After learning a bit of programming, I was attracted by the networking world. I got from petty Pascal/C++ projects through web development using ugly PHP and later Python, to a freelancing work with most of the projects in server administration, network equipment configuration and a bit of programming. Most people in the business know me from my conference talks and articles.
After learning a bit of programming, I was attracted by the networking world. I got from petty Pascal/C++ projects through web development using PHP and later Python, to years of freelancing work with most of the projects in server administration, network equipment configuration and a bit of programming. I was active in the community, wrote articles and spoke at conferences which finally led to my joining Red Hat in May 2012 to work on NetworkManager. I was already a Fedora user and package maintainer at that time. Since August 2013 I'm working on various network related packages and projects.


One of my conference talk brought me an offer from Red Hat, which I joined in May 2012 to work on NetworkManager. I was already a Fedora user and package maintainer at that time. Since August 2013 I'm no longer working as a regular NetworkManager developer (staying an upstream contributor, though). Even before that I tried to put my hands on a number of other projects via bug reports, tests and code. I'm also interested in various network-related standards and especially bugs and bad assumptions in IETF documents.

Use the above technique to prepare rawhide if branches can't be fast forwarded to rawhide.

<pre>
** Missing for IPv6 link-local addresses.

** IPv6 disabled by default.
** Problems with duplicates in discovery.
* glibc
** The getaddrinfo() support is very complicated while not giving correct results in ''many'' cases.
* kernel
** Network configuration is a real pain.
** Kernel IPv6 autoconfiguration is only designed for trivial use cases and is very buggy.
* libnl
** Most of the advanced stuff is very buggy.

About

After learning a bit of programming, I was attracted by the networking world. I got from petty Pascal/C++ projects through web development using PHP and later Python, to years of freelancing work with most of the projects in server administration, network equipment configuration and a bit of programming. I was active in the community, wrote articles and spoke at conferences which finally led to my joining Red Hat in May 2012 to work on NetworkManager. I was already a Fedora user and package maintainer at that time. Since August 2013 I'm working on various network related packages and projects.

Simple maintainance tasks

Make a fix and a build

bug=123456
message="do something"

# ... add/modify files ...
rpmdev-bumpspec *.spec -c "Resolves: #$bug - $message"
fedpkg commit -c
# ... check using gitk ...
fedpkg push && fedpkg build

Make a scratch build from locally generated SRPM

fedpkg build --scratch --srpm

Bump a rawhide package to a newer version

In the package git directory:

version=...

# Prepare a commit
fedpkg switch-branch master
rpmdev-bumpspec --new="$version" --comment="new version $version" *.spec
spectool -g *.spec && fedpkg new-sources `spectool -l *.spec | grep / | sed 's/.*\///'`
fedpkg commit -c

# Test it
fedpkg build --scratch --srpm

# Create a public build
fedpkg push && fedpkg build

Patchwork

Using vim

Open three panes containing (1) patch to be edited, (2) patched file and (3) rejected hunks.

package=...
version=...
patch=...
file=...

vim -O $patch $package-$version/$file{,.rej}

Using git

Warning: Untested. I used a similar command but lost it.


package=...
version=...
dir=/path/to/upstream/workdir

(echo cd $dir; for patch in `awk '/^Patch[0-9]*: / { print $2 }' *.spec`; do echo -n "git apply --index "; realpath $patch; echo git commit -m $patch; done) | sh

New package

Create a local Git repository

package=...
editor=...

git init $package
cd $package

$editor $package.spec
git add $package.spec

fedpkg new-sources `spectool -l *.spec | grep / | sed 's/.*\///'`

rpmdev-bumpspec $package.spec -m 'initial build'
fedpkg commit -c

Create a review request

rawhide=f22

fedpkg --dist $rawhide srpm
fedora-create-review --no-scratch-build *.spec *.src.rpm

Update a review request

rawhide=f22
message="incorporated review feedback"

rpmdev-bumpspec *.spec -m "$message"
fedpkg commit -c

fedpkg --dist $rawhide srpm
fedora-create-review --amend --no-scratch-build *.spec *.src.rpm

Requires:

Review a new package

System configuration:

yum install @fedora-packager fedora-review
ln -s /etc/mock/fedora-devel-x86_64.cfg /etc/mock/default.cfg

mockuser=...

usermod -a -G mock $mockuser

Review local files:

name=...

fedora-review -n $name

Review bugzilla:

bz=...

fedora-review -b $bz
