We found a problem with ftp transfer using libcurl (7.23 and 7.25)
inside an application which is receiving unix signals (SIGUSR1,
SIGUSR2...) almost continuously. (Linux 2.4, PowerPC, HAVE_POLL_FINE
defined).
Curl_socket_check() uses poll() to wait for the socket, and retries it
when a signal is received (EINTR). However, if a signal is received and
it also happens that the timeout has been reached, Curl_socket_check()
returns -1 instead of 0 (indicating an error instead of a timeout).
In our case, the result is an aborted connection even before the ftp
banner is received from the server, and a return value of
CURLE_OUT_OF_MEMORY from curl_easy_perform() (Curl_pp_multi_statemach(),
in pingpong.c, actually returns OOM if Curl_socket_check() fails :-)
Funny to debug on a system on which OOM is a possible cause).

bug #3544688 "crash during retry with libcurl and SFTP"
|
|
Due to WSAPoll bugs, libcurl does not work as intended. When the cURL
library is used to setup a connection to an incorrect port, normally the
result is CURLE_COULDNT_CONNECT, /* 7 */, but due to the bug in WSAPoll,
the result now is CURLE_OPERATION_TIMEDOUT, /* 28 - the timeout time was
reached */.
On August 1, Jan Koen Annot opened a case for this to Microsoft Premier
Online (https://premier.microsoft.com/). The support engineer handling
the case wrote that the case description is quite clear. He will try to
reproduce the issue and then proceed with troubleshooting it.

When figuring out if the data stream needs to be rewound when the
request is to be resent, we must not access the HTTP struct unless the
protocol used is indeed HTTP...

Braces, not parentheses, should be used for shell variable names.

Stupid lack of range checks caused the code to overwrite local variables
after glob number nine. Added checks now.

Fix a bug where closed sockets (fd -1) were left in the all_sockets
list, because of missing parens in a pointer arithmetic expression
Reenable the tests that were locking up due to this bug.

The tests 2025, 2028 and 2031 don't work for me so I'll have them
disabled for now until we solve the problem.

the O_NONBLOCK and
SO_KEEPALIVE flag to all sockets. Note that several loops which used to continue on a return value
of 0 (theoretical since 0 would never be returned without O_NONBLOCK) now break on 0 so that they
won't continue reading until after poll is called again.
|
|
service_connection to add a return code
for non-blocking sockets: now -1 means error or connection finished, 1 means data was read, and 0
means there is no data available now so need to wait for poll (new return value)
|
|
when a request is
half-finished.
Note the the req struct used to be re-initialized AFTER reading pipeline data, so now that we
initialize it from the caller we must be careful not to overwrite the pipeline data.
Also we now need to handle the case where the buffer is already full when get_request is called -
previously this never happened as it was always called with an empty buffer and looped until done.
Now get_request is called in a loop, so the next step is to run the loop on a socket only when poll
signals it is readable.
|

easier refactoring later.
The next step will be to call the correct function after a poll, rather than looping unconditionally
|
|
complicated and should
be redundant once we poll
|
|
It eliminates noisy events when using inotify and fixes a TOCTOU issue.

Removed APOP and SASL authentication from the POP3 section and metalink
support from the client section as these features were implemented in
this release.
Moved adding gssapi to SASL into it's own section rather than repeat it
for each protocol.

Let's call it 7.27.1 for now, but it it probably going to become 7.28.0
when released.

This needs another look from the configure experts. I tested that
it works so far with MinGW64 cross-compiler; libcurl builds and
links fine, but curl not yet ...

The --silent bug came with 7561a0fc834c435 which was never in a release.

Synced the output to the same short form as we now use for
Windows SSL (WinSSL).

Previously the curl_multi interface would freeze if darwinssl was
enabled and at least one of the handles tried to connect to a Web site
using HTTPS. Removed the "wouldblock" state darwinssl was using because
I figured out a solution for our "would block but in which direction?"
dilemma.
