Centmin Mod 123.08stable was first release to use the new centmin.sh menu option 23 for git based update of Centmin Mod code as outlined at centminmod.com/upgrade.html. Just thinking out aloud on possible improvements in efficiency for centmin.sh menu option 23.

--------------------------------------------------------

The full git clone method gets larger and larger in size due to git clone by default pulling all Centmin Mod github branches and history as well Branches · centminmod/centminmod · GitHub So I am thinking of reworking centmin.sh menu option 23 so that it only pulls the specific branch needed rather than all the branches. It means for centmin.sh menu option 23 submenu option 3 for switching branches, I can not rely on listing all branches within git command environment and need to look at other avenues.

Original Size Of Full Git Clones

To illustrate the size difference here is the default full git clone environment when you run centmin.sh menu option 23 submenu option 1 to create /usr/local/src/centminmod

702MB in size

Code:

du -sh /usr/local/src/centminmod
702M    /usr/local/src/centminmod

size-pack = 691,401 bytes

Code:

git count-objects -v
count: 0
size: 0
in-pack: 9595
packs: 1
size-pack: 691401
prune-packable: 0
garbage: 0
size-garbage: 0

list of all branches available

Code:

git branch -a
* 123.09beta01
  master
  remotes/origin/123.06stable
  remotes/origin/123.07stable
  remotes/origin/123.08beta03
  remotes/origin/123.08beta03-el7ffmpeg-fix
  remotes/origin/123.08beta03-rtmp
  remotes/origin/123.08beta03libressl

  remotes/origin/123.09beta01-gcc
  remotes/origin/123.09beta01-gcc2
  remotes/origin/123.09beta01le
  remotes/origin/123.09beta01le2
  remotes/origin/123.09beta01le3
  remotes/origin/123.09beta01le4
  remotes/origin/HEAD -> origin/master
  remotes/origin/master

Proposed New Method For Git Clone Of Single Branch

The proposed new centmin.sh menu option 23 submenu option 1 and 3 options is to pull just the single github branch. It will be much faster to clone/pull and smaller in size. But won't have all the branches available for listing.

Single branch git clone

Code:

git clone -b 123.09beta01 --depth=1 https://github.com/centminmod/centminmod.git centminmod

Timing how much faster it's to clone = 3.666 seconds

Code:

time git clone -b 123.09beta01 --depth=1 https://github.com/centminmod/centminmod.git centminmod
Cloning into 'centminmod'...

real    0m3.666s
user    0m0.287s
sys     0m0.185s

Much smaller size 51MB vs 702MB as it only pulls download the single 123.09beta01 branch instead of all branches and history

Code:

du -sh centminmod/
51M     centminmod/

size-pack = 24737 bytes

Code:

git count-objects -v  
count: 0
size: 0
in-pack: 283
packs: 1
size-pack: 24737
prune-packable: 0
garbage: 0
size-garbage: 0

Only 123.09beta01 branch available

Code:

git branch -a
* 123.09beta01
  remotes/origin/123.09beta01

centmin.sh menu option 23 submenu option 3

With the new proposed method as you can see you can no longer list all available branches in centmin.sh menu option 23 submenu menu option 3 to switch branches.

Existing method pulls the branch list via git as you have access to all branch listing info.

So with the new proposed method, I need to find a way to display this branch listing info when a user selects centmin.sh menu option 23 submenu option 3.

Currently, I have worked on a plain curl command to grab the branch listings from github.com site itself outside of git cmd which means it's much faster.

For github.com branch listing, they have listed on site active branches so it means more relevant listing as i don't display older unused branches. The curl command ends up with following listing:

Code:

curl -s https://github.com/centminmod/centminmod/branches/active | grep -P '\/centminmod\/centminmod\/tree\/.*">' | grep -Po '(?<=href=")[^"]*(?=")' | sed 's|/centminmod/centminmod/tree/||g' | sort -u                     
123.08stable
123.09beta01
123.09beta01-gcc
123.09beta01-gcc2
123.09beta01le
123.09beta01le2
123.09beta01le3
123.09beta01le4

The gitlab back centminmod repo, doesn't list active branches separately so has a slightly different display if i order by most recently updated branches as older inactive branches are included unlike with github's active branch listing page. The curl command ends up with following listing:

Code:

curl -s https://gitlab.com/centminmod/centminmod/branches?sort=recently_updated | grep -P '\/centminmod\/centminmod\/tree\/.*">' | grep -Po '(?<=href=")[^"]*(?=")' | sed 's|/centminmod/centminmod/tree/||g' | sort -u
