SERVER-14835 fix fassert 16143 on PPC64 LE systems in LogFile::synchronousAppend()

[corentinbaron]

Having mongoDB using the system page size requires quite some work, yet it works fine on PPC 64 with a 64kB page size (which is the case on Ubuntu 14.04 Little Endian).

Hi Corentin,

Thanks for signing the contributor's agreement. I can't seem to find a SERVER ticket in our JIRA queue for this pull request. Could you please create one here?

https://jira.mongodb.org/browse/SERVER

here it is: https://jira.mongodb.org/browse/SERVER-14835

Also, we'd like to have this also on 2.6, should I submit a pull request on the 2.6.4-rc0 branch?

Hi Corentin,

Pull requests are handled by setting the Backport field in the SERVER ticket to Requested. If the SERVER ticket is resolved and the Backport is approved, we will cherry-pick the commit to the upcoming 2.6 branch.

Hi @corentinbaron,

Have you read @andy10gen and @kangas's comments on the SERVER-14835 ticket?

I don't think we can merge this pull request in its current form because the right thing to do would be to fix the expression in the fassert() itself, not disable it.

Please let us know if you are interested in updating your patch based on the recommendations in the SERVER ticket.

Regards,
Ben

hello, i know that this is not related to this post but help me......
i have a requirement where i have make the document names dynamic means for eg: my document name is company_address in company collection and iam assigning this document name to a variable and using it in where condition but its not working...
...
var address="company_address";
db.company.find({address:"USA"})
...
Can any one help me to fix this problem.....

@Gayatri31, the best place to get answers about how to use MongoDB is the mongodb-user Google Group

Your question is a matter of Javascript syntax. Try this instead:

// Build query document. Cannot use object literal syntax for variable keys.
var toFind = {};
toFind["company_address"] = "USA";

// Use query document
db.company.find(toFind);
