358c5c0745 strlcat: remove function 
This function was only used twice, both in places where performance
isn't crucial (socks + if2ip). Removing the use of this function removes
the need to have our private version for systems without it == reduced
amount of code.

Also, in the SOCKS case it is clearly better to fail gracefully rather
than to truncate the results.

This work was triggered by a bug report on the strcal prototype in
strequal.h.

strlcat was added in commit db70cd28 in February 2001!

809c809281 curl-functions.m4: update detection logic of getaddrinfo() thread-safeness 
Take in account that h_errno might be a modifiable lvalue not defined as

dddcd3b042 curl-functions.m4: update detection logic of getaddrinfo() thread-safeness 
Take in account that POSIX standard Issue 7 drops h_errno support. Now, we also
consider getaddrinfo() to be thread-safe when (_POSIX_C_SOURCE >= 200809L) or
(_XOPEN_SOURCE >= 700) independently of whether h_errno exists or not.

c33aee1667 treaded-resolver: better error messages 
Now use gai_strerror() to get proper error messages when getaddrinfo()
has failed. Detect the function in configure.

b1e4dce671 curl-functions: provide xattr function tests that also check number of arguments 2010-11-10 18:26:21 +01:00
Stefan Tomanek
f1db21218b write extended attributes by using fsetxattr 
Instead of reopening the downloaded file, fsetxattr uses the (already
open) file descriptor to attach extended attributes. This makes the
procedure more robust against errors caused by moved or deleted files.

95719fbea6 xattr: add configure check and #ifdefs 
setxattr is a glibc call to set extended attributes, so configure now
checks for it and the code is adapted to only build when the
functionality is present.

7c028a8332 - Markus Duft pointed out in bug #2961796 that even though Interix has a 
poll() function it doesn't quite work the way we want it so we must disable
  it, and he also provided a patch for it.

5b3be2ee35 getaddrinfo is fully thread safe on solaris versions which 
implement the function even when h_errno is not a macro.

The h_errno macro test now only done on systems for which there
is no hard coded knowledge about getaddrinfo's thread safeness.

5e75817d44 Assume that getaddrinfo is thread safe, unless hard coded

a7e4022d6b Related with the threadsafe capability of getaddrinfo: 
- Constantine Sapuntzakis reported that Darwin 6.0 a.k.a. MAC OS X 10.2
  and newer have a threadsafe getaddrinfo.

- Fix Dragonfly BSD triplet detection.

- In case the hard-coded knowledge says that getaddrinfo is threadsafe,
  an additional check is done to verify that h_errno is also defined.
  If h_errno isn't defined, we finally assume that it isn't threadsafe.
  Jamie Lokier provided the inspiration for this extra check.
