2015-08-25Make created dive site uuid deterministicGravatar Dirk Hohndel
Having random uuids seemed like a good idea, but there are several situations where they really cause problems. One is merging dive file imports from V2 logfiles. Another is testing such imports. Instead of making the uuid random we now hash the name and add the timestamp of the first dive associated with this dive site to the hash (first in this context is "first encountered" with no guarantee that it is the chronologically first). This way V2 imports create deterministic uuids but uuid conflicts are still extremely unlikely, even if the user has multiple dive sites with the same name.

2015-07-05Add simple test for the dive plannerGravatar Dirk Hohndel
This sets up a standard dive scenario (30 minutes at 260ft/79m, EAN36 and Oxygen as deco gases, last stop at 20ft/6m) and calls the planner to set up a dive plan given certain standard gases. Instead of trying to verify the complete plans it checks that we switch to the deco gases at the right depth and the complete duration of the dive matches our expectation. The test intentionally fails right now for imperial as we have the wrong switch depth for Oxygen. See how useful tests are? On the downside, the test does NOT produce the same plan as Subsurface when I try to create a consistent setup for both - and I have not been able to figure out why. There must be some other parameters that I'm not setting, but I haven't identified them, yet. It's very small differences, for example in the metric case the stops at 21m, 9m, and 6m are each one minute shorter in the test than it what Subsurface calculates.

2015-06-24Rewrite GPS fix matching code for imports from our webserviceGravatar Dirk Hohndel
The longer I stared at the existing code the less it made sense. So instead I rewrote it in a way that seems logical to me. And added a boatload of debugging output (which needs to be removed, of course). I tested this against more than a hundred dives and it seemed to always pick the right fix.

2015-06-17Make sure cylinder related data is filled when dives are readGravatar Dirk Hohndel
This is re-run every time we update the dive list model for the UI, but we should run it a first time right after loading the dives so that this data is correct even without the UI running - this way the data in headless standalone applications like the HTML exporter is correct as well.

2015-06-17Store the user's unit preferences in git storageGravatar Dirk Hohndel
Save and load a usually unused copy of the preferences with the units that were active the last time the dive list was saved to git storage (this isn't used in XML files); storing the unit preferences in the data file is usually pointless (that's a setting of the software, not a property of the data), but it's a great hint of what the user might expect to see when creating a backend service that visualizes the dive list without Subsurface running - so this is basically a functionality for the core library that Subsurface itself doesn't use but that another consumer of the library (like an HTML exporter) will need.

2015-04-24Allow images to be added via the webGravatar Robert C. Helling
This adds a new divelist context menu entry which asks for a URL. The file is retrieved and if it is an image it is added to the cache and the url is associated to dives as with local files. NB this currently only works with URLs pointing directly to images. But it should not be too hard to add the possibility to add a direction via an html file and its image tags.

2015-04-23When deleting a cylinder, adapt gas changesGravatar Dirk Hohndel
When we delete a cylinder the gas changes in that dive may have to be adjusted. We didn't do this at all in the past. With this commit we should be doing this right for a single dive that is being edited. This does NOT handle multiple dives being edited at the same time (or more specifically - if you have multiple dives selected and delete a cylinder, the dives that had the same set of cylinders (other than the displayed dive) will get that particular cylinder deleted, but won't have their gas change events (and sensor data in the samples) adapted. Possibly we should simply prohibit deleting cylinders when more than one dive are selected. See #834 Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

2015-03-10Import Datatrak/WLog filesGravatar Salvador Cuñat
Sequentially parses a file, expected to be a Datatrak/WLog divelog, and converts the dive info into Subsurface's dive structure. As my first DC, back in 90s, was an Aladin Air X, the obvious choice of log software was DTrak (Win version). After using it for some time we moved to WLog (shareware software more user friendly than Dtrak, printing capable, and still better, it runs under wine, which, as linux user, was definitive for me). Then, some years later, my last Aladin died and I moved to an OSTC, forcing me to look for a software that support this DC. I found JDivelog which was capable of import Dtrak logs and used it for some time until discovered Subsurface existence and devoted to it. The fact was that importing Dtrak dives in JDivelog and then re-importing them in Subsurface caused a significant data loss (mainly in the profile events and alarms) and weird location of some other info in the dive notes (mostly tag items in the original Dtrak software). This situation can't actually be solved with tools like divelogs.de which causes similar if no greater data loss. Although this won't be a core feature for Subsurface, I expect it can be useful for some other divers as has been for me. Comments and issues: Datatrak/Wlog files include a lot of diving data which are not directly supported in Subsurface, in these cases we choose mostly to use "tags". The lack of some important info in Datatrak archives (e.g. tank's initial pressure) forces us to do some arbitrary assumptions (e.g. initial pressure = 200 bar). There might be archives coming directly from old DOS days, as first versions of Datatrak run on that OS; they were coded CP437 or CP850, while dive logs coming from Win versions seems to be coded CP1252. Finally, Wlog seems to use a mixed confusing style. Program directly converts some of the old encoded chars to iso8859 but is expected there be some issues with non alphabetic chars, e.g. "ª". There are two text fields: "Other activities" and "Dive notes", both limited to 256 char size. We have merged them in Subsurface's "Dive Notes" although the first one could be "tagged", but we're unsure that the user had filled it in a tag friendly way. WLog adds some information to the dive and lets the user to write more than 256 chars notes. This is achieved, while keeping compatibility with DTrak divelogs, by adding a complementary file named equally as the .log file and with .add extension where all this info is stored. We have, still, not worked with this complementary files. This work is based on the paper referenced in butracker #194 which has some errors (e.g. beginning of log and beginning of dive are changed) and a lot of bytes of unknown meaning. Example.log shows, at least, one more byte than those referred in the paper for the O2 Aladin computer, this could be a byte referred to the use of SCR but the lack of an OC dive with O2 computer makes impossible for us to compare. The only way we have figured out to distinguish a priori between SCR and non SCR dives with O2 computers is that the dives are tagged with a "rebreather" tag. Obviously this is not a very trusty way of doing things. In SCR dives, the O2% in mix means, probably, the maximum O2% in the circuit, not the O2% of the EAN mix in the tanks, which would be unknown in this case. The list of DCs related in bug #194 paper seems incomplete, we have added one or two from WLog and discarded those which are known to exist but whose model is unknown, grouping them under the imaginative name of "unknown". The list can easily be increased in the future if we ever know the models identifiers. BTW, in Example.log, 0x00 identifier is used for some DC dives and from my own divelogs is inferred that 0x00 is used for manually entered dives, this could easily be an error in Example.log coming from a preproduction DC model. Example.log which is shipped in datatrak package is included in dives directory for testing pourposes.

2015-02-27Add hashes to imagesGravatar Robert C. Helling
Upon successfull reading an image file, this computes a SHA1 hash of the image and saves it with the picture tag in the log file. When a file is not successfully loaded (for example because the log was created on a different computer) we look up the hash in a dictionary that maps hashes to local file names. That dictionary (actually two for both directions), is loaded on startup and saved upon destruction of the main window. Signed-off-by: Robert C.

2015-02-07Deal with setpoints in samples when switching a dive from CCR to OCGravatar Dirk Hohndel
For some dive computers (at least the Shearwater Predator, I haven't checked if there are others), libdivecomputer used to return setpoint values in each sample even if the dive computer was in OC mode. Those setpoint values are redundant and confuse our algorithm that tries to detect if a dive is OC or CCR. So when manually switching from CCR to OC we make sure that there are no setpoint values in the samples. This is a destructive change - if the user switches to OC by mistake and accepts that change, even when switching back to CCR the setpoint changes during the dive are lost. I rewrote the code dealing with the events as it was rather confused. Looping over the events that way didn't make any sense since get_next_event() is guaranteed to give you the first (if any) event of the requested name.
