https://gitea.privatedns.org/xavi/libweb/atom?h=decode-url2023-10-10T22:07:13+00:00Rename project from slweb to libweb2023-10-10T22:07:13+00:00Xavier Del Campo Romeroxavi.dcr@tutanota.com2023-10-10T21:21:35+00:00urn:sha1:0222b75e8554796548e079aa3393c512ae30ac24
It was found out there was another project of the same name around
(https://git.sr.ht/~strahinja/slweb/), also related to website
generation.
In order to avoid confusion, a new name has been chosen for this
project. Surprisingly, libweb was not in use by any distributions
(according to https://repology.org and AUR index), and it should
reflect well the intention behind this project i.e., being a library
to build web-related stuff.
server.c: Replace sequential calls with loop2023-10-10T21:16:11+00:00Xavier Del Campo Romeroxavi.dcr@tutanota.com2023-10-10T21:16:11+00:00urn:sha1:832e198f8c77970b5b923eb18201ba83d9c72b80server.c: Fix build on FreeBSD2023-09-26T20:58:11+00:00Xavier Del Campo Romeroxavi.dcr@tutanota.com2023-09-26T20:58:11+00:00urn:sha1:8b39bc5db98c252269fe526a8c411bf245770ba2Move header files to subdirectory2023-07-20T23:28:38+00:00Xavier Del Campo Romeroxavi.dcr@tutanota.com2023-07-20T21:47:33+00:00urn:sha1:8c3ba33ced08b211db0cd5f81675bdf62f55acc7
Since slweb is meant as a library, it is advisable to keep public header
files under their own directory in order to avoid name clashing i.e.,
#include "something.h"
Now becomes:
#include "slweb/something.h"
server.c: Fix typo2023-07-20T21:52:55+00:00Xavier Del Campo Romeroxavi.dcr@tutanota.com2023-07-05T22:42:12+00:00urn:sha1:01cebe5917c6f3cdca0e13f7b681bb0d6867bb75server.c: Fix undefined behaviour on >1 clients2023-07-20T21:52:55+00:00Xavier Del Campo Romeroxavi.dcr@tutanota.com2023-07-03T11:36:46+00:00urn:sha1:a527164cb5b06055c7696eb4247f8cebee6cf23d
server.c kept an array of all of its active clients, calling realloc(3)
everytime its size had to be modified. However, reallocating this array
had the undesired consequence of moving other active clients to other
memory locations.
Potentially, this would result in dangling pointers from other
components that also kept pointers to struct server_client instances
e.g.: handler.c.
For this reason, the array-based approach has been completely dropped,
in favour of a doubly-linked list.
Avoid crashing on SIGPIPE2023-07-20T21:52:54+00:00Xavier Del Campo Romeroxavi.dcr@tutanota.com2023-05-01T01:06:34+00:00urn:sha1:f75ff13b31d546b4bceea07ce0008bf0fc5ecf71
Under some circumstances, clients could cause SIGPIPE to slcl. Since
this signal was not handled by server.c (i.e., via sigaction(3)), slcl
would crash without any error messages printed to stderr.
In such situation, SIGPIPE should not be usually considered a fatal
error, so it is preferrable to close the connection and keep working.
Replace select(2) with poll(2)2023-07-20T21:52:53+00:00Xavier Del Campo Romeroxavi.dcr@tutanota.com2023-04-27T22:19:32+00:00urn:sha1:2e8485d687dd5f673b8d2aadb0816571d3f32cb7
select(2) has a number of well-known issues (e.g.: FD_SETSIZE limiting
the maximum amount of file descriptors to watch) that are mostly solved
by poll(2) and thus can be used as a drop-in replacement.
Define _POSIX_C_SOURCE2023-07-20T21:52:53+00:00Xavier Del Campo Romeroxavi.dcr@tutanota.com2023-03-24T01:47:11+00:00urn:sha1:af16aa6702ffb385a36504a459210e94704bbe2b
This allows using the default compiler defined by make(1) (i.e.,
c99(1)), thus improving POSIX compatibility.
