Bash auto update script

Continuing the challenge from yesterday, I’m investigating why the script:

git fetch origin
reslog=$(git log HEAD..origin/master --oneline)
if [[ "${reslog}" != "" ]] ; then

Doesn’t pick up on the available update. When executed manually in the src directory, it produces the following result:

dspacesitechecker@atmire3:~/src$ git log HEAD..origin/master --oneline
142b138 Adding Google Scholar reference to HEAD TITLE

Some of the things I learned included

• the square braces operator is the equal to the command test
• with $? you can get the result of the previous command

What finally worked to positively evaluate the string comparison statement was the following:

reslog=$([ "`git log --pretty=%H ...refs/heads/master^ | head -n 1`" = "`git ls-remote origin -h refs/heads/master |cut -f1`" ] && echo "up to date" || echo "not up to date")
if [ "$reslog" = "*not up to date*" ] ; then

Assuming that I had something going on with leading or trailing spaces. I could also look into removing these leading or trailing spaces cfr how do I trim leading and trailing whitespace from each line of some output?, but did not have the time to do this yet.

But frustratingly enough, the update script still doesn’t evaluate and update correctly. To be continued tomorrow.

Day 31 Plan

• Fix the execution of the update script.

Future days - Analyzer.atmire.com work

• Change String based implementation of error message handling with types and objects, according to Antoine Snyers recent Atmire DevTalk.
• Change string based implementation of the different browse styles to an object, according to Antoine Snyers recent Atmire DevTalk
• Optimize my hideous methods for getItemcount and getRepoCount.
• Re-test the check if we return the right repository to a user who tries to add a new one
• Updating a repository: touch/change the base URL or not?
• Batch ingest: switch to newer add repository methods.
• WCAG testing against the start page to ensure it’s accessible for people who rely on assistive tools.
• Transition from plain CSS to SASS to make it prettier and learn about SASS at the same time
• Instead of the 5 minute cron job, look into a gitlab webhook that executes the update script on prod whever something is committed to master.

Future Days - other ideas

1. Switch to a different project: start working on DSpace 7 Angular
2. Setup IDEA so I can start editing these blogposts from there, instead of in a text editor
3. Developer productivity: Get my IntelliJ IDEA Shortcuts in order (CMD+1, CMD+/, …)

Sustainability - Raising the stakes - Looking for sponsors

I have raised the stakes by

• giving €100 to Charity:Water for every day I miss.
• asking people to sponsor me and to give an amount to a charity for each day I successfully complete

This way, every day would be a win. These are the rules that I’ll apply:

1. I can anticipate or fix a lost day by doing an hour extra the day before, or an hour extra the day after. In theory this means I can maximally compensate a streak of 2 missed days.
2. Goal is to have a steady frequency, so I can’t just do 8h on a sunday to get myself off the hook for the next 7 days.
3. Sponsor commitments are fully voluntarily: any sponsor can back out at any time.
4. My commitment is fully voluntarily: if I want to change the rules or back out, I can at any time.

This month, these are already days that will be very tough:

• Sep 14,15,16,17 - Abroad for a wedding
• Sep 27,28 - Supernova conference Antwerp

So that’s already a lot of exposure to potentially missed days.

I will raise the stakes this way and gather money for Charity:Water. Let me know if you want to sponsor me and for how much per completed day in September. September 1st is the first successfully completed day.

September tracking

Will only log the failed days here. No failed days so far.

Thanks to the following sponsors!

1. Jan & Hilde: €2 per successful day (Yes, these are my parents)
