66f1b4408c never use tiff memcpy mode for ycbcr images 
We were still using memcpy mode for some strip YCbCr images. Clean up
read var naming to make the logic easier to follow.

1f100c0c42 better buffer sizing in tiff reader 
We were not setting JPEGCOLORMODE_RGB early enough, so buffers could be
undersized in some circumstances.

Thanks omira-sch.

- remove dead base64.h
- add an assert for overflow

33d90b5e26 only enable sanity checks in debug mode 
We had a couple of sanity checks always on. As a result, libvips could
get slow for large pipelines.

Move them into g_assert().

Merge pull request #1240 from jtorresfabra/fix_hidden_threapool_leak 
Fix for hidden leaks in ThreadPool
 2019-02-27 13:41:17 +00:00
jtorresfabra
8c8affab7f ThreadPool was allocating memory for threads and pools locally to the image object. As that image could not be freed from cache, for each sink operation done for that image the code was creating new pools and threads without freeing the previous one. SO the more number of threads and the more operations the bigger the hidden leak was. The fix just creates the objects not locally to that image, and also free them in its destroy functions 2019-02-27 13:01:45 +01:00
