Bump check-spelling/check-spelling from 0.0.19 to 0.0.21 #6

dependabot · 2022-11-29T08:16:38Z

Bumps check-spelling/check-spelling from 0.0.19 to 0.0.21.

Release notes

Sourced from check-spelling/check-spelling's releases.

Release 0.0.21

⏩ Upgrading

🏷️ You can just change your workflow tags/references to this release, but some features require updates to the workflow (including sarif output and binary file detection); please consider applying the workflow from check-spelling/spell-check-this@prerelease. (The link will change shortly after this release is made.)

You will want to copy over the with: elements you're using (into each place that uses: check-spelling/check-spelling).

🐣 Breaking Changes

🗜️ Smaller cspell dictionaries

Background

There are 3 related configuration items:

dictionary_source_prefixes

In v0.0.20, this had: "cspell": "https://raw.githubusercontent.com/check-spelling/cspell-dicts/v20220427/dictionaries/"

In v0.0.21, it has: "cspell": "https://raw.githubusercontent.com/check-spelling/cspell-dicts/v20220816/dictionaries/"

extra_dictionaries

check_extra_dictionaries

The list has changed between v0.0.20 and v0.0.21, a bunch have moved, some have split, and a bunch have been added.

Migrating

You can migrate in a couple of ways:

Assuming you haven't set dictionary_source_prefixes, you can temporarily clear extra_dictionaries and check_extra_dictionaries and then use one run to get a new set of recommended extra_dictionaries and then set check_extra_dictionaries (typically to '').

If you want to keep your current cspell extra_dictionaries, change cspell to cspell_old (or anything that isn't cspell) and set dictionary_source_prefixes to something like this: {"cspell": "https://raw.githubusercontent.com/check-spelling/cspell-dicts/v20220816/dictionaries/", "cspell_old": "https://raw.githubusercontent.com/check-spelling/cspell-dicts/v20220427/dictionaries/"}.

Note that the main branch for check-spelling/cspell-dicts will move (roughly at the time of the v0.0.21 release and again for future releases).

🧗 act

Some changes in how the action works require actions/download-artifact and actions/upload-artifact which aren't generally supported by act. It might be possible to use --artifact-server-path, but I don't know how to do it.

Mitigation

You can apply changes equivalent to the changes to .github/workflows/spelling.yml to your workflow. This should enable the act workflows to conspire to share data between jobs. Alternatively, you could remove post_comment: 0 from your spelling job. And that should result in a report.

The log will include a base64 encoded zip file along with instructions to decode it and a command that will let you feed the file to apply.pl to apply its suggestions.

🏛️ Behavior change: File line column notation

Log output will now use a format like .github/workflows/spelling.yml:54:9 ... 21 to report problems. This should be friendlier to automated tools. Anyone who had written their own code to parse the old format will need to adjust their tooling. I don't expect this to be a big concern.

The IO error was not always handled by the proper TCP thread, possibly leading to a race condition where two TCP worker threads were touching the same TCP connection object at the same time. Technically the issue also exists for XFR responses, but these are very unlikely to cross protocols. We are still applying the same fix. The issue was introduced in 516a000. This was reported by Thread Sanitizer: ``` 2023-03-10T13:52:59.5959261Z WARNING: ThreadSanitizer: data race (pid=15423) 2023-03-10T13:52:59.5959559Z Read of size 1 at 0x7b040000385c by thread T2

When `svc-autohints` is enabled, the content of SVCB and HTTPS records is modified in `PacketHandler::doAdditionalProcessing()` to expand the IPv4 and IPv6 with their actual values. This causes an issue because the content of these records might be shared between threads, via the record cache, and one thread could be trying to read from the internal `std::set` while a second thread is altering it, leading to a data race and possibly to memory corruption and a crash. This is correctly detected by TSAN: ``` WARNING: ThreadSanitizer: data race (pid=102795) Write of size 8 at 0x7b3400010350 by thread T33: #0 operator delete(void*) <null> (pdns_server+0x211b7c)

(/work/pdns-rgacogne/pdns/pdns_server+0x211b7c) (BuildId: 384adc19a67695435bd5e89d0a77f562561f4593) in operator delete(void*) ``` To prevent this issue, this commit wraps the internal `std::set` in a mutex. In theory this will cause a performance impact, but in practice I did not find it to be noticeable. If we ever do, a different solution would be to duplicate the content of the SVCB/HTTPS records before modifying them.

When `svc-autohints` is enabled, the content of SVCB and HTTPS records is modified in `PacketHandler::doAdditionalProcessing()` to expand the IPv4 and IPv6 with their actual values. This causes an issue because the content of these records might be shared between threads, via the record cache, and one thread could be trying to read from the internal `std::set` while a second thread is altering it, leading to a data race and possibly to memory corruption and a crash. This is correctly detected by TSAN: ``` WARNING: ThreadSanitizer: data race (pid=102795) Write of size 8 at 0x7b3400010350 by thread T33: #0 operator delete(void*) <null> (pdns_server+0x211b7c)

records before modifying the copy. the drawback is that we need to do this operation every single time we process them.

…mode There is an actual race when one thread, likely the console, changes the health-check mode of a given backend just when the health-check thread is determining whether it should send a health-check probe. We are fine with getting a wrong value in the health-check thread, as long as we eventually get the new one, so let's not worry about it and add a TSAN suppression. The TSAN report was: ``` WARNING: ThreadSanitizer: data race (pid=5301) Read of size 1 at 0x7b78000002ae by thread T11: #0 DownstreamState::healthCheckRequired(std::optional<long>)
