Resolve several compile warnings when comparing different int signedness #1755

alsed · 2024-12-20T00:13:41Z

advances #713 and eliminates several compilation warnings concerning comparison between integers of different signedness.

this resolve a compilation warning about comparison of expressions wih different signedness.

this avoid compilation warnings about comparison expressions of different signedness.

- resolves a compilation warning about comparison expressions of different signedness. - setupstyle() uses getcurrentstylename() to retrieve name. - correction in the message log.

- resolved a comp warning about comparison of different signedness - new function created: calculate_packed_xz(), used by const CPosition& CLevelGraph::vertex_position() and bool CLevelGraph::inside() - aditional minor resolves

…dness - resolves a warning compilation in ConvertTextureFormat(), modified to a for loop range, this avoid integers comparisions. - resolves warnings when int comparing with unsigned macro R__NUM_SUN_CASCADES, in render_phase_sun.cpp. - resolves warnings when int comparing with unsigned macro R__NUM_PARALLEL_CONTEXTS, in r2_loader.cpp - var "b_count" converted to unsigned to resolve warnings within for loops, in AnimationKeyCalculate.h - resolves warnings when for loops compare signed vs unsigned, in r__sector.cpp

…ness (2) - advances OpenXRay#713 and eliminates all warnings concerning this operation: - in R_dsgraph_structure::load() / r__dsgraph_build.cpp - var 'vcnt' converted to u32 in R_Backend_DBG.cpp - several for loops in light.cpp - several for loops in in DetailManager_CACHE.cpp - var 'filled_blocks' converted from int to i32, in SoundRender_Emitter.cpp - in CSoundRender_Core::create() / SoundRender_Core.cpp, explicit convertion of var 'sg_SourceType' to int - for loop in CollectorPacked::CollectorPacked() / xrCDB_Collector.cpp - several for loops in Frustum.cpp

LGTM!
I didn't checked xrAICore and xrSound yet.
The main thing to correct here is replace unsigned int with u32.

On Windows process_id variable has DWORD type and GetCurrentProcessId() returns DWORD too.
On Linux this variable has type pid_t and GetCurrentProcessId() is a macro to getpid function that returns pid_t.

Why does it throw a warning here??

As with all the changes in this commit, the warning is for comparing a signed int with an unsigned.

Edit:
Is for pid_t :

warning: comparison of integer expressions of different signedness: ‘u32’ {aka ‘unsigned int’} and ‘__pid_t’ {aka ‘int’} [-Wsign-compare] 869 | if (CL->process_id == GetCurrentProcessId()) | ~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~``

Try this. Will it fix the warning?

Suggested change

if (CL->process_id == static_cast<u32>(GetCurrentProcessId()))

if (CL->process_id == static_cast<xrpid_t>(GetCurrentProcessId()))

The warning persist, xrpid_t is consider an int.
How about converting process_id to int for this comparison? unsigned to signed should be safer
if (static_cast<int>(CL->process_id) == GetCurrentProcessId())

Changes requested already made.
I'm thinking I should change all unsigned int to u32 since that's what they really are comparing to... let me know if I proceed.

The last 2 warning regarding this (not included in the commit yet) are these:

/xray-16/src/xrCore/LocatorAPI.cpp:362:30: warning: comparison of integer expressions of different signedness: ‘ssize_t’ {aka ‘long int’} and ‘size_t’ {aka ‘long unsigned int’} [-Wsign-compare]
  362 |             VERIFY(read_byte == dwSize);

/xray-16/src/xrCore/string_concatenations.cpp:111:33: warning: comparison of integer expressions of different signedness: ‘u32’ {aka ‘unsigned int’} and ‘int’ [-Wsign-compare]
  111 |     VERIFY(overrun_string_index != -1);

I'm not sure the best way to resolve them, but we can do it and eliminate all.

Also, added fixes for Images.cpp

src/xrAICore/Navigation/level_graph_inline.h

src/xrSound/SoundRender_Core.cpp

src/xrSound/SoundRender_Emitter.h

- all `unsigned int` changed to `u32` - on SoundRender_Emitter.h - var `filled_blocks` reverted to `int` as requested. - reverted changes to `level_graph_inline.h` - proposal for `Server_Client_Check()` on `xrServer.cpp`

I'm only unsure about this, but whatever. It can be changed later, if needed.
