Daniel Stenberg 9aa2afc3a5 Curl_socket_check: add extra check to avoid integer overflow 2016-10-18 09:45:34 +02:00
Jay Satiro aec0c993cb url: skip to-be-closed connections when pipelining (follow-up)
- Change back behavior so that pipelining is considered possible for
connections that have not yet reached the protocol level.

This is a follow-up to e5f0b1a which had changed the behavior of
checking if pipelining is possible to ignore connections that had
'bits.close' set. Connections that have not yet reached the protocol
level also have that bit set, and we need to consider pipelining
possible on those connections.

win: fix Universal Windows Platform build
This fixes a merge error in commit 7f3df80 caused by commit 332e8d6.

Additionally, this changes Curl_verify_windows_version for Windows App
builds to assume to always be running on the target Windows version.
There seems to be no way to determine the Windows version from a
UWP app. Neither GetVersion(Ex), nor VerifyVersionInfo, nor the
Version Helper functions are supported.

Rider Linden e5f0b1ab43 url: skip to-be-closed connections when pipelining
No longer attempt to use "doomed" to-be-closed connections when
pipelining. Prior to this change connections marked for deletion (e.g.
timeout) would be erroneously used, resulting in sporadic crashes.

As originally reported and fixed by Carlo Wood (origin unknown).

Daniel Stenberg 8238ba9c5f ftp: fix Curl_ftpsendf()
... it no longer takes printf() arguments since it was only really taken
advantage by one user and it was not written and used in a safe
way. Thus the 'f' is removed from the function name and the proto is
changed.

Although the current code wouldn't end up in badness, it was a risk that
future changes could end up springf()ing too large data or passing in a
format string inadvertently.

Daniel Stenberg 9885c9508e formpost: avoid silent snprintf() truncation
The previous use of snprintf() could make libcurl silently truncate some
input data and not report that back on overly large input, which could
make data get sent over the network in a bad format.

Example:

 $ curl --form 'a=b' -H "Content-Type: $(perl -e 'print "A"x4100')"

Cokie with the same domain but different tailmatching property are now
considered different and do not replace each other.  If header contains
following lines then two cookies will be set: Set-Cookie: foo=bar;

stored tokens to foo.com Chrome, Opera, Firefox store send them in the
stored order, while Safari pre-sort the cookies.

Daniel Stenberg de71e68000 openssl: don’t call CRYTPO_cleanup_all_ex_data
The OpenSSL function CRYTPO_cleanup_all_ex_data() cannot be called
multiple times without crashing - and other libs might call it! We
basically cannot call it without risking a crash. The function is a
no-op since OpenSSL 1.1.0.

Not calling this function only risks a small memory leak with OpenSSL <
1.1.0.

Daniel Stenberg d93215621f openssl: fix per-thread memory leak usiong 1.0.1 or 1.0.2
OpenSSL 1.0.1 and 1.0.2 build an error queue that is stored per-thread
so we need to clean it when easy handles are freed, in case the thread
will be killed in which the easy handle was used. All OpenSSL code in
libcurl should extract the error in association with the error already
so clearing this queue here should be harmless at worst.

Olivier Brunel 4b86113f5e speed caps: not based on average speeds anymore
Speed limits (from CURLOPT_MAX_RECV_SPEED_LARGE &
CURLOPT_MAX_SEND_SPEED_LARGE) were applied simply by comparing limits
with the cumulative average speed of the entire transfer; While this
might work at times with good/constant connections, in other cases it
can result to the limits simply being "ignored" for more than "short
bursts" (as told in man page).

Consider a download that goes on much slower than the limit for some
time (because bandwidth is used elsewhere, server is slow, whatever the
reason), then once things get better, curl would simply ignore the limit
up until the average speed (since the beginning of the transfer) reached
the limit.  This could prove the limit useless to effectively avoid
using the entire bandwidth (at least for quite some time).

So instead, we now use a "moving starting point" as reference, and every
time at least as much as the limit as been transferred, we can reset
this starting point to the current position. This gets a good limiting
effect that applies to the "current speed" with instant reactivity (in
case of sudden speed burst).
