redbean lua handlers that perform sql queries can do 400k qps.
We now use a separate compile-time options for SQLite, when building the
SQLite shell versus building the production web serving code. It doesn't
seem appropriate for something like redbean to include backups, progress
callbacks, query completion, profiling, EXPLAIN, ALTER, ANALYZE, VACUUM,
etc. since those tasks are better left to the sqlite3.com shell program.
Lua SQLite pointer APIs have been removed since we're not using threads.
The Lua APIs for installing update / commit / rollback hooks are removed
due to a general sense of disagreement and an overall lack of comfort.
Full-Text Search and R*Tree are as large as the rest of SQLite combined.
Turning those off keeps redbean under 1mb when built for MODE=tiny which
is nice for marketing purposes.
If you need something that was removed, file an issue, and we'll add it.
Added necessary constants (DNS_TYPE_PTR, NI_NUMERICHOST etc.).
Implementation of getnameinfo is similar to getaddrinfo, with internal
functions:
* ResolveDnsReverse: performs rDNS query and parses the PTR record
* ResolveHostsReverse: reads /etc/hosts to map hostname to
address
Earlier, the HOSTS.txt would only need to be sorted at loading time,
because the only kind of lookup was name -> address. Now since address
-> name lookups are also possible, so the HostsTxt struct, the sorting
method (and the related tests) was changed to reflect this.
- Now integrated with `make tags` for Emacs IDE features
- Delete some old deprecated broken full-text search engines
- Rename .h → .inc files that don't meet our definition of header
- Make sure every #include line is normal form so tools understand
See #162
- Better UBSAN error messages
- POSIX Advisory Locks polyfills
- Move redbean manual to /.help.txt
- System call memory safety in ASAN mode
- Character classification now does UNICODE
This change brings page faults for precompressed static asset serving
down from 27 to 20 (or fewer) after fork. This is more of an art than
science. Hopefully Blinkenlights can visualize page faults soon.
This also fix a bug where CTRL-C'ing redbean on Linux would kill the
browser process. It furthermore fixes a regression with the APE self
repair process that happened in a recent change.
See #158
ASAN and vfork() don't appear to play well together. Maybe in later
versions of GCC it'll be better. But vfork() is flirting with danger
after all and that probably doesn't make sense in ASAN mode anyway.
A new -s flag has been added to increase silence. This change is
intended to make it a little less weird opening the redbean binary
directly from the browser and seeing an empty terminal window.
- Fix regression with `%lu`
- Added some more headers witnessed in the wild
- Added `-M INT` option to redbean to tune max payload size
- Work around InfoZIP 256 character limit on comment line size
If your redbean `/.init.lua` file defines a global callable named
`OnHttpRequest` then redbean will delegate all serving control to
your function. You may then restore the default serving paths, by
calling the new `Route()`, `RouteHost()`, and `RoutePath()` APIs.
Closes#150
redbean improvements:
- Explicitly disable corking
- Simulate Python regex API for Lua
- Send warmup requests in main process on startup
- Add Class-A granular IPv4 network classification
- Add /statusz page so you can monitor your redbean's health
- Fix regressions on OpenBSD/NetBSD caused by recent changes
- Plug Authorization header into Lua GetUser and GetPass APIs
- Recognize X-Forwarded-{For,Host} from local reverse proxies
- Add many additional functions to redbean Lua server page API
- Report resource usage of child processes on `/` listing page
- Introduce `-a` flag for logging child process resource usage
- Introduce `-t MILLIS` flag and `ProgramTimeout(ms)` init API
- Introduce `-H "Header: value"` flag and `ProgramHeader(k,v)` API
Cosmopolitan Libc improvements:
- Make strerror() simpler
- Make inet_pton() not depend on sscanf()
- Fix OpenExecutable() which broke .data section earlier
- Fix stdio in cases where it overflows kernel tty buffer
- Fix bugs in crash reporting w/o .com.dbg binary present
- Add polyfills for SO_LINGER, SO_RCVTIMEO, and SO_SNDTIMEO
- Polyfill TCP_CORK on BSD and XNU using TCP_NOPUSH magnums
New netcat clone in examples/nc.c:
While testing some of the failure conditions for redbean, I noticed that
BusyBox's `nc` command is pretty busted, if you use it as an interactive
tool, rather than having it be part of a pipeline. Unfortunately this'll
only work on UNIX since Windows doesn't let us poll on stdio and sockets
at the same time because I don't think they want tools like this running
on their platform. So if you want forbidden fruit, it's here so enjoy it
- POSIX regular expressions for Lua
- Improved protocol parsing and encoding
- Additional APIs for ZIP storage retrieval
- Fix st_mode issue on NT for regular files
- Generalized APIs for URL and Host handling
- Worked out the kinks in resource resolution
- Allow for custom error pages like /404.html
The most exciting improvement is dynamic pages will soon be able to use
the executable itself as an object store. it required a heroic technique
for overcoming ETXTBSY restrictions which lets us open the executable in
read/write mode, which means (1) wa can restore the APE header, and (2)
we can potentially containerize redbean extension code so that modules
you download for your redbean online will only impact your redbean.
Here's a list of breaking changes to redbean:
- Remove /tool/net/ prefix from magic ZIP paths
- GetHeader() now returns NIL if header is absent
Here's a list of fixes and enhancements to redbean:
- Support 64-bit ZIP archives
- Record User-Agent header in logs
- Add twelve error handlers to accept()
- Display octal st_mode on listing page
- Show ZIP file comments on listing page
- Restore APE MZ header on redbean startup
- Track request count on redbean index page
- Report server uptime on redbean index page
- Don't bind server socket using SO_REUSEPORT
- Fix#151 where Lua LoadAsset() could free twice
- Report rusage accounting when workers exit w/ -vv
- Use ZIP iattr field as text/plain vs. binary hint
- Add ParseUrl() API for parsing things like a.href
- Add ParseParams() API for parsing HTTP POST bodies
- Add IsAcceptablePath() API for checking dots, etc.
- Add IsValidHttpToken() API for validating sane ASCII
- Add IsAcceptableHostPort() for validating HOST[:PORT]
- Send 400 response to HTTP/1.1 requests without a Host
- Send 403 response if ZIP or file isn't other readable
- Add virtual hosting that tries prepending Host to path
- Route requests based on Host in Request-URI if present
- Host routing will attempt to remove or add the www. prefix
- Sign-extend UNIX timestamps and don't adjust FileTime zone
Here's some of the improvements made to Cosmopolitan Libc:
- Fix ape.S indentation
- Improve consts.sh magnums
- Write pretty good URL parser
- Improve rusage accounting apis
- Bring mremap() closer to working
- Added ZIP APIs which will change
- Check for overflow in reallocarray()
- Remove overly fancy linkage in strerror()
- Fix GDB attach on crash w/ OpenBSD msyscall()
- Make sigqueue() portable to most UNIX distros
- Make integer serialization macros more elegant
- Bring back 34x tprecode8to16() performance boost
- Make malloc() more resilient to absurdly large sizes
This isn't working as intended in the Travis CI build environment.
There's likely some kind of microarchitectural issue. This change
gets us back into the green for the time being.
Cosmopolitan's QuickJS is now equally conformant and performant, with
the exception of Atomics, which have been disabled since Cosmopolitan
currently doesn't support pthreads.
