2013-02-02Add 'Save As' entry to context menu shown when right clicking on a diveGravatar Pierre-Yves Chibon
Something which is nice especially when asked on the list to share an interesting dive is the possibility to save just some dives into a file. This commit adds to the context menu shown with right-click the 'Save As' entry. This entry allows to save selected dives.

2013-02-01Move flag icon to include fileGravatar Dirk Hohndel
Just like with the satellite icon we are creating a pixdata structure for the flag. The Makefile cleanup in commit df6a9ddd8a21 ("Auto-generate C file dependencies, and make the build more quiet") removed the rules for generating the .h file by mistake (I hope). This adds a more generic rule back in and also makes sure that the data structures get more useful names. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2013-02-01When switching sort order, scroll the dive list to the current diveGravatar Linus Torvalds
Now that we actually seem to understand the whole notion of setting the active dive, let's take that code a bit further, and always scroll to it when we're introducing a new sort ordering. Sure, there may be other selected dives, but we have one primary (current) dive that we show the profile and dive data for, and when we switch sort order we probably want to see that dive in the dive list.

2013-01-31Make sure that the planned dive is selectedGravatar Dirk Hohndel
With the changes to the selection logic the selected_dive variable didn't get updated at the end of planning a dive. With an empty dive list that could cause selected_dive to be -1 which would subsequently cause a SIGSEGV when trying to edit the newly created dive. With this commit we use the shared go_to_iter() function and also make sure that selected_dive is set correctly.

2013-01-31Better algorithm to merge gps locations & locations names from webserviceGravatar Dirk Hohndel
This no longer abuses the dive merging code (which would leave stray "dives" behind if a gps fix couldn't be merged with any of the dives) and instead parses the gps fixes into a second table and then walks that table and tries to find matching dives. The code tries to be reasonably smart about this. If we have auto-generated GPS fixes at regular intervals, we look for a fix that is during a dive (that's likely when the boat where the phone is staying dry is more or less above the diver having fun). And if we have named entries (so the user typed in a location name) we try to match them in order to the dives that happened "that day" (where "that day" is about 6h before and after the timestamp of the gps fix). This commit also renames dive_has_location() to dive_has_gps_location() as the difference between if(!dive->location) and if(dives_has_location) is a bit too subtle...

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.

2013-01-30Make the selection logic more robustGravatar Dirk Hohndel
In commit 304526850c91 ("Don't deselect all dives on all selection "change" events") the handling of "selected_dive" is incorrect. We ended up with non-sensical values for the selected dive, including dives that Gtk didn't think were selected. This commit tries to be smart about what to do when the dive that we currently consider selected is unselected (we have this weird notion of many dives being selected, but one of them is shown in the profile and that is the "selected_dive"). As long as there are others selected, we pick one of them (first walking to earlier dives and if there are none that are selected, looking for a later dive) as the new selected dive. This appears to give us a rather intuitive behavior when playing with multiple selected dives. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2013-01-30Don't deselect all dives on all selection "change" eventsGravatar Linus Torvalds
gtk sends the selection change events all the time, for pretty much any "divelist changed - so selection changed". The expansion of a trip, the switch to a new model, yadda yadda. But we actually want selections to be sticky across these events, so we can't just forget all of our old selection state and repopulate it. So we re-introduce the "am I allowed to change this row" callback, which we used to use to create a list of every actual selection that was changed. But instead of remembering the list (and having the stale entries issue with that remembered list that caused problems), we now just use that as a "that *particular* selection cleared" event. So this callback works as the "which part of the visible, currently selected state got cleared" notifier, and handles unselection. Then, when the selection is over, we use the new model of "let's just traverse the list of things gtk thinks are selected" and use that to handle new selections in the visible state that gtk actually tracks well. So that logic handles the new selections. This way, dives that aren't visible to gtk don't ever get modified: gtk won't ask about them being selected or not, and gtk won't track them in its selection logic, so with this model their state never changes for us. gtk selections are annoying. They are simple for the case gtk knows about (ie they are *visually* selected in the GUI), but since we very much want to track selection across events that change the visual state, we need to have this insane "impedance match".

2013-01-28Rewrite gtk dive selection tracking logicGravatar Linus Torvalds
We used to generate a list of possibly changed selections using the gtk tree selection "selection function". But that's actually meant to just tell gtk whether an entry can be selected or not, and our list of possibly changed entries ended up being stale if the selection change was due to a list entry removal, for example. So rip out the old model entirely, and instead just walk the whole selection that gtk gives us on a selection "change" event. We throw all our old selections away when this happens, and just rebuild it all. This should fix the occasional internal gtklib-quartz assertion that Henrik is seeing. And it actually simplifies the code too.

2013-01-28Make dive planner more useful for closed circuit divingGravatar Dirk Hohndel
Add a sample at time 0 to allow for a pO2 from the start of the dive. Remember the last pO2 so it doesn't have to be repeated (and the right thing happens for the planned part of the dive). This still doesn't allow us to change the setpoint at a certain depth (which would be analogous to being able to switch to a certain gas at a certain depth in OC plans), but with this commit it's already usable. This commit also fixes a couple of small bugs in commit b8ee3de870fa ("Dive planning for closed circuit rebreather") where a pO2 of 1.1 was hardcoded in one place, throwing off all plan calculations and integer math was used to calculate a floating point value (leading to most pO2 values actually used being 1.0).

2013-01-23Fix setting of the dive_table.preexisting logicGravatar Linus Torvalds
The 'preexisting' value is used for downloading dives: we want to add new dives but, but then compare those new dives against the preexisting ones before we start sorting things and possibly merging them. However, the value was only updated sporadically, resulting in it having stale information in it. Which would cause problems particularly if you deleted dives, so that the preexisting value would point past the actual existing values! So just update it unconditionally in dive_list_update_dives(), which anything that changes the dive list is supposed to call in order to display the changes anyway. Also, just for safety, when removing a dive, put NULL in the last dive table location. Nobody should ever access past the end anyway (this is enforced by 'get_dive()') but there are places that access the dive list table directly, and the libdivecomputer download was one of those. No reason to leave stale dive pointers possibly around for uses like that.

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.

2013-01-22Add GPS icon to the location column for dive sites where we have GPS dataGravatar Dirk Hohndel
This replaces the really lame "italics text" from commit abe810ca1a29 ("Mark locations that have GPS location data attached") with a marginally less lame GPS icon.There's a reason why I am not making a living as graphics artist. But I think this is a huge step forward from what we had before... The satellite.svg file is very loosely based on a different icon that I found as public domain here http://www.clker.com/clipart-30400.html. From that I created the PNG and then that was converted into the GdkPixdata via gdk-pixbuf-csource; a rule for that was added to the Makefile but commented out as I don't know if this tool will always be available in the path. Having this icon included in the sources avoids locating yet another icon file. Better icons are certainly welcome! Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2013-01-20Mark locations that have GPS location data attachedGravatar Dirk Hohndel
This is rather lame - we simply turn the location text into italics for those dives where we have GPS location data. Underlining might be more natural, but Gtk plays games with the underline attribute if the mouse hovers over text. Ideally I would have prefered a little GPS logo next to the location text - but I couldn't figure out how to do that without writing my own cell renderer which seemed total overkill.

2013-01-13Correctly show the planned dive in the divelistGravatar Dirk Hohndel

2013-01-13During multi-dive deco calculations don't look at dives from other tripsGravatar Dirk Hohndel
Previously the code in init_decompression() would mindlessly walk back the dive_table until it found a gap of at least 48h and take all those dives into consideration when calculating tissue saturation. This goes horribly wrong if you load dives from two divers into the same data file.

2013-01-09Clean up duplicated depth interpolationGravatar Linus Torvalds
We have several places where we interpolate the depth based on two samples and the time between them. Some of them use floating point, some of them don't, some of them meant to do it but didn't. Just use a common helper function for it. I seriously doubt the floating point here really matters, since doing it in integers is not going to overflow unless we're interpolating between two samples that are hours apart at hundreds of meters of depth, but hey, it gives that rounding to the nearest millimeter. Which I'm sure matters. Anyway, we can probably just get rid of the rounding and the floating point math, but it won't really hurt either, so at least do it consistently. The interpolation could be for other things than just depth, but we probably don't have anything else we'd want to interpolate. But make the function naming generic just in case.

2013-01-08Rewrite of the deco codeGravatar Robert C. Helling
o) Instead of using gradient factors as means of comparison, I now use pressure (as in: maximal ambient pressure). o) tissue_tolerance_calc() now computes the maximal ambient pressure now respecting gradient factors. For this, it needs to know about the surface pressure (as refernce for GF_high), thus gets *dive as an argument. It is called from add_segment() which this also needs *dive as an additional argument. o) This implies deco_allowed_depth is now mainly a ambient-pressure to depth conversion with decorations to avoid negative depth (i.e. no deco obliation), implementation of quantization (!smooth => multiples of 3m) and explicit setting of last deco depth (e.g. 6m for O2 deco). o) gf_low_pressure_this_dive (slight change of name), the max depth in pressure units is updated in add_segment. I set the minimal value in buehlmann_config to the equivalent of 20m as otherwise good values of GF_low add a lot of deco to shallow dives which do not need deep stops in the first place. o) The bogus loop is gone as well as actual_gradient_limit() and gradient_factor_calculation() and large parts of deco_allowed_depth() although I did not delete the code but put it in comments. o) The meat is in the formula in lines 147-154 of deco.c. Here is the rationale: Without gradient factors, the M-value (i.e the maximal tissue pressure) at a given depth is given by ambient_pressure / buehlmann_b + a. According to "Clearing Up The Confusion About "Deep Stops" by Erik C. Baker (as found via google) the effect of the gradient factors is no replace this by a reduced affine relation (i.e. another line) such that at the surface the difference between M-value and ambient pressure is reduced by a factor GF_high and at the maximal depth by a factor GF_low. That is, we are looking for parameters alpha and beta such that alpha surface + beta = surface + gf_high * (surface/b + a - surface) and alpha max_p + beta = max_p + gf_low * (max_p/b + a - max_p) This can be solved for alpha and beta and then inverted to obtain the max ambient pressure given tissue loadings. The result is the above mentioned formula. Signed-off-by: Robert C. Helling <helling@atdotde.de> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

2013-01-06Display dive profile of the dive we plan, as we plan itGravatar Dirk Hohndel
As the user enters data into the entry fields, that data is validated and as soon as there is enough data we start constructing a dive profile, including the final ascent to the surface, including required deco stops, etc. This commit still has some serious issues. - when data is input that doesn't validate, we just print a warning to stdout - instead we need to change the backgroundcolor of the input field or something. - when we switch to the last dive in order to show the profile we don't actually search for the last dive - we just show the first one in the tree. This works for the default sort order but is of course wrong otherwise I'm sure there are many other bugs, but I want to push it out where it is right now for others to be able to take a look.

2013-01-04First stab at simplistic dive planningGravatar Dirk Hohndel
This comes with absolutely no gui - so the plan literally needs to be compiled into Subsurface. Not exactly a feature, but this allowed me to focus on the planning part instead of spending time on tedious UI work. A new menu "Planner" with entry "Test Planner" calls into the hard-coded function in planner.c. There a simple dive plan can be constructed with calls to plan_add_segment(&diveplan, duration, depth at the end, fO2, pO2) Calling plan(&diveplan) does the deco calculations and creates deco stops that keep us below the ceiling (with the GFlow/high values currently configured). The stop levels used are defined at the top of planner.c in the stoplevels array - there is no need to do the traditional multiples of 3m or anything like that. The dive including the ascents and deco stops all the way to the surface is completed and then added as simulated dive to the end of the divelist (I guess we could automatically select it later) and can be viewed. This is crude but shows the direction we can go with this. Envision a nice UI that allows you to simply enter the segments and pick the desired stops. What is missing is the ability to give the algorithm additional gases that it can use during the deco phase - right now it simply keeps using the last gas used in the diveplan. All that said, there are clear bugs here - and sadly they seem to be in the deco calculations, as with the example given the ceiling that is calculated makes no sense. When displayed in smooth mode it has very strange jumps up and down that I wouldn't expect. For example with GF 35/75 (the default) the deco ceiling when looking at the simulated dive jumps from 16m back up to 13m around 14:10 into the dive. That seems very odd.

2013-01-04Fix deco calculations to correctly use GF values and add CC supportGravatar Dirk Hohndel
The old implementation was broken in several ways. For one thing the GF values are percentages, so they should normally be 0 < GF < 1 (well, some crazy people like to go above that). With this most of the Bühlmann config constants were wrong. Furthermore, after we adjust the pressure tolerance based on the gradient factors, we need to convert this back into a depth (instead of passing back the unmodified depth - oops). Finally, this commit adds closed circuit support to the deco calculations. Major progress and much more useful at this stage. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

2013-01-03Improvements to select_prev_dive() and select_next_dive()Gravatar Lubomir I. Ivanov
There were some minor problems when moving the selection cursor around: 1) If the selection was larger than 1, it was possible for the selection to get "stuck" in the middle of the list. This patch approaches this by always calling gtk_tree_selection_unselect_all() before gtk_tree_selection_select_iter(), or simply always making sure we have one selected iterator when navigating with the keys. 2) When there was a single top level dive before the first trip it wasn't possible to navigate trough the child dives of said trip in both directions. The patch attempts to fix this by having the hunks/checks: if (idx < 0) { (idx is of a trip) performed regardless of other conditions. *** Note: testing was done by importing all test*.xml dives with auto-group on. [Dirk Hohndel: adjusted the patch to also fix on_key_press to only grab the key if no modifier key is pressed; otherwise this breaks shift-cursor-keys for selecting multiple dives.] Signed-off-by: Lubomir I.

2013-01-03Consider previous dives when calculating decoGravatar Dirk Hohndel
This also initializes the N2 tissue saturations to correct numbers (setting them to zero was clearly silly). With this commit we walk back in the dive_table until we find a surface intervall that's longer than 48h. Or a dive that comes after the last one we looked at; that would indicate that this is a divelist that contains dives from multiple divers or dives that for other reasons are not ordered. In a sane environment one would assume that the dives that need to be taken into account when doing deco calculations are organized as one trip in the XML file and so this logic should work. One major downside of the current implementation is that we recalculate everything whenever the plot_info is recreated - which happens quite frequently, for example when resizing the window or even when we go into loup mode. While this isn't all that compute intensive, this is an utter waste and we should at least cache the saturation inherited from previous dives (and clear that number when the selected dive changes). We don't want to cache all of it as the recreation of the plot_info may be triggered by the user changing equipment (and most importantly, gasmix) information. In that case the deco data for this dive does indeed have to be recreated. But without changing the current dive the saturation after the last surface intervall should stay the same.

2013-01-02Limit to 4 the number of cylinders shown in the data frameGravatar Salvador Cuñat
For dives with more than 4 cylinders, the frame got very crowded and we needed a magnifier to see the numbers. If we used more than four tanks, let's put the info in another frame, if not, print the OTUs, the maxcns and the weight sytem in the new frame. There is still room for two more short data. Changed naming of nitrox and trimix mixes. Changed cylinder description. There are issues with the size of some translations.

2013-01-02Fix mixed dive/trip tree model groupingGravatar Linus Torvalds
In commit 96db56f89c76 ("Allow overlapping (and disjoint) dive trips") I allowed dives to be part of arbitrary dive trips regardless of date, which meant that the divelist tree model code needed to find the right parent for a dive as it was inserted. That code stupidly assumed that the top level of the dive list tree containted *only* trips, which is not at all the case. It happens to be true if you group all your dives into divetrips (the common case for autogroup=1, which real users do tend to have), but now that Dirk made the autogrouping be a per-xml-file setting, it became much easier to trigger the "mixed trips and non-trip dives" case, and that showed the stupid bug with the test dives. So instead of just blindly iterating to the 'n'th entry, search for the actual entry that is the dive trip we want to associate a dive with.

2013-01-01First step towards grabbing keys and handling them ourselvesGravatar Dirk Hohndel
This commit steals the cursor up and down keys away from gtk so regardless where gtk thinks the focus may be, we can still use the keys to change between dives. In the current UI design where all editing happens in separate windows this works as expected, as we only grab the keys for the main window. If we manage to re-enable in-place editing then we need to make sure that this doesn't cause problems (as gtk uses up/down for the ability to change drop down selections in combo boxes or values in spin buttons. So we must make sure that we stop stealing these keys once we start editing something (in which case simply switching to the next/prev dive wouldn't be a good thing, anyway).
