Store GitHub data gzipped at rest (#751) Summary: We store the relational view in `view.json.gz` instead of `view.json`, taking advantage of the isomorphic `pako` library for gzip encoding and decoding. Sample space savings (note that post bodies are included; i.e., #747 has not been applied): SAVE OLD (B) NEW (B) REPO 89.7% 25326 2617 sourcecred/example-github 82.9% 3257576 555948 sourcecred/sourcecred 85.2% 11287621 1665884 ipfs/js-ipfs 88.0% 20953425 2520358 gitcoinco/web 84.4% 38196825 5951459 ipfs/go-ipfs 84.9% 205770642 31101452 tensorflow/tensorflow <details> <summary>Script to generate space savings output</summary> ```shell savings() { printf '% 7s % 11s % 11s %s\n' 'SAVE' 'OLD (B)' 'NEW (B)' 'REPO' for repo; do file="${SOURCECRED_DIRECTORY}/data/${repo}/github/view.json.gz" if !

Test Plan: Comparing the raw old version with the decompressed new version shows that they are identical: ``` $ <~/tmp/sourcecred/data/sourcecred/example-github/github/view.json \ > shasum -a 256 - 63853b9d3f918274aafacf5198787e18185a61b9c95faf640a1e61f5d11fa19f - $ <~/tmp/sourcecred/data/sourcecred/example-github/github/view.json.gz \ > gzip -dc | shasum -a 256 63853b9d3f918274aafacf5198787e18185a61b9c95faf640a1e61f5d11fa19f - ``` Additionally, `yarn test --full` passes, and `yarn start` still loads data and runs PageRank properly. wchargin-branch: gzip-relational-view

Retry GitHub queries with exponential backoff (#699) Summary: This patch adds independent exponential backoff to each individual GitHub GraphQL query. We remove the fixed `GITHUB_DELAY_MS` delay before each query in favor of this solution, which requires no additional configuration (thus resolving a TODO in the process). We use the NPM module `retry` with its default settings: namely, a maximum of 10 retries with factor-2 backoff starting at 1000ms. Empirically, it seems very unlikely that we should require much more than 2 retries for a query. (See Test Plan for more details.) This is both a short-term unblocker and a good kind of thing to have in the long term. Test Plan: Note that `yarn test --full` passes, including `fetchGithubRepoTest.sh`. Consider manual testing as follows. Add `console.info` statements in `retryGithubFetch`, then load a large repository like TensorFlow, and observe the output: ```shell $ node bin/sourcecred.js load --plugin github tensorflow/tensorflow 2>&1 | ts -s '%.s' 0.252566 Fetching repo... 0.258422 Trying... 5.203014 Trying... [snip] 1244.521197 Trying... 1254.848044 Will retry (n=1)... 1260.893334 Trying... 1271.547368 Trying... 1282.094735 Will retry (n=1)... 1283.349192 Will retry (n=2)... 1289.188728 Trying...

Add `sharness` for shell-based testing (#597) Summary: We will shortly want to perform testing of shell scripts; it makes the most sense to do so via the shell. We could roll our own testing framework, but it makes more sense to use an existing one. By choosing Sharness, we’re in good company: `go-ipfs` and `go-multihash` use it as well, and it’s derived from Git’s testing library. I like it a lot. For now, we need a dummy test file; our test runner will fail if there are no tests to run. As soon as we have a real test, we can remove this. This commit was generated by following the “per-project installation” instructions at https://github.com/chriscool/sharness, and by additionally including that repository’s `COPYING` file as `SHARNESS_LICENSE`, with a header prepended. I considered instead adding Sharness as a submodule, which is supported and has clear advantages (e.g., you can update the thing), but opted to avoid the complexity of submodules for now. Test Plan: Create the following tests in the `sharness` directory: ```shell $ cat sharness/good.t #!/bin/sh test_description='demo of passing tests' . ./sharness.sh test_expect_success "look at me go" true test_expect_success EXPENSIVE "this may take a while" 'sleep 2' test_done # vim: ft=sh $ cat sharness/bad.t #!/bin/sh test_description='demo of failing tests' . ./sharness.sh test_expect_success "I don't feel so good" false test_done # vim: ft=sh ``` Note that `yarn sharness` and `yarn test` fail appropriately. Note that `yarn sharness-full` fails appropriately after taking two extra seconds, and `yarn test --full` runs the latter. Each failure message should print the name of the failing test case, not just the suite name, and should indicate that the passing tests passed. Then, remove `sharness/bad.t`, and note that the above commands all pass, with the `--full` variants still taking longer. Finally, remove `sharness/good.t`, and note that the above commands all pass (and all pass quickly). wchargin-branch: add-sharness
