using svk and trac

1.tool used for distributed development
2.powerful with diff,patch,kompare
3.svk steps
create a symbolic directory structure of remote svn to local its called mirror
checkout a project from mirror to a local folder its called workcopy
do modification on workcopy
push to mirror
push from mirror
reference links

4.setup anatomy query commands
svk info
svk list
5.svk installation asks for perl:time module...needs to get it from web

6.created svkdepot folder --mirror/local
7.at same level created svkwork folder --local checkout

6.using trac
http://trac.edgewall.org/wiki/TracUbuntuMultipleProjects

7.created svnrepo folder
8.at same level created trac-env folder
//apache.conf
========================================

============================================

8.TracEnv and TracEnvParentDir are used for single and MultipleProjects

9.Add gitplugin and doxygen plugin

10.Integrate wiki and scribd and google doc

firefox,file:///

1.in the profiles folder(find out by using error console) create user.js

3.clear the cache and all
4.open a new instance
5.check prefs.js if the entries are copied from user.js
6.execute

trac setup

1.install all the required modules ...python,perl,apache2
2.create trac environment using trac-admin into a local folder
3.note if trac is setup for single project or multiple projects(TracEnv,TracEnvParentDir)
4.add entries to /etc/apache2/apache2.conf ......
5.add auth entries also to it
6.test it using tracd
7.test on localhost http

git svn trac

1.most repos are svn client/server
2.git is repo type ,it adds more features
3.git-svn is a git wrapper over svn client,the server is still svn server
4.trac is a utility that builds features over the svn source base
5.trac git-plugin build features over the trac server

barrier ... cont

1.we have statements

stmt1;
stmt2;
------marker
'mystmt'
stmt3;

here the programmer is of the assumption that by the time control reaches marker
the 2 statements are finished completely and stmt3 would be a new sequence of commands
we can safely put since our assumptions are right here
But we are seeing the code from a code space angle
the code internally is generated by compiler , that is not bound by any strict criteria
for optimization it can reorganize codes in different ways
ie some of the side effects of stmt1 and 2 would be executed after stmt3
this can create serious problem when critical mystmts are executed with assumptions
