How to create directory and change it's owner with the deb package

permissions package-management directory deb chown

133

Solution 1

You were right, you need a debian/my_package.postinst file to perform such operation:

#!/bin/sh

#DEBHELPER#

set -e

DIR="/var/log/my_package/"
USER="my_user"

mkdir -p ${DIR}    
if id -u ${USER} > /dev/null 2>&1; then    
    chown ${USER}:${USER} ${DIR}
fi

Note: The script checks if the user exists before calling chown.

Solution 2

You do not need to create a postinst script, but the solution is still a bit tricky. I use dh wildcard in debian/rules:

#!/usr/bin/make -f
%:
        dh $@

binary:
        dh $@

which does all the needed stuff. But I need to override some dir's ownership (lets call it data). So I must make some exception, I use special directives as follow:

    override_dh_install:
        dh_install   #calls default *.install and *.dirs installation
        install -d -o www-data -g www-data $(CURDIR)/debian/<package_name>/var/www/<something>/data

The data directory do not need to be in *.dirs file. But still there is one trick. Debhelper contains script dh_fixperms, which would fix ownership back to root, so we need to override too:

override_dh_fixperms:
    dh_fixperms --exclude data

That's all. Keep in mind the data dir does not count as a conffile, so it will be removed on package removal. If you need to make it a conffile, it is another story.

I want to call the controller function from view. This my view:

   <body>
   <div ng-app="appTable">
      <div ng-controller="Allocation">
         <button ng-click="add()"> Add </button> 
         <button ng-click="remove()">remove</button>
         <table>
            <th>
            <td>Date</td>
            <td>Project</td>
            <td>Release</td>
            <td>Feature</td>
            <td>Module name</td>
            <td>Hours spent</td>
            <td>Comment</td>
            </th>
            <tr ng-repeat="data in dataList">
               <td><input type="checkbox" ng-model="data.isDelete"/></td>
               <td>

This is script.

As you can see in the view I have called the postdata function of the controller.This function internally uses msg variable.But view is not printing value of this variable.I am very new to Aj. Please help.

What does I want to call controller function from view mean? This question is not clear
space earth about 7 years

I have postdata() function in my controller.I want to call this function from my view i.e. from HTML code.

bessarabov about 10 years

I'm extremely sorry, but this does not answer my question.
Sylvain Pineau about 10 years

Please explain why this postinst script does not answer your original question. I'm a bit puzzled now.
bessarabov about 10 years

I'm sorry that I haven't explain it in the proper manner. Your solution works fine and this is what I have implemented. But the docs say This generally means there is a problem with the Makefile. I understand this message that there is some other way to do it. And I want to find out what is the recomened way to do this task.
Sylvain Pineau about 10 years

The directory creation could be done in debian/rules which is the Makefile for debian packages. Since I didn't know your debian/rules I preferred to propose a solution based on a single file. But the chown command must be a post-installation process. debian/dirs should be avoided but my initial answer is perfectly fine. Please vote and accept it, thanks.

Does this require that the user and group exists on the system where the package is built? And if yes, is there a way to ensure that with a Debian-based mechanism?
space earth about 7 years

This thing is already I have done in my code.But it is not working
neptune about 7 years

@spaceearth if you resolved all the three issue I mentioned and still don't work, you should create an mcve to be easier to see what the problem is.
space earth about 7 years

I have tried that also,without using ng-controller="Allocation as vm",it prints function name as it is in output,like {{postdata(data.date)}}
anoop about 7 years

@spaceearth: you also need to inject $http in your controller, to make API calls, I edited my answer. check the fiddle link also
space earth about 7 years

I have seen your fiddle demo.But it is printing the Output Message,status code... empty.How to see console log in fiddle?
anoop about 7 years

@spaceearth : because I've commented the $http.post call, since I don't have your API. further if possible don't make post call on each iteration, try to accumulate your data and make 1 call
space earth about 7 years

I it is working.But it is continuously calling function.I want functionality like when submit button is called then only postData() function should be called. What should be done?
anoop about 7 years

Let us continue this discussion in chat.

This will create the directories on the system used to build the debian package, not the system the package is installed on.
kayn over 3 years

There is a typo. The ending should be postinst and not postint.
Alexis Wilke over 2 years

@moritz Yes. That is the drawback of this technique. It needs to exist on both systems.
Alexis Wilke over 2 years

I don't think that it makes sense to have a *.dirs and then use install -d ... since both create the directories. On my end, I simply use chown ... in the rules file.
