Joel Purra: Developer and more


har-portent

Using har-heedless to download and har-dulcify to analyze web pages in aggregate.

  • Downloads the front web page of all domains in a dataset.
    • Input is a text file with one domain name per line.
    • Downloads n domains in parallel.
      • Tested with over 100 parallel requests on a single of moderate speed and memory. YMMV.
      • Machine load heavily depends on the complexity and response rate of the average domain in the dataset.
    • Shows progress as well as expected time to finish downloads.
    • Download domains with different prefixes as separate dataset variations.
      • Default prefixes:
        • http://
        • https://
        • http://www.
        • https://www.
    • Retries failed domains twice to reduce effect of any intermittent problems.
      • Increases domain timeouts for failed domains.
    • Saves screenshots of all webpages.
  • Runs an analysis on each dataset variation.
    • Outputs JSON files for analysis.
    • Prepared for aggregate dataset analysis to output tables (TSV/CSV), which in turn are prepared for graph creation.

Directory structure

# $PWD/$(date -u +%F)/$(basename "$domainlist")-$prefix/hars

Usage

# Create directory structure and download all domains in domains.txt with a single prefix/variation.
# ./src/domains/download-and-analyze-https-www-combos.sh <prefix> <parallelism> <domainlists>
./src/domains/download-and-analyze-https-www-combos.sh 'https://www.' 10 many-domains.txt more-domains.txt 100k-se-domains.txt

# Create directory structure and download all domains in domains.txt with all four variations.
# ./src/domains/download-and-analyze-https-www-combos.sh <parallelism> <domainlists>
./src/domains/download-and-analyze-https-www-combos.sh 10 many-domains.txt more-domains.txt 100k-se-domains.txt

Other usage:

# Re-run question step in each dataset.
~/path/to/har-dulcify/src/util/dataset-foreach.sh $(find . -mindepth 2 -maxdepth 2 -type d) -- echo "--- Entering {} ---" '&&' ~/path/to/har-dulcify/src/one-shot/questions.sh

# Re-run aggregate and question step in each dataset.
~/path/to/har-dulcify/src/util/dataset-foreach.sh $(find . -mindepth 2 -maxdepth 2 -type d) -- echo "--- Entering {} ---" '&&' ~/path/to/har-dulcify/src/one-shot/aggregate.sh '&&' ~/path/to/har-dulcify/src/one-shot/questions.sh

# Copy selected files from each dataset.
OUTPUT="$HOME/path/to/output/analysis/$(date -u +%F)" ~/path/to/har-dulcify/src/util/dataset-query.sh $(find . -mindepth 2 -maxdepth 2 -type d) -- echo "--- Entering {} ---" '&&' 'T="$OUTPUT/$(basename "{}")"' '&&' echo '$T' '&&' mkdir -p '$T/' '&&' cp aggregate.disconnect.categories.organizations.json aggregates.analysis.json '*.log' 'failed*' google-gtm-ga-dc.aggregate.json origin-redirects.aggregate.json ratio-buckets.aggregate.json prepared.disconnect.services.analysis.json '$T/'

Example output

Downloading two domains, one of which doesn’t have HTTPS.

Original purpose

Built as a component in Joel Purra’s master’s thesis research, where downloading lots of front pages in the .se top level domain zone was required to analyze their content and use of internal/external resources.
