This adds a mechanism for running generic operations at specific points
of the frame execution. This can be used by any part of the code an not
just Lua since it simply executes std::functions. It also adds an
"execution context" concept that specifies in which situation an
operation should be executed.
This is then used by the Lua Coroutines code for resuming coroutines at
specific points instead of always when the awaited promise resolves.
This adds the capability to have a Lua script that does not need to use
our table syntax at all but instead defines the hooks by calling API
functions. This also makes it possible to add hook functions at runtime
if the script requires that.
Also clean up some unused debug stuff.
Since FSO does not support Unicode characters in filesystem paths on
Windows yet, it is necessary to catch these issues early on and display
an appropriate error message. These changes do that by going through the
path with our UTF-8 decoder and detecting any characters that are out of
the ASCII range.
The intent behind this sort (added in #2094) was to make the order of files returned by the filesystem consistent across platforms; however, the sort occurred not only after the filesystem search, but after the packfile search, which changed the order files load in on all filesystems instead of making it consistent. This moves the sort to be after the filesystem search but before the packfile search, hopefully making load order consistent once more.
When running a mod on non-windows, that isn't packed into VP files, the
mod can break when loading. On non-windows filesystems, the file
order isn't guaranteed to be alphabetical (but it is on Windows).
As a result, we load tables in an effectively random order.
Lots of mods rely on the filesystem ordering to e.g. implement a very
loose dependency system for their lua scripts.

Instead, always sort filesystem listing by name *before* applying the
provided sort order.
I've built a few different versions of this patch, and like this one the
best. The other ones I tried:
1. Adding a `CF_SORT_REVERSE_NAME` and using it everywhere that
`CF_SORT_REVERSE` is used, and replacing all uses of `CF_SORT_NONE` with
`CF_SORT_NAME`. I didn't like this as it was a much larger diff.
2. Adding a `CF_SORT_REVERSE_NAME` to the `scripting.cpp` call for
loading tables. I didn't like this one because this bug can in theory
impact non scripting tables.
Here's a log from Solaris working with the new build:

While it might be a reasonable enhancement in the future to build a proper dependency system for lua scripts and tables,
this is a much smaller and easier change, and doesn't require any work from modders.
The only thing a CFILE contained was a version field which isn't used
anymore so that could be removed which basically meant that CFILE was
just an indirection to a Cfile_block which I then just renamed to CFILE.
The CFILE type is an opaque handle now since the contents are not
relevant to a user of Cfile.
This adds some auto-closing code to the scripting API of the CFile
system. If a file has to be auto-closed then an error will be displayed
to let the the script writer know that something is wrong.
This should not break existing scripts since causing file handle leaks
should never happen and if it does, this will make it easier to find
these issues.
This changes the pilot reading code to always use JSON files for storing
the pilot data. Old pilots are converted to the new format when FSO
starts and after that point only JSON pilots will be used.
The amount of output parameters is becoming quite large which makes it
harder to add new input parameters. For that reason I converted the
existing output parameters to a struct which cleans up the function
signature a lot.
This allows to directly display RGB(A) movies without transcoding them
to YUV first. This allows the movie player to support APNG files (which
are supported natively by FFmpeg) with an alpha channel and without
converting them to YUV first.
This can be used for mark parts of the code which should be unreachable
in normal execution. In debug mode, if such a statement is reached an
Error dialog is shown which aborts the execution. In release mode the
macro is replaced with a compiler specific expression that lets the
compiler know that this part is unreachable which allows it to optimize
the code better.
This allows to use external subtile files (currently only SRT is
configured) for providing subtitles for movie files. This should be more
universal since it also supports container formats with no support for
subtitle streams.
To use this code the srt file needs to be named
"<movie name>-<language code>.srt" where the language code is the file
extension name specified in the localization table. For english the
"-..." part can be omitted.
There were some reports that using a newer launcher together with an
outdated launcher was causing some issues since the new launcher would
write the new config file which would cause FSO to ignore the changes of
the old launcher since the new config file already exists.
This fixes that by adding a check for when the config locations were
last modified. On Linux and Mac it checks when the old config locations
were modified last while on Windows it checks the registry to determine
if there was a change after the new config file was created.
This fixes various issues I found while trying to compile FSO in a cross
compilation setup using MinGW. This is a prerequisite for merging Tea-CI
support.
This fixes a warning caused by parsing the default ai_profiles table
twice. The default table was moved out of the data/tables folder and
into a special builtin category which will not be included in CFile.
This allows to use more complex file structures in the executable
without requiring that those exist as real files. The rest of the code
does not need to handle the difference between a default file and a real
file anymore which means that it's now possible to embed image files
into the executable since bmpman only needs to use the standard CFile
API.
I added two tests which check if the default file can be found and
opened and if a mod file overrides the default file which should always
be possible.
Invalid values previously corrupted the internal position counter which
caused crashes on some platforms because the position counter would
overflow in the next read operation. I added some assertions to track
the position counter corruption and it's probably a good idea to leave
them in to catch possible future errors early.
The actual fix was to just ensure that the seek position it always valid
for the file.
This fixes#1059.
The flag was previously used to restrict searching of mission files to
the root directory of the mod. Since the SDL merge changed what the
default root directory is (now it's the mod folder in the user folder)
this broke the mission editor and it didn't show any missions anymore.
This fixes that by altering how Skip_packfile_search affects the file
search. Now that causes the search to skip files in VPs but it still
includes all other files that are present on the disk.
I also fixed some inconsistent behavior in the various file enumeration
functions since they weren't doing the same thing.
This changes the original behavior slightly since new files aren't found
in this search since the file list is only initialized when CFile is
started so if a new file is added after that, it is not reflected in the
mission list. Since that is pretty rare we can probably ignore that
here.
This fixes#1224.
Previously, if a mod used an upper case "Data" folder (which is the case
for the Diaspora development files) the file enumeration would fail on
case sensitive platforms (e.g. Linux) since FSO searched for a path with
a lower case "data". These changes make it so that FSO looks for all
instances of the path type name regeardless of case. Since the real path
was also needed elsewhere I added a new cf_file field which stores the
actual path which can then be used by fopen operations.
This fixes#1182.
