First stab at simplistic dive planning 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.

Planner: change timestep to 2 seconds Change the timestep used to calculate tissue pressures and ascents from 3 seconds to 2 seconds. But whats wrong with using 3 seconds? Deco stops are at 3 m (10') intervals, and our ascent rate is usually 9 m/min (30'/min), or at least multiples of 3 m/min (10'/min). Hence time to ascend from one stop to the next stop is 20s (or any factor of 60). Using 3s increments, we round our ascent interval up to 21 s, which leads to messy durations and runtimes. But what about me? I like SI units and whole decimals. Don't worry, 2s timesteps fit nicely when using 10 m/min ascent rate (18 s between stops).

Planner deco stops are at 10ft increments when measured in feet When using feet as depth unit, deco stop levels should be at 10 ft rather than 3 m increments. For shallow stops, rounding means the difference is not apparent. However, with stops deeper than 30 feet, using 3 m increments leads stops at 39ft, 49ft, ..., 98ft, etc. Apart from making plans look messy, the old behaviour makes it harder to benchmark the planner against published profiles in imperial units. This revised patch uses the help macro M_OR_FT(6, 20) to set the last stop at the correct depth. Signed-off-by: Rick Walsh <rickmwalsh@gmail.com> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

Add GFlow/GFhigh settings in dive planner The planner interactively responds to changes to the GFlow and GFhigh in the dialog and calculates an appropriate profile. If there is a previous dive within the 48 hours prior to this dive then its saturation is correctly taken into account if the gradient factors are changed - so if they are aggressively lowered it is possible to start the dive with already an existing ceiling (simply increase the surface interval to 'fix' that). Once the plan is accepted the GF values are reset to the current preferences. This can cause the ceiling in the plot to change and the deco stops to no longer match the ceiling - but that's a logical consequence of the ability to change a temporary copy of GFlow/GFhigh during the planning process and not the actual preferences (which would be counter intuitive, I think).

Add support to planner to use additional gases during the ascent This change ended up being quite a bit bigger than expected as it uncovered a number of bugs in the existing code. The planner now handles gas changes correctly by creating (and later parsing) events in the simulated divecomputer. At the end of the dive specified in the input form the algorithm starts with the deepest interesting depth: either the first stop below our ceiling or the deepest depth at which we can change gases. It then traverses all the stop and all the gas change depth and at each stage ensures that we are allowed to ascend further before going on. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

get_gas_at_time needs to always give us a valid gas Before this function was changed it was really supposed to just change a gas that was passed in in case there was an event that changed the mix - but with the new name the caller will assume that they get a valid gasmix. And promptly we had one caller that didn't initialize gas to be based on the first cylinder before calling get_gas_at_time(). Instead of adding yet one more spot that knows about the oddity of the old API I simply changed get_gas_at_time() to do what it name appears to imply and fixed the other callers not to bother to initialize the gasmix.

Have divedatapoint store cylinder id instead of gasmix Determining the correct cylinder index from a known gas mix can be complicated, but it is trivial to look up the gasmix from the cylinder_t structure. It makes sense to remember which cylinder is being used. This simplifies handling changing a cylinder's gas mix, either directly by the user, or indirectly in the planner. It also permits tracking of multiple cylinders of the same mix, e.g. independent twins / sidemount. Signed-off-by: Rick Walsh <rickmwalsh@gmail.com> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

Use proper types This is step one of many to use gasmix instead of int o2/he. Right now some of these changes look ridiculous because after changing a few lines we immediately go back to o2 = get_o2(gas). The reason is that I wanted to convert a hand full of functions at a time. So in this commit I only change validate_gas(), get_gas_from_events() and get_gasidx() to use a struct gasmix instead of int o2, int he. This state builds and survived some mild testing.

Make gas change events always have a cylinder index In commit df4e26c8757a ("Start sanitizing gaschange event information") back about a year and a half ago, I started sanitizing the gas switch event data, allowing gas switches to be associated with a particular cylinder index rather than just the gas mix that is switched to. But that initial step only _allowed_ a gas switch event to be associated with a particular cylinder, the primary model was still to just specify the mix. This finally takes the next step, and *always* associates a gas switch event with a particular cylinder. Instead of then looking up the cylinder by trying to match gas mixes at runtime, subsurface now looks it up when loading the dive initially as part of the dive fixup code. The switch event still has an a separate gas mix associated with it, but this patch also starts preparing for entirely relying on the gas mix in the cylinder itself, by starting to pass in not just the event but also the dive pointer to the routines that look up gas mix details.

This tissue_tolerance needed to be dragged around until it was needed or be dropped if not needed at all.

void interpolate_transition(struct dive *dive, duration_t t0, duration_t t1, depth_t d0, depth_t d1, const struct gasmix *gasmix, o2pressure_t po2)
Improvement for various bits of the planner Rewrite of the actual planner logic. Now ascend to the next potential stop depth. There the state is cached and we try to ascend to the next stop depth. If we hit the ceiling while doing that we go back to the cached state and wait there for a minute. Then we try again. Then loop. Converted all depth related variables from unsigned int to int. During planning, in a time step the current depth can temporarily be negative and comparisons of a negative int with an unsigned it have not the result I expected ( (int) -2 < (unsigned int) 3 turns out to be false). And we don’t really need the 32nd bit that unsigned buys us for depths. Deco stops are now shown in the same table as manually entered stops in boldface (I removed the second table to save screen estate). The gas shown in the table is still misleading as it means the gas used on the segment leading up to that event. The update of the profile only works partially upon changes in the list of available gases. Treatment of various gases is basically there but needs some more love. The ascent velocity is now provided by a function that takes the current depth as argument. Currently it always returns 10m/min but that will later be variable (and hopefully user configurable). The profile is not redrawn while deco is computed (avoiding an infinite recursion). The table got a new column for the duration of a segment while the old “duration” column was renamed “Runtime” to reflect what it actually shows. Currently, only the run time but not the duration are editable. All deco gases are used from the depth where their pO2 is 1.4bar. This should become more flexible. Calculation of the pressure drop in cylinders without configured volumes is suppressed. This solves a problem with the planner crashing when saving a dive where not all cylinders had been manually given a volume. [Short rant break: Treating 0/0 as air bites back at so many places. E.g. Cylinder data is initialized with memsetting the whole structures to 0. Then later suddenly this totally unconfigured cylinder is being treated as it would contain air.

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.

As for VPM-B, this ceiling computation is a bit expensive, this patch calls the computation function tissue_tolerance_calc() when the value is actually needed and not before. This changes the signature of some functions. Signed-off-by: Robert C. Helling <helling@atdotde.de> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

First stab at simplistic dive planning 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.

get_gas_at_time needs to always give us a valid gas Before this function was changed it was really supposed to just change a gas that was passed in in case there was an event that changed the mix - but with the new name the caller will assume that they get a valid gasmix. And promptly we had one caller that didn't initialize gas to be based on the first cylinder before calling get_gas_at_time(). Instead of adding yet one more spot that knows about the oddity of the old API I simply changed get_gas_at_time() to do what it name appears to imply and fixed the other callers not to bother to initialize the gasmix.

Currently we use the ceiling at the last user-entered waypoint (the start of the decompression phase) as the baseline value. However, in a deep to shallow multi-level dive, decompression can start earlier, and taking a shallower ceiling leads to a more aggressive ascent.

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. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

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.

First stab at simplistic dive planning 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.

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.

For now this state is lost when saving the dive file as we don't add this flag in the sample to our saved files. So if we don't find any samples marked as manually added we add ALL of the samples as way points on the diveplan and the user has to manually remove the ones that were calculated.

Make planner work again for CCR dives The latest CCR patches had rendered the planner not usable for CCR dives. This patch corrects this (and reenables the CCR set point column for segments). The problem was that a new member setpoint of struct divepoint had been introduced, but there was already po2 which had the same meaning.

Allow special entries in diveplan for available gases An entry with no time is considered special and not considered when constructing the profile. This should allow us to add support for two different ways of adding information about available gas: changedepth 0 gasmix 0 0 gasmix @ po2 The first syntax basically says "during the ascent, switch to this gas at this depth. The second one says "switch to this gas once the pO2 allows for it" Neither of these are implemented, yet, but this commit is necessary in order for the rest of the code to ignore entries with a time field of 0.

First stab at simplistic dive planning 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.

Make dive planner more useful for closed circuit diving 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).

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.

Make planner work again for CCR dives The latest CCR patches had rendered the planner not usable for CCR dives. This patch corrects this (and reenables the CCR set point column for segments).

Make planner work again This partially reverts changes in commit 1b655d5c806b ("Correctly track gases when manually adding and then editing dives") as it turns out this did NOT help us correctly track gases (which is ironic, given the title of that commit). I didn't actually want to revert that commit as infrastructure has changed since then and this made the patches look even more incomprehensible. So we are back to tracking the "gas on which we arrive at this spot" in each dive plan node as this makes the rest of our planning so much easier - I had forgotten about the reasons why we did things this way when I made the above mentioned commit. Instead we now make sure that our available tanks are added the correct way, that such entries are ignored when planning and when drawing the editable profile, and that at the end it all gets assembled correctly.

Add support to planner to use additional gases during the ascent This change ended up being quite a bit bigger than expected as it uncovered a number of bugs in the existing code. The planner now handles gas changes correctly by creating (and later parsing) events in the simulated divecomputer. At the end of the dive specified in the input form the algorithm starts with the deepest interesting depth: either the first stop below our ceiling or the deepest depth at which we can change gases. It then traverses all the stop and all the gas change depth and at each stage ensures that we are allowed to ascend further before going on. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

Deco stops are now shown in the same table as manually entered stops in boldface (I removed the second table to save screen estate). The gas shown in the table is still misleading as it means the gas used on the segment leading up to that event. The update of the profile only works partially upon changes in the list of available gases. Treatment of various gases is basically there but needs some more love. The ascent velocity is now provided by a function that takes the current depth as argument. Currently it always returns 10m/min but that will later be variable (and hopefully user configurable). The profile is not redrawn while deco is computed (avoiding an infinite recursion). The table got a new column for the duration of a segment while the old “duration” column was renamed “Runtime” to reflect what it actually shows. Currently, only the run time but not the duration are editable. All deco gases are used from the depth where their pO2 is 1.4bar. This should become more flexible. Calculation of the pressure drop in cylinders without configured volumes is suppressed. This solves a problem with the planner crashing when saving a dive where not all cylinders had been manually given a volume. [Short rant break: Treating 0/0 as air bites back at so many places. E.g. Cylinder data is initialized with memsetting the whole structures to 0. Then later suddenly this totally unconfigured cylinder is being treated as it would contain air. Maybe at some point this was a feature. But it lead to a naughty bug which took me over an hour to resolve. We should seriously reconsider this choice and better move to 209/0 being air if changing this everywhere is not too much trouble] Signed-off-by: Robert C.

First stab at simplistic dive planning 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.

First stab at simplistic dive planning 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.

Make planner work again This partially reverts changes in commit 1b655d5c806b ("Correctly track gases when manually adding and then editing dives") as it turns out this did NOT help us correctly track gases (which is ironic, given the title of that commit). I didn't actually want to revert that commit as infrastructure has changed since then and this made the patches look even more incomprehensible. So we are back to tracking the "gas on which we arrive at this spot" in each dive plan node as this makes the rest of our planning so much easier - I had forgotten about the reasons why we did things this way when I made the above mentioned commit. Instead we now make sure that our available tanks are added the correct way, that such entries are ignored when planning and when drawing the editable profile, and that at the end it all gets assembled correctly.

Add support to planner to use additional gases during the ascent This change ended up being quite a bit bigger than expected as it uncovered a number of bugs in the existing code. The planner now handles gas changes correctly by creating (and later parsing) events in the simulated divecomputer. At the end of the dive specified in the input form the algorithm starts with the deepest interesting depth: either the first stop below our ceiling or the deepest depth at which we can change gases. It then traverses all the stop and all the gas change depth and at each stage ensures that we are allowed to ascend further before going on. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

Improvement for various bits of the planner Rewrite of the actual planner logic. Now ascend to the next potential stop depth. There the state is cached and we try to ascend to the next stop depth. If we hit the ceiling while doing that we go back to the cached state and wait there for a minute. Then we try again. Then loop. Converted all depth related variables from unsigned int to int. During planning, in a time step the current depth can temporarily be negative and comparisons of a negative int with an unsigned it have not the result I expected ( (int) -2 < (unsigned int) 3 turns out to be false). And we don’t really need the 32nd bit that unsigned buys us for depths. Deco stops are now shown in the same table as manually entered stops in boldface (I removed the second table to save screen estate). The gas shown in the table is still misleading as it means the gas used on the segment leading up to that event. The update of the profile only works partially upon changes in the list of available gases. Treatment of various gases is basically there but needs some more love. The ascent velocity is now provided by a function that takes the current depth as argument. Currently it always returns 10m/min but that will later be variable (and hopefully user configurable). The profile is not redrawn while deco is computed (avoiding an infinite recursion). The table got a new column for the duration of a segment while the old “duration” column was renamed “Runtime” to reflect what it actually shows. Currently, only the run time but not the duration are editable. All deco gases are used from the depth where their pO2 is 1.4bar. This should become more flexible. Calculation of the pressure drop in cylinders without configured volumes is suppressed. This solves a problem with the planner crashing when saving a dive where not all cylinders had been manually given a volume. [Short rant break: Treating 0/0 as air bites back at so many places. E.g. Cylinder data is initialized with memsetting the whole structures to 0. Then later suddenly this totally unconfigured cylinder is being treated as it would contain air.

// Do we want deco stop array in metres or feet?
Planner deco stops are at 10ft increments when measured in feet When using feet as depth unit, deco stop levels should be at 10 ft rather than 3 m increments. For shallow stops, rounding means the difference is not apparent. However, with stops deeper than 30 feet, using 3 m increments leads stops at 39ft, 49ft, ..., 98ft, etc. Apart from making plans look messy, the old behaviour makes it harder to benchmark the planner against published profiles in imperial units. This revised patch uses the help macro M_OR_FT(6, 20) to set the last stop at the correct depth. Signed-off-by: Rick Walsh <rickmwalsh@gmail.com> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

Planner deco stops are at 10ft increments when measured in feet When using feet as depth unit, deco stop levels should be at 10 ft rather than 3 m increments. For shallow stops, rounding means the difference is not apparent. However, with stops deeper than 30 feet, using 3 m increments leads stops at 39ft, 49ft, ..., 98ft, etc. Apart from making plans look messy, the old behaviour makes it harder to benchmark the planner against published profiles in imperial units.

During planning, in a time step the current depth can temporarily be negative and comparisons of a negative int with an unsigned it have not the result I expected ( (int) -2 < (unsigned int) 3 turns out to be false). And we don’t really need the 32nd bit that unsigned buys us for depths. Deco stops are now shown in the same table as manually entered stops in boldface (I removed the second table to save screen estate). The gas shown in the table is still misleading as it means the gas used on the segment leading up to that event. The update of the profile only works partially upon changes in the list of available gases. Treatment of various gases is basically there but needs some more love. The ascent velocity is now provided by a function that takes the current depth as argument. Currently it always returns 10m/min but that will later be variable (and hopefully user configurable). The profile is not redrawn while deco is computed (avoiding an infinite recursion). The table got a new column for the duration of a segment while the old “duration” column was renamed “Runtime” to reflect what it actually shows. Currently, only the run time but not the duration are editable. All deco gases are used from the depth where their pO2 is 1.4bar. This should become more flexible. Calculation of the pressure drop in cylinders without configured volumes is suppressed.

First stab at simplistic dive planning 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.

Don't do a negative time step in recreational mode when beyond NDL In recreational mode, we keep adding time at the last depth until an ascent does violate the ceiling. Then we roll back the last added time step and record the ascent. The test for the ceiling violated was before adding the time so if it alreay failed the first time we tried to unroll a time step that was never added which resulted in a small kink in the pressure graph.

Improvement for various bits of the planner Rewrite of the actual planner logic. Now ascend to the next potential stop depth. There the state is cached and we try to ascend to the next stop depth. If we hit the ceiling while doing that we go back to the cached state and wait there for a minute. Then we try again. Then loop. Converted all depth related variables from unsigned int to int. During planning, in a time step the current depth can temporarily be negative and comparisons of a negative int with an unsigned it have not the result I expected ( (int) -2 < (unsigned int) 3 turns out to be false). And we don’t really need the 32nd bit that unsigned buys us for depths. Deco stops are now shown in the same table as manually entered stops in boldface (I removed the second table to save screen estate). The gas shown in the table is still misleading as it means the gas used on the segment leading up to that event. The update of the profile only works partially upon changes in the list of available gases. Treatment of various gases is basically there but needs some more love. The ascent velocity is now provided by a function that takes the current depth as argument. Currently it always returns 10m/min but that will later be variable (and hopefully user configurable). The profile is not redrawn while deco is computed (avoiding an infinite recursion). The table got a new column for the duration of a segment while the old “duration” column was renamed “Runtime” to reflect what it actually shows. Currently, only the run time but not the duration are editable. All deco gases are used from the depth where their pO2 is 1.4bar. This should become more flexible. Calculation of the pressure drop in cylinders without configured volumes is suppressed. This solves a problem with the planner crashing when saving a dive where not all cylinders had been manually given a volume. [Short rant break: Treating 0/0 as air bites back at so many places. E.g. Cylinder data is initialized with memsetting the whole structures to 0. Then later suddenly this totally unconfigured cylinder is being treated as it would contain air. Maybe at some point this was a feature. But it lead to a naughty bug which took me over an hour to resolve. We should seriously reconsider this choice and better move to 209/0 being air if changing this everywhere is not too much trouble] Signed-off-by: Robert C.

stopping = true;
Improvement for various bits of the planner Rewrite of the actual planner logic. Now ascend to the next potential stop depth. There the state is cached and we try to ascend to the next stop depth. If we hit the ceiling while doing that we go back to the cached state and wait there for a minute. Then we try again. Then loop. Converted all depth related variables from unsigned int to int. During planning, in a time step the current depth can temporarily be negative and comparisons of a negative int with an unsigned it have not the result I expected ( (int) -2 < (unsigned int) 3 turns out to be false). And we don’t really need the 32nd bit that unsigned buys us for depths. Deco stops are now shown in the same table as manually entered stops in boldface (I removed the second table to save screen estate). The gas shown in the table is still misleading as it means the gas used on the segment leading up to that event. The update of the profile only works partially upon changes in the list of available gases. Treatment of various gases is basically there but needs some more love. The ascent velocity is now provided by a function that takes the current depth as argument. Currently it always returns 10m/min but that will later be variable (and hopefully user configurable). The profile is not redrawn while deco is computed (avoiding an infinite recursion). The table got a new column for the duration of a segment while the old “duration” column was renamed “Runtime” to reflect what it actually shows. Currently, only the run time but not the duration are editable. All deco gases are used from the depth where their pO2 is 1.4bar. This should become more flexible. Calculation of the pressure drop in cylinders without configured volumes is suppressed. This solves a problem with the planner crashing when saving a dive where not all cylinders had been manually given a volume. [Short rant break: Treating 0/0 as air bites back at so many places. E.g. Cylinder data is initialized with memsetting the whole structures to 0. Then later suddenly this totally unconfigured cylinder is being treated as it would contain air. Maybe at some point this was a feature. But it lead to a naughty bug which took me over an hour to resolve. We should seriously reconsider this choice and better move to 209/0 being air if changing this everywhere is not too much trouble] Signed-off-by: Robert C.

Decrease gaschange index even if we are already breathing the new mix This fixes a bug where we would not do any gas changes at all if at the end of bottom time we were deeper than the MOD of the bottom mix.

Improvement for various bits of the planner Rewrite of the actual planner logic. Now ascend to the next potential stop depth. There the state is cached and we try to ascend to the next stop depth. If we hit the ceiling while doing that we go back to the cached state and wait there for a minute. Then we try again. Then loop. Converted all depth related variables from unsigned int to int. During planning, in a time step the current depth can temporarily be negative and comparisons of a negative int with an unsigned it have not the result I expected ( (int) -2 < (unsigned int) 3 turns out to be false). And we don’t really need the 32nd bit that unsigned buys us for depths. Deco stops are now shown in the same table as manually entered stops in boldface (I removed the second table to save screen estate). The gas shown in the table is still misleading as it means the gas used on the segment leading up to that event. The update of the profile only works partially upon changes in the list of available gases. Treatment of various gases is basically there but needs some more love. The ascent velocity is now provided by a function that takes the current depth as argument. Currently it always returns 10m/min but that will later be variable (and hopefully user configurable). The profile is not redrawn while deco is computed (avoiding an infinite recursion). The table got a new column for the duration of a segment while the old “duration” column was renamed “Runtime” to reflect what it actually shows. Currently, only the run time but not the duration are editable. All deco gases are used from the depth where their pO2 is 1.4bar. This should become more flexible. Calculation of the pressure drop in cylinders without configured volumes is suppressed. This solves a problem with the planner crashing when saving a dive where not all cylinders had been manually given a volume. [Short rant break: Treating 0/0 as air bites back at so many places. E.g. Cylinder data is initialized with memsetting the whole structures to 0. Then later suddenly this totally unconfigured cylinder is being treated as it would contain air. Maybe at some point this was a feature. But it lead to a naughty bug which took me over an hour to resolve. We should seriously reconsider this choice and better move to 209/0 being air if changing this everywhere is not too much trouble] Signed-off-by: Robert C.

VPMB: calculate deco_time assuming final ascent always takes the same time If we consider the actual time to ascend from the final stop when calculating deco_time, then slowing the final ascent can lead to the final stop being extended, which is completely nonsensical. For consistency with the original VPMB implementation, we can't ignore the final ascent time completely, but if we assume it is always the same (take default ascent rate of 9m/min) then slower the final ascent won't lead to a longer final stop.

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. Signed-off-by: Robert C.

Add support to planner to use additional gases during the ascent This change ended up being quite a bit bigger than expected as it uncovered a number of bugs in the existing code. The planner now handles gas changes correctly by creating (and later parsing) events in the simulated divecomputer. At the end of the dive specified in the input form the algorithm starts with the deepest interesting depth: either the first stop below our ceiling or the deepest depth at which we can change gases. It then traverses all the stop and all the gas change depth and at each stage ensures that we are allowed to ascend further before going on. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

First stab at simplistic dive planning 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.
