So is there any way to acquire those locks only if all of them are available?

No. Not with standard library mutex at least. There is no way to "check" if a lock is available, or "try" acquiring a lock. Every call of Lock() will block until locking is successful.

The implementation of mutex relies on atomic operations which only act on a single value at once. In order to achieve what you describe, you'd need some kind of "meta locking" where execution of the lock and unlock methods are themselves protected by a lock, but this probably isn't necessary just to have correct and safe locking in your program:

Penelope Stevens' comment explains correctly: As long as the order of acquisition is consistent between different goroutines, you won't get deadlocks, even for arbitrary subsets of the locks, if each goroutine eventually releases the locks it acquires.

If the structure of your program provides some obvious locking order, then use that. If not, you can create your own special mutex type that has intrinsic ordering.

Based on my test, I have the same error when I use PUT method.

But PATCH works fine for me.

id should be the organization id or tenant id.

Please get the id first with

Run pod update to update to a more recent Firebase version. Firebase fully supports the M1 simulator since about the 7.7.0 release.

You have the annotation on the method parameter. @Nonnull String userEmail

So it expects that userEmail== null will always evaluate to false and hence no reason to be there in that if check.

Check the following answer regarding the @Nonnull which belongs to JSR 305

305 is about new annotations where you can already put them, which can help provide programmatic visibility into a design by contract system. So that if a certain method is supposed to not return null, or if a certain method is supposed to never receive a null parameter

So if you as a programmer have the confidence to annotate that parameter as nonNull, why shouldn't it report that the check userEmail == null has no meaning? With the annotation is like you inform the compiler that you have the confidence that it will never get called with null.

Annotation @Nonnull is like describing a contract. You don't make contracts which you know could be broken. If you are not sure then remove the annotation. If you are sure then remove the check userEmail == null

The floating of .talent is most likely the culprit. When floating elements the parent looses track of their height, so if you check the dev tools you will most likely find out the divs with the class yui-gf are actually ending there.

Remove the floating and width of the .talent and try using grid on the parent to align its childs in columns.

Alright, it seems I have found a solution.

Here is the save function now:

The issue here was a bit of a red herring. As @CeriseLimón pointed out, calling NewWriter and Close on an existing ZIP archive will necessarily result in an empty archive being added onto the end of the file. In my use case, the solution was to open the file and write it directly to the stream, rather than attempting to read it as a ZIP archive.

The relevant quote from the "specification" is this:

A squirrel program is a simple sequence of statements.:

stats := stat [';'|'\n'] stats

[...] Statements can be separated with a new line or ‘;’ (or with the keywords case or default if inside a switch/case statement), both symbols are not required if the statement is followed by ‘}’.

These are relatively complex rules and in their totality not context free if newlines can also be ignored everywhere else. Note however that in my understanding the text implies that ; or \n are required when no of the other cases apply. That would make your example illegal. That probably means that the BNF as written is correct, e.g. both ; and \n are optionally everywhere. In that case you can (for lark) just put an %ignore "\n" statement and it should work fine.

Also, lark should not complain if you both ignore the \n and use it in a rule: Where useful it will match it in a rule, otherwise it will just ignore it. Note however that this breaks if you use a Terminal that includes the \n (e.g. WS or /\s/). Just have \n as an extra case.

(For the future: You will probably get faster response for lark questions if you ask over on gitter or at least put a link to SO there.)

Is there an easier way to solve this?

If you dispose of MS/Excel 365 (see FILTER formula) and assuming 2 column ranges you can profit from the new dynamic array features by

• Step 1..2 evaluating the Excel formula FILTER (vs. MS/Excel 365),
• Step 3 rearranging the array values of the data range via Application.Index() and
• Step 4 overwriting the original data

as follows:
