# Code of Conduct - gege-jdr-backend
## Our Pledge
In the interest of fostering an open and welcoming environment, we as
contributors and maintainers pledge to make participation in our
project and our community a harassment-free experience for everyone,
regardless of age, body size, disability, ethnicity, sex
characteristics, gender identity and expression, level of experience,
education, socio-economic status, nationality, personal appearance,
race, religion, or sexual identity and orientation.
## Our Standards
Examples of behavior that contributes to a positive environment for
our community include:
* Demonstrating empathy and kindness toward other people
* Being respectful of differing opinions, viewpoints, and experiences
* Giving and gracefully accepting constructive feedback
* Accepting responsibility and apologizing to those affected by our
mistakes, and learning from the experience
* Focusing on what is best not just for us as individuals, but for the
overall community
Examples of unacceptable behavior include:
* The use of sexualized language or imagery, and sexual attention or
advances
* Trolling, insulting or derogatory comments, and personal or
political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or email
address, without their explicit permission
* Other conduct which could reasonably be considered inappropriate in
a professional setting
## Our Responsibilities
Project maintainers are responsible for clarifying and enforcing our
standards of acceptable behavior and will take appropriate and fair
corrective action in response to any behavior that they deem
inappropriate, threatening, offensive, or harmful.
Project maintainers have the right and responsibility to remove, edit,
or reject comments, commits, code, wiki edits, issues, and other
contributions that are not aligned to this Code of Conduct, and will
communicate reasons for moderation decisions when appropriate.
## Scope
This Code of Conduct applies within all community spaces, and also
applies when an individual is officially representing the community in
public spaces. Examples of representing our community include using an
official e-mail address, posting via an official social media account,
or acting as an appointed representative at an online or offline
event.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior
may be reported to the community leaders responsible for enforcement
at <phundrak>. All complaints will be reviewed and investigated
promptly and fairly.
All community leaders are obligated to respect the privacy and
security of the reporter of any incident.
## Enforcement Guidelines
Community leaders will follow these Community Impact Guidelines in
determining the consequences for any action they deem in violation of
this Code of Conduct:
### 1. Correction
**Community Impact**: Use of inappropriate language or other behavior
deemed unprofessional or unwelcome in the community.
**Consequence**: A private, written warning from community leaders,
providing clarity around the nature of the violation and an
explanation of why the behavior was inappropriate. A public apology
may be requested.
### 2. Warning
**Community Impact**: A violation through a single incident or series
of actions.
**Consequence**: A warning with consequences for continued behavior.
No interaction with the people involved, including unsolicited
interaction with those enforcing the Code of Conduct, for a specified
period of time. This includes avoiding interactions in community
spaces as well as external channels like social media. Violating these
terms may lead to a temporary or permanent ban.
### 3. Temporary Ban
**Community Impact**: A serious violation of community standards,
including sustained inappropriate behavior.
**Consequence**: A temporary ban from any sort of interaction or
public communication with the community for a specified period of
time. No public or private interaction with the people involved,
including unsolicited interaction with those enforcing the Code of
Conduct, is allowed during this period. Violating these terms may lead
to a permanent ban.
### 4. Permanent Ban
**Community Impact**: Demonstrating a pattern of violation of
community standards, including sustained inappropriate behavior,
harassment of an individual, or aggression toward or disparagement of
classes of individuals.
**Consequence**: A permanent ban from any sort of public interaction
within the community.

## Code of Conduct
This project and everyone participating in it is governed by the
[gege-jdr-backend Code of Conduct](CODE_OF_CONDUCT.md). By participating,
you are expected to uphold this code. Please report unacceptable
behavior to <phundrak>.
## I Have a Question
> If you want to ask a question, we assume that you have read the
> available [Documentation](/phundrak/gege-jdr-backend/wiki).
Before you ask a question, it is best to search for existing
[Issues](/phundrak/gege-jdr-backend/issues) that might help you. In case you have
found a suitable issue and still need clarification, you can write
your question in this issue. It is also advisable to search the
internet for answers first.
If you then still feel the need to ask a question and need
clarification, we recommend the following:
- Open an [Issue](/phundrak/gege-jdr-backend/issues/new).
- Provide as much context as you can about what you're running into.
- Provide project and platform versions (cargo, rustc, etc), depending
on what seems relevant.
We will then take care of the issue as soon as possible.
## I Want To Contribute
> ### Legal Notice <!-- omit in toc -->
> When contributing to this project, you must agree that you have
> authored 100% of the content, that you have the necessary rights to
> the content and that the content you contribute may be provided
> under the project license.
### Reporting Bugs
<!-- omit in toc -->
#### Before Submitting a Bug Report
A good bug report shouldn't leave others needing to chase you up for
more information. Therefore, we ask you to investigate carefully,
collect information and describe the issue in detail in your report.
Please complete the following steps in advance to help us fix any
potential bug as fast as possible.
- Make sure that you are using the latest version.
- Determine if your bug is really a bug and not an error on your side
e.g. using incompatible environment components/versions (Make sure
that you have read the [documentation](/phundrak/gege-jdr-backend/wiki). If you
are looking for support, you might want to check [this
section](#i-have-a-question)).
- To see if other users have experienced (and potentially already
solved) the same issue you are having, check if there is not already
a bug report existing for your bug or error in the [bug
tracker](/phundrak/gege-jdr-backendissues?q=label%3Abug).
- Also make sure to search the internet (including Stack Overflow) to
see if users outside of the PhundrakLabs community have discussed
the issue.
- Collect information about the bug:
- Stack trace (Traceback)
- OS, Platform and Version (Windows, Linux, macOS, x86, ARM)
- Version of the interpreter, compiler, SDK, runtime environment,
package manager, depending on what seems relevant.
- Possibly your input and the output
- Can you reliably reproduce the issue? And can you also reproduce
it with older versions?
<!-- omit in toc -->
#### How Do I Submit a Good Bug Report?
> You must never report security related issues, vulnerabilities or
> bugs including sensitive information to the issue tracker, or
> elsewhere in public. Instead sensitive bugs must be sent by email to
> <phundrak>.
<!-- You may add a PGP key to allow the messages to be sent encrypted as well. -->
We use PhundrakLabs issues to track bugs and errors. If you run into
an issue with the project:
- Open an [Issue](/phundrak/gege-jdr-backend/issues/new). (Since we can't be sure at
this point whether it is a bug or not, we ask you not to talk about
a bug yet and not to label the issue.)
- Explain the behavior you would expect and the actual behavior.
- Please provide as much context as possible and describe the
*reproduction steps* that someone else can follow to recreate the
issue on their own. This usually includes your code. For good bug
reports you should isolate the problem and create a reduced test
case.
- Provide the information you collected in the previous section.
Once it's filed:
- The project team will label the issue accordingly.
- A team member will try to reproduce the issue with your provided
steps. If there are no reproduction steps or no obvious way to
reproduce the issue, the team will ask you for those steps and mark
the issue as `Status/Need More Info`. Bugs with the `Status/Need
More Info` tag will not be addressed until they are reproduced.
- If the team is able to reproduce the issue, it will be marked
`Reviewed/Confirmed`, as well as possibly other tags (such as
`Priority/Medium`), and the issue will be left to be [implemented by
someone](#your-first-code-contribution).
<!-- You might want to create an issue template for bugs and errors that can be used as a guide and that defines the structure of the information to be included. If you do so, reference it here in the description. -->
### Suggesting Enhancements
This section guides you through submitting an enhancement suggestion for gege-jdr-backend, **including completely new features and minor improvements to existing functionality**. Following these guidelines will help maintainers and the community to understand your suggestion and find related suggestions.
<!-- omit in toc -->
#### Before Submitting an Enhancement
- Make sure that you are using the latest version.
- Read the [documentation](/phundrak/gege-jdr-backend/wiki) carefully and find out
if the functionality is already covered, maybe by an individual
configuration.
- Perform a [search](/phundrak/gege-jdr-backend/issues) to see if the enhancement
has already been suggested. If it has, add a comment to the existing
issue instead of opening a new one.
- Find out whether your idea fits with the scope and aims of the
project. It's up to you to make a strong case to convince the
project's developers of the merits of this feature. Keep in mind
that we want features that will be useful to the majority of our
users and not just a small subset. If you're just targeting a
minority of users, consider writing an add-on/plugin library.
<!-- omit in toc -->
#### How Do I Submit a Good Enhancement Suggestion?
Enhancement suggestions are tracked as [Gitea
issues](/phundrak/gege-jdr-backend/issues).
- Use a **clear and descriptive title** for the issue to identify the
suggestion.
- Provide a **step-by-step description of the suggested enhancement**
in as many details as possible.
- **Describe the current behavior** and **explain which behavior you
expected to see instead** and why. At this point you can also tell
which alternatives do not work for you.
- **Explain why this enhancement would be useful** to most
gege-jdr-backend users. You may also want to point out the other
projects that solved it better and which could serve as inspiration.
<!-- You might want to create an issue template for enhancement suggestions that can be used as a guide and that defines the structure of the information to be included. If you do so, reference it here in the description. -->
### Your First Code Contribution
#### Setting Up Your Development Environment
Code contributions are most welcome! To contribute to the project, you
will need to the README and install the
[prerequisites](/phundrak/gege-jdr-backend#prerequisites) and [setup your
development environment](/phundrak/gege-jdr-backend#installing).
You can use the IDE of your choice, popular options for Rust projects
are [VSCode](https://code.visualstudio.com/) or
[RustRover](https://www.jetbrains.com/rust/), but plenty of other code
editors are available such as:
- Emacs (we recommend [rustic](https://github.com/rustic-rs/rustic)
over [rust-mode](https://github.com/rust-lang/rust-mode)
- [Vim/NeoVim](https://github.com/rust-lang/rust.vim)
- [Sublime Text](https://github.com/rust-lang/rust-enhanced)
- [Helix](https://rust-analyzer.github.io/manual.html#helix)
- [Visual Studio](https://rust-analyzer.github.io/manual.html#visual-studio-2022)
- [Eclipse](https://projects.eclipse.org/projects/tools.corrosion)
- And plenty other text editors!
Depending on your choice, you may need to install an LSP server and an
LSP client on your text editor, such as with Emacs and Vim/NeoVim.
#### Where Should You Start?
If you want to participate to gege-jdr-backend, but youre not sure what
to do, take a look at the [opened issues](/phundrak/gege-jdr-backend/issues). You
way find issues with the `help wanted` tag where you could weigh in
for the resolution of the issue or for decision-making. You may also
find issues tagged as `good first issue` which should be relatively
approachable for first time contributors.
#### Writing Your First Code Contribution
Take your time when reading the code. The existing documentation can
help you better understand how the project is built and how the code
behaves. If you still have some questions, dont hesitate to reach out
to maintainers.
When you start writing your code, only modify what needs to be
modified. Each contribution should do one thing and one thing only. Do
not, for instance, refactor some code that is unrelated to the main
topic of your contribution.
Check often the output of clippy by running `just lint`, and check if
existing tests still pass with `just test`. Ideally, start by writing
new tests that describe the intended behaviour of your contribution
with functions that will purposefully fail these tests, then iterate
over these functions until they finally pass all tests.
Check also that your code is properly formatted with
`just format-check`. You can format it automatically with
`just format`.
Finally, check if the code coverage of gege-jdr-backend. Ideally, try to
stay within the initial percentage of code coverage of the project,
and try to stay above 75% of code coverage. If it drops below 60%,
your contribution will be rejected automatically until you add more
test covering more code.
For writing tests, dont hesitate to take a look at existing tests.
You can also read on how to write tests with SQLx [in their
documentation](https://docs.rs/sqlx/latest/sqlx/attr.test.html), as
well as some examples of poem tests in the [documentation of its
`test` module](https://docs.rs/poem/latest/poem/test/index.html).
### Improving the Documentation
To improve the documentation of gege-jdr-backend, you have two choices:
- Improve the [wiki](/phundrak/gege-jdr-backend/wiki) of the project with
high-level, functional documentation
- Improve the code documentation by adding some
[rustdoc](https://doc.rust-lang.org/rustdoc/how-to-write-documentation.html)
within the code. You can also take the opportunity to add new tests
through code examples in the rustdock; who knows, maybe you will
discover a bug writing these tests, which will help improve the code
itself!
## New Pull Requests
### Commit Messages
When creating a new commit, try to follow as closely as possible the
[Conventional Commits 1.0.0](https://www.conventionalcommits.org/)
standard. Each line should not exceed 72 characters in length. Commits
shall also be written in the present tense. Use the imperative mood as
much as possible when explaining what this commit does.
> Instead of *Fixed #42* or *Fixes #42*, write *Fix #42*
**DO NOT** increase the project version yourself. This will be up for
the maintainers to do so.
### Creating the Pull Request
Submit your pull requests to the `develop` branch. Pull requests to
other branches will be refused, unless there is a very specific reason
to do so explained in the pull request.
Note: *PR* means *Pull Request*.
**All PRs** must:
- Branch from `develop`
- Target the `develop` branch, unless specific cases. Maintainers are
the only contributors that can create a PR targeting `main`
- Live on their own branch, prefixed by `feature/` or `fix/` (other
prefixes can be accepted in specific cases) with the name of the
feature or the issue fixed in `kebab-case`
- Be rebased on `develop` if the PR is no longer up to date
- Pass the CI pipeline (a failed CI pipeline will prevent any merge)
PRs coming from a `main`, `master`, `develop`, `release/`, `hotfix/`,
or `support/` branch will be rejected. PRs not up to date with
`develop` will not be merged.
**Simple PRs** shall:
- Have only one topic
- Have only one commit
- Have all their commits squashed into one if it contains several commits
If you open a PR whose scope are multiple topics, it will be rejected.
Open as many PRs as necessary, one for each topic.
**Complex PRs** shall:
- squash uninteresting commits (fixes to earlier commits, typos,
syntax, etc…) together
- keep the major steps into individual commits

software and other kinds of works, specifically designed to ensure
cooperation with the community in the case of network server software.
The licenses for most software and other practical works are designed
to take away your freedom to share and change the works. By contrast,
our General Public Licenses are intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains
free software for all its users.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
them if you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of it in new
free programs, and that you know you can do these things.
Developers that use our General Public Licenses protect your rights
with two steps: (1) assert copyright on the software, and (2) offer
you this License which gives you legal permission to copy, distribute
and/or modify the software.
A secondary benefit of defending all users' freedom is that
improvements made in alternate versions of the program, if they
receive widespread use, become available for other developers to
incorporate. Many developers of free software are heartened and
encouraged by the resulting cooperation. However, in the case of
software used on network servers, this result may fail to come about.
The GNU General Public License permits making a modified version and
letting the public access it on a server without ever releasing its
source code to the public.
The GNU Affero General Public License is designed specifically to
ensure that, in such cases, the modified source code becomes available
to the community. It requires the operator of a network server to
provide the source code of the modified version running there to the
users of that server. Therefore, public use of a modified version, on
a publicly accessible server, gives the public access to the source
code of the modified version.
An older license, called the Affero General Public License and
published by Affero, was designed to accomplish similar goals. This is
a different license, not a version of the Affero GPL, but Affero has
released a new version of the Affero GPL which permits relicensing
under this license.
The precise terms and conditions for copying, distribution and
modification follow.
## TERMS AND CONDITIONS
### 0. Definitions.
"This License" refers to version 3 of the GNU Affero General Public
License.
"Copyright" also means copyright-like laws that apply to other kinds
of works, such as semiconductor masks.
"The Program" refers to any copyrightable work licensed under this
License. Each licensee is addressed as "you". "Licensees" and
"recipients" may be individuals or organizations.
To "modify" a work means to copy from or adapt all or part of the work
in a fashion requiring copyright permission, other than the making of
an exact copy. The resulting work is called a "modified version" of
the earlier work or a work "based on" the earlier work.
A "covered work" means either the unmodified Program or a work based
on the Program.
To "propagate" a work means to do anything with it that, without
permission, would make you directly or secondarily liable for
infringement under applicable copyright law, except executing it on a
computer or modifying a private copy. Propagation includes copying,
distribution (with or without modification), making available to the
public, and in some countries other activities as well.
To "convey" a work means any kind of propagation that enables other
parties to make or receive copies. Mere interaction with a user
through a computer network, with no transfer of a copy, is not
conveying.
An interactive user interface displays "Appropriate Legal Notices" to
the extent that it includes a convenient and prominently visible
feature that (1) displays an appropriate copyright notice, and (2)
tells the user that there is no warranty for the work (except to the
extent that warranties are provided), that licensees may convey the
work under this License, and how to view a copy of this License. If
the interface presents a list of user commands or options, such as a
menu, a prominent item in the list meets this criterion.
### 1. Source Code.
The "source code" for a work means the preferred form of the work for
making modifications to it. "Object code" means any non-source form of
a work.
A "Standard Interface" means an interface that either is an official
standard defined by a recognized standards body, or, in the case of
interfaces specified for a particular programming language, one that
is widely used among developers working in that language.
The "System Libraries" of an executable work include anything, other
than the work as a whole, that (a) is included in the normal form of
packaging a Major Component, but which is not part of that Major
Component, and (b) serves only to enable use of the work with that
Major Component, or to implement a Standard Interface for which an
implementation is available to the public in source code form. A
"Major Component", in this context, means a major essential component
(kernel, window system, and so on) of the specific operating system
(if any) on which the executable work runs, or a compiler used to
produce the work, or an object code interpreter used to run it.
The "Corresponding Source" for a work in object code form means all
the source code needed to generate, install, and (for an executable
work) run the object code and to modify the work, including scripts to
control those activities. However, it does not include the work's
System Libraries, or general-purpose tools or generally available free
programs which are used unmodified in performing those activities but
which are not part of the work. For example, Corresponding Source
includes interface definition files associated with source files for
the work, and the source code for shared libraries and dynamically
linked subprograms that the work is specifically designed to require,
such as by intimate data communication or control flow between those
subprograms and other parts of the work.
The Corresponding Source need not include anything that users can
regenerate automatically from other parts of the Corresponding Source.
The Corresponding Source for a work in source code form is that same
work.
### 2. Basic Permissions.
All rights granted under this License are granted for the term of
copyright on the Program, and are irrevocable provided the stated
conditions are met. This License explicitly affirms your unlimited
permission to run the unmodified Program. The output from running a
covered work is covered by this License only if the output, given its
content, constitutes a covered work. This License acknowledges your
rights of fair use or other equivalent, as provided by copyright law.
You may make, run and propagate covered works that you do not convey,
without conditions so long as your license otherwise remains in force.
You may convey covered works to others for the sole purpose of having
them make modifications exclusively for you, or provide you with
facilities for running those works, provided that you comply with the
terms of this License in conveying all material for which you do not
control copyright. Those thus making or running the covered works for
you must do so exclusively on your behalf, under your direction and
control, on terms that prohibit them from making any copies of your
copyrighted material outside their relationship with you.
Conveying under any other circumstances is permitted solely under the
conditions stated below. Sublicensing is not allowed; section 10 makes
it unnecessary.
### 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological
measure under any applicable law fulfilling obligations under article
11 of the WIPO copyright treaty adopted on 20 December 1996, or
similar laws prohibiting or restricting circumvention of such
measures.
When you convey a covered work, you waive any legal power to forbid
circumvention of technological measures to the extent such
circumvention is effected by exercising rights under this License with
respect to the covered work, and you disclaim any intention to limit
operation or modification of the work as a means of enforcing, against
the work's users, your or third parties' legal rights to forbid
circumvention of technological measures.
### 4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program's source code as you
receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice;
keep intact all notices stating that this License and any
non-permissive terms added in accord with section 7 apply to the code;
keep intact all notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.
### 5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to
produce it from the Program, in the form of source code under the
terms of section 4, provided that you also meet all of these
conditions:
- a) The work must carry prominent notices stating that you modified
it, and giving a relevant date.
- b) The work must carry prominent notices stating that it is
released under this License and any conditions added under
section 7. This requirement modifies the requirement in section 4
to "keep intact all notices".
- c) You must license the entire work, as a whole, under this
License to anyone who comes into possession of a copy. This
License will therefore apply, along with any applicable section 7
additional terms, to the whole of the work, and all its parts,
regardless of how they are packaged. This License gives no
permission to license the work in any other way, but it does not
invalidate such permission if you have separately received it.
- d) If the work has interactive user interfaces, each must display
Appropriate Legal Notices; however, if the Program has interactive
interfaces that do not display Appropriate Legal Notices, your
work need not make them do so.
A compilation of a covered work with other separate and independent
works, which are not by their nature extensions of the covered work,
and which are not combined with it such as to form a larger program,
in or on a volume of a storage or distribution medium, is called an
"aggregate" if the compilation and its resulting copyright are not
used to limit the access or legal rights of the compilation's users
beyond what the individual works permit. Inclusion of a covered work
in an aggregate does not cause this License to apply to the other
parts of the aggregate.
### 6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms of
sections 4 and 5, provided that you also convey the machine-readable
Corresponding Source under the terms of this License, in one of these
ways:
- a) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by the
Corresponding Source fixed on a durable physical medium
customarily used for software interchange.
- b) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by a
written offer, valid for at least three years and valid for as
long as you offer spare parts or customer support for that product
model, to give anyone who possesses the object code either (1) a
copy of the Corresponding Source for all the software in the
product that is covered by this License, on a durable physical
medium customarily used for software interchange, for a price no
more than your reasonable cost of physically performing this
conveying of source, or (2) access to copy the Corresponding
Source from a network server at no charge.
- c) Convey individual copies of the object code with a copy of the
written offer to provide the Corresponding Source. This
alternative is allowed only occasionally and noncommercially, and
only if you received the object code with such an offer, in accord
with subsection 6b.
- d) Convey the object code by offering access from a designated
place (gratis or for a charge), and offer equivalent access to the
Corresponding Source in the same way through the same place at no
further charge. You need not require recipients to copy the
Corresponding Source along with the object code. If the place to
copy the object code is a network server, the Corresponding Source
may be on a different server (operated by you or a third party)
that supports equivalent copying facilities, provided you maintain
clear directions next to the object code saying where to find the
Corresponding Source. Regardless of what server hosts the
Corresponding Source, you remain obligated to ensure that it is
available for as long as needed to satisfy these requirements.
- e) Convey the object code using peer-to-peer transmission,
provided you inform other peers where the object code and
Corresponding Source of the work are being offered to the general
public at no charge under subsection 6d.
A separable portion of the object code, whose source code is excluded
from the Corresponding Source as a System Library, need not be
included in conveying the object code work.
A "User Product" is either (1) a "consumer product", which means any
tangible personal property which is normally used for personal,
family, or household purposes, or (2) anything designed or sold for
incorporation into a dwelling. In determining whether a product is a
consumer product, doubtful cases shall be resolved in favor of
coverage. For a particular product received by a particular user,
"normally used" refers to a typical or common use of that class of
product, regardless of the status of the particular user or of the way
in which the particular user actually uses, or expects or is expected
to use, the product. A product is a consumer product regardless of
whether the product has substantial commercial, industrial or
non-consumer uses, unless such uses represent the only significant
mode of use of the product.
"Installation Information" for a User Product means any methods,
procedures, authorization keys, or other information required to
install and execute modified versions of a covered work in that User
Product from a modified version of its Corresponding Source. The
information must suffice to ensure that the continued functioning of
the modified object code is in no case prevented or interfered with
solely because modification has been made.
If you convey an object code work under this section in, or with, or
specifically for use in, a User Product, and the conveying occurs as
part of a transaction in which the right of possession and use of the
User Product is transferred to the recipient in perpetuity or for a
fixed term (regardless of how the transaction is characterized), the
Corresponding Source conveyed under this section must be accompanied
by the Installation Information. But this requirement does not apply
if neither you nor any third party retains the ability to install
modified object code on the User Product (for example, the work has
been installed in ROM).
The requirement to provide Installation Information does not include a
requirement to continue to provide support service, warranty, or
updates for a work that has been modified or installed by the
recipient, or for the User Product in which it has been modified or
installed. Access to a network may be denied when the modification
itself materially and adversely affects the operation of the network
or violates the rules and protocols for communication across the
network.
Corresponding Source conveyed, and Installation Information provided,
in accord with this section must be in a format that is publicly
documented (and with an implementation available to the public in
source code form), and must require no special password or key for
unpacking, reading or copying.
### 7. Additional Terms.
"Additional permissions" are terms that supplement the terms of this
License by making exceptions from one or more of its conditions.
Additional permissions that are applicable to the entire Program shall
be treated as though they were included in this License, to the extent
that they are valid under applicable law. If additional permissions
apply only to part of the Program, that part may be used separately
under those permissions, but the entire Program remains governed by
this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option
remove any additional permissions from that copy, or from any part of
it. (Additional permissions may be written to require their own
removal in certain cases when you modify the work.) You may place
additional permissions on material, added by you to a covered work,
for which you have or can give appropriate copyright permission.
Notwithstanding any other provision of this License, for material you
add to a covered work, you may (if authorized by the copyright holders
of that material) supplement the terms of this License with terms:
- a) Disclaiming warranty or limiting liability differently from the
terms of sections 15 and 16 of this License; or
- b) Requiring preservation of specified reasonable legal notices or
author attributions in that material or in the Appropriate Legal
Notices displayed by works containing it; or
- c) Prohibiting misrepresentation of the origin of that material,
or requiring that modified versions of such material be marked in
reasonable ways as different from the original version; or
- d) Limiting the use for publicity purposes of names of licensors
or authors of the material; or
- e) Declining to grant rights under trademark law for use of some
trade names, trademarks, or service marks; or
- f) Requiring indemnification of licensors and authors of that
material by anyone who conveys the material (or modified versions
of it) with contractual assumptions of liability to the recipient,
for any liability that these contractual assumptions directly
impose on those licensors and authors.
All other non-permissive additional terms are considered "further
restrictions" within the meaning of section 10. If the Program as you
received it, or any part of it, contains a notice stating that it is
governed by this License along with a term that is a further
restriction, you may remove that term. If a license document contains
a further restriction but permits relicensing or conveying under this
License, you may add to a covered work material governed by the terms
of that license document, provided that the further restriction does
not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you
must place, in the relevant source files, a statement of the
additional terms that apply to those files, or a notice indicating
where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the
form of a separately written license, or stated as exceptions; the
above requirements apply either way.
### 8. Termination.
You may not propagate or modify a covered work except as expressly
provided under this License. Any attempt otherwise to propagate or
modify it is void, and will automatically terminate your rights under
this License (including any patent licenses granted under the third
paragraph of section 11).
However, if you cease all violation of this License, then your license
from a particular copyright holder is reinstated (a) provisionally,
unless and until the copyright holder explicitly and finally
terminates your license, and (b) permanently, if the copyright holder
fails to notify you of the violation by some reasonable means prior to
60 days after the cessation.
Moreover, your license from a particular copyright holder is
reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you have
received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after
your receipt of the notice.
Termination of your rights under this section does not terminate the
licenses of parties who have received copies or rights from you under
this License. If your rights have been terminated and not permanently
reinstated, you do not qualify to receive new licenses for the same
material under section 10.
### 9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or run
a copy of the Program. Ancillary propagation of a covered work
occurring solely as a consequence of using peer-to-peer transmission
to receive a copy likewise does not require acceptance. However,
nothing other than this License grants you permission to propagate or
modify any covered work. These actions infringe copyright if you do
not accept this License. Therefore, by modifying or propagating a
covered work, you indicate your acceptance of this License to do so.
### 10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically
receives a license from the original licensors, to run, modify and
propagate that work, subject to this License. You are not responsible
for enforcing compliance by third parties with this License.
An "entity transaction" is a transaction transferring control of an
organization, or substantially all assets of one, or subdividing an
organization, or merging organizations. If propagation of a covered
work results from an entity transaction, each party to that
transaction who receives a copy of the work also receives whatever
licenses to the work the party's predecessor in interest had or could
give under the previous paragraph, plus a right to possession of the
Corresponding Source of the work from the predecessor in interest, if
the predecessor has it or can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the
rights granted or affirmed under this License. For example, you may
not impose a license fee, royalty, or other charge for exercise of
rights granted under this License, and you may not initiate litigation
(including a cross-claim or counterclaim in a lawsuit) alleging that
any patent claim is infringed by making, using, selling, offering for
sale, or importing the Program or any portion of it.
### 11. Patents.
A "contributor" is a copyright holder who authorizes use under this
License of the Program or a work on which the Program is based. The
work thus licensed is called the contributor's "contributor version".
A contributor's "essential patent claims" are all patent claims owned
or controlled by the contributor, whether already acquired or
hereafter acquired, that would be infringed by some manner, permitted
by this License, of making, using, or selling its contributor version,
but do not include claims that would be infringed only as a
consequence of further modification of the contributor version. For
purposes of this definition, "control" includes the right to grant
patent sublicenses in a manner consistent with the requirements of
this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free
patent license under the contributor's essential patent claims, to
make, use, sell, offer for sale, import and otherwise run, modify and
propagate the contents of its contributor version.
In the following three paragraphs, a "patent license" is any express
agreement or commitment, however denominated, not to enforce a patent
(such as an express permission to practice a patent or covenant not to
sue for patent infringement). To "grant" such a patent license to a
party means to make such an agreement or commitment not to enforce a
patent against the party.
If you convey a covered work, knowingly relying on a patent license,
and the Corresponding Source of the work is not available for anyone
to copy, free of charge and under the terms of this License, through a
publicly available network server or other readily accessible means,
then you must either (1) cause the Corresponding Source to be so
available, or (2) arrange to deprive yourself of the benefit of the
patent license for this particular work, or (3) arrange, in a manner
consistent with the requirements of this License, to extend the patent
license to downstream recipients. "Knowingly relying" means you have
actual knowledge that, but for the patent license, your conveying the
covered work in a country, or your recipient's use of the covered work
in a country, would infringe one or more identifiable patents in that
country that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or
arrangement, you convey, or propagate by procuring conveyance of, a
covered work, and grant a patent license to some of the parties
receiving the covered work authorizing them to use, propagate, modify
or convey a specific copy of the covered work, then the patent license
you grant is automatically extended to all recipients of the covered
work and works based on it.
A patent license is "discriminatory" if it does not include within the
scope of its coverage, prohibits the exercise of, or is conditioned on
the non-exercise of one or more of the rights that are specifically
granted under this License. You may not convey a covered work if you
are a party to an arrangement with a third party that is in the
business of distributing software, under which you make payment to the
third party based on the extent of your activity of conveying the
work, and under which the third party grants, to any of the parties
who would receive the covered work from you, a discriminatory patent
license (a) in connection with copies of the covered work conveyed by
you (or copies made from those copies), or (b) primarily for and in
connection with specific products or compilations that contain the
covered work, unless you entered into that arrangement, or that patent
license was granted, prior to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting
any implied license or other defenses to infringement that may
otherwise be available to you under applicable patent law.
### 12. No Surrender of Others' Freedom.
If conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot convey a
covered work so as to satisfy simultaneously your obligations under
this License and any other pertinent obligations, then as a
consequence you may not convey it at all. For example, if you agree to
terms that obligate you to collect a royalty for further conveying
from those to whom you convey the Program, the only way you could
satisfy both those terms and this License would be to refrain entirely
from conveying the Program.
### 13. Remote Network Interaction; Use with the GNU General Public License.
Notwithstanding any other provision of this License, if you modify the
Program, your modified version must prominently offer all users
interacting with it remotely through a computer network (if your
version supports such interaction) an opportunity to receive the
Corresponding Source of your version by providing access to the
Corresponding Source from a network server at no charge, through some
standard or customary means of facilitating copying of software. This
Corresponding Source shall include the Corresponding Source for any
work covered by version 3 of the GNU General Public License that is
incorporated pursuant to the following paragraph.
Notwithstanding any other provision of this License, you have
permission to link or combine any covered work with a work licensed
under version 3 of the GNU General Public License into a single
combined work, and to convey the resulting work. The terms of this
License will continue to apply to the part which is the covered work,
but the work with which it is combined will remain governed by version
3 of the GNU General Public License.
### 14. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions
of the GNU Affero General Public License from time to time. Such new
versions will be similar in spirit to the present version, but may
differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies that a certain numbered version of the GNU Affero General
Public License "or any later version" applies to it, you have the
option of following the terms and conditions either of that numbered
version or of any later version published by the Free Software
Foundation. If the Program does not specify a version number of the
GNU Affero General Public License, you may choose any version ever
published by the Free Software Foundation.
If the Program specifies that a proxy can decide which future versions
of the GNU Affero General Public License can be used, that proxy's
public statement of acceptance of a version permanently authorizes you
to choose that version for the Program.
Later license versions may give you additional or different
permissions. However, no additional obligations are imposed on any
author or copyright holder as a result of your choosing to follow a
later version.
### 15. Disclaimer of Warranty.
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT
WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT
LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR
A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE
DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
CORRECTION.
### 16. Limitation of Liability.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR
CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES
ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT
NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR
LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM
TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
### 17. Interpretation of Sections 15 and 16.
If the disclaimer of warranty and limitation of liability provided
above cannot be given local legal effect according to their terms,
reviewing courts shall apply local law that most closely approximates
an absolute waiver of all civil liability in connection with the
Program, unless a warranty or assumption of liability accompanies a
copy of the Program in return for a fee.
END OF TERMS AND CONDITIONS
## How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these
terms.
To do so, attach the following notices to the program. It is safest to
attach them to the start of each source file to most effectively state
the exclusion of warranty; and each file should have at least the
"copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software: you can redistribute it and/or modify
it under the terms of the GNU Affero General Public License as
published by the Free Software Foundation, either version 3 of the
License, or (at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU Affero General Public License for more details.
You should have received a copy of the GNU Affero General Public License
along with this program. If not, see <https://www.gnu.org/licenses/>.
Also add information on how to contact you by electronic and paper
mail.
If your software can interact with users remotely through a computer
network, you should also make sure that it provides a way for users to
get its source. For example, if your program is a web application, its
interface could display a "Source" link that leads users to an archive
of the code. There are many ways you could offer source, and different
solutions will be better for different programs; see section 13 for
the specific requirements.
You should also get your employer (if you work as a programmer) or
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. For more information on this, and how to apply and follow
the GNU AGPL, see <https://www.gnu.org/licenses/>.

# gege-jdr-backend
## Getting Started
These instructions will give you a copy of the project up and running
on your local machine for development and testing purposes. See
deployment for notes on deploying the project on a live system.
### Prerequisites
You have two options for getting started: installing all the
requirements locally, or using the included Nix development shell with
[Nix flakes](https://nixos.wiki/wiki/flakes).
#### Nix development shell
If you have [`direnv`](https://direnv.net/) installed on your machine,
run `direnv allow .` at the root of this project to automatically
enter the Nix development shell for gege-jdr-backend.
Otherwise, you can simply run `nix develop` at the root of the project.
All the necessary tools will be installed automatically, except for
Docker (see below).
#### Manually installing the prerequisites
If you decide to install everything manually, you will need the
following tools:
- [Rust](https://www.rust-lang.org/), in particular `cargo`. This
project uses a precise version of Rust, check the
[rust-toolchain.toml](./rust-toolchain.toml) file for more
information;
- [sqlx-cli](https://github.com/launchbadge/sqlx/tree/main/sqlx-cli),
necessary for creating the database used by the backend and running
its migrations;
- [just](https://just.systems/), an alternative to Makefiles, for
running commands more easily;
- [cargo-audit](https://github.com/rustsec/rustsec/tree/main/cargo-audit),
to verify whether the project contains known vulnerabilities;
- [cargo-auditable](https://github.com/rust-secure-code/cargo-auditable),
to audit the compiled binaries;
- [cargo-tarpaulin](https://github.com/xd009642/tarpaulin), a code
coverage tool for Rust;
- [cargo-msrv](https://crates.io/crates/cargo-msrv), to check whether
your code respects the minimum supported Rust version used by this
project.
It is also recommended, though not necessary, to have the following
tools installed:
- [bacon](https://dystroy.org/bacon/), to automatically run cargo
commands on code changes;
- [Docker](https://www.docker.com/) to easily spin up a PostgreSQL
database required by the backend, as well as Mailpit (see below)
- [Mailpit](https://mailpit.axllent.org/) to easily test sending
emails without the need of a real SMTP server (included in the
default dev Docker Compose file);
- [rust-analyzer](https://rust-analyzer.github.io/), the *de facto*
standard LSP server for Rust;
- [sqls](https://github.com/sqls-server/sqls), an SQL LSP server,
useful when editing SQL files for migrations or tests.
### Installing
Start by cloning the repository to your local machine:
```sh
$ git clone https://labs.phundrak.com/phundrak/gege-jdr-backend.git
$ cd gege-jdr-backend
```
Then, copy the `.env.example` file to a `.env` file and adjust it as
you see fit.
As mentioned above, if you have [Nix
flakes](https://nixos.wiki/wiki/flakes) and
[direnv](https://direnv.net/) installed, you can simply run
`direnv allow .` to automatically set up your development environment.
Otherwise, you should install every required tool yourself (including,
if you want, the optional tools).
You should then spin up a PostgreSQL database gege-jdr-backend will be
using. You can do it manually, or you can spin up the Docker Compose
file included with this repository.
```sh
just docker-start
```
This will launch a PostgreSQL 16 container based on the content of the
`.env` file you created earlier.
To stop the Docker containers, simply run the following command:
```sh
just docker-stop
```
## Running the project
To run the project, you can run one of the two following commands:
```sh
just run # starts the Docker containers automatically before
# launching the project
just run-no-docker # runs the project without the Docker containers
```
## Running the tests
There are two ways to run the tests of gege-jdr-backend. The first one is
the usual `cargo run`, which you can run with `just run`. It will
simply run the tests and fail if one of them or more fails.
There is a second option:
```sh
just coverage
```
This command will run all the tests of the project and generate a code
coverage report for gege-jdr-backend in the `coverage/` directory. You
will find both the `lcov` coverage file for the project, as well as an
HTML file you can open in your browser to explore which line of code
is covered or not. And, as with `just test`, if at least one of these
tests fails, the code coverage will fail too and will display the same
information.
**NOTE**: The CI pipeline will run `just coverage` and will fail if
any of the tests fails or if the code coverage drops below 60% of code
covered by tests.
### Linting
This project uses [clippy](https://github.com/rust-lang/rust-clippy)
for linting the project. You can run it with the following command:
```sh
just lint
```
**NOTE*: The CI pipeline will run `just lint` and will fail if the
command fails too. It is strongly recommended to fix any issue from
clippy before opening a pull request.
### Style test
This project uses [rustfmt](https://github.com/rust-lang/rustfmt) to format its code. You can format your code with this command:
```sh
just format
```
You can also check if your code is properly formatted with:
```sh
just format-check
```
