CHANGELOG

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[Unreleased]

Added

• #712 Added support to integrate Shlink with a mercure hub server.

  Thanks to that, Shlink will be able to publish events that can be consumed in real time.

  For now, two topics (events) are published, when new visits occur. Both include a payload with the visit and the shortUrl:

    * A visit occurs on any short URL: `https://shlink.io/new-visit`.
    * A visit occurs on short URLs with a specific short code: `https://shlink.io/new-visit/{shortCode}`.
  

  The updates are only published when serving Shlink with swoole.

  Also, Shlink exposes a new endpoint GET /rest/v2/mercure-info, which returns the public URL of the mercure hub, and a valid JWT that can be used to subsribe to updates.

• #673 Added new [GET /visits] rest endpoint which returns basic visits stats.

1.21.1 - 2020-01-02

Added

• Nothing

Changed

• Nothing

Deprecated

• Nothing

Removed

• Nothing

Fixed

• #596 Fixed error when trying to download GeoLite2 database due to changes on how to get the database files.

1.21.0 - 2019-12-29

Added

• #118 API errors now implement the problem details standard.

  In order to make it backwards compatible, two things have been done:

  • Both the old error and message properties have been kept on error response, containing the same values as the type and detail properties respectively.
  • The API v2 has been enabled. If an error occurs when calling the API with this version, the error and message properties will not be returned.

  After Shlink v2 is released, both API versions will behave like API v2.

• #575 Added support to filter short URL lists by date ranges.

  • The GET /short-urls endpoint now accepts the startDate and endDate query params.
  • The short-urls:list command now allows --startDate and --endDate flags to be optionally provided.

• #338 Added support to asynchronously notify external services via webhook, only when shlink is served with swoole.

  Configured webhooks will receive a POST request every time a URL receives a visit, including information about the short URL and the visit.

  The payload will look like this:

  {
    "shortUrl": {},
    "visit": {}
  }
  

  The shortUrl and visit props have the same shape as it is defined in the API spec.

Changed

• #492 Updated to monolog 2, together with other dependencies, like Symfony 5 and infection-php.
• #527 Increased minimum required mutation score for unit tests to 80%.
• #557 Added a few php.ini configs for development and production docker images.

Deprecated

• Nothing

Removed

• Nothing

Fixed

• #570 Fixed shlink version generated for docker images when building from develop branch.

1.20.3 - 2019-12-23

Added

• Nothing

Changed

• Nothing

Deprecated

• Nothing

Removed

• Nothing

Fixed

• #585 Fixed PHP Fatal error: Uncaught Error: Class 'Shlinkio\Shlink\LocalLockFactory' not found happening when running some CLI commands.

1.20.2 - 2019-12-06

Added

• Nothing

Changed

• Nothing

Deprecated

• Nothing

Removed

• Nothing

Fixed

• #561 Fixed db:migrate command failing because yaml extension is not installed, which makes config file not to be readable.
• #562 Fixed internal server error being returned when renaming a tag to another tag's name. Now a meaningful API error with status 409 is returned.
• #555 Fixed internal server error being returned when invalid dates are provided for new short URLs. Now a 400 is returned, as intended.

1.20.1 - 2019-11-17

Added

• #519 Documented how to customize web workers and task workers for the docker image.

Changed

• Nothing

Deprecated

• Nothing

Removed

• Nothing

Fixed

• #512 Fixed query params not being properly forwarded from short URL to long one.
• #540 Fixed errors thrown when creating short URLs if the original URL has an internationalized domain name and URL validation is enabled.
• #528 Ensured db:create and db:migrate commands do not silently fail when run as part of install or update.
• #518 Fixed service which updates Geolite db file to use a local lock instead of a shared one, since every shlink instance holds its own db instance.

1.20.0 - 2019-11-02

Added

• #491 Added improved short code generation logic.

  Now, short codes are truly random, which removes the guessability factor existing in previous versions.

  Generated short codes have 5 characters, and shlink makes sure they keep unique, while making it backwards-compatible.

• #418 and #419 Added support to redirect any 404 error to a custom URL.

  It was already possible to configure this but only for invalid short URLs. Shlink now also support configuring redirects for the base URL and any other kind of "not found" error.

  The three URLs can be different, and it is already possible to pass them to the docker image via configuration or env vars.

  The installer also asks for these two new configuration options.

• #497 Officially added support for MariaDB.

Changed

• #458 Updated coding styles to use shlinkio/php-coding-standard v2.0.0.

Deprecated

• Nothing

Removed

• Nothing

Fixed

• #507 Fixed error with too long original URLs by increasing size to the maximum value (2048) based on the standard.
• #502 Fixed error when providing the port as part of the domain on short URLs.
• #509 Fixed error when trying to generate a QR code for a short URL which uses a custom domain.
• #522 Highly mitigated errors thrown when lots of short URLs are created concurrently including new and existing tags.

1.19.0 - 2019-10-05

Added

• #482 Added support to serve shlink under a sub path.

  The router.base_path config option can be defined now to set the base path from which shlink is served.

  return [
      'router' => [
          'base_path' => '/foo/bar',
      ],
  ];
  

  This option will also be available on shlink-installer 1.3.0, so the installer will ask for it. It can also be provided for the docker image as the BASE_PATH env var.

• #479 Added preliminary support for multiple domains.

  Endpoints and commands which create short URLs support providing the domain now (via query param or CLI flag). If not provided, the short URLs will still be "attached" to the default domain.

  Custom slugs can be created on multiple domains, allowing to share links like https://doma.in/my-compaign and https://example.com/my-campaign, under the same shlink instance.

  When resolving a short URL to redirect end users, the following rules are applied:

  • If the domain used for the request plus the short code/slug are found, the user is redirected to that long URL and the visit is tracked.
  • If the domain is not known but the short code/slug is defined for default domain, the user is redirected there and the visit is tracked.
  • In any other case, no redirection happens and no visit is tracked (if a fall back redirection is configured for not-found URLs, it will still happen).

Changed

• #486 Updated to shlink-installer v2, which supports asking for base path in which shlink is served.

Deprecated

• Nothing

Removed

• #435 Removed translations for error pages. All error pages are in english now.

Fixed

• Nothing

1.18.1 - 2019-08-24

Added

• Nothing

Changed

• #450 Added PHP 7.4 to the build matrix, as an allowed-to-fail env.
• #441 and #443 Split some logic into independent modules.
• #451 Updated to infection 0.13.
• #467 Moved docker image config to main Shlink repo.

Deprecated

• #428 Deprecated preview-generation feature. It will keep working but it will be removed in Shlink v2.0.0

Removed

• #468 Removed APCu extension from docker image.

Fixed

• #449 Fixed error when trying to save too big referrers on PostgreSQL.

1.18.0 - 2019-08-08

Added

• #411 Added new meta property on the ShortUrl REST API model.

  These endpoints are affected and include the new property when suitable:

  • GET /short-urls - List short URLs.
  • GET /short-urls/shorten - Create a short URL (for integrations).
  • GET /short-urls/{shortCode} - Get one short URL.
  • POST /short-urls - Create short URL.

  The property includes the values validSince, validUntil and maxVisits in a single object. All of them are nullable.

  {
    "validSince": "2016-01-01T00:00:00+02:00",
    "validUntil": null,
    "maxVisits": 100
  }
  

• #285 Visit location resolution is now done asynchronously but in real time thanks to swoole task management.

  Now, when a short URL is visited, a task is enqueued to locate it. The user is immediately redirected to the long URL, and in the background, the visit is located, making stats to be available a couple of seconds after the visit without the requirement of cronjobs being run constantly.

  Sadly, this feature is not enabled when serving shlink via apache/nginx, where you should still rely on cronjobs.

• #384 Improved how remote IP addresses are detected.

  This new set of headers is now also inspected looking for the IP address:

  • CF-Connecting-IP
  • True-Client-IP
  • X-Real-IP

• #440 Created db:create command, which improves how the shlink database is created, with these benefits:

  • It sets up a lock which prevents the command to be run concurrently.
  • It checks of the database does not exist, and creates it in that case.
  • It checks if the database tables already exist, exiting gracefully in that case.

• #442 Created db:migrate command, which improves doctrine's migrations command by generating a lock, preventing it to be run concurrently.

Changed

• #430 Updated to shlinkio/php-coding-standard 1.2.2
• #305 Implemented changes which will allow Shlink to be truly clusterizable.
• #262 Increased mutation score to 75%.

Deprecated

• Nothing

Removed

• Nothing

Fixed

• #416 Fixed error thrown when trying to locate visits after the GeoLite2 DB is downloaded for the first time.
• #424 Updated wkhtmltoimage to version 0.12.5
• #427 and #434 Fixed shlink being unusable after a database error on swoole contexts.

1.17.0 - 2019-05-13

Added

• #377 Updated visit:locate command (formerly visit:process) to automatically update the GeoLite2 database if it is too old or it does not exist.

  This simplifies processing visits in a container-based infrastructure, since a fresh container is capable of getting an updated version of the file by itself.

  It also removes the need of asynchronously and programmatically updating the file, which deprecates the visit:update-db command.

• #373 Added support for a simplified config. Specially useful to use with the docker container.

Changed

• #56 Simplified supported cache, requiring APCu always.

Deprecated

• #406 Deprecated PUT /short-urls/{shortCode} REST endpoint in favor of PATCH /short-urls/{shortCode}.

Removed

• #385 Dropped support for PHP 7.1
• #379 Removed copyright from error templates.

Fixed

• Nothing

1.16.3 - 2019-03-30

Added

• Nothing

Changed

• #153 Updated to doctrine/migrations version 2.0.0
• #376 Allowed visit:update-db command to not return an error exit code even if download fails, by passing the -i flag.
• #341 Improved database tests so that they are executed against all supported database engines.

Deprecated

• Nothing

Removed

• Nothing

Fixed

• #382 Fixed existing short URLs not properly checked when providing the findIfExists flag.

1.16.2 - 2019-03-05

Added

• Nothing

Changed

• Nothing

Deprecated

• Nothing

Removed

• Nothing

Fixed

• #368 Fixed error produced when running a SELECT COUNT(...) with ORDER BY in PostgreSQL databases.

1.16.1 - 2019-02-26

Added

• Nothing

Changed

• #363 Updated to shlinkio/php-coding-standard version 1.1.0

Deprecated

• Nothing

Removed

• Nothing

Fixed

• #362 Fixed all visits without an IP address being processed every time the visit:process command is executed.

1.16.0 - 2019-02-23

Added

• #304 Added health endpoint to check healthiness of the service. Useful in container-based infrastructures.

  Call [GET /rest/health] in order to get a response like this:

  HTTP/1.1 200 OK
  Content-Type: application/health+json
  Content-Length: 681
  
  {
    "status": "pass",
    "version": "1.16.0",
    "links": {
      "about": "https://shlink.io",
      "project": "https://github.com/shlinkio/shlink"
    }
  }
  

  The status code can be 200 OK in case of success or 503 Service Unavailable in case of error, while the status property will be one of pass or fail, as defined in the Health check RFC.

• #279 Added new findIfExists flag to the [POST /short-url] REST endpoint and the short-urls:generate CLI command. It can be used to return existing short URLs when found, instead of creating new ones.

  Thanks to this flag you won't need to remember if you created a short URL for a long one. It will just create it if needed or return the existing one if possible.

  The behavior might be a little bit counterintuitive when combined with other params. This is how the endpoint behaves when providing this new flag:

  • Only the long URL is provided: It will return the newest match or create a new short URL if none is found.
  • Long url and custom slug are provided: It will return the short URL when both params match, return an error when the slug is in use for another long URL, or create a new short URL otherwise.
  • Any of the above but including other params (tags, validSince, validUntil, maxVisits): It will behave the same as the previous two cases, but it will try to exactly match existing results using all the params. If any of them does not match, it will try to create a new short URL.

• #336 Added an API test suite which performs API calls to an actual instance of the web service.

Changed

• #342 The installer no longer asks for a charset to be provided, and instead, it shuffles the base62 charset.
• #320 Replaced query builder by plain DQL for all queries which do not need to be dynamically generated.
• #330 No longer allow failures on PHP 7.3 envs during project CI build.
• #335 Renamed functional test suite to database test suite, since that better describes what it actually does.
• #346 Extracted installer as an independent tool.
• #261 Increased mutation score to 70%.

Deprecated

• #351 Deprecated config:generate-charset and config:generate-secret CLI commands.

Removed

• Nothing

Fixed

• #317 Fixed error while trying to generate previews because of global config file being deleted by mistake by build script.
• #307 Fixed memory leak while trying to process huge amounts of visits due to the query not being properly paginated.

1.15.1 - 2018-12-16

Added

• #162 Added non-rest endpoints to swagger definition.

Changed

• #312 Now all config files both in php and json format are loaded from config/params folder, easing users to provided customizations to docker image.
• #226 Updated how table are rendered in CLI commands, making use of new features in Symfony 4.2.
• #321 Extracted entities mappings from entities to external config files.
• #308 Automated docker image building.

Deprecated

• Nothing

Removed

• #301 Removed custom AccessLogFactory in favor of the implementation included in zendframework/zend-expressive-swoole v2.2.0

Fixed

• #309 Added missing favicon to prevent 404 errors logged when an error page is loaded in a browser.
• #310 Fixed execution context not being properly detected, making CloseDbConnectionMiddlware to be always piped. Now the check is not even made, which simplifies everything.

1.15.0 - 2018-12-02

Added

• #208 Added initial support to run shlink using swoole, a non-blocking IO server which improves the performance of shlink from 4 to 10 times.

  Run shlink with ./vendor/bin/zend-expressive-swoole start to start-up the service, which will be exposed in port 8080.

  Adding the -d flag, it will be started as a background service. Then you can use the ./vendor/bin/zend-expressive-swoole stop command in order to stop it.

• #266 Added pagination to GET /short-urls/{shortCode}/visits endpoint.

  In order to make it backwards compatible, it keeps returning all visits by default, but it now allows to provide the page and itemsPerPage query parameters in order to configure the number of items to get.

Changed

• #267 API responses and the CLI interface is no longer translated and uses english always. Only not found error templates are still translated.
• #289 Extracted coding standard rules to a separated package.
• #273 Improved code coverage in repository classes.

Deprecated

• Nothing

Removed

• Nothing

Fixed

• #278 Added missing X-Api-Key header to the list of valid cross domain headers.
• #295 Fixed custom slugs so that they are case sensitive and do not try to lowercase provided values.

1.14.1 - 2018-11-17

Added

• Nothing

Changed

• #260 Increased mutation score to 65%.

Deprecated

• Nothing

Removed

• Nothing

Fixed

• #271 Fixed memory leak produced when processing high amounts of visits at the same time.
• #272 Fixed errors produced when trying to process visits multiple times in parallel, by using a lock which ensures only one instance is run at a time.

1.14.0 - 2018-11-16

Added

• #236 Added option to define a redirection to a custom URL when a user hits an invalid short URL.

  It only affects URLs matched as "short URL" where the short code is invalid, not any 404 that happens in the app. For example, a request to the path /foo/bar will keep returning a 404.

  This new option will be asked by the installer both for new shlink installations and for any previous shlink version which is updated.

• #189 and #240 Added new GeoLite2-based geolocation service which is faster and more reliable than previous one.

  It does not have API limit problems, since it uses a local database file.

  Previous service is still used as a fallback in case GeoLite DB does not contain any IP address.

Changed

• #241 Fixed columns in visit_locations table, to be snake_case instead of camelCase.
• #228 Updated how exceptions are serialized into logs, by using monlog's PsrLogMessageProcessor.
• #225 Performance and maintainability slightly improved by enforcing via code sniffer that all global namespace classes, functions and constants are explicitly imported.
• #196 Reduced anemic model in entities, defining more expressive public APIs instead.
• #249 Added functional-php to ease collections handling.
• #253 Increased user_agent column length in visits table to 512.
• #256 Updated to Infection v0.11.
• #202 Added missing response examples to OpenAPI docs.

Deprecated

• Nothing

Removed

• Nothing

Fixed

• #223 Fixed PHPStan errors produced with symfony/console 4.1.5

1.13.2 - 2018-10-18

Added

• #233 Added PHP 7.3 to build matrix allowing its failure.

Changed

• #235 Improved update instructions (thanks to tivyhosting).

Deprecated

• Nothing

Removed

• Nothing

Fixed

• #237 Solved errors when trying to geo-locate null IP addresses.

  Also improved how visitor IP addresses are discovered, thanks to akrabat/ip-address-middleware package.

1.13.1 - 2018-10-16

Added

• Nothing

Changed

• Nothing

Deprecated

• Nothing

Removed

• Nothing

Fixed

• #231 Fixed error when processing visits.

1.13.0 - 2018-10-06

Added

• #197 Added cakephp/chronos library for date manipulations.

• #214 Improved build script, which allows builds to be done without "jumping" outside the project directory, and generates smaller dist files.

  It also allows automating the dist file generation in travis-ci builds.

• #207 Added two new config options which are asked during installation process. The config options already existed in previous shlink version, but you had to manually set their values.

  These are the new options:

  • Visits threshold to allow short URLs to be deleted.
  • Check the visits threshold when trying to delete a short URL via REST API.

Changed

• #211 Extracted installer to its own module, which will simplify moving it to a separated package in the future.

• #200 and #201 Renamed REST Action classes and CLI Command classes to use the concept of ShortUrl instead of the concept of ShortCode when referring to the entity, and left the short code concept to the identifier which is used as a unique code for a specific Short URL.

• #181 When importing the configuration from a previous shlink installation, it no longer asks to import every block. Instead, it is capable of detecting only new config options introduced in the new version, and ask only for those.

  If no new options are found and you have selected to import config, no further questions will be asked and shlink will just import the old config.

Deprecated

• #205 Deprecated [POST /authenticate] endpoint, and allowed any API request to be automatically authenticated using the X-Api-Key header with a valid API key.

  This effectively deprecates the Authorization: Bearer <JWT> authentication form, but it will keep working.

• As of #200 and #201 REST urls have changed from /short-codes/... to /short-urls/..., and the command namespaces have changed from short-code:... to short-url:....

  In both cases, backwards compatibility has been retained and the old ones are aliases for the new ones, but the old ones are considered deprecated.

Removed

• Nothing

Fixed

• #203 Fixed some warnings thrown while unzipping distributable files.
• #206 An error is now thrown during installation if any required param is left empty, making the installer display a message and ask again until a value is set.

1.12.0 - 2018-09-15

Added

• #187 Included an API endpoint and a CLI command to delete short URLs.

  Due to the implicit danger of this operation, the deletion includes a safety check. URLs cannot be deleted if they have more than a specific amount of visits.

  The visits threshold is set to 15 by default and currently it has to be manually changed. In future versions the installation/update process will ask you about the value of the visits threshold.

  In order to change it, open the config/autoload/delete_short_urls.global.php file, which has this structure:

  return [
  
      'delete_short_urls' => [
          'visits_threshold' => 15,
          'check_visits_threshold' => true,
      ],
  
  ];
  

  Properties are self explanatory. Change check_visits_threshold to false to completely disable this safety check, and change the value of visits_threshold to allow short URLs with a different number of visits to be deleted.

  Once changed, delete the data/cache/app_config.php file (if any) to let shlink know about the new values.

  This check is implicit for the API endpoint, but can be "disabled" for the CLI command, which will ask you when trying to delete a URL which has reached to threshold in order to force the deletion.

• #183 and #190 Included important documentation improvements in the repository itself. You no longer need to go to the website in order to see how to install or use shlink.

• #186 Added a small robots.txt file that prevents 404 errors to be logged due to search engines trying to index the domain where shlink is located. Thanks to @robwent for the contribution.

Changed

• #145 Shlink now obfuscates IP addresses from visitors by replacing the latest octet by 0, which does not affect geolocation and allows it to fulfil the GDPR.

  Other known services follow this same approach, like Google Analytics or Matomo

• #182 The short URL creation API endpoints now return the same model used for lists and details endpoints.

Deprecated

• Nothing

Removed

Fixed

• #188 Shlink now allows multiple short URLs to be created that resolve to the same long URL.

1.11.0 - 2018-08-13

Added

• #170 and #171 Updated [GET /short-codes] and [GET /short-codes/{shortCode}] endpoints to return more meaningful information and make their response consistent.

  The short URLs are now represented by this object in both cases:

  {
      "shortCode": "12Kb3",
      "shortUrl": "https://doma.in/12Kb3",
      "longUrl": "https://shlink.io",
      "dateCreated": "2016-05-01T20:34:16+02:00",
      "visitsCount": 1029,
      "tags": [
          "shlink"
      ],
      "originalUrl": "https://shlink.io"
  }
  

  The originalUrl property is considered deprecated and has been kept for backward compatibility purposes. It holds the same value as the longUrl property.

Changed

• Nothing

Deprecated

• The originalUrl property in [GET /short-codes] and [GET /short-codes/{shortCode}] endpoints is now deprecated and replaced by the longUrl property.

Fixed

• #177 Fixed [GET] /short-codes endpoint returning a 500 status code when trying to filter by tags and searchTerm at the same time.

• #175 Fixed error introduced in previous version, where you could end up banned from the service used to resolve IP address locations.

  In order to fix that, just fill this form including your server's IP address and your server should be unbanned.

  In order to prevent this, after resolving 150 IP addresses, shlink now waits 1 minute before trying to resolve any more addresses.

• #166 Fixed unusual edge case in which visits were not properly counted when ordering by visit and filtering by search term in [GET] /short-codes API endpoint.

• #174 Fixed geolocation not working due to a deprecation on used service.

• #172 Documented missing filtering params for [GET] /short-codes/{shortCode}/visits API endpoint, which allow the list to be filtered by date range.

  For example: https://doma.in/rest/v1/short-urls/abc123/visits?startDate=2017-05-23&endDate=2017-10-05

• #169 Fixed unhandled error when parsing ShortUrlMeta and date fields are already DateTime instances.

1.9.0 - 2018-05-07

Added

• #147 Allowed short URLs to be created on the fly using a single API request, including the API key in a query param.

  This eases integration with third party services.

  With this feature, a simple request to a URL like https://doma.in/rest/v1/short-codes/shorten?apiKey=[YOUR_API_KEY]&longUrl=[URL_TO_BE_SHORTENED] would return the shortened one in JSON or plain text format.
