0e196310f9 cleanup: split out divecomputer functions from dive.c
Since dive.c is so huge, split out divecomputer-related functions
into divecomputer.[c|h], sample.[c|h] and extradata.[c|h].

This does not give huge compile time improvements, since
struct dive contains a struct divecomputer and therefore
dive.h has to include divecomputer.h. However, it make things
distinctly more clear.

4aa571d5a0 cleanup: remove get_times() functions
The function
1) was misnamed: it determined the time of the first selcted dive.
2) had only one caller.
3) would crash if there was no selected dive.

Let's just fold the functionality into the caller. It's a one-liner
anyway.

8e330f297e cleanup: fix over-eager Coverity warnings
Technically get_dive() could return a nullptr. The existing code made sure the
argument passed to get_dive() was one that always would result in a valid dive
pointer being returned. The new code is only slightly less efficient but allows
a static code analysis to easily see that we don't derefence NULL pointers here.

On some level this change is unnecessary. But it's also not wrong.

74d84a959a divecomputer: add device to provided table instead of global table
In the specuial case of suunto, where we may add a device directly
instead of via dive->dc, add the device to the provided table.
The caller will then pass on the new device to the undo system.
This makes downloading finally really undoable (at least I
hope so). So far, the dives and dive sites were removed, but any
new device remained.

However, when setting the device-id via serial, we now have
to check both, the global and the downloaded list of devices.

2bcb3d88a0 divecomputer: add device_table pointer to device_data_t
In one weird case (suunto), the code in libdivecomputer.c
generates a device node directly instead of going the usual
way (setting the data in the dc-structure of the imported
dive). It is unclear to me whether that has to be that way,
as it depends on the chronological order of callbacks to
event_cb() and dive_cb().

Therefore add a device_table pointer to device_data_t
so that the downloader can add the device to this table. This
only adds the pointer, but does not yet use it in the
downloading code.

b9b51ffd4e core: add a small helper-struct that keeps track of xml-parameters
The XML-parameter code is a mess. Ownership is unclear. Allocation
and freeing of strings is in different functions. Sometimes
only every second string is free()d, because keys are not copied.
But this is done inconsistently. The caller has to know how
many parameters the callee may add.

Instead, let's add a small helper-struct that uses C++ memory
management, but exports a C-API. The array for the XML-library
is generated on the fly.

a7bbb6c1cc filter: remove filter_preset_table_t
We used a typedef "filter_preset_table_t" for the filter preset table,
because it is a "std::vector<filter_preset>". However, that is in
contrast to all the other global tables (dives, trips, sites) that we
have.

Therefore, turn this into a standard struct, which simply inherits
from "std::vector<filter_preset>". Note that while inheriting from
std::vector<> is generally not recommended, it is not a problem
here, because we don't modify it in any shape or form.

However, that meant that any pointer could be passed as

fd8bd9d5c7 cleanup: use std::string in struct device
struct device is a core data structure and therefore shouldn't use QString.
QString stores as UTF-16 (which is a very questionable choice in itself).
However, the real problem is that this puts us in lifetime-management
hell when interfacing with C code: The UTF-16 has to be converted to
UTF-8, but when returning such a string, this puts burden on the caller
who has to free it. In fact, instead of looping over devices from C-code
we had a callback that sent down temporary C-strings with qPrintable.

In contrast, std::string is guaranteed to store its data as
contiguous null-terminated and C-compatible strings. Therefore,
replace the QString by std::string. Keep the QString just in
one place that formats a hexadecimal number to avoid any
potential change.

The disadvantage of using std::string is that it will crash
when constructed with a NULL argument, consistent with C-style
functions such as strcmp, etc. Arguably, NULL is different
from the empty string even though we treat both as the same.

2e5913d2ba core: fix detection of duplicate device names
Recently (c9b8584bd2) the sort criteria of the device-table
was changed from  (model/id) to (id/model). However, that
messed with the detection of duplicate device names: there,
the code searched for the first element greater or equal
to (model / 0).

With the reversal of the sort criteria, this would now
always give the first element.

Therefore, do a simple non-binary search, which is much
more robust. The binary search was a silly and pointless
premature optimization anyway - don't do such things
if not necessary!

Since only one place in the code search for existence
for a model-name, fold the corresponding function into
that place.

Moreover, change the code to do a case-insensitive compare.
This is consistent with the dc_match_serial() code in
core/libdivecomputer.c, where matching models is
case-insensitive!

c9b8584bd2 core: sort device-table by id/model instead of model/id
The device table is accessed by core via a callback using
call_for_each_dc(). This sorts the table by device-id. It
is unclear whether this is needed - since currently all it
does is make sure that the devices have a fixed order in XML
and git log files.

In any case, this means that the table had to be copied and
sorted in call_for_each_dc(). Since the frontend now does
its own sorting, we can just keep the core table sorted
as it needs it. This in turn will ultimately make it possible
to replace the callback by a simple loop.

6729428b6a core: improve merging of cylinders pressures
When merging cylinders pressures derived from samples were taken
as maximum of the start and minimum of the end pressure, which
makes sense, since we believe that this is the same cylinder.

However, for manually entered pressures, this was not done.

Moreover, when one dive had manual pressures and the other only
pressure from samples, the manual pressure was taken. However,
that could have been the wrong one, for example if the end
pressure was manually set for the cylinder of the first part of
the dive, but not the last.

Therefore, improve merging of manuall set pressures in two ways:
1) use maximum/minimum for start/end pressure
2) if the pressure of one cylinder was manually set, but not for
   the other, complete with the sample pressure (if that exists).

Fixes #2884.

Instead of just 'BT' or 'device name' (which is wrong in cases where we don't

5bc6f5d36c cleanup: make device code more consistent with core
We keep track of device, i.e. distinct dive computers with id in the core.
The corresponding code stuck out like a sore thumb. Firstly, because it
is C++. But more importantly, because it used inconsistent nameing conventions.

Notably it defined a "DiveComputerNode" when this is something very different
from "struct dive_computer", the latter being the dive-computer related
data of a single dive.

Since the whole thing is defined in "device.h" and the function to create
such an entry is called "create_device_node", call the structure "device".
Use snake_case for consistency with the other core structures.

Moreover, call the collection of devices "device_table" in analogy
with "dive_table", etc.

Overall, this should make the core code more consistent style-wise.

d8f35711ff membuffer: be defensive about bad C library vsnprintf implementations
Dirk reports that some Windows users have had odd corruption in the
commit messages in the cloud storage.  They make no sense at all unless
there is some very weird Windows library bug.

The prime suspect is 'vsnprintf()' returning a negative error when the
target buffer is too small (rather than the proper "this is how much
space it would need").  That is a very traditional C library bug that I
thougth had been fixed everywhere, but there doesn't really seem to be a
lot of other likely causes.

So let's make our membuffer code be defensive against bad libraries that

4608beaee4 Android BLE discovery: use discovery agent
Android can't scan for classic BT devices, so when BT support was first
added, we simply didn't use the discovery agent at all and relied on the
list of paired BT devices provided by Android.

This still worked fine for a lot of BLE devices that allowed 'bonding'
with the Android device - similar to pairing. But some BLE devices (like
the Shearwater Peregrine) don't support bonding and so our Android code
didn't see them at all.

With this commit we start a BLE only scan on Android to add to the list

3bfd448b59 filter: implement saving of filter presets to git repositories
On the mailing list it was decided that users might want to
move their filter presets across computers via the cloud.
Notably, in the future one might access statistics on mobile and
these might by controlled by filter presets.

The git save routines use the same string formatting as the
XML save routines. The string formatting is found in
core/filterconstraint.cpp. Thus, duplication of code and
inconsistencies should be minimized.

Each filter preset is saved into a file in the "02-Filterpresets"
folder in the root of the git repository.

Each file consists of one "name" line, zero or one "fulltext" line
and zero or more "constraint" lines.

The modes, types and the actual payload is controlled via attributes.
Thus, a preset file might look like this:

name "test"
fulltext mode="substring" query="clown"
constraint type="location" stringmode="starstwith" data="mafia"
constraint type="sac" rangemode="range" negate data="5000,10000"

41cf83583d filter: load filter presets from XML files
This is a bit painful: since we don't want to modify the filter
presets when the user imports (as opposed to opens) a log,
we have to provide a table where the parser stores the presets.
Calling the parser is getting quite unwieldy, since many tables
are passed. We probably should introduce a structure representing
a full log-book at one point, which collects all the things that
are saved to the log.

Apart from that, this is simply the counterpart to saving to XML.
The interpretation of the string data is performed by core
functions, not the parser itself to avoid code duplication with
the git parser.

448bc5600b filter: implement saving of presets to XML file
Users might want to move their presets with there log-file. Therefore,
save the presets to the log. The alternative would be to save them
to the preferences. However, on the mailinglist it was decided that
moving the presets to a mobile device is a wanted feature.

The XML saving code has a rather reasonable interface, therefore
this turned out to be pretty easy to implement.

The filter presets are saved into a
<filterpresets>
 ...
</filterpresets>
block

Each individual preset is saved into a
 <filterpreset name='...'>
    ...
 </filterpreset>
Block with a unique name attribute.

Each preset contains zero or one fulltext and zero or more constraint entries.
The type and mode(s) are controlled by attributes, the "payload" is saved in
the block. Note that all the formatting is done by functions in core/filterconstraint.c
and not the parser itself.

A preset in the XML file might look like this:

 <filterpreset name='test1'>
  <fulltext mode='startswith'>Train</fulltext>
  <constraint type='planned'>0,0</constraint>
  <constraint type='sac' range_mode='range' negate='1'>5000,10000</constraint>

634152ae43 filter: add filter constraint object to the core
Adds a filter constraint object to the core, which represents one
constraint the user can filter dives with. The plan is to write these
constraints to the XML and git logs. Therefore, this code is written
in C-style except when it comes to handling strings and dates, which
is just too painful in plain C.

There is one pointer to QStringList in the class, though when compiled
with C, this is simply transformed into a pointer to void. Granted,
that smells of an ugly hack. However it's more pragmatic than
self-flaggelation with C string and list handling.

A filter constraint is supposed to be a very general thing, which can
filter for strings, multiple-choice lists, numerical ranges and date
ranges.

Range constraints have a range mode: less-or-equal, greater-or-equal
or in-range. Text constraints have a string mode: startswith, substring
or exact.

All the data are accessed via setter and getter functions for
at least basic levels of isolation, despite being written with
a C-interface in mind.

a7ca27d071 Prefer "GPS1" for divecomputer download dive site resolution
I think we only have one dive computer that supports GPS data right now:
the Garmin Descent Mk1.  It reports the dive coordinates as "GPS1" and
"GPS2" for the entry point and exit point respectively.

Often GPS1 is missing, because the dive computer may not have gotten a
GPS lock before the diver jumped into the water, so when that happens
we'll use GPS2 for the dive site location.  But when GPS1 exists, we
should prefer that.

And that's what we already did in logic in dc_get_gps_location(), but
for the initial dive site created at download time, we just picked any
divecomputer reported string that started with "GPS".  And since GPS2 is
reported after GPS1 by the Garmin Descent, it would end up overwriting
the entry point that we _should_ have preferred.

Add the same kind of "explicitly prefer GPS1" logic to the initial dive
download case as we already had elsewhere.

Silly typo with a missing 'i' in 'uuid' that happened when I wrote this

Fix it now, since I'll extend the uuid matching to the actual

ff14ca4dd5 translations: use the right Qt translations (part 2)
It turns out that contrary to what the documentation states, a few languages
are still only using the 'qt' translation. But those exist for all languages,
so we need to first search for the 'qtbase' translations, and only if that
fails do we try to load the 'qt' translations.

And even that will fail for languages in which Qt simply isn't localized (like
Dutch).

To make the code more readable, the check for 'US English' was moved earlier as
there is no point to look for a Qt translation for that (simply doesn't exist).

1ed8cb373f translations: use the right Qt translations and try harder to find them
We were still using the 'qt' translations instead of 'qtbase' as we should have
been using since forever - it's a little unclear from reading the documentation
when in the Qt5 life cycle this happened, but definitely several years ago.
These are the strings used in situations where Qt already provides us with text
(e.g., the entries in the 'Subsurface' menu on Mac, or the button labels in
many dialogs).

Additionally we didn't try hard enough to find those translations in cases
where they are bundled with the app; so basically all scenarios except for
Linux distro specific packages or 'build from source' on macOS or Linux were
not going to work, even after addressing the qt->qtbase conversion.

But of course the developers pretty much all fall into those last two
categories. Still, I cannot believe we never fixed this in all those years...

To make it more obvious if we still aren't finding the Qt translations this
commit also makes that warning be shown in all cases, not just when running in
verbose mode.

a01ab81713 cleanup: fold core/divecomputer.cpp into core/device.c
core/device.h was declaring a number of functions that were related
to divecomputers (dcs): creating a fake dc for manually entered dives
and registering / accessing dc nicknames. On could argue whether
these should be lumped together, but it is what it is.

However, part of that was implemented in C++/Qt code in a separate
core/divecomputer.cpp file. Some function therein where only
accessible to C++ and declared in core/divecomputer.h.

All in all, a big mess. Let's simply combine the files and
conditionally compile the C++-only functions depending on
the __cplusplus define.

Yes, that means turning device.c into device.cpp. A brave soul

6ea0cc62b8 desktop: refine auto-fill of weights
In a previous commit, auto-filling of weight based on type was
changed to be only performed if the user hadn't already set a
weight, by testing for weight=0.

However, when the user edited the type and tabbed back and forth,
that counted as an edit and therefore the weight would not
change anymore.

To refine this, introduce an "auto_filled" flag to the weightsystem,
which is set if the weight is automatically filled and cleared if
the weight is edited. Update the weight if it was zero *or* auto-filled.

The flag is not saved to disk, but that should be acceptable. If the
user saves and reloads, we can assume that they meant the weight
to be set to the default value.

This adds a common macro to convert salinity (which is
given as a density in terms of g per 10l) to a specific

The weired factor of 10 (from the unusual unit of salinity)
is included in the macro. It is there for historical reasons,
as it goes back to 05b55542c8 from 2012 where it was introduced
in code for downloading from Uemis dive computers.

d404aa767f [Bug #2934] Geo Lookup - support for remote dive sites
Some remote dive sites have no populated places (towns, cities)
nearby. For such sites, we now fall back to looking up
unpopulated place names, such as the reef or island name.

Also some code refactorisation:
the actual network access is now encapsulated in its own
function removing some duplicated code handling in the
reverseGeoLookup function and making it more readable.

Furthermore, reverseGeoLookup() was completely refactored as
most of its functionality was due to legacy requirements; the
current code-base only calls this function from a single
location and only with an empty taxonomy_data object. This
makes the function more focussed and much simpler and more
readable.

Finally, a resource leak in reverseGeocde introduced in
4f3b26f9b6 was fixed.

The dive_data table is then queried for each dive to get samples.

The seac action computer is the only current supported computer

parser will toggle between two cylinders whenever it detects a
change in the active O2 mix.

Dive start time is stored in UTC with a timezone offset.

c888a1727e DataTrak import: Add support for WLog extensions.
WLog is a Win32 based ancient shareware program whose target was:
1) fully support divelogs coming from DataTrak (DOS or Win)
2) fill some meaningful data which wasn't supported by Uwatec software
3) have a more user-friendly GUI than Datatrak had
The problem achieving goals 1) and 2) at the same time was solved by
adding a complementary file with .add extension and - mandatory - same
base name than .log file (including directory tree).

This .add file has a fixed structure composed of a 12 bytes header,
including file type check and Nº of dives following; then a fixed 850
bytes size for each dive in the log file. Data fields size and position
are fixed inside these blocks and heavily zero padded, so they are easy
to parse.

A serious restriction imposed to the WLog user was *Do not edit the logs
with other software than Wlog*; this was due the order of dives in .log
file being the same than the order of dives in .add file. Thought you
could show a WLog divelog in Datatrak, editing it resulted in mixing all
extended data for dives following the edited one.
Thus, we have to trust files are correct and is to the user ensure this
is so. If extended data are mangled, they are mangled in WLog too and we
are not trying to fix the mess, just importing.

On the technical side, we try to be smart about tank names as neither
DataTrak nor WLog record them. So we just take the first tank in users
list matching the volume recorded in WLog.
For weights we add a translatable "unknown" string as an empty string
results in weight not being shown in subsurface-mobile (which could be a
reportable issue, BTW).

Moreover, it does bound checking and is more flexible with respect to

This patch unifies the accesses by consistently switching to get_cylinder().
The affected code is in C++ and accesses the cylinder as reference or

getFormattedCylinder() is a helper function to format a list

would instead be written as "unkown".

The reason was the old statically sized cylinder array,
where it wasn't clear if a cylinder was actually in use.

This became obsolete when switching to a variable size
cylinder array. Firstly, all cylinders in the array were added
by the user. Secondly, we now also support dives without
cylinders, i.e. the first cylinder is not any different from
the rest.

Thus, remove the logic and format any cylinder without
description as being of type "unknown".

77a11400a1 Fix event merging when merging dives
The merge_events() function was subtly and not-so-subtly broken in a
couple of ways:

 - in commit 8c2383b49 ("Undo: don't modify source-dives on merge"), we
   stopped walking the event list after we merged the first event from a
   dive when the other dive computer had run out of events.

   In particular, this meant that when merging consecutive dives, the
   second dive only had the first event copied over to the merged dive.

   This happened because the original code just moved the whole old list
   over when there was nothing left from the other dive, so the old code
   didn't need to iterate over the event list. The new code didn't
   realize that the pointer movement used to copy the whole rest of the
   list, and also stopped iterating.

   In all fairness, the new code did get the time offset right, which
   the old code didn't. So this was always buggy.

 - similarly, the "avoid redundant gas changes" case was not handled for
   the "we ran out of events for the other dive computer" case.

This fixes both issues.

9d2449c5c3 mobile/location-service: fix timezone issue in GPS timestamps

definition "right around now". So using gettimezoneoffset() with the
current time seems "good enough".

8b478a969d git-storage: add global flag to indicate successful cloud sync
This may seem like a bit heavy handed as it adds more global state, but given
the number of ways in which attempts to sync with the cloud can fail it seems
much more reliable to claim success in the spots where we actually know that we
have successfully synced with the remote server. Transporting that information
back through the various call chains turned out to be very disruptive and ugly,
so I went with global state instead.

Whenever we access cloud storage (or any git repo), we always first check if it
actually is a git repo by calling is_git_repository() - so this is the perfect
spot to initialize the variable to false.

And there are only two spots where we either clone the remote repo
(create_local_repo()) or update the remote with the (potentially merged) local
changes (check_remote_status()). So those are the two places where we set the
variable to true.

e91c252093 BLE: add list of known good/bad BLE GATT services
We've tried to do this "automagic" service discovery, and it mostly
works, but then occasionally it doesn't.

Making things worse, I think different platforms end up enumerating
services differently, so our "pick the first service that looks like it
might be a serial service" ends up working on some platforms, but not
necessarily on others.  Because "first" might be different.

So start a list of known good/bad services - and fall back to the old
logic when you can't decide reliably.

This fills in juat a few cases that I can easily check myself, and the
"details" field for them may be incomplete.  For example, I know Nordic
Semiconductor has their vendor-specific UUIDs, and they can be found in
different devices, so calling them "Nordic UART" and "Nordic Flash"
services makes sense.

But the "Scubapro i770R" service? It might indeed be specific to the
Scubapro i770R.  Or it might be a general service UUID that Pelagic
uses.  Or it might be the service UUID of a particular chip, and found
in dive computers from other designs too (and not necessarily in all
i770R's either).

So this is a preliminary first stab at this, and I'm sure we'll extend
the list and possibly improve on the explanations.

658089d763 core/bt: match DC descriptor in lower case
This fixes a rather subtle bug.

In btdiscovery.cpp we are detecting dive computers based on their BT name and
are setting up product+vendor as the key for that lookup. QMap always uses case
sensitive comparisons and a tiny inconsistency snuck into our code.
libdivecomputer names for the Aqualung dive computers i200C / i300C / i550C end
in an upper case C (as matches the official branding), but in btdiscovery.cpp
we have those names with lower case c. And therefore didn't recognize these
dive computers.

Obviously this is easy to fix by fixing those three strings, but I decided that
it was silly to set ourselves up for similar oversights in the future. So
instead I switched the matching of the descriptor to simply be allways all
lower case.

fb6210a99a cleanup: invert control-flow when resetting the core structures
To reset the core data structures, the mobile and desktop UIs
were calling into the dive-list models, which then reset the
core data structures, themselves and the unrelated
locationinformation model. The UI code then reset various other
things, such as the TankInformation model or the map. . This was
unsatisfying from a control-flow perspective, as the models should
display the core data, not act on it. Moreover, this meant lots
of intricate intermodule-dependencies.

Thus, straighten up the control flow: give the C core the
possibility to send a "all data reset" event. And do that
in those functions that reset the core data structures.
Let each module react to this event by itself. This removes
inter-module dependencies. For example, the MainWindow now
doesn't have to reset the TankInfoModel or the MapWidget.

Then, to reset the core data structures, let the UI code
simply directly call the respective core functions.

Indeed, in a very cache friendly test (16 entries, tight loop) calling the

  - with cache: 604 ms
  - without cache: 266 ms
