Merge Risk: 🟠 High · up to The SQLite migration still has unresolved correctness and availability risks: multi-token searches can match unintended fields, and a damaged nightly index can make all searches fail instead of falling back safely. Edge-case input and capacity handling also need fixes, so the PR is not merge-ready without addressing these issues or explicitly accepting the risk. 🚥 Pre-merge checks | ✅ 4✅ Passed checks (4 passed)

search_indom_tableorders rows withORDER BY type, which is ascending:SEARCH_DOC_METRIC(1), thenSEARCH_DOC_INDOM(2), thenSEARCH_DOC_INST(3). The same function assigns scores whereSEARCH_DOC_INDOMis highest at 2.0,SEARCH_DOC_METRICis 1.0 and the rest 0.5.Results are therefore delivered in ascending type order while the reported score implies descending relevance with the indom first.

- Around line 1999-2013: Update the SQLite detection block around
PKG_CHECK_MODULES and the sqlite3 AC_CHECK_LIB fallback to enforce SQLite >=
3.9.0 rather than checking only sqlite3_open. Add a compile-time capability
probe against the selected SQLite library that creates an FTS5 virtual table,
and set HAVE_SQLITE3/lib_for_sqlite3 to unavailable when either the version or
FTS5 check fails.
In `@src/libpcp_web/src/search.c`:
- Around line 711-714: The disabled-search branch in pmSearchSetup currently
returns before module->on_setup, leaving pmsearch without a diagnostic because
it ignores the setup result. Update the pmSearchSetup/module->on_setup flow or
the pmsearch caller to propagate and handle the disabled state, ensuring
pmsearch reports that search is disabled instead of silently exiting.
- Around line 168-176: Update the SQL construction in search_do_text_query to
add bound LIMIT and OFFSET parameters using request->count and request->offset,
so SQLite materializes only the requested result window. Adjust parameter
binding accordingly, and preserve accurate hits[i].total by obtaining the full
match count separately with a COUNT(*) query; otherwise explicitly change the
reported total semantics to indicate it is capped.
- Around line 292-293: Capture the return value from search_query_table and
propagate any -EIO or -ENOMEM failure to on_done instead of always reporting
zero hits; preserve the existing success result handling. Apply the same error
propagation pattern in search_do_text_suggest and search_do_text_indom, ensuring
their on_done calls receive the query error status.
- Around line 61-65: Update the FTS5 MATCH construction and execution flow
around the request query so malformed expressions retry once using the query as
a quoted phrase, as documented. Preserve column-filter handling, and ensure the
fallback applies when preparation or execution reports an FTS5 syntax error
rather than silently returning zero results.
- Around line 192-207: The hit-array growth logic performs overflow-prone
doubling and is duplicated across three search functions. In
src/libpcp_web/src/search.c lines 192-207, 355-370, and 475-490, extract the
shared logic into a helper such as search_hits_grow, validate the maximum before
doubling, and cast the resulting capacity to size_t for realloc; replace each
duplicated block with the helper call and let callers handle sqlite3_finalize on
failure.
- Around line 189-190: Propagate SQLite read failures through search.c: in
search_query_table (lines 189-190), search_suggest_table (line 352), and
search_indom_table (line 472), check each loop’s final rc and return -EIO unless
it is SQLITE_DONE; in search_do_text_suggest (line 419) and search_do_text_indom
(lines 536-538), capture the helper return value and pass negative failures to
on_done instead of always reporting success. Apply these changes at all listed
sites in src/libpcp_web/src/search.c.
- Around line 335-339: Update the SQL construction in the search query path to
use SEARCH_DOC_METRIC and SEARCH_DOC_INST instead of hardcoded type values,
keeping the existing filter semantics. Replace the sdscatfmt call with the
direct SDS string-construction function intended for format-free strings, such
as sdsnew.
- Around line 594-611: Move creation of the docs_vocab FTS5 vocabulary table
from the read-only pmSearchInfo path into the index-building flow in
search_sqlite.c, ensuring it is created alongside the docs index before readers
open the database. Remove the reader-side DDL dependency while preserving
pmSearchInfo’s query of the prebuilt docs_vocab table so terms and records are
populated on read-only connections.
- Around line 724-763: Update the index-open failure handling in the
pmSearchSetup flow to call pmNotifyErr at warning level whenever an explicitly
configured index cannot be opened or both nightly and base indexes fail, without
gating that report on pmDebugOptions.search. Preserve the existing fallback
behavior and debug diagnostics, and include the relevant path or failure context
in the warning.
- Around line 23-25: Replace the duplicate SEARCH_DOC_METRIC, SEARCH_DOC_INDOM,
and SEARCH_DOC_INST definitions with the corresponding PM_SEARCH_TYPE_METRIC,
PM_SEARCH_TYPE_INDOM, and PM_SEARCH_TYPE_INST values, or use those enum
constants directly throughout the newhelp writer and web search reader. Preserve
the raw SQLite type values so stored documents and filtering remain aligned with
pmSearchTextType.
- Around line 456-459: Update the query construction around the docs lookup so
indom filtering uses an indexed ordinary-table path instead of applying equality
directly to the FTS5 docs table’s UNINDEXED indom column. Add or reuse a
B-tree-backed indom mapping indexed by indom, join it to docs by rowid, and
preserve the selected columns and ORDER BY type behavior.
In `@src/newhelp/GNUmakefile`:
- Around line 21-23: Update the GNUmakefile build inputs around CFILES and
LCFLAGS so search_sqlite.c is compiled only when HAVE_SQLITE3 is enabled, and
apply SQLITE3CFLAGS and LIB_FOR_SQLITE3 under the same condition. Otherwise,
make the configured build fail when SQLite support is unavailable rather than
compiling search_sqlite.c without its headers and libraries.
In `@src/newhelp/newhelp.c`:
- Around line 473-491: Update the initialization block guarded by pmns_loaded to
check the return values of pmLoadASCIINameSpace and pmNewContext, report any
failure once, and mark pmns_loaded as initialized even when setup fails so
subsequent metric lookups do not retry or block. Preserve the existing lookup
behavior when both calls succeed, while leaving indom_buf empty after
initialization failure.
In `@src/pmdas/GNUmakefile`:
- Around line 97-108: Update the HAVE_SQLITE3 recipe in the GNUmakefile to skip
the pcp.search index generation and installation when CROSS_COMPILING is yes,
matching the existing guard used by the newhelp build. Within the
non-cross-compiling path, make failure of $(TOPDIR)/src/newhelp/newhelp -S stop
the recipe before installing or removing the generated index, while preserving
the existing help-file discovery and installation behavior.
In `@src/pmsearch/pmsearch_index.sh`:
- Around line 197-234: Update the index-generation flow around BASE, newhelp,
and the failure cleanup to build in a temporary file in the same directory as
INDEX, copy BASE into that file, and pass it to newhelp via its output option.
Rename the completed temporary file to INDEX only after newhelp succeeds; ensure
the temporary file is removed on failure, on the no-runtime-data exit path, and
by the existing exit trap.
- Around line 77-87: Update the metric-to-indom mapping command in the pminfo
mapping block to use the `-d` option instead of `-I`, while preserving the
existing awk extraction of `InDom:` values and output to `metric_indom`.
In `@src/pmsearch/pmsearch_index.timer`:
- Around line 14-16: In the [Install] section of pmsearch_index.timer, replace
RequiredBy=pmproxy.service with WantedBy=pmproxy.service while preserving the
existing timers.target relationship, so the optional timer does not create a
hard dependency on pmproxy.service.
In `@src/pmsearch/pmsearch.c`:
- Around line 394-403: Update on_search_done() to record a failed sts in the
daemon status so query, suggest, indom, and info failures propagate to the
process exit code. In the flow around pmSearchSetup() and pmSearchClose(), also
check pmSearchSetup()’s return value and use its failure code when setup fails
before closing and returning the final status.
---
Outside diff comments:
In `@man/man3/pmsearchsetup.3`:
- Around line 115-119: Update the pmSearchDoneCallBack documentation to describe
on_done as a synchronous completion callback invoked before the successful API
call returns. Replace the “asynchronous interfaces” wording and state that it
signals successful completion of the call while preserving the status-code
description.
---
Minor comments:
In `@qa/1687`:
- Around line 18-21: Add a shared SQLite FTS5/index-writing capability probe,
preferably in qa/common.check or qa/common.filter, and invoke it after the
existing tool checks in qa/1687 lines 18-21, qa/1871 lines 18-23, and qa/1872
lines 17-22; each test must call _notrun when indexing is unavailable, with
qa/1872 performing this before the pmproxy and curl checks.
In `@qa/1871`:
- Around line 34-39: The _filter_info helpers mask counter values, so add
independent positive-value assertions while preserving the existing filters: in
qa/1871 lines 34-39, validate that each docs, terms, and records counter from
pmsearch -C -i is greater than zero; in qa/1872 lines 50-57, validate that the
JSON docs, terms, and records values from /search/info are greater than zero.
In `@src/libpcp_web/src/search.c`:
- Around line 536-553: Update the result-delivery path in search_do_text_query
to order hits by descending score before the callbacks->on_text_result loop,
matching the scores assigned by search_indom_table; alternatively, change
search_indom_table’s query ordering to produce that same descending relevance
order. Preserve offset, count, total, and timer handling after sorting.
- Around line 579-582: Update the index-state checks in pmSearchInfo,
pmSearchTextQuery, pmSearchTextSuggest, and pmSearchTextInDom so a NULL or
unloaded smd consistently completes with -ENOENT. Keep -EINVAL for missing,
invalid, or otherwise malformed request/query inputs, preserving the distinction
between unavailable indexes and bad requests.
- Line 801: Update search.c to include slots.h and remove the local extern
declarations of keys_slots_end_phase, including the related declarations around
lines 820-824, so the function signature is sourced from the shared header.
- Around line 303-313: Prevent unsigned overflow in the result-loop bounds in
both the shown search path and search_do_text_indom: replace the offset + count
comparison with an overflow-safe end-index check or clamp the request values
before iterating. Preserve normal pagination behavior while ensuring large
offset/count inputs still deliver valid results instead of silently producing
none.
- Around line 826-833: Document in the pmsearch.1 and pmsearch_index.1 manual
pages that newly loaded or discovered metrics and instances are not searchable
until the scheduled index rebuild (or the next pmsearch_index run). Remove the
unnecessary keys_search_text_add call from schema loading in schema.c while the
function remains a no-op, and leave the discovery no-op behavior unchanged.
- Around line 256-264: Update score_cmp to apply a deterministic secondary
comparison when scores are equal, ordering first by the stable name field and
then by docid if names also match. Preserve the existing descending score order
and return zero only when all compared tie-breaker fields are equal.
- Around line 716-718: Replace the unchecked atoi parsing of "result.count" in
both the shown initialization path and keysSearchInit with validated strtoul
parsing. Accept only fully numeric, in-range values greater than zero; reject
malformed, zero, or out-of-range input and preserve the existing default
smd->resultcount.
In `@src/newhelp/newhelp.c`:
- Around line 241-255: Update the sscanf call in the PCP_VAR_DIR parsing block
to bound the %s conversion to var_dir’s capacity, using MAXPATHLEN - 1 or an
equivalent sizeof(var_dir)-based format. Preserve the existing parsing and break
behavior.
In `@src/pmsearch/pmsearch_index.timer`:
- Line 3: Add an explicit comment adjacent to the PartOf=pmcd.service setting in
pmsearch_index.timer explaining that restarting pmcd must also restart the
rebuild timer, which is required by pmproxy.service while pmsearch_index.service
uses Restart=no. Keep the existing service dependency configuration unchanged.
---
Nitpick comments:
In `@qa/group`:
- Line 2243: Add the `help` group to both new test entries for `newhelp -S` in
`qa/group`, preserving their existing numeric ordering and group assignments so
`check -g help` includes these index-writing tests.
In `@src/libpcp_web/src/search.c`:
- Line 17: Remove the unused <assert.h> include from search.c, leaving the
remaining includes and implementation unchanged.
- Around line 787-796: Update the module cleanup function around
searchModuleData so it no longer clears the process-wide search_enabled state;
rely on the per-module smd->loaded state for enabled-status reporting, and
remove the redundant memset before free while preserving database closure and
privdata cleanup.
- Around line 400-417: The anonymous prefix-expression block in the search
request path should become a named helper, such as the existing search
match-building helpers, with a unit-testable interface. Move the dotted-token
construction into that helper, track whether a token was appended with an
explicit first-token flag instead of checking start > 0, and preserve the output
for normal metric names without leading spaces. Ensure separator-only queries do
not produce the invalid name : (*) expression; return an appropriate empty/error
result for the caller to handle.
In `@src/libpcp_web/src/search.h`:
- Around line 21-28: Add a concise compatibility-stub comment in search.h
immediately before the retained keys* declarations, identifying keysSearchInit,
keysSearchClose, keys_load_search_schema, and keys_search_text_add as no-op
legacy entry points and warning that they must not be used to build new search
behavior.
In `@src/newhelp/GNUmakefile`:
- Around line 44-45: Update the newhelp$(EXECSUFFIX) target prerequisites to
include search_sqlite.h alongside the existing source files, ensuring changes to
that header trigger recompilation; apply the same prerequisite update to the
corresponding additional rule.
In `@src/newhelp/newhelp.c`:
- Around line 223-271: Update lookup_domain to obtain PCP_VAR_DIR through
pmGetOptionalConfig("PCP_VAR_DIR") instead of opening and parsing PCP_CONF
manually, preserving the existing failure behavior when the configuration value
is unavailable. If file precedence over the environment is required by QA,
document that requirement in the nearby comment with the specific test name.
In `@src/newhelp/search_sqlite.c`:
- Around line 115-116: Update the initial null guard in search_sqlite_open to
also validate search_lookup and search_delete before any statement is used,
while preserving the existing checks for search_db, search_insert, and name.
- Around line 80-82: The upsert lookup in search_sqlite_add must avoid querying
the FTS5 docs table directly, which causes a full scan for each entry. Add or
reuse an external-content/side mapping table keyed by (name, type) with a unique
index, maintain it during document inserts and updates, and change the lookup
around search_lookup to query that indexed mapping while preserving the existing
rowid behavior.

@natoscott Ready for review :). There are a few small changes left (merge conflict for qa test number and coderabbit feedback), but you should be able to build and test the branch as is. |

@sfeifer I ran "./new -r" to reserve test 1861 for you. I'm flatout like a lizard drinking this week though - might get some time on Friday for a look, else next week - hopefully Ken & others have more cycles before then to get you some feedback. |

661-677: 🩺 Stability & Availability | 🔵 TrivialConsider the effect of synchronous queries on the
pmproxyevent loop.
pmSearchTextQuerynow performs the SQLite query inline and invokes the callbacks before it returns.src/pmproxy/src/search.cLine 500 calls it from the request path, which runs on the event loop thread.A local SQLite read is normally fast. Two cases are slower: a broad FTS5 match over a large index, and a query that blocks while the nightly job replaces the index file. During either case
pmproxyserves no other connection.Two mitigations are worth considering:
- Set a busy timeout on the connection with
sqlite3_busy_timeout, so a locked database returns promptly instead of failing immediately.- Add a query progress handler or a row cap, so one broad query cannot occupy the loop without bound.

Inline comments:
In `@man/man1/pmsearch_daily.1`:
- Around line 37-53: Update the pmsearch_daily description to distinguish
shipped base help text from runtime data: state that it copies the base index
and extends it with runtime metric and instance data, rather than saying it
queries help text from pmcd or an archive. Preserve the existing explanation of
the resulting index location and nightly refresh behavior.
In `@qa/1861`:
- Line 54: Update every pmsearch invocation in qa/1861, including the command
using -C "qa_python" and the invocations identified at lines 85, 89, 93, 97, and
102, to pipe or otherwise apply the same sed substitution that replaces $tmp
with TMP. Preserve the existing pmsearch arguments and output behavior while
ensuring temporary paths are normalized.
- Around line 18-21: Add a `_notrun` capability check in the `newhelp` setup
near the existing `which newhelp` guard by executing `newhelp -S` with harmless
input and redirecting output; skip the test when that command fails, while
preserving the existing binary-presence check.
In `@src/libpcp_web/src/search.c`:
- Around line 500-524: Update search_indom_table and its caller
search_do_text_indom to accept request->count and request->offset, adding and
binding SQL LIMIT/OFFSET in both indom query variants so only the requested
window is materialized. Add a separate COUNT(*) query, following
search_count_table, so hits[i].total remains the full indom match count rather
than the paginated row count.
In `@src/newhelp/newhelp.c`:
- Around line 363-390: Set status = 1 before each early return for malformed
entries: both missing-tab branches in the metric parsing logic around the metric
entry handler, and the instance-entry validation near the existing check around
line 324. Preserve the current diagnostics and return behavior while matching
the legacy newentry() error-status handling.
In `@src/pmsearch/GNUmakefile`:
- Around line 61-68: Add the configured SD_SERVICE_TYPE substitution to the
pmsearch_daily.service generation recipe, alongside the existing CRONTAB_PATH,
PCP_BINADM_DIR, PCP_VAR_DIR, PCP_GROUP, and PCP_USER replacements, so the
generated unit replaces `@SD_SERVICE_TYPE`@ with the selected value.
In `@src/pmsearch/pmsearch_daily.service.in`:
- Around line 10-13: Create and package the `@PCP_VAR_DIR`@/lib directory with
ownership or permissions allowing `@PCP_USER`@ to write, so the pmsearch_daily
service can create and update its index while retaining the existing service
configuration.
In `@src/pmsearch/pmsearch_daily.sh`:
- Around line 224-227: Before the mv operation in the index rebuild flow,
explicitly set $NEW to a world-readable mode matching the packaged base index,
such as 0644, after newhelp creates it and before renaming it to $INDEX.
Preserve the existing creation and rename logic.
- Around line 117-121: Update the help-text processing pipeline writing
`$tmp/helptext` so every line beginning with `@` is prefixed with a space before
`newhelp` consumes it; preserve existing filtering of `Help:` and `Full Help:
Error:` lines and leave other lines unchanged.

@sfeifer the build fails on systems with no sqlite... this should not be a hard error, just warn and keep going. |
|
@sfeifer its working pretty well! (haven't gone through the code, just from using it). I suspect the indom help text is not being indexed though? Try "NUMA" as search term - this should hit multiple indom help text entries in the Linux kernel PMDA, but all I see are metric names and metric help text? If there's a priority/ranking option - rank indom help text highly when indexing, any hit there is super important and very likely relevant (there's also far fewer of these docs than the metric help text, so any kind of boost we can give indom help would be good). |
|
@natoscott Thanks for taking a look!
Should this be a warning instead of an error for rpm builds too, or just when building from source on systems without sqlite installed?
I'm still working through the kinks locally, but I added to the SQL query in search_query_table in search.c to multiple the score by 1.5 for indom help text. This was just my first attempt and I'm thinking of increasing that multiple to as high as I can without causing totally bad results. |
Replace the RediSearch/Valkey dependency with a local SQLite FTS5 full-text search index. This makes pmsearch work out of the box without requiring any external services. Build system: add SQLite3 detection via pkg-config with fallback to AC_CHECK_LIB (configure.ac, builddefs.in). Index builder: add newhelp -S mode that parses help text files and builds a SQLite FTS5 database with porter/unicode61 tokenization, BM25 scoring weights, and prefix indexes (search_sqlite.c/.h, newhelp.c). Search engine: rewrite search.c to query local SQLite indexes instead of Redis. Dual-index strategy: nightly index at $PCP_VAR_DIR/lib/pcp.search (instance names + third-party PMDAs) and build-time index at $PCP_SHARE_DIR/lib/pcp.search (all shipped PMDA help text). Both are queried together via ATTACH DATABASE. CLI: remove libuv dependency from pmsearch, make it synchronous. Remove -h/-p host/port options (no remote server needed). Build-time index: generate from all PMDA help files during make install in src/pmdas/GNUmakefile. Nightly index: add pmsearch_index.sh script with systemd timer and cron fallback for daily index rebuilds capturing runtime instance names. Man pages: update pmsearch.1, pmsearchsetup.3, pmsearchinfo.3, pmsearchtextsuggest.3 to describe local SQLite index. Add new pmsearch_index.1 man page.
Propagate sqlite3_CFLAGS from pkg-config through builddefs so that sqlite3.h is found during compilation of search.c and search_sqlite.c. Add sqlite-devel to the RPM spec BuildRequires.
Fix FTS5 queries against the attached base index. SQLite FTS5
functions (bm25, highlight) and MATCH require the bare table name
("docs"), while FROM uses the schema-qualified name ("base.docs").
Split the table parameter into separate "from" and "fts" arguments
in search_query_table, search_suggest_table, and search_indom_table.
Fix build-time index install to write pcp.search to a local temp
file then use $(INSTALL) to copy it to $(PCP_SHARE_DIR)/lib/ so
that DIST_ROOT and DIST_MANIFEST are handled correctly for RPM
packaging. Add pcp.search to LDIRT for make clean.
Regenerate configure from configure.ac to include the SQLite3
pkg-config detection block.

🌐 Web query:
SQLite FTS5 column filter colspec applies only to following phrase parentheses subexpression
💡 Result:
In SQLite FTS5, a column filter (colspec) does not apply only to the immediately following phrase; its scope can be broader depending on the syntax used [1][2]. A column filter can be applied in the following ways: 1. To a single phrase or NEAR group: By prefixing the phrase or NEAR group with the column name (or a list of columns in braces) followed by a colon [1][3]. 2. To an arbitrary expression: By enclosing the expression in parentheses and prefixing the parenthesized group with the column filter [1][4]. In this case, the filter applies to all phrases contained within the parentheses [1][5]. It is important to note that nested column filters can only further restrict the set of columns matched; they cannot be used to re-enable columns that were filtered out by an outer scope [1][2]. Additionally, column filters may be specified by using the column name as the left-hand side of a MATCH operator, which is equivalent to applying that filter to the entire expression on the right-hand side [4][5].

Line 158 computes *maxhits * 2 in int, and line 161 tests the result. Signed overflow is undefined behaviour, so the test reads a value that is already undefined. Check the bound first. The nhits parameter is also unused.
As per path instructions: "Integer overflow: check arithmetic on untrusted sizes".

return -ENOMEM;

tmp = realloc(*hits, (size_t)newmax * sizeof(pmSearchTextResult));Update the three call sites at lines 257, 407 and 532 accordingly.

Handle an empty suggest query.
If request->query is empty, the builder produces name : (*). That expression has no token before the *, so FTS5 rejects it, search_suggest_table returns -EIO, and the client receives an error instead of an empty result set. pmSearchTextSuggest checks only for a NULL query at line 690.
Return an empty result set when the built token list is empty.

Validate the index schema before you accept it.
sqlite3_open_v2 does not read the database header or schema. A truncated, empty or non-SQLite file opens successfully in SQLITE_OPEN_READONLY mode. smd->loaded then becomes 1 for the nightly path, the fallback to the packaged base index at lines 817-822 never runs, and every later query fails with -EIO.
pmsearch_daily writes the nightly file, so a partially written or truncated file is a reachable state. Probe the schema after each open and treat a failure as "index not usable".

As described in #2654 , we want to reimplement pmsearch to no longer depend on RediSearch and instead depend on sqlite, a much more common package.
