Changelog of @hackage/ngx-export-tools-extra 1.2.11

1.2.11

• Module NgxExport.Tools.Resolve.
  • A smarter implementation of the internal hashable data HashUQuery.
• Module NgxExport.Tools.PCRE.
  • Replace rareService mode declaration in service declareRegexes by restartPromptly declaration from ngx-export-tools ≥ 1.2.6.

1.2.10

• Module NgxExport.Tools.Resolve.
  • Parameterize collected server data by query data to avoid getting wrong values when multiple instances of the resolve service are running.
  • Use exporters from ngx-export-tools ≥ 1.2.5 which do not share configurations between multiple instances of the resolve service.
  • Append port numbers to values of collected host names as Nginx directive server accepts such a notation.
• Module NgxExport.Tools.PCRE.
  • Replace SingleShotService mode declaration in service declareRegexes by rareService declaration from ngx-export-tools ≥ 1.2.5.

1.2.9.1

• Module NgxExport.Tools.Resolve.
  • By mistake, servers with less weights had higher priorities in A queries.
  • If the number of upstreams in the priority list is less than the number of variations of priorities collected in SRV queries or weights set in QueryA data, then remaining servers with the lowest priorities or weights won't be used in the upstreams.
  • With the PriorityList policy, weights of servers in the collected data are deliberately not specified in A queries. In SRV queries, conversely, weights are not specified with the SinglePriority policy as it is not clear how to choose them correctly from the two parameters priority and weight of the SRV record.

1.2.9

• Module NgxExport.Tools.Resolve.
  • Correctly print IP addresses in the server data collected in A queries.
  • Allow setting weights to names in QueryA data.
  • Allow priority policies in QueryA data.
  • If the number of upstreams in the priority list is greater than the number of variations of priorities collected in SRV queries or weights set in QueryA data, then remaining upstreams will contain the same servers with the lowest priority or weight rather than not being specified at all in the collected data.
  • With the PriorityList policy, weights of servers in the collected data are deliberately not specified.
  • Names in the QueryA name list may contain suffix :port where port is a port number, this suffix is ignored at resolving step in collectA and only appended to values of the collected server addresses.

1.2.8.1

• Module NgxExport.Tools.PCRE.
  • Use voidServer from ngx-export-tools ≥ 1.2.3.
• Module NgxExport.Tools.ServiceHookAdaptor.
  • The test example was improved and extended.

1.2.8

• Module NgxExport.Tools.Subrequest.
  • Allow setting custom HTTP managers in subrequest configurations.
  • In subrequest configurations, field useUDS / srUseUDS is no longer accepted, use "manager": "uds" / srManager = UDS instead.

1.2.7

• Support package base64 1.0.

1.2.6

• Refactored to avoid using head and tail as it triggers x-partial warnings in GHC 9.8.1.
• Use declarations voidHandler, voidHandler', and NgxExportService from package ngx-export-tools 1.2.2.

1.2.5

• Module NgxExport.Tools.Resolve.
  • Function collectSrv now returns a TTL with a list of pairs (Domain name, IP address) wrapped in an SRV container.
  • Collection ServerData now contains the host name.
  • Allow multiple upconf endpoints, secure and insecure.
  • Removed instance FromJSON ServerData.
• Module NgxExport.Tools.PCRE.
  • Removed internal implementation of function compile which now requires pcre-light ≥ 0.4.1.2.

1.2.4

• Added support for https connections in module NgxExport.Tools.Subrequest.

1.2.3

• In module NgxExport.Tools.EDE, custom EDE filters are now passed into function renderEDETemplateWith. The collection of custom EDE filters with b64 and uenc filters is now exported from the module by name extraEDEFilters.

1.2.2

• Added Cabal constraint resolv ≥ 0.2.0.1 to fix memory leaks in module NgxExport.Tools.Resolve.

1.2.1

• Improvements and bug fixes in module NgxExport.Tools.Resolve.
  • Added ability to set response timeout in service collectUpstreams.
  • Use handleAny from safe-exceptions in service collectUpstreams.
  • Improved type declarations and documentation.

1.2.0

• Added module NgxExport.Tools.Resolve which can be used to manage service discovery in Nginx dynamic upstreams.

1.1.0

• Using Network.HTTP.Client.BrReadWithTimeout in module NgxExport.Tools.Subrequest to ensure that a request won't stall on a bad response from a buggy server.
• In module NgxExport.Tools.Subrequest, srBody was reimplemented using lazy bytestrings.

1.0

• Module NgxExport.Tools.Aggregate can now be built without support from the Snap framework (flag SnapAggregateServer replaces flag Aggregate). The module now allows building native Nginx-based aggregate services (see updated docs).
• In module NgxExport.Tools.Aggregate, getting current time with ngxNow was replaced by getCurrentTime because the former is not safe in the async context.
• Removed upper bound restriction in the Cabal constraint on the version of package aeson.
• Package stability tag was promoted to stable.

0.8.2.0

• In module NgxExport.Tools.Subrequest, bridged HTTP subrequests return status code of the source end of the bridge when it returns a non-2xx response.

0.8.1.0

• In module NgxExport.Tools.Subrequest, bridged HTTP subrequests were added.
• In module NgxExport.Tools.Subrequest, configured subrequest headers now get merged with originally set request headers.
• Added Cabal constraint aeson < 2.0.0.0 for building EDE module.

0.6.2.0

• Added Cabal flag Aggregate to build module NgxExport.Tools.Aggregate conditionally.

• Handler extractRequestStatusFromFullResponse was replaced with handler extractExceptionFromFullResponse. The new handler extracts the error message if the subrequest was terminated by an exception.

0.6.0.0

• Using lazy text for encoding Prometheus metrics.

0.5.4.0

• Added handler extractRequestStatusFromFullResponse to retrieve completion status of a subrequest.

0.5.3.0

0.3.0.0

• Added module NgxExport.Tools.Subrequest for making HTTP (sub)requests easily.
