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).

Read planner preferences when we use them Read and use the last_stop preference in the plan function. Read the plan notes preferences and set variables (plan_verbatim, plan_display_runtime, plan_display_duration, and plan_display_transitions) in the add_plan_to_notes function. Don't read the preferences and set variables otherwise. Both plan and add_plan_to_notes functions are called on data change. Previous behaviour was: - Set variables on declaration - Reset variables in plan function (even variables that only relate to planner notes output) - Changing a preference triggered set_xxx function which sets variable, then plan function, which sets variable again. Apart from being inefficient, the previous behaviour made it difficult to track down where and when variables were set.

VPM-B: Calculate ceiling in deepest portion of dive The Boyle's law compensation compares the ambient pressure to a baseline value, and adjusts the theory bubble radius accordingly. 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. This is particularly noticeable if the user enters stops during ascent. With this commit, we take the baseline ambient pressure for Boyle's law compensation as the deeper of the: (1) Ceiling prior to ascending during a user-entered portion of the dive, and (2) Ceiling at the start of the last user-entered waypoint. This makes the calculated profile more conservative for some deep to shallow multi-level dives. Signed-off-by: Rick Walsh <rickmwalsh@gmail.com> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

Use boyle_compensation in profile otherwise VPM-B planned profiles seem to violate the ceiling. This needs the first_stop_pressure to be available also in the profile, so I made it global in planner.c Important lesson: If you want to use deco_allowed_depth on a tissue_tolerance that comes from a VPM-B planned dive, you have to call boyles_law() before add_segment()!

With us now supporting dates earlier in 1900, this also makes "utc_mktime()" always add the "1900" to the year field. That way we avoid ever using the fairly ambiguous two-digit shorthand.

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.

void get_gas_at_time(struct dive *dive, struct divecomputer *dc, duration_t time, struct gasmix *gas)
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.

Calculate ceiling only when it is needed So far, add_segment() returned a tissue tolerance (i.e. ceiling) computed just in its return statement. This tissue_tolerance needed to be dragged around until it was needed or be dropped if not needed at all. 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>

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. Maybe at some point this was a feature. But it lead to a naughty bug which took me over an hour to resolve.

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.

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.

VPM-B: Calculate ceiling in deepest portion of dive The Boyle's law compensation compares the ambient pressure to a baseline value, and adjusts the theory bubble radius accordingly. 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. This is particularly noticeable if the user enters stops during ascent. With this commit, we take the baseline ambient pressure for Boyle's law compensation as the deeper of the: (1) Ceiling prior to ascending during a user-entered portion of the dive, and (2) Ceiling at the start of the last user-entered waypoint.

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.

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).

Simplify dive planning code This simplifies the dive planning code by: - allowing empty gas mixes (which means "pick previous gas") - avoiding unnecessary strdup/free calls (this requires us to handle "const char *" in the parsers, but that was already true from a code standpoint, just not a type one) - re-use the "plan()" function for a successful dive plan, rather than open-coding the dive plan segment handling.

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 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.

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.

Don't read the preferences and set variables otherwise. Both plan and add_plan_to_notes functions are called on data change. Previous behaviour was: - Set variables on declaration - Reset variables in plan function (even variables that only relate to planner notes output) - Changing a preference triggered set_xxx function which sets variable, then plan function, which sets variable again.

Fix deco_mode confusion 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). The former is set in the planner settings while the latter is set in the preferences. This patch clears up a confusion which of the two to use by introducing a helper function that selects the correct variable. Signed-off-by: Robert C. Helling <helling@atdotde.de>

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.

Planner notes - revise logic for gasmix output The logic for when to output a gasmix in the notes table is more complicated than it seems at first. - On a descent leg, the gas is the gas used for descent - At a stop (calculated or user defined), the gas is the gas used for that stop - But on an ascent leg (if displayed), the gas is the gas that is ABOUT TO BE USED - The gas should not be repeated if it's the same gas as used on the last row of the table - Ascent legs should only be displayed if the display transitions option is selected, OR if there is a gas change without a stop (the user can now set a minimum duration for a gaschange, but zero is still allowed). The existing code tries to track what gas is being used/switched to at each waypoint, and whether the gas should be printed or postponed to the next leg. It works sometimes but not always. This patch replaces the postponed gas logic with: - Is this an ascent leg? (determines whether the applicable gas is the preceding or following leg, and whether the leg should be displayed at all if the transitions option isn't selected) - Is it an ascent with a gaschange without a stop? - Has the gas actually changed from the last output? - Will the next leg be at the same level and same gas (in which case merge them)?

In diveplan differentiate between last printed depth and last depth In the decision if a dive segment should lead to a line in the diveplan, we need to differentiate between the lastdepth (the depth of the last dp to tell if we are currently stopping) and the last depth that we printed a line for (needed for gaschange lines). Without this patch, no stops without gas changes were listed anymore in the diveplan. Like the last patch for the diveplan: I hope this time I got this logic right. Signed-off-by: Robert C.

Print gas changes at the correct lines in diveplan This is a pain. We plan with segments but the plan shows waypoints. If after a constant depth segment the gaschange (or setpoint chenge for that matter) appears, the _next_ line should get the info about the new gas (i.e. change _after_ the constant depth segment).

The existing code tries to track what gas is being used/switched to at each waypoint, and whether the gas should be printed or postponed to the next leg. It works sometimes but not always. This patch replaces the postponed gas logic with: - Is this an ascent leg? (determines whether the applicable gas is the preceding or following leg, and whether the leg should be displayed at all if the transitions option isn't selected) - Is it an ascent with a gaschange without a stop? - Has the gas actually changed from the last output? - Will the next leg be at the same level and same gas (in which case merge them)?

The existing code tries to track what gas is being used/switched to at each waypoint, and whether the gas should be printed or postponed to the next leg. It works sometimes but not always. This patch replaces the postponed gas logic with: - Is this an ascent leg? (determines whether the applicable gas is the preceding or following leg, and whether the leg should be displayed at all if the transitions option isn't selected) - Is it an ascent with a gaschange without a stop? - Has the gas actually changed from the last output? - Will the next leg be at the same level and same gas (in which case merge them)?

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. The one issue that still bothers me is that we are juggling so many dive structures and then keep copying content around. It seems like we should be able to reduce that.

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>

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>

int ascent_velocity(int depth, int avg_depth, int bottom_time)
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.

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.

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.

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>

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.

// 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>

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.

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.

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.

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.

Commit 159c9eb2c1c19dfbf650f2b0cc28e0ef1f45c964, Compare ceiling to next stop rather than try to ascent for VPM-B, changed (VPM-B) to consider the current ceiling rather than an incremental ascent between one stop level and the next. However, the initial ascent generally steps through several stop levels, so first_stop_pressure was still not calculated as the ceiling prior to commencing the calculated ascent.

VPM-B: Calculate ceiling in deepest portion of dive The Boyle's law compensation compares the ambient pressure to a baseline value, and adjusts the theory bubble radius accordingly. 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. This is particularly noticeable if the user enters stops during ascent. With this commit, we take the baseline ambient pressure for Boyle's law compensation as the deeper of the: (1) Ceiling prior to ascending during a user-entered portion of the dive, and (2) Ceiling at the start of the last user-entered waypoint. This makes the calculated profile more conservative for some deep to shallow multi-level dives. Signed-off-by: Rick Walsh <rickmwalsh@gmail.com> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

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. Instead we would constantly try to switch to that gas and find we are already breathing it. A test case would be a dive with air and EAN50 to more than 66m. That would have never switched to EAN50.

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. Instead we would constantly try to switch to that gas and find we are already breathing it. A test case would be a dive with air and EAN50 to more than 66m. That would have never switched to EAN50.

Calculate ceiling only when it is needed So far, add_segment() returned a tissue tolerance (i.e. ceiling) computed just in its return statement. This tissue_tolerance needed to be dragged around until it was needed or be dropped if not needed at all. 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.

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.

VPM-B: add CVA to the deco planner. Added keeping bottom dive state and every deco's time, so we can run multiple deco simulations with different gradients until they converge to some optimal value. Some improvements on the deco time calculation may be needed. Signed-off-by: Jan Darowski <jan.darowski@gmail.com>

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>

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.
