2017-05-18Add parse_uint function to improve integer overflow handlingdequis
Originally found by oss-fuzz (issue 525) in get_ansi_color using ubsan. After a lot of analysis I'm 99% sure this isn't security relevant so it's fine to handle this publicly. The fix is mainly adding a function that does it right and use it everywhere. This is harder than it seems because the strtol() family of functions doesn't have the friendliest of interfaces. Aside from get_ansi_color(), there were other pieces of code that used the same (out*10+(*in-'0')) pattern, like the parse_size() and parse_time_interval() functions, which are mostly used for settings. Those are interesting cases, since they multiply the parsed number (resulting in more overflows) and they write to a signed integer parameter (which can accidentally make the uints negative without UB) Thanks to Pascal Cuoq for enlightening me about the undefined behavior of parse_size (and, in particular, the implementation-defined behavior of one of the WIP versions of this commit, where something like signed integer overflow happened, but it was legal). Also for writing tis-interpreter, which is better than ubsan to verify these things.

2014-06-30Finish 256 colour support for IrssiAilin Nemui
256 colour patch is cleaned up and the remaining cases are made work, this includes especially Theme support, which was not implemented before. Changes not related to colours were reverted again, making a review of the two patches against master easier to follow. As a byproduct of the Hex-colour code parser, the 24bit colours are also implemented. Actually using them in the terminal is guarded by a compile time switch (as well as a run time switch), as it breaks the existing colour protocol and requires additional storage. To make a seamless usage, down-conversion is provided for 8 and 16 colours. Diverging from Tom's approach, the colour protocol is reverted back to the original one. Unfortunately, the changes required in the Theme engine will break the API. For more details, please refer to the patch documentation at either http://irssi-docs.wikispaces.com/Notes-256-Colour or https://github.com/shabble/irssi-docs/wiki/Notes-256-Colour
2014-06-30Initial implementation of 256 colour support for IrssiTom Feist
This patch implements some 256 colour support for Irssi up from the previous 16 colours. Initial parsing of the %x/%X format codes is implemented and the parser accounts in advances the char* for that. The colour attributes are widened from 4 to 8 bit. The colour protocol is changed to a new format. Some pointers to remaining work are written in the comment in textbuffer.h. Note that Irssi already does support requesting 256 colours from the terminal in the original source code, so this part did not have to be touched.

automatic converter to these settings later. Meanwhile you CVS users can fix your config files yourself :) Time settings allow using "days", "hours", "minutes", "seconds" and "milliseconds" or several of their abbreviations. For example "5d 4h 5msecs". Size settings allow using "gbytes", "mbytes", "kbytes" and "bytes" or their abbrevations. For example "5MB".
