2017-10-16In planner prefer best_first_ascend_cylinder for gas breaksGravatar Stefan Fuchs
Up to now the cylinder for gas breaks was hardcoded to first cylinder. With this change the best_first_ascend_cylinder is used if its O2 is <=32%. Signed-off-by: Stefan Fuchs <sfuchs@gmx.de>
2017-10-16Don't confuse cyl with same gasmix with best_first_ascend_gasGravatar Stefan Fuchs
When calculating the dive plan in the planner don't accidently use another gas with same gasmix instead of the gas stored as "best_first_ascend_gas". This is important if you have e.g. a bottom stage and back gas with same gas mix because then you always want to start your ascent with the gas you used in last entered dive planner point.

This option should have never been there. This is not how gradient factors are supposed to work. It would only trick users to use the wrong value.. Signed-off-by: Robert C. Helling <helling@atdotde.de>

2017-08-29Find deco stop time by binary search instead of iterationGravatar Robert C. Helling
This allows to go to much smaller granularity without severe performance penalty. It should also increase performance for long decompression times. Currently this leads to missing cached tissue factors, the caching has to be adopted to this. Also, for the time being this breaks the bottom gas breaks feature. Signed-off-by: Robert C. Helling <helling@atdotde.de>
2017-08-29Make plan take dive and decotimestep as argumentsGravatar Robert C. Helling
...rather than use a global variable and a macro. This should be a no-op in preparation to allow planning several versions of a dive. Signed-off-by: Robert C. Helling <helling@atdotde.de>
2017-07-20Unify sample pressure and o2pressure as pressure[2] arrayGravatar Linus Torvalds
We currently carry two pressures around for all the samples and plot info, but the second pressure is reserved for CCR dives as the O2 cylinder pressure. That's kind of annoying when we *could* use it for regular sidemount dives as the secondary pressure. So start prepping for that instead: don't make it "pressure" and "o2pressure", make it just be an array of two pressure values. NOTE! This is purely mindless prepwork. It literally just does a search-and-replace, keeping the exact same semantics, so "pressure[1]" is still just O2 pressure. But at some future date, we can now start using it for a second sensor value for sidemount instead.

2017-04-20Identify user provided notes in plain text in replanGravatar Robert C. Helling
This is another attept at the problem if identifying a potentially user supplied text in the dive notes upon replannig a dive. It gets rid of the user visable position markers (*!* and ***) and cirumvents problems with mark-up by first converting the old notes to plan text (assuming that user only enters plain text in the notes field as we do in other places as well). Then the automatically added part is identified by locating the disclaimer in the text (if the user edited/delted the disclaimer or changed langue in between it is her problem to manually delete the old plan). Everything from the disclaimer on is deleted and replaced by the new plan. If the disclaimer is not found, the new plan is appended to the old notes. This way we make sure no information gets automatically deleted. Signed-off-by: Robert C. Helling <helling@atdotde.de>
2017-04-20Show % after Büllmanns GFsGravatar Jan Mulder
2 strings in the planner output showed based on "Bühlmann ZHL-16B with GFLow = " gradient factors without % after the factor. While this is fine for an abbreviated form like GF 40/80, this looks strange for a verbose sentence like the 2 corrected ones. Signed-off-by: Jan Mulder <jlmulder@xs4all.nl>
2017-04-16Handle notes from plannerGravatar Stefan Fuchs
New strategy to identify old planner output in notes when replanning a dive: Text anchors ("*!*" and "***") added for planner output For backwards compatibility: If there is no anchor but an old table delete everything. Signed-off-by: Stefan Fuchs <sfuchs@gmx.de>

2017-03-28Handle notes in replanGravatar Robert C. Helling
Upon replanning a dive, we want to delete the old dive plan in the notes and replace it with the actual. This fixes a problem when we failed to detect the old plan due to the deco model name appearing in the disclaimer that was used as a marker for the notes. This patch also adds translation markers for the deco model name strings.. Fixes #285 Signed-off-by: Robert C. Helling <helling@atdotde.de>
2017-03-19Tests for minimum gasGravatar Stefan Fuchs
Add automatic tests in TestPlan for minimum gas: - Copy minimum gas result (pressure) to diveplan. - Add cylinder size and working pressure for bottom gas to every dive in TestPlan Hint: Unrealistic cylinder sizes (100l, 200l) have to be used for the very long and deep dives in TestPlan - Add minimum gas check for every dive - Add two additional test dives in TestPlan which produce sane minimum gas results with 24l tank Hint: Deco check for these new dives is commented out at the moment Signed-off-by: Stefan Fuchs <sfuchs@gmx.de>

Add minimum gas calculation to planner output. Add the two UI parameters prefs.sacfactor and prefs.problemsolvingtime. Connect UI signals and slots for recalculation of diveplan. Disable minimum gas calculation if there was already a warning before. If minimum gas result is larger then cylinder start pressure give warning message instead of result.

2017-03-09Fix potential double/float to int rounding errorsGravatar Jeremie Guichard
Not using lrint(f) when converting double/float to int creates rounding errors. This error was detected by TestParse::testParseDM4 failure on Windows. It was creating rounding inconsistencies on Linux too, see change in TestDiveDM4.xml. Enable -Wfloat-conversion for gcc version greater than 4.9.0 Signed-off-by: Jeremie Guichard <djebrest@gmail.com>
2017-03-08Change calls to rint into lrint avoiding conversion warningsGravatar Jeremie Guichard
Using gcc option "-Wfloat-conversion" is useful to catch potential conversion errors (where lrint should be used). rint returns double and still raises the same warning, this is why this change updates all rint calls to lrint. In few places, where input type is a float, corresponding lrinf is used. Signed-off-by: Jeremie Guichard <djebrest@gmail.com>

2017-02-11Set up gaslist only in the beginning of diveplanGravatar Robert C. Helling
In the beginning of the diveplan, divedatapoints of zero duration indicate available gases with the depth giving the suggested switch depth. Zero-duration datapoints in the middle of the dive do not have this meaning and should thus be ignored when composing the gaslist. The tests should have these gas defining segments in the beginning. This fixes a problem when replanning a dive that would change to random gases during deco. Signed-off-by: Robert C. Helling <helling@atdotde.de>

2017-01-06Fix deco_mode confusionGravatar Robert C. Helling
We have two prefernces determining the deco_mode (BUEHLMANN vs VPMB vs RECREATIONAL): One for the planner (deco_mode) and one for displaying dives (display_deco_mode).

2016-11-24Show effective gradient factors for VPMB-plansGravatar Robert C. Helling
For each stop, this computes an effective gradient factor that gives the same ceiling. Then, it does linear regression to find values for GFlow and GFhigh that give a similar deco profile. Note that this optimises the average gradient factor. The runtime however depends strongly at the gradient factor at the last depth. So we don't necessarily to get the runtime right.
