I have: SRC_URI="https://cgwb.nci.nih.gov/cgi-bin/bambino?download_bambino_jar=core https://cgwb.nci.nih.gov/cgi-bin/bambino?download_bambino_jar=bundle" If emerge would call wget with an extra --content-disposition it would save the downloaded data under a proper filename. Or give us some variable into which one can inject some evil arguments to be passed down to wget, please. ;) From man page of wget: <quote> --content-disposition If this is set to on, experimental (not fully-functional) support for "Content-Disposition" headers is enabled. This can currently result in extra round-trips to the server for a "HEAD" request, and is known to suffer from a few bugs, which is why it is not currently enabled by default. This option is useful for some file-downloading CGI programs that use "Content-Disposition" headers to describe what the name of a downloaded file should be. </quote> wget --no-check-certificate --content-disposition https://cgwb.nci.nih.gov/cgi-bin/bambino?download_bambino_jar=core (writes to bambino_core_1.02.jar) wget --no-check-certificate --content-disposition https://cgwb.nci.nih.gov/cgi-bin/bambino?download_bambino_jar=bundle (writes to bambino_bundle_1.02.jar)
Are you aware of SRC_URI arrows which have been supported since EAPI 2? For example: EAPI=2 SRC_URI="https://cgwb.nci.nih.gov/cgi-bin/bambino?download_bambino_jar=core -> bambino_core_1.02.jar https://cgwb.nci.nih.gov/cgi-bin/bambino?download_bambino_jar=bundle -> bambino_bundle_1.02.jar"
No, did not know, thanks. ;-)

Umm, I hoped you keep this bug open as a feature request. If the wget call would be improved then one would need not the "->" trick in many cases and thing would work out of the box. It is just one http(s) connection extra. Anyways, I tend to object as the trick is not documented here anyways: ;) http://devmanual.gentoo.org/ebuild-writing/variables/index.html#src_uri
I don't think we should. Fetching is enough of a mess already without adding convolutions for silly upstreams, especially since arrows solve the problem.

I see a couple of problems with this approach: 1) Unlike SRC_URI arrows, the local filename cannot be derived from the SRC_URI metadata in a simple way. This is a problem since both the ebuild code and the package manager need this filename to be precisely defined. 2) If behavior of a remote server determines the local filename, then the filename is somewhat difficult to predict. It requires some sort of IPC between the fetcher program (wget) and the package manager, in order to communicate the local filename. > Anyways, I tend to object as the trick is not documented here anyways: ;) > http://devmanual.gentoo.org/ebuild-writing/variables/index.html#src_uri You can file a new bug for that and assign to qa@gentoo.org.

But we want to know the filename before we start to fetch it. Multiple packages are allowed to have the same filename in their downloads list.
