How to create local and remote ssh git repo in Mac OS X

(1) Install git for Mac OS X

mkdir ~/src
cd ~/src/
curl -O http://kernel.org/pub/software/scm/git/git-1.6.5.3.tar.bz2
tar -xjvf git-1.6.5.3.tar.bz2
cd git-1.6.5.3
./configure --prefix=/usr/local
make
sudo make install
git --version

(2) Create localrepo in local harddisk / SMB Share (assume already init as a repository)
init as a git repository

cd ~/myproject
git init
git add .
git rm -r --cache build     # ignore the build directory for iPhone project
git commit -m 'Initial commit'

git mkdir -p ~/git
git clone --bare ~/myproject ~/git/myproject.git
touch ~/git/myproject.git/git-daemon-export-ok

git mkdir -p /Volumes/Data/GIT
git clone --bare ~/myproject /Volumes/Data/GIT/myproject.git
touch /Volumes/Data/GIT/myproject.git/git-daemon-export-ok

push to localrepo

cd ~/myproject
git remote add localrepo ~/git/myproject.git
git push localrepo master
git log

(3) Suppose you have a project in ~/myproject
and the remote ssh server login is user@xxx.xxx.xxx.xxx
both client and server have git installed

(4) Create sshrepo in remote server over ssh

ssh user@xxx.xxx.xxx.xxx "mkdir -p /Volumes/HD/git/myproject.git; cd /Volumes/HD/git/myproject.git; git --bare init; touch git-daemon-export-ok"

check the location of remote git binary and the remote ssh login shell


ssh user@xxx.xxx.xxx.xxx "which git-upload-pack"
ssh user@xxx.xxx.xxx.xxx "echo \$PATH"

mine is /usr/local/bin/git-upload-pack


if the remote login shell does not include path of git, create ~/.bashrc in your remote ssh login shell


ssh user@xxx.xxx.xxx.xxx "echo 'export PATH=\${PATH}:/usr/local/bin' > ~/.bashrc"

push to sshrepo

cd ~/myproject
git remote add sshrepo ssh://user@xxx.xxx.xxx.xxx/Volumes/HD/git/myproject.git
git push sshrepo master
git log


Test git clone

cd ~
git clone ~/git/myproject.git workinglocal
cd workinglocal
git log

or


cd ~
git clone ssh://user@xxx.xxx.xxx.xxx/Volumes/HD/git/myproject.git workingremote
cd workingremote
git log

How to Branch

git branch -r                 # show branch in repo
git checkout -b todo origin/to-do-branch # checkout a new branch
git checkout master           # checkout the master branch

git checkout localrepo/master # checkout the master branch in localrepo
git checkout sshrepo/master   # checkout the master branch in sshrepo

git branch next               # create new branch
git add .
git commit -m 'commit nextbranch'
git push localrepo next

git branch -b cygwin
git branch -r
git add *
git commit -m 'commit cygwin branch'
git push origin cygwin

How to checkout a previous commit

git log # show log of previous commit
git log --format=oneline # show log of previous commit log hex digit
git checkout 838fbf2e9b050d2350694235bbf5e9a11fa7acea # commit log hexdigit
git checkout 838fbf2e9b050d2350694235bbf5e9a11fa7acea -- file1/to/restore file2/to/restore # checkout files to restore

How to push to github

git config --global user.name "javacom"
git config --global user.email "javacomhk@yahoo.com"
git remote rm origin
git remote add origin git@github.com:javacom/toolchain4.git
git push origin master

How to compile mobilesubstrate extension in iPhone gcc for OS 3.0

(1) You need iphone gcc installed in your jailbroken iPhone / iPod Touch with firmware 3.0 or above

iPhone gcc is available in Cydia. To install it in you need to do these


# assume you have installed APT 0.6 Transitional and Aptitude and wget in Cydia, so that you can use the command apt-get
# if libgcc is broken in Cydia, you have to install it manually before iphone-gcc
wget http://apt.saurik.com/debs/libgcc_4.2-20080410-1-6_iphoneos-arm.deb
dpkg -i libgcc_4.2-20080410-1-6_iphoneos-arm.deb
# install iphone-gcc
apt-get install iphone-gcc


Moreover, you need these utilities as well


apt-get install make ldid zip unzip wget


for editor in iPhone you can use vim or nano

(2) You need the header files of toolchain and SDK 3.0, libsubstrate and classdump the SpringBoard and UIKit headers

The building of iPhone gcc in Linux and header files (updated for OS 3.0) is here in
http://www.saurik.com/id/4

The updated mobilesubtrate header files are here

The classdump procedure is here

But all these involved a lot of downloading and patching, so I put all the downloading/classdump/patching in one zipped tar file (sys30.tgz). You can download it (about 96M) here

(3) copy and untar the required headers and libraries (say copy to /var/mobile/sys30.tgz) and install it in iPhone / iPod Touch say

mkdir /var/toolchain/
cd /var/toolchain/
tar -xzvf /var/mobile/sys30.tgz


(4) Use this sample mobilesubstrate extension (ExampleHook.zip) and unzip it to test. You need to apt-get install mobilesubstrate in iPhone / iPod Touch first

http://apiexplorer.googlecode.com/files/ExampleHook.zip

apt-get install mobilesubstrate
wget http://apiexplorer.googlecode.com/files/ExampleHook.zip
unzip ExampleHook.zip
cd ExampleHook

make (to compile and codesign)
make install (to install), after install you need respring the device to test
make uninstall (to uninstall), after uninstall you need respring as well

respring utility is available from my cydia source http://cydia.iphone.org.hk/apt/

(5) You can also checkout a copy of the iphone backgrounder to test your iphone gcc and mobilesubstrate development environment
http://code.google.com/p/iphone-backgrounder/source/checkout

Install subversion before using svn in iPhone / iPod Touch

apt-get install subversion
svn checkout http://iphone-backgrounder.googlecode.com/svn/trunk/ iphone-backgrounder
cd iphone-backgrounder



I use this modified Makefile to compile iphone-backgrounder

HDRS := $(foreach dir,$(DIRLIST), $(wildcard $(dir)/*.h))
OBJS := $(SRCS:.mm=.o)

all: $(NAME).dylib

config:
ln -snf $(TOOLCHAIN) $(SYS_PATH)

# Replace 'iphone' with the IP or hostname of your device
install: config $(NAME).dylib
ssh root@iphone rm -f /Library/MobileSubstrate/DynamicLibraries/$(NAME).dylib
scp $(NAME).dylib root@iphone:/Library/MobileSubstrate/DynamicLibraries/
ssh root@iphone restart

$(NAME).dylib: $(OBJS) $(HDRS)

$(LDID) -S $@

%.o: %.mm
$(CXX) $(CXXFLAGS) $(INCLUDES) -c $< -o $@

clean:
rm -f $(OBJS) $(NAME).dylib


P.S. This is how to compile a standard c++ program in iPhone gcc

Compatible code for OS 2.2.1 and 3.0

Recently, the itts apple server has a number of changes and one of my favourite opensource app AppSales Mobile failed to get the sales data. It is now updated and thanks to the developer for the updating

http://github.com/omz/AppSales-Mobile/


However, the project was set to compile for SDK3.0, there are only a few changes that need to bring this app to be compatible to OS 2.2.1 and 3.0 at the same time.

Here are the steps involved

(1) Base SDK set to iPhone Device 3.0
(2) In Project Settings, iPhone OS Deployment Target set to iPhone OS 2.2.1
(3) Change the source code in RootViewController.m that have setFont or setImage methods, there are about 18 such changes to be done.


This is how to change the source code by adding respondsToSelector: test before using the deprecated method

---

change from


  [footer.titleLabel setFont:[UIFont systemFontOfSize:14.0]];


to


  if ( [footer respondsToSelector:@selector(setFont:)] ) {
    [footer setFont:[UIFont systemFontOfSize:14.0]];
  }
  else {
    [footer.titleLabel setFont:[UIFont systemFontOfSize:14.0]];
  }


---

change from

  cell.imageView.image = [UIImage imageNamed:@"Daily.png"];


to


  if ( [cell respondsToSelector:@selector(setImage:)] ) {
    cell.image = [UIImage imageNamed:@"Daily.png"];
  }
  else {
    cell.imageView.image = [UIImage imageNamed:@"Daily.png"];
  }


You may get warnings when build to actual 2.2.1 OS device, but this is normal. However, you cannot build to 2.2.1 Simulator.

The modified source is available here

Revision 20 is a modified source (as above) for version 2009/7

javacom change name

I have been asked by Sun Microsystems to change my App Store name to others stating that Javacom is an Unauthorized use of Java Trademark.



Obviously, I don't have the ability to counter with their request. But I have a few words to say

First of all, my name in App Store is javacom not Javacom
Second, Java and Java applet are not supported by official iPhone App Store app or web app.
Third, I did not program in Java, I only drink a cup of java when I do programming.

May be I have to drink milk instead.... Coffee may not be good for me

Picture Icon in email signature for iPhone

How to add CSS signature to your iPhone ?

The previous hack was to change the Preferences Settings for jailbreaked iPhone. But I have a better approach for non-jailbreaked iPhone, and with custom picture email signature as well. It works for 2.x firmware.

This will be a new functionality for my app Touch Dial Emoji (version 2.0) in App Store.
