2020-03-07Merge remote-tracking branch 'origin/master' into 5.9Daniel Shahaf21-638/+634
* Test/D02glob.ztst: On the "unreadable directories can be globbed (users/24619, users/24626)" test, resolve conflicts by removing the Cygwin-only skip that has been added in master, since the test is passing on this branch. This effectively reverts workers/45492.

2020-03-0645490 (+45495 and a test): refactor rlimits.cJun-ichi Takimoto3-560/+263
Use a table of known resouces instead of generating rlimits.h by rlimits.awk.
2020-02-27users/24710: Fix job control problem with sudo.Peter Stephenson3-6/+14
If we use kill to test for continued existence of a process group, we should check on failure that the error is ESRCH, as EPERM indicates the group still has memebers but running privileged so should be left alone.
2020-02-2445487: Missing mod_export declarations for AIXPeter Stephenson6-6/+6
2020-02-1845453: builtins: kill: Do not signal current process group when pid is emptyChris Down1-2/+3
The following case was encountered in the wild: % zsh; echo "$?" % trap 'exit 5' TERM % kill '' 5 This behaviour seems more likely to be the result of bugs in programs (e.g. `kill -9 "$unsetvar") rather than being desirable behaviour to me. It also seems unintentional judging by the code and documentation, since it comes about as a result of the fact that: - `isanum` returns true for empty strings (since an empty string technically only consists of digits and minuses...); - `atoi`, when passed a pointer to an invalid number, returns 0; - `kill(0, signal)` sends the signal in question to all processes in the current process group. There are (at least) two ways to solve this issue: 1. Add special handling to `kill` to avoid this case. See this patch[0] for a version that does that. 2. Change how isanum behaves. Since the only two call sites that use it both seem like they should handle the case where the input char array is empty, that seems like a reasonable overall change to me.[1] After this patch: % trap 'exit 5' TERM % kill '' kill: illegal pid: The regression test for `kill` without a sigspec is also included in this commit, as previously it's not possible to test it trivially as it would still kill the test runner in expected-to-fail mode; see discussion in workers/45449. 0: workers/45426: https://www.zsh.org/mla/workers/2020/msg00251.html 1: The other call site using isanum() is the fg builtin, but in that case we just fail later since we can't find any job named '', so no big deal either way. It's the kill case which is more concerning.

* Pass RGID instead of passwd GID to initgroups() * Clean up #ifdefs, avoid unnecessary checks * Flatten conditions
2020-02-14Improve PRIVILEGED fixesDaniel Shahaf4-99/+275
- Fix retval handling in bin_setopt() - Don't skip_setuid / skip_setgid. It's not our place to optimize away noops (that might not even _be_ noops; they might change the saved uid…). - Remove HAVE_* guard checks around functions that are used unguarded elsewhere. - Use bsd-setres_id.c from OpenSSH to provide setresuid() / setresgid() everywhere, and thus simplify the ifdef soup. Fix some preëxisting bugs in the macro definitions of setuid() (do we still need that one?). - Fix zwarning() format codes for variadic arguments type safety - Restored a comment from HEAD - Fix failure modes around initgroups() - Compared privilege restoration code with OpenSSH's permanently_drop_uid() and updated as needed - Add E01 PRIVILEGED sanity checks

2020-02-0245373: Fix ERR_EXIT bug in else branch of if.Peter Stephenson1-1/+1
The flags need resetting for this branch otherwise e.g. command substitution with non-zero status doesn't cause exit.
2020-01-2945343: Queue signals around arithmetic evaluationsDaniel Shahaf2-7/+11
The queueing added in execarith() in 45083 is reverted since the callee does this now.

2020-01-1645304: Do execute the always block even when the try/always block itself is ↵Daniel Shahaf1-1/+1
the last command. Fixes the test added in the previous commit (workers/45305).

2020-01-1545302: bin_umask(): Queue signals around umask().Daniel Shahaf1-1/+4
Otherwise, a signal handler might create files while the temporary umask is in effect.

2020-01-0245181: Fix workers/45164: ${(S)%%} will now consider the empty string as a ↵Daniel Shahaf1-2/+2
potential match.
2019-12-3124581: Fix array assignments in shell word splitting and completion.Peter Stephenson2-1/+13
Assignments after the first were not recognised as such as without the full parser the state didn't return to command position. Fix this in bufferwords() and the completion miniparser.
2019-12-26unposted: zerrmsg(): Fix macro guard missed in previous commitdana1-2/+0
2019-12-26internal: Allow %L in zerrmsg() in non-debug builds, too.Daniel Shahaf1-2/+0
This will let error messages include long integers.
2019-12-2645137: zformat: Allow the specifying minimum width and a dot with an empty ↵Daniel Shahaf1-2/+1
maximum width. Before this commit, format specs such as '%5.s' would be printed literally. Now, they are treated as equivalent to '%5s'. The '.' character is not allowed to be used in specs, so there is no incompatibility.
2019-12-2645138: Add zformat unit tests.Daniel Shahaf1-3/+3
2019-12-2645131: Make a function that redefines itself preserve its tracedness.Daniel Shahaf1-0/+6
This makes it easy to apply local tracing ('functions -T') to autoloadable functions that redefines themselves when first loaded.
2019-12-1845083: Add signal protection to execarith().Peter Stephenson1-0/+3
Otherwise we could get re-entrancy in memory functions when setting variables.
