2018-05-13Dive pictures: replace picture struct by QStringGravatar Berthold Stoeger
In imagedownloader.cpp the only thing we need from the picture struct is the filename. Therefore, use QStrings instead of the picture struct. This simplifies memory management. Remove the clone_picture() function, which is not needed anymore. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-05-13Dive pictures: save thumbnails to individual filesGravatar Berthold Stoeger
The old code loaded all thumbnails into memory at once. This does not scale to logs with thousands of pictures. Therefore, save the pictures to individual files and only load the currently needed pictures. Currently, this will make changing switching between dives slower, because the thumbnails are loaded from disk. In the future, it is planned to do this in a background thread without blocking the user interface. A notable difference to the old code: Thumbnails are now indexed by the image-hash (i.e. the content of the raw image) and not by the filename of the image. Thus, different paths to the same image should only be saved once. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-04-11Cleanup: unconstify results of two functionsGravatar Berthold Stoeger
get_dive_date_c_string() and get_current_date() return copied strings. Make this explicit by returning non-const pointers. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-04-09Cleanup: Move *_loc formatting functions into new format.cpp fileGravatar Berthold Stoeger
qthelper.cpp is already quite voluminous. Move the recently introduced localized versions of (v)snprintf() and put_format() into their own translation unit. Moreover, adopt C-style semantics for asprintf_loc(). This function will be used to remove fixed-size buffers in core/plannernotes.c. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-04-09Change taglist_get_tagstring to support 'unlimited' tag list sizeGravatar Jeremie Guichard
Previous taglist_get_tagstring signature/implementation did not allow handling of cases where inputted buffer could not contain all tags. New implementation allocates buffer based on pre-computed size allowing to insert all tags in the returned string. Added get_taglist_string in qthelper to handle conversion to QString Added TestTagList with tests for taglist_get_tagstring Signed-off-by: Jeremie Guichard <djebrest@gmail.com>
2018-03-14Cleanup: introduce copy_qstring() functionGravatar Berthold Stoeger
strdup(qPrintable(s)) and copy_string(qPrintable(s)) were such common occurrences that they seem worthy of a short helper-function. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-03-05Cleanup: Remove hash field from picture-structureGravatar Berthold Stoeger
The hash field in the picture-structure was in principle non-operational. It was set on loading, but never actually changed. The authoritative hash comes from the filename->hash map. Therefore, make this explicit by removing the hash field from the picture structure. Instead of filling the picture structure on loading, add the hash directly to the filename->hash map. This is done in the register_hash() function, which does not overwrite old entries. I.e. the local hash has priority over the save-file. This policy might be refined in the future.

2018-03-05Cleanup: pass QString and QByteArray const-refs to qthelper functionsGravatar Berthold Stoeger
Passing of QStrings and QByteArrays was inconsistent in qthelper.cpp. Unify to passing const-references. Passing by value is no big deal, since QString and QByteArray do copy-on-write "optimization". Nevertheless, let's keep it as consistent and effective as possible. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-03-05Cleanup: Fold add_hash() call into learnHash() functionGravatar Berthold Stoeger
learnHash() was always called in conjunction with add_hash(). The pattern was that a local filename and a hash were connected in the hash-to-filename and the filename-to-hash maps. Then, the original picture-filename or url were registered in the filename-to-hash map. This commit changes learnHash() to take three parameters (original-filename, local-filename and hash) and do all of the above. The new code is simpler because no dummy picture struct has to be generated in DiveListView::loadImageFromURL(). The tests were extended to check for all hash<->filename associations. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-03-05Cleanup: Don't store hash in picture struct in learnHash()Gravatar Berthold Stoeger
learnHash() is called either on a local picture structure [DiveListView::loadImageFromURL()] or on a cloned picture structure [ImageDownloader::saveImage()]. In neither case the picture structure is passed to the frontend. Therefore, storing the new hash in the picture struct is not necessary. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2018-03-05Localization: Make Qt's locale-aware formatting accessible from CGravatar Berthold Stoeger
This commit introduces functions: - QString asprintf_loc(const char *cformat, ...); - int snprintf_loc(char *dst, size_t size, const char *cformat, ...); - put_format_loc(struct membuffer *, const char *fmt, ...); and their va_arg equivalents, which use Qt's QString::arg() formatting options to render the strings. The snprintf_loc() function takes care not to truncate multi-byte UTF-8 encodings. Thus, on overflow, the resulting string might be shorter than size-1.

2018-02-26Cleanup: Unify qthelper.h and qthelperfromc.hGravatar Berthold Stoeger
Since all qt-helpers are defined in qthelper.cpp, there seems to be no reason to have two include files. By unifying the two files, duplication and inconsistencies are removed. The C++-only part is simply compiled away with #ifdefs. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>

2017-11-25Localize global planner stateGravatar Robert C. Helling
For UI responsiveness, we need to be able to run the planner in the background. This needs the planner state to be localized (and we need to pass a pointer around). In order to not let too many lines overrun (and to save typing in the future) I have renamed instances of struct deco_state to ds. Yes this should have gone to a separate commit but I accidentally commit --amend'ed it. Computing of planner variations is temporarily disabled. Unlock the planner when returning early So we don't deadlock in add dive and recreational mode (which use the planner without actually planning). Signed-off-by: Robert C. Helling <helling@atdotde.de>

2017-05-07Refactor Seabear importGravatar Miika Turkia
Moving the GUI independent Seabear import functionality to Subsurface core. This will allow Robert to call it directly from download from DC. Tested with H3 against released and daily versions of Subsurface. The result differs somewhat, but it is actually fixing 2 bugs: - Temperature was mis-interpreted previously - Sample interval for a dive with 1 second interval was parsed incorrectly Signed-off-by: Miika Turkia <miika.turkia@gmail.com>

2017-01-06Fix deco_mode confusionGravatar Robert C. Helling
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>

2016-07-09Have divedatapoint store cylinder id instead of gasmixGravatar Rick Walsh
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>
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>
