Re: BUG #4274: uuid returns duplicate values

I just tried it, slightly better but not a runner....

Here is a sample of the results I get when running my test script, note
result vary but lack of duplicates does not.

Why do you not use the CreateUUID function in windows??

Re: BUG #4274: uuid returns duplicate values

Hi.

uuid of MS is the approach different from ossp. Then, I regret that it can't
provide on other platforms....But, I tried it.
http://winpg.jp/~saito/pg_work/OSSP_win32/try-uuidwin32/
If someone wishes, I think that this is the place where pgfoundry is suitable.

Therefore, I will work an effort to clear the bug of uuid-ossp persistently.
Please give me time to a slight degree.

I appreciate your perseverance. thanks!

Hiroshi Saito

Hi

I just tried it, slightly better but not a runner....

Here is a sample of the results I get when running my test script, note
result vary but lack of duplicates does not.

Why do you not use the CreateUUID function in windows??

Regards

Eric

the uuid functions do not return unique values if used sequntially, or

i

believe without too much tme in between invocations.

the following test functions returns the same value!

returns varchar as

Re: BUG #4274: uuid returns duplicate values

Hi.

This can obtain a comfortable result.
http://winpg.jp/~saito/pg_work/OSSP_win32/pg8.3.3-win-bin-uuid-ossp-20080706.zip

I will adjust with Rarf-san.
Thanks!

Hi.

uuid of MS is the approach different from ossp. Then, I regret that it can't provide on
other platforms....But, I tried it.
http://winpg.jp/~saito/pg_work/OSSP_win32/try-uuidwin32/
If someone wishes, I think that this is the place where pgfoundry is suitable.
Therefore, I will work an effort to clear the bug of uuid-ossp persistently. Please give
me time to a slight degree.
I appreciate your perseverance. thanks!

Hiroshi Saito

Hi.

Sorry, late reaction....Now, private time has only a few.
Umm, It seems that the bug is probably contained in another part. I will investigate at
a weekend again.

Anyway, thank you for useful information.!

Hi

I would suspect that the clock used may not be precise enough

Not with standing, why not use the windows CreateUUID??

Slower system seems to fare better... (please see results below)

Hi

I just tried it, slightly better but not a runner....

Here is a sample of the results I get when running my test script, note
result vary but lack of duplicates does not.

Why do you not use the CreateUUID function in windows??

Regards

Eric

There is nothing, uuid-ossp has an official release place. It will evolve uniquely.
Ralf-san supplies a great module to us.!:-)
As for try-uuidwin32 (native-uuid of winapi), it is not suitable to contrib.
However, It may be pgfoundry supposing it is desired.

Re: BUG #4274: uuid returns duplicate values

Testing on my home system, looking good... will try on my office system Monday.

Note:
I am assuming that the uuid will mostly be used as a primary key on records that will exist in replicated databases to guarantee uniqueness. The problem that is see with the current uuid functions for this purpose is that the generated uuid is very random causing great performance issues with the index; at least when using oracle and ms sql server, did not try with postgres, but must be similar. Usually inserting random data into an index of any kind is a worst case stress test. Hence the older style of uuid, based on mac addresses and time tend to generate more sequential uuid's, at least when inserting a bunch of records at once.

In other words it would be nice to have the old fashioned style of uuid's.

Eric

Note that in the days of virtual machines, those more or less "invent"
their MACs. Since they just have to be unique in the subnet (or
"broadcast domain"), collisions on a more global scale will go
unnoticed. But they might bite you in a replicated database scenario.

I wouldn't trust "old fashioned uuids" anymore.

Re: BUG #4274: uuid returns duplicate values

I wouldn't trust "old fashioned uuids" anymore.

BTW: Windows has an integrated GUID creator. Used for a lot of things.
Used in all windows installations. THAT one should be fairly robust,
shouldn't it?

Would it be possible to have something like

ifdef win32
guid=windows-system-call-to-createguid()
