A couple of these could clearly cause a crash just like the one fixed by
commit 00865f5a1e1a ("equipment.c: Fix potential buffer overflow in
size_data_funct()").
One would append user input to fixed length buffer without checking.
We were hardcoding the (correct) max path length in macos.c - replaced by
the actual OS constant.
But the vast majority are just extremely generous guesses how long
localized strings could possibly be.
Yes, this commit is likely leaning towards overkill. But we have now been
bitten by buffer overflow crashes twice that were caused by localization,
so I tried to go through all of the code and identify every possible
buffer that could be affected by this.

"output_units" was the user units, and "input_units" are the XML parsing

When we fill the cylinder information in an imperial unit world, a
working pressure of zero is a special case, and forces us to use the
actual physical size of the cylinder in liter, despite the fact that
we normally would use cuft.
However, we compare that value against zero in a 'double', and in
between going through the gtk spinbutton logic, the zero we have
filled in then gets read out as some very tiny epsilon value from the
gtk spinbuttons (typically in the 10**-317 range). This causes us to
think that the zero isn't actually a zero, because gtk has done odd
things with it.
Fix this by calculating the millibar value (as an integer) first, and
check that *integer* against zero. Any crazy epsilon values will have
been rounded away, and our logic works again.
There's a good reason why subsurface does everything using integers
(ie the afore-mentioned "convert to integer millibar" etc) and doesn't
use floating point for any core data structures, only for conversion.
FP rounding and inexact behavior can be really subtle.

Originally I used the colloquial term "bar" for the weight bar that you
can attach to a backplate (usually when diving twins in a tec
environment). This of course causes an odditity for translations as this
word "bar" is a homonym for the weight system and the pressure unit -
which throws off translations.
Instead of switching to a context-based translation I instead went with a
better term: "backplate weight". This of course now needs to be
translated, so I updated the .po files (and added German translations for
the two flavors of German).

This is just the first step - convert the string literals, try to catch
all the places where this isn't possible and the program needs to convert
string constants at runtime (those are the N_ macros).
Add a very rough first German localization so I can at least test what I
have done. Seriously, I have never used a localized OS, so I am certain
that I have many of the 'standard' translations wrong. Someone please take
over :-)
Major issues with this:
- right now it hardcodes the search path for the message catalog to be
./locale - that's of course bogus, but it works well while doing initial
testing. Once the tooling support is there we just should use the OS
default.
- even though de_DE defaults to ISO-8859-15 (or ISO-8859-1 - the internets
can't seem to agree) I went with UTF-8 as that is what Gtk appears to
want to use internally. ISO-8859-15 encoded .mo files create funny
looking artefacts instead of Umlaute.
- no support at all in the Makefile - I was hoping someone with more
experience in how to best set this up would contribute a good set of
Makefile rules - likely this will help fix the first issue in that it
will also install the .mo file(s) in the correct place(s)
For now simply run
msgfmt -c -o subsurface.mo deutsch.po
to create the subsurface.mo file and then move it to
./locale/de_DE.UTF-8/LC_MESSAGES/subsurface.mo
If you make changes to the sources and need to add new strings to be
translated, this is what seems to work (again, should be tooled through
the Makefile):
xgettext -o subsurface-new.pot -s -k_ -kN_ --add-comments="++GETTEXT" *.c
msgmerge -s -U po/deutsch.po subsurface-new.pot
If you do this PLEASE do one commit that just has the new msgid as
changes in line numbers create a TON of diff-noise. Do changes to
translations in a SEPARATE commit.

This is the same issue as 882cb159a4 (although now we

There is some sort of a GTK bug on Ubuntu 12.04 with GTK 2.24.10 that
prevents us from using the gtk_window_set_accept_focus() and similar
API to make the window behind fully inactive.
The proposed portable solution is to completely disable the background
window (NOTE: unless its the main window), disabling child controls
(gtk_widget_set_sensitive) and making the top window "transient for" or
putting it on top (gtk_window_set_transient_for).
Still we do not want to hide the background window titlebar with
gtk_window_set_decorated(), which makes it still clickable.

The "cylinders_equal()/copy_cylinders()" functions were buggered, and
only checked (and copied) the cylinder type. That was on purpose, since
you do want to be able to change the type of a cylinder without changing
the gasmix of the cylinder.
HOWEVER, the reverse is also true: you may want to change the gasmix of
a cylinder without changing the type.
So it's not that the type of the cylinder is special - it's that the
type and the gasmix should be considered separately.
Do that properly for the equipment editing case.

If we have no explicit cylinder info at all (it's normal air, no size or
working pressure information, and no beginning/end pressure information),
we don't save the cylinders in question because that would be redundant.
Such non-saved cylinders may still show up in the equipment list because
there may be implicit mention of them elsewhere, notably due to sample
data, so not saving them is the right thing to do - there is nothing to
save.
However, we missed one case: if there were other cylinders that *did* have
explicit information in it following such an uninteresting cylinder, we do
need to save the cylinder information for the useless case - if only in
order to be able to save the non-useless information for subsequent
cylinders.
This patch does that. Now, if you had an air-filled cylinder with no
information as your first cylinder, and a 51% nitrox as your second one,
it will save that information as
<cylinder />
<cylinder o2='51.0%' />
rather than dropping the cylinder information entirely.
This bug has been there for a long time, and was hidden by the fact that
normally you'd fill in cylinder descriptions etc after importing new
dives. It also used to be that we saved the cylinder beginning/end
pressure even if that was generated from the sample data, so if you
imported from a air-integrated computer and had samples for that cylinder,
we used to save it even though it was technically redundant.
We stopped saving redundant air sample information in commit 0089dd8819
("Don't save cylinder start/end pressures unless set by hand").

First: Don't check unsigned variables for < 0
This has been around for a while and we are lucky that while technically a

into a very large unsigned integer which then fails the > dive_table.nr
test. So it still gets a NULL returned. A bug? Yes. Critical? No.

Calling edit from the context menu creates a combined editing widget that
contains both dive info and equipment. When editing cylinders or
weightsystems from that widget and confirming those edits with OK those
changes were already committed to the current_dive - regardless on which
dive the user clicked. Worse, even when the user clicked Cancel in the
edit widget, any changes to the equipment stayed in effect.
This had especially confusing consequences when editing multiple dives.
As a workaround this commit adds a global edit_dive variable. This fake
dive is edited by the secondary editing widgets and if the user accepts
changes with OK then they are copied over to the current dive (or all
selected dives in multi dive editing mode).
Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
When figuring out which cylinders to change in a multi-dive edit, we
already ignored the beginning and end pressures. But it turns out to make
more sense to also ignore the Nitrox / Helium settings.
Imagine you do a number of dives - for some reason your dive computer
records the wrong cylinder size in the downloaded logfile (like my uemis
does all the time). Dives will likely have different Nitrox percentage,
but you should still be able to simply fix the cylinder size for all dives
at once.

This commit addresses two issues:
We now can add / edit / delete equipment from the edit dive dialog
We now can edit multiple dives at once
The latter feature has some interesting design constraints:
It picks the 'selected_dive' as the one to start the edit from - so if
this dive already has some information filled in, that information needs
to be overwritten before it is stored in all of the dives. Similarly, only
changes to the cylinders or weightsystems are recorded. Also, the notes
field is not editable in the multi dive edit mode (as that didn't seem
useful).
The workflow seems to work best if using the multi-edit right after
importing new dives from a dive computer. The user then can select all the
new dives and only needs to edit things like location, divemaster, buddy,
weights, etc. once.
This commit will create some obvious conflicts with the commit that adds

With this change, if the user adds a new weightsystem to a dive, on

So when the program imports a set of dives from the divecomputer and the
user starts editing them, once they enter the weight for the "integrated"
weightsystem the first time, for each of the consecutive dives that same
weight is the default once "integrated" is selected - which usually will

This makes the reference tanks ("struct tank_info") use a saner format
which specifies explicitly whether the size is in ml or cubic feet, and
whether the pressure is in psi or bar.
So instead of having magic rules ("size is in cuft if < 1000, otherwise
mliter"), just set the size explicitly:
{ "11.1 l", .ml = 11100 },
{ "AL80", .cuft = 80, .psi = 3000 },
and then the code can just convert to standard measurements without any
odd rules, and the initialization table becomes self-explanatory too.
