2014-11-22Check error code of get_cylider_idx_by_use()Gravatar Robert C. Helling
If not cylinder with type DILUENT or OXYGEN is defined, this function returns -1 which should not be used as an index to an array. This patch adds code to check for this return value and exit gracefully. On line I marked with a comment. Someone more knowledgeable of that part of code than me should double check that return is here what we want. [Dirk Hohndel: fixed small oversight...] Signed-off-by: Robert C.

2014-11-18Fix crash when opening Poseidon_MkVILog.xmlGravatar Dirk Hohndel
In commit d5d7fdc9af98 ("For CCR dives, show plot for diluent and O2 cylinder pressures") we end up dereferencing current before it is first initialized. Bad. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

Also fixes a bug in the diluent pressure interpolation Signed-off-by: Robert C. Helling <helling@atdotde.de> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2014-11-17For CCR dives, the diluent cylinder is the current cylinderGravatar Robert C. Helling
Change the meaning that _the_ cylinder (as we treat it in OC dives) is the diluent cylinder (rather than the O2 cylinder). This eliminates special cases. Now, for CCR, we have to handle the O2 cylinder in addition (rather than the diluent in addition). Signed-off-by: Robert C. Helling <helling@atdotde.de> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2014-11-17More CCR code cleanupGravatar Dirk Hohndel
Random constants are bad. Let's use the indices that we already calculated (and true and false if we mean boolean values). Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2014-11-16Some gas handling improvementsGravatar Robert C. Helling
Add a time linear gas interpolation strategy. Some minor changes. Signed-off-by: Robert C. Helling <helling@atdotde.de> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2014-09-11CCR patch: adapt code for diluent cylinder pressures (3)Gravatar willem ferguson
This patch implements the cylinder pressure calculations for diluent gas in CCR dive computers. This is the third patch for achieving this. The following were performed: 1) Add two lines to try_to_fill_sample() in parse-xml so that diluent cylinder pressures are stored from XML dive log file into structures of sample. 2) Add one line to populate_plot_entries() in profile.c so that the diluent cylinder pressures are copied from structures of sample to structures of plot_info. 3) add three constant #defines in profile.h 4) change populate_pressure_information() in gaspressures.c in order to take into account pressure calculations for the diluent cylinder, calling subordinate functions in the appropriate way. 5) change create_plot_info_new() in profile.c in order to initiate the pressure calculations for the diluent cylinder. 6) Implement two debugging functions (one in profile.c, another in gaspressures.c). These debugging functions are activated by means of #defines. Two function calls dealing with oxygen pressure are currently commented out. They will be activated in the following patch that attends to CCR oxygen partial pressure calculation.

2014-08-28CCR patch: Adapt pressure interpolation for CCR (2)Gravatar willem ferguson
This is the second pathch in this series of four, allowing the calculation of cylinder pressures for CCR equipment. Change function fill_missing_tank_pressures in order to enable working with the diuent gas, comprising a complete set of pressures kept separate from all other tank pressures. Flag diluent_flag indicates calculations for the diluent cylinder.

2014-08-27CCR Patch: Adapt pressure interpolation for CCRGravatar willem ferguson
This patch adapts pressure interpolation (function pr_interpolate_data) in order to process CCR diluent gas as well. A flag diluent_flag is added to the variables for calling this function indicating whether the gas being worked with is diluent gas or not. This is necessitated by the fact that the diluent gas storage is separate from that of the other gases. The data used for interpolation are selected from the appropriate array, depending on nthe value of diluent_flag. In function fill_missing_tank_pressures, diluent_flag is set to 0 in order for the code to work with the current CCR adaptations. The above constitutes no. 1 of a four-part set of patches that allows pressure calculations for CCR gases. There will be CCR functionality only after the whole set of patches is complete.

2014-08-25Code cleanup: gaspressures.cGravatar Willem Ferguson
This patch does some cleaning up of code after the previous CCR patch that extracted the contents of gaspressures.c form profile.c 1) Inapplicable #defines were removed 2) static function types were reinstated where practically possible. 3) comments at the start of the file were expanded a bit.

2014-08-25CCR code: Split profile.c into two files, with gas caluclations separate.Gravatar Willem Ferguson
This patch implements a separation of the code for gas pressure calculations from the rest of the code in profile.c. The latter file is now split into: profile.c and gaspressures.c. The details of the transferred functions is given at the top of gaspressures.c. The following chnages were made: 1) dive.h: The function types of calculate_depth_to_mbar and depth_to_mbar were made non-static in order to make them available within gaspressures.c. 2) profile.c: Prototypes for the functions in gaspressures.c were inserted at the top of profile. Ten functions were transferred from profile.c to gaspressures.c 3) gaspressures.c as well as a short header, gaspressures.h were created. For the gas pressure calculations for CCR dives, gaspressures.c forms the immediate basis for further code development.
