docs/CHANGELOG.md: document v1.79.9 release

- Return immediately on context cancel during the backoff sleep.
  This should help with https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3747

- Add a comment describing why the second attempt to obtain the response from remote side
  is perfromed immediately after the first attempt.

- Remove fasthttp dependency from lib/promscrape/discoveryutils

- Set context deadline before calling doRequestWithPossibleRetry().
  This simplifies the doRequestWithPossibleRetry() a bit.

Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3293

+# Кодекс Поведения участника
+
+## Наши обязательства
+
+Мы, как участники, авторы и лидеры обязуемся сделать участие в сообществе
+свободным от притеснений для всех, независимо от возраста, телосложения,
+видимых или невидимых ограничений способности, этнической принадлежности,
+половых признаков, гендерной идентичности и выражения, уровня опыта,
+образования, социо-экономического статуса, национальности, внешности,
+расы, религии, или сексуальной идентичности и ориентации.
+
+Мы обещаем действовать и взаимодействовать таким образом, чтобы вносить вклад в открытое,
+дружелюбное, многообразное, инклюзивное и здоровое сообщество.
+
+## Наши стандарты
+
+Примеры поведения, создающие условия для благоприятных взаимоотношений включают в себя:
+
+* Проявление доброты и эмпатии к другим участникам проекта
+* Уважение к чужой точке зрения и опыту
+* Конструктивная критика и принятие конструктивной критики
+* Принятие ответственности, принесение извинений тем, кто пострадал от наших ошибок
+  и извлечение уроков из опыта
+* Ориентирование на то, что лучше подходит для сообщества, а не только для нас лично
+
+Примеры неприемлемого поведения участников включают в себя:
+
+* Использование выражений или изображений сексуального характера и нежелательное сексуальное внимание или домогательство в любой форме
+* Троллинг, оскорбительные или уничижительные комментарии, переход на личности или затрагивание политических убеждений
+* Публичное или приватное домогательство
+* Публикация личной информации других лиц, например, физического или электронного адреса, без явного разрешения
+* Иное поведение, которое обоснованно считать неуместным в профессиональной обстановке
+
+## Обязанности
+
+Лидеры сообщества отвечают за разъяснение и применение наших стандартов приемлемого
+поведения и будут предпринимать соответствующие и честные меры по исправлению положения
+в ответ на любое поведение, которое они сочтут неприемлемым, угрожающим, оскорбительным или вредным.
+
+Лидеры сообщества обладают правом и обязанностью удалять, редактировать или отклонять
+комментарии, коммиты, код, изменения в вики, вопросы и другой вклад, который не совпадает
+с Кодексом Поведения, и предоставят причины принятого решения, когда сочтут нужным.
+
+## Область применения
+
+Данный Кодекс Поведения применим во всех во всех публичных физических и цифровых пространства сообщества,
+а также когда человек официально представляет сообщество в публичных местах.
+Примеры представления проекта или сообщества включают использование официальной электронной почты,
+публикации в официальном аккаунте в социальных сетях,
+или упоминания как представителя в онлайн или оффлайн мероприятии.
+
+## Приведение в исполнение
+
+О случаях домогательства, а так же оскорбительного или иного другого неприемлемого
+поведения можно сообщить ответственным лидерам сообщества с помощью письма на info@victoriametrics.com
+Все жалобы будут рассмотрены и расследованы оперативно и беспристрастно.
+
+Все лидеры сообщества обязаны уважать неприкосновенность частной жизни и личную
+неприкосновенность автора сообщения.
+
+## Руководство по исполнению
+
+Лидеры сообщества будут следовать следующим Принципам Воздействия в Сообществе,
+чтобы определить последствия для тех, кого они считают виновными в нарушении данного Кодекса Поведения:
+
+### 1. Исправление
+
+**Общественное влияние**: Использование недопустимой лексики или другое поведение,
+считающиеся непрофессиональным или нежелательным в сообществе.
+
+**Последствия**: Личное, письменное предупреждение от лидеров сообщества,
+объясняющее суть нарушения и почему такое поведение
+было неуместно. Лидеры сообщества могут попросить принести публичное извинение.
+
+### 2. Предупреждение
+
+**Общественное влияние**: Нарушение в результате одного инцидента или серии действий.
+
+**Последствия**: Предупреждение о последствиях в случае продолжающегося неуместного поведения.
+На определенное время не допускается взаимодействие с людьми, вовлеченными в инцидент,
+включая незапрошенное взаимодействие
+с теми, кто обеспечивает соблюдение Кодекса. Это включает в себя избегание взаимодействия
+в публичных пространствах, а так же во внешних каналах,
+таких как социальные сети. Нарушение этих правил влечет за собой временный или вечный бан.
+
+### 3. Временный бан
+
+**Общественное влияние**: Серьёзное нарушение стандартов сообщества,
+включая продолжительное неуместное поведение.
+
+**Последствия**: Временный запрет (бан) на любое взаимодействие
+или публичное общение с сообществом на определенный период времени.
+На этот период не допускается публичное или личное взаимодействие с людьми,
+вовлеченными в инцидент, включая незапрошенное взаимодействие
+с теми, кто обеспечивает соблюдение Кодекса.
+Нарушение этих правил влечет за собой вечный бан.
+
+### 4. Вечный бан
+
+**Общественное влияние**: Демонстрация систематических нарушений стандартов сообщества,
+включая продолжающееся неуместное поведение, домогательство до отдельных лиц,
+или проявление агрессии либо пренебрежительного отношения к категориям лиц.
+
+**Последствия**: Вечный запрет на любое публичное взаимодействие с сообществом.
+
+## Атрибуция
+
+Данный Кодекс Поведения основан на [Кодекс Поведения участника][homepage],
+версии 2.0, доступной по адресу
+<https://www.contributor-covenant.org/version/2/0/code_of_conduct.html>.
+
+Принципы Воздействия в Сообществе были вдохновлены [Mozilla's code of conduct
+enforcement ladder](https://github.com/mozilla/diversity).

-The document has been moved [here](https://docs.victoriametrics.com/victoriametrics/contributing/).
+If you like VictoriaMetrics and want to contribute, then we need the following:
+
+- Filing issues and feature requests [here](https://github.com/VictoriaMetrics/VictoriaMetrics/issues).
+- Spreading a word about VictoriaMetrics: conference talks, articles, comments, experience sharing with colleagues.
+- Updating documentation.
+
+We are open to third-party pull requests provided they follow [KISS design principle](https://en.wikipedia.org/wiki/KISS_principle):
+
+- Prefer simple code and architecture.
+- Avoid complex abstractions.
+- Avoid magic code and fancy algorithms.
+- Avoid [big external dependencies](https://medium.com/@valyala/stripping-dependency-bloat-in-victoriametrics-docker-image-983fb5912b0d).
+- Minimize the number of moving parts in the distributed system.
+- Avoid automated decisions, which may hurt cluster availability, consistency or performance.
+
+Adhering `KISS` principle simplifies the resulting code and architecture, so it can be reviewed, understood and verified by many people.

-
-Logs generator for [VictoriaLogs](https://docs.victoriametrics.com/victorialogs/).
-
-## How to build vlogsgenerator?
-
-Run `make vlogsgenerator` from the repository root. This builds `bin/vlogsgenerator` binary.
-
-## How run vlogsgenerator?
-
-`vlogsgenerator` generates logs in [JSON line format](https://jsonlines.org/) suitable for the ingestion
-via [`/insert/jsonline` endpoint at VictoriaLogs](https://docs.victoriametrics.com/victorialogs/data-ingestion/#json-stream-api).
-
-By default it writes the generated logs into `stdout`. For example, the following command writes generated logs to `stdout`:
-
-```
-bin/vlogsgenerator
-```
-
-It is possible to redirect the generated logs to file. For example, the following command writes the generated logs to `logs.json` file:
-
-```
-bin/vlogsgenerator > logs.json
-```
-
-The generated logs at `logs.json` file can be inspected with the following command:
-
-```
-head logs.json | jq .
-```
-
-Below is an example output:
-
-```json

-
-The `run_id` field uniquely identifies every `vlogsgenerator` invocation.
-
-### How to write logs to VictoriaLogs?
-
-The generated logs can be written directly to VictoriaLogs by passing the address of [`/insert/jsonline` endpoint](https://docs.victoriametrics.com/victorialogs/data-ingestion/#json-stream-api)
-to `-addr` command-line flag. For example, the following command writes the generated logs to VictoriaLogs running at `localhost`:
-
-```
-bin/vlogsgenerator -addr=http://localhost:9428/insert/jsonline
-```
-
-### Configuration
-
-`vlogsgenerator` accepts various command-line flags, which can be used for configuring the number and the shape of the generated logs.
-These flags can be inspected by running `vlogsgenerator -help`. Below are the most interesting flags:
-
-* `-start` - starting timestamp for generating logs. Logs are evenly generated on the [`-start` ... `-end`] interval.
-* `-end` - ending timestamp for generating logs. Logs are evenly generated on the [`-start` ... `-end`] interval.
-* `-activeStreams` - the number of active [log streams](https://docs.victoriametrics.com/victorialogs/keyconcepts/#stream-fields) to generate.
-* `-logsPerStream` - the number of log entries to generate per each log stream. Log entries are evenly distributed on the [`-start` ... `-end`] interval.
-
-The total number of generated logs can be calculated as `-activeStreams` * `-logsPerStream`.
-
-For example, the following command generates `1_000_000` log entries on the time range `[2024-01-01 - 2024-02-01]` across `100`
-[log streams](https://docs.victoriametrics.com/victorialogs/keyconcepts/#stream-fields), where every logs stream contains `10_000` log entries,
-and writes them to `http://localhost:9428/insert/jsonline`:
-
-```
-bin/vlogsgenerator \
-  -start=2024-01-01 -end=2024-02-01 \
-  -activeStreams=100 \
-  -logsPerStream=10_000 \
-  -addr=http://localhost:9428/insert/jsonline
-```
-
-### Churn rate

-It is possible to generate churn rate for active [log streams](https://docs.victoriametrics.com/victorialogs/keyconcepts/#stream-fields)
-by specifying `-totalStreams` command-line flag bigger than `-activeStreams`. For example, the following command generates
-logs for `1000` total streams, while the number of active streams equals to `100`. This means that at every time there are logs for `100` streams,
-but these streams change over the given [`-start` ... `-end`] time range, so the total number of streams on the given time range becomes `1000`:
-
-```
-bin/vlogsgenerator \
-  -start=2024-01-01 -end=2024-02-01 \
-  -activeStreams=100 \
-  -totalStreams=1_000 \
-  -logsPerStream=10_000 \
-  -addr=http://localhost:9428/insert/jsonline
-```
-
-In this case the total number of generated logs equals to `-totalStreams` * `-logsPerStream` = `10_000_000`.
-
-### Benchmark tuning
-
-By default `vlogsgenerator` generates and writes logs by a single worker. This may limit the maximum data ingestion rate during benchmarks.
-The number of workers can be changed via `-workers` command-line flag. For example, the following command generates and writes logs with `16` workers:
-
-```
-bin/vlogsgenerator \
-  -start=2024-01-01 -end=2024-02-01 \
-  -activeStreams=100 \
-  -logsPerStream=10_000 \
-  -addr=http://localhost:9428/insert/jsonline \
-  -workers=16
-```
-
-### Output statistics
-
-Every 10 seconds `vlogsgenerator` writes statistics about the generated logs into `stderr`. The frequency of the generated statistics can be adjusted via `-statInterval` command-line flag.
-For example, the following command writes statistics every 2 seconds:
-
-```
-bin/vlogsgenerator \
-  -start=2024-01-01 -end=2024-02-01 \
-  -activeStreams=100 \
-  -logsPerStream=10_000 \
-  -addr=http://localhost:9428/insert/jsonline \
-  -statInterval=2s
-```
