[alsa-devel] [GIT PULL] Extra ASoC updates for v4.16
This pull request is for things that arrived in the last week of the v4.15 cycle, I'm sending it directly since Takashi still seems to be on holiday (I'd thought he'd be back this week). There's some random new development in here and also a bunch of bugfixes.
The I/O fix mentioned in the tag below is pretty important and would be especially good to have fixed in -rc1, it was reported right at the end of the v4.15 cycle so didn't make Takashi's early pull request and causes a power regression on some of the OMAP platforms. If this request is a problem I can do a smaller one with just that in it.
Unfortunately I can't figure out how to generate a sensible git pull request for this since it ended up containing both v4.15-rc9 and my prior pull requests. When I use your tree as the reference git pull goes with your -rc9 tag so the diffstat contains way more stuff than you'll actually get but that seems to be the best alternative.
The following changes since commit 0c5b9b5d9adbad4b60491f9ba0d2af38904bb4b9:

---------------------------------------------------------------- ASoC: Updates for v4.16
With the merge window having been delayed for another week here's another batch of updates that came in during that week. There's a few important fixes in here, mainly a fix for I/O on a number of devices caused by some of the component rework and a fix for a potential issue if more than one component in a link provides compressed operations.

No. I'm not taking this completely crazy stuff.
It has 54 commits total. Of those, 35 are merges. Many of those merges are complicated octopus merges that don't bring in _anything_ new, because the commits they merge all came in through some other source.
Really. Ask yourself - why would I take that kind of complete and utter mess, where two thirds of the commits don't actually do anything but mess up the history and make things hard to follow?
Unfortunately I can't figure out how to generate a sensible git pull request for this since it ended up containing both v4.15-rc9 and my prior pull requests.
git pull-request doesn't necessarily work if you have complex history, and this is more complex than most, by a long shot.
In fact, it was so complex that just "git merge" - which usually completes in under a second - spent a lot of CPU time on that merge from hell. It probably had a ton of different common merge points that all ended up being recursively merged together to get a base for the final merge.
[ Whee. I went back and looked. There's 88 merge-bases. EIGHTY-EIGHT! Christ. That must be some kind of record. Poor git. It did end up with a clean merge in the end, but no wonder it took tens of seconds to do so ]
It is expected that anybody who doesn't have a linear history knows how to do a test merge and report the result that way.
That said, history really generally isn't expected to be this messy _anyway_. This looks like some drug-induced frenzy of "let's just merge random branches for no good reason even if they have been merged earlier".
So pulled and then unpulled in horror.
Because some of those merges look very Lovecraftian, with the whole gigantic octopus merge theme. Cthulhu and tentacles galore.

Sorry for that, I'm having a really bad net connection at our hotel, so I cannot respond each mail and work on my git tree...
There's some random new development in here and also a bunch of bugfixes.
No. I'm not taking this completely crazy stuff.
It has 54 commits total. Of those, 35 are merges. Many of those merges are complicated octopus merges that don't bring in _anything_ new, because the commits they merge all came in through some other source.
Really. Ask yourself - why would I take that kind of complete and utter mess, where two thirds of the commits don't actually do anything but mess up the history and make things hard to follow?
Mark has been always a torturer for git merge, so it's not new :) I used to have multiple topic branches in the past, so I have understanding of his management style. A topic branch per vendor is sometimes nicer to make the changes isolated from others. Though, I agree that the case like this is too much, too. Maybe at most a few (3-5) topic branches?
Unfortunately I can't figure out how to generate a sensible git pull request for this since it ended up containing both v4.15-rc9 and my prior pull requests.
git pull-request doesn't necessarily work if you have complex history, and this is more complex than most, by a long shot.

So, would you suggest to straighten commits by rebase at this time? The rebase was a thing to be avoided in general, and that's the reason of the messy multiple merges.
In anyway, Mark, please send a renewed pull request to Linus directly for this fix, as I'll still be less responsive until the next weekend.
thanks,
Takashi

You don't need to rebase the commits themselves - not the ones that are real commits that do things.
But the merging up of the commits is insane.
For example, these merges bring in basically *nothing* new (ok, so some of them bring in a couple of commits, but see the pattern here?):
- 3df40aaee07cd24df42ace7fa88fb4db32ad9a30 merge of a remote tracking branch that had already been merged

...
then I got really tired of walking through things.
See a pattern above? It's not that the actual commits that change something need to be rebased.
It's the *MERGES* that need to be stopped. I don't know what the hell Mark is doing. There's some kind of completely mindless and crazy merging going on.
And I think it's entirely automated *GARBAGE*. Look at this:
git log --pretty='%cn %cd' --merges 3f551e3cefcf..e0a663f24d53
which shows just the committer and the commit date of the merges in question. And there is a total of 35 merges in that range, but what's notable is that ALL BUT ONE of them happen in between
Fri Jan 26 15:24:49 2018
and
Fri Jan 26 15:27:56 2018
so we had 34 mindless merges in just over three minutes. That's a merge every six seconds.
Put another way: Mark is doing some automated stupid crap. The result of that stupid crap is all those merges of stuff that had already been merged.
It's wrong, and I'm not pulling that kind of idiotic auto-generated merge hell.
But there are actually real commits in there, as shown by
git log --oneline --no-merges 3f551e3cefcf..e0a663f24d53
but those 19 real commits are basically overwhelmed by the 34 crazy automated and complex merges.
And I really don't think they need to be rebased. They just need to be merged *sanely* instead of being merged mindlessly with octopus merges where one branch (out of five) _might_ have had a new commit.
See what I'm complaining about?

Right, it's basically a couple of octopus merges split up into chunks of 5 branches because you didn't like the octopus merges and also said you don't like ongoing development branches with no or few non-merge commits. I'm keeping everything on topic branches (mainly per device) because we get problems with people discovering that they need branches in other trees and the entire tree gets too big to merge elsewhere. It's also occasionally it's useful to be able to just throw away a branch if it turns out to have been a bad idea.
For example, these merges bring in basically *nothing* new (ok, so some of them bring in a couple of commits, but see the pattern here?):

Indeed, it's 100% automated. The script just goes through and merges all the branches it sees and relies on git to elide empty merges which happen, having first merged in any older tags to avoid duplication of in flight merges.
I'm frankly a little bit confused about what went wrong here, usually git does manage to elide empty merges - for example, if I ask git to merge four branches two of which are already merged:
$ git merge asoc/fix/compress asoc/fix/core asoc/fix/mtk asoc/fix/stm
it gives me "Merge: 7614447873f9 06190937b9de 748bce8e6c7e" (ie, two of four branches merged) which looks a lot neater. This time something caused git to miss some of the merges, I expect it's the amount that happened since my original tag due to the combination of that being a bit early for Takashi's vacation and then the merge window being delayed by several weeks meaning that things were too far back in history. I can't actually see anything in the manual page on this behaviour.
Anyway, here's a redone pull request. The diffstat still has far too much stuff in it for reasons I can't quite figure out, AFAICT it's that some of the fix branches are based on earlier pull requests but I don't want to get myself in a mess trying to rebase to confirm. There's 8 merges here, two are from the development history (the twl fix was a single patch to two branches and some of the compress development needed the corresponding fixes branch). The remaining 6 are an attempt to balance not having large octopus merges with not having huge numbers of single merge commits. Hopefully this is OK for you, if not let me know what you're looking for.

---------------------------------------------------------------- ASoC: Updates for v4.16
With the merge window having been delayed for another week here's another batch of updates that came in during that week. There's a few important fixes in here, mainly a fix for I/O on a number of devices caused by some of the component rework and a fix for a potential issue if more than one component in a link provides compressed operations. The I/O fixes are particularly important as the problem causes a power regression on a number of OMAP platforms.

I'm frankly a little bit confused about what went wrong here, usually git does manage to elide empty merges - for example, if I ask git to merge four branches two of which are already merged:
Yes, so git does elide truly trivial merges, but the git triviality test is actually not "have all the commits been merged elsewhere", but "are all the branches completely just subsets in history of each other".
So a single extra merge commit that exists in one branch but not the others will defeat that, and then you get a merge of a merge etc. That's something we saw early on, when people would do daily back-merges - even if there was no extra work in the development branch, the previous back-merge *itself* would mean that the merge wouldn't fast-forward to the upstream code, but would just do another merge, because upstream wasn't a full superset of the development branch due to the previous back-merge that wasn't upstream.
But in this case, the issue doesn't seem to be a previous back-merge, but simply that the commits ion question had been merged up-stream - but they weren't in your development branch, so when your development branch does a merge, to *that* branch it looks like new commits, even if it isn't anythign new or interesting to *me*, because I got those commits from Takashi's pull two weeks ago.
This new pull request looks better, I'll look at it next.

Ok, pulled and pushed out.
And the reason your diffstat looked like crap is that "git request-pull" simply does a diff between two points, not a real merge. That diff works fine for straight-line development, or for simple history, but when you have multiple branches that came in at different points, there is no single starting point for the diff.
So git picks _one_ common point for the start of the diff, and that is the right thing for the simple cases, but for the case where you have lots of different starting points, that one point will be right for _one_ branch, but for another branch it will contain (or miss) a lot of other development that happened between the starting points of the different branches.
But since "diff" is fundamentally a comparison between two points in history, it very fundamentally cannot do better.
If you want to get the real diffstat for that case, you have to do an actual test merge. A merge will do a *much* more complex operation, taking *all* the different base points into account. It really is a lot more complex thing. Then you can diff the two points of "before merge" and "after merge".
