Walking botocore

gistfile1.txt

Clone botocore and run `git rev-list --all > commit_list.txt` to get a chrological list of the hashes.
Then I manually installed https://github.com/nok/git-walk but had to modify it to use my list instead of generating it's own each time because it was going into a loop.
So `read_commit_ids` looks like this:

```
def read_commit_ids():
    #cmd = 'git rev-list --all'
    #log = subp.check_output(cmd.split()).strip()
    #log = [line.strip() for line in log.split('\n')]
    with open("commit_list.txt") as f:
        log = f.read().splitlines() 
    return log
```

Then create `get_count.sh` with (for counting actions):
```
#!/bin/bash
# This uses https://github.com/nok/git-walk installed manually

until [ $(git show -s --format=%H) = "463d8b7836e4db1c62c6b3bbff1a5e25dffe6f78" ]; do
  echo "`git show -s --format=%ci`,`cat botocore/data/*/*/service*.json | jq '.metadata.endpointPrefix as $service|.operations|keys[]|$service+":"+.' 2>/dev/null | sort | uniq | wc -l | sed 's/ *//'`"
  git walk prev
done
```

For counting services I used:
```
#!/bin/bash
# This uses https://github.com/nok/git-walk installed manually

until [ $(git show -s --format=%H) = "463d8b7836e4db1c62c6b3bbff1a5e25dffe6f78" ]; do
  echo "`git show -s --format=%ci`,`ls -d botocore/data/*/ | wc -l | sed 's/ *//'`"
  git walk prev
done
```
Run this and output to tmp file.  Then I opened this in Visual Code and did a search and replace on the date to get it in a format with just '2018-01-01'.

Then I created a file `max_by_month.py` with:

```
#!/usr/bin/env python

with open("counts.csv") as f:
    lines = f.read().splitlines()

dates = []
counts = []
month = ''
month_max = 0
for l in lines:
    parts = l.split(',')
    date_parts = parts[0].split('-')
    line_month = date_parts[0]+'-'+date_parts[1]
    if line_month != month:
        print('{}-01,{}'.format(month, month_max))
        month_max = 0
    month = line_month
    if month_max < parts[1]:
        month_max = parts[1]
```

Then opened in excel and created the chart.
