mozsearch VS chrono

- code browsing is primitive compared to https://searchfox.org/ (but most code browsing tool are, in comparison)

- my notifications are completely flooded by lots of useless information on GitHub, but that might be fixable

- our CI system (treeherder/taskcluster) scales, works on Linux/Mac/windows/Android and a bunch of version and arch, integrated with all of the other tools mentioned. Things such as auto-running tests based on the content of the patch, automatic categorization and prioritization of intermittent test failures, or auto-recording test failures and offering a pernosco recording showing the issue are just some of the features that we use daily without even thinking

All the time. I would say at least 50% of my code browsing is done from my phone. I make heavily use of the mobile GitHub web interface for this (find-references support has been a godsend, search is still meh, I hate how they keep breaking basic find-in-page with SPA jank). Also Searchfox [0] when I need to comb through Firefox code (fast, excellent, no complaints).

Context: grad student, programming languages and systems research plus a bunch of IoT hacking on my own time. Either elder Gen Z or youngest possible Millennial, depending where you put the cutoff.

[4] is not really a usable 'product'. Livegrep (https://github.com/livegrep/livegrep) was inspired by it and is very usable.

[3] used to be a Google open source project as well, but it fell out of maintenance, and Sourcegraph took it over. It powers most of the basic regex/literal search in Sourcegraph.

Mozilla's code is searchable in Searchfox (https://searchfox.org/) which uses the indexer from Livegrep, combined with their own Git indexer and language-specific cross reference databases.

OpenGrok (https://github.com/oracle/opengrok) is also rather well known, but I have found it to have a slightly worse UI than alternatives.

Try using Searchfox to find references to those libraries. When you open a result, hover your mouse over the left column to see what commit added each line.

You might want to lokk at this, and this, and this .

Layout is hella broken, obviously, but it doesn't crash. You can do a search for progresschunck at https://searchfox.org to find what it means.

https://searchfox.org/ should be you go-to tool to search Firefox code-base.

Also, you can use browser toolbox to inspect Firefox UI and see what styles are being applied to it and to figure out what selectors to use. Of course, there is also https://searchfox.org/ for when you need to figure out exactly how Firefox is doing some feature x.

The problem is that this effects higher languages too, because they often build on libc. And on some OSes, they don't have a choice, because the system call interface is unstable and/or undocumented).

For example in rust, multiple time libraries were found to be unsound if `std::env::set_env` was ever called from a multi-threaded program. See:

> I think library authors should be more relentless and break compatibility every few years. We just need some conventions to not do so very often.

I indeed did this years ago---I'm the original author of Chrono [1]---and it wasn't well received [2] [3] [4]. To be fair, I knew it was a clear violation of semantic versioning but I didn't see any point of obeying that until we've reached 1.0 so I went ahead. People complained a lot and I had to yank the problematic release. By then I realized many enough people religiously expect semantic versioning (for good reasons though) and it's wiser to avoid useless conflict.

On that note, it would also be good to configure cargo-deny so that a CI pipeline and any maintainer can easily audit the current dependency versions. Sometimes CVEs require a new major semver (looking at you, time 0.1.x and thus chrono 0.4.x), so it's not enough to rely on people installing the tool with semver-compatible updates. Automatically auditing dependencies is really important, and given how easy cargo-deny makes it, I don't think many projects have any excuse not to configure it.

The example has been randomly taken from the [Chrono][https://github.com/chronotope/chrono/blob/main/src/offset/utc.rs] crate.

libc isn't "just a wrapper". Is a massive legacy codebase filled with hacks, UBs and bugs: https://github.com/chronotope/chrono/issues/499

Would love to have people test this, you can leave feedback here: https://github.com/chronotope/chrono/issues/674.

Security issues? I'm looking at the open issues, but haven't noticed any that seem to be security related (no security related labels either). What am I missing here?
