Dɛn ne Deadlog na ɔkwan bɛn so na ɛboa ma wɔsiesie Go deadlocks?

Deadlog yɛ open-source, ɛkame ayɛ sɛ drop-in a wɔde besi Go gyinapɛn sync.Mutex ananmu a ɛboa developers ma wohu na wɔhwehwɛ deadlocks wɔ bere koro mu applications mu. Ɛyɛ adwuma denam logging lock acquisition order na ɛkyerɛ circular dependencies a ɛma goroutines sɛn daa. Sɛ anka wobɛhwɛ akwan a wɔahyɛ no nwini no, wunya amanneɛbɔ a emu da hɔ a ɛkyerɛ apon a ɛrepere pɛpɛɛpɛ — ɛkora nnɔnhwerew pii a wode siesie nsaanodwuma wɔ Go codebases a ɛyɛ den bere koro mu.

Ɛbɛyɛ dɛn na mede Deadlog abɔ Go adwuma a ɛwɔ hɔ dada no mu?

Integration yɛ tẽẽ ɛfiri sɛ wɔayɛ Deadlog sɛ ɛkame ayɛ sɛ drop-in replacement. Wosesa sync.Mutex ne Deadlog mutex type wɔ wo code mu, mpɛn pii no ɛhwehwɛ sɛ wobɛsesa import kwan ne refactoring kakraa bi pɛ. Ma no nyɛ adwuma wɔ nkɔso ne sɔhwɛ mu, afei ma no nyɛ adwuma wɔ adwumayɛ mu na woakwati sɛ wobɛbɔ ka. Wɔ akuo a wɔhwɛ Go microservices pii so no, platforms te sɛ Mewayz de module 207 ma wɔ $19/mo a ɛbɛtumi ama deployment adwumayɛ ayɛ mmerɛ a ɛka debugging nnwinnadeɛ te sɛ Deadlog.

Deadlog no yɛ nea wɔahyɛ da ayɛ titiriw ama nkɔso ne staging atwa yɛn ho ahyia.

Dɛn ne nneɛma a ɛtaa de deadlocks ba wɔ Go mu, na mɛyɛ dɛn asiw ano?

Deadlocks wɔ Go mu taa firi lock nhyehyɛe a ɛnhyia, nested locks a wɔanya wɔ ntoatoasoɔ ahodoɔ mu, anaa goroutines a ɛretwɛn wɔ channels a ɛnnya values da.
