Thanks to ~jmjl, I was able to find that pcoin_keys didn't work. To fix it, tcoin uses sneaky magic but with stdin isntead of an argument, and a new library imported called popen2, that lets me send both stdin and receive stdout, to successfully get "ls <path to the pcoin_keys directory>" to work (it execl's another instance of the tcoin comand so that it runs under setuid instead of as the original user who ran it.

Simple logical mistake in checking for the TILDEGURU flag has been corrected in tcoin.cpp
|
| |
|
|
| |
/usr/bin/whoami doesn't give the euid's username, but the uid's on FreeBSD, so did the same thing I did for tilde.institute, but for tilde.guru too and introduced a new flag for it, TILDEGURU.
|
| |
|
|
| |
tilde.guru doesn't have the default group of new files be the 'tilde' group, so the group should be manually changed in the compile_tcoin and compile_pcoin scripts. ntcoin_freebsd_tildeguru creates those scripts, so the changes have been made in that file.

scrypt_freebsd is the FreeBSD-compiled version of scrypt, included here.

/ missing from /usr/local/bin/bash in one place.

Freebsd version of ntcoin, specifically targetting tilde.guru but could work on other default FreeBSD configs.

This is preparing tcoin/pcoin for the automatic registration of program accounts.
Eventually, I want program accounts to be tradeable by there being a way to regenerate a new key.
So, send the current key to whomever you want the program account to be used by, then the new owner regenerates the key
to complete the transfer. The old owner will no longer be able to use the old key to operate the new account. The key is
long and the key generation random enough for key collisions to be virtually impossible.

Improved the way 5 arguments were handled, where the intention was to
send a message along with the amount and receiver, with a new error code
and a slightly modified error message.

Fixed a case of too many arguments in 'tcoin send' that wasn't handled.
Thank you for finding this ~julian.

There were many more places where I had hardcoded values, but
should have used strlen() or sizeof(). I have gone through
tcoin.cpp and pcoin.cpp, found those, and fixed them.
Hopefully, this is all of them.
|
| |
|
|
|
|
|
|
| |
In user_has_initialised(..), the path lengths were hardcoded.
This has now been changed to being calculated via sizeof().
In get_file_value and add_file_value, strlen() was used. This has
also been replaced with sizeof().

Merging changes from the master branch because I forgot to do git pull

I had updated the 'ntcoin' script but had forgotten to change README.md.

Added comment to tcoin.cpp to send the actual error message to
stderr when running exit_program(err_no).

The scrypt binary file's permissions were modified on tilde.town.

Refactored the send function in tcoin and pcoin, and in the process,
fixed a bug in pcoin's silentsend function.

Remove outdated comment

The comment referred to using || instead of &&, despite the fact that the code now uses &&.

This was done so that the date generation changes for OpenBSD and tilde.institute-type systems will apply.
|
| |
|
|
| |
On OpenBSD, the equivalent of %_d is %e. This is fixed for OpenBSD/tilde.institute type systems now.

I was planning to make a change that I did not adequately reverse, so I have reversed it fully now.
The change I was planning to make was to remove references to login@tilde.town on systems that were
not tilde.town, but I decided against that change eventually (but didn't reverse it fully).

1. Custom host name now possible in tcoin --help
2. Changes to ntcoin and ntcoin_openbsd_tildeinstitute to fix a bug in -d/--def.
3. Changes to ntcoin and ntcoin_openbsd_tildeinstitute to check for the correct number of arguments.
4. Changes to ntcoin and ntcoin_openbsd_tildeinstitute to include the host name as a preprocessor constant.
|

|
|
|

1. Removed unneeded WHOAMI_PATH preprocessor constant from pcoin.cpp.
2. Updated WHOAMI_PATH for tilde.institute to use "id -ru" to get the real uid on OpenBSD (/usr/bin/whoami doesn't get the real username on OpenBSD).

Thanks to gbmor, I was able to replace base64 (fourmilab version) (which outputs \r\n and thus interferes with tr -d '\n') with gbase64 (the GNU coreutils version) which only outputs '\n'.
|
| |
|
|
| |
Removed references to realpath.c, which is no longer included. Added a few more requirements to the README.md for "ntcoin" to run.

I have created a version of ntcoin that works on tilde.institute's OpenBSD system. I suppose I have to make ntcoin better by using something like make and more POSIX-compliant.
|
| |
|
|
| |
It wasn't useful.
|

Updated README.md to include some dependencies for running "ntcoin".
|

|

Changed first line of description to match Github's description.
|
| |
|

I forgot that base_amount held the number of centitildecoins, and that I had to use cout_formatted_amount() to actually send to stdout the number of tildecoins (with decimal places).
|
| |
|
| |
I forgot to type "help(" and had just typed "void long long int base_amount)".
|
| |
|
| |
Brought to my attention by ~mastergeek on tilde.team, the tcoin help incorrectly said that the number of tildecoins a user started with was 1000. It was actually the current base amount (unaltered by other sources like minercoin, tildebot or daily-adventure). Now, the help shows the right amount of starting coins.

Thanks to ~lickthecheese on tilde.town, tilde.team and other tildeboxes, I was informed of this typo: 'creata' -> 'create'

And I don't know how to clean my commits after having pushed
them to remote origin/master. Maybe a Git stash and hard reset?

TCOIN_MSG_LENGTH_LIMIT
I made a switch from TCOIN_MSG_LENGTH to TCOIN_MSG_LENGTH_LIMIT for the symbolic constant
representing the maximum number of characters of a transaction message. I changed all instances
of the symbolic constant to this new name in tcoin.cpp, but forgot to do it in one instance in
pcoin.cpp. This goes on to show that I need to develop tests for tcoin and pcoin, as well as
start using getopt from util-linux for proper options handling.

After having received a 10000-character transaction message from ~jan6@envs.net,
I finally came around to implementing character limits on transaction messages.
Previously, I was of the opinion that one should be able to send a movie as a
transaction message if one so wished.
I took inspiration for an appropriate character limit from Australia's NPP (New
Payments Platform), which has a 280-character limit on transaction messages. I
strongly suspect this limit came from Twitter's analysis of tweets in different
languages and Twitter research that concluded that a 280-character tweet was the
appropriate length of tweet. A transaction message is supposedly like a tweet with
some money sent along with it.

I don't know how I missed this, because I remember coming across this deficiency before.
I had missed a case, where silentsend is requested but with a message. Previously, it would
fail without any message to stdout or stderr (only a return code).
Now, silentsend with a message works even on pcoin.cpp (tcoin.cpp already had this change).

I made a mistake. I should have done this before making my commits.
That's the only reason why this merge is necessary.

I had forgotten to change \u23CE to <new-line> and introduce a check for <vertical-tab> in many many places
in tcoin.cpp and pcoin.cpp. I should probably put these things in some kind of function so I don't repeat myself.
I'll probably do that in a future commit.

constants
I had forgotten to handle the fatal errors and take the error numbers out into symbolic constants. I have now done that in tcoin.cpp and pcoin.cpp
|
| |
|
|
| |
This doesn't change functionality. It is simply a refactor that separates error codes out into symbolic constants in tcoin.cpp and pcoin.cpp.
|
| |
|
|
|
|
| |
<vertical-tab>
Newlines and vertical tabs in messages are replaced with <new-line> and <vertical-tab> to prevent transaction spoofing inside a message.

ntcoin's help said "tcoin subdirectories" for the first path argument. It was not clear whether this argument should include "/tcoin" or not. Now, this has been made clearer so that it means the 'tcoin' directory itself.
|
| |
|
|
| |
Fixed a typographical error in ntcoin (there was an extra ').
|
| |
|
|
| |
To ensure that builds are verifiable, tcoin_defs.cpp and pcoin_defs.cpp are copied from tcoin/bin to ~/bin (i.e., to the same directory as the 'tcoin' and 'pcoin' executables)

Just added a period/fullstop to the message in the show_balances() function.
