I've noticed the following problem.
If a distfile is updated by a distributor without renaming it (so that checksum
and possibly size change), then more often than not the port build system would
fail to fetch the distfile.
An example:
...
=> SHA256 Checksum mismatch for
eclipse/javax.servlet.jsp_2.0.0.v200806031607.jar.
...
=> javax.servlet.jsp_2.0.0.v200806031607.jar doesn't seem to exist in
/usr/ports/distfiles/eclipse.
=> Attempting to fetch
http://download.eclipse.org/tools/orbit/downloads/drops/R20100519200754/bundles/javax.servlet.jsp_2.0.0.v200806031607.jar
fetch:
http://download.eclipse.org/tools/orbit/downloads/drops/R20100519200754/bundles/javax.servlet.jsp_2.0.0.v200806031607.jar:
Requested Range Not Satisfiable
=> Attempting to fetch
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/distfiles/eclipse/javax.servlet.jsp_2.0.0.v200806031607.jar
fetch:
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/distfiles/eclipse/javax.servlet.jsp_2.0.0.v200806031607.jar:
size mismatch: expected 63889, actual 62707
=> Couldn't fetch it - please try to retrieve this
=> port manually into /usr/ports/distfiles/eclipse and try again.
*** Error code 1
I think that this happens because the old version of the distfile is still
present in download target location and fetch(1) thinks that it has a partially
downloaded file and tries to be smart.
The following patch simply tries to remove the stale distfile before calling
fetch. Maybe there is a smarter way about this, like e.g. passing some option
to fetch.
