This patch makes strto{u,}l{l,}() behave more to-spec about endptr.
"If endptr is not NULL, strtoull stores the address of the first invalid
character in *endptr."
This patch fixes an issue where the line editor would put no spacing
between suggestions (only when there are two suggestions).
To reproduce, try on a build with no ports (starting with `pro`):
```
> pro<tab>
profilepro
```
Many properties can now have percentage values that get resolved in
layout. The reference value (what is this a percentage *of*?) differs
per property, so I've added a helper where you provide a reference
value as an added parameter to the existing length_or_fallback().
This fixes the behavior for several inputs:
- '-0' (shouldn't work but was accepted)
- '+3' (shouldn't work but was accepted)
- '13835058055282163712' (should work but returned 9223372036854775807 with errno=ERANGE)
This strtod implementation is not perfectly accurate, as evidenced by the test
(accuracy_strtod.cpp), but it is sufficiently close (up to 8 eps).
The main sources of inaccuracy are:
- Highly repeated division/multiplication by 'base'
(Each operation brings a multiplicative error of 1+2^-53.)
- Loss during the initial conversion from long long to double (most prominently,
69294956446009195 should first be rounded to 69294956446009200 and then
converted to 69294956446009200.0 and then divided by ten, yielding
6929495644600920.0. Currently, it converts first to double, can't represent
69294956446009195.0, and instead represents 69294956446009190, which
eventually yields 6929495644600919.0. Close, but technically wrong.)
I believe that these issues can be fixed by rewriting the part at and after
double value = digits.number();
and that the loss before that is acceptable.
Specifically, losing the exact exponent on overflow is obviously fine.
The only other loss occurs when the significant digits overflow a 'long long'.
But these store 64(-7ish) bits, and the mantissa of a double only stores 52 bits.
With a bit more thinking, one could probably get the error down to 1 or 2 eps.
(But not better.)
Fixes#1979.
Currently we don't deal with them, so they shouldn't return a
SimpleSelector - that'd be a false positive.
Also don't produce a ComplexSelector if no SimpleSelector was parsed.
This fixes a couple of rendering issues on awesomekling.github.io:
link colours, footer size, content max-width (and possibly more!)
Previously we would only check if the border width property is empty and
skip drawing in that case, and enforcing a minimum width of 1px
otherwise - but "border: 0;" should not paint a border :^)
Back in 36ba0a35ee I thought that Travis would
automagically delete theoldest files. Apparently it does not.
Note that no dummy changes are needed, because BuildIt.sh lists itself
as a dependency for the Toolchain. Hooray for something that works!
This is very basic and doesn't support many features. Instead
of describing what it *doesn't* support, I'll describe what I
have tested:
1. Public key authentication (password is not supported)
2. Single command execution
3. PTY-less interactive bash shell (/bin/sh doesn't work)
4. Multi-user (i.e you can ssh as 'anon' as well as root)
We can now cycle pages of suggestions when there are more suggestions
than we can fit on one screen.
This does not inculude a visual indicator that more pages exist,
however.
We now look at the Content-Type HTTP header when deciding how to render
some loaded content. If there is no Content-Type header (which will
always be the case when loading local files, for example), we make a
guess based on the URL filename.
Previously we were wasting the bottom pixel row on darkness. Use the
base button color all the way to the bottom row and offset the top
highlight by one pixel instead.
