If start is larger than the end of the list, an empty list is returned. Out of range indexes will not produce an error. In your programming language of choice (think Ruby's Range.new, Array#slice This may or may not be consistent with behavior of range-related functions Return 11 elements, that is, the rightmost item is included. Note that if you have a list of numbers from 0 to 100, LRANGE list 0 10 will Consistency with range functions in various programming languages These offsets can also be negative numbers indicating offsets starting at theįor example, -1 is the last element of the list, -2 the penultimate, and so The offsets start and stop are zero-based indexes, with 0 being the firstĮlement of the list (the head of the list), 1 being the next element and so Returns the specified elements of the list stored at key. Ansible recommends writing logs to secure location in case it contains sensitive data.Syntax LRANGE key start stop Available since: 1.0.0 Time complexity: O(S+N) where S is the distance of start offset from HEAD for small lists, from nearest end (HEAD or TAIL) for large lists and N is the number of elements in the specified range. Loop: ""Īs for now it seems there is no way to implement desired behavior w/o workarounds. You can register output of no_log task and print only non-secret part in subsequent debug: - hosts: localhost There is a way to achieve desired behavior in multuple tasks with ansible's error handling.
Main eponymous function, geodist (), accepts only one or two primary arguments, which must be rectangular objects with unambiguously labelled longitude and latitude columns (that is, some variant of lon / lat, or x / y ). I will weigh the pros and cons to see if I will implement this workaround, or if I continue to use it the way it is now. blah An ultra-lightweight, zero-dependency package for very fast calculation of geodesic distances. That said, I asked for a solution, and based on how Ansible works at the moment, the provided workaround (or some similar workaround) seems to be the only way to achieve what I asked. So the best I could say, is that this is a workaround that solves a problem and creates several others. Changing and testing the existing loop tasks, as well as making any new loops follow this format, will be a maintenance burden (especially because of point 2, that makes me think if I'm actually improving the code, or making it worse).The 2 tasks will be printed unnecessarily when everything is fine (with success messages printed separately from the actual tasks, making the output worse when everything runs successfully, which should be most cases).The loop label in the debug task will be different than the one in the main loop task (which may make it more difficult to associate success and error cases to the actual items).The error and where it shows the error message will be different places.If you have a loop in a parent file, you should use loop_control with loop_var in the debug loop.
Geodist dont print code#
Geodist dont print install#
You have to install the library jmespath prior to running json_query filter.The answer from Vladimir actually works as a workaround, but there are several downsides in using it: So, is there a way to make it not log the loop items when an error occurs, but log everything else? It could be either a task flag, just like no_log, or some global configuration, to include in the ansible.cfg file.
This is similar to stop all logs in a reverse proxy, or log everything, including authorization headers, both of which are far from desired in a production environment. geodist calculates geographical distances by measuring the length of the shortest path between two points along the surface of a mathematical model of the earth. I can hide it using no_log: true, but it then hides everything, including when a sucess happens, as well as the error message, that could be perfectly fine, and making me clueless about the actual error when I don't see it. When I execute an ansible module with a loop that has dictionaries with values to be used by the module, including confidential information, I can hide it using loop_control.label, but not when an error happens.
