* contrib: add linter to check for panic handler in goroutinesRobin Jarry2023-01-061-1/+4
| | | | | | | | | | | | | | | | | If log.PanicHandler() is not installed in a goroutine and a panic occurs, the terminal state is not restored. This causes the panic trace to be unreadable since the terminal is broken. Add a custom analyzer that parses our code and ensures that: defer log.PanicHandler() is the first statement of all functions that are executed in goroutines. Include that linter in golangci config.

* contributing: add tooling for git send-emailRobin Jarry2022-12-141-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | Add a gitconfig target in the Makefile to configure a new clone with sane defaults: - set subject prefix - set correct mailing list address - enable sendemail.validate - install sendemail-validate hook The sendemail-validate hook will make a shallow clone of the current upstream repo, apply every patch on it and run some checks (a stripped down version of what is run by the upstream CI). Add a new check-patches script that verifies that the commit message actually contains something and that the Signed-off-by trailer from the patch author is present. Call check-patches in both the CI and the sendemail-validate hook. Update CONTRIBUTING.md accordingly. Signed-off-by: Robin Jarry <robin@jarry.cc> Acked-by: Tim Culverhouse <tim@timculverhouse.com>

* filters: add wrap utility written in goRobin Jarry2022-12-051-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I had started writing this as an awk script but quickly got stuck with obscure code which did not even work properly. I jumped the gun and re did it in go. Bonus, we will not have MacOS's 1987 BSD awk issues. On the other hand, instead of a 20.0K awk script, we now have a 2.2M static go binary. If this makes people scream, I challenge them to do that with BSD awk :) Basically, this takes text from stdin or from a file and wraps long lines on word boundaries. It takes care of not breaking up email quotes nor list items (numbered as well). Also, it is conservative by default and only wraps long lines and lines that end with a space (indicating a format=flowed message). If the AERC_SUBJECT environment variable is defined and contains the word PATCH, the text is not modified at all (i.e. wrap behaves as cat(1)). There are a few command line options to control behavior: Usage of ./wrap: -f string read from file instead of stdin -l int minimum percentage of letters in a line to be considered a paragaph (default 50) -r reflow all paragraphs even if no trailing space -w int preferred wrap margin (default 80) Update docs, makefile and default config file with examples. Add a torture test to ensure it works as expected. Signed-off-by: Robin Jarry <robin@jarry.cc> Tested-by: Bence Ferdinandy <bence@ferdinandy.com>

* lint: check for bad white space habitsRobin Jarry2022-10-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A little coding hygiene cannot hurt. Add a simple awk script to check all source files for bad white space habits: - trailing white space - trailing new lines at the end of files - missing new line at the end of files - spaces followed by tabs The script outputs color when the terminal supports it. It exits with a non-zero code when there was at least one white space issue found. Call the script in the lint step. Example output of the awk script: config/default_styleset:1:# <-- trailing whitespace config/default_styleset:3:# <-- trailing whitespace doc/aerc.1.scd:78: Executes an arbitrary command in the background. Aerc will set the <-- trailing whitespace doc/aerc.1.scd:234: <-- trailing whitespace doc/aerc.1.scd:237: <-- trailing whitespace worker/types/thread_test.go:74: // return ErrSkipThread<-- space(s) followed by tab(s) worker/lib/testdata/message/invalid/hexa: trailing new line(s) Fix issues reported by the script. NB: The ENDFILE match is a GNU extension. It will be ignored on BSD-awk and trailing new lines will not be detected. The lint make target is only invoked on alpine linux which has GNU awk anyway. NB: Empty cells in scdoc tables require trailing white space... Avoid this by setting content in these cells. I don't really see a use for empty cells.

* mk: exclude govulncheck from lintRobin Jarry2022-10-071-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The vulnerability database is evolving with time. It can cause the lint step to fail suddenly without any source code changes on our side. Moreover, sometimes, there is nothing we can do to fix the issue nor to silence that specific error. Found 1 known vulnerability. Vulnerability #1: GO-2022-1039 Programs which compile regular expressions from untrusted sources may be vulnerable to memory exhaustion or denial of service. The parsed regexp representation is linear in the size of the input, but in some cases the constant factor can be as high as 40,000, making relatively small regexps consume much larger amounts of memory. After fix, each regexp being parsed is limited to a 256 MB memory footprint. Regular expressions whose representation would use more space than that are rejected. Normal use of regular expressions is unaffected. Call stacks in your code: config/config.go:1000:46: git.sr.ht/~rjarry/aerc/config.AercConfig.LoadBinds calls regexp.Compile, which eventually calls regexp/syntax.Parse Found in: regexp/syntax@go1.18.6 Fixed in: regexp/syntax@go1.19.2 More info: https://pkg.go.dev/vuln/GO-2022-1039 Move govulncheck into its own make target to be executed manually.

| | | | | | | | | | | | | | | | | | The LDFLAGS environment variable is usually indented for C the linker flags which are not compatible with go -ldflags. Use a more explicit GO_LDFLAGS variable instead. Allow adding extra flags without overriding the default ones by specifying GO_EXTRA_LDFLAGS. This may break the build on some distros that rely on setting LDFLAGS to change the default shareDir or version. They will have to switch to GO_EXTRA_LDFLAGS.

* mk: fix dynamic source dependencies with bsd makeRobin Jarry2022-02-271-1/+1
| | | | | | | | | | | | | | | | | When building with BSD make, running `make` after updating a source file will not cause the binary to be rebuilt. After inspection, it appears that the GOSRC variable only contains "go.mod go.sum". The aerc target does not depend on .go source files. The $(shell) construct is GNU make specific. BSD make has a special assignment operator (!=) which evaluates a shell command. Since GNU make 4.0, the BSD != operator is supported for compatibility. Use a syntax that is available in both make flavours.
