続2：中華linuxゲーム端末でセガサターン

前回、とりあえずメモリリークっぽいというところまでは分かった。ただ、どこでメモリリークしているのかは分からない。

jemallocではプロファイルが取れるようなので取ってみようとした。

jemalloc prof

./configure --host=aarch64-rocknix-linux-gnueabi --enable-prof

でビルドして、

MALLOC_CONF=prof:true

としてみたが、ファイルが取れなかった。リンクしてmalloc_stats_printは動いてそうだが、なぜかファイル出力されない。 

どうやらatexitで登録されている処理が動いてないようだ。YabDeInitとやらの処理の途中でおそらくabortしており、exitされていないという可能性がある。

とりあえず無理やりmenuから何かの操作をしたらexit(-1)するようにしたところファイルは出力された。

このファイルをみるためjeprofを動かさなければならないが、perlは入ってない。PCで動かそうにもarmのものなのでシンボルが読めなそう。textファイルなので直接読んでみる。

 t何とかで出ているのはおそらくメモリサイズだろう。とりあえず多そうなのは、以下。

16進数はおそらくプログラムの位置だろう。addr2lineで見てみる。

ygles.c:2170は以下のあたり

   if ((program->currentQuad + YGL_MAX_NEED_BUFFER) >= program->maxQuad) {
     program->maxQuad += YGL_MAX_NEED_BUFFER*32;
    program->quads = (float *)realloc(program->quads, program->maxQuad * sizeof(float));
      program->textcoords = (float *) realloc(program->textcoords, program->maxQuad * sizeof(float) * 2);
      program->vertexAttribute = (float *) realloc(program->vertexAttribute, program->maxQuad * sizeof(float)*2);
    YglCacheReset(_Ygl->texture_manager);
   }

currentQuadが増えたらメモリを取り直している。なにかで増えたら増えていく模様。

なんとなく原因は分かったが、どうやって直せばいいのか？どういう作りなのか理解しないと直せなそう。 

とりあえずここまで。 

追記：

上記を無理やり開放するようにして動かしてもメモリが増える現象は変わらなかった。currentQuadは毎回0にされており、無限に増えていくわけではなさそう。どうやらテクスチャの最大必要なところまで拡大する処理のように見える。

ピークを引きずっているわけなので、いつまでもそれだけ確保し続けるのもちょっと困りものだが、とりあえず今回の原因ではなさそう。ここ以外でメモリ消費で大きいものを探すと以下だった。

ダイナミックリコンパイルのあたり？っぽい。OpenGL関係でリークしているのかと思って探し回っていたが予想外。

うーん。 確保されてても解放されてて問題ないのだろうか。t0とかの意味が分からない。
