fix: fixes FATAL SIGNAL 11 on gossmap node
a104380
This will fix a crash that I caused on armv7
and by looking inside the coredump with gdb
(by adding an assert on n that must be
different from null) I get the following stacktrace
```

db: avoid calling memcpy on NULL
45cb2b1
It is possible for db_column_bytes() to return 0 and for
db_column_blob() to return NULL even when db_column_is_null() returns
false. We need to short circuit in this case.

plugins: fix %*.s typo.
8f6d3d8
And add a check for new uses creeping in, since it got cut & paste
everywhere.
This means "this is a valid string, but truncate it to this many characters"
vs "%.*s" which means "only read this many characters of string":

fix: fixes FATAL SIGNAL 11 on gossmap node
a104380
This will fix a crash that I caused on armv7
and by looking inside the coredump with gdb
(by adding an assert on n that must be
different from null) I get the following stacktrace

I do not know if this is a solution because I do not know
when I can parse a node announcement for a node that
it is not longer in the gossip map.
So, I hope this is just usefult for @rustyrussell

fix: fixes FATAL SIGNAL 11 on gossmap node
a104380
This will fix a crash that I caused on armv7
and by looking inside the coredump with gdb
(by adding an assert on n that must be
different from null) I get the following stacktrace

I do not know if this is a solution because I do not know
when I can parse a node announcement for a node that
it is not longer in the gossip map.
So, I hope this is just usefult for @rustyrussell

db: avoid calling memcpy on NULL
45cb2b1
It is possible for db_column_bytes() to return 0 and for
db_column_blob() to return NULL even when db_column_is_null() returns
false. We need to short circuit in this case.

plugins: fix %*.s typo.
8f6d3d8
And add a check for new uses creeping in, since it got cut & paste
everywhere.
This means "this is a valid string, but truncate it to this many characters"
vs "%.*s" which means "only read this many characters of string":

fix: fixes FATAL SIGNAL 11 on gossmap node
a104380
This will fix a crash that I caused on armv7
and by looking inside the coredump with gdb
(by adding an assert on n that must be
different from null) I get the following stacktrace
```

I do not know if this is a solution because I do not know
when I can parse a node announcement for a node that
it is not longer in the gossip map.
So, I hope this is just usefult for @rustyrussell

db: avoid calling memcpy on NULL
45cb2b1
It is possible for db_column_bytes() to return 0 and for
db_column_blob() to return NULL even when db_column_is_null() returns
false. We need to short circuit in this case.

plugins: fix %*.s typo.
8f6d3d8
And add a check for new uses creeping in, since it got cut & paste
everywhere.
This means "this is a valid string, but truncate it to this many characters"
vs "%.*s" which means "only read this many characters of string":

fix: fixes FATAL SIGNAL 11 on gossmap node
a104380
This will fix a crash that I caused on armv7
and by looking inside the coredump with gdb
(by adding an assert on n that must be
different from null) I get the following stacktrace
```

db: avoid calling memcpy on NULL
45cb2b1
It is possible for db_column_bytes() to return 0 and for
db_column_blob() to return NULL even when db_column_is_null() returns
false. We need to short circuit in this case.

plugins: fix %*.s typo.
8f6d3d8
And add a check for new uses creeping in, since it got cut & paste
everywhere.
This means "this is a valid string, but truncate it to this many characters"
vs "%.*s" which means "only read this many characters of string":

db: avoid calling memcpy on NULL
45cb2b1
It is possible for db_column_bytes() to return 0 and for
db_column_blob() to return NULL even when db_column_is_null() returns
false. We need to short circuit in this case.

plugins: fix %*.s typo.
8f6d3d8
And add a check for new uses creeping in, since it got cut & paste
everywhere.
This means "this is a valid string, but truncate it to this many characters"
vs "%.*s" which means "only read this many characters of string":

fix: fixes FATAL SIGNAL 11 on gossmap node
a104380
This will fix a crash that I caused on armv7
and by looking inside the coredump with gdb
(by adding an assert on n that must be
different from null) I get the following stacktrace

I do not know if this is a solution because I do not know
when I can parse a node announcement for a node that
it is not longer in the gossip map.
So, I hope this is just usefult for @rustyrussell
