🔧 Core Refactoring (backend)
• All shared logic from the webroot shell scripts (compile.sh, clean.sh, profile.sh, update.sh) has been extracted into a new common file webroot/lib.sh: logging, localization (t()), parsing of numeric values, sorting packages by size, splitting into workers, profile compilation/reset, and writing statistics. Code duplication between the scripts has been eliminated.
• The standalone binary system/bin/deop (run via su -c deop) was rewritten in the same style, but it does not source the shared lib.sh — some of the logic (parsing, process splitting, compilation) is duplicated inside it rather than reused.
• The number of parallel processes is now clamped to the range 1–25 via clamp_parts() (in v8 the CLI menu limited it to 1–10, while the web compilation scripts had no limit at all).
• Added a reusable has_internet() function for connection checks instead of inline ping calls scattered in different places.
🐛 Fixes in update.sh
• Previously UPDATE_URL was requested twice (once for version, once for zipUrl) — now a single JSON response is reused for both fields.
• Previously the $ZIP_FILE was created empty before the download, so the check [ -f "$ZIP_FILE" ] could succeed even if the download completely failed. Now the file is deleted beforehand, and after the download the check is [ -s "$ZIP_FILE" ] (not just existence, but non-zero size) — this also catches interrupted downloads that leave a 0-byte file.
• Explicit internet check (has_internet) added at the beginning with a localized error message.
• Early check added to ensure the JSON was actually received (wget did not return empty content).
🌐 Webroot backend (oresty.conf)
• New endpoint /dex_optimizer/stats — calculates statistics on the server side (Lua) and returns ready-made JSON: number of optimized apps, number of runs, speed gain (speedGain, % relative to previous compilation runs), percentage of successful dex compilations (dexPct), and an array of points for the chart (up to the last 30 compilation runs).
• New endpoint /dex_optimizer/last_run_time — returns the timestamp of the last run from stats.txt.
• New endpoint /dex_optimizer/update — starts update.sh via a POST request directly from the web interface (previously updates could only be started manually or on a schedule).
• Handling of a missing log file fixed: previously an io.open error “No such file” returned 500; now it correctly returns 204 No Content.
🎨 Web interface (webroot)
• Removed dependencies on Chart.js, chartjs-adapter-date-fns, chartjs-plugin-zoom, and Hammer.js (4 files). The statistics chart is now drawn by a lightweight custom function drawChart() — simple bar chart without third-party libraries, which noticeably reduces the size of the webroot.
• index.html, script.js, and styles.css have been substantially rewritten (hundreds of changed lines) to support the new chart logic, server-side statistics endpoints, and UI/theme refinements.
• The module update button/logic now calls the new /dex_optimizer/update endpoint instead of the previous method.
📦 Other
• webroot/oresty.conf: unnecessary indentation removed from the root location block for .sh scripts (cosmetic change, does not affect behaviour).
