Hengfei Yang c246119809 fix(i18n): stop translated placeholder names crashing localized pages (#13833)
Fixes #13751

## The crash

vue-i18n compiles messages just-in-time (`__INTLIFY_JIT_COMPILATION__`),
and a compile error is **thrown**, not warned — it tears down whatever
component asked for the message. The translation pipeline had been
localizing placeholder *names*, which is exactly that kind of error:

```
en-US  "Are you sure you want to delete {identifier}?"
zh-CN  "您确定要删除 {标识符} 吗?"        -> SyntaxError: 2 (INVALID_TOKEN_IN_PLACEHOLDER)
```

IAM → Service Accounts rendered blank in Chinese for this reason. The
two zh-CN strings named in the issue had already been patched by hand in
#13707, but the *class* was never swept.

## What was actually broken

Compiling every message in every locale file with vue-i18n's own
compiler found three groups:

| | count | symptom |
|---|---|---|
| Does not compile | 132 | page blanks with `SyntaxError` — 8 locales:
es, fr, it, ja, ko, nl, pt, tr |
| Compiles, unknown name | 147 | `{Anzahl}` for `{count}` → value
renders as an empty string |
| Stale text, dropped placeholder | 5 | `{org}`, `{payer}`,
`{endpoint}`, `{service}` — English source no longer has them |

Worst of the first group are mangled vue-i18n literal escapes, e.g.
`{'{'}team{'}'}` coming back as `{'{'} '}` — an unbalanced brace.

All 279 are corrected here. The existing translated prose is kept
verbatim; only the tokens are restored. The 5 stale ones are
retranslated from the current English text, since restoring a token that
no longer exists is not an option.

## Why it can't come back

**`web/src/locales/enUsMessages.spec.ts` already did this — for en-US
only.** That left the machine-translated locales, the actual source of
the bug, uncovered. Renamed to `localeMessages.spec.ts` and extended to
every locale, plus a second assertion that a translation only
interpolates names en-US defines.

That second check is a **subset** rule, not equality: dropping a
placeholder the target language does not need stays legal (an English
plural suffix like `{plural}` has no Japanese equivalent). Introducing a
name en-US never passes a value for is always a bug.

Placeholder names are collected by *running* the compiled message
against a recording context rather than by pattern-matching the source,
because only the compiler knows which braces are placeholders and which
are literal escapes — `{'}'}` is one token whose body is the character a
`{...}` regex stops at. All plural branches are evaluated.

**`scripts/translations/translator.py` — `_validate` had the same regex
blind spot** (`{[^{}]*}`) and never checked that the output compiles at
all, which is why these landed. It now tokenizes the way vue-i18n does
and rejects anything vue-i18n would refuse, so the pipeline stops
emitting them rather than CI merely catching them afterwards. Escape
drift (`{'{'} rows {'} rows {'}`) is caught too, because literal escapes
are now part of the compared token multiset.

## Verification

- The Python scanner was cross-checked against vue-i18n's compiler over
**all 170,055 messages** in the 15 locale files — identical compile
verdicts and identical token sets, 0 divergences.
- Injecting the original `{标识符}` string back into zh-CN fails the new
spec; injecting a compiling-but-wrong `{bilv}` fails the second
assertion.
- `npx vitest run --environment jsdom --root src/ locales/` → 45 passed.
`prettier --check` and `tsc` clean on the spec.
- Only `en-US.json` is imported anywhere in `web/src`, so no existing
test depends on the changed locale data.

## Not in scope

A handful of translations are awkward but compile and bind correctly
(e.g. ko-KR renders "ingestion limit" with the eating sense of the
word). Left alone to keep this diff auditable as a mechanical token
restoration.

Architecture

OpenObserve achieves 140x lower storage costs and high performance through a modern, cloud-native architecture:

  • Parquet columnar storage — efficient compression and fast analytical queries
  • S3-native design — inexpensive object storage with intelligent caching
  • Built in Rust — memory-safe, high-performance, single binary
  • Partitioning, indexing, and smart caching — reduces search space by up to 99% for most queries
  • Native multi-tenancy — organizations and streams as first-class concepts with complete data isolation
  • Stateless architecture — rapid scaling and low RPO/RTO for disaster recovery

Scale & Deployment

  • Thousands of concurrent users can query a single cluster simultaneously
  • Single binary scales to terabytes — unique in the observability space
  • High Availability mode scales to petabytes for the most demanding workloads
  • Multi-region deployments with cluster federation via Super Cluster architecture (Enterprise)
  • Federated search across regions and clusters (Enterprise)

High Availability & Disaster Recovery

Deploy in High Availability mode with clustering for mission-critical workloads requiring maximum uptime. OpenObserve's stateless architecture with S3-backed storage enables very low Recovery Point Objective (RPO) and Recovery Time Objective (RTO): stateless nodes restart rapidly, and durability is guaranteed by S3's 99.999999999% (11 nines).

FAQ

How does OpenObserve achieve 140x lower storage costs?

Through a combination of Parquet columnar storage (efficient compression) and an S3-native architecture (inexpensive object storage). See the cost comparison chart in the Why OpenObserve? section.

What are the limitations?

All data in OpenObserve is immutable — once ingested, it cannot be modified or deleted (only entire retention periods can be dropped). This is by design and is a feature for logs and compliance use cases, ensuring data integrity and audit trails.

Is this production-ready?

Yes. OpenObserve runs in production across thousands of deployments worldwide, including environments processing in excess of 2 PB/day. See our customer stories for real-world examples.

How does query performance compare to Elasticsearch?

OpenObserve delivers better performance than Elasticsearch for most workloads, with faster search and significantly faster analytics — while using about a quarter of the hardware. The columnar Parquet format is particularly effective for complex aggregations and analytics.

Is there a steep learning curve?

No. OpenObserve is designed to be intuitive from day one:

  • Familiar query languages — SQL for logs and traces, PromQL for metrics; no proprietary query language to learn
  • Easy-to-use GUI — an intuitive interface with a drag-and-drop dashboard builder
  • No complex tuning — unlike Elasticsearch, there are no shards, replicas, or heap sizes to manage. Just install and go.

Most users are productive within hours, not weeks.
