This release is made for Niels Thykier and apt-file.

Refactor InternalReadLine to not unroll Size == 0 case2015-12-26T21:46:04ZJulian Andres Klodejak@debian.org2015-12-26T21:23:43Zurn:sha1:01152444ba96051fa0ca90b08dcbb8fec9d81745
There is not much point and this is more readable.

Change InternalReadLine to always use buffer.read() return value2015-12-26T21:46:04ZJulian Andres Klodejak@debian.org2015-12-26T21:06:14Zurn:sha1:a9024b1be2e26c3c6b1f67093ddbf7602636ec9f
This is mostly a documentation issue, as the size we want to
read is always less than or equal to the size of the buffer,
so the return value will be the same as the size argument.
Nonetheless, people wondered about it, and it seems clearer
to just always use the return value.
apt-helper: Add a cat-file command for concatening files2015-12-26T20:48:14ZJulian Andres Klodejak@debian.org2015-12-26T20:45:32Zurn:sha1:2658e1c5487d0bb9c6223cf149a48f47e8d10b4d
This can automatically handle compressed files and is useful
for stuff like apt-file.

This further improves our performance, and rred on uncompressed
files now spents 78% of its time in writing. Which means that
we should really look at buffering those.
rred: Allow passing files as arguments for compressor testing2015-12-26T14:29:00ZJulian Andres Klodejak@debian.org2015-12-26T14:25:33Zurn:sha1:46cddb8c1a393cc7d03fbd897f2504ae9f47179d
This introduces a -t mode in which the first argument is input,
the second is output and the remaining are diffs.
This allows us to test patching compressed files, which are
detected using their file extension.
Use a hardcoded buffer size of 4096 to fix performance2015-12-26T13:49:00ZJulian Andres Klodejak@debian.org2015-12-26T13:49:00Zurn:sha1:0b29c72bdfc1466d47567cc3191b9661f81d3d3f
The code uses memmove() to move parts of the buffer to the
front when the buffer is only partially read. By simply
reading one page at a time, the maximum size of bytes that
must be moved has a hard limit, and performance improves:
In one test case, consisting of a 430 MB Contents file,
and a 75K PDiff, applying the PDiff previously took about
48 seconds and now completes in 2 seconds.
Further speed up can be achieved by buffering writes, they
account for about 60% of the run-time now.
