2013-05-06Start populating the maintab Dive Info widgetGravatar Dirk Hohndel
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).

2013-04-14Separate Gtk related code from core logic: statisticsGravatar Dirk Hohndel
Fairly straight forward, so far just one tiny bit of code restructuring, everything else separated cleanly. Added statistics-gtk.c and statistics.h This should make no difference to functionality. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
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>
2013-03-28Use the new get_o2()/get_he() helper functions more widelyGravatar Linus Torvalds
They do the "02=0 means air" thing autmatically, and make for less typing. So use them more widely in places that looked up the o2 and he permille values of a gasmix. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> 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.

2013-02-23statistics.c: Fix a potential compiler bug triggered in gcc 3.4.5Gravatar Lubomir I. Ivanov
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. The "month" variable ends up being incremented up to 72 for a single "month++" call (if inside offset brackets). gcc -v Configured with: ../gcc-3.4.5-20060117-3/configure --with-gcc --with-gnu-ld --with-gnu-as --host=mingw32 --target=mingw32 --prefix=/mingw --enable-threads --disable-nls --enable-languages=c,c++,f77,ada,objc,java --disable-win32-registry --disable-shared --enable-sjlj-exceptions --enable-libgcj --disable-java-awt --without-x --enable-java-gc=boehm --disable-libgcj-debug --enable-interpreter --enable-hash-synchronization --enable-libstdcxx-debug Thread model: win32 gcc version 3.4.5 (mingw-vista special r3) OS: Windows 7 [6.1.7601] - x64 Better explained here: http://lists.hohndel.org/pipermail/subsurface/2013-February/003967.html Signed-off-by: Lubomir I.

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>
2013-02-14Better handling of manually edited air temperatureGravatar Dirk Hohndel
We now load and save this in the XML file, we do the right thing when merging dives and show the edited air temperature in the Dive Info notebook when a divecomputer doesn't have an air temperature. 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). Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2013-02-09Add a meandepth to the dive structureGravatar Dirk Hohndel
This is currently only used in one place (in statistics.c), but it certainly is consistent with the other recent changes to avoid using only the first divecomputer when trying to make statements about a dive. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2013-02-09Show the actice divecomputer's data in the Info notebookGravatar Dirk Hohndel
While the profile switched between different divecomputers, the Dive Info notebook always showed either information from the first divecomputer or (with some of the recent changes) information that had been collected from all divecomputers and somehow consolidated for the dive. With this commit we now show the data from the same divecomputer that is also shown in the profile (which means if some data is available from one of the divecomputers and not from another that will be correctly reflected in the Dive Info notebook as the user cycles through the divecomputers. This does beg the question if we should have some kind of "best data available, considering all divecomputers" mode - but that's definitely not something I'll tackle prior to 3.0. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2013-02-08Add maxdepth back to the dive structureGravatar Dirk Hohndel
Populate during dive fixup as the maximum depth shown by all the divecomputers. Use this value (instead of the one in the first divecomputer) in printing, statistics, etc. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2013-02-08Improve calculation of maxtemp and mintemp of diveGravatar Dirk Hohndel
The existing code only populated the maxtemp based on the samples of a dive and then in statistics.c checked if there was no such temperature and replaced it with the water temperature of the first divecomputer. It makes much more sense to add the water temperature information in every divecomputer to the min / max calculation during the dive fixup phase. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2013-02-08Simplify/clarify the get_surface_pressure_in_mbar() functionGravatar Linus Torvalds
Instead of maintaining a rolling average and re-calculating it at each stage, just calculate the surface_pressure average the natural way: as the sum divided by the number of entries. This results in a single rounding, rather than doing rounding multiple times and possibly rounding wrong as a result. Not that we care all that deeply about the LSB of the mbar value, but the code is simpler and more obvious this way too.

2013-02-09Clean up the handling of surface pressureGravatar Dirk Hohndel
There are two ways to look at surface pressure. One is to say "what was the surface pressure during that dive?" - in that case we now return an average over the pressure reported by the different divecomputers (or the standard 1013mbar if none reported any). Or you want to do specific calculations for a specific divecomputer - in which case we access only the pressure reported by THAT divecomputer, if present (and fall back to the previous case, otherwise). We still have lots of places in Subsurface that only act on the first divecomputer. As a side effect of this change we now make this more obvious as we in those cases pass a pointer to the first divecomputer explicitly to the calculations. Either way, this commit should prevent us from ever mistakenly basing our calculations on a surface pressure of 0 (which is the initial bug in deco.c that triggered all this). Similar changes need to be made for other elements that we currently only use from the first divecomputer, i.e., salinity. Reported-by: Robert C.

2013-02-08Duration of a dive is the maximum duration from all divecomputersGravatar Dirk Hohndel
So far we always used the duration of the first divecomputer. The same fix needs to be done for some of the other calculations that always use the first divecomputer. This commit also removes some obsolete code from the webservice merging. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

2013-01-30Massive cleanupGravatar Dirk Hohndel
Mostly coding style and whitespace changes plus making lots of functions static that have no need to be extern. This also helped find a bit of code that is actually no longer used. This should have absolutely no functional impact - all changes should be purely cosmetic. But it removes a bunch of lines of code and makes the rest easier to read.

2013-01-28Make subsurface compile with -DGSEAL_ENABLEGravatar Linus Torvalds
This forces us to use the proper gtk accessor functions. It may not be worth it if people actually do the Qt conversion, but if we want to try gtk3 at some point, this might help. 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.

2013-01-23Move more dive computer filled data to the divecomputer structureGravatar Linus Torvalds
This moves the fields 'duration', 'surfacetime', 'maxdepth', 'meandepth', 'airtemp', 'watertemp', 'salinity' and 'surface_pressure' to the per-divecomputer data structure. They are filled in by the dive computer, and normally not edited. NOTE! All actual *use* of this data was then changed from dive->field to dive->dc.field programmatically with a shell-script and sed, and the result then edited for details. So while the XML save and restore code has been updated, all the displaying etc will currently always just show the first dive computer entry.

2013-01-14Centralising and redefining values as integersGravatar Jan Schubert
This patch centralizes the definition for surface pressure, oxygen in air, (re)defines all such values as plain integers and adapts calculations. It eliminates 11 (!) occurrences of definitions for surface pressure and also a few for oxygen in air. It also rewrites the calculation for EAD, END and EADD using the new definitons, harmonizing it for OC and CC and fixes a bug for EADD OC calculation. And finally it removes the unneeded variable entry_ead in gtk-gui.c. Jan Signed-off-by: Jan Schubert <Jan.Schubert@GMX.li> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

If all selected dives appear to have numbers that make sense, assemble a string that lists the selected dives (and try to be smart about finding ranges) and display those in the frame of the statistics widget.

2012-11-11Fix average temperature statisticsGravatar Linus Torvalds
We generate the average temperature statistics by adding up the (converted to user unites - not in millikelvin) temperatures and then dividing by the number of dives we've added up over. HOWEVER. We did that summing of the temperatures into an integer variable, even though the converted temperatures are floating point. So things got rounded down to integers and the average temperature was just bogus (although reasonably close). We could do the summing of the temperatures in millikelvin and only doing the conversion to the user at the very end. But the smaller patch is to just change the accumulator to a double value.

2012-10-28Add support for visibility tracking and allow manual entry air tempGravatar Dirk Hohndel
Turns out we had a data field for visibility as a length unit - but never used it. I can never guess how much visibility we actually had on a dive - but I think most everyone can assign a rating between abysmal (zero stars, "I couldn't read my dive computer even right in front of my mask" - trust me, I had some of those dives) to amazing ("five stars, I could see farther than I though possible" - and I had one or two of those, too). So I changed this to an integer and am re-using the star infrastructure we have for the overall dive rating. When displaying this I was dismayed that we are running out of space in the "Dive Notes" notbook. So I moved this to the "Dive Info" notebook. This is not consistent and not logical. I think we need to revisit the notebooks and think about what we want to display where. While adding the infrastructure to manually enter the visibility I went ahead and added the ability to manually enter the air temperature as well (that was one of the things missing in the previous commit).

2012-10-28Display air temperature in the info notebook pageGravatar Dirk Hohndel

2012-10-17Handle dates and a "calculated plural" in translationsGravatar Dirk Hohndel
This looks like a massive commit mainly because of the line number changes in the .po files. That sadly hides what really happened here: - the places where we manually build dates have now been localized - the one place where we did the English "calculated plural" has been modified so that it now can be correctly translated (in English this just adds an 's' to the noun if the number is != 1 - in other languages this tends to be much more complicated) I then updated the two German translations to take advantage of the new constructs. And while I was at it, I changed the translation Trip->Gruppe to Trip->Reise as that seemed much more appropriate. I also fixed another error in the German translation where I translated "dive time" as "Startzeit" - but in the context it was "Dauer". Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

2012-10-14Improve translationsGravatar Dirk Hohndel
- fix two missing strings in equipment.c (thanks to Tommi Saviranta for pointing this out) - add context for the translations of the Yearly/monthly statistics. The code for this ended up being incredibly ugly, but the gettext infrastructure really clashed with the way this is implemented. What I have now at least works (tested with the German translation) - merge the new strings into all the po files. The non-German translations need to be updated. Make sure you remove the "# , fuzzy" lines or the current Makefile will ignore those additions. - some minor cleanup of the po files (many listed the wrong language, all of them copied my incorrect use of PACKAGE (instead of saying "Subsurface"). Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2012-10-11Conversion to gettext to allow localizationGravatar Dirk Hohndel
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.

2012-09-11Display yearly/monthly statisticsGravatar Miika Turkia
Display yearly statistics in a statistics window with option to expand the viewing on monthly level. The amount of dives along with basic information like duration, depth, water temperature and air consumption is displayed in yearly and monthly level. Thus you are able to compare e.g. development of air consumption or diving activity from year to year. Using already existing macro for splitting seconds into minutes:seconds. Moving repetitive code to a function (couldn't think of the suggested clever macro, but this should pretty much do the trick). Now the statistics are updated every time the process_all_dives function is called. It might make sense to actually verify the structures need to be re-allocated, but such optimization is currently not implemented.

The previous commit was a patch from Lubomir, which also had some whitespace fixes (to go with some new whitespace bugs to replace them) in it. I removed the whitespace changes from that patch (don't mix whitespace fixes with other fixes, unless they are on the same lines!) but decided to look for other whitespace issues, and this is the result. I left the non-C files alone, some of the spec and script files also have whitespace at the end of lines etc. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2012-08-21Add helper 'for_each_dive()' dive iteratorGravatar Linus Torvalds
It's an easy thing to do, but the for-loop ends up being pretty ugly, so hide it behind the macro. It would be even prettier with one of the (few) useful C99 features: local for-loop variables. However, gcc needs special command line options, and other compilers may not do it at all. So instead of doing #define for_each_dive(_x) \ for (int _i = 0; ((_x) = get_dive(_i)) != NULL; _i++) we require that the user declare the index iterator too, and the use syntax becomes for_each_dive(idx, dive) { ... use idx/dive here ... } And hey, maybe somebody actually will want to use the index, so maybe that's not all bad.
