|
| Trying to configure app-portage/fetchcommandwrapper. How do I change the default configuration? /usr/share/fetchcommandwrapper/make.conf isn't very helpful, and I want to add more than 5 download threads. Anyone know how? |

That option is set in the installed file, which for me is located at:
/usr/lib/python3.12/site-packages/fetchcommandwrapper/__main__.py
You could modify this file directly and change the line:
to something else. For example:
You would have to do this every time you install the file or update/rebuild the package through portage.
For a more persistent solution, you might be able to write a patch that will modify the sources:
https://wiki.gentoo.org/wiki//etc/portage/patches
Sam would encourage you to use that method.
However, I am not good with patches. If I am simply modifying one line or string in a source file of a downloaded package, I usually, as a personal preference, use the portage bashrc file, /etc/portage/bashrc:
https://wiki.gentoo.org/wiki//etc/portage/bashrc
For this particular package you would need to set up your own local repo if you have not already:
https://wiki.gentoo.org/wiki/Creating_an_ebuild_repository
I kept the defaults and mine is located at:
/var/db/repos/localrepo
You will need root privileges.
Create the directory:
| Code: | | mkdir -p /var/db/repos/localrepo/app-portage/fetchcommandwrapper/files |
Copy the files from the Gentoo repo to the local repo:
| Code: | cp -rv /var/db/repos/gentoo/app-portage/fetchcommandwrapper/* /var/db/repos/localrepo/app-portage/fetchcommandwrapper
|
Go to the files directory you just created within:
| Code: | | cd /var/db/repos/localrepo/app-portage/fetchcommandwrapper/files |
Use your preferred editor (I use nano) to create a bash script that will use sed to change the MAX_STREAMS in the portage downloaded source file from 5 to the desired value, I am using 10 as an example:
| Code: | | nano MAX_STREAMS.sh |
Insert the following text (note the double underscores in the filename):
| Code: | #!/bin/bash
sed -i "s/MAX_STREAMS = 5/MAX_STREAMS = 10/" /var/tmp/portage/app-portage/fetchcommandwrapper*/work/fetchcommandwrapper*/fetchcommandwrapper/__main__.py |
Hit ctrl+x to save.
Change the permissions to executable:
| Code: | | chmod +x MAX_STREAMS.sh |
Change to parent directory:
Build the manifest for the ebuild file(s) in this directory, which in my case was:
| Code: | | ebuild fetchcommandwrapper-0.8.4-r5.ebuild digest |
Next you would create the portage hook. If it does not exist you can create the file:
/etc/portage/bashrc
Insert the following text (edited to your preferences, this is what works for me):
| Code: | #!/bin/bash
###Increase MAX_STREAMS for app-portage/fetchcommandwrapper
if [ "${CATEGORY}/${PN}" == "app-portage/fetchcommandwrapper" ] && [ "${EBUILD_PHASE}" == "configure" ] ; then
echo -e " \e[31;1m*** The fetchcommandwrapper sources will be modified.\e[0m"
bash -c '/var/db/repos/localrepo/app-portage/fetchcommandwrapper/files/MAX_STREAMS.sh'
echo -e " \e[31;1m*** The fetchcommandwrapper sources were modified.\e[0m"
fi
|
This will output red coded text that is easy to identify in the portage output when installing fetchcommandwapper. If there are any errors you will see them printed between the two lines of red text:
| Code: |
*** The fetchcommandwrapper sources will be modified.
bash: line 1: /var/db/repos/localrepo/app-portage/fetchcommandwrapper/files/MAX_STREAMS.sh: Permission denied
*** The fetchcommandwrapper sources were modified.
|
The above would occur if you forgot to make the bash script executable for example.
You may need to first source the portage bashrc file, but I am not certain of that to be honest:
| Code: | | source /etc/portage/bashrc |
You can check after installation if these changes were successful and troubleshoot accordingly by reviewing the contents of the file:
/usr/lib/python3.12/site-packages/fetchcommandwrapper/__main__.py
If all went well it should say:
There may, however, be a reason that the developer set the max streams to 5, so be prepared to monitor things for unexpected consequences. The max streams may be an arbitrary number or it may have been considered the optimum setting after thorough testing.

I did first state that it is possible to create a patch. I will add that link to my response in the appropriate place. |
