History of Changes
Daniel (22 November 2001)
- Andrés García helped me out to track down the roots of bug report #479537,
which was concerning curl returning the wrong error code when failing to
connect. This didn't happen on all systems, and more specificly I've so far
only seen this happen on IPv4-only Linux hosts.
- I applied the fixes for the two bugs Eric Lavigne found when doing his MacOS
port. A missing comma in arpa_telnet.h and a pretty wild write in the FTP
response reader function. The latter write is however likely to occur in our
own buffer unless very big FTP server replies (>25K) are read. I've never
seen such a reply ever, so I think this is a relatively minor risk.
Daniel (21 November 2001)
- Moonesamy provided code to prevent junk from being output when libcurl
returns an error code but no error description and that corrects how make is
run in the Makefile.dist file (that appears as root Makefile in release
archives).
- Eric Lavigne mailed me bugfixes and patches for building libcurl on MacOS
(non-X). He'll get back with more updated patches soon.
- Kevin Roth modified the cygwin files once again, now to build against the
shared OpenSSL DLLs.
Version 7.9.2-pre4
Daniel (20 November 2001)
- Georg Horn brought a patch that introduced CURLINFO_STARTTRANSFER_TIME,
complete with man page updates!
- Miklos Nemeth provided details enough to update the Borland makefile
properly.
- Lars M Gustafsson found a case with a bad free(). In fact, it was so bad I'm
amazed we never saw this before!
- Kevin Roth patched the cygwin Makfile.
Daniel (16 November 2001)
- Klevtsov Vadim fixed a bug in how time-conditionals were sent when doing
HTTP.
Version 7.9.2-pre3
Daniel (14 November 2001)
- Samuel Listopad patched away the problem with SSL we got when someone call
curl_global_init() => curl_global_cleanup() => curl_global_init(). The
second init would not "take" and SSL would be unusable with curl from that
point. This doesn't change the fact that calling the functions that way is
wrong. curl_global_init() should be called exactly once and not more.
Daniel (13 November 2001)
- Fixed some minor variable type mixups in ftp.c that caused compiler warnings
on HP-UX 11.00.
- The FTP fix I did yesterday used an uninitialized variable that caused
spurious errors when doing FTP.
Version 7.9.2-pre2
- Ricardo Cadime fell over a multiple-requests problem when first a FTP
directory fetch failed and then a second request is made after that. The
second request happened to get the FTP server response back from the
previous request, when it did its initial CWD command.
- Bjorn Reese pointed out that we could improve the time diff function to
- Kai-Uwe Rommel made me aware that -p (http proxy tunnel) silly enough didn't
work for plain HTTP requests! So I made that work.
Version 7.9.2-pre1
Daniel (12 November 2001)
- Rewrote the Curl_ConnectHTTPProxyTunnel(). It should now not only work a lot
faster, it should also support such ("broken") proxies that John Lask
previously have reported problems with. His proxy sends a trailing zero byte
after the end of the (proxy-) headers. I've tested this myself and it seems
to work on a proxy the previous version also worked with...! This rewrite is
due to the problems John Lask previously experienced.
- Andrés García found out why the "current speed" meter sometimes showed 2048K
for very quick transfers. It turned out the "time diff"-function returned a
zero millisecond diff. We now always say it is at least one millisecond! In
reality, these timers very rarely have that good resolution so even though
the time diff was longer than 1 millisecond, it was reported as no diff.
- I also modified the getinfo() again when returning times, as Paul Harrington
reports that 7.9.1 only returns times with 1 second accuracy, which indeed
is wrong.
Daniel (8 November 2001)
- Marcus Webster found out that curl_formadd() could read one byte outside a
buffer boundary, which then of course could lead to a crash. Marcus also
gracefully provided a patch for this this.
- Glen Scott ran configure on his Cobalt Qube and it didn't figure out the
correct way of calling gethostbyname_r() and thus failed to resolve hosts.
This is two errors: it shouldn't continue the configure script if it finds
gethostbyname_r() but can't figure out how to use it, and it should really
figure out how to use it as it was running Linux and we know how that
works...
Daniel (7 November 2001)
- docs/VERSIONS is a new file in the archive that explains the version number
system we use in the curl project.
- Did some more fixes that now makes libcurl only ignore signals as long as
it needs to, and then restore (if any) previous signal handler again.

committed
Daniel (6 November 2001)
- Enrik Berkhan posted bug report #478780, in which he very correctly pointed
out two bad timeout matters in libcurl: we didn't restore the sigaction
struct (the alarm handler for SIGALRM) nor did we restore the previous
alarm() timeout that could've been set by a "parent" process or similar.

committed
- Kevin Roth made the cygwin binary get stripped before install.
Daniel (5 November 2001)
- Detlef Schmier reported that curl didn't compile using Solaris 8 with the
native cc compiler. It was due to a bad function prototype. Fixed now.
Unfortunately, I can't enable the -Wstrict-prototypes in my debug builds
though, as gcc then complains like crazy on OpenSSL include files... :-(
- John Lask provided SSL over HTTP proxy fixes. They'll need some tweaking
to work on all platforms.
Daniel Stenberg
committed
- John Lask added the -1/--TLSv1 options that forces SSL into using TLS
version 1 when speaking HTTPS.
- John Lask brought a brand new VC++ makefile for the lib directory, that
works a lot better than the previous!
- Ramana Mokkapati brought some clever insights on the LDAP failures (bug
report #475407), and his suggested changes are now applied.
Version 7.9.1
Daniel (4 November 2001)
- I've added a number of new test cases the last few days. A few of them since
I got reports that hinted on problems on timeouts, so I added four tests
with timeouts for all sorts of protocols and stuff. I also came to think of
a few other error scenarios that we currently didn't test properly, so I
wrote up tests for a few of those too.
Daniel (2 November 2001)
- Replaced read() and write() with recv() and send() for socket operations
even under normal unixes.
Daniel (1 November 2001)
- When an FTP transfer was aborted due to a timeout, it wasn't really aware of
how many bytes that had been transferred and the error text always said 0
bytes. I modified this to output the actually transferred amount! :-)
- The FTP fixes in pre7 didn't compile on IPv6 enabled hosts. Does now. I also
added more comments in the lib/ftp.c source file.
- Minor updates to the FAQ, added a brand new section to the web site about
the name issue (who owns "curl"? will someone sue us? etc etc):

- The curl_easy_getinfo() timers accidentally lost their subsecond accuracy as
the calculations used longs instead of doubles! Paul Harrington reported.
- The SSL SocketIsDead() checks weren't good enough (as expected really), so I
had to add a generic internal try-it-out system. If the request on a re-used
connection seems to fail, then we go back and get a new (fresh) connection
and re-tries the request on that instead. It kind of makes the
SocketIsDead() check obsolete, but I think it is a quicker way for those
cases where it actually discovers that the connection is dead.
- When fixing the above, I noticed that we did quite a few writes to sockets
in libcurl where we didn't check the return code (that it actually worked to
send the data). With the new "attempted request" system we must detect those
situations so I went over a bunch of functions, changed return types and
added checks for what they actually return.
Version 7.9.1-pre6
Daniel (31 October 2001)
- Paul Harrington detected a problem with persistant SSL connections. Or to be
more exact, we didn't properly detect that the connection was dead and then
a second connection would try to re-use it wrongly. The solution to this
problem is still not very clear and I'm working on it. One OpenSSL insider
said there is no way to know if the SSL connection is alive or not without
actually trying an operation.
