ubuntu svn server install ( over apache )

I installed svn server under ubuntu LTS 10.04 64 bits

SVN Server Setup

1. install essentail packages

#  sudo apt-get install subversion libapache2-svn apache2

2. create repository

 # svnadmin create /home3/swmgr/tmpsvn/sample

3. configure conf file

open  /home3/swmgr/tmpsvn/sample/conf/svnserve.conf

then uncommnet belows
 auth-access = write ==> set permission
 password-db = passwd ==> indicate passward file

open /home3/swmgr/tmpsvn/sample/conf/passwd

then add user and passward

[users]

user = passwd
dokyun = hellscream

4. start svn server
 svnserve -d -r /home3/swmgr/tmpsvn/sample

5. check
# svn checkout svn://192.168.0.4 ./svn
 or
# svn checkout svn://localhost ./svn

if  ,,, /db/txn-current-lock': Permission denied  error happens when svn access
check the directory permission.
$ chmod -R 775 /home3/swmgr/tmpsvn/sample

SVN over Apache

1. set directory owner
 # sudo chown -R www-data /home3/swmgr/tmpsvn/sample/

2. configure
 open /etc/apache2/mods-enabled/dav_svn.conf
 then add

<Location /svn>
  DAV svn
  SVNPath /home3/swmgr/tmpsvn/sample
  AuthType Basic
  AuthName "Subversion Repository"

  AuthUserFile /etc/apache2/dav_svn.passwd

  Require valid-user
</Location>

3. add user
# sudo htpasswd2 -cm /etc/apache2/dav_svn.passwd dokyun
 or
# sudo htpasswd -cm /etc/apache2/dav_svn.passwd dokyun

4. restart apache
 sudo /etc/init.d/apache2 restart
5. check

 refer to http://davidwinter.me/articles/2006/02/16/subversion-over-apache-2-on-ubuntu/

sulogin: no password entry for root

default console device is not set properly in inittab
Set tty device in inittab , for example

if console was set as

::respawn:/sbin/getty 115200 ttyO0

in inittab and you started with ttyO2,  then

sulogin: no password entry for root

message shows

set

::respawn:/sbin/getty 115200 ttyO2

you can log in properly

Building Android system

Move to android root directory.

Set up buildenv as below

dokyun@android$
dokyun@android$ source ./build/envsetup.sh
including device/samsung/maguro/vendorsetup.sh
including device/samsung/tuna/vendorsetup.sh
including device/ti/panda/vendorsetup.sh
including sdk/bash_completion/adb.bash
dokyun@android$

Set up build target as below
$ lunch [Build-name]-[build type]

build name is target device name such as panda or maguro
build type is build configuration such as debugging option or limitation.

currently I do not have special target , select emulator for build-name , eng for build-type

dokyun@android$ lunch full-eng
============================================
PLATFORM_VERSION_CODENAME=REL
PLATFORM_VERSION=4.0.1
TARGET_PRODUCT=full
TARGET_BUILD_VARIANT=eng
TARGET_BUILD_TYPE=release
TARGET_BUILD_APPS=
TARGET_ARCH=arm
TARGET_ARCH_VARIANT=armv7-a
HOST_ARCH=x86
HOST_OS=linux
HOST_BUILD_TYPE=release
BUILD_ID=ITL41D
============================================
dokyun@android$

then build

dokyun@android$ make -j4

It can takes more than 1 hour at first build , it depends on your build system

You can also select manually the target board as like below

dokyun@android$ lunch
You're building on Linux
Lunch menu... pick a combo:
     1. full-eng
     2. full_x86-eng
     3. vbox_x86-eng
     4. full_maguro-userdebug
     5. full_tuna-userdebug
     6. full_panda-eng
Which would you like? [full-eng] 6
============================================
PLATFORM_VERSION_CODENAME=REL
PLATFORM_VERSION=4.0.1
TARGET_PRODUCT=full_panda
TARGET_BUILD_VARIANT=eng
TARGET_BUILD_TYPE=release
TARGET_BUILD_APPS=
TARGET_ARCH=arm
TARGET_ARCH_VARIANT=armv7-a-neon
HOST_ARCH=x86
HOST_OS=linux
HOST_BUILD_TYPE=release
BUILD_ID=ITL41D
============================================
dokyun@android$ make -j4

• Installing repo

Repo is a tool that makes it easier to work with Git in the context of Android.

$ mkdir ~/bin
$ PATH=~/bin:$PATH

$ curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo
$ chmod a+x ~/bin/repo

As you can see , it just get repository related script form https://dl-ssl.google.com/dl/googlesource/git-repo/repo and make excutable

• Initializing a Repo client

First make working directory, in my case

$ mkdir ~/android
$ cd ~/android

then initialize repository.

$ repo init -u https://android.googlesource.com/platform/manifest

It shows below error at first time

-----------------------------------------------------------------------
*** Please tell me who you are.
Run
  git config --global user.email "you@example.com"
  git config --global user.name "Your Name"
to set your account's default identity.
Omit --global to set the identity only in this repository.
fatal: empty ident  <dokyun@redbomb-server.(none)> not allowed-----------------------------------------------------------------------

as you can see on the error message, type your email and name

$ git config --global user.email "dokyun.beon@gmail.com"
$ git config --global user.name "dokyun beon"

then excute again
$ repo init -u https://android.googlesource.com/platform/manifest
$ repo init -u https://android.googlesource.com/platform/manifest -b android-4.0.1_r1
$ repo sync

as you can see, down load is done

simple usage of devmem

• Introduction

/dev/mem represents the phyical memory.
devmem uses /dev/mem and gives convenience for accessing memory io directly on console

Download devmem2.c from anywhere then cross-compile

arm-none-linux-gnueabi-gcc -c devmem2.c -o devmem

• usage

./devmem [ADDRESS]
./devmem [ADDRESS] w [VALUE]

zlib cross compile

• official home

 http://zlib.net/

• download

http://zlib.net/
or
http://sourceforge.net/projects/libpng/files/zlib/1.2.7/zlib-1.2.7.tar.gz/download

•   build and install ( cross compile )

configure command does not include CC configuration.
You must put CC and others directly

$ CC=arm-none-linux-gnueabi-gcc AR=arm-none-linux-gnueabi-ar RANLIB=arm-none-linux-gnueabi-ranlib ./configure --shared --prefix=$PWD/build

make
make install

how to run codesourcery on x86 64bit linux system

In ubuntu 10.04 or higher

$ sudo apt-get install ia32-libs

other cases refer to official pages

LZO build and install

• Introduction

LZO is a data compression library which is suitable for data de-/compression in real-time. This means it favours speed over compression ratio.
LZO is written in ANSI C. Both the source code and the compressed data format are designed to be portable across platforms.
LZO is lossless compression algorithm
LZO is using in ubifs

• official home

http://www.oberhumer.com/

• download

http://www.oberhumer.com/opensource/lzo/

• build and install ( cross compile )

./configure --host=arm-none-linux-gnueabi --prefix=/targetnfs/usr
make
make install

sometimes you need to contain this lib in toolchain

./configure --host=arm-none-linux-gnueabi --prefix=/opt/toolchains/arm-2009q1/usr/
make
make install

mtd-utils build and install

• officail homepage

http://www.linux-mtd.infradead.org/index.html

• download

ftp://ftp.infradead.org/pub/mtd-utils/
or
git clone git://git.infradead.org/mtd-utils.git mtd-utils

• configure and build for cross compile

mtd-utils does not supprot configure.
You must modify Makefile of commom.mk directlry

In common.mk defines CC

CC := $(CROSS)gcc
AR := $(CROSS)ar
RANLIB := $(CROSS)ranlib

just add variable CROSS on top of common.mk for example

CROSS :=arm-none-linux-gnueabi-

• Install

In Makefile instill DIR defined as DESTDIR

install:: $(addprefix $(BUILDDIR)/,${BINS}) ${SCRIPTS}
        mkdir -p ${DESTDIR}/${SBINDIR}
        install -m 0755 $^ ${DESTDIR}/${SBINDIR}/
        mkdir -p ${DESTDIR}/${MANDIR}/man1
        install -m 0644 mkfs.jffs2.1 ${DESTDIR}/${MANDIR}/man1/
        -gzip -9f ${DESTDIR}/${MANDIR}/man1/*.1

Do below commnad

$ make install  DESTDIR=/home/user/mtd/install

finally you can do as below

$ make CROSS=arm-none-linux-gnueabi- DESTDIR=/home/user/mtd/install all install

• build error handling

sometimes it can return errors, because of cross compiler restriction

$ error: sys/acl.h: No such file or directory

It means your cross toolchanin does not support ACL.
mtd-util has build option for this

$ make CROSS=arm-none-linux-gnueabi- WITHOUT_XATTR=1

The access control list(ACL) enables higher flexible access control based on UNIX users and groups than traditional user/group/others model. '--with-xattr' or '--with-posix-acl' options on mkfs.jffs2 enables to
copy the ACLs associated with any files in host environment into jffs2 image file. The purpose of this feature is improvement of security in embedded region.

refer to http://lists.infradead.org/pipermail/linux-mtd/2006-November/016814.html

error: lzo/lzo1x.h: No such file or directory

There is an option build without LZO
But it does not works properly, also LZO must be needed because ubifs includes LZO

$make CROSS=arm-none-linux-gnueabi- WITHOUT_XATTR=1 WITHOUT_LZO=1

It will cause build error also in ubifs related package
Refer to http://dokyunblog.blogspot.kr/2012/07/introduction-lzo-is-data-compression.html
Contain LZO lib in toolchain.

DMA related kernel APIs

dma_map_single
  ==> map DMA address for virtual memory,
  ==>use kmalloc if continuous memory is not enough, it returens fail
dma_unmap_single
  ==> free memory by allocating dma_map_single
dma_alloc_cohernet
  ==> allocate coherent memory for DMA
  ==> it allocates memory in conherent area,
  ==> refer to memory.h in architecture
  ==> it can be decided by CONSISTENT_DMA_SIZE

other APIs
  ==> dma_pool_create
  ==> dma_pool_alloc
  ==> dma_pool_free
  ==> dma_pool_destory
  ==> dma_alloc_writecombine

Also you can decide dma memory attributes by using kernel APIs

For more detail,  refer to dma-api.txt in kernel doc

condiserations when you alloc DMA memory

1. allocate meory in coherent area ?
2. use memory as like pool?
3. how mush you are using coherent memory
4. swap area is used or not

But everytime you can not have enough memory......if you have, it's not real
