| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | r313439: Merge content from ^/projects/netbsd-tests-upstream-01-2017 into ^/head The primary end-goal of this drop is ease future merges with NetBSD and collaborate further with the NetBSD project. The goal was (largely, not completely as some items are still oustanding in the NetBSD GNATS system) achieved by doing the following: - Pushing as many changes required to port contrib/netbsd-tests back to NetBSD as possible, then pull the upstream applied changes back in to FreeBSD. - Diff reduce with upstream where possible by: -- Improving libnetbsd header, etc compat glue. -- Using _SED variables to modify test scripts on the fly for items that could not be upstreamed to NetBSD. As a bonus for this work, this change also introduces testcases for uniq(1). Many thanks to Christos for working with me to get many of the changes back into the NetBSD project. In collaboration with: Christos Zoulas <christos@netbsd.org> r314450: Add additional __FreeBSD_version guards around the hsearch_r testcases The reasoning for this is the same as r276046: to ease MFCing the tests to ^/stable/10 .

| | | | | | | | | | | | | | | | | | | | | | | | | Rework tty_drain() to poll the hardware for completion, and restore drain timeout handling to historical freebsd behavior. The primary reason for these changes is the need to have tty_drain() call ttydevsw_busy() at some reasonable sub-second rate, to poll hardware that doesn't signal an interrupt when the transmit shift register becomes empty (which includes virtually all USB serial hardware). Such hardware hangs in a ttyout wait, because it never gets an opportunity to trigger a wakeup from the sleep in tty_drain() by calling ttydisc_getc() again, after handing the last of the buffered data to the hardware. Restructure the tty_drain loop so that device-busy is checked one more time after tty_timedwait() returns an error only if the error is EWOULDBLOCK; other errors cause an immediate return. This fixes the case of the tty disappearing while in tty_drain(). Check tty_gone() after allocating IO buffers. The tty lock has to be dropped then reacquired due to using M_WAITOK, which opens a window in which the tty device can disappear. Check for this and return ENXIO back up the call chain so that callers can cope. Correct the comments about how much buffer is allocated.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix error reporting from wcstof() When wcstof() skipped initial space and then parsing failed, it set endptr to the first non-space character. Fix it to correctly report failure by setting endptr to the beginning of the input string. The fix is from theraven@, who fixed this bug in wcstod() and wcstold() in r227753. While I'm here: Move assignments out of declarations in wcstod() and wcstold(). This is against my personal preference, but it is our agreed style(9). Set endptr correctly on malloc() failure in all three functions. Remove an incorrect comment: This is pointer arithmetic, so the code was not actually making that assumption. wcstold() advanced the wcp pointer beyond leading whitespace and then reset it back to the beginning of the string. Do not reset it. This seems to have no functional effect, since strtold_l() also skips leading whitespace. I'm making the change to keep this function consistent with wcstof() and wcstod(), and because the C11 spec prescribes the use of iswspace() to skip leading space.

| | | | | | | | | | | | | | | | | | | | | | Improve typing of POSIX search tree functions. Back in 2015 when I reimplemented these functions to use an AVL tree, I was annoyed by the weakness of the typing of these functions. Both tree nodes and keys are represented by 'void *', meaning that things like the documentation for these functions are an absolute train wreck. To make things worse, users of these functions need to cast the return value of tfind()/tsearch() from 'void *' to 'type_of_key **' in order to access the key. Technically speaking such casts violate aliasing rules. I've observed actual breakages as a result of this by enabling features like LTO. I've filed a bug report at the Austin Group. Looking at the way the bug got resolved, they made a pretty good step in the right direction. A new type 'posix_tnode' has been added to correspond to tree nodes. It is still defined as 'void' for source-level compatibility, but in the very far future it could be replaced by a proper structure type containing a key pointer.
