doc/manpages: regenerate manpages using markdown templates
5 years ago
.TH "LIGHTNING-WAITINVOICE" "7" "" "" "lightning-waitinvoice"
.SH NAME
docs: Update manpages to be recognized correctly by mrkd mrkd started enforcing the `name -- short description` style of top-level headings somewhere, and was thus failing to build the man-pages. I swapped the title and with the existing short description to make it work again. `mrkd` will automatically infer the section from the filename so no need to put it in the title as well. In addition I removed the "last updated" lines at the bottom since they are out of date at best, and misleading at the worst. If we want to keep them, I'd suggest generating them from the commit that last touched them.

lightning-waitinvoice - Command for waiting for specific payment
doc/manpages: regenerate manpages using markdown templates
5 years ago
.SH SYNOPSIS
doc: add lightning-waitinvoice man page. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

\fBwaitinvoice\fR \fIlabel\fR
doc/manpages: regenerate manpages using markdown templates

.SH DESCRIPTION
The \fBwaitinvoice\fR RPC command waits until a specific invoice is paid,
then returns that single entry as per \fBlistinvoice\fR\.
.SH RETURN VALUE
On success, an invoice description will be returned as per
\fBlightning-listinvoice\fR(7)\. The \fIstatus\fR field will be \fIpaid\fR\.
Use dedicated type for error codes Before this patch we used `int` for error codes. The problem with `int` is that we try to pass it to/from wire and the size of `int` is not defined by the standard. So a sender with 4-byte `int` would write 4 bytes to the wire and a receiver with 2-byte `int` (for example) would read just 2 bytes from the wire. To resolve this: * Introduce an error code type with a known size: `typedef s32 errcode_t`. * Change all error code macros to constants of type `errcode_t`. Constants also play better with gdb - it would visualize the name of the constant instead of the numeric value. * Change all functions that take error codes to take the new type `errcode_t` instead of `int`. * Introduce towire / fromwire functions to send / receive the newly added type `errcode_t` and use it instead of `towire_int()`. In addition: * Remove the now unneeded `towire_int()`. * Replace a hardcoded error code `-2` with a new constant `INVOICE_EXPIRED_DURING_WAIT` (903). Changelog-Changed: The waitinvoice command would now return error code 903 to designate that the invoice expired during wait, instead of the previous -2

On error the returned object will contain \fBcode\fR and \fBmessage\fR properties,
with \fBcode\fR being one of the following:
.RS
.IP \[bu]
-32602: If the given parameters are wrong\.
.IP \[bu]
-1: If the invoice is deleted while unpaid, or the invoice does not exist\.
.IP \[bu]
903: If the invoice expires before being paid, or is already expired\.

doc, wiregen: use SHA256 stamps instead of git versions. This should be more robust in future: we SHA256 all of the deps. For wiregen we prefix with EXPERIMENTAL_FEATURES, since it can effect them. Signed-off-by: Rusty Russell &lt;rusty@rustcorp.com.au&gt;
