* **Performance** * Improved memory usage and persistence speed for large playlists and electronic programme guides. * Large EPG datasets now process more reliably while preserving channel priorities and cleaning up temporary data. * Reduced allocation overhead during parsing and playlist processing. * **Bug Fixes** * Prevented programme descriptions from being truncated during XMLTV imports. * Improved handling of empty or single-source EPG data. * **Network** * Optimized response compression by avoiding compression for small or already-compressed media files.

Usage: bin/profile.sh [debug|release] [settings_dir] [output_dir]
|
|
|
|
Arguments:
|
|
debug|release Build/profile mode. Default: release
|
|
settings_dir Path passed to tuliprox via -H. Required.
|
|
output_dir Where to write the heaptrack artefact. Default: /tmp
|
|
|
|
Produces in output_dir:
|
|
tuliprox-<mode>.heaptrack.zst Heap allocations (only)
|
|
|
|
NOTE on CPU profiling: this script no longer wraps samply. Samply 0.13.1 in
|
|
this environment writes profile metadata but no `samples` payload, while
|
|
`perf record` captures ~19k samples on the same workload — so for CPU
|
|
profiles use `perf record -F 999 -o out.perf -- <cmd>` directly and convert
|
|
with `samply convert` if you want a Firefox Profiler view.
|
|
|
|
Environment:
|
|
PROFILE_TARGET Target name passed via `-t`. If unset, tuliprox runs in
|
|
server mode after the update and the script will hang
|
|
waiting for it to exit. REQUIRED for headless runs.
|
|
RELEASE_DEBUG_INFO If 1, release builds keep debug info. Default: 1
|
|
RELEASE_NO_LTO If 1, disable LTO for release builds. Default: 1
|
|
(LTO inflates release build time ~10x without helping
|
|
the sample, and the slow link step eats into CI minutes)
