replaceCalls() ended with strlen(&buffer[pos]), so the length recorded for a
file was the distance to its first 0x00 byte rather than the file size. The
byte just past the content happens to be zero today, which is the only reason
the numbers come out right.
Nothing in html/ contains a 0x00 today, so this is latent, but it is a trap
waiting for the first gzipped or binary asset: gzip puts a zero in the fourth
byte of its header. A gzipped style.css lands in the index as 3 bytes, and
since addr advances by that same value the next file is placed 3 bytes in and
overwrites what came before it. Two gzipped files in html/ are enough to see
it: both come out as 3 bytes and the second sits 1356 bytes inside the first.
Pass the length in and return the adjusted one. The substitution shortens
#{function} to #{NNN}, so the delta is known without measuring. The loops are
bounded by the length as well, which also covers -n, where nothing had put a
terminator in the buffer for strlen to find in the first place.
No output change: the image built from an unmodified html/ is byte for byte
the same before and after, and html_data.h is identical.
index.html now contains all pages as sections (overview, ports, stat,
vlan, l2, mirror, lag, eee, bandwidth, system, update); the sidebar
switches between them via the URL hash (#/ports, #/vlan, ...).
login.html stays separate as the authentication gate.
A section's initialisation runs when the section is shown, its polling
intervals run only while it is visible, and re-entering a section
refetches the data; the checkbox builders (lag/vlan/mirror) and the L2
scanner were made idempotent so re-initialising cannot duplicate rows.
tools/minify.py: recognise regex literals - an escaped slash before the
closing delimiter was previously stripped as a // comment.
Measured (make MACHINE=KP_9000_6XHML_X2): 8 embedded files, 109,814 ->
97,730 -> 25,302 bytes gzip (23.0 %); the data block ends at 0x462d6
(~86 KB freed). On a real PCB-K0402WS-V3: cold load ~450 ms, section
switches ~60-160 ms with no asset re-downloads, all sections render
without JavaScript errors.
All 17 page scripts (i18n, shared helpers, navigation and the per-page
scripts) are merged into one html/main.js that every page loads as its
only script, so the browser fetches it once and gzip can compress
across all of it.
The page-specific initialisation is guarded by the presence of the
matching page elements (it used to be selected implicitly by which
script a page loaded); the sidebar fill and the stat popup wiring moved
into DOMContentLoaded handlers because the bundle loads in <head>,
before the body exists.
tools/httpd_sim.h: BUFFER_SIZE 24000 -> 131072 so the simulator can
serve the larger bundle (the firmware is unaffected, it serves the
gzip'd bundle of ~17 KB).
Measured (make MACHINE=KP_9000_6XHML_X2): the JS drops from 23,302 to
16,948 bytes gzip; the whole Web UI from 34,784 to 28,200 bytes (25.3 %
of the raw 111,280); the data block ends at 0x46e28. Verified with a
headless browser against httpd_sim and against a real PCB-K0402WS-V3:
all pages render, the sidebar and the port strip are drawn, no
JavaScript errors.
Two build-time steps shrink the embedded Web UI (html/) from 113,015 to
34,784 bytes (30.8 %):
- tools/minify.py (new): string-literal-safe minifier that strips
comments and indentation; comments are pure overhead on the wire, so
the transfer size drops already before gzip (113,015 -> 101,498).
Binary files (.ico) are copied through unchanged. The output goes to
output/html_min/, the new fileadder input.
- fileadder -z: gzip-compresses every added file (zlib gzip format,
Z_BEST_COMPRESSION); the generated f_data entries carry a gzip flag.
tools/Makefile links the tool against -lz.
- httpd: adds "Content-Encoding: gzip" for flagged entries; the 8051
only copies compressed bytes, decompression happens in the browser.
The JSON API stays uncompressed.
Fixes required to make the sizes deterministic:
- fileadder terminated files at data_read + 1, so the strlen()-based
size computation depended on uninitialised buffer content; the NUL
now lands directly after the content.
- version.h was .PHONY, so every build rewrote it while parallel builds
could read a half-written copy.
- the file list was unscoped and missed .css/.ico; it is now scoped to
html/ and covers all embedded types.
Measured with make MACHINE=KP_9000_6XHML_X2: data block end moves from
0x5b977 to 0x487e0 (~78 KB freed on a 512 KB image). Verified with
MACHINE=PCB_K0402WS_V3 and on real hardware (PCB-K0402WS-V3).
Add a language selector to the System Settings page supporting English,
Japanese, and Chinese. The i18n dictionary already contained zh
translations but lacked the UI to switch languages.
Changes:
- html/i18n.js: add sys_language key to en/ja/zh
- html/system.html: add language selector dropdown
- html/system.js: add changeLang() and selector initialization
- tools/httpd_sim.c: fix cookie parsing for multi-cookie headers;
fix Set-Cookie response (missing Path=/, missing \r\n\r\n);
add SO_REUSEADDR for faster port reuse
The presence of the main function is a hardcoded trigger in sdcc that causes
the interrupt vectors and atomic rollback helpers to be generated as part of
compilation of the file containing the main function.
This makes sure the runtime library is correctly initialized and reduces
crtstart.asm to contain only the banked call helpers.
To ensure that the __interrupt_vect in area HOME is located at the beginning
of the firmware, the linker flags are updated to set the HOME start to
0x00000 and the linker object order is modified to have rtlplayground.rel
first.

The Makefile has the version number and generates a version.h which
has VERSION_SW define that looks like "v<VERSION>-g<GIT_SHORT_HASH>".
Software version shows at boot in the serial console.
And shown with command: `version`.
It can also be requested via `information.json`.

flash_read_bulk() is kind of a printf function. But did not work as well.
flash_read_bulk() was used in the http generation so this needed to be changed as well.
For the website we decided that we are going to use CSR(Client Side Rendering).
So every HTML and JS files are now static.
Variables are fetched via json calls and output is render on the client side.
Also usefull for the future when we want a REST like API.
execute_config() was also using flash_read_bulk().
This have been replaced with flash_read_bulk() and parsing the flash_buf buffer.
