* sort: extract partition from quicksort
Extract the partition logic from quicksort into a macro. This allows to
reuse the partition logic for, e.g., the quickselect algorithm.
* sort: implement quickselect
implement Hoare's selection algorithm (quickselect) on the basis of the
already implemented quicksort. Quickselect allows to find the kth
smallest element in a unordered list with an average time complexity of
O(N) (worst case: O(N^2)).
* add quicksort benchmark
Create a top-level benchmarks folder. Add the benchmark implementation
for the quicksort algorithm.
Benchmarks can then be run in the same way as unit tests from the
root folder with:
c3c compile-benchmarks benchmarks/stdlib/sort
Ensure that the URL alphabet for base64 is used with the urlencode
functions (urlencode, urlencode_buffer, urlencode_temp and
urlencode_new) are used. Add a new test.
* Add "sources" support for library manifest
* Add "sources" to library manifest creation
* Add "sources" key to target manifest
* Added fallback for already made libraries
* Remove src/ in library creation
* add changes to releasenotes.md
Fix the base64 decoding. If there's an 'A' character in the encoded
text, the base64 decode function returns an INVALID_PADDING error. The
reason lies in the way Base64Decoder.init tries to find a suitable
invalid character. Fix this by defining the invalid character as 0xff
(which is already the case for a decoding without padding).
This error has not been caught by the test harness, because no test
contains an 'A' character in the the encoded text yet. Add a new test.
* io: implement MultiReader struct
Implement a MultiReader (InStream) which sequentially read from the
provided readers (InStreams). Return IoError.EOF when all of the readers
are read.
* io: implement MultiWriter struct
Implement a MultiWriter (OutStream). The MultiWriter duplicates its
writes to all the provided writers (OutStream).
* io: implement TeeReader struct
Implement a TeeReader (InStream) which reads from a wrapped reader
(InStream) and writes data to the provided writer (OutStream).
