2013-06-24Enable downloads from the UEMIS ZurichGravatar Dirk Hohndel
This behaves somewhat differently from the Gtk version - still needs more investigation. But at least now it's hooked in. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2013-05-03Remove the majority of the Gtk related codeGravatar Dirk Hohndel
- rip all Gtk code from qt-gui.cpp - don't compile Gtk specific files - don't link against Gtk libraries - don't compile modules we don't use at all (yet) - use #if USE_GTK_UI on the remaining files to disable Gtk related parts - disable the non-functional Cochran support while I'm at it Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2013-04-07Fix some of the gcc-4.8 warningsGravatar Dirk Hohndel
Most of the warnings are IMHO false positives: e.g.: an enum variable is initialized in a switch statement that has a case for each possible enum value - yet gcc 4.8 warns that it could be used uninitialized; or: two variables are initialized together in the code - second one of them is previously initialized to -1 at declaration time, both are initialized in an if (second one == -1) clause - so they are guaranteed to both be initialized... I did not "fix" those as the code is actually correct. But there are three spots where it catches things that could indeed go wrong (with odd input data in one of them). This commit also adds a check to only call g_type_init() for older versions of glib as in newer ones it is deprecated. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2013-04-06Separate Gtk related code from core logic: divelistGravatar Dirk Hohndel
This is simplistic & brute force: any function that touches Gtk related data structures is moved to divelist-gtk.c, everything else stays in divelist.c. Header files have been adjusted so that this still compiles and appears to work. More thought is needed to truly abstract this out, but this seems to be a good point to commit this change.

2013-03-03Try to capture some more potential buffer overflows caused by localizationGravatar Dirk Hohndel
A couple of these could clearly cause a crash just like the one fixed by commit 00865f5a1e1a ("equipment.c: Fix potential buffer overflow in size_data_funct()"). One would append user input to fixed length buffer without checking. We were hardcoding the (correct) max path length in macos.c - replaced by the actual OS constant. But the vast majority are just extremely generous guesses how long localized strings could possibly be. Yes, this commit is likely leaning towards overkill. But we have now been bitten by buffer overflow crashes twice that were caused by localization, so I tried to go through all of the code and identify every possible buffer that could be affected by this.

2013-02-08Fix Uemis downloader to download all matching dive infomrationGravatar Dirk Hohndel
The Uemis SDA returns the data for each dive from several different databases. And oddly, the getDive data uses a different key than the getDivelog data. We have always compensated for that by looking up the correct key and applying the data to that dive, but unfortunately we didn't adjust the loop to correctly retrieve the getDive data for the dives that were downloaded. So depending on how big the offset between those two keys was we wouldn't get all of the necessary data. With this change we try one, calculate the offset and then restart the loop. Insane, but appears to be the only way to make this work. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2013-02-04Fix minor translation tool issue in Uemis downloaderGravatar Dirk Hohndel
If any component of the suit information downloaded from the Uemis SDA is "" we would replace that by the POT information when running the software in a different locale. So only add this text (and translate this text) if it is != "". Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2013-01-30Massive cleanupGravatar Dirk Hohndel
Mostly coding style and whitespace changes plus making lots of functions static that have no need to be extern. This also helped find a bit of code that is actually no longer used. This should have absolutely no functional impact - all changes should be purely cosmetic. But it removes a bunch of lines of code and makes the rest easier to read. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2013-01-29Add missing strings for translationsGravatar Dirk Hohndel
Mostly in new code, but some of them are strings in older code that have been missed in the past. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2013-01-23Move more dive computer filled data to the divecomputer structureGravatar Linus Torvalds
This moves the fields 'duration', 'surfacetime', 'maxdepth', 'meandepth', 'airtemp', 'watertemp', 'salinity' and 'surface_pressure' to the per-divecomputer data structure. They are filled in by the dive computer, and normally not edited. NOTE! All actual *use* of this data was then changed from dive->field to dive->dc.field programmatically with a shell-script and sed, and the result then edited for details. So while the XML save and restore code has been updated, all the displaying etc will currently always just show the first dive computer entry.

2013-01-23Ensure each dive has its own copy of the location text (UEMIS importer)Gravatar Dirk Hohndel
Since multiple dives can reference the same divesite we need to do the strdup when the value gets assigned, not when it gets passed into the helper function. This also validates the location string as on my divecomputer there is an invalid divespot 0 that has a corrupted UTF8 string as location name. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2013-01-18Improve handling for old XML files in Uemis downloaderGravatar Dirk Hohndel
In order to work in the most expected ways for people who have used a version of Subsurface that didn't store the deviceid in the divecomputer we relax the testing for when a divecomputer entry is assumed to match the current divecomputer. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2013-01-18Consistently use uint32_t for deviceidGravatar Dirk Hohndel
There were a handful of places that incorrectly used signed values for the deviceid. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2012-12-29Make sure the model is non-NULL before comparing with itGravatar Dirk Hohndel
In commit 194a05b18911 "Correct the detection of existing dives in the Uemis downloader" I forgot to add that check before calling strcmp. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2012-12-28Don't store notes that are just one space on the UemisGravatar Dirk Hohndel
Sometimes the Uemis appears to return " " as notes instead of no notes. This patch filters this out (otherwise redownloading divecomputers can cause silly things like notes that say "(existing note) or ( )" ) Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2012-12-28Correct the detection of existing dives in the Uemis downloaderGravatar Dirk Hohndel
This didn't take multiple divecomputers into account and didn't compare the model as well as the deviceid to match a divecomputer. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2012-12-07Fix potential uninitialized readGravatar Dirk Hohndel
When analyzing the buffer that is handed to the first_object_id function we carefully check to make sure that we don't read past the end of the input buffer but there was still one code path that could have us do just that. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2012-12-05Fix retrieval of object_id value in Uemis downloaderGravatar Dirk Hohndel
The existing code could read past the end of the buffer that was handed to it. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2012-12-05Improve reading of extra dive data for UemisGravatar Dirk Hohndel
When starting from the first dive on the dive computer we called getDive for every dive starting with id 0 instead of figuring out which id is actually the first one that we downloaded. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2012-12-05Change Uemis code to use locale indepent floating point parsingGravatar Dirk Hohndel
I clearly forgot about not using atof... now we use the locale safe g_ascii_strtod instead. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2012-12-05Turn latitude and longitude into integer micro-degree valuesGravatar Linus Torvalds
This actually makes us internally use 'micro-degrees' for latitude and longitude, and we never turn them into floating point either at parse time or save time. That said, the Uemis downloader internally does still use atof() when converting things, which is likely a bug (locale issues and all that), but I'll ask Dirk to check it out. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2012-12-05Pick up dive numbers from Uemis SDA when starting with empty data fileGravatar Dirk Hohndel
This is improving a bit more on commit d2dd0eb39efe "When starting with an empty data file and downloading dives, number them" by providing a better starting number when a user downloads dives from a Uemis SDA into an empty data file. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2012-12-04Change Uemis debug code to test for bit valuesGravatar Dirk Hohndel
This way individual pieces can be turned on and off. The commit also adds code to read from a disk image (instead of the SDA) without all the long timeouts. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2012-12-01Small cosmetic cleanups of Uemis downloader codeGravatar Dirk Hohndel
Just improving the messages a user gets. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2012-12-01Fix stupid error in last minute cleanup of Uemis rewriteGravatar Dirk Hohndel
Never make trivial changes without testing them. This was missung a '!' before the strcmp - so the wrong code got executed when trying to get the DeviceId and everything afterwards failed without a valid DeviceId. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2012-11-30Convert Uemis downloader to directly create divesGravatar Dirk Hohndel
The initial downloader reused the XML parsing of SDA files that was implemented early in order to support the information extracted from the SDA with the java applet. But creating this intermediary XML file and handing it off to the XML import function always seemed like an ugly way to do things. This became even more obvious when adding more features to the Uemis downloader. This commit completely changes the downloader to instead create dives and record them directly. This also adds support for divespots (which are stored in a seperate database that needs to be queried after the divelog and dive entries have been combined - the Uemis firmware clearly was written by monkeys on crack - oh wait: I'm trusting these same people to get the deco right?). This commit leaves the SDA import capability in the XML parser intact. I'll remove that later. Because of this it actually adds a few lines of code, but the overall change will be a substantial code deletion. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2012-11-28Track Uemis last dive downloaded on a per data-file basisGravatar Dirk Hohndel
Actually, it's even better than that. Thanks to the new divecomputer datastructure we can now simply look up in the dive_table which dives have been downloaded from this specific Uemis SDA. This patch removes the old gconf based code - which leads to one unfortunate problem: the first time a Uemis SDA owner runs this version of Subsurface against their data file ALL dives will be downloaded again (which may not be a bad thing as we have improved a few other details of Uemis support so now they get their deco information, surface pressure and other data that we have started to support since 2.1). Still, this is not ideal. But I didn't want to keep the legacy code around since this new solution is so much cleaner. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2012-11-20Allow the user to cancel a dive computer downloadGravatar Dirk Hohndel
The code pretended to support this for libdivecomputer based downloads, but it had never been hooked up when the native Uemis downloader was implemented. When I finally decided to close that feature gap I realized that the original code was, shall we say, "aspirational" or "completely bogus" and therefore never worked. So instead of just hooking up the code for the Uemis downloader I instead implemented this correctly for the first time for both libdivecomputer and the native Uemis downloader. In order not to have to mess with multithreaded Gtk development I simply opted for a helper function that fires on a 100ms timeout and have it end the dialog without a response. This way we can run the dialog while waiting for the download to finish, still update the progress bar and respond in a useful manner to the user clicking cancel.

2012-11-19Merge branch 'uemis-downloader-fixes'Gravatar Dirk Hohndel
2012-11-19Fix another off by one error in Uemis native downloaderGravatar Dirk Hohndel
And again buffer_insert contained the blatant bug. The code wasn't copying the trailing '\0' when extending the string, which usually didn't end up blowing up the code (and therefore kept the bug hidden until now) because of the way realloc reused memory - we just had trailing garbage strings. But sometimes we weren't so lucky and the strlen in a subsequent call of buffer_insert would run past the end of the allocated buffer. Oops. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2012-11-19Fix stupid off by one error in Uemis downloaderGravatar Dirk Hohndel
We are accessing offset 24 in an array of length 24. To make things easier for the base64 conversion we just treat this as an off by three error and instead create an array large enough for 27 elements and convert a sufficient number of base64 chars to initialize all of them. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2012-11-19Correctly reset the ANS file number when restarting Uemis downloadGravatar Dirk Hohndel
If we ran out of space on the Uemis SDA during download and the user unmounted, unplugged and replugged the SDA, we need to take care to correctly reset the file number we use for finding the correct ANS file. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2012-11-19Improve Uemis timeout handlingGravatar Dirk Hohndel
Start every step with much longer timeouts (until we get the first response back), but then use shorter timeouts once we have started receiving data. This uses up fewer of the ANS files and allows us to get more dives downloaded before the SDA has to be unplugged to reset communications, yet at the same time it still improves the overall download time.

2012-11-11Add special download modes to force updates from the divecomputerGravatar Dirk Hohndel
This will hopefully not be something we need often, but if we improve support for a divecomputer (either in libdivecomputer or in our native Uemis code or even in the way we handle (and potentially discard) events), then it is extremely useful to be able to say "re-download things from the divecomputer and for things that were not edited in Subsurface, don't try to merge the data (which gives BAD results if for example you fixed a bug in the depth calculation in libdivecomputer) but instead simply take the samples, the events and some of the other unedited data straight from the download". This commit implements just that - a "force download" checkbox in the download dialog that makes us reimport all dives from the dive computer, even the ones we already have, and an "always prefer downloaded dive" checkbox that then tells Subsurface not to merge but simply to take the data from the downloaded dive - without overwriting the things we have already edited in Subsurface (like location, buddy, equipment, etc). This, as a precaution, refuses to merge dives that don't have identical start times. So if you have edited the date / time of a dive or if you have previously merged your dive with a different dive computer (and therefore modified samples and events) you are out of luck.

2012-11-10Ignore last dive read from Uemis when starting with empty divelistGravatar Dirk Hohndel
When the user closes the divelist and starts with an empty file it makes no sense to assume that she only wants to download new dives since the last time dives have been downloaded. So if the current divelist is empty we ignore that information and start from the beginning again. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2012-10-25Expand Uemis Zurich download supportGravatar Dirk Hohndel
With this commit we not only use the getDivelogs command but also the getDive command for each of the dives that was downloaded. Oddly, that makes quite a bit of redundant (and at times slightly contradictory) data available, but also many new things. We now get weight, suit and notes that were stored with a dive in the logbook on the divecomputer. There are a ton more data available that we don't use, yet. For example information about altitude, a decoindex, dive type and dive activity, other equipment information, etc. I still need to decide how much of this I want to make available in Subsurface (and how I want to present this - after all most of this is not available from other dive computers). Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2012-10-11Conversion to gettext to allow localizationGravatar Dirk Hohndel
This is just the first step - convert the string literals, try to catch all the places where this isn't possible and the program needs to convert string constants at runtime (those are the N_ macros). Add a very rough first German localization so I can at least test what I have done. Seriously, I have never used a localized OS, so I am certain that I have many of the 'standard' translations wrong. Someone please take over :-) Major issues with this: - right now it hardcodes the search path for the message catalog to be ./locale - that's of course bogus, but it works well while doing initial testing. Once the tooling support is there we just should use the OS default. - even though de_DE defaults to ISO-8859-15 (or ISO-8859-1 - the internets can't seem to agree) I went with UTF-8 as that is what Gtk appears to want to use internally. ISO-8859-15 encoded .mo files create funny looking artefacts instead of Umlaute. - no support at all in the Makefile - I was hoping someone with more experience in how to best set this up would contribute a good set of Makefile rules - likely this will help fix the first issue in that it will also install the .mo file(s) in the correct place(s) For now simply run msgfmt -c -o subsurface.mo deutsch.po to create the subsurface.mo file and then move it to ./locale/de_DE.UTF-8/LC_MESSAGES/subsurface.mo If you make changes to the sources and need to add new strings to be translated, this is what seems to work (again, should be tooled through the Makefile): xgettext -o subsurface-new.pot -s -k_ -kN_ --add-comments="++GETTEXT" *.c msgmerge -s -U po/deutsch.po subsurface-new.pot If you do this PLEASE do one commit that just has the new msgid as changes in line numbers create a TON of diff-noise. Do changes to translations in a SEPARATE commit. - no testing at all on Windows or Mac It builds on Windows :-) Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

2012-09-27Restructure the Uemis native download buffer codeGravatar Dirk Hohndel
Running under Valgrind showed a couple of silly bugs. Worse, intentionally running into various error scenarios showed that we could get the buffer handling in the raw parsing code to break down - we would fail to process the correctly downloaded files. To make it easier to get this right I restructured the code to collect the XML buffer in a different way - this works much better and has stood up well under testing so far. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2012-09-26Much improved handling of out of memory errors in the Uemis downloaderGravatar Dirk Hohndel
Instead of trying to figure out in the GUI code whether to call the downloader again, the logic was moved into the downloader itself. It now attempts to deal cleverly with running out of space on the dive computer filesystem - and in return is able to process the maximum number of dives (instead of just ten or so at a time). Even on partial reads before a failure we are able to collect the data that was completely transferred and report those dives. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2012-09-26First implementation of native Uemis downloaderGravatar Dirk Hohndel
This includes one major hack that uses a private data structure from libdivecomputer to allow us to show the Uemis Zurich as one computer the user can import from. Once the user has chosen the Uemis we don't use libdivecomputer but our own downloader. Just like in the libdicecomputer case this runs in its own thread and updates the import dialog with progress information. The code also keeps track of the last dive that has been downloaded from a Uemis computer so we only import new dives on subsequent downloads. And since the Uemis Zurich gives us its device id, we make this a "per divecomputer" property for people who dive with multiple Uemis Zurich computers. This uses the debugfile infrastructure to allow easily collecting debugging output - especially on Windows where by default console output is lost. Known limitations: when the Uemis runs out of space (it uses its filesystem for communication with the host computer) we have no graceful way to reset things. This is why the code doesn't try to download ALL dives on the computer but instead download them in increments of ten dives. This clearly needs to be addressed once I understand how to reset the device. The Cancel button of the import dialog isn't correctly hooked up, yet. I still need to figure out how to gracefully shut down a download without potentially hanging the device. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
