svn-buildpackage

by tangke 2009-10-20

svn-buildpackage的作用是在debian包基础上面添加svn的支持。
我开始的时候一直以为是在svn的基础上面添加debian的包支持，看来是弄错了，因为对于svn-buildpackage的包都必须是通过svn-inject处理过的，而且debian包需要的一些文件比如debian/control, debian/changelog等等在svn-buildpackage的包里面都没有发现，所以我断定应该是在debian包基础上面添加svn的支持。

1.svn-inject

我们可以使用svn-inject将debian的包文件代码添加到svn server中
具体使用办法:
svn-inject *.dsc svn://127.0.0.1:/pppoe_loongson
然后要求输入用户名和密码

然后进入/tmp
svn co svn://127.0.0.1:/pppoe_loongson
cd pppoe_loongson
看到里面有两个目录tags和trunk
trunk目录中存放着一些代码文件，如src,debian等目录

2.svn-upgrade

vi trunk/.svn/deb-layout
upsTagUrl=file:///home/tangke/Work/svn_repo/pppoeloongson/pppoeloongson
upsCurrentUrl=/tmp/pppoeloongson/pppoeloongson/
cd trunk
tangke@tangke-laptop:/tmp/pppoeloongson/pppoeloongson/trunk$ svn-upgrade -V "r2" ./
    upsTagUrl: file:///home/tangke/Work/svn_repo/pppoeloongson/pppoeloongson
    upsCurrentUrl: /tmp/pppoeloongson/pppoeloongson/
Complete layout information:
    buildArea=/tmp/pppoeloongson/pppoeloongson/build-area
    tagsDir=/tmp/pppoeloongson/pppoeloongson/tags
    tagsUrl=file:///home/tangke/Work/svn_repos/pppoeloongson/pppoeloongson/tags
    trunkDir=/tmp/pppoeloongson/pppoeloongson/trunk
    trunkUrl=file:///home/tangke/Work/svn_repos/pppoeloongson/pppoeloongson/trunk
    upsCurrentUrl=/tmp/pppoeloongson/pppoeloongson/
    upsTagUrl=file:///home/tangke/Work/svn_repo/pppoeloongson/pppoeloongson
 ( cd "/tmp/pppoeloongson/pppoeloongson" ; tar c "trunk" )  | gzip -9 > "/tmp/tmp.eWtoui4YVK/pppoeloongson_r2.orig.tar.gz"
svn up

         Could not find the unmodified upstream version in
         file:///home/tangke/Work/svn_repo/pppoeloongson/pppoeloongson/0.6lemoteubuntu2!
         If you think that /tmp/pppoeloongson/pppoeloongson/ is the upstream source
         which file:///home/tangke/Work/svn_repos/pppoeloongson/pppoeloongson/trunk is based on, run:

         svn copy /tmp/pppoeloongson/pppoeloongson/ file:///home/tangke/Work/svn_repo/pppoeloongson/pppoeloongson/0.6lemoteubuntu2

         Otherwise, please fix the headline of debian/changelog.

然后我们回到pppoe_loongson目录
svn update
就可以看到0.6lemoteubuntu2就被更新到tags目录了

3.svn-buildpackage

然后出现一个printf错误，重新修改src/main.cpp
加入#include
再执行svn-buildpackage发现错误，好像需要和上游版本进行同步才可以,错误如下:

make[1]: Leaving directory `/tmp/pppoe_loongson/pppoeloongson/trunk'
dh_clean
E: Found unresolved issues:

M       src/main.cpp

E: Resolve them manually before continuing

svn commit -m "test"
然后再svn-buildpackage
OK,执行成功

这样会多出来两个目录tarballs和build-area目录，
build-area目录中就存放了打好的deb包等等，以及一些dsc,tar.gz,deb包等文件，还有一个目录，里面也存放了一个代码系统，可能是一个用来编译的临时目录吧，这样就可以不破坏整个源码目录了.


这里需要注意的是：
1.必须是经过svn-inject上传的svn版本才可以进行svn-buildpackage,这是必须的。
因为这样可能符合svn-buildpackage打包结构吧，比如你在上传的时候没有tags或者trunk目录的话，可能就会出错。
2.svn-buildpackage命令必须在trunk目录下面执行。

3.svn-upgrade

cd trunk目录
svn-upgrade -V "r46" ./
tangke@tangke-laptop:/tmp/pppoe_loongson/pppoeloongson/trunk$ svn-upgrade -V "r46" ./

upsTagUrl setting is required, but could not be found in /tmp/pppoe_loongson/pppoeloongson/trunk/.svn/deb-layout or repository tree.

以上问题主要是因为没有设置upsTagUrl和upsCurrentUrl这两个环境变量，可以按照上面的在.svn/deb-layout里面添加

4.svn-buildpackage --svn-tag
To build a package and make a tag for release:
出现错误:
dh_clean
UNRELEASED tag found - you don't want to release with it, do you?
Aborting now, set $FORCETAG to ignore it.

export FORCETAG=1
svn-buildpackage --svn-tag
会自动在debian/changelog里面版本增加
当然我们可以使用
svn-buildpackage --svn-tag --svn-noautodch
这样changelog就不会自动增加了
