* tests: Fix --stopTavian Barnes2024-02-051-1/+1
|
* tests: Implement jobserver inheritanceTavian Barnes2024-02-034-35/+125
|
* tests: Don't clobber inherited FDsTavian Barnes2024-02-0111-52/+45
| | | | | Rather than attempting to close any unexpected FDs, just count them and adjust our ulimit -n calls to account for them.
* tests: Use variable redirections to dup std{out,err}Tavian Barnes2024-02-012-28/+15
| | | | | | | | | | | Previously, we hardcoded file descriptors 3 and 4 for duplicating stdandard output/error respectively. In preparation for keeping inherited FDs open, switch to using bash's variable redirection feature to dynamically assign FDs. This feature is only available from bash 4.1 onwards, so this marks the end of our support for bash 3. macOS users will need to install a modern bash version to run our tests.
* bftw: Actually stop if the callback returns BFTW_STOPTavian Barnes2024-01-312-0/+5
| | | | | | Otherwise, bftw_ids() or bftw_eds() might keep going! Fixes: 5f16169 ("bftw: Share the bftw_state between iterations of ids/eds")
* tests/posix: Avoid catastrophic backtrackingTavian Barnes2024-01-172-11/+2
| | | | | | Using -path 'deep/*/*/.../*' to simulate -mindepth 18 falls off a performance cliff on systems that use backtracking for fnmatch(). This was observed on macOS 12.4. Instead, just use -type f.
* tests: Properly filter escape sequences with --verbose=testsTavian Barnes2024-01-131-1/+1
|
* bfstd: New {error,errno}_is_like() functionsTavian Barnes2024-01-131-14/+3
| | | | | | | We used to have is_nonexistence_error() to consistently treat ENOENT and ENOTDIR the same. Recently, we started considering EFAULT the same as ENAMETOOLONG on DragonFly BSD to work around a kernel bug. Unify both of these behind a more generic interface.
* tests.h: Add a header guardTavian Barnes2024-01-131-0/+5

| | | | | | | | | | | | | | | | | | POSIX says > When using the symbolic mode form on a regular file, it is > implementation-defined whether or not: > > - Requests to set the set-user-ID-on-execution or set-group-ID-on- > execution bit when all execute bits are currently clear and none > are being set are ignored. And indeed, illumos ignores them with a warning: chmod: WARNING: /tmp/bfs.XXXX7KaGWb/rainbow/suid: Execute permission required for set-ID on execution Link: https://pubs.opengroup.org/onlinepubs/9699919799/utilities/chmod.html

* Work around DragonFly BSD kernel bugTavian Barnes2024-01-041-0/+6
| | | | | | | | | DragonFly's x86_64 assembly implementation of copyinstr() checks the wrong pointer when deciding whether to return EFAULT or ENAMETOOLONG, causing it to always return EFAULT for overlong paths. Work around it by treating EFAULT the same as ENAMETOOLONG on DragonFly. Link: https://twitter.com/tavianator/status/1742991411203485713

|
* tests: Fix a possible infinite loopTavian Barnes2023-11-151-2/+4
| | | | | | | | | | | | | | | | | | | The POSIX spec for readdir() [1] says: > If a file is removed from or added to the directory after the most > recent call to opendir() or rewinddir(), whether a subsequent call > to readdir() returns an entry for that file is unspecified. which implies that a loop of readdir()/unlink()/creat() may continue to return new files unendingly. This was even observed on a Linux 6.6 tmpfs mount [2]. It's not clear whether find(1) is also permitted to loop endlessly in this case, but in case it is, let's avoid the whole problem by limiting the -exec to happen at most once.

* Revert "bit: Implement a branchless has_single_bit()"Tavian Barnes2023-11-111-0/+1
| | | | | | Doesn't work for the highest bit due to overflow. This reverts commit 208376ef99da243545efcd6fb02d3469b4c068ed.

* Treat NO_COLOR="" the same as unsetTavian Barnes2023-11-062-0/+32
| | | | | | | | | | | | | | The docs say > Command-line software which adds ANSI color to its output by default > should check for a NO_COLOR environment variable that, when present > and not an empty string (regardless of its value), prevents the > addition of ANSI color. but we were not checking for the empty string.
