snare 0.4.13 (2026-05-03)

Split "check queue" and "temporary failure" into two. Previously "there is stuff in the queue" caused snare to initiate "continually wake up if there's a temporary failure".
Simplify timeout checks and remove a race condition.
Ensure that temporary failures do not cause the queue to be viewed as empty.
Reset the timeout before running errorcmd (if it exists). Previously, if the main command exceeded the timeout, errorcmd would immediately be considered to have exceeded the timeout as well.

snare 0.4.12 (2025-05-08)

Update dependencies.

snare 0.4.11 (2024-07-25)

Handle both JSON and urlencoded requests.

snare 0.4.10 (2024-04-02)

Change logging approach. -vvvv now gives more helpful output.
Unbreak ping support.
Allow %x and %? to be used in errorcmd. When cmd fails, the only clue as to why can be its exit code. Previously, snare had no way of transmitting this information to the user: this commit allows using %x and %? (the latter borrowing the similarly named variable from the shell) in errorcmd to access this information.

snare 0.4.9 (2024-01-08)

Remove hyper/tokio in favour of a simple internal HTTP server. This reduces the number of library dependencies by about 25%.
Improve logging: errors, warnings, and information are now differentiated. The -v switch increases the logging level. Defaults to "only report errors".
Default to /bin/sh if $SHELL isn't set when running commands.
Add a system test suite.
Respect DESTDIR, and try to pick a more appropriate location for man pages, in installation.

snare 0.4.8 (2023-03-08)

Update dependencies.

snare 0.4.7 (2023-02-06)

Update dependencies, including moving from the unmaintained json crate to serde_json.

snare 0.4.6 (2022-02-09)

Update dependencies, including a security fix to the regex crate.
Remove mention of reposdir from the documentation: it is deprecated and using it causes a warning.

snare 0.4.5 (2022-02-09)

Update dependencies.

snare 0.4.4 (2021-10-26)

Update dependencies.

snare 0.4.3 (2021-06-11)

Update many dependencies.

snare 0.4.2 (2021-03-17)

Update to tokio 1. Also update other dependencies, avoiding warnings over yanked (old) versions of pin-project-lite.

snare 0.4.1 (2020-12-03)

Documentation improvements, including more secure examples.
Updated dependencies, solving a long-standing slow error leak.

snare 0.4.0 (2020-05-13)

Breaking changes

The email option in match blocks has been replaced by the more generic errorcmd. To obtain the previous behaviour:
```
email = "someone@example.com";
```
should be changed to something like:
```
errorcmd = "cat %s | mailx -s \"snare error: github.com/%o/%r\" someone@example.com";
```
This assumes that the mailx command is installed on your machine. As this example may suggest, errorcmd is much more flexible than email. The syntax of errorcmd is the same as cmd with the addition that %s is expanded to the path of the failed job's combined stderr / stdout.

snare informs users whose config contains email how to update to errorcmd to obtain the previous behaviour.

Minor changes

After daemonisation, all errors are now sent to syslog (previously a few errors could still be sent to stderr).
Fix bug in parsing string escapes, where one character too many was consumed after \".
Use SIGCHLD to listen for child process exit, so that snare does not have to be woken up as often.

snare 0.3.0 (2020-03-08)

Breaking changes

snare now only searches for a configuration file at /etc/snare/snare.conf; as before, you can specify an alternative location for snare.conf via the -c option.
snare always changes its CWD to / (previously CWD was only altered if a user was specified).

Minor changes

When a command fails, the email sent now contains the owner and repository name in the subject.

snare 0.2.0 (2020-03-02)

Breaking changes

The github-block level reposdir option has been removed. The more flexible match-block level cmd has been introduced. In essence:
```
github {
  reposdir = "/path/to/prps";
  ...
}
```
should be changed to:
```
github {
  match ".*" {
    cmd = "/path/to/reposdir/%o/%r %e %j";
  }
}
```
snare informs users whose config contains repodir how to update it.

Minor changes

snare now validates input derived from the webhook request so that it is safe to pass to the shell: GitHub owners, repositories, and events are all guaranteed to satisfy the regular expression [a-zA-Z0-9._-]+ and not to be the strings . or ...
String escapes (e.g. "\"") are now properly processed (previously they were ignored).

snare 0.1.0 (2020-02-13)

First release.
