I don't see the corresponding delete to this creation?

[ahendrickson, 2011/05/19 20:16:49]

That's odd.

On my machine, it detected that DownloadCreateInfo.* was renamed to
DownloadHistoryInfo.*.

I don't know why that didn't appear on the CL.

I may have to fix it by creating another CL that removes the originals, and
commit it after this one . . .

[Paweł Hajdan Jr., 2011/05/19 16:18:25]

Is it really primarily used for querying the history service? That comment seems
confusing.

[ahendrickson, 2011/05/19 20:16:49]

Fixed.

Is this file moved from chrome/browser/history? I don't see any
chrome/browser/history/download_create_info.h deletions in this CL.

[ahendrickson, 2011/05/19 20:16:49]

Yes it is.

I'm not sure how to fix the CL, as it is correct on my machine.

[Paweł Hajdan Jr., 2011/05/20 09:04:42]

I see, I suspected that kind of problem. Should be fine when committing, just
please make sure the old files really got deleted in svn.

Let's describe the history service parts in HistoryService, especially the info
what the history service uses. That part of the comment is very likely to get
out of sync with the code.

[ahendrickson, 2011/05/19 20:16:49]

Done.

Instead of saying DownloadItem fields, please make sure each member has a brief
description. Especially "int32 state" is a bit surprising.
