NotaR fora do ar 06/09/2024 #146

Open Lobz opened 1 week ago

Lobz commented 1 week ago

NotaR foi notificado fopra do ar pelo discord:

John Davis — 09/06/2024 7:54 PM Boa noite pessoal, alguém mais está tendo dificuldades para acessar o notaR ? Não consigo acessar a plataforma desde a tarde.

E ficou fora do ar até segunda de manhã (09/09) quando @adalardo reiniciou o serviço com deploy.sh. Precisamos averiguar

  1. Por que o serviço caiu?
  2. Por que o serviço não voltou automaticamente?

Usando artisan tinker, confirmei que o usuário 362 não tem nota para o exercício 13. (Obs: adicionar logging para notas e não apenas submissões, para facilitar o troubleshooting)

Na pasta temp, onde ficam os arquivos com os códigos, encontrei uma submissão do mesmo dia (certamente o arquivo não foi deletado devido a um crash do serviço). O código era o seguinte:

linhas<-25
colunas<-15
dist<-25*15
desvio<-sqrt(3.6)
distribuição<-rnorm(dist,10,desvio)
distribuição

matNorm <-matrix(distribuição, nrow = linhas, ncol = colunas, byrow = T, 
                 dimnames = list(paste("l",1:25, sep = ""), paste("c", 1:15, sep = "")))  

matNorm
edit(matNorm)

Suspeito que o crash esteja relacionado com o uso da função edit, que abre uma nova janela.

O journalctl do docker para o dia 6, 19h47 contém apenas isto:

Testei submeter um código com edit, e o resultado é que o container r abre um vim e fica esperando o input para sempre. Reiniciar o serviço resolve o problema.
