Turn on debugging

Problem: I want to turn on debugging to get more information about my repository and how Git is executing commands.

Possible fixes: Try the following:

  1. At the terminal or command prompt, run the following commands on your local machine before running Git commands:

    On Linux, macOS, or Unix:

    export GIT_TRACE_PACKET=1
export GIT_TRACE=1
export GIT_CURL_VERBOSE=1

    On Windows:

    set GIT_TRACE_PACKET=1
set GIT_TRACE=1
set GIT_CURL_VERBOSE=1
    Note

    Setting GIT_CURL_VERBOSE is useful for HTTPS connections only. SSH does not use the libcurl library.

  2. To get more information about your Git repository, create a shell script similar to the following, and then run the script:

    #!/bin/sh

gc_output=`script -q -c 'git gc' | grep Total`
object_count=$(echo $gc_output | awk -F ' |\(|\)' '{print $2}')
delta_count=$(echo $gc_output | awk -F ' |\(|\)' '{print $5}')

verify_pack_output=`git verify-pack -v objects/pack/pack-*.pack .git/objects/pack/pack-*.pack 2>/dev/null`
largest_object=$(echo "$verify_pack_output" | grep blob | sort -k3nr | head -n 1 | awk '{print $3/1024" KiB"}')
largest_commit=$(echo "$verify_pack_output" | grep 'tree\|commit\|tag' | sort -k3nr | head -n 1 | awk '{print $3/1024" KiB"}')
longest_delta_chain=$(echo "$verify_pack_output" | grep chain | tail -n 1 | awk -F ' |:' '{print $4}')

branch_count=`git branch -a | grep remotes/origin | grep -v HEAD | wc -l`
if [ $branch_count -eq 0 ]; then
    branch_count=`git branch -l | wc -l`
fi

echo "Size: `git count-objects -v | grep size-pack | awk '{print $2}'` KiB"
echo "Branches: $branch_count"
echo "Tags: `git show-ref --tags | wc -l`"
echo "Commits: `git rev-list --all | wc -l`"
echo "Objects: $object_count"
echo "Delta objects: $delta_count"
echo "Largest blob: $largest_object"
echo "Largest commit/tag/tree: $largest_commit"
echo "Longest delta chain: $longest_delta_chain"

  3. If these steps do not provide enough information for you to resolve the issue on your own, ask for help on the AWS CodeCommit forum. Be sure to include relevant output from these steps in your post.
