We use bitbake to build software for our products. Bitbake fetches the latest sourcecode from various repositories before it start to build software.
Bitbake uses a receipes which tell bitbake what repository to use and how to build the url to access that repository.

Part of a receipe below:

HGNAME = "repogroup/reponame"

SRC_URI = "hg://;protocol=http;scmdata=keep;module=${HGNAME}"

This would work with our previous rhodecode version (4.12.4)

Last week I updated to rhodecode 4.15 and the fetching of repositories did not work anymore. Bitbake reported:

ERROR: Fetcher failure: Fetch command failed with exit code 255, output:
abort: HTTP Error 500: Internal Server Error

ERROR: Function failed: Fetcher failure for URL: 'hg://;protocol=http;scmdata=keep;module=repogroup/reponame'. Unable to fetch URL from any source.

The following error is from the vcssserver.log:

ProgrammingError: PATH_INFO does not begin with repo name: //repogroup/reponame (repogroup/reponame)

It seems like bitbake generates an url with an extra "/" > "//repogroup/reponame"

I removed the trailing "/" from the bitbake receipe and everythong worked fine again:

HGNAME = "repogroup/reponame"

SRC_URI = "hg://;protocol=http;scmdata=keep;module=${HGNAME}"

It looks like rhodecode became more strict with url formatting.
The problem is resolved with the change to the bitbake receipe but the behaviour of rhodecode definitely changed between 4.12 and 4.15.
And i think a 404 error would be more appropriate instead of a 500 server error.
