* Wrap everything in struct connection, and enforce timeouts everywhereDag-Erling Smørgrav2002-06-051-33/+52
| | | | | | | | (except for DNS operations). Always use funopen() for HTTP, to support both timeouts and SSL. Notes: svn path=/head/; revision=97866

* First step towards SSL support: wrap connections in a 'struct connection'Dag-Erling Smørgrav2002-06-051-77/+84
| | | | | | | | | | | | | which contains the socket descriptor, the input buffer and (yet unused) SSL state variables. This has the neat side effect of greatly improving reentrance (though we're not *quite* there yet) and opening the door to HTTP connection caching. This commit is inspired by email conversations with and patches from Henry Whincup <henry@techiebod.com> last fall. Notes: svn path=/head/; revision=97856
* Do not use __progname directly (except in [gs]etprogname(3)).Mark Murray2002-03-291-3/+1
| | | | | | | | | Also, make an internal _getprogname() that is used only inside libc. For libc, getprogname(3) is a weak symbol in case a function of the same name is defined in userland. Notes: svn path=/head/; revision=93399

* Rework proxy handling so that proxies can be specified as URLs.Dag-Erling Smørgrav2000-10-121-132/+65
| | | | | | | As a side effect, remove a lot of duplicate and now redundant code. Notes: svn path=/head/; revision=67043

| | | | | | | | Work around YA Apache bug: don't send port in Host: header if it's the default port. Notes: svn path=/head/; revision=63842
* Ignore environment variables that are set but empty.Dag-Erling Smørgrav2000-07-211-40/+81
| | | | | | | | | | | | | | | Sort out the size / length confusion. Always try to report the *real* file size in the url_stat structure, no matter how much of it is actually being sent, and try to detect inconsistencies between sizes. Rearrange the request loop to avoid having to add meaningless code just to silence compiler warnings. Switch to a more sensible and consistent interface for the _http_parse*() functions. Notes: svn path=/head/; revision=63716
* Don't try to skip to the requested offset if the server returns more dataDag-Erling Smørgrav2000-07-191-8/+10
| | | | | | | | | than requested. Instead, inform the caller of the real offset by modifying the offset field in the original struct url, and let him decide how to handle the situation. Notes: svn path=/head/; revision=63567
* Introduce fetchXGet*(), which combine the functionalities of fetchGet*() andDag-Erling Smørgrav2000-07-171-7/+21
| | | | | | | | | fetchStat*(). In most cases, either fetchGet*() or fetchXGet*() is a wrapper around the other; in all cases, calling fetchGet*() is identical to calling fetchXGet*() with the second argument set to NULL. Notes: svn path=/head/; revision=63340
* Don't forget to set file descriptor to -1 after closing it, since the codeDag-Erling Smørgrav2000-07-171-1/+1
| | | | | | | | | | outside the loop inspects it to determine whether or not we succeeded in retrieving the requested document. This fixes a bug where fetchGetHTTP() would return a FILE with an invalid file descriptor if it hit the redirect limit without locating the requested document. Notes: svn path=/head/; revision=63337

* Extensive rewrite of the HTTP code. The new code is significantly cleaner andDag-Erling Smørgrav2000-07-121-446/+685
