QUESTION

remove files with VBA in Tortoise SVN

Asked 2021-Jun-01 at 15:10

I need to delete (remove) files (and possibly folders) via Excel VBA in Tortoise SVN environment. However I change my command, it always deletes the folder where files reside.

Call obj.Run("TortoiseProc.exe /command:remove /pathfile:""C:\someSVNpath\123.txt"" /closeonend:1 ")

Call obj.Run("TortoiseProc.exe /command:remove /pathfile:""C:\someSVNpath\Folder"" /closeonend:1 ")

I was also trying to list files in the loop and delete, but then the error appears: Subversion reported an error: Previous operation has not finished; run 'cleanup' if it was interrupted. Please execute the 'Cleanup' command.

Also, even if I manage to list the files in the loop and delete, the commit operation does not find any files for committing.

I think your main problem is that you aren't waiting for the shell to return. These operations are likely running asynchronously and running over each other. This is a sort of race condition.

I fix this by adding , 1, True to the end of the .Run command. The 1 is a intWindowStyle that "Activates and displays a window. If the window is minimized or maximized, the system restores it to its original size and position. An application should specify this flag when displaying the window for the first time."

The True at the end is bWaitOnReturn indicating whether the script should wait for the program to finish executing before continuing to the next statement in your script.

The way you declared your variables they are all variants. Dim needs a type on each variable. Also Call is deprecated.

QUESTION

Time complexity of divide step in merge sort applied to linked list

Asked 2021-May-22 at 21:29

I have been looking at the application of merge sort to linked lists. Some of the articles I have looked at tout that merge sort is the best algorithm for sorting a linked list. It makes sense for the conquer part in the divide and conquer strategy where you merge the two sorted linked lists as you end up saving on required memory (compared to an array). But, what I don't understand is the time complexity of the divide step in the algorithm.

For an array, this step is constant time by leveraging random access and splitting the array into smaller chunks. But, for a linked list isn't this going to take an additional O(n)? I have seen Floyd's algorithm (tortoise-hare) used to find the mid-point of a linked list and divide the problem into smaller chunks. I did some analysis on the divide step. Suppose the linked list is of size n, then the # of operations involved in just dividing the problem is as follows,

n/2 + n/4 * 2 + n/8 * 4 + ... = n/2 * log(n)

From the above, it looks like compared to the array case, an additional factor of "n" appears from Floyd's algorithm. So, the final time complexity would be O(n^2 * log(n)). Can someone please explain the discrepancy?

Edit: based on @Yves comment, I identified the mistake,

I multiplied the work while merging back the sorted blocks from bottom to top when it should be added. So, the net time would be: nlogn/2 + nlogn = O(nlogn),

This is probably is most valid answer to the above question; other answers are a bit indirect/ provide no explanation

...

ANSWER

Answered 2021-May-22 at 21:29

The issue with your question is that the additional O(n/2) time complexity for the scanning of half a sub-list for each level of recursion translates into an overall time complexity of O((0.5 n log(n) + 1.0 (n log(n)) = O(1.5 n log(n)), not O(n^2 (log(n))), and O(1.5 (n log(n))) translates into O(n log(n)), since time complexity ignores lower order terms or constants. However in my actual testing for a large list with scattered nodes, where most node accesses result in a cache miss, my benchmarks show an relative time complexity of recursive versus iterative to be O(1.4 n log(n)), using a count based scan to split lists, rather than tortoise-hare approach.

For recursive version, using tortoise-hare approach is relatively slow and can be improved by using a count of nodes, which may require a one time scan of n node if the linked list container doesn't maintain a count of nodes (for example C++ std::list::size()). The reduces the overhead to advancing a single pointer halfway (sub-count / 2) through a linked list run.

Example C / C++ code:

Time taken to sort numbers in Linked List

However, in such a case (large list, scattered nodes), it is faster to copy the data from the list into an array, sort the array, then create a new sorted list from the sorted array. This is because elements in an array are merged sequentially (not via random linked list next pointers), which is cache friendly.

It seems the documentation on running tests in Tortoise ORM is a bit off. In the unit test section it mentioned something about using initializer() and finalizer() but these brought only more problems. It seems the real solution is simpler than it looks.

Select reset.
Push

ANSWER

Answered 2021-Feb-27 at 23:36

If you're doing a git reset and you pushed those commits already, you need a force push as you're rewriting history. (side node, to do a force push in TortoiseGit, select the "known changes" checkbox)

But another option is to revert the commits, which create a new commit with the reverted changes.

You could do that as follows in TortoiseGit:

Go to the commit log
Select the commit(s) to revert and select 'Revert changes by these commit(s)'
Those reverts are now in your local branch. So go to the commit dialog to create a new commit.
And just push
