2014-06-29Calculate approx gas bill on divesGravatar Anton Lundin
This uses a bit of naive gas computations to figure out how much of different base gases you used up on the dives the statistics is done for. It's quite useful to get a minimum line about how big your gas bill is going to be after a dive trip. Signed-off-by: Anton Lundin <glance@acc.umu.se> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2014-06-01Remove is_air() and convert its users to gasmixGravatar Dirk Hohndel
Also make gasname() and get_gas_string() global functions (which allows us to delete code elsewhere). Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2014-05-20Migrate code to for_each_dive and for_each_dcGravatar Anton Lundin

2014-05-20Consistently use for_each_dive (and use it correctly)Gravatar Dirk Hohndel
The way the macro is written there is no need to test the dive against NULL before dereferencing. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2014-05-13Do not check for null before free.Gravatar Tomaz Canabrava
C specs says that we can safelly free a NULL pointer, so there's no reason to check if it's null before freeing it. Signed-off-by: Tomaz Canabrava <tomaz.canabrava@intel.com> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2014-04-26Don't calculate SAC-rates for negative pressure changesGravatar Linus Torvalds
They happen - maybe the cylinder actually warmed up, or maybe the user entered just a ending pressure without a starting pressure. Regardless, just ignore cylinder pressure changes that go up. Also ignore cylinders with a zero ending pressure: that's really a *missing* pressure rather than an actual zero pressure. As Dirk says, the scuba regulators don't even work without a healthy positive pressure differential, so even when you breathe down a tank to "empty", it won't be at zero pressure (this is true even with gauge pressure, where zero means "atmospheric pressure").

2014-02-27Massive automated whitespace cleanupGravatar Dirk Hohndel
I know everyone will hate it. Go ahead. Complain. Call me names. At least now things are consistent and reproducible. If you want changes, have your complaint come with a patch to scripts/whitespace.pl so that we can automate it. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2014-01-16Convert the C code to using stdbool and true/falseGravatar Anton Lundin
Earlier we converted the C++ code to using true/false, and this converts the C code to using the same style. We already depended on stdbool.h in subsurfacestartup.[ch], and we build with -std=gnu99 so nobody could build subsurface without a c99 compiler.

2013-12-11Close warning first might be garbageGravatar Anton Lundin
First might be garbage if get_ranges would be called when dive_table.nr == 0. This would rather signal that something else is broken, but at least we shouldn't make it worse. Signed-off-by: Anton Lundin <glance@acc.umu.se> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

2013-11-29Rewrite is_gas_used to use get_cylinder_indexGravatar Anton Lundin
get_cylinder_index implements a algorithm to map gaschange events to gas idx. This is a bit clumsy to use it to map if a gas idx have bin used, but its consistent with other parts. Signed-off-by: Anton Lundin <glance@acc.umu.se> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2013-11-27Only return gas volumes for gases usedGravatar Anton Lundin
We check in get_gaslist is_gas_used, so if were going to be consistent about what we return from get_gaslist and in get_gas_used, only return gas volumes that we actually consumed during the dive.

2013-10-20Get rid of compiler warning on format stringsGravatar Miika Turkia

2013-10-09Next step towards working translationsGravatar Dirk Hohndel
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.

2013-10-06Make is_gas_used work with SAMPLE_EVENT_GASCHANGEGravatar Anton Lundin

2013-10-06First steps towards removing glib dependenciesGravatar Dirk Hohndel
- remove the build flags and libraries from the Makefile / Configure.mk - remove the glib types (gboolean, gchar, gint64, gint) - comment out / hack around gettext - replace the glib file helper functions - replace g_ascii_strtod - replace g_build_filename - use environment variables instead of g_get_home_dir() & g_get_user_name() - comment out GPS string parsing (uses glib utf8 macros) This needs massive cleanup, but it's a snapshot of what I have right now, in case people want to look at it.

2013-05-17Merge branch 'Qt'Gravatar Dirk Hohndel
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.

Establish some useful helpers and use them when updating the values. One of the helpers (from statistics.c) puzzlingly doesn't link - so that's ifdefed out. Also had to re-arrange the settings reading code (it came too late) and to extract the expanding code of the top dive from the settings reading code (as it had no business being there to begin with).

2013-04-09Store the tag names instead of an opaque numberGravatar Dirk Hohndel
And as we need the names for that, simplify the way we show the tags in the Dive Info tab (and mark them for translation while we are at it). In the process I renamed the constants to DTAG_ from DTYPE_ (and made their nature as being just bits more obvious). Also mark the box on the Info tab "Dive Tags", not "Dive Type".

2013-04-09Add dive tags and support invalid divesGravatar Ďoďo
This started out as a way to keep dives in the dive list but being able to mark them as 'invalid' so they wouldn't be visible (with an option to disable that feature). Now it supports an (at this point, fixed) set of tags that can be assigned to a dive with 'invalid' being just one of them (but one that is special as it gets some additional support for hiding such dive and marking dives as (in)valid from the divelist).

2013-04-07Fix some of the gcc-4.8 warningsGravatar Dirk Hohndel
Most of the warnings are IMHO false positives: e.g.: an enum variable is initialized in a switch statement that has a case for each possible enum value - yet gcc 4.8 warns that it could be used uninitialized; or: two variables are initialized together in the code - second one of them is previously initialized to -1 at declaration time, both are initialized in an if (second one == -1) clause - so they are guaranteed to both be initialized... I did not "fix" those as the code is actually correct. But there are three spots where it catches things that could indeed go wrong (with odd input data in one of them). This commit also adds a check to only call g_type_init() for older versions of glib as in newer ones it is deprecated. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

2013-03-03Try to capture some more potential buffer overflows caused by localizationGravatar Dirk Hohndel
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.

2013-02-25Take incompressibility of gas into account at higher pressuresGravatar Linus Torvalds
This creates a helper function called "gas_volume()" that takes the cylinder and a particular pressure, and returns the estimated volume of the gas at surface pressure, including proper approximation of the incompressibility of gas. It very much is an approximation, but it's closer to reality than assuming a pure ideal gas.

This may look as a simple formatting change and won't make much sense to the C programmer. It is an actual bug fix in Subsurface for the target compiler, since it introduces bogus instructions.

2013-02-18Clear statistics and equipment when no dive is selectedGravatar Dirk Hohndel
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. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

2013-02-09Move duration to dive structure and replace accessor functionGravatar Dirk Hohndel
When starting on this quest to stop using the first divecomputer instead of data for the whole dive in commit eb73b5a528c8 ("Duration of a dive is the maximum duration from all divecomputers") I introduced an accessor function that calculates the dive duration on the fly as the maximum of the durations in the divecomputers. Since then Linus and I have added quite a few of the variables back to the dive data structure and it makes perfect sense to do the same thing for the duration as well and simply do the calculation once during fixup. This commit also replaces accesses to the first divecomputer in likely_same_dive to use the maxdepth and meandepth of the dive (those two slipped through the cracks in the previous commits, it seems).
