ports-mgmt Manage your ports without external databases or languages
Expand on an idea provided by mandree@ to use 'pkg_version -I' to quickly
check what ports are out of date, and incorporate that check into the
--index option. Feedback from users seems to indicate that this is what
they expected the option to do anyway, so the minor change to the feature
does not seem to be a POLA violation, especially since INDEX support is
still relatively new. Add the --index-first option to do what --index used
to do in case anyone cares.
1. Add more error checking for incompatible command line options.
Add a new cross_idx() to handle checking the 3 --index* options, and
consolidate some of the old tests that were all relative to -G.
2. We want to test the .bz2 version of INDEX to see if it's newer, and
unzip it if it is.
3. For -o mode:
Going back a long ways upg_port was (ab)used to indicate the currently
installed version of the old port for -o. Originally this was safe since
it's very rare to have the new port installed already, and it saved a
little bit of code complexity. However, as more and more features were
added that utilized the value of upg_port it became increasingly
unsafe. Particularly, at this time there are 2 related bugs manifest.
First the wrong information appears in the confirm list (upgrade of
the old port vs. install of the new) and parsing the old port
directory. The latter was (mostly) harmless, although in the case of
an old port directory being DEPRECATED this resulted in a fatal error
when trying to upgrade.
So, make the following changes:
a. Make upg_port an installed version of the new port, if it exists.
b. Introduce ro_upg_port for the existing version of the old port.
c. Factor out some code that was related to how to handle lack of an
installed version of the old port (since now that's done higher up).
d. In the stage after the build of the new port and before pkg_delete
of the old port test for upg_port OR ro_upg_port and run the various
features (lib backup for -w, pkg_delete, etc.) as needed for both.
e. In install_failed() notify the user about the backup port for the old
f. I discovered in regression testing that invoking -o for MOVED
ports that we get to as dependencies was working, but the code to
automatically invoke -o for a parent port was broken. The problem is
that we can't just exec a new version if we're the parent, we have to
cleanly shut down background fetches and other processes, delete temp
files, etc. So split the parts of safe_exit() that relate to these
elements into their own function, parent_exit(), and call it both
from safe_exit() and when exec'ing a new version for -o in this case.
4. Add error checking to pm_mktemp, and the stray mktemp call. According
to a private report from a user it can actually fail.
5. Add error-checking to parse_index() so that if we don't find a line for
the port we return an error code; check for the error in the callers.
6. Improve the handling of various situations where there is no ORIGIN
recorded in the +CONTENTS file. This is almost always an error in the
package building process, and therefore usually needs to be flagged and
handled as an error. There are (at least) 2 situations where it may not
be an error; bsdpan ports, and when the user has added an +IGNOREME file
(usually for 3rd party packages).
a. Add code to origin_from_pdb() that tests to see that grep returned
something, echos the result as before, then also returns successfully
* If the port is a bsdpan port, return with an error code but let the
caller handle the reporting as appropriate.
* If there is no ORIGIN but there is an +IGNOREME file don't report
the error unless we're using -v, then also report that the
+IGNOREME file is there. Either way, return with an error code.
* If there is no ORIGIN, and no +IGNOREME file, report the error and
return with an error code.
b. In several places this allows several lines of code where the
function is called to be collapsed into:
origin=`origin_from_pdb $iport` || continue
c. In the main body where we parse the command line for what to work on
convert the code that was individually testing the various conditions
that are now handled in origin_from_pdb() to simply parse the return
codes with a case statement.
In the common case (there is an ORIGIN in +CONTENTS) this is almost
certainly a minor optimization since the error handling code in
origin_from_pdb() is never reached, and several places where things
like "is it a bsdpan port?" and other error handling have been removed.
7. In check_for move some local variables down into the block where they
