- tests that pass are most important because they show ljson accepts
everything that is valid json
- tests that fail because ljson follows the constraints set by json.org are
good because they show the limits of ljson's leniency
- tests that fail because ljson is too lenient are okay as long as they
don't cause a segfault or some other nasty behavior
We now rewrite the binary image at runtime on Windows and XNU to change
mov %fs:0,%reg instructions to use %gs instead. There's also simpler
threading API introduced by this change and it's called _spawn() and
_join(), which has replaced most clone() usage.
The patch in #469 was buggy for images where the start of a row matched
the end of the previous row. We don't re-issue the `setbgfg` ANSI codes
when we think that the color hasn't changed. But by sending an `\e[0m`
sequence at the end of the line without updating `bg` or `fg`, we
desynced `bg` and `fg` from the actual ANSI state. Now, we simply follow
that line-terminating `\e[0m` with another `setbgfg` call.
This bug was visible in images with a constant-color matte border:
![Screenshot of `printimage` output before and after this commit when
run on `lemurs.png` and `lemursborder.png`, where `lemursborder.png` has
a thick blue border around the outside of the image. Both versions look
fine for `lemurs.png`. For `lemursborder.png`, the "before" version has
a chess board pattern for the left border (except for the first row) and
the bottom border. The "after" version looks correct.][ss]

Our build was flaking due to ETXTBSY errors running multiple redbean
instances in parallel. This is due to the StoreAsset() support which
seems to cause enough problems it's worth making a *breaking change*
turning it off by default for now. There's a new -* flag, to restore
redbean's old self-modifying behavior.
- Fix DescribeSigset()
- Introduce new unix.rmrf() API
- Fix redbean sigaction() doc example code
- Fix unix.sigaction() w/ more than two args
- Improve redbean re module API (non-breaking)
- Enhance Lua with Python string multiplication
- Make third parameter of unix.socket() default to 0
It's never worked very well having nesemu1.com and printvideo.com
spawning an ffmpeg or sox subprocess and streaming audio samples via
pipes. Since these programs don't work very well for that purpose, and
if you're SSH'ing into the cloud, the speaker could be very far away.
This change is part of an experiment to instead patch desktop terminals
such as PuTTY, KiTTY, gnome-terminal, etc. to support receiving inband
audio samples as ANSI code, and then playing them on the speakers of the
local machine that's being used. This way we can use printf() as a cross
platform audio playback library.
This change fixes a regression from 281a0f27 which resulted in the
integer literal `0` being interpreted as a floating point number. This
should also fix a reported issue with Fennel integration.
The Compress() and Uncompress() APIs were a mistake. The functions
themselves work fine, but it's a design blemish and does superfluous
work. Since they were only introduced in the last few weeks, they're now
deprecated and references to them have been scrubbed from the website
and other documentation. Please use the new APIs since the old APIs will
be removed at some point in the future.
This change introduces automated Lua unit tests for the Redbean APIs.
There's a few functions that were broken which have now been fixed, e.g.
Underlong() and Decimate().
- Wrap clock_getres()
- Wrap sched_setscheduler()
- Make sleep() api conformant
- Polyfill sleep() using select()
- Improve clock_gettime() polyfill
- Make nanosleep() POSIX conformant
- Slightly improve some DNS functions
- Further strengthen pledge() sandboxing
- Improve rounding of timeval / timespec
- Allow layering of pledge() calls on Linux
- Polyfill sched_yield() using select() on XNU
- Delete more system constants we probably don't need
Rosetta doesn't correctly respect the startup registers as defined in LC_UNIXTHREAD
which makes platform detection go awry. But at least Rosetta appears to consistently
set rbx to 0x00000000ffffffff and rdx to 0x0000000000000001 at startup for every
x64 executable I could get my hands on. So we use that to detect Rosetta's presence
and set up the correct registers for XNU.
When a format string like %2x is provided, the width parameter was read
correctly as 2, but it was not used when decoding the number from the
input string (ie instead of reading 2 characters from the input string,
vcscanf read all the characters).
This change uses the value of width within the number decoding loop to
read fixed number of digits correctly. if width is zero (not provided),
the default of width is set as bits.
Fixes#423
