You need to install the `git-email` package for it to work.  

On `Ubuntu`, the usual `apt-get install git-email` works fine. I can confirm the same for `Fedora` as well (`yum install git-email`).    

	
[cebewee](https://stackoverflow.com/users/647987/cebewee) mentions the rationale in the comments:

&gt; Linux distributions often like to split up packages to avoid
&gt; dependencies needed only by optional functionality (like send-email).

Note that you have to [configure](http://blog.bisect.de/2012/01/how-to-send-patches-via-git-send-email.html) it before starting.

In the [Doctrine docs][1] they mention that there exists a few different strategies for the `@GeneratedValue` annotation:

 - `AUTO`
 - `SEQUENCE`
 - `TABLE`
 - `IDENTITY`
 - `UUID`
 - `CUSTOM`
 - `NONE`

Would someone please explain the differences between all thees strategies?

I need to insert JSON data from tornado to postgres, so here&#39;s test like this:

    from psycopg2 import connect
     
    conn = connect(&quot;user=&#39;pguser&#39; host=&#39;localhost&#39; dbname=&#39;pgdb&#39; password=&#39;pgpass&#39;&quot;)
    cursor = conn.cursor()
    
    data = &#39;[{&quot;id&quot;:&quot;sdf&quot;,&quot;name&quot;:&quot;wqe&quot;,&quot;author&quot;:&quot;vb&quot;}]&#39;
    
    for row in eval(data):
      print row
      cursor.execute(&quot;&quot;&quot;INSERT INTO books(id,name,author) VALUES(&#39;%s&#39;,&#39;%s&#39;,&#39;%s&#39;)&quot;&quot;&quot; % \
    		(row[&#39;id&#39;], row[&#39;name&#39;], row[&#39;author&#39;])
      )
    
    &gt;&gt;&gt; cursor.execute(&quot;SELECT * FROM books&quot;)
    &gt;&gt;&gt; cursor.fetchall()
    [(&#39;sdf&#39;, &#39;wqe&#39;, &#39;vb&#39;)]
    &gt;&gt;&gt; 
    $&gt; psql -d pgdb -U pguser -W
    Password for user pguser: 
    psql (9.1.6)
    Type &quot;help&quot; for help.
    
    pgdb=&gt; select * from books;
     id | name | author 
    ----+------+--------
    (0 rows)


As you can see after doing `select` in python shell, there&#39;s some data, but in psql there&#39;s
0 rows! What may I be doing wrong?

I am using Git subtree with a couple of projects that I am working on, in order to share some base code between them. The base code gets updated often, and the upgrades can happen in anyone of the projects, with all of them getting updated, eventually.

I have ran into a problem where git reports that my subtree is up to date, but pushing gets rejected. For example:

    #! git subtree pull --prefix=public/shared project-shared master
    From github.com:****
    * branch            master     -&gt; FETCH_HEAD
    Already up-to-date.

If I push, I should get a message that there is nothing to push... Right? RIGHT? :(

    #! git subtree push --prefix=public/shared project-shared master
    git push using:  project-shared master
    To git@github.com:***
    ! [rejected]        72a6157733c4e0bf22f72b443e4ad3be0bc555ce -&gt; master (non-fast-forward)
    error: failed to push some refs to &#39;git@github.com:***&#39;
    hint: Updates were rejected because the tip of your current branch is behind
    hint: its remote counterpart. Merge the remote changes (e.g. &#39;git pull&#39;)
    hint: before pushing again.
    hint: See the &#39;Note about fast-forwards&#39; in &#39;git push --help&#39; for details.

What could be the reason for this? Why is pushing failing?

Why can&#39;t I push this up-to-date Git subtree?

How do I fetch upstream repo and make it replace master? I only have one branch on my repo, which is master, and I completely messed it up, so I basically need to start over from the upstream. I think init will do the job, but is there an easier way?

git discard all changes and pull from upstream

Is it possible to create a new repository in Bitbucket by using command line Git? I have tried the following:

    git clone --bare https://username@bitbucket.org/username/new_project.git

I get this message:
    
&gt; Cloning into bare repository &#39;new_project.git&#39;...  
&gt; fatal: `https://username@bitbucket.org/username/new_project.git/info/refs` not found: did you run git update-server-info on the server?

It would be nice to do this without going to the web app.

I&#39;m having trouble performing a cherry-pick. On my local machine, I&#39;m currently on my &quot;master&quot; branch. I want to cherry-pick in a commit from another branch, named &quot;zebra&quot;. The &quot;zebra&quot; branch is a remote branch. 

So git status:

    # On branch master
    nothing to commit (working directory clean)

Ok, now I try to cherry-pick the commit I want:

    git cherry-pick xyz
    fatal: bad object xyz

where &quot;xyz&quot; is the signature of the commit I&#39;m interested in, that happened on branch &quot;zebra&quot;.

So the first obvious question is, why can&#39;t git find the commit I&#39;m referencing? I don&#39;t really understand how this is working in the first place to be honest. Does git store something like a database of commits locally in my working directory, for all other branches? When executing the cherry-pick command, does it go and search that local database to find the commit I&#39;m talking about?

Since &quot;zebra&quot; is a remote branch, I was thinking I don&#39;t have its data locally. So I switched branches:

    git checkout zebra
    Switched to branch &#39;zebra&#39;

So now here on my local machine, I can see that the files in the directory reflect zebra&#39;s state correctly. I switch back to master, try to cherry-pick again (hoping the commit data is available now), but I get the same problem.

I&#39;ve got a fundamental misunderstanding of what&#39;s going on here, any help would be great.


How to cherry-pick from a remote branch?

I just upgraded to Git 1.8.0.1 for Windows, from my previous version `1.7.9.mysysgit.0`. I downloaded the [new version from the Git site][1] and installed through the normal Git installer EXE.

That said, when I fire up my terminal window, it still is showing that I am running Git version `1.7.9.mysysgit.0`. When I type `git --version` from my prompt, the same thing.

I found [this article on a similar issue with Git on Mac&amp;nbsp;OS&amp;nbsp;X][2], which leads me to believe that it has something to do with a faulty `PATH`, but I&#39;m still pretty new at all this (five months self-taught), so I&#39;m at a loss in how to translate this to Windows.

This problem arose when I began a new [Ruby on Rails][3] project and tried to push it up to Git. I added the remote:

    git remote add origin git@github.com:brianscottk/blog.git

then:

    git push -u origin master

I received the following error message:

&gt; *fatal: https://github.com refs not found: did you run git update-server-info on the server?*

Googling that error led me to [this article][4], which prompted me to upgrade, and here I am.
