This should not affect non-Win32 platforms in any way.
As for Win32 (both MinGW and MSVC), this should hopefully allow for
unpatched compilation. Correct functioning is not yet guaranteed though.
On a way to factoring out OpenSSL support to a standalone file to ease
addition of other crypto libraries support in the future, move helpers
providing SHA1 calculation to crypto-utils.{c,h}. OpenSSL-related
functionality (SHA1 context management) is moved to crypto-utils-openssl.c.
Add new tr_sha1_ctx_t type and functions to be implemented by crypto
backends:
* tr_sha1_init - allocate SHA1 context and and initialize it,
* tr_sha1_update - hash some [more] data,
* tr_sha1_final - finish hash calculation and free the context.
Add new files to CMakeLists.txt (leftover from previous commit) to fix
CMake-based configuration.
On a way to factoring out OpenSSL support to a standalone file to ease
addition of other crypto libraries support in the future, move helpers
providing random numbers/data generation to crypto-utils.{c,h}. OpenSSL-
related functionality (generation of cryptographically strong random
data) is moved to crypto-utils-openssl.c.
Rename functions to follow currently accepted style:
* tr_cryptoRandBuf -> tr_rand_buffer
* tr_cryptoRandInt -> tr_rand_int
* tr_cryptoWeakRandInt -> tr_rand_int_weak
Fix rare case of invalid value being returned from tr_rand_int. Return
value for abs(INT_MIN) may be undefined and thus negative, and so
tr_rand_int will return negative value which is incorrect (out of
requested and expected range).
Using blacklists with Kademlia is not a good idea, which is why we
don't support it in Transmission. However, some people insist on
implementing the support in their own copies, this well-defined
hook ensures that at least they'll do it right.
During shutdown, we can stop DHT almost immediately, but need to leave the announcer running for the DHT tracker event=stopped messages. So it doesn't make sense to keep them on the same periodic timer.
We now try to contact the bootstrap nodes up to six times.
A better solution might be to reattempt bootstrap every half hour
or so. This might be beneficial to people whose connectivity
changes while Transmission is running.
update-version-h.sh tries to use {{{svnversion}}} when possible. But when it's not, it looks through the "$Id:" lines in the source file comments and uses the largest version number it finds. The new files tr-dht.[ch] didn't have the line of its $Id: comment formatted in the way update-version-h.sh expected. tr-dht.[ch]'s $Id: line has been homogenized to be like everyone else's...
