Daniel Stenberg 169b2eeb94 Fixes bug #669059. We now extract the Content-Type better and more accurate. 2003-01-30 05:04:02 +00:00
Daniel Stenberg 30a46e1135 John McGowan found a problem where the DEBUGFUNCTION was called with bad 
data on uploads.
 2003-01-29 12:52:45 +00:00
Daniel Stenberg a7c72b7abf removed the local variables for emacs and vim, use the new sample.emacs 
way for emacs, and vim users should provide a similar non-polluting style
 2003-01-29 10:14:20 +00:00
Daniel Stenberg 2b054e5309 Bertrand Demiddelaer found and fixed this memory leak. 2003-01-24 11:13:59 +00:00
Daniel Stenberg dee3163d95 when a chunked error is noticed, store the error number in the error string 
to enable better error-tracking
 2003-01-21 16:03:38 +00:00
Daniel Stenberg 5a83976c99 Markus F.X.J. Oberhumer's patch that reduces memory usage quite a bit by 
only allocating the scratch memory buffer once it is needed and not always
in the handle.
 2003-01-20 12:52:34 +00:00
Daniel Stenberg f26a338a54 copyright year update in the source header 2003-01-16 21:08:12 +00:00

Daniel Stenberg ec24efda74 Simon Liu's HTTP200ALIASES-patch! 2003-01-07 16:15:53 +00:00
Daniel Stenberg efbe930a69 CURLE_HTTP_NOT_FOUND => CURLE_HTTP_RETURNED_ERROR 2002-12-18 16:51:02 +00:00
Daniel Stenberg db6ff224f8 The initial HTTP request can now be sent in multiple parts, as part of the 
regular transfer process. This required some new tweaks, like for example
we need to be able to tell the tranfer loop to not chunky-encode uploads
while we're transferring the rest of the request...
 2002-12-10 13:10:00 +00:00
Daniel Stenberg 4bcc866c52 The fread() callback pointer and associated pointer is now stored in the 
connectdata struct instead, and is no longer modified within the 'set' struct
as previously (which was a really BAAAD thing).
 2002-12-09 15:37:54 +00:00
Daniel Stenberg f6cdb820af read and write as much as possible until end of data or EWOULDBLOCK before 
returning back to the select() loop. Consider this a test so far.
 2002-12-05 14:26:30 +00:00
Daniel Stenberg 1c49a00d64 compareheader() was moved over to http.c and got a Curl_ prefix 
The chunked transfer upload never stopped due to a silly add before we checked
for >0!
 2002-11-28 15:46:22 +00:00
Daniel Stenberg 42acb00c81 moved the bools in the connectdata struct into the substruct named 
ConnectBits where the other bools already are
 2002-11-11 23:03:03 +00:00
Daniel Stenberg 03c22b4576 Now supports "Transfer-Encoding: chunked" for HTTP PUT operations where the 
size of the uploaded file is unknown.
 2002-11-11 08:40:37 +00:00
Daniel Stenberg cdba92ac3c when using checkprefix(), the first argument must be the prefix! 2002-10-28 22:19:23 +00:00
Daniel Stenberg 6d28f92ffe Transfer-Encoding: needs 17 bytes passed, not 18 2002-10-28 21:52:27 +00:00
Daniel Stenberg 01387f42c5 kromJx@crosswinds.net's fix that now uses checkprefix() instead of 
strnequal() when the third argument was strlen(first argument) anyway.
This makes it less prone to errors. (Slightly edited by me)
 2002-10-28 21:52:00 +00:00
Daniel Stenberg b5a74715cf bad headers can come in two kinds, we either treat everything as one big 
badly assumed header, or we think that parts of the buffer is a bad header
and the rest is treated as a normal body part
 2002-10-23 13:48:37 +00:00
Daniel Stenberg 0fa512f26d Nikita Schmidt's fix to debian bug report #165382. This is verified with 
the new test case 55.
 2002-10-21 12:07:02 +00:00
Daniel Stenberg 9e612b5550 make very sure that we return 'done' properly when a transfer is done, as 
otherwise the multi interface gets problems
 2002-10-18 15:28:33 +00:00
Daniel Stenberg 45bd009bb1 if we found no string on the Location: line, don't try to follow it 2002-10-18 13:51:00 +00:00
Daniel Stenberg 156aad198f Make the COOKIESESSION work better by creating a list of cookie files files 
when given in the curl_easy_setopt() and then parse them all on the first
curl_easy_perform() call instead.
 2002-10-17 07:10:39 +00:00
Daniel Stenberg 265c58611f When we receive a "bad header" we must sure not to write down the data part 
as well, as then we write the same data twice.
 2002-10-11 20:55:08 +00:00
Daniel Stenberg c3cc616264 Junk data could get inserted when saving/getting HTTP headers, as discovered 
by Craig Davison. Now we deal with the 'nread' variable correctly between
each header line.
 2002-10-09 13:03:51 +00:00
Daniel Stenberg 5f649a1649 Move the URL concat code to Curl_follow(), and added a proto for that 
function. For Location: following.
 2002-10-07 13:38:34 +00:00
Daniel Stenberg 3d5820648b as Ralph Mitchell pointed out, the Location: following code needs some 
basic ./ and ../ strip-off understanding, and this change introduces with.
test cases 49 - 52 test this.
 2002-10-04 14:15:01 +00:00
Daniel Stenberg 5b3069e265 spell fix comment 2002-09-23 12:55:36 +00:00

headers at all
 2002-09-16 14:02:08 +00:00
Daniel Stenberg c19844a0a3 better deal with HTTP(S) servers that respond with no headers at all, test 
case 306 added to verify that we do right
 2002-09-13 12:40:36 +00:00

Daniel Stenberg 7313501e30 fixed the Curl_cookie_add() invoke to not assume a space after the colon 2002-07-29 22:23:55 +00:00
Daniel Stenberg e54e0c7877 CURLOPT_BUFFERSIZE allows an application to set a prefered buffer size 
for receiving data from the network. It is meant as a hint, not as a forced
limit.
 2002-06-15 21:00:54 +00:00
Daniel Stenberg 407583e8e2 Moved the secondarysocket cleanup. The 'conn' struct may have been cleared 
already at that other place.
 2002-06-12 22:04:25 +00:00
Daniel Stenberg d866716565 Gautam Mani found a socket descriptor leak that happened when FTP transfers 
failed and you reinvoked curl_easy_perform().
 2002-06-10 12:34:04 +00:00
Daniel Stenberg 99c0456872 Adjusted to make curl_multi_perform() work properly even when

 2002-05-28 14:18:36 +00:00
Daniel Stenberg 44debdde62 Better support for being used with the multi interface without the *fd_set() 
and proper select()ing have been made.

Daniel Stenberg 86cc34c0de made the DEBUGFUNCTION get called properly on a few more places, especially 
for DATA_IN and DATA_OUT.
 2002-05-03 12:07:32 +00:00
Daniel Stenberg 913e997061 use and set the fd_set pointers instead of the actual values, as then we 
work properly with the multi interface when the user has provided the
fd_sets!
 2002-05-02 22:14:31 +00:00
Daniel Stenberg 35d04c5398 Hanno Kranzhoff noticed we didn't properly reset the download/upload counters 
before transfers, when doing multiple ones on the same handle.
 2002-05-02 08:52:09 +00:00
Daniel Stenberg 08f8917acb Dirk Manske's fix for HTTP response code 301, that now behaves more like

an error, even if we were decoding a chunked-encoded transfer
 2002-03-15 12:42:41 +00:00
Daniel Stenberg cfdb6f851c 2002 2002-03-14 14:37:41 +00:00

new internal "order".
 2002-01-25 08:35:49 +00:00

Daniel Stenberg ca0fd33d2d Georg Horn's STARTTRANSFER_TIME patch 2001-11-20 15:00:50 +00:00
Daniel Stenberg fe3a78ab19 we use signal() to ignore signals only as long as we have to, and we now 
restore the previous (if any) signal handler properly on return.
 2001-11-07 14:13:29 +00:00
Daniel Stenberg 2e32d415c0 myalarm() is history, we now use HAVE_ALARM and we now do our very best to 
1 - restore the previous sigaction struct as soon as we are about to shut
off our timeout
2 - restore the previous alarm() timeout, in case an application or similar
had it running before we "borrowed" it for a while.

No, this does not fix the multi-thread problem you get with alarm(). This
patch should correct bug report #478780:
//sourceforge.net/tracker/?func=detail&atid=100976&aid=478780&group_id=976

If not, please post details!
 2001-11-06 19:33:13 +00:00

Daniel Stenberg db0e3cc60c call Curl_done() in Curl_perform() after Transfer() was called, even it it

 2001-09-28 11:04:43 +00:00
