serialization - reconstruct python method with kwargs with marshal and types? -

-

i using marshal module serialize python methods, , reconstruct them using types module (is there easy way pickle python function (or otherwise serialize code)?). having trouble getting work optional kwargs. e.g.

import marshal import types  def test_func(x, y, kw='asdf'):    return x, y, kw serialized_code_string = marshal.dumps(test_func.func_code) # in real code there bunch of file i/o here instead unserialized_code_string = marshal.load(code_string) new_func = types.functiontype(code, globals(), "deserialized_function")

when run new_func(1,2) error new_func() takes 3 arguments (2 given), though kwarg optional. think issue arises in reconstructing function func_code, not sure how fix this. if there isn't way, interested in alternative way reconstruct function keeps kwarg functionality.

after more searching discovered dill package, allows pickle more things cpickle (the reason using marshal). when directly reconstruct serialized function (not using func_code), avoid keyword issue having.

PHP DOM loadHTML() method unusual warning -

i had following code works fine on localhost: $document = new domdocument(); $document->loadhtml($p_result); $form = $document->getelementsbytagname('form')->item(0); // code continues using $form variable after same code updated on outside server, loadhtml() failed , issued warning. warning: domdocument::loadhtml() expects parameter 1 valid path, string given in path/name/to/script.php returned null instead of object code pretty gets fatal error. note contents of $p_result absolutely same on outside server , on localhost. but why displays kind of warning , why not work? doesn't loadhtml() expects argument 1 string in first place? why method expects parameter 1 valid path ? just make clear i'm not calling loadhtmlfile() , i'm calling loadhtml() . thanks. you're affected one of php bugs . issue present in php 5.6.8 , 5.6.9. have affected php version on server, , bug-free version on localhost. the bug forbids null

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
