bzr branch http://bazaar.launchpad.net/~bzr-gtk/bzr-gtk/trunk ~/.bazaar/plugins/gtk

./python
import sys
print sys.path
(prints dirs in which modules will be searched )

To install PyGTK  python modules do:
export PYTHON=/home/thava/linux/Python-2.5.2/python
#export PYTHONPATH=lib/pythonX.Y/site-packages

``bzr checkout https://launchpad.net/bzr-email ~/.bazaar/plugins/email``.

Get this branch: bzr branch lp:~cdleary/bzr-email/bzr-email-ssmtp  
SSMTP is manually enabled by putting "smtp_ssl_enabled = 1" under the appropriate heading in ~/.bazaar/locations.conf -- port 465 is assumed.


What is the diff between bzr init-repo and bzr init ?
   bzr init-repo repo creates repository -- repo/.bzr/repository/ created
   bzr init proj creates project -- proj/.bzr/branch/ created

How to put an existing project into bazaar ?
cd my-stuff
bzr init    # creates .bzr for project
bzr add     # Adds all files in . and subdirs!
bzr commit -m "Initial import"   # local commits all files!

Can you create project without repository created first?
  yes, but that is not efficient.

Are there repository wide config options available ?
  No, there are no .conf files available at repository level.


How to make bazaar ignore files?
    Create .bzrignore at top of project and put lines like: *.o *.tmp (one per line)

How to see the list of files changed in workspace?
    bzr status
    bzr diff    # with no args! It displays diff for all files changed!

How to checkin locally ?
    bzr commit -m "local commit message"

How to graphically view the history of files ?
    bzr qlog # from QBzr plugin
    bzr viz  --limit=5 # from gtk plugin; Must to use!

How to package release?
    bzr export ../releases/myproj.tar.gz

What is plugin search order?
Bzr will scan bzrlib/plugins and ~/.bazaar/plugins for plugins by default. You can override this 
with BZR_PLUGIN_PATH.



Steps to configure your own repository and mail system:

cd /home/thava/bzr
bzr init myproj
cd myproj
touch myfile
bzr add myfile
bzr commit -m "Myfile added"

branch.conf:
[DEFAULT]
allow_remote_options = mysql
email = Thava Alagu <thavamuni.alagu@sun.com>
per_file_commits = On
post_commit_mailer = smtplib

locations.conf:
[/home/thava/bzr/myproj]
post_commit_to = Thava Alagu <thavamuni.alagu@sun.com>
post_commit_sender = Thava Alagu <thavamuni.alagu@sun.com>

Bzr FAQ:

========================================================================
   How to list changes in a bug ?

   Go to bugs.mysql.com Lookup the bug.
   The patch and the commit mailing list threads are listed there.
   You can also directly search messages : lists.mysql.com/commits

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

   How to list the changes in certain version ?

e.g. I want to see the changes done in bug #42610
     First I do: bzr log  sql_plugin.cc 
     and searched for #42610 :

e.g.         ------------------------------------------------------------
        revno: 2497.752.1
        committer: Sergey Glukhov <gluh@mysql.com>
        branch nick: mysql-5.1-bugteam
        timestamp: Mon 2009-02-09 19:03:52 +0400
        message:
          Bug#42610 Dynamic plugin broken in 5.1.31
          added ignore-builtin-innodb option which disabled
          initialization of builtin InnoDB plugin

    bzr log -v -r 2497.752.1

       Gives a list of files modified in this version!!!

    (and -c or -r option added)
 


What is NULL merge ?
You can do:

  bzr merge ../other
  bzr revert .
  bzr commit -m "Fake merge of other to reject the changes"

The important part is the "." which tells "bzr revert" that you want to revert the changes to the files, but leave the "I merged this other branch" flag.
