From 088c42c5c3cb34bac98fce95e4f3d08642834112 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Wed, 2 Jul 2008 17:08:09 -0600 Subject: mesa: fix error codes in _mesa_shader_source(), _mesa_get_shader_source() If the 'shader' parameter is wrong, need to either generate GL_INVALID_VALUE or GL_INVALID_OPERATION. It depends on whether 'shader' actually names a 'program' or is a totally unknown ID. There might be other cases to fix... cherry-picked from master --- src/mesa/shader/shader_api.c | 14 ++++++++++++-- 1 file changed, 12 insertions(+), 2 deletions(-) (limited to 'src/mesa/shader') diff --git a/src/mesa/shader/shader_api.c b/src/mesa/shader/shader_api.c index a005c902e1..26d0b3d476 100644 --- a/src/mesa/shader/shader_api.c +++ b/src/mesa/shader/shader_api.c @@ -875,7 +875,12 @@ _mesa_get_shader_source(GLcontext *ctx, GLuint shader, GLsizei maxLength, { struct gl_shader *sh = _mesa_lookup_shader(ctx, shader); if (!sh) { - _mesa_error(ctx, GL_INVALID_VALUE, "glGetShaderSource(shader)"); + GLenum err; + if (_mesa_lookup_shader_program(ctx, shader)) + err = GL_INVALID_OPERATION; + else + err = GL_INVALID_VALUE; + _mesa_error(ctx, err, "glGetShaderSource(shader)"); return; } copy_string(sourceOut, maxLength, length, sh->Source); @@ -966,7 +971,12 @@ _mesa_shader_source(GLcontext *ctx, GLuint shader, const GLchar *source) { struct gl_shader *sh = _mesa_lookup_shader(ctx, shader); if (!sh) { - _mesa_error(ctx, GL_INVALID_VALUE, "glShaderSource(shaderObj)"); + GLenum err; + if (_mesa_lookup_shader_program(ctx, shader)) + err = GL_INVALID_OPERATION; + else + err = GL_INVALID_VALUE; + _mesa_error(ctx, err, "glShaderSource(shaderObj)"); return; } -- cgit v1.2.3
