Installing

crashstats-tools is available on PyPI. You can install it with pipx:

$ pipx install crashstats-tools

For developing crashstats-tools, clone the Git repository, create a virtual environment, and install crashstats-tools and dev dependencies with:

$ pip install -e '.[dev]'

Support

This is a project that I spent some time on because it seemed helpful to me and others. I use it regularly for Crash Stats investigations and reprocessing. However, I'm not you! If you have any problems, please write up an issue in the issue tracker and I'll get to it when I'm able.

If you use this, like it, appreciate it, or have any positive feeling, please give it a GitHub star. That helps me:

have a proxy for knowing whether it's being used
prioritize my time working on this project
have a hand-wavey list of users in case I have questions and need to ask for advice

supersearch

]]]

Usage: supersearch [OPTIONS]

  Performs a basic search on Crash Stats using the Super Search API and outputs
  the results.

  A basic search uses filters and can span multiple pages of results. A basic
  search cannot include facets, aggregations, histograms, or cardinalities. For
  those, use supersearchfacet.

  There are two ways to run this:

  First, you can specify Super Search API fields to generate the query.

  For example:

  $ supersearch --product=Firefox --num=10

  Second, you can pass in a url from a Super Search on Crash Stats. This command
  will then pull out the filter parameters. You can override those parameters
  with command line arguments.

  $ supersearch --supersearch-url='https://crash-stats.mozilla.org/search/...'

  Make sure to use single quotes when specifying values so that your shell
  doesn't expand variables or parse escape sequences.

  You can specify returned fields using the Super Search field "_columns".

  For example:

  $ supersearch --_columns=uuid --_columns=product --_columns=build_id

  Results are tab-delimited by default. You can specify other output formats
  using "--format". Tabs and newlines in output are escaped.

  For list of available fields and Super Search API documentation, see:

  https://crash-stats.mozilla.org/documentation/supersearch/

  https://crash-stats.mozilla.org/documentation/supersearch/api/

  This requires an API token in order to search and get results for protected
  data fields. Using an API token also reduces rate-limiting. Set the
  CRASHSTATS_API_TOKEN environment variable to your API token value:

  CRASHSTATS_API_TOKEN=xyz supersearch ...

  To create an API token for Crash Stats, visit:

  Remember to abide by the data access policy when using data from Crash Stats!
  The policy is specified here:

  --headers / --no-headers        whether or not to show table headers
                                  [default: no-headers]
  --format [table|tab|csv|json|markdown]

                                  no-verbose]
  --color / --no-color            whether or not to colorize output; note that
                                  color is shut off when stdout is not an
                                  interactive terminal automatically  [default:
                                  color]

Fetch 10 crash ids for Firefox:

$ supersearch --num=10 --product=Firefox

Fetch all crash reports that have libc2.30.so/E22A1E7AEF7C58504AF2C60A5AD3A7AE0 in the modules_in_stack field:

$ supersearch --modules_in_stack=libc2.30.so/E22A1E7AEF6C58504AF2C60A5AD3A7AE0

This is helpful when you need to reprocess crash reports after uploading symbols for a module that we didn't have symbols for.

Fetch all crash reports that have libgallium_dri.so in the modules_in_stack field:

$ supersearch --modules_in_stack='^libgallium_dri.so'

Fetch 57 crash ids that match a Super Search query:

$ supersearch --num=57 \
    --supersearch-url='https://crash-stats.mozilla.org/search/?release_channel=nightly&version=70.0a1&product=Firefox&_sort=-date'

Use single quotes for values so that your shell doesn't do any shell expansion.

Fetch uuid, product, version, and build_id for crash reports that have "OOM" in the signature:

$ supersearch --_columns=uuid --_columns=product --_columns=version \
    --_columns=build_id --signature='~OOM'

Note that this doesn't support Super Search aggregations--use the supersearchfacet command for that.

This lets you download raw crash, dumps, and processed crash from Crash Stats.

Fetch processed crash data for specific crash id:

$ fetch-data --no-raw --no-dumps --processed 723cacd6-1684-420e-a1c7-f04240190731

Fetch raw crash data using supersearch command to generate crash ids:

$ supersearch --product=Firefox --num=10 | \
    fetch-data --raw --no-dumps --no-processed crashdir

Reprocess an individual crash report:

$ reprocess 723cacd6-1684-420e-a1c7-f04240190731

Reprocess crash reports based on a supersearch:

$ supersearch --num=5 | reprocess

Note

The reprocess command requires that you set CRASHSTATS_API_TOKEN in your environment with an API token that has the "Reprocess Crashes" permission.

Note

If you intend to reprocess more than 10,000 crash reports, please tell us first.

API token

For supersearch and fetch-data, you need to use a API token to:

download data containing personally identifiable information
download security sensitive data
get out from the shadow of extreme API use rate limiting

You need an API token for reprocess--it doesn't work without one.

If you have access, you can generate an API token here:

https://crash-stats.mozilla.org/api/tokens/

Once you have acquired one, set the CRASHSTATS_API_TOKEN environment variable when using crashstats-tools commands.

Remember to abide by the data access policy when using data from Crash Stats! The policy is specified here:

https://crash-stats.mozilla.org/documentation/memory_dump_access/

Use cases

These tools are helpful when downloading data for analysis as well as downloading data to test other tools with.

Example 1

I want to collect a bunch of crash report data to look at possible values of an annotation in Firefox crash reports that's not available in Super Search, yet.

Since I'm looking just at annotations, all I need is the raw crash.

I would do something like this:

$ mkdir crashdata
$ supersearch --product=Firefox --num=1000 | \
    fetch-data --raw --no-dumps --no-processed crashdata

Then I can use jq or whatever to look at the crash report data in crashdata/raw_crash/.

Example 2

I want to test out a new JIT analysis tool that works on minidump files.

I would write a script like this:

#!/bin/bash

CRASHSTATS_API_TOKEN=foo
DATADIR=./crashdata
CRASHIDS=$(supersearch --product=Firefox --num=1000)

mkdir -p "${DATADIR}"

for crashid in ${CRASHIDS}
do
    echo "crashid ${crashid}"
    fetch-data --raw --dumps --no-processed "${DATADIR}" "${crashid}"

    # Not all crash reports have dumps--we only want to run analysis
    # on the ones that do.
    if [[ -e "crashdata/dump/${crashid}" ]]
    then
        echo "analyze dump ${crashid}..."
        # run my tool on the dump
    fi
done

Example 3

I want to get a list of crash ids for today (2019-07-30) where DOMFissionEnabled exists in the crash report.

I would do this:

$ supersearch --date=">=2019-07-30" --date='<2019-07-31' \
    --dom_fission_enabled='!__null__'

Example 4

I want to see number of crash reports for the last 14 days broken down by day and by product where DOMFissionEnabled exists in the crash report.

I would do this:

$ supersearchfacet --period=daily --format=markdown --relative-range=14d \
    --dom_fission_enabled='!__null__' --_facets=product

Library

Further, this provides a library interface to some Crash Stats API endpoints:

crashstats_tools.libcrashstats

get_crash_annotations(crash_id, api_token=None, host=DEFAULT_HOST)

Fetches crash annotations for a given crash report.

If you don't provide an API token, then it only returns crash annotations that are marked public.

get_dump(crash_id, dump_name, api_token, host=DEFAULT_HOST)

Fetches dumps, memory reports, and other crash report binaries for given crash id.

This requires an api token.

get_processed_crash(crash_id, api_token=None, host=DEFAULT_HOST)

Fetches the processed crash for given crash id.

supersearch(params, num_results, host=DEFAULT_HOST, api_token=None, logger=None)

Performs a super search and returns generator of result hits.

This doesn't return facet, aggregation, cardinality, or histogram data. If you want that, use supersearch_facet.

supersearch_facet(params, api_token=None, host=DEFAULT_HOST, logger=None)

Performs a super search and returns facet data

https://github.com/mozilla/libmozdata

Python library which has a Supersearch class for performing queries and a ProcessedCrash class for fetching processed crash data.

https://github.com/mozilla-services/socorro

Socorro (the code base for Crash Stats) has a Docker-based local dev environment which includes a series of commands for manipulating data.
