munmap_chunk(): invalid pointer Error while making an Array data structure in C++

Asked 2021-Jun-03 at 07:43

I tried going through many similar questions regarding munmap_chunk(): invalid pointer errors, but I'm stuck as to what to do. I tried adding free commands too.

I'm a C++ novice and normally use Python and Java, so the whole concept of pointers and memory management are new to me. It would be great if someone can explain what I'm doing wrong.

Here is my code for my Array class for a generic T:

QUESTION

How to pass parameters loaded from configuration file to a procedural macro function?

Asked 2021-May-16 at 16:16

Here is a problem I am trying to solve. I have multiple procedural macro functions that generate tables of pre-computed values. Currently my procedural macro functions take parameters in the form of literal integers. I would like to be able to pass these parameters from a configuration file. I could re-write my functions to load parameters from macro themselves. However, I want to keep configuration from a top level crate, like in this example:

...

ANSWER

Answered 2021-May-16 at 16:16

gen_table1!(myparams!()); won't work: macros are not expanded from the inside out, like function calls. Your gen_table1 macro will receive the literal token stream myparams ! () and won't be able to evaluate this macro, thus not having access to the "return value" of myparams.

Right now, I only see one real way to do what you want: load the parameters from the file in gen_table1 and gen_table2, and just pass the filename of the file containing the parameters. For example:

ANSWER

Answered 2021-May-16 at 08:38

The overhead is really minimal and shouldn't impact performance at all given the array size is not in thousands. Also, I am assuming you are using set as you are having a lot of checks whether certain element is present in set or not. So it is more like a tradeoff that you are having by using the set.

ANSWER

Answered 2021-May-06 at 06:05

You should try to use a module, but as you say you can not do that, here is how to do it without using one:

from_yaml will parse valid yaml into a dictionary. Your data is not in the yaml-format, so from_yaml does not work.

If you need to use the openssl-command, you will need to use a regex to parse the data. You can do that by using grep in the shell-module or the regex_search filter in ansible. As we want to use as much ansible as possible, I'll show how to do it with a filter:

Reshaping segmented dataframe in R

Asked 2021-May-01 at 15:35

How to reshape a dataframe where data is arranged in "blocks" having width of x columns and length of Y rows. In this example diagram the starting dataframe is two "blocks" wide and three "blocks" long but the solution should work with other dimensions too. The final "block" may have less rows. This data-structure is obtained from the solution posted here: Split dataframe at specifi row and arrange columns into "sections" in R

I tried to reshape with reshape() into long format but could not figure out how to reorder the "blocks".

You don't seem to be restricted in the indexes you can have, so lets assume you have an index on (id) and an index on (status, id). I'm also going to assume that id is a primary key or has a uniqueness constraint, as IDs usually do:
