Fails to expand keys appropriately. #47

Hi.

My log says ...

12:03:33.535: INFO function error: A BAD KEY WAS PROVIDED/CHARACTERS OUT OF RANGE

I'm using DoctrineCache, so the format of [xxxx][n] is their's. I only supply the xxxx part.

The UI shows ...

What's missing is the expansion of the remainder of the keys.

It would be nice to be able to extend the key splitting with known key generators.

DoctrineCache's structure is %s[%s][%d], where the 3 parts are namespace (optional), key (user supplied and if multi part can have any sort of separation, and version (a number).

I'm guessing other systems generate keys in a different way. Maybe having a UI in Fastonosql that allows multiple splitters as well as ignore string sequences.

So, : and ][ are splitters, but [ and ] are ignored. Hmm. Obviously doing the split then ignore works for this pattern. May not work for all though.

Happy to help in any way I can on this.

The text was updated successfully, but these errors were encountered:

Hi @rquadling, now FastoNoSQL have only (combobox)namespace separator when user create connection, can you describe in more detail how use can input complex namespace separator?

topilski · 2017-10-10T11:58:27Z

Your keys should display like in redis, why i see folder i don't know i need to try reproduce your image.

topilski · 2017-10-10T12:05:33Z

Also if TTL expired, key will removed from tree, but folders can exists.

rquadling · 2017-10-10T12:13:01Z

The cache hasn't expired in my testing. That's part of what I'm using Fastonosql for. To see what is happening in the cache. The error that is generated in the logs tells me something is wrong. I do not know what it is wrong. Our application is operating well with the cache. Our code (PHP based and using DoctrineCache) says we are getting our data from the cache.

Our code only supplies part of the key. The remainder is provided/wrapped by the caching code we use.

topilski · 2017-10-10T12:15:43Z

I will try to reproduce your case, thank you!

rquadling · 2017-10-10T12:17:37Z

If we had the capability of defining multiple separators, then I could add : and ][.

This would then cause the tree to look like

[DT
  categoryController
    tickets
      670
        9532
          0]

And then removing [ and ] would fix the first and last elements, though they could remain if that causes issues.

12:03:19.155: INFO function error: A BAD KEY WAS PROVIDED/CHARACTERS OUT OF RANGE
12:03:33.535: INFO function error: A BAD KEY WAS PROVIDED/CHARACTERS OUT OF RANGE

I fixed this warnings, it was my mistake. About separators, how user can specify this separators in settings, in your case you have 2 pair of separators(: and ][) but if someone will want 10 separators, how i can handle user input?

rquadling · 2017-10-10T12:56:31Z

I would have a string list that they can add entries to, as well as a character removal/clean option.

So. Maybe a UI like ...

Add separator: [          ]     [Add]
Separators:
+----------------------------------------+
| :                             [Remove] |
| ][                            [Remove] |
|                                        |
|                                        |
|                                        |
|                                        |
|                                        |
|                                        |
|                                        |
|                                        |
+----------------------------------------+

Remove from key(s): [          ]

And document that splitting takes place before removal.

So, for me the Remove from key(s): would look like.

Remove from key(s): [[]        ]

This would mean that the DoctrineCache key of [DT:categoryController:tickets:670:9522][1] is treated as a set of DT, categoryController, tickets, 670, 9522, and 1.

topilski · 2017-10-10T12:59:28Z

Thank you for description, i will think about your solution. In current moment you can select separator which not containing in your keys, and working like with common keys.

rquadling · 2017-10-10T13:07:22Z

If you find that there are a LOT of standardised structures, then maybe having a checkbox of supported splits/cleans.

So, maybe ...

Keys generated by
(*) DoctrineCache

Add separator: [          ]     [Add]
Separators:
+----------------------------------------+
| :                             [Remove] |
| ][                            [Remove] |
|                                        |
|                                        |
|                                        |
|                                        |
|                                        |
|                                        |
|                                        |
|                                        |
+----------------------------------------+

Remove from key(s): [          ]

topilski · 2017-10-11T08:27:23Z

Fixed, and new release uploaded, in namespace combobox you can write separators which you want, in your case it will be :[] , all this characters will be delimiters.

I'll get back to you next week - on a different development for a couple of days.

rquadling · 2017-10-16T11:45:38Z

Hi.

Keys expanding correctly now.

I'm using :[]| as my separators and getting ...

But when I try to get the value for any of those keys ...

Logs:

12:36:07.093: GET function error: NOT FOUND
12:36:16.832: GET function error: NOT FOUND

Commands:

[MEMCACHED] 12:36:07.093: GET [DT:categoryController|tickets|659|4110][1]
[MEMCACHED] 12:36:16.832: GET [DT:ticketsController|cats|659][1]

So. Progress!! But still not usable.

topilski · 2017-10-16T13:25:50Z

Hi, thank you for feedback, will continue working on it.

topilski · 2017-10-16T13:32:21Z

Also can you please check if key [DT:categoryController|tickets|659|4110][1] exist in your db?

rquadling · 2017-10-16T13:44:28Z

I've just loaded about 5 more pages which will cache their data.

I am getting very peculiar responses visually in Fastonosql.

I'm now only getting folders. No keys.

Also, a key with a 4 hour TTL is not being presented correctly at all.

[MEMCACHED] 14:41:07.839: SCAN 0 MATCH * COUNT 1000
[MEMCACHED] 14:41:07.847: TTL [DT:all-time-total][1]
[MEMCACHED] 14:41:07.848: TTL [DT:categoryController|tickets|659|4051][1]
[MEMCACHED] 14:41:07.851: TTL [DT:categoryController|tickets|659|4037][1]
[MEMCACHED] 14:41:07.861: TTL [DT:categoryController|tickets|659|4053][1]
[MEMCACHED] 14:41:07.862: TTL [DT:categoryController|tickets|659|4050][1]
[MEMCACHED] 14:41:07.862: TTL [DT:categoryController|tickets|659|4045][1]
[MEMCACHED] 14:41:07.865: TTL [DT:categoryController|tickets|659|4110][1]
[MEMCACHED] 14:41:07.869: TTL [DT:ticketsController|cats|659][1]

The all-time-total is going to be around for several hours. Doesn't display as a key. Only a folder.

Using :[]| as separators.

I wonder if the split is resulting in zero length strings when it gets to ][ in the key?

rquadling · 2017-10-16T14:02:20Z

What is interesting is that SOMETIMES when I load database, I get a key and then it all reverts to folders and no keys.

rquadling · 2017-10-16T14:10:28Z

I've taken a look at the data using ...

memdump --servers=localhost | xargs -L1 -I% sh -c 'echo "get %" | nc localhost 11211'

and got ...

VALUE [DT:all-time-total][1] 0 12

[snipped]

So this is telling me that there is data.

I know the first one will be around for about 4 hours, so is an easy enough test.

The others have a ttl of about a minute, but I can easily modify that.

But memdump is showing me data (though the larger data is compressed).

topilski · 2017-10-16T14:10:36Z

This happens because keys have time to live. in FastoNoSQL if key was removed but have folders, folders will not cleaned.
