系統(tǒng)cvs to Git 遷移

遷移簡(jiǎn)介

應(yīng)用工具：cvs2git

工作原理：文件系統(tǒng)的copy, from cvs repository to export temp file, then import to Git repository.

使用條件: Git version 1.5.4.4 or later (我們的目標(biāo) git 庫(kù)版本：

git --version

git version 1.9.0

git --version
git version 1.9.0

cvs2git工具安裝

遷移過(guò)程

具體的遷移過(guò)程：

以下為遷移wxxr-core-framework

1. 在123.1上用cvs2git把cvs倉(cāng)庫(kù)，導(dǎo)出成git的備份文件（blob file and dump file）

• cvs2git --blobfile=/tmp/cvs2git/output/git-blob-cfw.dat --dumpfile=/tmp/cvs2git/output/git-dump-cfw.dat --username=zhangjunqing --fallback-encoding=GBK /app/cvsroot/wxxr-projects/wxxr-core-framework
• 創(chuàng)建本地git倉(cāng)庫(kù) 
  • git init --bare wxxr-core-framework.git

• 下載導(dǎo)出的git的備份文件到本地臨時(shí)目錄 **
  • cd /Users/zhangjq/temp/cvs2git
  • scp -r djboss@192.168.123.1:/tmp/cvs2git/output/git-* . 
• 用git的fast-import命令把從cvs導(dǎo)出的git備份文件導(dǎo)入剛創(chuàng)建的git倉(cāng)庫(kù)** cd /Users/zhangjq/git/wxxr-core-framework/wxxr-core-framework.git** cat /Users/zhangjq/temp/cvs2git/git-blob-cfw.dat /Users/zhangjq/temp/cvs2git/git-dump-cfw.dat | git fast-import
• 在Stash 上創(chuàng)建遠(yuǎn)程倉(cāng)庫(kù)** 創(chuàng)建了framework-core 倉(cāng)庫(kù)集，并在此倉(cāng)庫(kù)集下創(chuàng)建了wxxr-core-framework, wxxr-core-web  等遠(yuǎn)程倉(cāng)庫(kù)**http://developer.corp.wxxr.com.cn/git/projects/FRMCORE/repos/wxxr-core-framework/browse
  •  
• 在本地執(zhí)行** git branch -D TAG.FIXUP (執(zhí)行g(shù)it branch -a 沒(méi)有找到這個(gè)分支，為什么刪除？error: branch 'TAG.FIXUP' not found. )

• • git gc --prune=now

• • git remote add origin http://xxxxx@developer.corp.wxxr.com.cn/git/scm/frmcore/wxxr-core-framework.git

• • git push --all origin  (將本地的所有分支都推送到遠(yuǎn)程主機(jī))
  • git push -tags origin (最后，git push不會(huì)推送標(biāo)簽（tag），除非使用-tags選項(xiàng)。)
• 至此，完成了wxxr-core-framework的遷移。下一步執(zhí)行比較驗(yàn)證。

Git 時(shí)不時(shí)地將這些對(duì)象打包至一個(gè)叫 packfile 的二進(jìn)制文件以節(jié)省空間并提高效率。當(dāng)倉(cāng)庫(kù)中有太多的松散對(duì)象，或是手工調(diào)用git gc 命令，或推送至遠(yuǎn)程服務(wù)器時(shí)，Git 都會(huì)這樣做。

附：遷移腳本

遷移驗(yàn)證

用本地cvs代碼庫(kù)代碼與git下載的庫(kù)代碼比較，有$Revision$ 的少版本信息外，其它一切正常。

遷移報(bào)告

如何成為一名軟件架構(gòu)師？

Daniel Mohl是一名專業(yè)的軟件工程師/架構(gòu)師，他的興趣包括理解各種復(fù)雜的編程語(yǔ)言、企業(yè)應(yīng)用架構(gòu)以及如何搭建業(yè)務(wù)與技術(shù)，他通曉F#、C#、 CoffeeScript、JavaScript、Erlang、ASP.NET、MVC、WPF、WCF、Sliverlight、SQL Server等技術(shù)。有著多年的軟件開發(fā)經(jīng)驗(yàn)。

他經(jīng)常會(huì)被一些有潛力和有前途的程序員問(wèn)到：“我要怎么做才能成為一名架構(gòu)師？”說(shuō)實(shí)話，這已經(jīng)是老生常談的話題了，答案當(dāng)然是視情況而定。不過(guò)他也根據(jù)自己的經(jīng)驗(yàn)，給大家一些建議，并且提供一些資料，助你快速走上架構(gòu)師這條道路。

下面是Daniel Mohl所提出的列表，供大家參考：

首先，你必須不斷地尋求改善和提升自己。而提升自己的最好方法是閱讀，下面有幾本書，對(duì)我的軟件架構(gòu)技能的提升很大。推薦給大家：

• 軟件架構(gòu)師應(yīng)該知道的97件事
• 企業(yè)應(yīng)用架構(gòu)模式
• 敏捷軟件開發(fā)，原則，模式和實(shí)踐
• 企業(yè)集成模式
• JavaScript語(yǔ)言精髓
• 利用遺留代碼有效地工作
• 領(lǐng)域驅(qū)動(dòng)設(shè)計(jì)
• 企業(yè)架構(gòu)策略
• 設(shè)計(jì)模式（四人幫）
• The Goal
• SOA設(shè)計(jì)模式
• SOA Principles of Service Design

除了閱讀，還有沒(méi)有其他需要注意的、或者在平時(shí)需要關(guān)注的東西呢？

• 每隔一兩年學(xué)習(xí)一門新語(yǔ)言，F(xiàn)#是個(gè)不錯(cuò)的選擇。
• 選擇一個(gè)重點(diǎn)領(lǐng)域，但是盡可能對(duì)許多技術(shù)有個(gè)高層次的理解
• 對(duì)你所關(guān)注的重點(diǎn)領(lǐng)域，開通一個(gè)博客并且繼續(xù)拓展該領(lǐng)域的知識(shí)面，讓自己漸漸成為一名專家。
• 與不同的技術(shù)、編程語(yǔ)言、設(shè)計(jì)模式和結(jié)構(gòu)等（甚至是它并沒(méi)有在日常中給予你直接的幫助）打交道。你永遠(yuǎn)都不知道這些知識(shí)是否會(huì)在未來(lái)派上用場(chǎng)，但是對(duì)你絕對(duì)是有益無(wú)害。
• 根據(jù)你的目標(biāo)受眾來(lái)談?wù)?#8220;語(yǔ)言”。作為一名架構(gòu)師，你將會(huì)與各種各樣等級(jí)的人打交道，并且他們對(duì)技術(shù)的理解也會(huì)有所不同。所以要學(xué)會(huì)調(diào)整你的講解方式，做到因人制宜，讓他們能夠理解。
• 閱讀博客、觀看/參加Twitter或G+、聽播客、讀雜志、參加用戶小組會(huì)議和技術(shù)會(huì)議，并且在這些會(huì)議上踴躍發(fā)言。這些都會(huì)給你帶來(lái)無(wú)窮無(wú)盡的知識(shí)和樂(lè)趣，建立自己的“品牌”和提供交流機(jī)會(huì)。
• 紀(jì)律是關(guān)鍵。永遠(yuǎn)做你自己最喜歡的工作，即使它聽起來(lái)不那么有趣。每天安排時(shí)間學(xué)習(xí)一些新的東西，即使是15分鐘也可，千萬(wàn)不要被其他事情占用了這段時(shí)間。
• 開啟博客之旅。我發(fā)現(xiàn)，與閱讀比起來(lái)，把東西寫下來(lái)會(huì)讓你有更深入的理解。
• 利用好“閑暇時(shí)間”，這段時(shí)間可以拿本雜志讀讀，或者去聽聽播客等。
• 了解各種可用的開發(fā)工具，可以使架構(gòu)師的工作更好、更有效
• 看許多不同項(xiàng)目里的架構(gòu)
• 學(xué)習(xí)各個(gè)項(xiàng)目的管理方法
• 學(xué)習(xí)一些評(píng)估技術(shù)，對(duì)業(yè)務(wù)可以提供有價(jià)值的評(píng)估

上面是作者總結(jié)出來(lái)的列表，雖然看起來(lái)有點(diǎn)枯燥無(wú)味，但在整個(gè)軟件開發(fā)過(guò)程中是樂(lè)趣無(wú)窮的。如果你還有更好的建議，歡迎與我們分享。

}

Associations

 the Miner class we looked at was single table oriented, mapping to a single miners table. ORM solutions support ways to map associated tables to in memory objects ,
 

• Many to One/One to one - belongs_to/has_one
• One to Many (set) - has_many
• Many to Many (set) - has_and_belongs_to_many
• Single Table Inheritance
• Components (mapping > 1 object per table)

 As a comparative example, lets look at the many to one relationship. We are going to expand our Deadwood example from part I. We add to the Miner a many to one association with a GoldClaim object. This means there is a foreign key, gold_claim_id in the miners table, which links it to a row in the gold_claims table.

(Java)
public class Miner {
   // Other fields/methods omitted

    private GoldClaim goldClaim;
    /**//**
     * @hibernate.many-to-one column="gold_claim_id"
     *         cascade="save"
     */
    public GoldClaim getGoldClaim() { return goldClaim; }
    public void setGoldClaim(GoldClaim goldClaim) {
        this.goldClaim = goldClaim;
    }
}

 Transitive Persistence  
Its important for an ORM solution to provide a way to detect and cascade changes from in memory objects to the database, without the need to manually save() each one. Hibernate features a flexible and powerful version of this via declarative cascading persistence. 

Deleting Hibernate offers a number of different cascading behaviors for all associations types, giving it a high degree of flexibility. For example, setting cascade="all" will make GoldClaim save, update and delete along with its parent Miner, like so...

Miner miner = new Miner();
miner.setGoldClaim(new GoldClaim());
session.save(miner); // Saves Miner and GoldClaim objects.
session.delete(miner); // Deletes both of them.

Query Languages

 Hibernate has its own object oriented query language (Hibernate Query Language - HQL), which is deliberately very similar to SQL. How it differs is that it lets developers express their queries in terms of objects and fields instead of tables and columns. Hibernate translates the query into SQL optimized for your particular database. Obviously, inventing a new query language is very substantial task, but the expressiveness and power of it is one of Hibernate's selling points. 

Querying for Objects with HQL 
when you have to start navigating across objects with SQL, HQL can be very convenient alternative. Let's take a look at our sample queries for HQL.

// Find first Miner by name
Query q = session.createQuery("from Miner m where m.firstName = :name");
q.setParameter("name", "Elma");
Miner m = (Miner) q.setMaxResults(1).uniqueResult();

// Finds up to 10 miners older than 30, ordered by age.
Integer age = new Integer(30);
Query q = session.createQuery(
    "from Miner m where m.age > :age order by age asc");
List miners = q.setParameter("age", age).setMaxResults(10).list();

// Similar to join query above, but no need to manually join
Query q = session.createQuery(
   "from Miner m where m.goldClaim.squareArea = :area");
List minersWithSqA = q.setParameter("area", new Integer(1000)).list();

 Having covered some of the basics of fetching objects, let's turn your attention to how we can make fetching objects fast. The next section covers the means by which we can tune the performance. 

Performance Tuning

 Beyond just mapping objects to tables, robust ORM solutions need to provide ways to tune the performance of the queries. One of the risks of working with ORM's is that you often pull back too much data from the database. This tends to happen because it its very easy to pull back several thousand rows, with multiple SQL queries, with a simple statement like "from Miner". Common ORM strategies for dealing with this include Lazy fetching, outer join fetching and caching. 

What I mean by lazy is that when you fetch an object, the ORM tool doesn't fetch data from other tables, until you request the association. This prevents loading to much unneeded data.  Hibernate allows you to choose which associations are lazy.  This leads us to one of the great fallacies of ORM, that Lazy loading is always good. In reality, lazy loading is only good if you didn't need the data. Otherwise, you are doing with 2-1000+ queries what you could have done with one. This is dreaded N+1 select problem, where to get all the objects require N selects + 1 original selects. This problem gets much worse when you deal with collections..

Outer Joins and Explicit Fetching

Generally, one of the best way to improve performance is to limit the number of trips to the database. Better 1 big query than a few small ones. Hibernate has a number ways its handles the N+1 issue. Associations can be explicitly flagged for outer join fetching (via outer-join="true"), and you can add outer join fetching to HQL statements. For example...

/**//**
* @hibernate.many-to-one column="gold_claim_id"
*           cascade="save-update" outer-join="true"
*/
public GoldClaim getGoldClaim() { return goldClaim;  }

// This does one select and fetches both the Miner and GoldClaim
// and maps them correctly.
Miner m = (Miner) session.load(Miner.class, new Long(1));

// Issues a single select, instead of 1 + N (where N is the # miners)
List list = session.find("from Miner m left join fetch m.goldClaim");

While object caching isn't always going to be helpful or a performance silver bullet, Hibernate has a huge potential advantage here. It provides several levels of caching, including a session (UnitOfWork) level as well as an optional second level cache. You always use the '1st level' cache, as it prevents circular references and multiple trips to the database for the same object. Using a second level cache can allow much of the database state to stay resident in memory. This is especially useful for frequently read and reference data.
