2018-05-14Core: introduce new subsurface-string headerGravatar Dirk Hohndel
First small step to shrinking dive.h. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2018-01-11Introduce helper function empty_string()Gravatar Berthold Stoeger
There are ca. 50 constructs of the kind same_string(s, "") to test for empty or null strings. Replace them by the new helper function empty_string(). Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-01-05core: free() in a safe way, reverse geolookup unstabilityGravatar Jan Mulder
A simple one line change that solves (for me) numerous hard crashes when adding geo tags by reverse lookup from the dive site edit screen. This is one of those crashes that is might not be reproducible on any platform, or even between different builds on one platform. This said, I found that the free() on line 99 of divesitehelpers.cpp tried to free pointers to random data, ie. not pointing to valid taxonomy category strings. And those pointers where simply caused by freeing the string earlier, and leaving the pointer around. So, this change is nothing more than setting the just freed pointer to NULL, to allow free() to be called later safely. Signed-off-by: Jan Mulder <jlmulder@xs4all.nl>
2017-12-31divesite.c: use union in create_divesite_uuid()Gravatar Lubomir I. Ivanov
The return produces a warning about "strict-aliasing rules". Use a union to fit the hash and the uint32_t into the same block of memory, which obeys the GCC strict-aliasing rules. Signed-off-by: Lubomir I. Ivanov <neolit123@gmail.com>
2017-12-19git storage: invalidate cache on merge dive siteGravatar Jan Mulder
In hindsight a very simple bug to fix, but it requires some knowledge on the inner workings of our git storage. The changes on merge of dive sites were simply not saved (completely) because the git storage code has a cache that we need to invalidate selectively (ie. for the dive we just gave a new dive site uuid) to get things finally embedded in the overall commit. The main reason this bug went unnoticed for more than 2 years is that most people use the XML/SSRF format (where this problem is non exsistent), and dive site merging is probably not a very much used feature either. Fixes: #939 Signed-off-by: Jan Mulder <jlmulder@xs4all.nl>
2017-10-05divesite.c: use NULL instead of 0 for char* buffersGravatar Lubomir I. Ivanov
Makes it clearer that these are buffers and not integers like `ds->uuid`. Signed-off-by: Lubomir I. Ivanov <neolit123@gmail.com>
2017-10-05divesite.c: prevent double free()Gravatar Lubomir I. Ivanov

2017-10-04Don't add separate country field, use taxonomyGravatar Dirk Hohndel
The more I looked at the code that added the country to the dive site, the more it seemed redundant given what we have with the taxonomy. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2017-10-04Add taxonomy copy helper functionGravatar Dirk Hohndel
We don't want to just be able to copy all of a dive site. Sometimes we might want to be able to copy just the taxonomy. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2017-10-02[Divesite] Add country on divesiteGravatar Tomaz Canabrava
Add more information for the divesite, a country can be used to help sorting. Signed-off-by: Tomaz Canabrava <tcanabrava@kde.org> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2017-04-29Add SPDX header to remaining core filesGravatar Dirk Hohndel
Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2017-03-09Fix potential double/float to int rounding errorsGravatar Jeremie Guichard
Not using lrint(f) when converting double/float to int creates rounding errors. This error was detected by TestParse::testParseDM4 failure on Windows. It was creating rounding inconsistencies on Linux too, see change in TestDiveDM4.xml. Enable -Wfloat-conversion for gcc version greater than 4.9.0 Signed-off-by: Jeremie Guichard <djebrest@gmail.com>
2017-02-19Fix dive site string mergingGravatar Linus Torvalds
If the second dive site doesn't have a particular string, but the first one does, we did the wrong thing and created a result string like (first dive site string) or ((null)) which is not useful. We should just use the first dive site string as-is. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2017-02-19Properly handle dive sites loaded from XMLGravatar Linus Torvalds
We used to always create a new dive site structure when loading dive site data from XML. That is completely bogus, because it can (and does) create duplicate dive sites with the same UUID. Which makes the whole UUID pointless. So instead, look up the existing dive site associated with the UUID loaded from the XML, and try to merge the data properly if we already had dive site information for that UUID.

2016-04-04Move subsurface-core to core and qt-mobile to mobile-widgetsGravatar Dirk Hohndel
Having subsurface-core as a directory name really messes with autocomplete and is obviously redundant. Simmilarly, qt-mobile caused an autocomplete conflict and also was inconsistent with the desktop-widget name for the directory containing the "other" UI. And while cleaning up the resulting change in the path name for include files, I decided to clean up those even more to make them consistent overall. This could have been handled in more commits, but since this requires a make clean before the build, it seemed more sensible to do it all in one. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
