C/C++ refactoring support

EDIT: updated on 2016-02-06 (fixed links, added QtCreator)

The people I've discussed refactoring with usually got pretty enthusiastic about it when showing them what can be done in properly designed languages like Java, Erlang or Haskell. They asked whether these kind of things were doable for weaker programming languages like C and C++ by free open source tools.

I don't have much experience in this topic, as I haven't done bigger projects in this language yet, and the small ones I did were usually properly designed for the purpose from the start.

So I looked around for possible solutions, and doing a few web searches yielded the following links. I may try some of these in the future just for curiosity.

Be warned that not all listed features are available or complete. If you have experience with any of these, or with any refactoring tool for that matter, please let us hear your voice in the comments. (Maybe it would be worthwhile to open a wiki about available refactoring tools for each language)

Tftp secret of TL-WR740N uncovered

I've found out that even this particular entry level router supports anti-bricking, so there's no need for soldering, unless of course you are modding. The method I used is the following: Set up a tftp server  on your PC and verify if it works correctly (configuration, permissions, firewalls, etc.) Rename your target firmware to wr740v4_tp_recovery.bin and copy it to your base folder (by default /tftpboot). I tested with openwrt-ar71xx-generic-tl-wr740n-v4-squashfs-factory.bin r43602. Set up the following static IP for your PC: 192.168.0.66 /255.255.255.0. If you're not sure about the firmware name on a different model, start a packet sniffer on your PC ( tcpdump -i eth0 -n -l ) and look for the name in the RRQ message. Preferably disconnect WAN from the router Connect the PC to a LAN port Power off the router Press and hold the reset button Power on the router After the leftmost (power) LED and the rightmost (padlock) LED turn on alone in a few seconds, release

Hidden TFTP of TP-Link routers

I did some more investigation after the positive results with the TL-WR740Nv4  (click the link to get introduced to the way of recovery). Most users report that devices and firmware updates released after a point in time usually have this mode enabled. If a firmware update is available from the vendor for your device, it's a good idea to apply that update before installing OpenWRT or dd-wrt UNLESS you own something for which upgrading will ensure incompatible with OpenWrt, like a TL-WR730N , and possible some other models (please report). Note that some old models have newer updates in different languages, those may also be worth a try ( TODO : compatibility?). Also remember that later on, tftp recovery will need a type of firmware image without a boot loader, so strip it with dd if yours has it ( grep U-Boot , or check the filename). Positive reported claims so far (personal results highlighted): TL-WDR4300 router 192.168.0.86 server 192.168.0.66 query wdr4300v1_tp_recovery.b
