el_runtime.c was deleted prematurely — elb still resolves the runtime at build time
via a hardcoded relative path, and the elc code generator still emits
#include "el_runtime.h" in generated C.
Restoring el_runtime.c + el_runtime.h as the working build runtime until the
compiler is updated to emit #include "el_seed.h" and link against el_seed.c
directly.
el_seed.h: remove #include "el_runtime.h" that broke after el_runtime.h deletion;
add inline el_val_t typedef + macros + float cast helpers so el_seed.h is fully
self-contained.
Add Server-Sent Events support to the El runtime. El v2 handlers can now
hold HTTP connections open and push events in real time.
New builtins in el_seed.c:
__http_conn_fd() — retrieve raw fd from thread-local set by worker
__http_sse_open(fd) — send SSE headers (text/event-stream), keep-alive
__http_sse_send(fd, data) — write "data: <data>\n\n" frame
__http_sse_close(fd) — close the connection fd
http_worker_v2 in legacy/el_runtime.c now:
- stashes the fd via el_seed_set_http_conn_fd() before calling the handler
- detects the "__sse__" sentinel return value to skip http_send_response
and skip close(fd) — SSE handler took ownership of the fd
- clears the thread-local after the handler returns
El wrappers added to runtime/http.el:
http_conn_fd() http_sse_open(fd) http_sse_send(fd, data)
http_sse_close(fd) http_sse_sentinel()
Introduces el_seed.c / el_seed.h as the clean OS-boundary layer for new-generation
El programs. All public symbols use the __ prefix convention; el_val_t (int64_t) is
the universal value type throughout.
Key additions over el_runtime.c:
- __thread_create / __thread_join: pthreads + dlsym(RTLD_DEFAULT) parallelism
foundation. Static ElThread table (64 slots); worker resolves El fn symbols at
runtime, stores result string for join to return.
- __mutex_new / __mutex_lock / __mutex_unlock: pooled pthread_mutex_t handles
- __http_do: unified curl call with JSON headers string (vs ElMap) and explicit
timeout_ms parameter
- __fs_list_raw: returns newline-separated filename string (not ElList)
- __str_char_at: returns Int byte value (not single-char String)
- __args_json: CLI args as JSON array string; seeded by el_seed_init_args()
JSON, state, engram, HTML/URL, serve — thin __ wrappers over el_runtime.c.
Private seed arena (parallel to el_runtime.c arena) for standalone use.
