# Common Tools
|
|
|
|
This directory contains mostly tools that can manipulate definitions in [defs/](../defs).
|
|
|
|
Tools are written with [Click](http://click.pocoo.org/6/), so you always get a help text
|
|
if you use the `--help` option.
|
|
|
|
All tools require Python 3.6 or higher and a bunch of dependencies, listed in `requirements.txt`.
|
|
You can install them all with `pip3 install -r requirements.txt`.
|
|
|
|
## Tools overview
|
|
|
|
### `cointool.py`
|
|
|
|
This is a general-purpose tool to examine coin definitions. Currently it implements
|
|
the following commands:
|
|
|
|
* **`render`**: generate code based on a [Mako](http://docs.makotemplates.org/en/latest/index.html)
|
|
template. By default, `cointool.py render foo.bar.mako` will put its result into
|
|
file `foo.bar` in the same directory. See [usage in `trezor-core`](https://github.com/trezor/trezor-core/commit/348b99b8dc5bcfc4ab85e1e7faad3fb4ef3e8763).
|
|
* **`check`**: check validity of json definitions and associated data. Used in CI.
|
|
* **`dump`**: dump coin information, including support status, in JSON format. Various
|
|
filtering options are available, check help for details.
|
|
|
|
Use `cointool.py command --help` to get more information on each command.
|
|
|
|
### `support.py`
|
|
|
|
Used to query and manage info in `support.json`. This mainly supports the release flow.
|
|
|
|
The following commands are available:
|
|
|
|
* **`check`**: check validity of json data. Used in CI.
|
|
* **`fix`**: prune keys without associated coins.
|
|
* **`show`**: keyword-search for a coin and show its support status for each device.
|
|
* **`set`**: set support data.
|
|
* **`release`**: perform the [release workflow](#release-workflow).
|
|
|
|
Use `support.py command --help` to get more information on each command.
|
|
|
|
### `coin_info.py`
|
|
|
|
In case where code generation with `cointool.py render` is impractical or not sufficient,
|
|
you can query the data directly through Python. Short usage example:
|
|
|
|
```python
|
|
import coin_info
|
|
|
|
defs = coin_info.coin_info()
|
|
list_of_all_coins = defs.as_list()
|
|
dict_by_coin_key = defs.as_dict()
|
|
|
|
for token in defs.erc20:
|
|
print(token["key"], token["name"], token["shortcut"])
|
|
|
|
support_info = coin_info.support_info(defs.misc)
|
|
for key, support in support_info.values():
|
|
t2_support = support["T2T1"]
|
|
coin_name = dict_by_coin_key[key]
|
|
if t2_support:
|
|
print(coin_name, "is supported since version", t2_support)
|
|
else:
|
|
print(coin_name, "is not supported")
|
|
```
|
|
|
|
See docstrings for the most important functions: `coin_info()` and `support_info()`.
|
|
|
|
The file `coindef.py` is a protobuf definition for passing coin data to Trezor
|
|
from the outside.
|
|
|
|
### `marketcap.py`
|
|
|
|
Module for obtaining market cap and price data used by `maxfee.py`.
|
|
|
|
### `maxfee.py`
|
|
|
|
Updates the `maxfee_kb` coin property based on a specified maximum per-transaction fee. The command
|
|
fetches current price data from https://coinmarketcap.com/ to convert from fiat-denominated maximum
|
|
fee.
|
|
|
|
# Release Workflow
|
|
|
|
This entails collecting information on coins whose support status is unknown and
|
|
bumping timestamp of external definitions <??? TODO>.
|
|
|
|
## Maintaining Support Status
|
|
|
|
When a new coin definition is added, its support status is _unknown_. It is excluded
|
|
from code generation by default. If you want to include a coin in a firmware build,
|
|
you need to switch it to supported in a particular version first. You can set multiple
|
|
support statuses at the same time:
|
|
|
|
```
|
|
$ ./support.py show Ontology
|
|
misc:ONT - Ontology (ONT)
|
|
* connect : NO
|
|
* T1B1 : support info missing
|
|
* T2T1 : support info missing
|
|
* suite : NO
|
|
|
|
$ ./support.py set misc:ONT T1B1=no -r "not planned on T1" T2T1=2.4.7
|
|
misc:ONT - Ontology (ONT)
|
|
* connect : NO
|
|
* T1B1 : NO (reason: not planned on T1)
|
|
* T2T1 : 2.4.7
|
|
* suite : NO
|
|
```
|
|
|
|
Afterwards, review and commit changes to `defs/support.json`, and update the `trezor-common`
|
|
submodule in your target firmware.
|
|
|
|
## Releasing a new firmware
|
|
|
|
#### **Step 1:** run the release script
|
|
|
|
```sh
|
|
./tools/release.sh
|
|
```
|
|
|
|
Coins in state _unknown_, i.e., coins that are known in the definitions but not listed
|
|
in support files, will be interactively added one by one. To avoid that, run `support.py
|
|
release -y` separately.
|
|
|
|
#### **Step 2:** review and commit your changes
|
|
|
|
Use `git diff` to review changes made, commit and push.
