There's no guarantee that gtk is thread-safe (apparently it can be
broken at least on Windows, even though it should be fine on top of X).
So don't update the progress bar directly from the dive computer import
code, instead just update the progress information in static variables,
and let the GUI thread update it while it does the idle loop polling
anyway.

[ I really wanted the utc_mkdate/mktime functions to use proper years,

things with "localtime()" in one place, so for now we have to be
compatible with the insane tm_year semantics. - Linus ]

Merge the dive trip rewrite by Dirk Hohndel.
This just merges the dive trip changes with the timestamp handling
changes. There were multiple small data conflicts, along with some
newly added 'time_t' cases in the dive trip handling that needed to be
converted to 'timestamp_t' along the way.
* 'divetrip-rewrite' of git://github.com/torvalds/subsurface:
Convert FIND_TRIP into function
Partial rewrite of the dive trip code
Check if trip is NULL before calling DIVE_TRIP
Merge the 64-bit timestamp_t time function branch.
This makes subsurface not only safe against the 2038-year problem, but
also avoids the use of thread-unsafe gmtime() etc.
We still use the system time_t for initializing the calendar widget for
adding a new dive, but that's cosmetic rather than anything fundamental.
* time-function:
FIND_TRIP: don't cast a timestamp to a pointer
dive-time widget: fix incorrect use of timestamp_t
Fix the incorrect data type for DIVE_DATE accesses
Use a 64-bit 'timestamp_t' for all timestamps, rather than 'time_t'
The pointer size may not be large enough to contain a timestamp, so make
FIND_TRIP() just pass the pointer to the timestamp instead.
And use an inline function instead of macros with casts. That gets us
proper type safety while at it, so that we get a warning if somebody
doesn't pass the expected "timestamp_t *". Plus the code actually looks
simpler and way more straightforward.
Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
I did a global search-and-replace to make all "time_t" users use the
internal subsurface 64-bit "timestamp_t" type instead, but we have one
case that still uses the system time functions: the use of "localtime()"
in the dive_time_widget().
Everywhere else we always just use UTC for all our time handling, and we
don't really ever care about the local timezone etc. However, for the
dive time widget, we initialize the calendar widget to the current time,
which obviously does want to take the local timezone into account, so
there we end up using the whole system time handling code.
So that one should continue to use time_t, even if it might have the
year-2038 problem. We also don't care about the fact that it's not
thread-safe, since this is just initializing the widget which definitely
doesn't happen threaded.

This helps us deal with the issue that the g_list convenience functions
don't allow us to easily compare 64bit values on 32bit architectures. And
since these convenience functions are truly trivial in nature, it seemed
easier to simply implement our own logic here.
In the process I moved all the dive_trip_list helper functions into the
same spot in divelist.c
Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
This is the same bugfix that Lubomir did in the master branch, but now
on top of the new 64-bit timestamp_t model. So now we also remove the
comment about the year 2038 problem, because it's not true any more. We
do all the date handling in a 64-bit integer.
Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
This introduces a new data structure for dive trips - reuseing the struct
dive just got way too messy.
The dive_trip_t datastructure now allows the code to remember if the trip
was auto generated or if its time stamp changed when dives where added to
the trip during auto generation.
The algorithm also distinguishes between dives that were intentionally
added to a trip (either in an XML file or by adding them to trip in the
UI) and dives that were added to trips via autogen. Saving dives that were
added to trips via autogen makes that assignment "intentional".
With this partial rewrite several of the oddities of the old code should
be resolved - especially turning autogen on and off again should get the
divelist back to the previous stage.
Also, when dives are merged during file open or import we now try to pick
the correct tripflag (instead of just ignoring the tripflag completely and
resetting it to TF_NONE by mistake).
Finally, the dive trip debugging code got more verbose and is trying
harder to detect issues at the earliest time possible.

The type of the DIVE_DATE field is G_TYPE_LONG, so when accessing it we
have to pass gtk_tree_model_get() the proper "long *" pointer, rather
than an int. On 64-bit platforms, passing a pointer to an int would
otherwise result in randomly overwriting another four bytes of stack.
Sadly, there are not much safety checks to warn if our passed variable
to the vararg list is of the correct type, which is unlike
gtk_tree_model_get_value(), which will report typed errors.
This solves a bug that may potentially result in undefined behaviour
on some x64 OS (e.g Ubuntu 12.04 x64).

This makes the time type unambiguous, and we can use G_TYPE_INT64 for it
in the divelist too.
It also implements a portable (and thread-safe) "utc_mkdate()" function
that acts kind of like gmtime_r(), but using the 64-bit timestamp_t. It
matches our original "utc_mktime()".

Thanks to Christian for running the static code analysis tool against
subsurface...
There were some false positives, a few style issues that I'll ignore for
now, and two actual potential bugs.
First: Don't check unsigned variables for < 0
This has been around for a while and we are lucky that while technically a
bug it still works as expected. Passing a negative idx simply turns it
into a very large unsigned integer which then fails the > dive_table.nr
test. So it still gets a NULL returned. A bug? Yes. Critical? No.
Mismatched allocation and free
This is an actual bug that potentially could cause issues. We allocate
memory with malloc and free it with g_free. Not good.

Commit cdae2869d1dd ("Show the datafile name even with no dives") was a

Several potential problems.
- we could end up dereferencing exiting_filename when it was NULL
- we could free the default_filename by mistake -
subsurface_default_filename always needs to return a copy of it
- closing the existing file before opening a new one repopulated the
existing_filename with the default filename - preventing the opened
file to become the new existing filename
Also, make existing filename a const char * and make file_open have the
same sensible default folder behavior as the other file related functions.

One of the limitations of GtkFileChooserButton is that it only allows one
file to be chosen (so that it can display that file name in the button
after the file chooser dialog finishes). Since in the import dialog we
never want to show the button with the filename(s) filled in but want to
directly execute the import once files have been selected, I reimplemented
the button to simply open a multi file chooser when clicked and to then
run the import function if one or more file names were selected.
This does appear to require some more code but gets us a much more useful
and consistent implementation.
Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
This should make things more consistent, especially now that "Open"
actually does just that and no longer behaves almost like "Import".
The downside is that the import from a dive computer is now in the File
menu as well and no longer in the Log menu, where Linus originally had
moved it to in commit 3cace090989b.

This is a pretty significant semantic change - Open used to act more like
Import; you added more dives to the divelist. With this change it instead
acts more like the traditional File->Open in that it closes the previous
file, first.
The diff hides the minimalistic nature of the change - it seemed cleaner to
move the file_open function around than to do a forward declaration of
file_close.
