Some page elements don't quite respond correctly if the element is not
in view, so should add the setEnsureElementIsInTheViewport() to click,
doubleclick, hover and change step locators.
- check for urls that are wrapped in quotes, eg. 'https://example.com/'
or "https://example.com/" and trim and remove the quotes before adding seed
- tests: add quoted URL to tests, fix old.webrecorder.net test
- deps: update wabac.js, RWP to latest
- logging: reduce error logging for seed lists, only log once that there are duplicates or page limit is reached
- fix for #882
- separate out reading stream response while browser is waiting (not
really async) from actual async loading, this is not handled via
fetchResponseBody()
- unify async fetch into first trying browser networking for regular
GET, fallback to regular fetch()
- load headers and body separately in async fetch, allowing for
cancelling request after headers
- refactor direct fetch of non-html pages: load headers and handle
loading body, adding page async, allowing worker to continue loading
browser-based pages (should allow more parallelization in the future)
- unify WARC writing in preparation for dedup: unified serializeWARC()
called for all paths, WARC digest computed, additional checks for
payload added for streaming loading
- Adds support for YAML-based config for multiple proxies, containing
'matchHosts' section by regex and 'proxies' declaration, allowing
matching any number of hosts to any number of named proxies.
- Specified via --proxyServerConfig option passed to both crawl and
profile creation commands.
- Implemented internally by generating a proxy PAC script which does
regex matching and running browser with the specified proxy PAC script
served by an internal http server.
- Also support matching different undici Agents by regex, for using
different proxies with direct fetching
- Precedence: --proxyServerConfig takes precedence over --proxyServer /
PROXY_SERVER, unless --proxyServerPreferSingleProxy is also provided
- Updated proxies doc section with example
- Updated tests with sample bad and good auth examples of proxy config

Fixes#841
Crawler work toward long URL lists in Browsertrix. This PR moves seed
handling from the arg parser's validation step to the crawler's
bootstrap step in order to be able to async fetch the seed file from a
URL.

- validate --lang values, fail immediately with invalid iso-639-1
country code
- ignore --lang value when using profile, print warning that profile
language takes precedence
- fixes#833
New Feature:
- support 'flow behavior' from JSON specification
- detect .json files via --customBehaviors
- log behavior progress while running
- logging tweaks (via browsertrix-behaviors 0.8.4) to limit logging for
custom behaviors
- differentiate logging for iframes, move more behavior messages to
debug
- move initCrawlState() to happen earlier to ensure Redis logging can happen in case of fatal errors
- docs to be added in separate follow-up PR
Fixes#804
- Site-specific behaviors use behaviorScriptCustom log context (via browsertrix-behaviors 0.8.3)
- Add behavior logs to redis if --logBehaviorsToRedis is set, including non-debug behaviors / behaviorsScript context and all behaviorScriptCustom logs
- Noisy logs from built-in behaviors like autoscroll are now logged to
debug in https://github.com/webrecorder/browsertrix-behaviors/pull/92
and so won't be pushed to Redis for newer versions of the crawler.
- Updates browsertrix-behaviors to 0.8.3 and makes some changes to
log format in tests accordingly.

- set crawl id from collection, not other way around, to ensure unique
redis keyspace for different collections
- by default, set crawl id to unique value based on host and collection,
eg. '@hostname-@id'
- don't include '@id' in collection interpolation, can only used
hostname or timestamp
- fixes issue mentioned / workaround provided in #784
- ci: add docker login + cacheing to work around rate limits
- tests: fix sitemap tests
Fixes#797
The crawler will now exit with a fatal log message and exit code 17 if:
- A Git repository specified with `--customBehavior` cannot be cloned
successfully (new)
- A custom behavior file at a URL specified with `--customBehavior` is
not fetched successfully (new)
- No custom behaviors are collected at a local filepath specified with
`--customBehavior`, or if an error is thrown while attempting to collect
files from a nonexistent path (new)
- Any custom behaviors collected fail `Browser.checkScript` validation
(existing behavior)
Tests have also been added accordingly.
Fixes#798
Also modifies the existing test for link selector validation to check 17
status code on exit when link selectors fail validation.

Fix#584
- Replace interrupted with interruptReason
- Distinct exit codes for different interrupt reasons: SizeLimit (14), TimeLimit (15), FailedLimit (12), DiskUtilization (16)
are used when an interrupt happens for these reasons, in addition to existing reasons BrowserCrashed (10),
SignalInterrupted (11) and SignalInterruptedForce (13)
- Doc fix to cli args

- follow up to #743
- page retries are simply added back to the same queue with `retry`
param incremented and a higher scope, after extraHops, to ensure retries
are added at the end.
- score calculation is: `score = depth + (extraHops * MAX_DEPTH) +
(retry * MAX_DEPTH * 2)`, this ensures that retries have lower priority
than extraHops, and additional retries even lower priority (higher
score).
- warning is logged when a retry happens, error only when all retries
are exhausted.
- back to one failure list, urls added there only when all retries are
exhausted.
- rename --numRetries -> --maxRetries / --retries for clarity
- state load: allow retrying previously failed URLs if --maxRetries is
higher then on previous run.
- ensure working with --failOnFailedStatus, if provided, invalid status
codes (>= 400) are retried along with page load failures
- fixes#132

…store filename along with page data:
- set filename on crawler load, if not already set, otherwise use
existing
- store filename per crawler instance in <crawlid>:nextWacz

- if redirected page is excluded, block loading of page
- mark page as excluded, don't retry, and don't write to page list
- support generic blocking of pages based on initial page response
- fixes#744
- retries: for failed pages, set retry to 5 in cases multiple retries
may be needed.
- redirect: if page url is /path/ -> /path, don't add as extra seed
- proxy: don't use global dispatcher, pass dispatcher explicitly when
using proxy, as proxy may interfere with local network requests
- final exit flag: if crawl is done and also interrupted, ensure WACZ is
still written/uploaded by setting final exit to true
- hashtag only change force reload: if loading page with same URL but
different hashtag, eg. `https://example.com/#B` after
`https://example.com/#A`, do a full reload
Adds support for autoclick behavior:
- Adds new `autoclick` behavior option to `--behaviors`, but not
enabling by default
- Adds support for new exposed function `__bx_addSet` which allows
autoclick behavior to persist state about links that have already been
clicked to avoid duplicates, only used if link has an href
- Adds a new pageFinished flag on the worker state.
- Adds a on('dialog') handler to reject onbeforeunload page navigations,
when in behavior (page not finished), but accept when page is finished -
to allow navigation away only when behaviors are done
- Update to browsertrix-behaviors 0.7.0, which supports autoclick
- Add --clickSelector option to customize elements that will be clicked,
defaulting to `a`.
- Add --linkSelector as alias for --selectLinks for consistency
- Unknown options for --behaviors printed as warnings, instead of hard
exit, for forward compatibility for new behavior types in the future
Fixes#728, also #216, #665, #31
Fixes#712
- Also expands the existing documentation about behaviors and adds a test.
- Uses query arg for 'branch' and 'path' to specify git branch and subpath in repo, respectively.

Fixes#368
The `--customBehaviors` flag is now an array, making it repeatable. This
should be backwards compatible with the CLI flag, but may require
changes to YAML configs when custom behaviors are used.
Custom behaviors can be loaded from URLs, local filepaths, and paths to
local directories, including any combination thereof.
New tests are added to ensure loading behaviors from URLs as well as a
mixed combination of URL and filepath works as expected.

- if extraHops is set, crawler should visit pages beyond maxDepth
- currently returning out of scope at depth limit even if extraHops is
set
- adjust isInScope and isAtMaxDepth to account for extraHops
- tests: update extra hops test to test extraHops beyond depth
- fixes#693
- Refactors args parsing so that `Crawler.params` is properly timed with
CLI options + additions with `CrawlerArgs` type.
- also adds typing to create-login-profile CLI options
- validation still done w/o typing due to yargs limitations
- tests: exclude slow page from tests for faster test runs
- use existing headersTimeout in undici to limit time to headers fetch
to 30 seconds, reject direct fetch if timeout is reached
- allow full page timeout for loading payload via direct fetch
- support setting global fetch() settings
- add markPageUsed() to only reuse pages when not doing direct fetch
- apply auth headers to direct fetch
- catch failed fetch and timeout errors
- support failOnFailedSeeds for direct fetch, ensure timeout is working
Fixes#674
This PR supersedes #505, and instead of using js-wacz for optimized WACZ
creation:
- generates an 'in-place' or 'streaming' WACZ in the crawler, without
having to copy the data again.
- WACZ contents are streamed to remote upload (or to disk) from existing
files on disk
- CDXJ indices per-WARC are first written to 'warc-cdx' directory, then merged using the linux 'sort' command, and compressed to ZipNum if >50K (or always if using --generateCDX)
- All data in the WARCs is written and read only once
- Should result in significant speed / disk usage improvements:
previously WARC was written once, then read again (for CDXJ indexing),
read again (for adding to new WACZ ZIP), written to disk (into new WACZ
ZIP), read again (if upload to remote endpoint). Now, WARCs are written
once, along with the per-WARC CDXJ, the CDXJ only is reread, sorted and merged on-disk, and all
data is read once to either generate WACZ on disk or upload to remote.

- Adds support for running a SOCKS5 proxy over an SSH connection. This can
be configured by using `--proxyServer ssh://user@host[:port]` config and
also passing an `--sshProxyPrivateKeyFile <private key file>` file param
and an optional `--sshProxyKnownHostsFile <public host key file>`file
param. The key files are expected to be mounted as volumes into the
crawler.
- Same arguments are also available for create-login-profile
- The proxy config uses autossh to establish a more robust connection, and
also waits until a connection can be established before proceeding.
- Docs are updated to include a new 'Crawling with Proxies' page in the user guide
- Tests are updated to include crawling through an SSH proxy running locally.

- instead, exclude sitemap-discovered page URLs from being counted to extra hops rules, eg. if a sitemap page is not in scope, don't include it.
-if extraHops is set with sitemaps, only consider extraHops for links for pages that are in scope.
- bump version to 1.2.4
Fixes#637
- Username will match if name attribute is one of: user, username, email
- Password will match if type is password and name attribute is one of:
pass, password
This loosens the rules sufficiently to solve the issue with the URL in
the linked issue without requiring users to pass custom CSS selectors at
this point.
It looks like we were also using XPath methods like contains whereas
puppeteer expects CSS selectors, hence the syntax change.
Dependency Updates:
- Bump Brave to 1.67.123
- Update puppeteer-core to latest, fixes possible crash when loading
current browser with old profiles
- Tests: simplifies extra hops test to avoid complex pages that could
lead to timeout
Adds enterprise policy to always download PDF and sets download dir to
/dev/null
Moves policies to chromium.json and brave.json for clarity
Further cleanup of non-HTML loading path:
- sets downloadResponse when page load is aborted but response is
actually download
- sets firstResponse when first response finishes, but page doesn't
fully load
- logs that non-HTML pages skip all post-crawl behaviors in one place
- move page extra delay to separate awaitPageExtraDelay() function, applied for all pages (while post-load delay only applied to HTML pages)

It's possible for a redirect, especially a browser-generated one to have
headers and no body (eg. Brave removing tracking url query). Don't
filter these redirects out from being written to WARC, just set payload to empty
buffer.
fixes#627 where Brave-generated redirect response was not stored.

- bump to 1.2.0-beta.3
- parse URL username/password, store in 'auth' field in seed, or pass in 'auth' field directly (from yaml config)
- add 'Authorization' header with base64 encoded basic auth via setExtraHTTPHeaders()
- tests: add test for crawling with auth using http-server using local docs build (now build docs as part of CI)
- docs: add HTTP Auth to YAML config section

Fixes#604
Ensures that extra seeds are propagated to all crawler instances.
Adds a new redis hashmap key to store the extraSeed mappings
url->extraSeeds index, to ensure the extra seeds are added in the same
order on other instances, even if encountered in different order.
Add a new redis lua primitive 'addnewseed' which combines several
operations: check if extra seed already exists and returning existing
index, add new seed to extraSeed list, also add to regular URL seed
list.
