## Our Pledge

In the interest of fostering an open and welcoming environment, we as
contributors and maintainers pledge to making 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 creating a positive environment
include:

* Using welcoming and inclusive language
* Being respectful of differing viewpoints and experiences
* Gracefully accepting constructive criticism
* Focusing on what is best for the community
* Showing empathy towards other community members

Examples of unacceptable behavior by participants include:

* The use of sexualized language or imagery and unwelcome sexual attention or
 advances
* Trolling, insulting/derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or electronic
 address, without explicit permission
* Other conduct which could reasonably be considered inappropriate in a
 professional setting

## Our Responsibilities

Project maintainers are responsible for clarifying the standards of acceptable
behavior and are expected to take appropriate and fair corrective action in
response to any instances of unacceptable behavior.

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, or to ban temporarily or
permanently any contributor for other behaviors that they deem inappropriate,
threatening, offensive, or harmful.

## Scope

This Code of Conduct applies both within project spaces and in public spaces
when an individual is representing the project or its community. Examples of
representing a project or community include using an official project e-mail
address, posting via an official social media account, or acting as an appointed
representative at an online or offline event. Representation of a project may be
further defined and clarified by project maintainers.

## Enforcement

Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported by contacting the project team at contact@process-one.net. All
complaints will be reviewed and investigated and will result in a response that
is deemed necessary and appropriate to the circumstances. The project team is
obligated to maintain confidentiality with regard to the reporter of an incident.
Further details of specific enforcement policies may be posted separately.

Project maintainers who do not follow or enforce the Code of Conduct in good
faith may face temporary or permanent repercussions as determined by other
members of the project's leadership.

## Attribution

This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
available at https://www.contributor-covenant.org/version/1/4/code-of-conduct.html

07070100000007000081A4000000000000000000000001626FB04100001793000000000000000000000000000000000000002100000000cache_tab-1.0.30/CONTRIBUTING.md# Contributing

We'd love for you to contribute to our source code and to make our project even better than it is
today! Here are the guidelines we'd like you to follow:

* [Code of Conduct](#coc)
* [Questions and Problems](#question)
* [Issues and Bugs](#issue)
* [Feature Requests](#feature)
* [Issue Submission Guidelines](#submit)
* [Pull Request Submission Guidelines](#submit-pr)
* [Signing the CLA](#cla)

## <a name="coc"></a> Code of Conduct

Help us keep our community open-minded and inclusive. Please read and follow our [Code of Conduct][coc].

## <a name="requests"></a> Questions, Bugs, Features

### <a name="question"></a> Got a Question or Problem?

Do not open issues for general support questions as we want to keep GitHub issues for bug reports
and feature requests. You've got much better chances of getting your question answered on dedicated
support platforms, the best being [Stack Overflow][stackoverflow].

Stack Overflow is a much better place to ask questions since:

- there are thousands of people willing to help on Stack Overflow
- questions and answers stay available for public viewing so your question / answer might help
  someone else
- Stack Overflow's voting system assures that the best answers are prominently visible.

To save your and our time, we will systematically close all issues that are requests for general
support and redirect people to the section you are reading right now.

### <a name="issue"></a> Found an Issue or Bug?

If you find a bug in the source code, you can help us by submitting an issue to our
[GitHub Repository][github]. Even better, you can submit a Pull Request with a fix.

### <a name="feature"></a> Missing a Feature?

You can request a new feature by submitting an issue to our [GitHub Repository][github-issues].

If you would like to implement a new feature then consider what kind of change it is:

* **Major Changes** that you wish to contribute to the project should be discussed first in an
  [GitHub issue][github-issues] that clearly outlines the changes and benefits of the feature.
* **Small Changes** can directly be crafted and submitted to the [GitHub Repository][github]
  as a Pull Request. See the section about [Pull Request Submission Guidelines](#submit-pr).

## <a name="submit"></a> Issue Submission Guidelines

Before you submit your issue search the archive, maybe your question was already answered.

If your issue appears to be a bug, and hasn't been reported, open a new issue. Help us to maximize
the effort we can spend fixing issues and adding new features, by not reporting duplicate issues.

The "[new issue][github-new-issue]" form contains a number of prompts that you should fill out to
make it easier to understand and categorize the issue.

## <a name="submit-pr"></a> Pull Request Submission Guidelines

By submitting a pull request for a code or doc contribution, you need to have the right
to grant your contribution's copyright license to ProcessOne. Please check [ProcessOne CLA][cla]
for details.

Before you submit your pull request consider the following guidelines:

* Search [GitHub][github-pr] for an open or closed Pull Request
  that relates to your submission. You don't want to duplicate effort.
* Make your changes in a new git branch:

```shell
    git checkout -b my-fix-branch master
    ```
* Test your changes and, if relevant, expand the automated test suite.
* Create your patch commit, including appropriate test cases.
* If the changes affect public APIs, change or add relevant documentation.
* Commit your changes using a descriptive commit message.

```shell
    git commit -a
    ```
  Note: the optional commit `-a` command line option will automatically "add" and "rm" edited files.

* Push your branch to GitHub:

```shell
    git push origin my-fix-branch
    ```

* In GitHub, send a pull request to `master` branch. This will trigger the continuous integration and run the test.
We will also notify you if you have not yet signed the [contribution agreement][cla].

* If you find that the continunous integration has failed, look into the logs to find out
if your changes caused test failures, the commit message was malformed etc. If you find that the
tests failed or times out for unrelated reasons, you can ping a team member so that the build can be
restarted.

* If we suggest changes, then:

* Make the required updates.
  * Test your changes and test cases.
  * Commit your changes to your branch (e.g. `my-fix-branch`).
  * Push the changes to your GitHub repository (this will update your Pull Request).

You can also amend the initial commits and force push them to the branch.

```shell
    git rebase master -i
    git push origin my-fix-branch -f
    ```

This is generally easier to follow, but separate commits are useful if the Pull Request contains
    iterations that might be interesting to see side-by-side.

That's it! Thank you for your contribution!

## <a name="cla"></a> Signing the Contributor License Agreement (CLA)

Upon submitting a Pull Request, we will ask you to sign our CLA if you haven't done
so before. It's a quick process, we promise, and you will be able to do it all online

You can read [ProcessOne Contribution License Agreement][cla] in PDF.

This is part of the legal framework of the open-source ecosystem that adds some red tape,
but protects both the contributor and the company / foundation behind the project. It also
gives us the option to relicense the code with a more permissive license in the future.

      (an example is provided in the Appendix below).

"Derivative Works" shall mean any work, whether in Source or Object
      form, that is based on (or derived from) the Work and for which the

2. Grant of Copyright License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      copyright license to reproduce, prepare Derivative Works of,
      publicly display, publicly perform, sublicense, and distribute the
      Work and such Derivative Works in Source or Object form.

3. Grant of Patent License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      (except as stated in this section) patent license to make, have made,
      use, offer to sell, sell, import, and otherwise transfer the Work,
      where such license applies only to those patent claims licensable
      by such Contributor that are necessarily infringed by their
      Contribution(s) alone or by combination of their Contribution(s)
      with the Work to which such Contribution(s) was submitted. If You
      institute patent litigation against any entity (including a
      cross-claim or counterclaim in a lawsuit) alleging that the Work
      or a Contribution incorporated within the Work constitutes direct
      or contributory patent infringement, then any patent licenses
      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.

4. Redistribution. You may reproduce and distribute copies of the
      Work or Derivative Works thereof in any medium, with or without
      modifications, and in Source or Object form, provided that You
      meet the following conditions:

(a) You must give any other recipients of the Work or
          Derivative Works a copy of this License; and

(b) You must cause any modified files to carry prominent notices
          stating that You changed the files; and

(c) You must retain, in the Source form of any Derivative Works
          that You distribute, all copyright, patent, trademark, and
          attribution notices from the Source form of the Work,
          excluding those notices that do not pertain to any part of
          the Derivative Works; and

(d) If the Work includes a "NOTICE" text file as part of its
          distribution, then any Derivative Works that You distribute must
          include a readable copy of the attribution notices contained
          within such NOTICE file, excluding those notices that do not
          pertain to any part of the Derivative Works, in at least one
          of the following places: within a NOTICE text file distributed
          as part of the Derivative Works; within the Source form or
          documentation, if provided along with the Derivative Works; or,
          within a display generated by the Derivative Works, if and
          wherever such third-party notices normally appear. The contents
          of the NOTICE file are for informational purposes only and
          do not modify the License. You may add Your own attribution
          notices within Derivative Works that You distribute, alongside
          or as an addendum to the NOTICE text from the Work, provided
          that such additional attribution notices cannot be construed
          as modifying the License.

You may add Your own copyright statement to Your modifications and

5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.

7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all

[![CI](https://github.com/processone/cache_tab/actions/workflows/ci.yml/badge.svg?branch=master)](https://github.com/processone/cache_tab/actions/workflows/ci.yml)
[![Coverage Status](https://coveralls.io/repos/processone/cache_tab/badge.svg?branch=master&service=github)](https://coveralls.io/github/processone/cache_tab?branch=master)
[![Hex version](https://img.shields.io/hexpm/v/cache_tab.svg "Hex version")](https://hex.pm/packages/cache_tab)

`cache_tab` application is intended to proxy back-end operations for
Key-Value insert, lookup and delete and maintain a cache of those
Key-Values in-memory, to save back-end operations.

Operations are intended to be atomic between back-end and cache
tables.

The lifetime of the cache object and the max size of the cache can be
defined as table parameters to limit the size of the in-memory tables.

## Building

`cache_tab` application can be build as follow:

make

It is a rebar-compatible OTP application. Alternatively, you can build
it with rebar:

rebar get-deps compile

## Usage

You can start the application with the command:

```
$ erl -pa ebin -pa deps/*/ebin
Erlang/OTP 18 [erts-7.1] [source] [64-bit] [smp:4:4] [async-threads:10] [hipe] [kernel-poll:false] [dtrace]

Eshell V7.1  (abort with ^G)
1> application:start(cache_tab).
```

Then, you can create a table for a specific type of data to cache. You
can create several tables to separate your cached data. The following
command will create a table named `tab_name`:

```
cache_tab:new(tab_name, [{life_time, Seconds}, {max_size, N}]).
```

The optional `life_time` option is used to define cache entry
expiration. The optional `max_size` option is used to limit number of
entries to add in cache.

You can insert data into the cache with:

```
cache_tab:insert(tab_name, <<"key">>, <<"value">>, fun() -> do_something() end).
```

Cache inserts are designed to be able to act as a proxy to backend
insert. That's the purpose of the fun called as last parameter
(`do_something`). Return of the fun is ignored, but if it crashes,
cache will not be stored.  If value did not change compared to
previous insert, the fun will not be called, saving possibly unneeded
write operations

You can also lookup data from the cache:

```
cache_tab:lookup(tab_name, <<"key">>, fun() -> read_value_if_not_cached() end).
```

The fun in last parameter is used to read and cache the value from
your back-end if it is not already in cache.

It is expected to return either `{ok, Value}` or `error`.

You can delete entries from back-end and cache with command:

```
cache_tab:delete(tab_name, <<"key">>, fun() -> do_something() end),
```

Info command will report about the hits / misses to help you tune your
cache size / lifetime parameters:

```
cache_tab:info(tab_name, Info).
```

Info parameter can be: `size`, `ratio` or `all`.

## Development

### Test

#### Unit test

You can run eunit test with the command:

$ make test

\`configure' configures cache_tab 1.0.0 to adapt to many kinds of systems.

Usage: $0 [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE.  See below for descriptions of some of the useful variables.

Defaults for the options are specified in brackets.

Configuration:
  -h, --help              display this help and exit
      --help=short        display options specific to this package
      --help=recursive    display the short help of all the included packages
  -V, --version           display version information and exit
  -q, --quiet, --silent   do not print \`checking ...' messages
      --cache-file=FILE   cache test results in FILE [disabled]
  -C, --config-cache      alias for \`--cache-file=config.cache'
  -n, --no-create         do not create output files
      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

Installation directories:

  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
                          [PREFIX]

By default, \`make install' will install all the files in
\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
an installation prefix other than \`$ac_default_prefix' using \`--prefix',
for instance \`--prefix=\$HOME'.

For better control, use the options below.

Fine tuning of the installation directories:
  --bindir=DIR            user executables [EPREFIX/bin]
  --sbindir=DIR           system admin executables [EPREFIX/sbin]
  --libexecdir=DIR        program executables [EPREFIX/libexec]

Optional Features:
  --disable-option-checking  ignore unrecognized --enable/--with options
  --disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)
  --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
  --enable-gcov           compile with gcov enabled (default: no)

Some influential environment variables:
  CC          C compiler command
  CFLAGS      C compiler flags
  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
              nonstandard directory <lib dir>
  LIBS        libraries to pass to the linker, e.g. -l<library>
  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
              you have headers in a nonstandard directory <include dir>
  CPP         C preprocessor
  ERL         Erlang/OTP interpreter command [autodetected]
  ERLC        Erlang/OTP compiler command [autodetected]
  ERLCFLAGS   Erlang/OTP compiler flags [none]

Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.

Report bugs to the package provider.
