Subject [jira] [Updated] (COUCHDB-1326) scanty error message when writing to uri_file fails
Date Mon, 31 Oct 2011 01:56:32 GMT

     [ https://issues.apache.org/jira/browse/COUCHDB-1326?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Rogutės Sparnuotos updated COUCHDB-1326:
----------------------------------------

    Attachment: 0001-A-more-useful-error-when-writing-to-uri_file-fails.patch

jan on irc said "patches welcome", so here is a bad one (don't know any Erlang):
1. I used Error2, because Error is defined up in scope and erlc complains about unsafe variables.
2. I used throw(), but it produces a trace and I think that Erlang traces scare
   users. Could one do
     echo "Failed to write uri_file %s, error %s."
     exit 1
   ?

> CouchDB crashes when it fails writing to uri_file (set from the [couchdb] section). The
error message is too vague to understand what's going on: "{{badmatch,{error,enoent}}". At
least the filename should be mentioned.
> P.S.
> I'd say it's all Erlang's fault, because file:write_file() doesn't report the file name
on errors.
