Good Commit Messages And Enforcing Them With Git Hooks

I have used GIT for a year, commit and push hundreds of commits. However I still forgot our GIT naming convention and push a wrong commit last week. I wonder if there is a tool for checking the commit message before I press commit button.

Fortunately, GIT provides us many powerful hooks to do this. After two hours searching in Google, I found an awesome sample which is written by python but I prefer perl than python so I decide to write my own perl script.

 

 

 

Then, I copy perl.exe from my install git folder to .git/hooks

Finally, I modify the script commit-msg to call my perl script:

exec .git/hooks/perl.exe .git/hooks/check-commit-message.pl $1

Now, everytime I make a commit, the hook commit-msg will run and check my commit message

 

How to suppress a rule on FxCop

Please follow the steps below to suppress:

2. Add new GlobalSuppressions.cs file to Properties folder on your project.
3. Using Microsoft FxCop tool to get quickly correct a SuppressMessage:

• Start Menu -> All Programs -> "Microsoft FxCop" option and then click on FxCop

• Go to Project Menu and click on “Add Targets…”. Select the EXE or DLL. Once it is done, click on Analyze button and your screen will look like below:

• Right click on any message you want to suppress and go to Copy As ->Suppress-Message or Copy As ->Module-level Suppress Message.

How to truncate git history by Git Extension

After a year working with project Legend, our team created about 1400 commits. However I don’t think anyone need to view the commit history of six or twelve months ago, so I would like to truncate too old commits.

If you love command line, you can use following awesome git commands:

 git checkout --orphan temp $1
 git commit -m "Truncated history"
 git rebase --onto temp $1 master
 git branch -D temp
 git gc

I’m a fan of GIT extension so I try converting those commands to Git Extension actions:

1. Open your git directory with Git extension

 

2. Create a temp branch at the last commit you would like to truncate

3. Reset MIX to the root commit

 

 

4. Amend commit with new message “Truncate 3 commits”

5. Check out master, rebase on temp

6. Enjoy the result, your old commit has been truncated

Draw Git history graph by HTML5

If you have intention to draw a GIT history graph in HTML you might think about HTML5.

In this example, I use NGIT to get GIT history graph information. I added SimpleAbstractPlotRenderer to namespace NGit.Revplot (because AbstractPlotRenderer doesn't work correctly) and created an override class SimplePlotRenderer to render history graph information. Finally, I use easelJs to draw GIT History graph

Build Summary plugin for Jenkins

I have used Jenkins as main tool of CI for 6 years. Jenkins helps me so much for monitoring the stability of my source code. When I received failed message from Jenkins, I understood that there was something wrong. Then I read the console log to find out the problem and fixed it immediately.

 

 

However it is inconvenience to read a long console log so I looked for a way to summarize the status of my build. Fortunately, Thommas has given me a very useful plugin: Summary Display
 
I set up and configured the plugin as Thommas said then I copied the xml file to the artifact directory but nothing happen. The summary build report shows empty.

 

I read the wiki again and I realized that I haven’t created the right format xml. The xml file must similar as the full section example:

Now I can enjoy Summary Display plugin


 
 
 

 
 

 

Minify HTML with ASP.Net MVC 4 - Razor

Several months ago, my boss asked me to create a 5000 rows report. After I solved all problems related to business and server side performance, I’m still not satisfied with the HTML size. My report has to download about 20Mb HTML. Thank god, I can use gzip to make it smaller than 1MB. However I still think I can make it smaller by removing all unneeded whitespaces, similar as the minified javascript.
I found a solution in Arran Maclean’s blog. He used Action Filter to remove all unneeded whitespaces after ASP.MVC 4 render the html files.
His Action Filter renders the perfect minified html file, all unneeded whitespaces are removed. However, I think it consumes a little memory and CPU resource to remove all whitespaces of a 20MB file.
Why we don’t remove the whitespace of razor view? I have researched several hours in Google but nobody thought like me. So I decide to write small winform application to remove all whitespace of my razor view before I deploy my project.
 

The original Razor view:

The Razor view hash been removed whitespaces:

Here are my test results.

The “No trimming” section indicating that the server returns a 11.1MB file in about 1.85-3.45 seconds. The “Runtime trimming” section indicating that the server removes all whitespaces by Action Filter and returns a 6.4MB file in about 3.36-4.07 seconds. The last section indicating that the server renders HTML from a minified razor view and returns a 6.5MB file in 1.35-2.71 seconds.
My application doesn’t have the best algorithm to minify the razor view so I can’t afford the best result. However my solution reduces a little consumed resource of server
