The Windows version of mmap was mentioned in the message to which you replied:  CreateFileMapping In my earlier message, I mentioned how to use this from boost:  Boost::Iostreams already has a mapped_file Source. Sorry, I’ve been so busy lately I’ve been skimming messages and I still can’t keep up. We […]

I think you misunderstand what mmap does?  mmap / CreateFileMapping does not read a file into heap memory: http://en.wikipedia.org/wiki/Mmap I doubt there’s an mmap(2) on Windows.  I’d rather call an existing file copy function than make and test my own.

mmap(2) + memcpy(3) ?  Boost::Iostreams already has a mapped_file Source. If you read it into memory and write it out, it could fail in tight memory situations. I’m looking for something like copyfile(const char* from, const char* to) or copyfile(path from, path to), preferably something in Boost if it has […]

bitcoin ebuilds for gentoo linux 2011.03.02: bitcoin-git-9999 ebuild updated outdated Come to #bitcoin-gentoo on Freenode for latest Try -datadir= Last time I tried $(shell /usr/bin/wx-config), there was immediate hollering about build problems with it.  There wasn’t time to investigate at the time. One problem with $(shell /usr/bin/wx-config) is it will […]

So, as many others, I need to backup wallet.dat. And since this one is on a server, I need it to happen unattended. And because this server is being used by the lottery, I must not shutdown bitcoind. So far I just copy the file over, and do it often […]

Wallet backups and other DB examination are easily possible in a safe, atomic, transactional fashion… if and only if DB_PRIVATE flag is removed.

Quote from: BioMike on August 25, 2010, 18:23:45 I’ve never objected this change/idea, just asking if this was possible and to what extent. What’s wrong with getting informed? 😉 My apologies, your post was indeed a question not a statement. Related posts: Re: Development of alert system Quote from: BioMike […]

Quote from: nelisky on August 25, 2010, 01:28:32 So what kind of warning do admins get from bitcoind? Is there something we can grep from debug.log? Or will rpc calls raise some specific error? Is there a way to locally force this to happen, for unittesting services? getinfo has a […]
