Can you provide the recovery.fstab for a device using ubifs?

I can't really review this properly without seeing what that file looks like.

Hi Dave, now only Dolphin use nand flash with ubifs. Its fstab is attached. Thanks!

I think it's different to bug 1007570.

Comment 7

[Gabriele Svelto [:gsvelto]]

I think you will need bug 1007570 because attachment 8422147 [details] looks like a Linux fstab file.

Comment 8

[Dave Hylands [:dhylands]]

My take on this is that bug 1007570 should solve the problem that this bug is trying to solve, but IMHO it does it in a cleaner fashion.

Comment 9

[Kai-Zhen Li [:seinlin][:kli]]

Dave and Gabriele, Thanks! But we still need to have ubifs for B2G_FOTA_FSTYPE. I will update the PR based on bug 1007570 and have ubifs supported.

Lianxiang, 

Per our offline discussion,  
Using 'device/sprd/scx15/nand/fstab.scx15' will casue error in recovery ROM.
Need to use 'device/sprd/scx15/nand/recovery.fstab' for dolphin.
But the current format of recovery.fstab may cause an error in build fota update.mar.

Can you help to update 'device/sprd/scx15/nand/recovery.fstab' in this format?

On our device, we use ubifs, I can not find any "../by-name/system" in /dev folder.
why not change the Android.mk file to parse the 'device/sprd/scx15/nand/recovery.fstab'?

Comment 19

[Kai-Zhen Li [:seinlin][:kli]]

Attachment: recovery.fstab

For dolphin, it needs to use the attached recovery.fstab in order to make the recovery ROM work properly. This file looks like a linux fstab, but it can be recognized by makefile.

Dave, do you think it is reasonable to do one more check for the fstab in comment 19?

Probably, I think we could also simply this check as below.

   $(if $(FSTAB_FILE),
     $(eval STARTS_WITH_DEV := $(shell grep '^/dev/' $(1) | grep '/system'))
-    $(if $(filter /system, $(STARTS_WITH_DEV)),
+    $(eval STARTS_WITH_NAME := $(shell grep -v '^\#' $(1) | grep -v '^/' | grep '/system'))
+    $(if $(filter /system, $(STARTS_WITH_DEV) $(STARTS_WITH_NAME)),
       $(eval FSTAB_TYPE := linux))

Do more check in Makefile

Review of attachment 8428563 [details] [diff] [review]:
-----------------------------------------------------------------

So why are you storing this into a variable called STARTS_WITH_DEV ?

None of the lines that you're matching start with dev.

I think that we really need examples in the comments of the various style of fstab that are being parsed here.

We seem to have 3 variants:

1 - style that starts with /dev:

/dev/block/platform/msm_sdcc.1/by-name/system /system ext4 ro,barrier=1 wait

2 - android style?:

/system	yaffs2	system

3 - This new style:

system /system	ubifs defaults defaults

Interestingly, all 3 styles share the attribute that the file system comes in the word after the word with /system (as a standalone word) in it.

Comment 23

[Kai-Zhen Li [:seinlin][:kli]]

Yes we need to handle 3 styles. 
attachment 8428563 [details] [diff] [review] is my WIP, just to verify if my idea does work. STARTS_WITH_DEV is used only one time, that's why I try to reuse it. 
But this is confused, so I got another solution in comment 21. 
Finally, I think the code could be as below where style 1 and 3 will be recognized as linux format.

---
   $(if $(FSTAB_FILE),
     $(eval STARTS_WITH_DEV := $(shell grep '^/dev/' $(1) | grep '/system'))
     $(eval STARTS_WITH_NAME := $(shell grep -v '^\#' $(1) | grep -v '^/' | grep '/system'))
     $(if $(filter /system, $(STARTS_WITH_DEV) $(STARTS_WITH_NAME)),
       $(eval FSTAB_TYPE := linux))
---

Dave, do you think this is reasonable?

Comment 24

[Dave Hylands [:dhylands]]

That looks better :)

I'd still like to see a comment with the 3 different styles go into Android.mk

[James Zhang (Spreadtrum)]

Reopen.
As talked in email, we should add tools/update-tools/bin/gonk/update-binary ubifs support.

Comment 29

[Kai-Zhen Li [:seinlin][:kli]]

Dave, 

Now update.mar for dolphin can be built but failed to update and the root cause is update-binary can't mount ubifs partition.

I think there could be 2 possible solutions,

1. Update tools/update-tools/bin/gonk/update-binary to the one which can support ubifs.

2. Able to define the update-binary used for update.zip in build time. 
   Such as, when a device exports a path of update-binary, tools/update-tools/update_tools.py will use if for update.zip.

Do you think which solution is more reasonable?

Comment 30

[Jason Smith [:jsmith]]

Not a vendor bug. This is a gonk bug.

So where is the source for the update-binary?

If the source is in a repo that we control, then I think that 1 makes sense. If the source is not in a repo that we control then I think that 2 is probably more appropriate. Although I tend to favor using command line arguments over environment variables, unless the environment variable is already part of the build.

I think that the calculated path for the prebuilt update-binary is wrong.

If I'm wrong, then r+, but otherwise I think that this change would break existing usage.

I verified when --update-bin is not specified, the pre-built one will be used, 'tools/update-tools/bin/gonk/update-binary'. So this won't break existing usage.

PR is updated, I verified it does work properly with/without TARGET_UPDATE_BINARY.

James, this is an example how device specify update-binary for update.zip. Please do not land this patch as I didn't test it. The name of the binary file is not limited to 'update-binary'. Could you help to add one for dolphin? Thanks!

But how to build the update-binary?
Can you give us the origin source code? Lianxiang said this binray which is built on my side can't work fine.

The original source is
https://android.googlesource.com/platform/bootable/recovery.git

In dolphin, The source code is under "bootable/recovery/updater" and it can be built by.
$ ./build.sh updater
