Comments: 11

Distributed Systems

These applications were built with the objective of studding a distributed systems using the most recent technics. The main ideia was create all applications using: Clean Architecture, Distributed Logging, Distributed Tracing, Async Communication, CI/CD, Loading Balancer, Auto scale, etc. The system context was a simple book store.

Application Map

- Responsible for create a user, authenticate a user and communicate with the others applications using gRPC.
- Used Technologies:
  - Built in GoLang
  - PostgreSQL
  - RabbitMQ Publisher
  - gRPC client
  - Cache in some Routes
Inventory ms: Built in RustLang
- Responsible for story and management all books.
- Used Technologies:
  - Built in RustLang
  - MongoDB
  - gRPC Server
  - RabbitMQ Subscriber
Purchase ms: Built in NodeJs
- Responsible to management the purchases and the payments
- Used Technologies:

build(deps): bump regex from 1.5.4 to 1.5.5 in /inventory_ms
Bumps regex from 1.5.4 to 1.5.5.

Changelog

Sourced from regex's changelog.

1.5.5 (2022-03-08)

This releases fixes a security bug in the regex compiler. This bug permits a vector for a denial-of-service attack in cases where the regex being compiled is untrusted. There are no known problems where the regex is itself trusted, including in cases of untrusted haystacks.

SECURITY #GHSA-m5pq-gvj9-9vr8: Fixes a bug in the regex compiler where empty sub-expressions subverted the existing mitigations in place to enforce a size limit on compiled regexes. The Rust Security Response WG published an advisory about this: https://groups.google.com/g/rustlang-security-announcements/c/NcNNL1Jq7Yw
