Junio C Hamano 0 siblings, 2 replies; 5+ messages in thread From: Sven Strickroth @ 2021-10-22 16:13 UTC (permalink / raw) To: git, Junio C Hamano, Johannes Schindelin Hi, Git differentiates between different variants of SSH tools. One variant is the tortoiseplink variant. When this is configured Git passes passes a special "--batch" parameter and passes the port using "-P" (capitalized P) t the SSH tool. IIRC tortoiseplink was initially created by TortoiseCVS which is nowadays not maintained any more (<http://www.tortoisecvs.org/download.shtml>). In TortoiseSVN and TortoiseGit tortoiseplink was modified six years ago (around 2015-03-07) to ignore the "--batch" parameter and also accept "-p" additionally to "-P" (cf. <https://osdn.net/projects/tortoisesvn/scm/svn/commits/26348>). Therefore, my first question: Does Git still want to support very old versions of tortoiseplink or should I provide a patch which drops support for it? Second question: TortoiseGit comes with an even more improved version of TortoisePLink (named TortoiseGitPLink, but also ships the same binary as tortoiseplink) that also accepts "-o SetEnv=..." parameters in order to support the Git protocol version 2. At the moment TortoiseGit automatically sets the environment variable "GIT_SSH_VARIANT=ssh". This works, but is not perfect if other parameter of OpenSSH are used. Would it make sense to add a new ssh variant tortoisegitplink? If yes, how to handle new versions that might also support even more OpenSSH command line parameters? -- Best regards, Sven Strickroth PGP key id F5A9D4C4 @ any key-server ^ permalink raw reply [flat|nested] 5+ messages in thread

The answer is it depends, in some cases we support >10 year old software because it's in wide use, so some sort of vague estimate of how much this is likely to impact users would be helpful, i.e. are users who are using a modern git likely to have a modern version of the software as well, or do they mix & match? ^ permalink raw reply [flat|nested] 5+ messages in thread

You sent the question to me so I am answering, but this depends on (1) who the users who use TortoisePlink are and (2) by dropping support for it, what we would gain. I am guessing that nobody other than those on Windows use TortoisePlink, and that everybody other than those who build their own Git from source use Dscho's Git-for-Windows, and I further assume that the GfW comes with its own copy of OpenSSH. So our intended audience is those who started using Git on Windows back when TortoisePlink was still a thing, are still happily using TortoisePlink, and are willing to only update Git but not migrate to OpenSSH. How big that audience is, I do not know, as I do not do Windows. How much maintenance burden is the "support" costing us? A quick scan in connect.c tells me that the "add --batch to the command line" would be the only thing we would be able to shed; everything else seems to be shared with plink and putty. So...? ^ permalink raw reply [flat|nested] 5+ messages in thread

How big that audience is, I do not know, as I do not do > Windows. Nobody really knows, but we started discouraging `plink` usage (also `tortoiseplink` usage) already way back in the msysGit days. AFAIR we simply ran into too much trouble, and started to only offer `plink` as an option if the user had _any_ PuTTY saved sessions. > How much maintenance burden is the "support" costing us?

Since I have to assume a very small usership, I would think that we can drop support for the older `tortoiseplink`. But you're right, what does it _buy_ us? My guess is that Sven wants to go further and enable the `-o SetEnv` thing for protocol v2 (which we figured out together, over in the Git for Windows bug tracker, to be turned off when pushing). But that would require the `tortoisegitplink` variant, I think. So maybe a better idea would be to focus on introducing support for `tortoisegitplink` and work on the `-o SetEnv` issue, and leave the `--batch` code alone for now.
