2020-07-30strvec: rename struct fieldsLibravatar Jeff King1-4/+4
The "argc" and "argv" names made sense when the struct was argv_array, but now they're just confusing. Let's rename them to "nr" (which we use for counts elsewhere) and "v" (which is rather terse, but reads well when combined with typical variable names like "args.v"). Note that we have to update all of the callers immediately. Playing tricks with the preprocessor is hard here, because we wouldn't want to rewrite unrelated tokens.

2020-07-28strvec: fix indentation in renamed callsLibravatar Jeff King1-3/+3
Code which split an argv_array call across multiple lines, like: argv_array_pushl(&args, "one argument", "another argument", "and more", NULL); was recently mechanically renamed to use strvec, which results in mis-matched indentation like: strvec_pushl(&args, "one argument", "another argument", "and more", NULL); Let's fix these up to align the arguments with the opening paren. I did this manually by sifting through the results of: git jump grep 'strvec_.*,$' and liberally applying my editor's auto-format. Most of the changes are of the form shown above, though I also normalized a few that had originally used a single-tab indentation (rather than our usual style of aligning with the open paren). I also rewrapped a couple of obvious cases (e.g., where previously too-long lines became short enough to fit on one), but I wasn't aggressive about it. In cases broken to three or more lines, the grouping of arguments is sometimes meaningful, and it wasn't worth my time or reviewer time to ponder each case individually.

2020-07-28strvec: convert remaining callers away from argv_array nameLibravatar Jeff King1-18/+18
We eventually want to drop the argv_array name and just use strvec consistently. There's no particular reason we have to do it all at once, or care about interactions between converted and unconverted bits. Because of our preprocessor compat layer, the names are interchangeable to the compiler (so even a definition and declaration using different names is OK). This patch converts all of the remaining files, as the resulting diff is reasonably sized. The conversion was done purely mechanically with: git ls-files '*.c' '*.h' | xargs perl -i -pe ' s/ARGV_ARRAY/STRVEC/g; s/argv_array/strvec/g; ' We'll deal with any indentation/style fallouts separately.

2020-07-28strvec: rename files from argv-array to strvecLibravatar Jeff King1-1/+1
This requires updating #include lines across the code-base, but that's all fairly mechanical, and was done with: git ls-files '*.c' '*.h' | xargs perl -i -pe 's/argv-array.h/strvec.h/' Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2019-12-05quote-stress-test: offer to test quoting arguments for MSYS2 shLibravatar Johannes Schindelin1-3/+10
It is unfortunate that we need to quote arguments differently on Windows, depending whether we build a command-line for MSYS2's `sh` or for other Windows executables. We already have a test helper to verify the latter, with this patch we can also verify the former. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>

2019-12-05quote-stress-test: accept arguments to test via the command-lineLibravatar Johannes Schindelin1-13/+22
When the stress test reported a problem with quoting certain arguments, it is helpful to have a facility to play with those arguments in order to find out whether variations of those arguments are affected, too. Let's allow `test-run-command quote-stress-test -- <args>` to be used for that purpose. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
2019-12-05tests: add a helper to stress test argument quotingLibravatar Garima Singh1-2/+116
On Windows, we have to do all the command-line argument quoting ourselves. Worse: we have to have two versions of said quoting, one for MSYS2 programs (which have their own dequoting rules) and the rest. We care mostly about the rest, and to make sure that that works, let's have a stress test that comes up with all kinds of awkward arguments, verifying that a spawned sub-process receives those unharmed.

2019-11-23mingw: demonstrate that all file handles are inherited by child processesLibravatar Johannes Schindelin1-0/+44
When spawning child processes, we really should be careful which file handles we let them inherit. This is doubly important on Windows, where we cannot rename, delete, or modify files if there is still a file handle open.

2019-10-06test-tool run-command: learn to run (parts of) the testsuiteLibravatar Johannes Schindelin1-0/+153
Git for Windows jumps through hoops to provide a development environment that allows to build Git and to run its test suite. To that end, an entire MSYS2 system, including GNU make and GCC is offered as "the Git for Windows SDK". It does come at a price: an initial download of said SDK weighs in with several hundreds of megabytes, and the unpacked SDK occupies ~2GB of disk space. A much more native development environment on Windows is Visual Studio. To help contributors use that environment, we already have a Makefile target `vcxproj` that generates a commit with project files (and other generated files), and Git for Windows' `vs/master` branch is continuously re-generated using that target. The idea is to allow building Git in Visual Studio, and to run individual tests using a Portable Git. The one missing thing is a way to run the entire test suite: neither `make` nor `prove` are required to run Git, therefore Git for Windows does not support those commands in the Portable Git. To help with that, add a simple test helper that exercises the `run_processes_parallel()` function to allow for running test scripts in parallel (which is really necessary, especially on Windows, as Git's test suite takes such a long time to run). This will also come in handy for the upcoming change to our Azure Pipeline: we will use this helper in a Portable Git to test the Visual Studio build of Git.

GIT_TRACE prints just the command line which makes it hard to tell that it's not really executed on this repository. Print the env delta (compared to parent environment) in this case.

Replace uses of strbuf_addf() for adding strings with more lightweight strbuf_addstr() calls.
