Decimal 0.5.1+ changed to banker's rounding (round to nearest even
number), and math-functions 0.3.3.0 (used by roi) fixed various
precision-related issues. Now we require the latest versions of these.
This was causing some functional test failures when building with old
GHCs/snapshots.
This commit introduces IPv6 support (and thus closes#1145).
It also allows using local hostnames as a parameter for --host.
For this, multiple things needed to be changed:
- checkWebOpts is dropped, as the supplied parameter is checked later
by Network.Socket.getAddrInfo
- defbaseurl needs to check if : is used in the host, as this indicates
the usage of an IPv6 address. In this case, the host needs to be
wrapped in [] for the base URL
- To allow opening such a modified base URL, runHostPortFullUrl is used
instead of runhostPortUrl, as it allows opening arbitrary URLs instead
of a path prefixed with http://127.0.0.1
As checking the host for validity is postponed until the webserver tries
to start, an invalid hostname leads to an exception caused by
Network.Socket.getAddrInfo.
This is still fine, as hledger-web won't start in an undefined state, but
will terminate with a nonzero exit code.
This commit adds the --socket option to use hledger-web over an AF_UNIX socket
file.
It allows running multiple instances of hledger-web on the same system without
having to manually choose a port for each instance, which is helpful for running
individual instances for multiple users. In this scenario, the socket path is
predictable, as it can be derived from the username.
It also introduces the following dependencies:
- network
- Used to create the unix domain socket
- unix-compat
- Used to identify if the socket file is still a socket, to reduce the risk
of deleting a file when cleaning up the socket
- Modified the cors option to require a String
- Moved the logic to build the cors policy to WebOptions.hs
- Specify the --cors "*" example in the cors option help
- Added utf8-string dependency to convert a String into a ByteString
in JournalReader.hs. If you still need this, feel free to work on
those errors. But hopefully not, because dropping base 4.8 should
permit some code cleanups.
