in <module>\n    rununittest(coverage, profile)\n',    '  file "/abc.py", line 411, in rununittest\n    printinfo(string)\n']

current function name, module , line number can changing format string include them.

logging.basicconfig(     filename = filename,     format = "%(levelname) -10s %(asctime)s %(module)s:%(lineno)s %(funcname)s %(message)s",     level = logging.debug )

most people want stack when logging exception, , logging module automatically if call logging.exception(). if want stack information @ other times need use traceback module extract additional information need.

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.
