2009-04-14ep_strbuf: fix some bugs and additional changesBill Meier1-124/+175
-Bugs * str->len not set correctly in some cases; * trailing '\0' not always accounted for; * (issues relating to determining when & how much to expand string buffer). -Other * Change append, append_c, truncate to return pointer to ep_strbuf (similar to the corresponding GString functions); * Rename certain variables to clarify usage (as I understand the intended usage); * ep_strbuf_grow: use current allocated length and not current string length as the starting point; * Optimizations; * Add some additional comments to emem.h ep_strbuf section * Use consistent indentation throughout emem.c; svn path=/trunk/; revision=28044

2008-08-05Add a debug helper for EP memory corruptionLuis Ontanon1-1/+53
if compiled in and the env var WIRESHARK_DEBUG_EP_CANARY is set: will check for canary integrity at every call to EP_CHECK_CANARY() if corruption is found it exits pronting the prior location and the location in which corruption was found. Hopefully it stops running while the corruptor is still in the stack. see EP_CHECK_CANARY() calls in packet.c as an example. svn path=/trunk/; revision=25927

Reads EMEM_CANARY_DATA_SIZE (15) bytes, compares return value to EMEM_CANARY_SIZE (8). Also, I also added setbuf call in patch so it reads 15 bytes instead of 4096 or 8192. svn path=/trunk/; revision=24596

- As noted by Thomas Anders values are not added to the tree anymore. Move the calling of subdissectors to the end of the function, so that the value is added to the tree. - add port 8161 to be decoded as SNMP (hey, it's on IANA's services file!)

2007-05-29Check for G_GINT64_MODIFIER in Wireshark as we do in Wiretap.Guy Harris1-2/+2
In all the places where a cast to "long long" or "unsigned long long" was done, use G_GINT64_MODIFIER and get rid of the cast, as 1) there's no guarantee that "%ll" works and 2) there's no guarantee that "long long" works (the latter definitely does *NOT* work with MSVC++; the former doesn't work with regular printf in MSVC++, but it might work with the GLib printf-based functions). svn path=/trunk/; revision=21978
2007-05-29From David Howells :Sebastien Tandel1-2/+2
Fix compilation failures when building wireshark-0.99.6-SVN-21916 on an x86_64-unknown-linux-gnu target with gcc version 4.1.2 20070403 (Red Hat 4.1.2-8). The failures fall into two categories: (1) Casts between pointers and 32-bit integers without an intermediary cast via 'long' or 'unsigned long'. This results in a compiler warning complaining about casts between a pointer and an integer of a different size. (2) Passing values to "%lld" or similar printf-style format options that the compiler thinks are a different size. Such values need to be cast to 'long long' or 'unsigned long long'. svn path=/trunk/; revision=21975

--enable-extra-gcc-checks set. If we turn on -pedantic, try turning on -Wno-long-long as well, so that it's not *so* pedantic that it rejects the 64-bit integral data types that we explicitly require. Constify a bunch of stuff, and make some other changes, to get rid of warnings. Clean up some indentation. svn path=/trunk/; revision=21526

generalize teh tree management and to use trees with different storage scope without too much code duplication. it would be useful with a tree that had indefinite storage instead of the emem functions which commonly have ep or se storage scope. indefinite storage scope would be useful for example for managing a global and static set of well known guid to name mappings(not yet implemented) and also for oid to name mappings. svn path=/trunk/; revision=18886

2006-06-16From Albert Chin Jaap Keuter1-1/+1
HP-UX doesn't have MAP_ANON but it does have MAP_ANONYMOUS. Moreoever, according to mmap(2) on RHEL: MAP_ANONYMOUS The mapping is not backed by any file; the fd and offset argu- ments are ignored.
