Fetch events for a given Sentry issue

sentry-fetch-issue-events

#!/usr/bin/env bash

set -euo pipefail

USAGE="Usage: $(basename "$0") ISSUE_ID

Fetches all events for an issue, page by page.

At any time you feel you've retrieved enough events, use CTRL-C to stop
fetching.

Events are sent to stdout, so recommended usage is to pipe to a file e.g.,:

  $(basename "$0") ISSUE_ID > output-file
"

if [ -z "${SENTRY_AUTH_TOKEN:-}" ]; then
  echo "\$SENTRY_AUTH_TOKEN must be set

Make a token @ https://sentry.io/settings/account/api/auth-tokens/

Scopes: event:read, project:read
" >&2
exit 1
fi

headers_file="$(mktemp)"
issue_id="${1-}"
json_arrays_file="$(mktemp)"
url="https://sentry.io/api/0/issues/${issue_id}/events/?full=true"

if [ -z "$issue_id" ]; then
  echo "$USAGE" >&2
  exit 1
fi

combine_results() {
  echo "combining..." >&2
  jq '.[]' "$json_arrays_file" | jq --slurp
}
trap combine_results EXIT

requires() {
  command -v "$1" > /dev/null || ( echo "Requires ${1}" >&2; exit 1 )
}
requires curl
requires jq

while [ "$url" ]; do
  curl "${url}" \
    -H "Authorization: Bearer $SENTRY_AUTH_TOKEN" \
    --silent --show-error --dump-header /dev/stderr \
    1>> "$json_arrays_file" \
    2> "$headers_file"
  echo "Fetched page. Will paginate until done, or ctrl-c to stop sooner" >&2
  url="$(sed -n -E 's/link:.*<(.*?)>; rel="next"; results="true".*/\1/p' < "$headers_file")"
done

To workaround a temp API issue of results always being results="false", change:

url="$(sed -n -E 's/link:.*<(.*?)>; rel="next"; results="true".*/\1/p' < "$headers_file")"

to

url="$(sed -n -E 's/link:.*<(.*?)>; rel="next"; results.*/\1/p' < "$headers_file")"
