On one box, some stg locks up after some (not all) commands are used. Everything I have tried works fine, but I have to hit ^c to continue working. It appears the lockup happens while waiting for a subprocess to exit, but I'm not equipped to efficiently debug this on my own. A different box with similar setup which does not show the same issue. I have attempted to twidde the differing use flags on dev-vcs/git and I have attempted to downgrade git and stgit to the latest stable versions to no improvement. Commands that cause lockup: uncommit, push, pop, edit, new, sink, float, undo, redo, show, log, files, export Commands that do not cause lockup: help, series, status, next eroen@falcon ~ $ mkdir stg-test eroen@falcon ~ $ cd stg-test/ eroen@falcon ~/stg-test $ echo test > testfile eroen@falcon ~/stg-test $ git init Initialized empty Git repository in /home/eroen/stg-test/.git/ eroen@falcon ~/stg-test $ git add testfile eroen@falcon ~/stg-test $ git commit -m 'initial' [master (root-commit) 8e12e03] initial 1 file changed, 1 insertion(+) create mode 100644 testfile eroen@falcon ~/stg-test $ echo test2 > testfile eroen@falcon ~/stg-test $ git commit -m 'initial' -a [master 321d3a0] initial 1 file changed, 1 insertion(+), 1 deletion(-) eroen@falcon ~/stg-test $ stg init eroen@falcon ~/stg-test $ stg uncommit Uncommitting 1 patches ...

Something tells me, that might be a bug in git. Could you run FEATURES=test emerge -1av git ... perhaps on both your machines and see whether they yield the same result?
box with no problems: fixed 0 success 9611 failed 0 broken 87 total 10012 (nls and perl use flags disabled) box with hanging stg: fixed 0 success 10092 failed 0 broken 87 total 10306 An unrelated, but way more useful piece of information showed up during this test, as I was conducting it through ssh from the box with working stgit using a different terminal emulator. The hangs only seem to happen when using Konsole. No hangs were observed with xterm, uxterm, lxterminal, xfce4-terminal or yakuake (all of the tested terminals set TERM=xterm).
I attempted to rebuild konsole with FEATURES=test, it passed and I still see hanging stgit. ================================================================= Package Settings ================================================================= kde-base/konsole-4.11.3 was built with the following: USE="test (-aqua) -debug -handbook"
I also notice that the hang does not happen when I ssh to localhost using a konsole that otherwise displays the hanging. Using tmux or screen does not show any change, though.
Next guess: On your hanging box it pipes through less, even when it should not. Do the ~/.gitconfig (or related) differ between your two boxes?
I must correct my earlier statement. The hangs *sometimes* show up in lxterminal. ~/.gitconfig of box with no hangs: [user] name = eroen email = eroen@occam.eroen.eu [push] default = simple ~/.gitconfig of box with hangs: [user] email = eroen@falcon.eroen.eu name = eroen
Err. After an unrelated reboot, I can no longer reproduce the hangs in konsole, but the *occasional* hangs in lxterminal are still present. I suspect konsole reuses an existing process or something, so I was not using the newly rebuilt one. I can also reproduce the hangs with the 'vte' terminal emulator, but not with 'vte2_90'.
I no longer see this issue after updating and rebuilding many things over a few weeks. It may not be reproducible at all.
