File creation can take a long time

Occasionally I use text_editor to take notes on my 5G 30GB iPod. This 
has always worked well in the past with the stock MK3008GAL hard drive. 
(BTW I recommend opti2.kbd 
http://www.rockbox.org/wiki/LoadableKeyboardLayouts ) Recently I 
upgraded to a HS12YHA, which is 120GB with 4k sectors.

I was playing WMA. When I saved in text_editor, creating a new file, it 
seemed to hang. The wait was long enough that I reset the iPod, leaving 
a 0 length file. Then I tried again, also playing WMA and waiting longer 
and it worked. This made me think that Rockbox took a long time to look 
through the FAT because the drive was mostly full and free space was 
toward the end.

Specific conditions are needed to reproduce this. FAT32 has an fsinfo 
sector with a hint value telling where the first free cluster should be 
located. Rockbox makes use of this, allowing fast cluster allocation. 
After mounting the iPod in Windows, the free space hint was 0x1da2. Then 
I played that same WMA album, and reproduced the problem. The free space 
hint was now 0x321da2, showing that Rockbox must have scanned though 
many clusters in the FAT. Here is sudo dd if=/dev/sdb2 bs=512 count=1 
skip=1 | hexdump -C

OpenID 2 end of life....

Hi,

I was about to register to gerrit so I could add some of my patches to
rockbox and came across this note from google about the end of support
for OpenID 2.0 on the 20th of April.

https://support.google.com/accounts/answer/6135882

Is there a plan in place for move to OAuth?

Regards...

...Mike

"User selectable freq scaling governor"

Hi,

A setting for user selectable freq scaling governor (for ibasso players)
was added in 040306a. Can anyone explain why this is needed? It's a
setting that the vast majority of users will have no clue about, while
those who actually know what it means won't know what to set it to.

I would expect that for rockbox use, one of those possible governors
will consistently be the best one to use. I'd suggest figuring out which
one that is and then using it. For developer experiments, a debug menu
item is a good way to play with this, but a user-visible setting?
Really?

Frank

commit 9076b433

The below commit isn't necessary.

buflib buffers can be passed to yielding functions just fine. Problems 
only arise if the are concurrent allocations, for example if two threads 
allocate from the same context simultaneously or if the callee does it's 
own allocations. This can't happen in the pictureflow case, it has it's 
own context and a single thread allocating from it.

Therefore the problem isn't yield() itself, but possible concurrent 
buflib_alloc() calls that result from the thread switch. This is because 
compaction only ever happens on allocation (and not in a backgroud 
thread or so).

Best regards.

     PictureFlow: Add move callback for buflib allocations

     If we don't provide a callback to buflib_alloc(),
     the buffer is always movable (to reduce fragmentation).

     Since we pass our buffer to functions that call yield(),
     this could lead to memory corruption on buflib compaction.

d81b362: iBasso DX50: Digital filter roll off setting.

This commit should not have been made without discussion because:

1)  We had previously rejected it
2)  We generally try to avoid giving users frivolous hardware settings.

buildserver/buildclient and iBasso DX50/DX90: Major code cleanup and reorganization.

Hello.

As stated here http://gerrit.rockbox.org/r/#/c/1043/ i will submit this 
patchset in a few days.

This will most likely break the current build for ibassodx50.

1.

If http://git.rockbox.org/?p=www.git;a=blob;f=buildserver/builds;hb=HEAD 
is the current configuration of the build server, than this
line

android19:0:ibassodx50:iBasso DX50:rockbox.apk:110450:../tools/configure 
--target=ibassodx50 --type=n && make apk

shoud probably be

android19:0:ibassodx50:iBasso DX50:rockbox.zip:110450:../tools/configure 
--target=ibassodx50 --type=n && make zip

as this is no longer a PLATFORM_ANDROID device (no JAVA parts).

Adding ibassodx90 would be nice.

2.

The Android specific configuration has changed:

recorder build

Hi,

The recorder build is still failing due to size limits, and it's
unlikely to get better soon. I'm proposing to remove it from the
automated build system.

It's close enough to the recorderv2 to avoid breakages slipping
through, and having that persistent red makes reds elsewhere less
noticeable.

Any objections?

Frank

Completed extended metronome plugin (gerrit #887)

Hi,

after a few prototypes I have pushed my (first) final version of an
extended metronome plugin to Gerrit:

	http://gerrit.rockbox.org/r/#/c/887/

Testing and eventually merging of that into rockbox proper would be
welcome. This replaces the existing metronome plugin now, as all the
functionality is there.

PS: Gerrit items 1100 to 1116 are junk caused by me not squashing
commits before pushing ... they can be ignored and I would abandon them
if I could remember where my OpenID thingy for Gerrit came from.

Revert "Rewrite filesystem code (WIP)"

[Duplicating [3] in mailing list for wider audience and discussion.]

Commit 7d1a47cf ("Rewrite filesystem code (WIP)") introduced
regressions ([1],[2]) on several rk27xx targets, making them nearly unusable.

Due to size of this change it's nearly impossible to find the root
of the problem, so I'm suggesting to revert it for now.

I'll keep searching the source of problem. It definitely will take a
lot of time. But once I'll find it we could revert the revert back.

We don't have stable release for this targets, cause they are never
been officially stable. So dev builds is the only option for users and
I would like to not keep them broken yet another hell knows how many
month.
