Automate version upgrade - Script Breaking Changes

[Iczer 13]

Script Breaking Changes is the pain especially when you scripts are big.

I wanted some automation to process 3.3.10.2 --> 3.3.12.0+ so i write this. I'm do not use Excel UDF, but other than it, function that needed correction was only "_ArrayUnique" from Array UDF...

Am I right? Or there are more to it?

Also maybe someone can make additions to script

I have not looked at your code.  Just want to comment then wait for the powers that be to comment.  A script that fixes others with your intent has been done before several years back on a major update and it was a godsend.  So I hope this goes just as well if needed.

I just updated autoit last night, I was not aware of the script breaking stuff.  Hm...  I've peeked at it just now and it seems extensive.  I have a couple major Excel scripts for work but its only a small handful.  I was also still learning it so I'm not to concerned about looking them over.  I'm sure the new stuff will help with alot of the limitations I had run into.   The Array UDF on the other hand.    ......... really.  I think every 4th line in pretty much all my scripts deal with arrays in some way or another.  Everything will be broken.  I'm just glad I only updated my home computer so far.  That would have been bad if I had done the work one.  I'll have to compile a bunch of existing stuff so things still work on it and then I will make mods as I go.  I agree that 2D stuff was missing from most things.  To the point where I have a couple UDFs that I wrote that have several functions to deal with 2D stuff that I use all the time.  Having the experts redo that stuff is good.  I just hope I survive the changeover.

But before I go looking through all my scripts I want to ask a quick question.

I looked at the list of functions that have had changes to them but it does not tell me if its a script breaking change or not.  Is there a list of functions that are broken if unchanged in our scripts.
For example the first one on the list says.

_ArrayAdd Now supports 2D arrays and can add multiple lines in one call.

This tells me it has new functionality.  But does it still work as it was?  I can learn the new stuff as I go.  But what I think would be useful for people is a list of functions that we need to go look at right now to make our scripts work again.  If the new functionality is from new parameters on the end but the existing ones still work as is, then this function is not broken, its just better.  I can check out the new stuff as needed.  If on the other hand, the order of the existing parameters has changed,  or one is inserted/removed in the existing parameters then this is a function that will break my scripts and I need to go look at it first.

Looking at the script above its just _ArrayUnique as far as the array UDF is concerned.  But I doubt that's the case or there would not be all the warnings I now see.  It would have been just a "hey look out for this one function" note instead.

Is there a short list of functions that will break existing scripts that we should be looking at first?

...

My first note that something was wrong tonight.  A warning mesg that a file did not properly delete and that it would wait till the file was no longer in use before continuing.   Nothing odd till I realized that usually this is caused by my backup kicking in and locking the file.  However, I set the backup to run later at night instead of continuously a few days ago.  It should not have the file in use at the moment.

I discovered a couple of archive directories for tvshows suddenly got emptied.  A bit of further looking and it seems I have a script where _ArrayUnique should be retuning a list of files to delete from a source directory is instead returning the list of destination directories where the files should have been moved to.  A list that then got used by a delete command.  It removed the files fine but could not remove the directory,  so it thought my backup was currently using it and patiently kept trying.

Thank goodness for backups so I was able to restore the missing files. 

Another example.  I'm guessing _arraydisplay has changed but not in a breaking way.  I have a function that calls _arraydisplay and then resizes the internal cols and window size to center and display a nicer layout based on content. Sort of calling itself as well to get around the fact that _arraydisplay halts the original script while its showing.  This still works, but it now has a couple extra buttons on the bottom.  so this would be an example of a changed but non script breaking function and so NOT on the short list I'm looking for.

Is it really that hard to read the script-breaking part of the release notes?

Help file > Appendix > History / ChangeLog > hit link

History

IMPORTANT: See here for recent script-breaking changes.

[Melba23 2,706]

cal,

 

The Array UDF on the other hand. ......... really.

In the Help file for v3.3.12.0 we tell you straight off (you even get shown this during the install):

Changed: Re-wrote Array UDF to add 2D support and add some functions. THIS IS A SCRIPT BREAKING CHANGE.

And then you can find on the History page:

 

Script Breaking Changes in Recent Versions

This page contains a list of all changes made in recent updates that will almost certainly break existing scripts. Please read this list carefully when upgrading if you have not been keeping up with developments in the beta versions. If any of these issues affect you then you will need to modify your scripts.

1st June, 2014 - v3.3.12.0

UDFs:

[...]

•Array UDF was re-written. Functions and/or parameters have been changed, removed or added. A detailed list can be found here.

[...]

Clicking on the link takes you to this page which sets out in detail exactly what changed.

How much more do you expect us to do?

I will never understand the complaining that goes along with each release. Changes to the core language (any language), always come with growing pains. Don't like the changes? Stick with Java 1.3.1_08, C# 3.0, or AutoIt 3.3.8.1. But your unwillingness to put forth the effort to keep up to speed hurts only yourself and your own efforts at coding.

[cal 1]

Wow.  ok.  I think you guys misread my intent.   Whos complaining?  I even say more then once that I'm sure the updates will be a good thing.  I did read those pages.  My example was even from that page.

That page may say script breaking changes across the top but a quick look shows that is not the case with every function listed.  Its a page of all the changes we need to be aware of.  I was simply wondering if there was a short list of just the actual breaking ones.

Now that I'm at work and have my old help file let me look at that same one using my old help file vs the new help file thats online I will try to be more clear as obviously I was not the first time.

for example.

_arrayadd.

looking at both help files.  I see it returns the index of the last added item.  the First parameter is a reference array and the second parameter is a value.   This is the same for both versions.  The error codes are different but I'm not concerned about that at the moment.  The new ones value can still be a single value like the old version so there is nothing breaking there.   The new ones value can also be a delimited string or an array.  Great.  thats new but has no effect on a script expecting a single value.   The new one can also take additional parameters to do other things.

Great.... I'd call that an enhanced function.  Not a script breaking one.  I'm all for it.  As an enhanced but not script breaking, this function would not be on the short list I was asking about.   If there is no such list then that is fine.  I will create it so I know what I need to fix to make my old scripts work before I go back and look at the full list and the enhancements.

Of course thats just the first one and I'm gong by just the help notes.  I will have to test that before I add or do not add it to my short list.

Again.... Updates are good.  It was a simple question that I think was misunderstood.  No complains here.   As far as effort..... so I don't post my stuff here often.  I'm not known here.  There are people who do know my work.  Lack of effort is not an issue.

Cal.
