The stores it's text in the key_lines array which is NUM_KEY_LINES *
MAXCMDLINE chars long. The code never checked for overflows, it just
assumed that a line will never be longer then 256 chars * 8 = 2048
pixel. With modern displays we can have higher vertical resolutions,
so the array will overflow sooner or later.
Fix it by clamping the maximum line width to MAXCMDLINE - 2 chars (1
for the prompt and 1 for the terminating \0). While at it increase
MAXCMDLINE to 1024 chars * 8 = 8192 pixel, which is more then 8k
resolution and should be enough for the years to come.
This is belived tot fix at least a part of issue #368.
This is a very first cut:
* It compiles
* It doesn't crash
What's missing:
* cmake integration
* CURL should be loaded dynamically
* Integration between download code and filesystem
* Likely UTF-8 stuff
* cl_http.c needs cleanup
* Windows support
On Unix platforms unicode is implemented through UTF-8 which is
transparent for applications. But on Windows a UTF-16 dialect is
used which needs alteration at application side. This wrapper is
another step to unicode support on Windows, now we can replace
fopen() by a function that converts our internal UTF-8 pathes to
Windows UTF-16 dialect.
This is a noop for Unix platforms. The Windows build is broken,
the compiler errors out in shared.h. This will be fixed in a
later commit.
Caveats:
* fopen() calls in 3rd party code (std_* and unzip) are not replaced.
This may become a problem. We need to check that.
* In the Unix specific code fopen() isn't replaced since it's not
necessayry.
The old framecounter had two problems:
* It measured only the time of the current render frame, not the total
time spend between the last and the current render frame. Therefor the
calculated value was too high.
* It was based upon milliseconds and rather inaccurate.
This new frame counter solves both problems. The total time spend
between two render frames is measured and the measurement done in
microseconds.
There're three modes:
* cl_drawfps 1 displayes the average frame rate calculated over the last
60 frames.
* cl_drawfps 2 displays a nice string with minimal framerate, maximum
framerate and average framerate. All three values are calculated over
the last 60 frames.
* cl_drawfps 3 is the same as number 2 but with a second line showing the
raw values.
TODO:
* Discuss if cl_drawfps should be renamed to cl_showfps. All other
status displays are named cl_show*.
While at it remove several unsused drawing functions.
When the client is paused (either explicit or by entering the menu or
console) the cinematic is paused, too. Therefor no more sound samples
are generated and added to the playback queue, the existing samples are
played over and over again. Until now these samples weren't hearable,
because OpenAL marked them as processed and AL_StreamUpdate() removed
them from OpenALs playback queues. This changed in the previous commit,
now the stay in OpenALs queue and are hearable.
Fix this by calling AL_UnqueueRawSamples() when the menu or console is
entered during cinematic playback.
Con_DrawConsole() assumed that the version string was always 21chars
long, we changed it to allow longer strings with other lenghts.
In Unix main() we changed the code for underlining
"Yamagi Quake II $version" with === so the underlining is as long
as the underlined string.
it's saved in $HOME/.yq2/$mod/history.txt
While I was at it, I made the max number of lines in the history
configurable at compiletime by introducing a NUM_KEY_LINES #define
Newer jpeg versions (I guess starting with 9) define an macro
"VERSION", colliding with ours. While wie could #undef it, take
the less hacky route and rename it.
Revert "change several strcat calls to Q_strlcat calls"
This reverts commit ab879f1bc7.
Revert "change (v)sprintf calls to (v)snprintf calls"
This reverts commit b46e210d76.
Using a float number as version number is a bad idea. Correct this long
standing problem by changing it to a string. If we ever want to compare
version numbers, 2 integer constants "MAJOR_VERSION" and "MINOR_VERSION"
should be added.
