- tray.pl (zf): lower floor by another mm, leaving 3-4 mm of material
- tray.pl (vd): increase vial diameter by 0.1 mm to allow for vial
tolerance and material expansion. Also, working from the inside to the
outside (instead of plunging into uncut material first) decreased the
hole radius slightly.
- tray.pl (do_cols, do_circles): removed exclusion of the first column
radius after vial
tolerance,
- doit (GEN): corrected name of toolpath generator
- doit (rdata): fixed typo ("rdate" vs. "rdata")
- doit (Z): set Z depth here, to avoid manual depth adjustment
- doit: don't use cameo - we compensate for the tool size in tray.pl
- doit: increased feed rate from 2 mm/s to 4 mm/s
- doit: clearance is above top layer, so 5 mm are more than enough
- tray.pl (zf): increase floor depth from very conservative 15 mm to
17 mm
- tray.pl (zs): increase depth step from 2 mm to 2.5 mm to accelerate
milling
- tray.pl (mw): increase wall thickness from 2 mm to 2.5 mm in order to
enlarge gap between sides (was smaller than tool diameter)
- tray.pl (r1): stop 2 steps before the edge, since we have the outline
as another radius-like step
- tray.pl (do_col): account for tool radius
- tray.pl (do_circles): lift the tool after each disc, not only after
each column
- tray.pl (do_cols, do_circles): temporarily skip 1st column
- tray.pl (main): do circles before the outline, to reduce chatter when
cutting the outline
- tray.pl (main): since we're no longer using "cameo" here, don't print
directives for it
This doesn't work yet. In particular, going through "cameo" doesn't seem
the most convenient choice, since "cameo" requires paths to be closed,
which is something the paths we use here aren't. (Conceptually, thet are
closed, but the implementation skips some small segments.)

We define a cyclic dependency as the possibility (!) of the prerequisites
of a package X including a package that depends on X, and issue an error
if encountering such a situation.
Note that, if the dependencies of X can be resolved in a manner that does
not include the cyclic dependency, qpkg will still fail if it encounters
the cycle. Also note that qpkg (at least so far) does no perform an
exhaustive search to ferret out cyclic dependencies.
Furthermore, we don't consider that a cyclic dependency may not necessarily
imply a real life problem. E.g., if a package A contains elements X and
Y, with X needing package B, and the content of package B has a run-time
dependency on Y, the cyclic dependency between A and B would not exist
when considering its constituents. Since we don't have this information, we
just err on the side of caution.
- qpkg.h (enum flags): divide flags into categories (parse-time and
run-time) and add flag QPKG_ADDING to mark packets whose dependencies we
are processing
- prereq.c (resolve, prereq): track which packages we're tentatively
considering for installation and detect cyclic dependencies
- test/cyclic: regression test for detection of cyclic dependencies
- TODO: updated with recent changes
Until now, when considering adding a package, we processed its
dependencies after completing the current list of dependencies. E.g.,
if we had a package A that depended on B and C, B depended on D, and C
depended on E, then the sequence would have been A, B, C, ...
We now process the dependencies of a package immediately after
considering the package, so the sequence above would become A, B, D,
C, ...
The advantage of the new order is that it becomes easier to follow the
dependency tree, which will be beneficial for loop detection and for
ordering packages by installation order.
- prereq.c (resolve): change prerequisite resolution order such that the
dependencies of the package being considered are processed immediately,
instead of deferring them until the end of the current dependency list
- prereq.c (prereq): we can now pass the list of dependencies directly,
without needing a list of lists element
- test/resorder: test resolution order
- gobble.c (gobble_buf): list_with_version reversed the order of the list
items. It makes the behaviour of later algorithms more intuitive if we
maintain the file order.
The original idea was to just copy "stack" (now called "installed") to
"best" when done. In this case, "best" would remain NULL if "install"
had no entries, which would then be interpreted as a failure to resolve
the prerequisites.
However, since we allocate a new list for "best" anyway, this concern
no longer exists, and we can also get rid of the contorted mechanism
that was designed to work around this problem. (It was never put into
action because I wanted to make a regression test for it first.)
- prereq.c (prereq): removed commented-out and nonsensical avoidance of
false error
- test/prereq: added test case with no prerequisite
- Makefile (test, tests, valgrind): new targets to run regression tests

- gobble.c (finish_pkg): check that the package has a version
- gobble.c (finish_pkg): check that the package has an architecture
- gobble.c (finish_pkg): check that the package either has a file name or
is installed
- qpkg.h (struct pkg): added "arch" field for the architecture
- gobble.c (gobble_buf): record the architecture
- gobble.c (gobble_buf): fail if trying to set the file name twice
- qpkg.c (main): initialize trees before doing anything else, so that the
argument processing stays together
- id.h, id.c (make_id): return a "struct jrb *", so that we have access to
key and value
- gobble.c (ID, gobble_buf): adapt to above change

of awkwardly regenerating it via pkg->id->jrb
- id.h, id.c (first_id, next_id): removed
- qpkg.c (list_all_packages): use jrb_first/jrb_next instead of
first_id/next_id

if building for uClibc
