c539c8f861 Remove the .used member of the cylinder structure
Instead calculate this information on the fly, taking into account all
dive computers on the dive in questions.

There is one wrinkle to this - previously we abused the '.used' member to
make sure that a manually added cylinder didn't disappear the moment it
was added (think of the workflow: you add a cylinder, then you add a gas
change to that cylinder -> right after you add it it is unused and would
not be shown).

I am thinking that we might have to add the "manually_added" property to
the properties that we store in XML / git.

2a871d7fe5 Planner: track gas used even if we don't have a real cylinder
We tracked gas used by simulating a dive with a cylinder - but for that we
need a cylinder size and working pressure. If the user just enters a gas
but no cylinder data (likely in order to figure out how much gas is used
so that she then can pick a big enough cylinder), we didn't show any gas
consumption.

It kinda sucks to add another member to the cylinder structure, but this
seemed far more reasonable then some other, global structure that
independently tracks gas usage. This just seemed to make sense.

d054e8c457 Planner: track gas consumption in cylinders and samples
This commit is a little bigger than I usually prefer, but it's all
somewhat interconnected.

- we pass around the cylinders throughout the planning process and as we
  create the plan we calculate the gas consumption in every segment and
  track this both in the end pressure of the cylinder and over time in
  the samples
- because of that we no longer try to calculate the gas consumption after
  being done planning; we just use what we calculated along the way
- we also no longer add gases during the planning process - all gases
  have to come from the list of cylinders passed in (which makes sense
  as we should only use those gases that the user added in the UI or
  inherited from a the selected dive (when starting to plan with a dive
  already selected)

With this patch I think we are close do being able to move all of the
planning logic back into the planner.c code where it belongs. The one
issue that still bothers me is that we are juggling so many dive
structures and then keep copying content around. It seems like we should
be able to reduce that.

193d20c479 Next step towards working translations
This may seem like a really odd change - but with this change the Qt tools
can correctly parse the C files (and qt-gui.cpp) and get the context for
the translatable strings right.

It's not super-pretty (I'll admit that _("string literal") is much easier
on the eye than translate("gettextFromC", "string literal") ) but I think
this will be the price of success.

f3f7bf51fa Merge branch 'Qt'
After the 3.1 release it is time to shift the focus on the Qt effort - and
the best way to do this is to merge the changes in the Qt branch into
master.

Linus was extremely nice and did a merge for me. I decided to do my own
merge instead (which by accident actually based on a different version of
the Qt branch) and then used his merge to double check what I was doing.

I resolved a few things differently but overall what we did was very much
the same (and I say this with pride since Linus is a professional git
merger)

Here's his merge commit message:

    This is a rough and tumble merge of the Qt branch into 'master',
    trying to sort out the conflicts as best as I could.

    There were two major kinds of conflicts:

     - the Makefile changes, in particular the split of the single
       Makefile into Rules.mk and Configure.mk, along with the obvious Qt
       build changes themselves.

       Those changes conflicted with some of the updates done in mainline
       wrt "release" targets and some helper macros ($(NAME) etc).

       Resolved by largely taking the Qt branch versions, and then editing
       in the most obvious parts of the Makefile updates from mainline.

       NOTE! The script/get_version shell script was made to just fail
       silently on not finding a git repository, which avoided having to
       take some particularly ugly Makefile changes.

     - Various random updates in mainline to support things like dive tags.

       The conflicts were mainly to the gtk GUI parts, which obviously
       looked different afterwards.  I fixed things up to look like the
       newer code, but since the gtk files themselves are actually dead in
       the Qt branch, this is largely irrelevant.

       NOTE! This does *NOT* introduce the equivalent Qt functionality.
       The fields are there in the code now, but there's no Qt UI for the
       whole dive tag stuff etc.

    This seems to compile for me (although I have to force
    "QMAKE=qmake-qt4" on f19), and results in a Linux binary that seems to
    work, but it is otherwise largely untested.

92397a2bad Started the real code on the Qt Interface.
1 - Open File already open files, it tries to not break the Gtk version,
    but some methods on the GTK version still need to be called inside Qt
    because the code is too tight-coupled.

2 - Close file already close files, same comments for the open file dialog
    applies here.

3 - The code for adding new cylinders in the cylinder dialog is done,
    already works and it's integrated with the system.  There's a need to
    implement the edit and delete now, but it will be easyer since I'm
    starting to not get lost on the code.

4 - Some functions that were used to convert unities have been moved to
    convert.h ( can be changed later, put there because it's easyer to
    find something that converts in a convert.h =p ) because they were
    static functions that operated in the GTK version but I need those
    functions in the Qt version too.

8a5792d473 Manually add gas changes to a dive
Create a little widget that lists all the gases / tanks we know about and
allow the user to pick one of them.

Turns out that add_event only added events at the end of the list - but we
treat that list as chronologically sorted. So I fixed that little
mis-feature as well.

This does raise the question whether we need the inverse operation
(removing a gas change). And if there are other things that we should be
able to manually edit, now that we have the infrastructure for this neat
little context menu...

See #60 -- this doesn't address all of the issues mentioned there, but at
least deals with the 'headline' of the feature request...

0129192958 Try to capture some more potential buffer overflows caused by localization
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.

6ce4d29f49 Clear statistics and equipment when no dive is selected
This all seems very strange forward.

The reason for the check whether the stats_w widget has been populated is
that at the very beginning, when the UI is still being assembled, a first
call to switch_page() happens as the notebook pages are assembled. At that
point the stats_w widget is still empty which tells us that we aren't
ready to display anything.

This all came about because I was trying to explain on G+ what an
immense pain this all was to even figure out, if you don't actually know
gtk at all.  Google and the gtk migration guide are almost useless, and
the gtk2 documentation itself actually uses the fields directly without
any accessor functions in several places.

080bcc10fc gtk spinbuttons are crazy - fix possible divide-by-zero
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.

f4b6e53c4e Changed the term used for one of the default weight systems
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).

99846da77f Conversion to gettext to allow localization
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.

- no testing at all on Windows or Mac
  It builds on Windows :-)

so that we can free regardless.

45d6d6ac71 Keep the "Add/Edit Cylinder & Weight" dialogs on top
This is the same issue as 882cb159a4 (although now we
don't have "Import XML Files" within a dialog). It applies when
in the "Dive info" dialog.

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.
Make this change to older code in gtk-gui.c as well.

6ae67f96f8 Update cylinder info properly
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.

c4c636fb4f Fix missing save of (almost empty) cylinder information
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").

Removed start and end in save_cylinder_info(). These two variables are no
longer used.

d14932058f Fix some of the problems reported by cppcheck
Thanks to Christian for running the static code analysis tool against
subsurface...

There were some false positives, a few style issues that I'll ignore for
now, and two actual potential bugs.

First: Don't check unsigned variables for < 0

This has been around for a while and we are lucky that while technically a
bug it still works as expected. Passing a negative idx simply turns it
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.

Mismatched allocation and free

This is an actual bug that potentially could cause issues. We allocate
memory with malloc and free it with g_free. Not good.

By now the default file code seems quite matured, so in preparation for
2.0 we'll bring it back into master.

I made a few small clean-ups during the merge, but the merge itself is
very much straight forward.

b150c4fd41 Make sure all parts of the edit dialogs are using current_dive / edit_dive
While most of this problem was fixed in commit 18b3dca431a4 ("Fix a long
standing bug when editing dives"), it turns out that I missed a couple of
the equipment callbacks.

In the corner case of having an empty divelist (where therefore
current_dive == NULL) manually adding a dive and trying to add equipment
(cylinder or weightsystem) to it would crash subsurface as we were trying
to dereference current_dive.

41d3a11ee3 Fix a long standing bug when editing dives
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).
