The llama-cpp-localai-paged backend reused backend/cpp/llama-cpp's LLAMA_VERSION, which .github/workflows/bump_deps.yaml auto-bumps nightly to the latest ggml-org/llama.cpp master tip. The stock backend is patch-free so that bump is safe, but the paged backend applies a vendored patch series (backend/cpp/llama-cpp/patches/paged/) hand-verified bit-exact against ONE specific tip. A naive bump moves the tip out from under the patches and breaks 'git apply' at build time - a dep-bump PR would go red (or, worse, the break surfaces later in a release build). Mirror the turboquant precedent: give the paged wrapper its OWN LLAMA_VERSION pin (the verified 9d5d882d) and force it into every copied build via LLAMA_VERSION=$(LLAMA_VERSION), so the nightly stock bump no longer drags the paged build to an unverified tip. Unlike turboquant (whose fork branch carries the patches and is safe to auto-bump), the paged series is vendored, so it gets NO bump_deps.yaml entry: it is advanced only by the manual PIN_SYNC process. Add cross-referencing comments in both Makefiles and bump_deps.yaml. Also add PIN_BUMP_APPLY_CHECK.md: an apply-feasibility report for the latest tip (c299a92c, 23 commits ahead). The full series applies CLEAN under 'git apply' with only benign line offsets and zero conflicts; the lone failure (0019) is a pre-existing stray dev-doc hunk, identical on the current pin, not a bump regression.

# llama-cpp-localai-paged is LocalAI's paged-attention llama.cpp variant. It
|
|
# builds upstream llama.cpp with the LocalAI paged-attention patch series
|
|
# (backend/cpp/llama-cpp/patches/paged/) applied on top (LLAMA_PAGED=on). It
|
|
# reuses backend/cpp/llama-cpp's grpc-server.cpp / CMakeLists.txt / prepare.sh
|
|
# sources verbatim via a thin wrapper.
|
|
#
|
|
# Pin handling (mirrors the turboquant wrapper, the precedent this is modelled
|
|
# on): the paged patch series is hand-verified bit-exact against ONE specific
|
|
# llama.cpp tip and re-exported by the manual PIN_SYNC process
|
|
# (backend/cpp/llama-cpp/patches/paged/PIN_SYNC_*.md). A naive pin bump would
|
|
# move the tip out from under the patches and break `git apply` at build time,
|
|
# so this backend OWNS its pin (LLAMA_VERSION below) instead of inheriting the
|
|
# auto-bumped stock pin from backend/cpp/llama-cpp/Makefile. The override is
|
|
# forced into every copied build via `LLAMA_VERSION=$(LLAMA_VERSION)`. There is
|
|
# deliberately NO bump_deps.yaml entry for it: it is advanced ONLY by PIN_SYNC,
|
|
# never nightly. (turboquant CAN auto-bump because its fork branch carries the
|
|
# patches; the paged series is vendored as .patch files here, so it cannot.)
|
|
#
|
|
# - NO patch-grpc-server.sh and NO apply-patches.sh: the shared
|
|
# grpc-server.cpp already carries the (runtime-gated) paged option hooks,
|
|
# and the paged patch series is applied by the copied llama-cpp Makefile's
|
|
# own `llama.cpp` target whenever LLAMA_PAGED=on (which we force below).
|
|
|
|
# Manually pin-synced llama.cpp tip the paged patch series is verified against.
|
|
# Decoupled from the auto-bumped stock pin in backend/cpp/llama-cpp/Makefile so
|
|
# the nightly llama.cpp bump cannot silently break the vendored paged patches.
|
|
# Advance ONLY via the PIN_SYNC process (rebase patches + bit-exact gate +
|
|
# re-export), then update this value. See:
