The argv_array API is useful for not just managing argv but any "vector" (NULL-terminated array) of strings, and has seen adoption to a certain degree. It has been renamed to "strvec" to reduce the barrier to adoption. * jk/strvec: strvec: rename struct fields strvec: drop argv_array compatibility layer strvec: update documention to avoid argv_array strvec: fix indentation in renamed calls strvec: convert remaining callers away from argv_array name strvec: convert more callers away from argv_array name strvec: convert builtin/ callers away from argv_array name quote: rename sq_dequote_to_argv_array to mention strvec strvec: rename files from argv-array to strvec argv-array: rename to strvec argv-array: use size_t for count and alloc
2020-08-03upload-pack.c: introduce 'uploadpackfilter.tree.maxDepth'Libravatar Taylor Blau1-0/+18
In b79cf959b2 (upload-pack.c: allow banning certain object filter(s), 2020-02-26), we introduced functionality to disallow certain object filters from being chosen from within 'git upload-pack'. Traditionally, administrators use this functionality to disallow filters that are known to perform slowly, for e.g., those that do not have bitmap-level filtering. In the past, the '--filter=tree:<n>' was one such filter that does not have bitmap-level filtering support, and so was likely to be banned by administrators. However, in the previous couple of commits, we introduced bitmap-level filtering for the case when 'n' is equal to '0', i.e., as if we had a '--filter=tree:none' choice. While it would be sufficient to simply write $ git config uploadpackfilter.tree.allow true (since it would allow all values of 'n'), we would like to be able to allow this filter for certain values of 'n', i.e., those no greater than some pre-specified maximum. In order to do this, introduce a new configuration key, as follows: $ git config uploadpackfilter.tree.maxDepth <m> where '<m>' specifies the maximum allowed value of 'n' in the filter 'tree:n'. Administrators who wish to allow for only the value '0' can write: $ git config uploadpackfilter.tree.allow true $ git config uploadpackfilter.tree.maxDepth 0 which allows '--filter=tree:0', but no other values.

2020-08-03upload-pack.c: allow banning certain object filter(s)Libravatar Taylor Blau1-0/+86
Git clients may ask the server for a partial set of objects, where the set of objects being requested is refined by one or more object filters. Server administrators can configure 'git upload-pack' to allow or ban these filters by setting the 'uploadpack.allowFilter' variable to 'true' or 'false', respectively. However, administrators using bitmaps may wish to allow certain kinds of object filters, but ban others. Specifically, they may wish to allow object filters that can be optimized by the use of bitmaps, while rejecting other object filters which aren't and represent a perceived performance degradation (as well as an increased load factor on the server). Allow configuring 'git upload-pack' to support object filters on a case-by-case basis by introducing two new configuration variables: - 'uploadpackfilter.allow' - 'uploadpackfilter.<kind>.allow' where '<kind>' may be one of 'blobNone', 'blobLimit', 'tree', and so on. Setting the second configuration variable for any valid value of '<kind>' explicitly allows or disallows restricting that kind of object filter. If a client requests the object filter <kind> and the respective configuration value is not set, 'git upload-pack' will default to the value of 'uploadpackfilter.allow', which itself defaults to 'true' to maintain backwards compatibility. Note that this differs from 'uploadpack.allowfilter', which controls whether or not the 'filter' capability is advertised.

2020-07-30strvec: rename struct fieldsLibravatar Jeff King1-1/+1
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 King1-2/+1
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 King1-24/+24
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.

2020-07-16upload-pack: do not lazy-fetch "have" objectsLibravatar Jonathan Tan1-2/+4
When upload-pack receives a request containing "have" hashes, it (among other things) checks if the served repository has the corresponding objects. However, it does not do so with the OBJECT_INFO_SKIP_FETCH_OBJECT flag, so if serving a partial clone, a lazy fetch will be triggered first. This was discovered at $DAYJOB when a user fetched from a partial clone (into another partial clone - although this would also happen if the repo to be fetched into is not a partial clone). Therefore, whenever "have" hashes are checked for existence, pass the OBJECT_INFO_SKIP_FETCH_OBJECT flag. Also add the OBJECT_INFO_QUICK flag to improve performance, as it is typical that such objects do not exist in the serving repo, and the consequences of a false negative are minor (usually, a slightly larger pack sent).

2020-06-10upload-pack: send part of packfile response as uriLibravatar Jonathan Tan1-6/+71
Teach upload-pack to send part of its packfile response as URIs. An administrator may configure a repository with one or more "uploadpack.blobpackfileuri" lines, each line containing an OID, a pack hash, and a URI. A client may configure fetch.uriprotocols to be a comma-separated list of protocols that it is willing to use to fetch additional packfiles - this list will be sent to the server. Whenever an object with one of those OIDs would appear in the packfile transmitted by upload-pack, the server may exclude that object, and instead send the URI. The client will then download the packs referred to by those URIs before performing the connectivity check.

This is a behavior change, as we accidentally used to let values in those bitfields propagate from one v2 "fetch" command to another for ssh/git/file connections (but not for http). That's fixing a bug, but one nobody is likely to see, because it would imply the client sending different capabilities for each request.
