jknockaert f5415653fd fix #15973
Rework of stream_seek handling; there where basically two bugs: 1. seeking to the end of the current file would fail (with SEEK_SET); and 2. if seeking to an undefined position (outside 0,unencryptedSize) then newPosition was not defined. I used the opportunity to simplify the code.

jknockaert 735f6cc037 fix encryption header error
When moving back the pointer to position 0 (using stream_seek), the pointer on the encrypted stream will be moved to the position immediately after the header. Reading the header again (invoked by stream_read) will cause an error, writing the header again (invoked by stream_write) will corrupt the file. Reading/writing the header should therefore happen when opening the file rather than upon read or write. Note that a side-effect of this PR is that empty files will still get an encryption header; I think that is OK, but it is different from how it was originally implemented.

Vincent Petry 76dad297ff Fix encryption feof to not return too early
This is because stream_read will pre-cache the next block which causes
feof($this->source) to return true prematurely. So we cannot rely on it.

Fixed encryption stream wrapper unit tests to actually simulate 6k/8k
blocks to make sure we cover the matching logic.

Added two data files with 8192 and 8193 bytes.

Bjoern Schiessle 67500d5f2f if we start writing a file from the beginning, size should start by zero; result of floor needs to be casted to int in order to compare it with ->size 2015-04-16 14:15:04 +02:00
