在前文中，基於git介紹了webrev工具。實際上，webrev工具還支援hg和svn。最近的工作中不可避免地要使用svn，故在此總結一下如何基於svn在Linux上建立webrev。順便吐個槽，沒有網頁版的代碼比對，用svn diff簡直就是刀耕火種茹毛飲血啊！技術再嫻熟的老司機，也架不住讓你在高速公路上開拖來機Orz！

以前工作上一直用版本管理工具Mercurial (命令為hg), 個人學習的話用Git, 但從來沒用過Subversion (命令為svn等) 。所以，下面的先簡單介紹一下如何搭建一個svn的server然後初始化一個代碼倉庫。相比之下，基於Mercurial的代碼倉庫初始化實在是太容易了，只需要一條命令(hg init .)搞定。

1. 搭建一個svn的server

1.1 建立一個項目venus

root# cd /var/tmp && mkdir ducertroot# svnadmin create venus

1.2 設定項目venus

root# tree venus/confvenus/conf├── authz            #<-- 許可權相關的配置├── hooks-env.tmpl├── passwd           #<-- 帳號相關的配置  └── svnserve.conf    #<-- 資產庫相關配置0 directories, 4 files

1.2.1 配置帳號 e.g. 添加使用者veli， 密碼為veli (見第9行)

root# cat -n passwd     1### This file is an example password file for svnserve.     2### Its format is similar to that of svnserve.conf. As shown in the     3### example below it contains one section labelled [users].     4### The name and password for each user follow, one account per line.     5     6[users]     7# harry = harryssecret     8# sally = sallyssecret     9veli = veli

1.2.2 配置許可權 e.g. 給使用者veli的是可以在/下面進行讀寫 (見第34和35行)

root# cat -n authz     1  ### This file is an example authorization file for svnserve.     2  ### Its format is identical to that of mod_authz_svn authorization     3  ### files.   ...    33    34  [/]    35  veli=rw

1.2.3 配置資產庫 e.g. 設定程式碼程式庫的根目錄(見第48行) （第19,20,27,36行只需要把對應的注釋符號去掉即可）

root# cat -n svnserve.conf      1  ### This file controls the configuration of the svnserve daemon, if you     2  ### use it to allow access to this repository.  (If you only allow     3  ### access through http: and/or file: URLs, then this file is   ...    19  anon-access = read    20  auth-access = write   ...    27  password-db = passwd   ...    36  authz-db = authz   ...    48  realm = /var/tmp/ducert/venus   ...

1.3 啟動svnserver (e.g. svnserve -d -r venus)

root# cd /var/tmp/ducert && pkill svnserveroot# svnserve -d -r venusroot# ps -ef | grep venus | grep -v greproot      6960  2233  0 11:29 ?        00:00:00 svnserve -d -r venusroot# netstat -an | grep 3690tcp        0      0 0.0.0.0:3690            0.0.0.0:*               LISTEN

1.4 測試svn server "venus" 可以正常工作

1.4.1 checkout

veli$ ifconfig -a | egrep "inet addr:.*255.255.255.0"          inet addr:192.168.228.128  Bcast:192.168.228.255  Mask:255.255.255.0veli$ svn co svn://192.168.228.128 --username=veli --password=veliChecked out revision 0.veli$ ls -A.svn

1.4.2 add some files

veli$ cd /tmp && mkdir sandbox && cd sandboxveli$ svn mkdir demoA         demoveli$ cd demoveli$ svn add foo.cA         foo.cveli$ svn add bar.pyA         bar.pyveli$ svn add MakefileA         Makefileveli$ svn statusA       .A       MakefileA       bar.pyA       foo.c

1.4.3 commit

veli$ svn commit -m "05/15/2017: init demo"Adding         .Adding         MakefileAdding         bar.pyAdding         foo.cTransmitting file data ...Committed revision 1.

到此為止，一個svn server就搭建好了，並且可以很流暢地工作了。接下來，使用webrev工具建立代碼比對網頁。因為在前一節已經介紹了如何下載webrev工具，這裡就不再多說了，直接使用就好。

2. 使用webrev建立代碼比對網頁

2.1 checkout svn庫裡的demo代碼

veli$ rm -rf /tmp/sandbox && mkdir /tmp/sandboxveli$ cd /tmp/sandboxveli$ svn co svn://192.168.228.128 --username=veli --password=veliA    demoA    demo/bar.pyA    demo/MakefileA    demo/foo.cChecked out revision 1.

2.2 修改檔案

veli$ cd /tmp/sandbox/demoveli$ vi foo.cveli$ svn diff foo.cIndex: foo.c===================================================================--- foo.c       (revision 1)+++ foo.c       (working copy)@@ -3,7 +3,7 @@ int main(int argc, char *argv[]) {-       (void) printf("Hello World!\n");+       printf("Hello World!\n");        return 0; }veli$ vi bar.pyveli$ svn diff bar.pyIndex: bar.py===================================================================--- bar.py      (revision 1)+++ bar.py      (working copy)@@ -4,9 +4,9 @@ def main(argc, argv):         print "Hello World!"+         return 0 if __name__ == ‘__main__‘:-        argv = sys.argv-        argc = len(sys.argv)+        argc, argv = len(sys.argv), sys.argv         sys.exit(main(argc, argv))veli$ vi Makefileveli$ svn diff MakefileIndex: Makefile===================================================================--- Makefile    (revision 1)+++ Makefile    (working copy)@@ -1,7 +1,7 @@ CC     = gcc CFLAGS = -g -Wall -m32-all: foo+all: foo bar foo: foo.o        $(CC) $(CFLAGS) -o [email protected] $<@@ -9,7 +9,12 @@ foo.o: foo.c        $(CC) $(CFLAGS) -c $<+bar: bar.py+       cp $< [email protected]+       chmod +x [email protected]+ clean:        rm -f *.o clobber: clean-       rm -f foo+       rm -f foo bar+cl: clobber

2.3 建立webrev

veli$ export PATH=/var/tmp/webrev/bin:$PATHveli$ webrevWARNING: codereview(1) not found.   SCM detected: subversion File list from: svn status ...  Done.
