Set the maximum socket receive buffer in bytes. Specifing 0 will
disable this option. This value will be set to socket file descriptor
using SO_RCVBUF socket option with setsockopt() call.
See GH-487 about the usecase of this option
With --deferred-input=true, aria2 only reads input file to fill active
download slots, while keeping input file open. Meanwhile,
--save-session saves all download info inside memory, but this does
not take into account of unread item in input file. This will lead to
lose input data in saved session file. Also current BufferedFile
implementation used to read/write input/output file take a lock on
Windows. This effectively prevents session serializer from writing
session data to the same file which is still kept open because of
--deferred-input. See GH-493
Use one of the following to provide random bytes:
- Windows CryptGenRandom
- Linux getrandom (syscall interface to urandom, without nasty corner
cases such as file descriptor exhaustion or re-linked /dev/urandom)
- std::device_random (C++ random device, which usually will be urandom)
This also equalizes util::getRandom and SimpleRandomizer (the former
will now use the latter) instead of having essentially two different
PRNG interfaces with potentially different quality.
Closes GH-320
Add and use usedCompilerAndPlatform(). This adds compiler information to
INFO logs and the --version output, and may be helpful when trying to
diagnose/reproduce user-reported problems.
Also make INFO logs include usedLibs() output.
Closes#235
StatCalc creation is moved to MultiUrlRequestInfo. The summary output
is done only when PREF_QUIET is false and it is always to
global::cout(), so remove summaryOut_ and just use global::cout() in
that case. Also use std::unique_ptr for statCalc_ in DownloadEngine.
sessionConfigSetKeepRunning() was removed and SessionConfig has
keepRunning member instead. Signal handlers are now all prepared in
MultiUrlRequestGroup object. Setting SessionConfig.useSignalHandler to
false will avoid signal handler setup.
