2019-10-18http2_recv: a closed stream trumps pause stateDaniel Stenberg
... and thus should return 0, not EAGAIN. Reported-by: Tom van der Woerdt Fixes #4496 Closes #4505
2019-10-18http2: expire a timeout at end of streamDaniel Stenberg
To make sure that transfer is being dealt with. Streams without Content-Length need a final read to notice the end-of-stream state. Reported-by: Tom van der Woerdt Fixes #4496
2019-10-03http2: move state-init from creation to pre-transferDaniel Stenberg
To make sure that the HTTP/2 state is initialized correctly for duplicated handles. It would otherwise easily generate "spurious" PRIORITY frames to get sent over HTTP/2 connections when duplicated easy handles were used. Reported-by: Daniel Silverstone Fixes #4303 Closes #4442

2019-09-16http2: relax verification of :authority in push promise requestsChristoph M. Becker
If the :authority pseudo header field doesn't contain an explicit port, we assume it is valid for the default port, instead of rejecting the request for all ports. Ref: https://curl.haxx.se/mail/lib-2019-09/0041.html Closes #4365
2019-08-26http2: when marked for closure and wanted to close == OKDaniel Stenberg
It could otherwise return an error even when closed correctly if GOAWAY had been received previously. Reported-by: Tom van der Woerdt Fixes #4267 Closes #4268
2019-08-01timediff: make it 64 bit (if possible) even with 32 bit time_tDaniel Stenberg
... to make it hold microseconds too. Fixes #4165 Closes #4168
2019-07-30cleanup: remove the 'numsocks' argument used in many placesDaniel Stenberg
It was used (intended) to pass in the size of the 'socks' array that is also passed to these functions, but was rarely actually checked/used and the array is defined to a fixed size of MAX_SOCKSPEREASYHANDLE entries that should be used instead. Closes #4169
2019-07-29http2_recv: trigger another read when the last data is returnedDaniel Stenberg
... so that end-of-stream is detected properly. Reported-by: Tom van der Woerdt Fixes #4043 Closes #4160
2019-07-10headers: Remove no longer exported functionsDaniel Gustafsson
There were a leftover few prototypes of Curl_ functions that we used to export but no longer do, this removes those prototypes and cleans up any comments still referring to them. Curl_write32_le(), Curl_strcpy_url(), Curl_strlen_url(), Curl_up_free() Curl_concat_url(), Curl_detach_connnection(), Curl_http_setup_conn() were made static in 05b100aee247bb9bec8e9a1b0166496aa4248d1c. Curl_http_perhapsrewind() made static in 574aecee208f79d391f10d57520b3. For the remainder, I didn't trawl the Git logs hard enough to capture their exact time of deletion, but they were all gone: Curl_splayprint(), Curl_http2_send_request(), Curl_global_host_cache_dtor(), Curl_scan_cache_used(), Curl_hostcache_destroy(), Curl_second_connect(), Curl_http_auth_stage() and Curl_close_connections().

2019-06-24http2: call done_sending on end of uploadDaniel Stenberg
To make sure a HTTP/2 stream registers the end of stream. Bug #4043 made me find this problem but this fix doesn't correct the reported issue. Closes #4068
2019-06-21http2: don't call stream-close on already closed streamsDaniel Stenberg

2019-05-30http2: Stop drain from being permanently set onJosie Huddleston
Various functions called within Curl_http2_done() can have the side-effect of setting the Easy connection into drain mode (by calling drain_this()). However, the last time we unset this for a transfer (by calling drained_transfer()) is at the beginning of Curl_http2_done(). If the Curl_easy is reused for another transfer, it is then stuck in drain mode permanently, which in practice makes it unable to write any data in the new transfer. This fix moves the last call to drained_transfer() to later in Curl_http2_done(), after the functions that could potentially call for a drain. Fixes #3966 Closes #3967 Reported-by: Josie-H
2019-05-16cleanup: remove FIXME and TODO commentsDaniel Stenberg
They serve very little purpose and mostly just add noise. Most of them have been around for a very long time. I read them all before removing or rephrasing them. Ref: #3876 Closes #3883

2019-02-20http2: verify :athority in push promise requestsDaniel Stenberg
RFC 7540 says we should verify that the push is for an "authoritative" server. We make sure of this by only allowing push with an :athority header that matches the host that was asked for in the URL. Fixes #3577 Reported-by: Nicolas Grekas Bug: https://curl.haxx.se/mail/lib-2019-02/0057.html Closes #3581

2019-01-11urldata: rename easy_conn to just connDaniel Stenberg
We use "conn" everywhere to be a pointer to the connection. Introduces two functions that "attaches" and "detaches" the connection to and from the transfer. Going forward, we should favour using "data->conn" (since a transfer always only has a single connection or none at all) to "conn->data" (since a connection can have none, one or many transfers associated with it and updating conn->data to be correct is error prone and a frequent reason for internal issues). Closes #3442
2018-12-20http2: clear pause stream id if it gets closedDaniel Stenberg
Reported-by: Florian Pritz Fixes #3392 Closes #3399
2018-12-08Upon HTTP_1_1_REQUIRED, retry the request with HTTP/1.1Johannes Schindelin
This is a companion patch to cbea2fd2c (NTLM: force the connection to HTTP/1.1, 2018-12-06): with NTLM, we can switch to HTTP/1.1 preemptively. However, with other (Negotiate) authentication it is not clear to this developer whether there is a way to make it work with HTTP/2, so let's try HTTP/2 first and fall back in case we encounter the error HTTP_1_1_REQUIRED. Note: we will still keep the NTLM workaround, as it avoids an extra round trip. Daniel Stenberg helped a lot with this patch, in particular by suggesting to introduce the Curl_h2_http_1_1_error() function. Closes #3349 Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
2018-11-23snprintf: renamed and we now only use msnprintf()Daniel Stenberg
The function does not return the same value as snprintf() normally does, so readers may be mislead into thinking the code works differently than it actually does. A different function name makes this easier to detect. Reported-by: Tomas Hoger Assisted-by: Daniel Gustafsson Fixes #3296 Closes #3297

Closes #3144
2018-10-03memory: ensure to check allocation resultsDaniel Gustafsson
The result of a memory allocation should always be checked, as we may run under memory pressure where even a small allocation can fail. This adds checking and error handling to a few cases where the allocation wasn't checked for success. In the ftp case, the freeing of the path variable is moved ahead of the allocation since there is little point in keeping it around across the strdup, and the separation makes for more readable code. In nwlib, the lock is aslo freed in the error path. Also bumps the copyright years on affected files.
