# 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.

// 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.
