Subject [jira] Commented: (COUCHDB-1005) Rewriting to a URL with 2 replacements fails
Date Mon, 03 Jan 2011 20:17:45 GMT

    [ https://issues.apache.org/jira/browse/COUCHDB-1005?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12976932#action_12976932
] 

Sam Bisbee commented on COUCHDB-1005:
-------------------------------------

While I'm all for a more feature rich rewrite/regex engine after benchmarking, I don't think
it's needed to fulfill the needs of this ticket. The current implementation already allows
for URLs to be built using multiple variables, as long as they are separated by a slash. All
that needs to happen is to have that restriction lifted - allow >=0 characters as separators.
Even allowing >=1 character would be a huge improvement, because it would allow document
ids to be built, while we currently can only build URLs.

Of course, I don't know the internals well enough, but an educated guess/feeling says that
this shouldn't be too tricky. Or am I missing a piece of complexity?

Cheers.

> When I pull two variables out of a URL and drop them into the target, the target URL
breaks. However, it appears that the variables are being captured appropriately.
> This couch was built from source on Ubuntu 10.04 and is running a default config.
> Unexpected Results
> ----------------------------
> Assuming that we're querying the _rewrite handler with /foo/bar
> { "from": "/:user/:plugin", "to": "../../:user-:plugin"} will result in /db/undefined?user=foo&plugin=bar
> { "from": "/:user/:plugin", "to": "../../:user :plugin"} will result in /db/undefined?user=foo&plugin=bar
> { "from": "/:user/:plugin", "to": "../../:user"} will CORRECTLY result in /db/foo?user=foo&plugin=bar
> Expected Results
> ------------------------
> { "from": "/:user/:plugin", "to": "../../:user-:plugin"} should result in /db/foo-bar?user=foo&plugin=bar
> { "from": "/:user/:plugin", "to": "../../:user :plugin"} will result in /db/foo bar?user=foo&plugin=bar
