* QRingBuffer::reserve(): remove superfluous assertAlex Trotsenko2016-10-221-1/+0
| | | | | | | | 'bytes' is checked against MaxByteArraySize in the beginning and remains unchanged in the function. Change-Id: Ibd4091b95837db16cf45f845d485bfb189317125 Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>
* QRingBuffer: add packet modeAlex Trotsenko2016-07-231-22/+24
| | | | | | | | | | | As a special case, setting the value of chunk size to zero forces QRingBuffer to produce a separate QByteArray on each call which appends the data. So, this enables a packet mode where portions of data are stored independently from each other.

* CoreLib: use const (and const APIs) moreAnton Kudryavtsev2016-04-181-6/+6
| | | | | | | | | | For CoW types const methods will be called. Mark store_persistent_indexes() as const, because this method does not modify the object. Change-Id: Ic867913b4fb5aaebfbaaffe1d3be45cf7b646403 Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>

* Unify QByteArray::MaxSize and MaxAllocSizeUlf Hermann2015-06-161-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | We have established the maximum size qAllocMore can deal with in commit 880986be2357a1f80827d038d770dc2f80300201 and we should use it. The maximum size for byte arrays is reduced by one byte as with the previous code we could make qAllocMore produce ((1 << 31) - extra) by passing (1 << 30). That is not a problem for qAllocMore itself (as long as extra > 0) but it's hard to verify that no related code casts the total sum back to signed int, which would overflow to -1. To make the compiler inline access to the maximum size, a private enum MaxByteArraySize is provided, which can be used in internal code. This fixes the merge of commits 880986be2357a1f80827d038d770dc2f80300201 and c70658d301e274c3aaa1fb6cebe2a5e56db12779 Change-Id: Idb04856f7c2e53ef383063e7555d3083020ff2b7 Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>
