* MFC r337666: getopt_long(3): Document behavior, optstring leading charactersKyle Evans2018-08-201-2/+43
| | | | | | | | | | | | | | Leading '+', '-', and ':' in optstring have special meaning. We briefly mention that the first two have special meaning in that we say POSIXLY_CORRECT turns them off, but we don't actually document their meaning. Add a paragraph to RETURN VALUES explaining how they control the treatment of non-option arguments. A leading ':' has no mention; add a note that it suppresses warnings about missing arguments.

| | | | | | | | | | | | | | | | | | | | This was intended to be a non-functional change. It wasn't. The commit message was thus wrong. In addition it broke arm, and merged crypto related code. Revert with prejudice. This revert skips files touched in r316370 since that commit was since MFCed. This revert also skips files that require $FreeBSD$ property changes.

| | | | | | | | | | | | | | | | | | | libc: small cleanups. Rename nitems to numitems: it shares the anme with an existing macro in sys/params.h. Also initialize the value later which avoids asigning the value if we exit early. Unsign setlen: it is local and will never be negative.

The change in performance over a locally mounted UFS filesystem was negligible in my testing, but this may more positively impact other filesystems like NFS.

| | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | Though the buffer used by l64a() is initialized with null bytes, repetetive calls may end up having trailing garbage of previous invocations because we don't end up terminating the string. Instead of importing NetBSD's fix, use this opportunity to simplify this function dramatically, for example by just storing the Base64 character set in a string. There is also no need to do the bitmasking, as we can just use the proper integer type from <stdint.h>.

* Replace implementation of hsearch() by one that scales.Ed Schouten2015-12-277-185/+335
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Traditionally the hcreate() function creates a hash table that uses chaining, using a fixed user-provided size. The problem with this approach is that this often either wastes memory (table too big) or yields bad performance (table too small). For applications it may not always be easy to estimate the right hash table size. A fixed number only increases performance compared to a linked list by a constant factor. This problem can be solved easily by dynamically resizing the hash table. If the size of the hash table is at least doubled, this has no negative on the running time complexity. If a dynamically sized hash table is used, we can also switch to using open addressing instead of chaining, which has the advantage of just using a single allocation for the entire table, instead of allocating many small objects. Finally, a problem with the existing implementation is that its deterministic algorithm for hashing makes it possible to come up with fixed patterns to trigger an excessive number of collisions. We can easily solve this by using FNV-1a as a hashing algorithm in combination with a randomly generated offset basis. Measurements have shown that this implementation is about 20-25% faster than the existing implementation (even if the existing implementation is given an excessive number of buckets). Though it allocates more memory through malloc() than the old implementation (between 4-8 pointers per used entry instead of 3), process memory use is similar to the old implementation as if the estimated size was underestimated by a factor 10. This is due to the fact that malloc() needs to perform less bookkeeping.

* Let tsearch()/tdelete() use an AVL tree.Ed Schouten2015-12-224-86/+473
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The existing implementations of POSIX tsearch() and tdelete() don't attempt to perform any balancing at all. Testing reveals that inserting 100k nodes into a tree sequentially takes approximately one minute on my system. Though most other BSDs also don't use any balanced tree internally, C libraries like glibc and musl do provide better implementations. glibc uses a red-black tree and musl uses an AVL tree. Red-black trees have the advantage over AVL trees that they only require O(1) rotations after insertion and deletion, but have the disadvantage that the tree has a maximum depth of 2*log2(n) instead of 1.44*log2(n). My take is that it's better to focus on having a lower maximum depth, for the reason that in the case of tsearch() the invocation of the comparator likely dominates the running time. This change replaces the tsearch() and tdelete() functions by versions that create an AVL tree. Compared to musl's implementation, this version is different in two different ways: - We don't keep track of heights; just balances. This is sufficient. This has the advantage that it reduces the number of nodes that are being accessed. Storing heights requires us to also access all of the siblings along the path. - Don't use any recursion at all. We know that the tree cannot 2^64 elements in size, so the height of the tree can never be larger than 96. Use a 128-bit bitmask to keep track of the path that is computed. This allows us to iterate over the same path twice, meaning we can apply rotations from top to bottom. Inserting 100k nodes into a tree now only takes 0.015 seconds. Insertion seems to be twice as fast as glibc, whereas deletion has about the same performance. Unlike glibc, it uses a fixed amount of memory. I also experimented with both recursive and iterative bottom-up implementations of the same algorithm. This iterative top-down version performs similar to the recursive bottom-up version in terms of speed and code size. For some reason, the iterative bottom-up algorithm was actually 30% faster for deletion, but has a quadratic memory complexity to keep track of all the parent pointers.

There's no reason for meta mode to do this as make is already handling the rebuild dependency fine. Sponsored by: EMC / Isilon Storage Division Notes: svn path=/head/; revision=291320

| | | | | | | | | | | | | | | | | | | | | | | | | | | are aliases for the syscall stubs and are plt-interposed, to the libc-private aliases of internally interposed sigprocmask() etc. Since e.g. _sigaction is not interposed by libthr, calling signal() removes thr_sighandler() from the handler slot etc. The result was breaking signal semantic and rtld locking. The added __libc_sigprocmask and other symbols are hidden, they are not exported and cannot be called through PLT. The setjmp/longjmp functions for x86 were changed to use direct calls, and since PIC_PROLOGUE only needed for functional PLT indirection on i386, it is removed as well. The PowerPC bug of calling the syscall directly in the setjmp/longjmp implementation is kept as is.
