# Contributor Covenant Code of Conduct
## Our Pledge
We as members, contributors, and leaders pledge to make participation in our
community a harassment-free experience for everyone, regardless of age, body
size, visible or invisible disability, ethnicity, sex characteristics, gender
identity and expression, level of experience, education, socio-economic status,
nationality, personal appearance, race, caste, color, religion, or sexual
identity and orientation.
We pledge to act and interact in ways that contribute to an open, welcoming,
diverse, inclusive, and healthy community.
## 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 of
any kind
- 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
## Enforcement Responsibilities
Community leaders 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.
Community leaders 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 email 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
<olivia.a.brooks77@gmail.com>.
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.

= kramer
:toc:
// Hello people reading the README source :)
== Prelude
VERY EARLY ALPHA -- NOT YET FUNCTIONAL
I needed a program to efficiently repair the data on optical discs.
== Goals
* [*] CLI Args
** [*] Input device
** [*] Output file (ISO 9660)
** [*] Repair map file
** [*] sequence_length
** [*] brute_passes
** [*] Sector size override?
* Repair Algorithm
** Stage 1: Trial
*** [ ] 1 - From first sector, parse forward to error.
*** [ ] 2 - From last sector, parse backwards to error.
*** [ ] 3 - From center of data for trial, parse forward to error or end of remaining trial domain.
*** [ ] 4 - Stripe-skip remaining data, attempting to read largest trial domains first.
**** [ ] If data keeps reading good, no skip will occur until an error is reached.
** Stage 2: Isolation
*** [ ] From largest to smallest untrustworthy sequence, attempt to read each sequence at half sequence_length.
*** [ ] Same, but at quarter sequence_length.
*** [ ] Same, but at eighth sequence_length.
*** [ ] By sector, parse untrustworthy sequences from start to error, and end to error. Mark mid section for brute force.
** Stage 3: Brute Force
*** [ ] Desperately attempt to recover data from marked sections.
*** [ ] Attempt for brute_passes, retrying all failed sectors.
* [ ] Repair Map
** [ ] I'll figure out some kind of language for this...

# kramer
`kramer` is a data recovery utility for optical media.
There are plans to change the project name, but during initial development it
will continue to be referred to as kramer.
This is still in very early development, so expect old maps to no longer work.
## Plans
### Core
- [x] Mapping
- [x] Record the state of disc regions
- [x] Recover from saved map.
- [ ] Recovery
- [x] Initial
Technically there is an outstanding issue with sleepy firmware here,
but beside that this technically works.
- [ ] Patchworking
- [ ] Isolate
- [ ] Scraping
- [ ] CLI
- [x] Arguments
- [ ] Recovery progress
- [ ] Recovery stats
- [ ] Documentation, eugh.
### Extra
- [ ] i18n
- [ ] English
- [ ] French
- [ ] TUI (akin to `ddrescueview`)
- [ ] Visual status map
- [ ] Recovery properties
- [ ] Recovery progress
- [ ] Recovery stats
## Recovery Strategy
### Initial Pass (Stage::Untested)
Tries to read clusters of `max_buffer_size`, marking clusters with errors as
`ForIsolation` (note that the name has not yet be updated to
`Patchwork{ depth }`).
### Patchworking
This works by halving the length of the read buffer until one of two
conditions is met:
1. `max_buffer_size` has been divided by `max_buffer_subdivision`
(like a maximum recursion depth).
Effectively, it will keep running `max_buffer_size / isolation_depth;
isolation_depth++;` on each pass until `isolation_depth ==
max_buffer_subdivision`
2. `buffer_size <= min_buffer_size`
3. `buffer_size <= sector_size`
### Isolate
This is where we reach brute forcing territory. `ddrescue` refers to this as
trimming. `kramer` implements the same technique. However, thanks to the
patchworking pass, this sector-at-a-time reading can be minimized, hopefully
reducing wear and overall recovery time on drives with a very short spin-down
delay.
### Scraping
This is the pure brute force, sector-at-a-time read. This has identical
behaviour to `ddrescue`'s scraping phase.
