Hi Peter, Martin, and others, Thanks for your replies. - The bugs apply to all systems that use GNU Readline, not just Linux or Arch Linux. - Readline version 6.3 changed the signal handling so that SIGWINCH is no longer handled automatically by the library. This means it's not currently possible for people using R on e.g. Linux to resize the terminal, or at least when they do so they have to make sure that all their commands fit in one line and don't wrap. - There is also a long-standing bug in Readline where the callback interface didn't properly clear the line on SIGINT (^C). This means that "exiting" reverse-incremental-search with ^C would give an apparently empty prompt which still had some pending input, so if you hit ^C-Return then an unintended command would get executed. If they're not "bothering all that many people", then perhaps it's because everyone uses Windows or Mac OS X or RStudio. For me these are pretty significant bugs. The second one causes unintended code to be executed. Random code could delete files, for example, or worse. The first one bites me every time I want to change the size of a window, which is pretty often. I tried to get Readline maintainer Chet Ramey to fix these on the Readline side, but he disagreed with my proposal: https://lists.gnu.org/archive/html/bug-readline/2016-04/threads.html I'm glad that my message here at least was seen and I hope that someone who uses the R command line on Linux will have time to verify that the patches work correctly. They are basically Chet-approved workarounds for bugs/changes in Readline, not very complicated. Do either of you know a Linux R person you could ping to get these patches checked out? I'm not overly frustrated, and I'm not in a major hurry, but from what we've observed it seems like waiting for someone concerned to come along and finally read Bugzilla or the R-Devel archives is not going to result in a very dense Poisson process...

Dear Frederik, I can confirm that especially the first issue on your list (resizing the terminal) has "bothered me" badly for some time now: I'm on Ubuntu (usually).

Actually, I think both Martin and I use reaadline R versions on a daily basis (Linux and OSX Terminal respectively). For my case, it is just that I rarely use the backwards search feature and I'm old enough that terminal widths other than 80 look odd to me so I don't resize much either. Of course that doesn't mean that the bugs aren't annoying to others! -pd On 13 May 2016, at 00:23 , frederik at ofb.net wrote:> Hi Peter, Martin, and others, > > Thanks for your replies. > > - The bugs apply to all systems that use GNU Readline, not just Linux > or Arch Linux. > > - Readline version 6.3 changed the signal handling so that SIGWINCH is > no longer handled automatically by the library.

I'm pretty sure (but may be wrong) that 99% of useRs do not work much with R in a readline-enabled console, but rather via another interface. Maybe only 95% if you restrict yourself to non-Mac, non-Windows (i.e. typically Linux) users. > For me these are pretty significant bugs.

Well, many of us from R core use Linux regularly or at least occasionally and hence can take time to confirm the bug ... and if the patch seems to fix it. However, most of experienced R users, not just R core, "believes" in reproducibility and hence we want to work with *.R scripts (or *.Rmd etc nowadays): We had a saying in the ESS manuals for 20 years or so: "The source code is real." which had later been extended to "The source code is real. The objects are realizations of the source code." As a consequence, we do not "work" in the R console; we may tinker a bit for experiments, but we really work "in" the R source files. For that reason, if apply your patches and quickly check that the previous bug seems gone, I would not notice if the patch had introduced new bugs ... just because I almost never work in "readline-R" but always (99.9%) work in Linux.

Dear R Devel, Sorry for sending so many emails, but I haven't heard that anyone is working on the patches I created. A few weeks ago I wanted to do something to contribute to R because I use it a lot. I picked the most annoying bugs I could find, and created two of the simplest patches I could create, but all I've had in response from the R core team (aside from briefly banning my Bugzilla account) is a lengthy explanation for why power users don't use the basic command line interface. I'm grateful to Peter for the list of tools like ESS that people use to interface with R; but if I wanted to submit a bug to ESS then I would have sent it to a different mailing list. Thank you G?ran for confirming that you experience these bugs. I've Cc'ed two other users, Chris Smowton and "Terran", who commented on the Bugzilla bugs. Do you guys want to weigh in on the relative importance of getting these fixed? Nobody asked me to describe the patches in more detail, but I'll give a brief summary in case it helps: One of my patches adds a signal handler for SIGWINCH (which GNU Readline stopped handling a few years ago without telling anyone). There is no other use of SIGWINCH in the R code so I don't think this will cause problems. This makes terminal-resizing possible. The other one adds some additional cleanup to popReadline. Now, popReadline is called every time a command is entered at the prompt, or when R catches SIGINT, to reset the terminal settings and take control back from Readline. My second patch fixes incremental-search by amending popReadline to clear the line state as well. I invite creative suggestions as to how these might lead to unforeseen trouble for Unix or non-Unix users - what I might have missed in my testing, etc. Otherwise, I would appreciate some kind of real input as to what I should do or who I should contact to get this rolling. We're all short on time; if we can get this taken care of quickly and efficiently then we'll have more time left for other stuff.

Agreed regarding read line-- absent mindedly using C-c to exit a search and then accidentally running garbage because the prompt looks blank but isn't continues to be a problem. On 17 May 2016 2:41 a.m., <frederik at ofb.net> wrote: Dear R Devel, Sorry for sending so many emails, but I haven't heard that anyone is working on the patches I created. A few weeks ago I wanted to do something to contribute to R because I use it a lot. I picked the most annoying bugs I could find, and created two of the simplest patches I could create, but all I've had in response from the R core team (aside from briefly banning my Bugzilla account) is a lengthy explanation for why power users don't use the basic command line interface. I'm grateful to Peter for the list of tools like ESS that people use to interface with R; but if I wanted to submit a bug to ESS then I would have sent it to a different mailing list. Thank you G?ran for confirming that you experience these bugs. I've Cc'ed two other users, Chris Smowton and "Terran", who commented on the Bugzilla bugs. Do you guys want to weigh in on the relative importance of getting these fixed? Nobody asked me to describe the patches in more detail, but I'll give a brief summary in case it helps: One of my patches adds a signal handler for SIGWINCH (which GNU Readline stopped handling a few years ago without telling anyone). There is no other use of SIGWINCH in the R code so I don't think this will cause problems. This makes terminal-resizing possible. The other one adds some additional cleanup to popReadline. Now, popReadline is called every time a command is entered at the prompt, or when R catches SIGINT, to reset the terminal settings and take control back from Readline. My second patch fixes incremental-search by amending popReadline to clear the line state as well. I invite creative suggestions as to how these might lead to unforeseen trouble for Unix or non-Unix users - what I might have missed in my testing, etc. Otherwise, I would appreciate some kind of real input as to what I should do or who I should contact to get this rolling. We're all short on time; if we can get this taken care of quickly and efficiently then we'll have more time left for other stuff.
